[0002] The existing gantry five-axis machining center bears the machining of large and complex parts. The device adopts a double-swing-angle numerical control universal milling head, wherein the horizontal rotation is the C shaft with a swing angle range of 0-360°, and the vertical swing is the A shaft with a swing angle range of ±110°, the five-axis head A shaft swing length is less than or equal to 400 mm, and the electric spindle adopts the electric spindle of the KESSLER company with a speed range of 10-12000 r / min. The main scheme of the milling head adopts an A / C double-swing-angle milling head and a ram integrated structure. If the milling head fails and needs to be dismounted, a special dismounting auxiliary device is required. SUMMARY

[0003] The utility model aims at providing a milling head dismounting auxiliary device.

[0004] The utility model aims at providing a milling head dismounting auxiliary device.

[0005] The utility model relates to a kind of milling head dismounting auxiliary devices, including support part and four adjustable pad irons;Wherein support part is mainly used to place and fix milling head;Adjustable pad iron 300*140*100, adjustable height 12mm.

[0006] Working process:

[0007] When dismounting milling head, milling head is opened to appropriate position, it is ensured that it is placed on support, the support rod of milling head is placed in the middle of baffle, wherein z axis direction needs to be adjusted gradually using hand wheel, while observing the current of z axis, if there is increasing trend, stop immediately, finally dismount the fixing bolt on milling head;

[0008] When installing milling head, four adjustable pad irons are placed under the four corners of the device first;Then the auxiliary device is lifted to the upper of pad iron, first use level to adjust the auxiliary device (x and y direction need to be adjusted), then z axis is operated to the upper of milling head, the position of fixed bolt hole is adjusted by hand wheel gradually, after coarse adjustment, z axis is lowered with minimum ratio, then according to the position of plug-in connector and the position of bolt, the x and y direction of auxiliary device is fine adjusted, at this time, small hammer and other tools are needed to knock auxiliary device slightly, while observing the effect of plug-in connector butt joint, observing the current of z axis, after the teeth of connection part are tightly engaged, nut is tightened, z axis is lifted, and auxiliary device is withdrawn.

[0009] Beneficial effects

[0010] When disassembling and assembling the milling head, the auxiliary device is used to stably place the milling head, prevent the milling head from sliding on the device, and protect the milling head during transportation, especially during the installation process, the milling head needs to be kept completely horizontal, the four adjustable shims are placed under the device to adjust the level of the milling head in the x and y directions, and precise docking with the ram is realized. BRIEF DESCRIPTION OF DRAWINGS

[0011] Figure 1 It is a structure diagram of the milling head dismounting and assembling auxiliary device. DETAILED DESCRIPTION

[0012] The content of the utility model will be further described below in combination with the drawings and examples.

[0013] Examples

[0014] As Figure 1 shown, the milling head dismounting and assembling auxiliary device comprises a support part and four adjustable shims; the support part is mainly used for placing and fixing the milling head; the adjustable shim is 300*140*100, and the height can be adjusted by 12mm.

[0015] Working process:

[0016] When disassembling the milling head, the milling head is opened to a suitable position, and the milling head is placed on the support, the supporting rod of the milling head is placed in the middle of the baffle, the z-axis direction needs to be adjusted by a hand wheel, and the current of the z-axis is observed, if there is an increasing trend, stop immediately, and finally the fixing bolt on the milling head is disassembled;

[0017] When assembling the milling head, four adjustable shims are placed under the four corners of the device first; then the auxiliary device is lifted to above the shims, the auxiliary device is adjusted horizontally (x and y directions need to be adjusted) by using a level, then the z-axis is operated to be above the milling head, the position of the fixing bolt hole is adjusted by using a hand wheel, the position of the x and y directions is adjusted step by step, after coarse adjustment, the z-axis is lowered at the minimum ratio, then the x and y directions of the auxiliary device are finely adjusted according to the position of the plug-in connector and the position of the bolt, at this time, a small hammer and other tools are used to slightly knock the auxiliary device, the butt joint effect of the plug-in connector is observed, the current of the z-axis is observed, after the teeth of the connection part are tightly engaged, the nut is tightened, the z-axis is lifted, and the auxiliary device is removed.

Claims

1. A milling head dismounting assist device characterized by, It comprises a support part and four adjustable pads, wherein the support part is mainly used for placing and fixing the milling head; the adjustable pad is 300*140*100, and the height is adjustable by 12 mm.
