Abstract
The utility model discloses a novel installing and positioning clamp for a gear chamber cover of a diesel engine. A positioning sleeve which can be sleeved at the front end of a crankshaft is manufactured; a threaded bush is arranged in the positioning sleeve; and a threaded push rod is arranged on the threaded bush, so that the positioning clamp can be withdrawn after positioning and installing are completed. The novel installing and positioning clamp has the advantages of reasonable design, convenience in using and high positioning accuracy.
Description
Technical field
The utility model relates to the installation positioning fixture of diesel engine part, and specifically the Novel diesel engine gear chamber cover is installed positioning fixture.
Background technology
Existing Gear Cavity Cover of Diesel Engine when mounted, majority is the alignment pin location that relies on the gear chamber.The precision of this locate mode is to be determined by the locating hole machining accuracy of body and gear chamber.Because the cumulative limit of body and gear chamber location tends to cause center, gear chamber cover Front oil seal hole and crankshaft center misalignment of axe larger, and then causes Front oil seal leakage of oil, oil impregnate.In addition, owing to adopt the alignment pin on the gear chamber to locate, gear chamber cover selection and wall thickness are had relatively high expectations, gear chamber cover can only adopt cast aluminium and cast iron, and cost is higher.
Summary of the invention
The purpose of this utility model is that a kind of Novel diesel engine gear chamber cover of design is installed positioning fixture, improves positioning accuracy, accelerates installation rate, relaxes the requirement to the gear chamber cover material.
The utility model is to realize like this purpose of design: make 1 positioning sleeve 1 that can entangle crankshaft front end; In positioning sleeve 1, by screw 4 screw-thread bush 2 is installed; Screw putter 3 is installed on the screw-thread bush 2.During use, positioning sleeve 1 is enclosed within the front end of bent axle, relies on the front end of bent axle to locate to gear chamber cover, again with the gear chamber cover oil sealing hole by behind positioning sleeve 1 excircle orientation, tighten gear chamber cover.After gear chamber cover location, the installation, rely on screw putter 3 and screw-thread bush 2, withdraw from positioning fixture.
The utility model is easy to use, and speed is fast, and precision is high.Less demanding to the gear chamber cover material, even can adopt cost to have more the punching type gear chamber cover of advantage.
Description of drawings
Fig. 1 is the utility model structural representation.
Sequence number among the upper figure: positioning sleeve 1, screw-thread bush 2, screw putter 3, screw 4.
The specific embodiment
Below in conjunction with accompanying drawing, a non-limiting examples is illustrated.
Make 1 positioning sleeve 1 that can entangle crankshaft front end; So that positioning sleeve 1 is (0.07 ,-0.05) mm with gear chamber cover oil sealing hole locating shaft tolerance dimension; With crankshaft front end locating hole tolerance dimension be (+0.02 ,+0.04) mm.In positioning sleeve 1, by 3 M5 screws 4 screw-thread bush 2 is installed; Screw putter 3 is installed, so that in the location, when end is installed, withdraw from positioning fixture on the screw-thread bush 2.
