Description

Technical Field

[0001] This utility model relates to the welding of thin plates with inner curved surfaces in the field of welding, and more particularly to a support and fixing device for welding thin plates with inner curved surfaces. Background Technology

[0002] When welding thin plates with inner curved surfaces, the heat release during welding often causes severe shrinkage and deformation at the weld joint, resulting in dimensional deviations. Therefore, it is necessary to fix and tighten both ends of the weld joint.

[0003] However, in the process of implementing the inventive technical solution in the embodiments of this application, the inventors of this application discovered that the above-mentioned technology has at least the following technical problems:

[0004] Due to the thickness of the sheet metal, welding anchoring is not permitted within the curved surface to be welded, making it impossible to install support fixtures. Therefore, on-site fitting of support timber is necessary. This results in low fit accuracy, poor clamping effect, and frequent weld shrinkage and poor flatness after welding. Summary of the Invention

[0005] To address the shortcomings of existing technologies, particularly the low precision and poor clamping effect in the welding of curved panels, this application provides a welding support and fixing device for inner curved thin plates.

[0009] The support rod includes a fixing screw I, a fixing screw II, an adjusting screw, and a connecting hinge;

[0010] The adjusting screw is a long nut with a positive internal thread at one end and a negative internal thread at the other end, used for screwing and adjusting the length of the support rod; the fixing screw I is a threaded shaft with an internal thread at one end for connecting to the connecting hinge; the other end has a positive external thread that matches the positive internal thread of the adjusting screw, used for screwing to the positive internal thread end of the adjusting screw; the fixing screw II is also a threaded shaft with an internal thread at one end for connecting to the connecting hinge; the other end has a negative external thread that matches the negative internal thread of the adjusting screw, used for screwing to the negative internal thread end of the adjusting screw; one end of the connecting hinge is connected to the clamping seat, and the other end is connected to either fixing screw I or fixing screw II;

The outer ends of fixed screw I and fixed screw II are connected to the pressure seat through connecting hinges. The pressure seat at one end of the two adjusting screws forms two flexible support points. The other ends of the two adjusting screws are connected to the same pressure seat through connecting hinges to form a third flexible support point and linkage between the two support rods.

[0012] In order to further solve the technical problems to be solved by the embodiments of this application, the clamping seat provided by the embodiments of this application includes a U-shaped groove and a locking screw;

[0013] The U-shaped channel is a cuboid structure with a U-shaped through groove.

[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Although embodiments of the present utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0035] This application provides a welding support and fixing device for inner curved thin plates, which solves the problems of low fitting accuracy and poor clamping effect that are common in the welding of inner curved panels in the prior art. By using a structure of two linked support rods and three support points, it achieves the effect of adaptively adjusting the angle and clamping and fixing the weld of the curved panel.

[0036] As shown in the figure, a welding support and fixing device for thin plates with inner curved surfaces includes a support rod and a clamping seat 1.

[0037] The support rod is a combination rod that can be adjusted in length. One end of each of the two support rods is equipped with a clamping seat 1, and a wooden block is clamped on the clamping seat 1. The other ends meet on the same clamping seat 1, forming an adjustable structure with two support rods linked together and three support points to adapt to the welding of curved panels.

[0038] The support rod includes a fixing screw I 3, a fixing screw II 5, an adjusting screw 4, and a connecting hinge 2;

[0039] The adjusting screw 4 is a long nut with a positive internal thread at one end and a reverse internal thread at the other end. It is used for screwing and adjusting the length of the support rod to adapt to the adaptive needs of different curved panels.

[0040] In this embodiment, the adjusting screw 4 is made of φ38mm 7075 aluminum rod;

[0041] The fixed screw I3 has a threaded shaft, one end of which is provided with an internal thread for connecting to the connecting hinge 2; the other end is provided with a positive external thread that matches the positive internal thread of the adjusting screw 4 and is used to screw into the positive internal thread end of the adjusting screw 4.

[0042] The fixing screw II5 is also a threaded shaft. One end is provided with an internal thread for connecting to the connecting hinge 2; the other end is provided with a reverse external thread, which matches the reverse internal thread of the adjusting screw 4 and is used to screw into the reverse internal thread end of the adjusting screw 4.

[0043] In this embodiment, the fixing screw I3 and fixing screw II5 have the same structure, except that the external threads face opposite directions; both fixing screw I3 and fixing screw II5 are made of φ20mm 7075 aluminum rod.

[0044] One end of the connecting hinge 2 is connected to the clamping seat 1, and the other end is connected to the fixing screw I3 or the fixing screw II5, so that the support rod is rotatably connected to the clamping seat 1, thereby realizing the adaptive adjustment of the clamping state of the clamping seat 1 on the curved panel.

[0045] The adjusting screw 4 is screwed to the fixed screw I 3 and the fixed screw II 5 at both ends, and the connection and length adjustment are achieved through the thread, forming a combined rod that can adjust the length. The outer ends of the fixed screw I 3 and the fixed screw II 5 are connected to the pressure seat 1 through the connecting hinge 2. The pressure seat 1 at one end of the two adjusting screws 4 forms two flexible support points. The other ends of the two adjusting screws 4 are connected to the same pressure seat 1 through the connecting hinge 2, forming a third flexible support point and linkage between the two support rods.

[0046] The technical solutions described in the embodiments of this application above have at least the following technical effects or advantages:

[0047] Because the device uses two support rods linked together and has three flexible support points, the force of the two support rods structure makes the intersection of the two support rods a support point. At the same time, the angle between the two support rods can be adjusted adaptively, thereby pressing and fixing the weld of the curved panel, improving the fitting accuracy and welding quality of the curved panel welding, and thus improving work efficiency.

[0048] To ensure the stability of the structure in this embodiment, the clamping seat 1 includes a U-shaped groove 11 and a locking screw 12;

[0049] U-shaped groove 11 is a cuboid structure with a U-shaped through groove. Wooden squares are inlaid in the U-shaped through groove to contact curved steel plates, forming flexible support points.

[0050] Locking screws 12 are used to clamp the timber and make fine adjustments to the timber. Locking screws 12 are symmetrically arranged on both sides of the U-shaped groove 11 to clamp the timber, and locking screws 12 are arranged at the bottom of the U-shaped groove 11 to adjust the timber.

[0051] The technical solutions described in the embodiments of this application above have at least the following technical effects or advantages:

[0052] Because a U-shaped groove 11 is provided on the clamping seat 1, and a wooden block can be embedded in the U-shaped groove 11, the wooden block contacts the curved panel, and the friction between the non-metallic material and the metallic material forms a flexible support point, which can avoid scratching and damaging the surface of the curved panel when supporting it.

[0053] Since locking screws 12 are provided on both wings and at the bottom of the U-shaped groove 11, the locking screws 12 on both wings of the U-shaped groove 11 can clamp and fix the wood. At the same time, the locking screws 12 at the bottom of the U-shaped groove 11 can also be adjusted to press the wood against the contact point of the curved panel, forming a stable support, improving the welding accuracy of the curved panel, and achieving the effect of pressing the curved panel.

[0054] To further ensure the stability of the structure in this embodiment, the connecting hinge 2 includes a hanger 21, a hanger rod 22, and a bolt assembly 23;

[0055] The suspension rod 22 is a stepped shaft with an external thread at one end, which matches the internal thread of the fixing screw I3 or fixing screw II5 for screwing; the other end has a through hole for rotatable connection.

[0056] The lifting base 21 is a set of lifting lugs, which are connected to the bottom of the U-shaped groove 11 of the clamping seat 1. Specifically, it is welded to the bottom of the U-shaped groove 11 to form a support seat for assembling the lifting rod 22. Bolt holes are provided on the lifting base 21 for rotatable connection with the lifting rod 22.

[0057] Bolt assembly 23 passes through bolt holes on hanger 21 and through holes on rod 22, forming a rotatable connection between rod 22 and hanger 21.

[0058] The technical solutions described in the embodiments of this application above have at least the following technical effects or advantages:

[0059] Since the hanger 21 of the connecting hinge 2 is connected to the bottom of the clamping seat 1, and the hanger rod 22 is connected to the fixing screw I 3 or the fixing screw II 5, the hanger 21 and the hanger rod 22 are connected by the bolt assembly 23, and then the hanger 21 and the hanger rod 22 are rotatably connected, thereby the support rod is rotatably connected to the clamping seat 1, so as to realize the clamping posture of the support rod.

[0060] To optimize the structure of this embodiment, a rotary handle 6 is provided radially on the outer surface of the adjusting screw 4 for rotating the adjusting screw 4 to adjust the length of the support rod.

[0061] The technical solutions described in the embodiments of this application above have at least the following technical effects or advantages:

[0062] Because a rotating handle 6 is provided on the adjusting screw 4, it is convenient, quick and easy to adjust the length of the support rod by rotating the adjusting screw 4, which saves time and effort and improves work efficiency.

[0063] The working process of this embodiment:

[0064] At the weld seam or bevel, align one clamping seat 1 along with its internal wooden block with the weld seam. Place two other clamping seats 1 inside. Adjust the adjusting screw 4 and use the stability of the triangle and the friction between the wooden block and the metal to press and fix the weld seam.

[0065] If it is a regular circular inner cylinder, align one clamping seat 1 along with its internal wooden block with the seam of the plate to be welded, and arrange the other two clamping seats 1 along with the support rod and adjusting screw 4 in a temporary parallel arrangement. Adjust the adjusting screw 4 to achieve the clamping and fixing of the bench.

[0066] In summary, it can achieve the clamping and fixing of thin plates welded inside both regular and irregular inner cylinders.

[0067] It is worth noting that all contents not described in detail in the specification are existing technologies known to those skilled in the art, and the model parameters of fixing screw I3, adjusting screw 4 and fixing screw II5 are not specifically limited and can be determined using conventional technology. Electrical control components not mentioned in this technical solution are not shown in the figure because they are existing technologies, and will not be described here.

[0068] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
