Description

Technical Field

[0001] This utility model relates to the field of bearing processing technology, specifically to a punching device for flanges. Background Technology

[0002] In the field of machining, especially when drilling disc-shaped workpieces such as flanges and discs, workpiece fixation is crucial. Traditional single-station machining is inefficient, and most equipment requires manual adjustment of the flange position. Each hole needs to be machined and the workpiece must be re-clamped, which is time-consuming.

[0003] Common hydraulic clamping devices on the market are not compatible with flanges of different diameters, and changing the clamps increases downtime.

[0004] Traditional clamps use unidirectional clamping, which can easily cause flange misalignment and hole position deviation. To address these issues, we propose a flange drilling device. Utility Model Content

[0005] In view of the shortcomings of the prior art, this utility model provides a punching device for flanges to solve the above-mentioned problems in the prior art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A flange punching device includes a base plate, a frame and a support frame on the base plate, a punching assembly on the support frame, a rotating platform at the center of the frame, the rotating platform being embedded in the base plate, a support rod on the rotating platform, a lifting cylinder inside the support rod, at least four guide frames at the end of the support rod, a tray on each guide frame, a toothed disc on the outer edge of the tray, and the toothed disc being mounted on the four guide frames.

[0008] The gear plate is slidably engaged with the guide frame, and a connecting rod is hinged between the tray and the piston rod end of the lifting cylinder. Multiple limiting rods for tensioning the flange are provided above the tray.

[0009] The gear plate is equipped with at least two telescopic cylinders, and each telescopic cylinder has at least two freely rotatable rocker arms at the piston rod end, which are used to press the flange.

[0010] Furthermore, the support frame is provided with a moving platform for horizontally moving the drilling assembly, the moving platform moving in the direction of the flange axis, and the support frame is also provided with an adjusting screw for adjusting the position of the drilling assembly on the flange.

[0011] Furthermore, the drilling assembly includes a telescopic rod movably mounted on a mobile platform, a first motor mounted on the mobile platform and driving the telescopic rod to rotate, a drill bit provided at the end of the telescopic rod near the flange, and a lifting part for adjusting the length of the telescopic rod provided at the bottom of the mobile platform.

[0012] Furthermore, the four guide frames extend horizontally in four directions respectively, and the tray is fan-shaped; the tray moves along the slide grooves provided on the guide frames.

[0013] Furthermore, a gap is left between the tray and the toothed disc to facilitate the movement of the tray and the drilling of the flange by the drill bit; the toothed disc meshes with the output gear of the second motor mounted on the frame to drive the toothed disc to rotate.

[0014] Furthermore, the gear plate is detachably connected to the guide frame, and the support rod has a through hole at the connection between the connecting rod and the lifting cylinder; the through hole is used to restrict the movement direction of the connecting rod.

[0015] Furthermore, the flange is vertically mounted on the pallet. When the flange is placed on the pallet, the flange applies pressure to the limiting rod, causing the limiting rod to be hidden inside the pallet; when no flange is placed, the limiting rod pops out.

[0016] Furthermore, the frame is provided with a U-shaped hole at the position where the telescopic cylinder is installed. The U-shaped hole is used to fix the telescopic cylinder and its position on the frame can be adjusted by adjusting bolts. The swing rod is connected to the end of the piston rod of the telescopic cylinder by a pin and can rotate freely around the piston rod.

[0017] This utility model provides a punching device for flanges. It has the following advantages: a second motor drives a gear disc to rotate, which in turn drives four sector-shaped pallets to rotate synchronously through gear meshing; the four pallets are raised and lowered by lifting cylinders, creating different angles between the connecting rod and the pallets, causing the pallets to move along the guide frame direction; the through holes in the support rods restrict the direction of movement of the connecting rods, eliminating radial sway during the raising and lowering process; it realizes a streamlined operation of "clamping-drilling-unloading"; the rotating table is embedded in the base plate, ensuring no axial offset when the sector-shaped pallets rotate.

[0018] The swing arm rotates freely via a pin, avoiding the drilled holes on the flange. The telescopic cylinder pushes the swing arm to apply pressure to the flange, causing it to fit against the pallet. The telescopic cylinder can be moved via a U-shaped hole and adjusting bolts to accommodate flanges of different diameters.

[0019] The limiting rod applies radial pressure to the side wall of the flange inner diameter as the pallet moves. When subjected to axial pressure, the limiting rod retracts into the pallet, and when not subjected to pressure, the spring returns and ejects the limiting rod.

[0020] The gap between the toothed disc and the tray can be adjusted according to the drilling position of the flange to avoid interfering with the drill bit operation. Attached Figure Description

Detailed Implementation

[0028] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0029] See attached document Figures 1-6 A punching device for a flange 100 includes a base plate 1, a frame 13 and a support frame 2 on the base plate 1, a punching assembly 3 on the support frame 2, a rotating platform 12 at the center of the frame 13, the rotating platform 12 being embedded in the base plate 1, a support rod 6 on the rotating platform 12, a lifting cylinder 7 inside the support rod 6, at least four guide frames 10 at the end of the support rod 6, a tray 9 on each guide frame 10, a toothed disc 4 on the outer edge of the tray 9, and the toothed disc 4 being mounted on the four guide frames 10.

[0030] The gear plate 4 is slidably engaged with the guide frame 10, and a connecting rod 8 is hinged between the tray 9 and the piston rod end of the lifting cylinder 7. Multiple limiting rods 91 for tensioning the flange 100 are provided above the tray 9.

[0031] The gear plate 4 is provided with at least two telescopic cylinders 5, and the piston rod end of each telescopic cylinder 5 is provided with at least two freely rotatable rocker arms 51, which are used to press the flange 100.

[0032] Specifically, the base plate 1 serves as the basic platform of the device, bearing the loads of all components such as the frame 13 and the support frame 2; the frame 13 provides a rigid support structure, with the rotary table 12 installed in the center, and the support frame 2 bears the axial cutting force during drilling; the rotary table 12 is embedded in the center of the base plate 1, and the built-in bearing enables 360° rotation.

[0033] The support frame 2 is provided with a moving platform 22 for horizontally moving the drilling assembly 3. The moving platform 22 moves in the axial direction of the flange 100. The support frame 2 is also provided with an adjusting screw 21 for adjusting the position of the drilling assembly 3 on the flange 100.

[0034] The drilling assembly 3 includes a telescopic rod movably mounted on the mobile platform 22, a first motor mounted on the mobile platform 22 and driving the telescopic rod to rotate, a drill bit provided at the end of the telescopic rod near the flange 100, and a lifting part 23 for adjusting the length of the telescopic rod provided at the bottom of the mobile platform 22.

[0035] The four guide frames 10 extend horizontally in four directions respectively, and the tray 9 is fan-shaped; the tray 9 moves along the slide grooves provided on the guide frames 10.

[0036] Specifically, the guide frame 10 is arranged radially in four directions, and the internal T-shaped groove guides the tray 9 to move radially;

[0037] A gap is left between the tray 9 and the toothed disc 4 to facilitate the movement of the tray 9 and the drilling of the flange 100 by the drill bit; the toothed disc 4 meshes with the output gear of the second motor 11 mounted on the frame 13 to drive the toothed disc 4 to rotate.

[0038] Specifically, the gear 4 meshes with the gear of the second motor 11, driving the four trays 9 to rotate synchronously;

[0039] The gear plate 4 is detachably connected to the guide frame 10, and the support rod 6 has a through hole 61 at the connection between the connecting rod 8 and the lifting cylinder 7; the through hole 61 is used to limit the movement direction of the connecting rod 8.

[0040] The flange 100 is vertically mounted on the tray 9. When the flange 100 is placed on the tray 9, the flange 100 applies pressure to the limiting rod 91, causing the limiting rod 91 to be hidden inside the tray 9. When the flange 100 is not placed, the limiting rod 91 pops out.

[0041] Specifically, the limit rod 91 has a spring reset structure, which is compressed back into the tray 9, and the pop-out height is adjustable;

[0042] The frame 13 has a U-shaped hole at the position where the telescopic cylinder 5 is installed. The U-shaped hole is used to fix the telescopic cylinder 5 and its position on the frame 13 can be adjusted by adjusting bolts. The swing rod 51 is connected to the end of the piston rod of the telescopic cylinder 5 by a pin and can rotate freely around the piston rod.

[0043] Working principle: When the workpiece is clamped, the lifting cylinder 7 retracts the four sector trays 9 to the end of the guide frame 10 through the connecting rod 8. At this time, the limit rod 91 is in the pop-out state due to the action of the spring.

[0044] The operator places flange 100 vertically into pallet 9, and the edge of flange 100 presses against limiting rod 91 to retract it into pallet 9.

[0045] The lifting cylinder 7 drives four sector-shaped trays 9 through the connecting rod 8 to ensure the radial positioning of the trays 9 in the T-shaped slide groove of the guide frame 10, and makes the limiting rod 91 contact the inner diameter wall of the flange 100 to achieve the clamping of the flange 100 and ensure that the center of the workpiece is aligned with the axis of the rotary table 12.

[0046] After clamping is completed, rotate the rocker arm 51 to cover the flange 100 and avoid the drilling position, and the telescopic cylinder 5 will press the rotated rocker arm 51 to press the flange 100.

[0047] During drilling, the lead screw 21 controls the horizontal displacement of the moving platform 22, and the lifting unit 23 adjusts the length of the telescopic rod to ensure that the drill bit is precisely aligned with the drilling position on the flange 100.

[0048] The first motor drives the drill bit to rotate, and the moving platform 22 propels the drill bit to complete radial feed.

[0049] After a single hole is machined, the second motor 11 meshes with the gear plate 4 through its output gear, driving the four trays 9 to rotate synchronously. The gear plate 4 automatically rotates to the next drilling station, and the rotary table 12 achieves smooth rotation through embedded bearings.

[0050] When the workpiece is unloaded, the telescopic cylinder 5 retracts the swing arm 51, and the lifting cylinder 7 lifts the pallet 9 so that the flange 100 is disengaged from the limit rod 91, thus completing the removal of the workpiece.

[0051] During quick model changeover, the position of telescopic cylinder 5 can be adjusted using the U-shaped hole adjusting bolt to adapt to the new specification flange 100.
