This utility model relates to the field of diamond grinding and processing technology, and in particular to a fixture for diamond grinding and processing. It solves the problem that in the prior art, due to the uneven surface of diamond tools, traditional fixtures are difficult to use for positioning and clamping, making it difficult to achieve a secure hold, leading to tool wobbling during grinding and affecting processing quality. A fixture for diamond grinding and processing includes a processing table, a support base fixedly mounted on the top of the processing table, a rotating component fixedly mounted on the top of the support base, and a positioning component fixedly mounted on the top of the rotating component. This utility model uses a first cylinder and a second cylinder to drive the fixture assembly with an elastic buffer structure. Utilizing a telescopic rod, a return spring, and rubber chucks, it can adapt to the uneven surface of the diamond grinding tool, achieving a tight fit at multiple contact points, thus solving the problem of unstable fixation caused by poor surface adaptability in traditional fixtures.
