Pick positioning tool

Abstract

The invention discloses a cutting tooth positioning tool, which comprises a rotary plate, a support frame, a horizontal positioning mechanism, a vertical positioning mechanism and a horizontal rotating mechanism. The horizontal positioning mechanism comprises a horizontal sliding rail and a sliding table, the horizontal sliding rail is mounted on the support frame, the sliding table is sleeved on the horizontal sliding rail, and a driving mechanism I used for driving the sliding table to slide on the horizontal sliding rail is disposed between the sliding table and the horizontal siding rail; the vertical positioning mechanism consists of a vertical guide rail, and a driving mechanism II is arranged between the vertical guide rail and the sliding table; the horizontal rotating mechanism comprises a rotating seat and a horizontal rotating rod which is in running fit with the rotating seat, and a mounting portion provided with a hinge cutting tooth workpiece is disposed at the end, which is far away from the rotating seat, of the horizontal rotating rod; and the rotary plate comprises a base and a tray, and a hand wheel is disposed on the base. The cutting tooth positioning tool is applicable to working mechanisms of a cutting head of a development machine, a rotary drum of a coal mining machine or a drill of an auger coal mining machine during cutting tooth welding.

Description

technical field [0001] The invention relates to a positioning tool, in particular to a pick positioning tool used for the cutting head of a roadheader, a shearer drum or an auger shearer bit when the pick is welded, and is especially suitable for tunneling Machine cutting head. Background technique [0002] The performance of the working mechanism of mining machinery directly affects the stability and working ability of the machine. The positioning accuracy of the pick directly affects the load fluctuation of the working mechanism of mining machinery, thus affecting the performance of the working mechanism of mining machinery. [0003] The Chinese patent with the patent number ZL201020550621.4 discloses a pick installation tool for the cutting head of the roadheader, including a base on which a bent plate is installed, a plurality of holes are distributed on the bent plate, and a bracket and a positioning plate are arranged at the end of the bent plate. A number of position...

Problems solved by technology

[0004] Although the cutter installation tool for the cutting head of the roadheader can meet the requirements for installation and positioning of the cutter to a certain extent, its application range is small, and a cutter installation tool for the cutting head of the roadheader can only be applied to a specific size and model The cutting head of the roadheader can only be positioned at some specific angle positions, the positioning flexibility is poor, and it cannot meet the use requirements
