DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figures 1 to 4 , the utility model provides embodiments:

[0024] An inner ring grinding device for bearing processing comprises a base 1;

[0025] A processing table 2 is rotatably arranged on the base 1, a lifting cylinder 3 is arranged inside the base 1, the processing table 2 rotates on the surface of the lifting cylinder 3, a clamping mechanism 4 for positioning the bearing is arranged on the surface of the processing table 2, a bracket 5 is installed at the output end of the lifting cylinder 3, an inner ring grinding mechanism 6 for grinding the bearing is arranged at the bottom of the bracket 5, and an adjusting mechanism 7 for adjusting the horizontal position of the inner ring grinding mechanism 6 is arranged inside the bracket 5.

[0026] The adjusting mechanism 7 includes a main shaft 71, a first motor 72, a threaded rod 73, a receiving groove 74 and a traction block 75. The four receiving grooves 74 are in a cross structure and pass through the surface of the bracket 5. The threaded rod 73 rotates on the inner wall of the receiving groove 74, and the main shaft 71 rotates inside the bracket 5. The main shaft 71 and the threaded rod 73 are transmitted through a bevel gear set. The traction block 75 slides on the inner wall of the receiving groove 74 and is connected with the threaded rod 73. The traction block 75 is connected with the inner ring grinding mechanism 6.

[0027] See also Figure 2 The first motor 72 drives the threaded rod 73 to rotate through the bevel gear set. When the threaded rod 73 rotates, the traction block 75 is driven to move linearly inside the accommodating groove 74. At this time, the vertical distance between the traction block 75 and the main shaft 71 can be adjusted, which means that the traction block 75 can adapt to bearings of different radii.

[0028] The inner ring grinding mechanism 6 includes a connecting seat 61, a rotating shaft 62, a grinding wheel 63 and a second motor 64. The connecting seat 61 is fixed to the bottom of the traction block 75 and is attached to the bottom of the frame. The rotating shaft 62 rotates at the bottom of the connecting seat 61. The grinding wheel 63 is fixed to the bottom end of the rotating shaft 62. The second motor 64 is fixed to the bottom of the connecting seat 61 and is connected to the rotating shaft 62 by belt drive.

[0029] See also Figure 1 and 2 The second motor 64 can drive the rotating shaft 62 to rotate by belt transmission, and the rotating shaft 62 can drive the grinding wheel 63 to rotate synchronously, thereby realizing the grinding of the inner ring of the bearing. When placing the bearing, the four scrapers 82 must first be moved to the central area of ​​the bracket 5 so that the scrapers 82 can pass through the bearing and contact the processing table 2.

[0030] A debris cleaning mechanism 8 is provided at the bottom of the grinding wheel 63, and the debris cleaning mechanism 8 includes a connecting rod 81 movably arranged at the bottom of the grinding wheel 63, and a scraper 82 fixed under the connecting rod 81, and both ends of the scraper 82 are inclined. The connecting rod 81 and the grinding wheel 63 are movably connected through an elastic structure 9.

[0031] See also Figure 1 and 2Since the processing table 2 is constantly rotating and the scraper 82 is fixed, the processing table 2 can drive the debris on its surface to move synchronously. The moving debris is blocked by the scraper 82 and stays under the scraper 82, thereby achieving the purpose of collecting the debris.

[0032] The elastic structure 9 includes a spring 91, a cavity 92 and a limit plate 93. The cavity 92 is opened inside the grinding wheel 63. One end of the connecting rod 81 extends into the cavity 92. The limit plate 93 is fixed to the top of the connecting plate and slidably set in the cavity 92. The spring 91 is fixed between the cavity 92 and the limit plate 93.

[0033] See also Figure 3 When the bracket 5 moves downward, it can drive the connecting rod 81 to move synchronously through the grinding wheel 63. At this time, the scraper 82 will contact the processing table 2, but the grinding wheel 63 may not have dropped into place. Therefore, as the grinding wheel 63 continues to move downward, the grinding wheel 63 moves on the upper end surface of the connecting rod 81. At this time, the upper end of the connecting rod 81 will compress the spring 91 through the limit plate 93 inside the cavity 92, thereby making room for the grinding wheel 63 to move downward.

[0034] The clamping mechanism 4 includes a vertical plate 41, a clamping cylinder 42 and a clamping plate 43. The vertical plate 41 is fixed to the edge of the surface of the processing table 2, the clamping cylinder 42 is fixed to the surface of the vertical plate 41, and the clamping plate 43 is installed at the output end of the clamping cylinder 42. A support portion 44 is provided at the bottom of the clamping plate 43. Both the clamping plate 43 and the support portion 44 are provided in an arc-shaped structure. Please refer to Figure 1 and 4 The clamping cylinder 42 is actuated to drive the clamping plate 43 to move, and the bearing is clamped and fixed by the two clamping plates 43 .

[0035] A third motor 10 is arranged inside the base 1, a sleeve 11 is fixed to the bottom of the processing table 2, the sleeve 11 is sleeved on the surface of the lifting cylinder 3, and the output end of the third motor 10 is connected to the sleeve 11 through gear transmission.

[0036] See also Figure 1 and 4 The third motor 10 drives the sleeve 11 to rotate through gear transmission inside the body, and then drives the processing table 2 to rotate as a whole through the sleeve 11. The processing table 2 can drive the bearing to rotate as a whole through the clamping mechanism 4. Since the grinding wheel 63 is fixed, the continuously rotating bearing can make the inner wall of its inner wall contact with the grinding wheel 63 at one place, thereby achieving the effect of grinding the inner wall of the bearing.

[0037] In the present utility model, unless otherwise clearly stipulated and limited, the terms such as "installation", "setting", "connection", "fixation" and "screw-on" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integrated connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. Unless otherwise clearly defined, ordinary technicians in this field can understand the specific meanings of the above terms in the utility model according to the specific circumstances.

[0038] In summary, the above are only preferred embodiments of the present invention and are not intended to limit the scope of implementation of the present invention. All equivalent changes and modifications to the shapes, structures, features and spirits described in the claims of the present invention should be included in the claims of the present invention.
