[0041] As Figure 3 and Figure 7 shown, as a specific technical solution, the driving mechanism 6 includes a third gear 601 and a motor 605; the motor 605 is fixedly installed inside the housing 1, the output shaft end of the motor 605 is fixedly sleeved with the third gear 601, and the top and bottom of the third gear 601 are respectively meshed with a third rack 602 and a fourth rack 603; guide grooves are respectively provided in the third rack 602 and the fourth rack 603, and the guide grooves are in clearance fit connection with guide posts 604, and the guide posts 604 are fixedly installed inside the housing 1; the third rack 602 and the fourth rack 603 are respectively fixedly connected to the top ends of the fixed sleeves 402 of the two jaws 4.

[0042] As Figure 7 shown, a first connecting frame 606 is fixedly installed on the third rack 602, a second connecting frame 607 is fixedly connected to the fourth rack 603, and the first connecting frame 606 and the second connecting frame 607 are fixedly connected to the fixed sleeves 402 of the two jaws 4.

[0043] The motor 605 drives the third gear 601 to rotate. Through the meshing transmission between the third gear 601 and the third rack 602, and the meshing transmission between the third gear 601 and the fourth rack 603, and in cooperation with the guiding action provided between the guide grooves and the guide posts 604, the third rack 602 and the fourth rack 603 drive the two jaws 4 to move in opposite directions to clamp or release the workpiece.

[0044] As Figure 8As shown, as a specific technical solution, the movable sleeve 401 is slidably sleeved on the outer wall of the fixed sleeve 402. A transmission component is arranged between the movable sleeve 401 and the inside of the fixed sleeve 402. The input end of the transmission component is connected with a pressure rod 403. The pressure rod 403 penetrates through a guide hole 405 opened at the top of the fixed sleeve 402, and the top end of the pressure rod 403 abuts against the inner wall of the top of the housing 1.

[0045] As Figure 4 shown, as a specific technical solution, downwardly inclined walking slopes 101 are arranged on opposite sides of the top of the housing 1; the top end of the pressure rod 403 is spherical.

[0046] As Figures 8 - 10 shown, as a specific technical solution, the transmission component includes a first rack 404 and a second rack 409; the bottom end of the first rack 404 is fixedly connected with the inner wall of the bottom end of the movable sleeve 401. The top end of the first rack 404 extends into the bottom port of the fixed sleeve 402. The first rack 404 is meshed with a first gear 410. The first gear 410 is rotatably installed in the bottom port of the fixed sleeve 402. A second gear 411 is coaxially and fixedly installed on the first gear 410. A second rack 409 is meshed with the side of the second gear 411 away from the first rack 404. The top end of the second rack 409 is fixedly connected with the bottom end of the pressure rod 403; the diameter of the first gear 410 is larger than the diameter of the second gear 411.

[0047] As Figure 9 shown, as a specific technical solution, a fixed block 406 is fixedly installed on the pressure rod 403, and the fixed block 406 is slidably installed in the fixed sleeve 402. The top of the fixed block 406 is elastically connected with the inner wall of the top end of the fixed sleeve 402 through a spring 407. A stop post 408 is arranged on the top of the fixed block 406, and the top end of the stop post 408 is fixedly connected with the inner wall of the top end of the fixed sleeve 402.

[0048] As Figures 3 - 4 shown, at this time, the two jaws 4 are in an open state. When clamping a workpiece, the workpiece is placed between the two jaws 4. The driving mechanism 6 drives the two jaws 4 to approach each other, and the movable sleeve 401 of the two jaws 4 is used to clamp the workpiece; after clamping the workpiece, the industrial robot drives the workpiece to the position where it needs to be placed, and the driving mechanism 6 drives the two jaws 4 to move away from each other to release and drop the workpiece; after dropping the workpiece, the two jaws 4 return to the open state as Figures 3 - 4 shown; in this state, the movable sleeve 401 of the jaw 4 is located below the housing 1. At the same time, the pressure rod 403 on the jaw 4 is located on one side of the walking slope 101, and there is a gap between the jaw 4 and the inner side wall of the housing 1, so that the two jaws 4 have an activity space to continue to open and move away.

[0049] With the gripper 4 in the open state as shown in Figures 3 - 4 , the driving mechanism 6 drives the gripper 4 to continue to open. The gripper 4 approaches the inner wall of the housing 1, and the pressure rod 403 moves from the inner wall of the top of the housing 1 to the walking inclined surface 101. Through the extrusion of the walking inclined surface 101, the pressure rod 403 moves into the fixed sleeve 402 until the annular shell 505 on the movable sleeve 401 fits against the inner wall of the housing 1. During the above process, the pressure rod 403 drives the second rack 409 to move downward. Through the meshing transmission between the second rack 409 and the second gear 411, the second gear 411 and the first gear 410 rotate together. Then, through the meshing transmission between the first gear 410 and the first rack 404, the movable sleeve 401 moves upward. Since the diameter of the first gear 410 is larger than that of the second gear 411, it is ensured that the movable sleeve 401 is received into the housing 1; the design that the movable sleeve 401 can be received is realized. In the non-working state, it can be received for protection.

[0050] Meanwhile, during the process of receiving the movable sleeve 401, the pressure rod 403 drives the fixed block 406 to move downward together, and at the same time stretches the spring 407; when the entire clamping device resumes work, the driving mechanism 6 drives the gripper 4 to return to the state as shown in Figures 3 - 4 . The pressure rod 403 is separated from the walking inclined surface 101, and the top of the pressure rod 403 abuts against the inner wall of the top of the housing 1 again. Through the elastic force of the spring 407, the fixed block 406 and the pressure rod 403 move upward together. The pressure rod 403 drives the second rack 409 to move upward. Through the meshing transmission between the second rack 409 and the second gear 411, the second gear 411 and the first gear 410 rotate together. Through the meshing transmission between the first gear 410 and the first rack 404, the first rack 404 and the movable sleeve 401 move downward together, so that the movable sleeve 401 extends out from the bottom of the housing 1, and the fixed block 406 fits against the stop post 408 and is blocked by the stop post 408.

[0051] As shown in Figure 2 and Figure 5 , as a specific technical solution, the plugging assembly 7 includes a sleeve plate 701 fixedly installed on the bottom port of the housing 1; a chute 702 is formed on the sleeve plate 701, and a movable plate 703 is slidably installed in the chute 702, and a telescopic rod 704 is fixedly installed inside the chute 702, and the telescopic rod 704 is fixedly connected to the movable plate 703. The telescopic rod 704 adopts an electric push rod.

[0052] The plugging assembly 7 is used to control the opening and closing of the bottom port of the housing 1; in the working state, the bottom port of the housing 1 is in the open state, that is, a gap is formed between the two movable plates 703, as shown in Figure 5As shown; in the non-working state, the movable sleeve 401 is received into the housing 1. After being received, the telescopic rod 704 extends, driving the movable plate 703 to slide in the chute 702, so that the movable plate 703 extends out of the chute 702 until the movable plates 703 of the two plugging assemblies 7 are in contact with each other to achieve plugging; before the movable sleeve 401 extends out from the bottom end of the housing 1 again, by contracting the telescopic rod 704, the movable plate 703 is driven to be received into the chute 702 and restored to as Figure 5 shown. After the two movable plates 703 form a distance, the movable sleeve 401 extends out and can be restored to the working state.

[0053] Through the above design, the entire clamping device can be switched between the working state and the non-working state; in the working state, the workpiece can be normally clamped, and in the non-working state, the clamping jaw 4 can be received, and at the same time, the bottom port of the housing 1 is plugged to provide closed protection for the clamping jaw 4, avoiding the attachment of dust and dirt on the clamping jaw 4 in the non-working state, and preventing dust and dirt from entering the housing 1.

[0054] As Figure 2 shown, as a specific technical solution, the filtering and blowing assembly 3 includes a frame body 301; one side of the frame body 301 is communicated with the housing 1, a plurality of blowers 303 are fixedly installed in the frame body 301, a filter screen 302 is arranged on the side of the frame body 301 away from the housing 1, and a filter 304 is arranged on the side of the frame body 301 connected to the housing 1. Among them, the filter 304 adopts a high-efficiency filter 304.

[0055] When the entire clamping device is in the working state, the filtering and blowing assembly 3 can blow clean air flow into the housing 1, so that a positive pressure is formed at the bottom port of the housing 1, which can prevent dust and dirt from entering the housing 1 through the bottom port of the housing 1, thereby avoiding affecting the components inside the housing 1 and ensuring internal cleanliness.

[0056] The specific operation of the filtering and blowing assembly 3 is as follows. The blower 303 generates a blowing air flow, so that the outside air is filtered by the filter screen 302 and then filtered again by the filter 304 and enters the housing 1, thereby ensuring that clean air flow is blown into the housing 1.

[0057] As Figure 10 shown, as a specific technical solution, the flushing mechanism 5 includes an annular shell 505; the annular shell 505 is sleeved on the movable sleeve 401, and a collar 508 is fixedly installed on the top of the annular shell 505. The inner circle of the collar 508 is connected with the outer wall of the movable sleeve 401 with a clearance fit. A plurality of flushing nozzles 509 are evenly installed around the inner circle of the annular shell 505, and the annular shell 505 is connected with an infusion pipe fitting.

[0058] As Figure 3 andFigure 6 As shown, as a specific technical solution, the infusion pipe fitting includes a connecting pipe 501 fixedly installed on the outer wall of the housing 1. One end of the connecting pipe 501 is fixedly communicated with a three-way pipe 503, and the other end of the connecting pipe 501 is fixedly communicated with a spiral hose 504. One end of the spiral hose 504 is fixedly connected to the annular shell 505, and the spiral hose 504 is communicated with the annular shell 505. A storage cylinder 502 is fixedly installed on both sides of the housing 1, and one side of the spiral hose 504 is embedded in the storage cylinder 502. The connection part of the spiral hose 504 and the connecting pipe 501 is fixedly connected to the storage cylinder 502. Among them, the three-way pipe 503 is externally connected to a liquid supply device.

[0059] As Figure 3 , Figure 4 and Figure 6 As shown, as a specific technical solution, a guide sleeve 506 is fixedly installed on the back of the annular shell 505; a horizontally arranged guide rod 507 is fixedly installed inside the housing 1, and the guide rod 507 is slidably sleeved with the guide sleeve 506.

[0060] When the clamping device switches from the working state to the non-working state, the movable sleeve 401 moves into the housing 1 for storage. The movable sleeve 401 moves upward with respect to the annular shell 505. At the same time, the movable sleeve 401 approaches the inner side wall of the housing 1. The movable sleeve 401 drives the annular shell 505 to move horizontally together, and is guided by the guide rod 507 and the guide sleeve 506, so that the movable sleeve 401 only moves upward with respect to the annular shell 505. When dirt adheres to the surface of the movable sleeve 401 and needs to be cleaned, the liquid supply device injects cleaning liquid into the three-way pipe 503. The cleaning liquid is transported through the three-way pipe 503, the connecting pipe 501, and the spiral hose 504, enters the annular shell 505, and then sprays out from the flushing nozzle 509 to flush and clean the peripheral surface of the movable sleeve 401 to ensure the cleanliness of the surface.

[0061] Through the above, the whole device has the function of cleaning the clamping jaw 4. After cleaning the clamping jaw 4, blowing is provided by the filtering and blowing assembly 3 to achieve air drying. After air drying, the bottom port of the housing 1 is closed.

[0062] Among them, through the design of the spiral hose 504, it is suitable for the left and right movement of the clamping jaw 4, ensuring that the flushing mechanism 5 continues to perform flushing operations when the clamping jaw 4 moves left and right.

[0063] The present invention is not limited to the above embodiments. No matter what changes are made in its shape or structure, they all fall within the protection scope of the present invention. The protection scope of the present invention is defined by the appended claims.
