Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments more apparent, the present invention is described in further detail below with reference to the accompanying drawings and the embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the utility model and are not intended to limit the utility model.

Embodiments substantially as shown in fig. 1-4, a bearing installation in position detection system includes,

and the measuring module comprises a displacement sensor 1, and the distance value between the end surface 6 of the bearing and the shaft end 7 of the wheel pair can be obtained through the moving distance of the displacement sensor 1. And then the measuring module sends the distance value to the measurement and control module.

And the measurement and control module is connected with the measuring module, and after the measurement and control module receives the measured value detected by the measuring module, the measurement and control module can judge whether the value exceeds a standard value between the end surface 6 of the bearing and the shaft end 7 of the wheel pair. When the measured value is consistent with the standard value or within the allowable error range, the normal installation between the bearing and the wheel pair is indicated; when the measured value exceeds or is less than the standard value or is not within the allowable error range, the improper installation between the bearing and the wheel pair is indicated, and the bearing needs to be reinstalled. The measurement and control module is an industrial personal computer. The specific determination process of the measurement and control module is the prior art, and is not described herein.

The measurement and control module also has a control function and can be used for controlling other modules.

The displacement sensor 1 in the measuring module is fixedly arranged on the positioning part 2, and the relative positions of the displacement sensor 1 and the positioning part 2 are fixed. Meanwhile, the positioning member 2 is connected to the mover 203, and when the mover 203 moves, the positioning member 2 moves. When the positioning element 2 moves, the displacement sensor 1 will then also move.

When the displacement sensor 1 moves with the mover 203, the displacement sensor 1 will first abut against the axle end 7 of the wheel pair, since the displacement sensor 1 is at the same level as the axle end 7 of the wheel pair. Then, because the positioning element 2 is not yet in contact with the bearing end face, the positioning element 2 will continue to move under the driving of the moving element (at this time, the displacement sensor 1 is supported by the shaft end 7 of the wheel pair, and the displacement sensor 1 is in a static state), until the positioning element 2 also supports the bearing end face, the positioning element 2 will not move any more. The specific movement process can refer to fig. 3 and 4.

In order to enable the positioning element 2 to abut completely against the bearing end face, the positioning element 2 is provided as a positioning fork 201. The middle part of the positioning fork 201 is provided with a U-shaped or V-shaped accommodating groove 202. The receiving groove 202 can receive the wheel axle of the wheel pair therein, so that the positioning fork 201 can abut against both sides of the end surface 6 of the bearing, respectively.

In order to avoid tilting the wheelset against movement when the locating element 2 is in contact with the bearing, the locating element 2 and the displacement sensor 1 are preferably arranged parallel to the wheelset.

The displacement sensor 1 in this embodiment is preferably a contact type displacement sensor 1, and when the displacement sensor 1 contacts with the shaft end of the wheel pair, the displacement sensor 1 moves, so that the measurement is more accurate.

Because the wheel pair to be arranged is positioned in the wheel pair conveying line, when the wheel pair needs to be detected, the measuring module can extend into the wheel pair conveying line under the action of the translation part 4, so that the wheel pair is measured; when the wheel set measurement is finished, the measuring module is taken out of the wheel set conveying line by the translation part 4. Meanwhile, when the measuring module is driven by the lifting part 3 to lift, the translation part 4 can drive the measuring module to be far away from the wheel set, so that the wheel set is prevented from blocking the movement of the measuring module.

The lifting part 3 is connected with the translation part 4, and the lifting part 3 can drive the translation part 4 to lift up and down. Meanwhile, the measuring module is arranged on the translation part 4, so that the measuring module can ascend and descend along with the translation part 4. When the measuring module goes up and down, the measuring module can move to different heights, and then the measuring module can be matched with wheel sets with different heights.

Lifting unit 3 and translation portion 4 all link to each other with observing and controlling the module to make lifting unit 3 and translation portion 4's motion more accurate.

The lift portion 3 specifically is vertical linear module, is provided with support piece on the sliding part of vertical linear module, installs translation portion 4 on the support piece, and support piece supports translation portion 4. Meanwhile, in order to ensure the stability of the lifting part 3, the lifting part 3 is installed on the bracket.

The translation section 4 is embodied as a horizontal linear module. The sliding part of the horizontal linear module is mounted with a mover 203 in the measuring module.

In order to determine the position of the slide in the horizontal linear module (the slide is directly connected to the measuring module), a position sensor is then arranged on the horizontal linear module. The position sensor is specifically a photoelectric sensor, and the sliding part is provided with a sensing block which is used for being matched with the photoelectric sensor. When the sliding part moves to different positions, the sensing part is also located at different positions, and then the sensing part is matched with the photoelectric sensors at different positions.

Photoelectric sensor is located the left and right sides both ends of horizontal linear module, and then can judge the position that measuring module is located through photoelectric sensor. The photoelectric sensor is directly connected with the measurement and control module.

In order to detect the bearings at the two ends of the wheel pair, two measuring modules and two motion modules are respectively arranged. The measuring module can detect the bearings at two ends, and the moving module supports the measuring module and enables the measuring module to be matched with wheel sets of different sizes.
