Detailed description of the invention
With reference to Fig. 1-6, the drilling tool in a kind of crankshaft-flywheel hole, including pedestal 50, pedestal 50 includes riser
51, riser 51 is provided with least one set bent axle clamping mechanism, described bent axle clamping mechanism includes being arranged on
Riser 51 side and the 5th trunnion clamp assemblies 10 being from top to bottom sequentially arranged, the clamping of four main neck
Part 20, first connecting rod neck holder 30 and the first trunnion clamp assemblies 40.
5th trunnion clamp assemblies 10 includes the V-type clamp 11 fixed vertical with riser 51, and with vertical
The gripper shoe 15 that plate 51 is vertically fixed, gripper shoe 15 is hingedly connected with and coordinates card for V-type clamp 11
Holding the snap fit plate 12 of trunnion, snap fit plate 12 connects to be had for driving snap fit plate 12 to rotate around pin joint
Drive rod 14, drive rod 14 is connected through riser 51 with the actuator being positioned at riser 51 opposite side.Hold
Row mechanism is preferably hydraulic jack.
So that snap fit plate 12 is after clamping terminates, it is possible to Quick-return to original position, convenient taking-up
Bent axle 60, is therefore additionally provided with the spring for accommodating drive rod 14 in riser 51 side connecting actuator
Sleeve pipe 17, is provided with the back-moving spring 16 resetted for drive rod 14 in pogo barrel 17.
The structure of the first trunnion clamp assemblies 40 uses the structure identical with the 5th trunnion clamp assemblies 10.
In order to avoid clamp assemblies is when clamping bent axle 60, V-type clamp 11 scratches trunnion, V-type clamp
Two inner sides of 11 are all embedded with rubber cushion block 13.
Four main neck holder 20 uses the plate of U-shape structure, and is vertically fixed on riser 51.The
Four main neck holder 20 mainly relies on its upper surface that the thrust surface of bent axle 60 is formed location, therefore exists
The upper surface of four main neck holder 20 is embedded with the glue gasket 21 protruding this surface, it is to avoid four main
The thrust surface of bent axle 60 is damaged by neck holder 20.
First connecting rod neck holder 30 uses elastic clip, it is possible to by rapid for the first connecting rod neck 63 of bent axle 60
Snap in first connecting rod neck holder 30, fixation；During taking-up, it is possible to directly take out, very convenient.
With reference to Fig. 1 and Fig. 7, the drilling tool of bent axle 60 flywheel hole of the present utility model, the 5th trunnion folder
Holding the 5th trunnion 61 that assembly 10 is clamping bent axle 60, four main neck holder 20 clamps bent axle 60
Four main neck 62, first connecting rod neck holder 30 clamps the first connecting rod neck 63 of bent axle 60, first
Trunnion clamp assemblies 40 clamps the first trunnion 64 of bent axle 60, first by bent axle 60 according to this order
Snapping in each clamping or fastening part, four main neck holder 20 is U-shape structure, depends primarily on it
The thrust surface of bent axle 60 is supported by upper surface, thus forms the axial location to bent axle 60, and first is main
Axle journal clamp assemblies 40 and the 5th trunnion clamp assemblies 10, be all to be driven by actuators such as oil cylinders to drive
Lever 14 action, is driven snap fit plate 12 to rotate around the pin joint in gripper shoe 15, so by drive rod 14
Coordinate with V-type clamp 11 afterwards, form the first trunnion 64 and the 5th trunnion 61 to bent axle 60 and formed
Clamping；And first connecting rod neck holder 30 is elastic clamping mechanism, it is achieved first connecting rod neck 63 is formed folder
After holding, it is possible to effectively prevent bent axle 60 in the rotation of circumference.Finally, by the 5th trunnion clamp assemblies
10, four main neck holder 20, first connecting rod neck holder 30 and the first trunnion clamp assemblies 40
Common effect, completes gripping bent axle 60.After fixing, the operations such as boring can be started.Boring
After completing, unclamp the 5th trunnion clamp assemblies 10 respectively and the first trunnion clamp assemblies 40 i.e. can be taken off
Bent axle 60, completes drilling operating.
