Referring to Figure 6, the conventional multi-axis drilling and milling power head still has many shortcomings to be improved. Among them, the conventional multi-axis drilling and milling power head has two sets of collets 41 with a radial angle of 90 degrees, and two Each of the chucks 41 requires two power shafts for transmitting power, and each set can preset each of the chucks 41 to be linearly arranged; therefore, the internal transmission uses a number of idlers 40 to transmit power, so that the chucks 41 is the same steering operation, but since the power is transmitted through each of the idler wheels 40, the gear gap between the internal parts is large, and the amount of noise generated during operation is high; in addition, the idler gears 40 are insufficiently torqued due to indirect transmission, and The speed of each of the chucks 41 is also limited; when the power is transmitted through a large number of parts, the internal temperature is easily increased after a long time of operation, thereby affecting lubrication and other problems; in addition to the internal overall maintenance and repair It is not only time-consuming but also a significant increase in costs, which has long plagued relevant personnel.

Therefore, in view of the problems existing in the above-mentioned conventional multi-axis drilling and milling power head structure, how to develop an innovative structure with more ideal and practicality, the relevant industry players need to work hard to develop the breakthrough goal and direction.

In view of this, the new creator has been engaged in the manufacturing development and design experience of related products for many years. After detailed design and careful evaluation, the new creator has finally achieved a practical new creation.

In view of the problems existing in the above-mentioned conventional drilling and milling power head, the novel creation system provides a direct transmission multi-axis drilling and milling power head, which adopts a power spindle to set the number of active bevel gears to directly transmit power to the number of passive umbrellas. The gears achieve the effect of avoiding the influence of the clearance of the machine parts, so that the overall machining accuracy is improved, and the high torque and high speed are excellent because of the direct transmission of power, and the overall structure is small in size and space-saving.

In order to achieve the above purpose, the present invention provides a direct transmission multi-axis drilling and milling power head, comprising: a body, the body is a quadrangular cylinder and the power spindle is arranged in the axial direction, and the preset position on the power spindle Wear each of the active bevel gears.

The output shafts are radially mounted on the body, and each of the output shafts respectively wears the passive bevel gears, and the passive bevel gears vertically mesh with the active bevel gears.

Each of the output shafts is respectively connected to a tool chuck, and each of the output shafts forms an angle in a radial direction of the body, the angle being an angle of 90 degrees.

Wherein, each of the tool chucks is axially arranged on both sides of the outer portion of the body.

The body may also be a polygonal cylinder.

Wherein, each of the active bevel gears and each of the passive bevel gears may be a spiral bevel gear.

The structure used above is directly driven by gears during operation, so the cutting force is strong, the speed is not lost, the force is not lost, and the life of the machine is increased; and the noise is greatly reduced during operation, and the machining accuracy is improved, and the working efficiency is improved; the overall structure is small, No space is required for installation and use to increase the range of applications.

With regard to the techniques, means and functions of the present invention, a preferred embodiment will be described in detail with reference to the drawings and drawings, and the reviewer will be able to have a more detailed understanding of the novel and familiarize himself with the The skilled artisan can implement the following, and the following is only to explain the preferred embodiment and not to limit the scope of the novel, so any form of change based on the creative spirit of the present invention. Or modifications are within the scope of this new type of protection.
