Tool for four-axis four-station machining center

Abstract

The invention provides a tool for a four-axis four-station machining center. The tool comprises a bottom plate, a tailstock and a headstock, the tailstock and the headstock are mounted on the bottom plate through bolts, a tailstock L-shaped plate and a headstock L-shaped plate are arranged on the tailstock and the headstock correspondingly, a bridge plate is arranged between the tailstock L-shaped plate and the headstock L-shaped plate, and a positioning plate is arranged on the bridge plate; an oil cylinder is arranged between the bridge plate and the bottom plate, an ejector rod is arranged on the oil cylinder, and the ejector rod is connected with a pressing rod through a connecting pin; and an oil separator is further arranged on the tailstock and connected with the oil cylinder through an oil pipe. According to the tool, a hydraulic system is adopted, four-station machining is achieved, one person can machine multiple machines, and efficiency is improved; a pneumatic system is changed into a hydraulic system, the maximum pressure of the pneumatic system is 0.8 MP, and the actual use pressure of the pneumatic system is 0.6 MP; after the pneumatic system is changed into the hydraulic system, the pressure of the system is 2.5 MP and is more than four times that of the pneumatic system, that is, the system obtains the same clamping force as that of a pneumatic clamping cylinder, and the piston area of a hydraulic cylinder is 1 / 4 of that of a pneumatic cylinder, so that the space is reduced, the length of the bridge plate is prolonged, and the clamping space is increased.

Description

technical field [0001] The present invention relates to the field of mechanical processing, in particular to the field of processing small general-purpose gasoline engine cylinder blocks, specifically a tooling for a four-axis four-station machining center. Background technique [0002] There are usually two processing methods for spark plug holes, intake and exhaust holes, and installation through holes on the cylinder block of a small general-purpose gasoline engine: special machine drilling or drilling center drilling. The drilling and tapping center has good flexibility, quick replacement, high reliability, high efficiency, and consistent quality of the processed cylinder block, which is the first choice of processing enterprises at present. The processing space of the drilling and tapping center is generally 500X400X300, and the processing space is even narrower after being equipped with four axes. Therefore, how much the four-axis tooling clamps the cylinder block at ...
