The beneficial effect who so sets up is: by adopting the scheme, when the surface roughness of the bearing ring channel needs to be observed, the bearing ring needing to be observed is placed on the raceway between the first roller and the second roller, then a microscope is placed on the channel of the ring for observing burrs and scratches on the surface of the channel to obtain the surface roughness of the bearing ring to be observed, and because the first roller and the second roller are both rotatably disposed on the placing table, so that the first roller or the second roller can be operated to rotate the ring when observing, and the rotation angle of the first roller or the second roller can be controlled when observing so as to obtain the position of the channel surface to be observed, therefore, the device has stronger controllability, and the ferrule cannot deviate when the device drives the ferrule to rotate through the roller, so the device has higher operation stability compared with the device which directly rotates the ferrule manually.

The invention is further provided with a base, the bottom surface of the base is obliquely arranged, and one end of the placing table close to the ground is provided with a contact rod for contacting the outer ring of the bearing.

The beneficial effect who so sets up is: adopt above-mentioned scheme, because the channel of bearing inner race is at the internal perisporium of bearing inner race, so when the vertical channel of placing on the raceway of bearing inner race the inconvenient channel of observing the bearing inner race of microscope, thereby set up the base into the bearing inner race slope that the slope made needs to observe, and then the channel of bearing inner race is conveniently observed to microscope, and adopt the conflict pole to support the bearing inner race that needs the observation, make the bearing inner race can not squint, because the channel of bearing inner race is at the periphery wall of bearing inner race, so vertical placing or the slope is placed the channel that the microscope can all observe the bearing inner race.

The invention is further provided that the first roller and the second roller are provided with operating rotating buttons extending outwards from the placing table, the outer surface of the placing table is provided with a dial along the circumferential direction of the operating handle, the operating rotating buttons are provided with scale marks, and the scale marks are arranged in alignment with the dial.

The beneficial effect who so sets up is: adopt above-mentioned scheme, the operation knob has made things convenient for the first roller of observer or second ball to rotate, and set up the scale mark on the operation knob, and the scale mark has aimed at the calibrated scale of placing the platform surface, so when the operation knob rotates, can audio-visually see operation knob pivoted turned angle at every turn, so in after the operation knob has rotated the steel ball at every turn, turned angle's record has avoided the observer to carry out repeated observation to the steel ball surface that has observed, has increased observation efficiency.

Detailed Description

As can be seen from FIGS. 1 to 4, the invention discloses an auxiliary device for observing a bearing ring channel, which comprises a base 1, wherein a placing table 2 is arranged on the base 1, a positioning device 3 for placing a bearing ring is arranged on the placing table 2, the positioning device 3 comprises a first roller 31 and a second roller 32, the first roller 31 and the second roller 32 are both rotatably arranged on the placing table 2, the first roller 31 and the second roller 32 are both arranged along the length direction of the placing table 2, and a raceway 33 for driving the bearing ring to rotate is formed between the first roller 31 and the second roller 32 at intervals. The beneficial effect who so sets up is: by adopting the scheme, when the surface roughness of the bearing ring channel needs to be observed, the bearing ring needing to be observed is placed on the raceway 33 between the first roller 31 and the second roller 32, a microscope was then placed on the channel of the ring to observe burrs and scratches on the surface of the channel to obtain the surface roughness of the bearing ring to be observed, and because both the first roller 31 and the second roller 32 are rotatably provided on the placing table 2, the first roller 31 or the second roller 32 can be operated to rotate the ferrule when viewed, and the rotation angle of the first roller 31 or the second roller 32 can be controlled at the time of observation to obtain the position of the surface of the channel desired to be observed, therefore, the device has stronger controllability, and the ferrule cannot deviate when the device drives the ferrule to rotate through the roller, so the device has higher operation stability compared with the device which directly rotates the ferrule manually.
