Specific embodiment
The present invention is further described for explanation and specific embodiment below in conjunction with the accompanying drawings.
As shown in Figures 1 to 9, the new type crank belt pulley bolt fixture, including supporting mechanism, drive module
And locating module, the supporting mechanism include support column 24, base 23, parallel slide rail 22 and slide unit 21, the driving mould
Block includes cylinder 10, and the locating module includes alignment pin 00, match block 01, supports block 02, guide rod 03 and fixed plate 05, institute
State alignment pin 00 to be secured by bolts in match block 01, the match block 01 is fixed on the support by dormant bolt 010
On block 02, the support block 02 is secured by bolts on slide unit 21；One end of the guide rod 03 is fixed on support block 02, and
The other end is connected by shaft coupling 04 through the hole in fixed plate 05 with cylinder 10, and the fixed plate 05 is secured by bolts in
On the base 23, the alignment pin 00, match block 02, support block 03, guide rod 03, fixed plate 05 and cylinder 10 and bent axle method
Blue end pilot hole 301 is on the same axis.The support block 02 is individually fixed on slide unit 21 and base 23 with fixed plate 05, is risen
The effect of whole new type crank belt pulley bolt fixture is fixed to support.The slide unit 21 towards the one side of base 23 have with
Sliding wheel or coasting mechanism that the parallel slide rail 22 mutually agrees with so that cylinder 10 promotes slide unit 21 to move.The parallel cunning
Rail 22 is fixed on base 23, and base 23 is fixed on the support column 24 by fixed mechanism, four legs of support column 24
Or three legs, smoothly it is placed on ground, have for by the support column 24 on the part on the laminating of the support column 24 ground
It is fixed on ground or fixed part elsewhere.
As described in Fig. 4 to 6, there is some for match block 01 to be fixed on the support block 02 in the match block 01
, with the support block 02 be fixed together match block 01 using dormant bolt so that dormant bolt is complete by dormant bolt hole 010
It is contained in the dormant bolt hole 010, it is to avoid dormant bolt frequently contact dormant bolt abrasion, the slip for causing with the external world
The problems such as, and cause match block 01 and support to be loosened between block 02, influence new type crank belt pulley bolt fixture fixes bent
The effect of axle.Also include two or more fixing hole 011 in the match block 01, the fixing hole 011 is circular arc elongated hole or half
Month shape arcuate socket so that the fixing hole 011 can easily accommodate the technique spiral shell on flange end in flywheel screwed hole 300 very much
Bolt.
As shown in Figure 6 and Figure 7, the center of the match block 01 is provided with determining for the fixation alignment pin 00
Position pin mounting hole 012, the alignment pin 00 include the screwed location division that matches with the alignment pin mounting hole 012 and
Inside there is the location division of cavity.The alignment pin 00 is inserted in crankshaft flange end pilot hole 301, flywheel screwed hole on bent axle
Service bolt in 300 is inserted in the fixing hole 011 in the match block 01, the two mutual cooperation, and bent axle is firmly fixed
Firmly.The head of the service bolt is regular hexagon, facilitates operative employee that service bolt is screwed into flywheel spiral shell using air gun jacketed cylinder
In pit 300.It is strengthening process bolt strength, reduces the abrasion of service bolt, the service bolt is gone forward side by side using the processing of 45# steel
Row Darkening process.
The new type crank belt pulley bolt fixing means includes：
A. be screwed into service bolt in the crankshaft flange end flywheel screwed hole 300 of engine by operator；
B. when station where engine reaches new type crank belt pulley bolt fixture, new type crank belt pulley spiral shell is started
Bolt fixing device；
C. new type crank belt pulley bolt fixture is fixed to bent axle automatically；
D. operator's fixed crankshaft belt pulley bolt；
E. new type crank belt pulley bolt fixture reinstatement state, operator back-outs crankshaft flange end flywheel screwed hole 300
In on service bolt.
Be screwed into service bolt in the crankshaft flange end flywheel screwed hole 300 by upper operative employee, and engine enters described
Station where new type crank belt pulley bolt fixture, starts the new type crank belt pulley bolt fixture, cylinder 10
Drive leader 03 extends, while guide rod 03 promotes slide unit 21 to move forward, it is right that alignment pin 00 is carried out with alignment pin mounting hole 012
Connect, fixing hole 011 is docked with crankshaft flange end pilot hole, because in advance by crankshaft flange end flywheel screwed hole 300
Service bolt position adjustment be it is identical with the position of fixing hole 011 in match block 01, and fixing hole 011 be more than the work
Skill bolt head external diameter, so docking is easy to successfully, and crankshaft flange end pilot hole 301 also functions to a guiding alignment pin 00
Direction effect.Treat that bent axle is fixed successfully, the stop motion of cylinder 10, operative employee is fixed behaviour to crank pulley bolt
Make, after the completion of the operation of fixed crankshaft belt pulley bolt, the drive leader 03 of cylinder 10 is moved rearwards by, cancel the fixed behaviour to bent axle
Make, set back and put, engine shifts to next station, and the next operative employee backs out the service bolt on bent axle.
Above content is to combine specific preferred embodiment further description made for the present invention, it is impossible to assert
Specific implementation of the invention is confined to these explanations.For general technical staff of the technical field of the invention,
On the premise of not departing from present inventive concept, some simple deduction or replace can also be made, should be all considered as belonging to of the invention
Protection domain.
