Abstract

The invention relates to a machining fixture which comprises a base and an elastic chuck arranged on the base. The elastic chuck is fixedly connected with the base through a bolt. A threaded hole is formed in the bottom of the base. A clamping groove is formed in the outer surface of the head portion of the elastic chuck. A squeezing groove is formed in the center of the elastic chuck. The machining fixture has the advantages of being simple in structure, convenient to operate, high in practicability, high in machining accuracy and the like.

Description

A kind of clamping tool for machine work
Technical field
The present invention relates to field of mechanical technique, be specifically related to a kind of clamping tool for machine work.
Background technology
Fixture refers to and be used for fixing processing object in machine-building process, makes it to occupy correct position, to accept the device of constructing or detecting.On lathe during processing work, the dimensions reaching drawing for making the surface energy of workpiece and specify, geometry and with the technical requirements such as the relative-position error on other surfaces, workpiece must be installed (location) before processing, clip (clamping).
Fixture of the prior art is when clamping work piece, easy generation is tilted or shift phenomenon, reduce the precision of converted products, at processing some ring-shaped work pieces, particularly bearing, general fixture or hanger is utilized to use inconvenient, positioning precision is not high, affect Workpiece Machining Accuracy, be easy to the end face of axle sleeve 1 to be processed to weigh wounded, have impact on the quality of axle sleeve processing.
Summary of the invention
For the problems referred to above, the object of this invention is to provide a kind of structure simple, the clamping tool for machine work of ring-shaped work pieces crudy can be improved.
Realize technical scheme of the present invention as follows:
A kind of clamping tool for machine work, comprise base and be arranged on the collet on base, described collet is fixedly connected with base by bolt, and base bottom is provided with screwed hole, the plush copper outer surface of collet is provided with draw-in groove, and the center of collet is provided with a squeezing groove.
Described squeezing groove is radial slot or conical hole slot, and advantage facilitates mounting parts to be extruded by collet, and part is loaded in draw-in groove.
Described draw-in groove is a cannelure or is two, three, four unit grooves, and advantage is the quantity that can arrange draw-in groove according to the shape of squeezing groove, can block part firmly.
Have employed above-mentioned scheme, squeezing groove on collet provides enough spaces, only need by collet interior extruding mutually during use, ring-shaped work pieces just can be set in the draw-in groove on collet, the elasticity of collet isomorphism self can restPose, now, part would not landing chuck, the round diameter that part is formed after being set on draw-in groove is greater than the maximum gauge of collet, adding man-hour, machine can be good at processing parts and can not damage chuck itself, and this structure is simple, easy to operate, substantially increase the crudy of part.
Accompanying drawing explanation
Fig. 1 is sectional view of the present invention;
In figure, 1 is base, and 2 is collet, and 3 is bolt, and 4 is draw-in groove, and 5 is squeezing groove, and 6 is screwed hole.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention is further described.
As Fig. 1, a kind of clamping tool for machine work, the collet 2 comprising base 1 and be arranged on base 1, described collet 2 is fixedly connected with base 1 by bolt 3, screwed hole 6 is provided with bottom base 1, the head exterior surface of collet 2 is provided with draw-in groove 4, and the center of collet 2 is provided with a squeezing groove 5.
Described squeezing groove 5 is radial slot or conical hole slot, advantage facilitates mounting parts to be extruded by collet 2, part is made to load in draw-in groove 4, draw-in groove 4 is a cannelure or is two, three, four unit grooves, advantage is the quantity that can arrange draw-in groove 4 according to the shape of squeezing groove 5, can block part firmly.

Claims (3)
