Abstract

The utility model belongs to the technical field of machine tools, and discloses a chuck for a lathe tailstock. According to the technical scheme, the chuck comprises a tailstock chuck body, a flange plate, a taper shank, locking bolts, a bolt support and a tailstock sleeve, the end with the larger diameter of the taper shank is coaxially connected with the tailstock chuck body through the flange plate, the end with the smaller diameter of the taper shank is in rotary connection with the lathe tailstock, the outer portion of the taper shank is loosely sleeved with the tailstock sleeve, the tailstock sleeve is fixedly connected with the lathe tailstock, the bolt support is fixed to the flange plate, the locking bolts are screwed in threaded holes in the bolt support, and the ends of the locking bolts abut against the side wall of the tailstock sleeve. The tailstock chuck body is used for clamping workpieces, the defect that two ends of long and thin workpieces need to be aligned is overcome, the machining efficiency of the thin-wall workpieces and the long and thin workpieces is greatly improved, the workpieces can be effectively prevented from vibrating when the outer circles of the thin-wall workpieces are machined, and therefore the machining precision of the workpieces and operation safety are guaranteed. In addition, the chuck further has the advantages of being simple in structure, low in cost, convenient to mount and maintain and the like.

Description

A kind of tail stock chuck
Technical field
The utility model relate to a kind of be arranged on tail stock for clamping the device of elongated thin-wall workpiece, belong to machine tool technology field.
Background technology
While using lathe turning workpiece, need to use fixture that workpiece is fixed on machine tool chief axis, so the performance of fixture play vital effect to the crudy of workpiece and working (machining) efficiency.Elongated thin-wall workpiece rigidity is lower, when turning, easily trembles, and is difficult for guaranteeing processing dimension, and has great potential safety hazard.The conventional method of this workpiece of turning is to use fixed mount, and processing technology comprises following 3 steps (referring to Fig. 1):
1) first on cylindrical shell right side, weld a board, centering two ends, with the top board that withstands, difference car two place's center fixed frame bands;
2) mounting center frame supports cylindrical shell, so that processing;
3) by the technological requirement successively flat both ends of the surface of car, and car one end seam.
Although can reach so predetermined turning effect, exist process complicated, the problem of long processing time, greatly reduces the working (machining) efficiency of workpiece.
Utility model content
The purpose of this utility model is the drawback for prior art, and a kind of tail stock chuck is provided, to improve the working (machining) efficiency of elongated thin-wall workpiece.
Problem described in the utility model realizes with following technical proposals:
A kind of tail stock chuck, formation comprises tailstock chuck, ring flange, taper shank, clamping screw, bolt support and barrel of tail stock, one end that described taper shank diameter is larger is coaxially connected with tailstock chuck by ring flange, one end and tail stock that its diameter is less are rotationally connected, described barrel of tail stock pine is enclosed within taper shank outside and is fixedly connected with tail stock, described bolt support is fixed on ring flange, described clamping screw is spun in the screwed hole on bolt support, and its end withstands on the sidewall of barrel of tail stock.
Above-mentioned tail stock chuck, described tailstock chuck adopts three-jaw self-centering chuck.
Above-mentioned tail stock chuck, described bolt support is the cylindrical body that is enclosed within barrel of tail stock outside, its one end is fixedly connected with ring flange, is provided with the screwed hole mating with clamping screw on its sidewall.
Above-mentioned tail stock chuck, described clamping screw arranges 3 or 4, and they are uniformly distributed around barrel of tail stock.
Above-mentioned tail stock chuck, the tapering of described taper shank is No. five taperings of Mohs.
Tailstock chuck holding workpiece for the utility model, having eliminated slender piece needs the drawback of two ends centerings, greatly improved the working (machining) efficiency of thin-wall part, elongate articles, and outside processing thin-walled bowlder, can also effectively prevent that workpiece from trembling, thereby guarantee the machining accuracy of workpiece and the security of operation.In addition, the utility model also has the advantages such as simple in structure, with low cost, installation and maintenance is convenient.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Fig. 1 is traditional clamping and loading method schematic diagram of elongated thin-wall workpiece;
Fig. 2 is structural representation of the present utility model;
Fig. 3 is that the utility model clamps workpiece schematic diagram.
In figure, each list of reference numerals is: 1, tailstock chuck, 2, ring flange, 3, taper shank (No. five, Mohs), 4, barrel of tail stock, 5, clamping screw, 6, self-aligning bearing, 7, chuck jaw, 8, spindle chuck, 9, workpiece, 10, top, 11, bolt support.
The specific embodiment
The utility model can complete the processing of cylindrical, endoporus, seam, chamfering etc. quickly and easily, can effectively solve thin-walled, the problem such as slender piece difficulty of processing is large and process is loaded down with trivial details.Its formation comprises three-jaw self-centering chuck, ring flange, taper shank (No. five, Mohs), barrel of tail stock, clamping screw.Utilize the taper shank of No. five taperings of Mohs mate with tailstock that chuck is directly loaded on tailstock, use three-jaw self-centering chuck, need not centering, use three-jaw clamping work pieces.Clamping screw is for controlling the duty (rotation or fixing) of tailstock chuck.
When the cylindrical of processing work, end face, unclamp clamping screw, tailstock chuck, in rotation status, can complete the processing of cylindrical, endoporus and chamfering.
When needing processing work endoporus, clamping screw is pressed on barrel of tail stock, tailstock chuck is fixed, for clamping drill bit, reamer or centre drill, to complete the processing in hole.
The tapering that supports the taper shank of tailstock chuck is No. five taperings of Mohs that match with tail stock, and it makes simple, easy for installation.Three-jaw self-centering chuck can with lathe under parts, taper shank can be with the taper shank of waste and old drill bit.Like this, both take full advantage of resource, reached again the object of energy-saving and emission-reduction.For some thin-wall parts, elongate articles, can avoid using the conventional machining process of fixed mount.Bowlder outside processing thin-walled, this device can also effectively prevent that workpiece from trembling.
The course of work:
By chuck jaw 7, workpiece one end is fixed, tailstock chuck 1 and ring flange 2 are fixed, self-aligning bearing 6 is equipped with in tailstock chuck 1 inside, can effectively adjust the deflection of axle class fixedly time.On ring flange 2, be furnished with clamping screw 5, when the cylindrical of processing work, end face, unclamp clamping screw 5, tailstock chuck 1 is in rotation status, to complete the processing of cylindrical, endoporus and chamfering; When needing processing work endoporus, clamping screw 5 is pressed on barrel of tail stock 4, tailstock chuck 1 is fixing, for clamping drill bit, reamer or centre drill, to complete the processing in hole.
Utilize the technical process of the utility model processing slim thin-wall workpiece:
1) tail stock self-centering chuck is installed on tail stock, with three-jaw, is propped up cylinder bore, centering scroll chuck one end;
2) by the technological requirement successively flat both ends of the surface of car, and car one end seam.
The utility model has been broken the mode of operation of traditional handicraft " folder one top " on lathe, and is expanded to " two ends clamping ", has expanded the range of work of lathe, has promoted the value of lathe.
