Problems solved by technology

Some compression springs with smaller diameters and shorter lengths are also assembled by manual hand pressing in vise, which is inconvenient and unsafe; for some compression springs with slightly larger diameters and longer lengths, manual assembly is not only It is inconvenient, and it is easy to cause the spring to pop out and hurt people, which is time-consuming and labor-intensive; especially for some structures with a large pre-pressure value and special end connections, it is impossible to assemble and ensure the relative position

Embodiment 1

[0024] The structure of this embodiment is as figure 2 As shown, the surface of the base 1 is provided with a spacer 7 for fixing the lower end of the spring, and the spacer 7 is provided with a mounting hole matching the structure of the spring end, and one end of the base 1 is fixed with a vertical column 2; There is a support 10 for fixing the spring-guided compression device, the spring-guided compression device includes a pin shaft 4 pierced in the support 10, the bottom of the pin shaft 4 is connected to the sliding block 3, the sliding block 3 is U-shaped, and the opening is outward, The back is attached to the column 2, the top is connected to the pin shaft 4, and the bottom has a connection with the upper end of the spring. The connection and the mounting hole are perpendicular to each other. The mounting hole is a countersunk hole 9 that matches the outer diameter of the spring. One end of the spring and the internal shaft pin is placed in the countersunk hole 9 of ...

Embodiment 2

[0026] Such as image 3 As shown, the structure of this embodiment is roughly the same as that of Embodiment 1, the difference is that: the installation hole is a rectangular hole 13 matched with the spring hanging plate, and a corresponding rectangular hole is provided at the connection. The spring is longer and the spring hanging plate is a rectangular structure 12. For the convenience of fixing the lower end of the spring, a rectangular hole corresponding to the size of the spring hanging plate is opened on the spacer to achieve the purpose of fixing one end of the spring; The end face of the corresponding rectangular hole of the plate presses the spring, and the spring is driven to realize pre-compression when the pin shaft 4 and the U-shaped sliding block 3 move up and down.

Embodiment 3

[0028] Such as Figure 4 As shown, the structure of this embodiment is roughly the same as that of Embodiment 1, the difference being that the spacer 7 is a cuboid, and a cylindrical hole is opened on the side of the spacer, and a small pin 14 for fixing the lower end of the spring is provided in the hole, so as to achieve The purpose of fixing one end of the spring.

[0029] When the above embodiment is in use, put the compression spring installed at one end into the mounting hole of the spacer in the first functional area, place the parts to be installed and align them with the sliding block of the guiding compression device in the second functional area, wait for the upper and lower After alignment, rotate the operating handle of the third functional area to make the pin shaft of the second functional area drive the sliding block to move downward, so that the spring is compressed, and when it is rotated to the maximum stroke, it is fixed. At this time, the other end of the ...

Abstract

The invention relates to a mounting apparatus for a spring, in particular to a pre-pressing apparatus for a compression spring of a disconnecting switch and an earthing switch, and belongs to the technical field of machinery. The pre-pressing assembling apparatus comprises a first functional region including a fixed base, a second functional region including a spring guide compression apparatus and a third functional region including an eccentric apparatus from the bottom up in sequence; a cushion block for fixing one end of the spring is arranged on the surface of the base; a stand column, perpendicular to the base, is fixed at one end of the base; the stand column is provided with a supporting part for fixing the spring guide compression apparatus; the spring guide compression apparatus comprises a pin shaft penetrating through the supporting part; the bottom of the pin shaft is connected with a sliding block; the eccentric apparatus comprises an eccentric wheel that is connected with the top end of the stand column through a rotating pin; and one end of the rotating pin is connected with a handle. The assembling apparatus has the advantages of high assembling efficiency, low labor intensity of workers and high reliability, so that the assembling apparatus is particularly suitable for the mass operation, and the production efficiency is greatly improved.

Description

technical field [0001] The invention relates to a spring installation device, in particular to a compression spring end pre-press assembly device for isolation and grounding switches, which belongs to the field of mechanical technology. Background technique [0002] As the most important and most used equipment in the power system, the medium and high voltage isolation and grounding switches must have extremely high reliability. The mechanism opening and closing springs and finger springs must have reliable contact pressure, and this structure It is one of the most important structures of medium and high voltage isolation and grounding switches. Because the assembly accuracy directly affects the function realization of the product, the assembly reliability and efficiency of the solid compression spring are particularly important. [0003] At present, most manufacturers use manual assembly when installing. Since medium and high voltage isolation and grounding switch mechani...
