Description

Technical Field

[0001] The utility model belongs to the technical field of fixed fixtures, and particularly relates to a fixed fixture for processing air compressor pistons. Background Technique

[0002] A fixed fixture is a device used to fix the processing object during the mechanical manufacturing process, also known as a fixture. Its main function is to fix the workpiece so that it can maintain the correct position during processing or detection. The fixed fixture can ensure the stability of the workpiece during the processing process, thereby improving the processing accuracy and efficiency. They are widely used in various industries, including metal processing, woodworking, electronics, automotive, aerospace, etc.

[0003] The model number of the existing fixed fixture for processing air compressor pistons is fixed, and it can only clamp and fix air compressor pistons with a fixed diameter, with single functionality. As a result, the application scenarios of the fixed fixture for processing air compressor pistons are relatively limited. Therefore, a fixed fixture for processing air compressor pistons is needed to solve the above problems. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a fixed fixture for processing air compressor pistons to solve the problems raised in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A fixed fixture for processing air compressor pistons, including an installation base and a fixed ring. An internal and external clamping device is arranged on the top of the installation base. The internal and external clamping device includes a guide block. Two limit fixing plates are fixedly connected to the top of the guide block. A first convex slider and a second convex slider are slidably connected to the surface of the guide block. A bidirectional threaded rod is threadedly connected inside the first convex slider and the second convex slider. An anti-slip rotating handle is fixedly connected to one side of the bidirectional threaded rod. A bearing is fixedly connected to the side of the limit fixing plate away from the bidirectional threaded rod. An arc-shaped protective plate is fixedly connected to the bottom of the two limit fixing plates. A first inner clamping plate is fixedly connected to the top of the first convex slider. A first connecting plate is fixedly connected to one side of the first convex slider.

A second outer clamping plate is fixedly connected to the side of the second connecting plate close to the fixed ring.

[0006] By setting the above structure, when it is necessary to clamp and fix the air compressor pistons with different diameters, first place the air compressor piston into the piston placement groove inside the fixed ring. At this time, rotate the bidirectional threaded rod. The rotation of the bidirectional threaded rod can cause the first inner clamping plate and the second inner clamping plate, and the first outer clamping plate and the second outer clamping plate to clamp and fix the inner and outer walls of the air compressor piston respectively. Moreover, the bidirectional threaded rod can adjust the relative clamping distance of the four clamping plates according to the specific diameter of the air compressor piston and achieve the clamping and fixing of air compressor pistons with different diameters, enabling the fixing fixture for air compressor piston processing to flexibly and conveniently clamp and fix air compressor pistons of different models, thereby enhancing the functionality of the fixing fixture for air compressor piston processing and having a wider range of application scenarios.

A bearing 507 is fixedly connected to the side of the limit fixing plate 502 away from the bidirectional threaded rod 505. An arc-shaped protection plate 508 is fixedly connected to the bottom of the two limit fixing plates 502. A first inner clamping plate 509 is fixedly connected to the top of the first convex slider 503. A first connecting plate 510 is fixedly connected to one side of the first convex slider 503. A first outer clamping plate 511 is fixedly connected to the side of the first connecting plate 510 close to the fixed ring 3. A second inner clamping plate 512 is fixedly connected to the top of the second convex slider 504. A second connecting plate 513 is fixedly connected to one side of the second convex slider 504. A second outer clamping plate 514 is fixedly connected to the side of the second connecting plate 513 close to the fixed ring 3. By setting the bidirectional threaded rod 505, the first inner clamping plate 509, the second inner clamping plate 512, the first outer clamping plate 511 and the second outer clamping plate 514, when it is necessary to clamp and fix an air compressor piston with different diameters, first place the air compressor piston into the piston placement groove 4 inside the fixed ring 3. At this time, rotate the bidirectional threaded rod 505. The rotation of the bidirectional threaded rod 505 can enable the first inner clamping plate 509 and the second inner clamping plate 512, and the first outer clamping plate 511 and the second outer clamping plate 514 to clamp and fix the inner and outer walls of the air compressor piston respectively.

[0028] The working principle and usage process of the present utility model: When it is necessary to clamp and fix the air compressor piston with different diameters, first place the air compressor piston into the piston placement groove 4 inside the fixing ring 3, hold the anti-slip rotating handle 506 and rotate it. The rotation of the anti-slip rotating handle 506 will drive the bidirectional threaded rod 505 fixedly connected to it to rotate inside the two limiting fixing plates 502 and the bearing 507. At this time, the first convex slider 503 and the second convex slider 504 threadedly connected to the bidirectional threaded rod 505 will slide relatively on the surface of the guiding block 501. The first inner clamping plate 509 and the second inner clamping plate 512 fixedly connected to the first convex slider 503 and the second convex slider 504 respectively will also move relatively. At this time, the first inner clamping plate 509 and the second inner clamping plate 512 apply clamping forces to both sides of the inner wall of the air compressor piston.

At this time, the first outer clamping plate 511 and the second outer clamping plate 514 will apply clamping forces to both sides of the outer wall of the air compressor piston. Under the clamping forces on the inner and outer sides, the inner wall and the outer wall of the air compressor piston can be clamped simultaneously and synchronously, and thus the clamping and fixing function of the air compressor piston can be realized flexibly and conveniently according to the specific diameter of the air compressor piston.
