Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a valve drilling device for drilling a valve hole in a rim wall of a vehicle disc wheel.

[Conventional technology]

Conventional valve drilling equipment supports a punch in the upper jaw of a U-shaped frame in which the upper and lower jaws extend horizontally so that it can move up and down, inserts the rim of a disk wheel (workpiece) between the punch and the lower jaw, and presses the cylinder into the cylinder. The punch was driven downward to punch a valve hole in the rim wall.

[Problem that the invention attempts to solve]

However, the position of the valve hole in the rim of the disc wheel is inclined with respect to the axis of the disc wheel, so in order to apply the punch perpendicularly to the rim wall, it is necessary to place the disc wheel on the press in accordance with the inclination of the rim wall. It must be carried in at an angle,
This made the work of drilling the valve holes difficult. For this reason, one person is attached to each press, picks up the disc wheel flowing down the line by hand, inserts the disc wheel diagonally into the press, and returns it to the line after drilling. In terms of speed, two presses had to be installed on the line, so two people were required to perform the process, and there was a desire to save labor and improve efficiency.

The present invention makes it possible to insert the disc wheel into the press with the shaft center vertical by tilting the valve punch side during valve drilling work of the disc wheel.
The purpose of this is to make valve hole drilling work easier and save labor.

[Means for solving problems]

To achieve this object, the disk wheel valve drilling device according to the present invention includes a frame that has a slide base that is horizontally slidable and supports the slide base so that its position can be adjusted in the horizontal direction;
A U-shaped member having a guide tiltably supported on a slide base of the frame, an upper jaw and a lower jaw slidably supported by the guide, and a U-shaped member having a vertical position relative to the guide by moving the U-shaped member up and down relative to the guide. a punch mount attached to the U-shaped member so as to be slidable between the lower jaw and the maxilla; a cylinder attached to the upper jaw to slide the punch mount in the direction of inclination of the U-shaped member; It consists of a punch set on a mounting base, and a device for inserting the rim wall of the disc wheel between the punch and the mandible to punch a valve hole in the rim wall.

[Effect]

In the above device, the U-shaped member having the upper and lower jaws is set to be inclined relative to the frame, and the axis of the punch is inclined by the inclination of the rim wall. In this state, lay the disc wheel sideways so that its axis is in the vertical direction, and insert it horizontally between the punch and the mandible, so that the tilted driven punch hits the valve hole drilling position on the rim wall at right angles. be able to. This eliminates the need to insert the disc wheel into the press at an angle; therefore, it is sufficient to insert the disc wheel right sideways so that the rim wall is between the punch and the lower jaw, and the disc wheel is placed next to the valve drilling device. All you have to do is slide it onto a horizontal table and insert it into the press, which greatly simplifies the valve hole drilling process.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, preferred embodiments of a disc wheel valve drilling device according to the present invention will be described with reference to the drawings.

1 to 3 show an embodiment of the invention. In the figure, a frame 1 has a screw means 3 with a handle 2 as a horizontal adjustment means, and a slide table 1a at the upper part of the frame 1 can be horizontally moved relative to a lower part 1b, and a workpiece 4. When the size of the disc wheel changes due to a change in the type of disc wheel flowing through the line, the horizontal position of the line perforation can be adjusted. This is the stopper (not shown) when workpiece 4 is pushed into the drilling position.
However, since its horizontal position is fixed, when the size of the workpiece changes, the punch position must be changed horizontally accordingly.

A guide 21 is provided on the slide base 1a of the frame 1.
is supported by a fulcrum 8 so that its inclination angle can be adjusted, and a U-shaped member 7 having an upper jaw 5 and a lower jaw 6 is attached to the guide 21 so as to be slidable in the direction of inclination of the guide 21. The angle of inclination of the guide 21 and the U-shaped member 7 with respect to the frame 1 can be adjusted by connecting a screw means 10 having a handle 9 to the guide 21 at a connection point 22 and turning the handle 9. The U-shaped member 7 is the disk wheel 4
The valve hole axis at the valve hole drilling position of the rim 4a is tilted by an angle θ (see Fig. 1) with respect to the axis of the disc wheel 4, and at this position, the lever 12 is used to tighten the fixing means 11 having the slot. It is fixed by fixing the rotation of the means 10. The angle of inclination of the U-shaped member 7 with respect to the frame 1 can be adjusted by screw means 10 so that it can be changed when the type of workpiece 4 changes.

The U-shaped member 7 has a guide 21 with respect to the frame 1.
It is slidable relative to the guide 21 so that its position in the vertical direction can be adjusted along the inclination.
The handle 13 is a means for adjusting the vertical position of the U-shaped member 7 with respect to the guide 21, and is rotatably supported on the U-shaped member 7 side, and the threaded portion 14 rotated by the handle 13 is attached to the guide 21 side. The inclined vertical position of the U-shaped member 7 with respect to the guide 21 can be adjusted by screwing it into the female screw means 15 and changing the screwing position between the screw portion 14 and the female screw means 15. . The reason why the inclined vertical position of the U-shaped member 7 is adjustable is to make the position of the U-shaped member 7 correspond to the change in the type of workpiece 4 flowing on the line.

A punch mounting base 16 is provided on the U-shaped member 7 so as to be slidable with respect to the U-shaped member 7. The punch mount 16 is arranged between the upper jaw 5 and the lower jaw 6,
It slides with respect to the U-shaped member 7 with the same inclination as the U-shaped member 7.

A punch 17 is removably set on the lower end of the punch mount 16. The punch 17 is used to punch a valve hole in the rim wall 4a.

A stripper 18 is attached to the punch 17 so as to be slidable on the punch mount 6 (see FIG. 2), and the stripper 18 is urged downward by a spring 19. The stripper 18 is provided to separate the workpiece 4 from the punch 17 after drilling the valve hole.

A cylinder 20 is attached to the upper jaw 5 to slide the punch mount 16 relative to the U-shaped member 7 in the direction of inclination of the U-shaped member 7.
The tip of the rod 20a that appears is the punch mounting base 1.
6 and moves in the direction of the rim wall 4a of the workpiece 4.

Next, the operation in the above embodiment will be explained.

The disk wheel 4, which is a workpiece, is horizontally inserted into the valve drilling device with its axis oriented in the vertical direction and laid down on its side. Since the disk wheel 4 is carried in horizontally, it can be carried into the valve drilling apparatus by sliding it in the horizontal direction on a horizontal stand (not shown) provided near the valve drilling apparatus. During horizontal conveyance, the work 4 does not slide on the table due to its own weight, making the insertion work easier. The workpiece 4 is pushed in by hand until it hits a stopper (not shown) of the valve drilling device.

After the workpiece 4 is carried between the upper jaw 5 and lower jaw 6 of the U-shaped member 7, the cylinder 20 is driven to move the punch mount 16 diagonally downward, in the direction of inclination of the U-shaped member 7. The punch 17 attached to the punch mount 16 first comes into contact with the valve hole drilling position of the rim wall 4a. At this time, the contact angle of the punch 17 with respect to the rim wall 4a is perpendicular to the rim wall 4a. When the punch mount 16 is further driven downward by the cylinder 20, the U-shaped member 7 is then slid obliquely upward relative to the guide 21, and the lower jaw 6 of the U-shaped member 7 is inclined relative to the workpiece. Lifted upwards. Rim wall 4 of lower jaw 6
Since the a contact portion 6a protrudes upward in the shape of a bird's beak, it does not interfere with the flange wall of the rim 4a, and the punch 17 at the valve hole drilling position of the workpiece
and come into contact with the opposite side. Furthermore, by driving the cylinder 20, a valve hole is bored in the rim wall 4a held between the punch 17 and the lower jaw 6.

When the drilling is completed, the cylinder 20 is driven in the opposite direction, and the U-shaped member 7 moves obliquely downward, and the lower jaw 6 first separates downward from the rim wall 4a, causing the U-shaped member 7 to move downward.
returns to its original position, and then the punch mount 16 separates from the workpiece, lifts upward, and returns to its original position.
At this time, the stripper 18 is biased by the spring 19 to separate the workpiece 4 from the punch 17. The workpiece 4 in which the valve hole has been bored is taken out by hand in the horizontal direction from the valve drilling device, and the next disk wheel is inserted. After that, the above work will be repeated.

[Effect of idea]

When using the disc wheel valve drilling device according to the present invention, the U-shaped member having the upper and lower jaws into which the disc wheel as the workpiece is inserted can be tilted with respect to the frame via the guide, so that By setting the inclination of the member by the angle that the rim wall at the valve drilling position where the valve hole is drilled makes with respect to the disc wheel axis, the disc wheel can be attached to the valve drilling device to align the disc wheel axis in the vertical direction. The valve can be carried horizontally in a state where it is laid down, and in this state, the valve hole can be punched without slipping against the rim wall by applying the punch at right angles to the rim wall. This horizontal loading and unloading makes it easier to handle the workpiece, making valve hole drilling work much easier and smoother than the conventional method of manually loading and unloading the workpiece diagonally into the press. . For this reason, the conventional wheel manufacturing line requires two
The work that used to be done by placing two presses and one person on each press can now be changed to having two valve drilling machines of this invention installed on the wheel production line and handled by one person. It is possible to save labor and improve efficiency.

In addition, even if the type of workpiece changes, the position of the slide base relative to the bottom of the frame can be adjusted in the horizontal direction, the inclination angle of the U-shaped member relative to the frame can be adjusted, and the angle of inclination of the U-shaped member relative to the frame is adjustable. By being able to adjust the vertical position,
