Description

[Detailed explanation of the invention] (Purpose of the invention) This invention rotates a slide shaft with a hand attached to the tip to connect the lathe and machine base when performing work such as exchanging and setting the cutting tool. This invention relates to an automatic workpiece feeder for a lathe that has a wide space between the parts, thereby making it easier to perform the above-mentioned operations such as changing and setting the cutting tool.

(Prior art) A lateral movement table is mounted on a machine base installed on the side of the chuck of a lathe so that it can move freely in the axial direction of the main shaft of the lathe, and a slide shaft with a hand attached to the tip is attached to the lateral movement table to move the slide shaft toward the axis. In an automatic lathe workpiece feeder that is installed so that it can move forward and backward in a direction perpendicular to the center, even when the slide shaft is moved backward, the space between the tip of the slide shaft and the lathe is narrow, making it difficult to replace the cutting tool, When performing work such as setting, the slide shaft gets in the way, and you have to perform the above tasks in an unnatural posture, resulting in poor work efficiency. There were cases where the body was injured by the hand.

(Structure of the invention) The present invention was made in view of the above-mentioned problems, and its gist is that a rotary plate is attached to the top surface of a machine stand installed on the side of the chuck of a lathe, and is fixed and rotatable about a vertical axis. A horizontal moving table is mounted on the rotary plate so as to be linearly movable, and a slide shaft with a hand attached to the tip of the horizontal moving table can be moved back and forth in a direction perpendicular to the direction of movement of the horizontal moving table. It was installed on the

An embodiment of the present invention will be described below with reference to the attached drawings. In Figs. 1 and 2, a machine stand 1 is installed on the side of a chuck C of a lathe such as an NC lathe or an automatic lathe. A fixing plate 3 is formed in the center of the turret with a bearing 2 protruding from the plate surface with its axis perpendicular to the plate surface.
The fixing plate 3 is fitted into a fitting hole 5 formed approximately in the center of the upper plate 4 of the machine, and the fixing plate 3 is fixed to the upper plate 4 of the machine base 1 with a pin 6.

In addition, a cylindrical fitting body 7 is protruded from the center of the dowel with its axis perpendicular to the plate surface, and a circular arc groove 8 having a central angle of about 90' with respect to the axis of this fitting body 7 is provided. The cut rotating plate 9 is shaped, and the fitting body 7 of the rotating plate 9 is attached to the bearing 2 of the fixed plate 3.
were fitted, and the rotary plate 9 was placed on the fixed plate 3, a male screw 10a was screwed into the tip, a flange 10b was formed in the center, and a handle 10c was fixed to the upper end. Insert the fastener 10 into the circular arc groove 8 of the rotating plate 9, and tighten the male screw 1 at the tip.
0a is screwed into a female terminal (not shown) screwed into a predetermined position of the fixed plate 3 and tightened, the rotating plate 9 is fixed to the fixed plate 3.
Fix it in place.

In addition, as shown by solid lines in FIGS. 1 and 2, the rotating plate 9
A pair of supports 11 are fixedly installed at a required interval, and both ends of two mutually parallel guide bars 12 are supported by the pair of supports 11, and a metal plate is fixedly installed at the bottom of both ends of the lateral moving table 13. 14 is slidably fitted into the guide bar 12.

A slide metal 15 is fixed to the lateral movement table 13 , and a slide shaft 16 and a guide rod 17 are slidably inserted into the slide metal 15 at right angles to the moving direction of the lateral movement table 13 . Bracket 1
An air cylinder 19 for advancing and retracting is attached through The ends are connected by a rear end connecting plate 22, and a hand H for gripping the workpiece W is attached to the tip connecting plate 21 via a support plate 23.

In the figure, A is a workpiece supply chute, which is fixed to the end of the rotating plate 9, and B is a workpiece supply chute for supplying the workpiece W from the workpiece supply chute A to the hand H for one piece. The mechanism is fixed to the end of the rotating plate 9 via an arm 24.

Further, D is a chute for carrying out products, and is fixed to the end of the rotating plate 9 via an arm 25.

(effect of invention) Next, the operation of the present invention will be explained.

In the normal case where the workpiece W is automatically supplied to the lathe, the axial center of the slide shaft 16 and the axial center X-X of the main shaft of the lathe are at a right angle, as shown by the solid line in Fig. 2. , the rotating plate 9 is fixed to the machine base 1 with a fastener 10.

In addition, when performing various operations such as exchanging and setting the cutting tool, tighten the fastener 10 and release the fixation between the rotating plate 10 and the machine base 1, as shown by the two-dot chain line in Fig. 2. By rotating the rotating plate 10 approximately 90 degrees in the direction of arrow P about the vertical axis, the slide shaft 16, work supply chute A1, work supply mechanism B, and product unloading chute D are rotated approximately 90 degrees. , the space S between the machine stand 1 and the lathe is widened, and various operations such as exchanging and setting the above-mentioned cutting tools are performed.

(Effects of the invention) This invention consists of attaching a rotating plate to the upper surface of the machine base installed on the side of the chuck of the lathe, so that it can rotate freely around a vertical axis and also fixedly. The slide shaft with a hand attached to the tip is attached to this horizontally moving table so that it can move freely in a straight line, and it can move forward and backward in a direction perpendicular to the direction of movement of the horizontally moving table, so it is easy to change the tool, set it, etc. When carrying out work, unfasten the rotating plate from the machine base, rotate the rotating plate at the required angle around the vertical axis, and rotate the slide shaft to easily connect the lathe to the machine base. The space between the tools can be widened, and the above-mentioned operations such as exchanging and setting the cutting tools can be performed quickly and safely.
