Description

Detailed Description of the Invention (Industrial Application Field) The present invention provides a transfer device that transfers a rotating long material in the axial direction from a long transfer guide path and supplies it to a processing machine. This invention relates to a steady rest device that is placed near the rear of a machine to prevent swinging of a rotating long material.

(Prior art) Conventionally, a long material M, which is a workpiece, is passed through an automatic processing machine 1 from the rear, gripped by a chuck 2 provided at the front, and sequentially moved forward into a predetermined position. Devices for transferring and supplying materials in a pinch are known.

As shown in FIG. 26, in this transfer device, a long fixed frame 4 having a transfer end 3 at the tip is installed horizontally as a fixed side, and a long fixed frame 4 is installed horizontally on the fixed side. While the long materials M waiting in parallel are configured to be introduced one by one by transfer, the introduced long materials M are placed in the chuck-equipped automatic processing machine 1 installed in the same row in front of the fixed frame 4. It is configured to be carried in and held by the chuck 2. On the transfer mechanism side, rotatable first and second wheels 6.7 are provided at the front transfer end 3 and rear end 5 of the fixed frame 4, and these wheels 6.7 are rotatable.
An endless chain 8 with a certain amount of slack is hung between 7 and 7, and a long material held by the chuck 2 of the automatic processing machine 1 is placed around the upper part of the chain 8. A pushing part 9 is provided that urges the rear end of the paper and pushes it in the transfer direction (see Japanese Patent Publication No. 56-20128).

(Problems to be Solved by the Invention) In the conventional apparatus described above, when the long material M is rotated at high speed by the automatic processing machine 1, the long material M swings vertically and horizontally with the rotation. Vibration is transmitted to the front end, that is, the machining part, which not only reduces machining accuracy, but also damages the machining tool and may lead to machining difficulties.

(Means for Solving the Problems) In view of the above-mentioned circumstances, the present invention aims to provide a steady rest device for a rotating body that can prevent runout by mechanical means, and its features are as follows. , in which a rotating long material M is transferred forward in the axial direction from inside the long guide trough 40 and supplied to the processing machine 11, in which the inside is placed between the guide trough 40 and the processing machine 11. A housing 171 through which M passes is rotatably provided around a support shaft 172 perpendicular to the transport direction of the long material M, and a pair of housings 171 are arranged in the housing 171 in the transport direction of the long material M with the support shaft 172 in between. In addition, nonmetallic contact rings 167 and 168 whose axes are located on the transport path of the long material M are rotatably provided for the axes, and each contact ring 167 is rotated around the support shaft 172 by rotating the housing 171 around the support shaft 172. .168 is provided with a drive device 175 that brings the inner circumferential surface of the long material M into contact with the elongated material M from opposite sides.

(Function) When the long material M, which is a rotating body, is inserted into the center of the contact rings 167 and 168 and is gripped by the chuck 12 of the automatic processing machine 11, the support shaft 172 is rotated and the housing 171, that is, the central axes of the contact rings 167 and 168, are tilted with respect to the central axis of the long material M, so that one contact ring 167 is placed on one side of the long material M, and the other contact ring 167 is placed on the opposite side of the long material M. When the long material M is rotated after the contact rings 168 of the contact rings 168 are brought into contact with each other, the contact rings 167 and 168 are also rotated by the long material M. The long material M is supported in opposing directions, and even if it tries to swing in a direction perpendicular to this, its movement is regulated by the arcuate inner surfaces of the contact rings 167 and 168, and swing is completely prevented. Axial transport also occurs smoothly.

rotates, and the long material M is supported by hydraulic oil. As machining progresses, hydraulic oil flows out from the front end of the guide trough 40, but since hydraulic oil is supplied from the injection opening 50 to prevent this, the long material M is reliably supported by the hydraulic oil. It is moved forward intermittently by the push chain 18 at a predetermined pitch. Hydraulic oil leaking rearward from between the destination shaft 93 and the guide gutter 40 flows down from the hydraulic oil return hole 47 into the recovery gutter 22 and is recovered. The finger chuck 86 is
When advancing to the hydraulic oil injection opening 50, the supply of hydraulic oil is stopped, and then the long material M is advanced without being supported by the hydraulic oil, and the finger chuck 86
When the tool moves forward to a predetermined position within the automatic processing tall, processing is completed and the chuck 12 is released. Note that until this state (see FIG. 2) is reached, the sliding guide vane @123 of the destination shaft 93 comes into contact with the front end plate 30 and stops, and at the same time, the sliding guide vane 123 is stopped by the locking ball 127. The feed arrow 17 moves forward. Then, when the long material M is released from the chuck 12, the chain drive wheel 38 is reversely rotated, and the chain 718 is rewound and fed into the chain storage box 20. At this time,
The destination shaft 93 is still in the locked state, but the locking balls 102 and 103 of the mounting body 88 are in the annular locking grooves 124 and 125.
When the pawl ring retaining collar 106 contacts the destination shaft 93, the destination shaft 93 retreats together with the mounting body 88 of the feed arrow 17. When the finger chuck 86 passes slightly past the removable mold 155, the removable device 154 is activated and the removable mold 155 clamps the machining residual material, so that the machining residual material is transferred to the finger chuck 86.
When the workpiece is separated from the workpiece and the clamp by the detachable claw 155 is released, the leftover material falls and is stored in the leftover workpiece input box 152. In this way, when the feed arrow 17 returns to the predetermined retreat position, the chain drive wheel 38 is stopped and the opening/closing lid 4 is stopped.
5 is opened, the next elongated material M is introduced into the guide trough 40, and the operations are repeated in the aforementioned order.

In this embodiment, the chino 18 for pushing the long material has a fourth
As shown in the figure, a link 18A with a protruding sliding guide piece 52 was used, but as shown in Figures 24 and 25, both ends of the pin 184 are extended outward to allow the sliding guide piece to move. year,
The guide rail 41 provided in the guide gutter 40 of the transfer guide path 16 can be provided such that the center of the chino guide recess 51 is located within a plane containing the central axis of the guide gutter 40. Further, the guide gutter 40 can be a single metal gutter without having a double pipe structure.

(Effects of the Invention) As described above, the steady rest device according to the present invention includes two contact rings 167 and 168 made of non-metallic material rotatably fitted to the housing 171 via the rotary support 169, By inserting the elongated material M into the center of the contact rings 167 and 168 and tilting the housing 171, the elongated material M is brought into contact with and supported by the contact rings 167 and 168, and the rotating elongated material M supports the contact ring. 167.16
8 can be rotated together, the swing of the long material M is completely prevented, and the long material M can be rotated and transferred smoothly by simply rotating the support shaft 172. The contact rings 167 and 168 can be attached to and separated from the long material M, and even if the diameter of the long material M changes, the contact rings 167 and 168 can be replaced or a separate device must be prepared according to the diameter of the long material. This method can be applied to long materials having a wide range of diameters without such trouble, and it is possible to improve the machining accuracy and quality of the long materials M.
