Description

Technical Field

[0001] The utility model belongs to the technical field of vacuum welding, in particular to a vacuum welding auxiliary device for titanium-based alloy and ceramics. Background Art

[0002] Vacuum welding refers to a high-temperature welding technology performed in a vacuum or reduced pressure environment. The principle of vacuum welding is to perform welding in an oxygen-free, water-free and impurity-free environment, thereby effectively avoiding problems such as oxidation and dehydrogenation, thereby obtaining high-precision and high-quality welding effects. Titanium-based alloys and ceramics belong to the category of vacuum welding processing, and vacuum welding of titanium-based alloys and ceramics needs to be operated on a vacuum welding device;

[0003] After searching, a patent document with patent announcement number CN218983561U discloses a vacuum chamber welding device, including a vacuum chamber welding body, which is the main part of the vacuum chamber welding device, and a mounting base is installed on the rear surface of the vacuum chamber welding device; an industrial vacuum cleaner is arranged on the upper end of the mounting base. The utility model overcomes the shortcomings of the prior art, and by setting a mounting base, an industrial vacuum cleaner, an industrial vacuum cleaner cover, a switch button, a vacuum hose and a dust collection cover, when the switch button is started to drive the industrial vacuum cleaner to work, the flowing air sucks the flux and welding slag generated during soldering into the barrel through the vacuum hose, making it more convenient to clean the welding slag, thereby reducing the flux and welding slag generated during soldering scattered in the cavity, making it more troublesome to clean the cavity. At the same time, if the residual flux and welding slag are not cleaned in time, it may affect the quality and use of welding materials.

[0004] However, it still has the following disadvantages in actual use:

[0005] In the above-mentioned vacuum chamber welding device, a vacuum chamber welding door is connected to the front side of the vacuum chamber welding body through a hinge. The vacuum chamber welding door is opened to load or unload the titanium-based alloy and the ceramic. However, during the welding process of the titanium-based alloy and the ceramic, the weldment needs to be heated and melted at a high temperature to achieve vacuum welding between the titanium-based alloy and the ceramic, which causes the temperature inside the vacuum chamber welding body to be high, which may cause damage to the hands of the staff who extend into the vacuum chamber welding body, thereby reducing the safety during operation;

[0006] 2. In the above-mentioned vacuum chamber welding device, a driving motor is arranged on the right side of the vacuum chamber welding body, a slide rail is arranged inside the vacuum chamber welding body, a slider is slidably connected to the left and right ends of the slide rail, a positive and negative threaded rod is rotatably connected inside the slide rail, and the driving motor is connected to the end of the positive and negative threaded rod, and the driving motor is started, the positive and negative threaded rod is rotated, and the distance between the two sliders is adjusted, thereby clamping the titanium-based alloy and the ceramic. However, it is inconvenient to adjust the height of the titanium-based alloy and the ceramic, and it is inconvenient to align the welding surfaces of the titanium-based alloy and the ceramic of different heights, thereby inconvenient to weld the titanium-based alloy and the ceramic.

[0007] To this end, we provide a titanium-based alloy and ceramic vacuum welding auxiliary device to solve the above-mentioned problems. Utility Model Content
