Embodiment Construction

[0013] The grinding radial force monitoring method of grinding machine and the constant force feeding realization method described in the present invention detect the feed force of the workpiece or the grinding wheel in the feeding process of the grinding machine, and control the driving of the workpiece or the grinding wheel according to the value of the detected feed force. The drive mechanism of the grinding wheel to apply a constant amount of feed force to the workpiece or grinding wheel. The detection of the feed force is performed by setting a force measuring sensor on the driving mechanism. Said feed force is the radial feed force of the grinding wheel of the grinding machine.

[0014] The present invention detects the stress on the grinding wheel mandrel, the grinding wheel base, the workpiece mandrel, the workpiece base, etc. during the feeding process of the grinding machine. All grinders that provide feedback during grinding feed and judge the size of forward resis...

Abstract

The invention discloses a method for monitoring the radial grinding force of a grinder and realizing constant-force feeding, comprising the steps of: detecting the feeding force of a workpiece or a grinding wheel in the feeding process of the grinder; and controlling a driving mechanism which drives the workpiece or the grinding wheel according to the detected feeding force so as to apply constant feeding force on the workpiece or the grinding wheel. In the invention, through changing a method for applying the unknown radial force of the grinding wheel of the grinder into a method for applying the known radial force (controlling the force) or a method for detecting the radial force of the grinding wheel (detecting the force), the constant-pressure grinding of the grinder is realized and the purposes of achieving the grinding efficiency, ensuring the precision of the product and protecting the grinding wheel are achieved. By means of the invention, the problem that the machining effect after the automation and the numerical control of the grinder is bad is solved; and if the devices such as a workpiece online measuring instrument and the like are used, the effect in strict accordance with coarse-fine-finish grinding process requirements and fully closed-loop numerical control machining can be achieved.

Description

technical field [0001] The invention relates to a method for monitoring the radial force of the grinding wheel of a grinding machine and a method for realizing constant force feeding. Background technique [0002] At present, the grinding machines on the market include ordinary manual grinding machines, CNC grinding machines and grinding machines with online measurement control. None of these existing grinding machines can solve the problem of the coordination between the blunt edge of the grinding wheel and the feed control, and they all belong to forced feed. [0003] The strength of the grinding wheel itself and the stress generated during high-speed rotation are the two keys to the safety of the grinding wheel. [0004] The grinding wheel has been manufactured from three parts to ensure its strength: substrate, bonding layer and abrasive layer. Their strength is greater than the stress generated during high-speed rotation, the grinding wheel will not break, and the abra...
