Spilt grinding wheel dynamic balance adjusting device

Abstract

The invention relates to a spilt grinding wheel dynamic balance adjusting device. The spilt grinding wheel dynamic balance adjusting device comprises a dynamic balance adjusting rod and a seal cover which detachably seals a handle hole in a grinding wheel guard, wherein the dynamic balance adjusting rod is divided into a gear transmission part and a handle part in the rod direction; the gear transmission part and the handle part are mutually independent and are in fit connection through a dovetail at the end face of a connecting end of the gear transmission part and a dovetail groove of the end face of a connecting end of the handle part; a limiting ring and a spring are arranged on the handle part in a sleeving manner; when the dynamic balance adjusting rod operates, one end of the springis propped against a non-connecting end of the handle part, and the other end of the spring presses the limiting ring on the end face of the connecting end of the gear transmission part; the dovetailis not separated from the dovetail groove through the limiting ring; the gear transmission part stretches into the handle hole to be in fit connection with grinding wheel dynamic balance; and the handle part is positioned on the outer side of the handle hole. According to the spilt grinding wheel dynamic balance adjusting device, grinding wheel dynamic balance can be adjusted, a changing space ofa grinding wheel is increased, and a grinding liquid is prevented from leaking from the handle hole.

Description

technical field [0001] The invention belongs to the field of grinding machine equipment, and in particular relates to a split type grinding wheel dynamic balance adjustment device. Background technique [0002] The grinding wheel is a key part of the grinding machine. If the grinding wheel is in an unbalanced state during operation, the vibration will continue to be transmitted to the mechanical parts of the equipment, especially the main shaft and bearings, which may deteriorate the working conditions of these mechanical parts for a period of time. Until it is completely damaged, the performance of the grinding head due to the vibration of the main shaft and the bearing will be reduced, and the quality of the workpiece will not be guaranteed. Therefore, the quality of the workpiece depends on the degree of balance of the grinding wheel, so the grinding machine is generally equipped with a dynamic balance of the grinding wheel.

[0002] The grinding wheel is a key part of the grinding machine. If the grinding wheel is in an unbalanced state during operation, the vibration will continue to be transmitted to the mechanical parts of the equipment, especially the main shaft and bearings, which may deteriorate the working conditions of these mechanical parts for a period of time. Until it is completely damaged, the performance of the grinding head due to the vibration of the main shaft and the bearing will be reduced, and the quality of the workpiece will not be guaranteed. Therefore, the quality of the workpiece depends on the degree of balance of the grinding wheel, so the grinding machine is generally equipped with a dynamic balance of the grinding wheel. The adjusting lever adjusts the position of the dynamic balance of the grinding wheel

[0003] When replacing the grinding wheel during the grinding process of the grinding machine, due to the compact structure of the replacement platform, the effective distance between the grinding wheel and the main shaft is very small, and it is easy to be scratched or broken, resulting in the loss of the adjustment function of the dynamic balance, and the main shaft and bearing bush are often injured due to impact Locking, even the spindle is scrapped, and equipment failure restricts normal production

Although operators continue to improve the grinding wheel replacement method, the problem of too small effective space for grinding wheel replacement has not been solved, and the dynamic balance adjustment function has always been threatened. Not only the cost of expensive spare parts such as the spindle increases the process cost, but also the grinding quality is also reduced. not guaranteed at all

[0004] Since the grinding wheel dynamic balance adjustment rod is adjusted externally after passing through the grinding wheel protection cover, during the grinding process, the grinding fluid in the grinding wheel protection cover will leak grinding fluid to the outside of the protection cover through the handle hole on the grinding wheel cover. The grinding wheel abrasive grains and roll grinding debris in the liquid will accumulate on the grinding wheel replacement platform outside the grinding wheel protection cover, causing damage to the grinding environment, and part of the grinding fluid will also leak into the Z-axis reducer or Z-axis under the platform. In the guideway groove, the guideway oil is polluted, not only the guideway oil fails, but also the metal particles in the grinding fluid accelerate the wear of the Z-axis drive screw and other equipment, resulting in a serious out-of-tolerance Z-axis transmission accuracy, and the Z-axis guideway oil is completely emulsified. Grinding mud deposits in gear reducers, failure of bearings and gears, etc.
