[0063] It should be noted that the features in the embodiments of the present application can be combined with each other without conflict.

[0064] It should be understood that due to the inconsistency of the thickness of the workpiece, after clamping or fixing the workpiece, if the workpiece is thin, the fixing structure may exceed the thickness of the workpiece, so that the flattening wheel 42 collides with the fixing structure when machining the workpiece, and the flattening wheel 42 or the fixing structure is damaged.

[0065] In addition, the position of the fixing structure acting on the workpiece is higher or lower, which makes the clamping of the workpiece by the fixing structure unstable, and finally leads to poor effect of the flattening machining of the workpiece.

[0066] In order to improve the above problems, the embodiment provides a flattening machining device for machining piece 300, mainly including first platform 1 and second platform 7. The device is mainly used for flattening machining of the workpiece while fixing the workpiece stably, and will not collide with the flattening wheel 42.

The two tightening screws 32 are arranged at the centers of the two vertical plates 31, and are threadedly connected to the two vertical plates 31. Specifically, one end of the tightening screw 32 is provided with a tightening plate 34. When the tightening screw 32 is screwed, the one end of the tightening screw 32 moves towards the workpiece on the upper surface of the clamping platform 2, thereby driving the side wall of the tightening plate 34 to abut and fit with the side wall of the workpiece, so as to fix the workpiece 300.

[0071] The first platform 1 is provided with a hole matched with the slide rod 33, so that the slide rod 33 can slide up and down in the vertical direction, thereby driving the vertical plate 31 to move up and down.

[0072] In this embodiment, as shown in the figure, Figures 1-4 The upper side of the clamping platform 2 is provided with a flattening member 4 for processing the flatness of the workpiece 300.

A rotating motor 70 is provided on the outer wall of one of the protrusions 41. One end of the displacement rod 60 is rotatably connected to one of the protrusions 41, and the other end of the displacement rod 60 passes through the other protrusion 41 and is connected to the rotating motor 70, so that the rotating motor 70 drives the displacement rod 60 to rotate. The rotating motor 70 can rotate forward and reverse.

[0076] The tightening screw 32 is fitted with a displacement block 80, which is threadedly connected to the displacement rod 60.

The connecting shaft 41 is perpendicular to the displacement rod 60, so that the drive motor 90 drives the connecting shaft 41 to rotate. At the same time, the two displacement rods 60 rotate, which in turn drives the connecting shaft 41 and the two displacement blocks 80 to move. The lifting column 50 drives the lifting plate 40 to rise or fall, so that the displacement of the leveling wheel 42 can be adjusted according to the size of the workpiece 300, and the surface of the workpiece 300 can be processed.

[0077] The rising column 50 can be constructed using a hydraulic cylinder, an electric push rod, or a telescopic rod.

The axial direction of the rotating shaft 6 is parallel to the opposite side walls of the two vertical plates 31, and the lifting screw 9 is perpendicular to the opposite side walls of the two vertical plates 31.

[0079] In this embodiment, as Figures 1-3As shown, the second platform 7 is arranged below the first platform 1, wherein the second platform 7 can adopt a rectangular body, a cylindrical body or the like structure, in this embodiment, the second platform 7 adopts a rectangular body structure, specifically, the first platform 1 and the second platform 7 are arranged in parallel, and four support columns 30 are arranged between the lower surface of the first platform 1 and the upper surface of the second platform 7, thereby leaving a space for the remaining structure of the second platform 7, wherein when the vertical plate 31 is not raised, the lower surface of the vertical plate 31 is attached to the upper surface of the first platform 1, and the lower surfaces of the three rollers 61 and the two convex plates 51 are all in abutment with the upper surface of the second platform 7.

[0080] As shown in Figure 1 and Figure 5 , the upper surface of the second platform 7 is provided with two oppositely arranged vertical plates 8, specifically, the two vertical plates 8 are oppositely arranged on both sides of the rotating shaft 6 and are symmetrical with respect to the rotating shaft 6, wherein the two vertical plates 8 both adopt a rectangular body structure, and the four side walls of the circumferential direction of the two vertical plates 8 are respectively parallel to the four side walls of the circumferential direction of the first platform 1.

[0081] Among them, the center of the two vertical plates 8 is provided with a jacking screw 9, the jacking screw 9 is threadedly connected with the vertical plate 8, the jacking screw 9 is axially parallel to the upper surface of the second platform 7, and the jacking screw 9 is perpendicular to the side wall of the vertical plate 8 facing the rotating shaft 6.

[0082] Among them, as shown in Figures 1-6 , the opposite ends of the two jacking screws 9 are both provided with a jacking plate 10, the jacking plate 10 adopts a rectangular body structure, and the two opposite side walls of the jacking plate 10 are respectively parallel to the two opposite side walls of the two vertical plates 8, in this embodiment, the jacking screw 9 and the jacking plate 10 are rotatably connected, so that the jacking screw 9 drives the jacking plate 10 to displace along the axial direction of the jacking screw 9, specifically, the side wall of the jacking plate 10 facing the vertical plate 8 is provided with a rotating bearing 200, and one end of the jacking screw 9 is connected with the rotating bearing 200.

[0083] In this embodiment, as shown in Figures 5-11 , one of the jacking plates 10 is provided with two right-angle blocks 101 on the side wall away from the jacking screw 9, and the other jacking plate 10 is provided with one right-angle block 101 on the side wall away from the jacking screw 9, and the inclined surface of the right-angle block 101 faces between the other two right-angle blocks 101, specifically, the three right-angle blocks 101 are arranged at intervals along the axial direction of the rotating shaft 6, wherein the two jacking plates 10 are oppositely arranged on both sides of the three rollers 61, and the three rollers 61 are arranged on one side of the three right-angle blocks 101.

[0084] In this embodiment, as shown in Figures 5-7As shown, the upper surface of the second platform 7 is provided with three sliding grooves 71, which are axially arranged along the jacking screw 9. The lower end surface of the three right-angle blocks 101 is provided with sliding blocks 102. The sliding blocks 102 on the lower side of the three right-angle blocks 101 are respectively matched with the three sliding grooves 71 and are respectively arranged in the three sliding grooves 71, so that the jacking plate 10 and the right-angle blocks 101 are displaced along the three sliding grooves 71.

[0085] In this embodiment, when the flatness processing of the workpiece 300 is performed, the workpiece 300 is first placed on the clamping platform 2, and then the position of the abutting plate 34 abutting against the workpiece 300 is determined according to the thickness of the workpiece 300, so that the abutting plate 34 stably abuts against the workpiece 300 without colliding with the flattening wheel 42. After the position of the abutting plate 34 is determined, one of the jacking screws 9 is screwed, so that the jacking screw 9 drives the jacking plate 10 and the right-angle blocks 101 to be displaced towards the rotating shaft 6 and the three rollers 61, so that the inclined surface of the right-angle block 101 of the jacking plate 10 abuts against the roller 61. The roller 61 slides along the inclined surface of the right-angle block 101 under the action of the right-angle block 101, so that the slide rod 33, the vertical plate 31 and the jacking screw 32 are displaced upwards. When the abutting plate 34 at one end of the jacking screw 32 is raised to the predetermined height, the screwing of the jacking screw 9 is stopped, and another jacking screw 9 is screwed, so that the three right-angle blocks 101 respectively abut against the three rollers 61, thereby stably supporting the rollers 61. Finally, the jacking screw 32 is screwed, so that the two abutting plates 34 abut against the workpiece 300, thereby fixing the workpiece 300. Finally, the lifting column 50 is lowered, so that the flattening wheel 42 abuts against the workpiece 300. Then, the driving motor 90 is driven to rotate, thereby driving the flattening wheel 42 to process the surface of the workpiece 300. At the same time, the rotating motor 70 drives the displacement rod 60 to rotate, so that the displacement block 80 drives the connecting shaft 41, the flattening wheel 42 and the driving motor 90 to be axially displaced along the jacking screw 32, thereby processing the surface of the workpiece 300.

[0086] The length of the three sliding grooves 71 is set according to the inclination of the inclined surface of the right-angle block 101 and the maximum size of the jacking screw 32 that needs to be raised and lowered.

[0087] In the embodiment, the outer edge of the upper surface of the second platform 7 is provided with a displacement scale 20, which is arranged axially along the jacking screw 9. Specifically, the displacement scale 20 is provided with a scale. The side walls of the two jacking plates 10 facing the displacement scale 20 are each provided with a marking piece 400, which is axially perpendicular to the displacement scale 20 and parallel to the first planar surface. Specifically, the marking piece 400 adopts an infrared emitter, and the infrared line emits infrared rays towards the displacement scale 20. When the jacking screw 9 is twisted to push the jacking plate 10 and the right-angle block 101, the jacking plate 10 drives the marking piece 400 to displace, and the displacement distance of the jacking plate 10 is known. Therefore, the displacement distance of the two jacking plates 10 and the right-angle block 101 is controllable, and the lifting distance of the vertical plate 31, the jacking screw 32 and the jacking plate 34 is controllable, thereby improving the adjustment efficiency.
