Description

Technical Field

[0001] This utility model relates to the field of pneumatic actuator technology, and in particular to a quick-assembly and disassembly pneumatic actuator and a matching quick-assembly main component. Background Technology

[0002] Pneumatic actuators, as key components in automated control systems, are widely used in industrial automation equipment to drive the movement of valves and other devices. However, the existing installation and disassembly processes for pneumatic actuators have certain limitations, especially when each actuator needs to be inspected individually before leaving the factory. Traditional installation methods often result in cumbersome operations and low efficiency. In current technology, pneumatic actuators are typically fixed to the valve body with bolts. While this method ensures stability, it lacks flexibility in terms of rapid disassembly, installation, and positioning, and cannot provide an effective solution, especially for the needs of mass production and individual inspection.

[0003] Therefore, simplifying the installation and disassembly process of pneumatic actuators, improving the efficiency of individual inspection, and enabling rapid and accurate positioning have become urgent technical problems to be solved. Utility Model Content

[0043] This embodiment also provides a variety of assembly methods when the pneumatic actuator body 11 cannot be assembled with the valve body by bolts in a confined space.

[0044] The working principle of this embodiment is as follows:

[0045] After pulling the right-hand pull block 23, the locking block can be used to limit the movement; then apply force to the wave-moving section 85 to move the side pressure claw 83 away from the quick-release area, and then insert the quick-release plate 14 into the quick-release area; the side support block 72 and the two lower support blocks 71 can contact the quick-release plate 14 inserted into the quick-release area for support and positioning.

[0046] Then remove the limit on the pull block 23 and release the side pressure claw 83. The four main pressure claws 31 will press and fix the quick-release plate 14 by cooperating under the driving force of the main spring 42 and the side pressure claws 83 will be driven by the auxiliary spring 84.

[0047] The quick-release process is as follows:

[0048] After pulling the right-hand pull block 23, the locking block can be used to limit the movement; then apply force to the wave-pulling section 85 to move the side pressure claw 83 away from the quick-release area, and then directly remove the pneumatic actuator body 11.
