[0001] This utility model relates to the field of flange processing technology, and in particular to a drilling device for flange processing. Background Technology

[0002] A flange, also called a flange plate or flange, is a commonly used connecting component in mechanical engineering. It is used to connect equipment such as pipes, valves, pumps, and containers, enabling them to achieve a sealed connection and force transmission. A flange drilling device is a piece of equipment used to drill holes in flanges.

[0003] A search revealed that the document with publication number "CN221910890U" mentions "This utility model discloses a flange drilling machine, belonging to the field of flange processing technology, including a base, a chuck on the base, movable jaws arranged in a circumferential array on the chuck, the movable jaws sliding radially along the chuck, a jaw drive mechanism inside the chuck for driving the movable jaws to slide radially along the chuck to clamp or open, an adjustable drilling mechanism on one side of the base, and the movable jaws including a moving block, a transverse sliding side clamping plate, and a follower connecting rod. Specifically, this utility model provides a flange drilling machine for..." The flange is clamped and fixed in multiple directions to improve stability during drilling. It utilizes a follower rod and spring to achieve linkage between the horizontal sliding side clamp and the vertical sliding upper clamp. With only one drive, the flange can be clamped and fixed simultaneously in both horizontal and vertical directions, thus achieving precise clamping and positioning of the flange during drilling. However, this device provides bottom support by directly contacting the workpiece with the chuck, without leaving sufficient bottom space. During drilling, the drill bit penetrating the workpiece is prone to contact with the chuck, leading to additional wear on the drill bit and damage to the chuck. Furthermore, debris cannot be removed from the bottom, and the resulting blockage can affect machining accuracy.

[0004] To address these issues, we provide a drilling device for flange machining. Utility Model Content

[0005] The purpose of this invention is to provide a drilling device for flange processing, thereby solving the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a drilling device for flange processing, comprising a base and a clamping assembly, wherein the clamping assembly is installed on one side of the top of the base, the clamping assembly includes an indexing plate installed on one side of the top of the base, a support plate is installed on the top of the indexing plate, a rotating shaft is rotatably connected to the inner side of the support plate, and a first motor is connected to the bottom of the rotating shaft with a flat key.

[0007] Preferably, a drive gear is fixedly connected to the surface of the rotating shaft, a transmission gear is meshed with the outer side of the drive gear, a first screw is fixedly connected to the inner side of the transmission gear, and a limit rod is rotatably connected to one side of the surface of the first screw through a slot.

[0008] Preferably, a movable block is threadedly connected to the other side of the surface of the first screw, and a sliding frame is slidably connected to the outer side of the movable block through a slot, with one end of the sliding frame fixedly connected to the support platform.

[0009] Preferably, an arc-shaped bracket is fixedly connected to the top of the movable block, and a second screw is rotatably connected to the inner side of the arc-shaped bracket through a slot. A second motor is connected to the top of the second screw via a flat key.

[0011] Preferably, a limiting frame is fixedly connected to the other side of the top of the base, a support frame is slidably connected to the inner side of the limiting frame through a slot, and a first electric telescopic rod is installed on one side of the bottom of the support frame.

The connecting plate and the support frame form a sliding structure through a slot, and a drilling rig is installed at one end of the connecting plate.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. An auxiliary clamping structure is provided by the clamping assembly to clamp the outer side of the workpiece, leaving space at the bottom to prevent the drill bit from colliding and damaging other components after penetrating the workpiece. This facilitates the removal of debris from the bottom and reduces the possibility of blockage. The first motor provides power to drive the rotating shaft to rotate, which in turn drives the three sets of transmission gears to rotate. This causes the first screw to rotate and move the moving block to slide on the sliding frame, thereby adjusting the horizontal position of the three sets of arc-shaped brackets and changing the clamping range. After the workpiece is placed on the anti-slip pad on the surface of the arc-shaped bracket and clamped, the second motor provides power to drive the upper clamping plate to move vertically within the slot of the arc-shaped bracket. This causes the anti-slip pad at the bottom of the upper clamping plate to abut against the top of the workpiece, ensuring the stability of the workpiece clamping in the vertical direction. At this time, only the edges of the workpiece are clamped and fixed, and there is sufficient space at the bottom.

[0015] 2. The first electric telescopic rod extends and retracts to move the support frame horizontally within the slot of the limit frame, changing the horizontal position of the drilling rig. The second electric telescopic rod extends and retracts to move the connecting plate vertically within the slot of the support frame, changing the vertical position of the drilling rig. The drilling rig then contacts the workpiece and performs drilling. The rotation angle of the support table is precisely adjusted by the indexing plate to improve drilling accuracy.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-4 As shown, a drilling device for flange processing includes a base 1 and a clamping assembly 2. The clamping assembly 2 is installed on one side of the top of the base 1. The clamping assembly 2 includes an indexing plate 201 installed on one side of the top of the base 1. A support platform 202 is installed on the top of the indexing plate 201. A rotating shaft 203 is rotatably connected to the inner side of the support platform 202. A first motor 204 is connected to the bottom of the rotating shaft 203 by a flat key.

[0023] Furthermore, a drive gear 205 is fixedly connected to the surface of the rotating shaft 203. A transmission gear 206 is meshed with the outer side of the drive gear 205. A first screw 207 is fixedly connected to the inner side of the transmission gear 206. A limit rod 208 is rotatably connected to one side of the surface of the first screw 207 through a slot. The first motor 204 provides power to drive the rotating shaft 203 to rotate, so that the drive gear 205 drives the three sets of transmission gears 206 to rotate. The limit rod 208 provides limitation and support for the first screw 207.

[0024] Furthermore, a movable block 209 is threadedly connected to the other side of the surface of the first screw 207. A sliding frame 210 is slidably connected to the outer side of the movable block 209 through a slot. One end of the sliding frame 210 is fixedly connected to the support 202. The three sets of first screws 207 can be designed to make the three sets of movable blocks 209 move synchronously along their respective connected sliding frames 210 towards or away from the center of the support 202, thereby adjusting the clamping range.

[0025] Furthermore, an arc-shaped bracket 211 is fixedly connected to the top of the movable block 209. A second screw 212 is rotatably connected to the inner side of the arc-shaped bracket 211 through a slot. A second motor 213 is connected to the top of the second screw 212 via a flat key. The second motor 213 provides power to drive the upper clamping plate 214 to move vertically within the slot of the arc-shaped bracket 211.

[0026] Furthermore, the surface of the second screw 212 is threaded with an upper clamping plate 214. The upper clamping plate 214 and the arc-shaped bracket 211 form a sliding structure through a slot. The anti-slip pad at the bottom of the upper clamping plate 214 abuts against the top of the workpiece to ensure the stability of the workpiece in the vertical direction. At this time, only the edge of the workpiece is clamped and fixed, and there is enough space at the bottom.

[0027] Furthermore, a limiting frame 3 is fixedly connected to the other side of the top of the base 1. A support frame 4 is slidably connected to the inner side of the limiting frame 3 through a slot. A first electric telescopic rod 5 is installed on one side of the bottom end of the support frame 4. The horizontal movement of the support frame 4 within the slot of the limiting frame 3 is changed by extending and retracting the first electric telescopic rod 5.

The drilling machine 8 then contacts the workpiece and performs drilling.

[0029] Working principle: In use, firstly, the first motor 204 provides power to drive the rotating shaft 203 to rotate, causing the drive gear 205 to drive the three sets of transmission gears 206 to rotate, causing the first screw 207 to rotate and drive the moving block 209 to slide on the sliding frame 210, thereby adjusting the horizontal position of the three sets of arc-shaped brackets 211, changing the clamping range, and placing the workpiece on the anti-slip pad on the surface of the arc-shaped bracket 211 and clamping it. Secondly, the second motor 213 provides power to drive the upper clamping plate 214 to move vertically within the slot of the arc-shaped bracket 211, so that the anti-slip pad at the bottom of the upper clamping plate 214 abuts against the top of the workpiece. To ensure the stability of the workpiece in the vertical direction, at this point only the edges of the workpiece are clamped and fixed, and there is sufficient space at the bottom, the third step is to move the support frame 4 horizontally within the slot of the limit frame 3 by extending and retracting the first electric telescopic rod 5, thereby changing the horizontal position of the drill rig 8. The second electric telescopic rod 6 extends and retracts, causing the connecting plate 7 to move vertically within the slot of the support frame 4. The drill rig 8 then contacts the workpiece and performs drilling. The fourth step is to precisely adjust the rotation angle of the support table 202 through the indexing plate 201 to improve the drilling accuracy. The drill rig 8 then rises and falls to continue drilling the workpiece. This completes the use of a drilling device for flange processing.
