Abstract
The utility model discloses a can push up and to draw formula lathe tailstock structure belongs to lathe device field for the processing of lathe major axis class work piece, it includes power unit, tailstock dabber, bearing, main shaft and chuck, wherein power unit passes through the tailstock dabber and is connected with the main shaft, is equipped with the chuck on the main shaft, bearing position is in the junction of tailstock dabber and main shaft. In view of above -mentioned technical scheme, the utility model discloses can realize the processing of longer axle type work piece, avoid in the course of working work piece to take place to tremble, crack etc. Improve the processing finished product rate of longer axle class work piece.
Description
Technical field
This utility model belongs to lathe accessories field, specifically, particularly relates to one and can push up pullable type tail stock structure.
Background technology
The Main Function of existing tail stock assembly is to be held out against by the workpiece needing processing, and the machining long workpieces of countershaft class adds
Man-hour requirement uses auxiliary chuck by fixing for workpiece with the rigidity strengthening this type of workpiece, it is simple to processing.But in actual production process
In, the machining long workpieces of axle class, when being machined to centre position, easily makes workpiece produce chatter mark；Same in the course of processing, due to
Axle class machining long workpieces can generate heat elongation in the course of processing, workpiece bows occurs under the effect that holds out against of tail stock, more exacerbates work
Trembling of part, causes the generation of waste product.
Utility model content
The purpose of this utility model is to provide one can push up pullable type tail stock structure, and it is capable of longer axis class workpiece
Processing, it is to avoid in the course of processing, workpiece trembles, cracks, improves the processed finished products rate of longer axis class workpiece.
For reaching above-mentioned purpose, this utility model is achieved through the following technical solutions:
Described in the utility model push up pullable type tail stock structure, including actuating unit, tailstock mandrel, bearing, main shaft and
Chuck, wherein actuating unit is connected with main shaft by tailstock mandrel, and main shaft is provided with chuck, described bearing be positioned at tailstock mandrel and
The junction of main shaft.
Saying further, main shaft described herein is provided with gland with the gap of bearing.
Saying further, actuating unit described herein is connected with tailstock mandrel by piston.
Saying further, bearing described herein uses angular contact ball bearing.
Saying further, actuating unit described herein is hydraulic jack or pneumatic oil cylinder.
Compared with prior art, the beneficial effects of the utility model are:
This utility model can process long-axle workpieces, such as the slender axles of 35:1, gets rid of long-axle workpieces because occurring in the course of processing
The workpiece bows caused by thermal stretching, reduces and is machined to the seminess of trembling that during middle section position, this type of workpiece occurs, improves product
Yield rate.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1, chuck；2, main shaft；3, bearing；4, tailstock mandrel；5, piston；6, actuating unit；7, gland.
Detailed description of the invention
Below in conjunction with the accompanying drawings and technical scheme described herein is described further by embodiment.
Embodiment 1: one can push up pullable type tail stock structure, including actuating unit 6, tailstock mandrel 4, bearing 3, main shaft
2 and chuck 1, wherein actuating unit 6 is connected with main shaft 2 by tailstock mandrel 4, and main shaft 2 is provided with chuck 1, described bearing
3 junctions being positioned at tailstock mandrel 4 and main shaft 2.
Embodiment 2: one can push up pullable type tail stock structure, including actuating unit 6, tailstock mandrel 4, bearing 3, main shaft
2 and chuck 1, wherein actuating unit 6 is connected with main shaft 2 by tailstock mandrel 4, and main shaft 2 is provided with chuck 1, described bearing
3 junctions being positioned at tailstock mandrel 4 and main shaft 2.Described main shaft 2 is provided with gland 7 with the gap of bearing 3.Described engine
Structure 6 is connected with tailstock mandrel 4 by piston 5.Described bearing 3 uses angular contact ball bearing.Described actuating unit 6 is hydraulic pressure
Oil cylinder or pneumatic oil cylinder.
In view of above-described embodiment, long-axle workpieces in use, is clamped by chuck 1, and passes through main shaft by this utility model
2, long-axle workpieces is strained or holds out against action by tailstock mandrel 4 and actuating unit 6, overcomes original lathe back stand mechanism to length
Shaft-like workpiece carries out merely the workpiece bows that the effect that holds out against causes and then the mistake thermal stretching phenomenon increasing the weight of appearance in the course of processing, thus
Avoid in this type of workpiece process occur tremble and seminess.
Bearing 3 is for supports main shaft 2 and the revolution of chuck 1.Being provided with gland 7 between bearing 3 and main shaft 2, gland 7 is used for
Eliminate the gap between bearing 3, and bearing 3 is fixed in tailstock mandrel 4.Tailstock mandrel 4 can be slided in tailstock body back and forth
Dynamic, to coordinate actuating unit 6 complete the tension of workpiece and unclamp the actions such as workpiece.
