Description

Technical Field

[0001] This utility model belongs to the field of civil defense door processing technology, and in particular relates to a welding device for civil defense door processing. Background Technology

[0002] Civil defense doors are the entrances and exits of civil protection projects. During the manufacturing process of some civil defense doors, four strip steel plates need to be welded into a frame. Since the edges of the four strip steel plates need to be aligned before welding, in actual operation, they are often aligned manually before welding, resulting in inaccurate splicing and welding of steel plates. Although there are some auxiliary mechanisms, it is inconvenient to connect them when welding steel plates of different lengths and widths, which affects the welding efficiency. Utility Model Content

[0003] The technical problem this invention aims to solve is that when welding steel plates of different lengths and widths, two pairs of strip steel plates of different lengths are required. Existing auxiliary mechanisms are inconvenient to connect, which affects welding efficiency.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a welding device for processing air-raid shelter doors, comprising a fixed frame, the top of the fixed frame having stroke holes arranged in a cross-shaped array, guide rods fixedly connected between the inner walls of the stroke holes, and a slider horizontally sliding on the guide rods, and further comprising...

[0005] A placement component, located on the top of the slider, includes a placement seat, which is fixedly connected to the top of the slider. The top of the placement seat is vertically connected to an adjusting rod threadedly. The lower end of the adjusting rod is fixedly connected to a clamping plate. The top of the clamping plate is fixedly connected to symmetrically distributed limiting rods. The upper end of the limiting rods vertically penetrates the top of the placement seat and is slidably connected to it.

[0006] The stroke adjustment assembly, located inside the fixed frame, includes a slant rod. The upper end of the slant rod is hinged to the bottom of the slider, and the lower end of the slant rod is hinged to a block. A vertical rod is vertically and slidably mounted on the block. The vertical rod has linearly arranged positioning grooves, and the block has positioning holes that are adapted to the positioning grooves.

[0007] The docking assembly, located at the lower end of the vertical rod, includes a connecting plate, which is fixedly connected to the lower end of the vertical rod. An adjustment mechanism is provided at the bottom of the fixing frame, which is used to adjust the vertical height of the connecting plate.

[0008] Furthermore, the clamp is L-shaped and made of metal, and the inner wall of the clamp is provided with a magnetic suction plate that attracts it.

[0009] Furthermore, the adjustment mechanism includes a connecting rod and an adjustment block. The inner bottom wall of the fixed frame is provided with symmetrically distributed vertical plates. A servo motor is fixedly installed on the outer wall of one set of vertical plates. The output end of the servo motor is fixedly connected to a bidirectional screw. The other end of the bidirectional screw is rotatably connected to the outer wall of another set of vertical plates. The adjustment block is threadedly connected to the bidirectional screw and is symmetrically distributed. The connecting rod is hinged between the top of the adjustment block and the bottom of the connecting plate.

[0010] Furthermore, the placement base is C-shaped, the vertical rod is T-shaped, the guide rod is cuboid, and the adjusting rod is T-shaped.

[0011] Furthermore, the bottom wall of the fixed frame is provided with symmetrically distributed limiting strips, and the adjusting block slides horizontally on the limiting strips.

[0012] Furthermore, the outer wall of the slider is in contact with the inner wall of the travel hole.

[0013] The beneficial effects of this utility model after adopting the above structure are as follows:

[0014] (1) Adjusting the position of the two blocks on the vertical rod can make appropriate adjustments to the initial position of each set of placement seats, and can also adjust the distance between the two opposite placement seats to make it suitable for strip steel plates of different lengths;

[0015] (2) The clamping plate can be moved down to press and position the strip steel plate. The magnetic suction plate can reduce the gap between the clamping plate and the strip steel plate, ensuring the stability during placement.

[0016] (3) The blocks move towards each other under the action of the limiting strip, which in turn causes the connecting rod to move the connecting plate down. The slider slides laterally on the guide rod under the action of the inclined rod until the strip steel plates are aligned, and then the welding operation can be carried out.

[0024] like Figure 1-2 As shown, a welding device for processing air defense doors includes a fixed frame 1. The top of the fixed frame 1 is provided with stroke holes 2, which are arranged in a cross-shaped array. A guide rod 3 is fixedly connected between the inner walls of the stroke holes 2. A slider 4 is horizontally slidably provided on the guide rod 3. The guide rod 3 is arranged in a cuboid shape. The outer wall of the slider 4 is in contact with the inner wall of the stroke hole 2. The device also includes a placement component, a stroke adjustment component, and a docking component.

[0025] like Figure 1-4 As shown, to facilitate the placement and positioning of each strip of steel plate, a placement assembly is located on the top of the slider 4, including a placement seat 5. The placement seat 5 is fixedly connected to the top of the slider 4 and is C-shaped. The top of the placement seat 5 is vertically connected to an adjusting rod 6, which is T-shaped. The lower end of the adjusting rod 6 is fixedly connected to a clamping plate 7. The top of the clamping plate 7 is fixedly connected to symmetrically distributed limiting rods 8. The upper end of the limiting rods 8 vertically penetrates the top of the placement seat 5 and is slidably connected to it. The clamping plate 7 is L-shaped and made of metal. The inner wall of the clamping plate 7 is provided with a magnetic suction plate 15 that attracts it. When the strip of steel plate is placed inside the placement seat 5, the adjusting rod 6 is turned to make the clamping plate 7 move down under the limiting action of the limiting rods 8, thus pressing and positioning the strip of steel plate. The magnetic suction plate 15 is attracted to the clamping plate 7, which can reduce the gap between the clamping plate 7 and the strip of steel plate.

[0026] like Figure 1-5As shown, in order to adjust the stroke after placing strip steel plates of different lengths, the stroke adjustment component is located inside the fixed frame 1, including a diagonal rod 9. The upper end of the diagonal rod 9 is hinged to the bottom of the slider 4, and the lower end of the diagonal rod 9 is hinged to a block 10. A vertical rod 11 is vertically and slidably mounted on the block 10. The vertical rod 11 is T-shaped and has linearly arranged positioning grooves 12. The block 10 has positioning holes 13 that are adapted to the positioning grooves 12. The positions of the two blocks 10 on the vertical rod 11 are adjusted and the bolts are screwed into the positioning holes 13 and positioning grooves 12 for positioning, thereby allowing appropriate adjustment of the initial position of each set of placement seats 5.

[0027] like Figure 1-3 As shown, in order to connect the various strip steel plates, a connecting assembly is located at the lower end of the vertical rod 11, including a connecting plate 14. The connecting plate 14 is fixedly connected to the lower end of the vertical rod 11. An adjustment mechanism is provided at the bottom of the fixing frame 1. The adjustment mechanism is used to adjust the vertical height of the connecting plate 14. The adjustment mechanism includes a connecting rod 16 and an adjusting block 17. The bottom wall of the fixing frame 1 is provided with symmetrically distributed vertical plates 18. A servo motor 19 is fixedly installed on the outer wall of a set of vertical plates 18. The output end of the servo motor 19 is fixedly connected to a bidirectional screw 20. The other bidirectional screw 20... The end is rotatably connected to the outer wall of another set of vertical plates 18. The adjusting block 17 is threadedly connected to the bidirectional screw 20 and is symmetrically distributed. The connecting rod 16 is hinged between the top of the adjusting block 17 and the bottom of the connecting plate 14. The inner bottom wall of the fixing frame 1 is provided with symmetrically distributed limiting strips 21. The adjusting block 17 slides horizontally on the limiting strips 21. Under the action of the limiting strips 21, the adjusting block 17 moves towards each other, thereby causing the connecting rod 16 to drive the connecting plate 14 to move down. The slider 4 slides laterally on the guide rod 3 under the action of the inclined rod 9 until the strip steel plates are aligned.

[0028] In practical use, according to the width and length of the air-raid shelter door to be welded, adjust the position of the two blocks 10 on the vertical rod 11 and screw them into the positioning holes 13 and positioning grooves 12 for positioning. Then, the initial position of each set of placement seats 5 can be adjusted appropriately. Then, place the strip steel plates inside each placement seat 5, and turn the adjusting rod 6 to make the clamping plate 7 move down under the limiting action of the limiting rod 8 to press and position the strip steel plates. The magnetic suction plate 15 can reduce the gap between the clamping plate 7 and the strip steel plates to ensure the stability during placement. Then, turn on the servo motor 19 to make the bidirectional screw 20 rotate. The adjusting block 17 moves towards each other under the action of the limiting strip 21, which causes the connecting rod 16 to drive the connecting plate 14 to move down. The slider 4 slides laterally on the guide rod 3 under the action of the inclined rod 9 until each strip steel plate is aligned, and then the welding operation can be carried out.
