Abstract
The invention relates to the field of engine installation tools, in particular to a timing positioning device for a camshaft. The device comprises a T-shaped fixing frame and an F-shaped positioning frame, wherein a vertical rod of the F-shaped positioning frame and a vertical rod of the T-shaped fixing frame are connected through two bolts; two threaded holes are formed in the end of a first horizontal rod of the F-shaped positioning frame along the direction of the horizontal rod; the axes of the two threaded holes are parallel to the vertical rod of the F-shaped positioning frame; and two positioning screws pass through the threaded holes and are positioned. The camshaft is fixed by the adjustable positioning screws, so that positioning failure caused by processing errors of two planes of the camshaft can be eliminated, and the positioning effect is ensured; and the adjustable positioning screws are flexible and adjustable, so the device also can be used for installing camshafts of different specifications, and the generality of the device is improved.
Description
Technical field
The present invention relates to a kind of engine erecting tools field, specifically, relate to a kind of camshaft timing positioner.
Background technology
In engine art, assembling is during camshaft, camshaft-bearing cap with bolt after, rotate in order to prevent camshaft, need utilize frock to come the positioning cam axle, cooperate just can guarantee the correct time between camshaft timing gear and the camshaft drive system.But different camshafts, perhaps the camshaft of same model owing to mismachining tolerance, all possibly influence the locating effect of frock, and this just has higher requirement to frock.
Summary of the invention
The objective of the invention is to overcome the defective of the existence of above-mentioned prior art, a kind of camshaft timing positioner is provided.
In order to realize the object of the invention, the technical scheme that the present invention adopts is:
A kind of camshaft timing positioner; Comprise fixed mount and locating rack; Said fixed mount is " T " shape; Screwed hole is set at the middle part of the cross bar of said " T " shape fixed mount and two ends are provided with bolt hole respectively; The end of the montant of said " T " shape fixed mount is provided with screwed hole, two screwed holes on said " T " shape fixed mount and 4 axially bored lines of two bolts hole are parallel to each other and all perpendicular to the same plane of said fixed mount " T " shape, said locating rack is " F " shape; Constitute by a montant and first cross bar and second cross bar; The montant of said " F " shape locating rack and first cross bar and second cross bar are vertical respectively, and the end of the montant of said " F " shape locating rack is provided with two bolts hole, and the axially bored line that the end of the montant of said " F " shape locating rack is provided with two bolts hole is parallel to each other and is parallel with first cross bar of said " F " shape locating rack; Said locating rack is connected the montant of the montant of said " F " shape locating rack with said " T " shape fixed mount through two bolts with fixed mount; First crossbar end of said " F " shape locating rack is provided with two screwed holes along the cross bar direction, and the axis of two screwed holes is parallel with the montant of said " F " shape, and two dog screws pass said screwed hole location.
Each rod member longitudinal section of described fixed mount and locating rack is rectangle.
Beneficial effect of the present invention is: adopt fabricated structure; Improve whole assembling, adopted an adjustable screw fixed convex wheel shaft of adjusting, can eliminate the locate failure that camshaft two plane mismachining tolerances are caused; Locating effect is guaranteed; Because the whole screw in adjustable location is adjustable flexibly, this frock also can be used for the installation of different size camshaft, has improved its versatility.
