For this purpose, in view of the above-mentioned problems, it is proposed that a kind of solving this for the fixture with taper hole workpiece of numerically-controlled machine tool One problem.
Utility model content
It is above-mentioned to solve the purpose of this utility model is to provide a kind of fixture with taper hole workpiece for numerically-controlled machine tool The current problem for the clamping with taper hole workpiece and inloading part inconvenience proposed in background technology.
To achieve the above object, the utility model provides the following technical solutions:A kind of band taper hole work for numerically-controlled machine tool The fixture of part, including pedestal, endoporus, cylinder push-rod, nut, bulge loop, spring, pushing block, key, clamping body, workpiece, external thread part, The right end of the self-locking conical surface and keyway, the clamping body is equipped with the self-locking conical surface, and the self-locking conical surface matches company with the taper hole of workpiece It connects, the endoporus of accommodating cylinder push-rod is equipped on the pedestal and clamping body, spring, and gas are arranged on the cylinder push-rod The right end of cylinder push rod is equipped with pushing block.
Preferably, be equipped with keyway on the pedestal and clamping body, the key be inserted into keyway to pedestal and clamping body into Row limit.
Preferably, the left end of the clamping body is equipped with external thread part, and the clamping body is sheathed on pedestal, and external screw thread Portion is connected with nut by screw thread.
Preferably, the pedestal is equipped with bulge loop, and the bulge loop is connected with nut by screw thread.
Compared with prior art, the utility model has the advantages that:
1. the utility model is equipped with the clamping body being detachably connected between pedestal, when processing different workpieces, only Clamping body need to be replaced, and clamping body is convenient to disassembly, practicability is good.
2. the utility model is positioned and fixed to pedestal and clamping body using key, torque is transmitted using key, can be kept away The problem of clamping body caused by exempting from process is rotated, fallen off, ensures the stability of process.
Description of the drawings
FIG. 1 is a schematic structural view of the utility model;
Fig. 2 is the utility model clamping body structural schematic diagram.
In figure:1, pedestal, 2, endoporus, 3, cylinder push-rod, 4, nut, 5, bulge loop, 6, spring, 7, pushing block, 8, key, 9, clamping Body, 10, workpiece, 11, external thread part, 12, the self-locking conical surface, 13, keyway.
Specific implementation mode
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work The every other embodiment obtained, shall fall within the protection scope of the present invention.
- 2 are please referred to Fig.1, the utility model provides a kind of technical solution:It is a kind of for numerically-controlled machine tool with taper hole workpiece Fixture, including it is pedestal 1, endoporus 2, cylinder push-rod 3, nut 4, bulge loop 5, spring 6, pushing block 7, key 8, clamping body 9, workpiece 10, outer The right end of threaded portion 11, the self-locking conical surface 12 and keyway 13, clamping body 9 is equipped with the self-locking conical surface 12, the self-locking conical surface 12 and workpiece 10 Taper hole is in mating connection, and the endoporus 2 of accommodating cylinder push-rod 3 is equipped on pedestal 1 and clamping body 9, is arranged on cylinder push-rod 3 There is spring 6, and the right end of cylinder push-rod 3 is equipped with pushing block 7.
In above-described embodiment, specifically, being equipped with keyway 13 on pedestal 1 and clamping body 9, key 8 is inserted into keyway 13 bottom of to Seat 1 and clamping body 9 are limited, and the rotational freedom of clamping body 9 are determined by key 8, and transmit torque using key 8, avoided The problem of clamping body is rotated, is fallen off in process.
In above-described embodiment, specifically, the left end of clamping body 9 is equipped with external thread part 11, clamping body 9 is sheathed on pedestal 1, And external thread part 11 is connected with nut 4 by screw thread, and the steady of external thread part 11 and the connection reinforcement clamping body 9 of nut 4 is utilized It is qualitative.
