Description

Technical Field

[0001] The present invention relates to the technical field of precision machining, and particularly relates to a precision machining workpiece detection device, belonging to the technical field of workpiece detection devices. Background Art

[0002] Precision machining is a process of changing the external dimensions or properties of a workpiece using machining machinery. According to the temperature state of the workpiece being processed, it is divided into cold machining and hot machining. Generally, machining is carried out at room temperature without causing chemical or phase changes in the workpiece, which is called cold machining. Generally, machining at a temperature higher or lower than room temperature, which will cause chemical or phase changes in the workpiece, is called hot machining. Cold machining can be divided into cutting machining and pressure machining according to the difference in machining methods. Common hot machining methods include heat treatment, forging, casting, and welding. Machining is a way of processing parts, which processes raw materials to make them meet the final required specifications and has relatively high precision and quality. Different types of crankshafts or camshafts are often machined during the production of spare parts for industrial products such as automobiles. The curved surfaces of the machined crankshafts or camshafts need to pass precision inspection before they can be used. Precision cutting machining is a process of removing an extremely thin layer of metal from the surface of a workpiece with a very high or extremely low cutting speed, a very small depth of cut, and a very small feed rate by relying on a machine tool with high precision and good rigidity and a finely ground tool. Obviously, this process can significantly improve the machining precision of parts. Since the residual area in the cutting process is small, and the adverse effects of cutting force, cutting heat, and vibration are excluded to the greatest extent, it can effectively remove the surface metamorphic layer left by the previous process. After machining, the surface basically does not have residual tensile stress, and the surface roughness is also greatly reduced, greatly improving the machining surface quality.

[0003] After retrieval, in order to solve the problem of detecting the surface roughness of a workpiece after grinding using machine vision, taking images in real time to ensure machining precision, and aiming at the problem of grinding conical parts, the patent with the Chinese patent application number CN115648019A discloses a precision machining device based on machine vision detection. The invention discloses a precision machining device based on machine vision detection, which relates to the technical field of machining, including a machine frame, on which a lifting frame is slidably arranged, and a clamping component for clamping the workpiece is arranged at the top of the machine frame; a grinding and machining component is rotatably arranged on the lifting frame for grinding and machining the workpiece. The grinding and machining component includes a turntable rotatably installed on the lifting frame, an air box for blowing away waste chips is arranged on the turntable, and two groups of grinding components are also arranged on the turntable; an image acquisition head is arranged on the grinding component for acquiring images of the grinding area to detect the surface roughness of the workpiece; the present invention uses machine vision to detect the surface roughness of the workpiece after grinding, takes images in real time to ensure machining precision, and aims at grinding conical parts.

[0004] After the existing precision parts are processed, it is necessary to detect the size of the workpiece. In the precision machining manufacturing industry, it is crucial to ensure the accuracy of the processed parts' size. However, most of the existing measuring tools are manual measurements, with low measuring efficiency and prone to errors, thus reducing the accuracy during the measurement process. At the same time, the existing measuring devices are generally automated measuring stations such as pneumatic gauges. For workpieces of different sizes, it is not convenient to adjust, and it is rather inconvenient to limit the workpiece during the process, affecting the detection efficiency;
