Description

[Detailed Description of the Invention] <Industrial Field of Application> The present invention relates to a device for adjusting the angle of a mouthpiece before press-fitting and fixing the mouthpiece to a hose.

<Prior Art> Conventionally, a brake hose (hereinafter referred to as a hose) as shown in FIG. 6 has been used as a hose for transmitting hydraulic pressure to the brakes of an automobile. This hose 11 has a hose cap 12 and a hose cap 13 attached to both ends thereof, and an intermediate cap 14 attached to a middle portion of the hose body 15.

By the way, when installing this hose to the car body,
In order to avoid interference with other parts, its length is determined to be the minimum necessary length. Furthermore, if the hose is installed in a twisted manner, there is no extra length, and more stress than necessary will be applied to the hose. Therefore,
The mounting angles of each hose cap and intermediate fitting are precisely determined.

In manufacturing this hose, the hose bodies 15 are inserted from both sides of the intermediate fitting 14, and after both sides of the intermediate fitting 14 are caulked by a caulking machine, the hose caps 12 and 13 attached to both ends are caulked. It is set at a predetermined angle inside the caulking machine.

In order to accurately attach the hose caps 12 and 13, the outer shape is approximately rectangular, and each hose cap 12 and hose cap 1 are provided inside the hose cap 12 and hose cap 1.
The hose cap 12 and the hose cap 13 are set in a metal angle adjustment jig that is divided into upper and lower parts and has a recess corresponding to the shape of 3 and an insertion portion for the hose body 15 on the hose body insertion side. , which are inserted into each end of the hose body 15.

After that, the hose cap 12 and the hose cap 13 are caulked. An operator manually sets the hose caps 12 and 13 on the angle adjustment jig each time.

<Problems to be solved by the invention> If the above process is performed mechanically, it is possible to detect the angle of the hose fitting by image processing and insert it into the hose based on this. In the method of receiving the information with a camera, calculating the angle with an image processing device, and inserting this into the hose with a robot hand, etc., the image processing device requires a large amount of cost, and furthermore, the device for inserting the hose cap into the hose is required. Since it requires high precision, it becomes expensive.

<Means for Solving the Problems> The mouthpiece angle adjusting device of the present invention includes a mouthpiece receiving part that rotatably holds a mouthpiece having a mouthpiece pin;
An angle adjusting member is provided on the side of the cap that has the cap pin, is movable back and forth, has a substantially claw-like shape with an acute tip when viewed from above, is approximately Σ-shaped when viewed from the side, and has a bottom portion that the cap pin comes into contact with when the angle adjustment is completed. I took it as a thing.

<Operation> In the mouthpiece angle adjusting device of the present invention, a hose mouthpiece having a mouthpiece pin is placed on the mouthpiece receiving part so that the mouthpiece pin is on the side of the angle adjustment part, and the angle adjustment member is advanced by the cylinder. Then, the cap pin comes into contact with a part of the angle matching portion, and as the cap pin moves forward, the hose cap rotates along the shape of the angle matching portion. When the angle adjusting member reaches the most advanced position, the base pin comes into contact with the bottom of the angle adjusting portion, and the angle of the base pin is set to a required angle.

<Example> Hereinafter, this will be explained in detail using examples.

FIG. 1 shows a hose cap whose angle is adjusted by the device of the present invention.

This hose cap 1 connects a sleeve portion 10 that is connected to a hose body 15 and is caulked, and an eye joint portion 6 that inserts a bolt with a flow path into a bolt insertion hole 8 and connects to a flow path of the equipment body on both sides of a flange portion 9. In preparation for this, the cap pin 3 protruding on both sides parallel to the axial direction of the bolt insertion hole 8 is inserted into the eye joint part 6.
It is formed in the extension part 7 of. The cap pin 3 formed on this extension part 7 engages with a positioning hole formed in the main body of the device to which the hose is connected, and prevents rotation of the joint main body due to tightening of the bolt and maintains a constant connection direction. That is.

Next, the structure and operation of the angle adjusting device for the hose mouthpiece 1 will be explained with reference to FIGS. 2 to 5.

This angle adjustment device is provided with three support parts 2a for supporting the hose mouthpiece 1 at the upper part of the mouthpiece receiving member 2, and a contact part 2b with which the hose mouthpiece 1 comes into contact when adjusting the angle at the rear of the support part 2a. There is. On the side of the hose cap 1 having the cap pin 3, there is a lower portion 5 which is movable back and forth, has a substantially claw-like shape with an acute tip when viewed from above, and is approximately Σ-shaped when viewed from the side, with which the cap pin 3 comes into contact when the angle adjustment is completed. An angle adjusting member 4 having a diameter is provided. This angle adjusting member 4 is configured to move back and forth by a cylinder (not shown) at the rear thereof.

The operation of this device is such that when the hose cap 1 is placed on the cap receiving member 2, the angle adjusting member 4 moves forward and comes into contact with a part of the cap pin 3, pushing the hose cap 1 backward. Then, the rear end of the sleeve portion 10 of the hose cap 1 comes into contact with the contact portion 2b of the cap receiving member 2. Therefore, as shown in FIGS. 4 and 5, a to d, the base pin 3 begins to rotate in accordance with the shape of the angle adjusting member 4. Then, the angle adjusting member 4 advances until the base pin abuts the bottom portion 5, stops, and retreats to the original position. At this time, the cap pin 3 is adjusted horizontally, and the axial direction of the bolt insertion hole 8 is also horizontal. The hose cap 1 whose angle has been adjusted is chucked, inserted into the hose body 15, and swaged.

In the present embodiment, the mouthpiece pin 3 is adjusted horizontally, but the angle of the angle adjustment member 4 can be arbitrarily set depending on the angle at which the hose mouthpiece 1 is attached.

<Effects> With the above-described configuration, the mouthpiece angle adjusting device of the present invention can adjust the angle of a hose mouthpiece having a mouthpiece pin with a simple mechanism.
