The utility model discloses a piston salt core fixing device fixes the salt core at piston casting in-process, and the structure is succinct, and is practical convenient.
Description
Technical Field
The utility model belongs to piston production and processing equipment especially relates to a piston salt core fixing device.
Background
The piston is an important engine component, and the piston needs a preset groove and a preset hole in the casting process. The grooves and holes are generally formed by presetting a salt core. When presetting the salt core, need fix, support the salt core, because of the groove of piston, the hole is to the required precision is higher, requires the salt core location stable, prevents that the salt core displacement from causing product casting failure (groove, hole size deviation).
Disclosure of Invention
An object of the utility model is to overcome prior art's defect, provide a piston salt core fixing device that the structure is succinct, the reliability is high.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
a piston salt core fixing device comprises a supporting seat, a supporting rod fixedly connected with the supporting seat, a clamp spring fixedly arranged in the supporting seat and a supporting rib connected with the supporting rod; the lower end of the support rib extends into the support seat from the through hole in the middle of the support rod and is clamped by the clamp spring; the upper end of the supporting rib is fixedly connected with the salt core to be supported; the bottom of the supporting seat 1 is provided with a detachable rear plug.
Preferably, the clamp spring comprises two arc bending parts which are symmetrically arranged, the two arc bending parts are fixedly arranged at two ends of the arc bending part respectively, the lower end of the arc bending part is abutted with the rear plug, and the upper end of the arc bending part is abutted with the upper part of the inner cavity of the support seat; when the support rib is used, the lower end of the support rib is clamped between the two arc bending parts.
Preferably, the support bar is a cone.
The utility model discloses a piston salt core fixing device fixes the salt core at piston casting in-process, and the structure is succinct, and is practical convenient.
Drawings
Fig. 1 is a schematic structural diagram of the present invention;
fig. 2 is a schematic structural diagram of a clamp spring in an embodiment of the present invention;
in the attached drawing, a support seat 1, a support rod 2, a clamp spring 3, a support rib 4, a rear plug 5, a circular arc bent part 6, an arc bent part 7, an inner cavity of the support seat 8 and a salt core A.
Detailed Description
The following examples are given in conjunction with the accompanying drawings to further illustrate the embodiments of the present invention. The present invention is not limited to the description of the following embodiments.
Embodiment 1, as shown in the drawings, the present embodiment discloses a piston salt core fixing device, which is mainly used for supporting and fixing a preset salt core a in a piston casting process, and when the piston salt core fixing device is used, the piston salt core fixing device is arranged singly or in groups or symmetrically, and supports different positions of the salt core a according to the casting design requirements. Specifically, the method comprises the following steps: the support comprises a support seat 1, a support rod 2 fixedly connected with the support seat 1, a clamp spring 3 fixedly arranged in the support seat 1 and a support rib 4 connected with the support rod 2;
the lower end of the support rib 4 extends into the support seat 1 (inner cavity 8) from a through hole in the middle of the support rod 2 and is clamped by the clamp spring 3;
the upper end of the support rib 4 is fixedly connected with a salt core A to be supported;
the bottom of the supporting seat 1 is provided with a detachable rear plug 5. And after disassembly, the plug 5 is subjected to operations such as replacement and overhaul of the clamp spring 3.
Preferably, the clamp spring 3 comprises two arc bending parts 6 which are symmetrically arranged, the two arc bending parts 6 are respectively and fixedly arranged at two ends of the arc bending part 7, the lower end of the arc bending part 7 is abutted with the rear plug 5, and the upper end of the arc bending part 6 is abutted with the upper part of the inner cavity 8 of the support seat 1; when in use, the lower end of the support rib 4 is clamped between the two arc bending parts 6. The clamp spring 3 is formed by continuously bending a metal material, and the upper end and the lower end of the clamp spring are respectively arranged in the inner cavity 8 of the supporting seat 1 in an overhead mode.
When fixing salt core A, fixed (directly with salt core A predetermine fixed orifices fixed linking to each other or adopt fixed connection modes such as bolt fixed connection) with the salt core A upper end of brace rod 4, the 4 lower extremes of brace rod insert bracing piece 2 and by 3 chucking of jump ring, prevent salt core A come-up and dislocation.
Preferably, the support bar 2 is a cone.
The foregoing is a more detailed description of the present invention, taken in conjunction with the specific preferred embodiments thereof, and it is not intended that the invention be limited to the specific embodiments shown and described. To the utility model belongs to the technical field of ordinary technical personnel, do not deviate from the utility model discloses under the prerequisite of design, can also make a plurality of simple deductions or replacement, all should regard as belonging to the utility model discloses a protection scope.
