DETAILED DESCRIPTION

[0031] In order to make the purpose, technical scheme and advantages of the embodiments of the present application more clear, the technical scheme in the embodiments of the present application is described clearly and completely. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0032] Embodiment one

[0033] To solve the technical problems in the background art, a disc metal piece drilling positioning device is given as follows:

[0034] In combination with Figures 1-4 the drawings, the present application provides a disc metal piece drilling positioning device, which comprises:

[0035] The fixed plate 1 is fixedly installed on the drilling machine base 2, the waste groove 21 is formed in the top of the drilling machine base 2, the displacement mechanism 22 is installed on the top of the drilling machine base 2, the movable end of the displacement mechanism 22 is fixedly installed with the mounting frame 23, the drill bit 24 in vertical shape is rotatably installed on the mounting frame 23, and it is specifically pointed out that: the displacement mechanism 22 comprises a vertical plate which is slidingly installed on the drilling machine base 2 in a horizontal direction, the vertical plate is fixedly provided with two telescopic rods one in a horizontal shape at the top position in a symmetrical manner, the end portions of the two telescopic rods one are fixedly connected with a connecting block, the vertical plate is fixedly provided with an electric cylinder one connected with the connecting block, the connecting block is fixedly provided with two telescopic rods two in a vertical shape in a symmetrical manner, the mounting frame 23 is fixedly connected with the end portions of the two telescopic rods two, the connecting block is fixedly installed with an electric cylinder two connected with the mounting frame 23, and the mounting frame 23 is fixedly installed with a driving motor for driving the drill bit 24 to rotate;

[0036] The rotating shaft 3 is rotatably installed on the fixed plate 1 in a vertical direction, and the mounting seat 31 is integrally formed at the top of the rotating shaft 3.

[0037] The drive mechanism 4 is mounted on the fixed plate 1 and connected to the rotating shaft 3. The drive mechanism 4 is used to make the rotating shaft 3 rotate or stop rotating on the fixed plate 1.

[0038] There are two connecting plates 32, which are symmetrically installed on the top of the mounting base 31. The ends of the connecting plates 32 can extend above the waste trough 21. A vertical rotating shaft 33 is rotatably installed on the end of the connecting plate 32. A positioning mechanism 5 is installed on the top of the rotating shaft 33. A flange 6 is sleeved on the outside of the positioning mechanism 5. The positioning mechanism 5 is used to position the flange 6. A motor 34 for driving the rotating shaft 33 to rotate is fixedly installed on the connecting plate 32.

[0039] In use, the flange 6 is fitted onto the outside of the positioning mechanism 5, which positions the flange 6. Then, the drive mechanism 4 rotates the shaft 3 on the fixed plate 1, positioning the flange 6 above the waste trough 21. At this point, the displacement mechanism 22 moves the mounting frame 23, causing the drill bit 24 to contact the flange 6. The drill bit 24 then rotates, drilling a hole in the flange 6. With two connecting plates 32 and another positioning mechanism 5 located outside the drilling machine base 2, the operator can load the flange 6 onto the positioning mechanism 5 outside the drilling machine base 2. After drilling the flange 6 above the waste trough 21, the drive mechanism 4 rotates the shaft 3 on the fixed plate 1, moving the finished flange 6 to the outside of the drilling machine base 2. The flange 6 to be processed on the outside of the base 2 can be rotated to the bottom of the drill bit 24. At this time, the flange 6 to be processed can be drilled. The operator can unload the flange 6 located on the outside of the drilling base 2 and replace it with the next flange 6 to be processed. This achieves the effect of loading the flange 6 to be processed while drilling the flange 6. When replacing the flange 6, the operator only needs to rotate the shaft 3 on the fixed plate 1 through the drive mechanism 4 to replace the flange 6. This greatly shortens the time required to replace the flange 6. It replaces the operation method of first positioning the flange 6 by the positioning mechanism 5, and then loading and positioning the flange 6 to be drilled after unloading the flange 6. This effectively avoids wasting time when replacing the flange 6, thereby improving the processing efficiency of the flange 6.

[0040] Example 2

[0041] like Figures 1-4 As shown, based on the above embodiments, this embodiment further provides the following:

[0042] In this embodiment, the drive mechanism 4 includes a motor 41 fixedly mounted on the bottom of the fixed plate 1. The output shaft of the motor 41 is connected to the rotating shaft 3 through a bevel gear assembly 42. Specifically, the bevel gear assembly 42 includes two meshing bevel gears. One bevel gear is coaxially fixed to the rotating shaft 3, and the other bevel gear is coaxially fixed to the output shaft of the motor 41. In use, the motor 41 is turned on, and the output shaft of the motor 41 rotates, which drives the rotating shaft 3 to rotate on the fixed plate 1 through the bevel gear assembly 42, making it easy to control.

[0043] In this embodiment, the positioning mechanism 5 includes a positioning shaft 51 fixedly installed on the top of the rotating shaft 33. A mounting hole 511 is provided inside the positioning shaft 51. A slider 52 is slidably connected to the positioning shaft 51 within the mounting hole 511. Guide posts 53 are horizontally movably inserted through both sides of the positioning shaft 51 outside the mounting hole 511. Positioning plates 54 are fixedly installed at the ends of the two guide posts 53 that are far apart from each other. Hinged rods 55 are hinged to both sides of the slider 52. The free ends of the two hinged rods 55 are respectively connected to the two positioning plates 54. An adjusting member 56 acting on the slider 52 is installed on the positioning shaft 51, which is used to make the slider 52 slide or stop sliding within the mounting hole 511. A flange 6 is sleeved on... Outside the two positioning plates 54, during use, the slider 52 slides within the mounting hole 511 via the adjusting member 56. The two hinge rods 55 rotate around their own hinge points on both sides of the slider 52, and the other ends of the two hinge rods 55 rotate between the two positioning plates 54, causing the two positioning plates 54 to move closer to or further away from the positioning shaft 51 along the two guide posts 53. When positioning the flange 6, the flange 6 is fitted outside the two positioning plates 54, and the slider 52 slides within the mounting hole 511 via the adjusting member 56, causing the two positioning plates 54 to move away from each other along the two guide posts 53. This ensures that both positioning plates 54 abut against the flange 6, thus achieving the positioning of the flange 6.

[0044] In this embodiment, the adjusting member 56 includes a threaded rod 561 that is vertically rotatably mounted on the positioning shaft 51. The bottom of the threaded rod 561 extends into the mounting hole 511 and is threadedly connected to the slider 52. In use, applying a rotational force to the threaded rod 561 will cause the slider 52 to slide within the mounting hole 511, making the operation simple.

[0045] Example 3

[0046] like Figures 1-4 As shown, based on the above embodiments, this embodiment further provides the following:

[0047] In the embodiment, the end of the connecting plate 32 is fixedly provided with a support seat 7 sleeved outside the two positioning plates 54, the top of the support seat 7 is fixedly provided with a plurality of support columns 71 in a vertical manner, the outer side wall of the support seat 7 extends to the outside of the connecting plate 32, and the top of the support seat 7 is inclined downward along the outer side wall. When the flange plate 6 is sleeved outside the two positioning plates 54, the bottom of the flange plate 6 is in contact with the top of the plurality of support columns 71. By arranging the plurality of support columns 71, when the flange plate 6 is positioned, the flange plate 6 is in contact with the top of the plurality of support columns 71, thereby reducing the contact area between the flange plate 6 and the connecting plate 32 and reducing the friction between the flange plate 6 and the connecting plate 32. By arranging the top of the support seat 7 to be inclined downward along the outer side wall, when the flange plate 6 is drilled, the generated waste falls to the top of the support seat 7, thereby sliding outward along the top of the support seat 7 and falling into the waste groove 21, which is beneficial to collect the waste generated by drilling.

[0048] In the embodiment, the top of the support column 71 is ball-connected with a plurality of balls 72, and the bottom of the flange plate 6 is in contact with the plurality of balls 72. By arranging the plurality of balls 72, the bottom of the flange plate 6 is in contact with the plurality of balls 72. When the rotating shaft 33 is rotated on the connecting plate 32 by the motor 34 to drive the flange plate 6 to rotate, the plurality of balls 72 are respectively rotated on the top of the plurality of support columns 71, which is beneficial to smoothly rotate the flange plate 6.

[0049] In the embodiment, the connecting plate 32 is detachably mounted on the top of the mounting seat 31 by the plurality of bolts 8. By the special design that the connecting plate 32 is detachably mounted on the top of the mounting seat 31 by the plurality of bolts 8, the two connecting plates 32 are conveniently detached, thereby facilitating the disassembly, maintenance and repair of the positioning mechanism 5.

[0050] In the embodiment, the outer side wall of the mounting seat 31 is fixedly provided with a support block 311, the bottom of the support block 311 is abuttable with the top of the drilling machine seat 2, and the top of the support block 311 is abuttable with the connecting plate 32. By the design of the support block 311, the connecting plate 32 is supported, and the connection stability between the connecting plate 32 and the mounting seat 31 is improved.
