In-situ finishing machine of outline grinding abrasion wheel

Abstract

The invention discloses an in-situ finishing machine of an outline grinding abrasion wheel. The in-situ finishing machine comprises a motor, a transmission device, a finishing shaft and a finishing rolling wheel. One end of the transmission device is connected with the motor, and the other end of the transmission device is connected with the shaft. The finishing rolling wheel is arranged on the finishing shaft. The transmission device is used for transmitting motor energy to the finishing shaft to drive the finishing shaft to rotate, and then the finishing rolling wheel is driven to rotate. The rolling wheel axis of the finishing rolling wheel is perpendicular to the abrasion wheel axis of the to-be-ground abrasion wheel. The finishing rolling wheel is used for carrying out in-situ finishing on the to-be-ground abrasion wheel. The in-situ finishing machine of the outline grinding abrasion wheel can be used in situ, uniform wear of the finishing rolling wheel can be kept, and thereforethe finishing precision of the abrasion wheel is improved.

Description

technical field [0001] The invention relates to the technical field of contour grinding wheel processing, in particular to an in-situ dresser for contour grinding wheels. Background technique [0002] With the rapid development of the national defense industry, mold manufacturing and tool manufacturing industry, the demand for various complex and precise tools, molds and other contour curve parts is increasing. Such parts with complex contour curves not only have high hardness , the requirements for its manufacturing precision are getting higher and higher. The final processing is done by a CNC contour curve grinder using a thin double-slope arc grinding wheel to achieve contour point grinding, and the material is removed by the arc of the grinding wheel tip. The sharp arc is worn during the machining process, and its arc shape accuracy deviates from the normal value with the increase of processing time. The contour of the grinding wheel must be trimmed to ensure the grindin...

Problems solved by technology

[0003] The existing contour grinding grinding wheel dressing mainly adopts diamond roller to trim the contour of the grinding wheel. During dressing, the diamond roller does not rotate, and the grinding wheel is trimmed through the relative movement between the grinding wheel and the cylindrical dressing roller to obtain the required contour size and shape accuracy of the grinding wheel. The dressing roller after the first use will reduce its own shape accuracy due to uneven wear, making the dressing accuracy of the grinding wheel uncontrollable and reducing the dressing accuracy of the grinding wheel profile

[0004] In order to improve the dressing performance of the grinding wheel, the Chinese invention patent application number: 201110157028.2 has announced a grinding wheel dresser, including the grinding wheel spindle and the driving spindle motor, which is mainly used for dressing the grinding wheel of the vertical grinding machine. It introduces single point dressing and double circle There are two types of camber wheel dressing, the single-point method is mainly used for auxiliary dressing, but it cannot be used for online dressing of curved profile grinding wheels
