Abstract
The invention discloses two pawls and draw horse, traditional horse of drawing easily is drawn bad bearing, inefficiency, is sometimes not suitable for drawing bore bearings when pulling shaft holds, cannot operate especially in the gear-box that space is smaller.There is provided a kind of adjustable, what can operate in gear-box draws horse, and boosting-rod is equipped with on described thread top, and there is supporting seat bottom.Described drag hook upper end is installed on by screw bolt and nut in the locating slot on the arm of force.The screwed hole of thread and the arm of force is connected, and by fixing drag hook, prevents drag hook from horizontally slipping, and the symmetry due to left and right locating slot vertically can stablize pull-out bearing and gear.
Description
Technical field
The invention belongs to mechanical field, be specifically related to a kind of bearing draw bench special.
Background technology
At present, horse is drawn to be the extracting tool that bearing is separated with axle.Catch on bearing with three pawls during use, then rotate the push rod with screw mandrel, bearing has just been drawn out.Traditional horse of drawing easily is drawn bad bearing, inefficiency, is sometimes not suitable for drawing bore bearings when pulling shaft holds, cannot operate especially in the gear-box that space is smaller.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of adjustable, and what can operate in gear-box draws horse.
The technical solution used in the present invention is: a kind ofly draw horse to comprise connecting thread pull bar on drag hook, the arm of force, the described arm of force, and the described arm of force has locating slot, and described drag hook is symmetrical movable in locating slot.Boosting-rod is equipped with on described thread top, and there is supporting seat bottom.Described drag hook upper end is installed on by screw bolt and nut in the locating slot on the arm of force.The screwed hole of thread and the arm of force is connected, the described external screw thread of thread bottom and the screw-internal thread fit of supporting seat.Described locating slot is used for the occasion that different size bearing obtains gear, by fixing drag hook, prevents drag hook from horizontally slipping, and the symmetry due to left and right locating slot vertically can stablize pull-out bearing and gear.The effect of supporting seat is: when drawing gear and bearing, a lot of situation lower support point is uneven, easily causes operating point displacement and drag hook distortion, and design supporting seat can better be dealt with problems.
Beneficial effect of the present invention is: locating slot ensure that the up rightness of drawing work, adapts to different occasion.Supporting seat is installed bottom thread and realizes the activity that supporting seat has positive and negative 10 ° of scopes.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
In Fig. 1,1 drag hook, 2 supporting seats, 3 arm of forces, 4 threads, 5 boosting-rods, 6 nuts, 11 coupler bodies, 12 hook portions.
In Fig. 2,3 arm of forces, 4 threads, 5 boosting-rods, 6 nuts, 7 bolts.
Detailed description of the invention
Below in conjunction with accompanying drawing, the invention will be further described.
One draws horse to comprise drag hook, the arm of force, arm of force connecting thread pull bar, and the arm of force has locating slot, and drag hook symmetry is arranged in locating slot, and there is boosting-rod on thread top, and there is supporting seat bottom.Described locating slot, for the occasion of vary in size bearing and gear, by fixing drag hook, can prevent drag hook from horizontally slipping, can pull out bearing and gear timely.The effect of supporting seat is: cross very much situation lower support point when drawing bearing and gear uneven, easily cause work to think and distortion, better can solve problems after being designed with supporting seat.
Claims (3)
1. two pawls draw horse to comprise, drag hook (1), supporting seat (2), the arm of force (3), thread (4), boosting-rod (5), nut (6), bolt (7), locating slot (8), coupler body (11), hook portion (12).
2. two pawls according to claim draw horse, it is characterized in that: drag hook 1 is installed in by bolt 7 in the locating slot 8 on the arm of force 3.
3. two pawls according to claim 1 and 2 draw horse, it is characterized in that: thread is connected with the arm of force, thread bottom and supporting seat screw-internal thread fit.
