Description
Technical field
This utility model relates to extracting tool field, specifically, is that a kind of magnetic draws horse.
Background technology
Drawing horse is for bearing or axle sleeve are pulled up the instrument taken off from axle, simultaneously can be used for by being placed on the object pull-out inside hole in interference fit, existing draw horse substantially can reach use requirement, the pulling capacity i.e. providing the biggest will be drawn thing to pull out, such as a kind of hydraulic screw extractor that number of patent application is 201520296087.1, it is adapted to narrow and small working region, and provides pulling capacity by hydraulic system, but have the disadvantage in that
1, the screw mandrel lower surface drawing horse is little with the frictional force of apical axis contact surface, easily skids, and applies La Mayi run-off the straight during pulling capacity, causes the uniformly run-off the straight of pulled object forced section, damages contact surface.
2, the when of drawing horse to position, the position relationship between leading screw and apical axis is difficult to be transferred to upright position, causes the pulling capacity direction of applying to bias.
Utility model content
The purpose of this utility model be to provide be fixedly connected with to magnetize screw mandrel and can regulate magnetic size permanent magnet seat draw horse, between screw mandrel and apical axis contact surface apply a suction-combining force, increasing friction force more, and facilitate screw mandrel to position.
This utility model is achieved through the following technical solutions: a kind of magnetic draws horse, offer, including center, screw mandrel that the pulling seat of internal thread through hole coordinates with pulling seat center internal thread through hole and be hinged on transporting persons or goods by cart in pulling seat circumference, described screw mandrel upper surface is provided with magnetics, is provided with boosting-rod between screw mandrel upper surface and pulling seat.
Connection between above-mentioned screw mandrel and pulling seat is for threadeding, to the axial force of nut as the pulling capacity drawing horse when being rotated by screw mandrel.During work, adjust the angle between the connection member on transporting persons or goods by cart, the pulling claw of end of transporting persons or goods by cart is gripped in the lower surface of bearing, screw mandrel is square with the axis and screw mandrel lower surface contacts with axial end, utilizing boosting-rod rotary screw rod, screw mandrel changes relative to pulling seat, the position transported persons or goods by cart, due to pulling seat, transports persons or goods by cart and fixes relative to the position of bearing, so screw mandrel changes relative to the axial location of bearing, bearing then changes relative to the axial location of axle.
Above-mentioned transport persons or goods by cart be evenly distributed on pulling seat axially on, in order to draw horse pulling capacity to be uniformly applied in pulled object.
Further, described magnetics is permanent magnet seat, it is provided that bigger absorption affinity.
Further, described permanent magnet seat includes that side opening is provided with the magnetic box of via and is arranged on magnetic box center and rotating permanent magnet, and fixes, through via, the swing handle being connected with permanent magnet.
Further, the direction of described permanent magnet magnetic pole is vertical with the direction of via.
Further, described permanent magnet is cylindrical or bar shaped.
Permanent magnet within above-mentioned permanent magnet seat rotates with the rotation of swing handle, when the two poles of the earth of permanent magnet forward just position to screw mandrel to, and magnetic is the strongest, and screw mandrel is magnetized；When the mid portion brick cutter just position to screw mandrel of permanent magnet, magnetic is the most weak, and screw mandrel demagnetizes.Above-mentioned principle is: bar magnet or the cylinder-shaped magnet magnetic at position, the two poles of the earth are better than far away the magnetic of middle part.
Further, described screw mandrel is the screw mandrel being made up of soft magnetic materials, and pulling seat is the pulling seat being made up of exhausted magnetic material, transports persons or goods by cart as transporting persons or goods by cart of being made up of exhausted magnetic material.Use said structure, after screw mandrel is magnetized, transports persons or goods by cart and pulling seat will not adsorb on screw mandrel.
Further, the lower surface of described screw mandrel is flank, uses said structure, adds the frictional force between screw mandrel and pulled object institute sleeve.
This utility model compared with prior art, has the following advantages and beneficial effect:
(1) in this utility model, adding a magnetic adsorptive power more, and then add the frictional force between screw mandrel and axle between the axle that screw mandrel and pulled object are overlapped, screw mandrel and axle contact surface are not likely to produce relative movement, improve practicality and the safety drawing horse；
(2), in this utility model, after magnetizing due to screw mandrel, there is magneticaction so that screw mandrel lower surface overlaps with the contact plane of axle, so that La Ma is vertical with axial plane, facilitates screw mandrel to position with this so that the operation drawing horse is easier；
(3) in this utility model, on screw mandrel, the place between permanent magnet seat and pulling seat is provided with extension bar, facilitates user to apply torque rotation screw mandrel with this so that the operation drawing horse is easier；
(4) in this utility model, the lower surface of screw mandrel is provided with screw thread plane, and during use, the frictional force between the axle that increase screw mandrel and pulled object are overlapped, screw mandrel and axle contact surface are not likely to produce relative movement, improve practicality and safety.
