Lever type pressurization mechanism of grinder

Abstract

The invention discloses a lever type pressurization mechanism of a grinder. The lever type pressurization mechanism of the grinder comprises a cylinder, bearing pedestals, an upper main shaft and a speed reduction motor; the middle portion of a lever is connected and fixed to a rocker arm supporting point; one end of the lever is connected to a support cylinder; the cylinder is connected with the lever through a connection sleeve; the other end of the lever is connected with an extension unit through a connection rod; the extension unit is fixed to a guide rail through bolts and provided with the upper bearing pedestal, and the upper main shaft is installed in the bearing pedestal and is engaged with an output shaft on the speed reduction motor; the other end of the upper main shaft is connected with an upper rotating disk through a coupler; and the upper rotating disk is fixed through the lower bearing pedestal. According to the technical scheme, the total height is reduced, transportation is convenient, the appearance structure is attractive, adjustment is convenient, accumulated errors are small, the precision required by a machine tool is easy to keep and is kept for a long time, the distance between the stand column center line of the mechanism and the main shaft center line on the upper disk is reduced, height is reduced, and therefore the weight is reduced, and materials are saved.

Description

technical field [0001] The invention relates to a lever type pressurizing mechanism of a grinding machine, which is especially suitable for use on a double-end surface grinding machine. Background technique [0002] At present, the pressure method of the upper plate of the domestic double-end grinding machine is mainly linear pneumatic pressure, which is connected in series by the cylinder, the connecting sleeve, the thrust bearing, the bearing seat, the upper spindle, the cylinder liner and the geared motor, etc. to form a long mechanism. Yes, it is easy to fail to guarantee the concentricity of the upper and lower axes due to accumulated errors, thus affecting the normal processing status of the machine tool. [0003] How to ensure the stability of the machine tool and the precision of the processed parts is the goal of continuous improvement and innovation of our technicians. Contents of the invention [0004] The task of the present invention is to propose a lever-typ...
