Description

Technical Field

[0001] This utility model relates to the field of bearing processing technology, specifically a bearing edge grinding machine for metallurgical bearing processing. Background Technology

[0002] The flange of a metallurgical bearing is a ring-shaped component located on the inner or outer ring of the bearing. It is used to restrict the axial movement of the shaft or internal parts of the bearing, increase the axial positioning and stability of the bearing. The flange of a metallurgical bearing usually needs to be ground during processing. Grinding can make the flange surface smoother, reduce surface roughness, reduce friction with rolling elements and other components, improve the rotational accuracy and efficiency of the bearing, and reduce energy loss.

[0003] Utility model patent CN221936244U discloses a bearing flange grinding device for bearing processing, including a support assembly comprising a worktable and a support column fixed to the lower surface of the worktable; a rotating assembly disposed on the upper surface of the support assembly; the rotating assembly comprising a fixed plate fixed to the upper surface of the worktable and a rotating shaft rotatably connected to one side of the fixed plate; and a moving assembly disposed on one side of the rotating assembly; the moving assembly comprising a rotating plate fixed to one side of the rotating shaft and a limiting plate movably connected to one side of the rotating plate. This utility model, by setting up the rotating assembly and the moving assembly, solves the problem that when grinding the outer ring of a bearing flange, manual grinding of the bearing flange requires manual rotation of the bearing flange, which is time-consuming, labor-intensive, and inefficient.

[0004] However, the above-mentioned existing technical solutions still have the following shortcomings: when the device clamps and fixes the bearing baffle, it requires four motors to drive the threaded rods to rotate synchronously so that the limiting plate can clamp and position the inner ring of the baffle. The cost of setting up four motors is high, and the synchronous control of four motors is relatively complicated. A precise synchronization system is required to ensure that the four threaded rods rotate by the same amount at the same time. Otherwise, it may lead to clamping imbalance or even damage to the bearing. Utility Model Content

[0005] In view of the shortcomings of the prior art, the purpose of this utility model is to provide a bearing flange grinding machine for metallurgical bearing processing, so as to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a bearing flange grinding machine for metallurgical bearing processing, comprising a grinding mechanism, a positioning mechanism provided on one side of the grinding mechanism, and a driving mechanism provided on the surface of the positioning mechanism;

[0014] Compared with the prior art, the beneficial effects achieved by this utility model are:

[0015] First, this utility model significantly improves the processing efficiency and precision of metallurgical bearing flanges by integrating a positioning mechanism, a driving mechanism, and a grinding mechanism. The positioning mechanism adopts a design where a single cylinder drives multiple sets of linkage plates and arc-shaped clamping plates, ensuring uniform distribution of clamping force and avoiding workpiece offset or deformation caused by synchronization errors in traditional multi-motor systems. The buffer spring further optimizes the clamping process, absorbing mechanical impact and protecting the integrity of the workpiece surface. The driving mechanism achieves smooth rotation of the turntable through the meshing transmission of gears and gear rings.

[0023] The specific embodiments of this utility model will now be described in further detail with reference to the accompanying drawings.

[0024] Please see Figure 1-5 A bearing edge grinding machine for metallurgical bearing processing includes a grinding mechanism 1, a positioning mechanism 2 on one side of the grinding mechanism 1, and a driving mechanism 3 on the surface of the positioning mechanism 2.

[0025] The positioning mechanism 2 includes a mounting plate 201. A circular guide rail 202 is fixed on the left side surface of the mounting plate 201. Multiple sliders 203 are slidably connected to the surface of the circular guide rail 202. A turntable 204 is fixed to the surface of the multiple sliders 203. A through groove 205 is opened on the surface of the mounting plate 201. An extension frame 206 is fixed to the surface of the turntable 204. A positioning cylinder 207 is fixed to the surface of the extension frame 206. One end of the positioning cylinder 207 passes through the extension frame 206 and is fixed with a guide rod 208. The surface of the guide rod 208 slidably passes through the turntable 204. Three U-shaped blocks 209 are fixed to the left side surface of the turntable 204. A push plate 210 is hinged to the surface of the U-shaped blocks 209. Three linkage plates 211 are hinged to the surface of the guide rod 208. The linkage plates 211 are hinged to the push plates 210. An arc-shaped clamping plate 212 is fixed to the surface of the push plate 210.

[0026] Through the above technical solution, the positioning mechanism 2 fixes the circular guide rail 202 through the mounting plate 201, and the turntable 204 is slidably connected to the circular guide rail 202 through the slider 203; the positioning cylinder 207 pushes the guide rod 208 to move axially, and the guide rod 208 drives the three push plates 210 to rotate around the hinge point of the U-shaped block 209 through the linkage plate 211, which drives the arc-shaped clamping plate 212 to expand outward synchronously, so as to achieve uniform clamping of the inner ring of the flange. Through this single positioning cylinder 207 driving multiple sets of linkage structures, the synchronicity and symmetry of the clamping action are ensured, and the synchronous adjustment error of multiple motors is avoided; the arc-shaped clamping plate 212 has a high degree of fit with the inner ring of the flange, reducing the risk of workpiece deformation; the mechanical linkage design reduces the dependence on multiple power sources and simplifies the control system.

[0027] The grinding mechanism 1 includes a mounting frame 101. A movable frame 102 is provided on the right side of the mounting frame 101. Two first linear guide rails 103 are fixed on the top of the movable frame 102. A mounting platform 104 is slidably connected to the surface of the first linear guide rails 103. A drive motor 105 is fixed on the top of the mounting platform 104. A sliding groove 106 is provided on the top of the movable frame 102. The output shaft of the drive motor 105 passes through the mounting platform 104 and is fixed with a connecting shaft 107. The bottom of the connecting shaft 107 passes through the sliding groove 106 and is fitted with a grinding block 108. A controller 4 is fixed on the surface of the mounting frame 101.

[0028] Through the above technical solution, the mounting frame 101 supports the movable frame 102, and the first linear guide rail 103 guides the mounting platform 104 to move laterally; the first linear guide rail 103 improves the lateral movement accuracy of the grinding block 108 and avoids uneven wear, the drive motor 105 drives the grinding block 108 to rotate through the connecting shaft 107, and the slide groove 106 allows the grinding block 108 to adjust its position so that the grinding block 108 can perform grinding treatment on the surface of the positioned bearing baffle.

[0029] The drive mechanism 3 includes a geared motor 301, which is fixed to one side of the surface of the mounting plate 201. The output shaft of the geared motor 301 passes through the mounting plate 201 and is fixed with a gear 302. A gear ring 303 meshes with the surface of the gear 302 and is fixed to the surface of the turntable 204.

[0030] Through the above technical solution, the gear motor 301 drives the gear 302 to rotate, and the gear 302 meshes with the gear ring 303 to drive the turntable 204 to rotate along the circular guide rail 202, so that the clamped edge rotates synchronously with the turntable 204, and completes circumferential processing in conjunction with the grinding block 108.

[0031] A mounting block 213 is fixed to the surface of the guide rod 208, and a buffer spring 214 is fixed to the right side of the surface of the turntable 204. One end of the buffer spring 214 is fixedly connected to the surface of the mounting block 213.

[0032] Through the above technical solution, when the guide rod 208 moves, the mounting block 213 compresses or releases the buffer spring 214. The deformation of the buffer spring 214 absorbs the impact force of the positioning cylinder 207, balances the instantaneous pressure fluctuation during the movement of the guide rod 208, and extends the life of the positioning cylinder 207 and the guide rod 208. Dynamic pressure compensation avoids excessive clamping that could cause workpiece deformation and improves clamping safety.

[0033] A propulsion cylinder 109 is fixed on the top left side of the movable frame 102, and one end of the propulsion cylinder 109 is fixedly connected to the left side surface of the mounting platform 104.

[0034] Through the above technical solution, the propulsion cylinder 109 is fixed on the left side of the movable frame 102, and its piston rod is connected to the mounting platform 104. The mounting platform 104 is driven by air pressure to move laterally along the first linear guide rail 103, adjusting the contact position between the grinding block 108 and the edge, so as to achieve the contact effect between the edge and the grinding block 108 after installation.

[0035] A lifting cylinder 110 is fixed to the lower right side surface of the mounting bracket 101, and the top of the lifting cylinder 110 is fixedly connected to the lower surface of the movable bracket 102.

[0036] With the above technical solution, the lifting cylinder 110 is fixed on the lower right side of the mounting frame 101, and its piston rod is connected to the movable frame 102. The movable frame 102 is driven by air pressure to rise and fall vertically along the second linear guide rail 111, adjusting the height of the grinding block 108 so that the grinding block 108 can more comprehensively grind the edge surface.

[0037] Two second linear guide rails 111 are fixed on one side of the mounting bracket 101. A connecting plate 112 is slidably connected to the surface of the second linear guide rails 111. The connecting plate 112 is fixedly connected to the left side of the movable bracket 102.

[0038] Through the above technical solution, the second linear guide rail 111 restricts the movable frame 102 to move only in the vertical direction, avoiding lateral deviation.

[0039] Working principle: The bearing retaining edge is placed on the left surface of the turntable 204. The positioning cylinder 207 of the positioning mechanism 2 is activated. The piston rod of the positioning cylinder 207 pushes the guide rod 208 to move to the left. The guide rod 208 drives the three push plates 210 to rotate outward around the hinge point of the U-shaped block 209 through the hinged linkage plate 211, so that the arc-shaped clamping plate 212 expands synchronously and fits tightly against the inner ring of the retaining edge, completing the clamping and fixing. The buffer spring 214 absorbs the impact force during the movement of the guide rod 208 to prevent clamping overload. Then, the reduction motor 301 of the drive mechanism 3 is started. Through the meshing transmission of the gear 302 and the gear ring 303, the turntable 204 is driven to rotate at a constant speed along the circular guide rail 202, which drives the clamped retaining edge to rotate synchronously. At the same time, the drive motor 1 of the grinding mechanism 1... 05 Start, driving the grinding block 108 at the end of the connecting shaft 107 to rotate at high speed; the lifting cylinder 110 pushes the movable frame 102 to rise and fall vertically along the second linear guide rail 111, adjusting the radial contact position between the grinding block 108 and the edge; the push cylinder 109 drives the mounting table 104 to move laterally along the first linear guide rail 103, controlling the feed depth of the grinding block 108; the controller 4 coordinates the action parameters of the reduction motor 301, drive motor 105, lifting cylinder 110 and push cylinder 109, so that the rotation speed of the turntable 204, the rotation speed of the grinding block 108 and the feed amount are matched, so as to achieve uniform grinding of the outer ring of the edge in the full circumference. After completing a single processing, the positioning cylinder 207 resets, the arc-shaped clamp 212 retracts to release the workpiece, and enters the next cycle.
