Description

Technical Field

[0001] The utility model relates to the technical field of detection tools, in particular to a comprehensive position gauge with a detection pin locking structure. Background Art

[0002] Generally, a timing chain cover is often fixed on the side of an engine to protect the front end of the entire timing system. After the production of the timing chain cover is completed, it is necessary to detect its surface position, flatness, and hole position. Currently, the surface position and flatness of the timing chain cover are often detected by a coordinate measuring machine. However, the detection speed of the coordinate measuring machine is slow, and there is a risk of missed detection when detecting a large number of products. Currently, the hole position is often detected by a detection pin. However, the traditional detection pin adopts a spring structure. Pressing the spring drives the detection pin to detect the hole position. However, the spring will rebound after detection, and all holes cannot be detected simultaneously, resulting in a risk of missed holes. Summary of the Utility Model

The reference sliding platform 17 is arranged based on the hole position of the hole to be measured on the standard part where the flatness of the hole needs to be detected. The hole to be measured for detecting the flatness of the hole is located on the top surface of the part to be measured. When detecting the flatness of the corresponding hole, the dial indicator is removed from the placement plate 3, and the bottom of the sliding seat 33 is placed on the top of the reference sliding platform 17. The bottom surface of the sliding seat 33 and the top surface of the reference sliding platform 17 are both flat surfaces.

[0059] Working principle:

[0060] During detection, the installation direction of the part to be measured can be quickly determined conveniently through the pre-positioning column 14. The part to be measured 5 is subjected to reference positioning and fixation through the positioning assembly 22. After the part to be measured 5 is fixed on the bottom plate 1, its top surface is pressed and fixed through the first pressing assembly 15 to improve the installation stability of the part to be measured 5. When detecting the machined surface of the part to be detected 5 through the scanning gauge 31, the scanning gauge 31 is taken off the placing plate 3, and the through end and stop end of the scanning gauge 31 are sequentially passed through the gap between the machined surface of the part to be detected 5 and the reference positioning block 12. If the through end passes and the stop end stops, the position of the machined surface of the part is qualified; otherwise, it is unqualified. When detecting the hole flatness of the part to be detected 5 through the dial indicator 32, the dial indicator 32 is taken off the placing plate 3, and the measuring needle of the dial indicator 32 is rotated one week while being attached to the hole end face of the hole to be detected, and the value of the dial indicator 32 is read. If it meets the dimensional tolerance, it is qualified; otherwise, it is unqualified. Detecting the surface position and flatness of the part to be measured 5 through the scanning gauge 31 and the dial indicator 32 facilitates the detection of a large number of products and avoids missed detection.

[0061] When detecting the hole flatness of the part to be measured 5 through the first detection pin assembly 21 and the second detection pin assembly 13, the cover plate 2 is positioned and fixed above the top surface of the bottom plate 1 through the fixing assembly 22, and then the top surface of the cover plate 2 is pressed and fixed through the second pressing assembly 16 to improve the fixing stability of the cover plate 2. Subsequently, the hole flatness of the corresponding holes on both sides of the part to be measured 5 is detected through the first detection pin 212 and the second detection pin 132. If the detection ends of both the first detection pin 212 and the second detection pin 132 can successfully penetrate into the corresponding holes to be detected, the hole flatness of the part to be measured 5 is qualified; otherwise, it is unqualified. After the first detection pin 212 is inserted into the corresponding hole to be detected, it will not rebound, and multiple first detection pins 212 can act simultaneously to detect the hole position degrees of multiple hole positions on the top surface of the part to be measured 5 at the same time, avoiding missed detection.
