Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an inspection device for a brake hose with an intermediate joint fitting.

"Prior Art" Automotive brake hoses are used in hydraulic circuits that are important for safety, so they are commercially available with terminal fittings that have excellent pressure resistance and ease of installation.

Furthermore, in recent years, brake hoses with intermediate joint fittings, in which intermediate joint fittings are attached to the middle part of the brake hose, have been used in order to prevent piping from coming into contact with other automobile parts. FIG. 2 shows an example of this type of brake hose with an intermediate joint fitting.

For such brake hoses with intermediate joint fittings, the shape and installation of the terminal fittings and intermediate fittings may vary depending on the vehicle model.
The mounting angle is strictly determined.

Therefore, when inspecting manufactured brake hoses with intermediate joint fittings, the shapes of the terminal fittings and intermediate fittings, the mounting positions, the mounting angles, and the distance between the terminal fittings and intermediate fittings, etc.
Must be inspected according to this specification.

Conventionally, inspection work for brake hoses with intermediate joint fittings was carried out one by one through visual inspection of these inspection items. However, since brake hoses with intermediate joint fittings are produced in units of tens to hundreds of thousands of pieces per month, the number of inspection steps is extremely large.

[Problems to be Solved by the Invention] The present invention has been made based on the above points, and provides an inspection device for brake hoses with intermediate joint fittings that eliminates the drawbacks of the prior art and significantly improves the number of inspection steps. Our goal is to provide the following.

[Means for Solving the Problems] The gist of the present invention is to provide a rotation mechanism that can rotate in the axial direction up to the permissible limit of the terminal fitting mounting angle, and a rotation mechanism that can rotate a predetermined length from the intermediate joint fitting to the terminal fitting. The apparatus for inspecting a brake hose with an intermediate joint fitting is characterized by comprising a rotary end fitting inspection frame having a spring that can move within an allowable range, and a fixed intermediate joint fitting inspection frame with a closing detection switch.

In the present invention, the fixed intermediate joint fitting inspection frame with a closing detection switch and the rotary terminal fitting inspection frame refer to the shape, mounting position, and mounting angle of the end fitting and intermediate fitting of the brake hose with the intermediate joint fitting to be inspected. is set within the permissible limits. When a brake hose with an intermediate joint fitting is put into this inspection device for inspection, the fixed intermediate joint fitting inspection frame with a feeding detection switch is fixed in the axial direction, and the rotatable terminal fitting inspection frame is attached to the fixed axis. By checking the rotation of the terminal fitting, it is possible to check whether the mounting angle of the terminal fitting with respect to the intermediate fitting fitting is within an allowable range.

[Function] The effect of the present invention is to adjust the shape, mounting position, and mounting angle of the terminal fitting of the brake hose with intermediate joint fitting to be inspected and the mounting angle of the terminal fitting to be within the permissible limits of the mounting angle. A rotary terminal fitting inspection frame having a rotating mechanism that can rotate in the axial direction to an allowable limit range and a spring that can move within a predetermined allowable range of a predetermined length from the intermediate joint fitting to the terminal fitting, and a fixing frame with a closing detection switch. The inspection device for brake hoses with intermediate joint fittings, which consists of an intermediate joint fitting inspection frame, detects the shape and installation position of the end fittings and intermediate fittings by simply inserting the brake hose and rotating it slightly. , it is possible to easily, quickly and accurately check whether the mounting angle is within permissible limits.

[Example] Next, an example of the inspection device for a brake hose with an intermediate joint fitting according to the present invention will be described with reference to the drawings.

FIG. 2 shows an example of a brake hose with an intermediate joint fitting, in which terminal fittings are fixed to both ends of the hose, and an intermediate joint fitting 4 is attached to the middle part of the hose. The terminal fittings include a first terminal fitting 2 connected to the wheel caliper side and a terminal fitting 3 shown in Fig. 2 connected to the brake master cylinder side. In this example, the first terminal fitting 2 is a spectacle-shaped fitting, and the second terminal fitting 3 is a female-type fitting. The intermediate joint fitting 4 consists of an outer cylinder 4-1 and an inner cylinder 4-2, and is fixed by compressing and caulking the outer cylinder 4-1.

FIG. 1 shows an embodiment of an inspection device for a brake hose with an intermediate joint fitting according to the present invention.

In FIG. 1, reference numeral 20 denotes a rotary terminal fitting inspection frame, and in this case, the case of the first terminal fitting 2 is shown. 21 is a predetermined length tolerance (it is a spring that can move back and forth. Although not shown in the figure, this rotary terminal fitting inspection frame 20 has a permissible angle limit for installing the terminal fitting with respect to the hose shaft. Reference numeral 22 denotes a fixed intermediate joint fitting inspection frame, which allows the inspection insertion position and angle to be fixed when a brake hose with an intermediate joint fitting to be inspected is inserted. Reference numeral 23 denotes a detector that detects that the brake hose with the intermediate joint fitting to be inspected has been reliably inserted into the inspection device.

Next, the operation of this inspection device will be explained. First, a brake hose with an intermediate joint fitting to be inspected is put into this testing device, and whether or not it is reliably put in is confirmed by the put-in detector 23. If this can be confirmed, it is confirmed that the shape of the intermediate joint fitting is also appropriate. Further, if the first terminal fitting 2 fits completely into the rotary terminal fitting inspection frame 20, it can be seen that the shape and length of the first terminal fitting are appropriate.

Next, by checking the rotation of the rotary terminal fitting inspection frame 20 slightly, it is inspected whether the mounting angle of the first terminal fitting is within the limit with respect to the mounting angle of the intermediate joint fitting. These inspection operations are easy and can be performed quickly and accurately. Although FIG. 1 shows an example of the inspection of the part including the first end fitting and the intermediate joint fitting of the brake hose with the intermediate fitting, the inspection can be carried out in the same way for the part including the second end and the intermediate fitting. I can do it.

[Effect of the invention] The inspection device for a brake hose with an intermediate joint fitting of the present invention has the following effects:
Although it is an extremely simple device, it can easily, quickly and accurately inspect a brake hose with an intermediate joint fitting, and is industrially useful.
