Aluminum alloy door frame welding and grinding device

Abstract

The invention discloses an aluminum alloy door frame welding and grinding device, and relates to the technical field of welding machining equipment. The aluminum alloy door frame welding and grinding device comprises a main mechanism, a clamping and fixing device, a driving device and a grinding mechanism, the clamping and fixing device is fixedly installed at the bottom of the main mechanism, the driving device is installed in the main mechanism, the left end of the driving device extends to the outside of the main mechanism, and the grinding mechanism is movably installed at the left end of the driving device. According to the aluminum alloy door frame welding and grinding device, the device only needs to be arranged on the edge of a door frame and pressed, the clamping and fixing device can adapt to the width and height of the door frame, the whole device is stably clamped on the door frame, then the driving device is operated through the main mechanism to transversely move, the grinding mechanism can stably and effectively grind the included angle welding points of the aluminum alloy door frame, and the problems that due to unstable force control, excessive grinding is caused, and the welding points are damaged are solved.

Description

technical field [0001] The invention relates to the technical field of welding processing equipment, in particular to an aluminum alloy door frame welding and grinding device. Background technique [0002] Welding, also known as welding, is a manufacturing process and technique that uses heat, high temperature, or pressure to join metal or other thermoplastic materials such as plastics. [0003] Nowadays, the frames of some door frames are stamped and folded by aluminum alloy plates, and then welded. Since the corners of the door frames belong to welding points during welding, the narrow space is not convenient for people to polish the welding points. It is the right-angle turning point that people cannot control the force when using the grinding disc, and the force control is often unstable, resulting in excessive grinding, thus destroying the welding point. [0004] The second is that the grinding disc is at an angle, and there is no fixed fixture support. Even if it is f...

Problems solved by technology

[0003] Nowadays, the frames of some door frames are stamped and folded by aluminum alloy plates, and then welded. Since the corners of the door frames belong to welding points during welding, the narrow space is not convenient for people to polish the welding points. It is the right-angle turning point. People cannot control the force when using the grinding disc, and the force control is often unstable, resulting in excessive grinding, thus destroying the welding point.

[0004] The second is that the grinding disc is at an angle and there is no fixed fixture support. Even if it is fixed, the grinding disc cannot be used flexibly. Moreover, after the fixed grinding disc is in contact with the aluminum alloy, it is too direct to fit the aluminum alloy to grind the welding point. The high temperature of the grinding point will cause the metal powder produced by welding to adhere to the aluminum alloy, thereby affecting the space of the included angle, which is not convenient for the installation of the door frame, and is not beautiful. Therefore, a welding and grinding device for aluminum alloy door frame is invented to solve the above problems.
