Abstract
The invention discloses a press-fitting fixture for a guide pipe and a seat ring of an air cylinder head. The press-fitting fixture comprises a fixture seat and two pressing heads. Two locating holes are symmetrically formed in the fixture seat, two locating core devices are installed in the two locating holes respectively, and the seat ring and the guide pipe are connected to the locating core devices in a locating and sleeved mode. The lower portions of the pressing heads are connected with the air cylinder head to enable an air inlet valve of the air cylinder head and an exhaust valve of the air cylinder head to be located in the centers of the locating core devices respectively and correspondingly, and power mechanisms are connected to the two pressing heads. The fixture is simple in structure and convenient to operate, enables the guide pipe and the seat ring to be arranged in the air cylinder head in a press-fitting mode at a time, guarantees the press-fitting precision of the guide pipe and the seat ring, and is beneficial for prolonging the service life of the air inlet valve of the air cylinder head and the service life of the exhaust valve of the air cylinder head.
Description
Technical field
The present invention relates to a kind of cylinder head conduit seat ring pressing clamp, be specifically that a kind of cylinder head is enterprising for press-fiting, the pressing clamp of exhaust valve guide and seat ring.
Background technology
Valve stem, valve guide bushing and the seat ring of cylinder head is the key components and parts of composition valve actuating mechanism, wherein conduit and seat ring are installed separately on cylinder head, traditional installation method is: conduit and seat ring are directly knocked in inlet and outlet door, because the inlet and outlet door of cylinder uses frequent, required precision is high, in the time that conduit and seat ring are directly knocked in, has assembling deviation, cannot accurately assemble, cylinder head inlet and outlet door is influenced service life.
Summary of the invention
In order to overcome deficiency of the prior art, the invention provides one simple in structure, easy to operate, can once conduit and seat ring be press-fited in cylinder head, and guarantee that it press-fits precision, be conducive to extend the cylinder head inlet and outlet cylinder head conduit seat ring pressing clamp in service life.
Technical scheme of the present invention is: a kind of cylinder head conduit seat ring pressing clamp, it is characterized in that: comprise clamping fixture seat and two pressure heads, on clamping fixture seat, be symmetrical arranged two locating holes, two locating core devices are installed on respectively in two locating holes, positioning sleeve joint chair circle and conduit on locating core device; Pressure head below connecting cylinder head makes cylinder head be its inlet and outlet door state of corresponding locating core device center respectively, on two pressure heads, is connected with actuating unit.
Described locating core device comprises seat ring core print seat, seat ring core and catheter positioning core, seat ring in-core is cylindrical cavity structure, seat ring outer core is provided with the boss of socket supporting seat ring, catheter positioning core stretches into seat ring in-core chamber by seat ring core upper end and is connected in the spring one end in seat ring in-core chamber, the spring other end is fixed on seat ring in-core chamber through packing ring and jump ring, seat ring core lower end, in seat ring core print seat is fixedly installed in two locating holes, is socketed with the conduit that is supported on seat ring core upper surface on catheter positioning core.
The present invention is in the time press-fiting, two seat ring core print seats are installed in two locating holes of clamping fixture seat, seat ring core is installed on seat ring core print seat, at seat ring outer core socket seat ring, seat ring is supported on boss, on catheter positioning core, is socketed conduit, and catheter support is in seat ring core upper end, and cylinder head is inverted and is connected in pressure head below, startup actuating unit presses down pressure head and drives cylinder head to press down; The inlet and outlet door of cylinder head is just to seat ring and conduit on two seat ring core print seats, press down in process at pressure head, first conduit is pressed in inlet and outlet door, then seat ring is pressed into the valve seating of cylinder head, once press-fited press-fiting of conduit and seat ring, its accurate positioning, press-fits zero deflection, press-fit precision high, be conducive to extend cylinder head inlet and outlet service life.
