Abstract
The utility model relates to a tool and provides a special tool for a turning high-accuracy cylinder sleeve outer circle. The special tool comprises a taper core shaft, a locating ring, a clamping washer, a high-strength cast iron taper-lock, a sliding shaft, a supporting sleeve and a main shaft receiving disc. The supporting sleeve is connected with an oil cylinder pull rod in a sleeved mode, the taper core shaft is connected with the supporting sleeve in a sleeved mode, and the back end of the taper core shaft is fixedly connected with the main shaft receiving disc of a lathe. The locating ring is connected with the back portion of the taper core shaft in a sleeved mode, the high-strength cast iron taper-lock is connected with the taper core shaft in a sleeved mode and arranged on the front side of the locating ring, and the high-strength cast iron taper-lock does not contact the locating ring. The taper core shaft is hollow, the back end of the sliding shaft is inserted into an inner cavity at the front end of the taper core shaft, the sliding shaft is connected with the front end of the oil cylinder pull rod in a coaxial and threaded mode, and a baffle is arranged at the front end of the sliding shaft. The baffle and the clamping washer clamp a radial clamping plate of an inner cavity of the high-strength cast iron taper-lock in the middle, and the radial clamping plate is fastened through a clamping bolt. The special tool is convenient to operate, and machining accuracy and efficiency of a cylinder sleeve are improved.
Description
Technical field
Utility model relates to a kind of frock, especially a kind of turning high accuracy cylinder sleeve cylindrical special tooling.
Background technology
Along with the development of automobile industry, more and more higher to the required precision of auto parts and components, this just has higher requirement to the various technological equipments of processing this type of part.Cylinder sleeve is the important composition parts of engine, and its processing precision direct influence is to the overall utility energy of engine.The characteristics of cylinder sleeve are that cylindrical and endoporus concentricity and cylindrical circularity are had relatively high expectations, and cylinder sleeve is thin-wall part, very easily produce machining deformation and the technological problems aspect other when processing excircles, thereby cause the reduction of cylinder sleeve machining accuracy.
