Milling device for rock drilling bit alloy groove for rock and soil exploration

Abstract

The invention relates to the technical field of rock drilling bits, and particularly relates to a milling device for a rock drilling bit alloy groove for rock and soil exploration. The device comprises a clamping mechanism, a rocker arm mechanism, traction mechanisms, a reciprocating driving mechanism, a milling machine and a controller, wherein the rocker arm mechanism is fixedly mounted on the reciprocating driving mechanism; the clamping mechanism is fixedly mounted on the rocker arm mechanism; every two symmetrical ends of a pair of traction mechanisms are fixedly connected with each of the bottom end of the rocker arm mechanism and a working part of the reciprocating driving mechanism correspondingly; the milling machine is arranged on one side of the clamping mechanism, and the axisof the working part and the axis of the reciprocating driving mechanism are collinear; and the reciprocating driving mechanism, the milling machine and the controller are in communication connection.The device is low in cost, motor driving is adopted, the service life is long, the swing amplitude can be conveniently adjusted, and the application range is wide.

Description

technical field [0001] The invention relates to the technical field of rock drilling bits, in particular to a rock drilling bit alloy groove milling equipment for rock and soil exploration. 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 exposed, and the ...

[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

[0003] Chinese patent CN201220228184.3 discloses a processing equipment for milling alloy grooves with an inline rock drill bit, including a machine base, a rotating milling cutter is arranged at one end of the machine base, and a workpiece fixture is arranged at the other end of the machine base, which is characterized in that The workpiece fixture includes a bearing seat installed on the machine base, a swing shaft is installed in the bearing seat, a fixture is installed on the swing shaft, a drill bit fixing hole is formed in the fixture, the fixing hole matches the drill bit, and the swing shaft is pulled by the oil cylinder through the crank arm After the oil cylinder reciprocates, the swing shaft and the fixture will swing in a circular arc. The oil cylinder is installed on the machine base, but the life of the oil cylinder is limited. It will be scrapped after about 20,000 reciprocating swings, and it is not easy to adjust the swing range. The scope of application is narrow. , it is necessary to provide a device with a longer service life and a wide range of applications
