Abstract
The utility model relates to a clamping structure of a broaching tool of a vertical internal broaching machine. The clamping structure comprises an auxiliary chuck head body and a sliding sleeve, wherein the sliding sleeve is sleeved on the outer side of the auxiliary chuck head body, a plurality of steel ball holes are arranged on the same radial section between the wall of the auxiliary chuck head body and the sliding sleeve, steel balls are arranged in the steel ball holes, a check ring installation groove is arranged on the outer wall of the auxiliary chuck head body on the lower side of the steel ball holes, a check ring is arranged in the check ring installation groove, the upper end of the inner wall of the sliding sleeve is connected with the outer wall of the auxiliary chuck head body in matching mode, and the lower end of the inner wall of the sliding sleeve is provided with a check ring moving cavity. The clamping structure has the advantages of being compact and reasonable in structure and convenient and reliable to use, and effectively solves the problems of the clamp block type auxiliary chuck head body structure of being high in material cost, large in processing difficulty, long in assembling time, large in integral weight and the like.
Description
Technical field
The utility model relates to a kind of vertical internal broaching machine, is specifically related to a kind of vertical internal broaching machine broaching tool clamp structure.
Background technology
At present, the auxiliary collet body of vertical internal broaching machine mainly is to clamp with fixture block, has the material cost height, difficulty of processing is large, installation time is long and overall weight heavily waits shortcoming.
Summary of the invention
The purpose of this utility model is exactly the deficiency in the background technology, and a kind of vertical internal broaching machine broaching tool clamp structure is provided.
For achieving the above object, the utility model adopts following technical scheme: a kind of vertical internal broaching machine broaching tool clamp structure, comprise auxiliary collet body and sliding sleeve, sliding sleeve is sheathed on the auxiliary collet body outside, radially same section is provided with some steel balls hole on the wall of auxiliary collet body and between the sliding sleeve, steel ball is provided with steel ball in the hole, the outer wall of the auxiliary collet body of steel ball hole downside is provided with the back-up ring mounting groove, be provided with back-up ring in the back-up ring mounting groove, described sliding sleeve inwall upper end is connected with auxiliary collet body outer wall coupling, its inwall lower end is provided with the movable chamber of back-up ring.
For a kind of optimization of the present utility model, top, the movable chamber of described back-up ring offers the slope mouth.
For a kind of optimization of the present utility model, the steel ball hole is to prevent that steel ball from taking off into the pocket pore structure in the auxiliary collet body inwall near auxiliary collet body inwall one end.
For a kind of optimization of the present utility model, the diameter of described steel ball is greater than the wall thickness of auxiliary collet body, be less than or equal to wall thickness and the chamber wall in the movable chamber of back-up ring and the outer wall gap sum of auxiliary collet body of auxiliary collet body, the chamber wall in the movable chamber of back-up ring and the outer wall gap of auxiliary collet body are less than the radius of steel ball.
The utility model is compared with background technology, has compact conformation, reasonable, easy to use and reliable, and the material cost that has effectively solved the auxiliary chuck body structure existence of blocking piece type is high, difficulty of processing is large, installation time is long and overall weight heavily waits shortcoming.
