Detailed Implementation

[0037] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0038] Example 1

[0039] Please see Figure 1 and Figure 2 As shown, the present invention is a grinding equipment for automotive drive shafts based on intelligent automotive manufacturing, including a workbench 2, on which a positioning module for positioning an automotive drive shaft 1 is provided; specifically, in this embodiment, the automotive drive shaft 1 is made of carbon steel, and the two ends of the automotive drive shaft 1 are symmetrically arranged with connecting parts for assembling universal joints, wherein the connecting part includes a U-shaped support 101 fixed to the end of the automotive drive shaft 1, and a pin 102 is rotatably arranged in the U-shaped support 101, and a pin hole 103 is opened on the pin 102;

[0040] Please see Figure 2 and Figure 3 The workbench 2 is also equipped with a grinding box 5. The grinding box 5 has symmetrically opened U-shaped grooves 502 on both sides for embedding the car drive shaft 1. Two sets of limiting plates 501 are symmetrically fixed on the side of the grinding box 5 facing the U-shaped groove 502, and a gap is formed between the two sets of limiting plates 501 for communicating with the U-shaped groove 502.

[0041] Please see Figure 4 A grinding roller 613 is rotatably arranged on one side of the grinding box 5 toward the U-shaped groove 502. The grinding roller 613 is fixed to the output end of the drive motor 509 which is fixedly arranged on the outside of the grinding box 5.

[0042] Specifically, when grinding the car drive shaft 1, the shaft body of the car drive shaft 1 is first inserted into the U-shaped groove 502 through the gap, and then positioned by the positioning module. After positioning, the drive motor 509 is started to drive the grinding roller 613 to rotate. During the rotation of the grinding roller 613, the shaft body of the car drive shaft 1 is ground. During the grinding process, since the car drive shaft 1 is embedded in the grinding box 5 at the grinding part, the generated metal shavings can be temporarily stored in the grinding box 5, and will not fly around, which is safer and easier to collect.

[0043] It also includes an adjustment unit and a drive unit. The adjustment unit is used to drive the positioned car drive shaft 1 to rotate, and the drive unit is used to drive the grinding box 5 to move along the axial direction of the car drive shaft 1. It can be explained that when the car drive shaft 1 is being ground, the adjustment unit drives the car drive shaft 1 to rotate in real time so that all angles of the car drive shaft 1 are effectively ground. Correspondingly, after any section of the shaft is ground, the drive unit drives the grinding box 5 to move along the axial direction of the car drive shaft 1 to fully grind the entire shaft. This embodiment does not require manual adjustment of the angle and position of the car drive shaft 1, resulting in higher grinding efficiency and higher safety.

[0044] Example 2

[0045] Based on Example 1, please refer to Figure 2 At Figure 5 The positioning module includes two sets of symmetrical positioning plates 402. A lead screw 403 is rotatably mounted on one side of the two sets of positioning plates 402 that are close to each other. The threads on both sides of the lead screw 403 have opposite directions. A first nut 404 is symmetrically spirally sleeved on the lead screw 403. A positioning frame 405 is fixedly mounted on the first nut 404. A positioning shaft 406 for engaging with the pin hole 103 is fixedly mounted at one end of the two positioning frames 405 that are close to each other. Specifically, in this embodiment, the end of the lead screw 403 is provided with a handle. When positioning the car drive shaft 1, the pins 102 at both ends of the car drive shaft 1 are first placed between the two sets of positioning frames 405. Then, the lead screw 403 is rotated. During the movement of the first nut 404 on the lead screw 403, the positioning frame 405 drives the positioning shaft 406 to engage with the pin hole 103, thereby realizing the positioning of the car drive shaft 1.

[0046] It should be noted that the handle in this embodiment can be replaced by a servo motor to further improve the automation level of the positioning module, and there is no limitation on this.

[0047] As a further solution in this embodiment, please refer to Figure 2 The workbench 2 is also fixedly equipped with a first drive housing 4, in which a screw is rotatably arranged. The screw is fixed to the drive end of a servo motor fixed on the outside of the first drive housing 4. The threads on both sides of the screw have opposite directions. A second nut is symmetrically spirally sleeved on the screw. The second nut is fixed to a limiting frame 401. The ends of the positioning plates 402 on both sides that are far apart are fixed to a support rod 303. The support rod 303 is rotatably connected to the limiting frame 401. It can be explained that in this embodiment, the screw is driven to rotate by a servo motor. During the movement of the second nuts on both sides on the screw, the limiting frame 401 drives the support rods 303 on both sides and the positioning plates 402 to move closer or further apart, so as to facilitate the positioning of automotive drive shafts 1 of different lengths.

[0048] Please see Figure 2 and Figure 6 The adjustment unit includes two sets of support frames 204 symmetrically fixed on the workbench 2. Sleeves 3 are rotatably mounted on the support frames 204. Support rods 303 are slidably inserted into one side of the sleeves 3. Several sets of strip-shaped slots 305 are arranged in a circumferential array on the inner wall of the sleeves 3. Several sets of strip-shaped retainers 304, corresponding to and slidably engaging with the strip-shaped slots 305, are fixedly mounted on the support rods 303. A first gear 301 is fixedly mounted at the far end of the two sets of sleeves 3. A drive cylinder 6 is fixedly mounted on one side of the workbench 2, and a connecting frame 601 is fixedly mounted at the drive end of the drive cylinder 6, connecting... The frame 601 has a first rack 302 fixedly arranged symmetrically at both ends, which meshes with the first gear 301. It can be explained that when adjusting the grinding angle of the car drive shaft 1, the drive cylinder 6 is activated to drive the connecting frame 601 to move on the worktable 2. During the movement, the connecting frame 601 drives the first gear 301 to rotate through the first rack 302. The first gear 301 drives the sleeve 3 to rotate, and at the same time, it drives the positioning plate 402 to rotate through the strip-shaped card seat 304 and the strip-shaped card groove 305. In this way, the angle of the car drive shaft 1 can be adjusted to achieve sufficient grinding.

[0049] In this embodiment, to prevent metal shavings generated during polishing from flying out through the gap between the two sets of limiting plates 501, please refer to the relevant documentation. Figures 3-4 Both sets of limiting plates 501 have sliding grooves 510, and sealing plates 511 are slidably arranged in the sliding grooves 510. Conical plates 503 are fixedly arranged on the side of the two sets of sealing plates 511 that are close to each other. Guide grooves 504 are formed on both sides of the sliding grooves 510. The two ends of the sealing plates 511 are fixed to the supports 505 through the guide grooves 504 via connecting rods. Guide plates 506 are symmetrically fixed on both sides of the limiting plates 501. Guide rods 507, fixed to the supports 505, are slidably arranged between the guide plates 506. A first spring 508 is provided on the guide rod 507. Specifically, one end of the first spring 508 is fixed to the support 505, and the other end is fixed to the guide plate 506. It can be noted that in the initial state, the two conical plates... The 503 plates fit together to seal the gap. When positioning the car drive shaft 1, the shaft of the car drive shaft 1 abuts against the tapered plates 503 on both sides. Since both sides of the tapered plates 503 are inclined surfaces, the sealing plate 511 can be pushed to retract towards the inside of the slide groove 510 under the action of abutment. The sealing plate 511 drives the guide rod 507 to slide in the guide plate 506 through the support 505 to compress the first spring 508. When the car drive shaft 1 is fully embedded in the U-shaped groove 502, the sealing plate 511 and the tapered plate 503 can be reset under the elastic force of the first spring 508, and the gap is resealed, so that the metal chips generated during the grinding process will not splash out from the gap, and the sealing performance is better.

[0050] For further details, please refer to Figure 2The workbench 2 is also slidably equipped with a base plate 202, and a second drive housing 203 is fixedly mounted on the base plate 202. The second drive housing 203 is equipped with a synchronous belt mechanism for driving the grinding housing 5 to move along the axis perpendicular to the automobile drive shaft 1. Specifically, after the automobile drive shaft 1 is positioned by the positioning module, the synchronous belt mechanism in the second drive housing 203 drives the grinding housing 5 to move toward the automobile drive shaft 1 so as to embed the automobile drive shaft 1 into the U-shaped groove 502.

[0051] Please see Figure 2 The drive unit includes a third drive housing 201 fixedly mounted on the worktable 2. The third drive housing 201 is provided with a synchronous belt mechanism for driving the grinding housing 5 to move along the axis of the automobile drive shaft 1. It can be explained that during the grinding process, the synchronous belt mechanism in the third drive housing 201 drives the grinding housing 5 to move along the axial direction of the automobile drive shaft 1 to grind the entire shaft of the automobile drive shaft 1.

[0052] Please see Figures 3-4 as well as Figure 7 The bottom of the grinding chamber 5 is equipped with several sets of support shafts 610 arranged at equal intervals. Two sets of electromagnetic rods 609 are symmetrically fixed on the support shafts 610. First electrode plates 612 are symmetrically fixed at both ends of the support shafts 610. A sealing baffle 602 is slidably arranged at the open end of the bottom of the grinding chamber 5. The sealing baffle 602 is connected to a pusher that drives it to move horizontally along the open end. Several sets of L-shaped baffles 608 are arranged on both sides of the sealing baffle 602. Second electrode plates 611 for electrical connection with the first electrode plates 612 are fixedly arranged on the L-shaped baffles 608. It can be noted that in the initial state, the sealing baffle 602 is in the position of the grinding chamber. The bottom opening of the grinding chamber 5 is sealed. At this time, the first electrode plate 612 and the second electrode plate 611 are attached and electrically connected. An external power supply can supply power to the electromagnetic rod 609 through the first electrode plate 612 and the second electrode plate 611 to generate magnetic force. Therefore, when grinding the car drive shaft 1, metal debris can be attracted by the electromagnetic rod 609. After grinding is completed, the sealing baffle 602 is pushed to one side of the opening by the pushing part. At this time, the first electrode plate 612 and the second electrode plate 611 separate synchronously, the electromagnetic rod 609 loses its magnetism, and the metal debris on its surface can be discharged from the opening and collected uniformly.

[0053] In this embodiment, please refer to Figure 2 and Figure 3 as well as Figure 7The driving unit includes two sets of limiting rods 604 symmetrically fixedly arranged on the outside of the grinding box 5. The ends of the two sets of limiting rods 604 are fixed to the support plate 606. A movable plate 603 fixed to the sealing baffle 602 is slidably arranged on the limiting rods 604. A second spring 605 is provided on the limiting rods 604. One end of the second spring 605 is fixed to the support plate 606, and the other end is fixed to the movable plate 603. The two ends of the support shaft 610 are symmetrically fixedly arranged with second gears 607. Two sets of second racks 207 for meshing with the second gears 607 are symmetrically fixedly arranged on the bottom plate 202. Through grooves 205 are opened on the bottom plates 202 on both sides of the second drive box 203. The through grooves 205 are connected to the collection box 206 fixedly arranged at the bottom of the bottom plate 202. It can be noted that after grinding is completed... The synchronous belt mechanism in the second drive housing 203 drives the grinding housing 5 to move away from the car drive shaft 1. The second racks 207 on both sides abut against the L-shaped baffles 608 to restrict its movement. At this time, the first electrode plate 612 and the second electrode plate 611 separate, and the metal debris adsorbed on the surface of the electromagnetic rod 609 can fall synchronously and fall into the collection box 206 through the through groove 205. During the movement of the grinding housing 5, each second gear 607 meshes with the second rack 207 to drive the support shaft 610 and the electromagnetic rod 609 to rotate, so that the metal debris adsorbed at all angles on the surface of the electromagnetic rod 609 falls into the collection box 206. After the metal debris is collected, as the grinding housing 5 resets, the second spring 605 can drive the sealing baffle 602 to reset to the open end.

[0054] A grinding method for automotive driveshaft grinding equipment based on intelligent automotive manufacturing includes the following steps:

[0055] The pins 102 at both ends of the car drive shaft 1 are placed between the two sets of positioning frames 405. Then, the lead screw 403 is rotated. During the movement of the first nut 404 on the lead screw 403, the positioning frame 405 drives the positioning shaft 406 to be inserted into the pin hole 103 to position the car drive shaft 1.

[0056] The synchronous belt mechanism in the second drive housing 203 drives the grinding housing 5 to move toward the car drive shaft 1 so as to embed the car drive shaft 1 into the U-shaped groove 502.

[0057] Start the drive motor 509 to drive the grinding roller 613 to rotate. During the rotation, the grinding roller 613 grinds the shaft of the automobile drive shaft 1.

[0058] The start-up drive cylinder 6 drives the connecting frame 601 to move on the worktable 2. During the movement, the connecting frame 601 drives the first gear 301 to rotate through the first rack 302. The first gear 301 drives the sleeve 3 to rotate, and at the same time, it drives the positioning plate 402 to rotate through the strip-shaped card seat 304 and the strip-shaped card slot 305 to adjust the angle of the car drive shaft 1.

[0059] The synchronous belt mechanism in the third drive housing 201 drives the grinding housing 5 to move along the axial direction of the automobile drive shaft 1 in order to grind the entire shaft of the automobile drive shaft 1.
