[0001] This utility model relates to the field of welding positioning technology, specifically to a welding positioning device for an automotive air suspension balance beam. Background Technology

[0002] As an important load-bearing structural component of air suspension, the balance beam is widely used in single-axle air suspension vehicles. The balance beam also integrates the installation functions of the axle, airbag, stabilizer bar, thrust bar, and shock absorber. The main body of the balance beam is usually cast in the shape of a rectangular tube, and during welding, reinforcing ribs and connecting plate structures need to be welded to the rectangular tube.

[0003] The existing technology has the following problems: Traditional welding positioning devices have a fixed positioning spacing when positioning the equalization beam. However, the equalization beams for cars and trucks are of different sizes, and the device cannot adjust the positioning spacing according to the size of the equalization beam. In addition, the equalization beam needs to be welded with reinforcing ribs on all four sides, and the positioning device cannot turn the equalization beam according to the welding surface, so the welding efficiency of the equalization beam cannot be guaranteed. Utility Model Content

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figure 1-4 In this embodiment: a welding and positioning device for automotive air suspension balance beams includes a workbench 1, a control panel 2 connected to one side of the workbench 1, and a positioning component 3 fixedly connected to the inner wall of the workbench 1. The positioning component 3 includes a connecting seat 31 fixedly connected to the inner wall of the workbench 1. A first motor 32 is fixedly connected inside the connecting seat 31, ensuring that the second motor 37 drives the first threaded rod 38 to rotate and move the movable block 39. When the movable block 39 moves and moves the positioning seat 311 to the appropriate position, the third motor 312 drives the second threaded rod 313 to rotate. The rotation of the second threaded rod 313 drives the abutment block 314 to move and clamp and position the equalizing beam. At the same time, the first motor 32 drives the drive gear 33 and the transmission gear 34 to rotate. The rotation of the transmission gear 34 drives the connecting column 35 and the fixed seat 36 to rotate. The rotation of the fixed seat 36 turns the welding surface of the equalizing beam. The first motor 32, the second motor 37, and the third motor 312 all use a programmable logic controller (Siemens S7-200SMART series PLC) as the core control unit. Through programming, precise start-stop and speed control of the motors can be achieved. Its internal program can convert push-button switch signals (such as start, stop, and speed control commands) into pulse outputs to drive the motors to run. The first motor 32, the second motor 37, and the third motor 312 are all connected to the circuit of the control panel 2.

[0017] In this embodiment, the positioning component 3 further includes a drive gear 33. The output end of the first motor 32 is fixedly connected to the drive gear 33. The surface of the drive gear 33 is meshed with a transmission gear 34. One end of the transmission gear 34 is fixedly connected to a connecting post 35. One end of the connecting post 35 is fixedly connected to a fixed seat 36. One side of the fixed seat 36 is fixedly connected to a second motor 37. The output end of the second motor 37 is fixedly connected to a first threaded rod 38. The surface of the first threaded rod 38 is threadedly connected to a movable block 39. The interior of the movable block 39 is slidably connected to a guide rod 310. One end of the movable block 39 is fixedly connected to a positioning seat 311. One side of the positioning seat 311 is fixedly connected to a third motor 312. The output end of the machine 312 is fixedly connected to a second threaded rod 313, and the surface of the second threaded rod 313 is threadedly connected to an abutment block 314. By setting the positioning component 3, it is ensured that when the second motor 37 drives the first threaded rod 38 to rotate and move the movable block 39, and the movable block 39 moves and moves the positioning seat 311 to a suitable position, the third motor 312 drives the second threaded rod 313 to rotate. The rotation of the second threaded rod 313 drives the abutment block 314 to move and clamp and position the equalization beam. At the same time, the first motor 32 drives the drive gear 33 and the transmission gear 34 to rotate. The rotation of the transmission gear 34 causes the connecting column 35 and the fixed seat 36 to rotate. The rotation of the fixed seat 36 causes the welding surface of the equalization beam to turn.

[0018] The workbench 1 has a rotating groove inside that matches the size of the connecting column 35. The connecting column 35 is rotatably connected to the inside of the workbench 1 through the rotating groove, which ensures that the rotation position of the connecting column 35 is limited by the rotating groove, and that the position of the connecting column 35 will not deviate when it rotates.

[0019] The transmission gear 34, the connecting column 35, and the fixed seat 36 are all on the same vertical line. The diameter of the fixed seat 36 is larger than the diameter of the transmission gear 34, and the diameter of the transmission gear 34 is larger than the diameter of the connecting column 35. This ensures that when the transmission gear 34 rotates, it can synchronously drive the connecting column 35 and the fixed seat 36 to rotate. The rotation of the fixed seat 36 can change the direction of the equalization beam welding surface on the surface of the positioning seat 311.

[0020] The threads on the surface of the first threaded rod 38 are divided into two groups, which are symmetrically distributed on the surface of the first threaded rod 38. Each group of threads is provided with a set of movable blocks 39, which ensures that when the first threaded rod 38 rotates, it can drive the two sets of movable blocks 39 to move symmetrically. The movement of the movable blocks 39 drives the positioning seat 311 to move. The movement of the positioning seat 311 can be adapted to the positioning of the equalization beam of different sizes.

[0021] The threads on the surface of the second threaded rod 313 are divided into two groups, which are symmetrically distributed on the surface of the second threaded rod 313. Each group of threads is provided with a set of abutment blocks 314, which ensures that when the second threaded rod 313 rotates, it can drive the two sets of abutment blocks 314 to move symmetrically. The movement of the abutment blocks 314 abuts and positions the equalization beam placed on the surface of the positioning seat 311.

[0022] The surface of the positioning seat 311 is provided with a movable groove that matches the size of the abutment block 314. The abutment block 314 is slidably connected to the surface of the positioning seat 311 through the movable groove, which ensures that the movement trajectory of the abutment block 314 matches the position of the movable groove and that the position of the abutment block 314 will not shift.

[0023] The working principle and usage process of this utility model are as follows: This utility model is a welding and positioning device for an automotive air suspension balance beam. When the balance beam needs to be clamped, positioned, and welded, the second motor 37 drives the first threaded rod 38 to rotate. The rotation of the first threaded rod 38 causes two sets of movable blocks 39 to move symmetrically. The movement of the movable blocks 39 adjusts the positioning distance between the two sets of positioning seats 311. When the distance between the positioning seats 311 is adjusted to a suitable position, the third motor 312 drives the second threaded rod 313 to rotate. The second threaded rod 313 drives two sets of abutment blocks 314 to weld and position the balance beam. Simultaneously, the first motor 32 drives the drive gear 33 to rotate. The drive gear 33 rotates the transmission gear 34, which in turn rotates the connecting column 35 and the fixed seat 36. The rotation of the fixed seat 36 rotates the balance beam welding surface on the positioning seat 311, ensuring that the device can adapt to balance beams of different sizes for positioning and to achieve the desired rotation of the balance beam welding surface.

[0024] The aforementioned device is used by workers in this field by connecting the motor to an external power source.

[0025] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
