Embodiment 1

[0038] combined with Figure 1~6 , a kind of slitting disc blade coaxial precision machining special tooling of the present embodiment (such as figure 1 , figure 2 and Figure 6 shown), including mandrel spindle, sleeve unloading device, open taper sleeve 3, taper sleeve fixing mechanism and cutter body pressing mechanism.

[0039] The mandrel spindle (as image 3 (shown) is a whole, and the mandrel spindle is provided with a pressing plate 11, a sleeve unloading device installation section 12, a tapered transition section 13, a first threaded section 14 and a second threaded section 15 in sequence along its length direction. The pressure plate 11 is a disc structure, and the right side of the pressure plate 11 is uniformly provided with 6 threaded holes along the outer periphery of the sleeve unloading device installation section 12 . The diameter of the sleeve unloading device installation section 12 is consistent with the inner diameter of the sleeve unloading device o...

Embodiment 2

[0053] The special tooling for precision machining of the coaxiality of slitting disc blades in this embodiment is basically the same as that in Embodiment 1, except that the tapered transition section 13 is made of The cylindrical section and the conical section are composed, the circular section is connected with the installation section 12 of the unloading device, the diameter of one end where the conical section joins the cylindrical section is greater than the diameter of the other end, and the taper of the conical section is also 11°. The right side of the pressure plate 11 is evenly provided with 8 threaded holes along the outer periphery of the sleeve unloading device installation section 12, and the first unloading plate 21, the second unloading plate 22 and the third unloading plate 23 8 threaded holes are uniformly opened along the ring body. The method of using the special tooling for coaxial precision machining in this embodiment is the same as that in Embodiment ...

Embodiment 3

[0055] A special tooling for precision machining of the coaxiality of slitting disc blades in this embodiment is basically the same as in Embodiment 2, except that the side where the open taper sleeve 3 and the taper sleeve pressure plate 5 are adjacent is about the central axis Threaded holes are symmetrically opened, and the taper sleeve pressure plate 5 and the open taper sleeve 3 are fixedly connected with bolts on the side adjacent to each other. When the sleeve 3 is unloaded, the open taper sleeve 3 can be pulled out through the taper sleeve pressing plate 5 . The right side of the pressure plate 11 is evenly provided with 10 threaded holes along the outer periphery of the sleeve unloading device installation section 12, and the first unloading plate 21, the second unloading plate 22 and the third unloading plate 23 are uniformly provided with 10 threaded holes. 10 threaded holes are uniformly opened along the ring body. The method of using the special tooling for coaxi...

Abstract

The invention discloses a special tool for accurate coaxiality processing of a slitting disk cutter blade as well as a using method of the special tool, belonging to the technical field of mechanical cutter blade processing. The special tool comprises a core rod main shaft, a sleeve removing device, an opened taper sleeve, a taper sleeve fixing mechanism and a cutter body pressing mechanism, wherein the core rod main shaft is provided with a pressing plate, a sleeve removing device installation section, a tapered transition section, a first thread section and a second thread section in sequence along the length direction; the sleeve removing device is positioned at the right side of the pressing plate and is arranged outside the sleeve removing device installation section in a sleeved manner; the opened taper sleeve is arranged outside the tapered transition section in a sleeved manner; the taper sleeve fixing mechanism is movably connected with the first thread section by a thread and is used for fixing the opened taper sleeve; the cutter body pressing mechanism is movably connected with the second thread section by a thread and is used for pressing and fixing the slitting disk cutter blade. The special tool can meet the requirement of the processed slitting disk cutter blade on coaxiality accuracy of internal and external circles, the processing pass percent is high, and the processing cost is reduced.

Description

technical field [0001] The invention relates to the technical field of blade processing, and more specifically relates to a special tooling for precision machining of the coaxiality of slitting disc blades. Background technique [0002] With the development of society, the machining accuracy of workpieces in the machining industry has also entered the stage of micron-level ultra-precision control. In the metal slitting industry, the slitting disc blades used for slitting metal foils with double zero thickness (such as copper foil, aluminum foil, etc.) require high coaxiality and flatness to control the shearing of products. cut quality. In the domestic finishing industry, the flatness has been able to meet the micron-level requirements of the product through grinding, but the coaxiality of the slitting disc blade has always been a bottleneck for domestic manufacturers. [0003] At present, domestic manufacturers of slitting disc blades mostly process the disc blades on the...
