Next, insert the tenor into the spider shaft using the tenor circlip insertion device described above.

I will explain my previous work when detecting the position of a circlip.

First, the spider shaft of the spider with the retainer and the f-clip pushed into it is set at the measurement position, and when the axis of the spider shaft and the axis of the center bin at the insertion agi position are aligned, the cylinder tat is extended in this state. Then,
The slider body direction, which is connected to the piston rod arm of the cylinder (toward) through the 70-con end, rod 4, and spring Wt, moves forward, and first, the front wall (221L
) The tip of the center bin (which is supported by the inner cylinder fixed to the inner cylinder via a spring) fits into the recess formed at the tip of the spider shaft, and the entire positioning of the spider shaft is performed.
Next, the ball holding jig comes into contact with the width side of the ball and presses the @ side of the ball against the base of the spider shaft. In this state, the cylinder further extends and the guide JQi moves forward together with the advancing stopper, and the retainer detection head and the clip detection head υ come into contact with the retainer and the circlip. Furthermore, this 1. time,

When the surface comes into contact with the ball scene and the forward movement of Paul Oshimi Osamu stops, only the rod gull connected to the cylinder while the rear (・Gospring wt-a:m) is inside the Stida body prisoner.
- When the cylinder moves forward and the cylinder extends to a predetermined amount, the cylinder's previous extension stops and the cylinder moves to the side.
When the extension operation of the ball presser jig 4, the tenor detection head and the de-clip detection head c4N press against the ball (f) and the retainer (circlip (8)), this The positions of the tenor detection head and the circlip detection head 311 relative to the slider body are measured using the gold dial gauge 14 [1t41], and the positions of the tenor and circlip, based on the width of the ball, are t″lI1 foot. I can do a lot of things.

When the position measurement of the retainer and circlip is completed as described above and the cylinder 1 starts the shortening operation t-g, the cylinder piston rod 27 and 70 cone 2
Only the rod noodle connected through at- slides inside the slider body mouth to the right in the figure. Next, when the rod base slides a certain amount to the right, it is fixed to the rear end of the rod base. (to) comes into contact again with the stopper 4 fixed between the guide rods, and in order to press the guide rod (to) Wt to the right, the guide rod (to) Wt is connected to the F rod mm and the tenor detection head - warped clip detection head ( illll starts to retreat t-n.Then, the rod noodle further slides to the right in the figure, and when the stepped part of the rod base ($15&) and the slider body punishment step @ (f12ri) come into contact, the slider body punishment also occurs. Retraction t- starts, and the ball holding jig t υ fixed to the slider body also starts retracting, causing the entire bag to begin retracting.Then, the cylinder shortens to a predetermined position, and the cylinder shortening operation stops. Then, the ball holding jig, the retainer detection head, and the circlip detection head return to their original positions, and the measurement operation ends.

As explained above, the retainer circlip insertion confirmation device according to the present invention has one width surface [press contact] of a highly precisely machined ball with the end face located at the root of the spider shaft that is machined with high precision. At this time, the position of the other side of the ball is used as the measurement standard, and the position of the retainer and date clip on the spider shaft is measured by inserting it into the spider shaft and adding the position of the tenor and day clip with high precision. can do.

In addition, since this mounting can be inserted into the spider shaft or measured when attaching the tenor and circlip, it is possible to check whether the retainer and circlip have been inserted during the spider assembly process. and whether they are inserted in the correct positions can be checked with high efficiency.

Furthermore, since the device according to the present invention is all driven by one cylinder, the structure is extremely simple.
Maintenance and inspection become much easier.
