[0033] like Figures 1 to 4 As shown, the utility model provides a pneumatic punching machine with a flip structure.

[0034] Specifically, by Figure 1-2 The invention provides a method of providing a rotating shaft 10 for rotating axles 1 and 2, and comprises: a base plate 1, a punching machine assembly 12 fixedly connected to the top surface of the base plate 1, a detachable bearing platform 13 slidably arranged on the top surface of the base plate 1, a flipping assembly arranged on the base plate 1, and the flipping assembly comprises a fixed plate 2, a bearing 3, a rotating shaft 4, a No. 1 synchronous wheel 6, a supporting seat 7, a servo motor 8, a No. 2 synchronous wheel 9 and a synchronous belt 10, the fixed plate 2 is symmetrically fixedly connected to the top surface of the base plate 1, a through hole is opened on the fixed plate 2, the bearing 3 is fixedly connected in the through hole, the rotating shaft 4 is rotatably connected inside the bearing 3, the No. 1 synchronous wheel 6 is fixedly connected to the outer ring surface of the rotating shaft 4, the supporting seat 7 is fixedly connected to the top surface of the base plate 1, the servo motor 8 is fixedly connected to the top surface of the supporting seat 7, the No. 2 synchronous wheel 9 is fixedly connected to the driving end of the servo motor 8, one end of the synchronous belt 10 is arranged on the No. 2 synchronous wheel 9, and the other end of the synchronous belt 10 is arranged on the No. 1 synchronous wheel 6, one end of the rotating shaft 4 is fixedly connected to the clamping assembly 5, and the servo motor 8 rotates 180 degrees each time.

[0035] In the utility model, the switch of the servo motor 8 is turned on, and the servo motor 8 rotates to drive the second synchronous wheel 9 to rotate, and the second synchronous wheel 9 drives the synchronous belt 10 to move, and drives the first synchronous wheel 6 to rotate. Because the first synchronous wheel 6 is fixedly connected to the outer ring surface of the rotating shaft 4, it drives the rotating shaft 4 to rotate, and finally drives the clamping assembly 5 to rotate. Because the rotation angle of the servo motor 8 is 180 degrees, it can drive the clamping assembly 5 to achieve a 180-degree flip.

[0036] Furthermore, as a specific implementation of the present invention, the present invention provides a pneumatic puncher with a flip structure.

[0037] Specifically, Figure 3-4 As shown, it also includes: a clamping assembly 5, the clamping assembly 5 includes a wheel 501, a mounting frame 502, a rotating motor 503, a gear 504, a rack 505 and a grabbing clamp 506, the wheel 501 is fixedly connected to one end of the rotating shaft 4, the mounting frame 502 is fixedly connected to the side of the wheel 501, the rotating motor 503 is rotatably connected to the inner side of the mounting frame 502, the gear 504 is fixedly connected to one end of the rotating motor 503, the rack 505 is meshed with the gear 504, and the grabbing clamp 506 is fixedly connected to the side of the rack 505.

Because the rack 505 is engaged with the gear 504 and is symmetrically arranged at the left and right ends of the gear 504, the two racks 505 move in opposite directions, driving the clamp 506 to close or open.

[0039] Furthermore, as another specific implementation of the utility model, the utility model provides a pneumatic hole puncher with a flip structure.

[0040] Specifically, Figure 1-2 As shown, a movable plate 11 is disposed on the outer sleeve of the rotating shaft 4 .

[0041] In the present invention, the shaft 4 is rotatably connected inside the bearing 3. In order to ensure the balance of the shaft 4 and to ensure that the shaft 4 is always in a horizontal state, a movable plate 11 is sleeved on the position of the shaft 4 away from the bearing 3 for fixing.

[0042] Furthermore, as a specific implementation of the present invention, the present invention provides a pneumatic puncher with a flip structure.

[0043] Specifically, Figure 3-4 As shown, a guide groove is provided inside the installation frame 502, and the grab clip 506 is slidably connected inside the guide groove.

[0044] In the utility model, when the rack 505 moves up and down, the position may be offset in the horizontal direction due to the lack of a limit. In order to ensure that the route of the rack 505 moving up and down is a straight line, a guide groove for limiting is provided inside the installation frame 502, and raised blocks are provided on the sides of both ends of the gripping clamp 506, and the raised blocks on the gripping clamp 506 are slidably connected inside the guide groove.

[0045] Furthermore, as a specific implementation of the present invention, the present invention provides a pneumatic puncher with a flip structure.

[0046] Specifically, Figure 1-3 As shown, a connecting rod 507 is fixedly connected between the symmetrical grasping clamps 506 .

[0047] In the present invention, in order to reduce the use of excessive motors, a connecting rod 507 is provided between two symmetrical clamping assemblies 5. When the clamping assembly 5 at one end provided with the servo motor 8 rotates, the clamping assembly 5 at the other end can be driven to rotate through the connecting rod 507.

[0048] Furthermore, as a specific implementation of the present invention, the present invention provides a pneumatic puncher with a flip structure.

[0049] Specifically, Figure 1-2 As shown, a slide groove is provided on the top surface of the bottom plate 1, and the movable plate 11 is slidably connected inside the slide groove.

[0050] In the present invention, in order to facilitate the adjustment of the distance between the two symmetrical clamping components 5 and better adapt to the drilling of objects of different sizes, in order to be able to move the clamping components 5, a slide groove is opened on the top surface of the bottom plate 1, and the movable plate 11 is slidably connected inside the slide groove.

[0051] Furthermore, as a specific implementation of the present invention, the present invention provides a pneumatic puncher with a flip structure.

[0052] Specifically, Figure 3-4 As shown, the gripping clip 506 is provided with a groove, and anti-slip particles are arranged on the groove.

[0053] In the present invention, in order to facilitate the clamping of objects such as cards with smooth surfaces and prevent them from falling off or shifting during clamping, resulting in errors in the punching position, a groove is provided on the gripper 506, and anti-slip particles are arranged on the groove.

[0054] Working principle: turn on the switch of the servo motor 8, the servo motor 8 rotates to drive the second synchronous wheel 9 to rotate, the second synchronous wheel 9 drives the synchronous belt 10 to move, and drives the first synchronous wheel 6 to rotate. Because the first synchronous wheel 6 is fixedly connected to the outer ring surface of the rotating shaft 4, it drives the rotating shaft 4 to rotate, and finally drives the clamping assembly 5 to rotate. Because the rotation angle of the servo motor 8 is 180 degrees, it can drive the clamping assembly 5 to achieve a 180-degree flip. At this time, adjust the punching machine assembly 12 to punch holes on the front and back pages of the object placed on the carrier 13.

[0055] The rotation of the rotating shaft 4 drives the wheel 501 to rotate and drives the installation frame 502 to rotate, and the switch of the rotating motor 503 is turned on. The rotating motor 503 rotates and drives the gear 504 to rotate. Because the rack 505 is engaged with the gear 504 and is symmetrically arranged on the left and right ends of the gear 504, the two racks 505 move in opposite directions, driving the gripper 506 to close or open, thereby clamping and releasing the object.
