Abstract

Usage: the field of machine tools. SUMMARY OF THE INVENTION: The rotor 1 and sprocket 2 are rotated, as a result of which the movement of the clamping devices installed by the brackets 5 in the links of the chain 3 begins. The smallest distance from the axis of the chain 3 to the axis of the clamping device is equal to the radius of one of the sprockets, for example a driven sprocket 4, due to which, in the sector a of this sprocket, the clamping device is unsuitable, since the turning radius is zero. In this position, the loading of parts or a technological operation can be carried out. 4 ill.

Description

The invention relates to machine tools, in particular to continuous rotary machines, and provides the expansion of their technological capabilities and increase productivity.

The aim of this invention is to increase the technological capabilities of rotary machines:

Figure 1 shows a rotary machine plan; figure 2 is a section aa in figure 1; in Fig.3 - node I in Fig.1; figure 4 is a section bB in Fig.Z.

The rotor machine consists of a rotor 1, on which a drive sprocket 2 is mounted, connected by a chain 3 to a driven sprocket 4. In the links of the chain 3, cantilever clamping devices are fixed using brackets 5. The clamping device includes a collet 6, mounted in a rotary housing 7 with a diameter dK, clamped by a cone 8 with a spring 9. The parts 10 are extruded by the interaction of the fingers 11 with the copier 12. The pitch diameter da of the driven sprocket 4 is equal to: da 2r, where r is the distance from the axis 13 of chain 3 to axis 14 of jig.

The distance L between the clamping devices is equal to:

,

where a is the angle of detail 10,

l d + A (figure 2). All nodes are mounted in the frame.

The rotary machine operates as follows.

The rotor 1 with an asterisk 2 receives rotation from an electromechanical drive.

the devices move in the area of the rotor 1, where the corresponding operations with the parts 10 take place. Then, on the copier 12, indicated by the letter 1, the processed part 10 is unclenched, because. the finger 11 monitors the copier 12 and the cone 8 releases the collet 6. In sector a of the driven sprocket 4, the part 10 is expanded and stationary, ™, the turning radius is zero and the speed of movement of the part is zero. At this moment, the part 10 changes during continuous rotation of the rotor 1 and, with further movement, the part 10 is clamped by the collet 6. Since the pin 11 slides off the copier 12 and the spring 9 retracts the cone 8. The spread of the collet petals 6. The process is repeated.

The cost-effectiveness of this invention is to increase technological capabilities, thereby increasing the versatility of the device.
