Abstract

The invention discloses a toothholder positioning tool for a cutting head. The toothholder positioning tool for the cutting head is used for providing positioning for the toothholder when the toothholder is connected on a cutting head body of the cutting head. The toothholder positioning tool comprises an installing platform, a curved plate and a positioning structure; the installing platform is used for placing and fixing the cutting head body; the curved plate is installed on the installing platform; and the positioning structure comprises a connection portion connected with the curved plate and a fixing portion used for fixing the toothholder, the connection portion is connected with a positioning portion installed on the curved plate to define a first axis line, an included angle between the fist axis line and the water level is the chamfer of the toothholder, the fixing portion rotates around the first axis line relative to the connection portion to adjust the rotation angle of the toothholder. Compared with the prior art, the toothholder positioning tool can adjust the rotation angle of the toothholder, so that angle positioning of the toothholder is more accurate; in addition, according to the toothholder positioning tool, the angel of the toothholder is positioned by directly adjusting the installing process corner of the toothholder, so that the cutting function angle of cutting teeth is positioned, and positioning is more accurate.

Description

technical field [0001] The invention relates to the field of engineering machinery, in particular to a tooth seat positioning tool for a cutting head. Background technique [0002] The cutting head of the roadheader includes cutting head body, gear seat, pick, material guide plate, water nozzle and other components. Among them, the tooth seat is arranged on the cutting head body in the form of a helix, and the positioning accuracy of the tooth seat directly affects the performance of the cutting head. [0003] Such as figure 1 As shown, the tooth seat positioning tool of the cutting head in the prior art includes a base 1', a bent plate 2' and a tooth seat frame 3'. The tooth seat frame 3' is connected with different positioning holes on the bent plate 2' to complete the positioning of the tooth seat. However, the angle positioning of the tooth seat by the tooth seat positioning tool is not clear, and the rock-entry attitude of the pick cannot be guaranteed. Contents of...
