Processing equipment of 1-shaped rock drilling drill bit milling alloy grooves

Abstract

The invention relates to processing equipment of 1-shaped rock drilling drill bit milling alloy grooves. The processing equipment comprises a machine seat, wherein one end on the machine seat is provided with a rotary milling cutter, and the other end on the machine seat is provided with a workpiece clamp. The processing equipment is characterized in that the workpiece clamp comprises a bearing seat arranged on the machine seat, a swinging shaft is arranged in the bearing seat, a clamp is arranged on the swinging shaft, a drill bit fixing hole is arranged in the clamp and is matched with a drill bit, the swinging shaft is pulled by an oil cylinder though a crank arm, the swinging shaft and the clamp do circular arc swinging after the oil cylinder does reciprocating movement, and the oil cylinder is arranged on the machine seat.

Description

technical field [0001] The invention relates to a rock drilling bit, in particular to processing equipment for milling an alloy groove with a straight rock drilling bit, which belongs to mining tools. Background technique [0002] During the construction of mining and tunnel excavation, various rock drilling bits are needed, and the most widely used is the inline drill bit, which is made with a "one" groove on the top of the drill bit. The cemented carbide block is welded in the groove. The center of the inline drill bit protrudes into contact with the rock, and the rock drilling speed is fast, so the alloy groove is arc-shaped. It is difficult to process the arc-shaped alloy groove for the inline rock drill bit. All kinds of existing milling machines cannot be processed, only through modification, a large disc is made, and radial workpiece fixing holes are formed around the big disc, and the drill bit blanks are installed in the fixing holes one by one, with the head expose...

Problems solved by technology

[0002] During the construction of mining and tunnel excavation, various rock drilling bits are needed, and the most widely used is the inline drill bit, which is made with a "one" groove on the top of the drill bit. The cemented carbide block is welded in the groove. The center of the inline drill bit protrudes into contact with the rock, and the rock drilling speed is fast, so the alloy groove is arc-shaped. It is difficult to process the arc-shaped alloy groove for the inline rock drill bit. All kinds of existing milling machines cannot be processed, only through modification, a large disc is made, and radial workpiece fixing holes are formed around the big disc, and the drill bit blanks are installed in the fixing holes one by one, with the head exposed, and the big round After the disk rotates, the drill bit blank moves with the circumference, contacts with the milling cutter, and mills out the alloy groove. The disadvantages of this processing equipment are: first, the diameter of the large disk is about 300 mm, the volume is very heavy, and the equipment investment is large; Every time the material is loaded and unloaded, it is necessary to stop the machine, unload the processed drill bits one by one, and install the drill bit blanks to be processed one by one. The work efficiency is low, and the daily output is 800-1000 pieces; the third is that the products are qualified. The rate is low, if there is a problem with one workpiece, it will affect the processing quality of other workpieces
