Description

Technical Field

[0001] This utility model relates to the field of clutch processing, and in particular to a clutch housing grinding mechanism. Background Technology

[0002] Currently, clutch housings in the automotive, construction machinery and other fields are generally made of materials such as aluminum alloy and cast iron, and are usually formed by casting. Due to the casting process (such as sand casting, pressure casting), their inner walls are prone to defects such as burrs, oxide scale, and sand holes.

[0003] The reference patent title is: A combined clutch housing inner wall grinding device (patent publication number: CN219853602U). It uses a support frame and a fixed seat fixed to the upper surface of the worktable. A sliding grinding motor is set on the surface of the support frame. The grinding motor is fixedly connected to the grinding roller. A clamping motor and a clamping assembly are set inside the fixed seat. The clutch housing is clamped on the surface of the fixed seat, and the grinding roller contacts the inner wall of the clutch housing. The relative rotation of the clamping assembly and the grinding roller realizes the grinding.

[0004] However, the following problems exist when implementing the above technical solutions: In the above devices, both the grinding motor and the clamping motor are fixed at a certain height, which limits the size of the clutch housing that the device can operate on; the grinding roller needs to contact the inner wall of the clutch housing, and the height of the grinding motor is fixed, which means that the height of a certain position of the clutch housing is determined. The clamping component can achieve bidirectional clamping, which determines the center position of the clutch housing. At this time, the center position of the clutch housing is fixed, and the height is also limited. Therefore, the diameter of the clutch housing that the device can clamp and grind is limited, and the scope of use is limited.

[0005] In summary, this utility model provides a clutch housing grinding mechanism. Utility Model Content

[0028] The specific embodiments of this utility model are described in detail below, but it should be understood that the protection scope of this utility model is not limited to the specific embodiments.

[0029] like Figures 1 to 5 As shown in the figure, an embodiment of the present invention provides a clutch housing grinding mechanism, comprising:

[0030] A clamping block 1 is fixedly mounted on the surface of the worktable, and a clamping assembly is provided on the surface of the clamping block 1; a receiving groove 2 is provided on the surface of the worktable.

[0031] A push block 3 is slidably disposed on the surface of the worktable. An adjustment mechanism is provided on the surface of the push block 3. The adjustment mechanism includes a processing block 4 slidably disposed on the side of the push block 3 near the clamping block 1. A sliding component is provided between the push block 3 and the processing block 4. The sliding component is slidably disposed inside the push block 3. A device block 5 is slidably connected inside the processing block 4. A positioning component is provided between the device block 5 and the processing block 4. The positioning component is rotatably disposed inside the processing block 4.

[0032] A sanding motor 6 is fixedly connected to the equipment block 5. A drive roller 7 is fixedly connected to the end of the output shaft of the sanding motor 6. A sanding disc 8 is detachably connected to the surface of the drive roller 7. The sanding motor 6 is electrically connected to an external power source.

[0033] In summary, the clutch housing grinding mechanism provided by this utility model includes a clamping block 1 and a pushing block 3 disposed on the surface of a processing table. The clutch housing is positioned by the clamping components on the surface of the clamping block 1, and a receiving groove 2 is opened on the surface of the processing table. Through the receiving groove 2, the clutch housing that the clamping block 1 can clamp is not limited by the surface of the processing table. The diameter of the clutch housing can be greater than the distance between the clamping block 1 and the surface of the processing table. A drive roller 7 that can move up, down, left, and right is provided on the surface of the pushing block 3. The drive roller 7 can contact the inner wall of clutch housings of more sizes. The height of the pushing block 3 and the clamping block 1 has less limitation on the size of the clutch housing that can be processed. At the same time, the drive roller 7 and the abrasive plate 8 are made detachable. After a period of use, the operator can replace them according to the wear condition, or replace different abrasive plates 8 according to different grinding requirements.

[0034] In some specific implementations, the sliding assembly includes a sliding shaft 9 fixedly disposed on the surface of the processing block 4, a sliding rod 10 threadedly connected inside the sliding shaft 9, the sliding rod 10 being rotatably connected to the push block 3, and a sliding groove 11 being formed on the surface of the push block 3, the sliding groove 11 being adapted to the sliding shaft 9; the sliding shaft 9 can be directly moved by the rotating sliding rod 10, thereby enabling the position of the sliding shaft 9 to be changed quickly;

[0035] In a further embodiment, a plurality of limiting rods 12 are fixedly connected inside the sliding groove 11, and a limiting groove 13 is formed on the surface of the sliding shaft 9. The limiting rods 12 are adapted to the limiting grooves 13. The presence of the limiting rods 12 and the limiting grooves 13 can restrict the sliding path of the sliding shaft 9 inside the pushing block 3, ensuring the horizontal sliding of the sliding shaft 9.

[0036] In some specific implementations, the positioning component includes a positioning gear 14 rotatably disposed inside the processing block 4, a positioning rack 15 fixedly connected to the surface of the equipment block 5, the positioning gear 14 meshing with the positioning rack 15, and a fixed rack 16 slidably connected inside the processing block 4, the fixed rack 16 meshing with the positioning gear 14; two positioning racks 15 and fixed racks 16 that slide in opposite directions but are both adapted to the positioning gear 14 are provided, so that when both racks are meshed with the positioning gear 14, the positioning gear 14 cannot continue to rotate, thereby restricting the position of the processing block 4;

[0037] In a further embodiment, the processing block 4 is internally threaded with a pressing rod 17, and a cone is fixedly connected to the end of the pressing rod 17. The fixed rack 16 is chamfered on the side near the pressing rod 17, and the cone fits against the fixed rack 16. A pressing spring 18 is fixedly connected between the fixed rack 16 and the processing block 4. The sliding of the pressing rod 17 can cause the fixed rack 16 to slide, thereby engaging the fixed rack 16 with the positioning gear 14 and restricting the rotation of the positioning gear 14.

[0038] In a further embodiment, a central rod is fixedly connected to the surface of the positioning gear 14, and a driving column 19 is slidably connected inside the processing block 4. The central rod and the driving column 19 are rotatably connected. A moving groove is opened inside the processing block 4, and the driving column 19 is adapted to the moving groove. Two support springs 20 are fixedly connected between the driving column 19 and the moving groove. Through the support springs 20, the positioning gear 14 can reciprocate within a certain range. When there is a difference in meshing between the fixed gear and the positioning gear 14, the fixed gear can cause the positioning gear 14 to move slightly to ensure meshing between the two.

[0039] In some specific implementations, the drive roller 7 has an insertion groove 21 on its surface, which is adapted to the end of the abrasive sheet 8. The insertion groove 21 includes a rectangular groove and an arc-shaped groove, which are connected. The rectangular groove is adapted to the end of the abrasive sheet 8. An extrusion column 22 is rotatably connected inside the drive roller 7, and the extrusion column 22 is slidably disposed inside the arc-shaped groove. The insertion groove 21 can accommodate both ends of the abrasive sheet 8, and the extrusion column 22 can extrude the abrasive sheet 8, thus preventing the abrasive sheet 8 from sliding out of the insertion groove 21.

[0040] In a further embodiment, the surface of the drive roller 7 is provided with an operating groove, and an operating ring 23 is threadedly connected inside the operating groove. The operating ring 23 is fixedly connected to the extrusion column 22. The position of the extrusion column 22 can be quickly adjusted through the operating ring 23. At the same time, since the operating ring 23 is threadedly connected to the drive roller 7, the operating ring 23 is difficult to change its angle independently, which makes it easy to maintain the position of the abrasive sheet 8.

[0041] In some specific implementations, a cylinder is fixedly connected to the surface of the worktable, and the piston rod inside the cylinder is fixedly connected to the push block 3; a limit block 24 is fixedly connected to the surface of the worktable, the cross-section of the limit block 24 is U-shaped, and the limit block 24 fits against the push block 3;

[0042] In some specific implementations, the clamping assembly includes a clamping motor, a rotating block, a bidirectional cylinder, and two clamping blocks 1. The clamping blocks 1 are fixedly connected to the piston rod inside the bidirectional cylinder, the bidirectional cylinder is fixedly connected to the rotating block, and the end of the output shaft of the clamping motor is fixedly connected to the rotating block.

[0043] The working principle of this utility model:

[0044] In use, first place the clutch housing between the two clamping blocks 1 to restrict the position of the clutch housing. Then, adjust the positions of the drive roller 7 and the abrasive disc 8 according to the position of the inner wall of the clutch housing. First, rotate the sliding rod 10. The rotation of the sliding rod 10 causes the sliding shaft 9 to slide. The sliding shaft 9 drives the processing block 4 to move. Then, rotate the pressing rod 17 to cause the fixed rack 16 to disengage from the positioning gear 14. Then, slide the equipment block 5 to change the position of the equipment block 5 and the drive roller 7. After the position is determined, reset the pressing rod 17. Then, start the cylinder to cause the drive roller 7 to slide into the clutch housing. The abrasive disc 8 is in contact with the inner wall of the clutch housing. Then, start the grinding motor 6 and the clamping motor to start grinding.

[0045] The above-disclosed embodiments are only a few specific examples of the present utility model. However, the embodiments of the present utility model are not limited thereto. Any changes that can be conceived by those skilled in the art should fall within the protection scope of the present utility model.
