Detecting device for space angles of tooth holder

Abstract

The invention provides a detecting device for space angles of a tooth holder of a drum of a coal mining machine. The detecting device mainly comprises a round shaft, a shaft sleeve, a U-shaped component, a bolt connector, a sleeve, a locking device, a gradienter and an infrared laser pen, wherein one end of the round shaft is provided with outer threads and is in threaded connection with the locking device; the other end of the round shaft is hollow; the shaft sleeve is arranged at the other end of the round shaft; one end of the U-shaped connecting component is U-shaped and is connected with the shaft sleeve and the shaft through the bolt connector; the other end of the U-shaped connecting component is cylindrical, is provided with outer threads and is in threaded connection with the locking device; the sleeve is arranged on the U-shaped connecting component; and the gradienter and the infrared laser pen are arranged on the sleeve. The round shaft rotates relative to the shaft sleeve, the U-shaped connecting component rotates relative to the round shaft and the shaft sleeve, the sleeve rotates relative to the U-shaped connecting component, and correspondingly, the number of degrees is indicated on a graduated disc. By the detecting device, the mounting angle of the tooth holder can be detected directly and accurately, so that deviation between an actual value and a theoretical value is reduced, the service lives of cutting teeth and the service life of the tooth holder are prolonged, and the work stability of the whole detecting device is improved.

Description

technical field [0001] The invention relates to a detection device, in particular to a detection device for the space angle of a tooth seat on a shearer spiral drum. Background technique [0002] The pick is the main cutting part of the shearer, and it is the tool for cutting the working medium. It is installed in the tooth seat, and the tooth seat is welded on the spiral drum of the shearer. The accuracy of the installation angle adjustment of the tooth seat has a great influence on the shearer The force condition and service life of the tooth have a great influence, therefore, the detection of the space angle of the tooth seat is of great significance. At present, there is no direct detection device for the detection of the installation angle of the gear seat on the spiral drum of the coal shearer, and it is only detected by indirect means. There is a certain error in this indirect detection method, which makes the actual installation angle of the tooth seat and the theore...
