[0023] See also Figure 1-4 , the utility model provides a technical solution:

[0024] The chassis welding positioning bracket for vehicle processing includes two groups of support frames 1, two groups of shells 13 and lifting components for vertically lifting the two groups of shells 13 are integrated between the two groups of support frames 1. The inner surface walls of the two groups of shells 13 are fixedly connected to the rotating parts 14, the output ends of the rotating parts 14 are fixedly connected to the rotating rods 15, the open ends of the rotating rods 15 are fixedly connected to the flip frame 2 through the protrusions 16, the inner surface walls of the flip frame 2 are provided with two groups of movable seats 3, and the bottoms of the two groups of movable seats 3 are provided with clamping components. The outer surface wall of the shell 13 is fixedly connected to the support sleeve 12, and the inner surface wall of the support sleeve 12 is rotatably connected to the protrusion 16 through the bearing 17;

[0025] After the chassis is clamped by the clamping assembly at the bottom of the mobile seat 3, the flip frame 2 and the chassis are raised to a specified height through the lifting assembly, and the protruding rod 5 slides along the vertical slot 7. Subsequently, the rotating rod 15 can be driven to rotate by the rotating member 14 inside the shell 13, and the rotating rod 15 is linked to the flip frame 2 through the protruding seat 16 to realize the flipping of the base in the fixed state. The support sleeve 12 is fixed to the shell 13, and the support sleeve 12 is sleeved on the outside of the protruding seat 16, and the rotation cooperation of the support sleeve 12 and the protruding seat 16 is realized by the bearing 17, thereby avoiding the gravity from acting completely on the rotating rod 15, improving the fatigue resistance of the rotating rod 15, and at the same time, the locking sleeve 6 can be rotated to make it screwed with the protruding rod 5 until the locking sleeve 6 is tightly fitted with the outer wall of the support frame 1, and the friction force generated thereby can be used for auxiliary support of the support sleeve 12, thereby further ensuring the position stability of the support sleeve 12.

[0026] Specifically, such as Figure 2 and Figure 4 As shown, the bottom of the flip frame 2 is fixedly connected to a driving member 4, and the output end of the driving member 4 is fixedly connected to a transmission rod 8. The outer wall of the transmission rod 8 is screwed with two groups of screw sleeves 11 through two groups of opposite thread grooves. The two groups of screw sleeves 11 are respectively fixedly connected to the bottom of the two groups of moving seats 3. The bottom of the flip frame 2 is fixedly connected to a polished rod 9. The bottoms of the two groups of moving seats 3 are fixedly connected with a sliding sleeve 10 that slides with the polished rod 9. The driving member 4 drives the transmission rod 8 to rotate, and the transmission rod 8 is screwed with the two groups of screw sleeves 11 through two groups of opposite thread grooves on the outer wall. The two groups of screw sleeves 11 link the two groups of moving seats 3 to move relative to each other. The sliding cooperation of the two groups of sliding sleeves 10 and the polished rod 9 ensures the stability of the movement of the two groups of moving seats 3, so that the two groups of clamping components can be adjusted in spacing to adapt to chassis of different sizes, thereby improving the scope of application of the chassis welding positioning bracket for vehicle processing.

[0027] Specifically, such as Figure 2 and Figure 3 As shown, the outer wall of the middle part of the support sleeve 12 is fixedly connected with a protruding rod 5, and the outer wall of the protruding rod 5 is provided with a fixing portion for fixing the protruding rod 5 to the support frame 1. The protruding rod 5 includes a threaded section and a smooth section. The outer wall of the smooth section is slidably connected to the inner wall of the support frame 1 through a vertical groove 7, so as not to affect the vertical movement of the support sleeve 12. The fixing portion includes a locking sleeve 6 screwed together with the threaded section, and the outer wall of the locking sleeve 6 abuts against the outer wall of the support frame 1. The locking sleeve 6 is rotated to screw it into the protruding rod 5 until the locking sleeve 6 is tightly fitted with the outer wall of the support frame 1. The friction force generated thereby can provide auxiliary support for the support sleeve 12.

[0028] Working principle: After the chassis is clamped by the clamping assembly at the bottom of the mobile seat 3, the flip frame 2 and the chassis are raised to a specified height through the lifting assembly, and the protruding rod 5 slides along the vertical slot 7. Subsequently, the rotating rod 15 can be driven to rotate by the rotating member 14 inside the shell 13. The rotating rod 15 is linked to the protruding seat 16 to realize the flipping of the base in a fixed state. The support sleeve 12 is fixed to the shell 13, and the support sleeve 12 is sleeved on the outside of the protruding seat 16. The support sleeve 12 and the protruding seat 16 are rotated together by the bearing 17 to avoid the gravity from acting completely on the rotating rod 15, thereby improving the fatigue resistance of the rotating rod 15 and being rotatable and locked. The sleeve 6 is screwed together with the convex rod 5 until the locking sleeve 6 is tightly fitted with the outer wall of the support frame 1. The friction force generated by this can provide auxiliary support for the support sleeve 12, which can further ensure the stable position of the support sleeve 12. The driving member 4 drives the transmission rod 8 to rotate, and the transmission rod 8 is screwed together with the two groups of screw sleeves 11 through two groups of opposite thread grooves on the outer wall. The two groups of screw sleeves 11 link the two groups of moving seats 3 to move relative to each other. The sliding cooperation of the two groups of sliding sleeves 10 and the light rod 9 ensures the stable movement of the two groups of moving seats 3, thereby realizing that the spacing between the two groups of clamping components can be adjusted to adapt to chassis of different sizes, thereby improving the scope of application of chassis welding positioning brackets for vehicle processing.
