Abstract
The utility model provides an extractor for a part of a blind hole. The adopted technical scheme includes that: the extractor comprises semi-circular wedges, elastic rings, pressing covers, an adjusting nut, an ejector rod, a punching and pulling device and screws; the two semi-circular wedges of same structures are symmetrically positioned; a conical claw is arranged at the left end surface of each semi-circular wedge and an elastic ring is arranged at the circumferential surface at the right end of each semi-circular wedge; the screws sequentially penetrate through the pressing covers and waist-shaped holes in convex lugs of the semi-circular wedges and then are in threaded connection with the adjusting nut and enable the pressing covers to be fixedly connected with the adjusting nut; the ejector rod is in threaded connection with the adjusting nut and the punching and pulling device; and an ejecting tip of the ejector rod is arranged in at a middle cavity between the two semi-circular wedges. The extractor for the part of the blind hole has following beneficial effects: the extractor is simple in structure and convenient in operation and is time-saving and labor-saving; a pulled-out bearing and a seat thereof are not damaged.
Description
Technical field
The utility model relates to a kind of blind-hole parts extractor, belongs to flight-line maintenance technical field.
Background technology
?when flight-line maintenance or assembling; often can be because the parts such as the part in blind hole and casing coordinate tighter; cause part in blind hole dismounting difficulty, so that cannot pull down part and this part is damaged, this can increase undoubtedly workman labour intensity, incur loss through delay the duration and cause damage.
Summary of the invention
The purpose of this utility model is just to provide a kind of blind-hole parts extractor, for addressing the above problem.
The technical solution of the utility model is: a kind of blind-hole parts extractor, comprise semicircle wedge, elastic ring, gland, adjusting nut, push rod, device and screw are drawn in punching, two semicircle wedge position symmetries that structure is identical, the left side of semicircle wedge is provided with circular cone claw, on the right-hand member periphery of semicircle wedge, elastic ring is set, screw is successively through after the mounting hole on gland and semicircle wedge lug, be connected with adjusting nut engage thread again, and gland and adjusting nut are fixed together, push rod draws device to be connected with adjusting nut and punching respectively threadably, in two semicircle wedge middle cavities, the top of push rod is set.
The beneficial effects of the utility model are: simple in structure, easy to use, time saving and energy saving, be pulled out bearing and bearing is injury-free.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
The specific embodiment
Known with reference to accompanying drawing 1, a kind of blind-hole parts extractor, comprise semicircle wedge 1, elastic ring 2, gland 3, adjusting nut 4, push rod 5, device 6 and screw 7 are drawn in punching, two semicircle wedge 1 position symmetries that structure is identical, the left side of semicircle wedge 1 is provided with circular cone claw, on the right-hand member periphery of semicircle wedge 1, elastic ring 2 is set, screw 7 is successively through after the mounting hole on gland 3 and semicircle wedge 1 lug, be connected with adjusting nut 4 engage thread again, and gland 3 and adjusting nut 4 are fixed together, push rod 5 draws device 6 to be connected with adjusting nut 4 and punching respectively threadably, in two semicircle wedge 1 middle cavities, the top of push rod 5 is set.During operation, first two identical semicircle wedges 1 of structure are closed up and are injected the inner ring of blind-hole parts, then operator one holds adjusting nut 4, another hand-screw turns punching and draws device 6, now push rod 5 is moved to the left, continue rotation punching and draw device 6, push rod 5 top backs down two and semicircle wedge 1 together, circular cone claw on semicircle wedge 1 is extend on the medial surface of part 8 to be torn open, and hook part 8 to be torn open, when two circular cone claws on two semicircle wedges 1 are opened maximum, part 8 to be torn open has been pulled out from the blind hole of bearing 9, now available spanner reversion push rod 5, push rod 5 is moved to right, its top semicircle wedge 1 that exits, contraction due to elastic ring 2, two semicircle wedges 1 automatically close up and throw off with part 8, the dismantlement work of part 8 finishes.
