It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0027] A coupling positioning assembly tool, please refer to Figure 1-4 , including a base 1, a clamping seat 2 slidably connected to the base 1, and a propulsion mechanism 3 for driving the clamping seat 2 to slide horizontally on the base 1.

[0028] Two parallel slide rails 11 are arranged on the base 1, the clamping seat 2 includes a frame 25, and sliders 26 fixed on both sides below the frame 25 and slidably connected to the slide rails 11, a screw nut 33 is fixed under the frame 25, the propulsion mechanism 3 includes a motor 31 fixed on the base 1, the output end of the motor 31 is coaxially fixedly connected with a screw 32, the screw 32 is threadedly connected with the screw nut 33, when the motor 31 rotates, it drives the screw 32 to rotate, the screw 32 drives the screw nut 33 to move along the axial direction of the screw 32, the screw nut 33 can drive the clamping seat 2 to move, so that the coupling fixed on the clamping seat 2 is close to the assembly position, it has good stability, and provides the accuracy of positioning and assembly.

[0029] The clamping seat 2 includes at least one claw plate 21 for clamping the coupling, and vertical through grooves 251 are relatively opened on both sides of the frame 25. Limiting slides 27 are fixedly connected to both sides of the claw plate 21, and the limiting slides 27 are slidably connected to the through grooves 251. A cylinder 4 is fixed on the frame 25, and the telescopic end of the cylinder 4 is fixedly connected to the bottom of the claw plate 21 and can be telescopic to drive the claw plate 21 to rise and fall in the vertical direction; the motor 31 rotates to drive the screw rod 32 to rotate, and the screw rod nut 33 moves, so that the claw plate 21 can be driven to move in the horizontal direction to adjust the position. The extension and contraction of the cylinder 4 can drive the claw plate 21 to move in the vertical direction to adjust the position, thereby realizing the adjustability of the position of the claw plate 21 in the horizontal and vertical directions, and improving the assembly accuracy and assembly speed of the coupling.

[0030] The middle part of the claw plate 21 has a through hole 211 for the coupling to extend into, and a plurality of positioning claws 22 and a plurality of stabilizing claws 23 are evenly arranged around the through hole 211. The stabilizing claws 23 and the positioning claws 22 are arranged one by one. The stabilizing claws 23 include a connecting block 231 for connecting with the claw plate 21, and an elastic pad 232. A groove 2311 is formed at one end of the top surface of the connecting block 231 facing inward, and the elastic pad 232 is fixed in the groove 2311 by screws.

The diameter of the through hole 211 on the claw plate 21 is slightly larger than the virtual circumference. The elastic pad 232 at least partially extends into the above-mentioned virtual circle, and the extension length is 2-3mm, so that the coupling can achieve an interference fit when inserted;

[0032] When assembling the coupling, the tail end of the coupling is inserted through the positioning claw 22 and extended into the through hole 211. The inner wall of the positioning claw 22 and the inner wall of the connecting block 231 fit the outer wall of the coupling. At the same time, the elastic pad 232 is compressed and tightly attached to the outer wall of the coupling, limiting the freedom of rotation and axial movement of the coupling. The cylinder 4 is extended and retracted to drive the claw plate 21 to move until the coupling is coaxially opposite to the assembly station. The motor 31 rotates to drive the claw plate 21 to move horizontally toward the assembly station to assemble the coupling. After the coupling is assembled, the motor 31 is reversed to move the clamping seat 2 away from the assembly position, so that the claw plate 21 can be disengaged from the coupling, and the coupling is inserted into the through hole 211 for the next assembly, thereby improving the speed of streamlined assembly.

[0033] A column 24 is fixed on the surface of the claw plate 21, and the end face of the column 24 is provided with a first protrusion 241 and a first recessed portion 242. The bottom face of the connecting block 231 is provided with a second protrusion and a second recessed portion 2313. The first protrusion 241 and the second recessed portion 2313 are interlocked with each other, and the second protrusion 2312 and the first recessed portion 242 are interlocked with each other. The first protrusion 241 and the first recessed portion 242 are cross-arranged in a cross shape to improve the stability of the connection between the stabilizing claw 23 and the claw plate 21. The connecting block 231 is fixed to the column 24 by bolts. The stabilizing claw 23 can be disassembled and assembled, and the elastic pad 232 can be replaced.
