A device for detecting the thickness of sheet metal stamping parts with variable thickness

Abstract

A thickness detection device for sheet metal stamping parts with variable thickness, including a rotary base, a large arm, a small arm, a wrist and a claw; one end of the large arm is hinged on the rotary base, and a device for driving the large The boom drive motor for arm swing; the other end of the boom is hinged with one end of the forearm, and a forearm drive motor for driving the swing of the forearm is arranged at the hinge point; the other end of the forearm is hinged with one end of the wrist, and A wrist drive motor for driving the wrist swing is arranged at the hinge point; the other end of the wrist is fixed with a claw rotation drive motor, and the root of the claw is fixedly connected with the motor shaft of the claw rotation drive motor; There are two measuring fingers at the front end, which are respectively recorded as the main measuring finger and the auxiliary measuring finger. A dial indicator is fixed on the fingertip of the main measuring finger, and the measuring head of the dial indicator matches the fingertip of the auxiliary measuring finger; The measuring finger and the secondary measuring finger are connected with the palm of the hand through the measuring finger opening and closing drive mechanism.

Description

technical field [0001] The invention belongs to the technical field of plate thickness detection, and in particular relates to a thickness detection device for plate stamping parts with variable thickness. Background technique [0002] Stamping parts of variable thickness plates usually have special geometric shapes, and in some special fields, the thickness and dimension requirements for stamping parts of variable thickness plates are very strict, so the products must pass thickness inspection before leaving the factory. [0003] At present, the measuring tools used for sheet thickness detection are mainly micrometers and vernier calipers. However, due to the special geometry of sheet metal stamping parts with variable thickness, there are often some key parts that cannot be directly measured by traditional measuring tools. Therefore, only Indirect measurement is carried out by other tools, and the measurement accuracy of indirect measurement method is low. [0004] In add...

AI Technical Summary

Problems solved by technology

[0003] At present, the measuring tools used for sheet thickness detection are mainly micrometers and vernier calipers. However, due to the special geometry of sheet metal stamping parts with variable thickness, there are often some key parts that cannot be directly measured by traditional measuring tools. Therefore, only Indirect measurement by other tools, and the measurement accuracy of indirect measurement method is lower

[0004] In addition, since the thickness detection of the product before leaving the factory is mostly full-scale detection, and the measurement process can only be carried out manually, the labor intensity of the workers is very high, and the measurement efficiency is very low, and the human error of manual measurement is relatively large. Obviously, it will lead to large fluctuations in measurement accuracy

[0005] Therefore, at this stage, it is still difficult to realize the industrialization of the thickness detection of stamped parts of variable thickness sheet metal, because it is urgent to design a new thickness detection device, which can meet the industrial detection requirements of the thickness of stamped parts of variable thickness sheet metal.
