Large vertical grinder

Abstract

The present invention belongs to the field of machining equipment, and is especially large vertical grinder. The large vertical grinder consists of a vertical work table, a driving and transmitting apparatus connected to the work table, a track pedestal opposite to the work table, transverse tracks on the track pedestal and a guide plate stage on the transverse tracks, longitudinal tracks on the guide plate stage and a longitudinal guide plate, a grinding tool and a polishing wheel on the longitudinal guide plate. The grinding tool and the polishing wheel may be controlled in the control desk to move transversely and longitudinally. The present invention can perform grinding and polishing in the same apparatus and has no peripheral drooping, less motion resistance and low power consumption.

Description

technical field [0001] The invention belongs to the field of machining devices, and mainly relates to a grinding machine in machining. Background technique [0002] With the development of science and technology, the precision requirements for production equipment and various testing equipment in various industries are getting higher and higher, and correspondingly, the dimensional accuracy and surface requirements for the components of these production equipment and testing equipment are also increasing. Many parts need to be ground and polished before assembly, and the relevant equipment used is a grinding machine and a polishing machine. [0003] The grinding machine suitable for planar parts is a surface grinder, that is, the worktable of the grinding machine is placed horizontally, and the workpiece is also placed horizontally. For shaft-type parts, the workpiece is arranged along the horizontal X direction. [0004] In the existing surface grinder, its workbench is pl...

AI Technical Summary

Problems solved by technology

This kind of large workbench placed horizontally, when it is working and running, its support point is only the rotating shaft at the bottom. It can also be said that the support point is only a point. For the periphery of the workbench, it is in a suspended state. Due to the effect of gravity, the surrounding area is slightly Drooping causes the unevenness of the workbench. When the diameter of the workbench is large, the arm of the surrounding sag is also long (the radius is long), resulting in an increase in the sag around the workbench and the flatness of the workbench, resulting in the flatness of the workpiece on it. It also increases, which directly affects the grinding effect of the workpiece

At the same time, when the workbench is relatively uneven, the resistance of the rotating operation is increased, which not only increases the energy consumption, but also reduces the work efficiency.

In addition, since the workbench is placed horizontally, it is difficult for the operator to observe the polishing status and quality evaluation of the central part of the workpiece for a large workbench and workpiece over 3 meters long, and it is difficult to judge whether to continue polishing
