Specific embodiment
Below against attached drawing, by the description of the embodiment, making to the specific embodiment of the present invention further details of
Explanation, it is therefore an objective to those skilled in the art be helped to have more complete, accurate and deep reason to design of the invention, technical solution
Solution, and contribute to its implementation.
As shown in Figures 1 to 12, present invention relates particularly to a kind of assembly tooling of camshaft phase adjuster, camshaft phases
Position adjuster includes location structure and mounting structure, which includes the front shroud one set on camshaft phase adjuster 6
The fixed plate 1 of side places assembler for positioning device that fixed plate 1 and location structure are carried out to Matching installation and for being oriented to
Tool and the limiting plate 2 for deviating from front shroud side set on fixed plate 1, assembly tool sequentially pass through limiting plate 2, fixed plate 1 and will fasten
Part carries out fastening installation with mounting structure.
Wherein, location structure is location hole, and positioning device includes positioning pin 3, and fixed plate 1 includes corresponding with location hole solid
Determine hole 7, location hole is inserted at the both ends of positioning pin 3 respectively and mounting hole 7 is fixed on the positioning.As shown in figure 3, the work(of positioning pin 3
Energy region is one section of straight pin, and the diameter of positioning pin 3 depends on location hole with matching in camshaft phase adjuster
Diameter.Positioning device preferably further includes the reinforcing rib 4 on positioning pin.The setting of reinforcing rib 4 is because camshaft phase is adjusted
Torque of the fastening bolt of device 6 when tightening is larger, which obtains that stress is also larger, and the assembly tooling in order to prevent makes
Situation about being broken with occurring positioning pin 3 in the process needs pin to have enough intensity that can just fix phase regulator without damaging
It is bad.The shape of reinforcing rib 4 is primarily limited to the shape of camshaft phase adjuster, specifically as shown in Figure 4, reinforcing rib 4 be with it is convex
The platy structure that the front shroud avris shape of wheel shaft phase regulator 6 matches.The material selection of positioning pin uses 40Cr, later
It is quenched, Surface hardening treatment.
The main function of fixed plate 1 is to provide support for positioning pin 3, and camshaft is directly against towards the side of positioning pin 3
On the front shroud of phase regulator 6.The position of two mounting holes depends on camshaft phase adjuster upper Positioning holes in fixed plate 1
Position.And the shape of fixed plate 1 will take into account intensity requirement on the basis of function is met, while reduce the use of material to the greatest extent,
Mitigate the overall weight of tooling, shape can be class ellipse, and two long arc shape sides of class ellipse are rough knot
Structure, such structure can be good at adapting to the installation assembling of camshaft phase adjuster, and materials'use is few and stability is preferable.Tool
Shown in body as Fig. 5 and Fig. 6.The material of fixed plate 1 is 45# steel, is equally quenched, Surface hardening treatment.
Assembly tool is pneumatic impact spanner, and as shown in Figure 7 and Figure 8, limiting plate 2 is equipped with to coordinate limiting assembling pneumatic impact spanner
The cavernous structure 8 of the boss of tooling.It is inserted into for the ease of the guiding of boss, guide mounting structure 9 is equipped in cavernous structure 8.It leads
Can be shape as shown in Figure 7 to mounting structure；It can be guide chute or guide plate in cavernous structure.Poroid knot
Structure 8 is multiple, and multiple cavernous structures 8.The setting of the cavernous structure 8 of multiple circumferential avris for being distributed in limiting plate 2, can make
Pneumatic impact spanner forms preferable conflict fixed effect in assembling process, avoids the occurrence of assembly tooling rotation.Specifically, it limits
2 main function of plate is the position for limiting pneumatic impact spanner, and cavernous structure 8 can be six, six irregular holes on limiting plate 2
Shape structure 8 is mainly to coordinate six boss of the tooling on pneumatic impact spanner and design, the six of the tooling of pneumatic impact spanner during use
A boss needs to pass through among six cavernous structures of limiting plate 2.The material of limiting plate is 45# steel.
In addition, the assembly tooling is further included is used to support the convex of pneumatic impact spanner tooling between fixed plate 1 and limiting plate 2
The cushion block 5 of platform.The effect of cushion block 5 mainly provides support for six boss of pneumatic impact spanner tooling, facilitate pneumatic impact spanner against,
The abrasion of fixed plate 1 is reduced simultaneously, is played the role of buffering, is specifically shown in shown in Fig. 9 and Figure 10.The shape of cushion block 5 is circular ring shape,
Its material is nylon.
Fixed plate 1, limiting plate 2 and cushion block 5 are equipped with center hole 10, and limiting plate is passed through using the extension bar of pneumatic impact spanner
2nd, fastener and mounting structure are fixedly connected by cushion block 5 and the center hole of fixed plate 1.Fastener is fastening bolt, convex
The mounting structure of wheel shaft phase regulator is the center hole at camshaft phase adjuster center.
The external circumferential direction of the center hole 10 of fixed plate 1, limiting plate 2 and cushion block 5 is equipped with corresponding matched guiding
Adjustment hole 11.It is three to be oriented to adjustment hole 11, and three are oriented to the external circumferential direction that adjustment hole 11 is distributed in center hole 10.Three
A distance for being oriented to adjustment hole is equal, in the equilateral triangle that center hole is oriented to that line is formed between adjustment holes in three
The heart is sequentially overlapped installation positioning by being oriented to the setting of adjustment hole 11 convenient for fixed plate 1, cushion block 5 and limiting plate 2.During installation,
Pin can be passed through guiding adjustment hole that the assembly tooling is made to carry out being oriented to adjusting fixation.
The assembly tooling of the camshaft phase adjuster when in use, first by the fixation of one end of positioning pin 3 and fixed plate 2
The installation of hole 7 is fixed, and is then inserted into the other end of positioning pin 3 in the location hole of camshaft phase adjuster 5, later successively will pad
Block 5 and the superposition of limiting plate 2 are got on, specifically as depicted in figs. 1 and 2.Six boss of tooling on pneumatic impact spanner are inserted into followed by
On limiting plate 2 in six cavernous structures 8 with matching, six boss of tooling on pneumatic impact spanner are resisted against on cushion block 5
Formation is fixed, and is then turned on the fastening bolt that pneumatic impact spanner tightens camshaft phase adjuster.It is tightened in fastening bolt
In the process due to the fixation of camshaft phase adjuster assembly tooling, it is possible to avoid the rotation of camshaft phase adjuster, protect
Demonstrate,prove the accuracy of valve timing.Figure 12 is installed in camshaft phase adjuster for the assembly tooling and is looked over from motor head
State.
The present invention is exemplarily described above in association with attached drawing.Obviously, present invention specific implementation is not by above-mentioned side
The limitation of formula.As long as employ the improvement of the various unsubstantialities of inventive concept and technical scheme of the present invention progress；Or not
It is improved, the above-mentioned design of the present invention and technical solution are directly applied into other occasions, in protection scope of the present invention
Within.
