Abstract
The utility model relates to a grinding head for center holes, comprising a grinding bar and a grinding head. The technical points are that: the grinding bar is provided with a base and a jointed rod which are rigidly arranged as a whole; a T-shaped grinding wheel is used as the grinding head which is fixed by the gland at the front end of the base; the head cone of the grinding wheel is the same as the cone of the center hole of the processed work pieces. The utility model has the advantages of reasonable design, convenient operation, precise error correction of the center holes in the axis work pieces of the deformed center holes which are deformed after heat treatment or long uses core shafts, and improvement of positioning datum of the center holes and quality of the processed work pieces.
Description
Technical field
The utility model relates to a kind of special-purpose grinding tool, particularly a kind of centre bore bistrique that is exclusively used in reconditioning shaft-like workpiece location benchmark.
Background technology
At present, shaft-like workpiece adds man-hour on plain external grinding machine and universal grinding machine external, utilizes chuck and stationary center to be supported on the centre bore at workpiece two ends.During grinding, top with the workpiece rotation, but the conical surface in workpiece centre hole rotates around the conical surface of stationary center.Centre bore is the location benchmark of workpiece, and the form and position tolerance precision of its conical surface directly influences the crudy of workpiece.Workpiece after heat treatment will produce distortion generally speaking, and the centre bore error of its axle head will influence the crudy of workpiece, and the centre bore after the heat treatment normally can't be with cutting element processing, have to be as waste disposal.In addition, the long-term mandrel centre bore easy deformation of using, its excircle can not be reprocessed, and scraps for not making it, need repair again the centre bore of one end and could continue to use.But revise the location benchmark of centre bore again, adopt conventional processing method to revise centre bore.
The utility model content
The purpose of this utility model provides a kind of centre bore bistrique, its reasonable in design, easy to use, can revise the error of shaft-like workpiece centre bore that deforms after the heat treatment or use the center of deformation hole of mandrel for a long time exactly, improve the location benchmark of centre bore and the quality of workpiece to be machined.
The purpose of this utility model is achieved in that this device comprises mill bar and bistrique, its technical essential is: described mill bar constitutes by installing all-in-one-piece pedestal and extension bar, the front end of pedestal utilizes gland, and fixedly the T-shape emery wheel is as bistrique, and the head conical surface of emery wheel is identical with the processed workpiece centre hole conical surface.
Because the utility model is assembled in the T-shape emery wheel head conical surface of the pedestal front end bistrique of mill bar, identical with the processed workpiece centre hole conical surface, can at an easy rate the extension bar that grinds bar be assembled in the grinding machine spindle hole, utilize emery wheel that grinding is revised in the workpiece centre hole, so its reasonable in design, easy to use, the error of shaft-like workpiece centre bore that deforms after the heat treatment or use the center of deformation hole of mandrel for a long time be can revise exactly, the location benchmark of centre bore and the quality of workpiece to be machined improved.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is a kind of concrete structure schematic diagram of the present utility model.
The specific embodiment
Describe concrete structure of the present utility model in detail according to Fig. 1.This device comprises mill bar and bistrique, wherein grinds bar by installing all-in-one-piece pedestal 3 and extension bar 4 constitutes.Pedestal 3 and extension bar 4 can utilize interference fit to link together, and fix with pin again, also can utilize other fit system that pedestal 3 and extension bar 4 are loaded into one.The pedestal 3 of mill bar and specification, the shape of extension bar 4 should conform to specification, the shape in employed grinding machine spindle hole.The front end of pedestal 3 utilizes gland 2, and fixedly T-shape emery wheel 1 is as bistrique, and the head conical surface of emery wheel 1 is identical with the processed workpiece centre hole conical surface.
After revising heat treatment, deform or when using the error of shaft-like workpiece centre bore in center of deformation hole of mandrel for a long time, with workpiece with special purpose chuck or centre frame centering, also available stationary center or special-purpose clamp support, and can utilize the bistrique of clamping in the grinding machine spindle hole that reconditioning has been carried out in the workpiece centre hole.
Claims (1)
1, a kind of centre bore bistrique, comprise mill bar and bistrique, it is characterized in that: described mill bar constitutes by installing all-in-one-piece pedestal and extension bar, and the front end of pedestal utilizes fixedly T-shape emery wheel of gland, and the head conical surface of emery wheel is identical with the processed workpiece centre hole conical surface.
