Technical Field

[0001] The utility model relates to the technical field of assembling of sheet standard sections, in particular to a welding tooling for welding sheet standard sections into a whole piece. Background Art

[0002] Due to the convenient transportation and low transportation cost of tower crane sheet standard sections, the demand for sheet standard sections in the construction industry is continuously increasing, and its production speed and product quality are related to the development of the entire construction industry.

[0003] The sheet standard section 100 mainly includes main limbs 101, diagonal web members 105, connecting plates 106 and fish tail plates 102. As Figure 1 shown, both ends of the diagonal web member 105 are respectively connected to the main limb 101 and the connecting plate 106 to form a stable triangular structure. The fish tail plate 102 is welded to the end of the main limb 101, and an installation hole 103 is provided on the fish tail plate 102, and a connection hole 104 is provided on the connecting plate 106. Due to its installation characteristics, the size of each single piece of this standard section, especially the length of the main limb on the single piece and the positional accuracy of each connection and positioning hole, must be very precise and standard, with high interchangeability. Therefore, a welding tooling for welding sheet standard sections into a whole piece is provided. Summary of the Utility Model

[0004] Aiming at the deficiencies existing in the prior art, the utility model provides a welding tooling for welding sheet standard sections into a whole piece.

[0005] The technical solution for the utility model to solve the above technical problems is as follows:

[0006] A welding tooling for welding sheet standard sections into a whole piece includes a welding platform, and a first positioning part, a second positioning part and a third positioning part are arranged on the welding platform; the first positioning part is used for positioning the main limb, the second positioning part is used for positioning the connecting plate, and the third positioning part is used for positioning the diagonal web member.

[0007] By adopting the above technical solution, the main limb is positioned by the first positioning part, the connecting plate is positioned by the second positioning part, and the diagonal web member is positioned by the third positioning part, so as to achieve the purpose of positioning each structure of the sheet standard section, and then each structure is welded in sequence to achieve the purpose of welding the whole sheet standard section. This solution does not require repeated positioning. After all the parts are positioned, they (the whole piece) are welded, which is simple and convenient.

[0008] Further, the first positioning portion includes first positioning plates disposed on the welding platform. There are two first positioning plates, which are respectively located at both ends of the welding platform. Each first positioning plate is provided with a first positioning hole. One of the first positioning holes is used to cooperate with the mounting hole on the fishplate, and the other first positioning hole is used to cooperate with the mounting hole on the main limb. The first positioning plate is provided with a positioning member for fixing the fishplate / main limb.

[0009] By adopting the above technical solution, the main limb is placed on the first positioning plate. One of the first positioning holes (the right first positioning hole) coincides with the axis of the mounting hole on the fishplate, and the other first positioning hole (the left first positioning hole) coincides with the axis of the mounting hole on the angle steel main limb. Then, the positioning member is used to fix the main limb angle steel and the first positioning plate, achieving the purpose of fixing the position of the main limb, achieving the positioning purpose, and preventing movement during the welding process.

[0010] Further, the positioning member includes an expansion sleeve. When the axes of the first positioning hole and the mounting hole coincide, the expansion sleeve is sequentially inserted into the mounting hole and the first positioning hole. The positioning member further includes a first positioning shaft. The first positioning shaft is conical and is used to be inserted into the expansion sleeve to position the fishplate.

[0011] By adopting the above technical solution, when the axes of the first positioning hole and the mounting hole coincide, the operator sequentially inserts the expansion sleeve into the mounting hole and the first positioning hole, and then inserts the first positioning shaft into the expansion sleeve. Since the first positioning shaft is conical, as the first positioning shaft is continuously inserted into the expansion sleeve, it will be laborious to insert the upper end of the first positioning shaft into the expansion sleeve. The operator can use a knocking tool, such as a hammer, to knock the first positioning shaft into the expansion sleeve, and the diameter of the expansion sleeve will increase accordingly, achieving the purpose of fixing the fishplate through the tightening force.

[0012] Further, a guiding block is provided at the end of the first positioning shaft.

[0013] By adopting the above technical solution, the guiding block plays a guiding role, and the diameters of both ends of the first positioning shaft are a little thinner. The purpose is to use a hammer head for installation. After the end is deformed by hitting, the diameter will increase, and it is also convenient to take out.

[0014] Further, the second positioning portion includes a second positioning plate disposed on the welding platform. A second positioning hole is provided on the second positioning plate for cooperating with the connection hole on the connecting plate. The second positioning portion further includes a second positioning shaft. When the axes of the connection hole and the second positioning hole coincide, the second positioning shaft is sequentially inserted into the connection hole and the second positioning hole.

[0015] By adopting the above technical solution, when the axes of the connection hole and the second positioning hole coincide, inserting the second positioning shaft into the connection hole and the second positioning hole can achieve the purpose of positioning the connecting plate.

[0016] Further, the third positioning portion includes a third positioning plate disposed on the welding platform, and an arc-shaped block for supporting the diagonal web member is disposed on the third positioning plate.

[0017] By adopting the above technical solution, the diagonal web member is supported by the arc-shaped block, achieving the purpose of positioning the position of the diagonal web member.

[0018] Further, both the first positioning portion and the second positioning portion include a pressing block and a pressing bolt. The pressing block is used to press the fishplate / connecting plate, and the pressing bolt is used to adjust the height of the pressing block.

[0019] By adopting the above technical solution, through the cooperation of the pressing block and the pressing bolt, fishplates or connecting plates with different thicknesses can be adapted. At the same time, by adjusting the pressing force of the pressing block by adjusting the pressing bolt, the purpose of further fixing the position of the fishplate or connecting plate can be achieved.

[0020] Further, a driven gear is provided on one side of the welding platform. The driven gear meshes with a driving gear, and a driving mechanism for driving the driving gear to rotate is provided on one side of the welding platform.

[0021] By adopting the above technical solution, during the welding process of a piece of standard section links, the operator can drive the driving gear to rotate by starting the driving mechanism. The rotation of the driving gear drives the driven gear to rotate, and then drives the entire welding platform to rotate, achieving welding at different positions.

[0022] In summary, compared with the prior art, the beneficial effects of the above technical solution are:

[0023] (1) The main limb is positioned by the first positioning portion, the connecting plate is positioned by the second positioning portion, and the diagonal web member is positioned by the third positioning portion, achieving the purpose of positioning each structure of the sheet-type standard section. Then, each structure is welded in sequence to achieve the purpose of welding the entire sheet-type standard section. This solution does not require repeated positioning. After all the parts are positioned, the whole (sheet) is welded, which is simple and convenient;

[0024] (2) The main limb is placed on the first positioning plate, the axis of the first positioning hole coincides with the axis of the mounting hole on the fishplate. Then, the fishplate and the first positioning plate are fixed by using the positioning member, achieving the purpose of fixing the position of the main limb, achieving the positioning purpose, and preventing movement during the welding process;

[0025] (3) When the axes of the first positioning hole and the mounting hole coincide, the operator inserts the expansion sleeve into the mounting hole and the first positioning hole in sequence, and then inserts the first positioning shaft into the expansion sleeve. Since the first positioning shaft is conical, as the first positioning shaft is continuously inserted into the expansion sleeve, it will be laborious to insert the upper end of the first positioning shaft into the expansion sleeve. The operator can use a knocking tool, such as a hammer, to knock the first positioning shaft into the expansion sleeve, and the diameter of the expansion sleeve will increase accordingly, achieving the purpose of fixing the fishplate through the tightening force.

[0037] The principles and features of the present utility model will be described below in conjunction with all the attached drawings. The examples cited are only used to explain the present utility model and are not intended to limit the scope of the present utility model.

[0038] An embodiment of the present utility model discloses a sheet-type standard section forming and welding tooling.

[0039] Refer to Figures 1-9 , a sheet-type standard section forming and welding tooling, including a welding platform 1. A support frame 2 is provided at the bottom end of the welding platform 1. The support frame 2 is used to support the welding platform 1, and the welding platform 1 is rotationally connected to the support frame 2. The rotation axis of the welding platform 1 is horizontally arranged. A driving mechanism is provided on the support frame 2. In this embodiment, the driving mechanism is a motor 3, which can also be other structures. The output shaft of the motor 3 is fixedly connected with a driving gear 4. The driving gear 4 meshes with a driven gear 5. The driven gear 5 is fixedly connected with the welding platform 1. When the sheet-type standard section is placed and fixed on the welding platform 1, during the welding process, the operator starts the motor 3 according to different welding angles. The rotation of the output shaft of the motor 3 can drive the driving gear 4 to rotate. The rotation of the driving gear 4 drives the driven gear 5 to rotate. The rotation of the driven gear 5 drives the entire welding platform 1 to rotate, so as to realize the adjustment of the angle of the sheet-type standard section and facilitate the welding purpose.

[0040] A first positioning portion, a second positioning portion, and a third positioning portion are provided on the welding platform 1; the first positioning portion is used to position the main limb 101, the second positioning portion is used to position the connecting plate 106, and the third positioning portion is used to position the diagonal web member 105. By positioning the main limb 101 with the first positioning portion, positioning the connecting plate 106 with the second positioning portion, and positioning the diagonal web member 105 with the third positioning portion, the purpose of positioning each structure of the sheet-type standard section 100 is realized. Then, each structure is welded in sequence to realize the welding purpose of the entire sheet-type standard section 100. This solution does not require repeated positioning. After all the parts are positioned, they (the whole sheet) are welded, which is simple and convenient.

[0041] The first positioning portion includes first positioning plates 6 disposed on the welding platform 1. There are two first positioning plates 6, which are respectively located at both ends of the welding platform 1. Each first positioning plate 6 is provided with a first positioning hole 7. The axis of the first positioning hole 7 is vertically arranged. The right first positioning hole 7 is used to cooperate with the mounting hole 103 on the fishplate 102. The first positioning plate 6 is provided with a positioning member for fixing the fishplate 102. The left first positioning hole 7 is used to cooperate with the mounting hole on the main limb 101. Place the main limb 101 on the first positioning plate 6. The axes of the first positioning hole 7 and the mounting hole 103 on the fishplate 102 coincide. When their axes coincide, then use the positioning member to fix the fishplate 102 and the first positioning plate 6, and use the positioning member to cooperate with the left main limb 101 and the first positioning plate 6 to achieve the purpose of fixing the position of the main limb 101, achieving the positioning purpose and preventing movement during the welding process.

[0042] Referring to Figures 4-6 , further, the positioning member includes an expansion sleeve 12. One end of the expansion sleeve 12 is provided with a limiting convex edge. The diameter of the limiting convex edge is larger than the diameter of the first positioning hole 7. When the expansion sleeve 12 is inserted into the first positioning hole 7 and the mounting hole 103, the limiting convex edge abuts against the mounting hole 103 to limit the position of the expansion sleeve 12. The expansion sleeve 12 is also called an expansion bush or a shrink fit bushing, which will not be elaborated here. When the axes of the first positioning hole 7 and the mounting hole 103 coincide, the expansion sleeve 12 is sequentially inserted into the mounting hole 103 and the first positioning hole 7. The positioning member further includes a first positioning shaft 13. The first positioning shaft 13 is conical and is used to be inserted into the expansion sleeve 12 to position the fishplate 102. When the axes of the first positioning hole 7 and the mounting hole 103 coincide, the operator sequentially inserts the expansion sleeve 12 into the mounting hole 103 and the first positioning hole 7, and then inserts the first positioning shaft 13 into the expansion sleeve 12. Since the first positioning shaft 13 is conical, first insert the end with a smaller diameter of the first positioning shaft 13 into the expansion sleeve 12. As the first positioning shaft 13 is continuously inserted into the expansion sleeve 12, it will be more difficult to insert the upper end (the end with a gradually increasing diameter) of the first positioning shaft 13 into the expansion sleeve 12. The operator can use a knocking tool, such as a hammer, to knock the first positioning shaft 13 into the expansion sleeve 12, and achieve the purpose of fixing the fishplate 102 through the radial expansion of the expansion sleeve 12.

[0043] Further, the end of the first positioning shaft 13 is provided with a guiding block 14. The diameter of the guiding block 14 is smaller than the minimum diameter of the first positioning shaft 13. When inserting the first positioning shaft 13 into the expansion sleeve 12, the guiding block 14 plays a guiding role, as Figure 5 shown.

[0044] The second positioning part includes a second positioning plate 8 disposed on the welding platform 1, and a second positioning hole 9 is formed on the second positioning plate 8. There are two second positioning holes 9, which are used to cooperate with the two connecting holes 104 on the connecting plate 106. The second positioning part also includes a second positioning shaft. When the connecting hole 104 coincides with the axis of the second positioning hole 9, the second positioning shaft is sequentially inserted into the connecting hole 104 and the second positioning hole 9. When the axis of the connecting hole 104 and the second positioning hole 9 coincide, the second positioning shaft is inserted into the connecting hole 104 and the second positioning hole 9, so as to achieve the purpose of positioning the connecting plate 106.

[0045] The first positioning part and the second positioning part both include a clamping block 15 and a clamping bolt 16. The clamping bolt 16 penetrates the clamping block 15. The clamping block 15 is used to clamp the fish plate 102 / connecting plate 106, and the clamping bolt 16 is used to adjust the height of the clamping block 15. Taking the second positioning part as an example, two clamping blocks 15 and two clamping bolts 16 are provided, which are respectively located on both sides of the second positioning plate 8. Figure 8 and Figure 9 As shown, the clamping block 15 is located beside the second positioning plate 8. When the connecting plate 106 needs to be clamped and positioned, the clamping block 15 is clamped on the connecting plate 106. The operator turns the nut 17 on the clamping bolt 16, and the nut 17 abuts against the clamping block 15, thereby fixing the position of the clamping block 15.

[0046] Through the cooperation of the clamping block 15 and the clamping bolt 16, fish plates 102 or connecting plates 106 of different thicknesses can be adapted. At the same time, by adjusting the clamping bolt 16 to adjust the clamping force of the clamping block 15, the position of the fish plate 102 or connecting plate 106 can be further fixed.

[0047] The third positioning part includes a third positioning plate 10 disposed on the welding platform 1, and the third positioning plate 10 is disposed between the first positioning plate 6 and the second positioning plate 8. The third positioning plate 10 is provided with an arc block 11 for supporting the diagonal web member 105. Before welding, the diagonal web member 105 is placed on the arc block 11, and the diagonal web member 105 is supported by the arc block 11, so as to achieve the purpose of positioning the position of the diagonal web member 105.

[0048] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
