Abstract

The utility model discloses a mandrel penetrating assembly used for a grinding machine, which comprises a mandrel, wherein two glands, a check ring and a nut are sequentially sleeved on the mandrel; a gap is arranged between the two glands; small end faces of the two glands correspond to each other; a big end face of one gland leans against the flange of the mandrel; and the other gland, the check ring and the nut are sequentially attached. In the utility model, the mandrel penetrating assembly has a simple structure and is arranged on an excircle grinding machine for machining external diameter surfaces of a group of loops, the workpiece handling time is saved, the machining efficiency is greatly improved, and the size consistency of the whole group of loops is ensured.

Description

A kind of grinding machine punching shaft assembly

Technical field

The utility model belongs to the machining equipment technical field, relates to the frock jig of the outer diametric plane of a kind of cylindrical grinder grinding bearing lasso, especially relates to a kind of grinding machine punching shaft assembly.

Background technology

At present, outside the machining large bearing ring during diametric plane, bearing industry often adopts centerless grinder to process, because centerless grinder adopts the electric magnetic no-core jig, the part that at every turn can only be installed carries out grinding, therefore the outer diametric plane of lasso of every grinding, will carry out that a subjob is installed, the workpiece dismounting after lathe adjustment and the completion of processing, had a strong impact on working (machining) efficiency, and because the deviation that each workpiece is installed and lathe is adjusted causes easily also the dimensional uniformity of a collection of part relatively poor.Though adopt centerless grinder processing lasso can obtain higher circularity, but when the not high outer diametric plane of large-scale bearing ring of some required precisions of processing in enormous quantities, as process the outside dimension scope outside the large-scale turntable bearing lasso of 200mm ~ 320mm during diametric plane, lasso circularity is less demanding, and be to produce in enormous quantities, it is very unfavorable adopting centerless grinder processing.

Summary of the invention

For addressing the above problem, the purpose of this utility model provides a kind of grinding machine punching shaft assembly, is used with existing cylindrical grinder, processes in enormous quantities, the outer diametric plane of the less demanding large-scale bearing ring of the accuracy of form and position.

For achieving the above object, the utility model adopts following technical scheme:

A kind of grinding machine punching shaft assembly, it comprises mandrel and is sleeved on two glands, back-up ring and nuts on the mandrel successively, between two glands spacing is arranged, the small end face of two glands is corresponding, the large end face of one of them gland abuts against on the rib of mandrel, and another gland, back-up ring and nut are close to successively.

Owing to adopt aforesaid technical scheme, the utlity model has following superiority:

This grinding machine punching shaft assembly, it is simple in structure, reasonable in design, when being installed on the cylindrical grinder the outer diametric plane of processing lasso, be installed at every turn, can process one group of lasso, saved piece handling time, greatly improve working (machining) efficiency, because of having reduced workpiece the deviation that causes has been installed simultaneously, guaranteed the dimensional uniformity of whole group of lasso preferably.

Description of drawings

Fig. 1 is a structural representation of the present utility model;

Among the figure: the 1-mandrel; 2(a, b)-gland; The 3-lasso; The 4-nut; The 5-back-up ring.

The specific embodiment

Below by drawings and Examples the technical solution of the utility model is described in further detail.

As shown in Figure 1, this grinding machine punching shaft assembly, it comprises mandrel 1 and is sleeved on two glands, back-up ring 5 and nut 4 on the mandrel successively, between two glands spacing is arranged, the small end face of two glands is corresponding, the large end face of one of them gland 2a abuts against on the rib of mandrel 1, several lassos 3 are installed in series on mandrel 1, between two glands and with the small end face of two glands near, back-up ring 5 abuts against on another gland 2b, fastening by nut 4, guarantee that the lasso that assembles can play on mandrel is axial.

Grinding machine determines according to the part to be processed size with punching shaft assembly size, and the maximum part to be processed quantity that can be installed between two glands is determined according to the performance and the actual needs of supporting grinding machine.

After the assembling of above-mentioned punching shaft assembly finishes, be installed in grinding machine forward and backward top between, adjust grinding machine, can carry out grinding.

Claims

1. grinding machine punching shaft assembly, it is characterized in that: it comprises mandrel and is sleeved on two glands, back-up ring and nuts on the mandrel successively, between two glands (2a, 2b) spacing is arranged, the small end face of two glands is corresponding, the large end face of one of them gland (2a) abuts against on the rib of mandrel (1), and another gland (2b), back-up ring (5) and nut (4) are close to successively.
