Description

Technical Field

[0001] The invention relates to the field of bearing inner hole detection, and in particular to a bearing inner hole detection machine. Background Art

[0002] The internal grinding of bearing rings usually involves first feeding the workpiece into a grinder for semi-automatic or automatic processing, and then manually measuring the inner diameter of the bearing.

[0003] At present, the patent with application publication number "CN117563959A" discloses a bearing inner hole detection and classification equipment, including an equipment frame and a turntable mechanism, a belt conveyor mechanism, a roller mechanism, a measuring mechanism, a classification mechanism, an air supply device, a benchmarking mechanism and a controller arranged on the equipment frame, wherein the turntable mechanism, the belt conveyor mechanism, the roller mechanism, the measuring mechanism, the classification mechanism and the air supply device are all connected to the controller, the turntable mechanism is used to store and convey bearing workpieces to the belt conveyor mechanism, the belt conveyor mechanism is used to temporarily store bearing workpieces and convey bearing workpieces to a position to be detected, and the The roller mechanism includes a rotating mechanism for rotating the bearing workpiece and a material-dispensing mechanism for moving the position of the bearing workpiece. The measuring mechanism includes a lifting mechanism and a measuring pen installed on the lifting mechanism. The lifting mechanism can drive the measuring pen to move up and down. The measuring pen includes a pen body and two measuring balls located on both sides of the pen body. The measuring balls are connected to the controller. The benchmarking mechanism is connected to the air supply device and a standard bearing workpiece is arranged inside. The classification mechanism is used to classify the bearing workpieces after inspection. The classification mechanism cooperates with the benchmarking mechanism to place the standard bearing workpiece on the material-dispensing mechanism and transport it to the bottom of the measuring pen.

[0004] The comparative document uses a belt conveyor mechanism to horizontally transport the bearings to the roller mechanism, measuring mechanism, and classification mechanism for testing. However, since the bearings are all coated with oil to prevent rust, when the bearings are pushed, oil stains will inevitably fall on the material channel slot plate. Since the material channel slot plate is placed horizontally, the oil stains will accumulate at this time and need to be manually cleaned. Once they are not cleaned, and there is no limit on the top, the bearings will tilt, resulting in deviations in the test results. Moreover, the standard parts and the unloading parts use the same pneumatic finger, and there are oil stains and dirt on the tested bearings. At the same time, the standard parts move horizontally on the top of the material channel slot plate, which can easily contaminate the standard parts, resulting in deviations in the standard parts. Moreover, the belt conveyor is used to transport the bearings. Since it is transported horizontally, in order to enter the material channel slot plate individually, there must be a guide (see comparative document Figure 4 ), and the bearings entering the belt conveyor from the turntable mechanism will not be 100% aligned with the guide. Once the guide is slow due to the bearing guide, the bearing will be transported slowly, and then the rear bearing will be on top. The two bearings will be crowded with each other at the guide, resulting in bearing accumulation. Summary of the invention

[0005] The purpose of the present invention is to provide a bearing inner hole detection machine, which has the advantages of reducing the influence of oil stains on the bearing itself on the detection, limiting the bearing conveying, queuing the bearings in sequence and sending them between the upper pressure wheel and the lower pressure wheel of the measuring bracket, effectively classifying the bearings, and preventing the standard bearings from being contaminated.
