[0002] Steel bar welding is to connect steel bars axially or crosswise by using electric welding equipment. The quality of steel bar welding is related to the weldability of steel and welding technology. The weldability is related to alloy elements such as carbon, manganese, and titanium in the steel bar. The electric welding process includes welding parameters and operation level. Due to factors such as humid storage environment, rust sometimes appears on the surface of the steel bar. In order to ensure the welding quality, the rust on its surface will be treated.

[0003] During the rust removal process of steel bars, traditional rust removal methods often use manual hand-held grinding devices to process them.

One side of the first pulley 52 is fixedly connected to an installation cylinder 53. The outer wall of the installation cylinder 53 is fixedly connected to a first grinding disc 54. The installation cylinder 53 is rotationally connected to the through hole opened in the support frame 2 through it. The installation cylinder 53 is slidably connected to a slide bar 55 through the groove opened in it. The outer wall of the slide bar 55 is fixedly connected to a second grinding disc 56. One side of the second grinding disc 56 is fixedly connected to a plain bearing 57. The other side of the plain bearing 57 is fixedly connected to a connecting rod 58. The connecting rod 58 is slidably connected to the through hole opened in the housing 1 through it. A spring 59 is provided on the outer wall of the connecting rod 58. One end of the spring 59 is connected to one side of the plain bearing 57, and the other side of the spring 59 is connected to the inner wall of the housing 1;

[0028] The specific implementation method is as follows: When grinding is required, start the motor 51 to drive the installation cylinder 53 to rotate, thereby driving the first grinding disc 54 to rotate. At the same time, the rotation of the installation cylinder 53 drives the slide bar 55 to rotate, thereby driving the second grinding disc 56 to rotate. When grinding, one end of the steel bar is placed between the first grinding disc 54 and the second grinding disc 56, and a certain extrusion is applied to it, so that the second grinding disc 56 moves and the spring 59 is compressed, so that the second grinding disc 56 is in close contact with the steel bar through the spring 59;

[0029] The cleaning assembly 4 includes a base 44. The top end of the base 44 is fixedly connected to the housing 1. A material receiving groove 41 is slidably connected in the base 44. One side opening of the material receiving groove 41 is fixedly connected to a filter screen 42. A blower 46 is fixedly connected in the through hole opened on one side of the base 44.

The other end of the belt 43 is slidably connected to the first pulley 52.

[0030] The specific implementation method is as follows: When grinding, the motor 51 drives the first pulley 52 to rotate, thereby driving the second pulley 45 to rotate through the belt 43, so that the blower 46 rotates and operates, so that the dust generated during the grinding process is sucked into the material receiving groove 41 through the filter screen 42 and the through holes opened in the baffle 3.

[0031] Working principle: When grinding is required, start the motor 51 to drive the mounting cylinder 53 to rotate, which in turn drives the first grinding disc 54 to rotate. At the same time, the rotation of the mounting cylinder 53 drives the sliding rod 55 to rotate, which drives the second grinding disc 56 to rotate. When grinding, place one end of the steel bar between the first grinding disc 54 and the second grinding disc 56 and apply a certain extrusion force to it, causing the second grinding disc 56 to move and compress the spring 59. Thus, the second grinding disc 56 is in close contact with the steel bar through the spring 59. During grinding, the motor 51 drives the first pulley 52 to rotate, which drives the second pulley 45 to rotate through the belt 43, causing the blower 46 to rotate and operate. Then, the dust generated during the grinding process is sucked into the material receiving groove 41 through the filter screen 42 and the through holes opened in the baffle 3. When cleaning is required, simply pull out the material receiving groove 41 to clean it.
