Description

Technical Field

[0001] This utility model relates to the field of drilling equipment, and in particular to a high-speed dual-head automatic drilling device. Background Technology

[0002] With the continuous development of technology, the processing precision of mechanical components is getting higher and higher. Depending on the assembly needs of the workpiece, it is often necessary to drill or tap tubular components.

[0003] Traditionally, tubular workpieces are manually placed on a fixture, which clamps the outer wall of the workpiece. Then, a high-speed rotating drill bit is used to drill holes at both ends of the workpiece. The waste generated during drilling pollutes the working environment. When unloading, after drilling is completed, the drill bit leaves the workpiece, and the operator has to release the fixture from the workpiece before removing it. The operation is cumbersome and the overall drilling efficiency of the workpiece is low. Utility Model Content

The piston rod of the first pushing cylinder is fixed to the first clamping block, and the piston rod of the second pushing cylinder is fixed to the second clamping block.

[0011] After the piston rod of the second push cylinder extends, the second clamping block moves toward the first clamping block and cooperates with the first clamping block to clamp the workpiece;

[0012] The piston rod of the first pushing cylinder extends and the piston rod of the second pushing cylinder retracts. The first clamping block and the second clamping block move synchronously, driving the workpiece to move between the two drilling heads and set coaxially with the two drilling heads.

[0016] The support plate raises the placement plate so that the central axis of the workpiece and the central axis of the drilling head are on the same horizontal plane.

[0017] Preferably, the first clamping block and the second clamping block have an arc-shaped groove on their sides that are close to each other, which is used to accommodate the workpiece.

The output shaft of the drive motor rotates synchronously with the auger. A waste discharge port is opened on the bottom wall of the receiving frame at the end away from the clearance port along its length. The rotation of the auger drives some waste chips to move away from the clearance port.

[0020] The waste collection frame is located below the receiving frame and directly below the clearance opening. The receiving frame has several chip discharge gaps above the waste collection frame for chip dropping.

[0035] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0036] This application discloses a high-speed dual-head automatic drilling device.

[0037] Reference Figure 1-4 The high-speed dual-head automatic drilling equipment includes a worktable 1, on which a clamping mechanism 2, a drilling mechanism 3, and a feeding mechanism 4 are provided. The clamping mechanism 2 is used to clamp the workpiece, the drilling mechanism 3 drills holes at both ends of the workpiece simultaneously, and the feeding mechanism 4 is used to separate the waste chips from the workpiece.

[0038] The clamping mechanism 2 includes a placement plate 21, a first clamping block 22, a second clamping block 23, a first pushing cylinder 24, and a second pushing cylinder 25. The placement plate 21 is fixedly mounted on the worktable 1 via a support plate 211. The placement plate 21 is horizontally positioned and located between the first clamping block 22 and the drilling mechanism 3. The first clamping block 22 and the second clamping block 23 are slidably mounted on both sides of the radial direction of the drilling head 31. The first pushing cylinder 24 and the second pushing cylinder 25 are both fixed on the worktable 1. The piston rod of the first pushing cylinder 24 is fixed to the first clamping block 22, and the piston rod of the second pushing cylinder 25 is fixed to the second clamping block 23.

[0039] The first clamping block 22 and the second clamping block 23 have arc-shaped grooves on their sides that are close to each other, which are used to accommodate the workpiece. The inner arc surface of the arc-shaped groove fits against the outer circumferential surface of the workpiece, thereby improving the fit between the first clamping block 22 and the second clamping block 23 and the workpiece.

[0040] After the piston rod of the second push cylinder 25 extends, the second clamping block 23 moves toward the first clamping block 22 and cooperates with the first clamping block 22 to clamp the workpiece. The piston rod of the first push cylinder 24 extends and the piston rod of the second push cylinder 25 retracts. The first clamping block 22 and the second clamping block 23 move synchronously, driving the workpiece to move between the two drilling heads 31 and set coaxially with the two drilling heads 31.

[0041] The drilling mechanism 3 includes two coaxially arranged drilling cutter heads 31. The ends of the drilling cutter heads 31 that are far apart from each other are connected to a rotating shaft 32. The rotating shaft 32 rotates through a rotating assembly.

[0042] The rotating assembly includes a rotating motor 33, a power head 34, and a coupling 35. The output end of the rotating motor 33 is coaxially connected to the input end of the power head 34, and the output end of the power head 34 is coaxially connected to the rotating shaft 32 through the coupling 35.

[0043] The power head 34 slides through the lead screw module 36. The output end of the power head 34 and the lead screw module 36 are fixed. The two power heads 34 move toward each other or away from each other through the corresponding lead screw modules 36.

[0044] The support plate 211 raises the placement plate 21 so that the central axis of the workpiece and the central axis of the drilling head 31 are on the same horizontal plane.

[0045] The workbench 1 has a clearance opening 11 located below the drilling head 31, and the workbench 1 is hollow inside.

[0046] The feeding mechanism 4 includes a receiving frame 41, a waste collection frame 42, a discharge frame 43, a tilting plate 44, and a collection frame 45. The receiving frame 41 is set inside the workbench 1 and fixed to the inner wall of the workbench 1. One end of the receiving frame 41 extends out of the workbench 1. An auger 411 is rotatably installed inside the receiving frame 41. A drive motor 412 is installed at one end of the receiving frame 41. The output shaft of the drive motor 412 and the auger 411 rotate synchronously through a sprocket and chain transmission structure. A sprocket 1 is coaxially connected to the output shaft of the drive motor 412, and a sprocket 2 is coaxially connected to the auger 411. The chain is wound around both sprocket 1 and sprocket 2 and meshes with both sprocket 1 and sprocket 2. Since the sprocket and chain transmission structure is a conventional technical means, it will not be shown in the attached drawings.

[0047] The bottom wall of the receiving frame 41, which is away from the relief opening 11 along its length, has a waste discharge port 413. The auger 411 rotates and drives some of the waste chips to move away from the relief opening 11.

[0048] The waste collection frame 42 is located below the receiving frame 41, and directly below the clearance opening 11. A support frame 421 is located below the waste collection frame 42, and the support frame 421 is fixed inside the workbench 1. The waste collection frame 42 is fixed to the top surface of the support frame 421. Several chip discharge gaps 414 are provided in the receiving frame 41 directly above the waste collection frame 42 for waste chips to fall into.

[0049] Larger waste chips are discharged from the waste discharge port 413 via the auger 411, while smaller waste chips cannot be carried by the auger 411 and therefore fall directly into the waste collection frame 42 through the chip discharge gap 414.

[0050] The unloading frame 43 is located diagonally below the receiving frame 41. The bottom wall of the unloading frame 43 is fixed to the workbench 1 by a fixing plate 431. The unloading frame 43 is set at an angle. The end of the unloading frame 43 away from the receiving frame 41 is the lowest end of the unloading frame 43. The side wall of the receiving frame 41 is provided with an unloading port 415 for the workpiece to fall from the receiving frame 41 into the unloading frame 43.

[0051] The tilting plate 44 is located between the receiving frame 41 and the unloading frame 43. The tilting plate 44 includes an upper plate 441 and a lower plate 442 and is L-shaped. There is a tilting shaft 443 between the upper plate 441 and the lower plate 442. The tilting shaft 443 is reciprocated by the tilting component 46. The length of the upper plate 441 is greater than the length of the lower plate 442. The highest end of the unloading frame 43 is connected to the tilting shaft 443. The collecting frame 45 is located on the ground. The workpiece falls into the collecting frame 45 along the unloading frame 43.

[0052] When the workpiece needs to be unloaded, the flipping shaft 443 rotates until the side of the upper plate 441 away from the lower plate 442 is below the workpiece. At this time, the upper plate 441 blocks the clearance opening 11, and the workpiece falls onto the side of the upper plate 441 away from the lower plate 442. After the flipping shaft 443 rotates in the opposite direction, it flips the workpiece onto the unloading frame 43.

[0053] The flipping assembly 46 includes a telescopic cylinder 461 and a connecting rod 462. A fixed frame 463 is provided on the inner bottom wall of the worktable 1. The cylinder body of the telescopic cylinder 461 is hinged to the fixed frame 463. The piston rod of the telescopic cylinder 461 is hinged to one end of the connecting rod 462. The other end of the connecting rod 462 is fixedly connected to the flipping shaft 443.

[0054] A limiting plate 464 is fixed on the inner top wall of the workbench 1. The limiting plate 464 has a limiting hole for the flipping shaft 443 to pass through. The flipping shaft 443 rotates in the limiting hole. The fixing plate 431 is fixedly connected between the two limiting plates 464. The bottom wall of the unloading frame 43 is fixedly connected to the top surface of the fixing plate 431 through a connecting plate.

[0055] The implementation principle of a high-speed dual-head automatic drilling device according to an embodiment of this application is as follows:

[0056] After the worker places the workpiece on the placement plate 21, the clamping mechanism 2 moves the workpiece to the drilling mechanism 3. Then, the two drilling heads 31 rotate at high speed and move towards each other, drilling the workpiece synchronously at both ends. After drilling is completed, the flipping plate 44 rotates until the upper plate 441 is below the workpiece. Then, the drilling heads 31 leave the workpiece, and the first clamping block 22 and the second clamping block 23 also leave the workpiece. The workpiece falls onto the receiving frame 41 and is finally moved by the flipping plate 44 to the unloading frame 43 and slides along the unloading frame 43 into the receiving frame. The automation is high, the operation is convenient, and the drilling efficiency of the workpiece is improved.

[0057] During the drilling process, waste chips fall into the receiving frame 41. Larger waste chips are discharged from the waste discharge port 413 through the auger 411, while smaller waste chips fall directly into the waste collection frame 42 through the chip discharge gap 414, so as to separate waste chips from workpieces and reduce pollution to the working environment.

[0058] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
