Abstract
A mechanical large-torsional moment spanner belongs to the tie-down device which is used in the situation which needs much big preloading torque. The utility model is characterized in that a force-application gear column cooperates with spanner-seat, a jack of radial force-application rod is installed on the force-application gear; a fastener or a patching-tenon of a jacket is located at the base frame of the spanner-seat, and a thread-hole which cooperates with force-regulative nut is installed at the upper side; a force-application gear column which radial-section presents inverted T-shape is installed in the spanner-seat bore, the force-regulative nut is equipped on the force-application gear column and cooperates with the bore-thread in spanner-seat, an elastic element is installed between force-regulative nut and the T-shaped end-face of force-application gear column; radial pitch face-gear is equipped on the down-end-face of force-application gear column and the junction surface of spanner-seat. The utility model adopts mechanical type with simple structure, reliable work, low cost and large tightening torque. The utility model is suitable for the places where use electromotion and pneumatic tool not to get there.
Description
Technical field
The utility model relates to a kind of utensil to the fastening usefulness of securing member, is specially mechanical type high pulling torque spanner.
Background technology
Along with improving constantly of the technical merit of China's machinery manufacturing industry, for guaranteeing product quality, many equipment and facility have adopted high-strength bolt increasingly extensively, and the fastening pre-fastening moment of bolt proposed strict requirement, the heavy duty equipment that especially bears the vibration of heavy load and intense impact is just even more important.For quality and the reliability that improves thread connection, accurately control the pre-fastening moment that high-strength bolt connects, released the torque wrench of various patterns on the market.By investigating, find that the less intelligent degree of torque wrench of moment on the market is higher, use more extensively, use also easily, but cost is higher; The spanner that moment is bigger is then unsatisfactory, or very heavy, or cost is higher, or screw-down torque indefinite (excessive or too small).
Summary of the invention
In order to overcome the shortcoming that above-mentioned prior art exists, the purpose of this utility model provides a kind of mechanical type high pulling torque spanner, and pre-fastening moment is big, and cost is low, and is simple in structure, easy and simple to handle.
The technical solution of the utility model is, this mechanical type high pulling torque spanner is characterized in that application of force tooth post matches with the spanner seat, and application of force tooth post is provided with radially force application rod jack; The bottom of described spanner seat is provided with the tenon that patches of securing member or sleeve, and its upper end is provided with the screwed hole that matches with the power nut of accent; The application of force tooth post that radial section is inverted T shape is positioned at spanner seat hole, transfers the power nut sleeve to place on the application of force tooth post and with the spanner seat inner hole thread and cooperates, and is provided with flexible member between accent power nut and application of force tooth post T type end side; Be equipped with intermeshing radial end face tooth on the lower surface of application of force tooth post and the faying face of spanner seat.
Further program of the utility model is, is provided with Anti-rotating grommet between application of force tooth post T type end side and flexible member, and described flexible member is helical spring or disk spring.
Further program of the utility model is that the bottom of spanner seat is provided with the hexagonal tenon that directly cooperates with securing member, perhaps is the square tenon that is connected with sleeve.
Operation principle of the present utility model is, according to the difference of the required moment of securing member, adjust accent power nut to correct position (above scale is arranged), by helical spring (perhaps butterfly spring) pressure is passed to Anti-rotating grommet, make it tightly push down application of force tooth post, to reach required moment requirement.During in the upper end of application of force tooth post, application of force tooth styletable face tooth acts on spanner seat end face tooth by the frictional force between the flank of tooth, reaches the purpose that makes securing member tighten or loosen as moment loading.When moment surpassed the moment of friction of the both ends of the surface between cog that the pressure of helical spring (perhaps butterfly spring) causes, application of force tooth post can be jumped out from teeth groove automatically and skid, and shows that the pre-fastening moment of securing member has reached rated value.
The beneficial effects of the utility model are, adopt mechanical type, and simple in structure, reliable operation, cost is low, pre-fastening moment is big.Be particularly suitable for the place that electronic, pneumatic fastening appliance can't operation.
Description of drawings
Below in conjunction with accompanying drawing the utility model is described in further detail:
Figure is a structural representation of the present utility model.
Among the figure; 1 application of force tooth post, 2 force application rod jacks, 3 transfer power nut, 4 application of force tooth styletable face teeth, 5 to patch tenon, 6 spanner seats, 7 spanner seat end face teeth, 8 Anti-rotating grommets, 9 flexible members.
The specific embodiment
As figure, this mechanical type high pulling torque spanner, application of force tooth post 1 matches with spanner seat 6, and application of force tooth post 1 is provided with radially force application rod jack 2, and force application rod is a circular cylinder.The bottom of spanner seat 6 is provided with securing member or sleeve patches tenon 5, and patching tenon 5 can be the hexagonal tenon that directly cooperates with securing member, perhaps is the square tenon that is connected with sleeve, is being connected with various securing members by sleeve.
Spanner seat 6 upper ends are provided with tapped cylindric application of force tooth post hole, the application of force tooth post 1 that the cross section is inverted T shape is positioned at application of force tooth post hole, accent power nut 3 be placed on the application of force tooth post 1 and with application of force tooth post hole threaded engagement, between accent power nut 3 and application of force tooth post T type end side, be provided with flexible member 9, as spring or dish-shaped sheet, between application of force tooth post T type end side and flexible member, be provided with Anti-rotating grommet 8.The lower surface of application of force tooth post 1 is provided with radially application of force tooth styletable face tooth 4, and spanner seat 6 is provided with radially spanner seat end face tooth 7 with the faying face of application of force tooth styletable face.Spanner seat end face tooth 7 is meshing with each other with application of force tooth styletable face tooth 4.
Difference according to the required moment of securing member, adjust accent power nut 3 to correct position (above scale is arranged), by helical spring (perhaps butterfly spring) pressure is passed to Anti-rotating grommet 8, make its T type end side of tightly pushing down application of force tooth post 1, to reach required moment requirement.During in the upper end of application of force tooth post 1, application of force tooth styletable face tooth 4 acts on spanner seat end face tooth 7 by the frictional force between the flank of tooth, reaches the purpose that makes securing member tighten or loosen as moment loading.When moment surpassed the moment of friction of the both ends of the surface between cog that the pressure of helical spring (perhaps butterfly spring) causes, application of force tooth post can be jumped out from teeth groove automatically and skid, and shows that the pre-fastening moment of securing member has reached requirement.
