Abstract
The invention discloses an external grinding mandrel of a piston pin. The external grinding mandrel of the piston pin comprises a mandrel locating shaft (1), a gasket (3) and a locating sleeve (4), wherein the mandrel locating shaft (1) is fixedly arranged on the locating sleeve (4) through a nut (2) and the gasket (3) by penetrating through an inner hole of the piston pin. According to the external grinding mandrel of the piston pin, disclosed by the invention, the installing and the clamping of a grinding machine are convenient, the end surface of the piston pin cannot be damaged, thus the size of the piston pin can be met, the quality can be ensured, a tool can be accurately located, the piston pin can be erected by the tail part of the grinding machine as the mandrel locating shaft is provided with a central hole, the coaxiality of the inner hole and the external circle of the piston pin are ensured during processing, and over-size vibrating and bouncing during processing are avoided at the same time.
Description
Technical field
The present invention relates to a kind of piston pin external grinding mandrel.
Background technology
In prior art, the tool structure complexity of mill piston pin cylindrical, during work, be not easy location, causes this frock accurately not locate, and affects grinding quality.
Summary of the invention
The purpose of this invention is to provide a kind of tool locating piston pin external grinding mandrel accurately.
The technical scheme that the present invention adopted for achieving the above object is: a kind of piston pin external grinding mandrel, comprise axle locating shaft (1), packing ring (3) and positioning sleeve (4), described axle locating shaft (1) is fixed on positioning sleeve (4) by nut (2) and packing ring (3) through gudgeon pin bore.
A kind of piston pin external grinding mandrel of the present invention, being convenient to grinding machine is installed, and do not injure the piston pin end face, thereby meet the piston pin size, guaranteed quality, this tool locating is accurate, because on the axle locating shaft, centre bore is arranged, being installed holds out against afterwards with tail seat of grinding machine, adds the endoporus that guarantees piston pin man-hour and the axiality of cylindrical, avoided adding the vibrations in man-hour simultaneously, beated excessive.
The accompanying drawing explanation
Fig. 1 is the structural representation of a kind of piston pin external grinding mandrel of the present invention.
In figure: 1, axle locating shaft; 2, nut; 3, packing ring; 4, positioning sleeve.
The specific embodiment
As shown in Figure 1, the piston pin external grinding mandrel, comprise axle locating shaft 1, packing ring 3 and positioning sleeve 4, axle locating shaft 1 is fixed on positioning sleeve 4 by nut 2 and packing ring 3 through gudgeon pin bore, a kind of frock of refining the piston pin cylindrical of this piston pin external grinding mandrel, mainly utilize the inner bore chamfering location of piston pin both sides, at first axle locating shaft 1 is passed from gudgeon pin bore one side, at opposite side, with positioning sleeve 4, withstand, the rear fastening nut 2 of cover upper gasket 3, a kind of piston pin external grinding mandrel of the present invention, being convenient to grinding machine is installed, and do not injure the piston pin end face, thereby meet the piston pin size, guaranteed quality, this tool locating is accurate, because on the axle locating shaft, centre bore is arranged, be installed and hold out against with tail seat of grinding machine afterwards, add the endoporus that guarantees piston pin man-hour and the axiality of cylindrical, the vibrations in man-hour have been avoided adding simultaneously, beat excessive.
