[0034] The bidirectional lead screw 107 is coaxially fixedly connected with the transmission bevel gear 2 111, the transmission bevel gear 2 111 is meshed with the transmission bevel gear 1 110, the transmission bevel gear 1 110 is coaxially fixedly connected with the transmission incomplete gear 109, the transmission incomplete gear 109 is fixedly mounted on the rotating shaft 108, the rotating shaft 108 is rotatably mounted on the platform 101, the transmission incomplete gear 109 cooperates with the transmission spur gear 112, the transmission spur gear 112 is coaxially fixedly connected with the bidirectional lead screw 2 113, the bidirectional lead screw 2 113 is rotatably mounted on the platform 101, the bidirectional lead screw 2 113 is threadedly connected with the push plate 2 114, the push plate 2 114 is slidably mounted on the platform 101, and the bidirectional lead screw 2 113 rotates one circle to drive the push plate 2 114 to reciprocate once.

[0035] A lower pressing plate 203 is slidably mounted on the punching platform 201 , a connecting rod 204 is mounted on the lower pressing plate 203 , the connecting rod 204 is connected to a connecting ring 205 , the connecting ring 205 is connected to a piston rod of a hydraulic cylinder 206 , the hydraulic cylinder 206 is mounted on the punching platform 201 , and anti-slip grooves are provided on the lower pressing plate 203 .

[0036] A conveyor belt 102 is provided on the platform 101 . The conveyor belt 102 is driven by a conveying motor 104 . The conveyor belt 102 is used to transport the retaining frame 3 . A guide plate 103 is installed on the platform 101 . The guide plate 103 is used to limit the position of the retaining frame 3 .

[0037] The working principle of the present invention is as follows: start the transmission motor 2 122 to drive the transmission active gear 123 to rotate, drive the clamping gear ring frame 115 to rotate, the rotation of the clamping gear ring frame 115 drives the three clamping components in the guide groove of the clamping gear ring frame 115 to move, drive the clamping sliding column 116 and the clamping sliding rod 117 to move toward the axis direction of the punching platform 201, the three clamping components operate synchronously, and the retaining frame 3 on the punching platform 201 is pushed to the specified position for positioning through the three arc-shaped push blocks 121, so that the axis of the retaining frame 3 is in line with the axis of the punching platform 201, start the hydraulic cylinder 206 to extend the piston rod to drive the lower pressure plate 203 to slide down, and the retaining frame 3 is pressed tightly against the punching platform 201 through the lower pressure plate 203.

[0038] The punching motor 207 is started to drive the punching incomplete gear 1 208 and the punching incomplete gear 2 209 to rotate. The punching incomplete gear 1 208 rotates a preset angle to mesh with the punching large gear 211. The punching incomplete gear 1 208 drives the punching large gear 211 and the punching platform 201 to rotate a preset angle. Then the punching incomplete gear 1 208 is disengaged from the punching large gear 211. The punching incomplete gear 2 209 that continues to rotate contacts and meshes with the punching pinion 210, driving the punching pinion 210 to rotate one circle. The punching pinion 210 rotates to drive the punching cone gear The wheel 1 212 rotates, driving the punching bevel gear 213 to rotate, driving the punching bidirectional lead screw 214 to rotate, driving the drill bit seat 215 to slide back and forth once on the platform 101, driving the two drill bits 216 to move, and the retaining frame 3 is punched by the drill bits 216. After punching a hole, the punching incomplete gear 209 that continues to rotate is disengaged from the punching small gear 210, and the punching incomplete gear 1 208 rotates a preset angle and then meshes with the punching large gear 211 again, driving the punching large gear 211 to rotate a preset angle. The principle is the same as above, and the retaining frame 3 is evenly punched.

[0039] After the drilling is completed, the transmission motor 2 122 reverses, driving the transmission driving gear 123 and the push plate 1 105 to reverse and drive the three clamping components of the retainer to return to the initial position, and the hydraulic cylinder 206 retracts the piston rod to drive the lower pressure plate 203 to slide, so that the lower pressure plate 203 no longer presses the retainer 3.

[0040] The transmission motor 104 drives the conveyor belt 102 to operate, and the plurality of retainers 3 are transmitted in the direction of the bidirectional lead screw 107 through the conveyor belt 102. The retainer 3 closest to the bidirectional lead screw 107 stops moving after contacting the guide plate 103, and the transmission motor 106 is started to drive the bidirectional lead screw 107 and the transmission bevel gear 111 to rotate. The bidirectional lead screw 107 drives the push plate 105 to move, and the transmission bevel gear 111 drives the transmission bevel gear 110 to rotate. The transmission bevel gear 110 drives the transmission incomplete gear 109 and the rotating shaft 108 to rotate. When the bidirectional lead screw 107 rotates half a circle, the push plate 105 moves to the position where it can move. At the maximum displacement point of the movement, the push plate 105 pushes the unpunched retainer 3 to the position of the punching platform 201, and at this time, the tooth structure on the transmission incomplete gear 109 begins to contact the transmission spur gear 112. The tooth structure on the transmission incomplete gear 109 drives the transmission spur gear 112 to rotate one circle during the contact and separation process, and then the bidirectional lead screw 107 continues to rotate and drives the push plate 105 to return, and the rotation of the incomplete transmission gear 109 drives the transmission spur gear 112 to rotate, and the transmission spur gear 112 rotates one circle, which drives the bidirectional lead screw 2 113 to rotate one circle, and drives the push plate 2 114 to reciprocate once.

[0041] When push plate 105 pushes the unpunched retainer 3 in the direction of push plate 2 114, the unpunched retainer 3 pushes the punched retainer 3 on the punching platform 201 to the position of push plate 2 114, and the reciprocating push plate 2 114 pushes the punched retainer 3 to the feeding station.

[0042] Under normal circumstances, the position of the clamping connecting plate 120 is higher than the upper surface of the punching platform 201. Therefore, the retaining frame 3 after punching contacts the inclined surface of the arc-shaped push block 121 of one of the clamping components during the pushing process, pressing down the clamping connecting plate 120, driving the clamping slide 119 to move down and compress the clamping spring 118 to make way.

[0043] It should be understood that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. For those skilled in the art, the technical solutions described in the above embodiments can be modified, or some of the technical features therein can be replaced by equivalents; and all these modifications and replacements should fall within the scope of protection of the claims attached to the present invention.
