[0023] The present invention is further described below in conjunction with the accompanying drawings and specific implementation methods.

[0024] like Figures 1 to 3 As shown, the present invention includes a frame assembly, a drilling assembly, a driving assembly and a clamping assembly.

[0025] The frame assembly includes a frame 17 , guide rods 12 and a motor base 1 . Four guide rods 12 are installed on the frame 17 . The four guide rods 12 are distributed in a square shape. One end of the frame 17 is fixedly connected to the motor base 1 .

[0026] The guide rod 12 is slidably matched with the clamping assembly, and a driving assembly is installed on the frame 17, which can drive the clamping assembly to slide along the guide rod 12. Figure 6 and 7As shown, the clamping assembly includes a clamping plate 11, a clamping plate 18 and a limit pin 25. Guide sleeves 14 are respectively provided on the four corners of the clamping plate 11. The guide rod 12 passes through the guide sleeve 14 and slides with it. A center through hole is provided at the center of the clamping plate 11, and a threaded through hole is provided at the center of the clamping plate 18. One end of the fastening bolt 28 passes through the center through hole of the clamping plate 11 and threadedly cooperates with the threaded through hole of the clamping plate 18.

[0027] A stop ring 26 is provided on one end surface of the clamping plate 11. The stop ring 26 and the central through hole of the clamping plate 11 are located on the same axis. The inner diameter of the stop ring 26 is the same as the outer diameter of the flange 30, so that the flange 30 can be easily positioned. The clamping plate 11 is provided with a plurality of positioning through holes, which are evenly distributed in a circle with the axis of the central hole of the clamping plate 11 as the center.

[0028] A locking plate 27 is fixedly mounted on the upper end of the clamping plate 11 . A limiting through hole is provided on the locking plate 27 . The limiting through hole corresponds to one of the positioning through holes of the clamping plate 11 . A limiting latch 25 is inserted into the limiting through hole.

[0029] The driving device includes a screw 13, a screw nut 15, a first motor 5 and a first transmission device. A screw 13 is provided on both sides of the frame 17. One end of the screw 13 is rotatably connected to the frame 17, and the other end is connected to the motor shaft of the first motor 5 through the first transmission device. The two sides of the clamping plate 11 are fixedly connected to the screw nut 15 respectively, and the screw 13 cooperates with the screw nut 15. A connecting frame 29 is fixedly installed at one end of the frame 17, and the connecting frame 29 is fixedly connected to the first motor 5.

[0030] like Figure 5 As shown, in this embodiment, the first transmission device is a first belt transmission device, which includes a first active synchronous pulley 20, a first driven synchronous pulley 23 and a first synchronous belt 22. The first active synchronous pulley 20 is fixedly connected to the motor shaft of the first motor 5, and the two lead screws 13 are fixedly connected to the first driven synchronous pulley 23. The first active synchronous pulley 20 and the two first driven synchronous pulleys 23 are connected through the first synchronous belt 22. One end of the frame 17 is rotatably matched with the two first pressure wheels 21 through an axis. The two first pressure wheels 21 are pressed on the outside of the first synchronous belt 22, squeezing the first synchronous belt 22 into an inverted T shape, so that the wrap angle between the first synchronous belt 22 and the first active synchronous pulley 20 and the first driven synchronous pulley 23 is not less than 180°.

[0031] The two ends of the frame 17 are respectively installed with a drilling assembly, which includes a second motor 2, a fixing frame 16 and a drill bit 10. The fixing frame 16 is provided with four rotating sleeves 8. The through holes of the rotating sleeves 8 are rotatably matched with the rotating shaft. The inner end of the rotating shaft is fixedly connected to the drill chuck 9, and the outer end is connected to the second motor 2 through the second transmission device. The second motor 2 is fixedly installed on the motor base 1, and the drill chuck 9 is connected to the drill bit 10. Figure 4 As shown, the second transmission device is a second belt transmission device, which includes a second active synchronous pulley 24, a second driven synchronous pulley 6 and a second synchronous belt 3. The motor shaft of the second motor 2 is fixedly matched with the second active synchronous pulley 24, and the outer end of the rotating shaft is fixedly matched with the second driven synchronous pulley 6. The second active synchronous pulley 24 and the four second driven synchronous pulleys 6 are connected through the second synchronous belt 3. The outer ends of the fixed frame 16 are rotatably connected with the two second pressure wheels 4 through shafts respectively. The two second pressure wheels 4 are pressed on the outside of the second synchronous belt 3, so that the wrap angle between the second driven synchronous pulley 6 and the second synchronous belt 3 is not less than 90°.

[0032] The first transmission device and the second transmission device can also be a chain transmission device and a gear transmission device. The chain transmission device is the same as the belt transmission device, except that the synchronous belt is replaced by a chain, and the synchronous belt wheel is replaced by a sprocket. The gear transmission device is that the motor drives the driving gear to rotate, and the driving gear drives the driven parts such as the lead screw and the rotating shaft to rotate through the driven gear.

[0033] The drill bits 10 of the two drilling assemblies are staggered and correspond to different positioning through holes of the clamping plate 11, respectively, wherein the positioning through holes corresponding to the drill bit 10 of one drilling assembly are adjacent to the positioning holes corresponding to the drill bit 10 of the other drilling assembly.

[0034] In this embodiment, the lower end of the frame 17 is rotatably connected to the transmission shaft 19, one end of the transmission shaft 19 is connected to the motor shaft of the second motor 2 through a coupling, and the other end is fixedly matched with two second active synchronous pulleys 24 in sequence.

[0035] The operation process is as follows: when using the device, the flange 30 is placed in the limit ring 26 of the clamping plate 11, and the clamping plate 18 is rotated so that the flange 30 is clamped between the clamping plate 18 and the clamping plate 11. The first motor 5 and the second motor 2 are started respectively, and the second motor 2 drives the drill bit 10 to rotate through the second transmission device, and the first motor 5 drives the lead screw 13 to rotate through the first transmission device. Since the lead screw 13 cooperates with the lead screw nut 15, the lead screw 13 drives the clamping assembly to move to the position of the drilling assembly, so that the drill bit 10 drills the flange 30. By controlling the forward and reverse rotation of the first motor 5, the clamping assembly can be driven to move along the two ends of the guide rod 12 respectively, so that the drill bits 10 of the drilling assemblies at the two ends of the frame 17 drill the flange 30 respectively. When the flange 30 has drilled a group of holes, the flange 30 is rotated so that the limit pin 25 is inserted into one of the drilled holes of the flange 30, and the above steps are repeated to continue drilling the flange 30.

[0036] It should be noted that the specific embodiments of the present invention have been described in detail. For those skilled in the art, various obvious changes to the present invention without departing from the spirit and scope of the present invention are within the protection scope of the present invention.
