Problems solved by technology

In the actual processing process, due to the error of the machine tool, assembly or workpiece itself, it is inevitable that the overall force of the grinding head will change or the force will be uneven, and this will change the shape of the removal function, and finally make the polishing The effect becomes worse

Abstract

The invention discloses a photoprocessing grinding head stress state monitoring device, relates to the technical field of optical cold processing, and provides a photoprocessing grinding head stress state monitoring device which provides a necessary means for guaranteeing processing quality. The device comprises a display unit, a signal transfer system, three force sensors, a connector, a frame, a power source, three bellows, a grinding head base and a grinding head, wherein the grinding head is arranged under the grinding head base, each bellows is cemented with each force sensor, the three groups of bellows are arranged on the circumference of the grinding head base at 120 degrees, the force sensors are arranged under the frame, and the connector is arranged above the frame. The device disclosed by the invention can be used for monitoring the stress state of the grinding head on line in real time in the processing process, and at the same time data is sent out and displayed through a data transmission system, so that the data is observed by an operator or is used as the reference for grinding head posture adjustment, and the necessary means is provided for guaranteeing the processing quality.

Description

technical field [0001] The invention relates to the technical field of optical cold processing, in particular to a device for monitoring the force state of an optical processing grinding head. Background technique [0002] The idea of ​​computer-controlled aspheric processing technology (CCOS) was first proposed by the American ltek company in the early 1970s. According to the quantitative surface shape detection data, on the basis of the process control model, it uses a computer to control a small grinding head (the diameter is usually less than 1 / 4 of the workpiece diameter) to grind or polish the optical parts. By controlling the grinding head on the workpiece The dwell time on the surface and the relative pressure between the grinding head and the workpiece are used to control the amount of material removed. [0003] The most critical point of CCOS is to have a stable removal function, and the grinding head pressure and pressure distribution will affect the shape of the...
