Description

Technical Field

[0001] This utility model belongs to the field of automotive parts processing technology, specifically relating to a clamping fixture for processing automotive anti-collision beams. Background Technology

[0002] In the automotive manufacturing industry, the car crash beam is a key component for ensuring vehicle safety. Its processing accuracy and quality directly affect the safety performance of the car in a collision accident. Therefore, in the processing of car crash beams, stable clamping and precise positioning of the workpiece are the core links to ensure processing quality. At present, in the actual processing operation of car crash beams, the traditional clamping and fixing methods mostly rely on manual clamping with clamps. This traditional method can still meet the basic processing requirements when dealing with some relatively short and simple workpieces. The operation is relatively simple and the cost is also relatively low.

[0003] However, with the continuous development of the automotive industry, the design of automotive anti-collision beams has become increasingly complex, and their dimensions have become longer. When using clamps to fix these long automotive anti-collision beam workpieces, multiple fixing points need to be set on the workpiece to ensure its stability throughout the entire processing. This not only greatly increases the workload and difficulty of operation for operators, making the entire fixing process cumbersome and time-consuming, and reducing production efficiency, but also makes it difficult to ensure that the clamping force of each fixing point is completely consistent during operation due to the multiple fixing points. This creates hidden dangers for subsequent processing. In addition, there is a significant problem with the clamp fixing method: after long-term use, or affected by factors such as vibration and impact during processing, the clamps are prone to loosening. Once the clamps loosen, the workpiece cannot be kept stably fixed and is prone to displacement during processing. This displacement will cause the processing dimensions to deviate, making the processed automotive anti-collision beams not meet the design requirements, thereby seriously reducing the product qualification rate, wasting raw materials, and increasing production costs. Therefore, this utility model proposes a clamping fixture for processing automotive anti-collision beams. Utility Model Content

[0036] Example 2

[0037] Please see Figures 1 to 6 This is the second embodiment of the present invention. This embodiment is based on the previous embodiment, but the difference is that the top surface of the Z-axis clamping block 213 is connected to a top seat plate 214, and a bolt hole 215 is connected between the top seat plate 214 and the Z-axis swing clamping arm 212.

When the Z-axis clamping block 213 is damaged and needs to be replaced, there is no need to disassemble the top plate 214 and the Z-axis swing clamping arm 212. Simply pull the Z-axis clamping block 213 down forcefully, so that the L-shaped rubber seat 2131 and the triangular clamping block 2132 are squeezed and elastically deformed. Finally, the triangular clamping block 2132 is squeezed out from the side slot 2142, and the L-shaped rubber seat 2131 can be easily pulled out from the rectangular socket 2141. This allows for quick and individual disassembly and replacement of the Z-axis clamping block 213, improving the convenience of subsequent maintenance of the entire tooling.
