Description

The milling device

The utility model relates to the Metal Cutting Machine Tool technical field, is a kind of for enlarging the multi-functional milling device that the lathe function of use is added.

At present all kinds of lathes that use all are single function lathes, can not a tractor serves several purposes, thereby operations such as milling during machined, mill, car, all must be provided with and mill, grind lathe etc.This just needs bigger investment.Centering minicomputer process unit particularly, it is in demand finishing multiple machining processes with less investment.

The purpose of this utility model is, a kind of milling device is provided, be installed on the lathe and use, make it not only can finish the turning function that has possessed, but also can be to the plane of axle, sleeve workpiece and keyway milling processing and to foreign round, the grinding of endoporus and end face, and simple in structure, easy for installation, flexible operation, cheap advantage are arranged.

The technical solution of the utility model is: the milling device is installed on the knife rest (B) of lathe, main shaft (13) is installed in the hole of milling body (16), main shaft (13) one ends dress drill chuck (17), the other end dress driven pulley (12) of main shaft (13), transmission case (7) connects with milling body (16), and adjustment rack (3) and gear (4), gear (6) are installed in the transmission case (7).Cover (10), emery wheel (11) and emery wheel clamp nut (9) in the emery wheel can be installed in the termination of main shaft (13), in the outside of gear (4) regulating wheel (5) is installed.

Description of drawings: accompanying drawing 1 is installation site figure of the present utility model; Accompanying drawing 2 is the E-E cutaway views in the accompanying drawing 1; Accompanying drawing 3 is structure charts that grinding wheel spindle (15) and interior grinding abrasive disk (14) can be installed in the termination of main shaft (13).

The contrast accompanying drawing elaborates to the utility model:

(1) is motor among the figure, and (2) are mounted in the belt wheel on the defeated axle of motor.Milling body (16) is installed on the lathe saddle (B), main shaft (13) is installed in the hole of milling body (16), one end of main shaft (13) has the short awl of Mohs, and drill chuck (17) is housed, belt wheel (12) is installed in the other end of main shaft (13), cover (10), emery wheel (11) and emery wheel clamp nut (9) in the emery wheel shown in Figure 2 can be installed in the termination of main shaft (13), and interior frosted wheel shaft (15) shown in Figure 3 and interior grinding abrasive disk (14) also can be installed.Transmission case (7) is installed on the milling body (16), its inner adjustment rack (3) of installing, the gear pair that commutation driving gear (4) and commutation driven gear (6) are formed is housed on the adjustment rack (3), the outside at commutation driving gear (4) is provided with a regulating wheel (5), with the degree of tightness that adjusts the grinding driving-belt.Milling body (16) is provided with the opening that the folder cutter groove with lathe saddle (B) matches, and is convenient to the usefulness of clamping.

When the utility model is installed and used, be installed on the knife rest (B) of lathe, its alignment of shafts height (A line) is identical with the lathe centre-height, according to using needs, its device is rotated around knife rest (B) central axis (C), can realize that milling cutter or emery wheel are in Working position, lock knife rest then, just can carry out milling and grinding.

The utility model is installed on the lathe and uses easily, and it can make lathe have Several functions, except turning, can be to plane and the keyway milling of axle, sleeve workpiece Processing and to foreign round, the grinding of endoporus and end face. The utility model also has knot Structure is simple, easy for installation, flexible operation, cheap advantage.

Claims (3)

1, milling device, it is characterized in that it is installed on the knife rest of lathe (B), main shaft (13) is installed in the hole of milling body (16), main shaft (13) one ends dress drill chuck (17), the other end dress driven pulley (12) of main shaft (13), transmission case (7) connects with milling body (16), and adjustment rack (3) and gear (4), gear (6) are installed in the transmission case (7).

2, according to the described milling device of claim 1, it is characterized in that: cover (10) in the emery wheel, emery wheel (11) and emery wheel clamp nut (9) can be installed in the termination of main shaft (13).
