Abstract
The invention discloses a crankshaft timing and positioning fixture with a rapid positioning property and belongs to the technical field of engine assembly fixtures. The fixture comprises a mounting plate, wherein the plate surface of one end of the mounting plate is provided with a positioning column matched with a central hole in the rear end of a crankshaft and a through hole which corresponds to a bolt hole in the rear end of the crankshaft; the plate surface of the other end of the mounting plate is provided with a positioning pin matched with a positioning hole positioned in a cylinder body of the rear end side of the crankshaft; the positioning pin is connected with a pin shaft which is arranged in a manner of sliding along a direction vertical to the plate surface of the mounting plate; the pin shaft is provided with a step; a spring sleeving the pin shaft is arranged between the step and the mounting plate; the step and the positioning pin are positioned on the same side of the mounting plate. The crankshaft timing and positioning fixture is capable of ensuring stable crankshaft timing position, preventing the crankshaft from rotating and further avoiding the influence to the assembly quality in a process of mounting other timing parts.
Description
Technical field
The present invention relates to technical field, locate crankshaft timing positioning tool efficiently in particular to one.
Background technology
The timing system of engine relates to the key factors such as the time of ignition of engine, when timing system is installed need bent axle, camshaft all to rotate and fix to correct timing position, by manually bent axle being fixed or adopting some interim instruments to be propped up by bent axle now mostly, when manually fixing, people's fixed crankshaft, a people installs timing system, labor intensive, efficiency is low, according to instrument, bent axle is propped up, easily rotate against bent axle loosely and in the process of installing timing system, cause engine timing mistake.
Summary of the invention
The object of the present invention is to provide a kind ofly utilize the locating hole on crankshaft rear end centre bore, bolt hole and rear end side cylinder body thereof to locate, solid and reliable location crankshaft timing positioning tool efficiently, to solve the problem.
For realizing the object of the invention, the technical scheme adopted is: one locates crankshaft timing positioning tool efficiently, comprise installing plate, the plate face of installing plate one end is provided with and the locating dowel that crankshaft rear end centre bore matches and the through hole corresponding with crankshaft rear end bolt hole; The plate face of the installing plate other end is provided with the alignment pin suitable with the locating hole be positioned on the cylinder body of crankshaft rear end side, alignment pin is connected with the bearing pin arranged along the slip of direction, at right angle setting plate plate face, bearing pin is provided with step, be provided with the spring be set on bearing pin between step and installing plate, step and alignment pin are positioned at the same side of installing plate.
Further, installing plate offers counter sink, bearing pin slides setting in the diameter holes of counter sink, and one end of spring is positioned at the hole, large footpath of counter sink, and the other end is against on step.
Further, the end of described bearing pin is provided with ball grip.
Further, described installing plate is alumiaum article.
The invention has the beneficial effects as follows, after bent axle forwards timing state to, the locating hole on crankshaft rear end centre bore, rear end cylinder body is inserted respectively by locating dowel, alignment pin, this locating hole can adopt the speed changer mould assembling locating hole of cylinder body, be screwed in crankshaft rear end bolt hole by bolt through the through hole on installing plate again behind location, thus realize fixing, alignment pin can realize more convenient location by moving around of bearing pin, ensure that the timing position that bent axle is stable, avoiding the bent axle when installing other timing parts rotate and affect assembly quality.
Accompanying drawing explanation
Fig. 1 is the sectional view of location provided by the invention crankshaft timing positioning tool efficiently;
Fig. 2 is the upward view of locating crankshaft timing positioning tool efficiently shown in Fig. 1.
Detailed description of the invention
Also by reference to the accompanying drawings the present invention is described in further detail below by specific embodiment.
Fig. 1, Fig. 2 show location provided by the invention crankshaft timing positioning tool efficiently, comprise installing plate 1, installing plate 1 can be alumiaum article, lighter, easily install, the plate face of installing plate 1 one end is provided with and the locating dowel 2 that crankshaft rear end centre bore matches and the through hole 3 corresponding with crankshaft rear end bolt hole; The plate face of installing plate 1 other end is provided with the alignment pin 4 suitable with the locating hole be positioned on the cylinder body of crankshaft rear end side; Alignment pin 4 is connected with the bearing pin 5 arranged along the slip of direction, at right angle setting plate 1 plate face, bearing pin 5 is provided with step 6, is provided with the spring 7 be set on bearing pin 5 between step 6 and installing plate 1, and step 6 and alignment pin 4 are positioned at the same side of installing plate 1.
Installing plate 1 offers counter sink, and bearing pin 5 slides setting in the diameter holes of counter sink, and one end of spring 7 is positioned at the hole, large footpath of counter sink, and the other end is against on step 6.The end of bearing pin 5 is provided with ball grip 8.
During use, bent axle is forwarded to timing state, then locating dowel 2, alignment pin 4 are inserted respectively the locating hole on crankshaft rear end centre bore, rear end cylinder body, this locating hole adopts the speed changer mould assembling locating hole of cylinder body, also other locating holes be positioned on crankshaft rear end side cylinder body (i.e. rear end of the cylinder block) can be adopted, be screwed in crankshaft rear end bolt hole by bolt through the through hole 3 on installing plate 1 again behind location, realize fixing, after timing system is installed, this frock is pulled down.
The foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, for a person skilled in the art, the present invention can have various modifications and variations.Within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
