Detailed Description

As shown in fig. 1-7, a one-step method clamping and centering device for a working tube of a heat preservation tube comprises a chuck body 1, a guide rail 2, a plurality of sliding blocks 3, a clamping disc 4, a clamping assembly 5, a rotating shaft 6 and a rotating disc 7; as shown in fig. 2, a central hole 101 is arranged in the center of the chuck body 1, a hexagonal groove 102 is concentrically arranged outside the central hole 101, and a guide rail 2 is arranged in the groove 102; as shown in fig. 3 and 4, the guide rail 2 is formed by abutting six single rails end to end, and the single rails are movably connected with the sliding blocks 3 and correspond to the sliding blocks one by one; as shown in fig. 5, a clamping disc 4 is mounted on the sliding block 3, the clamping disc 4 is formed by splicing a plurality of radially arranged clamping components 5, and a protruding shaft 501 is arranged on each clamping component 5; as shown in fig. 7, notches 701 are formed in positions, corresponding to the protruding shafts 501, of the rotating disc 7 one by one, a through hole 702 matched with the middle hole 101 is formed in the center of the rotating disc 7, a lifting lug 703 is further formed in the rotating disc 7, and the rotating lifting lug 703 pushes the clamping disc 4 to rotate so as to push the sliding block 3 to slide along the guide rail 2, so that centering and clamping operations are achieved.

As shown in FIG. 1, the inner diameters of the middle hole 101 and the through hole 702 are consistent, and the steel pipe fitting is suitable for steel pipes with different specifications and models.

The central axis of the chuck body 1, the central axis of the guide rail 2, the central axis of the clamping disc 4 and the central axis of the rotating disc 7 are overlapped. The uneven thickness of the heat preservation layer of the heat preservation pipe caused by the fact that the heat preservation steel pipe shakes leftwards and rightwards in the conveying process and deviates from the center is avoided.

As shown in fig. 5 and 4, four threaded holes 504 are uniformly distributed on the circumference of the protruding shaft 501, and the clamping assembly 5 and the sliding block 3 are screwed into the threaded holes 504 to be connected and fixed. The screw connection is convenient to detach and replace, and meanwhile, the protruding shaft 501 is fixed with the sliding block 3, so that when the rotating disc 7 is rotated, the sliding block 3 can be uniformly stressed and can move on the sliding rail 2.

As shown in fig. 5, two sides of the clamping assembly 5 are respectively provided with a mounting groove 502 and a guide groove 503, two side walls of the mounting groove 502 are provided with threaded holes for fixing the rotating shaft 6, and the rotating shaft 6 is in sliding contact with the guide groove 503 on the adjacent clamping assembly 5.

Specifically, the clamping disc 4 is defined by six clamping assemblies 5, and each clamping assembly 5 can move tangentially along the original clamping disc 4 to change the aperture of the original clamping disc 4 to form a new clamping disc 4. Because the aperture of the clamping disc 4 is adjustable, the aperture of the clamping disc 4 can be adjusted according to the outer diameter of the heat-insulating pipe so as to clamp the heat-insulating pipe. In addition, because the change of the aperture of chucking dish 4 is realized with former chucking dish 4 carries out tangential movement, and constitutes the tight coupling between the chucking subassembly 5 of chucking dish 4, does not have the joint clearance, and the size of the chuck 4 that chucking subassembly 5 formed changes, and the centre of a circle is unchangeable, has further improved the positioning accuracy of the axis after pressing from both sides tightly.

As shown in fig. 6, the rotating shaft 6 includes a spindle 601, a drum 602, a deep groove ball bearing 603 and a shaft stopper 604, the spindle 601 is axially connected in the drum 602 in a penetrating manner, the deep groove ball bearing 603 and the shaft stopper 604 are sequentially mounted at both ends of the spindle 601, and threaded holes for connecting with the mounting groove 502 are formed in end faces at both sides of the spindle 601.

Specifically, the diameter and the mounting groove 502 adaptation of cylinder 602, and cylinder 602 and guide way 503 closely laminate, and deep groove ball bearing 603 is used for the location to avoid the rotatory back-and-forth movement in the same time of cylinder, and axle bumper 604 effectively fixes deep groove ball bearing 603 to prevent in cylinder 602 course of operation, the not hard up phenomenon of deep groove ball bearing 603 appears, and then influences the work efficiency of cylinder.

The using process of the invention is as follows:

referring to fig. 1, in the first embodiment of the present invention, at least two sets of chuck plates 1 are respectively installed and fixed on a frame of a thermal insulation pipe conveying line, the thermal insulation pipe passes through a through hole 702 of a rotating plate 7, a clamping plate 4 and a central hole 101 of the chuck plate 1, and the clamping plate 4 can ensure that the central line position of the thermal insulation pipe is unchanged during the linear motion of the thermal insulation pipe.

According to the second embodiment of the invention, when the pipe diameter of the heat-insulating pipe changes, the lifting lug 703 on the rotating disc 7 is rotated clockwise to open the clamping disc 4 to the maximum, the circle center is unchanged, the heat-insulating pipe passes through the through hole 702 of the rotating disc 7, the clamping disc 4 and the central hole 101 of the chuck body 1, and then the lifting lug 703 is rotated anticlockwise to clamp the heat-insulating pipe, so that the heat-insulating pipes with different pipe diameters can be met, and meanwhile, the central axis of the heat-insulating pipe cannot be displaced in the conveying process.

The above-described embodiments are merely illustrative of the preferred embodiments of the present invention, and do not limit the scope of the present invention, and various modifications and improvements of the technical solution of the present invention can be made by those skilled in the art without departing from the spirit of the present invention, and the scope of the present invention is defined by the claims.
