Embodiment Construction

[0031] The specific embodiment of the present invention will be further described in conjunction with the accompanying drawings.

[0032] Such as figure 1 , figure 2As shown, the pick-to-rock cutting mechanism test platform includes a base on which a stone material moving guide rail and a tool holder moving guide rail are arranged. The stone material moving guide rail and the tool holder moving guide rail are perpendicular to each other and include two parallel tracks respectively. A stone table is set on the above-mentioned stone moving guide rail, the outside of the stone table is connected to the stone table driving motor through a stone table driving screw, and a stone clamping device is arranged on the stone table.

[0033] Such as Figure 4 As shown, the stone clamping device includes a fixture platform and a height adjustment part of the fixture platform. The fixture platform includes a grooved platform in the middle and shoulders on both sides. The shoulders are V-s...

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 performance detection tests of picks, and in particular relates to a test platform for the cutting mechanism of picks against rocks. Background technique [0002] The pick installed on the working mechanism contacts the rock through circular motion and forms extrusion. When the extrusion force exceeds the limit of the physical and mechanical properties of the rock, the rock will crack and form an interception mark. During 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 rockfall. These factors are an important basis for evaluating the effective cutting of picks. It is very difficult to determine these factors due to the particularity of field conditions and the complexity of the cutting process. At present, the test instruments for the cutting process of picks are relatively simple, unable to approac...
