Description

Technical Field

[0001] The present invention relates to the technical field of jigs, and particularly to a clamping tooling. Background Art

[0002] During the production process of products, processing is often carried out on the surface of the products. When processing, jigs are required to clamp the products to prevent displacement of the products during the processing, which may cause damage to the products.

[0003] For products with a cuboid structure, existing clamping toolings generally have clamping members in two directions. By operating the two clamping members separately, the two clamping members can move away from or close to the product to complete the clamping or release of the product. The above clamping structure makes it necessary to operate the two clamping members separately each time the product is placed or taken out, resulting in low clamping and placement efficiency of the product and high labor intensity. In addition, the clamping sequence of the two clamping members is prone to confusion, resulting in incorrect clamping of the product, thus affecting the clamping effect and having an impact on the product.

[0004] Therefore, there is an urgent need to study a clamping tooling to solve the problem that the two clamping members need to be operated separately during each process of taking and placing the product, resulting in low clamping and placement efficiency of the product and high labor intensity.

[0049] The embodiments of the present invention will be described in detail below. The examples of the embodiments are shown in the accompanying drawings, where the same or similar reference numerals represent the same or similar elements or elements with the same or similar functions from beginning to end. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention and should not be construed as a limitation to the present invention.

[0050] Such as Figures 1-6As shown in the figure, this embodiment provides a clamping tooling, which includes a workbench 1, a first clamping component 2, a second clamping component 3, and an opening and closing component 4. Among them, the workbench 1 is provided with a working position for placing the workpiece 100; the first clamping component 2 can clamp or release the workpiece 100 in the first direction X; the second clamping component 3 can clamp or release the workpiece 100 in the second direction Y; the opening and closing component 4 includes a cam 41, and the cam 41 can rotate between an open position and a fixed position. When the cam 41 is in the open position, both the first clamping component 2 and the second clamping component 3 are in a released state, that is, both the first clamping component 2 and the second clamping component 3 release the workpiece 100; when the cam 41 is in the fixed position, both the first clamping component 2 and the second clamping component 3 are in a clamped state, that is, both the first clamping component 2 and the second clamping component 3 clamp the workpiece 100; the first direction X is perpendicular to the second direction Y.

[0051] The clamping tooling can drive the first clamping component 2 and the second clamping component 3 to release or clamp the workpiece 100 by the rotation of the cam 41 in the opening and closing component 4 between the open position and the fixed position. The operation process only needs to rotate the cam 41 by a certain angle to realize the control of the first clamping component 2 and the second clamping component 3. Only one operation is required to complete the clamping or release of the workpiece 100 in two directions, which improves the working efficiency of placing and taking out the workpiece 100 and reduces the labor intensity.

[0052] Optionally, the workbench 1 is provided with a first positioning protrusion 15 and a second positioning protrusion 16, and the workpiece 100 is provided with a first positioning hole 101 and a second positioning hole 102. The first positioning protrusion 15 can be inserted into the first positioning hole 101, and the second positioning protrusion 16 can be inserted into the second positioning hole 102. The first positioning protrusion 15 is strip-shaped, the second positioning protrusion 16 is cylindrical, the first positioning hole 101 and the first positioning protrusion 15 are matched in shape and are strip-shaped, and the second positioning hole 102 and the second positioning protrusion 16 are matched in shape and are round holes. The above settings can play an anti-fooling effect.

[0053] In addition, three support members are provided on the bottom surface of the working position, two of which are located at one end of the working position and one is located at the other end of the working position. The workpiece 100 is placed on the three support members.

[0054] In this embodiment, the workbench 1 is provided with a first stopper 11, and the first clamping assembly 2 includes a first clamping member 21, which is slidably disposed on the workbench 1 along the first direction X and can approach or move away from the first stopper 11. The workbench 1 is provided with a second stopper 12, and the second clamping assembly 3 includes a second clamping member 31, which is slidably disposed on the workbench 1 along the second direction Y and can approach or move away from the second stopper 12. This arrangement can clamp the workpiece 100, and is convenient for providing a larger clamping surface on the first clamping member 21 and the second clamping member 31, so as to avoid generating a large pressure on the workpiece 100.

[0055] The opening and closing assembly 4 includes a first lever 42, which is rotatably arranged on the workbench 1 via a first rotating shaft 420. By moving one end of the first lever 42, the other end of the first lever 42 can drive the first clamping member 21 away from the first stopper 11. The arrangement of the first lever 42 leads out the driving end that drives the first clamping member 21, thereby preventing the power member from directly acting on the first clamping member 21, and facilitating the layout and optimization of the power member.

[0056] The opening and closing assembly 4 includes a second lever 43, which is rotatably arranged on the workbench 1 via a second rotating shaft 430. By moving one end of the second lever 43, the other end of the second lever 43 can drive the second clamping member 31 away from the second stopper 12. The second lever 43 is arranged to lead out the driving end that drives the second clamping member 31, thereby preventing the power member from directly acting on the second clamping member 31, and facilitating the layout and optimization of the power member.

[0057] The first clamping assembly 2 includes a first elastic member 22, which is disposed between the first clamping member 21 and the workbench 1, and is used to bring the first clamping member 21 close to the first stopper 11. The second clamping assembly 3 includes a second elastic member 32, which is disposed between the second clamping member 31 and the workbench 1, and is used to bring the second clamping member 31 close to the second stopper 12. The arrangement of the first elastic member 22 and the second elastic member 32 makes it easy to control the clamping force of the workpiece 100, and does not cause the workpiece 100 to be damaged due to excessive clamping force.

[0058] When clamping the workpiece 100, once there is sliding friction between the clamping part and the workpiece 100, it will affect the clamping surface of the workpiece 100. Even if the clamping surface of the workpiece 100 is scratched, it will be judged as a defective product, resulting in a reduction in the yield rate of the workpiece 100. Since the position where the workpiece 100 is placed is generally larger than the corresponding dimensions of the workpiece 100 in both the width and length directions, during the clamping process, after the first clamping member 21 and the first stop portion 11 first clamp the workpiece 100, during the clamping process of the second clamping member 31, the workpiece 100 will have a certain displacement in the second direction Y. At this time, friction will occur between the workpiece 100 and the first clamping member 21 and the first stop portion 11. Or in another case, during the clamping process, after the second clamping member 31 and the second stop portion 12 first clamp the workpiece 100, during the clamping process of the first clamping member 21, the workpiece 100 will have a certain displacement in the first direction X. At this time, friction will occur between the workpiece 100 and the second clamping member 31 and the second stop portion 12. The best working state is to complete the clamping action of the workpiece 100 in both directions simultaneously, but this is an ideal state and cannot be achieved in reality.

[0059] Therefore, in this embodiment, when designing the clamping tooling, it is necessary to distinguish the forces of the two clamping members in the tooling. Specifically, the first clamping assembly 2 includes a first elastic member 22, and the first elastic member 22 is disposed between the first clamping member 21 and the workbench 1 for making the first clamping member 21 approach the first stop portion 11. The second clamping assembly 3 includes a second elastic member 32, and the second elastic member 32 is disposed between the second clamping member 31 and the workbench 1 for making the second clamping member 31 approach the second stop portion 12. The elastic force provided by the second elastic member 32 is less than the elastic force provided by the first elastic member 22. With the above settings, when installing the workpiece 100, the second clamping assembly 3 can be operated first, so that the second clamping member 31 and the second stop portion 12 clamp the workpiece 100, and the workpiece 100 is first moved in place in the second direction Y. Then, the first clamping assembly 2 is operated to make the first clamping member 21 and the first stop portion 11 clamp the workpiece 100. During this process, the workpiece 100 will move in place in the first direction X. Since the elastic force provided by the second elastic member 32 is small, during the movement process, the friction between the workpiece 100 and the second clamping member 31 is small, and the influence generated is small. Of course, in other embodiments, the two opposite faces of the workpiece 100 without surface finish requirements can be aligned with the second clamping member 31.

[0060] During the operation, it is inevitable that the operator will get confused. After the product is placed, the operator first operates the first clamping assembly 2, causing the first clamping member 21 and the first stop portion 11 to clamp the workpiece 100. Then, the operator operates the second clamping member 31. At this time, due to the relatively large force of the first elastic member 22, when the workpiece 100 moves along the second direction Y during the clamping process of the second clamping member 31, a relatively large frictional force will occur between the workpiece 100 and the first clamping member 21 and the first stop portion 11, thereby causing relatively serious wear to the workpiece 100.

[0061] To this end, in this embodiment, optionally, the cam 41 includes a rotating shaft 410 and a first approaching portion 411, a first departing portion 412, a second approaching portion 413, and a second departing portion 414 that are sequentially arranged around the circumference of the rotating shaft 410. When the cam 41 is in the open position, the first departing portion 412 drives the first clamping assembly 2 to release the workpiece 100, and the second departing portion 414 drives the second clamping assembly 3 to release the workpiece 100. When the cam 41 is in the fixed position, the first approaching portion 411 drives the first clamping assembly 2 to clamp the workpiece 100, and the second approaching portion 413 drives the second clamping assembly 3 to clamp the workpiece 100. The arc radius between the first approaching portion 411 and the first departing portion 412 is greater than the arc radius between the second approaching portion 413 and the second departing portion 414. With the above arrangement, when the cam 41 rotates from the open position to the fixed position, the second clamping assembly 3 acts first, and the first clamping assembly 2 acts later. Among them, the arc radius between the first approaching portion 411 and the first departing portion 412 is 4 mm - 5 mm, and the arc radius between the second approaching portion 413 and the second departing portion 414 is 1 mm - 1.5 mm.

[0062] Specifically, when the cam 41 is in the open position, the first departing portion 412 abuts against the side surface of the other end of the first lever 42, the first clamping member 21 moves away from the workpiece 100, the second departing portion 414 abuts against the side surface of the other end of the second lever 43, and the second clamping member 31 moves away from the workpiece 100. When the cam 41 is in the fixed position, when the cam 41 is in the fixed position, the first approaching portion 411 abuts against the side surface of the other end of the first lever 42, and the first clamping member 21 clamps the workpiece 100 under the action of the first elastic member 22. The second approaching portion 413 abuts against the side surface of the other end of the second lever 43, and the second clamping member 31 clamps the workpiece 100 under the action of the second elastic member 32.

[0063] Of course, in other embodiments, the connection relationship between the cam 41 and the lever can also be that two arc-shaped chutes are provided on the cam 41, the radii of the two arc-shaped chutes are different, and two pin shafts are respectively provided on the first lever 42 and the second lever 43, and the two pin shafts are respectively inserted into the two arc-shaped chutes.

[0064] The first lever 42 is provided with an avoidance groove 422 , and the second lever 43 passes through the avoidance groove 422 . This arrangement reduces the overall thickness of the first lever 42 and the second lever 43 .

[0065] Regarding the connection relationship between the first lever 42 and the first clamping member 21, in this embodiment, a first toggle pin 421 is provided at one end of the first lever 42, and the first clamping member 21 is provided with a first toggle groove 211. The first toggle pin 421 is partially located in the first toggle groove 211 and can abut against the groove wall of the first toggle groove 211. The first toggle groove 211 can be an arc groove or a square groove, preferably a square groove. The setting of the square groove can adapt to the movement trajectory of the first toggle pin 421 on the one hand; on the other hand, it can also reduce the mass of the first clamping member 21 and reduce the cost.

[0066] Regarding the connection relationship between the second lever 43 and the second clamping member 31, in this embodiment, a second toggle pin 431 is provided at one end of the second lever 43, and the second clamping member 31 is provided with a second toggle groove 311. The second toggle pin 431 is partially located in the second toggle groove 311 and can abut against the groove wall of the second toggle groove 311. The second toggle groove 311 can be an arc groove or a square groove, preferably a square groove. The setting of the square groove can adapt to the movement trajectory of the second toggle pin 431 on the one hand; on the other hand, it can also reduce the mass of the second clamping member 31 and reduce the cost.

[0067] Of course, in other embodiments, the connection relationship between the first lever 42 and the first clamping member 21 can be other ways. For example, the first lever 42 is provided with a slide groove extending along the length direction of the first lever 42, and the first clamping member 21 is provided with a fixing column, which is inserted into the slide groove. The connection method between the second lever 43 and the second clamping member 31 can refer to the connection method between the first lever 42 and the first clamping member 21. The above-mentioned contents are only used as examples. In other embodiments, as long as there is no motion interference after the two are connected, it is not limited to this.

[0068] In this embodiment, the workbench 1 is provided with a first slide groove 13, the first clamping member 21 is slidably arranged in the first slide groove 13, and the first cover plate 23 is arranged on the workbench 1, and covers the notch of the first slide groove 13. The separate arrangement of the first cover plate 23 and the workbench 1, on the one hand, improves the production and installation efficiency, and on the other hand, the first cover plate 23 and the first slide groove 13 form a sliding channel, so that the sliding space of the first clamping member 21 is protected to avoid the jam of debris, which is conducive to smooth sliding. Similarly, the workbench 1 is provided with a second slide groove 14, the second clamping member 31 is slidably arranged in the second slide groove 14, and the second cover plate 33 is arranged on the workbench 1, and covers the notch of the second slide groove 14.

[0069] In this embodiment, the workbench 1 is provided with a first through hole and a second through hole. The first through hole is arranged in the first sliding groove 13 and communicates with the back surface of the workbench 1. The second through hole is arranged in the second sliding groove 14 and communicates with the back surface of the workbench 1. The first toggle pin 421 and the second toggle pin 431 respectively pass through the first through hole and the second through hole and are inserted into the first toggle groove 211 and the second toggle groove 311. Both the first lever 42 and the second lever 43 are located on the back surface of the workbench 1. The above arrangement makes the tabletop structure of the workbench 1 simple and convenient to operate.

[0070] Optionally, the opening and closing assembly 4 includes a handle 45. The handle 45 is arranged on the rotating shaft 410 of the cam 41 and is used to toggle the cam 41 to rotate between the open position and the fixed position. The cam 41 includes a wheel body and a rotating shaft 410. Among them, the first approaching portion 411, the first departing portion 412, the second approaching portion 413, and the second departing portion 414 are all located on the outer side surface of the wheel body. The arrangement of the handle 45 is convenient for holding by hand and improves the convenience of operation.

[0071] The workbench 1 is provided with a limiting groove 19, and the handle 45 is provided with a limiting protrusion 451. The limiting protrusion 451 is inserted into the limiting groove 19. In the state where the cam 41 is in the open position, the limiting protrusion 451 abuts against the side wall at one end of the limiting groove 19. In the state where the cam 41 is in the fixed position, the limiting protrusion 451 abuts against the side wall at the other end of the limiting groove 19. One end of the handle 45 is connected to the rotating shaft 410.

[0072] To improve the degree of automation, in this embodiment, the opening and closing assembly 4 includes a driving assembly 44. The driving assembly 44 is arranged on the workbench 1 and is used to drive the cam 41 to rotate. Specifically, the driving assembly 44 includes a driving member 441, a rack 442, and a gear 443. The driving member 441 is arranged on the workbench 1. The driving rack 442 is slidably arranged on the workbench 1 along the second direction Y and is in transmission connection with the output end of the driving member 441. The gear 443 is arranged at the input end of the cam 41 and meshes with the rack 442. The workbench 1 is provided with a slide rail, and a slider is fixed on the rack 442. The slider is slidably arranged on the slide rail. The driving member 441 includes a telescopic cylinder. The driving assembly 44 further includes a first limiting member 444 and a second limiting member 445. Both the first limiting member 444 and the second limiting member 445 are arranged on the workbench 1. The first limiting member 444 is used to limit the extended extreme position of the rack 442, and the second limiting member 445 is used to limit the retracted extreme position of the rack 442.

[0073] Among them, the driving assembly 44 further includes a first limiting block 446 and a second limiting block 447. The first limiting member 444 includes a first limiting screw, and the second limiting member 445 includes a second limiting screw. Both the first limiting block 446 and the second limiting block 447 are screwed to the workbench 1. The first limiting block 446 is provided with a first limiting screw hole, and the second limiting block 447 is provided with a second limiting screw hole. The first limiting wheel screw is screwed into the first limiting screw hole, and the second limiting screw is screwed into the second limiting screw hole. The first limiting screw and the second limiting screw are respectively used to define two extreme positions of the rack 442. Among them, the nuts of the first limiting screw and the second limiting screw are arranged oppositely and are respectively used to limit two extreme positions of the rack 442.
