[0037] The round tube grinding assembly and the top screw of the vertical mounting plate of the angle grinder form a fillet grinding module installed on the longitudinal axis rotating plate B. The surface of the round tube is ground. By controlling the downward pressure, the grinding intensity and grinding area can be controlled. By manually rotating the round tube, all surfaces can be ground once. The round tube grinding assembly is driven by the angle grinder to drive the sanding belt driving wheel. In the triangle composed of a sanding belt driving wheel and two sanding belt driven wheels, the sanding belt is driven to move. During the working process, the sanding belt mounting frame B always keeps the sanding belt in a tensioned state under the action of the tension spring. When the round tube grinding module is pressed down, the sanding belt mounting frame B can be swung to keep the sanding belt in a suitable tensioned state.

[0038] When in use, firstly, by installing the vertical beam 3, the cross beam 13 and the longitudinal beam 4, the manual winch 16, the steel wire 15 and the related guide rail sliders, the machine head can be moved and stopped in the XYZ direction of space at will. The third slider 5 of the longitudinal beam 4 is installed by hoisting, which improves the operating space and increases the processing stroke. The wire drawing machine 29 and the wire drawing machine 29 head mounting frame form a processing module that is replaced as a whole with the remaining processing process modules.

The wire drawing machine 29, the wire drawing machine head mounting frame 28, and the fixed top screw 27 constitute a wire drawing module; the electric grinder 40, the electric grinder mounting frame 38, the electric grinder V-shaped mounting frame 39, the V-shaped clamp 42, and the electric grinder pressing plate 41 constitute an internal fillet grinding module; the fillet grinding assembly 43, the workpiece positioning block 44, and the fixed top screw 27 constitute an external fillet grinding module; the angle grinder 46, the angle grinder horizontal mounting plate 45, and the fixed top screw 27 constitute a weld grinding and polishing module; the angle grinder 46, the arc grinding assembly 48, the angle grinder vertical mounting plate 47, and the fixed top screw 27 constitute a round pipe and arc grinding module; the angle grinder 46, the cutting grinding wheel 57, the angle grinder vertical mounting plate 47, and the fixed top screw 27 constitute a steel plate groove cutting module. The above modules can be combined and switched in various ways to achieve multiple processes completed separately on one device. This avoids the waste of continuous transportation and increasing corresponding special functional equipment. At the same time, due to the application of various guide rails, the processing accuracy of the wire drawing, grinding and cutting process can far exceed that of human-held power tools, effectively improving the accuracy and aesthetics of the product. A constant pressure tension spring 24 is designed in the head part. During the working process, the longitudinal beam rotating plate B22 is rotated around the rotating plate mounting shaft 36 through the rotating plate mounting shaft 36, the bearing seat 35, the longitudinal beam rotating plate B22, and the limit screw 26, thereby driving the wire drawing machine 29 and other functional parts and the workpiece to always be in a fitting state, and the processing surface will not be intermittent during the processing due to manufacturing and installation errors. The size and number of the tension spring 53 can be adjusted to control the downward pressure between the working processing head and the workpiece surface. When the processing surface needs to be strictly horizontal, the limit screws 26 on both sides can be used to adjust the appropriate position of the longitudinal beam rotating plate B22 and fix it. At this time, it is in the position control state. The workpiece clamping platform is composed of a brush plate 9, a table 7, a fixture fixing plate 8, a quick clamp fixing plate 10, a quick clamp 11 and a baffle 12. The fixture fixing plate 8 is provided with a pressure riveted nut column, the height of which is lower than the thickness of the brush plate 9, and the screws are pre-installed, which can protect the surface of easily scratched materials such as stainless steel, and position them more quickly and reliably. If the workpiece is too heavy, a rubber pad 58 forms a force-bearing surface to prevent the workpiece from deforming the brush. Larger and heavier parts can be processed in a floor-standing manner.The universal dust suction device is composed of a universal dust suction head fixing frame 34, an optical axis, a fixed cross clamping seat 37, a rotating cross clamping seat 30, a dust suction hood 32, and a dust suction hood fixing frame 31. By adjusting the relative positions between the components, installing them to a better dust suction position, and fixing them, driven by the longitudinal beam 4 and the machine head, it moves with the movement of the processing area, effectively improving the dust suction effect, which can be achieved by using a smaller dust suction motor. It saves energy loss during the dust suction process. In the specific production process, more functions can be completed by designing corresponding tooling and fixtures by the user. For example, semi-automatic welding, semi-automatic punching, etc. Or a more convenient operation method can be achieved by using a motor to drag. The possibility of subsequent product upgrades is greatly improved.

[0039] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
