Multi-type tap grinding machine

Abstract

The invention relates to a multi-type tap grinding machine capable of grinding different types of old taps. It includes a bed and a track on it, a connecting arm connected to the slide table, a handle connected to the connecting arm, a connecting body, and a grinding wheel motor, and is characterized in that a lever arm is connected to the connecting body. The utility model not only has the advantages of simple structure, reasonable setting, and can sharpen new and old taps in batches, but also the sharpened taps are automatically guided and aligned by grooves instantly, and the operation is also very convenient. The setting of the stop pin and the spring prevents the The lever arm is upturned, cutting too much or the tap is grinding; the floating center seat and the locking piece make the tap rotate and not easy to fall off, and the operation is safe; the shape of the grinding wheel used matches the "U" surface part of the tap and will not change Or damage the effective length and cutting edge angle of the original tap, and the depth and size of the processed hole will not change after the machine is used again.

Description

technical field [0001] The invention relates to a screw tap grinding machine, in particular to a multi-type screw tap grinding machine capable of grinding different types of old screw taps. Background technique [0002] In the past industrial production, after the taps are worn out, they can be used for a period of time after simple manual sharpening. However, for the mechanical processing industry that uses a large number of taps, the method of manual sharpening cannot solve the problems encountered in the large-scale use of taps. In response to this problem, at present, discarding or low-cost processing is commonly used in the machining industry, resulting in great waste. Even if some taps are ground at the head end of the tap, in fact, the taps after grinding Not many workpieces can be processed at all, and the difficulties encountered when using the old taps cannot be solved, and the total length of the taps has also changed accordingly.
