Thickness detection device for variable-thickness sheet stamping parts

Abstract

A thickness detection device for variable-thickness sheet stamping parts comprises a rotary base, a large arm, a small arm, a wrist and a gripper. One end of the large arm is hinged to the rotary base, and a large arm driving motor used for driving the large arm to swing is arranged at the hinge point; the other end of the large arm is hinged to one end of the small arm, and a small arm driving motor used for driving the small arm to swing is arranged at the hinge point; the other end of the small arm is hinged to one end of the wrist, and a wrist driving motor used for driving the wrist to swing is arranged at the hinge point; a gripper rotation driving motor is fixedly mounted at the other end of the wrist, and the root of the gripper is fixedly connected with a motor shaft of the gripper rotation driving motor. The front end of a palm portion of the gripper is provided with two measurement fingers namely a main measurement finger and an auxiliary measurement finger, a dial gauge is fixedly mounted at the fingertip of the main measurement finger, and a measurement head of the dial gauge is matched with the fingertip of the auxiliary measurement finger. The main measurement finger and the auxiliary measurement finger are connected with the palm portion of the gripper through a measurement finger opening-closing driving 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...

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.
