Embodiment Construction

[0032] The core purpose of the present invention is to overcome the defects of the existing MB1312 machine tool that the processed workpiece 8 is in a cantilever state during the processing of the processed workpiece 8 (such as milling cutter processing), and the processing accuracy of the processed workpiece 8 is not high.

[0033] The core technology of the present invention to achieve this core purpose is to install a supporting device 9 for the workpiece 8 on the basis of the existing MB1312 machine tool, and by installing the supporting device 9, the workpiece 8 will not It is in the cantilever beam state, so as to ensure that the blade and handle of the workpiece 8 to be processed have a high coaxiality during the processing process, and the processing accuracy is improved.

[0034] Below in conjunction with accompanying drawing, core technical scheme of the present invention is described, see figure 2 , figure 2 is a view of an embodiment of the present invention. T...

Abstract

The invention relates to an improved cylindrical grinding machine. The cylindrical grinding machine comprises a machine body and a working sliding table being placed on the machine body and being capable of horizontally sliding relative to the machine body, wherein a clamping device of a machined workpiece is fixed at one end of the working sliding table; a grinding device for cutting and grinding the machined workpiece is arranged at the other end of the working sliding table; between the clamping device and the grinding device, a supporting device of the machined workpiece is arranged at a position having a preset distance from the grinding; the supporting device is fixed on the horizontal sliding table; and by using the supporting device, an edge part of the machined workpiece jumps within a reasonable range relative to a handle part in the machining process so that the edge part and the handle part of the workpiece are always kept with good coaxiality to improve the machining accuracy of the workpiece.

Description

technical field [0001] The invention belongs to the field of mechanical processing, and in particular relates to an improved cylindrical grinder. Background technique [0002] Plunge grinding is an important machining method, including centerless grinding and cylindrical grinding. According to the different machine tools used, the workpiece can be finely ground, semi-finely ground and coarsely ground. The representative machine tool of centerless grinding machine is 150-SL20 cutting and grinding machine tool of AGTHON company, which is a kind of precision grinding machine tool. When processing parts, the handle of the workpiece is used as the reference, and the pressure wheel of the concentric grinding attachment presses the handle of the workpiece tightly against the guide wheel and the supporting piece, and the workpiece is driven to rotate through the guide wheel. This processing method has a huge and complicated mechanism and is very There are too many standard parts, ...
