Detailed description of the invention
Below against accompanying drawing, by the description to embodiment, the detailed description of the invention of the present invention is made further details of
Explanation, it is therefore an objective to help those skilled in the art that design, the technical scheme of the present invention are had more complete, accurate and deep reason
Solve, and contribute to its enforcement.
As depicted in figs. 1 and 2, the invention provides a kind of engine crankshaft damper pulley signal gear Gear Milling to use
Fixture, including base plate 2, is arranged on base plate 2 and for signal gear providing the gasket ring 5 supported, for by signal teeth wheel load
Tight compressing member on gasket ring 5 and for the locking device making compressing member lock.
Specifically, as depicted in figs. 1 and 2, base plate 2 is rectangular flat, and gasket ring 5 is vertically arranged on the end face of base plate 2,
Gasket ring 5 is cirque structure, and the inside of gasket ring 5 is the cavity accommodating signal gear, the end face phase of the axis of gasket ring 5 and base plate 2
Vertically.When installing signal gear, the hub portion of signal gear is sunk in the cavity in gasket ring 5, signal gear is formed
The flange portion of the gear teeth is positioned on the end face of gasket ring 5, makes flange portion in the state perpendicular with base plate 2, it is simple to milling cutter enters
Row Gear Milling.
As preferably, as it is shown in figure 1, gasket ring 5 is connected by screw is fixing with base plate 2, easy accessibility.Screw edge week
Multiple to being uniformly arranged, improve the reliability that gasket ring 5 is connected with base plate 2.
As shown in figures 1 and 3, compressing member includes the pressing plate 3 being oppositely arranged with gasket ring 5 and the hands that be connected fixing with pressing plate 3
Bar 4.Pressing plate 3 is for applying downward thrust to signal gear, and match the flange of clamping signal gear with the gasket ring 5 of lower section
Part, namely fixed signal gear.Pressing plate 3 is disc-shaped structure, and the length direction of hand lever 4 is paralleled with the RADIAL of pressing plate 3,
The end of hand lever 4 and pressing plate 3 be fixing to be connected and stretches out towards the outside of pressing plate 3, and the setting of hand lever 4 is easy for picking and placeing of compressing member
And movement.
As it is shown in figure 1, locking device includes check lock lever 8 and is sheathed on check lock lever 8 and is threaded with check lock lever 8
First locking nut 9, check lock lever 8 is through base plate 2 and pressing plate 3, and base plate 2 has the screwed hole allowing check lock lever 8 pass.Check lock lever 8
Outer surface be provided with external screw thread, one end of check lock lever 8 is the projection of the diameter of set screwed hole with sizes greater than on base plate 2,
First locking nut 9 overlaps check lock lever 8 at the other end of check lock lever 8.Check lock lever 8 with base plate 2 for threadeding, check lock lever 8 edge
After vertical direction upwards sequentially passes through base plate 2 and pressing plate 3, tighten the first locking nut 9 above pressing plate 3, make the first locking screw
Female 9 clamping platens 3, and then make pressing plate 3 compress signal gear.
