Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a component drilling device capable of sequentially and in large quantities punching small components having a certain shape in succession.

[0002]

[Prior Art]

 Conventionally, as a device for punching vertical holes 17 on the same circumference of a cap portion 16a of a cylindrical cap-shaped component 16 as shown in FIG. 3, a turntable that intermittently rotates by a predetermined angle is used. The parts were fixed to the outer circumference of this turntable, and the drills for drilling were fixed at each stop position of the turntable. In this conventional device, it is necessary to stop the turntable according to the number of parts to be drilled and install a drill at each stop position, which requires a large amount of equipment and requires a great deal of setup work prior to machining. There was a problem that it took time and effort.

In view of this, the inventors have previously disclosed in Japanese Utility Model Application Laid-Open No. 2-61515 that a component is intermittently moved by a conveying rail for a predetermined distance, and a spindle that moves up and down between the conveying rails at a stop position of the component is used. We proposed a drilling device that supports a component from below and drills it while the spindle is rotated at a desired angle while the component is stopped.

[0004]

[Problems to be solved by the device]

 As described above, in the case of forming a vertical hole in a cylindrical part, the above-mentioned proposal can be sufficiently dealt with, but as shown in FIG. 4, holes 17 having different inclination directions are obliquely formed in the cylindrical part 16. In the case, or when the holes 17 having different inclination directions are crossed for drilling, it is necessary to radially install the two drills 52 so as to face each other.

However, in this method in which two drills are opposed to each other and are radially installed, there are problems that the size of the device becomes large and the device becomes complicated. The present invention has been made to solve the above-mentioned problems when a hole having different inclination directions is obliquely formed in a cylindrical part or when holes having different inclination directions are crossed. An object of the present invention is to provide a component drilling device that can freely drill holes with different inclinations by processing from one direction.

[0006]

[Means for Solving the Problems]

 The component punching device of the present invention has two chucks which can be freely horizontally rotated by a desired angle and which have a chuck device for fixing a component at the center of rotation thereof and which are fixed at the same height and at a predetermined interval. A turntable, a drill for obliquely drilling parts fixed to the turntable, and a part to be sequentially supplied to a position equal to the interval between the two turntables on an extension line connecting the two turntables. And a reciprocating plate which is mounted laterally in parallel with a line connecting the two turntables and which reciprocates a length equal to the interval between the two turntables, and is fixed to the reciprocating plate. And a first cylinder for gripping the component at the component supply position and transferring the component to one of the turntables, and being fixed to the reciprocating plate and perforated with one of the turntables. It consists of a second cylinder that grips the product, reverses it, and transfers it to the other turntable, and a third cylinder that is fixed to the reciprocating plate and grips and takes out the component punched by the other turntable. That is the summary.

[0007]

[Action]

 The component supply device sequentially supplies components one by one to a position equal to the interval between the two turntables on the extension line connecting the two turntables. The reciprocating plate is attached laterally in parallel with the line connecting the two turntables and reciprocates a length equal to the distance between the two turntables. On this reciprocating plate, three cylinders having a gripping mechanism at the tip are attached toward the turntable.

The first cylinder advances at the return stop position of the reciprocating plate to grip the component at the component supply position, and after the reciprocating plate has moved forward, grips at the reciprocating plate forward stop position. Release the part to transfer it to one of the two turntables. When the first cylinder that has transferred the parts to one of the two turntables retracts, the reciprocating plate moves back.

The component placed on the turntable is fixed to the center of the turntable by a chuck device, and the turntable is rotated to a desired position and the drill is moved up and down to move the component from one side to a predetermined position. Perforation is performed.

When the predetermined perforation on the turntable is completed, the second cylinder advances at the return stop position of the reciprocating plate and grips the part perforated from one side on either one of the turntables. When the reciprocating plate is moved forward, the axis of the second cylinder rotates to reverse the gripped part. At the forward stop position of the reciprocating plate, the gripped part is released to transfer the reversed part to the other turntable. When the second cylinder that transfers the parts to the other turntable retracts, the reciprocating plate moves back.

The component placed upside down on the other turntable is fixed to the center of the turntable by the chuck device, and the other component is rotated by turning the turntable at a desired angle and raising and lowering the drill. Drilling is performed from one surface to a predetermined position. As a result, diagonal holes having different inclination directions are cross-drilled in the component.

The third cylinder moves forward at the return stop position of the reciprocating plate to grip the component on the other turntable, and after the reciprocating plate is moved forward, the forward stopping of the reciprocating plate is stopped. At the position, release the grasped part and take out the perforated part on the turntable. When the third cylinder that has transferred the parts retracts, the reciprocating plate moves back.
