It should be understood that the following text is only used to describe one or more specific embodiments of the present invention and does not strictly limit the scope of protection of the present invention.

[0022] As used herein, the terms "parallel," "perpendicular," and the like are not limited to their strict geometric definitions, but include allowances for reasonable and inconsistent machining or human errors.

[0023] like Figure 1 、 2As shown, an adjustment mechanism includes an X1 adjustment unit, an X2 adjustment unit, and a transmission connection unit. The transmission connection unit includes an adjustment shaft 11 arranged at an angle. A clamping device 01 for clamping the cast aluminum base 00 is provided at one end of the adjustment shaft 11. The middle portion of the adjustment shaft 11 is rotatably mounted in an adjustment mounting sleeve 12. The adjustment mounting sleeve 12 is rotatably mounted on the adjustment support seat 03 via an X1 shaft 13. The X1 shaft 13 is arranged horizontally and perpendicular to the adjustment shaft 11. The X1 adjustment unit adjusts the adjustment shaft 11 to rotate, and the X2 adjustment unit adjusts the adjustment shaft 11 to rotate about the X1 shaft 13. The X1 adjustment unit is used to adjust different surfaces to be drilled on the cast aluminum base 00 assembled on the clamping device 01 to be in a working state. The working state refers to a state in which a surface to be drilled on the cast aluminum base 00 and a drilling drill on the drilling device are arranged facing each other. The preferred working state is a state in which the surface to be drilled facing the drilling drill is arranged horizontally. The X1 adjustment unit is used to adjust so that the surface to be punched on different models of cast aluminum base 00 can be rotated to a state where it is arranged opposite to the punching drill bit, thereby achieving the adjustment requirement of reliable drilling.

[0024] The transmission connection unit also includes a horizontally arranged and rotatably mounted drive shaft 20. A transition shaft assembly is disposed between the drive shaft 20 and the adjustment shaft 11. One end of the transition shaft assembly is assembled and connected to one end of the drive shaft 20 via an X1 coupling 18, and the other end of the transition shaft assembly is assembled and connected to the other end of the adjustment shaft 11 via an X2 coupling 19. The drive shaft 20, transition shaft, and adjustment shaft 11, which comprise the same transmission connection unit, are located in the same vertical plane. The X1 adjustment unit is in transmission connection with the drive shaft 20. The X1 coupling 18 and X2 coupling 19 are cross-shaft couplings. The transition assembly includes a transition shaft body 14, with both ends of the transition shaft body 14 being composed of spline shaft 17 sleeves. The two spline shaft 17 sleeves are respectively provided with spline shafts 17 bodies that are slidably assembled therewith. The two spline shafts 17 bodies are respectively connected to the drive shaft 20 and the adjustment shaft 11 through the X1 coupling 18 and the X2 coupling 19. The middle part of the transition shaft body 14 is rotatably assembled in the transition mounting sleeve 15. The transition mounting sleeve 15 is rotatably mounted on the transition support seat 04 through the X2 shaft body 16. The X2 shaft body 16 and the transition shaft are arranged perpendicularly, and the X1 shaft body 13 and the X2 shaft body 16 are arranged parallel. The X1 adjustment unit adjusts the drive shaft 20 to rotate, and the X2 adjustment unit adjusts the drive shaft 20 to lift. In specific operation, the X1 shaft body 13 is composed of two X1 ear shafts, and the X2 shaft body 16 is composed of two X2 ear shafts. The adjustment support seat 03 and the transition support seat 04 are fixedly mounted on the rotating mounting seat 31. The above-described transmission mechanism not only satisfies the requirements for the adjustment shaft 11 to rotate on its own and around the X1 axis 13, but also features a simple structure and easy adjustment. The central portion of the drive shaft 20 is rotatably mounted on the drive support 23, which is fixedly mounted around the periphery of the lift mount 32. The lift mount 32 is assembled in a lifting manner, and the X2 adjustment unit is used to adjust the lift mount 32 for elevation. Transmission connection units are spaced circumferentially around the lift mount 32, and the drive shaft 20 is arranged radially around the lift mount 32. A rotating mount 31 is provided below the lift mount 32, which is rotatably mounted on the frame 30. Vertical guide rods 34 are spaced around the rotating mount 31, and the lift mount 32 is slidably mounted on the guide rods 34. An upper mount 33 is provided at the upper end of the guide rod 34, and the X1 drive motor 28 is mounted on the upper mount 33. The guide rods 34 and the drive shaft 20 are spaced circumferentially around the lift mount 32 to prevent interference.

[0025] Detailed plan such as Figure 2 、 3As shown, the other end of the drive shaft 20 is provided with a transmission bevel gear 21. The X1 adjustment unit includes a drive bevel gear 24 and an X1 drive motor 28, which are rotatably mounted on a lifting mount 32. The drive bevel gears 21, which constitute the transmission connection unit, are meshed and transmission-connected with the drive bevel gears 24. The drive bevel gear 24 is provided with an X1 spline sleeve 26 arranged concentrically therewith. The X1 spline sleeve 26 is assembled and connected to the drive bevel gear 24 via a one-way bearing 25. The output shaft of the X1 drive motor 28 is transmission-connected to the X1 transmission shaft 27, which is rotatably mounted on the frame 30. The lower end of the X1 transmission shaft 27 is provided with an X1 spline shaft section 17, which is assembled and connected to the X1 spline sleeve 26. The X1 adjustment unit can synchronously rotate each adjustment shaft 11 connected to the clamping device, so that the cast aluminum base 00 at each workstation is replaced with a new surface to be punched and put into operation, thereby ensuring the consistency of replacement of each surface to be punched. In addition, different models of cast aluminum bases 00 require different angles to adjust when replacing the punching surface. The above-mentioned X1 adjustment unit only needs to adjust the rotation angle of the drive bevel gear 24 to adapt to the adjustment requirements of different models of cast aluminum bases 00, and the adjustment is convenient and fast. A vacant portion is provided in the middle of the rotating mounting seat 31. The X2 adjustment unit includes an X2 connecting rod 42 arranged concentrically with the rotating mounting seat 31. A mounting tube 35 is provided on the lower surface of the rotating mounting seat 31. The mounting tube 35 is connected to the X2 drive motor 37 through the X2 transmission assembly 36. The upper end of the X2 connecting rod 42 passes through the mounting tube 35 and is rotatably assembled and connected to the lifting mounting seat 32. The lower end of the X2 connecting rod 42 is connected to the X2 drive member 41. The X2 drive member 41 can be composed of a lifting electric cylinder, an oil cylinder, an air cylinder, or a lifting motor. It can also be composed of a lifting motor to perform lifting adjustment on the lifting mounting seat 32, thereby adjusting the surface to be punched of different models of cast aluminum bases 00 to a working state. The X2 adjustment unit can rotate each adjustment shaft 11 connected to the clamping device about the X1 axis 13, thereby achieving the required adjustment of the tilt angle of the adjustment shaft 11 when drilling holes in different models of cast aluminum base 00, and the adjustment is convenient and fast. The X2 transmission assembly 36 can specifically be a chain drive assembly, a belt drive assembly, or other transmission assembly capable of achieving transmission. In specific operation, the X2 transmission assembly 36 includes an X1 sprocket mounted on the mounting tube 35 and an X2 sprocket mounted on the output shaft of the X2 drive motor 37. The X1 sprocket and the X2 sprocket are connected by a transmission chain. When the X2 drive motor 37 drives the rotating mounting base 31 to rotate, the direction in which the X2 drive motor 37 drives the rotating mounting base 31 is the forward direction. When the rotating mounting base 31 rotates in the forward direction, the one-way bearing 25 is in a transmission disconnected state. The X1 drive motor 28 drives the drive bevel gear 24 to rotate in the reverse direction. At this time, the transmission of the one-way bearing 25 is in a transmission connected state. The X2 connecting rod rotates in a non-contact state with the mounting tube and the rotating mounting base.

[0026] The present invention also provides a punching device, the structure of which is as follows: Figure 4 As shown, it includes a frame 30, a rotating mounting base 31 rotatably mounted on the frame 30, and an adjustment mechanism. The rotating mounting base 31 is provided with a loading station, an unloading station, and various punching stations at intervals in the circumference. The loading station is provided with a loading mechanism, the unloading station is provided with an unloading device, and each punching station is provided with a punching device. The number of punching stations is consistent with the number of surfaces to be punched on the cast aluminum base 00. For example, one loading station, one unloading station, and six punching stations can be provided, and 8 groups of clamping devices are provided on the cover body, and 8 groups of corresponding transmission connection units are also provided. The loading device and the unloading device can be the same and constituted by a robot. The loading device and the punching device can be implemented using the loading mechanism and the punching device in the punching equipment previously applied for, or other devices with the same functions can be used. The clamping device 01 can be a pneumatic clamping device 01, specifically a pneumatic clamping chuck. The air inlet and outlet ports of the clamping chuck are connected to the air source regulating device via a rotary joint, and the air source regulating device can be provided on the top mounting seat. The cast aluminum base 00 is centered, clamped, fixed, and loosened by activating the claws on the clamping chuck. A cover 38 is provided on the upper side of the rotating mounting seat 31, and an assembly hole is provided on the cover 38. The periphery of the clamping device 01 is connected to the periphery of the assembly hole via a soft part 02 to prevent debris generated by drilling from entering the area between the cover 38 and the rotating mounting seat 31. The rotating mounting seat 31 is located in a slot 39 provided on the frame 30.

[0027] The above-mentioned solution provided by the present invention can realize reliable and convenient adjustment of the self-rotation of the adjustment shaft and the rotation around the X1 axis, and can be effectively used in turntable-type automation equipment to realize reliable drilling processing of the cast aluminum base.
