Support base and the second support base are fixed on engine cylinder block both sides, and the fixture is located at the top in the middle part of camshaft and passes through spiral shell
Bolt is fixedly connected with the first support base and the second support base, and lower section is provided with the screens corresponding with camshaft in the middle part of fixture.
Further, first support base is cuboid block, and the side of the first support base is provided with two first pin-and-holes, first
The first tapped through hole is provided with the top of support base.
Further, second support base is an assembly, and the second support base includes base and Contraband type structure, Contraband type knot
Structure includes one side vertical connection of short slab, long slab and linkage section, linkage section and base, the one end of short slab and long slab away from linkage section
The second pin-and-hole is respectively equipped with, base is provided with the second tapped through hole.
Further, first support base, the second support base and fixture are irony workpiece.
Further, the steady pin passes through the first pin-and-hole and the second pin-and-hole respectively by the first support base and the second support base
It is fixed on the both sides of engine cylinder block.
Further, the screens is the rectangular frame structure of lower opening.
Relative to prior art, the disassembly and assembly structure of the present invention for camshaft of car engine can overcome existing
The deficiency of instrument, in disassembling and assembling engine camshaft, the damage of camshaft-bearing cap can be effectively reduced, has shared cam shaft
The stress of lid is held, while also limit the active force of valve spring below camshaft, it is therefore prevented that the ejection of the part of disassembly process
Drop.The present invention is simple in construction, and easy to operate, cost is cheap, significant effect.
