2, structure of the present invention is small and exquisite, and manual positioning is fast, can adapt to crankshaft center and float apart from larger size, has reduced the harsh requirement to site environment, has improved the accuracy of leak test;
3, the present invention changes centre distance by gear drive, thereby adapts to the smaller crankshaft end of centre distance;
4, volume of the present invention is little, and same station can configure the plugging mechanism of different cultivars, can under the prerequisite that does not increase operating space, adapt to many kinds flexible production;
5, the present invention is simple in structure, easy to maintenance, safe and reliable, is particularly suited for engine crankshaft end shutoff leak test, also can be used for other revolving shaft class end part seal leak test.
The accompanying drawing explanation
Fig. 1 is structural front view of the present invention;
Fig. 2 is structure vertical view of the present invention;
Fig. 3 is respectively the different use of the present invention view with Fig. 4;
Number in the figure: 1 lifting bolt; 2 fixed handles; 3 shutoff seats; 4 cappings; 5 shutoff cylinders; 6 tighten handle; 7 handle nuts; 8 handle and connecting rods; 9 inner seal rings; 10 exterior seal rings; 11 guide poles; 12 transmission gears; 13 motor bodies; 14 connecting screw rods; 15 block heads; 16 attachment screws; 17 air cylinder connecting rods; 18 fastening screw nuts; 19 crankshaft end.
Embodiment
Referring to Fig. 1 and Fig. 2, in the present embodiment, revolving shaft class end part seal leak test mechanism is:
Block head 15 is sleeved in shutoff seat 3 and can endwisely slips, and a pair of connecting screw rod 14 that can be screwed in the crankshaft end threaded hole is limited in respectively in the two side holes of block head 15; Described a pair of connecting screw rod 14 is provided with transmission gear 12 with tightening between connecting rod 8 of a corresponding side; Between connecting screw rod 14 and transmission gear, and be with the flat key transmitting torque tightening between connecting rod 8 and transmission gear.
The front end of air cylinder connecting rod 17 is fixed in block head 15 by attachment screw 16, and the other end is connected with the piston rod of described shutoff cylinder 5 by fastening screw nut 18.
