Description

Technical Field

[0001] This utility model belongs to the field of disassembly and maintenance technology of robotic arms, and particularly relates to an auxiliary device for disassembling robotic arm components. Background Technology

[0002] In industrial production, robotic arms are widely used to complete material handling and manufacturing on production lines, especially in automotive parts manufacturing companies where they are indispensable in fast-paced production processes. However, in today's enterprises, the robotic arms used for material handling and manufacturing experience wear and tear on their five- and six-axis wrists due to the working environment, which can lead to oil leaks.

[0003] Wear and tear on five- or six-axis wrist straps can affect on-site production and use. Repairing five- or six-axis wrist straps is not only time-consuming and labor-intensive, but also increases unnecessary costs for enterprises. Due to the instability of disassembling and assembling five- or six-axis wrist straps manually, the disassembly and assembly effect is greatly reduced, and it is difficult to achieve the required clearance fit, making standardization impossible.

[0004] Therefore, there is an urgent need to design an auxiliary device for disassembling robotic arm components to solve the problems mentioned above. Utility Model Content

[0005] To address the technical problem mentioned in the background art of instability in the disassembly and assembly of five- or six-axis wrists by a single operator, which greatly reduces the disassembly and assembly efficiency of five- or six-axis wrists, an auxiliary device for disassembling robotic arm components is provided to solve the problem of disassembly and assembly difficulties caused by the complexity of five- or six-axis wrists.

[0006] To achieve the above objectives, the specific technical solution of the auxiliary device for disassembling robotic arm components according to this utility model is as follows:

[0007] An auxiliary device for disassembling robotic arm components includes a table frame and a tabletop. The tabletop is mounted on the table frame, and a first connecting seat and a second connecting seat are spaced apart on the tabletop. A screw is rotatably mounted between the first and second connecting seats. The screw drives a first force-bearing seat to slide along the length of the tabletop. A second force-bearing seat is mounted on the tabletop, and a five- or six-axis wrist to be disassembled is mounted on the second force-bearing seat. By rotating the screw, a push rod mounted on the first force-bearing seat moves closer to or further away from the five- or six-axis wrist to be disassembled, so that the push rod pushes out the six-axis component of the five- or six-axis wrist.

[0008] Furthermore, the first connecting seat and the second connecting seat are fixedly connected to both ends of the table, and the two ends of the screw are rotatably connected to the first connecting seat and the second connecting seat, respectively.

[0009] Furthermore, a slider is screwed onto the screw, and a first force-bearing seat is fixedly connected to the slider so that the first force-bearing seat can slide.

[0010] Furthermore, two slide rails are spaced apart along the length of the tabletop so that the slider can be slidably mounted on the slide rails.

[0011] Furthermore, a second force-bearing seat is fixedly connected to the end of the table away from the first force-bearing seat. Rotating the screw drives the first force-bearing seat to move towards the second force-bearing seat, so that the push rod pushes out the sixth axis of the five-six axis wrist.

[0012] Furthermore, the second force-bearing seat is provided with a first clamping block and a second clamping block, so that the first clamping block and the second clamping block can clamp the five- or six-axis wrist to be disassembled.

[0013] Furthermore, the first connecting seat and the second connecting seat are respectively provided with shaft seats so that both ends of the screw are rotatably connected to the shaft seats.

[0014] Furthermore, a copper sleeve is provided on the bearing seat so that the screw is rotatably connected to the copper sleeve.

[0015] Furthermore, a handwheel is fixedly connected to the end of the screw. Rotating the handwheel causes the first force-bearing seat to move closer to or further away from the second force-bearing seat.

[0016] Furthermore, the handwheel is fixedly connected to the end of the screw away from the first connecting seat.

[0017] The auxiliary device for disassembling robotic arm components of this invention has the following advantages:

[0018] By setting a first support seat that slides relative to the second support seat on the table, and setting a push rod on the first support seat for ejection, moving the first support seat causes the sixth axis of the five- or six-axis wrist to be disassembled, which is set on the second support seat, to be ejected by the push rod, thus achieving the best disassembly and assembly effect for the five- or six-axis wrist. This application makes flexible contact between the five- or six-axis wrist and the auxiliary device, which not only enables stable fixation and disassembly of the five- or six-axis wrist, but also allows the auxiliary device to automatically adjust back and forth, solving the problems of difficult disassembly and assembly and difficulty in ensuring clearance fit quality caused by the complexity of the five- or six-axis wrist.

[0022] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0023] Those skilled in the art will understand that although some embodiments herein include certain features included in other embodiments but not others, combinations of features from different embodiments are intended to be within the scope of this invention and form different embodiments. For example, in the claims, any of the claimed embodiments can be used in any combination.

[0024] The following is a reference to the appendix. Figure 1 This invention describes an auxiliary device for disassembling robotic arm components.

[0025] like Figure 1 As shown, the auxiliary device for disassembling the robotic arm components in this utility model includes a table frame 1 and a table board 2. The table board 2 is set on the table frame 1. A first connecting seat 3 and a second connecting seat 4 are spaced apart on the table board 2. A screw 5 is rotatably set between the first connecting seat 3 and the second connecting seat 4. The screw 5 drives the first force-bearing seat 6 to slide along the length direction of the table board 2. A second force-bearing seat 7 is set on the table board 2. The five- or six-axis wrist to be disassembled is set on the second force-bearing seat 7. By rotating the screw 5, the push rod 9 set on the first force-bearing seat 6 moves closer to or further away from the five- or six-axis wrist to be disassembled, so that the push rod 9 pushes out the six-axis of the five- or six-axis wrist.

[0026] By setting a first force seat 6 that slides relative to the second force seat 7 on the table 2, and setting a push rod 9 for pushing out on the first force seat 6, the first force seat 6 is moved so that the sixth axis of the five- or six-axis wrist to be disassembled on the second force seat 7 is pushed out by the push rod 9, so that the disassembly and assembly of the five- or six-axis wrist can achieve the best state.

[0027] Furthermore, such as Figure 1 As shown, the first connecting seat 3 and the second connecting seat 4 are fixedly connected to the two ends of the table 2, and the two ends of the screw 5 are rotatably connected to the first connecting seat 3 and the second connecting seat 4, respectively; a slider 10 is screwed onto the screw 5, and a first force-bearing seat 6 is fixedly connected to the slider 10 so that the first force-bearing seat 6 can slide; two slide rails 11 are spaced apart along the length of the table 2 so that the slider 10 can slide on the slide rails 11.

[0028] In this embodiment, preferably, the two ends of the upper surface of the tabletop 2 are vertically connected to the first connecting seat 3 and the second connecting seat 4, respectively. The first connecting seat 3 and the second connecting seat 4 are parallel, so that the two ends of the screw 5 are rotatably connected to the first connecting seat 3 and the second connecting seat 4, respectively, and the arrangement direction of the screw 5 is consistent with the length direction of the tabletop 2.

[0029] Two slide rails 11 are fixedly connected to both sides of the tabletop 2 along the length of the tabletop 2. The two slide rails 11 are parallel to each other, and a slider 10 is screwed onto the screw 5. The two ends of the slider 10 are engaged with the slide rails 11. The first force-bearing seat 3 is fixedly connected to the slider 10. When the screw 5 rotates clockwise, the first force-bearing seat 6 moves along the slide rail 11 toward the second force-bearing seat 7. When the screw 5 rotates counterclockwise, the first force-bearing seat 6 moves along the slide rail 11 away from the second force-bearing seat 7.

[0030] Preferably, the slider 10 has a circular hole at its center that matches the shape of the screw 5. The circular hole has an internal thread structure, and the surface of the screw 5 has an external thread structure, so that the slider 10 and the screw 5 are screwed together.

[0031] Furthermore, such as Figure 1 As shown, the end of the table 2 away from the first force-bearing seat 6 is fixedly connected to the second force-bearing seat 7. Rotating the screw 5 drives the first force-bearing seat 6 to move towards the second force-bearing seat 7, so that the push rod 9 pushes out the six-axis of the five- or six-axis wrist. The second force-bearing seat 7 is provided with a first clamping block 12 and a second clamping block 13, so that the first clamping block 12 and the second clamping block 13 clamp the five- or six-axis wrist to be disassembled.

[0032] In this embodiment, in the initial position, the first force-bearing seat 6 is set on the side near the first connecting seat 3 by the slider 10, and the second force-bearing seat 7 is fixedly connected to the table 2 and located on the side near the second connecting seat 4. The second force-bearing seat 7 is used to fix the five- or six-axis wrist with detachment. By rotating the screw 5, the push rod 9 set on the first force-bearing seat 6 can push out the six-axis of the five- or six-axis wrist, thus completing the disassembly of the five- or six-axis wrist.

[0033] Preferably, the second force-bearing seat 7 is connected to a first clamping block 12 and a second clamping block 13 at a distance from the end of the table 2. The first clamping block 12 and the second clamping block 13 flexibly fix the five- or six-axis wrist to be disassembled on the second force-bearing seat 7. The first clamping block 12 and the second clamping block 13 can also ensure that the five- or six-axis wrist to be disassembled is on the same horizontal line as the push rod 9, so that the push rod 9 can push out the six-axis of the five- or six-axis wrist.

[0034] Furthermore, such as Figure 1As shown, the first connecting seat 3 and the second connecting seat 4 are respectively provided with shaft seats 14 so that both ends of the screw 5 are rotatably connected to the shaft seats 14; the shaft seats 14 are provided with copper sleeves 15 so that the screw 5 is rotatably connected to the copper sleeves 15; a handwheel 16 is fixedly connected to the end of the screw 5, and rotating the handwheel 16 makes the first force-bearing seat 6 move closer to or away from the second force-bearing seat 7; the handwheel 16 is fixedly connected to the end of the screw 5 away from the first connecting seat 3.

[0035] In this embodiment, preferably, a bearing 14 is fixedly connected to the bottom center position of both the first connecting seat 3 and the second connecting seat 4. The bearing 14 is connected to the first connecting seat 3 and the second connecting seat 4 by means of a copper sleeve 15, and ensures that the rotation of the screw 5 will not cause displacement along the length direction of the table board 2.

[0036] A handwheel 16 is welded to the end of the screw 5 away from the first connecting seat 3. When the handwheel 16 is turned clockwise, the first force-bearing seat 6 moves along the slide rail 11 toward the second force-bearing seat 7; when the handwheel 16 is turned counterclockwise, the first force-bearing seat 6 moves along the slide rail 11 away from the second force-bearing seat 7.

[0037] The working principle of the auxiliary device for disassembling robotic arm components in this invention is as follows:

[0038] First, adjust the first clamping block 12 and the second clamping block 13 so that the five- or six-axis wrist to be disassembled is clamped between the first clamping block 12 and the second clamping block 13, and adjust the six-axis of the five- or six-axis wrist to be disassembled to be on the same horizontal line as the push rod 9.

[0039] Then, turn the handwheel 16 clockwise to move the first force seat 6 toward the second force seat 7, and push the push rod 9 to push out the sixth axis that is holding the fifth and sixth axis wrists;

[0040] Finally, turn the handwheel 16 counterclockwise to retract the push rod 9 in the direction of travel, loosen the first clamp 12 and the second clamp 13, and remove the pushed-out six shaft.

[0041] Based on the auxiliary device for disassembling robotic arm components, this utility model achieves flexible contact between the five- or six-axis wrist and the auxiliary device. This not only enables the five- or six-axis wrist to be stably fixed and disassembled, but also allows the auxiliary device to automatically adjust forward and backward. This solves the problems of difficult disassembly and assembly and difficulty in ensuring clearance fit quality caused by the complexity of the five- or six-axis wrist, greatly reducing the consumption of manpower and material resources in the production process and ensuring the stability and quality of workpiece production.

[0042] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
