[0036] See also Figures 1-6 As shown, the utility model is a size-adaptive pneumatic gripper, comprising a mounting frame 1:

[0037] The mounting frame 1 is provided with a first drive assembly 2, a second drive assembly 3, a transmission assembly 4, a clamping assembly 5 and a replacement assembly 6 respectively;

[0038] The telescopic end of the first driving component 2 is in contact with the inner side of the clamping component 5, so that the first driving component 2 drives the clamping component 5 to clamp and fix the object;

[0039] The output end of the second driving component 3 is fixedly mounted inside the transmission component 4 so that the second driving component 3 drives the transmission component 4 to operate;

[0040] The outer surface of the clamping assembly 5 is fixedly mounted to the interior of the transmission assembly 4 so that the transmission assembly 4 drives the clamping assembly 5 to rotate when the transmission assembly 4 is in operation, so that the clamping assembly 5 can adjust the direction of the object;

[0041] The outer surface of the replacement component 6 is slidably arranged inside the clamping component 5, so that the replacement component 6 can easily replace the clamping block.

[0042] During use, the first driving component 2 is started to drive the clamping component 5 that is fitted at the telescopic end to perform a clamping operation. When the clamping component 5 is in operation, it can drive the replacement component that is slidably arranged inside it to clamp and fix the object. Then the second driving component 3 is started to drive the transmission component 4 fixedly installed at the output end to rotate. When the transmission component 4 rotates, it can drive the clamping component 5 fixedly installed inside it to rotate. When the clamping component 5 rotates, it can drive the replacement component 6 that is slidably arranged inside it to rotate, so that it can adjust the angle of the object. The clamping end of the object can be replaced by the replacement component 6, thereby avoiding wear caused by long-term use.

[0043] The utility model starts the first driving component 2 to drive the clamping component 5 that is fitted at the telescopic end to perform a clamping operation. When the clamping component 5 is in operation, it can drive the replacement component that is slidably arranged inside it to clamp and fix the object. Then, the second driving component 3 is started to drive the transmission component 4 fixedly installed at the output end to rotate. When the transmission component 4 rotates, it can drive the clamping component 5 fixedly installed inside it to rotate. When the clamping component 5 rotates, it can drive the replacement component 6 that is slidably arranged inside it to rotate, so that it can adjust the angle of the object. The clamping end of the object can be replaced by the replacement component 6, and then it can be replaced after it is worn to ensure its clamping effect on the object.

[0044] In one embodiment, for the above-mentioned first drive component 2, the first drive component 2 includes a support plate 201, the bottom end of the support plate 201 is fixedly connected to the top of the mounting frame 1, the top of the support plate 201 is fixedly connected to a cylinder 202, the telescopic end of the cylinder 202 is fixedly installed with a connecting piece 203, the outer surface of the connecting piece 203 is fixedly installed with a push block 204, and the outer surface of the push block 204 is in contact with the surface of the clamping component 5.

[0045] By starting the cylinder 202, the connecting piece 203 fixedly installed at the telescopic end is driven to move up and down. When the connecting piece 203 moves, it can drive the push block 204 fixedly installed on its outer surface to move. Since the push block 204 is set in a cone shape and its outer surface fits the outer surface of the clamping component 5, when the push block 204 moves upward, it can push one end of the clamping component 5 to move outward in a circular motion, so that the other end of the clamping component 5 can move in a circular motion inward, thereby facilitating the clamping and fixing of the object.

[0046] In one embodiment, for the above-mentioned second drive component 3, the second drive component 3 includes a fixed frame 301, one side of the fixed frame 301 is fixedly installed with one side of the mounting frame 1, and a motor 302 is fixedly installed at the top of the fixed frame 301, and the output end of the motor 302 is fixedly installed with the inside of the transmission component 4.

[0047] The transmission assembly 4 fixedly mounted at the output end is driven to operate by starting the motor 302 so as to provide stable power thereto.

[0048] In one embodiment, for the above-mentioned transmission assembly 4, the transmission assembly 4 includes a first synchronous wheel 401, the interior of the first synchronous wheel 401 is fixedly installed with the output end of the motor 302, the outer surface of the first synchronous wheel 401 is driven by a synchronous belt 402, and the inner side of the synchronous belt 402 is driven by a second synchronous wheel 403, and the interior of the second synchronous wheel 403 is fixedly installed with the outer surface of the clamping assembly 5.

[0049] The first synchronous wheel 401 fixedly installed at the output end is driven to rotate by starting the motor 302. Since the outer surfaces of the first synchronous wheel 401 and the second synchronous wheel 403 are both arranged to be transmitted to the inner side of the synchronous belt 402, when the first synchronous wheel 401 rotates, it can cooperate with the synchronous belt 402 to drive the second synchronous wheel 403 to rotate, so that it can drive the clamping assembly 5 fixedly installed inside to rotate, so as to adjust the angle of the object.

[0050] In one embodiment, the clamping assembly 5 includes a connecting tube 501, the outer surface of which is fixedly mounted on the inside of the second synchronous wheel 403, and a hinge seat 502 is fixedly connected to the bottom end of the connecting tube 501. A clamping claw 503 is hingedly provided inside the hinge seat 502, and the outer surface of the clamping claw 503 is in contact with the outer surface of the push block 204.

[0051] An elastic band 504 is sleeved on the outer surface of the clamping jaw 503 , and the interior of the clamping jaw 503 is slidably arranged with the outer surface of the replacement component 6 .

[0052] When the second synchronous wheel 403 rotates, it can drive the connecting cylinder 501 fixed therein to rotate, which can drive the hinge seat 502 fixed at its bottom end to rotate. When the hinge seat 502 rotates, it can drive the clamping claw 503 hingedly arranged therein to rotate, so as to adjust the angle of the object it clamps and fixes; when the pushing block 204 moves upward with the movement of the connecting member 203, it can push one end of the clamping claw 503 fitted on its outer surface to cooperate with the hinge seat 502 to make a circular motion outward, and then the other end of the clamping claw 503 makes a circular motion inward, which makes it easier to clamp and fix the object; when the pushing block 204 moves downward, one end of the clamping claw 503 loses its driving force, and then the elastic band 504 can shrink and reset one end of the clamping claw 503, thereby resetting the other end, thereby releasing the clamping of the object.

[0053] In one embodiment, the replacement assembly 6 includes a sliding rod 601 and a connecting block 602. Both ends of the sliding rod 601 are fixedly connected to the inside of the clamping jaw 503. A slider 603 is slidably provided on the outer surface of the sliding rod 601. A spring 604 is fixedly connected to one side of the slider 603. A wedge 605 is fixedly connected to one side of the slider 603.

[0054] A wedge-shaped groove 606 is formed on one side of the connecting block 602 . The interior of the wedge-shaped groove 606 is engaged with the outer surface of the wedge block 605 . A rubber block 607 is fixedly connected to one side of the connecting block 602 .

[0055] By inserting the outer surface of the connecting block 602 into the interior of the clamping claw 503, the wedge surface set on one side can fit with one side of the wedge block 605, and as the connecting block 602 continues to move, the wedge block 605 can be pushed to move, and the slider 603 fixed to one side can be driven to move. Since the interior of the slider 603 is set to slide with the outer surface of the sliding rod 601, and one side of the slider 603 is fixedly connected to the spring 604, when the slider 603 moves, it can be moved along the direction of the sliding rod 601 and The spring 604 is compressed. When the wedge-shaped groove 606 opened on one side of the connecting block 602 moves to the side of the wedge block 605, the spring 604 can push the slider 603 to move, and drive the wedge block 605 into the inside of the wedge groove 606, thereby fixing the position of the connecting block 602. When it needs to be disassembled, the slider 603 can be pushed upward to drive the wedge block 605 out of the inside of the wedge groove 606, thereby facilitating the replacement of the rubber block 607 set on one side of the connecting block 602 to avoid wear caused by long-term use.

[0056] In one embodiment, for the clamping jaw 503 , a limiting slot 7 is provided inside the clamping jaw 503 , a limiting block 8 is slidably provided inside the limiting slot 7 , and one side of the limiting block 8 is fixedly connected to one side of the slider 603 .

[0057] When the slider 603 moves, it can drive the limiting block 8 fixedly connected to one side thereof to move along the direction of the limiting slot 7, so as to improve the stability of the slider 603 during the movement.

[0058] Through the above technical solution, 1. By starting the first driving component 2 to drive the clamping component 5 that is fitted at the telescopic end to perform a clamping operation, when the clamping component 5 is in operation, it can drive the replacement component that is slidably arranged inside it to clamp and fix the object, and then start the second driving component 3 to drive the transmission component 4 fixedly installed at the output end to rotate. When the transmission component 4 rotates, it can drive the clamping component 5 fixedly installed inside it to rotate. When the clamping component 5 rotates, it can drive the replacement component 6 that is slidably arranged inside it to rotate, so that it can adjust the angle of the object. The clamping end of the object can be replaced by the replacement component 6, and then it can be replaced after it is worn to ensure its clamping effect on the object;

[0059] 2. By inserting the outer surface of the connecting block 602 into the interior of the clamping jaw 503, the wedge surface provided on one side thereof can fit with one side of the wedge block 605. Then, as the connecting block 602 continues to move, the wedge block 605 can be pushed to move, and the slider 603 fixed to one side thereof can be driven to move. Since the interior of the slider 603 is slidably arranged with the outer surface of the sliding rod 601, and a spring 604 is fixedly connected to one side of the slider 603, when the slider 603 moves, it can be moved along the direction of the sliding rod 601. The spring 604 is compressed. When the wedge-shaped groove 606 opened on one side of the connecting block 602 moves to one side of the wedge block 605, the spring 604 can push the slider 603 to move, and drive the wedge block 605 into the inside of the wedge groove 606, thereby fixing the position of the connecting block 602. When it needs to be disassembled, the slider 603 can be pushed upward to drive the wedge block 605 out of the inside of the wedge groove 606, thereby facilitating the replacement of the rubber block 607 set on one side of the connecting block 602 to avoid wear caused by long-term use.
