Abstract
The utility model discloses a device for preventing neglected machining of a chamfer of a valve seat ring. The device comprises a valve seat ring moving walkway which is formed by an outer baffle plate, an inner baffle plate and a base plate; the outlet of the valve seat ring moving walkway is provided with a neglected machining block; one corner of the lower portion of the neglected machining block is provided with a gap for the valve seat ring to move; the upper portion of the gap is provided with a gap chamfer which is corresponding to the seat ring chamfer. According to the device for preventing the neglected machining of the chamfer of the valve seat ring, the neglected machining of the chamfer of the valve seat ring can be avoided and the damage of an engine and related components due to the fact that an unqualified product of the valve seat ring enters into the engine due to the neglected machining can be avoided.
Description
Technical field
the utility model relates to a kind of valve retainer chamfering leakage processing unit (plant) that prevents.
Background technology
At present each main engine plants mostly adopt under normal temperature or liquid nitrogen state valve retainer are pressed into engine cylinder cover place, so need to there be chamfer design at valve retainer periphery place, and object is to play a guiding role while being pressed into cylinder cap bottom outlet for seat ring, conveniently press-fits.In process, there is omission processing phenomenon continuously in valve retainer chamfer machining, if chamfering is omitted converted products inflow, main engine plants are pressed in cylinder cap by mistake, can cause the serious scratch of cylinder cap bottom outlet wall to destroy or press-fit the valve retainer that causes not in place comes off, when high engine speeds turns round, cause other associated components to damage together, engine is scrapped.
Summary of the invention
the purpose of this utility model is to provide a kind of device that can prevent valve retainer chamfering leakage processing.
A kind of valve retainer chamfering leakage processing unit (plant) that prevents of the present utility model, comprise the valve retainer moving walkways being formed by outer baffle, Internal baffle and base plate, outlet at described valve retainer moving walkways is provided with leakage processing block, one jiao of described leakage processing block bottom is provided with the breach that can allow valve retainer to move, and the top of described breach is provided with the breach chamfering corresponding with seat ring chamfering.
Described leakage processing block is bolted on outer baffle.
Processing unit (plant) of the present utility model can avoid valve retainer chamfering to leak processing problems, avoids valve retainer to pack owing to leaking processing defective work the damage that causes engine and associated components in engine into.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
The state diagram that Fig. 2 is valve retainer when leaking processing block.
In figure: 1, outer baffle; 2, Internal baffle; 3, connecting plate; 4, leak processing block; 5, base plate; 6, valve retainer; 7, breach chamfering; 8, seat ring chamfering; 9, breach.
The specific embodiment
As shown in Figure 1 and Figure 2, the valve retainer chamfering leakage processing unit (plant) that prevents of the present utility model, comprise the valve retainer moving walkways being formed by outer baffle 1, Internal baffle 2 and base plate 5, outlet at described valve retainer moving walkways is provided with Lou processing block 4, one jiao of described leakage processing block 4 bottoms is provided with the breach 9 that can allow valve retainer 6 to move through, the top of described breach 9 is provided with the breach chamfering 7 corresponding with seat ring chamfering 8 positions and shape, makes the qualified valve retainer product with seat ring chamfering 8 just in time can pass through breach 9; Described leakage processing block 4 is bolted on outer baffle 1.For seat ring chamfering, leak the product of processing, when through aisle, can interfere with device, cannot pass through device, and the normal product that are processed with seat ring chamfering can pass through device.Processing unit (plant) of the present utility model can avoid valve retainer chamfering to leak processing problems, avoids valve retainer to pack owing to leaking processing defective work the damage that causes engine and associated components in engine into.
Claims (2)
1. one kind prevents valve retainer chamfering leakage processing unit (plant), comprise the valve retainer moving walkways being formed by outer baffle (1), Internal baffle (2) and base plate (5), it is characterized in that, outlet at described valve retainer moving walkways is provided with Lou processing block (4), one jiao of described leakage processing block (4) bottom is provided with the breach (9) that can allow valve retainer (6) mobile, and the top of described breach (9) is provided with the breach chamfering (7) corresponding with seat ring chamfering (8).
