Utility model content
In view of the problems of the existing technology, the goal of the invention of the utility model be to provide it is a kind of facilitate processing, ensure
It can stablize clamping when master gear is in processing, cut a kind of grinding core degree clamping for avoiding occurring workpiece bounce in chamfered edge rotary course
Tool.
To achieve these goals, the technical solution adopted in the utility model is：
A kind of grinding core degree frock clamp, it is characterised in that including：Mandrel, the mandrel are divided into linkage section, construction section, set
Section is connect, the construction section coordinates with gear hole to be processed, is provided with /V section on the linkage section, the /V section diameter is more than
The construction section diameter, the /V section end face are bonded with the gear face to be processed, the mandrel linkage section end face center of circle
Place is provided with center hole I, the center hole I and top cooperation under chamfering device, is provided with external thread section in the socket section, institute
It states external thread section and is provided with external screw thread, the mandrel socket section tail end end face circle centre position is provided with center hole II, the center hole
II with chamfering device on top cooperation.Washer, the washer are socketed in the mandrel socket section；Nut, the nut pass through
External thread section with being arranged on the mandrel socket section coordinates, and washer is pressed on the flange of the work gear to be added.It is top
Hole I and center hole II cooperate, and during grinding core degree mandrel can be avoided to beat, and by nut by that will pad
Circle is pressed on the flange of the work gear to be added, and master gear can be compressed by forming seal face, make master gear in chamfered edge
Stablize and clamp, improve the precision of workpiece.
Preferably, the socket section tail end diameter is less than external thread section diameter.Facilitate the socket section insertion nut bore
In.
Preferably, the mandrel linkage section is arranged to flat axis, and mandrel flat part will be turned using spanner by, which facilitating, carries out
Installation.
Preferably, the nut bottom has flange.The contact area of nut and the washer can be increased so that stress is more
Add uniformly.
The beneficial effects of the utility model are：
The utility model is cooperated by center hole I and center hole II, during grinding core degree mandrel can be avoided to send out
The situation of raw bounce avoids, there is a situation where beating, promoting machining accuracy.
By nut by the way that washer is pressed on the flange of the work gear to be added, benchmark can be compressed by forming seal face
Gear makes master gear stablize in chamfered edge and clamps, improves the precision of workpiece.
