Specific embodiment
Hereinafter embodiments of the present invention are illustrated by particular specific embodiment, those skilled in the art can be by this explanation
Content disclosed by book understands other advantages and effect of the present invention easily.
Refer to Fig. 1 to Fig. 5.In order to describe the present invention in detail, next the present invention is illustrated：Slide block
Formula is stretched self-centering hydraulic pressure center frame, including base 15, is provided with rectangular channel, is provided with slidably in rectangular channel in the middle part of this base 15
Slide block 12.Also include the cover plate coming off in base for anti-limited slip block 12, cover plate is arranged on base 15 by bolt.
There is connecting plate 2 in the bolt connection that passes on left of base 15, connecting plate 2 be provided with hydraulic jack 1 by bolt,
The piston rod of hydraulic jack 1 stretches into the right rectangular channel and has been threaded connection connecting pin 16, and the other end of connecting pin 16 is T
Type, makes slide block 12 and connecting pin 16 connect by opening up T-shaped draw-in groove accordingly on slide block 12.So setting is it is possible to pass through
Hydraulic jack 1 drives slide block 12 to horizontally slip on base 15.
The right side central of slide block 12 is provided with side pressing block 7 by bolt, and the obverse and reverse of slide block 12 is symmetrically provided with two
The slide block slot 11 of individual inclination, the slide block slot 11 of wherein lower section is inclined upwardly by the downside of slide block 12 and extends to the right side of slide block 12
It is provided with upper pressing arm in the top of side pressing block 7, and the slide block slot 11 of lower section.The slide block slot 11 of top is downward by the upside of slide block 12
Tilt and extend to the lower section of the right side side pressing block 7 of slide block 12, and in the slide block slot 11 of top, be provided with hold 17, upper pressing arm
Right-hand member stretches out slide block slot 11 and is connected with upper holder block 8, and hold 17 right-hand member stretches out slide block slot 11 and is connected with lower lock block 9.So
Setting, is moved so that it may so that upper holder block 8 and lower lock block 9 move up and down in slide block slot 11 by upper pressing arm and hold 17, and
Form at 3 points with side pressing block 7 and support bent axle simultaneously.
Symmetrical in base 15 be provided with upper and lower two cam paths 3, camshaft bearing 4, camshaft are installed in cam path 3
Hold 4 and include roller 41 and roller 42.Cam path 3 level of upside is arranged from left to right, is folded upward on right side, and in cam path
3 right-hand members setting mounting grooves, are provided with hold fine adjustment block 6 in mounting groove, and the left side wall of hold fine adjustment block 6 caves inward use
Move upwards in drive cam bearing 4.And it is provided with installing hole in the lower end of this hold fine adjustment block 6, this installation in the hole is provided with bullet
Spring so that installing hole is stretched in one end of spring, the other end and mounting groove contact internal walls, and on base 15 with hold fine adjustment block
At 6 corresponding positions, hold fine adjustment screw 5 is installed, as long as it is micro- to make mounting groove length in the vertical direction be more than hold
Adjustable block 6, thus can adjust the position on hold fine adjustment block 6 above-below direction in mounting groove by hold fine adjustment screw 5
Put, adjust motion in cam path 3 for the camshaft bearing 4, thus adjusting motion in slide block slot for the hold 17 so that upper pressing arm
Motion with hold 17 is first coordinated, and reaches the purpose of precision centering.The cam path 3 of downside, upper pressing arm fine adjustment block 13, upper pressing arm
Fine adjustment screw 14 is arranged in the same manner.
In addition, the hole of roller 42 insertion for camshaft bearing 4 is provided with upper pressing arm and hold 17, and set on slide block 12
There is the long lumbar hole that the roller 41 for camshaft bearing 4 passes through.
So arrange, during original state, camshaft bearing 4 is located at the horizontal segment of cam path 3, starts hydraulic jack 1, makes hydraulic pressure
Oil cylinder 1 drives slide block 12 to move right, and slide block 12 drives camshaft bearing 4 level to move right by long lumbar hole simultaneously, and due to
Camshaft bearing 4 in the vertical direction does not move, so upper pressing arm and hold 17 only move right with slide block 12.When top
When camshaft bearing 4 moves to the right-hand member of cam path 3, because the effect of hold fine adjustment block 6 makes camshaft bearing 4 move upwards, with
When by roller 42 drive hold 17 move upwards along slide block slot 11, lower lock block 9 kinematic mount upwards of hold 17 right-hand member
Bent axle.In the same manner for upper pressing arm and upper holder block 8.Because slide block slot 11 and upper pressing arm, hold 17 are all symmetrical arranged, more than press
Block 8 and lower lock block 9 can also pass through upper pressing arm fine adjustment screw with self-centering if centering is not accurate when near bent axle
14 or hold fine adjustment screw 5 adjust.
In addition, upper holder block 8, lower lock block 9 and side pressing block 7 and the contact surface of bent axle are provided with diamond wear proof pad 10, gold
Hard rock wear-resistant pad 10 side is cylinder, and upper holder block 8, lower lock block 9 and side pressing block 7 are equipped with the adjustment tank of cylinder.This
Sample is arranged, and diamond wear proof pad 10 can swing thus more fitting with the surface of bent axle.And diamond wear proof pad 10 and bent axle
Contact surface passes through raising fineness and can avoid damage to crankshaft surface.
Above-described embodiment only principle of the illustrative present invention and its effect, not for the restriction present invention.Any ripe
The personage knowing this technology all can carry out modifications and changes without prejudice under the spirit and the scope of the present invention to above-described embodiment.Cause
This, those of ordinary skill in the art is complete with institute under technological thought without departing from disclosed spirit such as
All equivalent modifications becoming or change, must be covered by the claim of the present invention.
