Description

Technical Field

[0001] This application relates to the technical field of welding, and in particular to an auxiliary device for welding frame pins. Background Technology

[0002] Welding auxiliary devices are increasingly widely used in modern welding production, and their benefits are comprehensive, mainly reflected in the following aspects: significantly improving welding quality and consistency; greatly increasing production efficiency by reducing auxiliary time and enabling continuous welding; effectively improving working conditions and ensuring operational safety; and enhancing process adaptability and flexibility. In summary, welding auxiliary devices are the cornerstone of modern efficient and high-quality welding production.

[0003] Frame pins are primarily used as positioning components to determine the relative positions of parts; they can also serve as connectors, transmitting lateral forces or torques; or as overload cut-off components in safety devices. Frame pins are typically machined by welding.

[0004] With the increasing level of industrial automation, the requirements for welding precision and efficiency are also becoming higher. Although welding auxiliary devices on the market are usually equipped with external control systems (such as PLCs or industrial computers) for parameter setting and motion coordination, they mostly suffer from poor versatility and cumbersome adjustments. Even with the reliance on these external control systems, the structure and tooling design of the devices themselves are often difficult to adapt quickly and conveniently to the welding needs of different specifications of frame pins, resulting in low switching efficiency and difficulty in meeting the flexibility and diversity requirements of modern production. Utility Model Content

[0005] To address the problem that welding auxiliary devices cannot meet the welding requirements of frame pins of different specifications, this application provides a frame pin welding auxiliary device.

[0006] The frame pin welding auxiliary device provided in this application adopts the following technical solution:

[0008] By adopting the above technical solution, the clamping plate is provided with several positioning blocks. The clamping plate places the workpiece on the positioning blocks. After the workpiece is placed on the positioning blocks on the clamping plate, the pushing component pushes the workpiece towards the clamping component. Subsequently, the clamping component positions the workpiece on the clamping plate. By pushing several workpieces, the ends of several workpieces are aligned to facilitate subsequent welding by the welding robot. The clamping plate is provided with V-shaped blocks for placing workpieces, and the clamping end of the clamping component for the workpiece is also a V-shaped block, which facilitates clamping workpieces of different diameters.

[0009] Preferably, the pushing assembly includes a pushing motor, a connecting shaft, a screw, and a pushing plate. The pushing motor, connecting shaft, screw, and pushing plate are all connected to the clamping plate.

[0010] By adopting the above technical solution, the drive motor drives the screw to rotate through the connecting shaft. The screw is threadedly connected to the push plate. When the screw rotates, the push plate moves along the axis of the screw on the clamping plate, thereby pushing the workpiece towards the clamping assembly. The push plate is L-shaped, with the horizontal plate on the push plate connected to the screw and the vertical plate on the push plate used to push the workpiece.

[0011] Preferably, the clamping assembly includes a first support column, a second support column, a clamping beam, a positioning element, and a clamping element. The first support column and the second support column are both connected to the clamping plate, and the ends of the first support column and the second support column are connected to the clamping beam. The positioning element is connected to one end of the clamping beam and is used to position the clamping beam on the second support column. The clamping element is connected to the clamping beam and is used to position the workpiece on the positioning block of the clamping plate.

The positioning support block is connected to the end of the clamping beam, the positioning rod is slidably connected to the positioning support block, the positioning rod is provided with a connecting piece, the positioning spring is sleeved on the positioning rod, one end of the positioning spring abuts against the positioning support block, and the other end of the positioning spring abuts against the connecting piece; the end of the positioning rod extends into the second support column, and the positioning rod is used to position the clamping beam on the second support column.

[0014] By adopting the above technical solution, one end of the clamping beam is rotatably connected to the first support column, and the other end of the clamping beam is positioned on the clamping beam by a positioning component. The clamping beam is positioned on the second support column by a positioning rod, and the end of the positioning rod is positioned on the second support column by a positioning spring, thereby ensuring that the clamping beam is stably positioned on the second support column.

[0015] Preferably, the clamping component includes a clamping rod, a clamping block, and a clamping screw. The clamping rod is slidably connected to the clamping beam, and the clamping block is connected to the clamping rod. The clamping block is used to clamp the workpiece onto the positioning block. The clamping screw is located between the clamping rod and the clamping beam, and the clamping screw connects the clamping rod to the clamping beam. The clamping screw is used to drive the clamping rod to slide on the clamping beam.

[0016] By adopting the above technical solution, when the clamping screw rotates in the forward direction, the clamping rod drives the clamping block to move closer to the positioning block, thereby clamping the workpiece on the positioning block; when the clamping screw rotates in the reverse direction, the clamping rod drives the clamping block to move away from the positioning block, thereby removing the workpiece from the positioning block.

After the staff climbs onto the control platform via the connecting ladder, they input the commands to control the welding robot and the positioning mechanism on the control panel on the column. Subsequently, the welding robot and the positioning mechanism work according to the commands. The advantage of setting the control platform at a higher position is that when the welding robot and the positioning mechanism work according to the input commands, the staff can observe the working situation of the welding robot and the positioning mechanism more comprehensively when they climb onto the control platform.

The pushing plate pushes several workpieces, thereby aligning the ends of several workpieces to facilitate subsequent welding by the welding robot. The clamping plate is equipped with V-shaped blocks for placing workpieces, and the clamping end of the clamping component for the workpiece is also a V-shaped block, which facilitates the clamping of workpieces of different diameters.

Detailed Implementation

[0038] The following is in conjunction with the appendix Figure 1-9 This application will be described in further detail.

[0039] This application discloses an auxiliary device for welding vehicle frame pins, referring to... Figure 1The system includes a base 1, a welding robot 4, and a positioning mechanism 5. A column 2 is vertically fixed to the base 1, and a control platform 21 is fixedly connected to the column 2. A connecting ladder 23 is provided on one side of the control platform 21. A control panel 22 is located on the side of the column 2 facing the control platform 21. A crossbeam 3 is fixedly connected to the upper end of the column 2, with its long axis perpendicular to the long axis of the column 2. One end of the crossbeam 3 is fixedly connected to the upper end of the column 2, and the welding robot 4 is mounted on the other end of the crossbeam 3. A positioning mechanism 5 is located below the welding robot 4 and is mounted on the base 1. The positioning mechanism 5 is used to mount a workpiece 6, and the welding robot 4 is used to weld the workpiece 6 mounted on the positioning mechanism 5. The control panel 22 is connected to the welding robot 4 and the positioning mechanism 5 through an external control system. The external control system is existing technology and will not be described in detail.

[0040] Reference Figure 2 A welding execution arm 41 is rotatably connected to the welding robot 4, and a welding torch 42 is rotatably connected to the welding execution arm 41; the welding torch 42 is used to weld the workpiece 6 on the displacement mechanism 5.

[0041] Reference Figure 1 , Figure 3 and Figure 4 The positioning mechanism 5 includes a positioning frame 51, a positioning motor 52, a clamping plate 53, a protective baffle 56, and a deflection motor 57. The positioning motor 52 is fixedly connected to the base 1, and the output shaft of the positioning motor 52 is vertically arranged. The lower end of the positioning frame 51 is fixedly connected to the output shaft of the positioning motor 52. The positioning frame 51 is rotatably connected to the base 1 through the positioning motor 52. The positioning frame 51 is in the shape of an "I". The two clamping plates 53 are rotatably connected to the two open ends of the positioning frame 51. The deflection motor 57 is fixedly connected to the positioning frame 51. In this embodiment, a deflection motor 57 is arranged on each side of each clamping plate 53. The deflection motor 57 is used to drive the clamping plate 53 to deflect. The protective baffle 56 is bolted to the positioning frame 51 between the two clamping plates 53.

[0042] Reference Figure 1 , Figure 3The clamping plate 53 is used to mount the workpiece 6. The purpose of having two clamping plates 53 is that when one clamping plate 53 is below the welding robot 4, the other clamping plate 53 is opposite the welding robot 4. This allows the welding robot 4 to weld the workpiece 6 on the lower clamping plate 53 using the welding torch 42, while the operator can mount the workpiece 6 on the other clamping plate 53. After the workpiece 6 on the lower clamping plate 53 of the welding robot 4 is welded, the positioner motor 52 drives the positioner frame 51 to rotate 180°, exchanging the positions of the two clamping plates 53, thus enabling continuous robot operation and improving work efficiency. To facilitate welding of the workpiece 6 by the welding robot 4, the clamping plate 53 is in a vertical position during welding; to facilitate mounting the workpiece 6 on the clamping plate 53 by the operator, the clamping plate 53 is in a horizontal position when mounting the workpiece 6. To reduce the amount of sparks generated by the welding robot 4 during welding and to avoid safety hazards to the operator mounting the workpiece on the other clamping plate 53, a protective baffle 56 is installed in the middle of the positioner frame 51.

[0043] Reference Figures 5-7 In this embodiment, the clamping plate 53 in a horizontal state is used for description. The displacement mechanism 5 also includes a pushing component 54 and a clamping component 55. The pushing component 54 is used to push the workpiece 6 placed on the clamping plate 53 toward the clamping component 55, and the clamping component 55 clamps the workpiece 6 on the clamping plate 53. Specifically, the pushing assembly 54 includes a pushing motor 541, a connecting shaft 543, and a screw 548. The pushing motor 541 is fixedly connected to the clamping plate 53, and a drive gear 542 is fixedly connected to the output shaft of the pushing motor 541. Two connecting shafts 543 are provided, respectively located on both sides of the pushing motor 541. The axes of the two connecting shafts 543 are perpendicular to the axis of the output shaft of the pushing motor 541. Each connecting shaft 543 is rotatably connected to the clamping plate 53 via a mounting base 544. A first driven gear 545 is fixedly connected to the end of each connecting shaft 543 closest to the pushing motor 541, and a second driven gear 546 is fixedly connected to the end of each connecting shaft 543 furthest from the pushing motor 541. The drive motor 541 engages with two first driven gears 545 near the drive motor 541 via the drive gear 542, causing the two connecting shafts 543 to rotate on the clamping plate 53. Two screws 548 are provided, and a third driven gear 547 is fixedly connected to each screw 548. Each screw 548 is rotatably connected to the clamping plate 53 via a support base 549. The two screws 548 are respectively located on one side of the two connecting shafts 543, and the axes of the two connecting shafts 543 are perpendicular to the axis of any screw 548. The second driven gears 546 on the two connecting shafts 543 respectively engage with the third driven gears 547 on the two screws 548. In this embodiment, the helical directions of the two screws 548 are opposite.

[0044] Reference Figures 5-7 The pushing assembly 54 also includes a pushing plate 5410. The clamping plate 53 has two movable support grooves 531 for the pushing plate 5410 to slide. In this embodiment, the pushing plate 5410 is an "L"-shaped plate, wherein two support blocks 5411 are provided on the bottom wall of the horizontal plate. The pushing plate 5410 is slidably connected to the movable support grooves 531 through the support blocks 5411. Each support block 5411 is also provided with a threaded hole. The two support blocks 5411 are respectively connected to two screws 548 through their own threaded holes. When the two screws 548 rotate, the two screws 548 respectively drive the pushing plate 5410 to move on the clamping plate 53 through the two support blocks 5411. The vertical plate on the pushing plate 5410 is used to push the workpiece 6.

[0045] Reference Figures 5-7 A positioning block 532 is also fixedly connected to the clamping plate 53. In this embodiment, the positioning block 532 is configured as a V-shaped block. The workpiece 6 includes a pin 61 and a connecting plate 62. (Refer to...) Figure 1 The welding robot 4 welds the connecting plate 62 onto the pin 61. Positioning blocks 532 are used to hold the pins 61. In this embodiment, five columns of positioning blocks 532 are arranged, with two positioning blocks 532 in each column. Each column of positioning blocks 532 holds one pin 61. The pins 61 are pushed towards the clamping assembly 55 by the pushing plate 5410. The pushing plate 5410 aligns the ends of the five pins 61 to facilitate welding of the workpiece 6 by the welding robot 4. The positioning blocks 532 on the clamping plate are configured as V-shaped blocks, and the clamping end of the clamping assembly 55 is also configured as a V-shaped block to facilitate clamping workpieces 6 of different diameters.

[0046] Reference Figure 5 , Figure 8 The clamping assembly 55 includes a first support column 551, a second support column 552, a clamping beam 553, a positioning element 556, and a clamping element 557. In this embodiment, the first support column 551 and the second support column 552 are vertically fixedly connected to the two ends of the long axis of the clamping plate 53, respectively. One end of the clamping beam 553 is rotatably connected to the first support column 551. A connecting block 5521 is fixedly connected to the second support column 552. The connecting block 5521 is used to support the clamping beam 553. An avoidance groove 555 is provided at one end of the clamping beam 553 near the second support column 552. The clamping beam 553 passes through the avoidance groove 555 through the upper end of the second support column 552 and is supported by the connecting block 5521.

[0047] Reference Figure 9The positioning component 556 includes a positioning support block 5561, a positioning rod 5562, and a positioning spring 5564. The positioning support block 5561 is fixedly connected to the end of the clamping beam 553 near the second support column 552. The positioning rod 5562 is slidably connected to the positioning support block 5561. The end of the positioning rod 5562 passes through the end face of the clamping beam 553 into the clearance groove 555, and the end of the positioning rod 5562 also passes through the positioning hole 5522 opened on the second support column 552, thereby positioning the clamping beam 553 on the second support column 552. A connecting piece 5563 is fixedly connected to the positioning rod 5562, and the connecting piece 5563 is located inside the positioning support block 5561. The positioning spring 5564 is sleeved on the positioning rod 5562, and the positioning spring 5564 is located inside the positioning support block 5561. One end of the positioning spring 5564 abuts against the positioning support block 5561, and the other end of the positioning spring 5564 abuts against the connecting piece 5563, thereby keeping the positioning rod 5562 inserted into the second support column 552.

[0048] Reference Figure 5 , Figure 8 The clamping component 557 includes a clamping rod 5571, clamping blocks 5572, and clamping screws 5573. The clamping beam 553 has two sliding support grooves 554 for sliding connection of the clamping rod 5571. A vertical rod is provided at each end of the long axis of the clamping rod 5571, and the clamping rod 5571 is slidably connected to the clamping beam 553 via the vertical rods. Five clamping blocks 5572 are fixedly connected to the lower end of the clamping rod 5571, and the lower end of the clamping screw 5573... The clamping rod 5571 is rotatably connected to the clamping beam 553, which also has threaded holes for connecting the clamping screw 5573. When the clamping screw 5573 is rotated in the forward direction, the clamping rod 5571 moves downward and the clamping rod 5571 positions the five pins 61 on the five positioning blocks 532 one by one through the five clamping blocks 5572. When the clamping screw 5573 is rotated in the reverse direction, the clamping rod 5571 moves upward, thereby releasing the positioning of the pins 61.

[0049] The implementation principle of the frame pin welding auxiliary device in this application embodiment is as follows: The worker first ascends to the control platform 21 via the connecting ladder 23, and inputs the operating instructions for the welding robot 4 and the positioning mechanism 5 on the control panel 22 mounted on the column 2. Then, the welding robot 4 and the positioning mechanism 5 are started. The worker installs five pins 61 on the clamping plate 53 opposite the welding robot 4. Subsequently, the drive motor 541, through the connecting shaft 543 and the screw 548, drives the push plate 5410 to push the pins 61 towards the clamping assembly 55. Then, the worker uses the clamping assembly 55 to fix the pins 61. The workpiece 6 is fixed on the clamping plate 53. Then, the deflection motor 57 rotates the clamping plate 53 from a horizontal position to a vertical position. Then, the operator places the connecting plate 62 on the upper end of the pin 61 so that the welding robot 4 can weld the connecting plate 62 onto the pin 61. Then, the positioner motor 52 drives the positioner frame 51 to rotate, rotating the clamping plate 53 with the workpiece 6 to below the welding gun 42 of the welding robot 4. Then the welding robot 4 works. While the welding robot 4 is welding the workpiece 6 below the welding gun 42, the operator can install the workpiece 6 on the clamping plate 53 opposite the welding robot 4.

[0050] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
