Technical Field
[0001] This utility model relates to the field of automotive parts processing technology, and in particular to an adjustable fixing structure for processing a lower thrust rod bracket. Background Technology
[0002] In the automotive parts manufacturing industry, the lower thrust rod bracket is a key component of the suspension system, and its machining accuracy directly affects the vehicle's stability and safety. Traditional fixing structures mostly use rigid clamping methods, which have the following significant drawbacks:
[0003] Poor adaptability: Existing fixing devices are mostly designed with a single size, which cannot be flexibly adjusted to adapt to different models of lower thrust rod brackets, resulting in frequent clamp replacements when changing models, which is time-consuming and labor-intensive.
[0004] Low positioning accuracy: The bracket is prone to displacement due to vibration or uneven force during the welding process. Traditional guide structures lack dynamic compensation function, resulting in welding position deviation and low finished product qualification rate.
[0005] To address the aforementioned issues, there is an urgent need for an adjustable fixing structure that can achieve rapid adaptation and high-precision positioning, thereby improving production efficiency and product consistency. Utility Model Content

A lower thrust rod fixing assembly is provided at one end of the top outer wall of the base, and a lower thrust rod placement component is provided on the outer wall of the lower thrust rod fixing assembly. A rotary welding assembly is provided at the other end of the top outer wall of the base, and a clamping assembly is provided between the lower thrust rod fixing assembly and the rotary welding assembly on the top outer wall of the base.

[0010] Preferably, the lower thrust rod placement component includes a lower thrust rod placement seat and a guide plate, wherein the lower thrust rod placement seat is welded to the top outer wall of the first machine base, and the guide plate is disposed on the inclined surface of the lower thrust rod placement seat.
[0011] Preferably, the clamping assembly includes a second machine base welded to the top outer wall of the base, second hydraulic push rods disposed on both sides of the top of the second machine base, and a clamp mounted on the piston rod of the second hydraulic push rod.
[0012] Preferably, the rotary welding assembly includes a slide rail welded to the top outer wall of the base, an electric guide rail fixed to the bottom inner wall of the slide rail by bolts, a housing mounted on the electric guide rail slider, and a chuck disposed on one side outer wall of the housing.
[0013] Preferably, the top outer wall of the lower thrust rod placement seat is provided with a slot, and the inner wall of the slot is provided with a lower thrust rod bracket.
[0014] Preferably, the inner walls on both sides of the second machine tool are provided with sliding grooves, and the clamps are slidably connected to the inner walls of the sliding grooves.

[0016] The beneficial effects of this utility model are as follows:
[0017] 1. The adjustable fixing structure is used for the processing of the lower thrust rod bracket in this design. The lower thrust rod fixing component adopts the first hydraulic push rod to drive the lower pressure arm. Combined with the triangular frame hinge structure, the height and tilt angle of the lower pressure plate can be infinitely adjusted to adapt to the curved surface of the bracket with different curvatures, ensuring uniform distribution of clamping force. The inclined surface design of the guide plate can guide the bracket to slide into the slot automatically, realize the self-centering function, and reduce manual adjustment time.
[0018] 2. The adjustable fixing structure used in the lower thrust rod bracket of this design is used for processing. When the chuck slides along the slide groove, it is constrained on both sides to avoid lateral displacement. With the synchronous extension and retraction of the second hydraulic push rod, the workpiece is symmetrically clamped on both sides to prevent welding deformation. After the workpiece is fixed by the clamping assembly, the rotating welding assembly can automatically move to the preset position along the slide rail to realize continuous clamping-welding operation and reduce process changeover time.
