Double-hob experiment table cutter system

Abstract

The invention provides a double-hob experiment table cutter system and relates to an experiment cutter system. The cutter system can achieve bidirectional position adjustment and is characterized in that: the design of a hob rack can meet the requirement of mounting three types of hobs of 14 inches, 17 inches and 19 inches for experiment; the hobs are mainly arranged on flanges on both sides and a bottom supporting flange; two annular surfaces inside and outside a side face flange are connected with the hob rack to bear lateral impact load; the flanges are connected with a tool apron through bolts; the distance between the hob racks is adjusted by using a manual driving screw rod in an X direction and a Y direction which are vertical to each other, wherein the adjustment in the X direction is from -10 millimeters to 150 millimeters; the adjustment in the Y direction is from 300 millimeters to 500 millimeters; and the Y direction tool apron which bears main load is adjusted and locked through cooperation between the tool apron and saw-shaped threads on a cutter head pedestal. After the cutter system is applied in the hob experiment table, a measuring cell can be arranged to test hob stress and research rock breaking mechanism and cutter abrasion.

Description

technical field [0001] The invention relates to a test tool system, in particular to an adjustable double hob system for a hob test bench, which allows the use of hobs of different sizes, is convenient to adjust, has a large range, is safe and reliable, and is a large-scale heavy-duty test device part. It belongs to the design, manufacture and assembly technology of large test bench parts. Background technique [0002] Rock boring machines have been widely used in tunnel projects that need to pass through rock formations such as railways, hydropower, highways, subways, and municipalities. At present, domestic roadheaders have a low market share in the domestic market, and there is a large gap between domestic key components and foreign products, which is extremely inconsistent with my country's economic development. In particular, sensitive information such as national defense security, national strategic military projects, and land resources should not be participated in ...

AI Technical Summary

Problems solved by technology

Some people in China have designed the cutter in the arc-shaped T-slot, and changed the position of the cutter in the T-slot to break rocks. First, it is difficult to adjust the cutter. Secondly, the experiment with the same distance between the two hobs cannot be repeated many times. The table cannot roll other parts, resulting in the formation of an annular channel on the test piece; again, the highest rolling speed is not specified, and it is difficult to approach the actual working conditions
