Detailed Implementation

[0024] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments:

[0025] In the description of this utility model, it should be noted that the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0026] 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 invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0027] like Figure 1-5 The illustrated clamping jig includes an assembly base 10 and an assembly positioning block 20. The assembly base 10 has a clamping positioning groove 11 for clamping a clamping arm 30 and a clamping jaw 40. A first positioning magnet 15 is located at the bottom of the assembly base 10, and the first positioning magnet 15 magnetically attracts the clamping jaw 40. The assembly positioning block 20 is connected to the top of the assembly base 10, and after being connected to the top of the assembly base 10, the assembly positioning block 20 can cover the top of the positioning groove 11. The assembly positioning block 20 has a second positioning magnet 21, which magnetically attracts the top of the clamping arm 30.

[0028] Based on the above structure, when using the coplanar assembly fixture of the present invention, since the existing technology generally includes a gripper arm 30 connected to the drive component and a gripper 40 for clamping the workpiece, the gripper arm 30 and the gripper 40 are assembled by connecting parts such as screws or bolts during clamping.

[0029] During assembly, the gripper arm 30 and gripper 40 are pre-installed and placed in the clamping positioning groove 11, allowing for positioning by the positioning groove 11. Then, the assembly positioning block 20 is connected to the assembly base 10. The assembly positioning block 20 can cover the top of the clamping positioning groove 11, allowing the first positioning magnet 15 at the bottom of the assembly base 10 to magnetically attract the bottom of the gripper 40, so that the bottom of the gripper 40 fits against the bottom surface of the positioning groove 11. Simultaneously, the second positioning magnet 15 on the assembly positioning block 20 at the top of the positioning groove 11... The magnet 21 can be magnetically attracted to the top of the gripper arm 30 so that the top of the gripper arm 30 is attached to the bottom surface of the assembly positioning block 20. In this way, the gripper arm 30 is positioned by the second positioning magnet 21 on the top, and the gripper 40 is positioned by the first positioning magnet 15 on the bottom. Therefore, the two sets of gripper arms 30 and the gripper 40 can be assembled under the action of the first positioning magnet 15 and the second positioning magnet 21, and the clamping surface of the gripper 40 remains on a uniform plane after assembly, resulting in higher clamping accuracy.

[0030] Furthermore, in order to better assemble the first positioning magnet 15, a first magnet groove 16 can be provided on the assembly base 10. The first positioning magnet 15 is installed in the first magnet groove 16, which can realize the positioning assembly of the first positioning magnet 15. The assembly position of the first positioning magnet 15 is limited by the first magnet groove 16. The position accuracy of the first positioning magnet 15 installed in this way is high, so the adsorption and positioning accuracy of the gripper 40 is high, and the coplanarity of the gripper 40 after assembly is higher.

[0031] Furthermore, the assembly positioning block 20 is provided with a second magnet slot, and the second positioning magnet 21 is installed in the second magnet slot. This enables the positioning and assembly of the second positioning magnet 21. The assembly position of the second positioning magnet 21 is limited by the second magnet slot, resulting in high positional accuracy of the installed second positioning magnet 21. Therefore, the adsorption and positioning accuracy of the gripper arm 30 is high, and the coplanarity of the gripper arm 30 after assembly is higher.

[0032] Furthermore, the aforementioned assembly base 10 has opposing first and second sides, and the side of the aforementioned positioning groove 11 extends to the first and / or second sides. In this embodiment, the first and second sides refer to the front and rear sides of the assembly base 10. For example, the front side of the positioning groove 11 extends to the front side. After the gripper arm 30 and gripper 40 are positioned by the magnetic attraction of the corresponding magnet, screws or bolts can be inserted into the front side of the positioning groove 11 so that the gripper arm 30 and gripper 40 can be clamped in the positioning groove 11.

[0033] Alternatively, the rear side of the positioning groove 11 can be connected to the rear side. After the gripper arm 30 and gripper 40 are positioned by the magnetic attraction of the corresponding magnet, screws or bolts can be installed from the rear side of the positioning groove 11 so that the gripper arm 30 and gripper 40 can be clamped in the positioning groove 11.

[0034] Of course, the front and rear sides of the positioning groove 11 can be connected to the front and rear sides of the assembly base 10, so that the gripper arm 30 and gripper 40 do not need to be inserted into the corresponding through surface after being installed, thus improving the assembly efficiency.

[0035] Furthermore, a positioning piece 111 is provided in the positioning groove 11, which divides the positioning groove 11 into two positioning groove segments 11. In this way, the two sets of gripper arms 30 and grippers 40 of the gripper 40 structure can be placed into the two positioning groove segments 11 separated by the positioning piece 111, thus reducing interference during the clamping process. Based on this structure, the first positioning magnet 15 is set in the middle position of the positioning groove 11 and is set corresponding to the bottom wall of the two positioning groove segments 11. The second positioning magnet 21 can also be set in the middle position of the assembly positioning block 20. After assembly, the second positioning magnet 21 is located in the middle position of the top of the positioning groove 11. The two sets of gripper arms 30 and grippers 40 are positioned coplanarly with the same first positioning magnet 15 and second positioning magnet 21.

[0036] Furthermore, a first connecting hole 22 can be provided on the assembly positioning block 20, and a second connecting hole 13 can be provided on the assembly base 10. The first connecting hole 22 and the second connecting hole 13 correspond to each other and are used to pass through connecting parts. In this way, when the assembly positioning block 20 is connected to the assembly base 10, the first connecting hole 22 and the second connecting hole 13 correspond to each other, and then a detachable connection can be achieved with connecting parts such as screws and bolts, which makes assembly convenient.

[0037] Furthermore, the assembly positioning block 20 is provided with a positioning step 12, which is located on both sides of the opening of the positioning groove 11. The positioning step 12 can be used to abut against the step structure at the top of the gripper arm 30.

[0038] Furthermore, the side of the assembly base 10 is also provided with a positioning through hole 14, which extends to the positioning groove 11. In this embodiment, the positioning through hole 14 can be located on the left and right sides of the assembly base 10. After being positioned by the magnetic attraction of the positioning magnets at the top and bottom, a positioning rod or other structure can be inserted into the positioning through hole 14 to the positioning groove 11 to position the gripper arm 30 and the gripper 40 at the middle position.

[0039] For those skilled in the art, various other corresponding changes and modifications can be made based on the technical solutions and concepts described above, and all such changes and modifications should fall within the protection scope of the claims of this utility model.
