Description

Technical Field

[0001] This utility model relates to the field of grinding device technology, specifically to a grinding device for the end face of a harvester drive shaft. Background Technology

[0002] During use, the drive shaft of a harvester may experience wear and corrosion, leading to increased surface roughness. Grinding can remove these irregular protrusions, making the surface smoother and thus improving the shaft's precision and performance.

[0003] In the existing technology, when the surface roughness of the harvester drive shaft increases, the usual practice is to replace it or send it back to the factory for reprocessing. However, due to the special use scenario of agricultural harvesters, sending the drive shaft back to the factory for reprocessing or calling in technical experts to handle the problem would delay the busy farming operations and is not practical. Therefore, we provide a grinding device for the end face of the harvester drive shaft to solve the above problems. Utility Model Content

[0004] To address the problems existing in the prior art, this utility model provides a grinding device for the end face of a harvester drive shaft. When grinding and repairing the end face of the drive shaft, it is not necessary to remove the harvester drive shaft; the operation can be performed on the harvester itself. It is simple to use, and the overall device is small in size. It can be operated by hand to grind and repair the end face of the harvester drive shaft without removing the harvester drive shaft and returning it to the factory for processing. This does not delay the busy farming season and is highly practical.

A second electric cylinder is fixedly installed on the upper surface of the sliding block. The second electric cylinder is distributed vertically, and its upper end is connected to the grinding mechanism. The limiting mechanism includes limiting holes and limiting pins. Multiple limiting holes are provided, and the multiple limiting holes are distributed at equal intervals along the bottom surface of the feed groove. The bottom surface of the feed groove is correspondingly distributed with scale lines located on one side of the limiting holes. The limiting pin is engaged and fixed in the corresponding limiting hole, and the limiting pin restricts the sliding block to the side away from the first electric cylinder to prevent the sliding block from continuing to move.

[0009] As a further optimization of the above solution, the grinding mechanism includes a fixed cylinder, which is a cylindrical structure with one end open. A motor is fixedly installed at one end of the fixed cylinder, and a connecting shaft is fixedly installed on the rotating shaft of the motor. A grinding wheel is detachably connected to the end of the connecting shaft, and the grinding wheel extends out of the open end of the fixed cylinder.

[0017] This utility model discloses a grinding device for the end face of a harvester drive shaft. When the grinding mechanism in this utility model grinds and repairs the end face of the drive shaft, it can be operated on the harvester without removing the harvester drive shaft. It is simple to use, and the overall device is small in size. It can be operated by hand to grind and repair the end face of the harvester drive shaft without removing the harvester drive shaft and returning it to the factory for processing. It does not delay the busy farming season and is highly practical.

[0018] This utility model provides a grinding device for the end face of a harvester drive shaft. When grinding drive shafts of different diameters, the model of the outer cylinder and the grinding wheel can be changed, making it convenient to grind drive shafts of various diameters.

[0019] This utility model provides a grinding device for the end face of a harvester drive shaft. Because the outer cylinder is sleeved outside the drive shaft, dust particles during the grinding process are not easily diffused outward, and it also has a dust suppression function.

[0020] This utility model provides a grinding device for the end face of a harvester drive shaft. Due to the attraction of the magnetic ring, the end face of the drive shaft is always in close contact with the grinding wheel, which solves the problem that non-professionals cannot stably perform grinding operations.

[0021] This utility model provides a grinding device for the end face of a harvester drive shaft. A limiting pin restricts the sliding block to the side away from the first electric cylinder to prevent the sliding block from moving further.

It can be operated by non-professionals.

[0022] This utility model discloses a grinding device for the end face of a harvester drive shaft.

[0029] Please refer to the instruction manual appendix. Figure 1-4 This utility model provides a technical solution: a grinding device for the end face of a harvester drive shaft, comprising: a grinding mechanism 6 and an adjusting base 1. The grinding mechanism 6 is used to grind the end face of the harvester drive shaft; the adjusting base 1 is used to support the grinding mechanism 6. A handle 4 is fixedly provided on one side of the adjusting base 1. By holding the handle 4, the grinding mechanism 6 is operated to grind the end face of the harvester drive shaft. The overall device is small in size and can be operated by hand to grind and repair the end face of the harvester drive shaft without disassembling and returning the harvester drive shaft to the factory for processing, thus not delaying the busy farming season and having strong practicality.

[0030] Furthermore, when the grinding mechanism 6 provided in this utility model grinds and repairs the end of the transmission shaft, it can be operated on the harvester without removing the harvester transmission shaft, which is simple to use; however, it should be noted that for some transmission shafts whose ends are not exposed, such as universal drive shafts, cross universal couplings and telescopic drive shafts, the side baffles need to be removed, but this is relatively simple and does not require professional personnel to operate.

[0031] In this utility model, the grinding mechanism 6 includes a fixed cylinder 7, which is a cylindrical structure with one end open. A motor 8 is fixedly installed at one end of the fixed cylinder 7, and a connecting shaft 9 is fixedly installed on the rotating shaft of the motor 8. A grinding wheel 10 is detachably connected to the end of the connecting shaft 9. The grinding wheel 10 extends out of the open end of the fixed cylinder 7. When the fixed cylinder 7 is sleeved on the end of the transmission shaft, the grinding wheel 10 is in contact with the end face of the transmission shaft. When the motor 8 is started, the motor 8 drives the grinding wheel 10 to rotate through the connecting shaft 9. The roughness of the surface of the grinding wheel 10 is used to grind and repair the end face of the transmission shaft.

[0032] The outer ring of the fixed cylinder 7 has an external thread structure, and the open end of the fixed cylinder 7 is provided with an outer cylinder 12. The inner ring of the outer cylinder 12 has an internal thread structure. The outer cylinder 12 and the fixed cylinder 7 are connected by the internal and external thread structure. When grinding drive shafts of different diameters, the models of the outer cylinder 12 and the grinding wheel 10 can be changed, which is convenient for grinding drive shafts of various diameters.

[0033] Since the outer cylinder 12 is fitted outside the drive shaft, dust particles during the grinding process are not easily diffused outwards, and it also has the function of dust suppression.

[0034] A magnetic ring 11 is fixedly installed at the open end of the fixed cylinder 7. The magnetic ring 11 is used to attract the end of the harvester's transmission end to fit against the grinding wheel 10. Due to the attraction of the magnetic ring 11, the end face of the transmission shaft and the grinding wheel 10 are always in close contact, which solves the problem that non-professionals cannot stably achieve grinding operation.

[0035] Considering that non-professionals cannot effectively control grinding precision, a limiting mechanism for controlling grinding feed precision is provided on the adjusting base 1. A feed groove 2 is provided on the upper surface of the adjusting base 1. A first electric cylinder 3 is fixedly installed on the inner wall of one side of the feed groove 2. The first electric cylinder 3 is horizontally arranged, and a sliding block 18 is fixedly connected to its end. A second electric cylinder 5 is fixedly installed on the upper surface of the sliding block 18. The second electric cylinder 5 is vertically distributed, and its upper end is connected to the grinding mechanism 6. The limiting mechanism includes a limiting... The device includes holes 20 and limit pins 19. Multiple limit holes 20 are provided, which are evenly distributed along the bottom surface of the feed groove 2. The bottom surface of the feed groove 2 is correspondingly distributed with scale lines, which are located on one side of the limit holes 20. The limit pins 19 are engaged and fixed in the corresponding limit holes 20, and the limit pins 19 restrict the sliding block 18 to the side away from the first electric cylinder 3 to prevent the sliding block 18 from continuing to move. Combined with the scale lines on one side of the limit holes 20, the feed distance of the grinding wheel 10 can be limited, thereby controlling the grinding accuracy. This device can be operated even by non-professionals.

[0036] In practical use, when the end face of the drive shaft has scratches or rough surfaces with a maximum depth of about 0.1 mm, the baffle at the end of the drive shaft needs to be removed first. Then, holding the handle 4, the outer cylinder 12 is fitted onto the end of the drive shaft so that the grinding wheel 10 is in contact with the end face of the drive shaft. Then, the limiting pin 19 is engaged in the limiting hole 20 corresponding to the side of the sliding block 18 away from the first electric cylinder 3. Here, the distance between the side of the limiting hole 20 close to the sliding block 18 and the sliding block 18 is greater than or equal to 0.1 mm. Then, the grinding mechanism 6 is started to grind the end face of the drive shaft. During the grinding process, the first electric cylinder 3 is used to push the sliding block 18 so that the grinding wheel 10 grinds and repairs the end face of the drive shaft. Due to the limitation of the limiting pin 19, the maximum feed value of the grinding wheel 10 is determined, which makes it easy to intuitively control the feed accuracy without the need for professional personnel to operate.

[0037] Furthermore, a suction pump 13 is installed on the upper end of the fixed cylinder 7, and a suction hole 14 is also provided on the fixed cylinder 7. One end of the suction hole 14 is connected to the air inlet of the suction pump 13, and the other end is connected to the inside of the fixed cylinder 7. When the suction pump 13 is started during the grinding of the end face of the drive shaft, the suction pump 13 generates suction force, which can suck the dust particles into the inside of the fixed cylinder 7, preventing the dust particles from spreading outward or affecting the grinding accuracy of the grinding wheel 10 on the end face of the drive shaft, and further suppressing dust.

[0038] In actual use, a filter pad 15 is provided at the end of the suction hole 14 away from the suction pump 13, so that dust particles can be filtered out inside the fixed cylinder 7.

[0039] A guide bucket 16 is fixedly installed at the open end of the fixed cylinder 7. The guide bucket 16 has a conical structure, and the end of the guide bucket 16 facing the inside of the fixed cylinder 7 has a small opening. The end of the guide bucket 16 facing the inside of the fixed cylinder 7 has a dust inlet 17 that communicates with the inside of the fixed cylinder 7. The guide bucket 16 is designed so that dust particles can enter the fixed cylinder 7 and are not easily discharged, thus achieving the purpose of dust collection.

[0040] The guide bucket 16 is elastic. When the grinding wheel 10 and the outer cylinder 12 are removed, the guide bucket 16 can be flipped to the outside of the fixed cylinder 7, so that the dust particles in the fixed cylinder 7 can be discharged smoothly and cleaning is convenient.
