Description
Technical Field
[0001] This utility model relates to the field of parallelism adjustment technology, specifically to a parallelism adjustment device for a large sheet metal housing. Background Technology
[0002] Large sheet metal housings typically refer to large metal shells manufactured using sheet metal processing technology. They are commonly used in various industrial equipment, electronic equipment, machinery housings, cabinets, and other fields. These housings not only need to have strength and stability, but also usually require a certain degree of precision. In particular, the control of parallelism, perpendicularity, and dimensional accuracy is crucial during the assembly process. Parallelism is of paramount importance in the manufacturing and assembly of sheet metal housings, especially when manufacturing large sheet metal housings. Due to the increase in size and weight, the bending and deformation of the sheet metal may affect the final assembly accuracy.
[0003] Conventional parallelism adjustment devices adjust parallelism by grinding or applying pressure. However, some shell surfaces are tilted at a certain angle, making it difficult for clamps to effectively fix the shell. During parallelism adjustment, the shell is also prone to displacement due to force, causing the adjustment position to shift and increasing the parallelism deviation of the shell. The adjustment efficiency is low. In general adjustment devices, the position of the adjustment head is not easy to adjust, and the device is difficult to effectively adjust the parallelism at any position on the shell surface. To address the above problems, a parallelism adjustment device for large sheet metal shells is proposed. Utility Model Content
[0004] To solve the above-mentioned technical problems, a parallelism adjustment device for large sheet metal housings is provided. This device addresses the issues of conventional parallelism adjustment devices that rely on grinding or applying pressure to adjust parallelism, where some housing surfaces are tilted at an angle, making it difficult for clamps to effectively fix the housing. Furthermore, the housing is prone to displacement under stress during parallelism adjustment, leading to positional shifts and increased parallelism deviation. Additionally, conventional adjustment devices often suffer from difficulty in adjusting the position of the adjustment head, making it challenging to effectively adjust parallelism at any point on the housing surface.

A lifting push rod 3 is fixedly installed at the center of the lower side of the processing platform 1. The output end of the lifting push rod 3 passes through the lower side of the processing platform 1 and is fixedly connected to a shelf 4, which effectively changes the height difference between the adjustment head 16 and the shell, and controls the degree of parallelism adjustment.
[0019] Specifically, fixing components 5 are provided at both the left and right ends of the upper side of the shelf 4. Each fixing component 5 includes a fixing plate 501. The lower side of the fixing plate 501 is fixedly connected to the upper side of the shelf 4. A first adjusting threaded rod 502 is threadedly connected to the outer side of the fixing plate 501. A first knob 503 is fixedly connected to the outer end of the first adjusting threaded rod 502. The end of the first adjusting threaded rod 502 passes through the outer side of the fixing plate 501 and is rotatably connected to a transverse clamping plate 504. A first friction pad 505 is fixedly connected to the inner side of the transverse clamping plate 504. A connecting plate 506 is fixedly connected to the upper side of the transverse clamping plate 504. The upper side of the connecting plate 506 is threaded with a second adjusting threaded rod 507. The upper end of the second adjusting threaded rod 507 is fixedly connected with a second knob 508. The lower side of the second adjusting threaded rod 507 passes through the upper side of the connecting plate 506 and is rotatably connected with a connecting block 509. The front and rear sides of the connecting block 509 are rotatably connected with rotating plates 510 through connecting rods. The lower side of the two sets of rotating plates 510 is fixedly connected with a vertical clamping plate 511. The lower side of the vertical clamping plate 511 is fixedly connected with a second friction pad 512, which effectively limits and fixes the shell in all directions, preventing displacement under force during the shell adjustment process.
[0020] Specifically, the upper front and rear ends of the processing platform 1 are fixedly connected to mounting supports 6. A sliding groove 7 is provided through the upper side of the mounting support 6, and an I-shaped slider 8 is slidably connected inside the sliding groove 7. An adjusting motor 9 is fixedly installed at the upper front end of the mounting support 6. The output end of the adjusting motor 9 passes through the front side of the mounting support 6 and is fixedly connected to a rotating threaded rod 10, effectively adjusting the position of the adjusting head 16 in the front-rear direction. A rotating support 11 is fixedly installed inside the rear side of the sliding groove 7. The end of the rotating threaded rod 10 passes through the front side of the I-shaped slider 8 and is rotatably connected inside the rotating support 11. A mounting bracket 12 is fixedly connected to the lower side of the I-shaped slider 8 via a connecting rod. The mounting bracket 12 has front and rear... Both ends are fixedly connected with slide rods 13, and the surfaces of the two slide rods 13 are slidably connected with connecting slide plates 14. The inner sides of the two connecting slide plates 14 are fixedly connected with adjustment boxes 15. The lower end of the adjustment box 15 is snapped with an adjustment head 16. A grinding motor is installed inside the adjustment box 15. The adjustment head 16 can be equipped with a grinding head or a pressure head as needed. An adjustment push rod 17 is fixedly installed on the left side of the mounting frame 12. The output end of the adjustment push rod 17 passes through the left side plate of the mounting frame 12 and is fixedly connected to the left side of the adjustment box 15, effectively adjusting the position of the adjustment head 16 in the left and right directions. Positioning pins 18 are provided at the four corners of the upper side of the shelf 4, and the position of the shell on the shelf 4 can be determined by laser scanning.
[0021] Working principle: Place the housing on the shelf 4. First, rotate the first knob 503 on both sides. The first adjusting threaded rod 502 pushes the horizontal clamping plate 504 inward, so that the first friction pad 505 abuts against the side of the housing, completing the fixation of the side of the housing. Then, rotate the second knob 508. The second adjusting threaded rod 507 pushes the vertical clamping plate 511 downward. If the surface of the housing is tilted at a certain angle, when the second friction pad 512 contacts the surface of the housing, the rotating plate 510 and the connecting block 509 will rotate accordingly, so that the angle of the vertical clamping plate 511 is consistent with the tilt angle. At the same time, the surface of the first friction pad 505 has a vertical groove, and the surface of the second friction pad 512 has a left-right directional groove. The groove effectively prevents the housing from shifting in the front and back directions through friction, effectively fixing the housing in all directions. The positioning pin 18 can accurately determine the fixed position of the housing through the laser scanning principle. After determining the position to be adjusted, a suitable adjusting head 16 is installed at the lower end of the adjusting box 15. The adjusting motor 9 drives the rotating threaded rod 10 to rotate, which can adjust the front and back positions of the I-shaped slider 8, the mounting bracket 12, the adjusting box 15 and the adjusting head 16. The adjusting push rod 17 can change the position of the adjusting box 15 and the adjusting head 16 in the left and right directions. Finally, the lifting push rod 3 changes the height difference between the adjusting head 16 and the housing, so that the adjusting head 16 abuts against the adjusting position and adjusts the parallelism.
