Description
技术领域technical field
本实用新型涉及一种夹具，特别涉及一种汽车发动机气缸体曲轴孔加工翻转夹具。The utility model relates to a jig, in particular to a turning jig for machining crankshaft holes in cylinder blocks of automobile engines.
背景技术Background technique
目前，汽车发动机的气缸体曲轴孔加工精度要求高，难度大，公知的气缸体曲轴孔加工采用卧式镗床加工，加工精度难以达到要求。实践证明只有采用立式珩磨机加工才能保证曲轴孔的加工精度，气缸体曲轴孔加工时，其上料、加工和下料过程均是自动输送完成的，为了保证上、下料过程中气缸体运行平稳，采用底面为输送面，因而气缸体须翻转90度，才能使加工孔与磨头在同一方向。At present, the machining accuracy of the crankshaft hole of the cylinder block of the automobile engine is high and difficult, and the known machining of the crankshaft hole of the cylinder block is processed by a horizontal boring machine, and the machining accuracy is difficult to meet the requirements. Practice has proved that only the vertical honing machine can guarantee the machining accuracy of the crankshaft hole. When machining the crankshaft hole of the cylinder block, the loading, processing and unloading processes are all automatically conveyed. The operation is stable, and the bottom surface is used as the conveying surface, so the cylinder block must be turned 90 degrees to make the processing hole and the grinding head in the same direction.
发明内容Contents of the invention
本实用新型所要解决的技术问题是：提供一种汽车发动机气缸体曲轴孔加工翻转夹具，能使汽车发动机气缸体自由翻转90度。The technical problem to be solved by the utility model is: to provide an automobile engine cylinder block crankshaft hole machining turning over jig, which can make the automobile engine cylinder body freely turn over 90 degrees.
本实用新型解决其技术问题所采用的技术方案是：本实用新型由第一油缸、第一活塞杆、压板、定位销、第二活塞杆、第二油缸、转轴和夹具本体组成，其特征是：夹具本体上有第一油缸、第二油缸，第一油缸内有第一活塞杆，第一活塞杆和压板相连，第二油缸内有第二活塞杆，第二活塞杆和定位销相连，转轴和夹具本体相连。The technical solution adopted by the utility model to solve its technical problems is: the utility model is composed of a first oil cylinder, a first piston rod, a pressure plate, a positioning pin, a second piston rod, a second oil cylinder, a rotating shaft and a fixture body, and is characterized in that : There is a first oil cylinder and a second oil cylinder on the fixture body, there is a first piston rod in the first oil cylinder, the first piston rod is connected with the pressure plate, there is a second piston rod in the second oil cylinder, and the second piston rod is connected with the positioning pin, The rotating shaft is connected with the fixture body.
由于采用上述技术方案，本实用新型所具有的优点和积极效果是：结构简单，装卸气缸体方便，提高了工作效率。Due to the adoption of the above technical proposal, the utility model has the advantages and positive effects: simple structure, convenient loading and unloading of the cylinder body, and improved work efficiency.
