Description

Technical Field

[0001] The utility model relates to the technical field of riveting pin workpiece detection, in particular to a riveting pin workpiece parallelism and symmetry detection device. Background Art

[0002] In the modern machinery manufacturing process, rivet pin workpieces are widely used in various mechanical equipment and structures as an important connecting element. The parallelism and symmetry of rivet pin workpieces are important parameters that affect the stability and reliability of mechanical equipment. If the parallelism or symmetry of the rivet pin workpiece does not meet the requirements, it will cause assembly errors, which will affect the overall performance and service life of the mechanical equipment. Therefore, accurate detection of the parallelism and symmetry of the rivet pin workpiece is an important part of ensuring product quality.

[0003] The traditional rivet pin workpiece detection method mainly relies on manual measurement and visual inspection, which is not only time-consuming and labor-intensive, but also has large subjective errors and uncertainties. With the development of technology, more and more automated detection equipment is applied in the production process to improve detection efficiency and accuracy. Prior art CN201637370U discloses a pin height gauge, including an inverted step pin height gauge body, on which an upper step surface, a lower step surface, and a reference surface are respectively arranged from top to bottom, and the upper step surface, the lower step surface, and the reference surface are arranged in parallel; the height difference between the upper step surface and the lower step surface is within the range of the tolerance limit, and the pin height can be easily judged whether the pin height is qualified while detecting the measured pin height. However, this technology is mainly aimed at the detection of pin height, but fails to effectively solve the detection problem of parallelism and symmetry of rivet pin workpieces, which is not convenient for wide application in actual production. In addition, most of the detection equipment on the market are complex in structure, high in cost, and cumbersome in operation, and there are few special detection devices for the parallelism and symmetry of rivet pin workpieces. Therefore, there is an urgent need for a device with a simple structure, low cost, easy operation and the ability to accurately detect the parallelism and symmetry of riveted pin workpieces to meet the needs of actual production.

The parallelism and symmetry detection component 3 successfully inserts the detection component into the embedding groove 401, indicating that the parallelism of the workpiece is good, and the embedding groove 401 of the rivet pin workpiece 4 is parallel to the square block 402; after the parallelism and symmetry detection component 3 is inserted into the embedding groove 401, the two sides are symmetrical, indicating that the symmetry of the workpiece meets the requirements, and the embedding groove 401 of the rivet pin workpiece 4 is symmetrical.

[0027] The connecting rod fixing component 2 includes a pair of symmetrically arranged connecting rod clamping blocks 201 and positioning connecting pins 202, a gap 203 is provided between the connecting rod clamping blocks 201, and the parallelism and symmetry detection component 3 is inserted into the gap 203.
