Description

Technical Field

[0001] This utility model relates to the field of machining technology, specifically a flange oblique hole machining device. Background Technology

[0002] During the production and processing of workpieces, drilling operations are required. Common vertical or horizontal drilling can be completed on ordinary machining lathes. However, if angled holes need to be drilled on the workpiece, the workpiece needs to be positioned or the position of the drilling equipment adjusted to determine the appropriate angle.

[0003] Existing inclined drilling methods are problematic for workpieces, such as large flanges. Due to their large size, the positioning accuracy requirements for drilling are extremely high. If the positioning is inaccurate, the drilling position may deviate, affecting subsequent assembly and use. Adjusting the position of large flanges is also difficult, as the flange's position needs to be adjusted according to different drilling positions, leading to reduced drilling efficiency. In addition, large flanges may move during drilling, so it is necessary to ensure the stability of the large flange in the drilling position. Precise angle control is required when drilling at 45 degrees. If the angle control is inaccurate, the drilling slope may not meet the requirements, affecting the use of the flange. Utility Model Content

[0006] An electric cylinder is located above the gear plate, and a sliding rod is slidably fitted below the gear plate. The output shaft of the electric cylinder passes through a through hole in the gear plate and is connected to one end of the sliding rod.

[0007] The other end of the slide rod and the gear plate are provided with a first link and a second link that are movably connected to each other.

[0008] The second connecting rod has a guide groove on one side, and a rack is slidably fitted in the guide groove. The guide groove has an opening.

[0011] In a further embodiment, the ring is fixedly connected to four sleeves, and the toothed disc can rotate about the axis of the ring.

[0012] In a further embodiment, the drilling rig is connected to the pin hole threadedly via a U-shaped bracket.

[0015] Beneficial effects: This utility model discloses a flange oblique hole processing device.

[0016] The electric cylinder pushes the slide rod, which converts the linear motion into the tilting motion of the drill through the first and second connecting rods, directly controlling the drilling angle of the drill. It works in conjunction with the rotation of the gear plate to achieve multi-angle inclined hole processing. The suction cup in the center of the base plate adsorbs and fixes large flanges to prevent them from shifting during processing.

Detailed Implementation

[0029] This utility model provides a flange oblique hole machining device that solves the problems of angle deviation, positioning difficulty, and poor stability in large flange oblique hole machining through the coordinated operation of electric cylinder-connecting rod angle control, gear plate rotation positioning, suction cup fixing, and rack radial adjustment. The specific implementation of the solution is described below through specific embodiments.

[0030] Reference Figures 1-10 As shown, a flange bevel hole machining device includes:

[0031] A base plate 1 is provided with a suction cup 11 for adsorbing the flange 100 at its center. The suction cup 11 is located in the area surrounding four lifting cylinders 2. At least four lifting cylinders 2 are provided above the base plate 1. Sleeves 3 are sleeved on the output shafts of the four lifting cylinders 2. A ring 43 is fixedly connected above the four sleeves 3. A gear disk 4 is slidably fitted above the ring 43. A second motor 21 is provided on the outer side of one of the four sleeves 3. The drive gear shaft of the second motor 21 meshes with the outer edge teeth of the gear disk 4. An auxiliary gear 47 is provided on the outer side of another adjacent sleeve 3. The auxiliary gear 47 meshes with the outer edge teeth of the gear disk 4. The ring 43 is fixedly connected to the four sleeves 3. The gear disk 4 can rotate around the axis of the ring 43.

[0032] An electric cylinder 42 is provided above the gear disk 4, and a slide rod 44 is slidably fitted below the gear disk 4. The output shaft of the electric cylinder 42 passes through a through hole 41 in the gear disk 4 and is connected to one end of the slide rod 44. A first connecting rod 46 and a second connecting rod 45 are provided between the other end of the slide rod 44 and the gear disk 4, which are movably connected to each other. The other end of the slide rod 44 is movably connected to the first connecting rod 46, and the first connecting rod 46 is movably connected to the second connecting rod 45. The gear disk 4 is movably connected to the second connecting rod 45.

[0033] The second connecting rod 45 has a guide groove 51 on one side, and the mounting base of the guide groove 51 is fixed to the second connecting rod 45 by screws; a rack 53 is slidably fitted in the guide groove 51, and the guide groove 51 has an opening 52; the second connecting rod 45 is equipped with a first motor 451, and the output gear of the first motor 451 extends into the second connecting rod 45, and the output gear of the first motor 451 meshes with the rack 53 through the opening 52; the rack 53 has multiple sets of pin holes 531 for fixing the drilling rig 101; the drilling rig 101 is threadedly connected to the pin holes 531 through a U-shaped bracket.

[0034] Working principle description: Place the flange 100 to be processed on the suction cup 11 at the center of the base plate 1, start the suction cup 11, and use negative pressure to adsorb and fix the flange 100 to ensure that the flange 100 will not move during the processing.

[0035] Start the four lifting cylinders 2. The output shaft of the cylinder drives the sleeve 3 to move up and down, thereby adjusting the height of the ring 43 fixedly connected to the sleeve 3. Since the gear plate 4 slides above the ring 43, the height of the gear plate 4 is also adjusted to adapt to flanges 100 of different thicknesses or different drilling depth requirements.

[0036] The drive gear of the second motor 21 (installed on the outside of one of the sleeves 3) meshes with the outer edge teeth of the gear disk 4. After the second motor 21 is started, it drives the gear disk 4 to rotate around the axis of the ring 43. The auxiliary gear 47 on the outside of the other adjacent sleeve 3 also meshes with the gear disk 4 to ensure the stability of the gear disk 4 when it rotates and avoids swaying.

[0037] By controlling the rotation angle of the second motor 21, the position of the gear plate 4 and the drill 101 mounted on the rack 53 in the circumferential direction of the flange 100 can be adjusted to realize the processing of inclined holes at different angles.

[0038] When the electric cylinder 42 extends or retracts, it drives the slide rod 44 to slide along the bottom of the gear plate 4. When the slide rod 44 is pushed by the electric cylinder 42, it drives the rack 53 to slide in the guide groove 51 through the linkage of the first connecting rod 46 and the second connecting rod 45, thereby changing the tilt angle of the drill 101 fixed on the rack 53.

[0039] The output gear of the first motor 451 meshes with the rack 53. When the motor rotates forward and backward, the rack 53 moves back and forth along the guide groove 51, driving the drilling rig 101 to approach or move away from the flange 100.

[0040] After adjusting the rotation angle (circumferential position) of the gear disc 4 and the tilt angle of the drill 101, start the first motor 451, so that the rack 53 drives the drill 101 to move (feed) towards the flange 100; the drill 101 contacts the flange 100 and starts drilling, and the drilling depth is controlled by the moving distance of the rack 53; after drilling is completed, the first motor 451 reverses and the drill 101 retracts.

[0041] The preferred embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the specific details of the above embodiments. Within the scope of the technical concept of the present invention, various equivalent transformations can be made to the technical solutions of the present invention, and all such equivalent transformations fall within the protection scope of the present invention.
