[0029] The working principle of the pyramid sleeve type uncoiler reel sector plate processing fixture provided by the present invention is as follows: according to the maximum diameter of the sector plate unit 9 to be processed and the diameter size of the pyramid sleeve 1001 of the matching pyramid sleeve unit 10, a slider 6 of corresponding height is selected; according to the axial length of the sector plate unit 9 to be processed and the length size of the pyramid sleeve 1001 of the matching pyramid sleeve unit 10, the slider 6 is fixed to the corresponding position of the guide rail 12 by screws 7 and pins 8; at this time, the pyramid sleeve unit 10 is inserted, and one end of the pyramid sleeve 1001 is in contact with the corresponding slider 6 for positioning, and the other end of the pyramid sleeve 1001 is in contact with the corresponding slider 6.

Subsequently, the core shaft 1 of the pyramid sleeve type uncoiler reel fan-shaped plate processing fixture is extended out of the circular left baffle 4 and connected to the three-jaw chuck of the lathe. The core shaft 1 of the pyramid sleeve type uncoiler reel fan-shaped plate processing fixture is extended out of the circular right baffle 2 and connected to the top of the lathe. Finally, the fan-shaped plate unit 9 is turned.

[0030] The pyramid sleeve type uncoiler reel drum sector plate processing fixture provided by the utility model has adjustability as its most critical feature compared with traditional processing fixtures. Since the axial positions of the sliders 6 on the core shaft 1 of the pyramid sleeve type uncoiler reel drum sector plate processing fixture are adjustable, it is suitable for the rounding requirements of a type of reel with the same pyramid sleeve unit 10 inner hole, where only the end face of the sector plate unit 9 and the end face of the pyramid sleeve unit 10 in the length direction have different distances when in the true circle state, and its applicability is significantly enhanced.

[0031] The slide block 6 used simultaneously can be divided into one group and stored in groups. When the pyramid sleeve unit 10 used by the sector plate unit 9 of the reel cooperates with the endoporus to be larger or smaller, it is necessary to prepare one group of slide blocks 6 for distribution and identification.

[0032] During use, the pyramid sleeve uncoiler reel sector plate processing fixture only needs to move and equip the slider 6 accordingly according to the use requirements, which effectively reduces the company's tooling costs in reel processing and helps the company achieve cost reduction and efficiency improvement.

[0033] The core shaft 1 can be equipped with multiple sets of sliders 6 with different outer circles to meet the needs of clamping and positioning the sector plate units 9 of the pyramid sleeve type reel with the inner holes of the pyramid sleeve units 10 of various specifications.
