The exhaust side of lid.The width side of angle and first direction and bottom plate 8 between the axis of beveled aperture and the length direction of cylinder head
Corner dimension between is identical, when cylinder head is in clamping state, the axis of the beveled aperture in cylinder head and the width of bottom plate 8
Direction is parallel, and the machined surface in cylinder head is parallel with first direction, therefore uses the fixture of this structure to cause numerical control
The drill bit of lathe can be advanced along the direction perpendicular with the machined surface in cylinder head, consequently facilitating adding in cylinder head
Work goes out to meet the inclined oil hole of air of technological requirement, it is possible to increase the machining accuracy and processing efficiency of inclined oil hole of air.Beveled aperture and machined surface are simultaneously
On camshaft case 22.
It is used for half finish-milling top surface work step of cylinder head using the fixture of the present invention, bores and attack shield mounting hole work step, bore and attack point
Oily device mounting hole work step, finish ream spark-plug hole work step and bore in beveled aperture work step and fixed for carrying out clamping to cylinder head, can
The reliability for the accurate clamping of cylinder head and positioning, also improving clamping efficiency and compressing is realized, improves cylinder
The machining accuracy of lid, and be used for using same fixture in multiple tooling steps of engine cylinder cap, the versatility of fixture
By force, fixed without carrying out clamping again to cylinder head in each tooling step, improve the machining accuracy of engine cylinder cap
And processing efficiency, be advantageous to the reasonable Arrangement of each tooling step of cylinder head, reduce the input cost of fixture, reduce life
Produce cost.
The present invention is exemplarily described above in association with accompanying drawing.Obviously, present invention specific implementation is not by above-mentioned side
The limitation of formula.As long as employ the improvement of the various unsubstantialities of inventive concept and technical scheme of the present invention progress；Or not
It is improved, the above-mentioned design of the present invention and technical scheme are directly applied into other occasions, in protection scope of the present invention
Within.
