[0026] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments: Example

[0027] See also Figure 1-Figure 7 , an aluminum pan head shaft threading device, including a base frame, a fixed guide rail is arranged on the base frame, a mobile taper device 4 is slidingly arranged on the guide rail, a first shaft support 41 for supporting one end of the central shaft and an electromagnetic component 42 for adsorbing the central shaft are arranged on the mobile push-pull device 4, a second support 43 is arranged on the base frame in front of the first shaft support 41, the second support 43 is used to support the other end of the central shaft, the central shaft is in a horizontal state through the joint action of the first shaft support 41 and the second support 43, the electromagnetic component 42 can magnetically adsorb the central shaft, and then can drive the central shaft to move synchronously when the mobile push-pull device 4 moves.

[0028] The base frame is also provided with a support unit 1 for supporting the aluminum disk 3 and a detection unit 2 for detecting the edge of the aluminum disk head 3. The support unit 1 includes a first shaft 11 and a second shaft 12. The first shaft 11 and the second shaft 12 are both rotatably arranged on the base frame. The first shaft 11 is connected to a driving motor. The driving motor rotates to drive the first shaft 11 to rotate. The first shaft 11 and the second shaft 12 are connected by a pair of gears to achieve power transmission. The two rotate in opposite directions. A plurality of rotating grooves are provided on the first shaft 11. A rotating sleeve 111 is rotatably arranged in each rotating groove. A clutch is passed between the rotating groove and the rotating sleeve 111. The clutch includes a magnetic part 141 and an electromagnetic part 132. A plurality of magnetic parts 141 are evenly arranged on the circumference of the side end wall of the rotating sleeve 111, and a plurality of electromagnetic parts 142 are evenly arranged on the corresponding groove wall. When the electromagnetic part 142 is energized, the magnetic part 141 can be adsorbed.

[0029] When the electromagnetic member 142 is powered on, after the first shaft 11 rotates by an angle, the electromagnetic member 142 is aligned with the magnetic member 141 , and the electromagnetic member 142 absorbs the magnetic member 141 , so that the first shaft 11 rotates and drives the rotating sleeve 111 to rotate.

[0030] The second shaft 12 is provided with a grinding device 13, which includes a rotating member 131 and a grinding member 132 sleeved on the axial surface of the rotating member 131. The grinding member 132 is an airbag, which can swell to form an inflatable cylinder after being inflated. Grinding gravel is adhered to the surface of the grinding member 132. The second shaft 12 is also provided with a same rotating groove at a position corresponding to the first shaft 11. The rotating member 131 is rotatably arranged in the rotating groove of the second shaft 12. At the same time, a side end wall of the rotating member 131 is also provided. A magnetic component 141 is provided, and an electromagnetic component 142 is provided on the corresponding rotating groove wall, and a hollow channel is provided between the magnetic component 141 and the electromagnetic component 142 on the second shaft 12, the airbag is connected with the hollow channel of the magnetic component 141 through an internal pipeline, the hollow channel on the electromagnetic component 142 is connected with the rotating air intake head connected to one end of the second shaft 12, and a solenoid valve is provided on the hollow channel on the electromagnetic component 142, and a sealing ring is provided on the joint surface of the electromagnetic component 142 and the magnetic component 141.

[0031] When the electromagnetic component 142 is energized, the magnetic component 141 is adsorbed. At this time, the electromagnetic component 142 is connected to the hollow channel of the magnetic component 141. At the same time, since the sealing rings on the two are tightly fitted, when the electromagnetic component 142 is energized, the solenoid valve is opened synchronously, and the compressed air input from the rotating air inlet head can enter the airbag, causing the airbag to expand to form an airbag column, and the rotation of the second shaft 12 drives the rotating component 131 to rotate.

[0032] A limit ring 1111 is provided on the rotating sleeve 111, and a damping layer is provided on the surface of the rotating sleeve 111. The damping layer can be made of polyurethane, epoxy resin, butyl rubber and nitrile rubber, so that the surface of the rotating sleeve 111 has a certain flexibility and the friction coefficient of the surface is improved. When the operator places the aluminum pan head on the first shaft 11 and the second shaft 12 through a manipulator, the aluminum pan head 3 is located in the left and right limit rings of the rotating sleeve 111. At this time, the first shaft 11 rotates. When the aluminum pan head 3 needs to rotate, the electromagnetic part 142 on the first shaft 11 is energized, thereby driving the rotating sleeve 111 to rotate. The rotating sleeve 111 drives the aluminum pan head 3 to rotate through friction, and at this time, the electromagnetic part 142 on the second shaft 12 is not energized, so the rotating part 131 rotates with the aluminum pan head 3, which is opposite to the rotation direction of the second shaft 12.

[0033] When it is necessary to grind the edge of the aluminum pan head, the electromagnetic part 142 on the second shaft 12 is energized, and then the second shaft 12 is connected to the rotating part 131 as a whole. At the same time, the grinding part 132 is inflated to form an inflatable column. Since the aluminum pan head has a large gravity, the airbag wall at the position of the aluminum pan head is tightly attached to the rotating part 131, and then the airbag wall is tightly attached to the edge of the aluminum pan head. At this time, the second shaft 12 drives the rotating part 131 to rotate, and the rotation direction is opposite to that of the aluminum pan head, so that the edge of the aluminum pan head is grinded when the aluminum pan head rotates.

[0034] The detection unit 2 includes a detection frame 21, a detection member 22 and a telescopic member 23. The telescopic member 23 is arranged on the base frame, the detection frame 21 is arranged at the front end of the telescopic rod of the telescopic member 23, and the detection member 22 is arranged on the detection frame 21. When the telescopic member 23 is extended forward, the detection member 22 can be extended to the edge position of the aluminum pan head 3 on the first axis 11 and the second axis 12. The detection member 23 includes a pull rope 221 and a tension detector. One end of the pull rope 221 is fixedly arranged on the detection frame 21, and the other end is connected to the tension detector.

[0035] When detection is needed, the telescopic part 23 pushes the detection part 23 to the edge of the aluminum pan head. At this time, the pull rope 221 presses on the edge of the aluminum pan head, and the aluminum pan head rotates the pull rope 221 to fit tightly against the edge. When a concave-convex notch appears on the edge, the cutting edge of the concave-convex notch will trip the pull rope 221, and then the tension on the tension detector increases. The greater the tension when tripping, the greater the tension acting on the tension detector. The air pressure value filled into the polishing part 132 is controlled by the amplitude of the tension change. The central control device can analyze the tension change detected by the tension detector, control the air pressure filled into the polishing part 132 according to the size of the tension change, and adjust the pressure of the polishing part 132 on the edge of the aluminum pan head.

[0036] Since the grinding piece 132 exerts an extrusion pressure perpendicular to the gravity on the edge of the aluminum pan head along the axis of the aluminum pan head after being inflated, and at the same time, when the air pressure in the grinding piece 132 is at its maximum, the airbag wall at the contact position with the aluminum pan head is also tightly attached to the surface of the rotating piece 131. Therefore, increasing the air pressure value in the grinding piece 132 will only increase the pressure of the airbag surface on the edge of the aluminum pan head. The greater the pressure, the better the grinding effect. Therefore, the greater the tension detected on the tension detector, the greater the air pressure filled into the grinding piece 132, and the cutting edge of the knocked-out part can be polished away, so that the bumped part and the surrounding area are smoothly transitioned and will not get caught when the spinning line passes through.

[0037] An elastic locking block 31 is arranged on the side wall of the aluminum pan head 3. In the initial state, the elastic locking block 31 is retracted into the aluminum pan head 3 and can extend outward when subjected to magnetic attraction. A plurality of locking electromagnetic components 15 are arranged on the base frame. A concave cavity 151 is arranged in the middle of the locking electromagnetic component 15. When power is turned on, the magnetic force at the bottom of the concave cavity 151 is greater than the magnetic force on the surface of the locking electromagnetic component 15, and the shape of the concave cavity 151 is adapted to the elastic locking block 31.

[0038] After the grinding is completed, the locking electromagnetic component 15 is energized, and the aluminum pan head 3 is still rotating driven by the rotating sleeve 111. After the grinding is completed, the control unit controls the speed of the driving motor to decrease, so that the aluminum pan head 3 rotates slowly. When the elastic locking block 31 on the aluminum pan head 3 rotates to the locking electromagnetic component 15, the elastic locking block 31 extends outward and touches the surface of the locking electromagnetic component 15. When it is aligned with the concave cavity 151, it is sucked into the concave cavity 151, and then the aluminum pan head is locked in the locking electromagnetic component 15. After the elastic locking block 31 is sucked into the concave cavity 151, the electromagnetic component 142 on the first shaft 11 at this position is powered off, and the rotating sleeve 111 at this position is disconnected from the first shaft.

[0039] Its working principle or usage is as follows: After the operator accurately places the aluminum pan head on the first shaft 11 and the second shaft 12, the central control unit controls the drive motor to rotate, so that the first shaft 11 starts to rotate, and at the same time controls the electromagnetic part 142 on the first shaft 11 to be energized. After the first shaft 11 rotates and moves an angle, the electromagnetic part 142 is aligned with the magnetic part 141, and the electromagnetic part 142 absorbs the magnetic part 141. Then the rotation of the first shaft 11 drives the rotating sleeve 111 to rotate, and the rotating sleeve 111 drives the aluminum pan head to rotate.

[0040] The telescopic part 23 pushes the detection part 23 to the edge of the aluminum pan head. At this time, the middle section of the pull rope 221 presses against the edge of the aluminum pan head, and the aluminum pan head rotates the pull rope 221 to fit tightly against the edge. At this time, if the tension value detected by the tension detector does not change significantly, that is, it is within the intact tension value range of the aluminum pan head set in the central control unit, then no grinding operation is performed.

[0041] When the tension value exceeds the set range, the central control unit controls the electromagnetic part 142 on the second shaft 12 to be energized, and then the second shaft 12 is connected to the rotating part 131 as a whole, and at the same time the polishing part 132 is inflated to form an inflatable column. Since the aluminum pan head has a large gravity, the airbag wall at the position in contact with the aluminum pan head is tightly attached to the rotating part 131, and then the airbag wall is tightly attached to the edge of the aluminum pan head. At this time, the second shaft 12 drives the rotating part 131 to rotate, and the rotation direction is opposite to the rotation direction of the aluminum pan head. Then, when the aluminum pan head rotates, the edge of the aluminum pan head is polished. The greater the tension detected on the tension detector, the greater the air pressure filled into the polishing part 132.

[0042] During the grinding process, the detection part 23 continuously detects the edge. When the tension value returns to the set range, the electromagnetic part 142 on the second shaft 12 is controlled to be powered off, the second shaft 12 is disengaged from the rotating part 131, and the gas in the grinding part 132 leaks out from the gap between the rotating part 131 and the rotating groove, and the grinding device 13 stops grinding.

[0043] After the grinding is completed, the locking electromagnetic component 15 at this position is energized, and when the elastic locking block 31 on the aluminum pan head 3 rotates to the locking electromagnetic component 15, the elastic locking block 31 extends outward and touches the surface of the locking electromagnetic component 15, and when it is aligned with the concave cavity 151, it is sucked into the concave cavity 151, and then the aluminum pan head is locked in the locking electromagnetic component 15. After the elastic locking block 31 is sucked into the concave cavity 151, the electromagnetic component 142 on the first shaft 11 at this position is powered off, and the rotating sleeve 111 at this position is disconnected from the first shaft, and the rotating sleeves 111 at other positions continue to rotate. After all the aluminum pan heads 3 are locked, the first shaft 11 stops rotating. At this time, the key slots of all the aluminum pan heads 3 are in a straight line, and the mobile push-pull device 4 pushes the central axis to the aluminum pan head, thereby completing the shaft threading work. Example

[0044] The difference from the first embodiment is the structure of the detection element 22, which is the same as that of the first embodiment, see Figure 1-Figure 7 The detection part 22 is a visual camera, which detects the corners of the trip wire gap through visual recognition when the aluminum pan head rotates. The central control unit adjusts the air pressure value filled into the polishing part 132 according to the size of the corners of the trip wire gap recognized by the visual camera. The larger the corners, the greater the air pressure value filled into the polishing part 132.
