The toothed positioning fixture is a fixture designed for precise positioning and fixing. It is widely used in CNC machining centers, inspection and measurement, assembly processes, welding processes and other scenarios. Its toothed structure provides multi-angle and multi-directional positioning functions, has high stability and repeatable positioning accuracy, and can remain firm even in high-vibration environments. The fixture is usually made of high-strength steel or stainless steel. Some products are suitable for corrosion-resistant or high-temperature environments, and are designed with quick adjustment mechanisms to improve operational convenience. The highly adaptable toothed positioning fixture can be used in conjunction with various types of processing equipment to provide reliable support for workpiece processing and fixing. It is an efficient and flexible industrial auxiliary tool.
