Utility model content
The defect existing for above-mentioned prior art, the purpose of this utility model is to provide one can locate fast valve position, improves the valve fast assembly and disassembly mechanism of dismounting efficiency.
For achieving the above object, the technical solution of the utility model is: valve fast assembly and disassembly mechanism, comprise L shaped base, depression bar and be located at L shaped base supporting base on one side, wherein, also be provided with travelling arm, cylinder with piston rod, the another side of described travelling arm one end and L shaped base is slidably connected, the other end connects depression bar by connector, described depression bar can moving axially along self, pressure shaft is to relative with supporting base, the nearly supporting base of described depression bar one end is provided with pressure ring, and the piston rod of described cylinder is connected with travelling arm, and described supporting base is provided with the location structure of valve.
While adopting technique scheme, taking dismounting valve spring as example, valve disc is supported on supporting base, because supporting base is provided with the location structure of valve, so only the valve disc of valve need be positioned over to corresponding position, just can ensure that laterostigmatal spring base is coaxial with depression bar and pressure ring, the piston rod of cylinder drives travelling arm to slide, the depression bar being connected with travelling arm by connector also moves thereupon, in the time that the pressure ring on depression bar and cotter seat offset, mobile depression bar, valve spring compression, just can take out valve spring locker, when the piston rod of cylinder drives travelling arm to slide in the opposite direction, can take out valve spring.The utility model can be located valve position fast, and without the artificial position of adjusting valve, so energy fast assembling-disassembling valve spring, dismounting efficiency is high.
Further, described location structure is sucked type electromagnet, described sucked type electromagnet is provided with the positioning table that coordinates multiple size valve discs, each positioning table forms the stepped of annular, the positioning table of annular step scalariform can coordinate the valve disc of different size, and sucked type electromagnet has magnetic force, the valve that can ensure to be positioned on positioning table is stablized.
Further, described location structure comprises the positioning cylinder and the jaw being connected with its piston rod with piston rod, the piston rod of positioning cylinder drives jaw, positioning cylinder can provide larger power as power source, so the power of jaw action on valve disc is also larger, so can ensure that in process that pressure ring exerts pressure on spring base, valve is all the time in stable state.
