Constant-force grinding system integrating detection with grinding

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 parts: the prime mover, the transmission mechanism and the actuator. The overall layout of the machinery includes the distribution of motion and power, the design of the transmission system, and the working conditions of the actuator. The driving mechanism can be composed of electric motors, hydraulic mechanisms, wind mechanisms, etc. It provides power and movement for the entire mechanical device, and is the heart of the mechanical device; the function of the transmission mechanism is to transmit movement and power, and it combines the power of the driving mechanism with the original The motion is transmitted to the actuator, and the nature, direction, size and speed of the original motion mechanism can be changed through th...

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
