[0002] Flange is a disc-shaped component, which is the most common in pipeline engineering and is usually used in pairs. In pipeline engineering, flanges are mainly used for pipe connection. At the ends of two pipes that need to be connected, a flange is installed at each end, and then the two flanges are locked by bolts. In order to facilitate the docking of flanges, a circle of mounting holes needs to be opened on the edge of the flange. The traditional processing method is to first find the center of the flange, and then use the center as the starting point to find the position to be punched on the end face of the flange through a linear scale, and then use this point as a reference to determine the angle between the mounting holes through a protractor, and mark each drilling position. Finally, the flange is fixed and clamped on the fixture of the drilling machine, and the mounting holes are drilled at the drilling marks by operating the drilling machine. In the above process, the determination of the center of the flange and the determination of the drilling mark are very cumbersome, which requires a lot of effort from the operator, and there are large processing errors, which makes it difficult to meet the requirements of high-precision drilling.

DETAILED DESCRIPTION
[0017] Now the utility model is described in detail with reference to the accompanying drawings. This figure is a simplified schematic diagram, which only illustrates the basic structure of the utility model in a schematic manner, so it only shows the components related to the utility model.
[0018] See also Figure 1 , Figure 2 The utility model provides a flange mounting hole punching device, including a base 1, a three-jaw chuck 2, a driving mechanism 3 and a drilling mechanism 4. The base 1 is used to support a flange 10 to be punched, the three-jaw chuck 2 is used to clamp the flange 10, the driving mechanism 3 is used to drive the three-jaw chuck 2 to rotate, thereby driving the flange 10 to rotate, and the drilling mechanism 4 can be movably arranged above the base 1, and is used to open a mounting hole on the end surface of the flange 10.
[0019] A plurality of supporting feet 11 are installed on the lower surface of the base 1, and the supporting feet 11 are placed on a bearing plane (for example, the floor of a processing workshop) to set up the base 1. A avoidance hole (not shown) is opened in the middle of the base 1, and the claws of the three-jaw chuck 2 pass through the avoidance hole from bottom to top, so that the three claws protrude to the upper surface of the base 1. When in use, the flange 10 to be punched is sleeved on the outside of the claws on the three-jaw chuck 2, and then the flange 10 is operated to expand the claws outward, and finally, the three claws are jointly supported on the wall of the center hole of the flange 10 to clamp and fix the flange 10. Since the three-jaw chuck has a self-centering function, when the flange 10 is clamped and fixed on the three-jaw chuck 2, the flange 10 facilitates the three-jaw chuck 2 to be in a coaxial state. In this embodiment, the disk body of the three-jaw chuck 2 is rotatably mounted on the base 1. In a specific embodiment, a bearing is arranged between the disc body of the three-jaw chuck 2 and the base 1 to achieve a supporting effect on the three-jaw chuck 2 and facilitate the smooth rotation of the three-jaw chuck 2 relative to the base 1.
[0020] As a preferred embodiment, the driving mechanism 3 includes a driven gear 31, a driving gear 32 and a driving motor 33. The central axis of the driven gear 31 is fixedly connected to the bottom of the body of the three-jaw chuck 2, the body of the driving motor 33 is fixedly connected to the base 1, the output shaft of the driving motor 33 is fixedly connected to the central axis of the driving gear 32, and the driven gear 31 and the driving gear 32 are meshed with each other. When in use, the driving motor 33 rotates, thereby driving the driving gear 32 to rotate, and further driving the driven gear 31 to rotate. At this time, the three-jaw chuck 2 and the flange 10 rotate synchronously relative to the base 1. In specific implementation, the operator can control the number of rotations of the driving motor 33 through the PLC control cabinet, and then control the rotation angle of the flange 10 to meet the needs of drilling holes at different positions.
[0021] In addition, the outer diameter of the driving gear 32 is smaller than the outer diameter of the driven gear 31 , so that the driven gear 31 can reduce the speed of the movement, so that the flange 10 can rotate stably.
[0022] A long groove 13 is opened on the base 1 along the radial direction of the three-jaw chuck 2, and the drilling mechanism 4 includes an electric drill 41 and a bracket 42. The bracket 42 is fixedly connected to the base 1. The electric drill 41 is located directly above the long groove 13 and can slide relative to the bracket 42 along the radial direction of the three-jaw chuck 2. A scale 45 is set on the bracket 42 along the length direction of the long groove 13. The scale 45 is used to display the distance from the drill bit of the electric drill 41 to the center of the three-jaw chuck 2.
[0023] When the flange 10 is clamped in place, the user can use the movable electric drill 41 to determine the center distance between the electric drill 41 and the three-jaw chuck 2 according to the scale 45, which is also the distance between the position to be drilled on the flange 10 and the center distance of the three-jaw chuck 2, and then start the electric drill 41 and control the electric drill 41 to move downward in the longitudinal direction, and finally drill the installation hole on the flange 2. The function of the long groove 13 is to avoid the drill bit on the downwardly movable electric drill 41 to prevent the drill bit from contacting the base 1.
[0024] As a preferred embodiment, the bracket 42 is an L-shaped structure, and the bracket 42 includes a longitudinal rod 421 and a transverse rod 422. The lower end of the longitudinal rod 421 is fixedly connected to the base 1, and the transverse rod 422 extends along the radial direction of the three-jaw chuck 2. The drilling mechanism 4 also includes a slider 43 and a cylinder 44. The slider 43 is slidably arranged on the transverse rod 422 along the extension direction of the transverse rod 422. The cylinder body of the cylinder 44 is fixedly connected to the bottom of the slider 43, and the body of the electric drill 41 is fixedly connected to the extended end of the cylinder 44. When in use, the horizontal position of the electric drill 41 is adjusted by sliding the slider 43, and the vertical position of the electric drill 41 is adjusted by the cylinder 44.
[0025] As a preferred embodiment, a slide groove 4221 is provided on the cross bar 422 along its extension direction, and the slider 43 is a T-shaped block. The bottom of the slider 43 is slidably fitted in the slide groove 4221, and the top of the slider 43 is mounted on the upper surface of the cross bar 422, so that the slider 43 is slidably mounted on the cross bar 422, and the slider 43 will not be separated from the cross bar 422. Further, a plurality of threaded holes 4222 are provided on the side wall of the cross bar 422 along the extension direction of the cross bar 422, and the threaded holes 4222 are connected to the slide groove 4221, and bolts 4223 are installed in the threaded holes 4222, and one end of the bolt 4223 extends into the slide groove 4221 and abuts against the slider 43, so that when the slider 43 is adjusted to the position relative to the cross bar 422, the slider 43 can be pressed against the cross bar 422 by tightening the bolts 4223.
[0026] As a preferred embodiment, the scale 45 is fixedly mounted on the crossbar 422. When in use, the user can know the center distance from the drill bit of the electric drill 41 to the three-jaw chuck 2 through the alignment relationship between the end face of the slider 43 and the scale lines on the scale 45. In specific implementation, since the distance from the drill bit of the electric drill 41 to the end of the slider 43 that is aligned with the scale lines is a specific fixed value, the zero position on the scale 45 can be set to the center position of the three-jaw chuck 2. At this time, the user can obtain the center distance from the drill bit of the electric drill 41 to the three-jaw chuck 2 by subtracting the above-mentioned specific fixed value from the scale indication on the scale 45 aligned with the end face of the slider 43.
[0027] The flange mounting hole punching device of the present invention is used in the following process: first, the flange 10 to be punched is simultaneously mounted on the three jaws of the three-jaw chuck 2, and then the three-jaw chuck 2 is operated to clamp the flange 10. At this time, the center of the flange 10 corresponds to the zero position of the scale 45. Then, the slider 43 is slid as needed, and the drill bit of the electric drill 42 is moved to the target position, and the slider 43 is locked on the bracket 42 by the bolt 4223. Finally, the electric drill 41 can be driven downward by the cylinder 44 to finally drill the mounting hole on the flange 10. Compared with the traditional punching method, the operation is simple and convenient, and a lot of energy does not need to be consumed. The punching accuracy is accurate, and the quality of the product is improved.
