Detailed Implementation

[0022] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0023] like Figures 1-5 As shown in the figure, this utility model embodiment proposes a positioning and drilling device for flange production, comprising:

[0024] A support frame 1 is provided, on which a workbench 2 is mounted. A detachable support plate 8 for supporting the flange is mounted on the workbench 2, with the support plate 8 abutting against the upper end of the workbench 2. A rectangular groove 10 is provided through the workbench 2, and a rectangular block 11 is slidably connected within the groove 10. The rectangular block 11 is fixedly connected to the support plate 8, preventing the support plate 8 from rotating. The support plate 8 supports the flange. However, since the support plate 8 is detachable, if the flange drilling position is opposite to the support plate 8, the drilling machine 16 may abut against the support plate 8, causing damage to the drill bit. Therefore, the support plate 8 needs to be replaced to meet actual drilling requirements.

[0025] The flange positioning mechanism includes a rotatable first electric push rod 17. A mounting bracket 3 is fixedly installed on the upper end of the worktable 2. A driving component is installed on the mounting bracket 3. A short shaft is fixed to the shaft end of the driving component. An inverted U-shaped plate 6 is fixed to the bottom of the short shaft. A horizontal plate 7 is fixed to the bottom of the U-shaped plate 6. The first electric push rod 17 is installed on the horizontal plate 7. The output end of the first electric push rod 17 is rotatably connected to a conical platform 9 for flange positioning. An installation rod is fixed to the output end of the first electric push rod 17. The conical platform 9 and the installation rod are rotatably installed.

[0026] The driving component includes a drive housing 4 mounted on a mounting bracket 3. A meshing worm gear 21 and worm wheel 22 are rotatably mounted inside the drive housing 4. A first motor 5 is mounted on the drive housing 4. The output end of the first motor 5 is fixedly connected to the worm gear 21, and the short shaft is coaxially fixedly connected to the worm wheel 22. The operation of the first motor 5 drives the worm gear 21 to rotate, which in turn drives the worm wheel 22 to rotate, thereby enabling the short shaft and the U-shaped plate 6 to rotate. The rotation of the U-shaped plate 6 then drives the horizontal plate 7 and the first electric push rod 17 to rotate.

[0027] Two sets of flange drilling mechanisms are distributed on both sides of the conical platform 9 and can rotate with the first electric push rod 17. The flange drilling mechanism includes an adjustable moving block 15. A second electric push rod 18 is fixedly connected to the horizontal plate 7. A mounting plate 12 is fixed to the output end of the second electric push rod 18. In order to ensure the stable up and down movement of the mounting plate 12, a guide rail 19 is fixed to the bottom of the horizontal plate 7. A guide block 20 is slidably connected to the guide rail 19. The guide block 20 is fixedly connected to the mounting plate 12.

[0028] The second motor 13 is installed on the mounting plate 12, the output end of the second motor 13 is fixed with a lead screw 14, a moving block 15 is slidingly connected to the bottom of the mounting plate 12, the lead screw 14 penetrates through the moving block 15 and is in threaded connection with the moving block 15, the bottom of the moving block 15 is installed with a puncher 16, due to different sizes of flanges, the positions to be punched are also different, the second motor 13 drives the lead screw 14 to rotate, the lead screw 14 drives the moving block 15 and the puncher 16 to slide until the puncher 16 moves to the position to be punched, and then the second motor 13 stops working, so that the puncher can be applicable to punching flanges of different sizes.

[0029] The puncher 16 is composed of a driving motor and a drill bit, the drill bit is detachably installed on the output end of the driving motor, the output end of the driving motor is installed with a structure similar to a three-jaw chuck, for example, the structure of fixing the drill bit of the electric hammer, which will not be described in detail and illustrated as prior art; the position of the puncher 16 can be adjusted by adjusting the position of the moving block 15, and the flange is punched by the puncher 16.

[0030] The flange to be punched is placed on the supporting disc 8, the first electric push rod 17 drives the conical table 9 to move downward and be located in the center hole of the flange, the flange can be centered by the conical table 9, and finally the conical table 9 abuts against the inner wall of the flange to realize the centering and fixing of the flange.

[0031] Then the second electric push rod 18 drives the mounting plate 12 and the puncher 16 to move downward, the two punchers 16 can punch simultaneously at the symmetrical positions of the flange, so that the punching efficiency is improved; after the punching is completed, the output end of the second electric push rod 18 drives the puncher 16 to reset, the driving member drives the U-shaped plate 6, the horizontal plate 7 and the puncher 16 to rotate, so that the puncher 16 faces the position to be punched, and then the driving member stops working, and the output end of the second electric push rod 18 drives the puncher 16 to move downward to punch;

[0032] The angle of the U-shaped plate 6 driven by the driving member is 180°, so that the circuit can be arranged without affecting the working of the equipment.

[0033] Finally, it should be pointed out that the above embodiments are only used to illustrate the technical solutions of the present application but not limit the present application, although the present application has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the technical solutions of the present application can be modified or replaced equivalently without departing from the purpose and scope of the present application, and all of them should be covered in the scope of the claims of the present application.
