Description

Technical Field

[0001] This utility model relates to the field of bearing processing technology, specifically to a fine grinding device for the ball base surface of bearing rolling elements. Background Technology

[0002] In modern mechanical industry, bearings, as key basic components, are widely used in various mechanical equipment. Their performance directly affects the overall operating accuracy, stability, and service life of the equipment. As the core component of a bearing, the machining quality of its spherical base surface is of paramount importance.

[0003] Traditional grinding processes for the spherical base surfaces of bearing rolling elements typically employ a single-station, single-grinding-head method. In this approach, completing the grinding of each rolling element's spherical base surface requires a series of steps, including workpiece clamping, grinding, and workpiece disassembly, before the next workpiece can be processed. This process results in a significant amount of time being wasted on non-grinding auxiliary operations, leading to low production efficiency and difficulty in meeting the ever-increasing demands of industrial production. Furthermore, traditional equipment often requires complex procedures and lengthy downtime for grinding head replacement and maintenance, further impacting production efficiency and overall equipment utilization. It is inconvenient to use and causes considerable inconvenience. Therefore, to address these shortcomings, a fine grinding device for the spherical base surfaces of bearing rolling elements is proposed to improve upon these limitations. Utility Model Content

[0004] The purpose of this invention is to provide a fine grinding device for the ball base surface of bearing rolling elements to solve the problems mentioned in the background art.

[0017] As a preferred embodiment, furthermore, cylinders 9 are screwed to both the left and right ends of the front side of the inner cavity of the workbench 1. A second base 10 is installed at the rear output end of the cylinder 9. One end of a second support rod 11 is installed at the center of the top of the second base 10. The other end of the second support rod 11 extends out of the upper surface of the workbench 1 and is equipped with a second bracket 12. Bases 13 are provided on both the front and rear sides of the second bracket 12. One end of a connecting seat 14 is inserted into the inner cavity of the base 13. The other end of the connecting seat 14 extends out of the inner cavity of the base 13. The outer wall of the base 13 is equipped with a grinding head 15. The outer wall of the connecting seat 14 is provided with a fixing hole 16. The front and rear sides of the top of the inner cavity of the base 13 are equipped with one end of a spring 17, and the other end of the spring 17 is equipped with a pad 18. The center of the top of the pad 18 is equipped with one end of a pull rod 19. The other end of the pull rod 19 passes through the spring 17 and extends out of the top of the base 13. The center of the bottom of the pad 18 is equipped with a fixing block 20. The bottom end of the fixing block 20 is inserted into the inner cavity of the fixing hole 16.

[0018] As a preferred embodiment, the fixing block 20 and the fixing hole 16 are matched and their positions correspond.

[0019] As a preferred option, the centers of the grinding head 15 and the clamping plate 7 are both at the same horizontal level.

[0020] As a preferred option, the number of first supports 6 is four, and the two first supports 6 on the left and right are grouped together, with the two groups of first supports 6 distributed on the front and rear sides of the second support 12 respectively.

[0021] All electrical components mentioned in this solution are existing technologies, and their models are only one of them. Any electrical component that meets the requirements of this solution can be used.

[0022] Those skilled in the art should connect all electrical components and their compatible power supplies in this case via wires, and should select appropriate controllers according to actual conditions to meet control requirements. The specific connection and control sequence should refer to the working principle described below, where the electrical components are connected in sequence. The detailed connection methods are well-known in the art. The following mainly introduces the working principle and process, without further explanation of electrical control. The specific work is as follows.

[0023] In use, the workpiece to be processed is placed at the center of the inner side of the front and rear clamping plates 7 respectively. The first motor 2 is turned on, driving the screw 3 to rotate. The rotating screw 3 causes the two first bases 4, threaded onto its outer wall, to move together with the first support rod 5, the first bracket 6, and all structural components on the first bracket 6, either inward or outward. When the two clamping plates 7 move inward and abut against both ends of the workpiece, they can clamp and fix the workpiece. The second motor 8 is turned on, driving the clamping plates 7 and the workpiece to rotate together. The cylinder 9 is turned on, driving the second base 10, the second support rod 11, the second bracket 12, and all structural components on the second bracket 12 to move forward or backward. At this time, when the front and rear grinding heads 15 contact the front and rear rotating workpieces respectively, they can perform grinding processing on the outer surface. That is, after the workpiece on the front side is ground, the second support rod 11, the second bracket 12, and all structural components on the second bracket 12 move forward or backward. The frame 12 moves the grinding head 15 backward to grind the workpiece on the rear side. At the same time, the operator can disassemble and replace the workpiece that has been ground on the front side. By grinding the two workpieces at intervals, continuous processing can be achieved. When it is necessary to disassemble or assemble the grinding head 15, simply pull the pull rod 19 upward. The pull rod 19 will move the pad 18 and the fixing block 20 upward together and squeeze the spring 17. When the fixing block 20 is completely removed from the inner cavity of the fixing hole 16, the operator can directly remove or insert the connecting seat 14 from the inner cavity of the base 13, thus completing the disassembly and assembly of the grinding head 15. This device adopts a dual-station design. By processing the workpieces at the two stations at intervals, the time for changing parts is saved, thereby achieving continuous grinding processing and significantly improving production efficiency. In addition, it adopts a snap-fit ​​method, which can quickly disassemble and assemble the grinding head 15, making it easy to replace and maintain. It is convenient to use, highly practical, and suitable for promotion.
