Abstract
The utility model relates to a drawing device for blind holes, which comprises a seat and a drawing unit. The seat is provided with a seat plate, a first ejector rod and a second ejector rod, the drawing unit is provided with a screw, a nut, a connecting plate, a first drawing hook, a second drawing hook, a rotary nut, a fixed ejector block and an adjusting and positioning screw, the lower end of the screw mounted in the center of the seat plate is fixed to the connecting plate, the upper ends of the first drawing hook and the second drawing hook are respectively hinged to the left end and the right end of the connecting plate, and the rotary nut and the fixed ejector block are respectively mounted in the middles of the first drawing hook and the second drawing hook. The two symmetrical drawing hooks are hinged to the connecting plate, the rotary nut is mounted on one drawing hook, the fixed ejector block is arranged on the other drawing hook, when the two drawing hooks are hooked to the edge of an outer ring or inner ring of a bearing or hooked to a ball groove, the tail end of the positioning screw mounted on the rotary nut is abutted to the ejector block so as to achieve drawing in such manner that the two drawing hooks are not separated from a bearing ring, and the drawing device has the advantages of wide application range, even stress, easiness in drawing and flexibility in operation.
Description
Technical field
The utility model belongs to the repair of machine technical field of tools, but relate to a kind of not only can hook bearer ring edge but also the blind hole drawing device of hook bearer ring pearl groove.
Background technology
In repair of machine, because of broken its outer race of ball bearing pearl is stayed on the housing, or after the axle taking-up, bearing is stayed on the housing, for staying outer annular distance of housing upper ball bearing or interior annular distance, be called blind hole on the industry, take out outer race or the bearing stayed on the housing, existing way is to adopt mounting and cam to draw to dial device, is hooked in a side on the bearing edge with the screw mandrel end cams, and screw mandrel puts the protruding cover location of protruding toward another side, rotate screw, and pull out bearer ring, and there is following drawback in it: the one, only draw the annular distance of dialling 20-50mm, narrow application range; The 2nd, only to draw on one side, discontinuity is difficult for pulling out; The 3rd, can only the draw ring edge, can not the bead pilot trench.
The utility model content
In order to overcome the above-mentioned shortcoming of prior art, the utility model provide a kind of scope of application big, stressed evenly, pull out easily, but not only can hook bearer ring edge but also the blind hole drawing device of hook bearer ring pearl groove.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of blind hole drawing device, comprise mounting and draw group device, mounting has seat board, push rod one and push rod two, draw and dial device screw mandrel, screw, connecting plate, drag hook one, drag hook two, rotation nut, fixedly jacking block and adjusting positioning screw are arranged, the screw mandrel bottom that is installed in the seat board center is fixed on the connecting plate, the upper end of drag hook one and drag hook two is hinged on respectively about connecting plate on the end, and rotation nut and fixing jacking block are housed respectively at drag hook one and drag hook two middle parts.
Screw mandrel and connecting plate constitute inverted T-shape.
Be installed in the adjusting positioning screw of rotation in the nut, the tail end of regulating positioning screw is pressed in fixedly on the tubaeform cave of jacking block.
Described drag hook one and drag hook two are installed in the both sides of seat board symmetrically.
The beneficial effects of the utility model are: adopt 2 symmetrical drag hooks that are hinged on the connecting plate, and on a drag hook, the rotation nut is installed, fixing jacking block on another drag hook, when 2 drag hooks are hooked on outer race or the interior ring edge or on the pearl groove time, hold out against on jacking block with the positioning screw tail end that is contained on the rotation nut, the mode that makes 2 drag hooks can not break away from bearer ring reaches the purpose of pulling out, and has the advantage that the scope of application is big, stressed evenly, pull out easy and flexible operation.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Among the figure: 1-seat board, 2-push rod one, 3-push rod two, 4-screw mandrel, 5-screw, 6-connecting plate, 7-drag hook one, 8-drag hook two, 9-rotate nut, fixedly jacking block, 11-regulate positioning screw to 10-.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
Referring to Fig. 1, a kind of blind hole drawing device, comprise mounting and draw group device, mounting has seat board 1, push rod 1 and push rod 23, draw and dial device screw mandrel 4, screw 5, connecting plate 6, drag hook 1, drag hook 28, rotation nut 9, fixedly jacking block 10 and adjusting positioning screw 11 are arranged, screw mandrel 4 bottoms that are installed in seat board 1 center are fixed on the connecting plate 6, screw mandrel 4 constitutes inverted T-shape with connecting plate 6, the upper end of drag hook 1 and drag hook 28 is hinged on respectively on connecting plate about 6 end, and rotation nut 9 and fixing jacking block 10 are housed respectively at drag hook 1 and drag hook 28 middle parts; Be installed in the adjusting positioning screw 11 of rotation in the nut 9, the tail end of regulating positioning screw 11 is pressed in fixedly on the jacking block 10 tubaeform caves.
The utility model adopts 2 symmetrical drag hooks that are hinged on the connecting plate, and on a drag hook, the rotation nut is installed, fixing jacking block on another drag hook, when 2 drag hooks are hooked on outer race or the interior ring edge or on the pearl groove time, hold out against on jacking block with the positioning screw tail end that is contained on the rotation nut, the mode that makes 2 drag hooks can not break away from bearer ring reaches the purpose of pulling out.
Characteristics of the present utility model: the one, the scope of application is big, and diameter can both be pulled out at the bearer ring of 30-160mm; The 2nd, stressed even, pull out easily; The 3rd, can be hooked on the bearer ring edge or be hooked on the bearer ring pearl groove, decide flexible operation on convenient.
