Detailed Implementation

[0031] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0032] In one embodiment, such as Figures 1-8 As shown, a side door frame spot welding fixture includes a welding table 1, which is provided with a fixing area 2 and an adjustment area 3. The fixing area 2 is used to fix and limit the adjacent sides of the side door frame; the adjustment area 3 is used to adjust and limit the other adjacent sides of the side door frame.

[0033] The adjustment zone 3 is equipped with guide rails 4 and slide plates 6. Several guide rails 4 are fixedly connected to the upper surface of the welding table 1. Two guide rails 4 are slidably connected to the slide plate 6. The upper surfaces of the welding table 1 and the slide plate 6 are equipped with limit structure 1 7 and limit structure 2 8. The upper surface of the welding table 1 is equipped with limit structure 3 9, which is located in the fixed zone 2. Several bolt holes are opened on the upper surface of the welding table 1 located in the adjustment zone 3. The slide plate 6 is opened with holes corresponding to the bolt holes. Several door frame placement racks are installed on the upper surfaces of the welding table 1 and the slide plate 6 by bolts.

[0034] Place the two sides of the side door frame to be welded on the door frame placement rack located in the fixed area 2. Adjust the sliding plate 6 according to the size of the truck door frame. After adjustment, fix it with bolts to facilitate the limiting and fixing of side door frames of different sizes.

[0035] In one embodiment, the limiting structure 7 includes a mounting base 14, a connecting rod 10, and an adjusting bolt 11. The upper surfaces of the welding table 1 and the slide plate 6 are both bolted with mounting base 14. The upper surface of the mounting base 14 is connected to the connecting rod 10 via a pin. The connecting rod 10 is connected to the connecting rod 12 via a pin. The connecting rod 12 is connected to the sliding rod 15 via a pin. The upper surface of the mounting base 14 is fixedly connected to the fixing cylinder 13. The sliding rod 15 is slidably connected to the inner wall of the fixing cylinder 13. One end of the sliding rod 15 is provided with an adjusting bolt 11. The connecting rod 10 is connected to a rotating handle.

[0036] Limiting structure 1 7 and limiting structure 3 9 are used to limit the side door frame in the lateral direction, and limiting structure 3 9 is used to limit the side door frame in the longitudinal direction.

[0037] When using the limiting structure 7, by holding the rotating handle, the connecting rod 10 is rotated. The rotation of the connecting rod 10 drives the connecting rod 2 12 to move forward. The connecting rod 2 12 drives the sliding rod 15 to move forward, so that the adjusting bolt 11 part abuts against the side wall of the side door frame, thus completing the lateral positioning of the side door frame.

[0038] Adjusting bolt 11 can be rotated and adjusted according to the position of the side door frame to fit different sizes of side door frames.

[0039] When the adjusting bolt 11 is in the fixed position, one section of the connecting rod 10 and the sliding rod 15 are on the same horizontal plane. Therefore, when the lateral pressure is transmitted from the sliding rod 15 to the connecting rod 10, the connecting rod 10 cannot rotate, thus achieving the self-locking function. However, when unlocking, the locking state can be released by rotating the connecting rod 10 and pulling the connecting rod 12, which in turn pulls the sliding rod 15. This makes it quick and convenient to use.

[0040] In one embodiment, the limiting structure 28 includes a rotating plate 17, a connecting rod 4 18, and a fixing plate 1 20. The upper surfaces of the welding table 1 and the sliding plate 6 are bolted with a mounting base 21. The upper surface of the mounting base 21 is bolted with a fixing plate 1 20. The fixing plate 1 20 is connected to a connecting rod 3 16 and a connecting rod 4 18 by a pin. The connecting rod 4 18 is connected to the rotating plate 17 by a pin. The rotating plate 17 and the connecting rod 3 16 are connected by a pin. The connecting rod 3 16 is connected with a rotating handle. The connecting rod 4 18 is provided with an adjusting bolt 2 19. The adjusting bolt 2 19 is provided with an abutment block.

[0041] When using the second limiting structure 8, the connecting rod 16 is rotated by hand-held rotating handle. The rotation of the connecting rod 16 drives the rotating plate 17 to rotate, and the rotating plate 17 drives the fourth connecting rod 18 to rotate, so that the abutting block on the adjusting bolt 19 abuts against the upper surface of the side door frame, thus completing the longitudinal positioning of the side door frame.

[0042] Adjusting bolt 219 can be rotated and adjusted according to the position of the side door frame to fit different sizes of side door frames;

[0043] When adjusting bolt 2 19 is in the fixed position, rotating plate 17 and adjusting bolt 2 19 are in the same vertical direction. Therefore, when longitudinal pressure is transmitted from adjusting bolt 2 19 to connecting rod 4 18, for connecting rod 4 18 to rotate, rotating plate 17 must move upward. However, due to the restriction of connecting rod 3 16, rotating plate 17 cannot move upward, so connecting rod 4 18 cannot rotate, thus achieving the self-locking function. However, when unlocking, connecting rod 3 16 can be rotated. At this time, rotating plate 17 rotates accordingly, and rotating plate 17 no longer maintains the same vertical direction as adjusting bolt 2 19. Connecting rod 4 18 can then rotate accordingly, achieving quick unlocking. It is quick and convenient to use.

[0044] In one embodiment, a limiting block 22 is fixedly connected to the side wall of the fixing plate 20. The limiting block 22 is used to limit the rotation angle of the rotating link 16.

[0045] In one embodiment, the limiting structure 3 9 includes a fixed cylinder 2 24, a sliding rod 2 25, and a fixed plate 2 28. The upper surface of the welding table 1 is bolted with a mounting seat 3 23. The upper surface of the mounting seat 3 23 is bolted with the fixed cylinder 2 24 and the fixed plate 2 28. The fixed plate 2 28 is connected to a connecting rod 5 27 via a pin. The connecting rod 5 27 is connected to an arc-shaped connecting rod 29 via a pin. The arc-shaped connecting rod 29 is connected to the sliding rod 2 25 via a pin. The sliding rod 2 25 is slidably connected to the inner wall of the fixed cylinder 2 24. One end of the sliding rod 2 25 is provided with an adjusting bolt 3 26. The connecting rod 5 27 is connected to a rotating handle.

[0046] When using the limiting structure 39, the connecting rod 527 is rotated by holding the rotating handle. The rotation of the connecting rod 527 drives the arc connecting rod 29 to rotate. The arc connecting rod 29 drives the sliding rod 25 to move forward, so that the adjusting bolt 326 abuts against the side wall of the side door frame, further positioning the side door frame laterally and improving the stability of the side door frame positioning.

[0047] When adjusting bolt 3 26 is in the fixed position, arc-shaped connecting rod 29, sliding rod 25, and connecting rod 5 27 are in the same horizontal direction. Therefore, when lateral pressure is transmitted from sliding rod 25 to connecting rod 5 27, connecting rod 5 27 cannot rotate, thus achieving the self-locking function. However, when unlocking, connecting rod 5 27 can be rotated. At this time, arc-shaped connecting rod 29 rotates accordingly, and arc-shaped connecting rod 29, sliding rod 25, and connecting rod 5 27 no longer maintain the same horizontal direction. Sliding rod 25 can retract, achieving quick unlocking. It is quick and convenient to use.

[0048] In one embodiment, a plurality of limiting blocks 5 are bolted to the upper surface of the welding table 1, and the limiting blocks 5 are located within the adjustment area 3.

[0049] The above embodiments disclose a side door frame spot welding fixture, the specific working principle and process of which are as follows:

[0050] S1: First, place the two sides of the side door frame to be welded on the door frame placement rack located in the fixed area 2. Adjust the sliding plate 6 according to the size of the truck door frame. After adjustment, fix it with bolts to facilitate the limiting and fixing of side door frames of different sizes.

[0051] S2: After the position of the slide plate 6 is adjusted, the door frame to be processed needs to be limited and fixed. During this process, the limiting structure 1 7, limiting structure 2 8, and limiting structure 3 9 need to be manually controlled.

[0052] Limiting structure 1 7 and limiting structure 3 9 are used to limit the side door frame in the lateral direction, and limiting structure 3 9 is used to limit the side door frame in the longitudinal direction.

[0053] When using the limiting structure 7, by holding the rotating handle, the connecting rod 10 is rotated. The rotation of the connecting rod 10 drives the connecting rod 2 12 to move forward. The connecting rod 2 12 drives the sliding rod 15 to move forward, so that the adjusting bolt 11 part abuts against the side wall of the side door frame, thus completing the lateral positioning of the side door frame.

[0054] Adjusting bolt 11 can be rotated and adjusted according to the position of the side door frame to fit different sizes of side door frames;

[0055] When the adjusting bolt 11 is in the fixed position, one section of the connecting rod 10 is on the same horizontal plane as the sliding rod 15. Therefore, when the lateral pressure is transmitted from the sliding rod 15 to the connecting rod 10, the connecting rod 10 cannot rotate, thus achieving the self-locking function. However, when unlocking, the locking state can be released by rotating the connecting rod 10 and pulling the connecting rod 12, which in turn pulls the sliding rod 15. This makes it quick and convenient to use.

[0056] When using the second limiting structure 8, the connecting rod 16 is rotated by hand-held rotating handle. The rotation of the connecting rod 16 drives the rotating plate 17 to rotate, and the rotating plate 17 drives the fourth connecting rod 18 to rotate, so that the abutting block on the adjusting bolt 19 abuts against the upper surface of the side door frame, thus completing the longitudinal positioning of the side door frame.

[0057] Adjusting bolt 219 can be rotated and adjusted according to the position of the side door frame to fit different sizes of side door frames;

[0058] When adjusting bolt 2 19 is in the fixed position, rotating plate 17 and adjusting bolt 2 19 are in the same vertical direction. Therefore, when longitudinal pressure is transmitted from adjusting bolt 2 19 to connecting rod 4 18, for connecting rod 4 18 to rotate, rotating plate 17 must move upward. However, due to the restriction of connecting rod 3 16, rotating plate 17 cannot move upward, so connecting rod 4 18 cannot rotate, thus achieving the self-locking function. However, when unlocking, connecting rod 3 16 can be rotated. At this time, rotating plate 17 rotates accordingly, and rotating plate 17 no longer maintains the same vertical direction as adjusting bolt 2 19. Connecting rod 4 18 can then rotate accordingly, achieving quick unlocking. It is quick and convenient to use.

[0059] When using the limiting structure 39, the connecting rod 527 is rotated by holding the rotating handle. The rotation of the connecting rod 527 drives the arc connecting rod 29 to rotate. The arc connecting rod 29 drives the sliding rod 25 to move forward, so that the adjusting bolt 326 abuts against the side wall of the side door frame, further positioning the side door frame laterally and improving the stability of the side door frame positioning.

[0060] When adjusting bolt 3 26 is in the fixed position, arc-shaped connecting rod 29, sliding rod 25, and connecting rod 5 27 are in the same horizontal direction. Therefore, when lateral pressure is transmitted from sliding rod 25 to connecting rod 5 27, connecting rod 5 27 cannot rotate, thus achieving the self-locking function. However, when unlocking, connecting rod 5 27 can be rotated. At this time, arc-shaped connecting rod 29 rotates accordingly, and arc-shaped connecting rod 29, sliding rod 25, and connecting rod 5 27 no longer maintain the same horizontal direction. Sliding rod 25 can retract, achieving quick unlocking. It is quick and convenient to use.

[0061] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
