Description
Technical field
The utility model relates to a kind of steel pipe special fixture, especially a kind of rectangular steel pipe intersection cutting self-centering fixture.
Background technology
At present, intersection-line cutting machine, in the time that steel pipe is cut, must adopt chuck clamping steel pipe, and in cutting process, chuck drives steel pipe around the rotation of chuck axis, and for pipe, general employing three is grabbed or four grabbed self-centering chuck.But will clamp rectangular steel pipe time, cannot adopt three to grab self-centering chuck, and self-centering four grab chuck and can only carry out self-centering clamping by square shaped steel pipe, can only adopt four of non-automatic centering to grab chuck for rectangular tube, in pipe fitting clamping process, with regard to requiring a great deal of time, artificial centering be carried out in the center of rectangular tube like this.In order to make pipe intersecting lines cutting equipment and the rectangular tube intersection cutting equipment can be general, need on the basis of existing pipe self-centering chuck, design and a set ofly can make the self-centering fixture of rectangular steel pipe, so just can make the user of pipe intersecting lines cutting equipment in the time having rectangular steel pipe intersection cutting demand, not need to order for rectangular steel pipe intersection cutting equipment specially again.
Utility model content
In order to overcome the deficiency of above-mentioned existing product, the purpose of this utility model is to provide a kind of rectangular steel pipe intersection cutting self-centering fixture, this fixture can be clamped in three and grab or four grab on self-centering chuck, fixture itself is concentric with chuck, fixture, can be to rectangular steel pipe self-centering in the time that rectangular steel pipe is clamped simultaneously.
In order to realize the technical scheme that the purpose of this utility model adopts be: a kind of rectangular steel pipe intersection cutting self-centering fixture, is characterized in that: it is made up of pressing plate, intermediate membrane, centration axis, connecting plate, double end screw mandrel, upper flange, lower wing plate, deep groove ball bearing, deep groove ball bearing seat, feed screw nut, thrust bearing, thrust shaft block; The positive and negative both sides of described intermediate membrane are welded with respectively a pair of upper flange and lower wing plate; Described upper flange two ends are provided with thrust shaft block installing hole; Described lower wing plate two ends are provided with deep groove ball bearing seat installing hole; Described deep groove ball bearing is arranged in deep groove ball bearing seat; Described thrust bearing is arranged in thrust shaft block; Described double end screw mandrel two ends coordinate with thrust bearing and deep groove ball bearing respectively, and both sides motion thread part is equipped with feed screw nut.
The beneficial effects of the utility model are: the appurtenances that can be used as pipe intersecting line cutter, in the time that needs carry out rectangular steel pipe cutting, can directly clamp this fixture with the self-centering chuck of intersection-line cutting machine, this fixture rotates around chuck axis, this fixture can carry out self-centering clamping to the rectangular steel pipe of clamping simultaneously, has solved the self-centering clamping problem of rectangular steel pipe.

Detailed description of the invention
In the first embodiment shown in Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, Fig. 6, a kind of rectangular steel pipe intersection cutting self-centering fixture, is characterized in that: it is made up of pressing plate, intermediate membrane, centration axis, connecting plate, double end screw mandrel, upper flange, lower wing plate, deep groove ball bearing, deep groove ball bearing seat, feed screw nut, thrust bearing, thrust shaft block; The positive and negative both sides of described intermediate membrane are welded with respectively a pair of upper flange and lower wing plate; Described upper flange two ends are provided with thrust shaft block installing hole; Described lower wing plate two ends are provided with deep groove ball bearing seat installing hole; Described deep groove ball bearing is arranged in deep groove ball bearing seat; Described thrust bearing is arranged in thrust shaft block; Described double end screw mandrel two ends coordinate with thrust bearing and deep groove ball bearing respectively, and both sides motion thread part is equipped with feed screw nut.
In the second embodiment shown in Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, Fig. 6, described centration axis adopts welding manner to be connected with connecting plate, concentric with two pairs of pressing plates; Described connecting plate is welded on intermediate membrane middle part; The distribution that is orthogonal of described upper flange and lower wing plate; Described deep groove ball bearing seat is welded in installing hole; Described thrust bearing is welded in installing hole; The rotation direction of described double end screw mandrel two ends motion thread is contrary, adopt articulation hole to be connected with bolt with pressing plate, and connecting portion has certain adjusting play, while ensureing to rotate every double end screw mandrel separately, corresponding one end of the pressing plate that two ends are all connected with feed screw nut respectively can freely be moved along bipitch silk rod axis.
Use when the utility model, centration axis is clamped in three grabs or four grabs on self-centering chuck, and when chuck rotation, this fixture rotates around chuck axis; The double end screw mandrel of manual rotation central dividing plate both sides, because the rotation direction of screw mandrel both sides screw thread is contrary, in screw mandrel rotary course, respective nut drives the pressing plate that is attached thereto just along screw mandrel axis in the same way or counter motion, reaches self-centering function; When clamping rectangular steel pipe, the double end screw mandrel of rotation central dividing plate both sides, makes corresponding pressing plate difference clamp rectangular steel pipe up and down and the left and right sides; In the time that the pressing plate of intermediate membrane both sides and feed screw nut are installed, need to adjust the concentricity of two pairs of pressing plates and centration axis, concentric with centration axis to ensure pressing plate rectangular steel pipe center when the clamp rectangular steel pipe.
