DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1-4 The utility model provides a technical solution: a window frame clamp for door and window production, comprising a base plate 1, a positioning clamp 2 is slidably connected to the upper surface of the base plate 1, and limiting plates 3 are welded on both sides of the base plate 1. A driving structure 4 for pushing the positioning clamp 2 to move toward the limiting plates 3 is arranged above the base plate 1, and extension arms 5 for facilitating the positioning of the window frame are arranged on both sides of the limiting plates 3. A distance adjustment structure 6 for positioning the welding position of the window frame is arranged at one end of the base plate 1;

[0023] By setting the distance adjustment structure 6, the clamp can also be used when the frame of the window frame needs to be welded into a T shape. Specifically, one end of one frame is pressed against the positioning rod 603, and one end of the other frame is welded to the side wall of the frame. The position of the positioning rod 603 is convenient for determining the extension length of the frame.

[0024] The extension arm 5 includes a pad 501, an extension rod 502 is welded to one side of the pad 501, one end of the extension rod 502 is slidably connected in the limit plate 3, a positioning knob 503 is threadedly connected above the limit plate 3, the bottom end of the positioning knob 503 is pressed against the outer wall of the extension rod 502, and a clamp 7 for pressing the window frame is fixed above the pad 501.

[0025] By setting the clamping clamp 7 and manually opening the clamping clamp 7, when the window frame is placed on the pad 501, the clamping clamp 7 is released, and the clamping clamp 7 is pressed against the top of the window frame under the action of the torsion spring 703. This structure can ensure that the bottom of the window frame is in close contact with the substrate 1 during welding, so that the weld is aligned and the welding quality is improved.

[0026] The clamping clamp 7 includes a clamping plate 701 and a fixing plate, the fixing plate is fixedly connected to the backing plate 501 by screws, a rotating rod 702 is fixed to one end of the clamping plate 701, both ends of the rotating rod 702 are rotatably connected in the fixing plate, and a torsion spring 703 is sleeved on the outer wall of the rotating rod 702.

[0027] The pad 501 is arranged in an L shape, and the two groups of extension rods 502 are arranged orthogonally on the extension line.

[0028] A pressing protrusion 704 is disposed on the lower surface of the other end of the clamping plate 701 , and a window frame pressing position 705 is formed between the pressing protrusion 704 and the upper surface of the horizontal plate of the backing plate 501 .

[0029] The driving structure 4 includes a fixing seat 401 and a screw 402. The fixing seat 401 is fixedly connected to the base plate 1 by screws. The screw 402 passes through the fixing seat 401 and is threadedly connected to the fixing seat 401. One end of the screw 402 is rotatably connected to the positioning clamp 2. Positioning plates 403 are provided on both sides of the positioning clamp 2.

[0030] After the screw rod 402 is rotated, the thread penetrates into the fixing seat 401, pushing the positioning clamp 2 to slide on the surface of the substrate 1, so that the positioning clamp 2 approaches the two limiting plates 3 to clamp the two frames.

[0031] The distance adjustment structure 6 includes a slider 601 and a slide groove 602. The slider 601 is slidably connected in the slide groove 602. A positioning rod 603 is welded to the top of the slider 601. One side of the slider 601 is rotatably connected to an adjustment rod 604. The adjustment rod 604 passes through one side of the substrate 1 and is threadedly connected to the substrate 1.

[0032] After the adjusting rod 604 is rotated, the slider 601 moves in the slide groove 602, driving the positioning rod 603 to move. This structure is convenient for determining the extension length of one end of the window frame and for locating the welding position.

[0033] The upper surface of the substrate 1 is provided with a groove 8, and a mounting groove 9 is provided in the groove 8 for facilitating the fixing of the substrate 1. By providing the mounting groove 9, the substrate 1 can be fixed on a workbench by screws for use.

[0034] When in use, place the two window frames in the gap between the positioning plate 403 and the limiting plate 3. If the window frame is long, manually pull the pad outwards and open the clamp 701 to place the window frame on the window frame pressing position 705. After releasing the clamp 701, the pressing clamp 7 is pressed against the top of the window frame under the action of the torsion spring 703. Manually turn the positioning knob 503 to make the bottom end of the positioning knob 503 press against the outer wall of the extension rod 502 to position the pad. At this time, one end of the window frame is located on the substrate 1 and the other end is pressed against the pad 501. Manually press the splicing corner of the window frame so that the welding position of the window frame is flush and will not warp. The clamp can not only position window frames of different lengths, heights and widths, but also ensure that the bottom of the window frame is in close contact with the substrate 1 during welding, so that the weld is aligned neatly and the welding quality is improved.
