It is a high-precision, high-efficiency automatic processing equipment developed on the basis of a traditional milling machine by combining microelectronics and computer technology.

The device makes the power assembly 103 slide along the connecting plate 102 and bring the tool 104 to the workpiece. When the power assembly 103 moves, the pull rope 105 will also slide along the support seat 1. When the pull rope 105 moves, the pulley 112 will rotate under the action of friction. At this time, the tension of the orifice plate 111 by the pull rope 105 will be weakened and it will move under the elastic force of the spring telescopic rod 110. When the orifice plate 111 moves, it will approach the power assembly 103 until the orifice plate 111 and the power assembly 103 come into contact. At this time, the fixed assembly 108 and the workpiece are located at the orifice plate 111. Inside, the tool 104 will come into contact with the workpiece and process the workpiece, and the debris generated during the workpiece processing will splash and reach the orifice plate 111, and the orifice plate 111 will intercept the splashing debris to reduce the range of the debris splashing; when the power component 103 moves toward the workpiece, the orifice plate 111 will approach the power component 103 under the elastic force of the spring telescopic rod 110 and close the workpiece, so that the debris splashed when the workpiece is processed by the tool 104 will be intercepted by the orifice plate 111, thereby realizing the device's control over the debris splashing range and reducing the debris remaining on the surface of the device.

[0029] See also Figure 2 and Figure 5 As shown, a plurality of protrusions 3 are fixedly connected to the top of the second top plate 23; a plurality of fixing grooves 32 are provided at the bottom of the power assembly 103; the fixing grooves 32 and the protrusions 3 are correspondingly arranged and are slidably matched; when the second top plate 23 moves, it will move with the protrusions 3, and when the second top plate 23 and the power assembly 103 come into contact, the protrusions 3 will enter the interior of the fixing grooves 32, thereby increasing the contact area between the second top plate 23 and the power assembly 103, and when the tool 104 grinds the workpiece, vibration will be generated, and the vibration will be transmitted to the second top plate 23 by the power assembly 103, causing the second top plate 23 to shake, and the second top plate 23 will reduce the amplitude of the shaking under the friction between the protrusions 3 and the fixing grooves 32, thereby improving the stability of the orifice plate 111 during operation.
[0030] See also Figure 5 As shown, a rubber ring 4 is fixedly connected to the middle of the protrusion 3; the rubber ring 4 is located between the second top plate 23 and the power assembly 103; when the protrusion 3 and the fixing groove 32 come into contact, the rubber ring 4 will also come into contact with the fixing groove 32. Because the surface friction coefficient of the rubber ring 4 is larger, the rubber ring 4 will increase the friction between the protrusion 3 and the fixing groove 32, further improving the stability of the second top plate 23 and the orifice plate 111 during operation.
[0031] See also Figure 4 and Figure 6As shown, the middle part of the column 107 is rotatably connected to a plurality of connecting rings 5; the middle part of the connecting ring 5 is fixedly connected to a plurality of bristles 52; when the orifice plate 111 moves toward the power assembly 103, the orifice plate 111 will come into contact with the bristles 52, and when the bristles 52 come into contact with the orifice plate 111, the holes on the surface of the orifice plate 111 will be dredged, thereby reducing the debris remaining on the surface of the orifice plate 111, improving the convenience of the device for cleaning the orifice plate 111, and extending the service life of the orifice plate 111.
[0032] See also Figure 4 and Figure 6 As shown, a cross bar 6 is fixedly connected to the middle part of the connecting ring 5; a slide plate 62 is fixedly connected to the inner side wall of the orifice plate 111; the slide plate 62 is a spiral structure; when the orifice plate 111 moves, it will move with the slide plate 62, and when the slide plate 62 moves, it will contact the cross bar 6 and make the cross bar 6 slide along the surface of the slide plate 62. Because the slide plate 62 is a spiral structure, the connecting ring 5 will rotate under the friction between the cross bar 6 and the slide plate 62, and when the connecting ring 5 rotates, it will rotate with the bristles 52, and when the bristles 52 rotate, the contact area with the surface of the orifice plate 111 will be increased, thereby enhancing the cleaning effect of the bristles 52 on the surface of the orifice plate 111.
[0033] See also Figure 6 As shown, a plurality of ball bearings 7 are rotatably connected to the middle portion of the crossbar 6; the ball bearings 7 are arranged in an array; when the crossbar 6 and the slide plate 62 come into contact, the ball bearings 7 will also come into contact with the slide plate 62, and the ball bearings 7 will roll under the action of friction, so that the sliding friction between the crossbar 6 and the slide plate 62 is converted into rolling friction, thereby reducing the friction between the crossbar 6 and the slide plate 62, and reducing the scratches and damage on the surface of the slide plate 62 caused by friction.
[0034] Working principle: After placing the workpiece on the top of the fixing component 108, the workpiece will be fixed by the fixing component 108, and then the device is started to make the power component 103 slide along the connecting plate 102 and bring the tool 104 to the workpiece. When the power component 103 moves, the pull rope 105 will also slide along the support seat 1. When the pull rope 105 moves, the pulley 112 will rotate under the action of friction. At this time, the tension of the orifice plate 111 by the pull rope 105 will be weakened and move under the elastic force of the spring telescopic rod 110. When the orifice plate 111 moves, it will approach the power component 103 until the orifice plate 111 and the power component 103 come into contact. At this time, the fixing component 108 and the workpiece are located inside the orifice plate 111, and the tool 1 04 will come into contact with the workpiece and process the workpiece, and the debris generated during the workpiece processing will splash and reach the orifice plate 111, and the orifice plate 111 will intercept the splashing debris to reduce the range of the debris splashing; when the orifice plate 111 moves, it will move with the first top plate 2 and the damping spring 22, and the damping spring 22 will move with the second top plate 23 toward the power assembly 103 until the second top plate 23 and the power assembly 103 come into contact. When the second top plate 23 and the power assembly 103 come into contact, they will be impacted and transfer the impact to the damping spring 22. After absorbing the impact energy, the damping spring 22 will be compressed and transfer the attenuated energy to the first top plate 2 and the orifice plate 111, reducing the orifice plate 11 1 is subjected to the impact; when the second top plate 23 moves, it will move with the protrusion 3. When the second top plate 23 and the power assembly 103 come into contact, the protrusion 3 will enter the interior of the fixing groove 32, increasing the contact area between the second top plate 23 and the power assembly 103. When the tool 104 grinds the workpiece, it will generate vibration, which will be transmitted to the second top plate 23 by the power assembly 103 and cause the second top plate 23 to shake. The second top plate 23 will reduce the amplitude of the shaking under the friction between the protrusion 3 and the fixing groove 32. When the protrusion 3 and the fixing groove 32 come into contact, the rubber ring 4 will also come into contact with the fixing groove 32. Because the surface friction coefficient of the rubber ring 4 is larger, the rubber ring 4 will increase the friction between the protrusion 3 and the fixing groove 32. When the orifice plate 111 moves toward the power assembly 103, the orifice plate 111 will come into contact with the bristles 52. When the bristles 52 come into contact with the orifice plate 111, the holes on the surface of the orifice plate 111 will be dredged, thereby reducing the debris remaining on the surface of the orifice plate 111 and improving the convenience of the device for cleaning the orifice plate 111. When the orifice plate 111 moves, it will move with the slide plate 62. When the slide plate 62 moves, it will come into contact with the cross bar 6 and make the cross bar 6 slide along the surface of the slide plate 62. Because the slide plate 62 is a spiral structure, the connecting ring 5 will rotate under the friction between the cross bar 6 and the slide plate 62. When the connecting ring 5 rotates, it will rotate with the bristles 52. When the bristles 52 rotate, the contact area with the surface of the orifice plate 111 will increase.When the crossbar 6 and the slide plate 62 come into contact, the ball 7 will also come into contact with the slide plate 62, and the ball 7 will roll under the friction, so that the sliding friction between the crossbar 6 and the slide plate 62 is converted into rolling friction, reducing the friction between the crossbar 6 and the slide plate 62. ;

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.
