Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a dedicated processing machine in which a spring insertion device is incorporated at the tip of a saddle tip into a punch tip processing machine for launching pachinko balls.
[0002]
[Prior art]
Conventionally, after processing the scissors with a lathe, the processed scissors are moved to the work place where the springs are press-fitted and press-fitted.
FIG. 8 is a first example of a conventional method. A hole 12 for standing the spring 11 is formed in the block 10, the spring 11 is inserted into the tapered tip pin 14 of the flange 13, and the end surface of the tapered tip pin 14 is stroked with a hammer or the like, or pressed with pressure. It was press-fitted.
9 and 10 show a second example of the conventional method. The tightly wound portion of the spring 11 that was press-fitted into the tapered tip pin 14 of the heel 13 was fixed with a pliers 16 and the end surface of the heel tip was pushed in with a hammering pressure.
[0003]
[Problems to be solved by the invention]
In the above prior art, differences in the spring length after press-fitting, differences in the winding end position of the contact surface of the pachinko ball of the spring, bending of the spring, differences in press-fitting and torsional distortion, etc. occur. In order to affect the variation of the ball jump, a large variation of the ball jump was generated by the kite.
In order to work in a different place after processing the paddle, there was a time loss for moving, and a storage place and work place were also required.
Although the tip end spring insertion device is known, there is a problem that the control system of the device is complicated and expensive, and a time loss is large because the setting is performed again.
[0004]
[Means for Solving the Problems]
The present invention aims to solve the above-mentioned problems , and a sliding tool post that slides back and forth and back and forth of an NC lathe slides a pachinko ball launching tip spring press-fitting part cutting tool and spring holder to the left and right. Installed side by side in the direction, attached a scissors set base to the chuck body, which is the main spindle of the NC lathe, fixed the scissors with the chuck claw, and after cutting the scissors with the cutting tool, slidably moved the tool post to the center of the spring holder And the machined hook spring insertion part can be matched, and the hook pin is inserted linearly to the point where the outer diameter of the hook pin matches the spring inner diameter, and then fixed to the rotating main shaft with chuck claws. the relative movement of the spring is set earlier pin and the spring holder so screwed by the rotation of the quantity Dzuzu mallet destination pins of wire diameter pitch of the spring, always screwing in the amount of rotation of the provisions, it is reversely rotated screwing the end after the main shaft The tip pin and the bar It has a function of extracting the spring holder from the spring by reverse rotation of the net holder in the reverse rotation.

DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the present invention will be described in detail based on the illustrated examples. 1 to 7 show an embodiment of the present invention.
This is an embodiment in which the spring holder 7 is attached to the tool post of the NC lathe for cutting the tip. In the NC lathe, the rotation angle of the spindle, the rotation speed, and the positional relationship of the machining blade are set and controlled. A collar set base 3 is attached to the chuck body 2 on the main shaft, and the collar 4 is fixed with chuck claws. Reference numeral 5 denotes a sliding turret, which controls the mounting position of the cutting tool 6 and the spring holder 7 so that the center of the spring holder 7 and the center of the tip pin coincide with each other to feed the turret 5 and rotate the spindle. The spring 8 is inserted by relatively controlling the above.
Set the heel 4 on the heel setting table 3, set the spring to the mark 9 on the spring holder 7 so that the spring winding end position is aligned, and start. The hook 4 is chucked, the spindle starts rotating, and the tip pin is cut in the programmed machining process to finish the machining.
[0006]
Next, the control of the insertion process of the spring 8 is started, the spring holder 7 is moved to a position coincident with the center of the tip pin, the chuck body (main shaft) 2 on which the hook 4 is set is not rotated, and the spring holder 7 is set. It moves forward to the linear movement position (point where the inner diameter of the spring and the outer diameter of the tip pin substantially coincide). From this point, while rotating the main shaft, the spring holder 7 advances by an amount corresponding to the element wire diameter pitch of the spring, the spring 8 is screwed to the set end position, the set rotation amount main shaft is rotated, and the screwing process is completed. Next, by retracting the spring holder 7 while rotating the main shaft in the reverse direction, the spring 8 is removed from the spring holder 7 and the spring holder 7 returns to the standby position to complete the operation.
In order to adjust the difference due to the variation between lots of 槌 4, the hole guide pin that uses the 槌 rotation shaft hole of the 槌 set stand 3 as a guide, the stopper member of the 胴 barrel part, the 槌 head, the fixed chuck claw It has a fine adjustment function to match the center of the tip pin (not shown).
In the embodiment, the main shaft is rotated and the spring holder 7 is moved. However, the spring holder 7 may be incorporated in a driving unit for controlling the rotation of the spring holder 7 and incorporated in the tool post. Further, the unit for setting the spring holder 7 may be attached by providing a center pushing cup or a dedicated mounting base. Since the movement and rotation are relative to each other between the spring and the tip pin, any combination is possible.

【The invention's effect】
The present invention provides a sliding tool post that slides back and forth on the left and right sides of an NC lathe and attaches a cutting tool and a spring holder at the tip of the pachinko ball launcher side by side in the left-right sliding direction. A hook set base is attached to a chuck body, the hook is fixed with a chuck claw, and after cutting the tip with the cutting tool, the tool post is slid to move the center of the spring holder and the machined spring insertion part of the hook Insert it linearly to the point where the outer diameter of the tip pin and the spring inner diameter match, and then fix the tip pin fixed to the rotating spindle with a chuck claw and the spring set in the spring holder . The relative movement of the tip pin and the spring holder is determined by the amount of the wire diameter pitch of the spring , screwed by the rotation of the tip pin , always screwed in the specified amount of rotation, and after the screwing is finished, the main shaft is rotated backward. To reverse rotation backward Since the spring holder has a function to remove the spring holder from the spring, there is no time loss due to the movement of parts, no work storage space and no spring press-in space are required, and work can be performed in a reasonable work environment. It was.
In addition, since the NC lathe control program can be ideally controlled even if it is not an expensive saddle tip spring press-fitting device, the spring length after press-fitting and the end of winding of the contact surface of the pachinko ball of the spring are not required. Position, press-fitting and torsional distortion became uniform, and the springs were not bent and collapsed, so that it was possible to stably supply the wrinkles free of ball jumping.
