Detailed Description
In order to make the technical solution of the present invention better understood by those skilled in the art, the following description is further provided with the technical solution of the present invention for an assembly assisting tool for quick installation of a hard stop ring, in combination with the drawings of the specification and by means of the specific embodiments.
As shown in fig. 1 and 2, an assembly auxiliary tool for quickly mounting a rigid retainer ring comprises a pressing sleeve 1 and a guide post 2, wherein a through hole is formed in the middle of the pressing sleeve 1, and the through hole is a conical hole; the guide post 2 is of a round table structure, and a stepped hole is formed in the middle of the guide post; the retaining ring 3 is sleeved outside the guide post 2, the guide post 2 is inserted into the through hole, and the large-diameter end of the stepped hole is sleeved outside the pipe fitting 4.
The taper of the through hole is the same as that of the outer wall of the guide post 2, so that the retainer ring is stably, quickly and smoothly pushed into the retainer ring assembly groove of the outer wall of the pipe fitting by utilizing the pressing sleeve plane.
The guide post 2 is gradually reduced in diameter from the open end to the closed end.
The aperture of the big hole end of the stepped hole is matched with the outer diameter of the pipe fitting 4, and the aperture of the small hole end is smaller than the outer diameter of the pipe fitting 4.
The hole depth of the big hole end of the stepped hole is equal to the vertical distance from the end face of the pipe fitting 4 to the center of the retainer ring assembling groove, so that the retainer rings can be smoothly assembled in the retainer ring assembling grooves at the two ends of the pipe fitting.
Guide post 2 and through-hole clearance fit, and the clearance size can hold retaining ring 3.
The utility model discloses a use method:
the rigid retainer ring 3 is sleeved from the small-diameter end of the guide post 2, the opening end of the guide post 2 is horizontally sleeved at the port of the pipe fitting 4, the large-diameter end of the through hole of the pressing sleeve 1 is horizontally sleeved at the small-diameter end of the guide post 2, and the rigid retainer ring 3 is pressed into a retainer ring assembling groove formed in the outer wall of the pipe fitting 4 by utilizing the plane of the pressing sleeve 1. And after the assembly of one end is finished, the assembly auxiliary tool is taken down, and the rigid retainer ring 3 at the other end is assembled.
The utility model discloses use the pipe fitting excircle to assemble in pipe fitting one side excircle as the guide pillar assembly benchmark, the distance of guide pillar tang is pipe fitting terminal surface to recess center distance, overlaps the retaining ring on the guide pillar, utilizes to press the cover plane to push the pipe fitting recess with the retaining ring. The invention develops an auxiliary tool for assembling the rigid retainer rings at the two ends of the pipe fitting, solves the problem of scratching of the surfaces of the two ends of the pipe fitting caused by the assembly of the rigid retainer rings, is convenient to operate, only lasts for 30 seconds when the retainer rings at the two ends are pressed in, and improves the assembly efficiency.
