Abstract

The invention discloses a measurement machine of the external dimension of a bearing. The measurement machine comprises a feeding mechanism, a carrying mechanism, a measurement mechanism and a discharging mechanism. The measurement mechanism is located on the down stream of the feeding mechanism, and the discharging mechanism is located on the down stream of the measurement mechanism which comprises a bearing upper end surface measurement mechanism, a bearing lower end surface measurement mechanism, a bearing inner hole diameter measurement mechanism and a bearing side surface measurement mechanism, wherein a bearing turnover mechanism is arranged between the bearing upper end surface measurement mechanism and the bearing lower end surface measurement mechanism. The measurement machine isfurther provided with a control system, the feeding mechanism, the carrying mechanism, the bearing upper end surface measurement mechanism, the bearing turnover mechanism, the bearing lower end surface measurement mechanism, the bearing inner hole diameter measurement mechanism, the bearing side surface measurement mechanism and the discharging mechanism are electrically connected with the controlsystem. The measurement machine takes the place of the human eyes to achieve automatic detection of the bearing, the eyes of workers are liberated, and the labor intensity of the workers is reduced.Meanwhile, the measurement efficiency of the bearing can be effectively improved, the measurement precision is high, and the practicability is high.

Description

technical field [0001] The invention relates to the technical field of bearing detection, in particular to a bearing appearance dimension detection machine. Background technique [0002] Bearings are components that fix and reduce the friction coefficient of loads during mechanical transmission. It can also be said that when other parts move relative to each other on the shaft, it is used to reduce the friction coefficient in the process of power transmission and keep the center of the shaft fixed. Bearings are an important part of modern mechanical equipment. Its main function is to support the mechanical rotating body to reduce the friction coefficient of the mechanical load during the transmission process of the equipment. According to the different friction properties of moving elements, bearings can be divided into two types: rolling bearings and sliding bearings.

AI Technical Summary

Problems solved by technology

[0003] For the appearance inspection of the bearing, it is mainly to detect whether there are scratches and rust on the outer surface of the bearing and whether the rivets on the upper and lower end faces are riveted well and whether there is a lack of steel balls. For the size inspection of the bearing, it is mainly to detect whether the diameter of the inner hole of the bearing is qualified. At present Manual inspection is often used. Manual inspection not only has a large detection error, but also has a high degree of eye use by workers, which is easy to induce various eye diseases. Manual inspection uses hands to directly touch the bearing to pollute the outer surface of the bearing, and manual inspection can only detect one bearing at a time. The detection efficiency is also very low

[0004] In addition, there are also bearing automatic testing machines on the market, but they are simple in structure, single in function, and low in accuracy. The above-mentioned machine tools are respectively equipped with two inductors for detecting the two ends of the bearing, a transmission device for clamping the bearing and pushing the bearing against the sensor, and a supporting device for driving the displacement of the bearing. The two inductors and the transmission Two continuous openings are formed between the devices for the bearing to be displaced by the supporting device, and a conversion piece for flipping the bearing is provided between the two continuous openings. The bearing is pushed up by the transmission device on a continuous opening and a sensor interferes with any detection. After one end face, it is displaced into the conversion part by the supporting device, turned over and then moved to another continuous opening, and then the transmission device pushes the bearing from the other continuous opening to the other end face in conflict with another sensor, the structure Simple, can only detect the upper and lower end faces, the accuracy is low, and the detection range is limited
