Detailed ways

The utility model will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. However, it should be noted that the description of the following embodiments is schematic and does not constitute a specific limitation to the utility model.

With reference to Fig. 1 to Fig. 6, a kind of two-way drilling machine of the present utility model comprises: workbench 1, is provided with a frock base 2 on the workbench 1, and the workbench 1 is slidably provided with two two positions respectively located at the frock base 2 The drilling head 3 on the side, the two drilling heads 3 are relatively arranged on the same straight line, the tooling base 2 is provided with a tooling main body 4 for placing the workpiece 10, and the tooling main body 4 is penetrated with two drills. The first through-hole groove 41 corresponding to the drilling portion 11 on both sides of the hole head 3 and the workpiece 10 has a diameter slightly larger than the diameter of the drill bit. The upper pressing block 5 and the driver 6 for driving the pressing block 5 to reciprocate up and down, the driver 6 is a cylinder connected to the pressing block 5 or a screw nut structure driven by a motor. The double-hole drilling machine with the above structure uses the relative movement of the two drilling heads 3 arranged concentrically to simultaneously drill holes on both sides of the product, which greatly improves the work efficiency and effectively ensures the simultaneous drilling of the two sides. Axis, the first through-hole groove 41 coaxial with the drilling head 3 and the drilling part 11 of the workpiece 10 runs through the main body 4 of the tooling, preventing the drill bit from piercing the main body 4 of the tooling during the drilling process, and has a certain guiding effect , to prevent drilling position offset, improve accuracy.

Both sides of the tool body 4 respectively define a positioning notch 42 for inserting the drilled portion 11 of the workpiece 10 , and the positioning notch 42 communicates with the first through-hole groove 41 .

The front end of the tool body 4 is provided with a positioning block 43, and a positioning socket 44 extending downward is provided on the positioning block 43. The side wall of the positioning block 43 is penetrated with a second through-hole groove 431 communicating with the positioning socket 44. A positioning pin is movably disposed on the through hole slot 431 . The positioning socket 44 corresponds to the shape of the positioning portion 12 of the workpiece 10. The positioning portion 12 of the workpiece 10 is provided with a through-hole groove 13. When the workpiece 10 is placed on the tool body 4, the positioning portion 12 of the workpiece 10 is inserted into the positioning socket. 44, and a positioning pin passes through the second through hole groove 431 and the through hole groove 13 of the positioning part 12 of the workpiece 10, thereby positioning the workpiece 10 and preventing the workpiece 10 from moving during the drilling process.
