In this embodiment, 4 chip removal holes 12 are formed in the worktable 1, the chip removal holes 12 concentrically correspond to the rotating shaft 42, a limiting groove 111 is formed in the through hole 11, and a sliding key 311 slidably connected with the limiting groove 111 is formed on the positioning pin 31. The chip removal hole 12 is used for removing scraps generated in the machining process, and the limiting groove 111 and the sliding key 311 are used for limiting, so that the positioning pin is prevented from being ejected by a spring.

In this embodiment, a guide rail is fixedly connected to the positioning frame 22, the positioning chuck 24 is slidably connected to the guide rail, an end cover 29 is fixedly connected to the positioning frame 22, and a rectangular notch through which the positioning chuck 24 can pass is formed in the end cover 29. The end cap 29 is used for limiting and preventing the positioning chuck 24 from sliding out.

The working process and the principle thereof are as follows:

when needs tapping, earlier manual work or manipulator place the flange on workstation 1, the hole of this in-process only need the flange contain central positioner 2 wherein can, need not accurate location. After the flange is placed on the workbench 1, because the position is not located at the center, the positioning pin 31 is pressed into the through hole 11 by the flange due to the gravity of the flange, the spring 32 is compressed, the sliding column 35 slides downwards, the first contact 36 is communicated with the second contact 37, and the controller detects the electric signal to control the positioning motor 63 to start.

The positioning motor 63 drives the worm wheel 61 to rotate through the worm 62, thereby driving the turntable 21 to rotate through the hollow shaft 28. The turntable 21 rotates, and the pulley 25 is located in the sliding groove 211 of the turntable 21 because the positioning frame 22 is fixed at this time, and the sliding groove 211 exerts a force on the pulley 25, so that the pulley 25 starts to slide along the sliding groove 211. On the other hand, since the pulley 25 is rotatably connected to the bottom of the collet 24, and the collet 24 is slidably connected to the positioning frame 22, the collet 24 starts to extend outwardly by the force of the sliding slot 211 applied to the pulley 25. In the process, the three positioning chucks 24 extend synchronously, so that the flange is corrected continuously until the flange is positioned at the right center, and when the flange is positioned at the right center, the positioning chucks 24 just tightly abut against the inner hole of the flange (when the positioning motor 63 is turned off, the motor can be turned off according to actual conditions to control the number of turns of the motor). Since the driving mechanism of the rotary disc 21 is the worm wheel 61 and the worm 62, when the motor is turned off, the rotary disc 21 is in a self-locking condition and cannot be loosened.

After the preliminary positioning is finished, the rotating motor 27 is started to drive the whole central positioning device 2 to start to rotate at a constant speed, the flange is fixed by the positioning chuck 24 and rotates at a constant speed, when the flange rotates to the position that the positioning hole of the flange is concentric with the through hole 11 on the workbench 1, the positioning pin 31 can be upwards ejected out of the positioning hole under the elastic force action of the spring 32, when the pressure of the spring 32 is released, the sliding column 35 slides upwards, the contact I36 is separated from the contact II 37, the controller detects the electric signal, the secondary positioning is judged to be finished, and then the rotating motor 27 is controlled to be closed.

The rotating motor 27 is turned off, the tapping motor 41 and the lifting motor 71 are started, the lifting motor 71 drives the lifting gear 73 to rotate, and the lifting gear 73 drives the driven gear two 74 to rotate. The two lead screws 75 are driven by the rotation of the second driven gear 74 to start rotating, and since the lead screws 75 are connected with the lead screw nuts 76 on the third fixing plate 45, when the lead screws 75 rotate, the third fixing plate 45 descends to drive the whole tapping device 4 to descend, and the third fixing plate 45 slides down along the sliding rods 77 during descending, and the sliding rods 77 play a role of balance assistance.

The tapping motor 41 is started to drive the tapping gear 46 to rotate so as to drive the 4 driven gears 47 to rotate simultaneously, the driven gears 47 are fixed on the rotating shaft 42, and the rotating shaft 42 is rotatably connected with the first fixing plate 43 and the second fixing plate 44, so that the rotating shaft 42 can be driven by the driven gears 47 to rotate, the rotating shaft 42 rotates to drive the clamping head 48 to rotate, and the clamping head 48 is a device which is commonly used for clamping a tap 49 or a drill bit in drilling and tapping machines at present.

The tap 49 rotates and descends to tap a reserved hole in the flange, and the tapping motor 41 and the lifting motor 71 can be adjusted according to actual processing requirements to see whether proper reverse rotation is needed for chip removal. The tapped scrap can be discharged through the clearance holes 12.

After tapping is completed, the positioning motor 63 rotates reversely, the positioning chuck 24 retracts, the flange is loosened, and then the flange is taken down. The tapping device 4 can replace the tap 49 with a drill bit, so that the requirement of the device on flange drilling is met, and the application range of the device is widened.

Based on the above: the center positioning device is matched with the hole positioning device for use, manual positioning and clamping are not needed, the automation degree is high, the positioning error is small, the tapping device adopts 4 screw taps for the same-row operation, the tapping efficiency is high, repeated positioning and clamping are not needed, and the large-batch processing requirement is met.

It will be appreciated by those skilled in the art that the invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof. The embodiments disclosed above are therefore to be considered in all respects as illustrative and not restrictive. All changes which come within the scope of or equivalence to the invention are intended to be embraced therein.
