[0072] Some embodiments of the present application will be described in detail below with reference to the accompanying drawings.
[0073] See Figure 1 , the embodiment of the present application provides a clamping mechanism 100 for clamping a workpiece (not shown). The workpiece may be a tool or other object. For ease of understanding and explanation, the embodiment of the present application defines Figure 1 In the three-dimensional coordinate system shown, the X-axis is the first direction and the Y-axis is the second direction. It can be understood that this is not a limitation of the embodiments of the present application.
[0074] Please refer to Figure 2 The clamping mechanism 100 includes a base 10, a clamping assembly 20, a linkage assembly 30, and a drive assembly 40. The clamping assembly 20, the linkage assembly 30, and the drive assembly 40 are all disposed on the base 10. The drive assembly 40 drives the linkage assembly 30 to move, so that the linkage assembly 30 drives the clamping assembly 20 to clamp and release the workpiece.
[0075] Please refer to Figure 3 and Figure 4 The base 10 is provided with a plurality of accommodating grooves 11. Specifically, in this embodiment, the number of the accommodating grooves 11 is six, and the six accommodating grooves 11 are distributed in a 3*2 array along the first direction and the second direction. Each accommodating groove 11 includes a sliding groove 111, a accommodating hole 112 provided at the bottom of the sliding groove 111, a first push groove 114 provided at the inner groove wall 113 of the sliding groove 111, and a second push groove 116 provided at the outer groove wall 115 of the sliding groove 111. The inner groove wall 113 and the outer groove wall 115 are arranged opposite to each other. There are two first push grooves 114, and the two first push grooves 114 are arranged at intervals along the first direction. There are two second push grooves 116, and the two second push grooves 116 are arranged at intervals along the first direction. The structures of the first push groove 114 and the second push groove 116 are roughly the same.
[0076] In this embodiment, the base 10 is also provided with a linkage groove 12 and a sliding groove 13 for accommodating the sliding of the linkage assembly 30. The number of the linkage groove 12 is one and extends along the first direction. The number of the sliding grooves 13 is equal to the number of the accommodating grooves 11 and is connected one-to-one. Each sliding groove 13 extends along the second direction and is connected to the linkage groove 12.
[0077] It can be understood that in other embodiments, the number of accommodating grooves 11 and sliding grooves 13 can be more or less, for example, one, two, three or more, wherein more or fewer accommodating grooves 11 and sliding grooves 13 are arranged at intervals along the first direction on the base 10 and are all located on one side of the linkage groove 12, the number of linkage grooves 12 is one and the linkage groove 12 is adaptively extended or shortened along the first direction according to the number of accommodating grooves 11 and sliding grooves 13, and the number of clamping components 20 is multiple groups and is arranged one-to-one corresponding to the multiple accommodating grooves 11.
[0078] It can be understood that in other embodiments, the number of accommodating grooves 11 and sliding grooves 13 can also be multiple pairs, each pair of accommodating grooves 11 and sliding grooves 13 includes two accommodating grooves 11 and sliding grooves 13, and multiple pairs of accommodating grooves 11 and sliding grooves 13 are spaced apart along the first direction, and each pair of accommodating grooves 11 and sliding grooves 13 are respectively arranged on both sides of the linkage assembly 30 along the second direction, and the number of clamping assemblies 20 is multiple pairs and is arranged one-to-one corresponding to the multiple pairs of accommodating grooves 11.
[0079] Please refer to Figure 5The number of clamping assemblies 20 is equal to the number of receiving slots 11 and corresponds one to one. Each set of clamping assemblies 20 is disposed in a corresponding receiving slot 11. Each set of clamping assemblies 20 includes a first slide 21 and a second slide 22 disposed opposite each other. The first slide 21 of each set of clamping assemblies 20 is close to the linkage slot 12 and the linkage assembly 30. In this embodiment, each set of clamping assemblies 20 also includes an elastic member 23 disposed in the receiving slot 11 and abutting between the first slide 21 and the second slide 22. The elastic member 23 may be a spring. The number of elastic members 23 can be two, and the two elastic members 23 are spaced apart along the first direction and are both in contact with the first slide 21 and the second slide 22. The first slide 21 and the second slide 22 are both roughly T-shaped. The ends of the first slide 21 and the second slide 22 are both slidably arranged in the sliding groove 111 of the accommodating groove 11, and the middle parts of the first slide 21 and the second slide 22 are both located in the accommodating hole 112. The two ends of the elastic member 23 are respectively embedded in the first slide 21 and the second slide 22, and the elastic member 23 is located in the accommodating hole 112 to ensure that the elastic member 23 can stably abut against the first slide 21 and the second slide 22. A first clamping groove 212 is provided on the side of the first slide 21 facing the second slide 22, and a second clamping groove 222 is provided on the side of the second slide 22 facing the first slide 21. The first clamping groove 212 and the second clamping groove 222 cooperate to clamp the workpiece.
[0080] In this way, by setting the above-mentioned elastic member 23, when the linkage component 30 drives the first slide 21 and the second slide 22 to approach each other in the second direction in the accommodating groove 11 under the drive of the driving component 40, the elastic member 23 is compressed. When the linkage component 30 releases the first slide 21 and the second slide 22 under the drive of the driving component 40, the elastic force of the elastic member 23 is released to make the first slide 21 and the second slide 22 move away from each other in the second direction in the accommodating groove 11, so that the linkage component 30 only needs to drive the first slide 21 and the second slide 22 to approach each other in the second direction in the accommodating groove 11 under the drive of the driving component 40, which is beneficial to simplify the structure of the linkage component 30 and the driving component 40.
[0081] Please refer to Figure 6The linkage assembly 30 includes a linkage member 31, a first resisting member 32 and a second resisting member 33. The linkage member 31 is slidably arranged in the linkage groove 12 of the base 10 along the first direction and is spaced apart from the first slide 21. That is, the first slide 21 of each group of clamping assemblies 20 is close to the linkage member 31, and the first resisting member 32 and the second resisting member 33 are slidably arranged in the sliding groove 13 of the base 10. That is, the first resisting member 32 and the second resisting member 33 are respectively slidably arranged in the sliding groove 13 of the base 10 in a second direction perpendicular to the first direction, and the second resisting member 33 is arranged on the side of the first resisting member 32 away from the base 10. It can also be understood that the sliding directions of the first resisting member 32 and the second resisting member 33 are opposite, the first resisting member 32 is connected between the linkage member 31 and the first slide 21, and the second resisting member 33 is connected between the linkage member 31 and the second slide 22. In this embodiment, the number of the first push members 32 and the second push members 33 is three, and each first push member 32 and the second push member 33 corresponds to two accommodating grooves 11, two sliding grooves 13 and two groups of clamping components 20. The middle part of each first push member 32 is connected to the linkage member 31, one end of each first push member 32 is connected to the first slide 21 of one group of clamping components 20, and the other end of each first push member 32 is connected to the second slide 22 relative to the other group of clamping components 20. The middle part of each second push member 33 is connected to the linkage member 31, one end of each second push member 33 is connected to the second slide 22 of one group of clamping components 20, and the other end of each second push member 33 is connected to the first slide 21 relative to the other group of clamping components 20.
[0082] In this way, when the driving component 40 drives the linkage member 31 to move along the first direction, the linkage member 31 simultaneously drives the first push member 32 and the second push member 33 to slide in the opposite direction in the sliding groove 13 of the base 10 in the second direction, and the first push member 32 drives the first slide 21 of one group of clamping components 20 and the second slide 22 relative to the other group of clamping components 20 to move in the same direction and respectively approach or move away from the corresponding second slide 22 and the corresponding first slide 21, and the second push member 33 drives the second slide 22 of one group of clamping components 20 and the first slide 21 relative to the other group of clamping components 20 to move in the same direction and respectively approach or move away from the corresponding first slide 21 and the corresponding second slide 22, so that the first slide 21 and the second slide 22 of the two groups of clamping components 20 are away from or close to each other, so as to facilitate the placement or removal of materials between each group of first slide 21 and second slide 22, or to enable each group of first slide 21 and second slide 22 to clamp the workpiece.
[0083] In this embodiment, the linkage member 31 is disposed between the base 10 and the first resisting member 32, that is, the linkage member 31 is disposed below the first resisting member 32. The first resisting member 32 is provided with a first strip hole 322, and the second resisting member 33 is provided with a second strip hole 332. The first strip hole 322 is connected to the second strip hole 332, and the angle between the extension direction of the first strip hole 322 and the first direction can be 45°. The extension direction of the first strip hole 322 is perpendicular to the extension direction of the second strip hole 332. The linkage assembly 30 also includes a linkage portion 36 disposed on the side of the linkage member 31 facing the first resisting member 32 and inserted into the first strip hole 322 and the second strip hole 332. In this way, by setting the above-mentioned first strip hole 322, second strip hole 332 and linkage part 36, when the linkage part 31 moves in the first direction, the linkage part 31 cooperates with the linkage part 36, the first strip hole 322 and the second strip hole 332 to make the first push member 32 and the second push member 33 slide in opposite directions on the base 10 in the second direction.
[0084] It can be understood that in other embodiments, the linkage member 31 can also be located on the side of the second resisting member 33 away from the first resisting member 32, that is, the linkage member 31 is located above the second resisting member 33, and the linkage portion 36 is arranged on the side of the linkage member 31 facing the second resisting member 33; or, the linkage member 31 can also be located between the first resisting member 32 and the second resisting member 33, and the linkage portion 36 is arranged on both sides of the linkage member 31.
[0085] In this embodiment, the linkage assembly 30 also includes a first push portion 34 connected to the first push member 32 and extending toward the base 10 into the accommodating groove 11, and a second push portion 35 connected to the second push member 33 and extending toward the base 10 into the accommodating groove 11. The first push portion 34 abuts against the side of the first slide 21 facing away from the second slide 22, and the second push portion 35 abuts against the side of the second slide 22 facing away from the first slide 21. Among them, the number of the first pushing parts 34 and the second pushing parts 35 are both four, the first pushing part 32 and the second pushing part 33 are both roughly H-shaped, and the four first pushing parts 34 are respectively arranged at the four ends of the first pushing part 32, of which two first pushing parts 34 extend into the first pushing groove 114, and the other two first pushing parts 34 extend into the second pushing groove 116, and the four second pushing parts 35 are respectively arranged at the four ends of the second pushing part 33, of which two second pushing parts 35 extend into the second pushing groove 114, and the other two second pushing parts 35 extend into the first pushing groove 116. An avoidance hole 324 is provided at one end of the first pushing part 32 for connecting with the second sliding part 22 of another group of clamping components 20, and the first pushing part 32 avoids the corresponding second pushing part 35 on the second pushing part 33 through the avoidance hole 324.
[0086] In this way, by setting the above-mentioned first pushing portion 34 and second pushing portion 35, the first pushing member 32 pushes the first slide 21 of one group of clamping assemblies 20 through the first pushing portion 34, and pushes the second slide 22 of the other group of clamping assemblies 20 through the first pushing portion 34, and the second pushing member 33 pushes the second slide 22 of one group of clamping assemblies 20 through the second pushing portion 35, and pushes the first slide 21 of the other group of clamping assemblies 20 through the second pushing portion 35, thereby realizing the connection between the first pushing member 32 and the second pushing member 33 and the corresponding first slide 21 and the corresponding second slide 22 respectively, and simplifying the structure of the linkage assembly 30, so that the structure of the clamping mechanism 100 is compact.
[0087] It is understandable that in other embodiments, when a plurality of accommodating grooves 11 are only provided on the base 10 along the first direction, the structural adaptability of the first and second abutting members 32 and 33 changes, and the first and second abutting members 32 and 33 can both be roughly U-shaped.
[0088] Please refer to Figure 7 The driving assembly 40 is disposed on the base 10 and connected to the linkage member 31. The driving assembly 40 drives the linkage member 31 to move in the first direction, so that the linkage member 31 drives the first push member 32 and the second push member 33 to slide in opposite directions on the base 10 in the second direction, thereby causing the first slide member 21 and the second slide member 22 to move closer to or farther away from each other in the accommodating groove 11 in the second direction.
[0089] In this embodiment, the drive assembly 40 includes an assembly member 41 disposed on the base 10 and on the side of the linkage member 31 facing away from the base 10, a rotating member 42 rotatably disposed on the assembly member 41, an eccentric member 43 eccentrically connected to the rotating member 42, and a handle 44 connected to the rotating member 42. The handle 44 receives external force to drive the rotating member 42 and the eccentric member 43 to rotate. The assembly member 41 is spaced apart from the first and second thrust members 32 and 33 along a first direction, and the rotating member 42 can be a bearing. The linkage member 31 is provided with a guide hole 312 extending along a second direction, and the eccentric member 43 is inserted into the guide hole 312.
[0090] Thus, by setting the specific structure of the above-mentioned driving component 40, please refer to Figure 1When the handle 44 is rotated counterclockwise, the handle 44 drives the rotating member 42 to rotate counterclockwise, and the rotating member 42 drives the eccentric member 43 to rotate counterclockwise eccentrically. The eccentric member 43 drives the linkage member 31 to move in the first direction due to the eccentric rotation, and through the first push member 32 and the second push member 33, the first slide 21 and the second slide 22 are moved away from each other in the accommodating groove 11 in the second direction. When the handle 44 is rotated clockwise, the handle 44 drives the rotating member 42 to rotate clockwise, and the rotating member 42 drives the eccentric member 43 to rotate eccentrically clockwise. The eccentric member 43 drives the linkage member 31 to move in the first direction due to the eccentric rotation, and through the first push member 32 and the second push member 33, the first slide 21 and the second slide 22 are moved closer to each other in the accommodating groove 11 in the second direction.
[0091] It is understandable that in other embodiments, the driving assembly 40 may also be a linear cylinder or other functional structure that can be directly connected to the linkage member 31 and drive the linkage member 31 to perform linear reciprocating movement.
[0092] It is understandable that in other embodiments, the assembly 41 can also be a part of the base 10, and the assembly 41 is located above the linkage 31. In this way, the rotating member 42 can also be rotatably disposed on the base 10 and disposed on the side of the linkage 31 away from the base 10.
[0093] It is understandable that in other embodiments, the rotating member 42 may be driven to rotate by an external manipulator or other functional mechanism capable of driving the rotating member 42 to rotate. In this case, the handle 44 may be omitted.
[0094] In order to protect the clamping assembly 20, the linkage assembly 30, and the drive assembly 40 and prevent them from detaching from the base 10, in this embodiment, the clamping mechanism 100 further includes a cover plate 50, which is connected to the base 10. The clamping assembly 20, the linkage assembly 30, and the drive assembly 40 are all arranged between the cover plate 50 and the base 10. The cover plate 50 is provided with discharge holes 51 corresponding to the receiving grooves 11, and the number of discharge holes 51 is equal to the number of receiving grooves 11. Specifically, the cover plate 50 includes a cover body 52, an edge 53, and a plurality of screws 54. The edge 53 is annular, connected to the circumference of the cover body 52 and extending to the circumference of the base 10. The plurality of screws 54 are spaced apart on the edge 53, and each screw 54 passes through the edge 53 and is connected to the base 10, thereby achieving the connection between the cover plate 50 and the base 10. In this way, by setting the above-mentioned cover plate 50 and the specific structure of the cover plate 50, the clamping assembly 20, the linkage assembly 30 and the driving assembly 40 are protected to prevent the clamping assembly 20, the linkage assembly 30 and the driving assembly 40 from detaching from the base 10, thereby ensuring the stability of the clamping mechanism 100.
[0095] When the above-mentioned clamping mechanism 100 is clamping a workpiece, the driving component 40 drives the linkage member 31 to move in the first direction, so that the linkage member 31 drives the first push member 32 and the second push member 33 to slide in the opposite direction on the base 10 in the second direction, thereby causing the first slide 21 and the second slide 22 to move away from each other in the accommodating groove 11 in the second direction, so as to place the workpiece between the first slide 21 and the second slide 22 or take out the processed workpiece from between the first slide 21 and the second slide 22. When the first slide 21 and the second slide 22 move away from each other in the accommodating groove 11 in the second direction, the workpiece is placed between the first slide 21 and the second slide 22, and the driving component 40 drives the linkage member 31 to move in the opposite direction in the first direction, so that the linkage member 31 drives the first push member 32 and the second push member 33 to slide in the opposite direction in the second direction, thereby causing the first slide 21 and the second slide 22 to move closer to each other in the accommodating groove 11 in the second direction to clamp the workpiece, thereby realizing efficient clamping of the workpiece.
[0096] The clamping mechanism 100 provided in the embodiment of the present application realizes efficient clamping of the workpiece through the coordinated cooperation of the base 10, the clamping assembly 20, the linkage assembly 30 and the drive assembly 40; the first slide 21 and the second slide 22 are close to each other in the accommodating groove 11 in the second direction to clamp the workpiece, ensuring that the first slide 21 and the second slide 22 can accurately clamp the workpiece, which is conducive to improving the processing accuracy of the workpiece; the first slide 21 and the second slide 22 are highly versatile and can meet the clamping requirements of workpieces of different shapes and sizes; the workpiece can be clamped by the drive assembly 40, and the clamping mechanism 100 can be applied to an automated production line, which is conducive to realizing unmanned or less-manned production, reducing the investment in equipment and human resources, and reducing production costs. The clamping mechanism 100 provided in the embodiment of the present application further protects the clamping assembly 20, the linkage assembly 30 and the drive assembly 40 through the cover plate 50, preventing the clamping assembly 20, the linkage assembly 30 and the drive assembly 40 from detaching from the base 10, thereby ensuring the stability of the clamping mechanism 100.
