Main shaft transmission mechanism based on cylindrical grinding machine

Abstract

The invention relates to the technical field of transmission mechanisms of cylindrical grinding machines, and discloses a main shaft transmission mechanism based on a cylindrical grinding machine, which comprises a transmission connecting shaft fixedly connected with a main shaft of the cylindrical grinding machine, and a first through groove extending into an inner cavity of the transmission connecting shaft is formed in one end of the transmission connecting shaft; and a friction module is movably sleeved with the first through groove in the transmission connecting shaft, one end of the transmission connecting shaft is movably sleeved with a supporting shaft sleeve, the inner wall of the supporting shaft sleeve is fixedly sleeved with an expansion ring sleeve, and the inner diameter of the expansion ring sleeve is smaller than the outer diameter of the outer surface of one end of the transmission connecting shaft. According to the main shaft transmission mechanism based on the cylindrical grinding machine, due to the arrangement of the linkage mechanism and the structure on the linkage mechanism, when the cylindrical grinding machine needs to be stopped emergently due to unforeseen circumstances, a transmission connecting shaft and a supporting shaft sleeve can form fixed transmission connection under the action of an electric thermal expansion ring on the linkage mechanism; and the grinding wheel on the main shaft is forced to quickly stop rotating along with the main shaft of the cylindrical grinding machine.

Description

technical field [0001] The invention relates to the technical field of the transmission mechanism of the cylindrical grinder, in particular to a main shaft transmission mechanism based on the cylindrical grinder. Background technique [0002] As a grinding equipment for cylindrical or conical parts, the cylindrical grinder not only needs to drive the parts to rotate, but also needs to drive the grinding wheel to rotate in the opposite direction to the parts. In turn, high-precision grinding of the component is achieved. [0003] However, when the existing cylindrical grinder drives the grinding wheel on it to rotate at a high speed, the quality of the grinding wheel is large due to the material of the grinding wheel, especially in some cylindrical grinders for processing large cylindrical or conical parts, Because the size of the grinding wheel itself is relatively large, which leads to a larger mass, so that the moment when the spindle on the grinding wheel drives the grin...

Problems solved by technology

[0003] However, when the existing cylindrical grinder drives the grinding wheel on it to rotate at high speed, its own mass is relatively large due to the material of the grinding wheel, especially in some cylindrical grinders that process large cylindrical or conical parts. Because the size of the grinding wheel itself is relatively large, its mass is even greater, causing the moment when the main shaft on it drives the grinding wheel to rotate, the momentary torque caused by the inertia is relatively large, and then extremely It is easy to cause impact damage to the inside of the spindle;

[0004] And when the cylindrical grinding machine stops working, one end of the upper main shaft will stop rotating in a short time due to internal gear transmission, and the heavy grinding wheel at the other end of the main shaft will make it It is difficult to stop the rotation in a short time, which will also cause a large degree of torque impact on the spindle of the cylindrical grinding machine, and will also cause a certain degree of impact on the transmission gear inside the cylindrical grinding machine, which intensifies its Wear and tear during transmission use

[0005] Therefore, there is an urgent need for a spindle transmission mechanism based on a cylindrical grinding machine to solve the adverse effects on the upper transmission parts caused by the above-mentioned existing cylindrical grinding machine when the grinding wheel with a large mass is driven to rotate or stop.
