The specific embodiment
Specify the present invention below in conjunction with specific embodiment and accompanying drawing.
Embodiment 1:
As shown in Figure 1; The assembly tooling 20 of the engine timing chain system of present embodiment is processed by plastic injection-moulded; The shape-consistent of its shape and the timing chain system that assembles; Frock 20 is provided with spacing recess in each position component of corresponding timing chain system, and frock 20 back sides are provided with the through hole of aperture greater than the construction bolt diameter in the position of the installing hole of corresponding each parts, and frock 20 is provided with the through hole that the aperture is slightly larger than axis hole in the position of corresponding each sprocket wheel axis hole.
Like Fig. 1, shown in 2, specifically:
Frock 20 is provided with the spacing recess 21 that profile is slightly larger than above-mentioned sprocket diameter in the position of the camshaft sprocket 1 of corresponding timing chain system, crankshaft sprocket 8, function sprocket wheel 5,11; The position of the hollow-out parts of corresponding camshaft sprocket 1 and function sprocket wheel 5 is provided with spacing block set 22 in the spacing recess 21, is unlikely to come off to guarantee that each sprocket wheel can be fixed on the frock 20 better.
Frock 20 is provided with the limited impression 25 that profile is slightly larger than each chain and guide rail profile at the chain 4,10 of corresponding timing chain system and the position of guide rail 3,6,7,9,12, moves to guarantee chain and each guide rail.
Frock 20 is provided with the spacing recess 23 that profile is slightly larger than stretcher 2 profiles in the position of the stretcher 2 of corresponding timing chain system; The position of corresponding stretcher 2 hollow-out parts is provided with spacing block set 24 in the spacing recess 23, is unlikely to come off to guarantee that stretcher 2 can be fixed on the frock 20 better.
Frock 20 is provided with hollow-out parts 27 at camshaft sprocket 1, crankshaft sprocket 8, the function sprocket wheel 5 corresponding to the timing chain system with the zone that chain 4 is surrounded, and to alleviate frock weight, makes things convenient for the workman to assemble.
The spacing recess of frock 20 is relevant with frock 20 materials with gap length between timing chain system each parts, and when adopting the bigger plastics of elasticity, the gap can be done smallerly; Probably within 3 millimeters, when adopting the less plastics of elasticity, the gap can be done more greatly; Probably within 3～8 millimeters, in order to avoid the parts of the timing chain system of damaging prevent the frock distortion; Cause gap smaller, be difficult to dismounting.
