Embodiment
A kind of nozzle of circuit breaker with the embodiment of assembly tooling as shown in Fig. 1 ~ 7: comprise in use for being set in the gear frame of respective jets 6 peripheries, gear frame is a sleeve 7, sleeve has the endoporus coordinating for the periphery face of cylinder, the upper end guiding with spout, on the lower sleeve wall of sleeve around being circumferentially symmetrically arranged with two lightening grooves 7-1 that extend to sleeve lower surface, lightening grooves is for alleviating the weight of sleeve, thereby be more conducive to operating personnel to sleeve and the spout application of force, can be because of the weight of sleeve not excessive and cause the excessive problem of labor intensity of operating staff.In sleeve wall between two lightening grooves, be provided with the strengthening rib strip 7-2 that length is extended along the vertical direction, and the sleeve wall lower end between two lightening grooves is provided with respectively and on spout two corresponding left pin passage 7-3 and right pin passages of installing hole radially, left and right pin passage is downward opening end face groove structure, and the cross sectional shape of end face groove is arch door shape.The upper end of sleeve is installed with cover plate 8, and the center position of cover plate is provided with the square hole 9 for moment of torsion input, in this square hole, can insert torque spanner, and it is fastening that convenience is determined moment, thereby eliminates the dispersiveness of assembling.Sleeve coordinates with spout spline by positioning component, positioning component comprises respectively and on spout two corresponding left alignment pin 5 and right alignment pins 2 of installing hole radially, left and right alignment pin is multidiameter structure, the path section diameter of left and right alignment pin coincide adaptive with the aperture of corresponding radially installing hole, left alignment pin is installed on the first support 1, right alignment pin is installed on the second support 4, is provided with and forces left and right alignment pin to keep being plugged in the elastic holding structure in corresponding pin passage and installing hole radially between first and second support.Elastic holding structure comprises U-shaped elastic component 3, U-shaped elastic component have can relative resilient left side arm 3-1 and the right arm 3-2 of distortion and opposing strain, the first support is fixedly arranged in described right arm, and the second support is fixedly arranged on the arm of described left side, and first and second support is crisscross arranged on left and right directions.
During use, operating personnel are first to first, two supports apply relative direction active force, due to first, two supports are crisscross arranged, so now left, the opposing motion of right alignment pin meeting, first, the C shape mouth that two supports form can expand, then by first, the C shape mouth that two supports form is installed in the periphery of spout, unclamp first, two supports, under the elastic reaction of U-shaped elastic component, left, right alignment pin relative motion difference positioning and plug-in mounting is in the radially installing hole of correspondence, maintenance effect due to U-shaped elastic component, left, what right alignment pin was firm is positioned in corresponding radially installing hole, then operating personnel can by sleeve from top to bottom be sheathed on spout periphery, in sleeve moving process from top to bottom, it is peripheral that the end face groove of sleeve lower end snaps in corresponding shop bolt gradually, by the connection function of shop bolt, sleeve spline relative to spout, subsequently the moment of torsion output of torque spanner is inserted in the square hole on cover plate, by torque spanner, to sleeve, apply quantitative moment.
First and second support is crisscross arranged, can handled easily personnel to first and second support application of force; Left and right alignment pin is multidiameter structure, and the large footpath section of corresponding alignment pin coordinates with spout outer peripheral face block, thereby guarantees that each alignment pin enters the corresponding radially consistency of the installing hole degree of depth; Lightening grooves is offered in the lower end of sleeve, to alleviate the weight of sleeve, reduces operating personnel's labour intensity, and the upper end of sleeve is still loop configuration, and the endoporus of this loop configuration coordinates with the periphery face of cylinder guiding of spout, prevents that sleeve from tilting in the course of the work.
In other embodiment at this nozzle of circuit breaker with assembly tooling: first and second support can not be crisscross arranged yet, such as is oppositely arranged, now the first support is fixedly arranged on the left side arm of U-shaped elastic component, and the second support is fixedly arranged on the right arm of U-shaped elastic component; Certainly when the first support is hinged and connected, elastic holding structure can be extension spring or the top spring being arranged between first and second support; Lightening grooves can also be replaced by lightening hole, and lightening grooves can not established yet certainly; Pin passage can also be pin perforation, now when assembling, needs first gear frame is sheathed on to spout periphery, make each pin perforation with each radially installing hole corresponding after, more left and right shop bolt is threaded onto respectively to corresponding pin perforation and radially in installing hole; Left and right shop bolt can also be plain shaft structure; Gear frame can be also an annular frame structure; The square hole being arranged on cover plate can also be replaced by an outer square column, now can apply moment of torsion by outside square column and be with moving sleeve to rotate.
The embodiment of positioning component is as shown in Fig. 1 ~ 3: the concrete structure of positioning component is identical with the positioning component described in assembly tooling embodiment with above-mentioned each nozzle of circuit breaker, is not described in detail in this.
