Description

Technical Field

[0001] This utility model relates to the field of friction stir welding technology, and in particular to a friction stir welding workbench with an adjustable welding angle. Background Technology

[0002] Friction stir welding refers to the use of heat generated by the friction between a high-speed rotating welding tool and the workpiece to locally melt the materials to be welded. As the welding tool moves forward along the welding interface, the plasticized material flows from the front to the rear of the welding tool under the action of the rotational friction force of the welding tool, and forms a dense solid phase weld under the extrusion of the welding tool.

[0003] Most existing friction stir welding worktables are flat and their angle is not adjustable. This means that the angle of the workpiece to be welded cannot be adjusted during the friction stir welding process, and consequently, the welding angle cannot be adjusted. When it is necessary to adjust the welding angle, it is often necessary to place some supports between the worktable and the workpiece to adjust the welding angle, which is very inconvenient. Utility Model Content

[0004] This invention provides an adjustable welding angle friction stir welding workbench, which solves the technical problem that existing friction stir welding workbench cannot adjust the welding angle.

[0005] To achieve this technical objective, the present invention adopts the following solution: an adjustable welding angle friction stir welding workbench, comprising a base plate, an adjustable support mechanism, a sliding support mechanism, and a workbench body;

[0006] The workbench body is positioned above the base plate;

[0007] An adjustable support mechanism is located on the top of the base plate and is connected to one end of the worktable body for adjusting the height of one end of the worktable body.

[0008] The sliding support mechanism is slidably mounted on the top of the base plate, and its top end is rotatably connected to the bottom of the other end of the worktable body to support the other end of the worktable body.

[0009] Furthermore, the workbench body includes a tabletop, and two connecting plates are fixed at both ends of the bottom surface of the tabletop.

[0010] Furthermore, the adjustable support mechanism includes two spaced-apart support rods, which are fixed to the top of the base plate and extend vertically. The two support rods are connected by a connecting rod, and the support rods have arc-shaped through slots that extend vertically.

[0011] A sliding rod is slidably installed in the through groove. The sliding rod is rotatably connected to a connecting arm. The top of the connecting arm is rotatably connected to a drive rod. The two ends of the drive rod are slidably installed in the through groove. The drive rod and the connecting plate are rotatably connected.

[0012] The sliding rod is rotatably connected to one end of the drive cylinder, and the other end of the drive cylinder is rotatably connected to the base plate.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] This utility model is equipped with an adjustable support mechanism and a sliding support mechanism. The adjustable support mechanism can adjust the height of one end of the workbench body, while the sliding support mechanism fixes the other end of the workbench body, so that the height of the other end of the workbench body remains unchanged, thereby realizing the adjustment of the angle of the workbench body and thus the adjustment of the welding angle.

[0022] To fully understand the purpose, features and effects of this utility model, the following specific embodiments will be used to describe this utility model in detail, but this utility model is not limited thereto.

[0023] like Figures 1 to 2As shown, the present invention provides an adjustable welding angle friction stir welding workbench, including a base plate 1, an adjustable support mechanism 2, a sliding support mechanism 3, and a workbench body 4.

[0024] The workbench body 4 is positioned above the base plate 1;

[0025] The adjustable support mechanism 2 is located on the top of the base plate 1 and is connected to one end of the worktable body 4 for adjusting the height of one end of the worktable body 4.

[0026] The sliding support mechanism 3 is slidably mounted on the top of the base plate 1, and its top end is rotatably connected to the bottom of the other end of the worktable body 4 to support the other end of the worktable body 4.

[0027] Furthermore, the workbench body 4 includes a table surface 41, and two connecting plates 42 are fixed at both ends of the bottom surface of the table surface 41.

[0028] Furthermore, the adjustable support mechanism 2 includes two spaced-apart support rods 21, which are fixed to the top of the base plate 1 and extend vertically. The two support rods 21 are connected by a connecting rod 22, which reinforces the stability of the support rods 21. The support rods 21 have arc-shaped through slots 23 that extend vertically. In this embodiment, the through slots 23 bend to the left.

[0029] A sliding rod 24 is slidably provided in the through groove 23. The sliding rod 24 is rotatably connected to a connecting arm 25. The top of the connecting arm 25 is rotatably connected to a drive rod 26. The two ends of the drive rod 26 are slidably provided in the through groove 23. The drive rod 26 is rotatably connected to the connecting plate 42.

[0030] The sliding rod 24 is rotatably connected to one end of the drive cylinder 27, and the other end of the drive cylinder 27 is rotatably connected to the base plate 1.

[0031] Preferably, both ends of the sliding rod 24 and both ends of the driving rod 26 are provided with limiting disks 5 to prevent the sliding rod 24 and the driving rod 26 from sliding out of the through groove 23. The number of connecting arms 25 can be selected according to the actual situation. In this embodiment, three connecting arms 25 are provided. One connecting arm 25 is located in the middle of the sliding rod 24, and the other two connecting arms 25 are distributed at both ends of the sliding rod 24 with the middle connecting arm 25 as the symmetrical plane.

[0032] Furthermore, the sliding support mechanism 3 includes two spaced vertical rods 31, the bottom of the vertical rods 31 is slidably connected to the base plate 1, the tops of the two vertical rods 31 are connected by a horizontal rod 32, and the horizontal rod 32 is rotatably connected to the connecting plate 42.

[0033] As a way of sliding connection between the vertical rod 31 and the base plate 1, the top surface of the base plate 1 is provided with two parallel sliding grooves 11; the bottom of the vertical rod 31 is provided with a slider that matches the sliding groove 11, and the slider is slidably disposed in the sliding groove 11.

[0034] The working principle of this application is described in detail with the worktable body 4 in a horizontal state as the initial state. During use, the drive cylinder 27 extends, causing the sliding rod 24 to slide within the through groove 23, raising the sliding rod 24. The sliding rod 24 then moves the connecting arm 25 upwards, which in turn moves the drive rod 26 upwards, further raising the left side of the worktable body 4. Simultaneously, the right side of the worktable body 4 rotates relative to the horizontal bar 32. The height of the right end of the worktable body 4 is limited by the vertical bar 31 and the horizontal bar 32, allowing it to slide left and right only within the same horizontal plane. Meanwhile, the left end of the worktable body 4 rises, thus achieving the effect of rotation of the worktable body 4. During this process, the vertical bar 31 slides within the slide groove 11.

[0035] Finally, it should be noted that the above-listed embodiments are merely preferred embodiments of the present invention. Of course, those skilled in the art can make modifications and variations to the present invention. If such modifications and variations fall within the scope of the claims of the present invention and their equivalents, they should be considered as being within the protection scope of the present invention.
