[0031] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by technicians in the technical field of this application; the terms used in the specification of the application herein are only for the purpose of describing specific embodiments and are not intended to limit this application; the terms "including" and "having" and any variations thereof in the specification and claims of this application and the above-mentioned drawings are intended to cover non-exclusive inclusions. The terms "first", "second", etc. in the specification and claims of this application or the above-mentioned drawings are used to distinguish different objects, not to describe a specific order.

[0032] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0033] The utility model embodiment provides a flange positioning tool, such as Figure 1-Figure 7 As shown, the flange positioning tool is applied to the flange outer side wall processing process, comprising:

[0034] The fixing plate 100 and the guide assembly 300; the guide assembly 300 includes an assembly shell and two sets of driving rods 320 sliding on the assembly shell;

[0035] The limiting member 200 is disposed at both ends of the guide assembly 300. The limiting member 200 includes a connecting rod 210, an arc seat 220 and a pressing plate 230. The arc seat 220 is pressed against the inner wall of the flange, and the pressing plate 230 is pressed against the end surface of the flange. The connecting rod 210 extends into the assembly housing and is connected to the driving rod 320.

[0036] The guide assembly 300 is provided with an adjusting member 400 inside, and the adjusting member 400 is rotatably connected with the driving rod 320. The rotation of the adjusting member 400 will push the driving rod 320 to perform centrifugal motion, and the arc seat 220 and the pressure plate 230 provided on the limiting member 200 will respectively apply pressure to the end face and the inner wall of the flange under the centrifugal action to achieve the effect of limiting locking;

[0037] In the present application, the flange positioning tool is mainly used in the flange outer wall processing process, so the fixing plate 100 and the pressing plate 230 form a clamping mechanism, which clamps different end faces of the flange workpiece respectively, and cooperates with the annular support of the arc seat 220 to fix the flange from multiple directions;

[0038] The pressure plate 230 and the arc seat 220 can also be fastened for a second time after the fixation is completed, which is different from the conventional clamping plate structure that can only apply pressure during the pushing process; the pressure plate 230 can also be further adjusted after the arc seat 220 is pushed into place, thereby enhancing the positioning and fixing effect of the flange positioning tooling;

[0039] As a preferred implementation in this embodiment, the assembly shell includes a bottom plate 310 and an outer shell; a slide groove 331 is provided on the bottom plate 310, and the driving rod 320 includes a rack rod 321 and a support rod 322, the rack rod 321 and the support rod 322 are vertically arranged, and the rack rod 321 and the support rod 322 are provided with guide sliders, and the rack rod 321 and the support rod 322 slide in different slide grooves 331 respectively; the driving rod 320 is in two groups, which are arranged on the bottom plate 310 in a centrally symmetrical manner;

[0040] The connecting rod 210 extends into the interior of the outer shell through the opening provided on the side wall of the outer shell, and is connected to the support rod 322. When the driving rod 320 moves, it will drive the connecting rod 210 to move synchronously.

[0041] A shaft 330 is also provided at the center of the bottom plate 310. The adjusting member 400 includes a rotating disk 410 and an external gear 420. An axial hole is provided on one end face of the rotating disk 410. A bearing 450 is provided in the axial hole. The rotating disk 410 is assembled on the shaft 330 through the bearing 450, and the external gear 420 is provided on the peripheral side of the rotating disk 410. The external gear 420 is arranged on the peripheral side of the rotating disk 410 in a ring array. The rack rod 321 is provided with a rack structure adapted thereto and the two are meshed with each other. Therefore, when the rotating disk 410 rotates, the external gear 420 drives the rack rod 321 to perform linear motion. The adjusting member 400 will serve as a power source for the guide assembly 300.

[0042] The rotating disk 410 extends out of the assembly shell from the outer shell away from the side of the shaft rod 330, and the rotating disk 410 part located outside the assembly shell is operated during operation; the rotating disk 410 is also provided with a plurality of groups of limiting screw holes 430, and the limiting screw holes 430 extend from the rotating disk 410 away from the end face of the shaft rod 330 to the shaft hole, and the limiting bolts 440 are arranged in the limiting screw holes 430, and the limiting bolts 440 are screwed into the limiting screw holes 430 and abut against the shaft rod 330 assembled in the shaft hole; the contact surfaces of the shaft rod 330 and the limiting bolts 440 are both planar structures with high friction, and the flange positioning tooling generally rotates during use, so the limiting member 200 is more tightly combined with the inner wall of the flange under the action of centrifugal force; and the present application mainly relies on the end face clamping force to improve the fixing effect, and the limiting of the shaft rod 330 and the limiting bolts 440 during the grinding process can meet the needs of limiting support;

[0043] As a preferred implementation in this embodiment, a limiting hole is provided on the pressing plate 230, and a fastening bolt 240 is provided in the limiting hole; one end of the fastening bolt 240 is provided with a threaded structure, and the other end is a needle seat, and a rotating bearing is provided on the outer side of the needle seat of the fastening bolt 240, and the outer wall of the rotating bearing is fixedly connected to the limiting hole, so under the action of the rotating bearing, when the needle seat of the fastening bolt 240 rotates, the pressing plate 230 will not rotate accordingly, but when the fastening bolt 240 approaches the arc seat 220, the pressing plate 230 will also decrease in height synchronously to achieve the purpose of pressing;

[0044] The purpose of using the bearing structure transmission here is to use the height change of the fastening bolt 240 to drive the pressure plate 230 to move. If ordinary structural bolts are used, the pressure plate 230 and the fastening bolt 240 are separated structures. During the docking process, the pressure plate 230 will move to the fixed plate 100 side in advance under the action of its own weight, and the flange cannot be placed between the pressure plate 230 and the fixed plate, affecting the assembly;

[0045] The working process of the present application is implemented as follows: first, the flange is nested outside the limiter 200 and one end face thereof is pressed against the fixing plate 100, and the turntable 410 extending out of the assembly shell is rotated to make the arc seat 220 of the limiter 200 press against the inner wall of the flange, and then the limit bolt 440 is tightened; the circumferential limit fixation is completed, and then the fastening bolts 240 on different limiters 200 are adjusted, and the end face pressing force is generated by the pressing plate 230 to further improve the fixing effect of the flange;
