Description

Technical Field

[0001] This utility model relates to the field of flange manufacturing technology, and specifically discloses a reference center positioning device for flanges. Background Technology

[0002] A flange is a disc-shaped metal body with an inner ring wall, an outer ring wall, and an end face through hole. Flanges can be used as a sealing structure for connecting pipelines, and they can also be used in vehicle engineering, machine tool positioning, noise reduction and vibration damping, and other fields.

[0003] The flange manufacturing process is as follows: blanking, rough machining of the blank, lathe finishing, polishing and painting. After rough machining, the basic dimensions of the flange are determined. Then, production personnel can use a lathe and, according to the dimensions specified in the drawings, use milling cutters and drills to perform finishing processes such as drilling, reaming, and chamfering. Before the finishing process, production personnel need to stably mount the flange on the lathe and perform center positioning to ensure the accuracy of the flange machining. Currently, during the flange machining process, production personnel need to use linear measuring equipment to measure the distance between the flange's outer diameter and its center point. Using these parameters, the center point position of the flange is calculated, and the positions of the through holes on each end face are marked. Therefore, most flange manufacturing companies require dedicated flange center point positioning positions, relying on manual measurement to ensure the accuracy of flange processing. For flanges of different specifications and sizes, production personnel need to find the reference center of the flange according to the corresponding dimensions and make measurement marks. It can be seen that the reference center positioning of the flange requires a certain amount of manpower and takes a long time, resulting in a longer production cycle for a single flange and affecting the company's incremental output plan. Utility Model Content

[0027] A reference shaft 10 is rotatably mounted at the center of the frustum 3. The reference shaft 10 is rotatably engaged with the frustum 3 via a bearing assembly. The bottom end of the reference shaft 10 is located below the frustum 3. A horizontal plate 20 is fixedly mounted on the outer side of the bottom end of the reference shaft 10. The inner end of the horizontal plate 20 is fastened to the reference shaft 10. The outer side of the horizontal plate 20 is located outside the base 1. A column 21 is fixedly mounted on the horizontal plate 20. Both the horizontal plate 20 and the column 21 facilitate the assembly and disassembly of the reference shaft 10 for production personnel. The top end of the reference shaft 10 is located above the frustum 3. A reference ball 22 is fixedly mounted on the top end of the reference shaft 10. The reference ball 22 can be used to assist in determining the center reference point of the flange, thereby facilitating subsequent dimensional positioning work by production personnel.

[0028] The working principle of this utility model is as follows:

[0029] Production personnel can adjust the position of the slide block 5 according to the specifications and dimensions of the flange, and fix the position of the support cylinder 6 through the mating structure of the threaded rod 13 and the bolt 15. The production personnel can place the flange inside the device, ensuring one end face of the flange contacts the support surface 19, the other end face contacts the clamping plate 9 and the end cap 17 respectively, and the inner ring wall of the flange contacts the outer wall of the rotating rod 16, thus stably placing the flange inside the device. The production personnel can use the center position of the reference shaft 10 and the reference ball 22 to determine the center reference point of the flange, and then use a spirit level to measure from the reference ball 22 to mark the position of the through holes on each end face, facilitating subsequent finishing operations.
