JPS6037209Y2 - Positioning device for workpiece processing unit - Google Patents

Description

[Detailed description of the invention] The present invention relates to a positioning device for a workpiece processing unit, and its purpose is to easily and accurately position multiple points on a straight line using only one mechanical input. That's true.

When drilling holes in a workpiece at multiple points on the same line using a single drill that moves forward and backward, a cylinder device is used to shift the headstock in the left-right direction.

Therefore, a hydraulic cylinder, a directional control valve, and electrical control parts are required, which inevitably leads to high equipment costs and disadvantages in terms of space.

In order to solve the above-mentioned conventional problems, this invention makes it possible to freely position the headstock at multiple points using a cam plate and an arrow guide by using forward and backward feeding movement of the headstock, and uses a dedicated cylinder device and other accessories. The purpose of the present invention is to provide a positioning device that does not require the following.

Embodiments of the present invention will be described below with reference to the drawings.

In the figure, 1 is a fixed table, 2a and 2b are supporting members fixedly installed on the fixed table 1, and these supporting members 2a,
2b, a pair of first
Linear shafts 3a and 3b are fixed.

A movable table 4 is attached to the first linear shafts 3a and 3b.
The first linear shaft 3a is slidably guided and supported on the movable table 4.

A pair of second linear shafts 5 in the Y-Y axis direction perpendicular to 3b are provided, and a headstock 6 is supported by these so as to be freely forward and backward.

That is, a headstock 6 bearing a spindle 7 for mounting a tool 8 on a movable table 4, a motor 19 for rotationally driving the spindle 7, a hydraulic cylinder 9 for moving the headstock 6 forward and backward, and a hydraulic cylinder 9 for moving the headstock 6 forward and backward. Hydraulic motor 11, directional switching valve 12, and hydraulic tank 10 for supplying hydraulic pressure
The drilling unit consists of:

In the above structure, the present invention fixes the cam plate 13 to the support member 2a fixedly installed on the fixed table 1.

This cam plate 13 is provided with a meandering guide groove 14 having positioning recesses G1 to G4 corresponding to the positions of multiple holes H1 to H4 on the same line to be drilled in the workpiece W. An arrow guide 16 is pivotally attached to each protruding end 15 of the groove 14 by a pivot pin.

Furthermore, an operating rod 17 that protrudes in the direction of the cam plate 13 is fixed to the movable table 4, and a follow bearing 18, which is a guided member guided along the guide groove 14, is attached to the operating rod 17. It is being

Next, the operation of the above structure will be explained.

By moving the headstock 6 forward and backward, the hole drilling in the workpiece W is sequentially positioned from hole H1 to H2, H3, H4, . . ., Hn.

In the figure, the headstock 6 is in the retracted position after completing the machining of the hole H1, and moves forward from this position to machine the next hole H2.

That is, as the headstock 6 moves forward, the arrow guide 16 provided at the tip 15 between the positioning recesses G1 and 62 guides the follow bearing 18 to the positioning recess G2.

At this time, the follow bearing 18 comes into contact with the arrow guide 16 provided on the tip 5 facing the positioning recess G2, and the direction of the arrow guide 16 is changed.

The direction of the arrow guide 16 at this time is changed so that when the follow bearing 18 retreats from the positioning recess G2, it is guided to the recess facing the protruding end between the positioning recesses G2 and G3.

When the follow bearing 18 is guided to the positioning recess G2, the headstock 6 is automatically positioned by a shift operation corresponding to the hole H2 to be machined at the same time as the headstock moves forward.

When the machining of the hole H4 is completed by repeating these operations, the next workpiece W is shifted in the opposite direction to the previous workpiece by advancing and retreating the headstock 6, and is sequentially positioned from the hole H4 to Hl. The unit is returned to its original position while making holes on the way back.

As described above, according to the present invention, the direction of the arrow guide guided to the meandering guide groove is automatically changed by the forward and backward movement of the headstock, the headstock is shifted at regular intervals, and the headstock is sequentially positioned at multiple hole machining positions. This eliminates the need for conventional shift-dedicated hydraulic cylinders, directional control valves, electrical control parts, etc., and has the advantage of cost reduction and compactness, as well as reliable positioning without any causes of failure. It has the advantage of being
