[0027] Refer to Figures 1 - 3As shown in the figure, the present application proposes a knurling assembly 100. The knurling assembly 100 includes a support plate 10, a base lifting mechanism 20, and a chip removal mechanism. The base lifting mechanism 20 is movably arranged on the support plate 10 and is used for placing a motor; the chip removal mechanism is arranged below the base lifting mechanism 20, and the chip removal mechanism includes a docking member 31 and a vacuum generator (not shown in the drawings); a chip removal channel 313 is arranged between both ends of the docking member 31. Wherein, one end of the docking member 31 is used for docking with the rotating shaft of the rotor in the motor to receive the chips shed from the rotating shaft, and the other end is connected to the vacuum generator.

[0028] In the technical solution of the present application, the support plate 10 serves as the basic platform of the knurling assembly 100, stably supporting other components to ensure its stability and reliability. The base lifting mechanism 20 is movably arranged on the support plate 10, and its purpose is to place the motor and drive the motor to move up and down, so that the rotating shaft in the motor follows the movement to realize the knurling operation on the predetermined position of the rotating shaft.

[0029] Among them, the base lifting mechanism 20 positions the working position of the rotating shaft in the motor. When the chip removal mechanism is arranged below the base lifting mechanism 20, and the docking member 31 and the vacuum generator are further arranged, the chips shed during the knurling operation of the rotating shaft can be collected and removed.

[0030] It can be understood that the base lifting mechanism 20 includes a base 210. A placement hole for placing the motor is arranged on the base 210, and a through hole for the rotating shaft to pass through is arranged below the placement hole. When the motor is placed on the base 210, its rotating shaft will pass through the through hole and extend below the base 210; and the present application is to perform knurling operation on the rotating shaft below the base 210. In this way, the working process of the chip removal mechanism is as follows:

[0031] During the knurling operation, under the action of the knurling tool, the chips fall onto the docking member 31. Then the vacuum generator starts the suction operation, and the negative pressure suction generated by the vacuum generator is transmitted to the docking member 31 through the chip removal channel 313, sucking the chips on the docking member 31 and transporting them to the designated collection device. Thus, the purpose of chip cleaning is achieved, greatly improving the production efficiency and the cleanliness of the working environment.

[0032] Among them, the docking member 31 is designed to be able to maintain a certain distance and angle from the rotating shaft, so as to effectively receive the falling chips and prevent them from splashing into the surrounding environment.

[0033] Refer to Figure 2 As shown in the figure, in some embodiments, the docking member 31 is a docking rod 311 arranged to rotate. One end of the docking rod 311 is provided with a docking nozzle 312 for cooperating with the rotating shaft. The docking nozzle 312 is used for the insertion of the rotating shaft and chip collection.

[0034] In this embodiment, the further arrangement of the docking member 31 can provide for the insertion of the shaft. It is worth noting that the insertion of the shaft is limited to a short distance of the end of the shaft, and the area to be knurled on the shaft is still exposed to the docking nozzle 312. In this way, the docking nozzle 312 is as close to the area to be knurled as possible, achieving a good debris receiving effect and avoiding the knurling operation of the shaft.

[0035] The purpose of the docking rod 311 being rotatably arranged is that when the knurling operation is performed, the rotating shaft rotates, and at this time, the docking rod 311 can rotate along with the rotating shaft, thereby preventing the fixed docking rod 311 from affecting the rotation of the rotating shaft.

[0036] Furthermore, a docking port facing upward and with an inner diameter gradually increasing is formed in the docking nozzle 312, the inner side of the docking port is a smooth inner wall and the cross-sectional shape of each part in the docking port is circular.

[0037] It can be understood that the docking interface is formed similar to a conical funnel, which can play a good guiding role for the rotating shaft. When the rotating shaft is inserted into the docking nozzle 312, the conical design can guide the rotating shaft to enter the docking position smoothly, reducing the friction and collision caused by improper alignment. Moreover, the gradually increasing inner diameter also means that there is a larger receiving space, which can accommodate more debris. During the knurling operation, as the debris is continuously generated and falls, the debris will naturally accumulate at the lower part of the docking interface, thereby improving the efficiency of debris collection.

[0038] Further providing a smooth inner wall helps the debris to flow smoothly under the action of negative pressure suction, thereby reducing the possibility of debris accumulation and clogging inside the docking nozzle 312, and improving the operating efficiency of the entire chip removal mechanism. The circular cross-section also means that the docking nozzle 312 can adapt to shafts of different diameters, thereby enhancing the versatility and adaptability of the knurl assembly 100.

[0039] Among them, a standard equipment mode is that the filling shape of the docking port is a cone shape. Or more preferably, the filling shape of the docking port is similar to a trumpet shape with a curved surface.

[0040] See also Figure 2 As shown, in some embodiments, the chip removal mechanism further includes a mounting seat 33 that is lifted and lowered, a docking rod 311 is disposed through the mounting seat 33 , and a bearing 34 is disposed between the docking rod 311 and the mounting seat 33 .

[0041] In this embodiment, the mounting base 33 with a lifting setting allows the height of the docking rod 311 to be adjusted according to actual needs, which can ensure that the docking rod 311 can always maintain an appropriate docking distance and angle with the rotating shaft, thereby improving the efficiency of debris collection. And a bearing 34 is arranged between the docking rod 311 and the mounting base 33, which can significantly reduce the friction between the two, make the docking rod 311 rotate more smoothly, reduce energy loss and wear, and extend the service life of the docking rod 311 and the mounting base 33.

[0042] Furthermore, the relative position between the material seat and the mounting base 33 is fixed. In this design case, when the motor is placed on the mounting base 33, it can be assembled and inserted into the docking nozzle 312. Then, keeping the relative position unchanged, the material seat and the mounting base 33 move up and down synchronously to drive the rotating shaft to reach the predetermined position. Among them, the material seat and the mounting base 33 can be arranged on the same set of lifting drive mechanisms.

[0043] Refer to Figure 1 and Figure 3 As shown, in some embodiments, the knurling assembly 100 further includes a first knurling mechanism 41 and a second knurling mechanism 42 arranged on the support plate 10. The first knurling mechanism 41 and the second knurling mechanism 42 are arranged opposite to each other and are used to cooperate to perform the knurling operation on the rotating shaft in the motor placed on the material seat lifting mechanism 20.

[0044] In this embodiment, the first knurling mechanism 41 and the second knurling mechanism 42 are the main components for realizing the positioning and knurling operation of the rotating shaft. Among them, the first knurling mechanism 41 and the second knurling mechanism 42 are arranged opposite to each other, so that the knurling processing can be carried out on different parts of the rotating shaft at the same time. This parallel processing method greatly shortens the knurling operation time and improves the production efficiency.

[0045] Further, both the first knurling mechanism 41 and the second knurling mechanism 42 include knurling tools and corresponding adjusting devices (not shown in the drawings). The adjusting devices are used to adjust the distance between the two groups of knurling tools. In this way, it can adapt to the motor rotating shafts of different sizes and improve the applicability. The spoilers of the first knurling mechanism 41 and the second knurling mechanism 42, as well as the corresponding knurling tools and adjusting devices are the existing settings of this application, such as the cooperation of the driving device setting a horizontal click, a horizontal sifan and a horizontal sliding seat. The specific structure will not be elaborated here.

[0046] Refer to Figure 1 and Figure 3As shown, in some embodiments, the knurling assembly 100 further includes a pressing mechanism 50 disposed above the base lifting mechanism 20. The pressing mechanism 50 is used to press against the upper surface of the motor to stabilize the state of the motor. Among them, stabilizing the state of the motor means preventing the motor from being mixed and ensuring the precise processing of the knurling operation. The pressing mechanism 50 can be an existing structural design including a liftable pressing block, which will not be elaborated here.

[0047] The present application also provides a knurling device, which includes the knurling assembly 100 as described above.

[0048] This knurling device also adopts all the technical solutions of all embodiments of the above-mentioned knurling assembly 100. Therefore, it has at least all the beneficial effects brought by the technical solutions of the above embodiments, which will not be elaborated one by one here.

Any equivalent structural transformation made by using the content of the specification and drawings of the present application under the overall concept of the present application, or direct / indirect application in other related technical fields is included in the scope of protection of the present application.
