The specific embodiment

Extremely shown in Figure 4 like Fig. 1; Automobile spoke is processed two-sided multiaxis spot-facer; Mainly comprise fuselage 1, support 4 and workbench 5; It is characterized in that: also include lead 3, last axles box 7, upper cylinder 8, following axles box 14, following oil cylinder 13, compressor arm 11 and compressed oil cylinder 15, lead 3 is anchored on the axles box 7;

The said axles box 7 of going up is to be installed on the fuselage 1 through upper rail 2, and upper cylinder 8 is connected with last axles box 7, and drives last axles box 7 through upper cylinder 8 and move as upper-lower position; The some spot-facing chmfer bits 10 of going up of distributed quantity are along the circumferential direction stretched out in the lower surface of last axles box 7; And the round center of spot-facing chmfer bit 10 is equipped with a centre bore processing upper tool pan 9 in said circumferencial direction distribution; Reach from last axles box 7 interior centers, lower end and stretch out splined shaft 17, also be equipped with on the said fuselage 1 to drive and go up the main power source master motor 18 that axles box 7 inner shafts rotate.

Said axles box 14 down is to be installed on the support 4 through lower guideway 20, and following oil cylinder 13 is connected with following axles box 14, and does moving of upper-lower position through axles box 14 under oil cylinder 13 drives down; The some spot-facing chmfer bits 12 down of distributed quantity are along the circumferential direction stretched out in the upper surface of following axles box 14; And the round center of the following spot-facing chmfer bit 12 that said circumferencial direction distributes be equipped with a centre bore process under cutterhead 19; And spline housing 16 is stretched out, said this spline housing 16 and splined shaft 17 mutual fits settings in the centers, upper end in following axles box 14.

Workbench 5 is located between axles box 7 and the following axles box 14; And be position, upper end at following axles box 14; The compressed oil cylinder 15 that compressor arm 11 also is installed on the said workbench 5 and is connected with compressor arm 11 drives compressor arm 11 through compressed oil cylinder 15 workpiece 6 is firmly placed on the workbench 5.

Operation principle of the present invention is: extremely shown in Figure 7 like Fig. 1, Fig. 2 and Fig. 5; Workpiece 6 to be processed is placed on the workbench 5 between the upper and lower spot-facing chmfer bit (10,12) of upper and lower axles box (7,14); And workpiece 6 is positioned on the fixing workbench 5 through the effect of compressed oil cylinder 15 and compressor arm 11; When last axles box 7 moved downward and down axles box 14 moves upward, the upper and lower countersink drill (10,12) on two casees and upper and lower cutterhead (9,19) got into to upper and lower two faces of workpiece 6 simultaneously and process.

Drive last spot-facing chmfer bit 10 and the upper tool pan of going up on the axles box 79 by main power source master motor 18; When cut is carried out in last axles box 7 downward feedings; The splined shaft 17 that stretch out at last axles box 7 centers begins to insert down in the middle of the spline housing 16 on the axles box 14; And driven following spot-facing chmfer bit 12 and the rotation of cutterhead 19 down on time axles box 14, at this moment, upper and lower spot-facing chmfer bit (10,12) is a shared power source that comes from main motor 18 when processing work 6.

In addition because the end face of upper and lower spot-facing chmfer bit (10,12) is designed to the mutual plug-type structure of tapering; When last axles box 7 moves downward the entering cutting; The taper hole 101 of last spot-facing chmfer bit 10 is worked in coordination with the axis of cone 121 of following spot-facing chmfer bit 12 and is played the centering effect; Thereby strengthened the rigidity of auger spindle, in process, guaranteed the axiality of upper and lower spot-facing chmfer bit (10,12).

As shown in Figure 6, the last hole processing of workpiece has been accomplished in the roughing of spot-facing chmfer bit 10 in the utilization; As shown in Figure 7, utilize the fine finishining of spot-facing chmfer bit 12 down, accomplished the processing in the following hole of workpiece.

Advantage applies of the present invention in sum in: the first, utilize the whole big aperture and the chamferings of the upper and lower surface of spot-facer processing automobile spoke of the present invention, and on same lathe, accomplish simultaneously, need not stirring of workpiece, time saving and energy saving; The second, the end face of upper and lower spot-facing chmfer bit (10,12) is designed to the mutual plug-type structure of tapering, and the mode that in the process of processing, cooperates with axis hole has mutually really realized coaxial processing up and down, and machining accuracy is high; The 3rd, the power of following axles box 14 is to be gone into by last axles box 7 spline housing 16 that splined shaft 17 is inserted in down axles box 14 centers through the center, and stagger zero load year the process time of upper and lower spot-facing chmfer bit (10,12) mutually.
