Detailed Implementation

[0010] The following description, in conjunction with the accompanying drawings, details a welding fixture for a stabilizer bracket according to this utility model.

[0011] This utility model relates to a welding fixture for a stabilizer bracket. (See also...) Figures 1 to 6 , It includes a support frame 1, a stabilizer bracket positioning mechanism 2, a stabilizer bracket fixing mechanism 3, and a shock absorber body fixing mechanism 4; the stabilizer bracket positioning mechanism 2, the stabilizer bracket fixing mechanism 3, and the shock absorber body fixing mechanism 4 are all assembled on the support frame 1, and the support frame 1 serves as the installation base to achieve the coordinated operation of each mechanism.

[0012] The stabilizer bracket positioning mechanism 2 includes a support positioning seat 21, a cylinder support frame 22, a cylinder port support seat 23, a retaining ring 24, a first gasket 25, a first cylinder 26, and a second cylinder 27. The support positioning seat 21 is fixed to the support frame 1 and is used to define the placement direction of the workpiece and the lateral positioning reference. The cylinder support frame 22 and the cylinder port support seat 23 are fixedly connected to the support frame 1. The retaining ring 24 is installed on the side of the cylinder port support seat 23 near the workpiece. The connecting surfaces of the cylinder support frame 22, the cylinder port support seat 23, and the retaining ring 24 are all provided with a first gasket 25. By increasing or decreasing the number of first gaskets 25 or replacing them with gaskets of different thicknesses, the height and front-back position of the cylinder support frame 22, the cylinder port support seat 23, and the retaining ring 24 can be precisely adjusted to ensure the placement accuracy of the cylinder. Cylinder 1 26 and Cylinder 2 27 are fixed to the support frame 1 by bolts. The piston rod of Cylinder 1 26 is aligned with the retaining ring 24. After starting, the cylinder can be locked onto the retaining ring 24 to ensure that the cylinder positioning position is consistent each time. After welding is completed, Cylinder 1 26 retracts and the piston rod of Cylinder 2 27 extends to push the workpiece away from the positioning position, making it convenient for manual material removal.

[0013] The stabilizer bracket fixing mechanism 3 includes a stabilized rear bracket positioning block 31, a positioning pin 32, a front-to-back angle adjustment block 33, a left-to-right angle adjustment block 34, a second shim, a height limiting block 35, a third cylinder 36, and a fourth cylinder 37. The stabilized rear bracket positioning block 31 is connected to the support frame 1 via the positioning pin 32. The positioning pin 32 restricts the initial displacement of the stabilized rear bracket positioning block 31, ensuring the stability of the positioning reference. The front-to-back angle adjustment block 33 and the left-to-right angle adjustment block 34 are respectively fixed to the support frame 1 by bolts and are located at the front and back, and left and right sides of the stabilized rear bracket positioning block 31, respectively. The mating surfaces of the stabilized rear bracket positioning block 31 and the front-to-back angle adjustment blocks 33 and left-to-right angle adjustment blocks 34 are all provided with second shims. By adjusting the thickness of the second shims and the installation positions of the front-to-back angle adjustment blocks 33 and left-to-right angle adjustment blocks 34, the angle and position of the stabilized rear bracket positioning block 31 can be finely adjusted to ensure that the stabilizer bracket can be accurately pushed to the designated welding position of the cylinder. The height limiting block 35 is fixed to the support frame 1 to limit the rising height of the stabilizing bracket positioning block 31. Cylinder 36 and cylinder 4 37 are fixed to the support frame 1. The piston rod of cylinder 36 is connected to the stabilizing bracket positioning block 31. After starting, it drives the stabilizing bracket positioning block 31 to move upward and abut against the height limiting block 35 to ensure that the welding height of the stabilizer bracket is consistent. Then, the piston rod of cylinder 4 37 retracts and presses the stabilizer bracket against the cylinder barrel through the stabilizing bracket positioning block 31, thereby achieving relative fixation between the stabilizer bracket and the cylinder barrel.

[0014] The shock absorber body fixing mechanism 4 includes a positioning component 41 and a tilting and pressing cylinder 42. The positioning component 41 is fixed to the support frame 1 and is used to position the shock absorber body in the left and right directions to prevent lateral displacement. The cylinder body of the tilting and pressing cylinder 42 is connected to the support frame 1 through a hinge seat 44, and a pressing element 43 is installed at the end of its piston rod. After the positioning component 41 completes the left and right positioning, the tilting and pressing cylinder 42 is activated, and the piston rod drives the pressing element 43 to tilt and press against the shock absorber body, fixing the shock absorber body in the designated position and preventing shaking during welding.

[0015] The working process of this utility model tooling is as follows: The stabilizer bracket is manually placed on the stabilizing support positioning block 31, and the cylinder is placed on the cylinder support frame 22 and the cylinder port support seat 23. The placement direction and lateral position are determined by the support positioning seat 21. After pressing the start button, cylinder 26 of the stabilizer bracket positioning mechanism 2 extends, locking the cylinder against the retaining ring 24 for positioning. The positioning component 41 of the shock absorber body fixing mechanism 4 first positions the workpiece left and right, then the flipping and clamping cylinder 42 actuates, driving the clamping component 43 to flip and clamp the workpiece. Cylinder 36 of the stabilizer bracket fixing mechanism 3 extends, driving the stabilizing support positioning block 31 to abut against the height limiting block 35. Then, cylinder 37 retracts, clamping the stabilizer bracket to the designated position of the cylinder. Afterwards, a welding robot welds the connection between the stabilizer bracket and the cylinder. After welding is completed, cylinders 36 and 37 of the stabilizer bracket fixing mechanism 3 retract in sequence, the flipping and pressing cylinder 42 of the shock absorber body fixing mechanism 4 retracts and flips, cylinder 26 of the stabilizer bracket positioning mechanism 2 retracts and cylinder 27 extends to push the workpiece out, and finally the workpiece is removed manually to complete one welding operation.
