Abstract

The utility model discloses a composite support applicable to a vertical grinder for grinding large-size rotating bearings, which consists of a plurality of composite support bodies. Two sides of each composite support body are fixed onto an electromagnetic sucker by T-shaped screws, T-shaped grooves are radially distributed on the electromagnetic sucker, and the composite support bodies can slide along the T-shaped grooves. By means of uniformly adopting a group of magnetic-permeable composite bodies, secondary adjustment is omitted when inner rings and outer rings are machined, simultaneously uniform reference of the composite support bodies needs to be self-ground at a time, and the composite support applicable to the vertical grinder for grinding large-size rotating bearings not only improves work efficiency, but also guarantees machining precision, is simple and compact in structure, convenient in machining and manufacturing, high in precision and long in service life, and brings great convenience for batch production.

Description

A kind of huge revolving bearing grinding that is applied to vertical grinder is used composite support

Technical field

The utility model relates to a kind of composite support device, relates in particular to a kind of huge revolving bearing grinding that is applied to vertical grinder and uses composite support, belongs to field of machining.

Background technology

When the huge revolving bearing enclose was distinguished grinding on vertical grinder, installation way generally adopted the magnetic holding device location.Existing anchor clamps all adopt simple magnetic inductive block locating element as rest pad, according to its relative position on sucker of size adjustment of part radial dimension, utilize emery wheel clamping parts behind its bearing-surface of autogenous grinding on the lathe again.

The shortcoming of this structure is: magnetic inductive block is that the size according to single component designs its width dimensions; The Internal and external cycle radial dimension that one cover gyroaxis holds is different; In order to guarantee that its geometric accuracy generally all requires on same lathe, to process, like this, during difference grinding Internal and external cycle; Just must readjust magnetic conduction rest pad position on sucker, also autogenous grinding again after mixing up.

On the one hand, because the rest pad number is more, generally have more than 16; Readjust and take time and effort, on the other hand, need the supporting of autogenous grinding again end face after the adjustment; Cause floating bearing Internal and external cycle height inconsistent, cause mismachining tolerance easily, influence production efficiency and machining accuracy.

The utility model content

The technical problem that the utility model will solve is to overcome existing defective, improves the operating accuracy and the stability of grinding machine, and a kind of composite support that is used for the huge revolving bearing grinding is provided.

A kind of huge revolving bearing grinding that is applied to vertical grinder of the utility model is used composite support, and following technical scheme is provided:

A kind of huge revolving bearing grinding that is applied to vertical grinder is used composite support; Comprise rest pad; Constitute one group of composite support by a plurality of composite supports; The composite support both sides are fixed on the magnechuck through T type screw, and the magnechuck upper edge is radially distributed with T-slot, and composite support can slide along T-slot.

Further, the composite support width is the width of floating bearing Internal and external cycle fitted position.

A kind of huge revolving bearing grinding that is applied to vertical grinder of the utility model is used composite support, and the width of composite support is the width of floating bearing Internal and external cycle fitted position, and mounting means adopts the composite support both sides to fix with T type screw.As long as the floating bearing of Internal and external cycle fitted position overall width in the composite support width range can shared one group of composite support.

Owing to adopt unified one group of magnetic conduction composite support, when processing floating bearing Internal and external cycle, do not need twice adjustment; Simultaneously composite support is unified benchmark only needs an autogenous grinding, has not only improved operating efficiency but also guaranteed machining accuracy, and simple in structure, compact, convenient processing and manufacture, precision height and long service life are very convenient in producing use in enormous quantities.

Description of drawings

Accompanying drawing is used to provide the further understanding to the utility model, and constitutes the part of specification, is used to explain the utility model with the embodiment of the utility model, does not constitute the restriction to the utility model.In the accompanying drawings:

Fig. 1 is a kind of main sectional structure sketch map that is applied to the huge revolving bearing grinding of vertical grinder with composite support of the utility model;

Fig. 2 is a kind of local enlarged diagram that is applied to the huge revolving bearing grinding of vertical grinder with composite support of the utility model;

Fig. 3 is a kind of plan structure sketch map that is applied to the huge revolving bearing grinding of vertical grinder with composite support.

The specific embodiment

Describe below in conjunction with the preferred embodiment of accompanying drawing, should be appreciated that preferred embodiment described herein only is used for explanation and explains the utility model, and be not used in qualification the utility model the utility model.

Like Fig. 1, shown in Figure 2, according to the external diameter location dimension Ф D of floating bearing outer ring 1, and the internal diameter radial location size Ф d of floating bearing inner ring 2, the position width that calculates composite support 3 is (Ф D-Ф d)/2.

As shown in Figure 3, choose 20 composite supports 3 as one group, composite support 3 is placed in the T-slot 5 that radially has on the magnechuck 4.Again according to Internal and external cycle drawing size, the T type groove 5 of one group of composite support 3 through magnechuck 4 be adjusted to make the position that Internal and external cycle can both be supported, fix in composite support 3 both sides with T shape screw.

Through the upper surface of emery wheel autogenous grinding composite support 3, to guarantee its supporting plane positioning accuracy, carrying out clamping parts then is floating bearing on lathe, and part is just inhaled on sucker behind the last magnetic, thereby can carry out grinding to the part relevant surfaces.

Adopt the composite support of this design, can satisfy Internal and external cycle and under the situation that composite support does not move, can both distinguish any processing.Accomplish clamping No. one time, use repeatedly, not only improved operating efficiency but also guaranteed machining accuracy, simple in structure, compact, convenient processing and manufacture, precision height and long service life, very convenient in producing use in enormous quantities.

The above is merely the preferred embodiment of the utility model; Be not limited to the utility model; Although the utility model has been carried out detailed explanation with reference to previous embodiment; For a person skilled in the art, it still can be made amendment to the technical scheme that aforementioned each embodiment put down in writing, and perhaps part technical characterictic wherein is equal to replacement.All within the spirit and principle of the utility model, any modification of being done, be equal to replacement, improvement etc., all should be included within the protection domain of the utility model.
