Detailed implementation manners

[0026] In this embodiment, as Figure 1 and Figure 2 shown, a bearing size detection device includes a mounting shell 1. A measuring assembly 2 is installed in the mounting shell 1. The measuring assembly 2 is used to measure the inner diameter and outer diameter of the bearing simultaneously. The measuring assembly 2 includes a scale plate 21, a slide bar 22, a baffle 23, a rack plate 24, a driving member 25, and a clamping plate 26. The scale plate 21 is fixedly connected to the mounting shell 1. The slide bar 22 is inserted into the limiting groove of the scale plate 21. One end of the slide bar 22 is fixedly connected to the baffle 23. The other end of the slide bar 22 is fixedly connected to the rack plate 24. The clamping plate 26 is fixedly connected to the end of the baffle 23 away from the slide bar 22. The driving member 25 is used to drive the rack plate 24 to move horizontally, so as to drive the clamping plate 26 to abut against the inner wall of the bearing.

[0027] Thus, the mounting shell 1 is closed by using the scale plate 21. The mounting shell 1 is placed on the side of the measured bearing. The two clamping plates 26 are inserted into the inner hole of the measured bearing. Under the action of the driving member 25, the two rack plates 24 move towards each other.

The two clamping plates 26 respectively abut against the inner wall of the measured bearing, so that the axis of the bearing coincides with the center line of the scale plate 21. The inner and outer diameter dimensions of the measured bearing are determined through the scale on the scale plate 21.

[0028] Specifically, scales are processed at the axis position of the scale plate 21, and a chute adapted to the slide bar 22 is processed on the scale plate 21. The baffle 23 serves to connect the clamping plate 26 and the slide bar 22. The clamping plate 26 is processed into a rhombus shape.

The motor 253 provides power for the rotation of the rotating shaft 251, and the rotating shaft 251 is used to drive the gear 252 to rotate.

[0031] In some embodiments, as Figure 4 shown in the figure, an adjusting assembly 3 is installed on the mounting shell 1.

The telescopic member 34 is used to adjust the use height of the connecting seat 33, and the base 35 is used to support the telescopic member 34.

[0032] Specifically, the fixing frame 31 is processed into a U shape. Two bolts 32 are provided for connecting to the mounting shell 1. Threaded holes are annularly distributed on both sides of the fixing frame 31. The telescopic member 34 changes the use height between the base 35 and the fixing frame 31. The base 35 is processed into a "work" shape;

[0033] In addition, other fixing methods can be adopted between the fixing frame 31 and the mounting shell 1 to replace the connection method of the bolts 32.

[0034] In some embodiments, as Figure 4 shown in the figure, the telescopic member 34 includes a cylinder 341, a support rod 342, a threaded pin 343 and a nut 344. The bottom end of the cylinder 341 is fixedly connected to the base 35. The support rod 342 is inserted into the through groove of the cylinder 341.

[0040] The working principle of the present application will be described below with a preferred embodiment:

[0041] When measuring the inner diameter and outer diameter of a bearing, the bearing is placed on the mounting shell 1, and the two clamping plates 26 are located in the inner ring of the bearing. Subsequently, the motor 253 is started. The motor 253 drives the rotating shaft 251 to rotate through the coupling, and the gear 252 moves together with the rotating shaft 251. Furthermore, the gear 252 drives the two rack plates 24 to move towards each other. The rack plates 24 drive the clamping plates 26 to move in the opposite direction on the same axis through the sliding rods 22 and the baffle plates 23. As the clamping plates 26 move, the axis of the bearing is forced to coincide with the center line of the scale plate 21. At this time, the inner diameter and outer diameter of the bearing are read through the scale of the scale plate 21. When the bearing is suspended and installed on the equipment, the fixing frame 31 and the mounting shell 1 are connected through the bolt 32, and the overall structure is supported by the base 35. Subsequently, the support rod 342 is moved in the cylinder 341. The support rod 342 drives the mounting shell 1 to move upward through the connecting seat 33 and the fixing frame 31. According to the inclination angle of the bearing installation, the fixing frame 31 is rotated in the connecting seat 33. After the fixing frame 31 drives the mounting shell 1 and the bearing to be parallel, the use position of the fixing frame 31 in the connecting seat 33 is fixed by using the positioning pin 331. Subsequently, the axis of the bearing is made to coincide with the center line of the scale plate 21, and the scale plate 21 is read to measure the inner and outer diameter dimensions of the suspended installed bearing.
