Abstract
C type energy accumulation spring dismantling device, comprises C type piece, and C type piece one side inwall is provided with front top, and it is top that C type piece opposite side inwall is provided with screw thread, and screw thread is top is connected with handle by mandrel.C type energy accumulation spring dismantling device of the present utility model passes through rotary handle, band moving mandrel rotates, make that screw thread is top pushes ahead, with front top interaction, produce certain pressure centre head is compressed into spring body, make it extend axially certain size, by the disassemble and assemble work of energy accumulation spring become efficiently, simple, safety is safe.
Description
Technical field
The utility model relates to a kind of energy accumulation spring dismounting pincers, a kind of breaker energy storage spring folding dress specific purpose tool of using in especially applicable 10kV breaker mechanism service work.
Background technology
In the service work of 10kV breaker mechanism, energy accumulation spring disassemble and assemble work is being thorny, a dangerous but indispensable processing step, and careless slightly its spring that can cause collapses, and from individual damage equipment, workmen's personal safety is caused to serious harm.At present, on market, without its specific purpose tool, sell, producer is not equipped with its specific purpose tool yet.When the existing conventional tool of upkeep operation librarian use (as screwdriver, nipper plier etc.) is carried out its operation, labour intensity is large, success rate is low, and very easily damages energy accumulation spring.
Application number is that the energy accumulation spring that the patent of CN200620031076.1 discloses a kind of vacuum circuit breaker press-fits pincers, hinged by two arc motion arms with U-lag plug, this press-fits pincers and is mainly used in vacuum circuit breaker, be energy accumulation spring axially on afterburning, draw energy accumulation spring to Len req, this kind of afterburning mode can cause energy accumulation spring to damage by undue force.
Utility model content
The purpose of this utility model is while carrying out its operation for conventional tool in prior art, labour intensity is large, success rate is low, and very easily damage the problems such as energy accumulation spring, the C type energy accumulation spring dismantling device that a kind of disassemble and assemble work becomes efficiently, simple, safety is safe is provided.
To achieve these goals, the technical solution adopted in the utility model is: C type energy accumulation spring dismantling device, comprise C type piece, and described C type piece one side inwall is provided with front top, and it is top that C type piece opposite side inwall is provided with screw thread, and screw thread is top is connected with handle by mandrel.
Described screw thread is top has corresponding jackscrew groove with middle part mandrel.
The described front top and top diaphragm that is provided with of screw thread.
Compared with prior art, C type energy accumulation spring dismantling device of the present utility model passes through rotary handle, band moving mandrel rotates, mandrel endoporus has screw thread and screw thread is top cooperatively interacts, screw thread is top under the technical conditions of pressure and special shape, can not rotate can only before and after feeding, it is this that from helical rotation, to become the power of straight-line feed quite large, by the disassemble and assemble work of energy accumulation spring become efficiently, simple, safe safe.The utility model material mainly adopts medium carbon steel to make, and intensity is large, corrosion-resistant, physical life is long, efficient, safe, convenient.
Accompanying drawing explanation
Fig. 1 structural representation of the present utility model.
The specific embodiment
As shown in Figure 1, C type energy accumulation spring dismantling device, comprises C type piece 1, and C type piece 1 one side inwalls are provided with front top 2, and it is top 3 that C type piece 1 opposite side inwall is provided with screw thread, and screw thread top 3 is connected with handle 5 by mandrel 4.There is corresponding jackscrew groove at the middle part of screw thread top 3 and mandrel 4, toply can not too stressed in the situation that, enter rotary fine adjustment, to adapt to the spiral angle of energy accumulation spring.Before top 2 and screw thread top 3 be provided with diaphragm, can reduce the scratch to energy accumulation spring.
The utility model is by rotary handle 5, and band moving mandrel 4 rotates, and screw thread top 3 is pushed ahead, and with front top 2 interactions, produces certain pressure centre head is compressed into spring body, makes it extend axially certain size, reaches the object of its dismounting.
Mandrel 4 endoporus have screw thread and screw thread top 3 to cooperatively interact, screw thread top 3 under the technical conditions of pressure and special shape, can not rotate can only before and after feeding, this from helical rotation, to become the power of straight-line feed quite large, is enough to centre head to be pressed into.
The utility model material mainly adopts the making such as medium carbon steel, high-strength aluminum alloy, and intensity is large, corrosion-resistant, physical life is long, efficient, safe, convenient.
