Abstract
The utility model discloses a rotary sewing platform base for a sewing machine, which comprises a rotary sewing platform base for a sewing machine, wherein the rotary sewing platform base is combined with a small bearing, a transmission synchronous belt pulley seat, a big bearing of a thrusting needle bearing and a bearing sleeve. The utility model can ensure that the rotary sewing platform can keep balanced and stable in work, which makes sewing line shape beautiful and sewing dense uniform and makes sewing accurately positioned, and an ideal sewing effect can be achieved; simultaneously, the condition that as components are damaged beforehand, the performance of a sewing machine and the service life of a machine are affected.
Description
Technical field
The utility model relates to a kind of rotary sewing platform base for sewing machine.
Background technology
The plane formula flatcar is all adopted in the production of suitcase the earliest, is difficult to competent modern production needs.Back design innovation goes out a kind of flatcar with crankshaft rocker, and this patent No. is 02281700.x, and name is called the utility model patent of the crankshaft rocker pedestal of suitcase tailoring machine.Because the center of gravity of curved rocking arm is big from equalizer bearing group switching centre distance, produce bigger gravitational moment in this design; And the rhythm pressure of press material structure in real work, produce bigger oscillatory torque, also be delivered to the equalizer bearing group by curved rocker arm shaft, and this equalizer bearing group diameter is little, stressed radius is little, be difficult to the above-described gravitational moment of balance and oscillatory torque, so that curved rocking arm amplitude of fluctuation is big when working, produce the forthright vibration of joint, can't keep stitching the platform stable equilibrium, cause the sewing line style not attractive in appearance, the seam order is inhomogeneous, sewing can not accurately put in place, easily makes simultaneously equalizer bearing group parts impaired and affect sewing machine performance and machine service life.
The utility model content
The utility model technical issues that need to address just are to overcome the defective of prior art, a kind of rotary sewing platform base for sewing machine is provided, it can guarantee that revolution seam platform keeps balance and stability at work, so that the sewing line style is attractive in appearance, the seam order is even, sewing can accurately put in place, reaches comparatively ideal sewing efficiency; Avoided simultaneously because parts too early impaired, and affected sewing machine performance and machine service life.
For addressing the above problem, the utility model adopts following technical scheme:
The utility model rotary sewing platform base for sewing machine, comprise sewing machine revolution seam pedestal, revolution seam pedestal makes up little bearing, transmission synchronous belt wheel base, the big bearing of thrust needle roller, bearing holder (housing, cover), described transmission synchronous belt wheel base makes up little bearing by the assembling of the axle on it revolution seam pedestal and is installed in the revolution seam pedestal, between seam pedestal top, transmission synchronous belt wheel base and the seam pedestal, the outside that is sheathed on the seam pedestal is equipped with the big bearing of thrust needle roller, cover has bearing holder (housing, cover) on it, and the transmission synchronous belt wheel base is installed on the bearing holder (housing, cover).
Described pedestal is installed in below the curved rocker arm shaft revolution of the sewing machine seam platform base, between described revolution seam platform base and revolution seam sewing platform base, also be provided with a Balance Iron, described Balance Iron is installed on the revolution seam platform base by fastening bolt, itself and pedestal abutting end are the convex stepped ramp type, and the convex step surface is held in respectively on bearing holder (housing, cover) and the transmission synchronous belt wheel base.
The utility model is owing to adopt the major diameter needle bearing, and is the outside that is sheathed on revolution seam pedestal, thereby increased stressed radius; Also to a certain extent effectively balance owing to the rhythm pressure of press material structure in the work produces bigger oscillatory torque.Owing to be provided with Balance Iron, it is anchored on the revolution seam platform base, link closely transmission synchronous belt wheel base and bearing holder (housing, cover) installed, because its weight is heavier, effectively balance owing to the center of gravity of curved rocker arm shaft from the gravitational moment that equalizer bearing centre distance produces greatly, make center of gravity be positioned at the center of transmission synchronous pulley; Therefore can guarantee that revolution seam platform keeps balance and stability at work, so that the sewing line style is attractive in appearance, the seam order is even, and sewing can accurately put in place, reaches comparatively ideal sewing efficiency; Avoided simultaneously because parts too early impaired, and affected sewing machine performance and machine service life.

The specific embodiment
As shown in Figure 1 and Figure 2, the utility model Sewing machines revolution seam stylobate seat, comprise Sewing machines revolution seam pedestal 1, revolution seam platform base makes up little bearing 2, transmission synchronous pulley seat 3, the big bearing 4 of thrust needle roller, bearing holder (housing, cover) 5, described transmission synchronous pulley seat makes up little bearing by the 6 assembling revolution seam pedestals of the axle on it and is installed in the revolution seam pedestal, between seam pedestal top, transmission synchronous pulley seat and the seam pedestal, the outside that is sheathed on the seam pedestal is equipped with the big bearing of thrust needle roller, be with bearing holder (housing, cover) on it, transmission synchronous pulley seat is installed on the bearing holder (housing, cover).
Described pedestal is installed in below the curved rocker arm shaft revolution of the sewing machine seam platform base 7, between described revolution seam platform base and revolution seam sewing platform base, also be provided with a Balance Iron 8, described Balance Iron is installed on the revolution seam platform base by fastening bolt, itself and pedestal abutting end are the convex stepped ramp type, and the convex step surface is held in respectively on bearing holder (housing, cover) and the transmission synchronous belt wheel base.
The structure of revolution seam pedestal and transmission synchronous belt wheel base as shown in Figure 3, Figure 4.
Claims (2)
1, a kind of rotary sewing platform base for sewing machine, comprise sewing machine revolution seam pedestal, revolution seam pedestal makes up little bearing, transmission synchronous belt wheel base, the big bearing of thrust needle roller, bearing holder (housing, cover), it is characterized in that: described transmission synchronous belt wheel base is installed in the revolution seam pedestal by the little bearing of the assembling of the axle on it revolution seam platform base combination, between seam pedestal top, transmission synchronous belt wheel base and the seam pedestal, the outside that is sheathed on the seam pedestal is equipped with the big bearing of thrust needle roller, cover has bearing holder (housing, cover) on it, and the transmission synchronous belt wheel base is installed on the bearing holder (housing, cover).
2, rotary sewing platform base for sewing machine as claimed in claim 1, it is characterized in that: described pedestal is installed in below the curved rocker arm shaft revolution of the sewing machine seam platform base, between described revolution seam platform base and revolution seam sewing platform base, also be provided with a Balance Iron, described Balance Iron is installed on the revolution seam platform base by fastening bolt, itself and pedestal abutting end are the convex stepped ramp type, and the convex step surface is held in respectively on bearing holder (housing, cover) and the transmission synchronous belt wheel base.
