Currently, cylinder sleeve 8, which is fitted into cylinder 7, following methods:
1) cylinder sleeve, is tapped using objects such as "painted-face" characters in opera, interference is fitted into cylinder-bore cylinder sleeve under the effect of the pressure；
2), cylinder sleeve is pressed into stepped hole by force using press machine；
But the above two equal existing defects of mounting means: the first installation method is time-consuming and laborious, large labor intensity, dress
With low precision, assembly efficiency is also low, is not suitable for producing in batches, does not also meet the requirement of modern production；Second of installation side
Method is installed because that positive oilhole, can not be relatively specific for the interference of oil-free lubrication cylinder jacket, and is not suitable for general film lubrication cylinder
The installation of set.
Utility model content
The technical problem to be solved by the utility model is to provide a kind of peace in view of the deficiency of the prior art
Quickly and efficiently labour-saving is used for film lubrication cylinder block and cylinder jacket temperature differential method elastic conjunction tool to dress.
The technology employed by the present utility model is a kind of be used for film lubrication cylinder block and the interference of cylinder jacket temperature differential method
Assembly tool, including stull, pull rod, adjustable pressing plate and lifting lug, the stull are laterally installed on two air valve holes of cylinder jacket
Place, the adjustable pressing plate are installed at mounting hole of cylinder sleeve, which is provided with regulating mechanism, for adjusting cylinder jacket oilhole and cylinder
The relative position of oilhole, described pull rod one end connect stull, and the other end is connected after passing through adjustable pressing plate with lifting lug.
According to the above technical scheme, the both ends of the stull are symmetrically arranged with the Step Shaft that outer diameter becomes smaller, the major diameter section of stull
Length is less than the spacing of each limit hole of inner diameter of cylinder sleeve, is equipped with counter sink in the end of Step Shaft.
According to the above technical scheme, supporting plane is equipped on the Step Shaft.
According to the above technical scheme, the centre of the stull is equipped with the tie rod hole for connecting with pull rod screw.
According to the above technical scheme, the regulating mechanism is the adjusting bolt hole for being installed in one end of pressing plate, by adjusting
Bolt is assembled in bolt hole, for the fine tuning in assembling process to cylinder jacket oilhole and the relative position of cylinder oilhole.
According to the above technical scheme, it is equipped with centre bore at the center of adjustable pressing plate, the other end of the pull rod passes through center
Hole.
The utility model has the following beneficial effects: stull lifts by crane cylinder sleeve, adjustable pressure by valve opening on cylinder sleeve in assembling process
Plate is pressed at the stepped hole of cylinder jacket for limiting and lifting.Cylinder jacket is lifted by crane from liquid nitrogen cylinder using lifting device, and gas is loaded on
In cylinder, to realize the temperature differential method elastic conjunction of cylinder jacket, entire assembling process is convenient and efficient, and precision is high, highly-safe；Because
Cylinder is that 230 DEG C are heated into infrared furnace, by the way that adjustable mechanism is arranged, convenient for oilhole to just, preventing from scalding
Wound, further improves the security performance of assembly.

Specific embodiment
As shown in Figure 2-5, it present embodiments provides a kind of for film lubrication cylinder block and cylinder jacket temperature differential method interference dress
With tool, including stull 1, pull rod 2, adjustable pressing plate 3 and lifting lug 4, the stull 1 is laterally installed on two gas of cylinder jacket 8
At valve opening 81, the adjustable pressing plate 3 is installed at mounting hole of cylinder sleeve 71, which is provided with regulating mechanism, for adjusting cylinder jacket
The relative position of oilhole 82 and cylinder oilhole 73, described 2 one end of pull rod connect stull 1, the other end pass through after adjustable pressing plate 3 with
