Description

Automatic turning and corner cutting machine

The invention relates to an automatic turning corner cutting machine with the functions of corner cutting and turning, in particular, it refers to a machine composed of a main shaft, a driven shaft with axial sliding teeth and other components, which can increase the processing range. design, and can additionally have the effect of making power transmission smoother.

As the manufacturing level of modern industry is improving day by day, automatic corner cutting machines and automatic turning machines that can make the corners of processing components into polygonal shapes (such as: nuts, studs, etc.) are indispensable in current automated machinery There are several kinds of machines and tools, and the automatic angle cutting machines that are generally seen at present are very diverse. However, whether the processing range of automatic machinery is sufficient and whether the transmission condition is smooth has become the most important feature of the user; therefore, how to develop a processing range is more important. Automated machines with sufficient resources and smoother transmission conditions have long been the problems that developers and manufacturers most want to overcome, and the problems presented in the above content are also the motivation of the inventors to develop the present invention.

The traditional automatic angle cutting machine, please refer to Fig. 1, this kind of commonly used automatic angle cutting machine is equipped with a power mechanism in the bed frame 10, and the power will make the main shaft 11 and chuck 12 located on the side of the bed frame 10 Rotate together, and the main shaft 11 will transmit the power to the transmission shaft 13 on the same side with the preset transmission parts, and the other side of the bed frame 10 is equipped with a cutter seat 14, and the cutter seat 14 corresponds to the 12 sets of chucks A cutter chuck 15 is provided, and a sliding seat 16 is set between the cutter seat 14 and the bed frame 10. The drive shaft 13 transmits power to the cutter seat 14 by means of a universal joint 17 and an extension rod 18. Cutter chuck 15; please refer to shown in Fig. 2, so when the power of bed frame 10 makes chuck 12 and cutter chuck 15 rotate relative to a certain ratio, the cutting knife 19 on this cutter chuck 15 just The workpiece on the chuck 12 can be angled; this kind of automatic angle cutting machine commonly used has been sold and used for a long time on the market, but this kind of design still has shortcomings in practicability and operation, so that its effect is not obvious. The reason is that:

First, if the cutter chuck 15 needs to cooperate with a workpiece with a larger outer diameter, then the cutter chuck 15 needs to be radially displaced by the sliding seat 16 corresponding to the chuck 12, but the transmission shaft 13 uses two universal joints 17 Transmission of power with an extension rod 18, so the two universal joints 17 will coordinate with the radial displacement of the cutter chuck 15 to drive obliquely, so that the axial rotation of the extension rod 18 will be affected by the deflection angle and not smooth, And when the oblique angle of the two universal joints 17 is too large, it is more likely to cause deformation and jamming of the transmission structure;

Second, because the cutter chuck 15 needs to cooperate with the displacement of the workpiece, the cutter chuck 15 needs to be displaced laterally or radially with the slide seat 16 corresponding to the chuck 12, but the angle at which the two universal joints 17 can be transmitted obliquely limited, and the extension length of the extension rod 18 is also limited, so the traditional automatic corner cutting machine processing range is not sufficient;

Third, since the power system, processing method and structural cooperation method of the automatic corner cutting machine and the turning machine are very similar, and the general workpiece often requires two kinds of processing, the corner cutting and the turning, so the processors of the traditional automatic corner cutting machine often use it in order to carry out The turning work affects the overall work progress and efficiency, and the manufacturer needs to purchase two types of machines with very similar motion patterns, which obviously wastes cost and space.

For the shortcomings of the above-mentioned traditional automatic angle cutting machine, the current improvement trend is to increase the oblique angle of the two universal joints 17 as a requirement. With creative and functional improvements, it is hoped that the practicability of the automatic corner cutting machine will be greatly improved; after many times of research and development and trial production, a machine with corner cutting and turning functions, smoother power transmission and increased processing range has finally been invented.
