Description

Technical Field

[0001] The utility model relates to the technical field of suspended detection devices, in particular to a suspended detection device for the center position of an outer ball of a ball cage retainer. Background Art

[0002] When producing ball cage cages, the outer ball center position needs to be detected after the ball cage cages are completed. However, the existing detection method generally adopts lever comparison detection. However, there is a linear proportion problem in the lever comparison detection. For example, in the patent number "CN214502274U" and the patent name "A hole position detection device for a six-hole ball cage cage", the hand wheel is rotated, and the second screw is rotated, and the second screw is rotated to drive the clamping plate to slide inside the mounting plate. The clamping plate then cooperates with the mounting plate to fix the mounting plate to the edge of the detection table. The sponge pad is set to effectively protect the surface material of the detection table. Then the cover plate on one side of the sliding fixing strip is exposed. After that, the first screw is rotated again, and the first limit block and the second limit block are locked. The threads of the first and second limit blocks are arranged in reverse, and the first screw rod rotates to drive the first limit block and the second limit block to slide toward or away from each other. When sliding toward each other, the ball cage holder is clamped, and when sliding away from each other, the ball cage holder is released. The setting of the guide rod greatly improves the stability of the first limit block and the second limit block when sliding. Then, the handle is pulled, and the handle drives the card block to slide. The spring is extended, and the detector mounting block is slid into the inside of the mounting strip, and the card block is released. The spring resets and drives the card block to slide into the card slot on one side of the detector mounting block. The operation is flexible, and the ball cage holder is fixed by the limit structure. The ball cage holder hole position detection instrument is quickly installed by the installation structure, which improves the detection effect and the detection is accurate. The ball cage holder is easy to fix and the detection efficiency is improved. However, the above device still has the following problems in actual use:

[0003] During use, the above-mentioned device clamps and fixes the ball cage holder through the cooperation between the first limit block and the second limit block. However, when it is necessary to detect the center position of the ball outside the ball cage holder, the detection head will generally fit the outside of the ball cage holder. Therefore, the above-mentioned clamping mechanism will affect the detection of the detection head when in use, and its use has limitations.

[0004] Therefore, we proposed a suspended detection device for the center position of the outer ball of the ball cage retainer, which can solve the above problems well. Utility Model Content

[0005] The purpose of the utility model is to provide a suspended detection device for the center position of the outer ball of a ball cage holder, so as to solve the problem in the current market proposed by the above-mentioned background technology that when the center position of the outer ball of the ball cage holder needs to be detected, the detection head generally fits onto the outer side of the ball cage holder, so the above-mentioned clamping mechanism will affect the detection of the detection head when in use, resulting in limitations in use.
