Abstract
The utility model relates to an error protection tool for bevel wheel assembly, which belongs to the field of assembly tools. The utility model has the technical scheme that a circular cylinder is provided with a circle centre hole, the circumference of the circular cylinder is provided with a left-hand or right-hand groove which is provided with a helical angle, and the circular cylinder is provided with markers which can be used for discriminating the left-hand rotation and the right-hand rotation of the bevel wheel. When a bevel wheel of a camshaft is installed, the utility model can prevent the misplacement of the rotation direction of the bevel wheel, and the utility model has the advantages that the disability rate of the products can be reduced during the installation procedure, the production cost can be lowered, the work efficiency can be enhanced and the assembly performance is good.
Description
Technical field
The utility model relates to a kind of assembly tool, is specifically related to a kind of wrong instrument of helical gear rotation direction dress that prevents when assembling the engine cam helical gear.
Background technology
Engine is the power source of motor vehicle, and gear has important function very as the part of engine-driven gearing, and therefore at engine cam helical gear assembling being installed is link important in the engine production process.At the motor car engine camshaft helical gear is installed at present, the method that employing press-fits is assembled, be and avoid helical gear directly to contact and damage helical gear with external force, usually adopting metal washer to be placed on is mounted on the helical gear, forcing press or other external force act on external force on the metal gasket as directly hitting with a hammer etc., and helical gear is press-fited.And the helical gear of motor car engine camshaft, according to its type difference, helical gear kind difference, the i.e. size of gear, rotation direction difference.Difference is very little in appearance owing to left and right rotation direction helical gear, adopts the method assembling helical gear that press-fits, and Chang Yin is difficult to judge the helical gear rotation direction and produces setup error.When setup error takes place when, take out refitting if will press-fit good helical gear, in the process of taking out, helical gear surface or inner hole surface can be pulled, make product rejection.Height, inefficiency that therefore production cost is arranged, the shortcoming of assembly performance difference.
Summary of the invention
The purpose of this utility model provides a kind of wrong instrument of helical gear dress that prevents.It can prevent that helical gear rotation direction dress is wrong, and the product rejection rate that reduces in the installation process, the advantage that reduce production costs, increase work efficiency, assembly performance is good are arranged when the camshaft helical gear is installed.
The technical solution of the utility model is:
This instrument is a cylinder that is provided with circle center hole, the circumference of described cylinder be provided with the band helical angle to left-handed or cextrorotory groove, do on the cylinder can distinguish helical gear left-handed to or dextrorotation to mark.
The circle center hole diameter of described cylinder is greater than the diameter of helical gear circle center hole.
The circle center hole diameter of the utility model instrument cylinder is greater than the diameter of helical gear circle center hole, therefore revolves or cextrorotory groove in peace, do on the cylinder can distinguish helical gear left-handed to or dextrorotation to mark.
The circle center hole diameter of described cylinder is greater than the diameter of helical gear circle center hole.
Therefore the circle center hole diameter of the utility model instrument cylinder is enclosed within on the camshaft in installation helical teeth bye greater than the diameter of helical gear circle center hole, plays a supportive role when the camshaft helical gear is installed, and makes when helical gear is installed and avoids sustaining damage.This instrument on cylinder, make the band helical angle to left-handed or cextrorotory groove, coat different colors on the tooth of gear and distinguish left and right rotation direction, to avoid setup error, reduce and reduce camshaft and helical gear scrappage in the installation process, reduce production costs the advantage that the utility model is increased work efficiency in addition, assembly performance is good.
Below by embodiment the utility model is described further.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is for adopting a kind of embodiment of the present utility model.
The specific embodiment
Referring to Fig. 1.Prevent that the wrong instrument of helical gear dress from being a cylinder that is provided with circle center hole, the circumference of cylinder be provided with the band helical angle to left-handed or cextrorotory groove 1, form tooth on circumference, circle center hole 2 diameters of cylinder take out conveniently to have press-fited the back greater than the diameter of helical gear circle center hole.Do on the cylinder can distinguish left-handed to or dextrorotation to mark 5, as according to the utility model instrument left-handed to or dextrorotation to difference, on tooth, coat different colors and distinguish left and right rotation direction, so that difference, or, distinguish left and right rotation direction with other different mark such as literal, symbol, figure etc.
Referring to Fig. 2, when mounted, if when needing assembling dextrorotation helical gear 3, according to the color of the tooth on the mistake proofing instrument select dextrorotation to the wrong instrument 1 of helical gear dress that prevents, with the dextrorotation of needs assembling to the gear instrument 1 wrong with preventing the helical gear dress relatively, two helical gear rotation directions are correct when identical, when rotation direction is opposite, mistake then, the helical gear that the starting pressure machine will need to assemble is fitted on the camshaft 4, is about to helical gear and installs; In the time will assembling left-hand helical gear, according to the color of the tooth of mistake proofing instrument select left-handed to the wrong instrument 1 of helical gear dress that prevents, with needs assemblings left-handed to the gear instrument 1 wrong with preventing the helical gear dress relatively, be all correct during two helical gear rotation directions mutually, when rotation direction is opposite, mistake then, the helical gear that the starting pressure machine will need to assemble is fitted on the camshaft 4, is about to helical gear and installs.
When the mark 5 of the utility model instrument is literal, can on the instrument of left and right rotation direction, mark different words distinguishing left and right rotation direction, as left-handed to instrument on mark printed words such as " left sides ", with represent left-handed to the utility model instrument.If when needing assembling left-hand helical gear 3, selects left-handed to the wrong instrument 1 of helical gear dress that prevents, with the dextrorotation of needs assembling to the gear instrument 1 wrong with preventing the helical gear dress compare, two helical gear rotation directions are correct when identical, when rotation direction was opposite, mistake was then installed according to the method described above and is got final product.Dextrorotation in like manner to the installation method of gear with left-handed to identical.
When mark symbolization or figure, its installation method as hereinbefore.
The camshaft helical gear that adopts this method to install meets manufacturing technique requirent, reduces the scrappage of product, and the production efficiency height.
Claims (2)
1. instrument that prevents that helical gear dress is wrong, a cylinder that is provided with circle center hole is characterized in that: the circumference of described cylinder be provided with the band helical angle to left-handed or cextrorotory groove, do on the cylinder can distinguish helical gear left-handed to or dextrorotation to mark.
2. the wrong instrument of helical gear dress that prevents according to claim 1, it is characterized in that: the circle center hole diameter of described cylinder is greater than the diameter of helical gear circle center hole.
