DETAILED DESCRIPTION

[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0019] Reference Figure 1-3 A punching mechanism for a flange fork comprises a base 1, a fork body 2 and a punching assembly 5. The fork body 2 is placed on the base 1. A cylinder 3 connected to the punching assembly 5 and a punching motor 4 are provided above the base 1. The cylinder 3 realizes the lifting and lowering of the punching motor 4 and the punching assembly 5. The cylinder 3 contacts the fork body 2 and descends to realize the punching process. The cylinder 3 can be installed on the top of a processing workshop or on other supporting components.

[0020] A mounting frame 6 is provided on the base 1, and a rotating block 8 is provided on the mounting frame 6 through a rotating mechanism. A rotating cavity 9 is provided inside the rotating block 8, and two movable grooves 12 are provided on the outer wall of the rotating block 8. Screws 13 extending into the rotating cavity 9 are rotatably provided in both movable grooves 12, and only a portion of the outer wall of the screw 13 located in the movable groove 12 is provided with threads.

[0021] A rotating motor 10 is arranged in the rotating chamber 9 , and a screw rod 13 is connected to the rotating motor 10 through a rotating mechanism. A movable block 15 threadedly connected to the screw rod 13 is arranged in the movable groove 12 , and a positioning frame 16 corresponding to the fork body 2 is installed on the movable block 15 .

[0022] The rotating mechanism includes a rotating motor 7 installed on the mounting frame 6. The output shaft of the rotating motor 7 rotates through the mounting frame 6 and is fixedly connected to the rotating block 8. The rotating motor 7 can realize the rotation adjustment operation of the rotating block 8, and finally realize the rotation of the fork body 2 on the base 1, and can realize the drilling operation in other places.

[0023] The rotating mechanism includes a rotating gear 11 installed on the output of the rotating motor 10, and a transmission gear 14 connected to the rotating gear 11 is installed on the screw 13. As shown in the figure, the rotating gear 11 and the transmission gear 14 are both bevel gears, which are vertically meshed with each other to play a role in power transmission. The direction of the threads on the two screws 13 is set according to their rotation direction to ensure that the two positioning frames 16 are moved away from or close to each other at the same time.

[0024] The four outer walls of the movable block 15 are in sliding contact with the four inner walls of the movable groove 12, and the surfaces where the movable block 15 and the movable groove 12 contact each other are polished. This design scheme enables the movable block 15 to have a self-limiting function so that it will not rotate with the screw 13.

[0025] The vertical section of the positioning frame 16 is U-shaped, and a protective pad 17 is provided on the vertical surface of the positioning frame 16. The protective pad 17 is made of rubber and has anti-slip grooves on the surface of the protective pad 17. This design is protective and anti-slip, ensuring stability during positioning and fixing. At the same time, the U-shaped design ensures that the fork body 2 will not be displaced in the vertical direction.

[0026] When the utility model is used, the fork body 2 is placed on the base 1, and then the rotating motor 10 is started to drive the rotating gear 11 to rotate. The rotating gear 11 can cooperate with the transmission gear 14 to drive the screw 13 to rotate. When the screw 13 rotates, the movable block 15 will move in the movable groove 12 and move out, and finally approach and position the fork body 2. At this time, the cylinder 3 extends to drive the punching motor 4 and the punching assembly 5 to descend to perform the punching operation. As shown in the figure, an annular collecting groove is provided on the base 1, and the waste chips generated by the punching can enter the collecting groove for collection.

[0027] After the current position is punched, the rotary motor 7 is started to drive the rotary block 8 to rotate on the mounting frame 6, so that the other positions of the fork body 2 can be rotated to correspond to the punching assembly 5, and then the punching operation of the next position can be carried out.

[0028] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
