This invention relates to a detection device.

検出誤りが生じる欠点を有していた。 Conventionally, as shown in FIG. 1, an annular groove d is formed on the outer peripheral surface of the lip part c of an annular body b made of a rubber-like elastic material, and the lip part c is formed in the annular groove d.
The oil seal a fitted with a garter spring e that tightens the oil seal a is widely known and widely used.
When inspecting the product to see if the garter spring e is properly fitted into the annular groove d,
Conventionally, this has been done by relying on visual inspection by workers (Figure 1) or by indirect detection methods using metal detectors such as photoelectric switches (Figure 2) and proximity switches (Figure 3). It's summery. However, according to this conventional method, inspection errors may occur during visual inspection due to worker fatigue or illusions, and the photoelectric switch f may be affected by external light such as sunlight or illumination. Furthermore, the metal detector g has the drawback that detection errors occur due to detection distance setting errors of the detector g and detection sensitivity errors due to the type of garter spring e material.

ものである。 In view of the above points, the present invention aims to improve detection accuracy, and includes a first detection pin attached to a grounded device body, and a first detection pin attached to the device body via an insulator. The oil seal has a second detection pin and a spring presence/absence detecting means connected to the second detection pin, and is fitted to the lip portion of the oil seal depending on the presence or absence of electricity due to the contact of both of the detection pins with the garter spring. a detection shaft that is fitted into the device main body so as to be movable in the axial direction and has a first contact at one end in the axial direction; and a spring position detecting means connected to the second contact, and the device is fitted in an incorrect position in the axial direction when the main body of the device is brought close to the oil seal. The spring detection device is configured such that the detection shaft moves relative to the main body of the device by a garter spring to bring the two contacts into contact with each other, and detects incorrect fitting of the garter spring based on the presence or absence of electricity accompanying the contact. This is what we intend to provide. In the above configuration, the second half of the incorrect fitting detection section detects whether a part of the garter spring e has come off the annular groove d and is in a state of being shifted in the axial direction (a so-called half-fitting state). It detects whether

In addition, the gap A between the first and second contacts 17 and 22 in the normal state shall be maintained at 0.5 mm≦A≦φD (φD: winding diameter of garter spring e (Fig. 8)), and both The distance B between the detection pins 5 and 7 is matched to the diameter (φD) of the garter spring e (FIG. 8). For inspection, the oil seal a is placed in a position directly below the axis of the detection shaft 16 of the detection device, and the detection device is located slightly above the leading edge of both detection pins 5 and 7. The protruding shaft 16 is lowered to a height such that the lower end surface of the pusher 18 contacts the lip portion e of the oil seal a. The detection operation of the detection device is classified as follows depending on the state of the oil seal a, which is the object to be detected.

する。(a) When the garter spring e is fitted in the correct position (Fig. 5) Push contact 1 of the detection shaft 16 at the lower stroke limit
The ends of both detection pins 5 and 7 protruding further downward from the lower end surface of 8 contact the garter spring e, and the energization caused by this contact is confirmed by the spring presence/absence detection means 15, and the detection shaft 16 etc. The normal fitting of the garter spring e is confirmed by detecting the inoperation of the improper fitting detection section. That is, both detection pins 5 and 7
First, the fact that the garter spring e is fitted is detected by the conduction between the garter springs e, and it is confirmed that the garter spring e is fitted in the correct position by confirming that the incorrect fitting detection section is not activated. Prove.

ることが判明する。(b) When the garter spring e is in a so-called half-latched state (Fig. 9) As shown in the enlarged view in Fig. 4, the garter spring e shifts upward in the axial direction from its normal fitted position, resulting in a so-called half-hung state. , the pusher 18 of the detection shaft 16 that has been gradually descending comes into contact with the garter spring e and is stopped from descending before the entire detection device stops descending, and the elasticity of the coil spring 21 The first and second contacts 17, 22 begin to move upward relative to the device main body 1, which continues to descend against the
Since the gap A between the two 17 and 22 is smaller than the winding diameter (φD) of the garter spring e, they come into contact with each other. By detecting the energization caused by this contact with the spring position detection means 23, it is determined that the garter spring e is in a half-loaded state.

精度を向上させることができるものである。 The spring detection device applies a voltage to the entire device, and directly connects the first and second detection pins 5, 7 and the push contact 18 of the detection shaft 16 to the garter spring e.
Since the configuration detects the presence or absence of the garter spring e and whether it is fitted or not based on the presence or absence of electricity caused by the contact, it eliminates detection errors caused by human error or changes in external factors as in conventional methods, and improves detection accuracy. This is something that can be improved.
