[0058] When in use, the collar 421 can rotate on the side wall of the screw rod 40 . When the screw rod 40 descends, the collar 421 is driven to descend, and the collar 421 drives the pull rope 422 to move.

[0059] Furthermore, the adjusting part 43 includes a rack 431 at one end of the pull rope 422, the rack 431 is slidably connected to the second base 14, a seventh spring 432 is provided on the rack 431, a top tube 433 is provided on the side wall of the slide rod 191, a threaded tube 434 is provided on the side wall of the top tube 433, and the outer wall of the threaded tube 434 is engaged with the rack 431.

[0060] It should be noted that, through the setting of the guide hole 322, the pull rope 422 can pull the rack 431 horizontally, and the threaded tube 434 can rotate on the side wall of the slide rod 191. When the threaded tube 434 rotates, it can drive the two top tubes 433 to approach each other, releasing the support for the slider 192. Driven by the fifth spring 202, the two sliders 192 approach each other, increasing the elongation distance of the fourth spring 194, thereby increasing the clamping force of the clamp 18 on the valve body, and making the clamping of the valve body more stable.

[0061] During use, when the ring 421 descends, it can drive the pull rope 422, and the pull rope 422 drives the rack 431 to move, and the rack 431 drives the threaded tube 434 to rotate, so that the position of the top tube 433 changes, changing the support position of the slider 192, and the rack 431 drives the seventh spring 432 to contract. When the ring 421 rises, the seventh spring 432 recovers and drives the rack 431 to move in the opposite direction, so that the threaded tube 434 rotates in the opposite direction, and the top tube 433 returns to its initial position.

[0062] Working principle: When the valve body needs to be sprayed, first, the worker selects the clamp 18 according to the valve body, the worker presses the screw rod 40, the screw rod 40 drives the lifting plate 164 to descend, the lifting plate 164 drives the third spring 163 to contract, the lifting plate 164 extrudes the fixed rod 161, so that the locking rod 155 enters the inside of the first base 13, the locking rod 155 drives the second spring 154 to contract, at this time, the second base 14 with the clamp 18 is inserted between the first base 13 and the sliding groove 12, the pressing on the screw rod 40 is removed, the second spring 154 and the third spring 163 recover, the second spring 154 drives the locking rod 155 to insert into the inside of the second base 14, the locking of the second base 14 is completed, the third spring 163 recovers and drives the lifting plate 164 to return to the initial position, the lifting plate 164 drives the screw rod 40 to rise to the initial position, the pull rope 422 is connected with the thimble 421, and the air pipe 195 on the air bag 193 is connected with the air pump.

[0063] Because the sizes of the valve bodies are different, in order to ensure the stability of the clamping of the clamp 18 on the valve body, the worker can drive the screw rod 40, the screw rod 40 descends and drives the thimble 421 to descend, the thimble 421 drives the pull rope 422, the pull rope 422 drives the rack 431, the rack 431 drives the threaded pipe 434 to rotate, when the threaded pipe 434 rotates, the two top pipes 433 approach each other, the support on the sliding block 192 is removed, the sixth spring 323 drives the two sliding blocks 192 to approach each other, and the clamping force of the clamp 18 on the valve body is further increased, when the screw rod 40 rises, the seventh spring 432 can drive the rack 431 to move reversely, so that the threaded pipe 434 reverses, and the sliding block 192 returns to the initial position.

[0064] The mechanical arm is controlled by the machine body 10 to move and clamp the valve body, when the machine body 10 drives the cross 11 to move to the valve body, the machine body 10 controls the air pump to fill the inside of the air bag 193 with gas, as the gas in the inside of the air bag 193 increases, the air bag 193 drives the clamp 18 to gradually open, and drives the fourth spring 194 to elongate, when the opening of the clamp 18 opens to the maximum, the mechanical arm drives the clamp 18 to approach the valve body, when the position of the clamp 18 is determined, the gas in the inside of the air bag 193 is reversely extracted, under the recovery of the fourth spring 194, the fourth spring 194 drives the air bag 193 to contract, and the fourth spring 194 drives the opening of the clamp 18 to decrease to clamp the valve body, after the valve body is placed on the workbench by the mechanical arm, the inside of the air bag 193 is filled with gas again to release the clamping on the valve body, and the valve body is sprayed by the spraying robot.

[0065] When the machine body 10 is suddenly powered off, the clamp 18 can keep clamping the valve body through the top pipe 433, the sliding block 192 and the fourth spring 194, the power-off cannot affect the clamping of the clamp 18 on the valve body, and since the gas cannot be delivered to the inside of the air bag 193 to release the clamping on the valve body, the worker can reverse the driving disc 172, the driving disc 172 drives the arc block 332 to extrude the top rod 31, the top rod 31 drives the rectangular frame 30 to move close to the inside of the T-shaped groove 22, the first section 321 on the rectangular frame 30 extrudes the second section 324 on the sliding block 192, the two sliding blocks 192 move away from each other and separate from the top pipe 433, the sliding block 192 drives the fifth spring 202 to elongate, the sliding block 192 drives the air bag 193 and the fourth spring 194 to move, so as to slow down the clamping force of the clamp 18 on the valve body, when the follower rod 171 moves to the end of the second arc-shaped groove 331, the limiting rod 344 can be inserted into the inside of the first through hole 341, so as to facilitate the worker to take down the valve body from the clamp 18.

[0066] When it is necessary to replace the four clamps 18, the worker rotates the driving disc 172 in the forward direction, so that the first arc-shaped groove 173 pulls the follower rod 171, the follower rod 171 drives the long pipe 152, the long pipe 152 drives the first spring 153 to contract, the long pipe 152 drives the locking rod 155 to move, when the limiting rod 344 on the driving disc 172 moves to the first through hole 341, the limiting rod 344 can be inserted into the inside of the first through hole 341, the driving disc 172 is locked, at this time, the four second bases 14 are released, so as to facilitate the replacement of the clamps 18 on the bases.
