Description

A kind of fixture for cutting processing for superfine shaft
Technical field
The utility model relates to machine tool technology field more particularly to a kind of fixtures that processing is cut for superfine shaft.
Background technique
There are the problems such as poor rigidity, easily-deformable for superfine shaft turnery processing, cut in processing in traditional, chucking method is general Using one top of a folder, this is easy to aggravate deformation, to influence processing quality, reduces processing efficiency.
Utility model content
In view of the above technical problems, the utility model provides a kind of fixture that processing is cut for superfine shaft, structure design It is rationally simple, the probability that superfine shaft cuts workpiece deformation in processing is reduced, processing quality and processing efficiency are improved.
To realize the above-mentioned technical purpose, the technical solution adopted in the utility model is:One kind cutting processing for superfine shaft Fixture, including by chuck, end cap, mandrel, sealing ring, bearing, spacer sleeve, nut, clamp body, tail stock, sleeve, pad Circle, bolt composition, the chuck are three-jaw self-centering chuck, and described clamp body one end is cylindrical body, which is The conical section of cone, the barrel bore shape and clamp body cooperates, and the chuck is connected by the end of flange and mandrel Integrally, the tail stock inner cavity is equipped with sleeve by screw, and the conical section of the clamp body is inserted into sleeve, and logical It crosses bolt and washer and the conical section of clamp body is fixed as one with sleeve, the tail end of the mandrel is installed there are two bearing, Two bearings pass through two nut checks, are equipped with spacer sleeve between the two bearings, which is set in mandrel, the end Lid is mounted on the end face of clamp body by screw, which is provided with through-hole, and sealing ring is equipped on through-hole side wall, institute Through-hole of the mandrel tail end on end cap is stated to be fixed in clamp body by flange.
Preferably, the cone of the clamp body is No. four cones of Morse.
The advantageous effects of the utility model are:This cuts the fixture of processing, letter reasonable in design for superfine shaft It is single, the probability that superfine shaft cuts workpiece deformation in processing is reduced, processing quality and processing efficiency are improved.
Detailed description of the invention
Fig. 1 is a kind of clamp structure schematic diagram that processing is cut for superfine shaft.
Wherein:1 is chuck, and 2 be end cap, and 3 be mandrel, and 4 be sealing ring, and 5 be bearing, and 6 be spacer sleeve, and 7 be nut, and 8 are Clamp body, 9 be tail stock, and 10 be sleeve, and 11 be washer, and 12 be bolt.
Specific embodiment
In conjunction with attached drawing, now the utility model is described in further detail.
As shown in Figure 1, a kind of fixture that processing is cut for superfine shaft, including by chuck 1, end cap 2, mandrel 3, sealing ring 4, bearing 5, spacer sleeve 6, nut 7, clamp body 8, tail stock 9, sleeve 10, washer 11, bolt 12 form, and the chuck 1 is Three-jaw self-centering chuck, described 8 one end of clamp body are cylindrical body, which is cone, the 10 inner cavity shape of sleeve The conical section of shape and clamp body 8 cooperates, and the chuck 1 is linked into an integrated entity by flange and the end of mandrel 3, the lathe tail 9 inner cavities of seat are equipped with sleeve 10 by screw, in the conical section insertion sleeve 10 of the clamp body 8, and by bolt 12 and The conical section of clamp body 8 and sleeve 10 are fixed as one by washer 11, and there are two bearings 5 for the tail end installation of the mandrel 3, should Two bearings 5 pass through two nut checks 7, are equipped with spacer sleeve 6 between the two bearings 5, which is set in mandrel 3, institute It states end cap 2 to be mounted on by screw on the end face of clamp body 8, which is provided with through-hole, and is equipped on through-hole side wall close Seal 4, the through-hole that 3 tail end of mandrel passes through on end cap 2 are fixed in clamp body 8 by flange.
Preferably, the cone of the clamp body 8 is No. four cones of Morse.
In actual work, first chuck 1 and the installation of mandrel 3 are integrated, then end cap 2 is first inserted in mandrel 3, is installed successively Bearing 5, spacer sleeve 6 and nut 7 are locked, and are then inserted into clamp body 8 in sleeve 10 from front, by bolt 12 and washer 11 from rear Face is put into sleeve 10, and clamp body 8 is tightened in sleeve 10.
Preferred embodiments of the present invention above described embodiment only expresses, the description thereof is more specific and detailed, But it should not be understood as limiting the scope of the patent of the utility model.It should be pointed out that for the common of this field For technical staff, without departing from the inventive concept of the premise, several deformations can also be made, improves and substitutes, these are all Belong to the protection scope of the utility model.Therefore, the scope of protection shall be subject to the appended claims for the utility model patent.
