Problems solved by technology
When the positioning element used for detecting the size of parts is used for a long time, it will wear out. Due to the small tolerance of the positioning element, when the positioning element does not meet the requirements, interference or rotation will occur after the parts are installed in the positioning element, which will affect zero. Measurement of component dimensions
[0003] The positioning element is generally Cr12, heat treated to HRC55-60, its material is hard and not easy to wear, the normal operation after wear is to replace the positioning element, but due to the high precision requirements of the positioning element, the production cost of Cr12 material is high, and the cost of remanufacturing the positioning element and debugging The cost is high, and subsequent debugging and testing are required in many aspects, so the cost and delay are relatively high

The invention provides a locally replaceable positioning element. The locally replaceable positioning element comprises a clamp bottom plate, a first positioning part and a second positioning part, the first positioning part and the second positioning part are both arranged on the clamp bottom plate, and the first positioning part is located on the front side of the second positioning part. The first positioning part comprises a positioning block, a positioning gasket and a positioning seat, the positioning seat is detachably arranged on the clamp bottom plate, the positioning gasket is arranged on the positioning seat, the positioning block is arranged on the positioning gasket, the positioning block is connected with the positioning seat, and the positioning gasket is clamped and fixed between the positioning block and the positioning seat. The second positioning part comprises a positioning core and a positioning vertical plate, the positioning vertical plate is arranged on the clamp bottom plate, and the positioning core is detachably arranged on the top of the side surface of the positioning vertical plate. High-cost element replacement is replaced by local low-cost gasket replacement, so that the cost is reduced, debugging is facilitated, the detection efficiency is improved, and the service life of the positioning block is prolonged.
Description
technical field [0001] The invention relates to a positioning element, in particular to a partially replaceable positioning element. Background technique [0002] The processing and manufacturing industry has very strict requirements on parts and fixtures, and has very high requirements on repeated positioning. The positioning element used for detecting the size of parts will wear out after long-term use. Due to the small tolerance of the positioning element, when the positioning element does not meet the requirements, interference or rotation will occur after the parts are loaded into the positioning element, which will affect zero. Measurement of component dimensions. [0003] The positioning element is generally Cr12, heat treated to HRC55-60, its material is hard and not easy to wear, the normal operation after wear is to replace the positioning element, but due to the high precision requirements of the positioning element, the production cost of Cr12 material is high, ...
