Description

Technical Field

[0001] This utility model relates to the field of welding equipment technology, specifically a multifunctional vacuum welding device. Background Technology

[0002] Vacuum electron beam welding utilizes a directional, high-speed electron beam to strike the workpiece, converting kinetic energy into heat energy and melting the workpiece to form a weld. After being focused by an electromagnetic lens, it forms an electron beam with extremely high energy density. As the workpiece moves, a continuous weld seam is formed at the joint. For a vacuum electron beam welding machine, the workpiece to be welded is placed in a vacuum chamber and typically clamped on a worktable that can move linearly or rotate. The workpiece needs to be fixed to the worktable before being secured.

[0003] Currently, in practical applications, vacuum welding equipment on the market requires different clamping devices to clamp welded parts of varying shapes. These devices are not suitable for clamping welded parts of different shapes. Related technologies involve placing the welded part on a clamping plate, activating a bidirectional hydraulic rod to move the top plate outwards, which in turn moves the support rods on both sides outwards, the linkage plate inwards, and the rotating rod inwards. An arc-shaped block can fix cylindrical welded parts, and a pressure plate, under the force of a spring, will press and fix the cylindrical welded part. While this method can fix welded parts of different shapes, its application range is limited. It cannot achieve a clamping and fixing effect on irregular welded parts, thus having certain limitations and being inconvenient to use. Utility Model Content

[0025] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0026] It should be noted that all directional indications in the embodiments of the present application are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture. If the specific posture changes, the directional indication will also change accordingly.

[0027] In this application, unless otherwise specified or limited, the terms "connection" and "fixation" should be understood in a broad sense. For example, "fixation" can mean fixed connection, detachable connection, or integration; mechanical connection or electrical connection; direct connection or indirect connection through an intermediate medium; internal communication between two elements or interaction between two elements, unless otherwise specified. For those skilled in the art, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0028] In addition, the descriptions of "first", "second", etc. in this application are for descriptive purposes only and should not be understood as indicating or implying their relative importance or implicitly indicating the number of the technical features indicated. Therefore, the features defined as "first" or "second" may explicitly or implicitly include at least one of such features. In addition, the technical solutions between the various embodiments can be combined with each other, but this must be based on the fact that they can be implemented by ordinary technicians in this field. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by this application.

[0029] The workpiece is placed in a vacuum chamber and clamped. Then, a high-speed electron beam is directed to strike the workpiece, converting kinetic energy into heat energy and melting the workpiece to form a weld. After being focused by an electromagnetic lens, an electron beam with extremely high energy density is formed. The workpiece is then moved to form a continuous weld at the joint, thus completing the welding process.

[0030] In related technologies, by placing the welded parts on a clamping plate, opening a bidirectional hydraulic rod moves the top plate outward, which in turn moves the support rods on both sides outward, moves the linkage plate inward, and moves the rotating rod inward. The arc-shaped block can fix the cylindrical welded parts, and the extrusion plate, under the force of the spring, will press and fix the cylindrical welded parts. The arc-shaped block presses and fixes the welded parts, and the extrusion plate, under the force of the spring, can assist the arc-shaped block in pressing the welded parts. Although it can fix welded parts of different shapes, its application range is small. It cannot achieve a clamping and fixing effect on irregular welded parts, which has certain limitations and is inconvenient to use.

[0031] To address some of the problems in related technologies, this application provides a multifunctional vacuum welding device. When fixation is required, simply place the workpiece on the placement table 14, turn on the electric push rod 21 to make multiple round-head rods 23 contact the workpiece simultaneously, then turn on the electric push rod 25 to fix the position of the round-head rods 23 with the pressure plate 26. The round-head rods 23 fix the position of the workpiece, and then welding can be performed. This is more convenient and faster, improving the device's usability.

[0032] This application is described below with reference to the accompanying drawings and specific embodiments:

[0033] Combination Figure 1-Figure 3This application provides a multifunctional vacuum welding device, including a welding assembly 1. The welding assembly 1 includes: a welding chamber 11 on which a welding cylinder 12 is disposed; an observation tube 13 disposed on the welding cylinder 12; a placement platform 14 disposed inside the welding chamber 11; and a fixing assembly 2 disposed on the placement platform 14. The fixing assembly 2 includes: a first electric push rod 21 disposed on the placement platform 14; a plate 22 disposed on the first electric push rod 21; a round-headed rod 23 slidably connected inside the plate 22; a spring 24 sleeved on the round-headed rod 23, the round-headed rod 23 being connected to the plate 22 via the spring 24; a second electric push rod 25 disposed on the plate 22; and a pressure plate 26 slidably connected inside the plate 22 and fixedly connected to the output end of the second electric push rod 25.

[0034] In use, the workpiece is placed on the placement table 14, and then the electric push rod 21 is turned on, causing the output end of the electric push rod 21 to push the plate 22 to slide on the placement table 14, and drive the round-head rods 23 to slide until some of the round-head rods 23 first contact the workpiece. The workpiece pushes the round-head rods 23 into the plate 22 and squeezes the spring 24. After all the round-head rods 23 are in contact with the workpiece, the electric push rod 25 is turned on, causing its output end to drive the pressure plate 26 to slide. The pressure plate 26 contacts the round-head rods 23, which clamps and fixes the round-head rods 23. At this time, the multiple round-head rods 23 are in different positions and all are in contact with the workpiece, which has a good clamping and fixing effect on the workpiece. Then, the workpiece is welded by welding cylinder 12 and observation tube 13. During welding, the placement table 14 can move circumferentially and laterally to improve welding efficiency.

[0035] Specifically, a motor is installed inside the placement platform 14 and a transverse reciprocating sliding mechanism is installed inside the welding chamber 11, which are used to adjust the angle and transverse position of the placement platform 14.

[0036] In some embodiments, the fixing component 2 further includes an anti-slip pad 27 disposed on the pressure plate 26, which contacts the workpiece to improve the fixing effect.

[0037] In some embodiments, the round-headed rod 23 and the spring 24 are a set, and multiple sets are provided on the plate 22 to increase the applicability of the device.

[0038] In some embodiments, the anti-slip pad 27 is longer than the distance between the two outer round-head rods 23, so that the anti-slip pad 27 can contact the round-head rods 23 at any position.

[0039] In some embodiments, a disassembly assembly 3 is provided on the plate 22; the disassembly assembly 3 includes: a cylinder 31 disposed on the plate 22; a set bolt 32 threadedly connected to the cylinder 31, and the output end of the electric push rod 21 is inserted into the cylinder 31, and the set bolt 32 is inserted into the electric push rod 21.

[0040] In use, rotate the set bolt 32 so that it slides out from one end of the electric push rod 21 and pulls the plate 22 outward, causing the plate 22 to slide off the cylinder 31 from the electric push rod 21, thus disassembling the plate 22 and facilitating the maintenance of the internal structure of the plate 22.

[0041] In some embodiments, the plate 22 is flush with the top of the output end of the electric push rod 21, which facilitates welding of the product.

[0042] In some embodiments, the placement platform 14 is provided with two sets of fixing components 2, and multiple sets of fixing components 2 are used simultaneously to improve the fixing effect on the workpiece.

[0043] In some embodiments, the round-headed rods 23 are arranged horizontally and evenly to facilitate clamping of the workpiece.

In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples. In addition, those skilled in the art can combine and integrate the different embodiments or examples described in this specification.

[0045] In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the fact that ordinary technicians in this field can implement them. When the combination of technical solutions is mutually contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by this application.

[0046] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
