[0002] CNC machining refers to a process of machining parts on CNC machine tools. CNC spraying machine is a type of CNC machining equipment. It sprays paint or coatings on the surface of parts in a fully automated manner to enhance the wear resistance and corrosion resistance of the parts' surface.

[0003] Existing fully automatic CNC spray machines, such as the machined CNC spray machine proposed in patent application number "CN202221608724.0", avoid spraying the workpiece body with a manual handheld spray gun through structures such as a base, a paint storage box, a spray gun, a delivery pump, and a slide rod, thereby ensuring the uniformity of the spraying of the workpiece body.

[0004] However, it can only spray the outer wall of the parts and is not suitable for parts that need to be sprayed on both the inner and outer walls. For example, buried steel pipes, both the inner and outer walls of the steel pipes need to be sprayed with paint to ensure the corrosion resistance of the steel pipes. If the inner and outer walls are not sprayed at the same time, the spraying efficiency will be low. Therefore, a fully automatic CNC spraying machine is proposed. Utility Model Content

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] A fully automatic CNC spraying machine, such as Figure 1-Figure 3 As shown, it includes a base assembly, and the two sides of the upper end of the base assembly are respectively fixed with a bracket 2 and a bracket 2 5, an inner spray assembly is rotatably connected between the bracket 1 2 and the bracket 2 5, a mounting cylinder 7 is fixedly connected to one side of the bracket 2 5, the inner spray assembly is located in the middle of the mounting cylinder 7, an outer spray assembly is slidably connected between the bracket 1 2 and the bracket 2 5, the outer spray assembly is located outside the mounting cylinder 7, a driving rod 12 is fixedly connected to the side wall of the inner spray assembly, and the outer spray assembly passes through the end of the driving rod 12.

[0023] The parts are installed by installing the cylinder 7, so that the parts similar to steel pipes are installed on the bracket 2 5. At this time, the inner spraying assembly is located in the middle of the part. The bracket 1 2 and the bracket 2 5 are fixed, and the rotation of the inner spraying assembly is controlled so that the inner spraying assembly can rotationally spray the inner wall of the part so that the inner wall of the part is evenly sprayed. While the inner spraying assembly rotates, the outer spraying assembly is pulled to rotate in a circular arc trajectory through the driving rod 12, so that the outer spraying assembly sprays around the outer wall of the part, so that the inner and outer walls of the part are sprayed evenly at the same time, and the parts are sprayed automatically with high spraying efficiency.

[0024] A servo motor 3 is fixedly connected to one side of the bracket 2, and a driving column 4 is fixedly connected to the output end of the servo motor 3. A center block 8 is fixedly connected to the side of the bracket 2 5 close to the bracket 2, and the center block 8 is located in the middle of the mounting tube 7. The internal spraying assembly includes a reciprocating screw rod 9, one end of the reciprocating screw rod 9 is driven by the driving column 4, and the other end is rotatably connected to the center block 8.

[0025] like Figure 1-Figure 3 As shown, the servo motor 3 drives the driving column 4 to rotate, and the driving column 4 penetrates the bracket 2. Since the driving column 4 is connected and matched with the reciprocating screw rod 9, the two are similar to plug-in connection, but the plug-in surface is not circular. The driving column 4 drives the reciprocating screw rod 9 to rotate, thereby causing the internal spray assembly to rotate inside the part.

[0026] The side wall of the central block 8 is fixedly connected with a guide rod 10, which is parallel to the reciprocating screw rod 9. The side wall of the reciprocating screw rod 9 is threadedly connected with an internal spray gun 11, which is slidably connected to the guide rod 10. The driving rod 12 is fixedly connected to the side wall of the driving column 4, and the side walls of the bracket 2 and the bracket 5 are fixedly connected with a slide groove 6.

[0027] like Figure 1-Figure 3 As shown, when the reciprocating screw 9 rotates, the inner spray gun 11 slides with the guide rod 10, and the guide rod is fixed, and the inner spray gun 11 moves with the rotation of the reciprocating screw 9, so that the inner spray gun 11 moves along a fixed trajectory inside the part to fully spray the inner wall of the part, and the slide groove 6 limits the running trajectory of the external spray assembly.

[0028] The external spraying assembly includes two groups of sliders 13, which are respectively slidably connected to the two groups of slide grooves 6. A reciprocating screw rod 14 is rotatably connected between the two groups of sliders 13. The reciprocating screw rod 14 passes through the end of the driving rod 12. A guide rod 15 is fixedly connected between the driving rod 12 and the sliders 13. An external spray gun 16 is threadedly connected to the side wall of the reciprocating screw rod 14, and the external spray gun 16 is slidably connected to the guide rod 15.

[0029] like Figure 1-Figure 3 As shown, when the inner spraying assembly rotates, the driving rod 12 drives the reciprocating screw rod 14 to move in a circular trajectory. The two ends of the reciprocating screw rod 14 are slidably connected to the slide groove 6 through the slider 13, so that the reciprocating screw rod 14 can maintain balance. The guide rod 15 is fixed and cannot rotate. It cooperates with the rotation of the reciprocating screw rod 14 to drive the outer spray gun 16 to move, so that the outer spray gun 16 surrounds the outer wall of the part in a threaded trajectory, and the outer wall of the part is sprayed evenly. The inner spray gun 11 and the outer spray gun 16 in this spray machine are connected to the pressure equipment and the external material box through a connecting pipe. The movement of the two groups of spray guns will not cause the connecting pipe to be entangled. This technology is a prior art and will not be described in detail.

[0030] The side wall of the driving rod 12 is fixedly connected with a servo motor 18, the output end of the servo motor 18 is fixedly connected with a driving gear 19, the side wall of the reciprocating screw rod 14 is fixedly connected with a fixed gear 17, and the driving gear 19 is meshed with the fixed gear 17 for transmission.

[0031] like Figure 1-Figure 3 As shown, the servo motor 18 drives the driving gear 19 to rotate, so that the fixed gear 17 drives the reciprocating screw rod 14 to rotate.

[0032] The base assembly includes two groups of fixing seats 1, bracket 1 2 and bracket 2 5 are respectively fixed to the upper ends of the two groups of fixing seats 1, two groups of connecting seats 20 are clamped between the two groups of fixing seats 1, and a collecting tank 22 is clamped between the two groups of connecting seats 20.

[0033] like Figure 1-Figure 3 As shown, the bracket 1 2 and the bracket 2 5 are connected and fixed via two sets of connecting seats 20. After the parts are installed, the bracket 1 2 and the bracket 2 5 are installed and fixed, and the collecting groove 22 collects the dripping paint.

[0034] The working principle of a fully automatic CNC spraying machine provided by the utility model is as follows:

[0035] The parts are installed by installing the cylinder 7, and the bracket 1 2 and the bracket 2 5 are fixed to control the rotation of the inner spraying assembly. The servo motor 1 3 drives the inner spraying assembly to rotationally spray the inner wall of the part. While the inner spraying assembly rotates, the outer spraying assembly is pulled to rotate in a circular arc trajectory through the driving rod 12, so that the outer spraying assembly sprays around the outer wall of the part, so that the inner and outer walls of the part are sprayed evenly at the same time, and the parts are sprayed automatically with high spraying efficiency.

[0036] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, and these changes and improvements fall within the scope of the utility model to be protected.
