Test platform for cutting mechanism of cutting tooth on rock

Abstract

The invention belongs to the technical field of a cutting tooth performance detection test, particularly relates to a test platform for a cutting mechanism of a cutting tooth on a rock, and solves the problems that the conventional test instrument for the process of cutting the rock by the cutting tooth cannot be close to real field working conditions, and the test conditions are instable and cannot meet the practical needs of cutting tooth theory analysis. The test platform comprises a base, wherein stone moving guide rails and knife rest moving guide rails are arranged on the base; a stone moving device is arranged on the stone moving guide rails; the stone moving device comprises a stone table; a stone table drive motor is connected to the outer side of the stone table through a stone table drive screw rod; a stone clamping device is arranged on the stone table; and a knife rest moving device and a cutting tooth drive mechanism are arranged on the knife rest moving guide rails. The test platform has the benefits as follows: a test system close to the real cutting process can be provided under stable test conditions; the function is complete; the test range is large; the control accuracy is high; and the test data are reliable.

Description

Technical field [0001] The invention belongs to the technical field of pick performance detection tests, and specifically relates to a test platform for the cutting mechanism of picks on rocks. Background technique [0002] The picks installed on the working mechanism come into contact with the rock by rotating in a circular motion and form extrusion. When the extrusion force exceeds the limit of the physical and mechanical properties of the rock, the rock will crack and form a cut. In the cutting process, there is an interaction force between the pick and the rock, accompanied by physical phenomena such as sound, light, heat, dust, and falling rocks. These factors are an important basis for evaluating the effective cutting of picks. Due to the particularity of the site conditions and the complexity of the cutting process, it is very difficult to determine these factors. At present, the test instruments for the process of cutting the rock by the pick are relatively simple, whic...
