Embodiment
Elaborate to embodiments of the invention below, the present embodiment is implemented under premised on technical solution of the present invention, give detailed embodiment and concrete operating process, but protection scope of the present invention is not limited to following embodiment.
As shown in figures 1-4, the end socket 1 of the present embodiment, comprise centralising device 2, be fixed on the back up pad 3 of end socket 1 inside and treat the co-axially fixed axle sleeve 4 with end socket 1, centralising device 2 comprises three groups of detent mechanisms 21, locating sleeve 22, sliding sleeve 23 and pipe core 24; Often organize detent mechanism 21 comprise the first web member 211, second web member 212, the 3rd web member 213, connecting rod 214 and extend claw 215; First web member 211 is fixed on pipe core 24, and the second web member 212 is fixed on sliding sleeve 23, and the 3rd web member 213 is fixed on connecting rod 214, and the first web member 211, second web member 212, the 3rd web member 213 lay respectively on leg-of-mutton three summits; One end of described elongation claw 215 is hinged on the first web member 211, and the other end is unsettled; One end of connecting rod 214 is hinged on the second web member 212, and the other end is hinged with elongation claw 215 by the 3rd web member 213; Described locating sleeve 22 is connected to the bottom of sliding sleeve 23, pipe core 24 is set in sliding sleeve 23, the angle of the adjacent positioned mechanism 21 centrally circumference of pipe 24 is identical, the two ends of back up pad 3 are fixed in end socket 1, axle sleeve 4 is set on locating sleeve 22, and the free end extending claw 215 is positioned on the inside surface of end socket 1.
Elongation claw 215 and connecting rod 214 need to carry out necessary calculating or analogue simulation according to the nominal diameter of end socket 1, set out the most reasonably length.When the nominal diameter change of end socket 1, extend claw 215 adjustment of carrying out necessity all corresponding to connecting rod 214.Elongation claw 215 and connecting rod 214 are flexibly connected; When extending claw 215 or connecting rod 214 needs to change because of the nominal diameter change of damage or end socket 1, changing after can pulling down, adaptability and the flexibility function of this device is provided further.
First web member 211, second web member 212 is identical with the structure of the 3rd web member 213, each web member includes clip 200, bearing pin 201 and in order to spacing circlip 202, described clip 200 is U-shaped, the opening of U-shaped clip 200 is provided with through hole, bearing pin 201 is set on described clip 200, one end of bearing pin 201 is provided with in order to spacing projection, the other end connects circlip 202, stable connection can be guaranteed, be unlikely to come off, such elongation claw 215 can rotate around bearing pin 201, but can not come off; Extend claw 215 end opens through hole, the bearing pin 201 on the first web member 211 is through the through hole on clip 200 and the through hole extending claw 215 end; Extend on claw 215 and offer through hole, the bearing pin 201 on the 3rd web member 213 is through the through hole on the through hole on clip 200 and elongation claw 215; One end of connecting rod 214 is fixed on the clip 200 of the 3rd web member 213, and the other end offers through hole, and bearing pin on the second web member 212 201 is through the through hole of the through hole on clip 200 and connecting rod 214 end, and circlip 202 is for being provided with the annular ring of opening.
The detent mechanism 21 of the present embodiment, locating sleeve 22, sliding sleeve 23 and pipe core 24 are made for stainless steel.Not only ensure that the attractive in appearance of entirety, prevent simultaneously and get rusty, improve the serviceable life of this device.
In other embodiments, the outer all coated chromium coating of detent mechanism 21, locating sleeve 22, sliding sleeve 23 and pipe core 24, also can play antirust effect.
Locating sleeve 22 and sliding sleeve 23 are threaded connection, and guarantee the detachability of locating sleeve 22; When the dimensions change of axle sleeve 4, only need to change locating sleeve 22, make it corresponding with axle sleeve 4; Thus adaptability and the flexibility function of this device can be improved.
During work, be placed on the worktable of central aperture by end socket 1, connecting positioning sleeve 22 and axle sleeve 4, then the entirety of centralising device 2 puts into end socket 1, and now end socket 1 and axle sleeve 4 are not on the same line; The power that applying one is downward on pipe core 24, now, pipe core 24 is slide downward in sliding sleeve 23, drives elongation claw 215 to move simultaneously, elongation claw 215 is moved to the inwall of end socket 1, and drives the center of axle sleeve 4 gradually to end socket 1 close; According to three-point fix principle, when three elongation claws 215 all contact with end socket 1 inside surface and no longer move, axle sleeve 4 on the same line, is welded in back up pad 3, thus ensure that the right alignment of end socket 1 is 0.05 by the axle center of axle sleeve 4 and end socket 1.
When the interior diameter of end socket 1 diminishes due to the reason of tolerance, only need upwards to carry pipe core 24, the inside surface close contact guaranteeing to extend claw 215 and end socket 1 can ensure the right alignment requirement of axle sleeve 4 and end socket 1; When the interior diameter of end socket 1 becomes large due to tolerance reason, only need firmly to pressing down pipe core 24, the inside surface close contact guaranteeing to extend claw 215 and end socket 1 can ensure the right alignment requirement of axle sleeve 4 and end socket 1.
Thus, the situation that the present invention can use diameter to change with tolerance, embodies the principle of flexible design.The present invention can be widely used in location and the welding of orientation, various types of end socket 1 axle center parts.
