[0027] Specifically, the outer surface of the electric slide rail 3 slides with the inner wall of the electric slider 5 and is electrically connected to the electric slider 5 through a wire;

[0028] In this embodiment, the sliding cooperation between the electric slide rail 3 and the electric slider 5 can move the support base 6 so that the support base 6 is close to the clamping frame 2.

[0029] Specifically, the drive motor 601 is a reciprocating motor. The output end of the drive motor 601 passes through the rear surface of the support base 6 and is fixed to the rear end of the transmission screw 603. The outer surface of the transmission screw 603 is threadedly connected to the inner wall of the movable support block 605. The outer surface of the slide rod 604 is slidably connected to the inner wall of the movable support block 605.

[0030] In this embodiment, the inner wall of the bottom end of the mounting groove 602 is flush with the bottom surface of the support seat 6. The drive motor 601 is mainly used to drive the transmission screw 603, and the transmission screw 603 is mainly used to perform screw transmission with the movable support block 605. The sliding rod 604 is set to make it slide with the movable support block 605, thereby realizing the displacement limitation of the movable support block 605, thereby achieving the effect of smooth movement of the movable support block 605, and meeting the movement requirements of the subsequent welding base 607.

[0031] Specifically, the output end of the rotary motor 608 passes through the right side surface of the welding base 607 and is fixedly connected to the right end of the rotary head 609;

[0032] In this embodiment, the hydraulic rod 606 is mainly used to adjust the height of the welding base 607, and the rotating head 609 is used to fix and clamp the welding workpiece. Driven by the rotating motor 608, the welding workpiece is rotated, meeting the welding requirements between the welding workpiece and the frame.

[0033] In this embodiment, please refer to Figure 1 and Figure 3 The clamping and positioning mechanism 4 includes positioning slots 401 respectively provided on the right side surface of the clamping frame 2, and an electric push rod 402 and a sliding support block 403 are respectively provided inside the positioning slots 401. A positioning support block 404 is fixedly installed on the right side of the sliding support block 403, and a positioning rod 405 is provided on the outer side of the positioning support block 404. A spring 406 is sleeved on the outer side of the positioning rod 405, and a clamping block 407 is installed on the inner side of the positioning support block 404;

[0034] Specifically, the positioning slide 401 is distributed in a front-to-back mirror image with respect to the right side surface of the clamping frame 2, and its inner wall is in contact with the outer surface of the sliding support block 403, the telescopic end of the electric push rod 402 is welded to one side of the sliding support block 403, and the end of the positioning rod 405 away from the positioning support block 404 is fixedly installed with an anti-slip block, and the other end of the positioning rod 405 is fixed to the outer surface of the anti-slip block, and the other end is fixed to the outer surface of the positioning support block 404, and the inner surface of the clamping block 407 is provided with a rubber pad;

[0035] In this embodiment, the electric push rod 402 is mainly used to move the sliding support block 403. When the sliding support block 403 and the positioning slide groove 401 slide in contact, the positioning support block 404 drives the clamping block 407 to move toward each other, and the positioning rod 405 is mainly used to form a contact movement with the inner wall of the positioning support block 404, thereby achieving stable support for the clamping block 407. The spring 406 is set to absorb the local stress applied by the clamping block 407 to the outside of the frame, thereby avoiding the clamping block 407 applying excessive rigid contact force to the frame during the clamping process, facilitating the protection of the frame, and meeting the clamping and positioning requirements of the frame.

[0036] The working process of the present invention is as follows: in a friction welding positioning device for a vehicle frame, the device is first moved to the desired position, and then the vehicle frame is moved so that the vehicle frame gradually approaches and contacts the clamping frame 2, and then the vehicle frame is positioned and clamped, and the electric push rod 402 is started, and the telescopic end of the electric push rod 402 gradually extends and drives the sliding support block 403 to slide along the inner wall of the positioning slide groove 401, and the positioning support block 404 and the clamping block 407 gradually approach the outer surface of the vehicle frame as the sliding support block 403 moves. When the clamping block 407 contacts the outer surface of the vehicle frame, the positioning rod 405 slides along the inner wall of the positioning support block 404 and stretches the spring 406 through the anti-slip block, and the spring 406 can absorb the rigid contact force generated between the clamping block 407 and the vehicle frame during the stretching process, thereby effectively It prevents the frame from being deformed due to excessive rigid contact force, which is convenient for subsequent use. Finally, the welding workpiece can be contacted and fixed with the rotating head 609. Under the sliding of the electric slide rail 3 and the electric slider 5, the support seat 6 can be moved left and right, and the driving motor 601 can drive the transmission screw 603 to rotate, so that the moving support block 605 slides along the outer surface of the slide bar 604, thereby realizing the forward and backward movement of the welding base 607. Under the telescopic action of the hydraulic rod 606, the vertical movement of the welding base 607 is realized, which facilitates the contact between the welding work and the welding part of the frame. At the same time, under the drive of the rotating motor 608, the rotating head 609 drives the welding workpiece to rotate, thereby achieving the effect of friction welding between the frame and the welding workpiece, meeting the needs of users.
