Description

Technical Field

[0001] The utility model relates to the technical field of assembly fixtures, in particular to an assembly fixture. Background Art

[0002] A fixture is a device used to fix the object to be processed during the mechanical manufacturing process so that it occupies the correct position for construction or testing. An assembly fixture is a fixture used to position the material for assembly.

[0003] An assembly fixture is generally equipped with a single or double positioning head and a cylinder. The cylinder is used to drive the positioning head to move, and the positioning head and the shell material are pressed and limited. However, due to the complex shape and structure of the shell material and the irregular end wall, the single or double positioning heads set by ordinary tooling are difficult to position and limit the shell material with complex surface wall shape, which makes the shell material unstable during positioning. When more than two positioning heads are used to position the shell material, the end wall of the fixture becomes too bloated and complicated, which increases the manufacturing cost and subsequent maintenance cost of the fixture. Utility Model Content

[0004] The utility model aims to provide an assembly fixture.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] An assembly fixture comprises a base plate, a column is installed on the top wall of the base plate, a top plate is installed on the top of the column, a top oil cylinder is installed on the top of the top plate, a top pressure head is installed on the lower end wall of the top plate close to the top oil cylinder, a positioning plate is installed in the middle of the upper end of the base plate, a shell material is installed on the upper end of the positioning plate, an orientation seat is arranged on the end wall of one side of the base plate close to the positioning plate, an orientation screw is passed through the top of the orientation seat, two side oil cylinders and one side oil cylinder are installed on the left and right ends of the top of the base plate respectively, two side heads are installed on the right end of the two side cylinders, and one side head is installed on the left end of the one side cylinder.

[0007] Preferably, the bottom plate is fixedly connected to the bottom end wall of the column, and the top end wall of the column is fixedly connected to the top plate.

[0008] Preferably, the top plate is fixedly connected to the top oil cylinder, and the top oil cylinder is transmitted to the top pressure head.

[0011] Preferably, the oil cylinder on one side and the mandrel on one side are mutually transmitted, and at the same time, the oil cylinders on both sides and the mandrels on both sides are mutually transmitted.

[0012] The utility model has at least the following beneficial effects:

[0013] 1. The bottom plate is fixed with the column and the top plate in sequence to form a whole. The top oil cylinder is operated to push the top pressure head down to press the top of the shell material placed on the upper end of the positioning plate;

[0014] 2. The directional screw is rotated and displaced along the end wall of the directional seat. The directional screw is used to contact one point of the end wall of the shell material, and cooperates with the one-side plug driven by the one-side cylinder and the two-side plugs driven by the two-side cylinders to position the other two points on the end wall of the shell material, forming a three-point positioning for the shell material, so that the shell material can be positioned quickly and stably with the least positioning heads and cylinders, so as to facilitate the subsequent faster press-fitting processing, and at the same time, the manufacturing cost and the later maintenance cost are lower.
