Technical field
The present invention relates to one and draw horse, especially a kind of bearing draw bench special.
Background technology
Drawing horse is the extracting tool that bearing and axle are separated.During use, with three, transport persons or goods by cart and catch on bearing, then rotate the push rod with screw thread, bearing has just slowly been pulled out axle.Traditional extending range that draws horse is determined by the diameter of a circle at three places of transporting persons or goods by cart, stretch apart from being determined by the length of transporting persons or goods by cart with screw mandrel, samely draw horse poor for the versatility of the objects of different sizes, conventionally need multiple Malaysias of drawing to complete a class job, inefficiency and workload are large.
Summary of the invention
Technical problem to be solved by this invention is: a kind of horse of drawing that can regulate extending range and the degree of depth is provided, and good to the versatility of different parts, operating efficiency is high, workload is little.
For solving the problems of the technologies described above, the technical solution used in the present invention is: one is drawn horse, comprise pulling seat, be arranged on the screw mandrel at pulling seat center, and be distributed on upwards at least three of pulling seat week and transport persons or goods by cart, pulling seat center offers the through hole for wearing screw mandrel, described pulling seat bottom outer rim is provided with circular orientation boss, described in transport persons or goods by cart and comprise detent mechanism, middle part bar and the bottom pulling claw at top, described in the top detent mechanism of transporting persons or goods by cart be flush-mounted on the positioning boss of described pulling seat bottom.
As a kind of optimal way, described in the transport persons or goods by cart detent mechanism at top there is the circular open of an indent, the vertical face of the positioning boss of described pulling seat bottom be ellipse.
As one, further optimize, described pulling seat bottom offers annular groove, is embedded with the range regulation device of transporting persons or goods by cart that is set in pulling seat outside in groove, described in the transport persons or goods by cart concave shaped detent mechanism at top can be flush-mounted in and transport persons or goods by cart in range regulation device.
As a kind of optimal way, described in the transport persons or goods by cart vertical face of range regulation device be I-shaped, by the vertical hollow cylinder at middle part, upper and lower two hollow anchor rings are connected and composed.
As one, further optimize, described in transport persons or goods by cart projection that the detent mechanism at top also has an evagination be positioned at the top of indent circular open, described projection can be flush-mounted in the space that upper and lower two the hollow anchor rings of the range regulation device of transporting persons or goods by cart form.
As a kind of optimal way, described in the range regulation device of transporting persons or goods by cart be to be formed by the vertical hollow cylinder of bottom and a hollow anchor ring on top.
As one, further optimize, the detent mechanism at the described top of transporting persons or goods by cart also has an indent square aperture and is positioned at the top of indent circular open, described in the transport persons or goods by cart hollow anchor ring of range regulation device can be flush-mounted in the indent square aperture of the top detent mechanism of transporting persons or goods by cart.
The invention has the beneficial effects as follows: because the present invention is provided with positioning boss, the range regulation of the transporting persons or goods by cart device of the top detent mechanism of transporting persons or goods by cart, pulling seat bottom, make to transport persons or goods by cart and can rotate to an angle with respect to pulling seat, the extending range of the bottom pulling claw of therefore transporting persons or goods by cart can regulate, widen the scope of application of drawing horse, improved the operating efficiency of drawing horse.
