Abstract
Description
Technical Field
[0001] This utility model relates to the field of machinery, and more particularly to tooling fixtures, especially a welding fixture for automotive frame steel wire parts. Background Technology
[0002] The steel wire skeleton parts used in automobiles are welded together from multiple steel wires. Some more complex-shaped automotive steel wire skeleton parts are also composed of a large number of steel wires. It is necessary to first position and fix these multiple steel wires before welding. However, existing tooling cannot effectively fix these steel wires, resulting in poor welding quality and low welding efficiency. Furthermore, existing technologies use manual clamps to fix the steel wires, requiring a large number of clamps and manual clamping of each one, which is inefficient. Utility Model Content

The base plate is provided with eight first clamping mechanisms arranged from left to right at intervals. In front of the first clamping mechanisms, the base plate is provided with three second clamping mechanisms arranged from left to right at intervals. In front of the second clamping mechanisms, the base plate is provided with seven third clamping mechanisms arranged from left to right at intervals. In front of the third clamping mechanisms, the base plate is provided with eleven fourth clamping mechanisms arranged from left to right at intervals. In front of the fourth clamping mechanisms, the base plate is provided with six fifth clamping mechanisms arranged from left to right at intervals. In front of the fifth clamping mechanisms, the base plate is provided with eight sixth clamping mechanisms arranged from left to right at intervals.
[0005] Each of the first, second, third, fourth, fifth, and sixth clamping mechanisms includes a cylinder, a first connecting rod, a second connecting rod, a support, at least one pressure block, and at least one fixed seat. The cylinder is fixedly mounted on the base plate, and the support is fixedly mounted on the base plate or the cylinder. The control end of each cylinder is connected to a pneumatic control system. The piston rod of the cylinder is hinged to one end of the first connecting rod, one end of the second connecting rod is hinged to the support, and the other end of the second connecting rod is hinged to the middle of the first connecting rod. The other end of the first connecting rod is connected to the pressure block. The fixed seat is fixedly mounted on the base plate below the pressure block, and each fixed seat has a wire fixing groove on its upper surface.
[0006] Furthermore, the cylinders in the fifth clamping mechanism are all mounted on the lower surface of the base plate.
[0007] Compared with existing technologies, the advantages of this invention are positive and significant. This invention provides a welding fixture for automotive frame steel wire parts, which has a simple structure and is easy to operate. It utilizes a pneumatic control system to control a cylinder, which drives a pressure block to quickly and accurately position and fix the steel wire parts, eliminating the need for manual clamping and improving the welding quality and efficiency of automotive frame steel wire parts.

[0013] like Figures 1-4 As shown, this utility model provides a welding fixture for automotive frame steel wire parts, including a base plate. The base plate is provided with eight first clamping mechanisms 1 arranged from left to right at intervals. In front of the first clamping mechanisms 1, the base plate is provided with three second clamping mechanisms 2 arranged from left to right at intervals. In front of the second clamping mechanisms 2, the base plate is provided with seven third clamping mechanisms 3 arranged from left to right at intervals. In front of the third clamping mechanisms 3, the base plate is provided with eleven fourth clamping mechanisms 4 arranged from left to right at intervals. In front of the fourth clamping mechanisms 4, the base plate is provided with six fifth clamping mechanisms 5 arranged from left to right at intervals. In front of the fifth clamping mechanisms 5, the base plate is provided with eight sixth clamping mechanisms 6 arranged from left to right at intervals.
[0014] Each of the first clamping mechanism 1, the second clamping mechanism 2, the third clamping mechanism 3, the fourth clamping mechanism 4, the fifth clamping mechanism 5, and the sixth clamping mechanism 6 includes a cylinder 7, a first connecting rod 8, a second connecting rod 9, a support 10, at least one pressure block 11, and at least one fixed seat 12. The cylinder 7 is fixedly mounted on the base plate, and the support 10 is fixedly mounted on the base plate or the cylinder 7. The control end of each cylinder 7 is connected to a pneumatic control system. The piston rod of the cylinder 7 is hinged to one end of the first connecting rod 8, one end of the second connecting rod 9 is hinged to the support 10, and the other end of the second connecting rod 9 is hinged to the middle of the first connecting rod 8. The other end of the first connecting rod 8 is connected to the pressure block 11.

[0017] The working principle of this utility model:
[0018] Figure 3 The image shows a steel wire frame component for an automobile. Figure 4 The disassembled structure of steel wire parts for automotive skeletons, such as Figure 1 As shown, place each part of the automotive frame wire component into the wire fixing groove on the corresponding fixing seat 12, and then, as... Figure 2 As shown, the piston rods of each cylinder 7 are extended by the pneumatic control system. The piston rods of the cylinder 7 drive the first connecting rod 8 to press down, and the first connecting rod 8 drives the pressure block 11 to press down. The pressure block 11 presses on the wire parts, fixing the wire parts in the wire fixing groove of the fixing seat 12. Then, the welding operation can be performed on each wire part. After the welding is completed, the piston rods of each cylinder 7 are retracted by the pneumatic control system, which drives the pressure block 11 to lift up, so that the steel wire parts of the car frame can be removed.
[0019] This utility model discloses a welding fixture for automotive frame steel wire parts. It has a simple structure and is easy to operate. It uses a pneumatic control system to control the cylinder 7, which drives the pressure block 11 to quickly and accurately position and fix the steel wire parts. No manual clamping is required, which improves the welding quality and welding efficiency of automotive frame steel wire parts.
