Abstract
The utility model discloses a machining and fixing clamp of an engine air cylinder cover. The machining and fixing clamp of the engine air cylinder cover comprises a fixing board with the bottom face supported by at least four telescopic supporting components. The top end of each telescopic supporting component is connected with the bottom face of the fixing board through a universal joint and the supporting angle can be changed. A numerical control unit can detect whether the top face of the air cylinder cover is horizontal or not according to two angle detection units which are perpendicular to each other and control one or two or three telescopic supporting components to extend or retract so that the top face of the air cylinder cover can be horizontal.
Description
Technical field
The utility model relates to engine cylinder cap processing technique field, relates in particular to a kind of engine cylinder cap processing retaining clip tool.
Background technology
Engine cylinder cap belongs to valve actuating mechanism at internal combustion engine, is mainly for closed cylinder top, forms combustion chamber, and as the support of camshaft and rocker arm shaft and air inlet-outlet pipe.During cylinder operation, air is drawn onto to cylinder interior, spark plug is lighted burning mixture, drives piston acting, and waste gas is discharged from blast pipe.Cylinder head can be divided into: L-head cylinder cylinder head, comprises water jacket, inlet opening, apopore, spark-plug hole, bolt hole, combustion chamber; Overhead valve engine cylinder head, except cooling jacket, also has valve gear, air inlet and exhaust passage etc.
Precision in engine cylinder cap process directly affects the product quality of engine cylinder cap, and because cylinder hd top face has certain angle, if cylinder head bottom surface level is fixed, cylinder head end face tilts, and difficulty of processing is larger.In order to ensure cylinder head, after clamping, still keep machine tool and the processing of cylinder head end face vertical direction, cutter need to have certain angle of inclination, generally need to take a long time adjustment machining angle, larger to cylinder head machining accuracy and effectiveness affects.
In prior art, by holding part, adjust the angle of fixed head, make cylinder head end face level, to overcome the problem in above-mentioned processing.Yet the mode of this adjustment fixed head angle is monolateral form normally, one end of fixed head connects base, and the other end is by holding part jack-up or put down.Must be accurately when this just requires on fixed head fixed air cylinder cap, if angle deviation to some extent cannot realize end face level.
Utility model content
In order to solve the technical problem existing in background technology, the utility model proposes a kind of engine cylinder cap processing retaining clip tool, so that cylinder head end face level is convenient to tool sharpening, improved machining accuracy and efficiency.
A kind of engine cylinder cap processing retaining clip tool the utility model proposes, comprising:
Base, described base top surface is plane;
Fixed head, for described base top surface match tabular, be arranged on described base top surface, for fixed air cylinder cap bottom;
At least four piston support components, comprising: piston/cylinder, is arranged on the container cavity in described base; Piston rod, vertical with described base top surface, by universal joint, be connected with described fixed head bottom surface;
At least two angle detecting units, are positioned on described fixed head, mutually vertical with the line of centres of described fixed head, for detect the angle of described fixed head and horizontal plane from orthogonal both direction;
Numerical control unit, be electrically connected to the drive division of described angle detecting unit and piston support component, be used for controlling driver part by described fixed head jack-up to level, and the angle information sending according to described angle detecting unit and the cylinder head end face setting in advance and the angle information of horizontal plane, judge whether level of cylinder head end face, operating period is adjusted by described angle detecting unit detection information, until described cylinder head end face level.
Preferably, described fixed head is fixed described cylinder head by locking pin or fixed card relay part.
Preferably, described piston support component is air rammer or fluid-operated piston.
Preferably, described angle detecting unit, is positioned at described fixed head end face or bottom surface.
In the utility model, at least four retractable support member supporting of fixed head underrun, the top of each retractable support parts is connected with fixed head bottom surface by universal joint, can change support angle; Numerical control unit can be according to orthogonal two angle detecting units, detect whether level of cylinder head end face, control one of them, two, three retractable support parts stretch out or retract, so that cylinder head end face level.
