Abstract

The utility model relates to a scratch-proof processing center sleeve for a mandrel, which comprises a metal sleeve and bolts mounted on the wall of the metal sleeve radially and evenly in a meshed manner. A cushion is mounted on the inner surface of the tail of each bolt, and the sleeve is sleeved on the mandrel at a support position of a small rail car, so that coaxiality of the mandrel during processing can be adjusted more effectively, the surface of the mandrel is ensured not to be scratched, and the production quality of the mandrel is improved.

Description

Plug anti-scratch machining center cover
Technical field
The utility model belongs to field of machining, relates to the machining of plug, especially a kind of plug anti-scratch machining center cover.
Background technology
Plug mainly is to be used at the parts of pressing direction at the mould of pressed compact or sintered body internal shaping contoured surface; Belong to long axis workpiece; It is the warp tool in the seamless steel tube production; Length is longer, and is under the most evil bad condition of high temperature, high pressure, to work, and therefore requires the very high especially axiality of technical conditions of plug processing and fabricating to have relatively high expectations.At present, the coaxial processing of existing plug need be provided with a plurality of small rail cars and support on guide rail, the axiality of lathe is guaranteed the axiality of plug processing with small rail car.But the same axial adjustment of small rail car is comparatively loaded down with trivial details; And the blank axiality of plug is relatively poor; Small rail car scratches mandrel surface easily in the process that clamps the plug blank simultaneously, and therefore not only production efficiency is low for present this processing mode, and is difficult to guarantee the quality of plug working axiality.
Summary of the invention
The purpose of the utility model is to overcome the weak point of prior art; A kind of plug anti-scratch machining center cover that is installed in track vehicle frame supporting-core rod position is provided; This center can satisfy the working axiality of plug; Guarantee that simultaneously mandrel surface is not scratched, improve the quality and the speed of plug processing.
The purpose of the utility model is achieved in that
A kind of plug anti-scratch machining center cover; Comprise a metal sleeve and bolt; It is characterized in that: radial equipartition construction bolt on the metal sleeve tube wall, this bolt engagement is installed on the metal sleeve tube wall this bolt end mounted on surface one cushion in metal sleeve.
And said bolt axially spaced-apart on the metal sleeve tube wall is equipped with two groups, and every group of bolt is uniformly distributed with on same diametric plane installs 4~8.
The advantage and the good effect of the utility model are:
1, this plug anti-scratch machining center cover; The bolt radial equipartition is installed on the metal sleeve, and casing pipe sleeve is contained on the plug of small rail car support zone, at this bolt tail end mounted on surface one cushion; Make in the process of plug processing; Can regulate the axiality of plug processing, guarantee also that simultaneously mandrel surface is not scratched, and improves the quality that plug is produced.
2, this plug anti-scratch machining center cover; The bolt radial equipartition is installed on the metal sleeve, at this bolt tail inner surface one cushion is installed, design science is reasonable; Make plug in the process of processing; Can regulate the axiality of plug processing quickly and easily, and plug is firmly fixed more, improve the production efficiency of producing plug.
Description of drawings
Fig. 1 is the structural front view of the utility model;
Fig. 2 is the side view of Fig. 1;
Fig. 3 is that the A-A of Fig. 2 is to cross-sectional view.
The specific embodiment
Below in conjunction with accompanying drawing the embodiment of the utility model is done further detailed description, present embodiment is descriptive, is not determinate, can not limit the protection domain of the utility model with this.
A kind of plug anti-scratch machining center cover comprises a metal sleeve 1 and bolt 2, radial equipartition engagement construction bolt on the metal sleeve tube wall, this bolt tail end mounted on surface one cushion 3 in metal sleeve.In the present embodiment, this bolt metal sleeve axially on be equipped with two groups at interval; Every group of dog screw is uniformly distributed with on same diametric plane installs four, also can install four to eight as required.
The method for using of the utility model is:
Metal sleeve is sleeved on the plug of small rail car support zone; Plug is contacted with cushion; Guarantee that plug is not scratched by bolt; Can guarantee the axiality of plug processing through the axiality that guarantees sleeve pipe and lathe, and adopt bolt to regulate the height of plug, to adapt to the plug of different-diameter.

Claims (2)

1. plug anti-scratch machining center cover; Comprise a metal sleeve and bolt; It is characterized in that: radial equipartition construction bolt on the metal sleeve tube wall, this bolt engagement is installed on the metal sleeve tube wall this bolt end mounted on surface one cushion in metal sleeve.
2. plug anti-scratch machining center cover according to claim 1 is characterized in that: said bolt axially spaced-apart on the metal sleeve tube wall is equipped with two groups, and every group of bolt is uniformly distributed with on same diametric plane installs 4~8.
