Description

Detailed Description of the Invention (Field of Industrial Application) The present invention relates to, for example, a hose fitting crimping device and a hose fitting attachment device used in the device, and more specifically, to a hose fitting attachment device used for the device, and more specifically, as a hose fitting crimping device and a hose fitting attachment device for use in the device. A hose fitting crimping device that attaches a hose fitting such as a terminal fitting or a hose intermediate holder to the end of a flexible pressure-resistant hose used for connection to other components, and crimps and secures the hose fitting. and a hose fitting attachment device used in the device.

(Prior Art) A conventional hose fitting crimping device pushes out a tapered ring 201 forward via a pressing means 203, and is disposed in front of the tapered ring 201, as shown in FIG. 12(,), for example. The plurality of clamping claws 205 are guided by the inner peripheral surface 202 of the tapered ring 201 and moved to the center in the radial direction. Tighten 208 and attach hose fitting 2
07 and the hose 209. The pressing means 203 moves back and forth within the cylinder 211 and presses the tapered ring 201 by protruding the tip of the rod 213 from the end surface of the cylinder 211. piston 2
There is one consisting of 15.

According to this conventional example, since the rear of the tapered link 201 is not blocked, the end of the hose or the sleeve of the intermediate holder can be crimped and fixed to the hose regardless of the hose fitting or the length of the hose.

(Problem to be Solved by the Invention) However, in such a conventional hose metal fitting crimping device, a tightening ring 201, a cylinder 211, and a The piston 215 is connected to each tightening claw 205
Since the clamping claws 205 are sequentially arranged on the rearward extension of the center of the clamping claws 205, there is a problem that the entire device becomes larger in the direction of the central axis of the clamping claws 205.

In addition, if the hose fitting is significantly bent, not only the outward radial direction is restricted by the taper ring 201, cylinder 211, piston 215, etc., but also the tightening claw 2
Since the opening amount of 05 cannot be made too large, the hose fitting cannot be set. For this reason, there was a problem in that restrictions were imposed on the shape of the hose fitting 207.

A hose fitting crimping device has been proposed that solves this problem and is capable of crimping even irregularly shaped hose fittings such as those that are significantly bent (Japanese Patent Publication No. 1-3861).
(See Publication No. 8).

As shown in FIG. 12(b), the tightening pawl 221 is attached to a die holder 223, which is divided into left and right parts, and screws 225 are attached to the die holder 223.
The die holder 223.223
are symmetrical to each other, each having a semi-circular recess 227 and 227 to prevent the hose from being caught when butted against each other, and each has a sliding groove 231 formed on the lower surface to fit with the rail 229, Furthermore, a die holder 223.2 is attached to the side of each die holder 223.223.
The rod 22 of the hydraulic cylinder 233 that serves as a means of moving the rod 23
5 are connected and fixed.

When using the hydraulic cylinder 233, first
．． 233 to separate the die holders 223 and 223, and insert the hose fitting into the insertion hole 239 of the front flange 237.
Insert from. Thereafter, the hydraulic cylinders 233, 233 are operated to bring the die holders 223, 223 together.

Then, as in the past, the tightening claw 221 is tightened by tapering.
It is crimped by moving it toward the center in the radial direction.

However, although the insertion hole of the die holder is enlarged by dividing the die holder into left and right sides, the insertion hole 239 of the front flange 237 is not enlarged, and the hose fitting must be inserted and set through the insertion hole 239. There is a problem in that it is difficult to insert metal fittings with large bends.

Further, the insertion of the hose fitting into the hose fitting crimping device and the attachment of the fitting to the end of the hose are all performed manually. That is, the hose fitting 207 is attached to the end of the hose 209.
The series of steps for installing the hose is performed in the following order: first manually inserting one hose fitting 207 into one end of the hose 209, then inserting the other hose fitting 207 into the other end, and then adjusting the mounting angles of both fittings. It was always done by hand using tools. Then manually attach the hose fitting to the center position of the crimping claw of the crimping device.
Then, caulking is performed. In this way, the hose fitting 20
All steps except the crimping step in step 7 were done manually using tools.

However, most of the conventional fixing work of the hose fitting 207 relies on manual labor, which not only makes the work complicated and inefficient, but also causes severe worker fatigue. There was a problem in that the work required skill to maintain quality.

On the other hand, the movable clamp 143 has the same structure as the fixed clamp 141, and is fixed at a position a predetermined distance from the end of the hose 83 by a hydraulic circuit (not shown).

Next, the effect will be explained.

In the above configuration, the bent hose fittings are attached to both ends of the straight hose 83 in the following manner.

First, sleeves are inserted into both ends of the straight hose 83, and the hose 83 is placed between the fixed bodies 165 on the first movable table 87. By driving the hydraulic circuit, the hoses are sequentially connected to the fixed clamp 141 and the movable clamp 143. 83
fixed, and the sixth and seventh movable tables 133.13
5, bent first and second hose fittings 12 with nipples inserted into the ends for fixing to the ends of the hose 83;
9.131 are each fixed in such a way that their nipples are located on the axial extension of the hose 83.

Thereafter, the second motor 115 is driven to move the fourth movable table 113 toward the first movable table 87, and after the nipple of the first hose fitting 129 butts against the sleeve of the hose 83, the third motor 137 is driven. Then, the nipple of the first hose fitting 129 is inserted into the hose 83 by moving the sixth movable table 133 toward the first movable table 12-pull 87.

By moving the seventh movable table 135 toward the first movable table 87, the outer cylinder of the second hose fitting 131 is inserted into the hose 83.

Next, the hose 83 is released from the fixed clamp 141 and the movable clamp 143 by driving the hydraulic circuit, and then the first movable table 87 is lowered by driving the cylinder 85. As a result, the hose 83 is located in the air, and the sixth and seventh movable tables 133.
When the hose fittings 129 and 131 supported by the hose fittings 135 are inserted, they are positioned in a direction parallel to the center line of the insertion hole of the tightening claw 43 of the hose fitting tightening device 1.

Then, by driving the first motor 105, the first
The second and third movable tables 97.99 move in a direction perpendicular to the axial direction of the hose 83 via the second screw shaft 93.95, and the hollow hose 83 is tightened by the hose fitting crimping device 1. After being positioned on the center line of the attached claw 43, the first hose fitting 1 is moved by driving the second motor 115.
The sleeve No. 29 is positioned at the center of the tightening claw 43.

Since the cut plane between the movable unit 21 and the fixed unit 19 is formed lower than the horizontal line passing through the center of the tightening claw 43 on the hose insertion side, the fitting can be tightened simply by moving the hose in the horizontal direction. It can be positioned in the center of the attachment claw.

In this state, by driving the cylinder 15, the movable unit 21 descends and comes into contact with the fixed unit 19,
The pins 25.25 are fitted into the bottle boulders 27.27 to unite them. Further, when the cylinder 69 is driven and the rod 71 is contracted, the rotating disk 49 and the cam disk 53 are integrally rotated in the counterclockwise direction in FIG. 1 with respect to the cam disk support plate 9. The abutting pin 80 abuts against the stopper 79 and stops.

Thereafter, by driving the second motor 115, the sleeve of the second hose fitting 131 is positioned at the center of the insertion hole of the tightening claw 43, and the cylinder 15 is driven to move the movable unit 2.
1, and again put the pins 25 and 25 into the pin holder 27.
．． 27 and comes into contact with the fixed side unit 19. Further, when the cylinder 69 is driven and the rod 71 is contracted, the sleeve of the second hose fitting 131 is crimped and fixed to the end of the hose 83 in the same way as described above, and when the cylinder 69 is driven and the rod 71 is expanded, it is tightened. The attached claw 43 returns to its initial position.

Then, by driving the cylinder 15, the movable unit 2
1 is raised and separated from the fixed side unit 19, and the first motor 105 is driven to move the second and third movable tables 97.99 to the hose fittings via the first and second screw shafts 93.95. It moves away from the tightening device 1, and then the fourth and fifth
The movable tables 113 and 119 are moved in the axial direction of the hose 83 and returned to the initial position. After that, cylinder 85

Even if the hose fittings 129, 131 have complicated shapes such as, the entire device 5 can be set and crimped without interfering with the fittings, and the restrictions imposed on the shape of the hose fittings can be greatly alleviated. can.

In addition, the straight hose 83 is fixed on the first movable table 87, and the first
The process of fixing the second hose fitting 129, 131 to the end of the hose 83 can be performed automatically by simply fixing the second hose fitting 129, 131 and operating a switch (not shown), making the work easy. This not only improves work efficiency, but also makes quality uniform and improves the reliability of crimping.

Note that the present invention is not limited to the above-mentioned embodiment, and for example, instead of providing the clamping claw return plate 61 in which an elongated hole 63 is formed as the clamping claw return means, a spring that biases the clamping claw 43 itself outward may be used. A similar effect can be obtained by using a configuration in which .

(Effects of the Invention) As explained above, according to the present invention, the clamping pawl that is slidable in the radial direction of the hose with respect to the cam disc support plate on the fixed side is provided circumferentially with respect to the cam disc support plate. Since the configuration is such that the cam of the cam disc rotates in the radial direction of the hose presses against the radial center of the hose, the entire device can be made more compact, and the restrictions imposed on the shape of the hose fittings that can be set are greatly eased. Even hose fittings with large bends can be tightened.

In addition, the cutting plane between the movable unit and the fixed unit is provided horizontally, and is lower than the horizontal line passing through the center of the tightening claw on the hose insertion side, so you can easily move the hose horizontally. The hose fitting can be placed in the center of the clamping claw.

Furthermore, a series of steps for fixing the hose fitting to the end of the hose can be performed automatically, improving work efficiency, making quality uniform, and improving the reliability of crimping.
