[0002] In the actual production of traditional cold-bending forming units, if the production specifications need to be changed, the traditional way is to stop the equipment, manually replace the mold roller, and start the machine after adjustment. Since manually replacing the roller mold of the entire line is labor-intensive, the re-adjustment time is long, time-consuming, labor-intensive and inefficient. In order to solve this problem, there are many different specifications of roller main machines in the prior art. The roller main machine is a modular product and is fixed to the bottom machine base by bolts. When the production specifications need to be changed, the roller main machine can be directly replaced. After the roller main machine is replaced, the power end of the power mechanism needs to be connected to the input end on the roller main machine. Bolts are mainly used in the prior art to fix it to achieve power docking. This fixing method has low operating efficiency and high labor intensity. Utility Model Content

Therefore, the drawings and descriptions are illustrative in nature and are not intended to limit the scope of protection of the claims.

[0020] like Figures 1 to 7 As shown, a quick-change power docking device for a rolling main machine, the rolling main machine 100 is installed on a bottom machine base 200, and a power mechanism 300 is provided on the bottom machine base 200 on the left side of the rolling main machine 100, and the power docking device 400 is provided between the power output shaft of the power mechanism 300 and the power input shaft of the rolling main machine 100, including a left half clutch 401 and a right half clutch 402 coaxially arranged on the left and right, the left half clutch 401 and the right half clutch 402 are tooth-engaged with each other in the mating surface, the right half clutch 402 is fixedly installed on the power input shaft of the rolling main machine 100, the left half clutch 401 is installed on the power output shaft of the power mechanism 300, and the power mechanism 300 is provided with a docking drive device that cooperates with the left half clutch 401, and the docking drive device drives the left half clutch 401 to slide along the axis of the power output shaft to engage or disengage the right half clutch 402.

[0021] The left clutch 401 and the right clutch 402 are connected by tooth-engaging, which belongs to the prior art and will not be described in detail. The left clutch 401 is connected to the power output shaft by a key, and the left clutch 401 can slide horizontally along the key.

[0022] See also Figure 3 and Figure 4The docking drive device includes a mounting support 403 and a docking drive cylinder 404, the cylinder body of the docking drive cylinder 404 is hinged on the mounting support 403, the telescopic end of the docking drive cylinder 404 is hinged with a docking swing arm 405, the middle part of the docking swing arm 405 is hinged on the mounting support 403, the bottom end of the docking swing arm 405 is provided with a docking plug arm 406, the surface of the left half clutch 401 is provided with a docking ring groove 407, and the end of the docking plug arm 406 is correspondingly inserted into the docking ring groove 407.

[0023] See also Figure 5 The docking arm 406 includes two docking pins 408 arranged at the front and rear ends. The two docking pins 408 span the left half clutch 401, and the bottom ends extend to the front and rear sides of the docking ring groove 407 respectively. A rotating bearing 409 is also rotatably installed at the bottom end of the docking pin 408. The outer peripheral surface of the rotating bearing 409 abuts against the side surface of the docking ring groove 407. The rotating bearing 409 extends out of the docking ring groove 407 to cooperate with the docking ring groove 407 to achieve the purpose of pushing the left half clutch 401 without affecting the rotation of the left half clutch 401.

[0024] See also Figure 6 and Figure 7 The mounting support 403 is provided with an articulated seat which is articulated with the docking swing arm 405 .

[0025] The power mechanism 300 includes an electric motor, an output end of the electric motor is connected to a reducer, and the power output shaft is connected to the output end of the reducer.

[0026] The power mechanism 300 is provided with a distance sensor 410, and the outer peripheral surface of the right half clutch 402 is provided with a positioning block 411 corresponding to the distance sensor, and the outer peripheral surface of the left half clutch 401 is provided with a shielding ring plate 412, and the surface of the shielding ring plate 412 is provided with a light-transmitting hole 413, and the light-transmitting hole 413 is located between the distance sensor 410 and the positioning block 411, and the signal of the distance sensor 410 can reach the surface of the positioning block 411 through the light-transmitting hole 413. When the left half clutch 401 and the right half clutch 402 are in the engaged state, the light-transmitting hole 413 corresponds to the position of the positioning block 411, and when the signal of the distance sensor 410 passes through the light-transmitting hole 413 but does not reach the positioning baffle, it means that the position of the right half clutch 402 does not correspond to the position of the left half clutch 401. The distance sensor 410 detects the distance between the positioning block 411 and transmits the distance signal to the controller, and determines whether the position of the positioning block 411 corresponds to the position according to the distance value.

[0027] The rolling main machine 100 includes a rolling bottom plate and rolling devices arranged on the rolling bottom plate. Power is transmitted between multiple rolling devices through gears, and the power input shaft of one rolling device serves as the power input shaft of the rolling main machine 100 .

[0028] The working principle of this embodiment is:

[0029] When the roller pressing main machine 100 needs to be replaced, first the power mechanism 300 stops, the left half clutch 401 and the right half clutch 402 stop, and when they stop, the signal of the distance sensor 410 just reaches the positioning block 411 through the light-transmitting hole 413, and at this time, the position of the left half clutch 401 and the right half clutch 402 defines it as the docking position; then the docking drive cylinder 404 extends, driving the docking swing arm 405 to swing, and the docking pin 408 drives the left half clutch 401 to slide horizontally in the direction away from the right half clutch 402, so that the left half clutch 401 and the right half clutch 402 are disengaged, and then the roller pressing main machine 100 is moved away by a crane, and the roller pressing main machine 100 to be replaced is replaced and installed on the bottom machine base 200; generally, the angle of the replaced right half clutch 402 will not change, and it just corresponds to the docking position of the left half clutch 401, that is, the distance sensor 410 just reaches the positioning block 411 through the light-transmitting hole 413, and at this time, the automatic docking is directly started, and the docking drive cylinder 404 directly The left clutch 401 is retracted, driving the docking swing arm 405 to swing, and the docking pin 408 drives the left clutch 401 to slide toward the right clutch 402, so that the left clutch 401 and the right clutch 402 are docked and engaged, that is, the power automatic docking is automatically completed, and the docking drive cylinder 404 is locked in this position to ensure that the left clutch 401 does not shift in position. After the power is started, the left clutch 401 and the right clutch 402 rotate to achieve power transmission. When the left clutch 401 rotates, the rotating bearing 409 can rotate adaptively to reduce the friction between the two, and at the same time, the left clutch 401 can be limited; but if the angle of the right clutch 402 changes, the distance sensor 410 will not detect the positioning block 411 through the light-transmitting hole 413 at this time. Therefore, before docking, the worker needs to manually rotate the right clutch 402 to adjust the position of the positioning block 411 so that it corresponds to the distance sensor 410. When the distance sensor 410 detects the positioning block 411, the automatic docking program is started.

[0030] The utility model can be applied to the automatic power docking after the roller pressing main machine 100 is replaced, which is achieved by tooth matching, and the clutch achieves docking and locking by sliding, and no longer needs to be fixed by bolts. The docking method is simple and the effect is higher.
