Abstract
The utility model provides an auxiliary tool for assembling a shaft coupling. The auxiliary tool comprises an air pick which is composed of a barrel, a handle, a handle, an air distribution mechanism and an impact mechanism, and a propulsion disc; a tail rod of the propulsion disc is inserted in the front end of a cylinder of the impact structure. The propulsion disc is composed of two split parts, namely a circular body and the tail rod, and the two split parts are integrally connected by a fastener. The auxiliary tool is obtained by virtue of modification on the basis of the existing air pick and by utilizing the propulsion disc instead of a pick rod. In use, based on the working principle of the air pick, the propulsion disc is enabled to strike the shaft coupling; as the circular body of the propulsion disc is matched with the end face of the shaft coupling in shape, the striking force can be ensured to be axial force conveniently, and therefore, a coupling shaft can be protected against damage and even a key slot can be prevented from being endangered; the auxiliary tool has the advantages of time saving, labor saving and high efficiency.
Description
Technical field
The utility model belongs to a kind of instrument of auxiliary assembling, especially belongs to a kind of for assembling the aid of shaft coupling.
Background technology
The effect of shaft coupling is that diaxon is linked together, and realizes the interlock of driving shaft and driven shaft, if connect badly, will certainly affect the normal work of transmission system.Fig. 1 shows the assembly structure of a kind of shaft coupling a and axle head c, and during practical set, because shaft coupling a and axle head c are close-fitting structures, assembly crewman is difficult to shaft coupling a to be in place, and therefore, need to by the direction of arrow in figure, impact by instrument, just can complete.Problem is: the efficiency that wastes time and energy is low, especially, because impact force can not remain axially, therefore can damage coupling spindle, even jeopardize keyway b, and impact connects effect.
Summary of the invention
For solving the problems of the technologies described above, the utility model aims to provide a kind of aid that assembles shaft coupling, relies on this instrument not only can assemble easily shaft coupling, and there will not be damage coupling spindle, the advantage that even jeopardizes keyway.
For solving the problems of the technologies described above, the utility model has adopted following technical proposals, the aid of this assembling shaft coupling, it is characterized in that: comprise the pneumatic pick being formed by cylindrical shell, handle, handgrip, valve actuating mechanism and beater mechanism, and a pushing disc, the foot piece of this pushing disc inserts the cylinder front end of described beater mechanism.
Further, described pushing disc is comprised of round and foot piece two parts of split, and is connected into integral body by securing member.
Beneficial effect: the utility model substitutes pick rod with pushing disc, improves and forms on existing pneumatic pick basis.During use, utilize pneumatic pick operation principle, make pushing disc enter to beat shaft coupling; because round and the shaft coupling end face shape of pushing disc are suitable, therefore can guarantee easily that impact force is axial force, thereby avoid damaging coupling spindle; even jeopardize keyway, have advantages of that time saving and energy saving efficiency is high.
Below in conjunction with accompanying drawing, by embodiment, the utility model is described further.
Accompanying drawing explanation
Fig. 1 is workpiece assembly structure schematic diagram.
Fig. 2 is the side structure schematic diagram of an embodiment of this utility structure.
Fig. 3 is the perspective view of pushing disc in Fig. 2.
In figure: shaft coupling a, keyway b, axle head c, cylindrical shell 1, handle 2, pushing disc 3, foot piece 31, flange 4, airduct 5, handle 6.
The specific embodiment
Referring to Fig. 1.Because pneumatic pick structure is prior art structure, therefore, do not remake a step and repeat.Foot piece 31 structures of pushing disc 3 are identical with the tail structure of existing pick rod, under the tup effect of pneumatic pick, make pushing disc 3 make axially reciprocating, realize impacting shaft coupling.Pushing disc 3 consists of round and foot piece 31 two parts of split, by securing member, is connected into integral body, to according to shaft coupling tail end size, select suitable pushing disc 3 rounds.
Above-described embodiment is only explanation flesh and blood of the present utility model, and should not be considered as the concrete restriction to the utility model structure, and any simple deformation design of having done according to embodiment, all should include protection domain of the present utility model in.
