Abstract
The invention relates to a fixture of a cylindrical shaving core shaft with a shoulder. The fixture is characterized by comprising a shaving core shaft, spacing sleeves and nuts, wherein the shaving core shaft is a step cylinder with a shoulder, an installation part is arranged on one side of the shoulder, one spacing sleeve, a workpiece and the other spacing sleeve are installed on the shaving core shaft in sequence on the other side of the shoulder, and the spacing sleeves are fastened by the nuts, so as to clamp the workpiece. According to the fixture, the cylindrical shaving core shaft with the shoulder is in clearance fit with an inner hole of the workpiece, and the spacing sleeves are fastened by the nuts, so as to clamp the workpiece, so that the inner hole of the workpiece is prevented from being damaged, the core shaft is prevented from being burnt, the labor intensity is reduced, the working efficiency is improved, and the processing precision of the workpiece is guaranteed.
Description
Technical field
The design relates to a kind of band shoulder cylinder shaving dabber clamp, belongs to machining technique field.
Background technology
Gear shaving adds man-hour, usually utilizes conical core shaft tensioner two endoporus, effectively can ensure the axiality of workpiece reference for assembling and machining benchmark, and provides good end standard for later process.But need when using conical core shaft by real for workpiece pier, clamping on anvil iron, not only work efficiency is low, labour intensity large, and easy damaged inner hole of workpiece and " ablation " mandrel, cause positioning precision to decline.Add mandrel top two on positioning and rigid poor, when therefore processing tooth base end face and circular runout all comparatively large, thus affect following process.
Summary of the invention
For the deficiencies in the prior art, the object of the design is to provide a kind of band shoulder cylinder shaving dabber clamp, adopt band shoulder cylinder shaving mandrel and inner hole of workpiece matched in clearance, by fastening nuts spacer thus clamping work pieces, structure is simple, avoids disfiguring workpiece endoporus and " ablation " mandrel, reduces labour intensity, not only increase work efficiency, and ensure that the machining accuracy of workpiece.
For achieving the above object, the design is realized by following technological means:
A kind of band shoulder cylinder shaving dabber clamp, it is characterized in that: comprise shaving mandrel, spacer, nut, described shaving mandrel is band shoulder stepped cylindrical, shoulder while be installation portion, the another side of shoulder is provided with spacer, workpiece, spacer successively on shaving mandrel, by fastening nuts spacer thus clamping work pieces.
Further:
Described one band shoulder cylinder shaving dabber clamp, is characterized in that: adopt matched in clearance between described workpiece and shaving mandrel.
Described one band shoulder cylinder shaving dabber clamp, is characterized in that: between described workpiece and shaving mandrel, fit tolerance is H6/h5.
Described one band shoulder cylinder shaving dabber clamp, is characterized in that: between described workpiece and shaving mandrel, fit tolerance is H7/h6.
Described one band shoulder cylinder shaving dabber clamp, is characterized in that: between described workpiece and shaving mandrel, fit tolerance is H8/h9.
Described one band shoulder cylinder shaving dabber clamp, it is characterized in that: described shaving mandrel length is 195mm, the diameter of shaving mandrel installation portion is 40mm.
The invention has the beneficial effects as follows: the design adopts band shoulder cylinder shaving mandrel and inner hole of workpiece matched in clearance, by fastening nuts spacer thus clamping work pieces, avoid disfiguring workpiece endoporus and " ablation " mandrel, reduce labour intensity, not only increase work efficiency, and ensure that the machining accuracy of workpiece.
