Description

Guide sleeve precision grinding mechanism Technical Field The utility model relates to the technical field of guide sleeve grinding, in particular to a guide sleeve precise grinding mechanism. Background The guide sleeve precise grinding mechanism is a special grinding device or process system for precisely processing guide sleeves (usually mechanical guide elements), and is mainly used for ensuring the dimensional accuracy, shape accuracy and surface finish of key parts such as inner and outer circles, end faces and the like of the guide sleeves. The existing guide sleeve precise grinding mechanism does not have a multidirectional moving structure of a grinding fluid spray head when in use, so that when the grinding fluid is sprayed, a large-area spraying mode is generally adopted for guaranteeing the lubricating effect, the grinding fluid is wasted seriously, and the spray range cannot be flexibly adjusted according to the size of the guide sleeve and the grinding area due to the fixed position of the spray head, so that the use amount of the grinding fluid is increased, the cooling unevenness of a processing area is possibly caused, the processing precision and the surface quality are influenced, and the waste liquid treatment cost and the pollution risk of the working environment are increased. Therefore, the guide sleeve precise grinding mechanism can be designed aiming at the problem that the conventional guide sleeve precise grinding mechanism does not have a multidirectional moving structure of a grinding fluid spray head when in use, so that a large-area spraying mode is generally adopted for ensuring the lubrication effect when the grinding fluid is sprayed, and the grinding fluid is seriously wasted. Disclosure of utility model In order to overcome the defect that the existing guide sleeve precise grinding mechanism does not have a multidirectional moving structure for a grinding fluid spray head when in use, so that a large-area spraying mode is generally adopted to ensure a lubricating effect when the grinding fluid is sprayed, and the grinding fluid is seriously wasted.
