Description

Technical Field

[0001] This utility model relates to the field of auxiliary tools for material welding, and in particular to a device for preventing deformation of fillet welds on a support plate. Background Technology

[0002] In fields such as construction engineering and metal support manufacturing, metal supports are used either as general-purpose tools, as building facilities, or as custom-made production parts. Metal supports are generally welded together from several metal pipes, with at least two pipes required to be connected at corners via fillet welds. These pipes can be square or round. If the pipe is square, an inclined cut must be formed at its welding end, which is then joined to another square pipe with a similar inclined cut via fillet weld. If the pipe is round, a beveled cut is also required at its welding end for welding. This beveled cut allows for the design of the metal support's erection angle and ensures a strong weld. The specific inclination of the beveled cut varies depending on the specific design requirements of the metal support. During and after the welding of metal materials, due to the thermal stress generated by the high temperature of welding and the cooling deformation during cooling, if the welding position is turned over and adjusted during the welding process, or if the welded parts are not placed properly after welding, resulting in uneven stress around the weld, the welded structure will be directly deformed at the weld. In particular, the fillet weld is more susceptible to the above factors and the consequences are more obvious, thus affecting the welding quality and its smooth use in the later stage, and even affecting the quality and stress of the support. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a flexible support plate fillet weld anti-deformation device that does not require material adjustment during the welding process, ensures uniform material stress throughout the entire welding operation and the static cooling process after completion.

[0004] To solve the above-mentioned technical problems, the technical solution of this utility model is: a bracket plate fillet weld anti-deformation device, including a fillet weld support platform. A fillet weld positioning component for limiting the bracket assembly is detachably installed at the top center of the fillet weld support platform. A lifting pad is also fixedly installed at the top of the fillet weld support platform. The lifting pad surrounds the outer periphery of the fillet weld positioning component, and the top surface of the lifting pad is not lower than the highest point of the fillet weld positioning component. Fillet weld fixing devices for fixing the bracket assembly are arranged on the lifting pad and cooperate with each other. The fillet weld fixing devices are arranged around the fillet weld positioning component. Each fillet weld fixing device passes through the lifting pad and is detachably assembled with the fillet weld support platform.

[0005] As a preferred technical solution, the fillet weld positioning component includes a fillet weld positioning plate, on which positioning bolts are arranged. The top of the positioning bolts is set lower than the top surface of the lifting pad, and each positioning bolt passes through the fillet weld positioning plate and is threadedly engaged with the fillet weld support platform.

[0006] As a preferred technical solution, a fillet weld positioning hole is provided through the fillet weld positioning component and the fillet weld support platform for the bracket assembly to pass through and be placed.

[0007] As a preferred technical solution, the fillet weld support platform includes a support platform plate, and a support base is provided at the bottom end of the support platform plate.

[0008] As a preferred technical solution, a connecting auxiliary platform is fixedly installed on the support base frame below the support platform. An auxiliary positioning component is provided on the auxiliary platform directly below the fillet weld positioning component. The auxiliary positioning component is used to cooperate with the lower limit of the bracket assembly.

[0009] As a preferred technical solution, the fillet weld positioning hole is set as a square hole, and four fillet weld fixing devices are arranged.

[0010] As a preferred technical solution, the fillet weld positioning hole is set as a round hole, and at least three fillet weld fixing devices are arranged.

The fixing locking bolt passes through the lifting pad and is threadedly engaged with the fillet weld support platform.

[0012] As an improvement to the above technical solution, the contact end between the fillet weld fixing plate and the bracket assembly is provided with a mating avoidance slope, and the mating avoidance slope is arranged opposite to the fillet weld fixing plate.

[0013] Due to the adoption of the above technical solution, the anti-deformation device for the fillet weld of the support plate includes a fillet weld support platform. A fillet weld positioning component for limiting the position of the support assembly is detachably installed at the top center of the support platform. A lifting pad is also fixedly installed at the top of the support platform. The lifting pad surrounds the fillet weld positioning component, and its top surface is not lower than the highest point of the positioning component. Fillet weld fixing devices for fixing the support assembly are arranged on the lifting pad, and these devices surround the positioning component. Each fixing device penetrates the lifting pad. The bracket can be detachably assembled with the fillet weld support platform. This utility model has the following advantages: one of the two bracket components that need to be fillet welded is horizontally fixed using a conventional fixing platform, and the other bracket component is vertically fixed and held by the fillet weld fixing device. Welding can then be carried out at the fillet weld position. There is no need to adjust the position of the bracket components during the entire welding process. After welding, it is allowed to cool naturally. Since the periphery of the weld will not come into contact with external objects, the stress is uniform, which can effectively prevent deformation and thus ensure the welding quality. Moreover, the welding operation can be carried out continuously around the joint. The welding operation is simple and efficient. Attached Figure Description

Detailed Implementation

[0015] The present invention will be further described below with reference to the accompanying drawings and embodiments. In the following detailed description, only certain exemplary embodiments of the present invention are described by way of illustration. Undoubtedly, those skilled in the art will recognize that various modifications can be made to the described embodiments without departing from the spirit and scope of the present invention. Therefore, the drawings and description are illustrative in nature and not intended to limit the scope of the claims.

[0016] like Figure 1 , Figure 2 and Figure 3 As shown, the anti-deformation device for the fillet weld of the support plate is used to manufacture the support components, which are generally square or round tubes. Depending on the specific design requirements of the support, sometimes the ends of two tubes 1 need to be beveled for fillet weld connection, so that the two tubes 1 form a certain angle after connection, thereby strengthening the support. In this embodiment, when performing a fillet weld on two tube diameters, one tube diameter is vertically fixed, and its upper end abuts against the end of another tube diameter that is horizontally fixed using a conventional fixing platform. A certain angle is formed at the abutment point. Welding tools are used to weld around the abutment ends of the two tubes 1, forming a fillet weld after welding. No position adjustment of the two tubes 1 is required during the entire welding process. After welding, they are allowed to cool naturally. Since the periphery of the weld does not contact external objects, the stress is uniform, effectively preventing deformation and ensuring welding quality. To fully utilize the cooling time after welding and improve or ensure work efficiency, at least two sets can be set up for alternating use.

[0017] This embodiment specifically includes a fillet weld support platform for supporting various accessories and for supporting and fixing the vertically erected pipe fitting 1 during welding. The fillet weld support platform generally has a support plate 2, and a support base 3 is provided at the bottom end of the support plate 2. The support base 3 is used to raise and support the support plate 2. If the lifting height of the support plate 2 using the support base 3 is insufficient to utilize the pipe diameter, the support base 3 can be raised again using a scaffolding structure.

[0018] A fillet weld positioning component is detachably installed at the top center of the fillet weld support platform to limit the positioning of the support assembly (i.e., the vertically positioned pipe 1). A lifting pad 4 is also fixedly installed at the top of the fillet weld support platform. The lifting pad 4 surrounds the fillet weld positioning component, and its top surface is not lower than the highest point of the fillet weld positioning component. Fillet weld fixing devices that cooperate with each other to fix the support assembly are arranged on the lifting pad 4, and these devices surround the fillet weld positioning component. Each fillet weld fixing device passes through the lifting pad 4 and is detachably assembled with the fillet weld support platform. The lifting pad 4 eliminates the obstruction caused by the fillet weld positioning component during operation of the fillet weld fixing devices. A rubber pad can also be laid on the surface of the lifting pad 4 to reduce operating noise and increase the friction between the fillet weld fixing devices and the lifting pad 4, thereby improving the fixing effect of the fillet weld fixing devices.

[0019] The fillet weld positioning component includes a fillet weld positioning plate 5, on which positioning bolts 6 are arranged. The top of the positioning bolts 6 is set lower than the top surface of the lifting pad 4. Each positioning bolt 6 passes through the fillet weld positioning plate 5 and is threadedly engaged with the fillet weld support platform, so that the fillet weld positioning plate 5 can be disassembled and replaced to meet the needs of vertical fixing of pipes of different sizes, making the device more flexible.

[0020] In this embodiment, a fillet weld positioning hole 7 is provided through the fillet weld positioning component and the fillet weld support platform for the bracket assembly to pass through and be placed, so that the bottom end of the pipe 1 can extend downwards towards the support platform 2 to accommodate the welding of pipes 1 of different lengths.

[0021] An auxiliary support plate 8 is fixedly installed on the support base 3 below the support platform 2. An auxiliary positioning component 9 is located directly below the fillet weld positioning component on the auxiliary support plate 8. The auxiliary positioning component 9 is used to limit the lower part of the support assembly, cooperating with the fillet weld positioning component to improve the stability of the pipe 1 when placed vertically, thus contributing to improved fillet weld quality. The structure of the auxiliary positioning component 9 corresponds to that of the fillet weld positioning component; it is also an assembly of plate, bolt, and hole, limiting the lower part of the pipe 1 and preventing it from shaking during welding. The auxiliary positioning component 9 is also an assembly of plate, bolt, and pipe seat. A positioning pipe seat is fixedly installed at the center of the plate of the auxiliary positioning component 9 for fitting with the bottom end of the pipe 1, achieving positioning support for the lower end of the pipe 1.

[0022] like Figure 3As shown, when performing fillet welding on the square tube, the fillet weld positioning hole 7 is set as a square hole, and four fillet weld fixing devices are arranged. Each fillet weld fixing device abuts against the straight edge of the square tube to achieve clamping and fixing of the tube diameter. Figure 4 As shown, when performing fillet welding on a round tube, the fillet weld positioning hole 7 is set as a round hole, and at least three fillet weld fixing devices are arranged. By rotating the fillet weld fixing device, it is made to abut against the outer wall of the round tube to achieve clamping and fixing of the round tube.

[0023] The fillet weld fixing device of this embodiment includes a fillet weld fixing plate 10 for fixing the support assembly. An adjusting elongated hole 11 is provided through the fillet weld fixing plate 10, and a fixing locking bolt 12 is fitted into the adjusting elongated hole 11. The fixing locking bolt 12 passes through the lifting pad 4 and is threadedly engaged with the fillet weld support platform. With the cooperation of the fixing locking bolt 12 and the adjusting elongated hole 11, the fillet weld fixing plate 10 can be translated and rotated to achieve the clamping and support of round or square tubes. A mating avoidance slope 13 is also provided at the contact end between the fillet weld fixing plate 10 and the support assembly. The mating avoidance slope 13 is arranged opposite to the fillet weld fixing plate 10 to reduce interference between the fillet weld fixing plates 10 during rotational adjustment, making it suitable for smaller pipe fittings 1.

Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described in order to better illustrate the principles and practical application of the utility model, and to enable those skilled in the art to understand the utility model and design various embodiments with various modifications suitable for a particular purpose.
