AI Technical Summary
Existing blank cutting devices for bearing processing are prone to positional shifts during the feeding process, resulting in low cutting accuracy and increasing subsequent grinding and production costs.
A guiding feeding mechanism is adopted. Through a synchronous moving mechanism and a first rotating mechanism, axial positioning is achieved by the friction between the guide wheel and the billet, and radial positioning is achieved by the rotation and stopping of the guide wheel, ensuring that the billet is accurately fed to the cutting station.
This improves the precision of blank cutting, reduces the need for subsequent grinding and regrinding, and lowers production costs.

Abstract
Description
Technical Field
[0001] This invention relates to the field of blank cutting device technology, and more specifically, to a blank cutting device for bearing processing. Background Technology
[0002] In the bearing manufacturing process, blank cutting is a crucial initial step. Its machining accuracy directly determines the quality of subsequent forging, turning, and grinding processes, thus affecting the final performance, reliability, and service life of the bearing. The dimensional accuracy, end-face flatness, and positional consistency of the blank after cutting are key prerequisites for ensuring the pass rate of the bearing's inner and outer rings. Bearing blanks are mostly rod-shaped structures. Before cutting, they must be precisely fed to the cutting station by a feeding mechanism. Therefore, the stability and accuracy of the feeding process, especially preventing positional shifts in the blank during feeding, are crucial for improving blank cutting quality and reducing scrap rates.
[0003] Currently, the feeding mechanism of existing blank cutting devices for bearing processing mostly adopts a simple conveying roller group or guide groove pushing structure. However, the conveying roller group or guide groove pushing structure lacks a radial limiting structure for the blank. During the conveying process, the blank is prone to lateral displacement due to the parallelism error of the roller group, roller surface wear, or the roundness deviation of the blank itself. This results in the blank end not being able to accurately align with the cutting tool, which in turn causes the cutting surface to be tilted and the dimensional deviation to be too large. Subsequent processing requires additional grinding, which increases the processing steps and production costs. Summary of the Invention

Specifically, the operation of the third motor 26 can drive the fourth bevel gear 25 to rotate, and simultaneously, through the meshing of the fourth bevel gear 25 and the third bevel gear 23, it drives the third bevel gear 23 to rotate. The rotation of the third bevel gear 23... During the process, the spline rod 22 and the second bevel gear 20 can be rotated by the cooperation of the spline opening 24 and the spline rod 22. Then, the first bevel gear 19 and the guide wheel 10 can be rotated by the meshing of the second bevel gear 20 and the first bevel gear 19. The friction between the guide wheel 10 and the blank drives the blank to move and feed it to the cutting station.

Simultaneously, the meshing of the first gear 17 with the first gear ring 16 drives the first gear ring 16 and the adjusting ring 13 to rotate. During the rotation of the adjusting ring 13, the cooperation between the adjusting through hole 14 and the guide post 15 moves multiple guide blocks 9, thereby causing the guide wheel 10 to press against the surface of the blank to achieve blank positioning. Then, the operator controls the third motor 26 to operate, which drives the fourth bevel gear 25 to rotate. Simultaneously, the meshing of the fourth bevel gear 25 with the third bevel gear 23 drives the third bevel gear 23 to rotate. During the rotation of the third bevel gear 23, the spline opening 24 and the spline rod 22... The spline rod 22 and the second bevel gear 20 are rotated in conjunction with each other. The meshing of the second bevel gear 20 with the first bevel gear 19 drives the first bevel gear 19 and the guide wheel 10 to rotate. The friction between the guide wheel 10 and the blank drives the blank to move and feed it to the cutting station. During the feeding process, the guide wheel 10 can be used to position the blank axially. At the same time, the rotation and stopping of the guide wheel 10 can be used to position the blank radially, thereby improving the cutting accuracy. When the blank is moved to the cutting position below the cutting wheel 6, the operator controls the first motor 7 and the hydraulic rod 8 to work. The operation of the first motor 7 can drive the cutting wheel 6 to rotate, and the operation of the hydraulic rod 8 can drive the protective cover 5 and the cutting wheel to move, thereby facilitating the cutting of the blank by the cutting wheel.
