Description

Technical Field

[0001] The utility model relates to the technical field of vacuum brazing furnaces, in particular to a vacuum brazing furnace door pressing mechanism. Background Art

[0002] Vacuum brazing furnace is a welding technology performed in an oxygen-free environment. It is widely used in electronics, automobiles, aerospace and other fields. This welding method can achieve high-quality and high-precision welding joints with little pollution to the environment. Furnace door pressing is the process of fitting the furnace door tightly to the furnace body. This can ensure that the furnace door always remains closed during the welding process to prevent external impurities from entering the welding area and affecting the welding quality. In addition, since the welding process will generate a lot of heat and gas, furnace door pressing can also prevent these hot gases from leaking out, ensuring high temperature and low oxygen concentration in the welding environment.

[0003] After the furnace door and the furnace body are closed by the clamping mechanism of the existing vacuum brazing furnace door, a large amount of heat and gas will be generated in the furnace during the welding process, making the furnace door hot, resulting in the staff being unable to approach the furnace door in time for operation, causing inconvenience to the work.

When the limit rod 83 moves to the limit block 12, the limit rod 83 drives the spring 84 to be squeezed, and at the same time is inserted into the inside of the limit block 12. Then, the limit rod 83 and the limit block 12 are fixed by the push of the spring 84. When it needs to be opened, the cam rotator 85 is started through the external controller. When the cam rotator 85 rotates, it pushes the fixed column 86 to one side, and at the same time drives the limit rod 83 at the bottom to move, so that it is separated from the limit block 12.

It should be noted that the overall stability of the furnace body 1 can be increased by setting the diagonal braces 9 and the connecting columns 10.

[0026] Working principle: When in use, the electric cylinder 6 is started to rotate, and the closed door 3 is driven to close through the connecting seat 7. When the closed door 3 rotates, it drives the first fixed frame 41 to move, and the first fixed frame 41 drives the first rotating rod 42 to move. The first rotating rod 42 drives the first bevel gear 43 to rotate, and rotates through the support of the connecting frame 44 and the vertical gear 45. The vertical gear 45 drives the second bevel gear 48 to rotate while rotating. The second bevel gear 48 rotates through the second rotating rod 47, and then rotates through the support of the connecting frame 44 and the second fixed frame 46. When the closed door 3 is closed, the first fixed frame 41 drives the first rotating rod 42 to move, and the first rotating rod 42 drives the first bevel gear 43 to rotate. When closing, the limit frame 81 is driven to move, and the limit rod 83 is driven to move at the same time. When the limit rod 83 moves to the limit block 12, the limit rod 83 drives the spring 84 to be squeezed and inserted into the inside of the limit block 12. Then, the limit rod 83 is fixed to the limit block 12 by the push of the spring 84. When it is necessary to open, the cam rotator 85 is started by the external controller. When the cam rotator 85 rotates, it pushes the fixed column 86 to move to one side, and drives the limit rod 83 at the bottom to move, so that it is separated from the limit block 12, and then the closed door 3 is opened by the electric cylinder 6.
