Description

Multi-axis drilling machine capable of two-dimensional adjustment of drill bits

The present invention provides a multi-axis drilling machine capable of two-dimensionally adjusting a drill bit, which is related to a turning machine.

Press, the drilling machine is a common processing tool, and the general drilling machine is mostly a single-axis drilling machine, that is, a processing machine that can only complete one hole in one process. However, with the diversification of processing and the processing area Amplification, the efficiency of the single-axis processing machine is no longer sufficient.

Therefore, a multi-axis drilling machine A has appeared on the market as shown in Fig. 1. The multi-axis drilling machine A directly uses a turntable A1 and a plurality of adjusting blocks A2 to adjust a plurality of drill bits A3, and provides multi-axis drilling operation through the structural configuration. However, the multi-axis drilling machine A is still limited in processing due to the limitation of the same axial center configuration, and cannot be applied if multiple drilling operations are to be arranged in a straight line; and the turntable A1 of the multi-axis drilling machine A It has multi-directional degrees of freedom, but lacks positioning design. As a result, each of the drill bits that are positioned and changed by each of the adjustment blocks cannot withstand large torque work, and it is easy to generate offset during the processing process and reduce the production yield;

Accordingly, another multi-axis drilling machine B is proposed as shown in FIG. 2. The multi-axis drilling machine B has a plurality of slides B1 combined with the drill bit, and can simultaneously drill a plurality of holes to improve work efficiency. The sliding block B1 of the multi-axis drilling machine B is slidably disposed on a screw B2, and one of the sliding blocks B1 is fixedly coupled to a passive screw B3. The passive screw B3 is screwed on the screw B2. The screw B2 can be rotated by a knob B4, and the rotation of the knob B4 can drive the passive screw B3 and the sliding block B1 fixedly coupled with the passive screw B3, thereby changing one of the drills to the screw B2. The upper position facilitates the drilling of different pitches, and the stable structural configuration improves the working torque range and can be applied to the linear drilling of porous drilling.

However, since each of the drill bits of the multi-axis drilling machine B is slidably disposed on the screw B2 through the sliding block B1, so that the drill bits are located at the same horizontal position, each of the drill bits is in the multi-axis drilling machine B. When processing, both are in the processing position. Therefore, the number of drill holes processed by the multi-axis drilling machine B will be limited to the work of multiples of the drill bit. In the example of Fig. 2, the multi-axis drilling machine B is set. For the four sets of slides B1, the number of holes drilled by the multi-axis drill B will be limited to a multiple of four drilling operations, thus resulting in more processing constraints and the need for improvement. In view of this, the inventors have devoted themselves to research and intensively conceived, and after many research and development trials, finally invented a multi-axis drilling machine capable of two-dimensional adjustment of the drill bit.
