Abstract

PURPOSE:To enable various types of integrating and thread fastening works and automated assembly of various kinds of products in an automatic assembling machine by providing a thread fastening axis in a chuck exchange device so as to automatically exchange a chuck with a single chuck exchange device. CONSTITUTION:A chuck exchange device consists of a spindle a10, a spindle b2, a chuck clamp axis 11, an air supply axis 12 and a thread fastening axis 13, and a thread fastening chuck 14 is clamped to the tip end of the spindle a10 by a rigid ball 15 of the axis 11. A clamping force of the chuck 14 is given by a spring 16. Unclamping of the chuck 14 is done by driving the chuck clamp axis 11 having seals 17 and 18 through compressed air. The air supply axis 12 supplies air to three systems of up and down of the chuck exchange device, chuck unclamping, and a vacuum for chuck. The thread fastening axis 13 is directly connected to a thread fastening motor 25, rotates the axis of the chuck 14 and carries out thread fastening.

The clamping force of the chuck is provided by a spring 16. To unclamp the chuck, use compressed air to seal 1.
The air supply shaft 12 is connected to the spindle b2 by rotating the chuck clamp shaft 11 having the numbers 7 to 18.
and a bearing 19.20 in the chuck clamp shaft 11.
and seals 18, 21, and 22, and supplies air to three systems: upper and lower chuck exchanger, chuck unclamp, and chuck vacuum. Each air passes through a path within the air supply shaft 12, and the air enters the cylinder 3.
, chuck clamp shaft 11. It is supplied to the screw chuck 14. Since the air supply shaft 12 is fixed to the frame cover 24 by a rotation stopper 23, it will not rotate even if the chuck exchange device rotates, so that twisting of the air piping of the three systems can be prevented. . Furthermore, by arranging the seals 21 and 22 on the upper part of the chuck clamp shaft 11, the seal diameter can be made smaller and the friction torque is reduced, making it possible to rotate the chuck changing device with the small output servo motor 4. It becomes possible.
