[0027] The present invention will be further described in detail below with reference to the accompanying drawings.
[0028] Example 1, Reference Figures 1-4 A pneumatic downward clamp includes a clamp body 1. A first interface 3 is provided on the right side of the surface of the clamp body 1. A filter shell 5 is attached to the surface of the first interface 3. A filter plate 10 is bolted to the inner cavity of the filter shell 5. A push rod 8 is movably connected to the center of the top of the filter shell 5. A sliding plate 12 is bolted to the bottom of the push rod 8. A cleaning brush 11 is bolted to one side of the sliding plate 12. Grooves 2 are provided on the right sides of both ends of the clamp body 1.
[0029] Furthermore, limit blocks 6 are welded to both sides of the top of the filter housing 5. Limit pins 7 are inserted into the inner cavity of the limit blocks 6. The inner side of the limit blocks 6 is attached to the outer side of the push rod 8. The limit blocks 6 and the limit pins 7 facilitate the limiting and fixing of the push rod 8.
[0030] Furthermore, a first mounting block is welded to the bottom of both sides of the push rod 8, and a first mounting bolt is provided on the surface of the first mounting block. The first mounting block and the first mounting bolt facilitate the disassembly and cleaning of the cleaning brush 11, effectively removing the lint generated on the surface of the cleaning brush 11 during cleaning, and preventing the lint from being adsorbed onto the surface of the filter plate 10 again.
[0031] Furthermore, a second mounting block is welded to both sides of the filter plate 10, and a second mounting bolt is provided on the surface of the second mounting block. The filter plate 10 can be easily disassembled and replaced through the second mounting block and the second mounting bolt.
[0032] Brief description of usage: The filter plate 10 facilitates air filtration, effectively removing dust, lint, and other impurities from the air. When the filter plate 10 is used for a long time, its surface easily accumulates lint and other impurities. The user removes the limit pin 7, then presses and moves the lever 8 downwards. The lever 8 moves the sliding plate 12 downwards, which in turn moves the cleaning brush 11 and spring 13 downwards. The movement of the cleaning brush 11 cleans the dust accumulated on the surface of the filter plate 10, preventing lint and other impurities from accumulating on the surface of the filter plate 10, clogging the filter pores, and affecting air circulation.
[0033] Example 2, Reference Figures 2-4 The pneumatic downward clamp includes a sliding plate 12 with a spring 13 welded to the bottom. The bottom of the spring 13 is welded to the inner wall of the filter shell 5. The spring 13 can effectively use its own reset elasticity to push the sliding plate 12 to reset and move, which can speed up the reset time of the cleaning brush 11 and reduce the pulling force of the staff.
[0034] Furthermore, slide rails 14 are welded to both sides of the inner cavity of the filter housing 5, and both sides of the sliding plate 12 are slidably connected to the inner cavity of the slide rails 14. The slide rails 14 improve the stability of the sliding of the sliding plate 12.
[0035] Furthermore, a through-hole 9 is provided on the left side of the inner cavity of the filter housing 5, and the surface of the through-hole 9 is in contact with the surface of the first interface 3. A second interface 4 is provided on the right side of the inner cavity of the filter housing 5. Through the through-hole 9, the first interface 3 and the second interface 4, air can be transported.
[0036] Brief description of usage: First, the user removes the sealing plug on the surface of the second interface 4. Then, the user connects the piping to the second interface 4. Through the piping, air is delivered into the inner cavity of the filter housing 5 and passes through the filter plate 10, facilitating air filtration and effectively removing dust, lint, and other impurities. The filtered air then enters the inner cavity of the clamp body 1 through the port 9 and the first interface 3. At this point, the air acts as a power source, driving the clamping elements via a pneumatic transmission system to clamp the workpiece. The user can then process the workpiece. When the filter plate 10 is used for a long time, its surface easily accumulates lint and other impurities. The user removes the limit pin 7 and then presses the lever 8 to... The button 8 moves downward, causing the sliding plate 12 to move downward. The sliding plate 12 then moves the cleaning brush 11 and spring 13 downward. The cleaning brush 11 cleans the dust adsorbed on the surface of the filter plate 10, preventing lint and other impurities from adsorbing on the surface of the filter plate 10 and clogging the filter pores, thus affecting air circulation. Then, the user releases the button 8, and the limiting pressure of the spring 13 is released. The spring 13 automatically resets, pushing the sliding plate 12 to reset and move. The sliding plate 12 then moves the cleaning brush 11 to reset and move, cleaning the surface of the filter plate 10 again, thus improving the cleaning efficiency of the filter plate 10.
