For ease of understanding and explanation, the present embodiment defines the first direction as Figure 1 and Figure 2 The Z-axis direction is shown, and the second direction is Figure 1 and Figure 2 In the Y-axis direction shown, the first direction and the second direction are perpendicular to each other. Obviously, this is not a limitation of the embodiments of the present application.

[0060] See also Figure 1 and Figure 2 In this embodiment, the clamping mechanism 100 includes a base 10, a covering assembly 20, a sliding member 30, a clamping elastic member 40 and a locking member 50.

[0061] The covering assembly 20 is movably covered on the base 10 along a first direction.

[0062] The two ends of the clamping elastic member 40 are connected to the sliding member 30 and the covering assembly 20 respectively; the locking member 50 is arranged on the side of the base 10 facing the covering assembly 20 and facing the avoidance hole 211, and the end of the locking member 50 away from the base 10 is provided with a clamping groove 51 for clamping with the sliding member 30, and the locking member 50 is used to pass through the avoidance hole 211 and squeeze the abutting inclined surface 31, so that the sliding member 30 compresses the clamping elastic member 40, and the clamping elastic member 40 is used to drive the sliding member 30 to clamp with the clamping groove 51 when the sliding member 30 faces the clamping groove 51, so as to limit the covering assembly 20 from being separated from the base 10. Specifically, the avoidance hole 211 is provided on the side of the covering assembly 20 facing the base 10, the clamping elastic member 40 can be a spring, and the angle between the abutting inclined surface 31 and the plane where the X-axis direction and the Z-axis direction are located is an acute angle.

The locking member 50 passes through the avoidance hole 211 and compresses the sliding member 30 by squeezing the abutment slope 31 to compress the elastic member 40. When the locking member 50 continues to pass through the avoidance hole 211 and the slot 51 is directly opposite to the sliding member 30, the elastic member 40 drives the sliding member 30 to engage with the slot 51 to lock the covering assembly 20 and the base 10. At this time, the covering assembly 20 and the base 10 cooperate to lock the product.

[0064] See also Figure 1 , Figure 2 and Figure 3In this embodiment, the cover assembly 20 includes a cover pressing member 21 and a guide member 22. The cover pressing member 21 is movably covered on the base 10 along the first direction, and the avoidance hole 211 is provided in the cover pressing member 21, and the avoidance hole 211 is a through hole.

When assembling the covering component 20, the sliding member 30 and the snap-in elastic member 40, it is only necessary to connect the snap-in elastic member 40 with the sliding member 30 and the side wall of the limiting notch 212, and then install the guide member 22 in the limiting notch 212 and make the sliding member 30 located in the slide groove 221, which is beneficial to improve the convenience of assembling the covering component 20, the sliding member 30 and the snap-in elastic member 40; in addition, by setting the limiting notch 212 to limit the guide member 22, it is beneficial to improve the accuracy of installing the guide member 22, and after the guide member 22 is set in the limiting notch 212, the sliding member 30 and the snap-in elastic member 40 are both located in the limiting notch 212, which is beneficial to improve the compactness of the structure after the covering component 20, the sliding member 30 and the snap-in elastic member 40 are assembled.

[0065] In some other embodiments, the cover pressing member 21 and the guide member 22 may also be an integral structure, which is not specifically limited in the embodiments of the present application.

[0066] In this embodiment, the guide member 22 is also provided with a connecting hole 222, and the bottom of the limiting notch 212 is provided with an assembly hole 214. The connecting hole 222 and the connecting hole 222 can both be threaded holes. The cover assembly 20 also includes a connecting member 23, and the connecting member 23 can be a bolt. The connecting member 23 passes through the connecting hole 222 and is inserted into the assembly hole 214 to connect the guide member 22 and the cover pressing member 21, thereby facilitating the convenience of assembling the guide member 22 and the cover pressing member 21.

[0067] In this embodiment, the cover assembly 20 further includes a positioning pin 24, which is inserted into the bottom of the limiting notch 212 along the first direction, and a positioning hole 223 is provided on the side of the guide member 22 facing the cover pressing member 21, and the positioning pin 24 is inserted into the positioning hole 223 to position the guide member 22. By inserting the positioning pin 24 into the positioning hole 223 to position the guide member 22, it is helpful to improve the accuracy of the assembly of the guide member 22 and the cover pressing member 21.

[0068] In this embodiment, the number of avoidance holes 211, slide grooves 221, sliding parts 30, snap-on elastic parts 40 and locking parts 50 are all multiple, and the multiple avoidance holes 211 are spaced apart and arranged in a rectangular shape. The multiple slide grooves 221 are respectively opposite to and connected with the multiple avoidance holes 211, and the multiple sliding parts 30 are respectively slidably arranged in the corresponding slide grooves 221. The two ends of the multiple snap-on elastic parts 40 are respectively connected to the cover assembly 20 and the corresponding sliding parts 30, and the multiple locking parts 50 are spaced apart on the side of the base 10 facing the cover assembly 20 and are respectively opposite to the multiple avoidance holes 211. Specifically, the cover pressing member 21 is a rectangular parallelepiped structure, the limiting notches 212 are multiple and are respectively opened at the top corner positions of the side of the cover pressing member 21 away from the base 10, the multiple avoidance holes 211 are respectively connected to the multiple limiting notches 212, the number of guide members 22 is also multiple, the multiple guide members 22 are respectively set in the corresponding limiting notches 212, the multiple sliding members 30 are respectively slidably set in the sliding grooves 221 opened in the corresponding guide members 22, and the two ends of the multiple clamping elastic members 40 are respectively connected to the corresponding sliding members 30 and the side walls of the corresponding limiting notches 212. In this way, the multiple locking members 50 can cooperate with the multiple sliding members 30 and the multiple clamping elastic members 40 to lock the base 10 and the cover assembly 20 at multiple positions, which is conducive to improving the stability of the clamping mechanism 100 locking the product.

[0069] Please refer to Figure 4 In this embodiment, a first limiting hole 213 is provided on the side wall of the limiting notch 212 facing the snap-in elastic member 40, and a second limiting hole 36 facing the first limiting hole 213 is provided on the sliding member 30. Both ends of the snap-in elastic member 40 are respectively inserted into the first limiting hole 213 and the second limiting hole 36. The first limiting hole 213 and the second limiting hole 36 can position the snap-in elastic member 40 and limit the lateral movement of the snap-in elastic member 40 during extension and contraction, thereby facilitating improving the accuracy of the snap-in elastic member 40 driving the sliding member 30 to move.

[0070] In this embodiment, the sliding member 30 is provided with an insertion hole 32 extending along the first direction and directly facing the avoidance hole 211, and an abutting protrusion 33 is convexly provided on the inner wall of the insertion hole 32, and the abutting inclined surface 31 is arranged on the abutting protrusion 33. Specifically, the abutting protrusion 33 is wedge-shaped and is located at the end of the insertion hole 32 away from the base 10. When the covering assembly 20 is covered on the base 10, the locking member 50 passes through the avoidance hole 211 and is inserted into the insertion hole 32 to abut against the abutting inclined surface 31, and the insertion hole 32 limits the locking member 50, thereby facilitating the accuracy of the locking member 50 abutting and pressing the abutting inclined surface 31.

[0071] In some other embodiments, the sliding member 30 may not have the insertion hole 32, the abutment protrusion 33 may be set at the end of the sliding member 30 away from the locking elastic member 40 and the abutment slope 31 is located on the abutment protrusion 33, and the locking member 50 can also compress the locking elastic member 40 by squeezing the abutment slope 31. The embodiment of the present application does not make any specific limitations on this.

[0072] In this embodiment, a first limiting protrusion 34 is convexly provided on the side of the sliding member 30 away from the base 10, and the first limiting protrusion 34 is located on the side of the insertion hole 32 close to the clamping elastic member 40; the covering assembly 20 also has a stopper 226 extending to the slide groove 221, and the stopper 226 is arranged on the side of the first limiting protrusion 34 away from the clamping elastic member 40. When the abutting inclined surface 31 is directly opposite to the avoidance hole 211, the stopper 226 stops the first limiting protrusion 34 to limit the sliding member 30 and the first limiting protrusion 34 from continuing to move, thereby facilitating improving the accuracy of the abutting inclined surface 31 and the avoidance hole 211 being directly opposite to each other. In addition, the stopper 226 cooperates with the first limiting protrusion 34 to limit the sliding member 30 from escaping from the slide groove 221 along the second direction.

[0073] In this embodiment, a second limiting protrusion 35 is also provided on the side of the sliding member 30 away from the base 10. The second limiting protrusion 35 is located on the side of the insertion hole 32 away from the first limiting protrusion 34, and the second limiting protrusion 35 is spaced apart from the first limiting protrusion 34. The opposite side walls of the slide groove 221 are respectively provided with a first stop protrusion 224 and a second stop protrusion 225 close to each other. The two ends of the stopper 226 are respectively connected to the first stop protrusion 224 and the second stop protrusion 225. The first stop protrusion 224 and the second stop protrusion 225 are used to stop the second limiting protrusion 35 to limit the distance that the sliding member 30 moves toward the clamping elastic member 40. When the product processing is completed and the cover assembly 20 and the base 10 need to be opened, the sliding member 30 can be pushed by the manipulator to move toward the clamping elastic member 40. At this time, the clamping elastic member 40 is compressed, and the sliding member 30 is disengaged from the clamping groove 51, so that the cover assembly 20 and the base 10 can be opened. By setting the second limit protrusion 35 to cooperate with the first stop protrusion 224 and the second stop protrusion 225 to limit the distance that the sliding member 30 moves toward the locking elastic member 40, the sliding member 30 can be accurately moved to the unlocking position under the action of external force, thereby effectively preventing the sliding member 30 from moving too much and causing the inner wall of the insertion hole 32 to squeeze the locking member 50, making it difficult to pull the locking member 50 out of the insertion hole 32, and reducing the probability of damaging the locking member 50.

[0074] In this embodiment, the first stop protrusion 224 and the second stop protrusion 225 are both roughly in the shape of a cuboid, the stop portion 226 is rod-shaped, and the length of the first limit protrusion 34 is less than or equal to the distance between the first stop protrusion 224 and the second stop protrusion 225. When the engaging elastic member 40 drives the sliding member 30 to move along the slide groove 221, the first limit protrusion 34 moves between the first stop protrusion 224 and the second stop protrusion 225, and the first stop protrusion 224 and the second stop protrusion 225 limit the moving direction of the first limit protrusion 34, thereby facilitating the improvement of the sliding accuracy of the sliding member 30 in the slide groove 221.

[0075] In this embodiment, the first stop protrusion 224 and the second stop protrusion 225 have a guide inclined surface 2241 (such as a guide surface 2242) for contacting with the first limit protrusion 34 at one end thereof close to the first limit protrusion 34. Figure 3 By providing the guiding inclined surface 2241, the first limiting protrusion 34 can be guided when the first limiting protrusion 34 moves between the first stop protrusion 224 and the second stop protrusion 225, so that the first limiting protrusion 34 can be quickly moved between the first stop protrusion 224 and the second stop protrusion 225 to face the stop portion 226.

[0076] In this embodiment, the slide groove 221 is connected to the side of the guide member 22 away from the cover pressing member 21, and the first stop protrusion 224 and the second stop protrusion 225 are flush with the side of the guide member 22 away from the cover pressing member 21, thereby facilitating the processing of the slide groove 221, the first stop protrusion 224, the second stop protrusion 225 and the stop portion 226, and facilitating the observation of the position of the sliding member 30.

[0077] In some other embodiments, the slide groove 221 may not be connected to the side of the guide member 22 facing away from the cover pressing member 21, and the first stop protrusion 224, the second stop protrusion 225 and the stop portion 226 are arranged at a position close to the bottom of the slide groove 221, and the embodiment of the present application does not make any specific limitation on this.

[0078] Please refer again Figure 2 In this embodiment, the end of the locking member 50 away from the base 10 has a guide portion 52, which is located on the side of the slot 51 away from the base 10, and the cross-sectional size of the guide portion 52 gradually decreases in the direction away from the base 10. By providing the guide portion 52, it is convenient to quickly insert the locking member 50 into the avoidance hole 211 when the covering assembly 20 is pressed on the base 10.

[0079] In this embodiment, the guide portion 52 has a pushing inclined surface 53 directly opposite to the abutting inclined surface 31. When the locking member 50 presses the abutting inclined surface 31, the locking member 50 presses the abutting inclined surface 31 through the pushing inclined surface 53 so that the sliding member 30 is compressed and engaged with the elastic member 40. The abutting inclined surface 31 and the pushing inclined surface 53 cooperate to improve the accuracy and stability of the locking member 50 pushing the sliding member 30 to move.

[0080] In this embodiment, a mounting hole 11 facing the avoidance hole 211 is provided on the side of the base 10 facing the cover assembly 20, and a through hole 12 and a fixing hole 13 communicating with the mounting hole 11 and arranged at intervals are provided on the side wall of the base 10. The locking member 50 is inserted into the mounting hole 11, and a limiting hole 54 is provided at one end of the locking member 50 inserted into the mounting hole 11. The clamping mechanism 100 further includes a limit pin 60 and an assembly member 70. The limit pin 60 passes through the through hole 12 and is inserted into the limiting hole 54 to limit the position of the locking member 50 inserted into the mounting hole 11. The assembly member 70 may be a locking bolt. The assembly member 70 passes through the fixing hole 13 and presses the locking member 50 into the mounting hole 11, so that the locking member 50 can be easily disassembled and assembled.

[0081] In some other embodiments, the locking member 50 may also be an integral structure with the base 10, which is not specifically limited in the embodiments of the present application.

[0082] In summary, the clamping mechanism 100 of the embodiment of the present application is provided with matching sliding members 30, clamping elastic members 40 and locking members 50. When locking a product, it is only necessary to apply force to the cover assembly 20 to move the cover assembly 20 toward the base 10, and the locking member 50 can compress the sliding member 30 by pressing the abutting inclined surface 31 to compress the clamping elastic member 40, and then the clamping elastic member 40 drives the sliding member 30 to clamp with the clamping groove 51 so that the cover assembly 20 and the base 10 lock the product. In this way, the clamping mechanism 100 of the embodiment of the present application is convenient for locking products by automated means, which improves the efficiency of locking products and reduces labor costs.
