Description

Technical Field

[0001] This invention relates to the field of transmission shaft processing equipment technology, specifically to an automotive transmission shaft processing equipment. Background Technology

[0002] A driveshaft is a high-speed, low-support rotating body, a crucial mechanical component in vehicles, that transmits power from the engine to the wheels, enabling the vehicle to move. It is primarily composed of small parts such as the shaft tube, telescopic sleeve, and universal joint. It can rotate in different directions and can connect or separate from other parts, flexibly distributing the energy produced by the engine. During manufacturing, the driveshaft is typically welded to the driveshaft fork using machining equipment.

[0003] However, when welding the drive shaft to the drive shaft fork, the drive shaft is usually placed on a bracket on the base. The bracket is usually assembled with bolts. When encountering drive shafts of different diameters, it is not convenient to quickly adjust the height of the bracket, resulting in low adjustment efficiency. At the same time, after the operator places the drive shaft on the bracket and fixes it with the connecting posts on both sides, due to the different placement positions, one of the connecting posts will collide with the drive shaft fork during fixation. When the drive shaft slides between the drive shaft and the bracket, it may cause the drive shaft to shift, affecting the welding quality. In addition, a large number of sparks are generated during the welding process, and the spark splatter range is large. Each time the welding effect needs to be observed, the welding protective cover needs to be repeatedly removed for observation. Summary of the Invention

[0041] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0042] like Figures 1-16 As shown, the automotive drive shaft processing equipment of the present invention includes a base 1; two slides 2 mounted on the base 1; and a support structure 4, which is provided on the base 1. The support structure 4 includes a support rod 401, which is slidably connected to the base 1. An mounting rod 402 is slidably connected to the support rod 401, and two support wheels 403 are rotatably connected to the mounting rod 402. A first lead screw 404 is rotatably connected to the base 1, and the first lead screw 404 is threadedly connected to the support rod 401. A worm gear 405 is fixedly connected to a lead screw 404. The worm gear 405 meshes with a worm 406. The worm 406 is rotatably connected to a base 1. Both the support rod 401 and the mounting rod 402 are provided with scale bars 9. The support rod 401 and the mounting rod 402 are fixed together by a limiting structure 5. The limiting structure 5 includes a limiting block 501; a fixing structure 6, which is provided on the base 1; a welding structure 7, which is provided on the fixing structure 6; and a protective structure 8, which is provided on the welding structure 7.

[0043] Specifically, a handwheel 407 is fixedly connected to the worm gear 406, a limit block 501 is slidably connected to the support rod 401, the limit block 501 engages with one of the limit grooves 502 on the mounting rod 402, the mounting rod 402 has multiple limit grooves 502, a connecting plate 503 is fixedly connected to the limit block 501, the connecting plate 503 is slidably connected to the support rod 401, a first return spring 504 is fixedly connected to the connecting plate 503 and the support rod 401, and the limit block 501... The end section facing the mounting rod 402 has a trapezoidal structure. When the position of the support wheel 403 needs to be adjusted according to the drive shaft of different diameters, when the mounting rod 402 is pulled upward, because the end section of the limiting block 501 facing the mounting rod 402 has a trapezoidal structure, the mounting rod 402 will abut against the edge of the limiting block 501, causing the limiting block 501 to slide against the support rod 401. When the limiting block 501 slides, it will drive the connecting plate 503 to slide. When the connecting plate 503 slides, the first return spring 504 will contract, and at the same time, the mounting rod 402 will slide. 2. The rod can slide upwards continuously. While sliding, the scale bar 9 on the rod 402 can be observed to determine the sliding distance between the rod 402 and the support rod 401. When it slides to a certain position, the limiting block 501 engages with the limiting groove 502 on the rod 402 under the action of the first return spring 504. This completes the coarse adjustment of the support wheel 403's position. At this point, the worm gear 406 can be rotated via the handwheel 407. The rotation of the worm gear 406 will drive the worm wheel 405 to rotate, which in turn drives the first lead screw 401. 4. When the first lead screw 404 rotates, it will drive the support rod 401 to slide, causing the support rod 401 to slide between the base 1 and the base. When the support rod 401 slides, the sliding distance between the scale bar 9 on the support rod 401 and the base 1 can be observed. At this time, the support rod 401 is driven up and down on the base 1 by the first lead screw 404 to make precise adjustments. This is convenient for adjustment in conjunction with the mounting rod 402 after coarse adjustment, which improves the adjustment efficiency and accuracy, so that the axis of the transmission shaft of different diameters is located at the center of the connecting column 301.

[0044] Specifically, the fixing structure 6 includes a vertical rod 601, which is fixedly connected to the base 1. A mounting block 604 is slidably connected to the vertical rod 601, and a fixed wheel 605 is rotatably connected to the mounting block 604. A second hydraulic rod 602 is mounted on the vertical rod 601, and a sliding rod 603 is fixedly connected to the telescopic end of the second hydraulic rod 602. The sliding rod 603 is fixedly connected to the mounting block 604. First, the operator inserts the drive shaft fork into the drive shaft for initial positioning. Then, the drive shaft fork is mounted... The drive shaft of the pivot fork is placed on two support wheels 403. Then, by actuating the second hydraulic rod 602 on the upright 601, when the telescopic end of the second hydraulic rod 602 retracts, it will drive the slide rod 603 to move downward. When the slide rod 603 moves downward, it will drive the mounting block 604 to slide downward. When the mounting block 604 slides downward, it will drive the fixed wheel 605 to move downward, so that the fixed wheel 605 cooperates with the two support wheels 403 to fix the drive shaft, preventing the drive shaft from falling off the support wheels 403. At the same time, the three wheels make the rotation of the drive shaft more stable.

[0045] Specifically, the welding structure 7 includes an adjusting rod 701. Two adjusting rods 701 are slidably connected to the upright 601. A fixing rod 705 is slidably connected to the adjusting rod 701. A welding gun 710 is mounted on the fixing rod 705. A limiting rod 706 is slidably connected to the fixing rod 705. The limiting rod 706 engages with one of the limiting holes 707 on the adjusting rod 701. A rubber pad 702 is slidably connected to the fixing rod 705. The rubber pad 702 abuts against the upright 601. A mounting plate 703 is fixedly connected to the rubber pad 702. The mounting plate 703 is slidably connected to the adjusting rod 701. A second screw is rotatably connected to the adjusting rod 701. The second lead screw 704 is threadedly connected to the mounting plate 703. A pressing plate 709 is fixedly connected to the limiting rod 706, and the pressing plate 709 is slidably connected to the fixing rod 705. A second return spring 708 is fixedly connected to the limiting rod 706 and the fixing rod 705. The adjusting rod 701 is provided with multiple limiting holes 707 that cooperate with the limiting rod 706. When it is necessary to adjust the position of the welding gun 710, it can slide on the upright rod 601 through the two adjusting rods 701. When the adjusting rods 701 move, they will drive the welding gun 710 to move through the fixing rod 705. When the adjusting rods 701 slide to a certain position, an internal hex wrench is inserted into the second lead screw. In the hexagonal groove on 704, the second lead screw 704 is rotated by an internal hexagonal wrench, causing the second lead screw 704 to drive the mounting plate 703 to slide. When the mounting plate 703 slides, it will cause the rubber pad 702 to abut against the upright 601. The adjusting rod 701 is slidably connected to the upright 601, which facilitates quick adjustment of the position of the welding gun 710 according to different welding positions. The second lead screw 704 drives the rubber pad 702 to abut against the upright 601, which facilitates fixing the adjusted rod 701 after sliding. At this time, the pressing plate 709 can be pressed. When the pressing plate 709 slides down, it will drive the limiting rod 706 to move down. When the limiting rod 706 moves down, the second return spring 70... 8. When the rod contracts, the limiting rod 706 is no longer engaged with the limiting hole 707 on the adjusting rod 701. At this time, the fixing rod 705 can slide back and forth on the adjusting rod 701. When the fixing rod 705 slides to a certain position, the pressing plate 709 is released, so that the fixing rod 705 engages with another limiting hole 707 on the adjusting rod 701 under the action of the second return spring 708. The back and forth sliding between the fixing rod 705 and the adjusting rod 701 makes it easy to adjust the back and forth position of the welding gun 710 according to the different diameter drive shafts, which improves the welding quality. At the same time, the engagement between the limiting rod 706 and the multiple limiting holes 707 on the adjusting rod 701 makes it easy to fix the adjusted fixing rod 705.

[0046] Specifically, the protective structure 8 includes a first protective frame 801, with the first protective frame 801 fixedly connected to the two adjusting rods 701. A second protective frame 802 is rotatably connected to the two first protective frames 801. A transparent protective plate 803 is installed between each of the second protective frames 802 and the first protective frame 801. A fixing block 804 is slidably connected to each of the two second protective frames 802. The fixing block 804 engages with a fixing groove 805 on the first protective frame 801. A pull rod 807 is fixedly connected to the fixing block 804, and the pull rod 807 is slidably connected to the second protective frame 802. The fixing block 804 is fixed to the second protective frame 802. A third return spring 806 is connected. Before welding, the pull rods 807 on the two second protective frames 802 can be pulled. When the pull rods 807 slide, they will drive the fixing block 804 to slide, so that the fixing block 804 is away from the fixing groove 805 on the first protective frame 801. The fixing block 804 slides until the third return spring 806 retracts, and at the same time, the fixing block 804 is no longer locked with the fixing groove 805. At this time, the second protective frame 802 can be rotated down. The transparent protective plates 803 on the two protective frames will block the sparks generated during welding, reducing the range of spark splash. This allows the operator to observe the welding effect through the transparent protective plates 803 in front of the base 1, improving safety.

[0047] Specifically, the slide block 2 is provided with a rotating structure 3, which includes a connecting column 301. The two slide blocks 2 are rotatably connected to the connecting column 301. A mounting base 302 is slidably connected to the slide block 2. The connecting column 301 and the mounting base 302 are rotatably connected. A first hydraulic rod 305 is mounted on the slide block 2. The telescopic end of the first hydraulic rod 305 is fixedly connected to a connecting rod 304. The connecting rod 304 is fixedly connected to the mounting base 302. A motor 303 is mounted on the mounting base 302 of the left slide block 2. The connecting column 301 on the left side is fixedly connected to the output shaft of the motor 303. At this time, by activating the first hydraulic rod 305 on the two slide blocks 2, when the telescopic end of the first hydraulic rod 305 retracts, it will drive the mounting base 302 to slide via the connecting rod 304, causing the mounting base 302 to drive the connecting column 301 to slide. This causes the two connecting columns 301 to move towards the transmission shaft forks at both ends of the transmission shaft, thus enabling the two... The connecting column 301 secures the drive shaft fork. At this time, the motor 303 on the left mounting base 302 can be started. When the output shaft of the motor 303 rotates, it drives the connecting column 301 on the left to rotate, causing the drive shaft fork and drive shaft to rotate. During rotation, the connection between the drive shaft fork and drive shaft can be welded using the welding gun 710. After the drive shaft and drive shaft fork are secured by the two connecting columns 301, rotation facilitates welding of the drive shaft and drive shaft fork with the welding gun 710. When encountering drive shafts of different lengths, the positions of the two slides 2 on the base 1 can be adjusted. Simultaneously, the two first hydraulic rods 305 retract by the same distance each time, facilitating contact positioning at both ends of each type of drive shaft. This ensures that the welding position of the same type of drive shaft is consistent. When welding the same type of drive shaft, there is no need to adjust the position of the welding gun 710, improving operational flexibility.

[0048] In use, the operator first inserts the drive shaft fork into the drive shaft for initial positioning. Then, the drive shaft with the drive shaft fork is placed on two support wheels 403. The second hydraulic rod 602 on the upright 601 is then activated. When the telescopic end of the second hydraulic rod 602 retracts, it drives the sliding rod 603 downward. When the sliding rod 603 moves downward, it drives the mounting block 604 downward. When the mounting block 604 slides downward, it drives the fixed wheel 605 downward. The fixed wheel 605, together with the two support wheels 403, fixes the drive shaft, preventing it from falling off the support wheels 403. At the same time, the three wheels make the drive shaft rotate more smoothly.

[0049] When the position of the support wheel 403 needs to be adjusted according to the drive shafts of different diameters, when the mounting rod 402 is pulled upward, the end section of the limiting block 501 facing the mounting rod 402 is trapezoidal, so the mounting rod 402 will abut against the edge of the limiting block 501, causing the limiting block 501 to slide against the support rod 401. When the limiting block 501 slides, it will drive the connecting plate 503 to slide. When the connecting plate 503 slides, the first return spring 504 will contract. At the same time, the mounting rod 402 can continue to slide upward. When the mounting rod 402 slides, the scale bar 9 on the mounting rod 402 can be observed to see the sliding distance between the mounting rod 402 and the support rod 401. When it slides to a certain position, the limiting block 501, under the action of the first return spring 504, will contact the limiting block on the mounting rod 402. When the grooves 502 are engaged, the coarse adjustment of the position of the support wheel 403 is completed. At this time, the worm 406 can be rotated by the handwheel 407. When the worm 406 rotates, it will drive the worm wheel 405 to rotate. When the worm wheel 405 rotates, it will drive the first lead screw 404 to rotate. When the first lead screw 404 rotates, it will drive the support rod 401 to slide, so that the support rod 401 slides between the base 1. When the support rod 401 slides, the sliding distance between the scale strip 9 on the support rod 401 and the base 1 can be observed. At this time, the support rod 401 is driven up and down on the base 1 by the first lead screw 404 to make precise adjustment. This is convenient for adjustment with the mounting rod 402 after coarse adjustment, which improves the adjustment efficiency and accuracy, so that the axis of the drive shaft of different diameters is located at the center of the connecting column 301.

[0050] At this time, the first hydraulic rods 305 on the two slide blocks 2 can be activated. When the telescopic ends of the first hydraulic rods 305 retract, they will drive the mounting base 302 to slide through the connecting rod 304, causing the mounting base 302 to drive the connecting column 301 to slide. This causes the two connecting columns 301 to move towards the drive shaft forks at both ends of the drive shaft, thus securing the two connecting columns 301 against the drive shaft forks. At this time, the motor 303 on the left mounting base 302 can be activated. When the output shaft of the motor 303 rotates, it will drive the left connecting column 301 to rotate, causing the left connecting column 301 to drive the drive shaft forks and the drive shaft to rotate. During rotation, the welding gun 710 can be used to... Welding is performed at the connection between the drive shaft fork and the drive shaft. After the drive shaft and the drive shaft fork are fixed by two connecting columns 301, they are rotated to facilitate welding with the welding gun 710. When encountering drive shafts of different lengths, the positions of the two slides 2 on the base 1 can be adjusted. At the same time, the two first hydraulic rods 305 retract by the same distance each time, so as to make the two ends of each type of drive shaft contact and position, so that the welding position of the same type of drive shaft is the same. When welding the same type of drive shaft, there is no need to adjust the position of the welding gun 710, which improves the operational flexibility.

[0051] Before welding, the pull rods 807 on the two second protective frames 802 can be pulled. When the pull rods 807 slide, they will drive the fixing block 804 to slide, so that the fixing block 804 is away from the fixing groove 805 on the first protective frame 801. The fixing block 804 slides until the third return spring 806 retracts, and at the same time, the fixing block 804 is no longer locked with the fixing groove 805. At this time, the second protective frame 802 can be rotated down. The transparent protective plates 803 on the two protective frames will block the sparks generated during welding, reducing the range of spark splash. This allows the operator to observe the welding effect through the transparent protective plates 803 in front of the base 1, improving safety.

[0052] When the position of the welding gun 710 needs to be adjusted, it can be slid on the upright 601 via two adjusting rods 701. The movement of the adjusting rods 701 drives the welding gun 710 via the fixed rod 705. When the adjusting rods 701 slide to a certain position, an internal hex wrench is inserted into the hexagonal groove on the second lead screw 704. Rotating the second lead screw 704 with the internal hex wrench causes the threaded drive of the second lead screw 704 to slide the mounting plate 703. The sliding of the mounting plate 703 causes the rubber pad 702 to press against the upright 601. This sliding connection between the adjusting rods 701 and the upright 601 facilitates quick adjustment of the welding gun 710's position according to different welding locations. Furthermore, the threaded drive of the second lead screw 704 to press against the rubber pad 702 facilitates fixing the slidable adjusting rod 701. At this point, the position can be fixed by pressing the... When the pressure plate 709 slides downward, it drives the limiting rod 706 to move downward. When the limiting rod 706 moves downward, the second return spring 708 retracts, and at the same time, the limiting rod 706 is no longer engaged with the limiting hole 707 on the adjusting rod 701. At this time, the fixing rod 705 can slide back and forth on the adjusting rod 701. When the fixing rod 705 slides to a certain position, the pressure plate 709 is released, so that the fixing rod 705 engages with another limiting hole 707 on the adjusting rod 701 under the action of the second return spring 708. By sliding back and forth between the fixing rod 705 and the adjusting rod 701, it is convenient to adjust the back and forth position of the welding gun 710 according to the different diameter drive shafts, which improves the welding quality. At the same time, by engaging the limiting rod 706 with the multiple limiting holes 707 on the adjusting rod 701, it is convenient to fix the adjusted fixing rod 705.
