Description

Technical Field

[0001] The present invention relates to the technical field of intelligent welding systems, and specifically to an intelligent welding system for locomotive production. Background Art

[0002] Laser welding uses high-energy laser pulses to locally heat materials in a small area. The energy of laser radiation diffuses into the interior of the materials through heat conduction, melting the materials to form a specific molten pool. It is mainly used for welding thin-walled materials and precision parts, and can achieve spot welding, butt welding, and lap welding. It can be precisely controlled, with a small focused light spot, high positioning accuracy, and is easy to automate. Laser welding equipment is required during the welding process of the clutch housing and gears of a locomotive. The locomotive clutch housing and gears are fixed through a positioning tooling, and the positioning tooling is driven to rotate by a rotating assembly. A manipulator cooperates with a laser welding head to weld the locomotive clutch housing and gears.

[0003] However, the existing positioning tooling is a three-jaw chuck. The three-jaw chuck is installed on the rotating assembly, and positioning blocks are fixed on the clamping blocks of the three-jaw chuck. The positioning blocks on the three-jaw chuck are used to expand from the inner holes of the locomotive clutch housing and gears to fix the locomotive clutch housing and gears. During the use of the three-jaw chuck, it is necessary to repeatedly rotate a wrench to move the clamping blocks, resulting in low operation efficiency. Moreover, the contact force between the positioning block and the locomotive clutch housing is related to the number of turns of the wrench rotation, and the contact force between the positioning block and the locomotive clutch housing cannot be stably controlled. Since the three-jaw chuck needs to rotate, using an electric three-jaw chuck will increase the wiring difficulty;

[0004] To increase the operation efficiency, two positioning toolings can be set on the workbench. At this time, it is necessary for the manipulator to cooperate with the laser welding head to move, increasing the movement range of the manipulator. At the same time, during the alternating use of the two positioning toolings, the position of each operation is different, and the operator needs to move back and forth. Therefore, an intelligent welding system for locomotive production is needed to solve the above problems. Summary of the Invention

Specific embodiments

[0035] In order to make the technical means, creative features, achieved purposes and effects of the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0036] As Figure 1 and Figures 3 - 10 shown, an intelligent welding system for locomotive production according to the present invention includes a workbench 1 and a manipulator 11 on the workbench 1, and a laser welding head 12 on the manipulator 11 welds the locomotive clutch housing 9 and the gear 10; a first rotating part 2 for driving two support sleeves 3 to rotate is provided on the workbench 1; a second rotating part 5 is rotatably provided on the support sleeve 3, a transmission assembly 7 is provided on a support column 502 in the second rotating part 5, and the transmission assembly 7 drives the fixing tooling 8 to fix the locomotive clutch housing 9 and the gear 10.

[0037] There are two driving blocks 705 slidably connected to the support column 502. The fixing tooling 8 includes a slider 801 and a fixing column 802. The slider 801 is provided on the driving block 705, and two fixing columns 802 are fixed on the slider 801. A lead screw 804 is rotatably provided on the driving block 705. The lead screw 804 is threadedly connected to the slider 801. A through hole 503 is provided through the support column 502, and the through hole 503 is correspondingly arranged with the lead screw 804, which is convenient for engaging the lead screw 804 with an Allen wrench. According to the inner diameters of the locomotive clutch housing 9 and the gear 10, insert the Allen wrench through the through hole 503 to engage the Allen wrench with the lead screw 804. By rotating the lead screw 804, the lead screw 804 threadedly drives the slider 801 to slide on the slide bar 803, thereby changing the distance between the fixing columns 802 on the two opposite sliders 801, which is convenient for fixing the locomotive clutch housing 9 and the gear 10 with different inner diameters. A slide bar 803 is fixed on the driving block 705, and the slider 801 is slidably connected to the slide bar 803, making the sliding stability of the slider 801 better.

[0038] Specifically, as Figure 3 , Figure 5 and Figures 6 - 11 shown, a spring 707 is fixed between the driving block 705 and the support column 502, and the guide post 504 passes through the spring 707. Place the locomotive clutch housing 9 and the gear 10 on a fixing tooling 8 away from the laser welding head 12. At this time, the slide seat 701 is in the middle of the inclined surface 401, and the spring 707 stretches to drive the two driving blocks 705 to slide relative to each other. At this time, the diameter of the circle formed by the four fixing columns 802 on this fixing tooling 8 is smaller than the inner diameters of the locomotive clutch housing 9 and the gear 10, which is convenient for sleeving the locomotive clutch housing 9 and the gear 10 on the four fixing columns 802.

[0039] Specifically, as Figure 1 , Figure 2 and Figure 3 shown, the first rotating part 2 includes a rotating table 201. The rotating table 201 is rotatably provided on the workbench 1. Two support sleeves 3 are fixed on the rotating table 201. A connecting shaft 202 is fixed at the bottom end of the rotating table 201. A first driving part 203 is fixed on the linkage ring 4, and the first driving part 203 drives the connecting shaft 202 to rotate. When the locomotive clutch housing 9 and the gear 10 are placed, the first driving part 203 drives the connecting shaft 202 to rotate. The first driving part 203 is preferably a servo motor. The connecting shaft 202 drives the rotating table 201 to rotate with the workbench 1, and the support sleeves 3 on the workbench 1 drive the transmission assembly 7 to move.

[0040] Specifically, as Figure 3 , Figure 5 and Figures 8 - 10As shown, a linkage ring 4 is installed inside the workbench 1. An inclined surface 401 is provided on the linkage ring 4. The transmission assembly 7 includes a sliding seat 701 and a driving rod 703. Two symmetrically arranged sliding seats 701 are slidably provided on the linkage ring 4. The sliding seat 701 and the driving rod 703 are rotatably connected through a bearing. The driving rod 703 is slidably provided in each support column 502. Two sliding shafts 704 are fixed at the top of the driving rod 703. The sliding shafts 704 are slidably connected with the sliding grooves 706 on the driving block 705. A fixing tooling 8 is provided on the driving block 705. The support column 502 is a cylindrical structure with a T-shaped cross-section. The bottom end of the driving rod 703 is a cylinder, and the top end of the driving rod 703 is a cuboid structure; a rotatably connected roller 702 is provided on the sliding seat 701;

[0041] In the transmission assembly 7, the sliding seat 701 slides with the linkage ring 4, and the roller 702 on the sliding seat 701 rolls with the linkage ring 4, reducing the friction force and making it more convenient for the sliding seat 701 to move; when the sliding seat 701 is no longer in contact with the inclined surface 401, the sliding seat 701 slides onto the linkage ring 4, and the sliding seat 701 drives the driving rod 703 to slide upward, causing the driving rod 703 to slide with the support column 502. The two sliding shafts 704 on the driving rod 703 slide on the sliding grooves 706. The sliding grooves 706 are inclined, causing the sliding shafts 704 to drive the two driving blocks 705 to slide away from each other. The driving blocks 705 abut against the springs 707 and compress them, and the driving blocks 705 drive the fixing tooling 8 to move.

[0042] Specifically, as Figure 7 and Figure 11 shown, a guiding column 504 is fixed on the support column 502. The driving block 705 is slidably connected with the guiding column 504; during the movement of the driving block 705, it slides with the guiding column 504, thereby making the sliding of the driving block 705 more stable.

[0043] Specifically, as Figure 1 and Figures 2 - 5As shown in the figure, the driving assembly 6 includes a bearing block 603. A bearing block 603 and a second driving member 604 are fixed on the workbench 1. A driving shaft 602 is rotatably arranged on the bearing block 603. The second driving member 604 drives the driving shaft 602 to rotate. A driving wheel 601 is fixed on the driving shaft 602. The driving wheel 601 alternately drives two driven wheels 501 on the support column 502 to rotate; when the rotating table 201 rotates 180 degrees and then stops rotating, the two support sleeves 3 change positions. At this time, the sliding seat 701 in the front is in the middle of the inclined plane 401, and the spring 707 extends to drive the two driving blocks 705 to slide relatively. At this time, the diameter of the circle formed by the four fixing columns 802 on the fixing tooling 8 is smaller than the inner diameters of the locomotive clutch housing 9 and the gear 10, which is convenient for taking out the welded locomotive clutch housing 9 and gear 10. The manipulator 11 drives the laser welding head 12 to weld the fixed locomotive clutch housing 9 and gear 10. Since the driving wheel 601 is in contact with the driven wheel 501 at this time, the second driving member 604 drives the driving shaft 602 to rotate. The second driving member 604 is preferably a servo motor. The driving wheel 601 on the driving shaft 602 drives the driven wheel 501 to rotate, so that the support column 502 and the support sleeve 3 rotate, and the second rotating member 5 drives the fixing tooling 8 to rotate, so that the locomotive clutch housing 9 and the gear 10 rotate, making the welding more convenient. During the rotation of the support column 502, the driving rod 703 rotates with the sliding seat 701.

[0044] When the present invention is in use, the device is connected to the controller, then the power supply is turned on, and then according to the inner diameters of the locomotive clutch housing 9 and the gear 10, the hex key is inserted into the through hole 503 so that the hex key engages with the lead screw 804. By rotating the lead screw 804, the lead screw 804 threadedly drives the slider 801 to slide on the slide bar 803, thereby changing the distance between the fixing columns 802 on the two opposite sliders 801, which is convenient for fixing the locomotive clutch housing 9 and the gear 10 with different inner diameters;

[0045] The locomotive clutch housing 9 and the gear 10 are placed on a fixing tooling 8 facing away from the laser welding head 12. At this time, the sliding seat 701 is in the middle of the inclined plane 401, and the spring 707 extends to drive the two driving blocks 705 to slide relatively. At this time, the diameter of the circle formed by the four fixing columns 802 on the fixing tooling 8 is smaller than the inner diameters of the locomotive clutch housing 9 and the gear 10, which is convenient for sleeving the locomotive clutch housing 9 and the gear 10 on the four fixing columns 802;

[0046] After the locomotive clutch housing 9 and the gear 10 are placed, the first driving member 203 drives the connecting shaft 202 to rotate. The first driving member 203 is preferably a servo motor. The connecting shaft 202 drives the rotating table 201 and the workbench 1 to rotate. The support sleeve 3 on the workbench 1 drives the transmission assembly 7 to move. The slide block 701 in the transmission assembly 7 slides with the linkage ring 4. The roller 702 on the slide block 701 rolls with the linkage ring 4, reducing the friction force and making it more convenient for the slide block 701 to move. When the slide block 701 is no longer in contact with the inclined surface 401, the slide block 701 slides onto the linkage ring 4. The slide block 701 drives the driving rod 703 to slide upward, causing the driving rod 703 to slide with the support column 502. The two sliding shafts 704 on the driving rod 703 slide in the sliding groove 706. The sliding groove 706 is inclined, causing the sliding shafts 704 to drive the two driving blocks 705 to slide away from each other. The driving blocks 705 resist the spring 707 to compress. The driving blocks 705 drive the fixing tooling 8 to move, enabling the four fixing columns 802 on the fixing tooling 8 to quickly align with the locomotive clutch housing 9 and the gear 10, facilitating the quick disassembly and assembly of the locomotive clutch housing 9 and the gear 10, improving the operation efficiency. At the same time, the setting of the fixing tooling 8 facilitates the fixing of the locomotive clutch housing 9 and the gear 10 with different inner diameters. During the movement of the driving blocks 705, they slide with the guiding column 504, further enhancing the stability of the sliding of the driving blocks 705.

[0047] When the rotating table 201 rotates 180 degrees and then stops rotating, the two support sleeves 3 alternate positions. At this time, the slide block 701 in the front is in the middle of the inclined surface 401. The spring 707 extends to drive the two driving blocks 705 to slide relative to each other. At this time, the diameter of the circle formed by the four fixing columns 802 on the fixing tooling 8 is smaller than the inner diameter of the locomotive clutch housing 9 and the gear 10, facilitating the removal of the welded locomotive clutch housing 9 and gear 10. The manipulator 11 drives the laser welding head 12 to weld the fixed locomotive clutch housing 9 and gear 10. Since the driving wheel 601 is in contact with the driven wheel 501 at this time, the second driving member 604 drives the driving shaft 602 to rotate. The second driving member 604 is preferably a servo motor. The driving wheel 601 on the driving shaft 602 drives the driven wheel 501 to rotate, causing the support column 502 and the support sleeve 3 to rotate. The second rotating member 5 drives the fixing tooling 8 to rotate, enabling the locomotive clutch housing 9 and the gear 10 to rotate, making the welding more convenient. During the rotation of the support column 502, the driving rod 703 rotates with the slide block 701.
