Feeding and discharging method of fine grinding machine

Abstract

The invention belongs to the technical field of grinding machines, and discloses a fine grinding machine feeding and discharging method. The disclosed feeding and discharging method of the lapping grinding machine comprises the steps that magnetic adsorption devices used for grabbing workpieces are arranged on the feeding side and the discharging side of the lapping grinding machine correspondingly, and the workpieces are adsorbed and grabbed by the magnetic adsorption devices and placed on two grinding rollers; a spring propelling device arranged on the feeding side of the fine grinding machine acts; when the spring propelling device just starts to work, an elastic pusher of the spring propelling device is compressed; when the workpiece pushed by the spring pushing device is in contact with the previous group of workpieces, the elastic pusher is continuously forced to be compressed; after the spring propelling device continues to advance forwards to reach the stroke, the spring propelling device stops pushing, at the moment, the new workpiece is driven by the grinding roller to naturally advance forwards, and meanwhile, the elastic pusher gradually releases elastic force and continues to elastically advance the new workpiece forwards till the new workpiece is thoroughly separated from the magnetic adsorption mechanism. The working efficiency is improved, and time and labor are saved.

Description

technical field [0001] The invention belongs to the technical field of grinding machines, and in particular relates to a loading and unloading method on a fine grinding machine. Background technique [0002] At present, the loading and unloading of the fine grinding bed is mainly done manually. The specific steps are: the operator places multiple groups of workpieces to be ground between two grinding rollers, and the middle group of workpieces is pressed by the oil stone, and each group before entering the oil stone The workpiece is supported by the operator at the end by hand, and the rotation of the grinding roller drives the workpiece to grind the workpiece. With the rotation of the grinding roller, a group of workpieces pressed by the oilstone gradually break away from the oilstone, and a group of workpieces behind it gradually Enter between the whetstone and the two grinding rollers. At this time, the operator needs to use a hand-held rod similar to chopsticks to pick t...

[0002] At present, the loading and unloading of the fine grinding bed is mainly done manually. The specific steps are: the operator places multiple groups of workpieces to be ground between two grinding rollers, and the middle group of workpieces is pressed by the oil stone, and each group before entering the oil stone The workpiece is supported by the operator at the end by hand, and the rotation of the grinding roller drives the workpiece to grind the workpiece. With the rotation of the grinding roller, a group of workpieces pressed by the oilstone gradually break away from the oilstone, and a group of workpieces behind it gradually Enter between the whetstone and the two grinding rollers. At this time, the operator needs to use a hand-held rod similar to chopsticks to pick the front-end group of workpieces that have been ground to the whetstone and wait in line for regrinding. After the workpieces are ground to the required precision, stop the fine grinding machine, place the next batch of workpieces on the fine grinding machine, and then start the machine for grinding. Once the fine grinding machine is turned on, the operator will continue to stir the workpieces in a cycle, which is time-consuming and laborious. And the work efficiency is low; when processing workpieces with different diameters, it is necessary to adjust the distance between the two grinding rollers according to the different diameters of the processed workpieces. Since one of the two grinding rollers is a fixed roller, the adjustment of the distance When grinding, another grinding roller needs to be adjusted, so when grinding the workpiece, the center of the workpiece changes accordingly; in summary, in order to improve the work efficiency of loading and unloading, we urgently need a fine grinding bed loading and unloading machine that can replace manual work. method
