Abstract
The utility model discloses a piston fixture for machining an inner pin hole of a piston. The piston fixture for machining the inner pin hole of the piston comprises a base. The base is provided with a positioning base matching with a stopping hole machining inner hole of the piston, a positioning block fitting with the side surface of an inner pin hole base of the piston and an elastic stopping block abutting against the other side surface of the inner pin hole base of the piston. According to the piston fixture for machining the inner pin hole of the piston, the piston can be automatically rotated to the place by the elastic stopping block when the piston is disposed in the piston fixture by a worker, so that the time of disposing and clamping is reduced, and the production efficiency is improved.
Description
Technical field
The utility model relates to a kind of piston tool of machining piston inner pinhole.
Background technology
The piston inner pinhole is structure important in the piston, and therefore, the inner pinhole requirement on machining accuracy is higher, during the processing inner pinhole, generally all will carry out bore hole and reach required precision.In addition, the end face of piston inner pinhole seat and pin-and-hole generally have the perpendicularity requirement.
According to shown in Figure 1, the piston inner pinhole in boring process, with the seam of piston processing endoporus as the location benchmark, with the side of inner pinhole seat as the location benchmark that rotates.The piston tool of existing machining piston inner pinhole comprises base 01, positioning seat 02 and limited block 03.Before bore hole, the seam processing inner hole sleeve with piston is located on the positioning seat 02 of piston tool in advance, and the angle that piston rotation is certain, and the side of piston inner pinhole seat and limited block 03 are adjacent to, and the cylinder clamping piston begins bore hole then.Because output piston is big, the operative employee can forget rotating piston once in a while or rotate not in placely when positioning piston, cause the side of inner pinhole seat not to be adjacent to limited block 03, thereby can not guarantee the end face of piston inner pinhole seat and the perpendicularity of inner pinhole, and the precision of inner pinhole does not reach requirement yet.
Summary of the invention
The purpose of this utility model is to overcome deficiency of the prior art, and the piston tool of a kind of accurately positioning piston, the machining piston inner pinhole of shortening clamping time is provided.
To achieve these goals, the utility model is by the following technical solutions:
A kind of piston tool of machining piston inner pinhole, comprise base, base is provided with the positioning seat that cooperates with piston seam processing endoporus and the limited block that is adjacent to piston inner pinhole seat side, also is provided with flexible block on the described base, and flexible block leans the another side at piston inner pinhole seat.
Described flexible block comprises bearing and the block that is fixed on the base, and block rotates by bearing pin and is arranged on the bearing, is provided with return spring between the bottom of block and the bearing.
The upper surface of described positioning seat is provided with equally distributed boss more than three.Can reduce the working (finishing) area of positioning seat upper surface with the boss location, reduce cost.
Described boss is four.Four boss can be realized the location better.
The utility model adopts above technical scheme, and when the operative employee packed piston into the piston tool, flexible block leaned in the another side of piston inner pinhole seat, and flexible block automatically is rotated in place piston, has shortened the clamping time, has improved production efficiency.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further elaborated;
Fig. 1 is the work schematic diagram of the piston tool of existing machining piston inner pinhole;
Fig. 2 is the front view of the piston tool of a kind of machining piston inner pinhole of the utility model;
Fig. 3 is the vertical view of the piston tool of a kind of machining piston inner pinhole of the utility model;
Fig. 4 is the work schematic diagram of the piston tool of a kind of machining piston inner pinhole of the utility model.
The specific embodiment
Shown in one of Fig. 2 to Fig. 4, the piston tool of a kind of machining piston inner pinhole of the utility model, comprise base 1, base 1 is provided with the positioning seat 2 that cooperates with piston seam processing endoporus and the limited block 3 that is adjacent to piston inner pinhole seat side, also be provided with flexible block 4 on the described base 1, flexible block 4 leans the another side at piston inner pinhole seat.
Described flexible block 4 comprises bearing 41 and the block 42 that is fixed on the base 1, and block 42 rotates by bearing pin 43 and is arranged on the bearing 41, is provided with return spring 44 between the bottom of block 42 and the bearing 41.
The upper surface of described positioning seat 2 is provided with equally distributed boss 21 more than three.Can reduce the working (finishing) area of positioning seat 2 upper surfaces with boss 21 location, reduce cost.
Described boss 21 is four.Four boss 21 can be realized the location better.
Be provided with a flexible block 4 at base 1, when the operative employee packed piston into the piston tool, flexible block 4 leaned in the another side of piston inner pinhole seat, and flexible block 4 automatically is rotated in place piston, has shortened the clamping time, has improved production efficiency.
