Description

Technical Field

[0001] This utility model relates to the field of roller bearing technology, and in particular to a grinding device for processing roller bearings. Background Technology

[0002] Roller bearings are mechanical components that achieve low-friction rotational motion through rolling elements. They are widely used in mechanical equipment that needs to withstand heavy loads, high speeds, or complex motion trajectories. Their core design concept is to replace sliding friction with rolling friction, which significantly reduces energy loss and extends service life.

[0003] Grinding is an important step in the processing of roller bearings. The purpose of grinding is to remove the oxide layer, burrs and machining allowance after heat treatment. However, most traditional grinding equipment adopts a fixed structure and can only grind roller bearings of fixed size, which makes the grinding process less flexible. Utility Model Content

The support circular plate is located in the circular groove, and a bearing is embedded in the bottom of the support circular plate. A motor is fixedly installed at the top of the first groove, and the motor drives a rotating shaft. A rotating plate is fixedly installed at the top of the rotating shaft and rotates within the circular groove. A connecting shaft is fixedly installed at the top of one end of the rotating plate and is connected to the bearing. A second groove is provided at the other end of the rotating plate, and a second motor is installed in the second groove. The second motor drives a second rotating shaft, and a grinding roller is fixedly installed at the top of the second rotating shaft.

[0008] In addition, a preferred structure is that the inner wall of the groove is provided with a sliding groove on both sides, and four threaded holes and four through holes are provided at equal intervals at the bottom and top of the sliding groove.

[0009] In addition, in a preferred structure, sliders are fixedly installed on both sides of the motor, and the sliders slide within the grooves, with through holes provided in the sliders.

[0010] Furthermore, in a preferred configuration, the bolt passes through through hole one and through hole two and is then threaded into threaded hole three.

[0011] Furthermore, a preferred structure is that the inner wall of the circular groove is provided with an annular sliding groove.

[0012] In addition, a preferred structure is that a slider is fixedly provided on one side of the outer wall of the rotating plate, and the slider slides within the annular groove.

[0013] In addition, a preferred structure is that the top of the supporting circular plate and the bottom of the mounting plate are respectively provided with threaded hole two and threaded hole one.

Detailed Implementation

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0027] Reference Figure 1-8 A grinding device for processing roller bearings includes a worktable 1, a support circular plate 4, and bolts 10. The worktable 1 has a groove 11 on its side and a circular groove 12 on its top surface. The support circular plate 4 is located in the circular groove 12, and a bearing 9 is embedded in the bottom of the support circular plate 4. A motor 6 is fixedly installed on the top of the groove 11. The motor 6 drives a rotating shaft 61. A rotating plate 7 is fixedly installed on the top of the rotating shaft 61. The rotating plate 7 rotates within the circular groove 12. A connecting shaft 71 is fixedly installed on the top of one end of the rotating plate 7 and is connected to the bearing 9. A groove 72 is opened on the other end of the rotating plate 7. A motor 8 is installed in the groove 72 and drives a rotating shaft 81. A grinding roller 5 is fixedly installed on the top of the rotating shaft 81.

[0028] Among them, a cylinder 2 is fixedly installed on the top of the workbench 1, the cylinder 2 drives the mounting plate 21, the bottom of the mounting plate 21 is threaded with a pressure plate assembly 3, and the top of the support round plate 4 is threaded with a pressure plate assembly 3.

[0029] Meanwhile, grooves 73 are provided on both sides of the inner wall of groove 2 72, and four threaded holes 731 and four through holes 732 are provided at equal intervals at the bottom and top of groove 73.

[0030] Furthermore, sliders 82 are fixedly installed on both sides of motor 8. Slider 82 slides within slide groove 73. Slider 82 has through holes 821, which makes the movement of motor 8 more stable and facilitates limiting the movement of motor 8.

[0031] Meanwhile, bolt 10 passes through through hole 1 732 and through hole 2 821 and is then threaded into threaded hole 3 731 to limit the movement of motor 2 8, which facilitates the grinding of the roller bearing.

[0032] Meanwhile, an annular groove 121 is provided on the inner wall of the circular groove 12.

[0033] Furthermore, a slider 74 is fixedly installed on one side of the outer wall of the rotating plate 7. The slider 74 slides within the annular groove 121, making the rotating plate 7 rotate more stably within the circular groove 12.

[0034] Meanwhile, threaded holes 41 and 211 are respectively provided on the top of the supporting circular plate 4 and the bottom of the mounting plate 21.

[0035] Furthermore, both pressure plate assemblies 3 include a pressure plate 31, with threaded posts 32 and insert posts 33 respectively provided on both sides of the pressure plate 31. The threaded posts 32 of the two pressure plate assemblies 3 are threaded into threaded holes 211 and 41 respectively. The threaded connection facilitates quick replacement of the new pressure plate assembly 3 onto the support circular plate 4 and the mounting plate 21.

[0036] In this embodiment, the roller bearing to be polished is sleeved on the insert 33 of the bottom pressure plate assembly 3. Then, the cylinder 2 is started to drive the mounting plate 21 to descend. The insert 33 of the pressure plate assembly 3 installed at the bottom of the mounting plate 21 is inserted into the roller bearing. At this time, the roller bearing is clamped by the pressure plates 31 of the two pressure plate assemblies 3. Then, the motor 6 is started, and the motor 6 drives the rotating shaft 61 to rotate at a constant speed, thereby driving the rotating plate 7 to rotate synchronously in the circular groove 12. Since the connecting shaft 71 is connected to the supporting circular plate 4 through the bearing 9, and the downward pressure generated by the cylinder 2, the supporting circular plate 4 will not rotate. At the same time, the motor 8 is started to drive the rotating shaft 81 to rotate, thereby driving the polishing roller 5 to rotate synchronously. The polishing roller 5 then polishes the roller bearing.

[0037] When grinding roller bearings of other sizes is required, rotate the pressure plate 31 of the two pressure plate assemblies 3 to remove the two threaded pins 32 from the threaded holes 1 211 and 2 41. Then, remove the two pressure plate assemblies 3 from the mounting plate 21 and the support round plate 4. Replace with new pressure plate assemblies 3 and install them on the mounting plate 21 and the support round plate 4. Then, tighten the bolt 10 to remove it from the threaded hole 3 731, through hole 2 821, and through hole 1 732. Then, move the motor 2 8 to the new position. Then, after passing the bolt 10 through through hole 1 732 and through hole 2 821, thread it into the threaded hole 3 731 to limit the movement of the motor 2 8. At this point, roller bearings of other sizes can be placed into the two pressure plate assemblies 3 and then ground.

[0038] In this invention, by quickly replacing the two pressure plate assemblies 3 and simultaneously adjusting the position of the grinding roller 5, four different sizes of roller bearings can be ground, thus improving the flexibility of the grinding device.

[0039] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
