Abstract

The utility model belongs to lathe auxiliary field especially relates to a digit control machine tool main shaft reinforcement sleeve, its characterized in that: including reinforcement sleeve body, copper sheathing, gland, screw, dust ring, double -screw bolt, the copper sheathing install in inside the one end of reinforcement sleeve body, the gland install in the one end of reinforcement sleeve body is outside and it will the copper sheathing compresses tightly, the gland passes through the screw fastening on the reinforcement sleeve body, install the dust ring between gland, the copper sheathing, the other end of reinforcement sleeve body is provided with the fixed part, the double -screw bolt install in on the fixed part. Reinforcement sleeve plays the effect of supporting the main shaft, is equivalent to adding thick main shaft, and during the boring deep hole, the main shaft is not flagging like this, and when the main shaft rotated, the stationarity was good, the hole precision height of boring.

Description

Main shaft of numerical control machine tool reinforcing sleeve
Technical field
The utility model belongs to lathe auxiliary field, particularly relates to a kind of main shaft of numerical control machine tool reinforcing sleeve.
Background technology
The bearing block bearing hole required precision of two rollers, four-high mill is very high, and diameter is large and dark, needs boring machine to process.And existing boring machine 130 major axis diameter Φ 130mm, process some difficulty of so large dead eye, the bad guarantee of precision, because the relative shaft hole diameter of main shaft is thin, if upper boring bar bore hole main shaft stretch out oversize, in process, main shaft will produce sagging, and bore hole will cause inclination and the decentraction in hole.Therefore, be necessary to develop the precision problem in a kind of novel lathe auxiliary solution dead eye process.
Summary of the invention
The utility model, for above-mentioned technical problem, provides the main shaft of numerical control machine tool reinforcing sleeve that a kind of machining accuracy is high, cheap, operation is simple and reliable.
The technical scheme that the utility model adopts is:
A kind of main shaft of numerical control machine tool reinforcing sleeve, it is characterized in that: comprise reinforcing sleeve body, copper sheathing, gland, screw, dust ring, stud, one end that described copper sheathing is installed on described reinforcing sleeve body is inner, described gland be installed on one end of described reinforcing sleeve body outside and its described copper sheathing is compressed, described gland by screw fastening on reinforcing sleeve body, between described gland, copper sheathing, dust ring is installed, the other end of described reinforcing sleeve body is provided with fixed part, and described stud is installed on described fixed part.
Described stud is studs, and the middle part of described stud is installed on described fixed part, and the two ends of described stud are arranged at the outside of described fixed part.
Also comprise hex nut, described hex nut is installed on one end of described stud.
Described screw is hexagon socket cap head screw.
Described dust ring is A type dust ring.
The beneficial effects of the utility model are:
1, reinforcing sleeve is connected on boring spindle sleeve, by stud, hex nut close, main shaft puts in reinforcing sleeve and adopts matched in clearance with copper sheathing, operation is simple and reliable, facilitate, practical;
2, reinforcing sleeve plays the effect of supports main shaft, is equivalent to overstriking main shaft, and during such boring deep hole, main shaft is not sagging, and during main axis, stationarity is good, and the hole precision of boring is high;
3, the utility model low cost of manufacture, saving the input buying heavy duty machine tools, is the machine tool accessory that a kind of machining accuracy is high, cheap, operation is simple and reliable.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail:
In figure, 1-reinforcing sleeve body, 2-copper sheathing, 3-screw, 4-gland, 5-dust ring, 6-stud, 7-hex nut, 8-fixed part, 9-rack sleeve.
Embodiment
As shown in Figure 1, a kind of main shaft of numerical control machine tool reinforcing sleeve, comprise reinforcing sleeve body 1, copper sheathing 2, gland 4, screw 3, dust ring 5, stud 6, one end that copper sheathing 2 is installed on reinforcing sleeve body 1 is inner, gland 4 be installed on one end of reinforcing sleeve body 1 outside and its copper sheathing 2 is compressed, gland 4 is fastened on reinforcing sleeve body 1 by screw 3, is provided with dust ring 5 between gland 4, copper sheathing 2, the other end of reinforcing sleeve body 1 is provided with fixed part 8, and stud 6 is installed on fixed part 8.
Stud 6 is studs, and the middle part of stud 6 is installed on fixed part 8, and the two ends of stud 6 are arranged at the outside of fixed part 8.
Also comprise hex nut 7, hex nut 7 is installed on one end of stud 6.
Screw 3 is hexagon socket cap head screw.
Dust ring 5 is A type dust ring.
Above 1 embodiment of the present utility model has been described in detail, but described content being only preferred embodiment of the present utility model, can not being considered to for limiting practical range of the present utility model.All equalizations done according to the utility model application range change and improve, and all should still belong within patent covering scope of the present utility model.
