Description

Technical Field

[0001] The utility model relates to the technical field of bearing detection, in particular to a detection tool for precision bearings. Background Art

[0002] Bearings are an important component in contemporary mechanical equipment. Their main function is to support mechanical rotating bodies, reduce the mechanical load friction coefficient of the equipment during the transmission process, and ensure its rotation accuracy. The working principle of bearings is based on the principles of lubrication and rolling / sliding friction. A lubricating film is formed in the bearing through appropriate lubricants, so that the rolling elements roll on the contact surface instead of sliding, thereby reducing energy loss and heat generated by friction.

[0003] When precision bearings are mass-produced, they need to be inspected to ensure their accuracy. Using unified bearing inspection tooling can greatly improve testing efficiency, facilitate communication and collaboration between inspectors, and avoid repeated purchases and waste of resources.

[0004] The applicant has searched the existing bearing detection tooling. At present, the common detection method for bearings is that workers use instruments such as vernier calipers and dividers to detect, or use bearing detectors to replace detection. On the one hand, the manual detection efficiency is low and the detection result error is large. On the other hand, the bearing detector cannot fully meet the detection requirements of the bearing disc. The bearing disc detection tooling disclosed in Chinese patent number CN208860265U includes a bottom plate, the upper side wall of the bottom plate is fixedly connected to two symmetrically arranged columns, a top plate is fixedly connected between the two columns, and a measuring mechanism is provided on the lower side wall of the top plate. The side walls on the opposite sides of the two columns are rotatably connected to a rotating shaft, and the two rotating shafts are fixedly connected to a mounting plate. Two symmetrically arranged baffles are fixedly connected between the two mounting plates, and the side walls on the opposite sides of the two mounting plates are provided with a clamping mechanism. It is provided by setting a cylinder, a support plate, a first motor, a moving plate and a vernier caliper, starting the cylinder, the cylinder drives the support plate to descend, the support plate drives the first motor to move downward, the first motor drives the moving plate to move, and the moving plate drives the vernier caliper to move downward, and then the diameter of the bearing disc is measured.

[0005] However, the applicant has found that, during use, only the outer wall diameter and the overall thickness of the bearing can be uniformly measured and detected simultaneously, and the distance between the inner walls of the bearing cannot be measured simultaneously, resulting in a narrow detection range.

[0006] Therefore, in view of the above problems, it is necessary for the applicant to design a detection tool for precision bearings to solve the problems. Summary of the invention
