CN201979482U disclosed " a kind of non-return valve mounting tool ", comprises sleeve and push rod, described sleeve hollow and both ends open, can stretch into for push rod and check valve to be installed; One end of described push rod is provided with the recess for spacing one-way valve, and the other end is provided with round platform, and the diameter of described round platform is greater than the internal diameter of described sleeve.By the length of sleeve and push rod, this non-return valve mounting tool ensures that check valve is in place, and ensure that check valve can not fill partially by the axiality of sleeve and push rod and gap between the two, make check valve obtain when mounted guiding and spacing, control the installation site of check valve admirably, prevent check valve misloading, guarantee that check valve can not cause because position does not align or excessively install damaging in installation process.But, do not solve in assembling and need two people to cooperate, cause manpower to waste and easily damage the problem of a camshaft cover.
Summary of the invention
The object of this invention is to provide a kind of assembling jig for an engine camshaft cover check valve, it stably can fix a camshaft cover, and a people can complete the installation of check valve, and clamping and disassembling section easy, can efficiency of assembling be improved, avoid damage camshaft cover.
A kind of assembling jig for an engine camshaft cover check valve of the present invention, is characterized in that: a supporting base is made up of base and the pentagon side plate be connected to below on the right side of this base, is provided with a lower locating hole in the right front portion of described submounts; The bottom of one left limit plate is connected with the front portion, left side of described base, and the bottom of a right limit plate is connected with the right side of described pentagon side plate, and the lower locating hole on the bottom of an alignment pin and described base is connected.The hypotenuse of pentagon side plate front portion for supporting a camshaft cover, and bears the impulsive force of knocking check valve with alignment pin simultaneously.
Described a kind of assembling jig for an engine camshaft cover check valve, two left installing holes are provided with in the front portion of described chassis left side, be provided with in the bottom of described left limit plate two respectively with two left installing holes left bolt hole one to one, and to be connected and fixed by threaded fastener.
Described a kind of assembling jig for an engine camshaft cover check valve, described pentagon side plate is provided with three right installing holes, wherein two right installing holes are near the bottom of described pentagon side plate, two right bolts hole are provided with in the bottom of described right limit plate, described two right bolts hole respectively with two right installing hole one_to_one corresponding of pentagon side plate bottom, and to be connected and fixed by threaded fastener.
Described a kind of assembling jig for an engine camshaft cover check valve, the distance described in it between left limit plate with right limit plate is equal with the width of a camshaft cover.
The present invention carries out fixing, solid and reliable, when installing check valve by supporting seat and alignment pin to a camshaft cover multiaspect, one man operation is only needed to complete, and a clamping and dismounting camshaft cover is easy and simple to handle, thus improves efficiency of assembling, avoids damage camshaft cover.

Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is further illustrated.
See Fig. 2 to Fig. 7, shown a kind of assembling jig for an engine camshaft cover check valve, its design feature is: a supporting base is made up of base 4 and the pentagon side plate 5 be connected to below on the right side of this base, is provided with a lower locating hole 12 in the right front portion of described submounts; The bottom of one left limit plate 6 is connected with the front portion, left side of described base, and the bottom of a right limit plate 7 is connected with the right side of described pentagon side plate, and the lower locating hole on the bottom of an alignment pin 13 and described base is connected.The hypotenuse of pentagon side plate front portion for supporting a camshaft cover, and bears the impulsive force of knocking check valve with alignment pin simultaneously.
Further, be provided with two left installing holes 10 in the front portion of described chassis left side, be provided with in the bottom of described left limit plate 6 two respectively with two left installing holes left bolt hole 8 one to one, and to be connected and fixed by threaded fastener.
Further, described pentagon side plate 5 is provided with three right installing holes 11, wherein two right installing holes are near the bottom of described pentagon side plate, two right bolts hole 9 are provided with in the bottom of described right limit plate 7, described two right bolts hole respectively with two right installing hole one_to_one corresponding of pentagon side plate bottom, and to be connected and fixed by threaded fastener.
Further, described left limit plate 6 is equal with the width of a camshaft cover 3 with the distance between right limit plate 7.
Each component of this assembling jig just makes by S45C alloy: on left limit plate little inclined-plane and fixing after camshaft cover machine to add face concordant; Locating hole diameter on alignment pin upper diameter and a camshaft cover is matched in clearance.
When installing check valve, described base 4 is fixedly connected on a workbench by threaded fastener.A camshaft cover 3 is placed on this fixture, and the upper locating hole on a camshaft cover 3 is coordinated with the top of the alignment pin 13 be connected on base 4, it is spacing that described base 4, pentagon side plate 5, left limit plate 6 and right limit plate 7 carry out multiaspect to a camshaft cover respectively, fits completely in the hypotenuse of pentagon side plate 5 front portion and the back of a camshaft cover.So, camshaft cover, except direction straight up, is all limited mobile.Then, check valve 2 is put into the via hole of a camshaft cover, then by the top of jacket casing at check valve, hit with a hammer sleeve head, check valve can be seated.After having assembled, take out a camshaft cover straight up.Use this fixture only to need a people can carry out the installation of check valve, not only convenient and swift, efficiency of assembling is high, and can also avoid damage camshaft cover.
