[0002] Currently, there are many specifications for radiators used in engineering vehicles and commercial vehicles, but they are generally consistent in shape, differing only in size. However, in the current radiator manufacturing process, different tooling needs to be designed for different radiator sizes for clamping and welding. Because the tooling dimensions vary, it is difficult to achieve automated welding, thus increasing production costs. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a welding fixture for radiators of engineering vehicles and commercial vehicles, which can quickly position and clamp radiators with the same structure and within a certain size range, thereby realizing automatic welding after clamping.

[0004] The technical solution adopted by this utility model is as follows: a welding fixture for radiators of engineering vehicles and commercial vehicles, including a base, an L-shaped support platform mounted on the base, a worktable mounted on the horizontal surface of the support platform, lifting cylinders mounted on both sides of the vertical surface of the support platform, a lifting seat mounted between the telescopic ends of the two lifting cylinders, a number of evenly distributed adjustment holes opened along its length on the lifting seat, a number of end-face positioning rods with gradually changing lengths provided on the lifting seat, an adjustment seat formed at one end of each end-face positioning rod, and a locking hole and locking screw matching the adjustment hole provided on the adjustment seat, an end-face positioning stop wheel mounted on the other end of the end-face positioning rod, guide rails symmetrically mounted on both sides of the worktable along its length, a fixed seat mounted on the centerline of the worktable along its length, and evenly distributed holes opened on the fixed seat. The guide rail has several fixing holes, and a sliding seat that slides with it is installed on the guide rail. Several connecting holes are evenly opened on both ends of the sliding seat. A positioning hole matching the fixing holes is opened in the middle of the sliding seat, and a corresponding positioning locking screw is provided at the positioning hole. Clamping seats are installed at both ends of the sliding seat. A support block is fixedly installed on the bottom front side of each clamping seat. Side positioning blocks are fixedly installed on the middle front side of two clamping seats on the same sliding seat. Connecting seats are provided on the front side of two clamping seats on another sliding seat, corresponding to the side positioning blocks. One side of the connecting seat extends out of the clamping seat, and a side pressing cylinder is fixedly installed on the rear side of the extended part. The telescopic end of the side pressing cylinder passes through the connecting seat and is fixedly connected to the side pressing block. A top pressing mechanism is fixedly installed on the rear side of the clamping seat. The top pressing block of the top pressing mechanism corresponds to the support block.

[0005] Preferably, the bottom of each end of the sliding seat is formed with a slider, and the two sliders are respectively mounted on two guide rails and slide in cooperation with the guide rails.

[0006] Preferably, the two sides of the middle part of the sliding seat corresponding to the fixed seat extend outward to form a positioning seat, and the two ends of the positioning seat are respectively provided with positioning holes that match the fixing holes.

[0007] Preferably, the center distance between the two positioning holes is the same as the center distance between the two fixing holes located at both ends of the three consecutive fixing holes.

[0019] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0020] Example

[0021] like Figure 1 , Figure 2 and Figure 3 As shown, the radiator welding fixture for engineering vehicles and commercial vehicles provided in this embodiment includes a base 1, an L-shaped support platform 2 installed on the base, a worktable 3 installed on the horizontal surface of the support platform 2, and lifting cylinders 4 installed on both sides of the vertical surface of the support platform 2. The two lifting cylinders 4 are symmetrically fixedly installed on the top two sides of the vertical surface of the support platform 2, with the extension and retraction ends of the two lifting cylinders 4 pointing vertically downwards. A lifting seat 5 is fixedly installed between the extension and retraction ends of the two lifting cylinders 4. The operation of the lifting cylinders 4 drives the lifting seat 5 to rise and fall vertically along the vertical surface of the support platform 2.

[0022] The lifting seat 5 has several evenly distributed adjustment holes 6 along its length direction, and the lifting seat 5 is provided with several end face positioning rods 7 with gradually changing lengths. One end of each end face positioning rod 7 is formed with an adjustment seat 8, and the adjustment seat 8 is provided with a locking hole 9 and a locking screw 10 that match the adjustment holes 6. The end face positioning rods 7 are installed through the adjustment seat 8 and the adjustment holes 6, and the spacing between the end face positioning rods 7 is adjusted and controlled according to the actual processed product, thereby controlling the oblique angle of the line connecting the ends of the end face positioning rods 7. An end face positioning stop wheel 11 is installed at the end of the end face positioning rod 7 away from the adjustment seat 8, so that the end face of the line connecting multiple end face positioning stop wheels 11 with different oblique angles is obtained.

[0023] The workbench 3 is symmetrically equipped with guide rails 12 on both sides along its length direction. A fixed seat 13 is installed on the center line along its length direction. Several fixed holes 14 are evenly opened on the fixed seat 13. A sliding seat 15 is installed on the guide rail 12 and slides with it. Sliding blocks are formed at the bottom of both ends of the sliding seat 15. The two sliding blocks slide with the two guide rails 12 respectively. The two sides of the middle of the sliding seat 15 corresponding to the fixed seat 13 extend outward to form a positioning seat 26. The two ends of the positioning seat 26 are respectively opened with positioning holes 17 that match the fixed holes 14. A corresponding positioning screw 18 is provided at the positioning hole 17. In order to ensure installation accuracy, the center distance between the two positioning holes 17 is the same as the center distance between the two fixed holes 14 at the two ends of the three consecutive fixed holes 14.

[0024] Several evenly distributed connecting holes 16 are symmetrically opened on the sliding seats 15 on both sides of the positioning seat 26. The sliding seats 15 are respectively provided with clamping seats 19 at both ends. The bottom of the clamping seat 19 is provided with mounting holes 27 that correspond to and match the connecting holes 16, and mounting screws 28 that match the mounting holes 27 are provided at the mounting holes 27. The mounting holes 27 and the connecting holes 16 are fixedly connected by the mounting screws 28, thereby fixing the clamping seat 19 on the sliding seat 15. In this embodiment, the two clamping seats 19 on the same sliding seat 15 are symmetrically installed.

[0025] Each clamping seat 19 has a support block 20 fixedly installed at the bottom front side. Two clamping seats 19 on the same sliding seat 15 have side positioning blocks 21 fixedly installed at the middle front side. Two clamping seats 19 on another sliding seat 15 have connecting seats 22 at positions corresponding to the side positioning blocks 21 on their front sides. One side of the connecting seat 22 extends out of the clamping seat 19, and a side pressing cylinder 23 is fixedly installed on the rear side of the extended portion. The telescopic end of the side pressing cylinder 23 passes through the connecting seat 22 and is fixedly connected to a side pressing block 24. A top surface pressing mechanism 25 is fixedly installed on the rear side of each clamping seat 19. The top surface pressing mechanism 25 includes a mounting base 2501 and a top surface... The mounting base 2501 is fixedly installed on the rear side of the clamping base 19. The top surface pressing cylinder 2502 is fixedly installed at the bottom of the mounting base 2501. The mounting base 2501 is equipped with a hinge 2505 that drives the pressing connector 2503 to rotate. The telescopic end of the top surface pressing cylinder 2502 extends into the mounting base 2501 and is connected to the hinge 2505 through a transmission connector. The end of the pressing connector 2503 away from the mounting base 2501 is connected to the top surface pressing block 2504. The top surface pressing block 2504 corresponds to the support platform 2.

[0026] In this embodiment, the adjusting hole 6, locking hole 9, locking screw 10, fixing hole 14, positioning hole 17, positioning screw 18, connecting hole 16, mounting hole 27, and mounting screw 28 are all threaded connections.

[0027] In use, the sliding seat 15 is controlled to slide according to the actual size of the product to be processed, thereby controlling the distance between the two sliding seats 15. That is, the clamping distance of the clamping seat 19Y axis is controlled according to the width of the actual product to be processed. Then, the distance between the end face positioning rods 7 is adjusted to match the inclined end face of the actual product to be processed. Then, the height of the lifting seat 5 is controlled by the lifting cylinder 4 so that the height of the positioning wheel 11 corresponds to the height of the product to be processed.

[0028] By controlling the top surface clamping cylinder 2502 to operate, the top surface clamping component is flipped upward. At the same time, the side clamping cylinder 23 is controlled to operate, retracting the side clamping block 24. The product to be processed is placed on the surface of the support block 20 of the four clamping seats 19, and one side of the product to be processed is pressed against the surface of the side positioning block 21 to achieve positioning in the Y-axis direction. Then, the product to be processed is moved towards the positioning wheel 11 so that the inclined end face of the product to be processed is pressed against each positioning wheel 11 to achieve positioning in the X-axis direction. Finally, the top surface clamping cylinder 2502 is controlled to press down the top surface clamping block 2504, and the side clamping cylinder 23 is controlled to extend and press the side clamping block 24, thereby completing the clamping of the product to be processed.

[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any modifications and substitutions based on the technical solutions and utility model concepts provided by the present utility model should be covered within the protection scope of the present utility model.
