Abstract
Description
Technical Field
[0001] This utility model relates to the field of pneumatic actuator technology, specifically a fixed tooling for machining the piston of a pneumatic actuator. Background Technology
[0002] A pneumatic actuator is a device that uses air pressure to open, close, or regulate a valve; it is also called a pneumatic actuator mechanism or pneumatic device. The piston is a crucial component of the pneumatic actuator. Compressed gas drives the piston to move within a cylinder to open and close the valve. The piston's structure is as follows: Figure 1 As shown, it is necessary to slot its outer surface, so it needs to be fixed. The existing clamping mechanism is complex and requires multiple clamping mechanisms to be designed for pistons of different sizes, resulting in high operating costs. Summary of the Invention
[0003] To solve the above-mentioned technical problems, this utility model provides a fixing fixture for processing pneumatic actuator pistons, which can easily fix the piston, has a simple structure, strong versatility, and reduces processing costs.
[0004] The technical solution is as follows: a fixed tooling for processing a pneumatic actuator piston, characterized in that it includes a clamping seat, one end of which is fixedly connected to one end of a positioning seat, the top of which is a positioning plane and a positioning protrusion is provided on the positioning plane, the other end of which is provided with an adjustable positioning post, a movable locking ring is fitted on the positioning seat, and a locking bolt is provided on the locking ring.
[0005] A further feature is that a positioning plate is provided at one end of the clamping body facing the positioning seat, and a positioning notch is provided on the upper part of the positioning plate;
[0006] The locking bolt is located at the lower part of the locking ring;
[0007] The adjustable positioning post is provided with a screw, which is threadedly connected to the positioning seat.
[0008] By adopting this utility model, the toothed part of the piston is fastened onto the positioning seat, and the positioning protrusion and teeth cooperate to prevent movement. The piston body part abuts against the adjustable positioning post to achieve positioning. Finally, after putting on the locking ring, the piston is locked with the locking bolt, which can easily fix the piston. The structure is simple, versatile, and reduces processing costs.

[0012] Figure 4 for Figure 2 Diagram of direction A in the middle. Detailed Implementation
[0013] See Figures 1 to 4 As shown, a fixed fixture for processing a pneumatic actuator piston includes a clamping base 1. One end of the clamping base 1 is fixedly connected to one end of a positioning base 2. The top of the positioning base 2 is a positioning plane 3, and a positioning protrusion 4 is provided on the positioning plane 3. The longitudinal section of the positioning protrusion 4 is triangular and is used to cooperate with the rack on the piston. An adjustable positioning pin 5 is provided at the other end of the positioning base 2 to abut against the piston body for positioning. A movable locking ring 6 is fitted on the positioning base 2, and a locking bolt 7 is provided on the locking ring 6. The locking bolt 7 is located at the lower part of the locking ring 6.
[0014] A positioning plate 8 is provided at one end of the clamping body 1 facing the positioning seat 2. The upper part of the positioning plate 8 is provided with a positioning notch 9, which is used for some long pistons so that the piston end can be positioned against the back.
[0015] The adjustable positioning pin 5 is equipped with a screw 10, which is threadedly connected to the positioning seat 2. It can be adjusted by screwing, and is suitable for pistons of different sizes.
[0016] In use, first remove the locking ring 6, then press the rack part of the piston against the positioning plane 3 so that the positioning protrusion 4 is engaged between two teeth, and the piston body presses against the adjustable positioning post 5 to achieve positioning. Then, put the locking ring 6 on the piston, and press the locking bolt 7 against the lower part of the positioning seat 2. Then, tighten the locking bolt 7 so that the locking ring 6 can be continuously tightened, pressing the piston against the positioning seat 2 to complete the piston fixation. Then, install the clamping seat 1 into the machine tool to process the piston. The position of the locking ring 6 can be adjusted according to the processing position to avoid positional errors.
