Description

Technical Field

[0001] The present invention relates to the technical field of grinding machines, and more specifically, to a grinding machine for the surface of a motor shaft. Background Art

[0002] During the processing of a motor shaft, in order to ensure the dimensional accuracy of the motor shaft, improve the surface quality, and thus ensure the overall performance and reliability of the motor, it is necessary to perform a grinding treatment on the surface of the motor shaft. A grinding machine is often borrowed to improve the surface finish and accuracy of the motor shaft and remove impurities such as burrs and oxide skins on the surface to meet the performance requirements and assembly needs of the motor.

[0003] Before the traditional grinding machine performs a grinding operation on the surface of the motor shaft, it is usually necessary for workers to accurately place the shafts on the fixture of the equipment one by one. Then, the outer surface of the shaft is ground by the grinding mechanism on the equipment. When replacing another shaft, the operator needs to repeatedly pick up the shaft and align it with the fixture on the equipment, and the operation process is cumbersome and the grinding efficiency is low.

[0004] When accurately placing the shaft to be processed on the fixture of the equipment, it is usually required that the operator first carry the turnover box containing the shaft from the ground to the operating table of the equipment. Since the height difference between the tabletop and the ground is large and the weight of the shaft is large, it is not convenient for the operator to carry and has poor flexibility.

[0005] Before grinding the outer surface of the shaft, it is necessary to adjust the position of the fixture according to the length of the shaft first. Therefore, during the adjustment process, it is necessary to repeatedly disassemble the bolts to achieve this. Due to the low disassembly efficiency, it is not convenient to flexibly adjust the position of the fixture. Summary of the Invention

[0034] In order to make the technical means, creative features, achieved purposes and functions of the present invention easy to understand, the present invention will be further described below in conjunction with specific implementation manners.

[0035] Such as Figure 1 , Figure 4 , Figure 5 , Figure 8 and Figure 9As shown, a motor shaft surface grinder described in the present invention includes an operating table 1, a lifting structure 5 installed on the operating table 1, a feeding structure 6 arranged on the operating table 1, and a supporting structure 7 connected to the operating table 1; a hydraulic rod 601 is fixedly connected to the edge of the operating table 1, a plurality of inclined plates 603 are fixedly connected to the bottom of the storage frame 503, a mounting strip 604 is fixedly connected to the inner wall of the storage frame 503, and two guide plates 605 are fixedly connected to the mounting strip 604. Since two guide plates 605 parallel to the inclined plates 603 are installed inside the storage frame 503 through the mounting strip 604, and the distance between the guide plates 605 and the inclined plates 603 can be adjusted by disassembling the mounting strip 604. , so as to facilitate adapting to motor shafts of different sizes. Two support sleeves 606 are fixedly connected to the operating table 1, and a blanking plate 607 is fixedly connected to the top of the support sleeve 606. A baffle 609 is slidably connected to the support sleeve 606. A guide rod 608 is fixedly connected inside the support sleeve 606. The baffle 609 and the guide rod 608 are slidably connected. The abutment bar 612 at the bottom of the connecting bar 611 will first abut the baffles 609 on both sides, driving the baffles 609 to slide upward along the guide rod 608 and pulling the tension spring 610. When the loading rack 602 rises to the top, the two baffles 609 also rise to the top. At this time, the motor shaft on the loading rack 602 rolls along the two blanking plates 607 to the support rack Between the four rotating wheels 703 on 701, a tension spring 610 is fixedly connected between the bottom surface of the baffle 609 and the support sleeve 606. Since the baffle 609 is in an "L"-shaped structure, it effectively ensures that the motor shaft rolls accurately between the four rotating wheels 703. The center position of the loading rack 602 is fixedly connected with a connecting strip 611, and the bottom of the connecting strip 611 is fixedly connected with a resistance strip 612. Since the end of the loading rack 602 is in an "L"-shaped structure, the end of the loading rack 602 always blocks the next motor shaft from rolling to the bottom of the loading rack 602 during the rising process, thereby avoiding the next motor shaft blocking the loading rack 602 from resetting. At this time, the motor shaft inside the storage frame 503 is moved along the inclined plate 603 and the guide plate 605. The spacing between them rolls to the bottom of the inclined plate 603 one by one, and while the storage frame 503 drives the motor shaft to lift, the inclined surface at the bottom of the loading rack 602 first contacts the outer wall of the motor shaft and squeezes the motor shaft, causing the motor shaft to move upward along the inclined plate 603 until it no longer blocks the loading rack 602. When the storage frame 503 rises to the maximum distance, the loading rack 602 and the inclined plate 603 are level with each other. At this time, the motor shaft on the inclined plate 603 rolls onto the loading rack 602 under the action of gravity, and then the hydraulic rod 601 drives the loading rack 602 to move upward, and the loading rack 602 drives the motor shaft to move upward until the end of the loading rack 602 is level with the top of the support sleeve 606, while the loading rack 602 is moving upward.

[0036] Specifically, as Figure 1 , Figure 5 and Figures 7 - 9 shown, two guiding columns 502 are fixedly connected to the outer wall of the operating table 1. A storage frame 503 is slidably connected between the two guiding columns 502. The motor shaft to be polished is transported to the vicinity of the equipment through a turnover box, and then the motor shaft is poured from the turnover box into the interior of the storage frame 503. Two mounting frames 501 are fixedly connected to the edge of the operating table 1. The tops of the two guiding columns 502 are respectively fixedly connected to the adjacent mounting frames 501. A driving plate 504 is slidably connected between the two guiding columns 502. The bottom of the storage frame 503 is fixedly connected to the driving plate 504. A third lead screw 505 is rotatably connected to the outer wall of the operating table 1. Then, a fourth motor 506 drives the third lead screw 505 to rotate. The driving plate 504 is threadedly connected to the third lead screw 505. The third lead screw 505 drives the driving plate 504 to move upward. A fourth motor 506 is fixedly connected to the outer wall of the operating table 1. The bottom of the third lead screw 505 is fixedly connected to the output shaft of the fourth motor 506. The driving plate 504 drives the storage frame 503 to slide upward along the two guiding columns 502. The storage frame 503 drives the motor shaft inside to move upward until the top surface of the storage frame 503 abuts against the two mounting frames 501. At this time, the motor shaft is quickly transported from the ground to the tabletop of the operating table 1, solving the problem of inconvenient handling due to the high tabletop of the operating table 1 and improving the handling efficiency.

[0037] Specifically, as Figure 1 , Figure 4 and Figures 7 - 9 shown, a support frame 701 is fixedly connected to the operating table 1. Two rotating wheels 703 are rotatably connected to each of the two mounting plates 702. The rotating wheels 703 rotate with the mounting plates 702, with strong stability and can reduce the friction with the motor shaft.

[0038] Specifically, as Figure 1 , Figure 3 , Figure 6 and Figure 7As shown, two third guide rails 401 are fixedly connected to the operation table 1. A second hydraulic cylinder 405 is fixedly connected to the top end of the carriage 402. The telescopic end of the second hydraulic cylinder 405 is fixedly connected to a center point 406. Then, the telescopic end of the second hydraulic cylinder 405 at the top end of the carriage 402 extends outwards, driving the center point 406 to abut against the end face of the rotating shaft of the motor. A connecting seat 407 is fixedly connected to the operation table 1. A tailstock 408 is rotatably connected to the connecting seat 407. At the same time, the tailstock 408 on the connecting seat 407 is used to clamp the rotating shaft of the motor, so that the rotating shaft of the motor can be effectively fixed. A third motor 409 is fixedly connected to the operation table 1. Second belt pulleys 410 are fixedly connected to the output shaft of the third motor 409 and the end of the tailstock 408 respectively. A second belt 411 is wound between the two second belt pulleys 410. The third motor 409 rotates through the second belt pulley 410 on the output shaft. The second belt pulley 410 on the output shaft of the third motor 409 drives the other second belt pulley 410 at the end of the tailstock 408 to rotate through the second belt 411. The second belt pulley 410 drives the tailstock 408 and the rotating shaft of the motor to rotate. A second lead screw 403 is rotatably connected to the operation table 1. The carriage 402 is threadedly connected to the second lead screw 403. A handle 404 is fixedly connected to the end of the second lead screw 403. At the same time, the center position of the rotating shaft of the motor is placed on four rotating wheels 703, with strong stability, thus ensuring uniform grinding of the outer wall of the subsequent rotating shaft of the motor and improving the grinding effect. By rotating the handle 404, the second lead screw 403 at the bottom of the carriage 402 can be driven to rotate. The second lead screw 403 can drive the carriage 402 to slide along the two third guide rails 401, thereby facilitating the rapid adjustment of the distance between the center point 406 and the tailstock 408 and adapting to rotating shafts of different lengths, with strong flexibility.

[0039] Specifically, as Figures 1 - 3As shown in the figure, a mounting base 201 is fixedly connected to the operation table 1. A sliding seat 203 is slidably connected between two first guide rails 202. Two second guide rails 206 are fixedly connected to the sliding seat 203. A support seat 207 is slidably connected between the two second guide rails 206. A first lead screw 204 is rotatably connected to the mounting base 201. The sliding seat 203 is threadedly connected to the first lead screw 204. An end of the mounting base 201 is fixedly connected to a first motor 205. An output shaft of the first motor 205 is fixedly connected to an end of the first lead screw 204. After the motor shaft is fixed, it needs to be polished. At this time, the first motor 205 located at the end of the mounting base 201 drives the first lead screw 204 to rotate. The first lead screw 204 drives the sliding seat 203 to move horizontally along the two first guide rails 202, thereby facilitating the horizontal movement of the grinding wheel 302. A first hydraulic cylinder 208 is fixedly connected to the sliding seat 203. An end of the telescopic rod of the first hydraulic cylinder 208 is fixedly connected to the bottom of the support seat 207. At the same time, the first hydraulic cylinder 208 is used to drive the support seat 207 to move horizontally along the second guide rail 206, so as to realize the all-round polishing of the motor shaft, and the operation efficiency is high.

[0040] Specifically, as Figures 1 - 3 shown in the figure, a drive shaft 301 is rotatably connected to the support seat 207. A second motor 303 is fixedly connected to the top of the support seat 207. The drive shaft 301 drives the grinding wheel 302 to rotate and polish the surface of the motor shaft. A first pulley 304 is fixedly connected to an output shaft of the second motor 303 and an end of the drive shaft 301. The second motor 303 drives the first pulley 304 on the output shaft to rotate. A first belt 305 is wound between the two first pulleys 304. The first pulley 304 drives another first pulley 304 and the drive shaft 301 to rotate through the first belt 305, and the grinding efficiency is high.

[0041] When the present invention is in use, the motor shaft to be polished is transported to the vicinity of the equipment by a turnover box, and then the motor shaft is poured from the turnover box into the interior of the storage frame 503. Then, a fourth motor 506 drives a third lead screw 505 to rotate. The third lead screw 505 drives a drive plate 504 to move upward. The drive plate 504 drives the storage frame 503 to slide upward along the two guide posts 502. The storage frame 503 drives the motor shaft inside to move upward until the top surface of the storage frame 503 abuts against the two mounting brackets 501. At this time, the motor shaft is quickly transported from the ground to the tabletop of the operation table 1, solving the problem of inconvenient handling due to the high tabletop of the operation table 1 and improving the handling efficiency;

[0042] Since two guide plates 605 parallel to the inclined plate 603 are installed inside the storage frame 503 through the mounting strip 604, and the distance between the guide plate 605 and the inclined plate 603 can be adjusted by disassembling the mounting strip 604, it is convenient to adapt to motor shafts of different sizes. At this time, the motor shafts inside the storage frame 503 roll one by one along the distance between the inclined plate 603 and the guide plate 605 to the bottom of the inclined plate 603. At the same time, during the process of the storage frame 503 driving the motor shafts to rise, the inclined surface at the bottom of the loading rack 602 first contacts the outer wall of the motor shaft and squeezes the motor shaft, causing the motor shaft to move upward along the inclined plate 603 until it no longer blocks the loading rack 602. When the storage frame 503 rises to the maximum distance, the loading rack 602 and the inclined plate 603 are horizontal to each other. At this time, the motor shafts on the inclined plate 603 roll onto the loading rack 602 under the action of gravity. Then, the hydraulic rod 601 drives the loading rack 602 to move upward, and the loading rack 602 drives the motor shafts to move upward until the end of the loading rack 602 is horizontal with the top of the support sleeve 606. Since the end of the loading rack 602 has an "L"-shaped structure, during the upward movement of the loading rack 602, its end always blocks the next motor shaft from rolling to the bottom of the loading rack 602, thus preventing the next motor shaft from blocking the reset of the loading rack 602. At the same time, during the upward movement of the loading rack 602, the contact strips 612 at the bottom of the connecting strip 611 will first contact the baffles 609 on both sides, driving the baffles 609 to slide upward along the guide rods 608 and stretching the tension springs 610. When the loading rack 602 rises to the top, the two baffles 609 also rise to the top. At this time, the motor shafts on the loading rack 602 roll along the two blanking plates 607 between the four runners 703 on the support frame 701. Since the baffles 609 have an "L"-shaped structure, it effectively ensures that the motor shafts accurately roll between the four runners 703, and the runners 703 rotate with the mounting plate 702, with strong stability and the ability to reduce the friction with the motor shafts;

[0043] Next, the telescopic end of the second hydraulic cylinder 405 at the top of the carriage 402 extends outwards, driving the center tip 406 to abut against the end face of the rotating shaft of the motor. At the same time, the tailstock 408 on the connecting seat 407 cooperates to clamp the motor rotating shaft. At this time, the motor rotating shaft can be effectively fixed. At the same time, the center position of the motor rotating shaft is placed on the four rotating wheels 703, with strong stability. Then, the third motor 409 rotates through the second pulley 410 on the output shaft. The second pulley 410 on the output shaft of the third motor 409 drives another second pulley 410 at the end of the tailstock 408 to rotate through the second belt 411. The second pulley 410 at this position drives the tailstock 408 and the motor rotating shaft to rotate, thus ensuring uniform grinding of the outer wall of the subsequent motor rotating shaft, improving the grinding effect. At the same time, by rotating the handle 404, the second lead screw 403 at the bottom of the carriage 402 can be driven to rotate. The second lead screw 403 can drive the carriage 402 to slide along the two third guide rails 401, thereby facilitating the rapid adjustment of the distance between the center tip 406 and the tailstock 408, and facilitating adaptation to motor rotating shafts of different lengths, with strong flexibility;

[0044] After the motor rotating shaft is fixed, it needs to be ground. At this time, the first motor 205 at the end of the mounting seat 201 drives the first lead screw 204 to rotate. The first lead screw 204 drives the sliding seat 203 to move horizontally along the two first guide rails 202, thereby facilitating the horizontal movement of the grinding wheel 302. At the same time, the first hydraulic cylinder 208 cooperates to drive the support seat 207 to move horizontally along the second guide rail 206, so as to achieve all-round grinding of the motor rotating shaft, with high operating efficiency. At this time, the second motor 303 drives the first pulley 304 on the output shaft to rotate. The first pulley 304 drives another first pulley 304 and the drive shaft 301 to rotate through the first belt 305. The drive shaft 301 drives the grinding wheel 302 to rotate and grind the surface of the motor rotating shaft, with high grinding efficiency.
