[0023] In this embodiment, the slide 7 is sleeved on the outer periphery of the two guide rods 6 and is arranged to slide horizontally. The two ends of the spring 8 are respectively in contact with the inner side of the baffle 5 of the slide 7. Through the sliding of the slide 7 and the elastic force of the spring 8, the slide 7 automatically slides to the center position when it slides and deviates, and can be automatically adjusted.

[0024] In this embodiment, the lifting block 15 is sleeved on the outer periphery of the screw rod 14 and is threadedly connected. The thread directions of the two screw rods 14 are opposite. The lifting block 15 is driven to slide up and down by the rotation of the screw rod 14 and the action of the thread to adjust the lifting height of the positioning plate 12.

[0025] In this embodiment, the thread directions of the outer ends of the worm 17 are opposite, and the outer ends of the worm 17 are respectively meshed with the two worm wheels 16. The worm 17 drives the two worm wheels 16 to rotate, so that the two screws 14 rotate for balance adjustment.

[0029] It should be noted that the utility model is a universal angle processing device for double-tooth racks. When in use, the workpiece of the double-tooth rack to be processed is first positioned in front of the front turntable 13. When fixing it, the two positioning frames 23 are slid through the two telescopic rods by starting the double-axis cylinder 21 to clamp the workpiece. The motor 20 is started and the output shaft speed of the motor 20 is adjusted through the flat reducer 19, and the turntable 13 is driven to rotate so that the workpiece is rotated at different angles for processing. When it is necessary to adjust the horizontal position and the center height, the slide 7 is adaptively slid during the processing, and the slide 7 is automatically slid to the center position under the elastic force of the springs 8 on both sides of the slide 7. The knob 18 is rotated by using a tool, and the two ends of the worm 17 are meshed with the worm wheel 16 to rotate the two screws 14 and drive the lifting block 15 to slide up and down. Since the lifting block 15 is fixed to the rear of the positioning plate 12, the positioning plate 12 is driven to rise and fall synchronously to adjust the height position of the machining center.
