Description

TECHNICAL FIELD

[0001] The application belongs to the field of bearing outer circle groove processing, and particularly relates to a bearing outer circle groove on-line detection full-automatic processing grinding machine. BACKGROUND

[0002] Bearing is an important part in contemporary mechanical equipment. The bearing includes a bearing inner ring and a bearing inner ring, wherein the outer groove of the bearing inner ring is ground on a numerical control automatic grinding machine for the bearing inner ring. After traditional outer circle groove grinding, the outer circle groove diameter needs to be detected to serve as a correction basis for the next grinding parameter. When the outer groove diameter is detected, manual detection is generally adopted, which is prone to cause large error and low detection precision, and leads to difficulty in guaranteeing the product quality in the later production. Meanwhile, after the outer circle groove size fails to meet the requirements, the outer circle groove needs to be re-clamped for re-grinding, so that multiple installation bases are formed, the machining precision is affected, and manual clamping is still adopted at present, thereby affecting clamping consistency and machining efficiency.

[0003] In view of this, the present application is proposed to solve the problem. SUMMARY

[0009] The present application adopts the following technical scheme:

[0010] The present application adopts the following technical scheme:

[0011] Through the online detection assembly, the outer raceway diameter of the bearing is detected during the grinding process, so that the bearing only needs to be installed once to complete the control of the required grinding size requirement, and the steel ring transfer mechanical hand assembly can realize automatic feeding and discharging, thereby completing the efficient processing.

[0012] The second innovation of the application is that, in order to adapt to the grinding processing of thin / thin bearing steel rings, the traditional outer raceway grinding processing is to expand the inner ring from the inside by using multiple rollers / claws, and then grind the outer raceway with a grinding wheel. When the rollers / claws expand the inner ring, the pressing force cannot be guaranteed, which may cause permanent damage to the inner diameter of the inner ring. Moreover, the rollers / claws are distributed in equal intervals in the circumferential direction, and cannot completely cover the inner wall of the bearing inner ring. Therefore, the clamping may cause the bearing inner ring to be squeezed and deformed. Therefore, the following improvements are made:

The servo motor, the rotary shaft and the rotary disc are mounted on the mounting frame one. The output end of the servo motor is connected with the rotary disc through the rotary shaft.
