Description

[Detailed Description of the Invention] (Industrial Application Field) The assembly metal fitting fixing jig of the present invention relates to an assembly metal fitting fixing jig used in an assembly machine of a columnar insulator device for bonding insulator metal fittings with cement.

(Prior art) Conventionally, in order to assemble a column-shaped insulator device by bonding an insulator metal fitting to a porcelain insulator with cement, the lower insulator metal fitting was placed horizontally on a surface plate provided on a base, and the cement for bonding was into the lower insulator metal fitting, insert the porcelain insulator into the lower insulator metal fitting, and temporarily fit the bolt hole of the upper insulator metal fitting into the positioning pin of the metal fitting fixing jig provided on the arm that extends horizontally from the column and can be raised and lowered. Adjust the distance between the surface plate surface and the metal fixture fixing surface of the metal fixture fixing jig to the specified dimensions, fix the arm height regulating stopper provided on the column at this height, and then After the adhesive cement had hardened to some extent, it was turned over, the height was determined using the arm height regulating stopper, and the upper insulator metal fitting and this porcelain insulator were cemented together on a surface plate.

(Problem to be solved by the invention) When such a reversing operation is performed, the efficiency of using the assembly machine is poor because the reversing operation cannot be performed until the cement bond between the lower insulator fitting and the porcelain insulator has hardened to some extent. Therefore, the upper metal fitting is temporarily fixed to the metal fitting fixing jig with bolts, and the upper insulating metal fitting and the lower insulating metal fitting are cemented together at the same time, but the heavy upper insulating metal fitting is attached to the metal fitting fixing jig. Temporarily fixing the metal fittings to the metal fittings requires fitting the positioning pins provided on the underside of the metal fitting fixing jig into the bolt holes of the insulator metal fittings, which is both hard labor and dangerous for the workers. It is.

However, if this temporary fixing is not done, the upper insulator fitting will sink while the cement is soft, making it impossible to manufacture the product with high dimensional accuracy.

However, in both the surface plate, which is the lower assembly fixture fixing jig provided on the base, and the upper assembly fixture fixing jig, which is provided on the arm, the positioning pins are placed on two lines that are perpendicular to each other at the center of each board surface. Since the positioning pins are installed by screwing into a plurality of provided bolt holes, whenever the dimensions of the insulator metal fittings are changed, the positioning pins have to be reinstalled each time.

In addition, most bolt holes in insulator fittings are arranged on a circumference with a constant diameter determined by the standard, but sometimes bolt holes are arranged on a circumference with a diameter that is not in the standard. Insulated metal fittings may be designed.

When assembling such a product, it is necessary to newly manufacture a surface plate, which is a jig for fixing the lower assembly metal fittings, and a new jig for fixing the upper assembly metal fittings, and install them on the assembly machine.

(Means for Solving the Problems) The present invention was devised to solve the above problems, and as shown in FIG. In the assembly fixture fixing jig 4 of the assembly machine 3 of the columnar insulator device 2 cemented to the The positioning pins 7 that fit into the bolt holes 6 of the insulator fittings 1 are arranged along the fitting fixing surface 5 with at least three strips provided radially outward from the center 8 of the fitting fixing surface 5, as shown in FIG. In the illustrated example, it is essential to install a slider 10 that is slidably fitted into four cross-shaped grooves 9.

The slider 10 is provided with a plurality of screw holes 11 for installing the positioning pin 7, and the slider fixing screw 12 is installed in one of the screw holes 11 of the slider 10 to fix the slider 10. A gauge jig is used to center the mutual positions of the positioning pins 7 implanted in each slider 10, which is provided on the bottom surface of the slider 10 that is pressed by the slider 10. This is a preferred embodiment of the invention.

(Function) The assembly metal fixture fixing jig 4 of the present invention is mounted on the upper and lower surface plates 16 of the assembly machine 3 by bolts (not shown) through mounting screw holes 15 provided from the back side of the assembly metal fixture fixing jig 4. The positioning pin 7 is fixed to the slider 10 which is slidably fitted into at least three grooves 9 provided along the fitting fixing surface 5 radially outward from the center of the fitting fixing surface 5. Because the positioning pins 7 are implanted, when centering the relative positions of the positioning pins 7 using a gauge jig, or when aligning the bolt holes 6 of the insulator fitting 1 with at least two positioning pins 7, insert them into the holes of the gauge jig. Or, after fitting it into the bolt hole 6 of the insulator fitting 1, slide the slider 10 and fitting the other positioning pin 7 into the hole of the gauge jig or the bolt hole 6 of the insulator fitting 1. That can be done easily.

In this case, positioning is done at at least three points, so when aligning with a gauge jig, the bolt hole 6 of the insulator fitting 1 is aligned with the insulator fitting 1 correctly arranged with respect to the center of the insulator fitting 1. When the center of the insulator fitting 1 matches the center of the assembly.

When assembling the insulating device 2 using insulating metal fittings 1 of the same size, by fixing the slider 10 with the slider fixing screw 12, it is possible to assemble the insulating device 2 of the same size one after another.

(Effect of the invention) If an insulator device is assembled using the assembly metal fixture fixing jig of the present invention, there is no need to replace the assembly metal fixture fixing jig every time when assembling an insulator with different dimensions. , it is possible to save time during production changeovers.

In addition, the insulator metal fittings can be attached with accurate centering, and therefore an insulator device with accurate dimensions can be assembled and manufactured.

As mentioned above, this invention has many advantages,
There are some areas that make a huge contribution to the development of the industry.
