The lathe turnover fixture has simple structure, convenient operation, capability of processing both surfaces of workpieces and high processing efficiency.

Description

technical field [0001] The invention relates to a fixture, in particular to a turning fixture for a lathe. Background technique [0002] Lathe processing products are usually processed on one side and clamped again to process the other side, or products with a certain angle are positioned and clamped by tooling according to the angle, and the angle turning is realized through the fixture, and the processing is carried out in sequence, usually in multiple installments Clamp processing to complete a part, often in mass production, a product needs to be realized on several lathes, that is, each lathe processes a process, so due to the size of the processing surface, the degree of difficulty is different, and the processing time of each process is different. In the case where the process is not easy to achieve balance, either use re-products for balance, or sacrifice equipment utilization. For small batch products, one side is usually processed first, and then the other side is ...

[0002] Lathe processing products are usually processed on one side and clamped again to process the other side, or products with a certain angle are positioned and clamped by tooling according to the angle, and the angle turning is realized through the fixture, and the processing is carried out in sequence, usually in multiple installments Clamp processing to complete a part, often in mass production, a product needs to be realized on several lathes, that is, each lathe processes a process, so due to the size of the processing surface, the degree of difficulty is different, and the processing time of each process is different. In the case where the process is not easy to achieve balance, either use re-products for balance, or sacrifice equipment utilization. For small batch products, one side is usually processed first, and then the other side is processed. The processing efficiency is relatively low, and each side must be clamped once. Moreover, the principle that the rough datum can only be used once, so the workpiece after the second clamping is the fine datum after processing, which is prone to pinch defects. For the current competitive environment of multi-variety and small-batch production, many companies are increasingly Focusing on the concentration of processes, the application of functional fixtures is becoming more and more urgent. In response to the above situation, the company has invested manpower and material resources in the research and development of turning fixtures for lathes.
