detailed description

The utility model will be further described below in conjunction with the accompanying drawings.

As shown in Figure 1-3, the utility model is a special-shaped hole profiling turning tooling, which is used for processing special-shaped holes of parts, including the base of the machine tool and the large pallet 1 and the middle pallet that are sequentially arranged on the guide rails of the base of the machine tool 2. The small carriage 3 is provided with a headstock 4 at the end of the machine tool base, and a motor spindle 5 is arranged inside the headstock 4. Among them, the large carriage 1, the middle carriage 2, and the small carriage 3 are snapped in sequence, and the motor spindle 5 A rotary clamping mechanism is arranged on the top, and a boring and feeding mechanism for workpiece special-shaped holes is installed on the small carriage 3 . The rotary clamping mechanism includes a template transmission shaft 6, a cam template 7 set on the template transmission shaft 6, a flange 8, a tooling fixture 9 fixedly arranged on the flange 8, a workpiece 10 arranged in the tooling fixture 9, and a template The transmission shaft 6 is set at the center of the flange 8 through the hexagonal fixing sleeve 21, and the flange 8 is connected to the motor spindle 5 and the template transmission shaft 6; And the square tool rest 12, the roller frame 11 is in contact with the cam template 7, and the square tool rest 12 is provided with a boring bar 13. The roller frame 11 is close to the outer edge of the cam template 7 through a control mechanism. The control mechanism includes a fixed plate 14, a top plate 15, and a guide post 16. The socket is provided with a spring 17, the other end of the guide post 16 is connected with the small carriage 3, and the middle position of the fixed plate 14 and the top plate 15 is connected by an adjusting screw 18. Small plank screw 19 and screw nut 20 are also provided with small plank 3 .

The working principle of the utility model is to remove the screw rod of the middle carriage, and rotate the small carriage 3, install the roller frame 11 in the screw hole of the fixing seat of the small carriage 3 and close to the cam template 7 through the spring 17, the cam template 7 Consistent with the inner cavity track of the workpiece 10, install the boring bar 13 and clamp it in the slot of the square tool holder 12, adjust the feed rate through the small carriage screw 19, install the hexagonal fixing sleeve 21, and install the hexagonal fixing sleeve 21 on the lathe method.
