Detailed implementation mode

[0024] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0025] An embodiment of the present invention discloses a feeding fixture for cold-rolled precision seamless steel pipes.

[0026] The present invention provides a cold-rolled precision seamless steel pipe feeding fixture as shown in Figures 1-3 Figure 1, which includes a horizontal plate 1. A support frame 2 is fixedly arranged at the top of the horizontal plate 1. A lifting ring 3 is fixedly arranged at the top of the support frame 2. Cross bars 4 are fixedly arranged at both ends inside the horizontal plate 1. A first clamping plate 5 and a second clamping plate 6 are respectively rotatably sleeved on the rod walls of the two cross bars 4. A rotating groove for the second clamping plate 6 to pass through is formed inside the first clamping plate 5. Receiving grooves are formed at the bottoms of the first clamping plate 5 and the second clamping plate 6. First extension plates 7 and second extension plates 8 are respectively slidably inserted into the two receiving grooves. A pushing frame 9 is slidably sleeved outside the support frame 2. The two ends of the bottom of the pushing frame 9 are respectively in contact and cooperation with the outer walls of the first clamping plate 5 and the second clamping plate 6. Adsorption magnets 15 are fixedly arranged on the sides of the first clamping plate 5 and the second clamping plate 6 close to each other. Torsion springs 14 are sleeved on the rod walls of the two cross bars 4. The torsion springs 14 are respectively fixedly connected to the cross bars 4 and the first clamping plate 5.

[0027] Before processing the steel pipe, connect the lifting ring 3 to the steel cable of equipment such as a gantry crane, move the fixture above the stacked steel pipes, and make the first clamping plate 5 and the second clamping plate 6 arranged on both sides of the steel pipe. Then, the pushing frame 9 moves downward along the side of the support frame 2, so that the bottom of the pushing frame 9 pushes the first clamping plate 5 and the second clamping plate 6. At this time, the first clamping plate 5 and the second clamping plate 6 rotate along the cross bar 4 and are clamped on the outside of the steel pipe, and the steel pipe is magnetically adsorbed by the adsorption magnet 15, which can improve the clamping stability of the steel pipe during the clamping and transportation process. When the steel pipe moves to the designated position, move the pushing frame 9 in the reverse direction, and through the torsion return of the torsion spring 14, the first clamping plate 5 and the second clamping plate 6 are separated from the steel pipe to complete the clamping work of the steel pipe.

[0028] In order to enable the pushing frame 9 to move stably longitudinally, as shown in Figure 1As shown in the figure, a pushing and clamping mechanism for driving the longitudinal movement of the pushing frame 9 is provided inside the pushing frame 9. The pushing and clamping mechanism includes a driving screw 10. The driving screw 10 is rotatably connected to the top of the cross plate 1 and is threaded inside the pushing frame 9. A rotating block 11 is fixedly provided at the top of the driving screw 10.

[0029] When it is necessary to drive the pushing frame 9, the rotating block 11 can be pushed, so that the rotating block 11 drives the driving screw 10 to rotate, and the pushing frame 9 can move longitudinally under the sliding limit of the support frame 4, which is convenient for pushing the first clamping plate 5 and the second clamping plate 6 to complete the clamping work.

[0030] In order to improve the clamping range of the steel pipe, as Figures 1-2 shown, a plurality of spaced threaded holes 12 are provided inside both the first extension plate 7 and the second extension plate 8. Positioning bolts 13 are threaded through the lower ends of the sides of the first clamping plate 5 and the second clamping plate 6 close to each other. The positioning bolts 13 are in threaded cooperation with the threaded holes 12.

[0031] The first extension plate 7 and the second extension plate 8 can slide inside the first clamping plate 5 and the second clamping plate 5, and the positions of the first extension plate 7 and the second extension plate 8 are determined through the cooperation of the positioning bolts 13 and the threaded holes. At this time, the clamping range of the first clamping plate 5 and the second clamping plate 6 can be improved, and seamless steel pipes of various different diameter specifications can be stably clamped, improving the versatility of the fixture.

[0032] Only some exemplary embodiments of the present invention are described by way of illustration above. Undoubtedly, for those of ordinary skill in the art, without departing from the spirit and scope of the present invention, the described embodiments can be modified in various different ways. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the protection scope of the claims of the present invention.
