Description

Technical Field

[0001] This utility model belongs to the field of welding tooling technology, specifically relating to an adjustable angle plate butt welding tooling. Background Technology

[0002] In the field of welding technology, pre-welding preparation is crucial to welding quality. Among the many preparatory tasks, the assembly and clamping of the parts to be welded is particularly important. Without suitable welding fixtures to securely clamp the parts, resulting in excessive clearance or insecure clamping, various welding defects such as incomplete fusion, cracking, undercut, and misalignment can easily occur during welding. With the development of scientific research and the increase in welding methods, the demand for butt welding of flat plates with certain angles is gradually increasing. However, existing flat plate butt welding fixtures can only achieve butt welding of parts placed on the same plane, and cannot meet the welding needs of parts placed at different angles. Utility Model Content

[0003] The purpose of this invention is to solve the problem that existing flat plate butt welding fixtures cannot meet the welding requirements of workpieces with different angles, and to provide a flat plate butt welding fixture that is simple in structure, easy to use, and adjustable in angle.

[0004] To achieve the above objectives, the technical solution provided by this utility model is as follows:

[0005] This utility model provides an adjustable angle plate butt welding fixture, including a base plate, a screw mechanism, a slide rail mechanism, and two welding platforms;

[0006] The base plate is used to support the screw mechanism, the slide rail mechanism and two welding platforms on top. The two welding platforms are used to clamp the parts to be welded and are respectively the first welding platform and the second welding platform. One end of the first welding platform is hinged to the base plate and the second welding platform is hinged to the other end of the first welding platform.

[0007] The screw mechanism includes a screw and a nut. The screw is rotatably mounted to the base plate parallel to it. The nut is sleeved on the screw and can move along the screw. It is connected to the first welding platform through a connecting rod so that the angle of the first welding platform relative to the base plate can be adjusted by rotating the screw.

[0008] The slide rail mechanism includes a slide rail and a slider. The slide rail is fixed to the base plate in parallel with the screw. The slider can slide along the slide rail and is hinged to the second welding platform. Thus, when the first welding platform rotates relative to the base plate, the second welding platform is driven to move and rotate relative to the base plate, thereby changing the docking angle between the first welding platform and the second welding platform.

[0009] Furthermore, the screw mechanism is located in the middle of the width direction of the base plate, and the screw extends along the length direction of the base plate; there are two slide rail mechanisms, which are symmetrically arranged on both sides of the screw.

[0010] Furthermore, the welding fixture also includes two bearing housings for rotatably mounting the screw and bearings located within the bearing housings. The two bearing housings are fixed to the base plate at both ends of the screw, and the two ends of the screw pass through the corresponding bearings.

[0011] Furthermore, the welding fixture also includes two sets of hinge components for achieving a hinged connection between the first welding platform and the base plate. The two sets of hinge components are symmetrically connected to both sides of the first welding platform about the screw and are adjacent to the corresponding slide rails. Each set of hinge components includes a first hinge seat, a second hinge seat, and a rotating shaft. The first hinge seat is a lug that is vertically connected to the first welding platform. The second hinge seat includes two mounting plates that are vertically connected to the base plate. The two mounting plates are parallel to each other and sandwich the lug in the middle. The rotating shaft passes through the two mounting plates and the lug.

[0012] Furthermore, the docking angle between the first welding platform and the second welding platform is within the range of 0° to 180°.

[0013] Furthermore, two parallel protrusions are machined at both ends of the connecting rod, and a lug is radially connected to the outer circumferential surface of the nut. The lug is inserted between the two protrusions, and the hinge shaft passes through the two protrusions and the lug.

[0014] The advantages of this utility model are:

[0015] This utility model discloses an adjustable-angle plate butt welding fixture. The first welding platform is hinged to a base plate and connected to it via a screw mechanism, allowing it to pivot relative to the base plate under the rotational drive of the screw. One end of the second welding platform is hinged to the first welding platform, and the other end is hinged to a slider in a slide rail mechanism, with the slide rail parallel to the screw. Therefore, when the screw rotates, the nut translates along the screw, causing the first welding platform to rotate relative to the base plate. The first welding platform then drives the second welding platform to move. The second rotating platform rotates relative to the base plate while moving along the slide rail with the slider. This changes the butt welding angle of the two welding platforms, enabling butt welding of workpieces at different angles and meeting the welding requirements of workpieces with varying angles.

Detailed Implementation

[0022] The present invention will now be described in detail with reference to the accompanying drawings and exemplary embodiments thereof. It should be noted that the following detailed description of the present invention is for illustrative purposes only and is not intended to limit the scope of the invention.

[0023] It should be noted that, in the context of this utility model, the terms "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "inner," "outer," "clockwise," and "counterclockwise," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0024] Furthermore, terms such as "first" and "second" are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.

[0025] This utility model provides an adjustable angle plate butt welding fixture, which is simple in structure, easy to operate, and highly practical. It can realize plate butt welding at different angles, reduce the instability of temporary simple fixtures, and thus improve the welding quality.

[0026] Reference Figures 1 to 3The adjustable-angle flat plate butt welding fixture, as an exemplary embodiment of this utility model, may include a base plate 1, a screw mechanism 2, a slide rail mechanism 3, and two welding platforms, namely a first welding platform 4 and a second welding platform 5. The base plate 1 supports the screw mechanism 2, the slide rail mechanism 3, and the two welding platforms above it. The two welding platforms are used to clamp the parts to be welded, particularly through… Figure 4 The clamping device shown clamps the workpiece to be welded onto the welding platform. This clamping device is movable, its position is adjustable, and it can be manufactured in different sizes to accommodate the joining of plates of different sizes. This fixture, under the action of the screw mechanism 2, the slide rail mechanism 3, and various connecting structures, can... Figure 1 Two of the welding platforms shown are in a 0° orientation with Figure 3 The two welding platforms shown can switch between 180° positions, meaning that the docking angle between the two welding platforms in this invention can vary within the range of 0° to 180°. Figure 2 The tooling posture with two welding platforms at a 60° butt joint angle is shown.

[0027] The base plate 1 is specifically a platform with parallel upper and lower surfaces and uniform thickness. To ensure load-bearing strength and prevent rust, the base plate 1 is preferably made of stainless steel, with a length of 300mm-500mm, preferably 400mm, a width of 300mm-500mm, preferably 400mm, and a thickness of 20mm-30mm, preferably 20mm.

[0028] One end of the first welding platform 4, i.e., the left end in the figure, is hinged to the base plate 1. One end of the second welding platform 5 is hinged to the other end of the first welding platform 4, and the other end of the second welding platform 5 is hinged to the slide rail mechanism 3, thereby realizing the linkage of the two welding platforms. When the two welding platforms are at a 0° docking angle, they are vertically parallel to each other. When they are at a 180° docking angle, they are adjacent to each other and in the same horizontal plane. Both welding platforms can be platforms with parallel upper and lower surfaces and the same thickness. The material of the welding platforms can be stainless steel. To avoid reducing the rigidity of the welding platforms and the tensile force on the base plate, the thickness of the welding platforms is preferably 10mm.

[0029] To reliably achieve a hinged connection between the first welding platform 4 and the base plate 1 with a simple structure, such as Figure 2Clearly shown, the welding fixture also includes a hinge assembly 7, which comprises a first hinge seat, a second hinge seat, and a pivot. The first hinge seat is a lug 71 vertically connected to the first welding platform 4. The lug 71 can be a separate component welded to the welding platform, or it can be an integral part of the welding platform. The second hinge seat includes two mounting plates 72 vertically connected to the base plate 1. The mounting plates 72 can also be separate components or part of the base plate 1. The two mounting plates 72 are parallel to each other and clamp the lug 71 in the middle. The pivot 73 passes through the two mounting plates and the lug 71, thereby rotatably connecting the first welding platform 4 to a certain distance above the base plate 1.

[0030] The screw mechanism 2 includes a screw 21 and a nut 22. The screw 21 is rotatably mounted to the base plate 1 parallel to it. The screw mechanism 2 is specifically located at the center of the base plate 1 in the width direction, and the screw 21 extends along the length direction of the base plate 1.

[0031] To reliably and conveniently achieve rotatable installation of the screw 21 on the base plate 1, the welding fixture of this utility model also includes two bearing seats 6 fixed to the base plate 1 at both ends of the screw 21 and bearings (such as deep groove ball bearings with sealing rings on both sides (contact type)) located in the bearing seats 6, with the two ends of the screw 21 passing through the corresponding bearings.

[0032] Nut 22 is fitted onto screw 21 and can translate along screw 21. It is connected to the first welding platform 4 via connecting rod 23, specifically at the bottom center of the first welding platform 4, so that the angle of the first welding platform 4 relative to the base plate 1 can be adjusted by rotating screw 21. Specifically, when screw 21 is rotated, the nut 22 that mates with it translates along screw 21, and the connecting rod 23 connected to nut 22 is pulled or pushed, thereby causing the first welding platform 4, which is linked to connecting rod 23, to pivot relative to the base plate 1.

[0033] To facilitate the function of connecting rod 23 pivoting relative to base plate 1 with nut 22, such as Figure 2 As clearly visible, two parallel protrusions 231 are machined at both ends of the connecting rod 23, and lugs 221 are radially connected to the outer circumferential surface of the nut 22. The lugs 221 are inserted between the two protrusions 231, and the hinge shaft passes through the two protrusions 231 and the lugs 221. A similar hinge connection structure can also be used between the connecting rod 23 and the first welding platform 4. In addition, the hinges at both ends of the second welding platform 5 can also adopt this structure. However, this is not intended to limit the present invention, and other different structures can also be used to achieve the hinge of the two components.

[0034] The slide rail mechanism 3 includes a slide rail 31 and a slider 32. The slide rail 31 is fixedly connected to the base plate 1 in parallel with the screw 21. In an exemplary embodiment of this utility model, there are two slide rail mechanisms 3, which are symmetrically arranged on both sides of the screw 21. This structure can ensure the smooth movement of the welding platform and improve the working reliability of the tooling. In this regard, the hinge assembly 7 mentioned above has two sets, which are symmetrically connected to the front and rear sides of the first welding platform 4 about the screw 21 and adjacent to the corresponding slide rail 31. In this way, the mounting plate 72 in the hinge assembly 7 can also be used as a limiting component for the slider 32.

[0035] The slider 32 can slide along the slide rail 31 and is hinged to the right end of the second welding platform 5. With this structure, when the first welding platform 4 rotates relative to the base plate 1, the second welding platform 5 is driven to move left and right relative to the base plate 1 and change its angle, thereby altering the docking angle between the first welding platform 4 and the second welding platform 5. Therefore, this fixture uses a hinge to achieve linkage between the left and right welding platforms, and through connecting rods, slide rail mechanisms, and screw mechanisms, it achieves linkage between the left and right welding platforms relative to the base plate. This allows for precise adjustment of the angle between the welding platform and the base plate, enabling angle changes between the welding platforms from 0° to 180°, thus allowing welding of parts placed at different angles.

[0036] The working principle of the adjustable-angle plate butt welding fixture provided by this utility model is as follows: First, it can adopt... Figure 4 The clamping device shown fixes the plates to be welded on two welding platforms. Then, the angle of the left and right welding platforms is adjusted to a suitable position by the screw mechanism 2 so that the areas of the two plates to be welded can fit tightly together. Then, the workpiece joints are aligned and fixed, and welding or laser cladding can begin.

[0037] Therefore, as described above, this flat plate butt welding fixture allows for angle adjustment between the two welding platforms and the fixed base plate via a screw mechanism. The position of the second welding platform can change with the platform angle via a slide rail. Thus, by adjusting the butt angle of the two welding platforms, flat plate butt welding at different angles can be achieved, meeting the welding requirements of workpieces with different angles. Simultaneously, it reduces the instability of temporary simple fixtures, thereby improving welding quality.

[0038] Finally, it should be noted that the features mentioned and / or shown in the above description of exemplary embodiments of the present invention can be combined in the same or similar manner with one or more other embodiments, combined with features in other embodiments, or substituted for corresponding features in other embodiments. These combined or substituted technical solutions should also be considered as included within the protection scope of the present invention.
