Embodiment 1

[0059] like figure 2 As shown, the contact seat assembly and crimping tooling includes a frame, and the frame includes a bottom plate 21. Three columns 27 are arranged on the bottom plate 21, and a connecting plate 30 is provided between the upper ends of two adjacent columns 27. The three columns 27 form The triangular structure can ensure the stability of the rack. In other embodiments, only two columns may be arranged on the bottom plate.

[0060] In this embodiment, the bottom plate 21 is provided with a jack 22, the driving end of the jack 22 is provided with a lower positioning seat 36, the lower positioning seat 36 is used for positioning the static contact seat 11, and the lower positioning seat 36 is driven by the jack 22 to move upwards, that is The jack 22 drives the lower positioning seat 36 to move upward to the positioning seat; because the static contact finger 13 on the static contact seat 11 and the shielding cover 12 are perfectly assembled together, the fo...

Embodiment 2

[0082] like Figure 7 As shown, in this embodiment, the contact seat assembly crimping tool is used for crimping the moving contact seat assembly, and the moving contact seat assembly includes a moving contact seat 52 and an arc strike ring 51 . On the basis of Embodiment 1, the contact seat assembly and crimping tooling also includes an arc pilot ring positioning seat 50 and a moving contact seat positioning seat 53. The arc pilot ring positioning seat 50 is provided with a positioning protrusion and an upper step hole. The contact seat positioning seat 53 is provided with a positioning groove and a lower stepped hole. like Figure 4 and Figure 5 As shown, the groove bottom of the upper positioning groove 48 is provided with an upper threaded hole 49, the groove bottom of the lower positioning groove 45 is provided with a lower threaded hole 46, and the arc pilot ring positioning seat 50 is fixed on the groove bottom of the upper positioning groove 48 by screws. The movin...

Embodiment 3

[0084] In Embodiment 1, the bottom plate 21 of the frame is provided with a guide rod 23, and the guide rod 23 extends vertically, and the lower positioning seat 36 is provided with a guide sleeve 24, and the lower positioning seat 36 is guided by the guide rod 23 and the guide sleeve 24 Fits with guides to mount on the rack. In this embodiment, a guide rod is provided on the bottom plate of the frame, and a guide groove is provided on the guide rod, and the guide groove extends vertically. The guides are mounted on the frame.

Abstract

The invention relates to a contact seat assembling and crimping tool. The contact seat assembling and crimping tool comprises a frame; a lower positioning seat arranged on the rack, wherein the lowerpositioning seat is provided with a lower positioning groove, and the lower positioning groove is a circular groove and is used for positioning the lower end of the static contact seat; an upper positioning seat arranged on the rack and located above the lower positioning seat, wherein the upper positioning seat is provided with an upper positioning groove, and the upper positioning groove is a circular groove and used for positioning the upper end of the shielding case; and a hydraulic driving device used for driving the lower positioning seat to move towards the upper positioning seat so asto assemble the static contact seat, the static end contact finger on the static contact seat and the shielding case together in an interference manner. According to the tool in the embodiment, the static contact seat, the static end contact finger on the static contact seat and the shielding case are assembled together in an interference mode through the hydraulic driving device, compared with athermal expansion and cold contraction mode, the shielding case does not need to be heated, and the production efficiency is improved; moreover, the hydraulic oil of the hydraulic driving device can be recycled, so that the production cost for assembling the static contact seat is reduced.

Description

technical field [0001] The invention relates to a crimping tool for assembling a contact seat. Background technique [0002] LW series tank circuit breaker is a high-voltage circuit breaker product that combines the functions of circuit breaker and current transformer. , fast grounding, lightning arrester and other functions of a combination of high-voltage electrical products. The above two series of products need to use the core assembly of the arc extinguishing chamber. In order to meet the miniaturization design of this core assembly, the contact seat assembly uses a crimping structure, which can ensure the contact position. Consistent flow and reliable contact resistance. [0003] Take the static contact seat assembly as an example, such as figure 1 As shown, the assembly of the static contact seat includes a static contact seat 11, a shield cover 12 is arranged on the static contact seat 11, and a static end contact finger 13 is provided between the shield cover 12 ...
