Abstract
The invention relates to a gear locating clamp which comprises a clamp body, a squeezing nut, a collet and a locating bolt. A containing groove is formed in the clamp body, the collet is arranged in the containing groove and connected with the clamp body through a spring, multiple pins are evenly distributed on the inner wall of the collet, the locating bolt is further connected to the center of the collet, the clamp body is sleeved with the squeezing nut, one end of the squeezing nut is in contact connection with the clamp body, and the other end of the squeezing nut makes contact with the collet. The gear locating clamp has the advantages of being convenient to operate, stable in machining quality, high in work efficiency and the like.
Description
Technical field
The present invention relates to mechanical frock technical field, particularly a kind of gear positioning clamp.
Background technology
General gear, all needs toothed section heat treatment after processing profile of tooth, to improve hardness and the wearability of tooth surface.But heat treatment backgear often will be out of shape, and the gear to degree of precision, as automobile transmission gear etc., must the fine finishining such as roll flute be carried out.Pinion mounting holes after distortion must revise distortion as the positioning datum of fine finishining profile of tooth, at this moment should be benchmark with profile of tooth, revise installing hole, and it is simple that this just requires to design a kind of structure, the gear fixture that working (machining) efficiency is high.
Summary of the invention
For the problems referred to above, the object of this invention is to provide a kind of easy to operate, crudy is stablized, the gear positioning clamp that work efficiency is high.
Realize technical scheme of the present invention as follows:
A kind of gear positioning clamp, comprise clamp body, jam-packed nut, collet and bolt, described clamp body is provided with storage tank, collet to be arranged in storage tank and to be connected with clamp body by spring, collet inwall is evenly equipped with multiple alignment pin, and collet center is also connected with bolt, and jam-packed nut sleeve is located on clamp body, jam-packed nut one end contacts with clamp body and connects, and the other end contacts with collet.
Described collet and clamp body touching position are for being obliquely installed, and collet and jam-packed nut touching position are for being obliquely installed, and advantage is that to be convenient to collet elastic and extrude up and down.
Described collet head is set to three lobe bodies.
Have employed above-mentioned scheme, clamp body is connected with lathe spindle ring flange by bolt, and the uniform position of alignment pin is relevant to the gear number of teeth; Collet moves axially along clamp body inwall under the effect of jam-packed nut, and while movement, collet can be subject to the extruding of clamp body,, thus realizing self-centering clamping, clamping screw can by gear axial grip, prevent it from being ejected by collet, also facilitate the processing of gear simultaneously, spring can time collet reset, thus take out gear, the present invention is not only easy to operate, crudy is stablized, and work efficiency is high, is also very suitable for the fine finishining of gear shaft holes after gear hobbing.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
In accompanying drawing, 1 is clamp body, and 2 is collet, and 3 is spring, and 4 is jam-packed nut, and 5 is alignment pin, and 6 is bolt.
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 gear positioning clamp, comprise clamp body 1, jam-packed nut 4, collet 2 and bolt 6, described clamp body 1 is provided with storage tank, collet 2 to be arranged in storage tank and to be connected with clamp body 1 by spring 3, collet 2 inwall is evenly equipped with multiple alignment pin 5, alignment pin 5 inner cone cone angle is usually slightly larger than profile of tooth cone angle, 42 ° can be adopted, such positioning precision and clamping effect are all good, collet 2 center is also connected with bolt 6, jam-packed nut 4 is set on clamp body 1, jam-packed nut 4 one end contacts with clamp body 1 and connects, the other end contacts with collet 2.
Described collet 2 and clamp body 1 touching position are for being obliquely installed, and collet 2 and jam-packed nut 4 touching position are for being obliquely installed, and advantage is that to be convenient to collet elastic and extrude up and down.
Described elastic clip 2 head portion is set to three lobe bodies.
In concrete operations, processed gear to be contacted with alignment pin inner cone with profile of tooth and locates, and be close to end face and prevent from moving axially, screw jam-packed nut and drive collet, then screwing bolt, alignment pin jam-packed gear just can be made to process.
