The left-side positioning and bearing mechanism includes a slide rail, a slide block, a support frame, a limiting rod, a bearing plate, a three-jaw chuck, and multiple clamping cylinders. The slide rail is fixed to the base plate along its length. The slide block is slidably connected to the slide rail. The support frame is fixed to the slide block. One side of the bottom end of the bearing plate is rotatably connected to the support frame. The limiting rods are located on both sides of the bearing plate and fixed to the support frame. The three-jaw chuck is rotatably connected to the bearing plate. The multiple clamping cylinders are respectively fixed to both sides of the bearing plate.

[0007] The right-side fine-tuning mechanism includes a worm gear screw jack, a lifting seat, a Y-axis linear slide, a base, and multiple push-pull quick clamps. The worm gear screw jack is fixed to the base plate, the lifting seat is fixed to the top of the worm gear screw jack and is driven to lift by the worm gear screw jack, the Y-axis linear slide is mounted on the lifting seat, the base is fixed to the slide of the Y-axis linear slide, and the surface of the base is provided with a placement groove. Multiple push-pull quick clamps are installed around the placement groove.

[0008] An adjustment channel is formed between the limiting rods on both sides, and the bearing plate can rotate within the adjustment channel.

[0009] The three-jaw chuck is a pneumatic three-jaw chuck.

[0010] Rubber pads are fixed on the grippers of the clamping cylinder.

[0011] To facilitate manual adjustment by staff, a hand crank is installed on the worm gear screw jack, and a hand crank is also fixed to the end of the screw in the Y-axis linear slide.

[0012] In summary, this application includes at least one of the following beneficial technical effects: the auxiliary docking device for assembling a robotic arm fixes the robotic arm cantilever by setting a left positioning and bearing mechanism and a right fine-tuning mechanism to fix the robotic arm base. Then, only the left positioning and bearing mechanism and the right fine-tuning mechanism need to be adjusted to achieve docking between the robotic arm cantilever and the robotic arm base. The two dock in a relatively static state, which is convenient, efficient, safe and reliable. Attached Figure Description

[0017] The following is in conjunction with the appendix Figure 2-3 This application will be described in further detail.

[0018] This application discloses an auxiliary docking device for assembling a robotic arm, referring to... Figure 2-3The system includes a base plate 1, on which a left positioning bearing mechanism 2 and a right fine-tuning mechanism 3 are provided. The left positioning bearing mechanism 2 includes a slide rail 21, a slide seat 22, a support frame 23, a limiting rod 24, a bearing plate 25, a three-jaw chuck 26, and multiple clamping cylinders 27. The slide rail 21 is fixed on the base plate 1 along its length. The slide seat 22 is slidably connected to the slide rail 21. The support frame 23 is fixed on the slide seat 22. The bottom end of the bearing plate 25 is rotatably connected to the side of the support frame 23. The limiting rods 24 are provided on both sides of the bearing plate 25 and fixed on the support frame 23. An adjustment channel is formed between the two limiting rods 24, allowing the bearing plate 25 to rotate within the adjustment channel. The three-jaw chuck 26 is rotatably connected to the bearing plate 25. The three-jaw chuck 26 is a pneumatic three-jaw chuck 26. Multiple clamping cylinders 27 are respectively fixed on both sides of the bearing plate 25. Rubber pads are fixed on the jaws of the clamping cylinders 27.

[0019] The right-side fine-tuning mechanism 3 includes a worm gear screw jack 31, a lifting seat 32, a Y-axis linear slide 33, a base 34, and multiple push-pull quick clamps 35. The worm gear screw jack 31 is fixed on the base plate 1. The lifting seat 32 is fixed on the top of the worm gear screw jack 31 and is driven to lift by the worm gear screw jack 31. The Y-axis linear slide 33 is installed on the lifting seat 32. The base 34 is fixed on the slide of the Y-axis linear slide 33. The surface of the base 34 is provided with a placement groove, and multiple push-pull quick clamps 35 are installed around the placement groove.

[0020] To facilitate manual adjustment by staff, a hand crank is installed on the worm gear screw jack 31, and a hand crank is also fixed to the end of the screw in the Y-axis linear slide 33.

[0021] The implementation principle of the auxiliary docking device for robot assembly in this application is as follows:

[0022] In use, first, the robot arm base is suspended in the placement slot of the right-side fine-tuning mechanism 3 and clamped by multiple push-pull quick clamps 35. Then, the robot arm cantilever is suspended to the side of the left-side positioning bearing mechanism 2 and aligned with the insertion of the three-jaw chuck 26. The three-jaw chuck 26 clamps the robot arm through the through hole at the bottom of the robot arm. Multiple clamping cylinders 27 clamp the robot arm cantilever onto the bearing plate 25. After that, the operator can assemble it. During assembly, push the support frame 23 to move the robot arm cantilever closer to the robot arm base. Adjust the position of the robot arm base by using the worm gear screw jack 31 and the Y-axis linear slide 33 so that the screw holes on the robot arm base are aligned with the screw holes on the robot arm cantilever. The bearing plate 25 can be rotated to make the screw holes on the robot arm cantilever completely aligned with the screw holes on the robot arm base. Finally, install the bolts. The whole installation process is easy to operate and has high docking efficiency.

[0023] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
