DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for fastening a rubber bush at a set position of a cable or the like, and an apparatus which can be suitably used for the fastening work. In the field of vehicle braking, even when sudden braking is applied on slippery roads, the wheels are difficult to lock, and the computer is used for an anti-lock brake system that effectively controls the brake, and a speed sensor and a computer, or an actuator and a computer Etc. are employed as cables for electrically connecting the electronic devices. As the cable, a coaxial cable or the like is used so that the computer does not malfunction due to noise disturbance from the vehicle itself or from outside, and a rubber bush is fixed to each set position on the cable due to wiring. .

[0002]

2. Description of the Related Art Conventionally, in order to fix a rubber bush to a cable used in the above-mentioned anti-lock brake system, first insert the tip of a fixing jig into an insertion hole of the rubber bush, and then, fix the jig. Then, the insertion hole is pushed out to insert the cable, and then the fastening is positioned and the insertion hole is narrowed, while the tip of the jig is removed from the rubber bush, and the rubber bush is stopped at the set position of the cable. I was trying to wear it. In addition, in the above-mentioned fastening work, the diameter of the rubber bush is set slightly smaller than the diameter of the cable to be used, so that the cable and the rubber bush are securely fastened. However, fixing the rubber bush, which is long in the insertion direction, has been a very difficult task even with the above jig. Therefore, an adhesive such as a bond is applied between the rubber bushes with respect to the diameter of the cable so that the rubber bush can slide on the cable by applying a relatively large force by hand, and the cable bush is easily stopped. In some cases, the method was used.

[0003]

In the method of fastening a rubber bush at a set position of a cable according to the above-mentioned prior art, the rubber bush is manually set with a fastening jig. Since the fixing is performed according to the position, the productivity is extremely low. In addition, even in the work using the fixing jig, it is very difficult to fix the rubber bush, which is particularly long in the insertion direction, and there is a disadvantage that productivity is further deteriorated.

[0004] On the other hand, in the simple method described in the section of the prior art, in which the diameter of the insertion hole of the rubber bush is substantially the same as the diameter of the cable, the fastening is performed with time. Due to the weather resistance of the rubber bush, the adhesive strength of the adhesive between the cable and the rubber bush is reduced, the fixing by the rubber bush is not effective, and the cable can be loosened unnecessarily, and a protrusion such as a road surface during running of the vehicle. In addition, there is a disadvantage that the slack portion of the cable is caught and the cable is cut.

Therefore, the present invention has been made in view of the above-mentioned drawbacks and the like, and an object of the present invention is to make the diameter of the insertion hole of the rubber bush, which is a fixing member, slightly smaller than the diameter of a cable or the like. Even if the rubber bush contains a rubber bush that has a length in the insertion direction, which has been difficult with conventional fastening jigs, even if the rubber bush It is an object of the present invention to provide a method that can easily attach bushes at once to a set position of the cable or the like without error, and an apparatus that can be suitably used in the method.

A movable mounting frame provided with fixing means, clamping means for clamping the fixed mounting frame and the movable mounting frame, and a vertical height position of the shaft tube which is erected from the base plate when the shaft tube is maximally pushed out; Carried on Both of them are constituted by a clamping mechanism consisting of a guide holding plate which abuts a fixing member previously fixed to the end of the cable or the like and anchors the cable or the like. The shaft tube of the sliding mechanism is mounted in the clamping mechanism. The gist of the present invention is that it is arranged so as to penetrate through one or more bush insertion holes one after another.

Secondly, the method of fastening a rubber bush according to the present invention is directed to an apparatus for fastening a rubber bush as described in the above aspect, in which the type and the mutual distance of the rubber bush are set initially. Mounting a split mold and a split mold on the fixed mounting frame and the movable mounting frame, respectively, and adjusting and fixing the split mold and the split mold to the set positions by adjusting fixing means provided on the both mounting frames. A step of immersing a rubber bush in a water tank portion in which an aqueous solution of a surfactant in the fixed mounting frame is stored, and a step of removing the rubber bush from the water tank portion and corresponding to the recesses of each of the lower molds of the fixed mounting frame. A step of mounting a rubber bush, and then a step of closing the fixed mounting frame and the movable mounting frame, and holding the mounting frames by holding means. The actuator is actuated to extrude the shaft tube with the cap member attached at the end, and the rubber bush clamped between the fixed mounting frame and the movable mounting frame penetrates one after another to stop pushing the shaft tube to the maximum. And inserting the cable or the like from the other end of the cable or the like to which a fixing member is fixed in advance at one end from the distal end opening of the shaft tube from which the cap member has been removed, and then the actuator Re-actuating the shaft tube to pull back the shaft tube from the rubber bush that has penetrated, releasing the fixed mounting frame from the movable mounting frame and releasing the rubber bush to the set position.

[0008]

First, a cap member having a tapered end and a substantially conical shape is attached to the end of the shaft tube according to the present invention in the pushing direction, and a rubber bush is inserted through the shaft tube. Since the aqueous solution of the surfactant is attached to the holes, the frictional resistance at the time of penetration by the shaft tube is suppressed and the penetration is facilitated.

Next, when an aqueous solution of a surfactant is used, the fastening position of the rubber bush can be shifted by applying a relatively large force at the beginning of fastening, but the product is left after the fastening operation. In the meantime, the aqueous solution of the surfactant is dried, and after the drying, the rubber bush cannot be disengaged even if a force is applied.

Further, when a cable or the like is inserted into the shaft tube and the shaft tube is pulled back, a fixing member fixed to an end portion of the cable or the like is formed so as to contact the guide holding plate. Therefore, the cable and the like are not pulled back together with the shaft tube, but are anchored to the guide holding plate. On the other hand, since the rubber bushing to be fixed is clamped at a predetermined position, only the shaft tube is pulled out. Thereby, each rubber bush acts so as to be fixed to the set position of the cable or the like.
