Separated type multiple cutting-edge grinding cutter unit

Abstract

The invention provides a separated type multiple cutting-edge grinding cutter unit. The separated type multiple cutting-edge grinding cutter unit comprises an upper cutting head, a lower cutting head and cutter blades, wherein the cutter blades are a first cutter blade and a second cutter blade which are matched with each other and are clamped between the upper cutting head and the lower cutting head; and the upper cutting head and the lower cutting head are tightly connected by a bolt. The separated type multiple cutting-edge grinding cutter unit has the beneficial effects that the double edges of the two cutter blades are matched together to ensure that the cutter is in a multiple cutting-edge combination state; the cutter blades are located axially and radially through the separated type of the cutting heads which are the upper cutting head and the lower cutting head so as to ensure the accuracy of cutting edge location; the upper cutting head and the lower cutting head are connected through installing hole locations of the upper cutting head and the lower cutting head; the improvement of grinding speed of an electrode cap can be realized conveniently, simply and reliably by the cutter; and the wearing of the grinding cutter blades and the consumption of the cutting heads are reduced.

Description

Technical field [0001] The present invention relates to a technical solution applied to automated resistance spot welding of automobile bodies. It is the core technology of using an automatic grinder equipped with a grinding knife to grind the electrode caps of resistance spot welding guns and welding clamps, thereby realizing full automation of automobile body welding. The invention belongs to the field of automated automobile production and manufacturing, and specifically relates to a split multi-blade grinding tool unit. Background technique [0002] In the current manufacturing of automobile bodies, a large number of welding processes are required. Resistance spot welding is widely used in vehicle body manufacturing welding processes due to its rapidity, high reliability, strong adaptability and low application cost. A modern automobile body contains more than 3,000 resistance spot welding points. Due to the extensive application of resistance spot welding technology, a...

AI Technical Summary

Problems solved by technology

At present, when it is necessary to ensure the flatness of the electrode cap, the maximum speed is determined to be about 3000 rpm, so that in the case of a single blade, the cutting time will be longer

In addition, during the cutting process of the electrode cap, the cutting edge of the grinding tool will be worn. The feed rate and cutting amount of the electrode cap each time are basically confirmed values. The current single-edge tool wears faster

Moreover, the blade and the tool seat are integrated, and after the blade wears out, the entire tool needs to be replaced, which is costly
