Abstract
Description
Technical Field
[0001] This utility model relates to the field of spherical bearing manufacturing, specifically to a grinding device for spherical bearing manufacturing. Background Technology
[0002] Spherical plain bearings are a special type of bearing primarily used to withstand multi-directional loads and can tolerate a relatively large angular deviation between the shaft and the bearing housing. Spherical plain bearings consist of an outer ring and an inner ring, which are in spherical contact. During rotation, the end face of the inner ring rotates into the outer ring, and its end face also needs a smooth surface; therefore, the upper and lower end faces of the inner ring need to be ground during the manufacturing process.
[0003] Existing grinding devices require constant replacement of fine abrasives when grinding the upper and lower end faces of the inner ring. This abrasive replacement delays the process and reduces production efficiency. Therefore, those skilled in the art have provided a grinding device for manufacturing spherical plain bearings to solve the problems mentioned in the background section. Utility Model Content

[0018] Please see Figures 1-5 This embodiment provides a grinding device for producing spherical bearings, including a worktable 1, a rotating seat 3 rotatably connected above the worktable 1, a clamping mechanism 4 installed above the rotating seat 3, the clamping mechanism 4 including a fixed frame 41, the fixed frame 41 being fixedly installed on the rotating seat 3, a plurality of extension rods 42 being slidably connected above the fixed frame 41, an extension block 43 being fixedly connected to the outer side of the upper end of the extension rod 42, a moving rod 44 being fixedly connected below the extension rod 42, the lower end of the moving rod 44 passing through the fixed frame 41, a telescopic rod 45 being installed inside the fixed frame 41, a conical seat 46 being fixedly connected to the upper end of the telescopic rod 45, and the conical seat 46 being located between the moving rods 44; A fixed seat 5 is fixedly connected above the workbench 1 on one side of the rotating seat 3. A replacement mechanism 6 is rotatably connected above the fixed seat 5. The replacement mechanism 6 includes a rotating disk 61, which is inserted into the fixed seat 5 and rotatably connected to it. A mounting seat 62 is fixedly connected above the rotating disk 61. Multiple lifting platforms 65 are fixedly connected around the mounting seat 62. An abrasive seat 66 is fixedly connected above each lifting platform 65. A fixed rod 67 is fixedly connected above the abrasive seat 66. A movable rod 68 is slidably connected to the outside of the fixed rod 67. An abrasive 69 is installed at one end of the abrasive seat 66 and the outer end of the movable rod 68.
[0019] In use, the inner ring is placed outside the extension block 43, above the abrasive 69 on one side of the abrasive seat 66. The telescopic rod 45 extends and pushes the conical seat 46 upward. The conical seat 46 then pushes its moving rod 44 to move outward. The moving rod 44 drives the extension rod 42 and the extension block 43 to move away from the conical seat 46, thus tightening the inner ring. The inner ring rotates at high speed and passes between the abrasive 69 for grinding.
[0020] When the abrasive 69 needs to be replaced, the abrasive 69 is rotated to the upper or lower side of the inner ring by rotating the rotating disk 61. The used abrasive 69 is rotated to the other side so that it is no longer used, or it can be replaced with a finer abrasive for subsequent processing.
[0021] In this embodiment, specifically, a motor 2 is fixedly installed below the workbench 1, and the motor 2 is fixedly connected to the rotating seat 3. The motor 2 drives the rotating seat 3 to rotate, and the rotation of the rotating seat 3 drives the inner ring to rotate for grinding through the clamping mechanism 4.
[0022] In this embodiment, a handle is fixedly connected to the outside of the rotating disk 61. The handle facilitates the rotation of the rotating disk 61.
[0023] In this embodiment, specifically, a limiting rod 612 is elastically slidably connected below the rotating disk 61, and a limiting disk 51 is fixedly connected to the outer side of the upper end of the fixed base 5. The outer side of the limiting disk 51 has multiple notches, and the limiting rod 612 can be located inside the notches. By locking the limiting rod 612 through the notches, the rotating disk 61 is less likely to rotate and less likely to deviate during operation. Forcefully rotating the rotating disk 61 can disengage the limiting rod 612 from the notches, allowing it to be positioned and limited through another notch, facilitating rapid rotation of the rotating disk 61 at a certain angle.
[0024] In this embodiment, specifically, a second motor 63 is fixedly mounted above the mounting base 62, and a lead screw 64 is fixedly connected above the second motor 63. An internal threaded block 610 is threadedly connected to the outer side of the lead screw 64, and the internal threaded block 610 is movably connected to the movable rod 68. The up-and-down movement of the internal threaded block 610 drives the movable rod 68 to move up and down, which in turn drives the abrasive 69 to move up and down, enabling the grinding of the upper surface of inner rings of different thicknesses. Furthermore, the movable rod 68 causes multiple abrasive pieces 69 to descend, eliminating the need for readjustment of the thickness after replacing the abrasive 69.
[0025] In this embodiment, specifically, the lower end of the internal threaded block 610 passes through the movable rod 68, and both ends of the internal threaded block 610 are slidably connected to the movable rod 68. A spring 611 is provided between the internal threaded block 610 and the movable rod 68. The internal threaded block 610 descends and compresses the spring 611, which in turn compresses the movable rod 68 to descend. The movable rod 68 then causes the abrasive 69 on one side to flexibly contact the upper and lower end faces of the inner ring, avoiding direct contact and preventing excessive wear that could damage the inner ring.
[0026] In this embodiment, specifically, the sides of the multiple extension rods 42 that are close to each other can be in close contact. There is no gap between the extension rods 42, thereby reducing the outer dimensions of the extension rods 42 and the extension block 43, and enabling more inner rings with smaller inner diameters to be fixed.
[0027] In this embodiment, specifically, one end of the abrasive holder 66 and the outer end of the movable rod 68 are provided with a slot, and the abrasive 69 is inserted into the slot without any gap between the abrasive 69 and the slot. The abrasive 69 can be directly pulled out of the slot for replacement.
[0028] Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art and related fields based on the embodiments of this utility model without creative effort should fall within the protection scope of this utility model. Structures, devices, and operating methods not specifically described and explained in this utility model, unless otherwise specified or limited, shall be implemented according to conventional means in the art.
