An aluminum alloy door frame welding and grinding device

Abstract

The invention discloses a welding and grinding device for an aluminum alloy door frame, and relates to the technical field of welding processing equipment. The aluminum alloy door frame welding and grinding device includes a main mechanism, a clamping and fixing device, a driving device and a grinding mechanism. The bottom of the main mechanism is fixed with a clamping and fixing device, and the inside of the main mechanism is equipped with a driving device. The left end of the driving device extends to the outside of the main mechanism, and a grinding mechanism is movably installed on the left end. The aluminum alloy door frame welding and grinding device only needs to place the device on the edge of the door frame, press the device, and the clamping and fixing device will adapt to the width and height of the door frame, so that the whole device can be stably clamped on the door frame. The mechanism operates the horizontal translation of the driving device, so that the grinding mechanism can stably and effectively grind the welding joints of the aluminum alloy door frame angles, avoiding the instability of force control, which will cause excessive grinding and damage the welding joints.

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.
