Be connected with driven screw rod on the described supporting roller, steel ball is equipped with in the end of driven screw rod, and described steel ball contacts with the edge cam that is installed in casing rear bearing place, and the end face track of edge cam is determined the movement law of main shaft.

Beneficial effect: a kind of intersection facing attachment of the present invention, three kinds of motion modes are integrated in the small parts, have delicate structure compactness, reliable operation, characteristics that production efficiency is high; In process, take workpiece to fix and cutter rotation, near part and realize the mode of chamfering, can solve the chamfering difficult problem of the intersection angle of cut that forms between part processing mesopore and the hole, effectively solve the chamfer machining of place, crossing hole such as automobile engine cylinder-body, diesel engine cylinder block, air-conditioning valve body wedge angle, operating efficiency obtains bigger raising, is particularly suitable for using on the rotating disc type building-block machine of multistation, many unit heads, multiple clip and the transfer matic.

Description of drawings

Fig. 1 is structural representation of the present invention.

The specific embodiment

Below in conjunction with accompanying drawing the present invention is done further explanation.

As shown in Figure 1, a kind of intersection facing attachment of the present invention comprises the pulley gear 11 that cutter 2 is rotated, and makes cutter 2 near the rotary cylinder 12 at work piece 1 angle of cut place, and the cylinder 7 that cutter 2 is moved forward and backward; Pulley gear 11 is connected with main shaft 6, and knife bar 3 is housed in the hole of main shaft 6, and knife bar 3 tops are cutters 2; The cylinder 7 that cutter 2 is moved forward and backward is connected with support 8, and support 8 is provided with one group of roller 9, and roller 9 drives the supporting roller 14 that is installed on the main shaft 6 and moves, thereby makes main shaft 6 along with supporting roller 14 moves forward and backward; The piston of rotary cylinder 12 is connected with push rod 20, and push rod 20 is rotationally connected with knife bar 3, and push rod 20 promotes knife bar 3 and rotates, thereby makes the intersection angle of cut place of cutter 2 near work piece 1.

In the present embodiment, pulley gear 11 and supporting roller 14 all are connected with main shaft 6, knife bar 3 and push rod 20 all are contained in main shaft 6 holes, cutter 2 is contained in knife bar 3 front aperture, main shaft 6 is contained in the fore bearing 19 and rear bearing 17 holes in casing 18 holes, rotary cylinder 12 is connected with pulley gear 11 and push rod 20, and cylinder 7 is contained in above the casing 18.Be connected with driven screw rod 13 on the supporting roller 14, steel ball 15 is equipped with in the end of driven screw rod 13, and steel ball 15 contacts with edge cam 16 on being installed in rear bearing 17, and the end face track of edge cam 16 is determined the movement law of main shaft 6; Push rod 20 links to each other by second hinge 21 with knife bar 3, and knife bar 3 links to each other by first hinge 5 with main shaft 6, and the movement of rotary cylinder 12 pistons makes the cutter 2 on the knife bar 3 rotate and near the intersection angle of cut place of work piece 1 around first hinge 5.
