The purpose of the accompanying drawings is to supplement the description of the text part of the specification with graphics, so that people can intuitively and vividly understand each technical feature and overall technical solution of the present invention, but it cannot be understood as a limitation on the scope of protection of the present invention.

[0020] See also Figure 1-4 The utility model provides a technical solution: a control arm processing positioning and clamping tool, including a chassis 1, a cross guide frame 3 is fixedly installed on the inner wall of the chassis 1, a movable box 4 is slidably installed on the outer wall of the cross guide frame 3, an L-shaped rod 5 is rotatably installed on the top and bottom of the movable box 4, and a pressure cylinder 6 is slidably installed on the outer wall of the L-shaped rod 5. A mechanical arm 2 is arranged between the chassis 1 and the pressure cylinder 6, and also includes a fixing component installed on the movable box 4, which is used to fix the L-shaped rod 5 through the fixing component, and a threaded rod 10 installed on the top of the chassis 1 is rotatably installed, and the movable box 4 is threadedly installed on the outer wall of the threaded rod 10. The threaded rod 10 is manually twisted, and the threaded rod 10 drives the movable box 4, the L-shaped rod 5, and the pressure cylinder 6 to move downward, so that the pressure cylinder 6 clamps the mechanical arm 2 on the top of the chassis 1, and a steering structure installed on one side of the chassis 1 is used to flip the chassis 1 and the mechanical arm 2 through the steering structure.

[0021] A movable hole is provided on the top of the chassis 1 , and the L-shaped rod 5 is movably installed in the movable hole.

[0022] The fixing assembly includes a fixing bolt B8 and a push block 9. The fixing bolt B8 is threadedly installed on the top of the chassis 1. The push block 9 is slidably installed on the inner wall of the movable box 4, and the push block 9 contacts the outer wall of the L-shaped rod 5.

[0023] One side of the push block 9 is set at an angle, and a round hole is opened on the top of the movable box 4. One end of the fixing bolt B8 passes through the round hole and contacts one side of the push block 9. When the fixing bolt B8 is manually twisted, the fixing bolt B8 will move downward, so that the bottom end of the fixing bolt B8 pushes the push block 9 to the left, increasing the friction between the push block 9 and the L-shaped rod 5, and preventing the L-shaped rod 5 and the pressure cylinder 6 from rotating.

[0024] The steering structure includes a side seat 11, a rotating shaft 12, a motor 13, a rotating rod 14, a bevel gear A15, and a bevel gear B16. The side seat 11 is located on the other side of the chassis 1. The rotating shaft 12 is rotatably installed on both sides of the side seat 11. The motor 13 is fixedly installed on the top outer wall of the side seat 11. The rotating rod 14 is rotatably installed on the inner top of the side seat 11.

The output shaft of the motor 13 is fixedly installed on one end of the rotating rod 14. When the motor 13 is started, the output shaft of the motor 13 drives the rotating rod 14 and the bevel gear A15 to rotate. The rotation of the bevel gear A15 drives the bevel gear B16, the rotating shaft 12, the chassis 1, and the robotic arm 2 to rotate, thereby changing the positions of the chassis 1 and the robotic arm 2. The robotic arm 2 can be turned to the processing area, and automatic alternation of the robotic arm 2 can be achieved, further improving the processing efficiency of the robotic arm 2.

[0025] A fixing bolt A7 is installed on the top thread of the pressing cylinder 6. One end of the fixing bolt A7 contacts the outer wall of the L-shaped rod 5. When the fixing bolt A7 is manually twisted, one end of the fixing bolt A7 squeezes the L-shaped rod 5, increasing the friction between the fixing bolt A7 and the L-shaped rod 5 to prevent the pressing cylinder 6 from moving left and right.

[0026] There are two cross guide frames 3 and they are symmetrically arranged on the left and right. Each cross guide frame 3 is provided with four movable boxes 4, L-shaped rods 5, pressure cylinders 6, fixing bolts A7, fixing bolts B8, push blocks 9, and threaded rods 10. The four movable boxes 4, L-shaped rods 5, pressure cylinders 6, fixing bolts A7, fixing bolts B8, push blocks 9, and threaded rods 10 are arranged in a circular array, which can perform multiple clamping of the robotic arms 2. In the process of processing one of the robotic arms 2, the robotic arms 2 on the other sides can be clamped or disassembled, which greatly reduces the workpiece loading and unloading time and improves the processing efficiency of the robotic arms 2.

[0027] Working principle: Place the robot arm 2 on the top of the chassis 1, then manually twist the pressure cylinder 6 and the L-shaped rod 5 to drive the pressure cylinder 6 to the top of the robot arm 2, then manually twist the fixing bolt B8, the fixing bolt B8 will move downward, so that the bottom end of the fixing bolt B8 pushes the push block 9 to the left, increasing the friction between the push block 9 and the L-shaped rod 5 to prevent the L-shaped rod 5 and the pressure cylinder 6 from rotating, then manually twist the fixing bolt A7, one end of the fixing bolt A7 squeezes the L-shaped rod 5, increasing the friction between the fixing bolt A7 and the L-shaped rod 5 to prevent the pressure cylinder 6 from moving left and right, then Manually twist the threaded rod 10, and the threaded rod 10 drives the movable box 4, the L-shaped rod 5, and the pressing cylinder 6 to move downward, so that the pressing cylinder 6 clamps the robot arm 2 on the top of the chassis 1, and by starting the motor 13, the output shaft of the motor 13 drives the rotating rod 14 and the bevel gear A15 to rotate. The rotation of the bevel gear A15 drives the bevel gear B16, the rotating shaft 12, the chassis 1, and the robot arm 2 to rotate, turning the robot arm 2 to the processing area, and turning the processed robot arm 2 back from the processing area, so that when one robot arm 2 is being processed, the other two robot arms 2 can be clamped and disassembled.
