Description

Technical Field

[0001] The utility model relates to the technical field of gear production tooling and fixtures, and more specifically, to a gear production tooling and fixture. Background Art

[0002] In the existing technology, gear production jigs play an important role in modern manufacturing. They are key equipment to ensure the accuracy and efficiency of gear processing. However, the existing gear production jigs have some significant technical limitations, which seriously affect the performance and operation experience of the jigs.

[0003] First, existing gear production fixtures are not very effective at clamping workpieces. This is usually caused by improper fixture design. Poor clamping means that the workpiece may move unnecessarily during processing, resulting in reduced processing accuracy and even damage to the workpiece or equipment. In addition, poor clamping also increases the adjustment burden on operators and reduces production efficiency.

[0004] The structure of existing gear production fixtures is often complex, which not only increases the manufacturing cost of the equipment, but also makes operation and maintenance difficult. The complex structure may lead to higher equipment failure rate, increased maintenance difficulty and cost, which is a major challenge for the modern manufacturing industry that pursues high efficiency and low cost.

[0005] Most of the existing gear production fixtures cannot adjust their angles, which brings great inconvenience to the workers when they cooperate in gear processing. Since the design and processing requirements of gears vary, the fixed clamping angle may not meet the processing requirements of all workpieces, which limits the applicability and flexibility of the fixture. In addition, fixtures that cannot adjust the angle may also cause the workpiece to be clamped incorrectly, thus affecting the processing quality and efficiency.

[0006] The existing gear production fixtures lack positional limitations, and the workpiece may shift during the clamping process, resulting in inaccuracy in the processing process. This inaccuracy may affect the meshing quality and transmission efficiency of the gears, which is a serious problem for gears with high precision requirements. Utility Model Content
