Detailed Embodiment

[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the protection scope of the present utility model.

[0021] Such as Figure 1 and Figure 2As shown in the figure, an engine fuel injector turning device includes a base 1. A turning groove 2 is provided on the base 1. A robotic arm 3 and a material fixture 4 are arranged in the turning groove 2. A blower 5 and a tool post 6 are arranged on the robotic arm 3. A turning tool 7 is arranged in the tool post 6. A fixing groove 8 is provided on the turning tool 7. A fixing screw 9 is arranged in the fixing groove 8. A water tank 10 is arranged on one side of the bottom of the turning groove 2.

[0022] As Figure 3 and Figure 4 shown, in another embodiment of the present invention, the fixing screw 9 includes a screw body 901. A screw head 902 is fixedly arranged at one end of the screw body 901. A through groove 903 is provided on the screw body 901.

[0023] A screwdriver slot 904 is provided on the screw head 902. A spring 905 is fixedly arranged in the screwdriver slot 904. A baffle 906 is fixedly arranged at one end of the spring 905. A sealing layer 907 is provided on the baffle 906. When turning the engine fuel injector, the baffle 906 is used to block the chips generated by turning, preventing the chips generated by turning from entering the screwdriver slot 904 and blocking the screwdriver slot 904. When it is necessary to replace the turning tool 7, first, a disassembly tool is used to squeeze the baffle 906 to make the baffle 906 move towards the screw body 901, deforming the spring 905. Then, the disassembly tool enters the screwdriver slot 904 and drives the screw head 902 to rotate through the screwdriver slot 904. The screw head 902 drives the screw body 901 to rotate, so that the whole fixing screw 9 leaves the fixing groove 8, releasing the fixation of the turning tool 7, thereby replacing the turning tool 7. After the replacement is completed, the whole fixing screw 9 enters the fixing groove 8 again to fix the turning tool 7. Then, the disassembly tool leaves the screwdriver slot 904, and the spring 905 rebounds to make the baffle 906 return to its original position, thereby reusing the baffle 906 to block the chips generated by turning.

[0024] The working principle of the engine fuel injector turning device:

[0025] In use, first place the workpiece on the workpiece fixture 4, then use the workpiece fixture 4 to fix the workpiece. Subsequently, rotate the workpiece, and then use the robotic arm 3 to move the turning tool 7 towards the workpiece for turning. Then start the blower 5 and use the blower 5 to blow air at the turning tool 7. Most of the workpiece near the turning tool 7 is blown towards the water tank 10 by the blower 5, and the water tank 10 is used to collect the workpiece. Subsequently, use the baffle 906 to block the remaining debris generated by turning. When it is necessary to replace the turning tool 7, first use the disassembly tool to squeeze the baffle 906, causing the baffle 906 to move towards the screw body 901, deforming the spring 905. Then the disassembly tool enters the screwdriver slot 904 and drives the screw head 902 to rotate through the screwdriver slot 904. The screw head 902 drives the screw body 901 to rotate, causing the fixing screw 9 as a whole to leave the fixing slot 8, releasing the fixation of the turning tool 7, so as to replace the turning tool 7. After the replacement is completed, again insert the fixing screw 9 as a whole into the fixing slot 8 to fix the turning tool 7. Then make the disassembly tool leave the screwdriver slot 904, and the spring 905 rebounds, causing the baffle 906 to return to its original position, thereby reusing the baffle 906 to block the debris generated by turning, which can effectively prevent the debris generated by turning from entering the screwdriver slot 904 and blocking the screwdriver slot 904.

[0026] Obviously, the above embodiments of the present utility model are merely examples for clearly illustrating the present invention, rather than limitations on the implementation modes of the present invention. For those of ordinary skill in the art, other different forms of changes or variations can be made based on the above description. It is impossible to list all the implementation modes here. Any obvious changes or variations derived from the technical solutions of the present invention still fall within the protection scope of the present invention.
