Technical Field

[0001] The utility model relates to the technical field of flute processing, in particular to a positioning drilling device used for flute manufacturing. Background Art

[0002] In the flute production process, the flute tube is first made, and then holes need to be drilled on the flute tube. The traditional method is to drill holes manually using a drilling tool. This method is inefficient. Second, after manual drilling, the multiple holes drilled may be offset and not in a straight line. The existing Chinese utility model patent with the announcement number "CN218748282U" and the patent name "A positioning drilling device for flute manufacturing" discloses a flute drilling device, which can drill holes in the flute tube by moving the drill bit. However, the device has the following problems: first, the moving drill bit is relatively unsafe, and second, the flute tube is fixed by a spring and a special-shaped block, which is very unstable. Therefore, a new drilling device is needed to solve this problem. Utility Model Content

[0022] Example

[0023] A positioning drilling device for flute manufacturing includes a drilling machine 1, the drilling machine 1 includes a liftable drill bit 11 and a workbench located below the drill bit 11, a mounting plate 2 is provided on the workbench, the mounting plate 2 can move back and forth laterally relative to the drill bit 11, and a fixture 3 for clamping the flute is provided on the mounting plate 2.

[0024] Furthermore, the clamp 3 includes a pull rope 31 arranged on the mounting plate 2, and a plurality of pull ropes 31 are provided. One end of the plurality of pull ropes 31 is fixed side by side on the mounting plate 2 along the moving direction of the mounting plate 2. One side of the mounting plate 2 is provided with through holes in parallel, and one end of the pull rope 31 passes through the through holes. The end of the pull rope 31 passing through the through holes is connected to a pulling mechanism.

[0025] Furthermore, the pulling mechanism includes an electric pull rod 32 fixedly connected to the mounting plate 2 , and a working end of the electric pull rod 32 can pull the pull rope 31 .

[0026] Furthermore, one end of the pull rope 31 passing through the through hole is connected to a connecting plate 33 , and a working end of the electric pull rod 32 is connected to the connecting plate 33 .

[0027] Furthermore, the working end of the electric pull rod 32 is horizontally arranged and perpendicular to the moving direction of the mounting plate 2 .

[0028] Furthermore, a pulley 34 is provided at the side of each through hole at the bottom of the mounting plate 2 , and the pull rope 31 passes through the through hole and then bypasses the pulley 34 to be connected to the connecting plate 33 .

[0029] Furthermore, the pull rope 31 is made of rubber.

[0030] Furthermore, a spring 35 is vertically arranged in the through hole, one end of the spring 35 is fixedly connected to the mounting plate 2, and the other end is fixedly connected to the pull rope 31. When the spring 35 is in a natural state, the space surrounded by the pull rope 31 above the mounting plate 2 is larger than the diameter of the flute to be processed.

[0031] Furthermore, a lead screw 41 is rotatably provided on the workbench, a guide rod 42 is fixedly provided on one side of the workbench parallel to the lead screw 41 , and the bottom of the mounting plate 2 is fixedly connected to the lead screw 41 nut of the lead screw 41 and is slidably connected to the guide rod 42 .

[0032] Furthermore, a driving motor 43 is connected to one side of the lead screw 41 .

[0033] The working principle of this embodiment is as follows:

[0034] During operation, the flute tube is placed on the mounting plate 2 and passed through the pull rope 31. At this time, the pull rope 31 is in a relaxed state. After it is placed, the pull rope 31 is tightened by the electric pull rod 32. After the pull rope 31 is tightened, the flute tube is clamped. Moreover, the pull rope 31 is made of rubber and has a large friction with the flute tube. The flute tube will not move or rotate under the action of the pull rope 31. After the flute tube is clamped, the drill bit 11 moves downward to drill a hole in the flute tube. After a hole is completed, the drill bit 11 rises, and then the motor 43 starts to drive the lead screw 41 to rotate.
