[0036] In the embodiment, the screw displacement assembly specifically comprises: two screw rod seats 2 fixedly connected to the two side edge positions on the top end surface of the machine table 1, a transmission screw rod 3 rotatably connected between the two screw rod seats 2, second optical shafts 6 fixedly connected to the two sides of the transmission screw rod 3, a motor support plate 4 fixedly connected to the top end of one side surface of the machine table 1, a transmission motor 5 fixedly connected to one side surface of the motor support plate 4, an output shaft of the transmission motor 5 penetrating through the motor support plate 4 and fixedly connected with the transmission screw rod 3, a moving seat 36 threadedly connected to the transmission screw rod 3, the moving seat 36 fixedly connected to the fixed plate 8 at the top end, two parallel linear bearings 7 movably sleeved outside the second optical shafts 6, the linear bearings 7 fixedly connected with the fixed plate 8, and an inclination adjustment mechanism provided between the fixed plate 8 and the movable plate 9. The screw displacement assembly can quickly complete the transfer of the electromagnetic valve shell.

[0037] In the embodiment, the inclination adjustment mechanism specifically comprises: electromagnets 10 embedded in the top end surface of the fixed plate 8 at the four corner positions, metal sheets 11 embedded in the bottom end surface of the movable plate 9 at positions corresponding to the electromagnets 10, a telescopic motor 12 embedded in one side of the bottom end surface of the fixed plate 8, and an output shaft of the telescopic motor 12 in contact with the movable plate 9 at the top.

[0038] In the embodiment, a circular hole 14 is formed in the inside of the four-jaw chuck 13, and a notch 15 is formed in the bottom end of the outside surface of the four-jaw chuck 13 and communicates with the circular hole 14, and the opening direction of the notch 15 is away from the transmission motor 5. This setting can guide the polishing debris falling into the circular hole 14 out of the machine table 1 along the notch 15, which is convenient to use.

[0039] In the embodiment, the maximum included angle between the movable plate 9 and the fixed plate 8 is 3°.

[0040] The working principle of the present application is: in use, first, the electromagnetic valve shell to be polished is placed on the four-jaw chuck 13, and the jaws of the four-jaw chuck 13 clamp the outer wall of the electromagnetic valve shell. Then, the electromagnetic valve shell is transferred to the lower side of the polishing roller mechanism through the screw displacement assembly, specifically: the transmission motor 5 drives the transmission screw 3 to rotate, and the moving seat 36 moves forward along the transmission screw 3, and in the process, the fixed plate 8, the movable plate 9, the four-jaw chuck 13 and the electromagnetic valve shell follow the movement, while the cooperation of the linear bearing 7 and the second optical shaft 6 can improve the stability of the movement. When the electromagnetic valve shell is transferred to the lower side of the polishing roller mechanism, the polishing assembly operates to extend the polishing roller mechanism into the electromagnetic valve shell, specifically: the drive motor 19 drives the telescopic screw 18 to rotate, and the lifting plate 21 slowly moves downward along the telescopic screw 18, thereby driving the motor support seat 22, the polishing motor 23 and the polishing roller mechanism to descend synchronously, wherein the first optical shaft 20 can improve the stability of the lifting. After the polishing roller mechanism is extended into the electromagnetic valve shell, the polishing motor 23 drives the polishing roller mechanism to rotate to polish the inner wall of the electromagnetic valve shell. It should be noted that the polishing roller mechanism can accurately adjust the length of the polishing strip 31 extending out of the telescopic groove 30 as needed, thereby adapting to electromagnetic valve shells of different inner diameters, specifically: by turning the handle 28 in the circular groove 26, the two-way threaded rod 27 rotates, and the two square pyramids 29 on the two-way threaded rod 27 move away from each other under the limitation of the surrounding connecting plate 33, in the process, the connecting plate 33 and the square pyramids 29 have an inclined surface effect, causing the connecting plate 33 to move outward along the rectangular groove 32, thereby causing the polishing strip 31 to extend out of the telescopic groove 30 to adapt to electromagnetic valve shells of different inner diameters. In addition, through the setting of the anti-disengagement groove 37 and the anti-disengagement strip 38, they also displace relative to each other when the inclined surface effect occurs, which can prevent the connecting plate 33 and the square pyramids 29 from separating, ensuring the controllability of the adjustment of the polishing roller mechanism.

[0041] After the inner wall of the electromagnetic valve shell is polished, the screw displacement assembly operates to transfer the electromagnetic valve shell to the lower side of the camera 35, and then the movable plate 9 is adjusted to an inclined state through the inclination adjusting mechanism, specifically: the electromagnet 10 is de-energized and the magnetic connection with the metal sheet 11 is disconnected, the telescopic motor 12 operates to extend the output shaft to lift the movable plate 9, so that the included angle between the movable plate 9 and the fixed plate 8 is 3°. The electromagnetic valve shell inclines with the movable plate 9, so that the camera 35 can better capture part of the inner wall image of the electromagnetic valve shell, and send the image to the external background control terminal for image recognition analysis to determine whether the polishing effect is qualified. At the same time, the slag generated during polishing falls into the circular hole 14 of the four-jaw chuck 13, and the polishing debris is guided out of the machine table 1 along the gap 15, without the need for additional cleaning by the staff, which is convenient to use.

[0042] It will be apparent to those skilled in the art that various modifications and variations can be made to the present application without departing from the spirit or scope of the application. Thus, it is intended that the present application cover modifications and variations of this application provided they come within the scope of the appended claims and their equivalents.

[0043] The above description is only the preferred embodiment of the present application, but the protection scope of the present application is not limited to this. Any skilled person in the art can make equivalent substitutions or changes according to the technical scheme and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered in the protection scope of the present application.
