Description

Technical Field

[0001] This application relates to the field of mechanical manufacturing equipment technology, and in particular to a clamping device. Background Technology

[0002] Currently, the clamping devices used for positioning and clamping parts mostly rely on electrical components. However, in the process of using electrical components to achieve clamping, due to the limited functionality of the electrical components, multiple electronic components are required to cooperate to achieve multi-directional movement, which is complicated and costly and cannot meet the current production needs. Utility Model Content

[0003] In view of this, this application provides a clamping device that is simple to operate and low in cost.

[0004] One embodiment of this application provides a clamping device. The clamping device includes: a carrier, a first clamping mechanism, a second clamping mechanism, and an eccentric wheel assembly. The carrier is configured to support a part. The first clamping mechanism is slidably connected to the carrier and has a receiving cavity and an inclined surface. One end of the second clamping mechanism extends into the receiving cavity and contacts the first clamping mechanism, while the other end of the second clamping mechanism extends out of the receiving cavity. The eccentric wheel assembly is mounted on the carrier. The eccentric wheel assembly is used to push the first clamping mechanism to move the second clamping mechanism along a first direction, so that the first clamping mechanism clamps the part in the first direction. The first clamping mechanism further drives the second clamping mechanism to move along the first direction, while the second clamping mechanism moves downward along the inclined surface, so that the second clamping mechanism clamps the part in a second direction.

[0005] This application provides a clamping device. By mounting an eccentric wheel assembly on a carrier, when the eccentric wheel assembly rotates, it pushes a first clamping mechanism to drive a second clamping mechanism to move along a first direction. When the eccentric wheel assembly rotates, it pushes the first clamping mechanism to drive the second clamping mechanism to move along the first direction, so that the first clamping mechanism clamps the part in the first direction. The eccentric wheel assembly further pushes the first clamping mechanism to drive the second clamping mechanism to move along the first direction, while the second clamping mechanism moves downward along the inclined surface, so that the second clamping mechanism clamps the part in a second direction. In the entire clamping process, no electrical components are relied upon, and the part is clamped in multiple directions. The operation is simple and the cost is low, meeting the current production needs.

[0006] In some embodiments of this application, the clamping device further includes a locking component, which is installed in the opening groove of the carrier and is used to unlock or lock the first clamping mechanism.

[0007] In some embodiments of this application, after the part is clamped, in order to prevent the first clamping mechanism and the second clamping mechanism from moving, the first clamping mechanism is locked by a locking assembly, thereby locking the second clamping mechanism and improving the clamping effect of the clamping device.

[0008] In some embodiments of this application, the first pressing mechanism includes a slider, a base, and a first spring. The base is located between the slider and the carrier and is slidably connected to the carrier. The slider is provided with a push block. The base is provided with a receiving groove for accommodating the first spring. The receiving groove includes a first wall and a second wall. One side of the base is provided with a through groove into which the push block can be inserted. The through groove is located above the receiving groove and communicates with each other. The push block is inserted into the through groove and is located between the first spring and the second wall to compress the first spring. The first spring pushes the base to move along the first direction to press the part in the first direction.

[0009] In some embodiments of this application, the slider and the base are slidably connected, and the base is slidably connected to the carrier. With the cooperation of the slider, the base and the eccentric wheel assembly, the parts are clamped in multiple directions. The entire clamping process does not rely on electrical components, is simple to operate and low in cost, and meets the existing production needs.

[0010] In some embodiments of this application, the base has a sliding portion at the end away from the slider, and the carrier has a sliding groove, with the sliding portion extending into the sliding groove to guide the base to move along the first direction.

[0011] In some embodiments of this application, the sliding part is guided to move by a groove, which is beneficial for limiting the position of the base.

[0012] In some embodiments of this application, the second pressing mechanism includes a pressing block housed within the receiving cavity. During the movement of the pressing block along the first direction by the first pressing mechanism, the pressing block is used to move downward along the inclined surface to press the part in the second direction.

[0013] In some embodiments of this application, when the pressure block is driven to the inclined surface by the first pressing mechanism, since the first pressing mechanism and the pressure block are slidably connected, the pressure block moves downward along the inclined surface relative to the first pressing mechanism to press the part in the second direction. The entire pressing process does not require any electrical components, the structure is simple, and it is beneficial to reduce costs.

[0014] In some embodiments of this application, the second pressing mechanism further includes a second spring, the first end of the pressing block is provided with a receiving cavity, the second end of the pressing block abuts against the slider, the first pressing mechanism includes a cover plate, the cover plate is used to cover the opening of the receiving cavity away from the inclined surface, the first end of the second spring is fixed inside the receiving cavity, the second end of the second spring is fixedly connected to the cover plate, and the second spring is used to push the pressing block to move downward along the inclined surface to press the part in the second direction.

[0015] In some embodiments of this application, the pressure block and the cover plate are connected by a second spring. The cover plate applies pressure to the second spring, causing the second spring to be in a compressed state. When the pressure block is driven to the inclined surface by the first pressing mechanism, since the first pressing mechanism and the pressure block are slidably connected, the pressure block moves downward relative to the first pressing mechanism along the inclined surface to press the part in the second direction.

[0016] In some embodiments of this application, the eccentric wheel assembly includes an eccentric wheel, a movable plate, a pin, and a handle mechanism. The eccentric wheel is located between the movable plate and the handle mechanism, and the eccentric wheel is fixedly connected to the handle mechanism. The movable plate is provided with a limiting groove. The first end of the pin is fixedly connected to the eccentric wheel, and the second end of the pin passes through the limiting groove. The pin is used to move along the limiting groove when the eccentric wheel rotates to push the movable plate. The movable plate then pushes the first pressing mechanism to drive the second pressing mechanism to move along the first direction.

[0017] In some embodiments of this application, the eccentric wheel is powered by a manually controlled handle mechanism. During the entire clamping process, the parts are clamped in multiple directions by a single power source, which solves the problem in related technologies that parts can only be clamped in one direction by a single power source. This meets the current production requirements. At the same time, the entire clamping process does not rely on any electrical components, which can save the layout space of the clamping device and thus reduce costs.

[0018] In some embodiments of this application, the movable plate is provided with push rods at both ends, the slider is provided with grooves adapted to the ends of the push rods, and the ends of the push rods are located in the grooves.

[0019] In some embodiments of this application, by setting push rods at both ends of the moving plate and installing the push rods in the grooves, two parts can be clamped simultaneously when the eccentric wheel rotates, thereby improving production efficiency.

[0020] In some embodiments of this application, the clamping device further includes a locking assembly, which includes a third spring and a locking block. The locking block is installed in the groove and has a locking groove. The first end of the third spring is fixed inside the locking groove, and the second end of the third spring is connected to the end away from the groove opening. The end of the locking block near the groove opening has a first inclined end face and a second inclined end face sequentially arranged along the second direction. The first inclined end face and the second inclined end face have the same inclination direction, and the inclination angle of the first inclined end face is greater than that of the second inclined end face. The first inclined end face is used to abut against the slider to unlock the base; the second inclined end face is used to abut against the base to lock the base.

[0021] In some embodiments of this application, by sequentially providing a first inclined end face and a second inclined end face along the second direction at one end of the locking block near the groove opening, the unlocking and self-locking of the base are realized, further improving the clamping effect of the clamping device.

[0022] In some embodiments of this application, the end of the slider away from the inclined surface is provided with a wedge-shaped surface adapted to the first inclined end surface, and the wedge-shaped surface is used to abut against the first inclined end surface; the end of the base away from the inclined surface is provided with an inclined surface adapted to the second inclined end surface, and the inclined surface is used to abut against the second inclined end surface, which further improves the self-locking and unlocking effect of the pressing device.

[0034] The following detailed description, in conjunction with the accompanying drawings, will further illustrate this application. Detailed Implementation

[0035] The technical solutions of the embodiments of this application will be described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0036] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.

[0037] Currently, clamping devices are typically used for positioning and clamping parts (such as electronic products and components). However, when performing multiple actions, existing clamping devices require a separate mechanism for each action, making operation complex and prone to errors. Furthermore, electrical components are also needed to perform these multiple actions. However, these electrical components suffer from limitations such as limited functionality, high cost, large space requirements, cumbersome operation, lack of error prevention, uncontrollable force, and significant safety hazards, thus failing to meet current production requirements.

[0038] Therefore, to solve the above-mentioned technical problems, embodiments of this application provide a clamping device. The clamping device includes a carrier, a first clamping mechanism, a second clamping mechanism, and an eccentric wheel assembly. The carrier is configured to support a part. The first clamping mechanism is slidably connected to the carrier and has a receiving cavity and an inclined surface. One end of the second clamping mechanism extends into the receiving cavity and contacts the first clamping mechanism, while the other end of the second clamping mechanism extends out of the receiving cavity. The eccentric wheel assembly is mounted on the carrier. The eccentric wheel assembly is used to push the first clamping mechanism to move the second clamping mechanism along a first direction, so that the first clamping mechanism clamps the part in the first direction. The first clamping mechanism further drives the second clamping mechanism to move along the first direction, and the second clamping mechanism moves downward along the inclined surface, so that the second clamping mechanism clamps the part in a second direction.

[0039] By mounting the eccentric wheel assembly on the carrier, when the eccentric wheel assembly rotates, it pushes the first clamping mechanism to drive the second clamping mechanism to move along the first direction. When the eccentric wheel assembly rotates, it pushes the first clamping mechanism to drive the second clamping mechanism to move along the first direction, so that the first clamping mechanism clamps the part in the first direction. The eccentric wheel assembly further pushes the first clamping mechanism to drive the second clamping mechanism to move along the first direction, while the second clamping mechanism moves downward along the inclined surface, so that the second clamping mechanism clamps the part in the second direction. In the entire clamping process, no electrical components are relied upon, and the part is clamped in multiple directions. The operation is simple and the cost is low, which meets the current production needs.

[0040] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0041] Please also refer to Figures 1 to 3One embodiment of this application provides a clamping device 100. The clamping device 100 includes a carrier 11, a first clamping mechanism 12, a second clamping mechanism 13, and an eccentric wheel assembly 14. The carrier 11 is configured to support a part. The first clamping mechanism 12 is slidably connected to the carrier 11. The first clamping mechanism 12 has a receiving cavity 120 and an inclined surface 121. One end of the second clamping mechanism 13 extends into the receiving cavity 120 and contacts the first clamping mechanism 12, while the other end of the second clamping mechanism 13 extends out of the receiving cavity 120. The eccentric wheel assembly 14 is mounted on the carrier 11. The eccentric wheel assembly 14 is used to push the first clamping mechanism 12 to move the second clamping mechanism 13 along a first direction, so that the first clamping mechanism 12 clamps the part in the first direction. The first clamping mechanism 12 further drives the second clamping mechanism 13 to move along the first direction, while the second clamping mechanism 13 moves downward along the inclined surface 121, so that the second clamping mechanism 13 clamps the part in a second direction.

[0042] In some embodiments of this application, by mounting the eccentric wheel assembly 14 on the carrier 11, when the eccentric wheel assembly 14 rotates, it pushes the first clamping mechanism 12 to drive the second clamping mechanism 13 to move along the first direction. When the eccentric wheel assembly 14 rotates, it pushes the first clamping mechanism 12 to drive the second clamping mechanism 13 to move along the first direction, so that the first clamping mechanism 12 clamps the part in the first direction. The eccentric wheel assembly 14 further pushes the first clamping mechanism 12 to drive the second clamping mechanism 13 to move along the first direction. At the same time, the second clamping mechanism 13 moves downward along the inclined surface 121, so that the second clamping mechanism 13 clamps the part in the second direction. In the entire clamping process, no electrical components are relied upon, and the part is clamped in multiple directions. The operation is simple and the cost is low, which meets the existing production needs.

[0043] In some embodiments of this application, see Figure 2 and Figure 3 As shown, O represents the origin of the coordinate system, X represents the first direction, and Y represents the second direction. The first direction X is perpendicular to the second direction Y.

[0044] Please also refer to Figures 4 to 6In some embodiments of this application, the first clamping mechanism 12 includes a slider 122, a base 123, and a first spring 124. The base 123 is located between the slider 122 and the carrier 11, and is slidably connected to the carrier 11. The slider 122 is provided with a pusher 1220. The base 123 is provided with a receiving groove 1230 for accommodating the first spring 124. The receiving groove 1230 includes a first wall 12301 and a second wall 12302. One side of the base 123 is provided with a through groove 12303 into which the pusher 1220 can be inserted. The through groove 12303 is located above the receiving groove 1230 and communicates with each other. The pusher 1220 is inserted into the through groove 12303 and is located between the first spring 124 and the second wall 12302 to compress the first spring 124. The first spring 124 pushes the base 123 to move in a first direction to clamp the part in the first direction.

[0045] In some embodiments of this application, the slider 122 and the base 123 are slidably connected, and the base 123 is slidably connected to the carrier 11. Through the cooperation of the slider 122, the base 123, and the eccentric wheel assembly 14, the part is clamped in multiple directions. Specifically, refer to... Figure 3 As shown, the dashed box represents the part. The slider 122 and the base 123 are slidably connected, and the base 123 is slidably connected to the carrier 11. When the eccentric wheel assembly 14 rotates, the eccentric wheel assembly 14 pushes the slider 122 to drive the second pressing mechanism 13 to move in the first direction. At the same time, the push block 1220 of the slider 122 compresses the first spring 124, and the elastic force of the first spring 124 pushes the base 123 to move toward the part.

[0046] In some embodiments of this application, a first angle and a second angle can be preset. For example, the first angle can be set to 90 degrees and the second angle can be set to 180 degrees. By presetting the first angle and the second angle, it is beneficial to better control the rotation angle of the eccentric wheel assembly 14. The operation is simple and the cost is low, which meets the existing production needs.

[0047] When the eccentric wheel assembly 14 rotates to the first angle, the base 123 can clamp the part in the first direction. As the eccentric wheel assembly 14 rotates from the first angle to the second angle, the base 123 remains stationary, and the slider 122, pushed by the eccentric wheel assembly 14, continues to drive the second clamping mechanism 13 to move along the first direction. Simultaneously, the second clamping mechanism 13 moves downward along the inclined surface 121. When the eccentric wheel assembly 14 rotates to the second angle, the second clamping mechanism 13 can clamp the part in the second direction. The entire clamping process does not rely on electrical components, is simple to operate, and has low cost, meeting current production needs.

[0048] In some embodiments of this application, the base 123 is provided with a sliding part 1231 at the end away from the slider 122, and the carrier 11 is provided with a sliding groove 111. The sliding part 1231 extends into the sliding groove 111. When the first spring 124 pushes the base 123 to move in the first direction, the sliding part 1231 moves in the sliding groove 111. The sliding groove 111 is used to guide the base 123 to move in the first direction.

[0049] In some embodiments of this application, the sliding part 1231 is guided to move by the groove 111, which is beneficial for limiting the base 123 on the one hand, and can also limit the sliding distance of the base 123 on the other hand.

[0050] In some embodiments of this application, the second clamping mechanism 13 includes a clamping block 130. The clamping block 130 is housed within a receiving cavity 120. As the first clamping mechanism 12 moves the clamping block 130 along a first direction, the clamping block 130 moves downward along an inclined surface 121 to clamp the part in a second direction.

[0051] In some embodiments of this application, when the pressure block 130 is driven to the inclined surface 121 by the first pressing mechanism 12, since the first pressing mechanism 12 and the pressure block 130 are slidably connected, the pressure block 130 moves downward along the inclined surface 121 relative to the first pressing mechanism 12 to press the part in the second direction. The entire pressing process does not require any electrical components, the structure is simple, and it is beneficial to reduce costs.

[0052] In some embodiments of this application, the pressure block 130 can be an L-shaped pressure block 130, with a pressure head 1302 extending from one end of the pressure block 130 along a first direction, and the pressure head 1302 pressing the part in a second direction.

[0053] In some embodiments of this application, the pressure block 130 and the pressure head 1302 can be an integrated design or separate components.

[0054] In some embodiments of this application, the second clamping mechanism 13 further includes a second spring 131. A first end of the clamping block 130 has a receiving cavity 1301. The second end of the clamping block 130 abuts against the slider 122. The first clamping mechanism 12 includes a cover plate 125. The cover plate 125 covers the opening of the receiving cavity 120 away from the inclined surface 121. The first end of the second spring 131 is fixed inside the receiving cavity 1301. The second end of the second spring 131 is fixedly connected to the cover plate 125. The second spring 131 pushes the clamping block 130 downwards along the inclined surface 121 to clamp the part in a second direction.

[0055] In some embodiments of this application, the pressure block 130 and the cover plate 125 are connected by a second spring 131. The cover plate 125 applies pressure to the second spring 131, so that the second spring 131 is in a compressed state. When the pressure block 130 is driven to the inclined surface 121 by the first pressing mechanism 12, since the first pressing mechanism 12 and the pressure block 130 are slidably connected, the pressure block 130 moves downward along the inclined surface 121 relative to the first pressing mechanism 12 to press the part in the second direction.

[0056] In some embodiments of this application, the elastic force of the second spring 131 can prevent the pressure block 130 from hitting the surface of the part during the pressing process, thus ensuring the safety of the part.

[0057] In some embodiments of this application, the eccentric wheel assembly 14 includes an eccentric wheel 140, a movable plate 141, a pin 142, and a handle mechanism 143. The eccentric wheel 140 is located between the movable plate 141 and the handle mechanism 143, and the eccentric wheel 140 is fixedly connected to the handle mechanism 143. The movable plate 141 is provided with a limiting groove 1410. The first end of the pin 142 is fixedly connected to the eccentric wheel 140. The second end of the pin 142 passes through the limiting groove 1410. The pin 142 is used to move along the limiting groove 1410 when the eccentric wheel 140 rotates, so as to push the movable plate 141, and through the movable plate 141, push the first pressing mechanism 12 to drive the second pressing mechanism 13 to move along a first direction.

[0058] In some embodiments of this application, the eccentric wheel 140 is powered by the manually controlled handle mechanism 143. During the entire clamping process, the parts are clamped in multiple directions by a single power source, which solves the problem in the related art that the parts can only be clamped in one direction by a single power source. This meets the current production requirements. At the same time, the entire clamping process does not rely on any electrical components, which can save the layout space of the clamping device 100 and thus reduce costs.

[0059] In some embodiments of this application, by setting a handle mechanism 143, the problem of uncontrollable force of electrical components can be avoided, ensuring production yield. At the same time, manual operation is conducive to operation at any time, thereby improving the availability of the pressing device 100.

[0060] In some embodiments of this application, push rods 1411 are provided at both ends of the movable plate 141. The slider 122 is provided with a groove 1221 that matches the end of the push rod 1411. The end of the push rod 1411 is located in the groove 1221.

[0061] In some embodiments of this application, by providing push rods 1411 at both ends of the moving plate 141 and installing the push rods 1411 in the groove 1221, the eccentric wheel 140 can clamp two parts simultaneously when it rotates, thereby improving production efficiency.

[0062] In some embodiments of this application, see Figure 7 As shown, the clamping device 100 also includes a locking assembly 15. The locking assembly 15 is installed within the opening slot 110 of the carrier 11. The locking assembly 15 is in its initial state. See reference. Figure 8 As shown, at the first angle, the locking assembly 15 unlocks the first clamping mechanism 12. (See reference...) Figure 9 As shown, at the second angle, the locking assembly 15 locks the first pressing mechanism 12.

[0063] In some embodiments of this application, after the parts are clamped, in order to prevent the first clamping mechanism 12 and the second clamping mechanism 13 from moving, the first clamping mechanism 12 is locked by the locking assembly 15, thereby locking the second clamping mechanism 13, which improves the clamping effect of the clamping device 100.

[0064] In some embodiments of this application, the locking assembly 15 includes a third spring 150 and a locking block 151. The locking block 151 is installed in a groove 1221. The locking block 151 has a locking groove 1510. The first end of the third spring 150 is fixed inside the locking groove 1510, and the second end of the third spring 150 is connected to the end away from the opening of the groove 1221. The end of the locking block 151 near the opening of the groove 1221 has a first inclined end face 1511 and a second inclined end face 1512 sequentially arranged along a second direction. The first inclined end face 1511 and the second inclined end face 1512 have the same inclination direction, and the inclination angle of the first inclined end face 1511 is greater than the inclination angle of the second inclined end face 1512. At the first angle, the first inclined end face 1511 abuts against the slider 122 to unlock the base 123. At the second angle, the second inclined end face 1512 abuts against the base 123 to lock the base 123.

[0065] In some embodiments of this application, by sequentially providing a first inclined end face 1511 and a second inclined end face 1512 along the second direction at one end of the locking block 151 near the groove 1221, during the process of the base 123 pressing the part along the first direction, the first inclined end face 1511 abuts against the slider 122, causing the base 123 to move under the action of the second spring 131 until the eccentric wheel assembly 14 rotates to the second angle, the second direction of the part is pressed, and the second inclined end face 1512 abuts against the base 123 to lock the base 123, avoiding the problem of the base 123 moving after the part is pressed, and while realizing the pressing of the part in multiple directions, the self-locking and unlocking of the pressing mechanism are realized, further improving the pressing effect of the pressing device 100.

[0066] In some embodiments of this application, the end of the slider 122 away from the inclined surface 121 is provided with a wedge-shaped surface 1222 adapted to the first inclined end surface 1511, and the wedge-shaped surface 1222 is used to abut against the first inclined end surface 1511. The end of the base 123 away from the inclined surface 121 is provided with an inclined surface 1232 adapted to the second inclined end surface 1512, and the inclined surface 1232 is used to abut against the second inclined end surface 1512.

[0067] In some embodiments of this application, the self-locking and unlocking effects of the clamping device 100 are further improved by the wedge-shaped surface 1222 abutting against the first inclined end surface 1511 and the inclined surface 1232 abutting against the second inclined end surface 1512.

[0068] In some embodiments of this application, the eccentric wheel assembly 14 further includes a mounting plate 144. The mounting plate 144 is fixedly connected to the carrier 11 and is located on the side of the movable plate 141 near the eccentric wheel 140. A plurality of stop blocks 1440 are provided on the side of the mounting plate 144 near the handle mechanism 143. The plurality of stop blocks 1440 are located on the side near the inclined surface 121. The plurality of stop blocks 1440 can limit the rotation angle of the eccentric wheel assembly 14. When the eccentric wheel assembly 14 rotates to a second angle, the stop blocks 1440 prevent the eccentric wheel assembly 14 from continuing to rotate, avoiding the problem of the eccentric wheel assembly 14 continuing to rotate after the part is clamped, improving the clamping safety of the clamping device 100, and ensuring the yield of the produced parts.

[0069] In some embodiments of this application, the clamping device 100 further includes a spring mechanism 16. A first end of the spring mechanism 16 is fixedly connected to the carrier 11. A second end of the spring mechanism 16 abuts against the handle mechanism 143. The spring mechanism 16 is used to prevent the handle mechanism 143 from loosening.

[0070] In some embodiments of this application, the mounting plate 144 is provided with a through hole 1441. The handle mechanism 143 further includes a slide plate 1430, a handle 1431, and a fixed shaft 1432. The handle 1431 is mounted on the end face of the slide plate 1430 away from the eccentric wheel 140. The slide plate 1430 is fixedly connected to the eccentric wheel 140 via the fixed shaft 1432. The second end of the spring mechanism 16 passes through the through hole 1441 and abuts against the side of the slide plate 1430 near the top plate.

[0071] In some embodiments of this application, when the eccentric wheel assembly 14 rotates to the second angle, if the part has been processed, when the eccentric wheel assembly 14 rotates from the second angle to the first angle, the eccentric wheel assembly 14 pushes the first clamping mechanism 12 to drive the second clamping mechanism 13 to move in the opposite direction of the first direction. At the same time, the second clamping mechanism 13 moves upward along the inclined surface 121 so that the second clamping mechanism 13 moves away from the part in the second direction. Further, when the eccentric wheel assembly 14 rotates from the first angle to the initial angle, the eccentric wheel assembly 14 pushes the first clamping mechanism 12 to drive the second clamping mechanism 13 to move in the opposite direction of the first direction until the base 123 moves away from the part in the first direction.

[0072] In some embodiments of this application, see Figure 4 As shown, the pin 142 and the limiting groove 1410 are located on the side of the deflector 140 near the opening groove 110. If the pin 142 and the limiting groove 1410 are located on the side near the opening groove 110, refer to... Figure 7 As shown, the locking assembly 15 is in its initial state. When the deflector wheel 140 rotates clockwise by a first angle relative to the fixed shaft 1432, refer to... Figure 8 As shown, the wedge-shaped surface 1222 abuts against the first inclined end face 1511 to unlock the base 123. When the deflector wheel 140 rotates clockwise relative to the fixed shaft 1432 from the first angle to the second angle, refer to... Figure 9 As shown, the inclined surface 1232 abuts against the second inclined end surface 1512 to lock the base 123, thus preventing the base 123 from moving after the part is clamped, improving the clamping safety of the clamping device 100, and ensuring the yield of the produced parts.

[0073] In some other embodiments, when the pin 142 and the limiting groove 1410 are located on the side away from the opening groove 110, the deflector wheel 140 can rotate counterclockwise relative to the fixed shaft 1432 to lock and unlock the base 123.
