Technical Field

[0001] The utility model relates to the technical field of welding auxiliary equipment, in particular to an auxiliary device for truss welding. Background Art

[0002] Truss structures are widely used in architecture, bridges, stage construction, and other fields due to their high strength, light weight, and large span. Welding is a critical step in the truss manufacturing process, and its quality directly affects the overall performance and safety of the truss.

[0003] However, at present, truss welding mainly faces the following challenges:

[0004] 1. Insufficient positioning accuracy: During the welding process, accurate positioning of the workpiece is crucial. Traditional methods often rely on manual positioning, which is prone to errors and affects welding quality;

[0005] 2. Safety issues: Some traditional fixing methods may have the risk of workpiece falling off, threatening the safety of operators.

[0006] Although there are some improvement solutions in the existing technology, such as the use of pneumatic clamps and hydraulic supports, these solutions often have disadvantages such as high cost, complex maintenance, and poor portability, making them difficult to be widely promoted in actual production.

[0007] Therefore, there is an urgent need for a truss welding auxiliary device with simple structure, convenient operation, precise positioning, firm fixation and strong applicability to improve the efficiency and quality of truss welding and meet the needs of modern industrial production. Summary of the Invention

[0008] In order to solve the above problems, the utility model discloses an auxiliary device for truss welding.

[0009] In order to achieve the above objectives, the present invention provides the following technical solutions: an auxiliary device for truss welding, comprising:

[0010] leaning board;

[0011] First switch type magnetic seat;

[0012] Second switch type magnetic base;

[0013] A stopper, arranged at one side edge of the support plate;

[0014] Wherein, the stopper is used to abut against the edge of the workpiece to be welded so as to position the workpiece to be welded;

[0015] The first switch-type magnetic seat is arranged at the rear side of the support plate, and is used to absorb the workpiece to be welded located at the front side of the support plate;

[0016] The second switch-type magnetic seat is arranged at the bottom end of the backing plate and is perpendicular to the backing plate, and is used for being adsorbed and fixed on the beam surface of the truss.

[0017] In addition, in order to improve the firmness of fixing the workpiece to be welded, the auxiliary device further includes a quick clamp, which is installed on the front side of the back plate and is used to further clamp and fix the workpiece to be welded.

[0018] In order to further improve the positioning accuracy, the auxiliary device also includes a positioning block, which is arranged on the lower side of the stop block and is parallel to the second switch-type magnetic seat, and is used for aligning with the side of the truss.

[0019] Wherein, two protrusions are provided on the inner side of the positioning block, and the protrusions are used to abut against the side of the truss during operation to further position the auxiliary device.

[0020] In a possible implementation manner, the protrusion is a sphere.

[0022] The auxiliary device also includes a handle, which is arranged at the upper end of the support plate to facilitate operators to carry and position the auxiliary device.

[0023] The solution in the embodiment of the present application, by providing a stopper to abut against the edge of the workpiece to be welded, can accurately position the workpiece, avoiding errors caused by manual positioning, thereby improving welding quality.

[0031] In order to make the purpose, technical solutions and advantages of the present invention more clear, the present invention will be described in further detail below with reference to the accompanying drawings.

[0032] The terms used in the following embodiments are only for the purpose of describing specific embodiments and are not intended to limit the present invention. As used in the specification of the present invention and the appended claims, the singular expressions "a", "an", "above", "the", and "this" are intended to also include expressions such as "one or more", unless the context clearly indicates otherwise.

[0033] References to "one embodiment" or "some embodiments" in this specification mean that a particular feature, structure, or characteristic described in conjunction with that embodiment is included in one or more embodiments of the present invention. Thus, phrases such as "in one embodiment," "in some embodiments," "in other embodiments," and "in yet other embodiments" appearing in various places in this specification do not necessarily refer to the same embodiment, but rather mean "one or more, but not all, embodiments," unless otherwise specifically emphasized. The terms "including," "comprising," "having," and variations thereof mean "including but not limited to," unless otherwise specifically emphasized.

[0034] Example 1: See Figure 1-5 As shown, an auxiliary device for truss welding includes:

[0035] Back plate 100;

[0036] First switch type magnetic base 101;

[0037] Second switchable magnetic base 102;

[0038] A stopper 103 is provided at one side edge of the support plate 100;

[0039] The stopper 103 is used to abut against the edge of the workpiece to be welded so as to position the workpiece to be welded;

[0040] The first switch-type magnetic seat 101 is provided at the rear side of the support plate 100 and is used to absorb the workpiece to be welded located at the front side of the support plate 100;

[0041] The second switch-type magnetic seat 102 is disposed at the bottom end of the backing plate 100 and is perpendicular to the backing plate 100 , and is used for being adsorbed and fixed on the beam surface of the truss.

[0042] In a specific embodiment, the support plate 100 serves as the main structure of the entire auxiliary device and provides a mounting base for other components. The support plate 100 can be made of non-magnetic materials, such as aluminum alloy or engineering plastics, to avoid interference with the magnetic base.

[0043] The stopper 103 is provided at one side edge of the support plate 100 and is used to abut against the edge of the workpiece to be welded, thereby preliminarily positioning the workpiece to be welded. The stopper 103 can be made of wear-resistant material to extend its service life.

[0044] The first switchable magnetic base 101 is provided at the rear side of the support plate 100 and is used to attract the workpiece to be welded located in front of the support plate 100. The magnetic force of the first switchable magnetic base 101 can be controlled by a switch, facilitating the installation and removal of the workpiece.

[0045] A second switchable magnetic base 102 is positioned at the bottom of the support plate 100, perpendicular to the support plate 100. This second switchable magnetic base 102 is designed to be attached to the beam surface of the truss, thereby securing the entire auxiliary device to the truss structure. Similarly, this second switchable magnetic base 102 also features a magnetic switch, facilitating installation and removal of the device.

[0046] like Figure 1 As shown, during use, the operator first attaches the second switchable magnetic base 102 to the beam surface of the truss 109. Then, the workpiece 108 to be welded is placed in front of the support plate 100, with its edge resting against the stop 103. Next, the first switchable magnetic base 101 is activated to securely attach the workpiece 108 to the weld. This allows the welder to precisely position and secure the workpiece 108, allowing them to begin welding. After welding is complete, the magnetic base is turned off, allowing the workpiece and auxiliary device to be easily removed.

[0047] In addition, the surface of the backing plate 100 is provided with anti-slip protrusions to increase the friction between the backing plate 100 and the workpiece to be welded. The protrusions can be evenly arranged circular granular protrusions.

[0048] The auxiliary device further includes a handle 107 , which is disposed at the upper end of the support plate 100 to facilitate an operator in carrying and positioning the auxiliary device.

[0049] In this embodiment, the switchable magnetic base operates by altering the magnetic circuit of a permanent magnet to control magnetic force. When the switch is in the "on" position, magnetic lines of force pass through the working surface, forming a strong magnetic field. When the switch is in the "off" position, the magnetic lines of force form a closed loop within the base, leaving the working surface virtually free of magnetic force.

[0050] Common switch-type magnetic base types include:

[0051] Manual rotary switch type: the magnetic switch is controlled by rotating the handle;

[0052] Manual flip switch type: A switch that controls the magnetic force by flipping the operating lever.

[0053] You can choose a suitable switch-type magnetic base model based on your actual needs. For example, for the first switch-type magnetic base 101, you can choose a medium-suction model such as Eclipse Magnetics E934 or Magswitch8100351. These models have sufficient suction force to fix workpieces of average size to be welded and are easy to operate.

[0054] For the second switch-type magnetic base 102 , considering that it needs to bear the weight of the entire auxiliary device, a high-suction model such as Walmag NEOSNAP 2000 or Walker BNE3050 can be selected to ensure that the auxiliary device can be firmly adsorbed on the truss beam surface.

[0055] Example 2: See Figure 1-4 As shown, in order to further improve the firmness of the workpiece to be welded, the auxiliary device of the present invention also includes a quick clamp 104. Figure 3 As shown, a quick clamp 104 is installed on the front side of the backing plate 100 for further clamping and fixing the workpiece to be welded.

[0056] The quick clamp 104 can be in various forms, such as an adjustable lever clamp, a screw clamp or a pneumatic clamp, etc. In this embodiment, a lever-type quick clamp is preferably used, which is easy to operate and can quickly clamp and release the workpiece, greatly improving work efficiency.

[0057] The quick clamp 104 is used as follows: First, place the workpiece to be welded on the backing plate 100 so that it abuts against the stopper 103. Then, operate the quick clamp 104 so that its chuck contacts the workpiece and applies appropriate pressure. Finally, lock the clamp. This secures the workpiece to be welded to the backing plate 100.

[0058] By adding the quick clamp 104, the auxiliary device of the present invention achieves multiple fixations of the workpiece to be welded. The combined effects of magnetic attraction, friction, and mechanical clamping ensure the stability of the workpiece during welding, thereby improving welding quality and accuracy.

[0059] Example 3: See Figure 1-5 As shown, in order to further improve the positioning accuracy, the auxiliary device also includes a positioning block 105, which is arranged on the lower side of the stop block 103 and is parallel to the second switch type magnetic seat 102, for aligning with the side of the truss.

[0060] The purpose of the positioning block 105 is to provide an additional positioning reference to ensure that the auxiliary device is installed on the truss more accurately. When the auxiliary device is installed on the truss, the positioning block 105 will contact the side of the truss, thereby limiting the horizontal movement of the auxiliary device.

[0061] Furthermore, two protrusions 106 are located inside the positioning block 105. These two protrusions 106 rest against the sides of the truss during operation, allowing for more precise positioning of the auxiliary device. The presence of protrusions 106 reduces the contact area with the truss, minimizing positioning errors caused by surface unevenness, thereby achieving more precise positioning.

[0062] In a preferred embodiment of the present invention, the bump 106 is in the shape of a sphere. When the sphere contacts the plane, there is only one point, and the position of this point is relatively fixed, which is conducive to improving positioning accuracy.

[0063] During use, the operator first attaches the auxiliary device's second switch-type magnetic base 102 to the truss beam surface, then adjusts the position so that the two spherical protrusions 106 of the positioning block 105 are in close contact with the side of the truss. In this way, the auxiliary device is accurately fixed in the predetermined position.

[0064] By introducing the positioning block 105 and the spherical bump 106 , the auxiliary device of the present invention achieves higher precision positioning, further improving welding quality and efficiency.

[0065] The technical means disclosed in the present invention are not limited to those disclosed in the above-mentioned embodiments, but also include technical solutions composed of any combination of the above-mentioned technical features. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of the present invention, and such improvements and modifications are also considered to be within the scope of protection of the present invention.
