Description

Technical Field

[0001] The utility model relates to the technical field of bearing needle rollers, in particular to a surface rough polishing device for bearing needle rollers. Background Art

[0002] Bearing needle rollers refer to rolling elements used to support the inner and outer rings of bearings. They are characterized by being thin and long. Their main function is to bear and transmit loads when the bearing is running, reduce friction, and ensure the smooth operation of the bearing. Bearing needle rollers need to be ground during the processing process, including coarse grinding and fine grinding. However, existing grinding and polishing barrels usually pour the material directly into the polishing machine for a one-time polishing, and then clean it. The grinding and polishing barrel grinds and polishes the workpiece through the collision and friction generated by the relative movement between the grinding medium and the workpiece. The grinding and polishing efficiency is low and usually takes several hours. In addition, a large amount of dust and waste chips are generated during the polishing process and will be adsorbed on the surface of the workpiece. Cleaning also takes several hours. At the same time, the friction and collision generated by the relative movement between the grinding medium and the workpiece in the grinding and polishing barrel will cause certain wear on the bearing needle roller body, affecting production quality. For example, Chinese patent CN117620877A discloses a bearing needle roller grinding and polishing barrel, comprising a grinding box, a support plate, a first fixed plate, a second fixed plate, a cleaning mechanism, and a chip suction mechanism. The bottom of the support plate is fixedly connected to a base, the right side of the base is fixedly connected to a Z-shaped plate, and the top of the Z-shaped plate is provided with a chip suction mechanism. The chip suction mechanism includes a chip suction box, which is fixedly connected to the top of the Z-shaped plate. The first and second fixed plates are fixedly connected to the front and rear sides of the top of the support plate, respectively. The cleaning mechanism includes a water tank and a first rotating motor. The grinding and polishing barrel, through the provision of the polishing mechanism, can increase the friction between the workpiece and the grinding medium, thereby improving its polishing quality. The provision of the cleaning mechanism can clean the polished workpiece, reducing the number of steps. The provision of the chip suction mechanism can also play a chip suction role, preventing waste chips from being adsorbed on the surface of the polished workpiece, further reducing cleaning time. This patent has made some improvements to the efficiency of the surface polishing of the bearing needle roller, but it still requires a lot of time, and the centralized processing of a large number of bearing needle rollers cannot guarantee the surface quality of the bearing needle rollers.

[0003] Therefore, it is necessary for those skilled in the art to provide a surface rough polishing device for bearing needle rollers to improve the efficiency and quality of surface treatment of bearing needle rollers. Utility Model Content

[0022] The present invention will now be described in detail with reference to the accompanying drawings. This drawing is a simplified schematic diagram, which only illustrates the basic structure of the present invention in a schematic manner, and therefore only shows the components related to the present invention.

[0023] See also Figure 1 、 Figure 2 The present invention provides a rough polishing device for a bearing needle roller, comprising a frame 10, a telescopic cylinder 11 and a polishing cylinder 20 disposed on the frame 10. The polishing cylinders 20 are provided in plurality and coaxially arranged on the frame 10. The polishing cylinders 20 abut and communicate with each other, and the telescopic rod of the telescopic cylinder 11 is slidably disposed within the polishing cylinder 20. Preferably, the telescopic cylinder 11 is a pneumatic cylinder. The bearing needle roller is slidably disposed within the polishing cylinder 20, with the telescopic rod of the telescopic cylinder 11 abutting against the bearing needle roller.

[0024] During use, the telescopic rod of the telescopic cylinder 11 is used to abut the bearing needle roller, so that the bearing needle roller slides and is polished in multiple polishing cylinders 20, thereby realizing surface treatment processes such as grinding and polishing of the bearing needle roller, and removing impurities, burrs and other defects on its surface. Compared with the prior art of cleaning a large number of the bearing needle rollers at the same time, the utility model can realize the surface treatment of each of the bearing needle rollers in turn, and the product quality is higher and the effect is better.

[0025] Furthermore, a vibration loader 12 is provided on the frame 10, and the bearing needle roller is placed in the vibration loader 12. The discharge pipe of the vibration loader 12 is connected to the grinding cylinder 20 close to the telescopic cylinder 11 for loading the bearing needle roller into the grinding cylinder 20.

[0026] The vibration feeder 12 is a common vibration feeder on the market, which is used to arrange the bearing needle rollers neatly and evenly feed them, so as to load the bearing needle rollers into the grinding cylinder 20 one by one.

[0027] See also Figure 3 、 Figure 4 A discharge port 13 is provided on the grinding cylinder 20 near the telescopic cylinder 11. The discharge port 13 passes through the wall of the grinding cylinder 20. The discharge pipe of the vibration loader 12 is detachably connected to the discharge port 13 and is interconnected. The grinding cylinder 20 has a cylindrical tubular structure. The inner wall diameter of the grinding cylinder 20 is consistent with the diameter of the bearing needle roller. At the same time, the diameter of the telescopic rod of the telescopic cylinder 11 is smaller than the diameter of the bearing needle roller.

[0028] During use, the bearing needle roller passes through the discharge port 13 from the discharge tube of the vibrating loader 12 and falls into the grinding cylinder 20. When one bearing needle roller falls into the grinding cylinder 20 from the discharge port 13, the adjacent bearing needle roller is located in the discharge port 13. When the telescopic rod of the telescopic cylinder 11 pushes the bearing needle roller located in the grinding cylinder 20 away and resets it, the bearing needle roller located at the discharge port 13 falls into the grinding cylinder 20, completing the feeding cycle. The present utility model utilizes the telescopic rod of the telescopic cylinder 11 to push only one bearing needle roller at a time within the grinding cylinder 20, thereby ensuring processing stability and orderly feeding, and preventing problems such as material jamming.

[0029] See also Figure 5 、 Figure 6 and Figure 7 The grinding cylinder 20 is provided with a fixed ring 21 and a disassembly ring 22, and the grinding cylinder 20 is clamped and connected between the fixed ring 21 and the disassembly ring 22.

At the same time, the disassembly ring 22 is detachably connected to the fixed ring 21 using fasteners such as bolts or screws.

[0030] During use, first install the retaining ring 21 onto the connecting block 25, then install the grinding cylinder 20 onto the retaining ring 21. Install the disassembly ring 22, and connect the grinding cylinder 20 between the retaining ring 21 and the disassembly ring 22. Ensure that the multiple grinding cylinders 20 are coaxially arranged and interconnected, completing the installation. Multiple grinding cylinders 20 can be provided, and the removable disassembly ring 22 allows the operator to quickly replace the grinding cylinder 20, ensuring optimal grinding results.

[0031] Furthermore, the inner wall of the grinding cylinder 20 is provided with a spiral convex wall 23, which is arranged in a spiral pattern around the axis of the grinding cylinder 20. The bearing needle roller is coupled to the spiral convex wall 23 and is movable along the axis of the grinding cylinder 20. The bearing needle roller is also rotatable within the spiral convex wall 23. During use, when the telescopic rod of the telescopic cylinder 11 pushes the bearing needle roller to move within the grinding cylinder 20, the bearing needle roller rotates around the spiral convex wall 23 and moves along the axis of the grinding cylinder 20. This achieves comprehensive grinding of the bearing needle roller surface, improving the comprehensiveness and polishing effect.

[0032] Furthermore, a chip groove 24 is provided on the outer wall of the grinding cylinder 20. The chip groove 24 passes through the wall of the grinding cylinder 20 along the axis of the grinding cylinder 20. The chip groove 24 is located below the grinding cylinder 20 and faces the upper plane of the frame 10, thereby achieving rapid discharge of grinding waste chips and ensuring processing stability.

[0033] The specific operation method of the present invention is as follows: Step 1: first install the fixing ring 21 on the connecting block 25, then install the grinding cylinder 20 on the fixing ring 21, install the disassembly ring 22, so that the grinding cylinder 20 is connected between the fixing ring 21 and the disassembly ring 22, and at the same time, the telescopic rod of the telescopic cylinder 11 is extended into the grinding cylinder 20 to complete the installation.

[0034] Step 2: Start the loader 12, the bearing needle roller falls into the grinding cylinder 20, start the telescopic cylinder 11, the telescopic rod of the telescopic cylinder 11 pushes the bearing needle roller to move in the grinding cylinder 20, and the grinding is completed.

[0035] The utility model utilizes the telescopic rod of the telescopic cylinder 11 to abut against the bearing needle roller, so that the bearing needle roller slides and is polished in multiple polishing cylinders 20, thereby realizing surface treatment processes such as grinding and polishing of the bearing needle roller, and removing impurities, burrs and other defects on its surface. Compared with the prior art of cleaning a large number of the bearing needle rollers at the same time, the utility model can realize surface treatment of each of the bearing needle rollers in turn, resulting in higher product quality and better effect.
