[0002] Welding is a manufacturing technology that uses heat, high temperature or high pressure to join metals or other thermoplastic materials. In order to facilitate welding, it is sometimes necessary to adjust the workpiece to be welded to a specific height before welding. For example, vacuum welding is a protective welding method that can ensure that the welded parts at the welding point will not oxidize and the welding quality is high; the workpiece to be welded needs to be adjusted to the optimal welding height before vacuum welding to achieve the best welding effect.

[0003] The existing method of adjusting the welding height is generally to add a pad under the workpiece to be welded. However, this method has safety hazards, and the adjustment operation is inconvenient, and the adjusted height cannot be accurately known. The existing method also uses an electric lifting platform to adjust the height, but the device is complex and the cost is high. Utility Model Content

[0006] In this solution, the lifting and lowering of the upper cover is achieved by adjusting the position of the positioning column in the slide slot, thereby achieving the adjustment of the height of the workpiece to be welded.

[0007] Furthermore, in order to facilitate the movement of the tooling, a handle is provided on the base.

[0008] Furthermore, the elevated upper cover is enclosed by four side panels and a top panel, and each side panel is provided with a slide groove; the slide groove corresponds to the positioning column one by one.

[0009] Furthermore, the positioning column is connected to the lifting upper cover through a nut.

[0010] Furthermore, the tooling is also provided with a ruler hole for inserting a ruler to achieve measurement of welding height.

[0011] Furthermore, the scale hole is a through hole that penetrates the raised upper cover and the base.

[0012] Another object of the present invention is to provide a vacuum welding chamber, wherein the welding chamber comprises a welding platform, and the welding tooling that can be freely raised is provided on the welding platform.

[0013] Furthermore, the tooling is detachably connected to the welding platform.

[0014] Furthermore, the base is connected to the welding platform via bolts.

[0015] Compared with the prior art, one or more of the above technical solutions can achieve at least one of the following beneficial effects:

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] Example 1

[0027] like Figure 1 , Figure 2 As shown, this embodiment provides a welding tool that can be freely elevated, including a base 1 and an elevated upper cover 2 sleeved on the base 1.

[0028] The base 1 is provided with a positioning column 11 and a handle 12. As a specific embodiment, Figure 3 , Figure 4 As shown, the base 1 is a square structure, and positioning columns 11 are provided on the four side walls; handles 12 are arranged on a pair of side edges at the bottom of the base 1, and the handles 12 facilitate the overall movement of the tooling.

[0029] The lifting cover 2 is provided with a slide groove 21 that can accommodate the positioning column 11 to slide along the height direction, and the positioning column 11 passes through the slide groove 21 and is connected to the lifting cover 2. As a specific implementation method, Figure 1 , Figure 5 As shown, the raised cover 2 is enclosed by four side panels and a top panel, and the size of the enclosed square structure is adapted to the base 1, and each side panel is provided with a slide groove 21. The slide groove 21 corresponds to the positioning column 11. The positioning column 11 passes through the slide groove 21 and is connected to the raised cover 2 through a nut.

[0030] The length of the chute 21 can be set according to the height of the workpiece to be welded. In a specific embodiment, the tooling can be freely raised to any height between 300-600 mm.

[0031] The tooling is also provided with a ruler hole 22 for inserting a ruler. The ruler hole 22 is arranged at the center of the tooling. The ruler hole 22 is a through hole that penetrates the raised upper cover 2 and the base 1.

[0032] The working principle of this embodiment is as follows:

[0033] The workpiece to be welded is set on the lifting cover 2. When the welding height needs to be adjusted, the nut on the positioning column 11 is loosened, and the lifting cover 2 is moved, so that the positioning column 11 moves on the slide 21; after the workpiece to be welded is adjusted to an appropriate height, the positioning column 11 and the lifting cover 2 are fixed by the nut, so that the lifting cover 2 is fixed relative to the base 1, so as to adjust the welding height. Insert the ruler into the ruler hole 22 to read the welding height.

[0034] The freely elevating welding tool of this embodiment can freely adjust the welding height and has a simple structure, low cost and easy engineering manufacturing.

[0035] Example 2

[0036] like Figure 6 As shown, this embodiment provides a vacuum welding chamber. The vacuum welding chamber is sealed by a welding door 7, and the interior of the vacuum welding chamber includes a welding platform 4, a welding chamber 5 arranged above the welding platform 4, and a welding lens 6 connected to the welding chamber 5. The welding platform 4 is provided with a freely elevating welding tool 3 in embodiment 1. The welding tool 3 is detachably connected to the welding platform 4, and specifically, the welding platform 4 is connected to the base 1 by bolts.

[0037] In this scheme, the workpiece to be welded needs to be placed on the welding tooling 3 in the vacuum welding chamber, and the welding lens 6 is used to focus on the workpiece to be welded. The height of the welding tooling 3 is adjusted to find the optimal welding height. After finding the optimal welding height, vacuum welding is performed at this height.

[0038] The vacuum welding chamber adopts a detachable connection between the welding tool 3 and the welding platform 4, and the welding height of the workpiece to be welded is adjusted by the welding tool 3, and the adjustment method is flexible and stable. Specifically, compared with the pad adjustment method, it avoids safety hazards, and is convenient to record the adjusted height, thereby improving the work efficiency of vacuum welding; compared with the electric adjustment method, the structure of this embodiment is simple, the manufacturing is convenient, and the welding tool is detachable and flexible to use.
