Description
Technical field
The utility model relates to a kind of extracting tool, especially the provision for disengagement of engine cylinder head valve collet.
Background technology
Engine production enterprise is when sending product motorcycle general assembly factory to inspect examination by random samples, if find that in a collection of product substandard product is arranged, then entire block all will be returned and dismantle, and part that will be defective in quality is ressembled after replacing.Therefore, engine production enterprise generally all is provided with special dismounting workshop and does this work.The part that has is easy to dismounting, and the part that has removes just very difficult because assembling is special.Dismounting as the engine cylinder head valve collet, conventional method is that the dismounting workman will be placed on the cotter seat towards an end of tearing head open, make the valve stem centrally aligned dash the resigning hole of tearing head open, hit with a hammer then and dash the other end of tearing head open, make cotter seat overcome the elastic force of valve spring, separate with valve collet, two valve collets drop from valve stem, then the cotter seat on the valve stem, valve spring etc. are taken off.Owing to cooperates very tightly between cotter seat and the valve collet, to tear open under the powerful impact force action of a moment dashing, valve collet is easy to move together and be stuck on the valve stem with cotter seat, causes difficulty to dismounting, and dismounting is required great effort, efficient is low.
The utility model content
The purpose of this utility model provides the provision for disengagement of a kind of engine cylinder head valve collet, when solving traditional-handwork dismounting engine cylinder head valve collet, valve collet is easy to be stuck on the valve stem with cotter seat, and inconvenient operation, effort, inefficient problem.
Engine cylinder head valve collet described in the utility model provision for disengagement, comprise dashing and tear head open, dash to tear open resigning hole is arranged on the head, dash the top of tearing head open and be provided with cylinder block, cylinder block is installed on the frame, dashes the upper end of tearing head open and is fastened on the axis of the piston of cylinder block, dash the below of tearing head open and be provided with cylinder head pressure-bearing platform, cylinder head pressure-bearing platform face up is the inclined-plane, and two air pipe interfaces of cylinder block are connected an end of foot-operated air valve switch respectively by tracheae, and the other end of foot-operated air valve switch is connected on the source of the gas pipeline.
Be installed on the cylinder block towards tearing head open in the utility model, with pneumatic replacement tradition manpower, strength is big and steady, more help the reliable separation between cotter seat and the valve collet, because valve stem, valve spring etc. are oblique being installed on the engine cylinder head, therefore cylinder head pressure-bearing platform face up is set to the inclined-plane, after engine cylinder head is placed on above the cylinder head pressure-bearing platform, make valve stem, valve spring etc. vertically upward, be convenient to bear the impulsive force of tearing a vertical direction from the cylinder block upper punch open.
The utility model has the advantages that: simple to operate, laborsaving, a people just can independently finish, and the production efficiency height.
Description of drawings
The utility model is described in further detail below in conjunction with the drawings and the specific embodiments:
Fig. 1 is a front view of the present utility model;
Fig. 2 is the left view of Fig. 1.
The specific embodiment
As Fig. 1, shown in Figure 2, the utility model tears 1 open by dashing, resigning hole 2, cylinder block 3, frame 4, cylinder head pressure-bearing platform 5, tracheae 6, tracheae 7, foot-operated air valve switch 8, adjustable platen 9 and bolt 10 constitute, dash to tear open on 1 resigning hole 2 is arranged, dash and to tear a top of 1 open and be provided with cylinder block 3, cylinder block 3 is installed on the frame 4, dash and to tear a upper end of 1 open and be fastened on the axis of the piston 3a of cylinder block 3, dash and to tear a below of 1 open and be provided with cylinder head pressure-bearing platform 5, cylinder head pressure-bearing platform 5 face 5a up is the inclined-plane, two air pipe interfaces of cylinder block 3 are respectively by tracheae 6,7 are connected an end of foot-operated air valve switch 8, and the other end of foot-operated air valve switch 8 is connected on the source of the gas pipeline.Described dash torn a upper end of 1 open and is threaded on the axis of the piston 3a of cylinder block 3, to be convenient for changing.
Can find out from Fig. 1, Fig. 2: described cylinder head pressure-bearing platform 5 face 5a dual-side and base up is respectively arranged with positive stop 11,12, engine cylinder head is placed on when dismantling on the cylinder head pressure-bearing platform 5, can prevents that engine cylinder head from arbitrarily moving on cylinder head pressure-bearing platform 5.
Fig. 1 also illustrates, described cylinder head pressure-bearing platform 5 is placed on the adjustable platen 9, the two ends of adjustable platen 9 are installed on the frame 4 by bolt 10, therefore can carry out height to adjustable platen 9 according to the engine cylinder head of different model and regulate, with satisfy the engine cylinder head cotter seat with towards a required distance of tearing 1 open.
During use, connect total gas source switch, engine cylinder head to be removed is placed on the cylinder head pressure-bearing platform 5, make valve stem, valve spring etc. vertically upward, and be with slightly with hand and buttress cylinder head pressure-bearing platform 5, with cotter seat with dash tear open 1 relative, and the valve stem centrally aligned is dashed tear open 1 resigning hole 2, tramp with one's feet then and move foot-operated air valve switch 8, the axis of the piston 3a of cylinder block 3 drives to dash and tears 1 motion vertically downward, impact cotter seat open, cotter seat is separated with valve collet, so it is loosening to hug two valve collets of valve stem, separates from valve stem, thereby finishes dismantlement work.
