Problems solved by technology
Due to the tolerance of thread processing, the measurement tolerance of the product will be tightened or relaxed after the transfer, and the position degree cannot be accurately measured
In addition, the existing scheme only measures the position degree in the X and Y directions, and the position degree in the Z direction lacks detection, which has certain limitations.

Embodiment Construction
[0017] The present invention will be described in detail below in conjunction with accompanying drawing:
[0018] Embodiment: As shown in the accompanying drawings, this kind of quantitative detection mechanism applied to the ball head position of the swing arm assembly mainly includes a base 1, which is connected to the detection platform 3 through a slide rail 2, and detects the middle position of the platform 3 A ball pin cone fitting block 4 is set at the place, which can fit with the ball stud pin 5 of the swing arm assembly and move with the movement of the center of the ball. The left side of the detection platform 3 is equipped with an X-direction dial gauge 6 for measuring The position deviation in the horizontal direction of the center of the sphere, the front part of the detection platform 3 and the X-direction dial indicator 6 are vertically installed with a Y-direction dial indicator 7 for measuring the position deviation in the vertical direction of the center of ...

The invention discloses a quantitative detection mechanism and method applied to the position degree of a ball head of a swing arm assembly and relates to the field of automobile part detection. The quantitative detection mechanism mainly comprises a base, the base is connected with a detection platform through a slide rail; a ball pin conical surface fitting block is arranged in the middle of thedetection platform; an X-direction dial indicator is installed on a left side of the detection platform and is used for measuring the position deviation of a sphere center in a horizontal direction,a Y-direction dial indicator is installed on a front portion of the detection platform and is used for measuring the position deviation of the sphere center in a vertical direction, and a Z-directiondial indicator is installed on a right side of the detection platform in the vertical direction and is used for measuring the position deviation of the sphere center in the vertical direction. The quantitative detection mechanism has the advantages that the ball pin conical surface fitting block is used for measuring by taking a conical surface of a swing arm assembly ball pin as a reference, thetransfer tolerance is effectively reduced, the position degree can be quantitatively measured, the problem that the position degree in a Z direction is lack of detection is solved, the measurement visualization and the measurement accuracy are improved, the process can be better optimized, the debugging period of a manufacturing link is shortened, and the qualification rate of products is improved.
Description
technical field [0001] The invention relates to the field of auto parts detection, in particular to a mechanism and method for quantitatively detecting the position degree of a ball head of a swing arm assembly. Background technique [0002] The position of the center of the ball head needs to be detected after the reproduction of the swing arm assembly of the automobile is completed. The existing technical solution uses the method of transferring the position of the center of the ball to the position of the threaded bolt at the end of the ball head for measurement. Due to the tolerance of thread processing, the measurement tolerance of the product will be tightened or relaxed after the transfer, and the position degree cannot be accurately measured. In addition, the existing solutions only measure the position degree in the X and Y directions, and the position degree in the Z direction lacks detection, which has certain limitations.
