[0002] In the current field of electrical control, electrical cabinets are used in almost every project, and the quantity is very large. It's common for electrical control cabinets to have multiple or incorrectly drilled holes. Once an incorrect hole is drilled, the panel is essentially unusable, or it needs to be returned to the original factory for repair welding, grinding, and painting, increasing time and transportation costs. Therefore, there is an urgent need for a hole-filling machine that can handle repair welding, grinding, and painting. Summary of the Invention

[0005] (II) Technical Solution

[0006] To address the aforementioned problems, the present invention provides a portable hole-filling, grinding, and painting integrated machine, which includes: a rotary table, a grip bracket, a painting component, a grinding component, and a friction welding component;

[0035] To better explain and facilitate understanding of the present invention, the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0036] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indication will also change accordingly.

[0037] Furthermore, in this invention, descriptions involving "first," "second," etc., are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this invention, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0038] In this invention, unless otherwise explicitly specified and limited, the terms "connection," "fixed," etc., should be interpreted broadly. For example, "fixed" can mean a fixed connection, a detachable connection, or an integral part; it can mean a mechanical connection or an electrical connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0039] The present invention provides a portable hole filling, grinding and painting all-in-one machine, which includes: a rotary disk 1, a grip bracket 2, a painting component 3, a grinding component 4 and a friction welding component 5.

[0040] A first tooling cylinder 11, a second tooling cylinder 12, and a third tooling cylinder 13 are provided on the first side of the rotating disk 1. A painting assembly 3, a grinding assembly 4, and a friction welding assembly 5 are respectively installed inside the first tooling cylinder 11, the second tooling cylinder 12, and the third tooling cylinder 13. The painting assembly 3 includes a nozzle 31 located on the second side of the rotating disk 1, the grinding assembly 4 includes a rotatable grinding disc 41 located on the second side of the rotating disk 1, and the friction welding assembly 5 includes a rotatable friction welding disc 51 located on the second side of the rotating disk 1. The rotating disk 1 is rotatably mounted on a holding bracket 2, and an abutment plate 21 is provided on the holding bracket 2. When the rotating disk 1 rotates, the first tooling cylinder 11, the second tooling cylinder 12, and the third tooling cylinder 13 can all abut against the abutment plate 21.

[0041] In this design, the rotation of the rotary disk 1 allows any one of the first tooling cylinder 11, the second tooling cylinder 12, and the third tooling cylinder 13 to abut against the abutment plate 21 on the holding bracket 2. This ensures that during the welding, grinding, and painting processes, the external force on the friction welding pad 51 and the grinding disc 41 is transferred to the holding bracket 2, guaranteeing the normal operation of the welding, grinding, and painting processes. Furthermore, by mounting the painting assembly 3, the grinding assembly 4, and the friction welding assembly 5 on the rotary disk 1 via the first tooling cylinder 11, the second tooling cylinder 12, and the third tooling cylinder 13 respectively, the portable hole repair, grinding, and painting integrated machine of this application simultaneously possesses the functions of welding, grinding, and painting. It should also be noted that in this design, the friction welding pad 51 achieves hole repair by rotating and rubbing against the inner wall of the enlarged hole on the cabinet. The grinding disc 41 can remove burrs, and the gripping bracket 2 can be held by a robot or a person. When the gripping bracket 2 is held by the robot, it can reduce the number of times the end tools need to be changed during the welding process of the cabinet (in the prior art, welding, grinding and painting all require different tools to be installed at the end of the robot), and achieve high-efficiency hole filling.

[0042] Furthermore, a rotating shaft 14 is provided on the first side of the rotating disk 1, and a switching cylinder 22 is provided on the gripping bracket 2. The rotating shaft 14 is rotatably mounted inside the switching cylinder 22, and a worm gear 15 is fixedly provided at the end of the rotating shaft 14 away from the rotating disk 1. A worm gear 23 that meshes with the worm gear 15 is rotatably provided inside the switching cylinder 22. One end of the worm gear 23 is connected to a function switching motor, which can drive the worm gear 23 to rotate around its own axis.

[0043] In the above scheme, the worm gear 23 drives the turbine 15 to rotate, which in turn drives the rotating shaft 14 to rotate, ultimately realizing the rotation of the rotating disk 1. Any one of the first tooling cylinder 11, the second tooling cylinder 12, and the third tooling cylinder 13 abuts against the abutment plate 21, enabling the switching between the three functions of welding, grinding, and painting. In addition, the worm gear 23 can drive the turbine 15 to rotate, but the turbine 15 cannot drive the worm gear 23 to rotate. Utilizing the self-locking property of the turbine 15 and the worm gear 23, the rotating disk will not rotate under the action of external force when any one of the friction welding pad 51, grinding disc 41, and nozzle 31 is working, ensuring the normal operation of the hole repair work.

[0044] In a preferred embodiment, a mounting base is fixedly installed inside the switching cylinder 22. A switching hole is provided through the mounting base, and a switching bearing is installed within the switching hole. The inner ring of the switching bearing is fitted onto the rotating shaft 14. The switching bearing and the switching hole are both interference-fitted, ensuring that the switching bearing is securely fixed in the switching hole without axial displacement. Alternatively, a shoulder, bushing, or retaining ring can be provided on the rotating shaft 14 to ensure that axial displacement between the rotating shaft 14 and the switching bearing does not occur while the rotating shaft 14 can rotate normally.

[0045] Furthermore, the painting assembly 3 also includes a paint tank 32 connected to the nozzle 31, which stores high-pressure paint. The painting assembly 3 also includes a linear propulsion unit fixedly disposed within the first tooling cylinder 11. The paint tank 32 is fixedly disposed on the linear propulsion unit, which can push the paint tank 32 and the nozzle 31 to extend or retract into the first tooling cylinder 11. The linear propulsion unit can be a linear motor; using the linear motor to drive the nozzle 31 ensures effective painting.

[0046] The grinding assembly 4 also includes a grinding motor and a grinding shaft. The grinding motor is fixedly installed inside the second tooling cylinder 12, the grinding shaft is rotatably connected to the second tooling cylinder 12, one end of the grinding shaft is fixedly connected to the output shaft of the grinding motor, and the other end of the grinding shaft is fixedly provided with a grinding disc 41.

[0047] In addition, the friction welding assembly 5 also includes a friction motor and a friction shaft. The friction motor is fixedly installed inside the third tooling cylinder 13, and the friction shaft is rotatably connected to the third tooling cylinder 13. One end of the friction shaft is fixedly connected to the output shaft of the friction motor, and the other end of the friction shaft is fixedly connected to the friction welding pad 51. In this embodiment, the friction motor drives the friction welding pad 51 to rotate at high speed. The friction between the friction welding pad 51 and the hole on the cabinet generates a heat source. When the temperature is too high, the friction welding pad 51 melts into the hole on the cabinet, achieving the effect of repair welding.

[0048] The friction pad 51 includes a pad body 52 and multiple wedge blocks 53. The pad body 52 is cylindrical, and the wedge blocks 53 are evenly arranged on the circumferential surface of the pad body 52. ​​Multiple grooves are also provided on the surfaces of the wedge blocks 53 opposite to the pad body 52. ​​When the friction pad 51 is in operation, the wedge blocks 53 first contact the inner wall of the hole. The placement of the wedge blocks 53 on the circumferential surface of the pad body 52 facilitates better friction and heat generation with the inner wall of the hole when the pad body 52 rotates.

[0049] Finally, flanges 16 are provided at the contact points between the first tooling cylinder 11, the second tooling cylinder 12, and the third tooling cylinder 13 and the abutment plate 21. Corresponding through holes are provided on both the flanges 16 and the abutment plate 21. By using fasteners passing through the through holes in the flanges 16 and the abutment plate 21, the connection between any one of the first tooling cylinder 11, the second tooling cylinder 12, and the third tooling cylinder 13 and the abutment plate 21 can be more securely locked.

[0050] It should be understood that the above description of specific embodiments of the present invention is only for illustrating the technical approach and features of the present invention, and is intended to enable those skilled in the art to understand the content of the present invention and implement it accordingly. However, the present invention is not limited to the specific embodiments described above. All changes or modifications made within the scope of the claims of the present invention should be covered within the protection scope of the present invention.
