Referring to fig. 1 to 3, the dry type automatic leak detector for the diesel engine body of the invention comprises a base 12 and a support 13, wherein a slide block 5 is arranged on the base 12, the slide block 5 is connected with a transverse movement control mechanism 1 (a transverse movement control oil cylinder), a lifting power source 9 (a lifting oil cylinder) is arranged on the support 13, cylinder hole locking blocks 15 (a plurality of) are arranged below the lifting power source 9 through a longitudinal moving plate 14, and the cylinder hole locking blocks 15 are connected with locking power sources 7 (a plurality of corresponding locking cylinders); two sides of the longitudinal moving plate 14 are provided with a water channel lateral stifling block 6, the water channel lateral stifling block 6 is connected with a lateral stifling block power source 16 (a lateral stifling block cylinder), a side frame 4 is arranged on the base 12 and at the side edge of the sliding block 5, a plurality of water channel positive stifling blocks 17 are arranged on the side frame 4, the water channel positive stifling blocks 17 are connected with a positive stifling block power source 11, and an air pipe 18 is arranged in one of the water channel positive stifling blocks. The positive blank block power source 11 is a positive blank block cylinder which is connected with the air pipe 18, and the other water channel positive blank block (except the water channel positive blank block provided with the air pipe) is externally connected with the cooler closing plate 10; the positive blank block power source 11, the lifting power source 9, the locking power source 7, the lateral blank block power source 16 and the transverse movement control mechanism 1 are respectively and electrically connected with the microcomputer controller 2 with the pressure gauge. And a sealing ring 8 is sleeved at the outer end part of the cylinder hole locking block 15. When in work, the air pipe 18 is inserted into a water channel positive stuffy hole (generally the most lateral one) of a diesel engine body needing to be subjected to leakage detection, and can be directly connected with a positive stuffy block cylinder for air supply. The lifting power source 9, the longitudinal moving plate 14, the cylinder hole locking block 15 (and the sealing ring 8) and the locking power source 7 form the machine body cylinder hole sealing assembly 3. A positioning plate 22 is arranged on the base 12 and at the other side edge of the slide block 5 (corresponding to the position of the side frame 4) so as to position the side surface of the diesel engine body to be subjected to leak detection.
