Description

Technical Field

[0001] The utility model relates to the technical field of wheel barrow wheel processing, in particular to a grinding device for producing wheel barrow wheels. Background Art

[0002] The spoke is a device that protects the rim and spokes of a vehicle wheel. It is characterized by a pair of circular cover plates. The diameter of the cover plates is close to the diameter of the rim. There is a hole in the center of the cover plates that is larger than the wheel's rotating axis. There is an opening near the edge of the cover plates. There is an annular wheel plate on the edge of the cover plates. The curved surface of the wheel plate can fit tightly with the curved surface of the rim. The circular cover plates are welded to both sides of the rim to form spokes.

[0003] During the production process of wheels, it is necessary to grind the welding joints between the circular cover plate and the rim through a grinding device to remove the welding slag at the welding joints. However, the existing technology usually requires manual fixation of the wheel on a fixture and then grinding it through a grinding device. When the wheel is installed on the fixture, the grinding process will be terminated, resulting in low production efficiency.

The processing device automatically clamps the wheel through the automatic clamping component, and the driving component drives the mounting turntable to rotate. Under the joint action of the automatic clamping component and the grinding component, the burrs on the outer wall of the wheel can be continuously polished, and there is no idle period for grinding the wheel, thereby improving production efficiency.

[0005] However, the above processing device still requires manual placement of the wheel on the automatic clamping assembly, and manual unloading is required after grinding is completed. The labor intensity of the workers is relatively high, and the workers will become fatigued after long-term mechanized labor, resulting in reduced production efficiency. Utility Model Content

[0028] In the above specific embodiment, the welded wheel 27 is placed vertically on the material guide frame 2, and the wheel 27 is driven to move on the material guide frame 2 by the conveyor belt 3. The wheel 27 is positioned by the material blocking rod 28 so that the wheel 27 is in the grasping position. At this time, the wheel 27 is clamped by the clamping mechanism and moved to the support frame 23. The wheel 27 is lifted by the support wheel 5, and the first driving mechanism drives the support wheel 5 to rotate. Under the action of the support wheel 5, the wheel 27 rotates on the support frame 23. At this time, the welding part of the wheel is polished by the grinding mechanism. After the grinding is completed, the first hydraulic rod 6 drives the support seat 4 to flip downward, and the wheel 27 is detached from the support seat 4 under the action of gravity, thereby realizing automatic loading and unloading of the wheel 27, effectively reducing the labor intensity of the staff, and thus improving the production efficiency of the product.

[0029] In this embodiment, the clamping mechanism includes a bearing frame 7, which is fixedly mounted on the right end of the guide frame 2. A rotating shaft 8 is rotatably mounted on the top of the bearing frame 7. A second driving mechanism for driving the rotating shaft 8 to rotate is provided on the bearing frame 7. Connecting rods 9 are slidably mounted on both ends of the rotating shaft 8. A clamping rod 10 is fixedly mounted on the end of the connecting rod 9. A connecting seat 11 is fixedly mounted on the end of the clamping rod 10 away from the connecting rod 9. The connecting seat 11 is rotatably connected to the push rod of the cylinder 26. The cylinder 26 is fixedly mounted on the fixing frame 12. The fixing frame 12 is fixedly mounted on the base 1. The clamping rods 10 are driven by the cylinder 26 to approach each other to clamp the wheel 27.

[0030] In this embodiment, the second driving mechanism includes a first motor 13, which is fixedly mounted on the side wall of the bearing frame 7. A first gear 14 is fixedly mounted on the power output shaft of the first motor 13, and a second gear 15 is fixedly mounted on the rotating shaft 8. The first gear 14 is meshed with the second gear 15. The first motor 13 drives the rotating shaft 8 to rotate on the bearing frame 7 through a gear set.

[0031] In this embodiment, a through hole 16 is opened at the axis of the rotating shaft 8, and the cross section of the through hole 16 is hexagonal. The shape of the connecting rod 9 matches the through hole 16, and can drive the clamping rod 10 to rotate synchronously when the rotating shaft 8 rotates.

[0032] In this embodiment, clamping blocks 17 are rotatably installed at both ends of the clamping rod 10. The clamping blocks 17 are cylindrical structures. The clamping blocks 17 are concentric with the wheel 27. When the clamping rod 10 clamps the wheel 27, the clamping blocks 17 abut against the side walls of the wheel 27. The clamping blocks 17 clamp the wheel 27 and move the wheel 27 from the guide frame 2 to the support seat 4.

[0033] In this embodiment, the first driving mechanism includes a second motor 18, which is fixedly mounted on the bottom of the support seat 4. A driving wheel 19 is fixedly mounted on the power output shaft of the second motor 18, and driven wheels 20 are respectively fixedly mounted on the rotating shafts of the two groups of support wheels 5. Preferably, the driving wheel 19 and the driven wheel 20 are both sprocket wheels, and the driving wheel 19 and the driven wheel 20 are connected in series through a chain 21. The second motor 18 drives the support wheel 5 to rotate, and the wheel 27 is placed between the two groups of support wheels 5. When the support wheel 5 rotates, the wheel 27 will be driven to rotate synchronously.

[0034] In this embodiment, a layer of rubber material is attached to the surface of the support wheel 5, so as to increase the friction between the support wheel 5 and the wheel 27 and prevent the support wheel 5 from idling.

[0035] In this embodiment, the grinding mechanism includes a second hydraulic rod 22, which is fixedly mounted on the base 1. The second hydraulic rod 22 is fixedly mounted on one end of the base 1 close to the support seat 4. A support frame 23 is fixedly mounted on the push rod of the second hydraulic rod 22. A grinding block 24 is fixedly mounted on the top of the support frame 23.

[0036] In this embodiment, a collection box 25 is provided below the support frame 23 . The collection box 25 is fixedly mounted on the side wall of the base 1 . The polished wheels 27 fall into the collection box 25 for collection.

[0037] The specific working process of the utility model is as follows: the welded wheel 27 is placed vertically on the guide frame 2, and the wheel 27 is driven to move on the guide frame 2 by the conveyor belt 3. When the front wheel 27 moves to the grabbing position, it will be blocked by the blocking rod 28. At this time, the cylinder 26 drives the clamping rod 10 to approach each other, and the wheel 27 is clamped by the clamping block 17. After the wheel 27 is clamped, the first motor 13 drives the rotating shaft 8 to rotate, and the clamping rod 10 rotates on the bearing frame 7 under the action of the rotating shaft 8, and the wheel 27 is moved from the guide frame 2 to the support seat 4. The wheel 27 is placed between the two groups of support wheels 5. At this time, the second motor 18 drives the support wheel 5 to rotate, and the wheel 27 rotates synchronously under the drive of the support wheel 5. The second hydraulic rod 22 drives the support frame 23 to move toward the support seat 4, and the welding part of the wheel 27 is polished by the polishing block 24. After the polishing is completed, the push rod of the first hydraulic rod 6 retracts, so that the support seat 4 flips downward. At the same time, the cylinder 26 drives the clamping rods 10 to move away from each other. Under the action of gravity, the wheel 27 detaches from the support seat 4 and falls into the collection box 25. The above steps are repeated to realize automatic loading and unloading of the wheel 27, which effectively reduces the labor intensity of the staff and improves the production efficiency of the product.
