Description

Technical Field

[0001] This invention relates to the field of automotive dashboard crossbeam processing technology, and particularly to an automotive dashboard crossbeam processing apparatus. Background Technology

[0002] The dashboard crossbeam is an important component of the car's internal structure. It not only provides installation and support for the dashboard assembly and other system components (such as the steering column, air conditioning, entertainment system, instrument cluster, front passenger side airbag, etc.), but is also directly connected to the vehicle body. In a vehicle collision, it plays a crucial role in energy absorption and load transfer, directly affecting the safety protection performance of the occupants. Currently, in automobiles, dashboard crossbeams are usually made by clamping various tubing components and then welding them together.

[0003] The applicant discovered through a search that a Chinese patent, "A Welding Apparatus for Processing Crossbeams of Automotive Central Control Instrument Panels," with publication number "CN218081055U," discloses a method where the crossbeam is placed in a slot, a rectangular block is slidably connected within the slot, and a U-shaped connecting block slides on a moving frame. The movement of the U-shaped connecting block moves the welding torch, facilitating welding of the crossbeam. After welding one side of the crossbeam, the sliding block, connected within a groove, pushes the moving frame, causing it to move to the other side of the crossbeam for welding. While this patent allows welding on both sides of the component, the welding position is not limited to the two sides when the component is clamped. Depending on the crossbeam's position, the welding locations on the sides may vary. Disassembling and re-fixing the component to find the welding location would be cumbersome, delaying assembly and reducing work efficiency. Summary of the Invention

[0022] 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.

[0023] This invention provides, for example Figure 1-7The diagram shows a machining device for an automotive dashboard crossbeam, comprising a welding table 1. A guide rail 2 is fixedly connected to the top surface of the welding table 1. Two limiting plates 3 are slidably connected along the top surface of the guide rail 2. Each limiting plate 3 has a through hole 31 inside, and an annular groove 311 inside the through hole 31. A self-locking rotating plate 32 is rotatably connected inside the annular groove 311. Four annularly arranged extrusion pieces 33 for clamping one end of the dashboard crossbeam are provided on the opposite side of the two rotating plates 32. Three equally spaced longitudinal fixing devices 4 are fixedly connected to the top surface of the welding table 1. Each longitudinal fixing device 4 includes a support plate 41. A through groove is provided at the upper end of the support plate 41, and a rotatable outer ring 48 is provided in the groove at the bottom of the inner wall of the through groove. Three equally spaced inclined blocks 482 are fixedly connected to the inner wall of the outer ring 48. An inner ring 42 is fixedly connected to the top of the support plate 41, and three top plates are fixedly connected to the inner wall of the inner ring 42. 43. Push rods 44 are slidably connected inside the three top plates 43. A fan-shaped fixing block 46 is fixedly connected to the top of the push rod 44. A roller 47 is rotatably connected inside the fan-shaped fixing block 46. A spring 3 45 is fixedly connected between the top plate 43 and the fan-shaped fixing block 46. The bottom end of the push rod 44 abuts against the inclined block 482. A movable welding torch 54 is provided on one side of the top surface of the longitudinal fixing device 4. By setting the longitudinal fixing device 4, the longitudinal direction of the welded part can be fixed, but it is not limited to the welded part being able to rotate. By setting the limiting plate 3, the limiting plate 3 can fix the transverse direction of the welded part. At the same time, the end point of the welded part can be fixed by the extrusion part 33 on the surface of the rotating plate 32. At this time, the rotation of the rotating plate 32 drives the extrusion part 33 to rotate, and then the extrusion part 33 drives the crossbeam to rotate, so that the welding torch 54 can weld different welding points of the crossbeam.

[0024] like Figure 1 As shown, the top surface of the welding table 1 is provided with multiple filter holes 6, and the inside of the welding table 1 is provided with a pull-out box 7 for collecting welding materials. Both ends of the guide rail 2 are fixedly connected with blocks 21 to prevent the limiting plates 3 from slipping. The inside of the guide rail 2 is provided with multiple equally spaced insertion holes 22. One side of the two limiting plates 3 is fixedly connected with a C-shaped fixing plate 37, and the inside of the C-shaped fixing plate 37 is inserted with a pin 371 that matches the insertion hole 22.

[0025] like Figure 2As shown, a set of vertical plates 5 are fixedly connected to the top surface of the welding table 1. A guide plate 51 is fixedly connected between the two vertical plates 5. A guide groove 511 is opened on one side of the guide plate 51. A C-shaped slide plate 53 is slidably connected inside the guide groove 511. A threaded rod 52 is rotatably connected between the two vertical plates 5. A slider 531 is threadedly connected to the outer wall of the threaded rod 52. The top surface of the slider 531 is fixedly connected to the inner wall of the C-shaped slide plate 53. The top surface of the C-shaped slide plate 53 is fixedly connected to the bottom surface of the welding gun 54 through a hinge. A servo motor 55 is fixedly connected to one side of the vertical plate 5. The output end of the servo motor 55 is fixedly connected to one end of the threaded rod 52. The servo motor 55 drives the threaded rod 52 to rotate. The threaded rod 52 drives the slider 531 to move on the threaded rod 52, which in turn drives the C-shaped slide plate 53 to move on the guide plate 51, which in turn drives the welding gun 54 to move, thereby welding different welding points of the crossbeam.

[0026] like Figure 4 As shown, the extrusion component 33 includes a fixed plate 331, which is fixedly connected to the rotating plate 32. A telescopic rod 332 is fixedly connected to one side of the fixed plate 331, and a trapezoidal clamping block 334 is fixedly connected to the top of the telescopic rod 332. The trapezoidal clamping block 334 is a trapezoidal block, and the inclined surface of the trapezoidal block faces the direction of the longitudinal fixing device 4. A spring 333 is fixedly connected between the fixed plate 331 and the trapezoidal clamping block 334.

[0027] like Figure 4 and Figure 5 As shown, one side of the rotating plate 32 is provided with a retractable L-shaped insert rod 363, and the side wall of the annular groove 311 is provided with a plurality of equally spaced insertion holes 312 that are adapted to the L-shaped insert rod 363. The rotating plate 32 can rotate and self-lock by the L-shaped insert rod 363 cooperating with the insertion holes 312.

[0028] like Figure 6 As shown, the outer wall of the outer ring 48 is fixedly connected with teeth 481, and the inside of the support plate 41 is rotatably connected with a rotating rod 49. One end of the rotating rod 49 is fixedly connected with a worm gear 491, and the worm gear 491 meshes with the teeth 481.

[0029] like Figure 7As shown, hollow rotating rods 34 are fixedly connected to opposite sides of the two rotating plates 32. A handle 35 is fixedly connected to the top of each hollow rotating rod 34. A pressing rod 341 is slidably connected inside the hollow rotating rod 34. The bottom end of the pressing rod 341 is inclined. An inner groove 36 is formed inside the rotating plate 32. Two parallel limiting grooves 361 are formed on the inner wall of the inner groove 36. A trapezoidal pressing rod 362 is slidably connected to the two limiting grooves 361. A spring 36 is fixedly connected to the outer wall of the L-shaped insert rod 363. 4. The top of the L-shaped insert 363 is an inclined surface, and the trapezoidal pressing rod 362 is an isosceles trapezoid. The two inclined surfaces of the trapezoidal pressing rod 362 are pressed against the pressing rod 341 and the inclined surface of the L-shaped insert 363, respectively. By pressing down the pressing rod 341, the trapezoidal pressing rod 362 can be pressed, causing the trapezoidal pressing rod 362 to press towards the L-shaped insert 363, causing the L-shaped insert 363 to move upward, thereby causing the bottom end of the L-shaped insert 363 to disengage from the second insertion hole 312, thus achieving self-locking opening.

[0030] Working principle of this invention: In use, the welded part is first inserted into the inner ring 42 to fix it longitudinally. During fixation, the rotating rod 49 is rotated first, which drives the worm gear 491 to rotate. The rotation of the worm gear 491 drives the teeth 481 to rotate, which in turn drives the outer ring 48 to rotate. The outer ring 48 drives the inclined block 482 to rotate. The rotation of the inclined block 482 causes the inclined block 482 to press against the push rod 44, which in turn causes the push rod 44 to drive the fan-shaped fixing block 46 to press towards the center of the inner ring 42, thereby fixing the welded part inserted inside the inner ring 42. The roller 47 prevents the longitudinally fixed rotating part from rotating. After longitudinal fixation, the longitudinal position of the welded part is fixed. First, the pin 371 is pulled to pull the pin 371 out of the insertion hole 22. Then, the limiting plate 3 is pushed to press against the tail end of the welded part, causing the tail of the welded part to... The weldment is pressed into four extrusion pieces 33 on the surface of the rotating plate 32. The rotating plate 32 fixes the weldment laterally, and the four extrusion pieces 33 fix the tail end of the weldment to facilitate rotation. During rotation, the self-locking mechanism of the rotating plate 32 needs to be opened first. Press the pressing rod 341 to press the trapezoidal extrusion rod 362, causing it to move towards the L-shaped insertion rod 363. Due to the action of the inclined surfaces of the trapezoidal extrusion rod 362 and the L-shaped insertion rod 363, the L-shaped insertion rod 363 retracts, causing its bottom end to disengage from the insertion hole 312, thus locking and opening. Then, rotate the handle 35 to drive the hollow rotating rod 34 to rotate, which in turn drives the rotating plate 32 to rotate. The rotating plate 32 causes the weldment to flip, allowing welding to be performed on different positions of the weldment without disassembling and replacing it.

[0031] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention 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. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
