Description

A tool detector

technical field

The utility model relates to the technical field of tool production, processing and grinding, in particular to a tool detector.

Background technique

In recent years, with the rapid development of my country's economy, the demand for automobiles has continued to grow. The production process of the automobile industry involves a lot of mechanical processing, especially the use of cutting tools for metal cutting. The size, precision, and surface morphology of the workpiece processed by metal cutting are all related to the quality of the tool. The quality of the tool directly affects whether the required qualified products can be successfully processed, and affects the processing cycle and production efficiency.

In the modern automobile manufacturing industry, many companies pay attention to the manufacture of knives, but ignore the grinding of knives. Since the cost of cutting tools occupies a considerable proportion in the manufacturing cost of auto parts, and the reuse of cutting tools can reduce the cost of cutting tools, thereby reducing the production cost of enterprises.

In general, a knife can be sharpened at least 5 times. In the process of tool grinding, due to the existence of factors such as differences in machine tool accuracy, grinding wheel accuracy and wear, the quality of tool grinding will be affected. If there is a problem with the quality of the tool during a certain grinding, it will cause tool waste and increase production costs. Detecting the tool during the grinding process can detect the influence of the machine tool and the grinding wheel on the tool grinding quality in time, and avoid batch defective products due to quality problems such as tool geometry, angle, and surface roughness. Therefore, it is very necessary to inspect the tool quality during the grinding process.

Existing technology detects the quality of cutting tools. Most enterprises use a single-function testing instrument to detect a certain dimension or angle of the cutting tool. The type detection instrument has the following disadvantages: 1. It can only detect a certain index of the tool, with a single function and low detection efficiency; 2. A variety of tool detection instruments cannot be neatly stored, placed in a mess, making it difficult to find, and delaying production time ; 3. Generally, the contact detection with the tool is carried out, and repeated contact will cause wear and tear, resulting in inaccurate detection; 4. The current single-function detection instrument detection benchmark is not consistent with the tool grinding manufacturing benchmark, and the detection accuracy is low. Some enterprises use intelligent testing instruments, but such instruments are expensive.
