Summary of the invention

The purpose of this utility model provides a kind of time weak point of cut tap, the angular standard of grinding, tap grinder easy to use.

The purpose of this utility model is achieved in that

The tap grinder, include housing and motor, on motor shaft, be connected with abradant emery wheel, housing outside the emery wheel front end face is provided with the first tap anchor clamps locating rack that the cut tap end face is used, housing outside the emery wheel side is provided with the second tap anchor clamps locating rack of cut tap curved guiding surface, the 3rd tap anchor clamps locating rack in cut tap cutting face is installed above the second tap anchor clamps locating rack, the rotational angle of the second tap anchor clamps locating rack and the 3rd tap anchor clamps locating rack mounted thereto is by adjusting by mechanical transmission mechanism and rotary handle, at the first tap anchor clamps locating rack, the second tap anchor clamps locating rack, the top of the 3rd tap anchor clamps locating rack is provided with the installing hole that can insert the tap anchor clamps, but is provided with the flexible chuck that clamping screw is attacked in a side of described tap anchor clamps.

The both ends in the cross section of above-mentioned emery wheel are the lug boss of two " m " shapes, form the abradant surface of tap front end face, tap curved guiding surface in the front of emery wheel, and the lug boss of making on the external cylindrical surface of emery wheel forms the tap cutting face.

Be provided with the bolt of the second tap anchor clamps locating rack in the bottom of the second above-mentioned tap anchor clamps locating rack.

Be provided with the scale and the scale value of second tap anchor clamps locating rack anglec of rotation indication usefulness in the lower external face of the second above-mentioned tap anchor clamps locating rack.

The outstanding compared to existing technology advantage of the utility model is:

1, the utility model makes the grinding technique of tap oversimplify, and utilizes this equipment, no matter have or not the grinding experience of tap, all can grasp the grinding technique of tap soon;

2, use milling time weak point, the abrasion site standard of the utility model cut tap unified, be convenient to utilize the tap of grinding to carry out tapping;

3, manufacturing simple in structure, easy of the present utility model, easy to use, easy to utilize.
