Description

A kind of dedicated follow-rest of elongated bar stock processing
Technical field
The utility model relates to follow-rests, in particular to a kind of elongated bar stock to process dedicated follow-rest.
Background technique
In turning slender piece on lathe, the clamped slender piece in both ends can be because of gravity if intermediate lack support Effect generates naturally flexure, and this scratches the joint performance of quyi in turning process because centrifugal force is amplified, it is easy to be deformed, shake It is dynamic, so that workpiece size and precision are difficult to ensure, therefore often increase corresponding auxiliary mould on the planker on lathe, also It is follow-rest.Follow-rest is the auxiliary device of radial support rotational workpieces.When processing, moved axially together with cutter along workpiece. Therefore propose that a kind of elongated bar stock processes dedicated follow-rest.
Utility model content
The purpose of this utility model is to provide for a kind of dedicated follow-rest of elongated bar stock processing, the bipod of this follow-rest Span is big, and stability is good, and structure is simple, and production is simple, convenient for disassembly and assembly, and concentricity is high.
In order to achieve the above object, the utility model provides following technical solution: a kind of processing of elongated bar stock it is dedicated with Knife rest, feature include follow-rest body, spacer, locking nut, collet, interior hexagonal double-ended bolt and taper bolt;The follow-rest Body is equipped with mounting blocks;The mounting blocks are equipped with conical bore and through-hole;Follow-rest body head is equipped with centre bore;In described Heart hole is is used lathe boring pin to form;The fine crack slot across centre bore is additionally provided on the follow-rest body;The follow-rest body On be additionally provided with tapped through hole;The locking nut is equipped with checknut hole;The spacer is mounted in centre bore;The spacer The fixed locking of the tapped through hole on follow-rest body is passed through by interior hexagonal double-ended bolt;The collet is mounted in spacer;It is described Collet adjusts clamping force by locking nut.
It is further preferred that the shape of the tool-post structure is herringbone.
The utility model has the beneficial effects that the bipod span of the follow-rest is big, stability is good, and structure is simple, and production is simple, Convenient for disassembly and assembly, concentricity is high and structure is more small and exquisite, saves processing space, easily arranges knife.

Specific embodiment
We make further a kind of dedicated follow-rest of elongated bar stock processing described in the utility model in conjunction with attached drawing below Explanation.
As shown in figs. 1-4, a kind of elongated bar stock of the present embodiment processes dedicated follow-rest, and feature includes follow-rest body 1, spacer 2, locking nut 3, collet 4, interior hexagonal double-ended bolt 5 and taper bolt 6;The follow-rest body 1 is equipped with mounting blocks 7; The mounting blocks 7 are equipped with conical bore 72 and through-hole 71;1 head of follow-rest body is equipped with centre bore 11;The centre bore 11 For formed using lathe boring pin;The fine crack slot 12 across centre bore 11 is additionally provided on the follow-rest body 1;The follow-rest body Tapped through hole 13 is additionally provided on 1;The locking nut 3 is equipped with checknut hole 31;The spacer 2 is mounted on centre bore 11 It is interior;The spacer 2 passes through the fixed locking of the tapped through hole 13 on follow-rest body 1 by interior hexagonal double-ended bolt 5;The collet 4 It is mounted in spacer 2;The collet 4 adjusts clamping force by locking nut 3;The shape of the follow-rest body 1 is herringbone Shape.
In the present embodiment installation process, through-hole 71 and conical bore are passed through using two interior hexagonal double-ended bolts 5 and taper bolt 6 first 72 are installed to follow-rest body 1 on the big palette on lathe, then process centre bore 11 by the machine main shaft boring, and stamp Positioning pin (concentricity that can guarantee main-shaft core Yu knife rest center in this way);Then remove follow-rest body 1, by wire cutting plus After the completion of work fine crack slot 12, positioning first is stamped with the pin hole that hexagon socket cap head screw 5 is fixed on big palette and before basis Pin passes through tapped through hole 13 with interior hexagonal double-ended bolt 5 and drives with knife then by the plug of spacer 2 into the centre bore 11 on follow-rest body 1 Collet 4 is filled in spacer 2 and adjusts 4 clamping force size of collet with locking nut 3 by 1 locking spacer 2 of frame body, and Loosening on locking nut 3 steps up to follow closely screw check in threaded hole 31;Follow-rest is installed.
Beneficial effect caused by the utility model, since 1 shape of follow-rest body is set as herringbone, the follow-rest Bipod span it is big, stability is good, and structure is simple, and production is simple, and convenient for disassembly and assembly, follow-rest body 1 is processed by the machine main shaft boring Centre bore 11 out, and positioning pin is stamped, it can guarantee the concentricity of main-shaft core and follow-rest center, therefore concentricity in this way It is high;Since structure is more small and exquisite, saves processing space, easily arranges knife.
The protection scope of the utility model is not limited to above embodiments and its transformation.Those skilled in that art are with this implementation The conventional modification and replacement carried out based on the content of example, belongs to the protection category of the utility model.
