Surface grinder with lifting platform

Abstract

The invention discloses a surface grinder with a lifting platform, and belongs to the technical field of surface grinders. The surface grinder with the lifting platform comprises a lathe bed. A fixedseat is arranged at the top of the lathe bed, the lifting platform is arranged at the top of the fixed seat, fixed blocks are arranged on the outer sides of the bottom of the left and right sides of the fixed seat, and a rotating bevel gear is arranged at the bottom of the outer wall of a screw rod. The rotating bevel gear meshes with a driven bevel gear, lifting blocks are arranged on the inner sides of the bottom of the left and right sides of the lifting platform, the lifting blocks are screwed to a screw rod in a threaded mode, and a stand column is arranged at the rear end of the lathe bed. An upper and lower moving plate is arranged at the left end of the stand column. A front and rear moving plate is arranged at the left end of the upper and lower moving plate, and a grinding wheelframe is arranged at the left end of the front and rear moving plate. A grinding wheel is arranged at the bottom of the grinding wheel frame. The surface grinder with the lifting platform can adjust the lifting and lowering of a working platform slightly by manually rotating a rotating disc, and the requirement of accurate grinding is met.

Description

technical field [0001] The invention relates to the technical field of surface grinders, in particular to a surface grinder with a lifting platform. Background technique [0002] In the production of mechanical workpieces, in order to ensure the size and surface quality requirements of the workpieces, a grinding process is often arranged at the end. Most of the grinding processes use surface grinders. During the operation of surface grinders, the movement accuracy of the feed and movement structures is not high. It can only move roughly, and the grinding accuracy is not high. It is easy to collide with the workpiece or over-grind during grinding, resulting in the scrapping of the workpiece. It is necessary to fine-tune the grinding lifting movement to ensure the grinding quality of the workpiece. For this purpose, we propose a surface grinder with a lifting platform. Contents of the invention [0003] The object of the present invention is to provide a surface grinder wit...
