A grinding machine with an encoder

Abstract

The invention belongs to production equipment of metallurgy industry, and particularly relates to a sharpening machine encoder installing method. The flexible connection between a rotating shaft and an encoder shaft is realized, the installation errors of a support frame are reduced, the practical rotating center lines of the rotating shaft and the encoder shaft are allowed to have a radial deviation value within 2mm, meanwhile, the jumping value within 2mm in the axial direction is allowed, the production requirements of sharpening machines in the prior art are completely met, and the fracture failure of an encoder installing device is eliminated.

Description

technical field [0001] The invention belongs to auxiliary facilities for metallurgical production, in particular to a grinding machine with an encoder. Background technique [0002] The grinding machine is used to remove the surface defects of the continuous casting slab and improve the surface quality of the continuous casting slab. The core component grinding head is installed in the hanger. The front part of the hanger is connected with the main frame through the oil cylinder. The relative position between the grinding head and the continuous casting slab can be changed, and the rear part is connected with the main frame through the bearing seat, and can rotate around the center of the rotating shaft; the encoder is a component used to detect the value of the rotation angle, including the encoder housing and the code There are two parts of the encoder shaft. The encoder shaft is installed on the encoder housing and can rotate around the center of the encoder shaft. The re...

Problems solved by technology

[0005] This installation method has the following problems: the detection shaft 6, the connecting sleeve 4, and the encoder shaft 2 are all rigidly connected, and the position of the internal thread structure of the rotating shaft 8 will deviate from the actual rotation centerline during processing, and the bearing 11 exists If there is a certain clearance, the bracket 3 will produce installation errors during the installation process, which will cause the position deviation of the encoder housing 1 installed on the bracket 3, resulting in a position deviation of the encoder shaft 2, so that the encoder shaft 2 and the detection shaft 6 The amount of non-concentricity randomly changes between them, and internal stress is generated in the rigid coupling body of the detection shaft 6, the connecting sleeve 4, and the encoder shaft 2. When the internal stress value is greater than the bonding force at the weakest point in the rigid coupling body , the installation device will break from here, equipment failure occurs, and it must be shut down for maintenance. Such failures occur on average every three days
