Description

Technical Field

[0001] The utility model belongs to the technical field of welding tooling, and particularly relates to a steel structure welding auxiliary tooling. Background Art

[0002] As Figure 4 shown in Figure 5 the figure, it is a schematic structural diagram of a steel structure straight ladder in the prior art. That is, in the prior art, the straight ladder 7 made of steel usually includes two ladder legs 71, and a plurality of tread bars 72 evenly distributed at equal intervals are arranged between the two ladder legs 71. Both ends of each tread bar 72 are fixedly connected to the ladder legs 71 by welding.

[0003] However, in the prior art, when welding the straight ladder 7, there is no auxiliary tooling that can position the straight ladder. In this way, when producing and processing the same batch of straight ladders, for each straight ladder, it is necessary to measure multiple times to determine the positions of the respective tread bars 72, so it is not convenient to weld and process the straight ladder. That is to say, the production efficiency of the straight ladder needs to be improved. Therefore, there are still drawbacks and deficiencies in the prior art. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a steel structure welding auxiliary tooling to solve the problems put forward in the above background art.

[0005] The technical solution adopted by the utility model to solve the above problems:

[0006] A steel structure welding auxiliary tooling includes two horizontally opposite rails. Two sets of position adjusting mechanisms that are horizontally opposite and can adjust positions along the length direction of the rails are installed between the two rails. The position adjusting mechanisms are perpendicular to the rails in the horizontal direction, and a plurality of first sliding members that can adjust positions along the length direction of the position adjusting mechanisms are installed on each set of position adjusting mechanisms. A positioning member is fixedly connected to each first sliding member. The positioning members each include a first U-shaped positioning plate fixedly connected to the first sliding member and arranged parallel to the position adjusting mechanism. The U-shaped openings of the first U-shaped positioning plates are all upward, and a first screw rod parallel to the rails and passing through the first U-shaped positioning plate is threadedly connected to the outside of each first U-shaped positioning plate. A second U-shaped positioning plate parallel to the rails is fixedly communicated with the inside of each first U-shaped positioning plate. The U-shaped openings of the second U-shaped positioning plates are all upward.

[0007] Further, the inner bottom surface of the second U-shaped positioning plate is higher than the inner bottom surface of the first U-shaped positioning plate.

[0008] Further, the inner bottom surface of the second U-shaped positioning plate is flush with the inner bottom surface of the first U-shaped positioning plate.

[0009] Further, two second sliding members are arranged on each guide rail. Each second sliding member includes an inverted U-shaped slide plate slidably connected to the guide rail. A second screw rod parallel to the position adjusting mechanism and passing through the inverted U-shaped slide plate is threadedly connected to the outer side of each inverted U-shaped slide plate. And the position adjusting mechanism is installed between two inverted U-shaped slide plates at the same end of the guide rail.

[0010] Further, each position adjusting mechanism includes a bearing plate horizontally arranged and perpendicular to the guide rail in the horizontal direction. Two ends of the bottom surface of the bearing plate are respectively fixedly connected to the inverted U-shaped slide plates. Two ends of the top surface of the bearing plate are fixedly connected with vertically distributed support plates. And two guide rods parallel to the bearing plate are fixedly connected between two support plates on each bearing plate. A plurality of the first sliding members capable of adjusting positions along the length direction of the guide rods are installed between the two guide rods.

[0011] Further, each first sliding member includes a slider. Two sides of the slider are respectively sleeved on the guide rods and slidably connected to the guide rods. And a third screw rod capable of abutting against the guide rod is threadedly connected between the outer side of the slider and the guide rod. The top surfaces of the sliders are respectively fixedly connected to a first U-shaped positioning plate and a second U-shaped positioning plate.

[0012] Further, both ends of each guide rod are connected to the support plate through a fourth screw rod.

[0013] Adopting the above technical solution, the beneficial effects of the present utility model are as follows:

[0014] When the present utility model is in use, the position of the guide rail is fixed. Before welding the straight ladder, the two groups of position adjusting mechanisms can be adjusted to appropriate positions and fixed according to the length of the tread bar. Then, according to the number and position of the tread bars, taking one end of the position adjusting mechanism as a reference, by adjusting the positions of the first sliding members, the positioning members can be respectively adjusted to appropriate positions and fixed. In this way, when welding the straight ladder, the ladder legs can be respectively placed between a plurality of first U-shaped positioning plates. And according to the reference position on the position adjusting mechanism, after aligning the two ladder legs, the positions of the ladder legs can be locked and fixed by using the first screw rod. Then, the tread bars are respectively placed between two oppositely arranged second U-shaped positioning plates. At this time, both ends of the tread bar will respectively abut against the ladder legs, and the distance between adjacent tread bars is equal, which is convenient for subsequent welding operations of the straight ladder. In this way, when producing and processing the same batch of straight ladders, it is possible to facilitate determining the positions of each tread bar on each straight ladder, so as to facilitate the welding process of the straight ladder and improve the production efficiency of the straight ladder.

Detailed implementation manners

[0021] To make the objectives, technical solutions and beneficial effects of the present utility model clearer, the following further describes the implementation manners of the present utility model in detail with reference to the drawings.

[0022] As Figures 1 to 3 shown, the present utility model provides a steel - structure welding auxiliary tooling. Specifically, when welding a steel - structure straight ladder as shown in Figure 4 and Figure 5 shown, the present utility model is an auxiliary tooling capable of positioning the straight ladder 7. That is, the straight ladder 7 includes rectangular ladder legs 71 and tread bars 72; and the present utility model includes two horizontally - arranged guide rails 6 opposite to each other. Specifically, in use, the positions of the guide rails 6 are fixed, and the specific setting method for fixing the positions of the guide rails 6 is as follows: Both sides of the bottom of each guide rail 6 are fixedly connected with mounting plates 2 parallel to and of the same length as the guide rail 6. A plurality of mounting through - holes 21 are vertically opened on each mounting plate 2 at equal intervals along the length direction of the mounting plate 2. In this way, when in use, the positions of the mounting plates 2 can be fixed by using connecting pieces such as anchor bolts, so as to fix the positions of the guide rails 6.

[0023] There are two sets of position adjustment mechanisms 3 installed between the two guide rails 6. The two sets of position adjustment mechanisms 3 are horizontally arranged opposite to each other and can adjust their positions along the length direction of the guide rails 6. The position adjustment mechanisms 3 are perpendicular to the guide rails 6 in the horizontal direction. Specifically, before welding the straight ladder 7, the two sets of position adjustment mechanisms 3 can be adjusted to appropriate positions according to the length of the tread bar 72 and then fixed. And several first sliding members 4 that can adjust their positions along the length direction of the position adjustment mechanism 3 are installed on each set of position adjustment mechanisms 3. A positioning member 1 is fixedly connected to each first sliding member 4. Specifically, after fixing the position of the position adjustment mechanism 3, according to the quantity and position of the tread bars 72, with one end of the position adjustment mechanism 3 as a reference, by adjusting the positions of the first sliding members 4, the positioning members 1 can be adjusted to appropriate positions and then fixed.

[0024] The positioning members 1 each include a first U-shaped positioning plate 11 fixedly connected to the first sliding member 4 and arranged parallel to the position adjustment mechanism 3. The U-shaped openings of the first U-shaped positioning plates 11 are all upward. Specifically, the width inside the first U-shaped positioning plate 11 is adapted to the width of the ladder leg 71. And a first screw rod 12 arranged parallel to the guide rail 6 and penetrating through the first U-shaped positioning plate 11 is threadedly connected to the outside of each first U-shaped positioning plate 11. Specifically, a first handwheel 13 is fixedly connected to the outer end of the first screw rod 12. The first handwheel 13 can facilitate the rotation of the first screw rod 12. A second U-shaped positioning plate 14 arranged parallel to the guide rail is fixedly communicated with the inner side of each first U-shaped positioning plate 11. The U-shaped openings of the second U-shaped positioning plates 14 are all upward. Specifically, the width inside the second U-shaped positioning plate 14 is adapted to the width of the tread bar 72. In this way, when welding the straight ladder 7, the ladder legs 71 can be respectively placed between several first U-shaped positioning plates 11. And according to the reference position on the position adjustment mechanism 3, after aligning the two ladder legs 71, the position of the ladder legs 71 can be locked and fixed by using the first screw rod 12, that is, by rotating the first screw rod 12, after the end of the first screw rod 12 away from the first handwheel 13 abuts against the ladder leg 71, the position of the ladder leg 71 can be locked and fixed. Then the tread bars 72 are respectively placed between two relatively arranged second U-shaped positioning plates 14. At this time, the two ends of the tread bar 72 will respectively abut against the ladder legs 71, and the distance between adjacent tread bars 72 is equal, which is convenient for subsequent welding operations on the straight ladder 7. In this way, when producing and processing the same batch of straight ladders, it is convenient to determine the positions of each tread bar 72 on each straight ladder 7, so as to facilitate the welding processing of the straight ladder 7 and improve the production efficiency of the straight ladder 7. In addition, after welding the top surface of the straight ladder 7 is completed, the first screw rod 12 can be loosened from the ladder leg 71, and then the straight ladder 7 can be removed, which is convenient for subsequent welding of other welding positions on the straight ladder 7.

[0025] When for Figure 4When welding the straight ladder 7 shown, that is, when there is a height difference at the welding position between the tread bar 72 and the ladder leg 71, the inner bottom surface of the second U-shaped positioning plate 14 is higher than the inner bottom surface of the first U-shaped positioning plate 11. Specifically, as Figure 4 shown, the height difference at the welding position between the tread bar 72 and the ladder leg 71 is H1, and the height difference between the inner bottom surface of the second U-shaped positioning plate 14 and the inner bottom surface of the first U-shaped positioning plate 11 is H2, and H2 = H1, which can facilitate the welding of the straight ladder 7 as Figure 4 shown.

[0026] When welding the straight ladder 7 as Figure 5 shown, that is, when the welding position between the tread bar 72 and the ladder leg 71 is flush, as Figure 1 and Figure 2 shown, the inner bottom surface of the second U-shaped positioning plate 14 is flush with the inner bottom surface of the first U-shaped positioning plate 11, which can facilitate the welding of the straight ladder 7 as Figure 5 shown.

[0027] The specific setting method for the position adjustment mechanism 3 to be able to adjust its position along the length direction of the guide rail 6 is as follows: As Figure 1 and Figure 3 shown, two second sliding members 5 are provided on each guide rail 6. Each second sliding member 5 includes an inverted U-shaped slide plate 51 slidably connected to the guide rail 6. A second screw rod 52 parallel to the position adjustment mechanism 3 and passing through the inverted U-shaped slide plate 51 is threadedly connected to the outside of the inverted U-shaped slide plate 51. Specifically, a second hand wheel 53 is fixedly connected to the end of the second screw rod 52 far from the guide rail 6, and the second hand wheel 53 can facilitate the rotation of the second screw rod 52; and the position adjustment mechanism 3 is installed between the two inverted U-shaped slide plates 51 at the same end of the guide rail 6. Specifically, in use, by rotating the second screw rod 52, after the end of the second screw rod 52 far from the second hand wheel 53 abuts against the guide rail 6, the position of the second sliding member 5 can be fixed, thereby being able to fix the position of the position adjustment mechanism 3; and when rotating the second screw rod 52 in the reverse direction, when the end of the second screw rod 52 far from the second hand wheel 53 is separated from the guide rail 6, the position of the second sliding member 5 can be adjusted along the length direction of the guide rail 6, thereby being able to adjust the position of the position adjustment mechanism 3 along the length direction of the guide rail 6, and after adjusting the position of the second sliding member 5, the position of the second sliding member 5 can be fixed again by using the second screw rod 52 to fix the position of the position adjustment mechanism 3.

[0028] The specific setting method of the position adjustment mechanism 3 is as follows: As Figures 1 to 3As shown in the figure, the position adjusting mechanism 3 includes a bearing plate 31 which is horizontally arranged and perpendicular to the guide rail 6 in the horizontal direction. Both ends of the bottom surface of the bearing plate 31 are fixedly connected to the inverted U-shaped sliding plate 51 respectively. Both ends of the top surface of the bearing plate 31 are fixedly connected with vertically distributed support plates 32. Specifically, before welding the straight ladder 7, when adjusting the position of the first sliding member 4, one of the support plates 32 can be used as a reference plate; when aligning the two ladder legs 71, one end of the ladder leg 71 can be abutted against the reference plate, so as to facilitate the alignment of the two ladder legs 71; and two guide rods 33 parallel to the bearing plate 31 are fixedly connected between the two support plates 32 on each bearing plate 31, and a number of the first sliding members 4 capable of adjusting the position along the length direction of the guide rods 33 are installed between the two guide rods 33. Specifically, in use, when adjusting the position of the first sliding member 4 along the length direction of the two guide rods 33, the position of the positioning member 1 can be adjusted.

[0029] The specific setting method of the first sliding member 4 is as follows: As Figures 1 to 3 shown in the figure, the first sliding member 4 includes a slider 41. Both sides of the slider 41 are sleeved on the guide rods 33 respectively and are slidably connected with the guide rods 33. And third screws 42 which can abut against the guide rods 33 are threadedly connected between the outer sides of the slider 41 and the guide rods 33. Specifically, the third screws 42 are arranged parallel to the guide rail 6 and are threadedly connected with the slider 41. One end of each third screw 42 penetrates through the slider 41, and the other end of each third screw 42 is fixedly connected with a third handwheel 43. The third handwheel 43 can facilitate the rotation of the third screw 42; in use, by rotating the third screw 42, after the end of the third screw 42 far from the third handwheel 43 abuts against the guide rod 33, the position of the first sliding member 4 can be fixed, so that the position of the positioning member 1 can be fixed; and when rotating the third screw 42 in the reverse direction, when the end of the third screw 42 far from the third handwheel 43 is separated from the guide rod 33, the position of the first sliding member 4 can be adjusted along the length direction of the guide rod 33, so that the position of the positioning member 1 can be adjusted. And after adjusting the position of the first sliding member 4, the position of the first sliding member 4 can be fixed by using the third screw 42 again to fix the position of the positioning member 1; in addition, the top surfaces of the sliders 41 are fixedly connected with the first U-shaped positioning plate 11 and the second U-shaped positioning plate 14 respectively, so as to ensure the connection strength between the first sliding member 4 and the positioning member 1.

[0030] Furthermore, as Figure 1 shown in Figure 3As shown, both ends of each guide rod 33 are connected to the support plate 32 through a fourth screw 34. Specifically, the fourth screw 34 is coaxially arranged with the guide rod 33 and is threadedly connected to the support plate 32. One end of the fourth screw 34 penetrates through the support plate 32 and is threadedly connected to the guide rod 33. A fourth handwheel 35 is fixedly connected to the other end of the fourth screw 34. The fourth handwheel 35 can facilitate the rotation of the fourth screw 34. During use, by rotating the fourth screw 34, the end of the fourth screw 34 away from the fourth handwheel 35 can be separated from the guide rod 33, so that it is convenient to disassemble and assemble the guide rod 33 between the two support plates 32. In addition, after removing the guide rod 33, it is also convenient to disassemble and assemble the first sliding member 4 and the positioning member 1 on the guide rod 33.
