Description

Technical Field

[0001] The present application relates to the technical field of steel plate welding alignment mechanisms, and specifically discloses an alignment adjustment mechanism for steel plate welding. Background Art

[0002] In the process of steel structure processing, the welding process of steel plates is often involved. The angles, widths, lengths and thicknesses of welded steel plates used in different steel structures are different.

[0003] In the traditional steel plate welding process, a welding platform is often used to support the steel plate to be welded, and the welding platform is used to carry and position the welded parts to facilitate the welding process. For the steel plate welding process applied in the same plane, the top end face of the welding platform is a plane, and usually a number of through holes or threaded holes are opened on the welding platform. A fixing structure for clamping and fixing the steel plate to be welded is installed by bolt connection. At the same time, the fixing structure is used as an adjustment structure to adjust the position of the adjacent end of the steel plate to be welded, so that the ends of the two steel plates to be welded are aligned.

[0004] However, the preparation work before welding steel plates not only needs to ensure that the steel plates of the two steel plates to be welded reach the predetermined position, but also needs to ensure that the steel plates reach the predetermined height. In particular, the welding ends of some steel plates need to be raised to leave the welding platform surface. Therefore, it is necessary to place a pad on the welding platform inside the welding ends of the steel plates to raise the steel plates. In the prior art, the fixing structure usually presses the steel plates on the welding platform to fix the steel plates. However, there is no fixing structure that can adjust the height of the steel plates while tightening the steel plates.

[0005] Therefore, in view of this, the inventor provides an alignment adjustment mechanism for steel plate welding to solve the above-mentioned problem. Utility Model Content

[0006] The utility model aims to solve the problem that in the traditional steel plate welding process, there is no fixed structure which can not only press the steel plate tightly but also adjust the height of the welding end of the steel plate.

[0007] In order to achieve the above-mentioned purpose, the basic scheme of the utility model provides an alignment and adjustment mechanism for steel plate welding, including a positioning plate detachably connected to the welding plate, a clamping plate slidably arranged on the positioning plate and used to clamp the steel plate, a control structure arranged on the positioning plate and used to control the position of the clamping plate, and a height adjustment seat arranged on the positioning plate and used to raise the steel plate.

[0008] Furthermore, the positioning plate comprises a positioning main board and a positioning connector which is arranged on the positioning main board and is detachably connected to the welding plate.

[0009] Furthermore, the positioning main plate is provided with a positioning sub-plate for supporting and connecting the clamping plate.

[0010] Furthermore, a guide groove is provided on the positioning sub-plate, and the clamping plate includes a horizontal portion which fits the end face of the positioning sub-plate and slides on the end face of the positioning sub-plate, and an inclined portion which is obliquely fixed to the inner side of the horizontal portion and can be abutted against the edge of the steel plate. A guide slide plate which is slidably connected to the guide groove is provided at the bottom end of the horizontal portion.

[0011] Furthermore, a cushion block is fixedly connected to the inner side of the inclined portion, and a plurality of grooves are formed on the cushion block at equal intervals.

[0012] Furthermore, an adjustment slot is provided on the inner side of the positioning main board, and a toggle slot connected to the adjustment slot is provided on the other side of the positioning main board. The height adjustment seat includes an inclined pad that is slidably connected in the adjustment slot and used to lift the steel plate, a toggle rod that is fixed on the inclined pad and slidably connected in the toggle slot, and a spring that is fixed between the toggle rod and the toggle slot and pushes the inclined pad outward.

[0013] The principle and effect of this scheme are:

[0014] 1. Compared with the prior art, the utility model presses the edge of the steel plate by means of a clamping plate arranged on the positioning plate, and simultaneously presses the edges on both sides of the steel plate to press the steel plate against the welding plate, and aligns the edges on both sides of the two steel plates to be welded.

[0015] 2. Compared with the prior art, the utility model can adjust the height of the steel plate through the height adjustment seat when aligning the two side edges of the steel plate, so that the heights of the two steel plates to be welded are aligned or any one of the steel plates reaches a predetermined height, which solves the problem that in the traditional steel plate welding process, there is no fixed structure that can both press the steel plate and adjust the height of the welding end of the steel plate.

[0016] 3. Compared with the prior art, the utility model uses a spring to push the lever and the inclined pad outward, so that the lever is lowered to the end of the driving slot, and the inclined pad is pushed out of the adjustment slot. When the positioning main board is clamped on the outside of the steel plate, the extension amount of the inclined pad and the corresponding inclined height position can be adjusted by moving the lever inward, and then the bottom edge of the steel plate is placed on the inclined pad to adjust the height of the steel plate on that side. When the steel plate does not need to be raised, the lever and the inclined pad are completely slid inward, and the steel plate can be placed horizontally on the welding plate. At the same time, due to the outward pushing effect of the spring, the outer end of the inclined pad will always be against the steel plate, and the upper clamping plate can be used to further fix the steel plate.

[0021] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the specific implementation method, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.

[0022] The reference numerals in the drawings of the specification include: welding plate 1, positioning main plate 2, positioning sub-plate 3, clamping plate 4, second nut 5, steel plate 6, connecting platform 7, second threaded column 8, inclined pad 9, and shift rod 10.

[0023] An alignment adjustment mechanism for steel plate welding, for example Figure 1 , Figure 2 and Figure 3 As shown:

[0024] It includes a positioning plate installed on the welding plate 1, a clamping plate 4 installed on the positioning plate, a control structure installed on the positioning plate and used to control the position of the clamping plate 4, and a height adjustment seat installed on the positioning plate and used to raise the steel plate 6. In this embodiment, a plurality of main positioning holes are distributed in a matrix on the welding plate 1.

[0025] The positioning plate comprises a positioning main board 2 and a positioning connector installed on the positioning main board 2. A secondary positioning hole of the same diameter as the main positioning hole is opened on the positioning main board 2, and the positioning connector comprises a first threaded column and a first nut installed at both ends of the first threaded column. When the secondary positioning hole on the positioning main board 2 is aligned with a main positioning hole, the first threaded column can be inserted into the secondary positioning hole, the bottom end of the first threaded column passes through the main positioning hole and is connected to a first nut, and the top end of the first threaded column is connected to another first nut, and the first nuts at both ends are screwed inward to clamp the positioning main board 2 on the welding plate 1.

[0026] A positioning sub-plate 3 for supporting and connecting the clamping plate 4 is also fixedly installed on the top of the positioning main plate 2, and two transverse guide grooves are opened on the positioning sub-plate 3. In this embodiment, the clamping plate 4 includes a horizontal part that fits on the end face of the positioning sub-plate 3 and can slide on the end face of the positioning sub-plate 3, and an inclined part that is welded obliquely to the inner end of the horizontal part and can abut against the edge of the steel plate 6. Two guide slides that can slide in the guide grooves are integrally formed at the bottom end of the horizontal part. A pad is also fixedly installed on the inner side of the inclined part, and a number of grooves are opened on the pad at equal distances. The edges of the steel plate 6 can be placed in the grooves accordingly, and the grooves abut against the two sides of the edge of the steel plate 6 respectively. The edge of the steel plate 6 can also be directly abutted by the end face of the pad.

[0027] The control structure includes a control board fixedly mounted on the positioning main board 2, a second threaded column 8 mounted on the control board and capable of rotation and sliding, and a second nut 5 mounted on the second threaded column 8 on the outside of the control board. A connecting platform 7 is also welded on the inner side of the clamping plate 4, a rotating hole is formed on the connecting platform 7, and a circle of closed limiting ring groove is formed in the inner layer of the rotating hole. A rotating platform extending into the rotating hole is integrally formed at the right end of the second threaded column 8, and a limiting ring platform extending into the limiting ring groove and capable of sliding therein is integrally formed on the outer wall of the rotating platform.

[0028] like Figure 2 and Figure 3 As shown, a transverse adjustment slot is also provided inside the positioning main board 2, and a wave slot connected to the adjustment slot is provided inwardly on the front end surface of the positioning main board 2. The height adjustment seat includes an inclined pad 9 installed in the adjustment slot and can slide out of the adjustment slot, a lever 10 welded on the inclined pad 9 and extending into the toggle slot, and a spring fixedly installed between the lever 10 and the toggle slot and used to push the inclined pad outward. The height of the inclined pad 9 gradually decreases in the direction of sliding outward. When not in use, the inclined pad 9 extends out of the adjustment slot.

[0029] When the utility model is used, a set of alignment adjustment mechanisms is first installed on the welding plate 1. During the welding process of the steel plate 6, two welding plates 1 are needed to fix one steel plate 6 respectively. The alignment adjustment mechanisms pre-installed on the two welding plates 1 are aligned, and then another set of alignment adjustment mechanisms are respectively installed on the other side of the steel plate 6.

[0030] After the alignment adjustment mechanism is installed on both sides of the steel plate 6, the positions of the second threaded column 8 and the lever 10 on the same side are adjusted respectively, and they need to be adjusted at the same time. Specifically, the height of the steel plate 6 to be welded can be controlled by sliding the lever 10 in the wave slide. After adjusting to the predetermined height, the second threaded column 8 is screwed inward and fixed by the second nut 5 to make the pad on the inner side of the clamping plate 4 press against the edge of the steel plate 6 to fix the steel plate 6. After that, the other side of the steel plate 6 is fixed, and the fixing method and steps are the same. At the same time, after the fixing is completed, the spring pushes outward, and the inclined pad 9 will always be against the steel plate 6, and the upper clamping plate 4 can be used to further fix the steel plate 6.
