[0027] The present application will be further described in conjunction with the accompanying drawings and specific embodiments.

[0028] The present application relates to a kind of optical axis rotor into shaft device, it is to solve the problem of the device that there is no special optical axis rotor at present into shaft, the present application's into shaft device not only into shaft precision is high, can also adapt to the rotor of multiple different sizes and carry out into shaft operation, in addition, the device of the present application can also adapt to the production streamline of optical axis rotor, improve production efficiency.

[0029] Specifically, as shown in Figure 1 The optical axis rotor into shaft device of the present application includes: Servo press 401; Shaft feeding mechanism, the shaft feeding mechanism includes shaft feeder 4022, and the shaft feeder 4022 is located below the output end of servo press; Rack 403, rack 403 is provided with turntable 404, and the turntable 404 is provided with a plurality of stations, at least including feeding station and into shaft station, and the turntable 404 at the feeding station and into shaft station is penetrated by opening along the axial direction; Sub-assembly clamping mechanism 405 is connected on each station of turntable 404, and is used for clamping rotor core and end plate.

[0030] Specifically, servo press 401 is used to drive the shaft in shaft feeder 4022 to move downwards into the opening of rotor core and end plate to complete into shaft operation;Shaft feeder 4022 is used as the temporary storage device of shaft, when into shaft operation is needed, servo press 401 drives the shaft in shaft feeder 4022 to enter into the opening of rotor core and end plate from shaft feeder 4022; Sub-assembly clamping mechanism 405 is used to store heated rotor core and end plate, to ensure that the core and end plate do not move relative to each other in each station, and keep the mechanical skew does not change.

[0031] Rack 403 is used to support the entire into shaft device, and turntable 404 is used to drive sub-assembly clamping mechanism 405 in each station to flow through;In the embodiment, the turntable 404 rotates counterclockwise, and the sub-assembly clamping mechanism 405 flows through in the feeding station and into shaft station in turn, and reciprocating cycle.

[0032] In fact, a plurality of supports are further arranged between the rotating disc 404 and the rack 403, for guaranteeing the stable rotation of the rotating disc 404 and avoiding the overturning of the rotating disc 404 due to uneven force. The lower end of the support is fixedly connected with the rack 403, and the upper end is slidingly connected with a ball bearing, which is in direct contact with the rotating disc 404, thereby providing a smooth rotating environment for the rotating disc 404.

[0033] In some embodiments, the above-mentioned shaft feeding mechanism is optimized, as shown in Figure 1 The shaft feeding mechanism further comprises a shaft sliding table 4021, which is located below the servo press 401, and the shaft feeder 4022 is slidingly connected with the shaft sliding table 4021.

[0034] When different types of rotors need to be subjected to shafting operation, the position of the shaft feeder 4022 on the shaft sliding table 4021 can be adjusted to adapt to different types of rotors for shafting operation. At the same time, by adjusting the position of the shaft feeder 4022 on the shaft sliding table 4021, the interference between the mechanical hand and the sub-assembly clamping mechanism 405 on the rotating disc 404 during the shaft feeding of the mechanical hand can be avoided.

[0035] In some embodiments, the above-mentioned rotating disc 404 is optimized, as shown in Figure 1 A detection station is further arranged between the feeding station and the shafting station of the rotating disc 404, for detecting the mechanical skew of the rotor core and the end plate. A detection device 408 is arranged beside the detection station, and the lower end of the detection device 408 is fixedly connected with the rack 403.

[0036] In actual work, the mechanical skew of the rotor core and the end plate is detected before the rotor shafting, which can ensure that the relative position of the rotor core and the end plate remains consistent, thereby greatly improving the accuracy of the rotor shafting.

[0037] Optionally, the detection device 408 in the embodiment is a profilometer.

[0038] In some embodiments, the above-mentioned rotating disc 404 is optimized, as shown in Figure 1 A discharging station is further arranged between the shafting station and the feeding station of the rotating disc 404.

[0039] In actual work, the separate arrangement of the discharging station can solve the interference between the mechanical hand and the shaft feeder 4022 during the discharging of the rotor. At the same time, the separate arrangement of the discharging station is also conducive to improving the shafting efficiency of the rotor. The feeding station is dedicated to the feeding of the rotor core and the end plate, the shafting station is dedicated to the shafting of the rotor, and the discharging station is dedicated to the discharging of the rotor after the shafting. The stations do not interfere with each other and each performs its own function.

[0040] Optionally, the rotating disc 404 rotates counterclockwise in the embodiment, and the sub-assembly clamping mechanism 405 sequentially flows through the feeding station, the detection station, the shaft-feeding station, and the discharging station, and reciprocally circulates.

[0041] In some embodiments, the sub-assembly clamping mechanism 405 is optimized as shown in Figure 2 The sub-assembly clamping mechanism 405 includes a bottom plate 4051, a base tooling 4052, and a swing arm cylinder 4053. The base tooling 4052 is connected with the bottom plate 4051. The lower end of the swing arm cylinder 4053 is a fixed end, which is connected with the bottom plate 4051 and located at the two ends of the base tooling 4052. The upper end is an adjustable clamp 40531, which can rotate in the horizontal direction with the fixed end of the swing arm cylinder 4053 as the axis. The bottom plate 4051 and the base tooling 4052 are penetrated by an opening along the axial direction, which is coaxial with the opening on the rotating disc 404.

[0042] Specifically, the bottom plate 4051 supports the connection between the base tooling 4052 and the swing arm cylinder 4053. The base tooling 4052 is used to store the heated rotor core and end plate. The swing arm cylinder 4053 is used to clamp the heated rotor core and end plate, and keep the mechanical skew of the rotor core and end plate from changing.

[0043] When the heated rotor core and end plate need to be placed on the sub-assembly clamping mechanism 405, the clamps 40531 of the two swing arm cylinders 4053 are rotated to an open state, then the heated rotor core and end plate are placed on the base tooling 4052, and then the clamps 40531 of the two swing arm cylinders 4053 are rotated to a closed state. The swing arm cylinder 4053 is adjusted so that the clamps 40531 move downward until the rotor core and end plate are clamped. When the shaft-fed rotor needs to be moved away from the sub-assembly clamping mechanism 405, the swing arm cylinder 4053 is adjusted so that the clamps 40531 move upward and loosen the shaft-fed rotor. Then the clamps 40531 of the two swing arm cylinders 4053 are rotated to an open state. Finally, the robot moves the rotor away from the base tooling 4052.

[0044] In some embodiments, the clamp 40531 is optimized as shown in Figure 2 The clamp 40531 is used to fix one end of the rotor core and end plate, and the clamp is made of high-temperature-resistant heat-insulating material.

[0045] In actual work, since the rotor core and end plate are preheated, their temperature is relatively high. The clamp, as a component directly contacting the rotor core and end plate, needs to be high-temperature-resistant. At the same time, in order to avoid the high temperature of the rotor core and end plate affecting the work of the swing arm cylinder 405, the clamp needs to be heat-insulating. Therefore, the clamp of the embodiment is made of high-temperature-resistant heat-insulating material.

[0046] In some embodiments, the swing arm cylinder 4053 is further optimized as shown in Figure 2 The swing arm cylinder 4053 further includes a limiting arm 40532, one end of which is fixedly connected to the fixed end of the swing arm cylinder 4053, and the other end is arranged perpendicularly to the clamp 40531, for guiding and limiting the movement of the clamp 40531.

[0047] In actual work, in order to avoid the horizontal shaking of the clamp 40531 when moving up and down from affecting the mechanical skewing of the rotor core and the end plate, it is necessary to limit the movement of the clamp 40531 in the horizontal direction; one end of the limiting arm 40532 is fixedly connected to the fixed end of the swing arm cylinder 4053, and the other end is arranged perpendicularly to the clamp 40531, so that the clamp 40531 can only move vertically along the guide of the limiting arm 40532 when moving up and down, avoiding movement in the horizontal direction and affecting the mechanical skewing of the rotor core and the end plate.

[0048] Optionally, as shown in Figure 2 The swing arm cylinder 4053 further includes a temperature sensing device 4054 connected to the bottom plate 4051 for monitoring the temperature of the rotor core and the end plate.

[0049] In some embodiments, the base tooling 4052 is optimized as shown in Figure 3 The base tooling 4052 includes a first pad layer 40521 and a second pad layer 40522, the first pad layer 40521 being a metal layer for directly contacting the rotor core and the end plate; the second pad layer 40522 being a rubber pad layer made of high-temperature-resistant heat-insulating material.

[0050] Specifically, the first pad layer 40521 is a pad layer that directly contacts the rotor core and the end plate, and is made of metal that has certain strength and is resistant to high temperature; the second pad layer 49522 is a buffer layer connected to the bottom plate 4051 of the sub-assembly clamping mechanism 405, and is made of high-temperature-resistant heat-insulating rubber; the first pad layer 40521 and the second pad layer 49522 can be designed according to the specific size of the rotor core and the end plate, so that each size of the rotor core and the end plate has a corresponding size of the special base tooling 4052.

[0051] In some embodiments, the feeding station is optimized as shown in Figure 1 The feeding station is provided with a feeding positioning shaft 406 coaxially arranged with the opening of the turntable 404, and the feeding positioning shaft 406 can move up and down relative to the opening of the turntable 404.

[0052] In fact, a servo mechanism is arranged below the feeding positioning shaft 406, which is used to drive the feeding positioning shaft 406 to move up and down; In actual work, the feeding positioning shaft 406 is used to ensure that the rotor core and the end plate have no relative movement during feeding. Specifically, after the two swing arm cylinders 4053 of the sub-assembly clamping mechanism 405 are rotated to the open state, the servo mechanism drives the feeding positioning shaft 406 to move upward and pass through the opening of the bottom plate 4051 and the base tooling 4052, so as to align the openings of the rotor core and the end plate with the feeding positioning shaft 406 and place them on the base tooling 4052. After the two swing arm cylinders 4053 of the sub-assembly clamping mechanism 405 clamp the rotor core and the end plate, the servo mechanism drives the feeding positioning shaft 406 to move downward and disengage from the opening of the turntable 404.

[0053] In some embodiments, the above-mentioned shaft entering station is optimized, as shown in Figure 1 The shaft entering station is provided with a positioning mandrel 407. The positioning mandrel 407 is coaxially arranged with the opening of the turntable 404 on the shaft entering station and can slide up and down relative to the turntable 404. Optionally, the upper end of the positioning mandrel 407 in this embodiment is a tapered structure, which is complementary to the concave tapered groove at the lower end of the rotor shaft.

[0054] In fact, a servo mechanism is arranged below the positioning mandrel 407, which is used to drive the feeding positioning shaft 406 to move up and down. In actual work, the positioning mandrel 407 is used to ensure the accuracy of the shaft entering of the optical shaft rotor during the shaft entering operation. Specifically, after the sub-assembly clamping mechanism 405 is turned to the shaft entering station, the servo mechanism drives the positioning mandrel 407 to move upward, so that the positioning mandrel 407 passes through the openings of the turntable 404, the bottom plate 4051, the base tooling 4052, the rotor core and the end plate. The servo press 401 is started to drive the rotor shaft on the shaft feeder 4022 to move downward until the tapered groove at the lower end of the rotor shaft coincides with the tapered structure at the upper end of the positioning mandrel 407. The servo press 401 further drives the rotor shaft on the shaft feeder 4022 to move downward, while the servo mechanism drives the positioning mandrel 407 to move downward synchronously to guide the rotor shaft to slowly press into the openings of the rotor core and the end plate. After the rotor shaft enters the shaft, the servo mechanism drives the positioning mandrel 407 to further move downward and disengage from the openings of the rotor core and the end plate.

[0055] In some embodiments, the above-mentioned gantry 403 is optimized, as shown in Figure 1 The gantry 403 is provided with a base tooling storage area 4031 for storing base toolings 4052 of different models.

[0056] When the shafting operation needs to be performed on different types of rotors: the base tooling 4052 on the sub-assembly clamping mechanism 405 of the feeding station, the detection station, the shafting station, and the discharging station is replaced and placed on the base tooling storage area 4031 on the rack 403; the base tooling 4052 corresponding to different types of rotors on the base tooling storage area 4031 is replaced to the feeding station, the detection station, the shafting station, and the discharging station; at the same time, the position of the shaft feeder 4022 on the shaft sliding table 4021 is adjusted until the rotor shaft of the shaft feeder 4022 is coaxial with the opening of the base tooling 4052 and the bottom plate 4051 of the sub-assembly clamping mechanism 405 after the type replacement.

[0057] The optical axis rotor shafting method of the present application specifically comprises: Placing the rotor core and the end plate: the two swing arm air cylinders 4053 of the sub-assembly clamping mechanism 405 are rotated to the open state; the feeding positioning shaft 406 is driven to move upward and pass through the opening of the bottom plate 4051 and the base tooling 4052; the opening of the rotor core and the end plate is aligned with the feeding positioning shaft 406 and placed on the base tooling 4052; the two swing arm air cylinders 4053 of the sub-assembly clamping mechanism 405 are rotated to the closed state, the clamp at the upper end of the swing arm air cylinder 4053 is adjusted to move downward along the limiting wall of the swing arm air cylinder 4053 and clamp the rotor core and the end plate; the feeding positioning shaft 406 is driven to move downward and disengage from the opening of the turntable 404; Detecting the mechanical skew of the rotor: the turntable 404 is rotated to make the rotor core and the end plate on the sub-assembly clamping mechanism 405 of the feeding station move to the detection station; the detection device 408 detects whether the mechanical skew of the rotor meets the requirements; Rotor shafting: the turntable 404 is rotated to make the rotor core and the end plate on the sub-assembly clamping mechanism 405 of the detection station move to the shafting station; the positioning mandrel 407 is driven to move upward along the mandrel sliding table 4072, so that the positioning mandrel 407 passes through the openings of the turntable 404, the bottom plate 4051, the base tooling 4052, the rotor core, and the end plate; the servo press 401 is started to drive the shaft on the shaft feeder 4022 to move downward until the tapered groove at the lower end of the rotor shaft coincides with the tapered structure at the upper end of the positioning mandrel 407; the servo press 401 further drives the rotor shaft on the shaft feeder 4022 to move downward, while the positioning mandrel 407 moves downward synchronously to guide the rotor shaft to slowly press into the opening of the rotor core and the end plate; after the rotor shaft is shafted, the positioning mandrel 407 further moves downward and disengages from the opening of the rotor core and the end plate; Rotor blanking: rotate the turntable 404, so that the rotor core and end plate on the subassembly clamping mechanism 405 of the shaft inlet station are turned to the blanking station, adjust the clamp 40531 on the upper end of the swing arm cylinder 4053, make the clamp 40531 move upward along the limiting wall 40532 and loosen the rotor after entering the shaft; rotate the two swing arm cylinders 4053 to the open state, and move the rotor away from the base tooling 4052 by the mechanical hand.
