In the figure, the device comprises a cylinder 1, a cylinder 2, an air pipe 3, a control switch 4, a base 5, a buffering elastic cushion 6, a steel cap 7, a cylindrical porcelain insulator 8, a column 9, a top template 10, a pressing plate 11, a limiting plate 12, a lower core head 13, a cantilever rod 14, a supporting rod 15, an upper core head 16, a working plate 17, an adhesive filling layer 18 and a cross-shaped slotted hole.

Detailed Description

In the figure, the cylindrical porcelain insulator steel cap filling and filling device comprises a top template 9 and a working plate 16 which are movably fixed on four upright posts 8 at intervals from top to bottom, wherein a cylinder 1 is fixedly arranged on the top template, the cylinder is connected with an air source (an air compressor) through an air pipe 2 and a control switch 3, the lower end of a piston rod of the cylinder penetrates through the top template and is movably connected with a pressing plate 10, a steel base 4 which is coaxial with the piston rod is movably arranged on the working plate, a cavity capable of accommodating a steel cap 6 is arranged on the base, a buffering elastic pad 5 is arranged in the cavity and is made of compressible elastic wear-resistant materials such as rubber and the like, the shape of the upper surface of the buffering elastic pad corresponds to the shape of the outward-bent surface of the lower end of the steel cap, the buffering elastic pad can also be formed by four springs which are arranged on the same horizontal plane at intervals (, the working plate is provided with a supporting rod 14, the upper end of the supporting rod is connected with a horizontal cantilever rod 13 through threads and a nut, the lower end of the supporting rod penetrates through a cross-shaped slotted hole 18 and is fixed through the nut (the position of the adjustable supporting rod on the working plate), one end of the cantilever rod is matched with a limiting plate 11 through threads or movably connected through a bolt (a limiting plate can be quickly changed), the cross section of the limiting plate is in a shape of an arc (tile shape), the shape of the arc corresponds to that of a cylindrical porcelain insulator umbrella skirt, and the inner curved surfaces of the limiting plate are close to cylindrical porcelain insulators 7 through different adjustable cantilever.
