Description

Technical Field

[0001] This utility model belongs to the field of tooling and inspection technology, and relates to a rocker arm hole position measurement tool. This tool can quickly determine whether the position of three holes is qualified, reducing the time for sending and waiting for coordinate measuring machine inspection. Background Technology

[0002] The rocker arm of a car has an arc-shaped structure, such as Figure 7 As shown, the rocker arm 7 has a central mounting hole 71, a pin hole 72 penetrating its upper and lower end faces, a threaded hole 73 on one end side, and oil holes. The oil holes include a straight oil hole 74 that crosses the mounting hole 71 and the pin hole 73, and an inclined oil hole 75 that passes through the mounting hole 71 and the threaded hole 73. Although a traditional coordinate measuring machine can be used to detect the positional accuracy of each hole in the rocker arm, this method may be time-consuming and have a large measurement error, which is not conducive to quality control in on-site production.

[0003] Thus, instrument testing was developed. The relative position of the two ends of the hole to be measured was determined by measuring the rotation angle of the rocker arm. The rocker arm was initially fixed by setting a reference shaft on the base and inserting it through the rocker arm shaft mounting hole. The rocker arm was then reliably clamped on the base by using the cooperation of the limit block, the threaded hole guide block and the positioning pin. Then, the oil hole position measuring rod was used to sequentially pass through the straight oil holes on the U-shaped concave part of the rocker arm, the rocker arm shaft mounting hole and the threaded hole to determine whether the straight oil holes between each part were aligned.

[0004] However, the above-mentioned technologies are mainly for the positional accuracy detection of straight oil holes, and do not cover the positional accuracy detection of three holes: rocker arm threaded holes, straight oil holes, and inclined oil holes. Therefore, it is necessary to design a positional accuracy inspection tool that can detect the positional accuracy of the above three holes. Summary of the Invention

[0005] To address the problems of long testing time and large errors in existing rocker arm hole position measurement methods, this invention proposes a rocker arm hole position measurement tool that can be used for on-site testing, is easy to operate, and can measure the position of three holes: threaded holes, straight oil holes, and inclined oil holes.
