Description
Technical Field
[0001] The invention belongs to the technical field of bearing processing, and in particular relates to a surface grinding device for bearing processing. Background Art
[0002] With the rapid development of the manufacturing industry, bearings are important components in mechanical transmission systems. Their processing accuracy and surface quality have a vital impact on the overall performance and life of mechanical equipment. In the bearing processing process, surface grinding is a key step to ensure the surface finish and flatness of the bearing. Traditional bearing surface grinding equipment mostly uses hydraulic or pneumatic clamping systems. Although such systems meet the needs of bearing clamping to a certain extent, there are still many deficiencies in practical applications.
[0003] From the perspective of technological development, hydraulic and pneumatic clamping systems have been widely used in the field of bearing processing due to their simple structure and easy operation. However, such systems often have delay problems during the clamping process, that is, the clamping force responds slowly, making it difficult to quickly and accurately position the bearing. This delay not only affects the machining accuracy of the bearing, but may also cause the bearing to move during high-speed grinding, further reducing the quality of surface grinding. In addition, hydraulic and pneumatic systems usually need to be equipped with complex pipelines and valves, which not only increases the maintenance cost of the equipment, but also limits the application flexibility of the equipment in a small space, so staff need to improve them.

[0035] When in use, the mounting platform 1 is used as the basic supporting structure, the mounting rod 2 is laterally fixed above the mounting platform 1, and its two ends form a rigid connection frame through the assembly disk 3. The control rod 4 is fixedly connected to one of the assembly disks 3, and a servo motor 5 is integrated inside. Its output end drives the driving rod 6 that passes through the mounting rod 2 and the assembly disk 3 to rotate. The first driving gear 7 is fixed in the middle of the driving rod 6, and the first threaded rod 9 is driven to rotate synchronously by meshing multiple groups of first transmission gears 8, so that the threaded sleeve 10 moves axially along the inner wall of the positioning tube 13, thereby pushing the top extrusion plate 11 to perform a clamping or loosening action, and the bottom limit block 12 ensures the linearity of the moving trajectory of the threaded sleeve 10.

[0036] Embodiment 2:
[0037] See also Figures 1 to 7 As shown, a control frame 19 is fixedly connected to the top of the mounting platform 1, a first drive motor 20 is fixedly connected to the inner wall of the control frame 19, and the output end of the first drive motor 20 is installed at the tail end of the control rod 4, a bearing frame 21 is fixedly connected to the surface of the control rod 4, an electric telescopic rod 22 is fixedly connected to the surface of the bearing frame 21, an additional plate 23 is installed at the output end of the electric telescopic rod 22, and two cleaning brushes 24 are rotatably connected to the inner wall of the additional plate 23.
[0038] When in use, it is fixed to the top of the mounting platform 1 through the control frame 19, and the first drive motor 20 is integrated inside. The motor directly drives the control rod 4 to rotate, thereby linking the entire clamping system. The bearing frame 21 arranged on the surface of the control rod 4 provides radial support, and the electric telescopic rod 22 installed thereon can accurately adjust the axial position of the mounting plate 23. The mounting plate 23 has two built-in high-speed rotating cleaning brushes 24, which can simultaneously clean the bearing surface online during the grinding process. This combined structure realizes the coordination of three major functions: the first drive motor 20 provides a power source for the clamping system through the control rod 4; the travel control of the electric telescopic rod 22 The system ensures that the cleaning brush 24 always maintains the best contact pressure with the bearing surface; the rotating brush can promptly remove the metal debris generated by grinding to avoid secondary scratches on the processed surface. In particular, the bearing frame 21 adopts an angular contact ball bearing design, which not only bears the radial load of the control rod 4, but also allows the electric telescopic rod 22 to perform axial fine adjustment. Its structural rigidity is increased by more than 40% compared with the traditional cantilever installation. The nylon brush filaments of the cleaning brush 24 are doped with silicon carbide particles, which produce an auxiliary polishing effect while cleaning, reducing the surface roughness Ra value of the bearing by about 15%, forming an automated processing unit integrating clamping, grinding and cleaning.
[0039] Embodiment three:
[0040] See also Figures 1 to 7 As shown, the top of the mounting platform 1 is fixedly connected with an electric guide rail 25, the inner wall of the electric guide rail 25 is slidably connected with a grinding frame 26, the surface of the grinding frame 26 is fixedly connected with a protective frame 27, the inner wall of the protective frame 27 is fixedly connected with a second drive motor 28, a rotating rod 29 is installed at the output end of the second drive motor 28, the front end of the rotating rod 29 is fixedly connected with a control rod 30, the surface of the control rod 30 is fixedly connected with multiple groups of mounting tubes 31, the inner wall of the mounting tube 31 is fixedly connected with an electrical connector 32, the top of the electrical connector 32 is electrically connected with an iron core 33, the top of the mounting tube 31 is plugged with a fixing rod 34, the bottom end of the fixing rod 34 is fixedly connected with a negative magnetic block 35, and the bottom of the negative magnetic block 35 is adsorbed and connected to the top of the iron core 33, the top of the fixing rod 34 is fixedly connected with a grinding plate 36, and the top of the mounting platform 1 is fixedly connected with a control panel 37.
[0041] When in use, it is installed on the top of the installation platform 1 through the electric guide rail 25, and the grinding frame 26 thereon can move precisely along the guide rail to realize feed control. A protective frame 27 is provided on the outside of the grinding frame 26, and a second drive motor 28 is integrated inside. The motor drives the control rod 30 to rotate through the rotating rod 29. A plurality of mounting tubes 31 are distributed on the control rod 30, and each mounting tube 31 has a built-in electrical connector 32 and an iron core 33. When the electrical connector 32 is energized, the iron core 33 forms a positive magnetic block, which generates strong magnetic adsorption with the negative magnetic block 35 at the bottom of the fixed rod 34, thereby fixing the grinding plate 36; after power failure, the magnetism disappears, and the grinding plate can be quickly replaced. This structure has three innovative features: first, a modular magnetic design is adopted, so that the grinding plate 36 can be disassembled independently in different areas, which is convenient for local replacement of the wear area; second, the on-off combination of each electrical connector 32 can be programmably controlled through the control panel 37, so as to realize the rapid configuration of grinding plates of different specifications; third, the protective frame 27 adopts a double-layer sound insulation structure to reduce the grinding noise to below 75 decibels. In particular, the negative pole magnetic block 35 uses a neodymium iron boron permanent magnet, which can generate an adsorption force of more than 12N when combined with the electromagnet core 33 to ensure stability during high-speed grinding. The grinding plate 36 is designed in 60° sector-shaped partitions, and each sector-shaped area can be disassembled and assembled separately. When local wear occurs, only the corresponding block needs to be replaced, which extends the service life of the traditional integral grinding plate by 3 times. The system can achieve a feed accuracy of ±0.02mm through the closed-loop control of the electric guide rail 25, and with the programmable magnetic suction replacement system, the equipment can adapt to multi-process processing requirements from rough grinding to fine polishing.
[0042] Embodiment 4:
[0043] See also Figures 1 to 7 As shown in the figure, in the mass production of automobile hub bearings, the outer ring surface of the bearing needs to go through multiple processes such as rough grinding, fine grinding, and polishing. Traditional equipment has the following problems: the clamping mechanism has low efficiency in changing models and is difficult to adapt to the rapid switching of bearings of different specifications; the grinding plate needs to be replaced as a whole after wear, which is costly; grinding debris can easily scratch the processed surface, affecting the yield.
[0044] The operator places the wheel hub bearing to be processed on the mounting platform 1 and selects a processing program of corresponding specifications through the control panel 37 .
[0045] The first driving motor 20 drives the control rod 4 to rotate, and the linkage driving rod 6 drives the first driving gear 7 and the second driving gear 14 to rotate synchronously.
[0046] The first transmission gear 8 drives the first threaded rod 9 to push the threaded sleeve 10, so that the extrusion plate 11 clamps the outer ring of the bearing radially, and the limit block 12 ensures the clamping straightness.
[0047] Axial limit: The second transmission gear 15 drives the second threaded rod 17 through the connecting rod 16, so that the positioning sleeve rod 18 presses the bearing end surface from both ends to prevent axial displacement.
[0048] The electric telescopic rod 22 adjusts the position of the mounting plate 23 so that the cleaning brush 24 is close to the bearing surface. The brush rotates at high speed (2000rpm) to remove the oxide layer and debris, and the silicon carbide particles are polished synchronously.
[0049] The electric guide rail 25 drives the grinding frame 26 to move to the processing position, and the second driving motor 28 drives the control rod 30 to rotate through the rotating rod 29.
[0050] Modular grinding: After the electrical connector 32 is powered on, the iron core 33 and the negative magnetic block 35 adsorb and fix the sector-shaped grinding plate 36. According to the wear condition, only a local block is replaced, such as replacing two 60° sector-shaped plates, and the rest of the area continues to be used.
[0051] Rough grinding stage: the control panel 37 selects the high-hardness grinding plate 36, which is fixed by magnetic attraction and the excess is removed at a feed rate of 0.1 mm / time.
[0052] Fine polishing stage: Switch to the fine-grained grinding plate, the electric guide rail 25 feeds with an accuracy of ±0.02mm, and cooperates with the synchronous polishing of the cleaning brush 24, and the final surface roughness reaches Ra0.2μm.
[0053] Working principle: The mounting platform serves as the basic supporting structure of the equipment. The mounting rod is transversely fixed above the mounting platform. Its two ends form a rigid frame through the assembly disk. The control rod is fixedly connected to one of the assembly disks. The internal integrated servo motor drives the drive rod that runs through the mounting rod and the assembly disk to rotate. The first drive gear fixed in the middle of the drive rod drives the first threaded rod to rotate synchronously by engaging multiple sets of first transmission gears, so that the threaded sleeve moves axially along the inner wall of the positioning tube, pushing the top extrusion plate to perform radial clamping action. At the same time, the bottom limit block ensures the linearity of the moving trajectory of the threaded sleeve. The second drive gears on both sides of the drive rod drive the second threaded rod to rotate through the second transmission gear and the connecting rod, so that the positioning sleeve rod can be axially extended and retracted in the assembly disk. For the two-way limit of the bearing end face, the first drive motor in the control frame provides power source for the entire clamping system by driving the control rod. The bearing frame adopts angular contact ball bearing design to support the control rod. The electric telescopic rod on it accurately adjusts the position of the installation plate to keep the cleaning brush at the best contact pressure. The grinding frame realizes precise feeding through the electric guide rail. The internal second drive motor drives the control rod to rotate through the rotating rod. The electrical appliance in the installation tube is energized to make the iron core generate magnetism and adsorb the negative magnetic block at the bottom of the fixed rod to fix the grinding plate. It can be quickly replaced when the power is off. The protective frame adopts a double-layer sound insulation structure to reduce noise. The control panel centrally controls the coordinated work of various modules, and finally realizes the full process of automated processing from bearing positioning and clamping, surface cleaning to multi-stage grinding.
[0054] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
