Abstract
The utility model discloses a spring assembling tool, comprising an operating handle, a force application pallet disposed on an end of the operating handle and used to insert into two adjacent spring coils to jam a spring, and a support bar hinged on the operating handle. A hinge joint central axis of a hinge joint position of the support bar and the operating handle is in parallel or intersected with a plane in which the force application pallet is disposed. The support bar is provided with a positioning portion which is used to cooperate with an external support spacing piece to provide a supporting point for the support bar when the spring assembling tool is used. By using a level principle, the operating handle is operated by manpower, and the spring assembling tool is rotated around a hinge joint of the operating handle and the support bar so that a switching-on spring is stretched. The spring is installed or dismounted after the switching-on spring is stretched. The assembling tool is light and practical, making assembly and disassembly of the switching-on spring on a high voltage circuit breaker convenient, fast, and efficient. The assembling tool not only reduces worker labour intensity, but also improves assembling efficiency of breaker switching-on springs.
Description
Technical field
The utility model relates to a kind of assembling jig for spring.
Background technology
The normal larger spring of coefficient of elasticity that adopts is as the combined floodgate spring on high-voltage switch gear such as circuit breaker, this combined floodgate spring is larger because of himself physical dimension, and coefficient of elasticity is larger, need larger installation strength just can finish the installation and removal of combined floodgate spring, like this, dismounting combined floodgate spring is just relatively more difficult so manually, and combined floodgate spring efficiency of assembling is low.
The utility model content
The purpose of this utility model is to provide a kind of assembling jig for spring, to solve the technical problem of combined floodgate spring assembling difficulty in the prior art.
For achieving the above object, assembling jig for spring provided by the utility model adopts following technical scheme: a kind of assembling jig for spring, comprise operating grip, one end of this operating grip has the application of force clamp that blocks spring between adjacent two spring coils of spring for inserting, be hinged with support bar at operating grip, the plane parallel at the hinged central axis of this support bar and operating grip hinged place and application of force clamp place or crossing has when use for cooperating to provide support location division a little to support bar with extraneous supporting positioning member location on the described support bar.
The fork-shaped that inserts between adjacent two spring coils of spring when an end that deviates from operating grip of described application of force clamp is use clamps end, this fork-shaped clamps to have on the end and clamps groove and be positioned at two yokes that clamp the groove both sides, at least one end in the described two ends that clamp groove is flaring structure, clamps to have the lead-in chamfered that described two yokes of guiding block spring on the flaring structure on the groove.
The described groove that clamps is U-shaped groove structure.
The positioning step of the location division of described support bar for being provided with away from an end of operating grip at support bar.
On the described support bar by being installed in the articulated stand on the application of force clamp and being installed on jointed shaft hinge mounted on the articulated stand on described operating grip.
The beneficial effects of the utility model are: assembling jig for spring provided by the utility model in use, at first application of force clamp is inserted between adjacent two spring coils of combined floodgate spring, application of force clamp clamps in the gap between adjacent two spring coils that are fixed on the combined floodgate spring, then the location division on the support bar is cooperated to provide the application of force strong point to whole assembly tooling with compression set position, extraneous supporting positioning member top, last rotating operation handle, utilize lever principle, thereby the manual drive operating grip rotates the stretching of combined floodgate spring around the pin joint of operating grip and support bar, carries out corresponding installation and removal after the combined floodgate spring is stretched again.The light practicality of assembly tooling provided by the utility model makes the easy accessibility, quick, efficient of the combined floodgate spring on the primary cut-out, has both reduced labor strength, has improved again the efficiency of assembling of breaker closing spring.
Description of drawings
Fig. 1 is the structural representation of a kind of embodiment of assembling jig for spring provided by the utility model;
Fig. 2 is the use status architecture sketch when using assembly tooling dismounting spring shown in Figure 1.
Embodiment
As shown in Figure 1, a kind of embodiment of assembling jig for spring, assembly tooling among this embodiment comprises operating grip 2, this operating grip 2 is shaft-like, end at operating grip 2 is installed with the application of force clamp 21 that blocks spring between adjacent two spring coils of spring for inserting, the fork-shaped that inserts between adjacent two spring coils of spring when an end that deviates from operating grip of this application of force clamp 21 is use clamps end, this fork-shaped clamps to hold to have and clamps groove 22 and be positioned at two yokes 23 that clamp the groove both sides, the end towards support bar that clamps in the two ends of groove is flaring structure, clamp and have described two yokes of guiding on the flaring structure on the groove 22 and block the lead-in chamfered of spring, the groove 22 that clamps in the present embodiment is U-shaped groove structure.Be hinged with support bar 1 at operating grip 2, articulated stand 3 by being installed in application of force clamp on the support bar 1 and be installed on jointed shaft 4 hinge mounted on the articulated stand on described operating grip 2, the plane parallel at the central axis of this jointed shaft 4 and application of force clamp 21 places, have on the support bar 1 and be used for when using cooperating to provide support location division 11 a little to support bar with extraneous supporting positioning member location, the location division of support bar is the positioning step that is provided with away from an end of operating grip at support bar.
As shown in Figure 2, the assembling jig for spring that above-described embodiment provides in use, at first the fork-shaped with application of force clamp 21 clamps between adjacent two spring coils of end insertion combined floodgate spring 5, fork-shaped clamps being stuck on the combined floodgate spring 5 of two yokes, 23 correspondences of end, then the positioning step on the support bar 1 is cooperated to provide the application of force strong point to whole assembly tooling with the compression set position, top, upper end of the supporting and mounting bracket 6 of circuit breaker frame, last rotating operation handle 2, utilize lever principle, thereby manual drive operating grip 2 rotates 5 stretchings of combined floodgate spring around the pin joint of operating grip 2 with support bar 1, carries out corresponding installation and removal after the combined floodgate spring is stretched again.
In the present embodiment, clamping groove is U-shaped groove structure, in other embodiments, also can adopt other groove structure such as V-type or arcuate structure.
In the present embodiment, the location division on the support bar is positioning step, and in other embodiments, the location division also can adopt other structure as being opened in the structures such as detent on the support bar.
In the present embodiment, the plane parallel at the central axis of this jointed shaft and application of force clamp place, in other embodiments, the central axis of jointed shaft also can with the Plane intersects at application of force clamp place.
