[0026] Please refer to Figures 1 - 7 As shown, a drilling positioning device for machining includes a positioning box 1. The positioning box 1 itself has the same function as a traditional measuring tool. One end of the positioning box 1 is the head end 2, and the other end is the tail end 3. A positioning hole 4 penetrating the head end 2 is provided on the positioning box 1. The head end 2 is used as a positioning function during drilling positioning. A chip removal component 5 is rotatably installed in the head end 2. The chip removal component 5 is used to cut the drill chips. A discharge port 201 is provided on the side wall of the head end 2, and the fine drill chips are discharged through the discharge port 201. An origin component 6 that needs to be placed on the edge of the workpiece is slidably clamped on the positioning box 1. The origin component 6 serves as a positioning reference in this device. During use, the origin component 6 is placed on the edge of the workpiece, and the drilling position is located by the relative distance between the positioning box 1 and the origin component 6. The positioning hole 4 on the head end 2 is used to place the drill bit.

[0027] The chip removal component 5 includes a top plate 501. The top plate 501 is rotatably installed in the head end 2 through an annular clamping member 502. A cutting plate 503 extending downward is fixed to the bottom of the top plate 501, which is convenient for cutting the drill chips and leaving a discharge space for the drill chips. Teeth are provided on the edge of the top plate 501. An intermediate gear 504 is rotatably installed on the top inside the positioning box 1. The intermediate gear 504 meshes with the teeth on the top plate 501, which is convenient for driving the top plate 501 to rotate. A transmission shaft is provided on the intermediate gear 504. An air intake fan 505 is provided at the tail end 3. The drive motor driving the air intake fan 505 is provided with a main shaft rod rotatably connected to the top inside the tail end 3. The transmission shaft and the main shaft rod are power-connected through a transmission belt 506. In this way, when drawing in air flow, the power of the drive motor can be used to drive the top plate 501. The air intake fan 505 is used to introduce external air flow into the positioning box 1. During operation, the power of the drive motor of the air intake fan 505 is used to further drive the top plate 501 to rotate, so that the cutting plate 503 can cut the drill chips. Finally, the fine drill chips can be blown out together with the air flow from the discharge port 201 on the head end 2.

[0028] The annular clamping member 502 includes an embedding portion 521 and a side blocking portion 522. The embedding portion 521 is embedded in the top of the top plate 501, and the side blocking portion 522 is fixed to the inner side of the embedding portion 521. The bottom of the side blocking portion 522 is close to the upper surface of the top plate 501, so as to prevent fine drill chips from being stuck in the top of the top plate 501.

One end of the moving rod 701 is fixed with a lapping plate 702. The side positioning member is used for auxiliary measurement to increase the accuracy of positioning, so as to facilitate accurately measuring the drilling position. Observation lines are provided on both the moving rod 701 and the positioning box 1. Observation members 8 are fixed on the upper surfaces of both the tail end 3 and the bottom plate 602, which can facilitate workers to observe the distance. During use, the lapping plate 702 needs to be closely attached to the side of the workpiece, and then the feed adjustment is carried out through the positioning box 1 to determine the hole position.

[0031] When using this positioning device, it is directly placed on the surface of the workpiece, making the origin assembly 6 closely attached to the edge of the workpiece. The drilling position is located by the relative distance between the positioning box 1 and the origin assembly 6. The positioning hole 4 on the head end 2 is used to place the drill bit. During drilling, the cutting plate 503 can cut the drill chips, and finally the fine drill chips can be blown out from the discharge port 201 on the head end 2 together with the air flow.
