DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0022] Please refer to Figures 1-4 , the present utility model provides a technical solution: a flange drilling device that is convenient for quick clamping. According to Figure 1 , Figure 2 and Figure 4 as shown, an electric guide rail 2 is arranged inside the upper end of the base 1, and a moving slide 3 is arranged at the upper end of the electric guide rail 2. At the same time, a clamping assembly 4 is arranged on the moving slide 3. The electric guide rail 2 drives the moving slide 3 and the clamping assembly 4 to move horizontally, so that other drilling positions of the flange body 405 are located directly below the drill bit 609, thereby drilling different positions of the flange body 405. The clamping assembly 4 includes a limit frame 401, and an electric rotating seat 402 is arranged at the lower end inside the limit frame 401. At the same time, the upper end of the electric rotating seat 402 is connected to the lower end of the placement seat 404 through a plurality of electric push rods 403. The middle of the upper end of the placement seat 404 is engaged with the lower end of the flange body 405. The placement seat 404 and the limit frame 401 form a rotating structure through the electric rotating seat 402. The electric rotating seat 402 drives the electric push rods 403 and the placement seat 404 to rotate, which is convenient for rotating the flange body 405 placed on the upper end of the placement seat 404, so that the position of the flange body 405 that needs to be drilled can be in the same horizontal vertical plane as the drill bit 609. Then, under the horizontal movement of the electric guide rail 2 and the moving slide 3, the drilling position is located below the drill bit 609, and different positions of the flange body 405 can be drilled. At the same time, a plurality of positioning holes 4041 are opened at the bottom of the placement seat 404 at the lower end of the flange body 405, and the placement seat 404 is engaged and connected with the positioning groove opened at the upper end inside the limit frame 401. A plurality of installation grooves are equidistantly opened on the outer side of the placement seat 404, and a fixed bracket 406 is rotatably connected inside each installation groove. At the same time, the outer side of the upper end of the fixed bracket 406 is slidably connected with the corresponding groove 4011 opened at the upper end of the limit frame 401. The placement seat 404 and the limit frame 401 form a lifting structure through the electric push rod 403. The electric push rod 403 drives the placement seat 404 to move downward, so that the fixed bracket 406 rotating on the outer side of the placement seat 404 rotates towards the flange body 405, and the fixed bracket 406 is clamped between the placement seat 404 and the limit frame 401 to position the outer side of the upper end of the flange body 405, thereby improving the stability during the drilling of the flange body 405.

[0023] According to Figure 1 , Figure 3 andFigure 4 As shown in the figure, one side of the upper end of the base 1 is provided with a drilling assembly 6 through a support frame 5, and the drilling assembly 6 is located directly above the middle of the flange body 405. The drilling assembly 6 includes a mounting frame 601, a lifting and moving assembly, a drilling motor 608 and a drill bit 609. A lifting and moving assembly is arranged inside the mounting frame 601. One lower end of the lifting and moving assembly is connected to the drilling motor 608. At the same time, the output end of the drilling motor 608 passes through an opening formed at the bottom of the mounting frame 601 and is connected to the drill bit 609. The drilling motor 608 and the drill bit 609 form a lifting structure with the mounting frame 601 through the lifting and moving assembly. The lifting and moving assembly drives the drilling motor 608 and the drill bit 609 to move downward, so that the drill bit 609 fits the drilling position of the flange body 405. Then, the drilling motor 608 is started to drive the drill bit 609 to rotate, which is convenient for drilling the flange body 405.

[0024] Specifically, the lifting and moving assembly includes a driving motor 602. The output end of the driving motor 602 is connected to a ball screw 603. A ball nut seat 604 is arranged on the ball screw 603. At the same time, one side of the ball nut seat 604 is connected to a linear guide rail 605 arranged on one side inside the mounting frame 601 through a connecting seat 606. An installation rod 607 is arranged on the connecting seat 606. The bottom of the installation rod 607 is connected to the drilling motor 608. The driving motor 602 drives the ball screw 603 to rotate, so that the ball nut seat 604 drives the connecting seat 606 to slide on the linear guide rail 605, so that the installation rod 607 installed on the connecting seat 606 drives the drilling motor 608 and the drill bit 609 to move up and down as a whole.

[0025] During use, first place the flange body 405 on the upper end of the placing seat 404. Then start the electric push rod 403 to drive the placing seat 404 to move downward, so that the fixed bracket 406 arranged on the outer side of the placing seat 404 slides downward inside the groove 4011 until the fixed bracket 406 is clamped between the placing seat 404 and the limit frame 401, and the upper end of the fixed bracket 406 limits the outer side of the upper end of the flange body 405. Then, through the lifting and moving assembly, the drilling motor 608 and the drill bit 609 move downward to fit the drilling position of the flange body 405. Then, while starting the drilling motor 608 to drive the drill bit 609 to rotate and drill, the lifting and moving assembly continues to drive the drilling motor 608 and the drill bit 609 to move downward until the drill bit 609 penetrates the flange body 405, then the drilling process of the flange body 405 is completed. When drilling other positions of the flange body 405 is required, start the electric rotating seat 402 to drive the electric push rod 403, the placing seat 404 and the flange body 405 to rotate inside the limit frame 401, so that the drilling position and the drill bit 609 are in the same horizontal vertical plane. Then start the electric guide rail 2 to drive the moving slide 3 and the clamping assembly 4 to move horizontally as a whole, so as to move the drilling position directly below the drill bit 609, and then drill it.

[0026] The orientation or positional relationship indicated by terms such as "center", "longitudinal", "lateral", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings, and is only a simplified description for facilitating the description of the present utility model, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation to the protected content of the present utility model.

[0027] Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
