Abstract
Yoke plate is strengthened to nested type. The utility model relates to a power line connects the gold utensil of usefulness, especially relates to a strenghthened type yoke plate. Need not rivet and weld. Including triangle -shaped steel sheet and steel bushing, the steel bushing nestification is in the triangle -shaped steel sheet. The triangle -shaped steel sheet adopts nested contact with the steel bushing, has avoided adopting the weldment work volume of welded mode existence big among the prior art, and the welding seam returns acid, yoke plate strength reduction scheduling problem, adopt nested contact equally also to avoid base plate strength reduction and the insecure problem of riveting that the riveting brought. Adopt the nested back of expend with heat and contract with cold principle, triangle -shaped steel sheet and steel bushing form interference fit, and the intensity of having strengthened the yoke plate makes the yoke plate more durable. Adopt nested contact, the processing method is simple more swift, practices thrift the cost, and processingquality controls more easily.
Description
Technical field
The utility model relates to the gold utensil that a kind of power circuit connects, and particularly relates to a kind of reinforced yoke plate.
Background technique
In the plate product of electric armour clamp processing, for ensureing that the intensity of plate product can meet the demands, all yoke plates that will strengthen are mostly the technique adopting welding strengthening sleeve.Its shortcoming is, the welding job amount of product is large; Quality problems caused by Welding Problems are many, and the problem returning acid after weld seam is zinc-plated is still many, causes yoke plate intensity and reduces.
State Intellectual Property Office 2014-4-15 discloses a utility model patent (patent name: the reinforced yoke plate patent No.: 201310455490X), discloses a kind of reinforced yoke plate.Be made up of substrate and the stiffening plate be set on substrate, stiffening plate is riveted on substrate, avoids the problem because welding the yoke plate intensity reduction caused.But the defect of this kind of reinforced yoke plate is, reinforced yoke plate riveting portion rivet easily comes off, and causes yoke plate to damage; Riveted joint needs to punch on substrate, reduces the intensity that substrate strength also just reduces yoke plate entirety.
Model utility content
The utility model, for above problem, provides a kind of nested of riveting and welding that do not need and strengthens yoke plate and processing method thereof.
The technical solution of the utility model is:
Comprise triangular steel plate and steel bushing, described steel bushing is nested in triangular steel plate.
Arc round angle is made in the termination one of described triangular steel plate, termination two and termination three; Described termination one has steel bushing mounting hole; Termination two and termination three place respectively have stressed side mounting hole.
Described steel bushing becomes circular; In the middle of described steel bushing cylindrical, high both sides are low, and intermediate portion has the width groove identical with triangle steel plate thickness; Described groove is circular on steel bushing cylindrical; Described groove side aspect ratio opposite side height is high, makes the boss that groove both sides height of formation is different; The side that described boss height is lower is built-in end boss, and opposite side is for stoping end boss.
The utility model intermediate cam shape steel plate and steel bushing adopt nested encryptions, avoid in prior art the welding job amount adopting the mode of welding to exist large, the problems such as weld seam returns acid, the reduction of yoke plate intensity; Substrate strength that riveted joint brings reduces and rivets unstable problem to adopt nested encryptions to it also avoid equally.After adopting principle of expanding with heat and contracting with cold nested, triangular steel plate and steel bushing form interference fit, and the intensity strengthening yoke plate makes yoke plate more durable.Adopt nested encryptions, processing method is simple and fast more, cost-saving, and quality of processing more easily controls.

Fig. 1 is structural representation of the present utility model,
Fig. 2 is the sectional view of the left view of Fig. 1,
Fig. 3 is the structural representation of triangular steel plate,
Fig. 4 is the structural representation of steel bushing,
Fig. 5 is part A enlarged diagram in Fig. 4;
In figure, 1 is triangular steel plate, and 2 is steel bushings, and 101 is steel bushing mounting holes, and 102 is stressed side mounting holes, and 103 are terminations one, 104 are terminations two, 105 are terminations three, 201 is grooves, and 202 is endoporus, and 203 is stop end boss, and 204 is built-in end boss.
Embodiment
The utility model as Figure 1-5, comprises triangular steel plate 1 and steel bushing 2, and described steel bushing 2 is nested in triangular steel plate 1.
Arc round angle is made in the termination 1 of triangular steel plate 1, termination 2 104 and termination 3 105; Described termination 1 has steel bushing mounting hole 101; Termination 2 104 and termination 3 105 place respectively have stressed side mounting hole 102.
Steel bushing 2 one-tenth is circular; In the middle of cylindrical, high both sides are low.Steel bushing 2 cylindrical intermediate portion has the width groove 201 identical with triangular steel plate 1 thickness.Groove 201 is circular on the cylindrical of steel bushing 2.Groove 201 side aspect ratio opposite side height is high, and make the boss that groove both sides height of formation is different, the side that boss height is lower is built-in end boss 204, and opposite side is for stoping end boss 203.
Processing method is as described below: select different board making triangular steel plate 1 and steel bushing 2 according to load.High temperature triangular steel plate 1 being put into 200 DEG C makes its expanded by heating, and the low temperature that steel bushing 2 puts into subzero 20 DEG C makes it be subject to cold events.Steel bushing 2 after shrinking is embedded in the middle of the triangular steel plate after expansion 1, makes yoke plate; During embedding, built-in end boss 204 first contacts with the steel bushing mounting hole 101 in triangular steel plate 1, and built-in end boss 204 is through steel bushing mounting hole 101, and triangular steel plate 1 is embedded in groove 201, stops end boss 203 to stop triangular steel plate 1 to be slided on steel bushing 2.
Ready-made yoke plate is reverted to room temperature, and steel bushing 2 is expanded, and triangular steel plate 1 is shunk, triangular steel plate shape 1 and steel bushing 2 one-tenth interference fit, forms an entirety, finally makes yoke plate finished product.Triangular steel plate and steel bushing adopt nested encryptions, avoid in prior art the welding job amount adopting the mode of welding to exist large, the problems such as weld seam returns acid, the reduction of yoke plate intensity; Substrate strength that riveted joint brings reduces and rivets unstable problem to adopt nested encryptions to it also avoid equally.After adopting principle of expanding with heat and contracting with cold nested, triangular steel plate and steel bushing form interference fit, and the intensity strengthening yoke plate makes yoke plate more durable.Adopt nested encryptions, processing method is simple and fast more, cost-saving, and quality of processing more easily controls.
