Abstract

PURPOSE:To aim at simplification and expedition of the setting of works different in each positioning hot position, by installing the plural number of positioning devices, each of which is capable of making a positioning pin come in or out easily by means of a ball locking mechanism and a pin return spring, in work setter. CONSTITUTION:A positioning device B is installed piercedly in a setter body 1 in an orthogonal direction to the surface of the body 1 by a work holding member 4. A guide hole 5 made up through the central part of the member 4 receives the insertion of a positioning pin 3 being slidable. This pin 3 has an engaging hole 6 while it is provided with a guide pin 7 inserted and made up with a flange 10 at the rear end part as well as being energized backward by dint of a spring 11. A ball locking mechanism 13 consists of a ball 15, a slidable operating cylinder 17 and a ball lock spring 18. For retreating the pin 3, it will do when a pusher 21 is thrust in, the cylinder 17 compresses the spring 18 going back thereupon, so that the ball 15 comes off the hole 5, thus the pin 7 stops at the rear end of a braking hole 12 and disappeares from the surface of the member 4.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a workpiece chamber equipped with a positioning device for multiple types of workpieces or objects to be inspected (hereinafter collectively referred to as "workpieces") with different positions of positioning holes. Regarding fittings.

With conventional workpiece mounts, in order to accommodate workpieces with different positioning hole positions, each positioning bin is hinged into the positioning hole position of each workpiece using a screw carved into the bin. Or, the installation has been changed with nuts etc.

However, with such conventional workpiece fixtures, when attaching a workpiece with a different positioning hole position, the positioning pin already attached to the workpiece fixture is removed and the positioning hole of the workpiece is adjusted to the position of the positioning hole. Because the positioning bin was attached with screws, etc., it took a long time to replace the positioning bin, and the work was troublesome, especially for pallet type and transfer mh.
When there are a large number of fixtures, such as when individual workpieces are attached to pallet-type fixtures and sequentially transported to a volume machining process, there is a problem in that it takes an extremely large amount of time for replacement work. was there.

This invention was made by focusing on such conventional problems, and a positioning bin that can be easily put in and taken out with a ball lock mechanism is attached to the positioning hole position of each workpiece in advance with a simple operation. The aim is to solve the above problems by creating and manipulating them.

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

First, to describe the configuration, the wJ1 diagram is 21! This shows the entire (front view) of the workpiece fixture A for the fist workpiece (named 1% deaf), where 1 is the fixture body, 2 is the workpiece, and 3 is the positioning pin, of which a.

b is for work I, and C%d is for work amount. a and b of these positioning pins 3.

As details of the positioning device WtB, which has t and c and d, respectively, are shown in FIG. 5
The workpiece receiver has a guide hole drilled through the center of the member 4, into which a positioning pin 3 is slidably inserted. This pin/8 has a retaining hole 6 cut at a required location in the front part (left side in the figure), and a guide pin 1 is inserted through the center rear part, and 8hfc is inserted from the rear end to *. *F'3k! -,,9Myb
) 8 &"°" 7 The rear end of the positioning pin 3 protrudes to form a boxwood IO, and there is a gap between it and the rear face of the positioning device body 4. There is a pin inserted. Further, the guide pin l slides within a pair of control holes 12 (elongated holes) bored in the main body 4 to regulate the protruding and retracting positions of the positioning pin 8 with respect to the surface of the main body 4. The position of the retaining hole 6 in the circumferential direction is maintained by inhibiting the bin 30 from moving together.

The pole lock mechanism 13 is configured such that the workpiece holder is in contact with a ball 15 accommodated in a ball hole 14 bored in a required location on the inner surface of the guide hole 5 corresponding to the retaining hole 6 and the ball I5. The actuating cylinder 11 is slidably fitted into the actuating hole I6 bored at a required location on the rear surface of the member 4, and the actuating cylinder 1
7 and between the actuating cylinder 1 and the fitting main body 1.
Pole lock spring 1 that always urges 7 forward
It consists of 8. In addition, the operating cylinder 17 has a reduced side surface 19 with a tapered portion 20, and a small-diameter pusher 2.
1 is attached to the front surface, and is slidably inserted into an operating hole 22 penetrating the center of the bottom surface of the operating hole 16 of the pusher 21#i.

Next, the effect will be explained.

FIG. 2(a) shows a state in which the positioning pin 8 protrudes from the end surface of the workpiece holder 4, and the pin 3
To move backward, push hand 2 of pole lock machine #413.
1 is pushed in with a push rod or the like, as shown in Nm-), the actuating cylinder !7 presses the ball lock sleeve 18 and moves backward, so that the ball I5 is pushed into the device of the actuating cylinder 11. 20, and is displaced from the retaining hole 6.Therefore, the pin 〆〆, the tin ring 11 pushes the retainer 1o by the repulsive force ν.
[1] While the positioning pin 8 is being moved and withdrawn, the guide pin 1 slides inside the control hole 12 (7) The guide pin 1 that is retreating stops when it comes into contact with the rear end of the control hole 12, and the position Then, the tip of the positioning pin 3 disappears from the surface of the positioning device main body 40.

Next, in order to project the positioning pin 8, simply push the rear end of the positioning pin 8 using pressure ML of the pin return spring 11 until the guide pin 1 comes into contact with the front end of the control hole 12. The ball 1 is pressed against MIll[i of the positioning pin 3 by the tapered portion 20 of the actuating cylinder 11 which is biased in the forward force direction.
5 engages with the retaining hole 6, and the pin 3#i is fixed.

Therefore, when attaching the workpiece I to the workpiece mount A, the positioning pins a and b are protruded by the simple operation described above, while the positioning pins c and d are retracted, and when the workpiece layer is attached, the positioning pins a, b%c,
The workpiece can be easily positioned by arranging the positions d in opposite positions. Although the workpiece is gripped by a clamp (not shown), the positioning pin 3 may be pushed manually using a push rod or the like, but there is also a method using a cylinder.

As explained above, 1. According to the present invention, the workpiece fixture is equipped with a plurality of positioning devices that can easily insert and remove the positioning pin using a pole lock mechanism and a pin return spring. Since the installation can be carried out quickly, it has a significant effect on saving work time and improving productivity.
Since the operation of inserting and removing the positioning pins has been simplified, there is also the advantage that it can be automated.
