[0002] The valve actuator housing is an important protective component of the valve actuator. Its main function is to fix and protect the internal components of the valve actuator, prevent the external environment from damaging the internal components, and ensure the normal operation of the valve actuator. The valve actuator housing is usually made of cast iron, aluminum alloy, stainless steel, plastic and other materials. It has the characteristics of corrosion resistance, high pressure resistance, low temperature resistance, etc., and can adapt to various harsh working environments.

[0003] In the prior art, during the processing of the valve actuator housing, the housing needs to be stabilized by a clamping assembly to prevent the housing from shaking during processing and causing the processing position to shift. However, common clamping assemblies require cumbersome operations when fixing the housing at different positions, and multiple assemblies need to be adjusted continuously to complete the fixing of the housing, which affects the subsequent processing efficiency. How to invent a pneumatic valve actuator housing processing device to improve these problems has become an urgent problem to be solved by those skilled in the art. Utility Model Content

[0009] Preferably, the inner wall of the slider is threadedly connected to the outer wall of the first double-headed screw, and both ends of the second double-headed screw are rotatably connected to the inner wall of the positioning frame.

[0010] Preferably, the outer wall of the positioning block is slidably connected to the inner wall of the positioning frame, one end outer wall of the first piston rod is piston-connected to the inner wall of the first piston chamber, and both side walls of both ends of the first spring are fixedly connected to one side of the clamping plate and the positioning block respectively.

[0011] By adopting the above technical solution, the actuator housing is placed in the processing chamber, and then the motor is started to move the two positioning frames closer to each other, and the two sides of the actuator housing are clamped and fixed by the provided clamping plates to ensure the stability during processing and prevent the processing position from shifting.

[0025] To make the purpose, technical solution and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0026] Example, refer to Figures 1 - 5 , a processing device for a pneumatic valve actuator housing, including an equipment body 1 and a positioning frame 7 arranged on the equipment body 1. A processing chamber 2 is opened on one side of the equipment body 1. A slide groove 3 is opened on the inner wall of the processing chamber 2. A first double-headed screw 4 is installed on the inner wall of the slide groove 3. A motor 5 is installed on the outer wall of the equipment body 1 close to the first double-headed screw 4. Anti-slip strips 6 are installed on the inner walls of the two bottom ends of the equipment body 1 close to the slide groove 3;

[0027] Two positioning frames 7 are symmetrically installed at both ends of the processing chamber 2 respectively. A slide block 8 which is fixedly connected to the lower end of the positioning frame 7 and slidably connected to the inner wall of the slide groove 3 is provided. A second double-headed screw 9 is installed on the inner walls of both ends of the positioning frame 7. A knob 10 is installed at one end of one of the second double-headed screws 9. Symmetrical positioning blocks 11 are installed on the inner walls of both sides of the positioning frame 7. A first piston chamber 12 is opened inside one end of the positioning block 11. A first piston rod 13 is installed on the inner wall of the first piston chamber 12. A clamping plate 14 is installed at one end of the first piston rod 13. A first spring 15 is installed on the outer wall of one side of the clamping plate 14.

[0028] Furthermore; both ends of the first double-headed screw 4 are rotatably connected to the inner walls of both sides of the processing chamber 2. The output end of the motor 5 is fixedly connected to one end of the first double-headed screw 4. The inner wall of the slide block 8 is threadedly connected to the outer wall of the first double-headed screw 4. Both ends of the second double-headed screw 9 are rotatably connected to the inner wall of the positioning frame 7. The outer wall of the positioning block 11 is slidably connected to the inner wall of the positioning frame 7. One end outer wall of the first piston rod 13 is piston-connected to the inner wall of the first piston chamber 12. Both ends of the side wall of the first spring 15 are fixedly connected to one side of the clamping plate 14 and the positioning block 11 respectively.

[0029] It should be noted that: The actuator housing is placed in the processing chamber 2. The knob 10 is rotated according to the width of the actuator housing, so that the positioning blocks 11 at both ends of the positioning frame 7 move to both ends of the actuator housing, so that the two ends of the side wall of the housing can be clamped subsequently, providing better stability and rigidity to the housing, and reducing the vibration and deformation of the workpiece during processing. Then, the motor 5 is started to drive the first double-headed screw rod 4 to move the two positioning frames 7 closer to each other until the outer wall of the clamping plate 14 on one side of the positioning block 11 contacts the side wall of the actuator housing. At this time, the positioning frame 7 is continuously driven, so that the clamping plate 14 presses the first spring 15 on one side to keep fixed, and at the same time, a large clamping force that does not damage the housing is generated between the clamping plate 14 and the actuator housing, so that the actuator housing can be firmly fixed between the two positioning frames 7, ensuring the stability during subsequent processing and preventing the housing from shaking and causing the processing position to shift.

[0030] Furthermore, an air passage 16 is provided at one end of the first piston chamber 12. A second piston chamber 17 is provided at one end of the air passage 16. A plurality of guide grooves 20 are provided around the positioning block 11 close to the second piston chamber 17. A second spring 18 is installed on the inner wall of the second piston chamber 17. One end side wall of the second spring 18 is provided with a second piston rod 19 that is piston-connected to the inner wall of the second piston chamber 17. One end of the second piston rod 19 is fixedly connected to a positioning plate 21. A plurality of guide rods 22 that are slidably connected to the inner wall of the guide groove 20 are installed above the positioning plate 21.

[0031] It should be noted that: When the outer wall of the clamping plate 14 on one side of the positioning block 11 contacts the side wall of the actuator housing, at this time, while continuously driving the positioning frame 7, the clamping plate 14 remains stationary, and at the same time, the positioning block 11 continues to move, so that the first piston rod 13 at one end of the clamping plate 14 slides and presses toward the air passage 16, generating a large pressure force that forces the second piston rod 19 on the inner wall of the second piston chamber 17 at the other end of the air passage 16 to be squeezed and slide downward, driving the lower positioning plate 21 to slide tightly against the inner wall of the lower end of the actuator housing, fixing the actuator housing downward on the bottom inner wall of the processing chamber 2, further fixing the actuator housing in another direction, improving the fixing strength and thus reducing the probability of the housing shifting during processing.

[0032] The working principle of this pneumatic valve actuator housing processing equipment:

[0033] Place the actuator housing in the processing chamber 2. Rotate the knob 10 according to the width of the actuator housing so that the positioning blocks 11 at both ends of the positioning frame 7 move to both ends of the actuator housing. Start the motor 5 to drive the first double-headed screw 4 to move the two positioning frames 7 closer to each other until the outer wall of the clamping plate 14 on one side of the positioning block 11 contacts the side wall of the actuator housing. At this time, continue to drive the positioning frame 7 so that the clamping plate 14 presses against the first spring 15 to maintain fixation. At the same time, the positioning block 11 continues to move, causing the first piston rod 13 at one end of the clamping plate 14 to slide and press against the airway 16. A large pressing force is generated to force the second piston rod 19 on the inner wall of the second piston chamber 17 at the other end of the airway 16 to slide downward, driving the lower positioning plate 21 to slide down and tightly abut against the lower inner wall of the actuator housing, fixing the actuator housing downward on the bottom inner wall of the processing chamber 2. Further fix the actuator housing in another direction to improve the fixing strength and thereby reduce the probability of the housing shifting during processing. After that, the device body 1 can be driven through the control panel to work and stably process the actuator housing inside the processing chamber 2.

[0034] It should be noted that the specific model and specification of the motor need to be selected and determined according to the actual specifications of the device. The specific selection calculation method adopts the existing technology in this field, so it will not be elaborated in detail.

[0035] The above are only the preferred embodiments of the present invention and are not used to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
