[0034] Hereinafter, specific embodiments of the present application will be described with reference to the accompanying drawings; however, it should be understood that the embodiments claimed are only examples of the present application, which can be implemented in various ways. Well - known and / or repetitive functions and structures are not described in detail to clarify the true intention based on the user's historical operations and to avoid obscuring the present application with unnecessary or redundant details. Therefore, the specific structural and functional details claimed herein are not intended to be limiting, but are only used as a basis for the claims and a representative basis for teaching those skilled in the art to use the present application in substantially any suitable detailed structure in a variety of ways.

[0035] This specification may use the phrases "in one embodiment", "in another embodiment", "in yet another embodiment" or "in other embodiments", each of which may refer to one or more of the same or different embodiments according to the present application.

[0036] The principles and features of the present invention will be described below in conjunction with the accompanying drawings. The embodiments cited are only used to explain the present invention and are not intended to limit the scope of the present invention. The following in conjunction with Figures 1-7 ... will be further described in detail with respect to the preferred embodiments of the present invention:

[0037] As Figure 3 shown, an embodiment of the present invention provides a welding fixture for a bone beam and an ear plate, comprising:

[0038] A main frame 1, the main frame 1 being a concave - shaped frame structure, including a support base 101 and a first support arm 102 and a second support arm 103 respectively fixed at both ends of the support base 101, and a receiving space for accommodating the bone beam 5 is formed among the support base 101, the first support arm 102 and the second support arm 103;

[0039] A beam pressing member 2 is provided on the first support arm 102. It can press and fix the bone beam 5 placed in the accommodation space against the inner support vertical surface 104 of the second support arm 103.

[0040] A plate pressing member 3 is provided on the second support arm 103. It can press and vertically fix the ear plate 6 placed at the top support top surface 105 of the second support arm 103 against the flange of the bone beam 5.

[0041] The bone beam 5 is placed in the accommodation space surrounded by the support base 101, the first support arm 102 and the second support arm 103. The beam pressing member 2 cooperates with the second support arm 103 to clamp the bone beam 5 and fix the bone beam 5. The ear plate 6 is placed on the top support top surface 105 of the second support arm 103. The plate pressing member 3 cooperates with the bone beam 5 to clamp the ear plate 6 and fix the ear plate 6.

[0042] Considering that the position of the bone beam 5 is not stable when it is fixed only by the static friction force added by the clamping force. It may cause the bone beam 5 to be displaced due to the disturbance generated by the operator when clamping the ear plate 6 or welding, resulting in the ear plate 6 deviating from the original welding position, or the problem that the bone beam 5 and the ear plate 6 are not welded at a 90° angle. To avoid the above problems, in an embodiment, the endpoints at the top of the support base 101 are all located in a plane, and the bottom end of the bone beam 5 abuts against the top surface of the support base 101. Placing the bone beam 5 directly on the top surface of the support base 101 can avoid the vertical displacement of the bone beam 5 under the action of gravity. At this time, only the pressing force provided by the beam pressing member 2 can ensure that the position stability of the bone beam 5 meets the construction requirements.

[0043] As described above, although placing the bone beam 5 directly on the top surface of the support base 101 can overcome the problem of insufficient position stability of the bone beam 5 and improve the welding accuracy of the bone beam 5 and the ear plate 6, this implementation method also makes the entire tooling only meet the welding requirements of a part of the models of the bone beam 5. That is, only when the bone beam 5 is placed in place and the ear plate 6 placed at the top support top surface 105 of the second support arm 103 can exactly be located at the scribed position to be welded on the bone beam 5, the entire tooling can be put into use. This limits the versatility of the tooling to a certain extent. For this problem, as Figures 1-2As shown, in one embodiment, a support bracket 4 is further provided on the main body frame 1. The support bracket 4 can adjust its relative position with the first support arm 102 along the length direction of the first support arm 102, and can remain fixed relative to the main body frame 1 after the position adjustment is in place. Each end point at the top of the support bracket 4 is located in a plane, and the bottom end of the stiffening beam 5 abuts against the top surface of the support bracket 4. By providing a movable support bracket 4 below the stiffening beam 5, when the model of the stiffening beam 5 changes, the position of the support bracket 4 can be correspondingly moved so that the support bracket 4 supports the stiffening beam 5 to improve its position stability. In this way, while improving the welding accuracy between the stiffening beam 5 and the ear plate 6, the tooling can meet the welding requirements of various models of the stiffening beam 5;

[0044] The specific design form of the support bracket 4 can be reasonably selected according to the on-site use requirements. For example, a support plate (or support rod) is added between the first support arm 102 and the second support arm 103 of the main body frame 1, and then a telescopic jacking member (such as an electric, manual or hydraulic telescopic rod, etc.) is provided between the support plate (or support rod) and the support base 101, as Figures 6-7 As shown, in one embodiment, in order to reduce the manufacturing cost and operation difficulty, the support bracket 4 includes a support frame 402 and a support bolt 401. The support frame 402 is sleeved on the main body frame 1, and its size matches the outer envelope size of the first support arm 102 and the second support arm 103, and the support frame 402 can slide along the first support arm 102 and the second support arm 103. Long strip-shaped second through holes 107 extending along the length directions of the first support arm 102 and the second support arm 103 are correspondingly opened on the first support arm 102 and the second support arm 103. The support bolt 401 is correspondingly inserted into the second through hole 107, and it can be fixed at a certain position in the second through hole 107 in a way of tensioning and fixing, and the bottom end of the support frame 402 abuts against the support bolt 401. Of course, in order to further improve the stability of the support bolt 401, tooth grooves can be opened on the plate surface near the second through hole 107, and then a tooth pad is correspondingly sleeved on the support bolt 401 to prevent the problem of sliding after the support bolt 401 is tensioned and fixed. Of course, in order to avoid the problem of position conflict between the support frame 402 and the beam pressing member 2 or the plate pressing member 3 when the support frame 402 moves up to adjust the position, the support frame 402 is provided with a relief groove 403 corresponding to the positions of the beam pressing member 2 and the plate pressing member 3;

[0045] As described in the background art section, the bone beam 5 needs to be welded and fixed to the ear plate 6 at an angle of 90°. If the angle needs to be adjusted manually during the welding of each ear plate 6, it will inevitably lead to a decrease in the welding and assembly efficiency. Therefore, in one embodiment, all endpoints on the support vertical surface 104 are located in one plane, all endpoints on the support top surface 105 are located in another plane, and the planes where the endpoints of the support vertical surface 104 are located and the planes where the endpoints of the support top surface 105 are located are perpendicular to each other. By directly setting the abutting surface of the bone beam 5 and the placement surface of the ear plate 6 to be perpendicular to each other, after the bone beam 5 is fixed to the support vertical surface 104 by the beam pressing member 2, both the support vertical surface 104 and the outer facade of the flange of the bone beam 5 are vertical surfaces. At this time, the support top surface 105 is a horizontal plane. When the ear plate 6 is placed on the support top surface 105, the ear plate 6 will naturally fit with the bone beam 5 at an angle of 90°. At this time, the ear plate 6 and the bone beam 5 can be pressed by the plate pressing member 3 for welding, that is, only need to place and clamp the ear plate 6, without complex angle adjustment operations;

[0046] Among them, as Figure 5 shown, in one embodiment, the beam pressing member 2 includes a first screw 201, the first screw 201 is passed through a first through hole 106 opened on the first support arm 102 and is in threaded cooperation with the first support arm 102;

[0047] a pressing block 204, the pressing block 204 is arranged at one end of the first screw 201 close to the bone beam 5;

[0048] On this basis, in order to facilitate turning the first screw 201 for depth adjustment, in one embodiment, the beam pressing member 2 further includes a handle 202, the handle 202 is fixedly arranged at one end of the first screw 201 far from the bone beam 5;

[0049] At the same time, in order to prevent the pressing block 204 from rotating when turning the first screw 201 and causing scratches on the surface of the bone beam 5, the pressing block 204 is pivotally connected to the first screw 201 in a rotatable manner. For example, the first screw 201 and the pressing block 204 are rotatably connected in the form of a bearing or a ball hinge joint;

[0050] Since it is difficult to directly open the first through hole 106 in the form of a threaded hole on the first support arm 102, and due to the wall thickness problem, the contact area between the hole wall of the first through hole 106 and the first screw 201 is limited, and the first screw 201 is prone to jamming problems when rotating. Therefore, a sleeve 203 can be directly sleeved on the first screw 201, and then the sleeve 203 is passed through the first through hole 106 and welded and fixed to the peripheral hole wall of the first through hole 106;

[0051] As Figure 4As shown, in one embodiment, the main frame 1 is made by cutting off the flanges at some positions of square steel with a hollow structure, or is formed by enclosing and welding steel plates, so as to ensure that the main frame 1 has sufficient structural strength while minimizing its own weight, facilitating the movement of the main frame 1 on the workbench;

[0052] In one embodiment, the plate pressing member 3 includes a second screw 301, and one end of the second screw 301 is fixed on the second support arm 103;

[0053] A pressing plate 302, the pressing plate 302 is sleeved on the second screw 301 and is in threaded cooperation with the second screw 301. By rotating the pressing plate 302, its position on the second screw 301 can be adjusted, and then the ear plate 6 can be tightly pressed on the flange of the stiffener beam 5, cooperating with the stiffener beam 5 to fix the ear plate 6.

[0054] During use, first prepare the corresponding number of toolings according to the number of ear plates 6 to be welded on the stiffener beam 5. Then, place each main frame 1 on the working surface of the workbench, and adjust the position of the main frame 1 according to the relative position of the ear plate 6 on the stiffener beam 5. After that, adjust the height of the support bracket 4 so that the scribed position of the web height of the stiffener beam 5 (taking the I-beam as an example) is basically aligned with the top support surface 105 of the second support arm 103. At this time, it should be noted to leave the thickness of the ear plate 6 to ensure that the ear plate 6 can be aligned with the scribed position after being placed. (Of course, the thickness of the ear plate 6 can also be considered during the scribing stage, and the scribed position can be moved down to the elevation position of the support surface 105. At this time, when fixing the stiffener beam 5, the scribed position can be directly aligned.) Since at least one ear plate 6 is provided at the end of each stiffener beam 5, there will be no problem of eccentricity and instability after the stiffener beam 6 is placed in place. After the stiffener beam 5 is placed in place, adjust the beam pressing member 2 to make the stiffener beam 5 abut against the support vertical surface 104 and fix it. Then, place the ear plate 6 at the support top surface 105 and adjust the plate pressing member 3 in place to fix the ear plate 6. Next, the welding process of the ear plate 6 and the stiffener beam 5 can be carried out. During welding, spot welding can be used for fixation first, and then full welding can be carried out along the joint. After one side of the welding is completed, loosen the beam pressing member 2 and the plate pressing member 3, remove the stiffener beam 5, turn it over and then fix it again, and also fix the other side weld of the stiffener beam 5 and the ear plate 6 by full fillet welding. After one stiffener beam 5 is welded, carry out the welding operation on the subsequent stiffener beams 5 in the same way until all the stiffener beams 5 are welded.

[0055] The present invention solves the problem that the traditional welding process requires continuous scribing and angle correction before welding, greatly improves the assembly efficiency and ensures the assembly accuracy, and has low manufacturing cost, can be reused and is applicable to the assembly of I-beam ear plates of different sizes. At the same time, only one person is required to operate the whole process, effectively saving labor costs.

[0056] The above embodiments are only exemplary embodiments of the present invention and are not used to limit the present invention. The protection scope of the present invention is defined by the claims. Those skilled in the art can make various modifications or equivalent substitutions within the essence and protection scope of the present invention, and such modifications or equivalent substitutions should also be regarded as falling within the protection scope of the present invention.
