[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. In the present invention, the workpiece to be milled is placed on the positioning table, the hydraulic cylinder is started to drive the lifting plate to descend, the lifting plate drives the pressure plates on both sides to descend, the pressure plates squeeze the inclined blocks on both sides, push the inclined blocks to drive the connecting rod 1 to move in the direction of approaching each other on the bracket, compress the spring 1, the connecting rod 1 will also drive the clamping plates 1 on both sides to move synchronously close to each other, until the side of the pressure plate approaching each other contacts the side of the inclined block away from each other, the inclined block, the connecting rod 1 and the clamping plate 1 stop moving, at this time the side of the clamping plate 1 approaching each other just clamps and fixes the two ends of the workpiece, and when the clamping plate 1 moves close to each other, it will also drive the inclined panels, the connecting rod 2, the clamping plate 2 and the limit strip on both sides to move synchronously close to each other, and the inclined panels move When the lever is in motion, it will be blocked by the top bar, pushing the inclined plate to slide downward on the clamp plate 1, compressing the spring 4, and the inclined plate will also drive the connecting rod 2 and the clamp plate 2 to descend synchronously. When the lower end of the clamp plate 2 contacts the upper end of the workpiece, as the inclined plate continues to descend, the inclined plate will slide downward on the connecting rod 2, compressing the spring 3, until the lower end of the limit bar contacts and stops with the upper end of the connecting rod 2. The provided clamp plate 1 is convenient for clamping and fixing the left and right ends of the workpiece, and the clamp plate 2 is convenient for clamping and fixing the left and right ends of the workpiece with a pair of clamp plates, providing a clamping and fixing force on the left and right sides of the upper end of the workpiece, so that the clamp plate 1 and the clamp plate 2 cooperate with each other, which can have a good clamping effect on the workpiece, thereby ensuring the subsequent milling work of the workpiece.

[0017] 2. In the present invention, the limit strip is provided to limit the second connecting rod and the second clamping plate, thereby improving the clamping firmness of the second clamping plate.

[0018] 3. In the present invention, when the clamping plates 1 on both sides approach each other to clamp the workpiece, the magnetic movable plates on both sides will also be driven to move synchronously. When the magnetic movable plates move to the back side of the magnetic frame, a magnetic repulsive force will be generated on the magnetic movable plates, pushing the magnetic movable plates to slide backward on the clamping plate 1, compressing the spring 2. The magnetic movable plates will also drive the rotating shaft and the flexible cleaning roller to move backward synchronously. The flexible cleaning roller will remove the debris adhered to the two ends of the workpiece to be clamped and the end of the clamping plate 1 that is close to each other, avoiding the formation of a gap between the clamping plate 1 and the workpiece due to the adhered debris, thereby ensuring the stability of the clamping of the clamping plate 1 on the workpiece.

[0019] 4. In the present invention, under the action of torsion spring 1 and wire rope, the torsion spring 1 releases pressure, which drives the rotating shaft and the flexible cleaning roller to rotate on the magnetic movable plate, and the wire rope is automatically wound on the upper side of the rotating shaft to remove the firmly adhered debris, thereby improving the cleaning quality of the flexible cleaning roller on the clamping surface of the workpiece and the side close to the clamping plate 1.

[0020] 5. In the present invention, when the magnetic movable plate moves backward, it will also drive the flexible cleaning block to move synchronously. The flexible cleaning block is arranged to facilitate the flexible cleaning roller to remove the debris dropped on the positioning table and sweep it to the rear side, thereby avoiding the debris dropped from being removed and remaining between the clamping plate 1 and the workpiece, and preventing the gap from still appearing when the clamping plate 1 and the workpiece are clamped, resulting in unstable clamping, thereby improving the clamping stability of the clamping plate 1 on the workpiece.

[0021] 6. In the present invention, when the magnetic movable plate moves backward, it will also drive the rotating rod, the elastic bar and the magnetic baffle rod to move backward synchronously. When the magnetic baffle rod moves to the side where the magnetic blocks are away from each other, the magnetic block generates a magnetic repulsive force on the magnetic baffle rod, pushing the magnetic baffle rod to slide on the magnetic movable plate in a direction away from each other, and the magnetic baffle rod is separated from the upper side of the elastic bar. The elastic bar and the rotating rod rotate backward under the action of the torsion spring 2. At this time, the flexible cleaning roller and the flexible cleaning block have moved to the rear side of the splint 1, and the lower end of the elastic bar will collide with the flexible cleaning block, causing the flexible cleaning block to deform, which is conducive to the flexible cleaning block to bounce the debris swept to the rear side of the splint 1 to the outside of the positioning table, thereby avoiding the debris remaining on the positioning table and affecting the subsequent workpiece clamping, ensuring the cleanliness of the positioning table, thereby ensuring the subsequent milling quality of the workpiece.

[0022] 7. In the present invention, when the rotating shaft rotates backward, it will squeeze the arc surface at the lower end of the arc panel, push the arc panel to slide upward on the lower end of the inclined panel, compress the spring five and the airbag, and make the gas in the airbag spray out from the jet pipe. The sprayed gas is conducive to blowing the debris in the clamping area between the lower end of the second clamping plate and the workpiece to a distance, avoiding the occurrence of gaps when the second clamping plate and the upper end of the workpiece are clamped, resulting in unstable clamping, thereby also ensuring the subsequent milling quality of the workpiece.

The lifting plate 4 drives the pressure plates 10 on both sides to descend. The pressure plates 10 squeeze the inclined blocks 8 on both sides, pushing the inclined blocks 8 to drive the connecting rod 17 to move in the direction of approaching each other on the bracket 2, compressing the spring 19, and the connecting rod 17 will also drive the clamping plates 6 on both sides to move synchronously toward each other, until the side of the pressing plate 10 that is close to each other contacts the side of the inclined block 8 that is away from each other, the inclined block 8, the connecting rod 17 and the clamping plate 16 stop moving.

The set clamping plate 1 6 is convenient for clamping and fixing the left and right ends of the workpiece. The clamping plate 24 is convenient for clamping and fixing the left and right ends of the workpiece when the clamping plate 1 6 clamps and fixes the left and right ends of the workpiece, providing a clamping and fixing force on the left and right sides of the upper end of the workpiece, so that the clamping plate 1 6 and the clamping plate 2 24 cooperate with each other, which can play a good clamping effect on the workpiece and ensure the subsequent milling work of the workpiece.

After the workpiece is clamped and fixed, the milling device 5 is started to mill the workpiece.

[0027] As an embodiment of the present invention, a stabilizing mechanism is further provided for enabling the clamping plate 1 6 and the clamping plate 2 24 to firmly clamp the workpiece, the stabilizing mechanism comprising a magnetic movable plate 11 slidably mounted on the front side of the upper end of the clamping plate 1 6, and magnetic frames 1101 are fixedly mounted on the corresponding magnetic movable plates 11 on the left and right ends of the inner side of the bracket 2, the magnetic frame 1101 is located on the front side of the magnetic movable plate 11, a spring 2 12 is fixedly mounted on the rear end of the magnetic movable plate 11, a connecting plate 13 is fixedly mounted on the rear end of the spring 2 12, the lower end of the connecting plate 13 is fixedly mounted on the clamping plate 1 6, a rotating shaft 14 is rotatably mounted through the rear end of the magnetic movable plate 11, a flexible cleaning roller 15 is fixedly mounted on the lower end of the rotating shaft 14, a torsion spring 16 is sleeved on the outer side of the rotating shaft 14, a steel wire rope 17 is fixedly wound on the upper side of the rotating shaft 14, the rear end of the steel wire rope 17 is fixedly connected to the connecting plate 13, the lower end of the magnetic movable plate 11 is located at the front side of the flexible cleaning roller 15 A flexible cleaning block 18 is fixedly installed, and an elastic strip 19 is provided on the front side of the flexible cleaning block 18. A rotating rod 20 is fixedly installed on the upper side of the middle part of the elastic strip 19. The ends of the rotating rods 20 close to each other are rotatably connected with the magnetic movable plate 11. A torsion spring 21 is sleeved on the outer side of the rotating rod 20. A magnetic baffle 22 is abutted and fitted on the upper side of the front end of the elastic strip 19. The magnetic baffle 22 is slidably installed on the front end of the magnetic movable plate 11, and a magnetic block 23 is fixedly installed on the lower side of the front end of the connecting plate 13 corresponding to the magnetic baffle 22. A jet pipe 31 is provided on the side of the two splints 24 that are away from each other. An air bag 32 is connected to the upper end of the jet pipe 31. The upper end of the air bag 32 is fixedly installed on the inclined plate 26. The lower end of the air bag 32 is fixedly installed with an arc panel 33.

The upper end of the arc panel 33 is symmetrically fixed with springs 5 ​​34, and the upper end of the spring 5 34 is fixedly installed on the inclined plate 26. During operation, when the clamping plates 6 on both sides approach each other to clamp the workpiece, the magnetic movable plates 11 on both sides will also be driven to move synchronously. When the magnetic movable plates 11 move to the rear side of the magnetic frame 1101, a magnetic repulsive force will be generated on the magnetic movable plates 11, pushing the magnetic movable plates 11 to slide backward on the clamping plates 6, compressing the spring 12. The magnetic movable plates 11 will also drive the rotating shaft 14 and the flexible cleaning roller 15 to move backward synchronously. The flexible cleaning roller 15 will remove the debris adhered to the two ends of the workpiece to be clamped and the end of the clamping plates 6 that are close to each other, avoiding the formation of a gap between the clamping plates 6 and the workpiece due to the adhered debris, thereby ensuring the stability of the clamping of the workpiece by the clamping plates 6. Under the action of the torsion spring 16, the pressure is released, which will drive the rotating shaft 14 and the flexible cleaning roller 15 to rotate on the magnetic movable plate 11, and the wire rope 17 is automatically wound on the upper side of the rotating shaft 14 to remove the debris that is more firmly adhered, thereby improving the cleaning quality of the flexible cleaning roller 15 on the side where the workpiece to be clamped and the clamping plate 6 are close to each other. When the magnetic movable plate 11 moves backward, it will also drive the flexible cleaning block 18 to move synchronously. The set flexible cleaning block 18 is convenient for the flexible cleaning roller 15 to clean the debris dropped on the positioning table 1 to the rear side, thereby avoiding the residue of the dropped debris between the clamping plate 6 and the workpiece, and the gap between the clamping plate 6 and the workpiece still appears when the clamping plate 6 is clamped, resulting in unstable clamping, thereby improving the clamping plate 6. Regarding the clamping stability of the workpiece, when the magnetic movable plate 11 moves backward, it will also drive the rotating rod 20, the spring bar 19 and the magnetic blocking rod 22 to move backward synchronously. When the magnetic blocking rod 22 moves to the side where the magnetic block 23 moves away from each other, the magnetic block 23 generates a magnetic repulsive force on the magnetic blocking rod 22, pushing the magnetic blocking rod 22 to slide on the magnetic movable plate 11 in a direction away from each other, and the magnetic blocking rod 22 separates from the upper side of the spring bar 19. The spring bar 19 and the rotating rod 20 rotate backward under the action of the torsion spring 21. At this time, the flexible cleaning roller 15 and the flexible cleaning block 18 have moved to the rear side of the splint 16, and the lower end of the spring bar 19 will hit the flexible cleaning block 18, causing the flexible cleaning block 18 to deform, which is beneficial for the flexible cleaning block 18 to The debris swept to the rear side of the clamping plate 6 is bounced to the outside of the positioning table 1, preventing the debris from remaining on the positioning table 1 and affecting the subsequent clamping of the workpiece, ensuring the cleanliness of the positioning table 1, thereby ensuring the subsequent milling quality of the workpiece; when the rotating shaft 14 rotates backward, it will squeeze the arc surface of the lower end of the arc panel 33, pushing the arc panel 33 to slide upward on the lower end of the inclined panel 26, compressing the spring five 34 and the airbag 32, so that the gas in the airbag 32 is ejected from the jet pipe 31, and the ejected gas is conducive to blowing the debris in the clamping area between the lower end of the clamping plate 24 and the workpiece to a distance, avoiding the occurrence of gaps when the clamping plate 24 and the upper end of the workpiece are clamped, resulting in unstable clamping, thereby also ensuring the subsequent milling quality of the workpiece.

[0028] Working principle: When the present invention is used, the workpiece to be milled is placed on the positioning table 1, and the hydraulic cylinder 3 is started to drive the lifting plate 4 to descend, and the lifting plate 4 drives the pressing plates 10 on both sides to descend, and the pressing plates 10 squeeze the inclined blocks 8 on both sides, pushing the inclined blocks 8 to drive the connecting rod 17 to move in the direction of approaching each other on the bracket 2, compressing the spring 19, and the connecting rod 17 will also drive the clamping plates 6 on both sides to move synchronously toward each other, until the side of the pressing plate 10 that is close to each other contacts the side of the inclined block 8 that is away from each other, and the inclined block 8, the connecting rod 17 and the clamping plate 6 stop moving. At this time, the side of the clamping plate 6 that is close to each other just clamps and fixes the two ends of the workpiece, and when the clamping plates 6 move toward each other, they will also drive the inclined panels 26, the connecting rod 25, the clamping plate 24 and the limit strip 30 on both sides to move synchronously toward each other. When the inclined plate 26 moves, it will be blocked by the top bar 28, pushing the inclined plate 26 to slide downward on the clamping plate 1 6, compressing the spring 4 29, and the inclined plate 26 will also drive the connecting rod 25 and the clamping plate 24 to descend synchronously. When the lower end of the clamping plate 24 contacts the upper end of the workpiece, as the inclined plate 26 continues to descend, the inclined plate 26 will slide downward on the connecting rod 25, compressing the spring 3 27, until the lower end of the limit bar 30 contacts the upper end of the connecting rod 25 and stops. The provided clamping plate 1 6 is convenient for clamping and fixing the left and right ends of the workpiece, and the clamping plate 24 is convenient for clamping and fixing the left and right ends of the workpiece by the clamping plate 1 6, providing a clamping and fixing force on the left and right sides of the upper end of the workpiece, so that the clamping plate 1 6 and the clamping plate 2 24 cooperate with each other, which can play a good clamping role on the workpiece. The limiting strip 30 is provided to limit the connecting rod 25 and the clamping plate 24, thereby improving the clamping firmness of the clamping plate 24. After the workpiece is clamped and fixed, the milling device 5 is started to perform milling on the workpiece. When the clamping plates 6 on both sides are close to each other to clamp the workpiece, the magnetic movable plates 11 on both sides are also driven to move synchronously. When the magnetic movable plates 11 move to the rear side of the magnetic frame 1101, a magnetic repulsive force is generated on the magnetic movable plates 11, pushing the magnetic movable plates 11 to slide backward on the clamping plates 6, compressing the spring 2 12. The magnetic movable plates 11 also drive the rotating shaft 14 and the flexible cleaning roller 15 to move backward synchronously. The provided flexible cleaning roller 15 can clamp the two ends of the workpiece to be clamped and the clamping plates 6 The debris adhered to the ends close to each other is removed, avoiding the appearance of a gap between the clamping plate 6 and the workpiece caused by the adhered debris, thereby ensuring the stability of the clamping plate 6 on the workpiece. Under the action of the torsion spring 16 and the wire rope 17, the torsion spring 16 releases the pressure, which will drive the rotating shaft 14 and the flexible cleaning roller 15 to rotate on the magnetic movable plate 11, and the wire rope 17 is automatically wound on the upper side of the rotating shaft 14 to remove the debris that is more firmly adhered, thereby improving the cleaning quality of the flexible cleaning roller 15 on the side of the workpiece to be clamped and the clamping plate 6 that is close to each other. When the magnetic movable plate 11 moves backward, it will also drive the flexible cleaning block 18 to move synchronously. The set flexible cleaning block 18 is convenient for the flexible cleaning roller 15 to remove the debris dropped on the positioning table 1 and sweep it to the rear side.This avoids the debris that has been cleared and remains between the clamping plate 6 and the workpiece. A gap still occurs when the clamping plate 6 and the workpiece are clamped, resulting in unstable clamping, thereby improving the clamping stability of the clamping plate 6 on the workpiece. When the magnetic movable plate 11 moves backward, it will also drive the rotating rod 20, the spring bar 19 and the magnetic blocking rod 22 to move backward synchronously. When the magnetic blocking rod 22 moves to the side where the magnetic block 23 is away from each other, the magnetic block 23 generates a magnetic repulsive force on the magnetic blocking rod 22, pushing the magnetic blocking rod 22 to slide on the magnetic movable plate 11 in a direction away from each other. The magnetic blocking rod 22 is separated from the upper side of the spring bar 19, and the spring bar 19 and the rotating rod 20 rotate backward under the action of the torsion spring 21. At this time, the flexible cleaning roller 15 and the flexible cleaning block 18 have moved to the rear side of the clamping plate 6, and the lower end of the spring bar 19 will press against the flexible cleaning block 18. The impact causes the flexible cleaning block 18 to deform, which is conducive to the flexible cleaning block 18 to bounce the debris swept to the rear side of the clamping plate 1 6 to the outside of the positioning table 1, avoiding the debris remaining on the positioning table 1 and affecting the subsequent workpiece clamping, ensuring the neatness of the positioning table 1, thereby ensuring the subsequent milling quality of the workpiece. When the rotating shaft 14 rotates backward, it will squeeze the arc surface of the lower end of the arc panel 33, pushing the arc panel 33 to slide upward on the lower end of the inclined panel 26, compressing the spring 5 34 and the airbag 32, so that the gas in the airbag 32 is ejected from the jet pipe 31. The ejected gas is conducive to blowing the debris in the clamping area between the lower end of the clamping plate 24 and the workpiece to a distance, avoiding the gap between the clamping plate 24 and the upper end of the workpiece, resulting in unstable clamping, thereby also ensuring the subsequent milling quality of the workpiece.
