Problems solved by technology

[0005] This technical solution can prevent stamping parts from shifting during detection and measurement, and the overall image of stamping parts is transmitted by ultrasonic characteristic wave transmission and echo reception, and the measurement and imaging are compared and unified to avoid uneven parts of stamping parts. Accuracy is affected, but this technical solution can only detect stamping parts of the same batch, and cannot be applied to stamping parts of different specifications, and can fix stamping parts, resulting in limitations of this technical solution

Embodiment approach

[0029] As an embodiment of the present invention, the swing range of the hinge arm 10 around the support arm 7 is 160 degrees; the middle part of the hinge arm 10 is fixedly connected with the middle part of the support arm 7 with an elastic rope 14; After the stamping part is detected, the lifting unit 3 is started to raise the stamping part to be taken out. Because the rubber suction cup 13 has an adsorption force on the outer wall of the stamping part, the stamping part will drive the rubber suction cup 13 to move upward. The rubber suction cup 13 and the hinge arm 10 The connection mode is hinged, so it will drive the hinge arm 10 to move upward. Because the hinge arm 10 is fixed by the friction force generated between the hexagon socket head screw 12 and the support arm 7, and its friction force is limited, it will drive the hinge arm 10 to move upward. Angle offset, in the next measurement, the stamping part cannot be fixed, which affects the detection of the stamping par...

Abstract

The invention belongs to the technical field of automobile detection, and particularly relates to an automobile stamping part testing fixture which comprises a base, a manipulator, a lifting unit, anelectromagnet, a clamping plate, a positioning pin and a supporting arm. The cross section of the base is square, a lifting unit is arranged in the center of the upper end of the base, an electromagnet is arranged above the lifting unit, and the section of the electromagnet is circular. A rubber plate is adhered to the upper end of the electromagnet, and the section shape of the rubber plate is the same as that of the electromagnet. The lifting unit is used for driving the electromagnet to ascend and descend, a manipulator is arranged at the corner of the upper end of the base, the tail end ofthe manipulator can move to the center above the base, and a detection unit is arranged at the tail end of the manipulator. According to the invention, the four supporting arms are matched with the electromagnet and the detection unit, so that the testing fixture can be suitable for stamping parts with different sizes and can be used for detecting the stamping parts, the manufacturing cost of thestamping part testing fixture is reduced, and the product detection efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of automobile detection, and in particular relates to a detection tool for stamping parts of automobiles. Background technique [0002] Checking fixture is a tool specially made by the machinery manufacturing industry to control various mechanical dimensions of products. It can be used to measure and evaluate the dimensional quality of parts. During the life cycle of the parts, the inspection of the parts is realized through the inspection tool, and the parts are accurately installed on the inspection tool, and then the profile, material edge and hole of the part are inspected through visual inspection, inspection tools and measuring tables, so as to ensure Quick judgment of part quality status during production. [0003] At present, as the types of stamping parts of automobiles increase, the required stamping parts inspection tools will increase accordingly, and one inspection tool corresponds to one stamp...
