The right-hand member of the first feed screw as referred to herein is the one end near motor, and the left end of the first feed screw is the one end away from motor.
Operation principle of the present utility model is: during use, is put by large diameter pipe fitting on the table, and the endoporus of pipe fitting is placed on outside two arc locating pieces.Start motor, by the screw pair that feed screw is formed, the rotary motion of motor is transformed to the rectilinear movement of guide rod, second guide rod is subject to the impact of the first guide rod and the first guide rod to move equidistance simultaneously, first guide rod and the second guide rod do opposite linear motion, drive two arc locating pieces on the first guide rod and the second guide rod in slideway, do opposite linear motion.By the time, after arc locating piece pushes against pipe fitting inner wall completely, complete the location clamping of pipe fitting, read the scale on scale, the internal diameter of pipe fitting can be drawn.When getting pipe fitting, only need to reversely rotate motor, arc locating piece will relative motion, away from pipe fitting inner wall towards the motion of pipe fitting circle centre position, now easily can take out pipe fitting.
Compared with prior art, the beneficial effects of the utility model: 1. select motor to carry out self-centering, avoid manually-operated time waste, effectively saved the production time.2. the lower end of the first guide rod and the second guide rod is respectively equipped with two slides, and two slides are connected with the first feed screw and the second feed screw respectively, increases the stability of movement.3. workbench is provided with slideway, and the side of slideway is provided with isometric scale, and the convenient internal diameter size reading pipe fitting, accurate positioning, conveniently carries out respective operations.4. be provided with two symmetrical arc locating pieces in slideway, two arc locating pieces are fixedly connected with the first guide rod and the second guide rod respectively, conveniently push against pipe fitting inner wall.5. workbench is vertical with the second guide rod with the first guide rod, facilitates large diameter pipe fitting directly to place on the table, firmly simple to operate.
Further, described arc locating piece is provided with flexible positioning sleeve, avoids the scuffing to pipe fitting inner wall.
Further, described slideway is positioned on the center line of workbench, and slideway is symmetrical rectangle square hole, and the width of slideway and the width of arc locating piece match, and are convenient to the side-to-side movement in slideway of arc locating piece.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is further described:
Fig. 1 is the structural representation of the utility model for the self-centering unit embodiment of large diameter pipe fitting;
Reference numeral in Figure of description is motor 1, first guide rod 2, second guide rod 3, first feed screw 4, second feed screw 5, first shaft coupling 6, second shaft coupling 7, arc locating piece 8, slideway 9, workbench 10, scale 11.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is further illustrated, but not as to restriction of the present utility model.
As shown in Figure 1, a kind of self-centering unit for large diameter pipe fitting, comprise support, motor 1, the first feed screw 4 be connected with motor 1 by the second shaft coupling 7, second feed screw 5 parallel with the first feed screw 4, first shaft coupling 6 at first feed screw about 4 two ends that are threaded, also comprises the first guide rod 2, second guide rod 3, the workbench 10 vertical with the second guide rod 3 with the first guide rod 2; The lower end of the first guide rod 2 and the second guide rod 3 is welded with two slides respectively, two slides are threaded with the first feed screw 4 and the second feed screw 5 respectively, workbench 10 has slideway 9, workbench 10 outside slideway 9 there is isometric scale 11 with sticking double faced adhesive tape, be provided with two symmetrical arc locating piece 8, two arc locating pieces 8 in slideway 9 and be welded on the first guide rod 2 and the second guide rod 3 respectively.
