Description
Technical field
The utility model belongs to turbo-charger technical field, relates to a kind of turbosupercharger governor lever geometric properties and corresponding assembly fixture, specifically turbosupercharger governor lever.
Background technique
Regulator is the important composition parts controlling bypass valve valve opening in turbosupercharger.Bypass valve valve opening can cause unnecessary loss in efficiency too early, and opens not reach evening and effectively reduce secondary speed and prevent overheated requirement.Therefore, need accurately to set VOP in regulator installation process.
Existing regulator can be divided into foot piece fixed and position-adjustable type by different foot piece design.Wherein adjustable foot piece design can meet higher assembly precision and coordinate surplus, but also has deficiency.Adjustable foot piece uses nut to fix foot piece position, and in existing assembly process, assembly crewman uses Handheld clamp to fix foot piece, simultaneously with spanner by nut screwing clamping on governor lever.In this process, because regulator shaft fails to fix, the risk of governor lever transfer can be brought when the nut 34 is tightened.Once transfer occurs, the regulator epithelium be connected with shaft circles round under the effect of selfer power, causes following consequence: one, cause spring for governor pretightening force to change so that the variation of bypass valve cracking pressure; Two, regulator foot piece produces augular offset because of convolution thus causes regulator and turbocharger housing joint clamping stagnation, then causes assembling to be done over again when clamping stagnation is serious.
In sum, as governor lever transfer risk will be prevented while the adjustable foot piece advantage of reservation, need to solve the problem that existing assembly process can only fix foot piece.In order to fix foot piece and shaft simultaneously, prevent relatively rotating between the two, required change comprises two aspects: one, change the design of shaft geometric properties, to meet fixed clamp demand; Two, existing fixture only fixes foot piece, needs exploitation to fix the new fixture of foot piece and shaft simultaneously.Following model utility content will provide a kind of feasible scheme of optimization.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, there is provided a kind of structure simple, ingenious, rational turbosupercharger governor lever, this governor lever effectively can solve the transfer problem of governor lever in adjustable foot piece fixation procedure, improves the one-time success rate of assembling.
Technological scheme according to the utility model provides: a kind of turbosupercharger governor lever, it is characterized in that: comprise the regulator body of rod, the described regulator body of rod is provided with rotation prevention structure portion and screw section, foot piece is threadedly connected on screw section, first fixture is nested on the empennage of foot piece, the bare terminal end of the second fixture is held on knurling structure, and the connecting rod of the first fixture is arranged in the attachment hole of the second fixture.
As further improvement of the utility model, described rotation prevention structure portion circumferential surface is provided with knurling structure.
As further improvement of the utility model, described knurling structure is uniform is arranged at regulator body of rod circumferential surface.
As further improvement of the utility model, between described knurling structure and screw section, form smooth round platform.
As further improvement of the utility model, described second fixture comprises two handles be hinged, and attachment hole is arranged at the hinged place of two handles, and the jaw of handle front end forms bare terminal end, and described jaw is snapped on knurling structure.
As further improvement of the utility model, described connecting rod is rectangular shaft, and attachment hole is rectangular opening.
Compared with prior art, advantage is the utility model: the utility model product, while the advantage retaining existing adjustable foot piece, effectively solves foot piece with the transfer problem of governor lever in nut fixation procedure; By coordinating of shaft annular knurl and assembly fixture, secured adjusted device foot piece and shaft, prevent from relatively rotating simultaneously, thus reduce and arrange pressure surge, improves subsequent handling passing rate; 360 degree of annular knurls, not modulated device angle limits; Annular knurl position is fixed, and is convenient to processing, and cost increases few; Fixture height is adjustable, highly versatile.
