Embodiment
The utility model embodiment discloses a kind of phasing degree testing tool, with the problem that the phasing degree detection speed effectively solving camshaft is slow.
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Refer to Fig. 1-Fig. 2, the structural representation of the phasing degree testing tool that Fig. 1 provides for the utility model embodiment; Fig. 2 be phasing degree testing tool in Fig. 1 partly cut open structural representation.
In a kind of specific embodiment, present embodiments provide a kind of phasing degree testing tool, this phasing degree testing tool comprises positioning through hole, positioning key 3 and register pin 1, wherein positioning through hole is by being slidably matched the axis of positioning spindle with the main shaft of camshaft, the concrete axis determining main shaft to point offseted with locating shaft by least three on a certain xsect, this concrete positioning through hole can be positioning cylinder hole, and the aperture of this setting circle post holes is equal with the diameter of axle of main shaft.
Wherein positioning key 3 coordinates with the positioning spline of camshaft, namely coordinates to make this phasing degree testing tool cannot relative tested cam axle by positioning key 3 and the positioning spline of camshaft.The shape of this positioning key 3 should coordinate the keyway of camshaft to arrange, and specifically can adopt the assembling and positioning key 3 on camshaft, and shape and the locator meams of this concrete positioning key 3 all with reference to prior art, can not repeat them here.
Wherein register pin 1 is for being inserted in the pilot hole of sprocket wheel, the diameter of register pin 1 and the different diameters predetermined value of pilot hole, with whether can be inserted into by register pin 1 judge pilot hole and positioning spline in pilot hole angle whether in allowed band, and then determine that the phasing degree of camshaft is whether in allowed band.This concrete register pin 1 should meet the following conditions, register pin 1 should be equal with the phasing degree of camshaft with the angle of positioning key 3, the phasing degree of camshaft herein, refer to the intermediate value of this phasing degree allowed band value, the phasing degree of such as camshaft is 18 ° ± 30 ', then register pin 1 should be 18 degree with the angle of positioning key 3 herein.The concrete diameter of this register pin 1 and the different diameters predetermined value of pilot hole, this concrete predetermined value should ensure, along with the axis of pilot hole for axis circumferentially: when offseting near the side of positioning key 3 and the hole wall of pilot hole when register pin 1, the angle of this pilot hole and positioning spline is just in time the maximal value of permissible value, such as in the scope of such as upper angle, the value of measurement should be 18 ° 30 '; When register pin 1 offsets away from the side of positioning key 3 and the hole wall of pilot hole, the angle of this pilot hole and positioning spline is just in time the minimum value of permissible value, and such as, in the scope of such as upper angle, the value of measurement should be 17 ° 30 '.
In the present embodiment, equal with the phasing degree of camshaft with positioning key 3 angle by register pin 1, and the different diameters predetermined value of the diameter of register pin 1 and pilot hole, make to only have when the phasing degree of camshaft to be measured meets the demands, register pin 1 can be inserted in pilot hole.Concrete when detecting the phasing degree of camshaft, the main shaft of camshaft to be measured is inserted in positioning through hole, positioning key 3 is matched with the positioning spline of camshaft, simultaneously in sliding process, when register pin 1 can be inserted into pilot hole, then show that the angle of pilot hole and positioning spline meets the demands, namely the phasing degree of camshaft meets the demands; On the contrary, then show that the phasing degree of camshaft does not meet the demands.Phasing degree angular range is converted into pilot hole and the angular range determining keyway by the present embodiment, and then can be measured by the difference of register pin 1 with the diameter of pilot hole.So this phasing degree testing tool can detect whether the phasing degree of camshaft meets the demands fast.
Register pin 1 and positioning through hole are conveniently set, main body 2 can be provided with, positioning through hole is arranged on the body 2, and then by installing on the body 2 by register pin 1, determine the distance between register pin 1 and positioning through hole.Considering that the scope of the permissible value of different camshafts to be measured can be different, in order to enable this testing tool adapt to more camshaft, register pin 1 can be made to be inserted into the mounting hole of main body 2 along the axis of described positioning through hole.Be provided with the register pin 1 of multiple different size simultaneously, the register pin 1 of different size can be selected for different types of camshaft.So use register pin 1 and main body 2 grafting can improve the replaceability of register pin 1.Consider that being generally of register pin 1 is cylindrical, conveniently manufacture main body 2, main body 2 can be made for cylindrical hole, so also can facilitate the installation of register pin 1 and mounting hole.
Further, conveniently manufacture main body 2, positioning key 3 and main body 2 are set to integral piece, manufacturing process meeting more complicated, based on this, can make to be plugged in together between positioning key 3 and main body 2, namely can be provided with the keyway be slidably matched with keeper on the body 2.Wherein positioning key 3 can adopt the actual key used on camshaft.In order to prevent positioning key 3 from falling down, can be provided with for stoping positioning key 3 to the boss of the axis movement of positioning through hole at the sidewall of keyway, simultaneously should be corresponding on positioning key 3 lug boss is set, offset for boss.
Consider the reason of the scale error of the main shaft of camshaft, in order to make the axis of positioning through hole as much as possible near the axis of main shaft reality, can make the sidewall of positioning through hole that the axis of positioning through hole is provided with opening 5, the size of positioning through hole can be regulated by this opening 5.Also should be provided with the locking member 4 of connection opening 5 both sides opening's edge simultaneously, be regulated the size of opening 5 by locking member 4, and then regulate the size of positioning through hole further.Wherein locking member 4 can be bolt or screw.Conveniently operate and preferably make locking member be bolt.In order to the size of positioning through hole further can be changed, the distortion groove 6 of the Axis Extension along positioning through hole can be provided with at the sidewall of positioning through hole.Regulate opening 5 by the locking degree of locking member 4, the sidewall of positioning through hole can be made to be subject to distortion power, and then the notch of distortion groove 6 can be made to diminish, the diameter of positioning through hole is diminished.In order to ensure measuring accuracy, preferably make not to be provided with between positioning key 3 and register pin 1 to be out of shape groove 6, to avoid the angle value between deflection change positioning key 3 and register pin 1.
In this instructions, each embodiment adopts the mode of going forward one by one to describe, and what each embodiment stressed is the difference with other embodiments, between each embodiment identical similar portion mutually see.
To the above-mentioned explanation of the disclosed embodiments, professional and technical personnel in the field are realized or uses the utility model.To be apparent for those skilled in the art to the multiple amendment of these embodiments, General Principle as defined herein when not departing from spirit or scope of the present utility model, can realize in other embodiments.Therefore, the utility model can not be restricted to these embodiments shown in this article, but will meet the widest scope consistent with principle disclosed herein and features of novelty.
