Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
The structural scheme of mechanism of a kind of embodiment of Transmission System of Propulsion Plant inner hole of shaft sleeve boring technological equipment that Fig. 1 proposes for the utility model;
Fig. 2 is the front view of the inner hole of shaft sleeve of Transmission System of Propulsion Plant shown in Fig. 1 boring technological equipment.
Detailed description of the invention
For making the object of the utility model embodiment, technical scheme and advantage clearly, below in conjunction with the accompanying drawing in the utility model embodiment, technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Shown in Fig. 1 and Fig. 2, the Transmission System of Propulsion Plant inner hole of shaft sleeve boring technological equipment disclosed in the present embodiment mainly comprises pedestal 1, and pedestal 1 bottom surface and boring table are closely cooperated and be fixed by bolt.Compared with prior art, pedestal 1 is gone back spaced set and have multiple boss 2.The upper surface of boss 2 offers the first half slot 2-2.As shown in the figure, the internal diameter of the first half slot 2-2 is greater than the external diameter of cardan shaft axle sleeve 5 to be processed, and the first half slot 2-2 is used for carrying out Primary Location to cardan shaft axle sleeve 5, and restriction cardan shaft axle sleeve 5 remains on correct operating position substantially.This Transmission System of Propulsion Plant inner hole of shaft sleeve boring technological equipment also comprises multiple pressing plate 3, and pressing plate 3 and boss 2 one_to_one corresponding are arranged.On the lower surface of pressing plate 3, symmetry offers the second half slot 3-2, and the first half slot 2-2 and the second half slot 3-2 notch are arranged in opposite directions, to form the circular cavity holding cardan shaft axle sleeve 5.An inner washer 4 is also provided with in the circular cavity that every a pair first half slot 2-2 and the second half slot 3-2 are formed.Inner washer 4 comprises the upper semi-ring 4-1 of relative folding and lower semi-ring 4-2.Upper semi-ring 4-1 is arranged on inside the second half slot 3-2, and lower semi-ring 4-2 is arranged on the inner side of the first half slot 2-2.The internal diameter of inner washer 4 is accurately processed according to the normal diameter of cardan shaft axle sleeve 5 external diameter.For the boats and ships of batch production, inner washer 4 can repeatedly reuse.And for the cardan shaft axle sleeve of plurality of specifications, only need produce inner washer 4 according to set specification and can meet different process requirements.
Each group both sides, lower end of pressing plate and boss upper end bilateral symmetry are provided with fixed part 3-1 and 2-1, are bolted between fixed part 3-1 and 2-1.As shown in the figure, due to the thickness between pressing plate 3 and boss 2 more greatly and often need dismounting, for realizing better fastening effect, avoid thread abrasion to damage simultaneously and cause potential safety hazard, connected by studs between fixed part 3-1 and 2-1, so that maintain and replace, reduce the risk occurring security incident.
The step of the Transmission System of Propulsion Plant inner hole of shaft sleeve boring technological equipment adopting the present embodiment to provide is as follows:
