Detailed description of the invention
Below in conjunction with embodiment, the utility model is described further.
As shown in Figure 1, Figure 2 and Figure 3, the utility model is provided with leading screw 1, rocking bar 12, body frame 5, support 15 and draws leg 14, and rocking bar 12 is located in the circular hole on leading screw 1 top, and the two ends pier of rocking bar 12 is flat; The bottom of leading screw 1 is located in the circular hole in the middle of body frame 5, and the bottom of leading screw 1 is embedded in the circular hole of support 15 upper end, is connected the bottom of leading screw 1 by elastic opening pin 9 with support 15 upper end; Be welded with cylinder clamping leg 11 in the middle of the bottom of support 15, body frame 5 is welded with short handle and nigger; All be connected with and draw leg 14 by big hexagon head bolt 6, the large tight split nut 7 of hexagonal, plain washer 8 at the two ends of body frame 5, be connected with screw 2 at body frame 5 by little hexagon-headed bolt 4, the tight split nut 13 of little hexagonal, between screw 2 and body frame 5, be provided with little spring 3; Screw 2 lower end is provided with screw thread, and screw 2 is connected by screw thread with leading screw 1.
The centre of leg 14 is drawn to be respectively equipped with rectangular shaped slot at two, leg 14 is drawn to be connected with support 15 by the big hexagon head bolt 6 on rectangular shaped slot, the large tight split nut 7 of hexagonal, plain washer 8, draw on the big hexagon head bolt 6 in leg 14 rectangular shaped slot and have roller 10, roller 10 is embedded in the rectangular shaped slot that draws in the middle of leg 14; The bottom of leg 14 is drawn to be welded with cylinder clamping leg 11 respectively at two, round thread hole is provided with at the right-hand member of cylinder clamping leg 11, dovetail jackscrew 17 and cylinder are clamped leg 11 and are connected by this screwed hole, clamp between leg 11 be also provided with plain washer 8 and big spring 16 at dovetail jackscrew 17 and cylinder.
Be provided with trapezoidal thread on the left of screw 2, the excircle of leading screw 1 is also provided with trapezoidal thread, and screw 2 and leading screw 1 are connected together by trapezoidal thread.Two draw leg 14 and support 15 clamp cylinders workpiece 18 after finely tune the axiality that three dovetail jackscrews 17 can guarantee two welding cylindrical workpiece 18 again.
Below the course of work of the present utility model is illustrated.
When inwardly pushing away with the teethed end faces that the right hand pins screw 2, being threaded of screw 2 and leading screw 1 will temporary disengagement, and at this moment left hand is held rocking bar 12 and upwards carried, and rocking bar 12 will drive leading screw 1, support 15 rises fast.Meanwhile, support 15 fast rising also drive two to draw leg 14 to open fast.Then required welding cylindrical workpiece 18 is put into immediately below support 15, now only left hand need be unclamped, under gravity, support 15 drives leading screw 1 to decline fast, meanwhile, the quick decline of support 15 also drives two to draw leg 14 to close fast, and then finely tunes leading screw 1, reaches the object of Quick-clamped cylindrical workpiece 18.And then finely tune three dovetail jackscrews 17, guarantee that cylindrical workpiece 18 is coaxial with three dovetail jackscrews 17, ensure the accurate axiality of two cylindrical workpieces 18 thus.
Finally, the inside thruster of teethed end faces of screw 2 is pinned again with the right hand, left hand is held rocking bar 12 and is upwards carried fast, then two cylindrical workpieces 18 are put into immediately below support 15 simultaneously, then two solders side are adjacent to, now unclamp left hand, under gravity, support 15 and two draw leg 14 to clamp two cylindrical workpieces 18 fast, and then finely tune leading screw 1 and just two cylindrical workpieces 18 can have been clamped tightly, also ensure that the axiality of two cylindrical workpieces 18 simultaneously.
Two are drawn leg 14 centre to be provided with rectangle elongated slot, can be changed by rectangular channel and draw the relative position of leg 14 on body frame 5, can change clamping diameter like this, the diameter of holding workpiece can between 34 millimeters to 170 millimeters, and the overall weight of the utility model rapid pipeline welded retainer only has 5 kilograms.
Only as described above; be only specific embodiment of the utility model; when can not limit the scope of the utility model enforcement with this; therefore the displacement of its equivalent assemblies; or the equivalent variations to do according to the utility model scope of patent protection and amendment, all still should belong to the category that the utility model claims are contained.
