Abstract
The utility model discloses a press assembly fixture for a catheter and a seat ring of a cylinder head. The press assembly fixture for the catheter and the seat ring of the cylinder head comprises a fixture seat and two press heads, the fixture seat is symmetrically formed with two locating holes, a locating core device is mounted in each locating hole, a catheter elastic pin and a spring are mounted in each locating hole, the seat ring is placed on the locating core, and the catheter is placed on the catheter elastic pin; the cylinder head is connected under the press heads, the inlet valve of the cylinder head is corresponding to the center of one locating core device while the exhaust valve of the cylinder head is corresponding to the center of the other locating core device, and the press heads are connected with a power mechanism. The press assembly fixture is simple in structure, convenient to operate and capable of mounting the catheter and the seat ring in the cylinder head in a press mode in one time; the press assembly accuracy is guaranteed, and the service life of each of the inlet valve and the exhaust valve of the cylinder head is prolonged.
Description
Technical field
The utility model relates to a kind of cylinder head conduit seat ring pressing clamp, is specifically that a kind of cylinder head is enterprising for press-fiting, the pressing clamp of exhaust valve guide and seat ring.
Background technology
The valve stem of cylinder head, valve guide bushing and seat ring are the key components and parts that forms 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 use of cylinder is frequent, required precision is high, when 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, it is a kind of simple in structure, easy to operate that the utility model provides, and 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.
The technical solution of the utility model 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 utility model is when 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 over against seat ring and conduit on two seat ring core print seats, at pressure head, press down in process, 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.
