Auxiliary positioning device for welding body and point of end mill

Abstract

An auxiliary positioning device for welding a body and a point of an end mill comprises an embedded positioning frame for the body and the point, a clamping component after the body and the point areembedded, and an assembly component bracket during welding, wherein the embedded positioning frame consists of an upper bedplate, a base plate for stabilizing the integral positioning frame, and an upright post between the upper bedplate and the base plate; and a positioning groove matched with a mill block, a ceramic screw rod at the bottom of the positioning groove and a nut through hole are arranged on the upper bedplate. The welding support is composed of a table plate, a table plate supporting column, a screw base fixed to the table plate, a position adjusting screw on the screw base anda locking nut on the position adjusting screw, and an axial threaded hole capable of being connected with a ceramic screw is formed in the lower end of the position adjusting screw. The auxiliary positioning device has the advantages that the body and the point are accurately and stably combined through the embedded positioning frame, the mill block is accurately fed into a welding heating position through a welding support and kept stable, manual assembly and handheld control during welding are replaced, the repairing precision of the mill block is guaranteed, and the working efficiency is improved.

Description

technical field [0001] The invention belongs to the field of machinery, and in particular relates to an auxiliary positioning device in end mill cutter repair. Background technique [0002] During the use of metal cutting tools, there will be progressive wear of the tip (blade). Usually, the blades are replaced with new ones when they are worn to a certain extent. Some blades are relatively expensive, and frequent replacement of blades will inevitably increase the manufacturing cost of mechanical equipment. In order to reduce tool consumption in cutting, the most direct and effective way is to repair and reuse scrapped tool blocks. For the end mill milling cutter block, the cubic boron nitride tip is inlaid, welded, and then processed on a special tool grinder for refurbishment, so that it has the function of a new tool. [0003] Previously, the assembly and welding of the knife body and the knife tip that make up the knife block were all manual operations. The combination...

Problems solved by technology

Due to the different degrees of accuracy of the operation and the possible vibration, the mutual position of the knife tip and the knife body cannot be kept consistent, and the position of the high-frequency induction coil cannot be kept consistent, resulting in different quality of the finished product, and some knife blocks cannot be restored to the original state.
