[0029] Please refer to Figure 1 and Figure 2 , Figure 1 and Figure 2 all show a clamping device 100 provided by the present application.

[0030] In the embodiments of the present application, the clamping device 100 can clamp the workpiece 200. The workpiece 200 has uneven structures on the surface. The clamping device 100 can include a receiving mechanism 101 and a pressing plate 102. The receiving mechanism 101 can be adapted to and fit the uneven side of the workpiece 200, so that the receiving mechanism 101 can be relatively fixed with the workpiece 200 when receiving the workpiece 200, reducing the shaking of the workpiece 200 on the receiving mechanism 101. The pressing plate 102 can press on the other side of the workpiece 200 and be detachably connected with the receiving unit. When the pressing plate 102 is relatively fixed with the receiving mechanism 101, the clamping device 100 realizes the clamping and fixing of the workpiece 200, at this time the workpiece 200 can be synchronized with the clamping device 100 into a machining equipment (not shown) for fixing, and then the machining equipment can process the workpiece 200.

[0031] Among them, for different specifications of the workpiece 200, the positions of the uneven structures are different and / or the volumes of the uneven structures are different, the receiving mechanism 101 can determine the position and volume of the uneven structure on the workpiece 200 by abutting against the uneven structure on the workpiece 200, and adjust the height of each part used to contact the workpiece 200 according to the position and volume of the uneven structure on the workpiece 200, so that the receiving mechanism 101 forms a profiled groove adapted to the uneven structure of the workpiece 200, so that the receiving mechanism 101 adapts to the workpiece 200 received. At the same time, the same pressing plate 102 or the pressing plate 102 corresponding to the specification of the workpiece 200 can be installed on the receiving mechanism 101 by the worker, so that the pressing plate 102 cooperates with the receiving mechanism 101 to clamp and fix the workpiece 200.

[0032] In the embodiments of the present application, the type of detachable connection is not specifically limited. For example, the detachable connection can be, but is not limited to, screw connection, threaded connection, buckle connection, etc.

[0033] For example, the workpiece 200 can be an eyeshade for covering the eyes of a user. The workpiece 200 includes two sub-parts 201, which can cover the two eyes of the user respectively, and each sub-part 201 has an arc-shaped protruding structure on the side used to abut against the receiving mechanism 101, and a through hole is formed on each sub-part 201. When the workpiece 200 is received on the receiving mechanism 101 and the pressing plate 102 is pressed on the workpiece 200, the worker can pass the screw through the through hole of the pressing plate 102 and the workpiece 200, and screw the screw on the receiving mechanism 101, so as to realize the relative fixation of the receiving mechanism 101 and the pressing plate 102, and realize the clamping and fixing of the workpiece 200 by the receiving mechanism 101 and the pressing plate 102.

[0034] In the embodiments of the present application, the type of machining equipment is not specifically limited. For example, the machining equipment can be, but is not limited to, a numerical control lathe, and the machining equipment can cut the workpiece 200.

[0035] In the embodiments of the present application, the length direction, the width direction and the height direction of the clamping device 100 can be defined as the first horizontal direction, the second horizontal direction and the vertical direction respectively. For example, the first horizontal direction can be the X direction and the opposite direction thereof as shown in the drawings, the second horizontal direction can be the Y direction and the opposite direction thereof as shown in the drawings, and the vertical direction can be the Z direction and the opposite direction thereof as shown in the drawings. Figure 2 Figure 1 Figure 2 Figure 1 Figure 2

[0036] Please refer to Figure 3 and Figure 4 In some embodiments, the receiving mechanism 101 can include a base 10, a limiting piece 20 and a receiving unit. The base 10 is detachably connected to the processing equipment. The number of limiting pieces 20 can be multiple, the number of receiving units can be multiple, and the number of limiting pieces 20 can be twice the number of receiving units, and each receiving unit is provided with two limiting pieces 20. The plurality of receiving units can be arranged at intervals in the first horizontal direction. The two limiting pieces 20 corresponding to the same receiving unit can be defined as a group of limiting pieces 20. The plurality of groups of limiting pieces 20 can be arranged at intervals in the first horizontal direction.

[0037] The plurality of limiting pieces 20 are detachably connected to the base 10. In each group of limiting pieces 20, the two limiting pieces 20 are symmetrically arranged and arranged at intervals in the second horizontal direction. The corresponding receiving unit can be located between the two limiting pieces 20. Each receiving unit can include a bottom plate 30. In each group of limiting pieces 20, each limiting piece 20 is provided with a limiting slot 21 on the side facing the other limiting piece 20, and the limiting slot 21 penetrates the side of the limiting piece 20 close to the base 10 in the vertical direction. The bottom plate 30 can be disc-shaped. Part of the structure of the bottom plate 30 enters the limiting slot 21 of the corresponding two limiting pieces 20, and the top wall of each limiting slot 21 in the vertical direction and the base 10 can clamp the corresponding bottom plate 30, thereby limiting the movement of the corresponding bottom plate 30 in the vertical direction.

[0038] ​​​​​When the limiting member 20 is not fixed on the base 10, the bottom plate 30 can be rotationally fitted with each inner wall of the corresponding limiting groove 21 and the base 10, and the bottom plate 30 can also be slidably fitted with each inner wall of the corresponding limiting groove 21 and the base 10 in the first horizontal direction. In this way, before the limiting member 20 is fixed on the base 10, each bottom plate 30 can move and rotate on the base 10 in the first horizontal direction, so as to adjust the position of the corresponding receiving mechanism 101 on the base 10, so that the position of the receiving unit can be adjusted according to the position of the received sub-part 201. After the position adjustment of the receiving unit is completed, the worker can fix the limiting member 20 on the base 10, so that the base 10 is fitted and fixed with the top wall of the limiting groove 21 to clamp the corresponding bottom plate 30, thereby limiting the movement of the receiving unit, reducing the probability of movement of the workpiece 200 when the workpiece 200 is clamped by the clamping device 100, and improving the yield rate of the workpiece 200 processing.

[0039] It can be understood that the worker can adjust the position and angle of the receiving unit on the base 10 according to the specifications of the workpiece 200, and then clamp and fix the receiving unit by fixing the limiting member 20 on the base 10. For example, the limiting member 20 can be detachably connected to the base 10 by a screw. By loosening the screw, the clamping of the limiting member 20 and the base 10 on the bottom plate 30 can be released, so that the receiving unit can rotate and move in the first horizontal direction. By tightening the screw, the clamping of the limiting member 20 and the base 10 on the bottom plate 30 can be achieved, so as to limit the movement and rotation of the receiving unit.

[0040] It can be understood that the worker can set a corresponding number of receiving units and limiting members 20 on the base 10 according to the specifications of the workpiece 200. In the embodiments of the present application, the number of receiving units and the number of limiting members 20 are not specifically limited. For example, the number of receiving units is two, and the two receiving units are arranged at intervals in the first horizontal direction. The base 10 is provided with two groups of limiting members 20, and each group of limiting members 20 is used to limit the movement and rotation of the corresponding receiving unit.

[0041] Please refer to Figure 5 and Figure 6 In some embodiments, each receiving unit can further include a support assembly 40, a receiving member 50, a resilient member 60, a clamping head 70, and a driving assembly 80.

[0042] The support assembly 40 can include a support base 41, a first connecting plate 42, a partition plate 43, and a locking piece 44. The support base 41 can be cylindrical. The support base 41 is fixedly installed on the bottom plate 30, and the diameter of the support base 41 is smaller than that of the bottom plate 30. The support base 41 is provided with a receiving space 411, and the side of the support base 41 away from the bottom plate 30 is open. A plurality of lock holes 412 are formed in the peripheral wall of the support base 41, which can be spaced apart from the receiving space 411 and arranged along the direction surrounding the support base 41.

[0043] The partition plate 43 can be disc-shaped. The partition plate 43 is received in the receiving space 411, and the partition plate 43 is spaced apart from the bottom wall of the receiving space 411 in the vertical direction. A plurality of lock grooves 431 are formed in the peripheral wall of the partition plate 43 and arranged along the direction surrounding the partition plate 43. The plurality of lock grooves 431 correspond one-to-one to the plurality of lock holes 412. The partition plate 43 is also provided with a plurality of sliding grooves 432, which are spaced apart and each penetrates the partition plate 43 in the vertical direction. The partition plate 43 can divide the receiving space 411 into two subspaces spaced apart in the vertical direction, and each sliding groove 432 communicates with the receiving space 411, thereby communicating the two subspaces.

[0044] The plurality of locking pieces 44 can correspond one-to-one to the plurality of lock holes 412 and one-to-one to the plurality of lock grooves 431. Each locking piece 44 can pass through the corresponding lock hole 412 and enter the corresponding lock groove 431, thereby limiting the rotation of the partition plate 43 and the movement of the partition plate 43 in the vertical direction. At the same time, the inner wall of the receiving space 411 can limit the movement of the partition plate 43 in other directions perpendicular to the vertical direction.

[0045] The side of the support base 41 away from the bottom plate 30 can be provided with a first positioning groove 413, which can communicate with the receiving space 411 and form an opening on the support base 41. The first connecting plate 42 can be at least partially received in the first positioning groove 413. The first connecting plate 42 can shield the receiving space 411. The side of the first connecting plate 42 away from the receiving space 411 can be provided with a plurality of connecting grooves 421, which are spaced apart.

[0046] Please refer to Figure 7 and Figure 8The number of the clamping heads 70 is multiple, and the clamping heads 70 can be made of elastic material. The multiple clamping heads 70 correspond to the multiple connecting grooves 421 one by one. Each clamping head 70 can include a fixed part 71 and multiple movable parts 72. The fixed part 71 can be in a cylindrical shape. Each fixed part 71 can be at least partially accommodated in the corresponding connecting groove 421 and kept relatively fixed with the first connecting plate 42. Each movable part 72 can be fixedly connected to the corresponding fixed part 71 at an end away from the accommodation space 411 in the vertical direction. In each clamping head 70, the multiple movable parts 72 can be arranged at intervals in the direction surrounding the fixed part 71, and the distance between the top end of each movable part 72 in the vertical direction and the central axis of the fixed part 71 is less than the distance between the bottom end and the central axis.

[0047] The number of the receiving members 50 is multiple. The multiple receiving members 50 can correspond to the multiple sliding grooves 432 one by one, correspond to the multiple connecting grooves 421 one by one, and correspond to the multiple clamping heads 70 one by one. Each receiving member 50 is arranged along the vertical direction through the first connecting plate 42 and the corresponding fixed part 71, and the receiving member 50 can move relatively with the first connecting plate 42 and the fixed part 71 in the vertical direction. When the receiving member 50 passes through the fixed part 71, the corresponding multiple movable parts 72 can be arranged around the receiving member 50. The bottom end of the receiving member 50 in the vertical direction enters the accommodation space 411, and can pass through the corresponding sliding groove 432 with the movement of extending into the accommodation space 411 in the vertical direction. The top end of the receiving member 50 in the vertical direction can be in contact with the surface of the workpiece 200 having uneven structure.

[0048] The number of the elastic members 60 can be multiple, and the multiple elastic members 60 are accommodated in the accommodation space 411. The multiple elastic members 60 correspond to the multiple receiving members 50 one by one. Each elastic member 60 can be connected to the corresponding receiving member 50 and drive the receiving member 50 to extend out of the accommodation space 411 in the vertical direction by the elastic force generated by the elastic deformation of the elastic member 60.

[0049] The driving assembly 80 can move relative to the support base 41 and drive the movable part 72 of each clamping head 70 to move and deform. When the workpiece 200 is clamped by the plurality of receiving members 50 and at least some of the receiving members 50 collide with the uneven position of the workpiece 200, the receiving members 50 extend into the receiving space 411 against the elastic force of the elastic members 60, and the receiving unit has been adapted to the uneven structure of the workpiece 200. Then, the worker can operate the driving assembly 80 to move the driving assembly 80 relative to the support base 41, so as to push each movable part 72 to abut against the corresponding receiving member 50 and press the movable part 72 to elastically deform, thereby increasing the abutting area between the movable part 72 and the receiving member 50 and improving the fastening degree of the movable part 72 and the receiving member 50. In this way, the movement of the plurality of receiving members 50 in the vertical direction can be limited by the friction between the movable part 72 and the receiving member 50 after the receiving unit is adapted to the workpiece 200, so that the plurality of receiving members 50 of the receiving mechanism 101 can stably clamp the plurality of parts of the workpiece 200, and the receiving unit can stably clamp the workpiece 200 and keep relative static with the workpiece 200. Then, the worker can install the pressing plate 102 on the receiving unit to clamp and fix the workpiece 200 by the pressing plate 102 and the receiving mechanism 101.

[0050] When the specification of the workpiece 200 to be clamped changes, the worker can operate the driving assembly 80 to reduce the pressure of the driving assembly 80 on the plurality of movable parts 72, so that the movable part 72 can restore to the state before deformation by its own elasticity. At this time, the plurality of receiving members 50 are separated from the plurality of movable parts 72, and after the workpiece 200 on the receiving member 50 is removed, the plurality of receiving members 50 can extend out of the receiving space 411 to the initial height under the driving of the plurality of elastic members 60. Then, the worker can place another specification of the workpiece 200 to be clamped on the plurality of receiving members 50, and again operate the driving assembly 80 to adapt the receiving unit to the workpiece 200, and install the pressing plate 102 on the receiving unit to clamp and fix the workpiece 200 by the pressing plate 102 and the receiving mechanism 101.

[0051] In the embodiments of the present application, the type of the locking member 44 is not specifically limited. For example, the locking member 44 can be a screw, the locking member 44 can be threadedly connected with the lock hole 412 of the support base 41, and one end of the locking member 44 can extend into the corresponding lock groove 431 and abut against the inner wall of the lock groove 431 to limit the movement and rotation of the partition plate 43.

[0052] For example, the support base 41 and the corresponding bottom plate 30 can be fixedly connected by screws. The screws can pass through the bottom of the support base 41 in the vertical direction through the bottom wall of the receiving space 411 and be threadedly connected with the bottom plate 30. The partition plate 43 can shield the screws connected to the support base 41 and the bottom plate 30.

[0053] In the embodiments of the present application, the type of the elastic member 60 is not specifically limited. For example, the elastic member 60 can be, but is not limited to, a spring.

[0054] In the embodiments of the present application, the material of the clamping head 70 is not specifically limited. For example, the material of the clamping head 70 can be, but is not limited to, silica gel, rubber, etc.

[0055] It can be understood that a plurality of through holes can be formed on the first connecting plate 42, and the plurality of through holes can correspond to the plurality of connecting grooves 421 one by one. Each through hole is in communication with the corresponding connecting groove 421, and the diameter of each through hole is smaller than the diameter of the corresponding connecting groove 421 and greater than or equal to the diameter of the part of the receiving member 50 for passing through the through hole. In this way, each fixing part 71 can be maintained in the corresponding connecting groove 421 without entering the receiving space 411, and the receiving member 50 can pass through the first connecting plate 42 and the corresponding clamping head 70.

[0056] It can be understood that when the receiving member 50 is separated from the corresponding movable part 72, the workpiece 200 placed on the receiving member 50 can drive the receiving member 50 to descend by gravity, so as to extend into the receiving space 411. At this time, the descending receiving member 50 can pass through the corresponding sliding groove 432, and the sliding groove 432 can limit the movement track of the receiving member 50 to avoid the receiving member 50 from tilting during the descending process and failing to fit the deformed movable part.

[0057] At the same time that the receiving member 50 descends, the corresponding elastic member 60 is compressed to be elastically deformed. When the receiving member 50 fits the movable part 72, the clamping head 70 clamps and fixes the receiving member 50 to limit the movement of the receiving member 50 in the vertical direction. At this time, the elastic member 60 remains in the compressed state. After the movable part 72 is separated from the receiving member 50 and the workpiece 200 is removed from the receiving member 50, the elastic member 60 can restore to the original state under the action of the elastic force generated by the elastic deformation of the elastic member 60 itself, and drive the corresponding receiving member 50 to rise to the initial height.

[0058] For example, a threaded groove 811 can be formed on the first connecting plate 42, and the plurality of receiving members 50 can be arranged to avoid the threaded groove 811. The threaded groove 811 can be used for the screws of the pressing plate 102 to pass through and be threadedly connected with the screws, so as to realize the relative fixation of the bearing mechanism and the pressing plate 102.

[0059] In some embodiments, each receiving member 50 can include a movable rod 51 and an abutting head 52. The movable rod 51 can pass through the first connecting plate 42 and the fixing portion 71, and can partially enter the receiving space 411 and the sliding groove 432. The abutting head 52 is made of elastic material. The abutting head 52 can be fixedly connected to one end of the movable rod 51 away from the receiving space 411 in the vertical direction. The abutting head 52 can abut against the workpiece 200 to achieve the receiving of the workpiece 200 by the receiving member 50.

[0060] In the embodiments of the present application, the material of the abutting head 52 is not specifically limited. For example, the material of the abutting head 52 can be, but is not limited to, rubber, silicone, etc.

[0061] It can be understood that the abutting head 52 made of elastic material can be deformed under the gravity of the workpiece 200 when abutting against the workpiece 200, and the deformed shape can be adapted to the position where the workpiece 200 abuts against the abutting head 52. In this way, the abutting head 52 can protect the side of the workpiece 200 facing the receiving mechanism 101, and reduce the probability of damage of the workpiece 200 due to contact with hard structures.

[0062] For example, the top end of the movable rod 51 can be provided with a slot 511, the bottom of the abutting head 52 can be inserted into the slot 511, and the inner wall of the slot 511 can extrude the bottom of the abutting head 52 to make it swell, increase the contact area between the abutting head 52 and the inner wall of the slot 511, strengthen the stability of the connection between the movable rod 51 and the abutting head 52 through friction, and realize the fixed connection between the movable rod 51 and the abutting head 52 through the insertion mode.

[0063] In some embodiments, each movable rod 51 can include a first rod portion 512, a limiting ring 513, and a second rod portion 514. The second rod portion 514 is located on the side of the first rod portion 512 close to the bottom plate 30 in the vertical direction, and is fixedly connected with the first rod portion 512. The first rod portion 512 and the second rod portion 514 both extend in the vertical direction. The first rod portion 512 can pass through the first connecting plate 42 and the corresponding fixing portion 71, and the first rod portion 512 can be attached to the corresponding movable portion 72. The top end of the first rod portion 512 can be fixedly connected with the abutting head 52. The diameter of the first rod portion 512 can be equal to or less than the diameter of the through hole on the first connecting plate 42 for the first rod portion 512 to pass through. The diameter of the second rod portion 514 is less than the diameter of the first rod portion 512, and is less than or equal to the diameter of the corresponding sliding groove 432.

[0064] The limiting ring 513 is protruded from the peripheral wall of the first rod part 512 and is located at the bottom end of the peripheral wall of the first rod part 512. The limiting ring 513 is located in the accommodation space 411, and the diameter of the outer circle of the limiting ring 513 is greater than the diameter of the through hole of the first connecting plate 42 for the first rod part 512 to pass through and is greater than the diameter of the corresponding sliding groove 432. The elastic member 60 can be sleeved on the corresponding second rod part 514, and the two ends of the elastic member 60 can abut against the partition plate 43 and the side of the corresponding limiting ring 513 facing the partition plate 43, respectively.

[0065] For example, the top end of the first rod part 512 can be provided with a slot 511, and the abutting head 52 is inserted into the slot 511 to fix the first rod part 512 and the movable rod 51.

[0066] It can be understood that when the receiving member 50 descends, part of the structure of the first rod part 512 can enter the accommodation space 411, and the second rod part 514 can enter the sliding groove 432 and be connected with the sliding groove 432 in the vertical direction, thereby limiting the movement track of the receiving member 50. At the same time, the limiting ring 513 descends synchronously and can push the elastic member 60 to be compressed.

[0067] When the receiving member 50 is separated from the movable part 72 and the workpiece 200 on the receiving member 50 is removed, the elastic member 60 can drive the limiting ring 513 to ascend by the elastic force of the elastic member 60, so that the first rod part 512 and the second rod part 514 ascend synchronously. The limiting ring 513 can abut against the side of the first connecting plate 42 facing the bottom plate 30 to limit the ascending distance of the receiving member 50. In this way, the probability that the receiving member 50 is completely removed from the accommodation space 411 under the driving of the elastic force of the elastic member 60 can be reduced.

[0068] For example, the first rod part 512, the second rod part 514 and the limiting ring 513 can be integrally formed.

[0069] In some embodiments, the driving assembly 80 can include a driving ring 81 and a second connecting plate 82. The driving ring 81 can be a circular ring. The driving ring 81 can be provided with a threaded groove 811 on the side facing the bottom plate 30 in the vertical direction, and the threaded groove 811 can accommodate at least part of the structure of the supporting seat 41 away from the bottom plate 30. The driving ring 81 can be connected with the supporting seat 41 in a threaded manner through the threaded groove 811.

[0070] The top wall of the thread groove 811 in the vertical direction can be provided with a second positioning groove 812. The second positioning groove 812 can accommodate the second connecting plate 82. The second connecting plate 82 can be rotationally fitted with the inner wall of the second positioning groove 812. The second connecting plate 82 is arranged in the vertical direction with the first connecting plate 42, and the second connecting plate 82 is located on the side of the first connecting plate 42 away from the bottom plate 30. The side of the second connecting plate 82 facing the first connecting plate 42 is provided with a plurality of extrusion grooves 821. The plurality of extrusion grooves 821 correspond one-to-one with the plurality of clamping heads 70, and each extrusion groove 821 can accommodate a plurality of movable parts 72 in the corresponding clamping head 70. In each extrusion groove 821, the diameter of the top of the extrusion groove 821 in the vertical direction is smaller than the diameter of the bottom.

[0071] It can be understood that when the receiving member 50 can move in the vertical direction, the plurality of movable parts 72 can partially enter the corresponding extrusion groove 821, thereby supporting the second connecting plate 82. At this time, the driving ring 81 is not tightened.

[0072] After the receiving member 50 receives the workpiece 200, the worker can rotate the driving ring 81 to make the driving ring 81 descend in the vertical direction, at this time, the plurality of movable parts 72 entering the extrusion groove 821 can limit the rotation of the second connecting plate 82, so that the driving ring 81 and the second connecting plate 82 can be relatively rotated and descend synchronously with the driving ring 81. The diameter of the extrusion groove 821 gradually decreases from bottom to top, so that the inner wall of the extrusion groove 821 can extrude the plurality of movable parts 72 when the second connecting plate 82 descends. The inner wall of each extrusion groove 821 can push the corresponding plurality of movable parts 72, so that the top ends of the plurality of movable parts 72 are close to each other, thereby approaching and abutting the corresponding first rod part 512. At the same time, the first connecting plate 42 can cooperate with the second connecting plate 82 to extrude the structure located outside each movable part 72 in the extrusion groove 821, thereby cooperating to drive each movable part 72 into the extrusion groove 821 and elastically deform.

[0073] When the driving ring 81 is reversely rotated, the pressure of the second connecting plate 82 on the plurality of clamping heads 70 decreases, and the plurality of movable parts 72 can drive the second connecting plate 82 to rise under the action of the elastic force generated after the elastic deformation of the plurality of movable parts 72, and the plurality of movable parts 72 can restore the initial shape under the action of the elastic force, that is, the top ends of the plurality of movable parts 72 in the same clamping head 70 can be away from each other, and the plurality of movable parts 72 can be separated from the corresponding receiving member 50.

[0074] In this way, after the workpiece 200 is received by the receiving member 50, the worker can fix the positions of the plurality of receiving members 50 in the vertical direction by tightening the driving ring 81, so that the receiving member 50 maintains the adaptation to the workpiece 200 and can continuously receive other workpieces 200 of the same specification. When the specification of the received workpiece 200 changes, the worker can remove the workpiece 200 from the receiving mechanism 101 and loosen the driving ring 81, so that the plurality of movable parts 72 are driven to return to the initial shape by the elastic force of the movable parts 72 themselves, and push the second connecting plate 82 away from the first connecting plate 42; after the movable parts 72 return to the initial state, the movable parts 72 are separated from the receiving member 50, so that the plurality of receiving members 50 can be lifted to the initial height under the elastic driving of the elastic member 60. The worker can then place another workpiece 200 of a different specification on the receiving mechanism 101, so that the receiving mechanism 101 adapts to the workpiece 200.

[0075] For example, in each clamping head 70, the plurality of movable parts 72 surround the top of the circular truncated cone, and the diameter of the top is smaller than the diameter of the bottom. The outer side wall of each movable part 72 can be inclined, and the side wall of each extrusion groove 821 can be inclined.

[0076] It can be understood that the plurality of receiving members 50 in the receiving mechanism 101 can move in the vertical direction by a corresponding distance according to the uneven structure on the workpiece 200, and then the worker can fix the positions of the receiving members 50 by tightening the driving ring 81, so that the receiving members 50 can adapt to and receive the workpiece 200 of the current specification. In this way, compared with the general technology in the related art, which requires different receiving members to be designed and manufactured for different specifications of workpieces 200, the present application can achieve the receiving of different specifications of products by one receiving mechanism 101, which can reduce the workload of the worker in producing jigs before processing the workpiece 200, and can improve the convenience of processing the workpiece 200.

[0077] By means of the receiving mechanism 101 and the clamping device 100 provided by the embodiments of the present application, when a workpiece 200 is clamped and fixed, the worker can first adjust the number and position of the receiving units on the base 10 according to the number and position of the sub-parts 201 on the workpiece 200, and then fix the limiting member 20 on the base 10 to achieve the installation of the receiving units on the base 10.

[0078] Then, the worker can place the workpiece 200 on the receiving mechanism 101, so that the abutting heads 52 of the plurality of receiving pieces 50 abut against the workpiece 200; at this time, each movable part 72 is not completely attached to the corresponding receiving piece 50. Each receiving piece 50 can be lowered by a corresponding distance under the action of the gravity of the workpiece 200, the second rod part 514 of each receiving piece 50 can enter the corresponding sliding groove 432, and the corresponding elastic piece 60 is compressed. Then the worker can tighten the drive ring 81, so that the second connecting plate 82 is close to the first connecting plate 42, the depth of each movable part 72 entering the corresponding extrusion groove 821 is increased, the inner wall of each extrusion groove 821 can push the corresponding movable part 72 close to the receiving piece 50 and attached to the receiving piece 50, and each movable part 72 can be deformed under the extrusion of the first connecting plate 42 and the second connecting plate 82. The movable part 72 attached to the receiving piece 50 can limit the movement of the receiving piece 50 in the vertical direction, at this time the height of the plurality of receiving pieces 50 can be kept fixed, and the support of the plurality of positions of the uneven side of the workpiece 200 is maintained, so that the receiving mechanism 101 is adapted to the specification of the workpiece 200. Then the worker can place the pressing plate 102 on the side of the workpiece 200 away from the receiving mechanism 101, and connect the pressing plate 102 with the receiving mechanism 101, so as to realize clamping of the workpiece 200.

[0079] When the specification of the workpiece 200 being clamped changes, the worker can remove the pressing plate 102 from the receiving mechanism 101, loosen the drive ring 81, and remove the workpiece 200 from the receiving mechanism 101, so that the plurality of movable parts 72 returns to the original state, and the plurality of receiving pieces 50 can be reset to the initial height, then the worker can place another specification of the workpiece 200 to be clamped on the receiving mechanism 101, so that the receiving mechanism 101 can again adapt to the specification of the workpiece 200.

[0080] In this way, the workpiece 200 can be placed on the receiving mechanism 101, so that the abutting heads 52 of the plurality of receiving pieces 50 abut against the workpiece 200; at this time, each movable part 72 is not completely attached to the corresponding receiving piece 50. Each receiving piece 50 can be lowered by a corresponding distance under the action of the gravity of the workpiece 200, the second rod part 514 of each receiving piece 50 can enter the corresponding sliding groove 432, and the corresponding elastic piece 60 is compressed. Then the worker can tighten the drive ring 81, so that the second connecting plate 82 is close to the first connecting plate 42, the depth of each movable part 72 entering the corresponding extrusion groove 821 is increased, the inner wall of each extrusion groove 821 can push the corresponding movable part 72 close to the receiving piece 50 and attached to the receiving piece 50, and each movable part 72 can be deformed under the extrusion of the first connecting plate 42 and the second connecting plate 82. The movable part 72 attached to the receiving piece 50 can limit the movement of the receiving piece 50 in the vertical direction, at this time the height of the plurality of receiving pieces 50 can be kept fixed, and the support of the plurality of positions of the uneven side of the workpiece 200 is maintained, so that the receiving mechanism 101 is adapted to the specification of the workpiece 200. Then the worker can place the pressing plate 102 on the side of the workpiece 200 away from the receiving mechanism 101, and connect the pressing plate 102 with the receiving mechanism 101, so as to realize clamping of the workpiece 200.

[0081] It is apparent that a person skilled in the art can, without departing from the scope of the application, implement the application in other specific forms, and therefore the described embodiments should be considered as exemplary only and not limiting of the application, whose scope is defined by the claims appended hereinafter, rather than the description preceding it, which is therefore merely intended to provide an explanatory interpretation of the application.
