A constant force grinding system integrating detection and grinding functions

Abstract

The invention discloses a constant-force grinding system integrating detection with grinding. The constant-force grinding system is characterized by comprising a working table, as well as an on-line detecting system, a constant-force grinding system and a controller mounted on the working table; the controller controls operation of the constant-force grinding system according to the information fed back by the on-line detecting system; the constant-force grinding system comprises a servo motor, a synchronous transmission mechanism and a working table return device; the servo motor serves as a constant-torque servo motor; the constant-torque servo motor is converted into the constant feed force of the working table through transmission of the synchronous transmission mechanism; and the working table return device is used for realizing returning of horizontal operation of the working table. Aiming at a machine tool transmission chain deformation phenomenon caused by unstable grinding feed force during ground finish and the constant-displacement forceful feeding mode adopted in numerically controlled grinder design, the design concept of constant-force grinding is adopted, and the grinding feed force is set into a constant quantity from an unstable variable, so that deformation of a machine tool transmission chain is in a stale state.

Description

technical field [0001] The invention relates to the technical field of hard alloy disc grinding, in particular to a constant force grinding system integrating detection and grinding functions. Background technique [0002] All machines are composed of three major parts: prime mover, transmission and actuator. The overall layout of the machine includes the distribution of motion and power, the design of the transmission system, and the working conditions of the actuator. The prime mover can be composed of an electric motor, a hydraulic mechanism, a wind mechanism, etc. It provides power and motion for the entire mechanical device and is the heart of the mechanical device; the function of the transmission mechanism is to transmit motion and power. The motion is transmitted to the actuator, and the motion nature, direction, size and speed of the prime mover can be changed through the transmission mechanism; the actuator is a device that executes the predetermined motion and po...

Problems solved by technology

[0004] In general, the feeding system of CNC grinding machine is to feed with constant displacement according to the speed given in the program. During the feeding process, the grinding force changes due to the change of the back cutting amount, so that the deformation of the machine tool drive chain is at unstable state

When grinding cemented carbide discs, diamond grinding wheels are used to grind cemented carbide materials. The constant displacement feed of the machine tool feed mechanism causes a sharp increase in grinding force, which generates a large amount of grinding heat, which can easily cause the cemented carbide materials to grinding surface burn

Therefore, the grinding of the end face of the cemented carbide disc can only be processed by manual feeding with an ordinary grinder. The disadvantages of this processing method are: high labor intensity, low production efficiency, small and unstable feed force
