[0021] like Figure 1As shown, the rotary telescopic integrated motor includes an end cover, a stator 200, a rotor 300, and a rotor shaft 400. The end cover is rectangular and has a first through hole; three end covers are provided. The stator 200 is rectangular and has a second through hole. The stator 200 is positioned between two adjacent end covers, and the second through hole and the first through hole are connected. Two stators are provided. The rotor 300 is cylindrical and has a shaft hole. The rotor 300 is positioned within the second through hole, and there is a preset distance between the outer wall of the rotor 300 and the inner wall of the stator 200. The rotor shaft 400 is rod-shaped and passes through the first through hole, the second through hole, and the shaft hole. The rotor shaft 400 is a splined shaft with ball screw threads, suitable for cooperating with the rotor 300 to achieve axial rotation and movement in the length direction. The rotor 300 includes a first rotor 310 and a second rotor 320, which are respectively disposed in two second through holes. A predetermined distance exists between the first rotor 310 and the second rotor 320. The inner wall of the first rotor 310 is configured as a spline nut, and the outer surface of the rotor shaft 400 connecting to the inner wall of the first rotor 310 is provided with a spline that matches the spline nut. The inner wall of the second rotor 320 is configured as a ball nut, and the outer surface of the rotor shaft 400 connecting to the inner wall of the second rotor 320 is provided with a ball screw thread that matches the ball nut.
[0022] Specifically, the structure of the rotary telescopic integrated motor includes an end cover, a stator 200, a rotor 300, and a rotor shaft 400. First, the stator 200 and rotor 300 are set to generate magnetic force between them, enabling the rotor 300 and rotor shaft 400 to rotate. Therefore, the rotor 300 is located inside the stator 200, and the rotor shaft 400 is located inside the rotor 300. Thus, a second through hole is provided on the stator 200. Because the rotor shaft 400 needs to move in the length direction and rotate around its axis, two rotors 300 are required to cooperate. Therefore, two rotors 300 are needed, and further, two stators 200 are required. To enable the sub-shaft 400 to move along its length and rotate around its axis, the rotor shaft 400 is configured as a splined shaft with ball screw threads. Since two rotors 300 are required, the rotor 300 includes a first rotor 310 and a second rotor 320. To adapt to the rotor shaft 400, the inner wall of the first rotor 310 is configured with a splined nut, and the outer surface of the rotor shaft 400 connecting to the inner wall of the first rotor 310 has splines that match the splined nut. The inner wall of the second rotor 320 is configured with a ball screw nut, and the outer surface of the rotor shaft 400 connecting to the inner wall of the second rotor 320 has ball screw threads that match the ball screw nut. It should be noted that the splined nut inside the inner wall of the first rotor 310 drives the rotor shaft 400 to rotate during device operation. The ball screw nut inside the shaft hole of the second rotor 320 allows the rotor shaft 400 to move linearly back and forth when the second rotor 320 rotates. When the first rotor 310 and the second rotor 320 operate at the same speed, the rotor shaft 400 only rotates and does not extend or retract. When the first rotor 310 operates alone, the rotor shaft 400 only extends or retracts and does not rotate. When the two rotors 300 operate at different speeds or directions, the rotor shaft 400 will rotate and extend or retract.
[0023] In one possible implementation, a plurality of grooves are uniformly formed on the outer walls of the first rotor 320 and the second rotor 320, and the grooves are formed along the length direction of the first rotor 310 and the second rotor 320; protrusions corresponding to the grooves are formed on the inner wall of the stator 200. The stator 200 includes a first stator 210 and a second stator 220.
[0024] Specifically, such as Figure 1As shown, in order to make the stator 200 and rotor 300 fit together more closely, the stator 200 includes a first stator 210 and a second stator 220. The second rotor 310 is disposed inside the first stator 210, and the second rotor 320 is disposed inside the second stator. Grooves are formed on the outer walls of the first rotor 310 and the second rotor 320. The grooves are evenly distributed along the length of the outer walls of the first rotor 310 and the second rotor 320. The interiors of the first stator 210 and the first stator 220 are provided with protrusions that match the grooves. This arrangement makes the stator 200 and rotor 300 more compact.
[0025] In one possible implementation, the end caps include a first end cap 110, a second end cap 120, and a third end cap 130. The first end cap 110 and the second end cap 120 are located at opposite ends of the rotor shaft 400, respectively, and the second end cap 120 is disposed between the first rotor 310 and the second rotor 320. A first stator 210 is disposed between the first end cap 110 and the second end cap 120, and a second stator 220 is disposed between the second end cap 120 and the third end cap 130.
[0026] Specifically, such as Figure 1 As shown, a more specific connection between the end cover and the stator 200 is as follows: 100 includes a first end cover 110, a second end cover 120, and a third end cover 130. The first end cover 110 and the second end cover 120 are located at both ends of the rotor shaft 400, respectively. The third end cover 130 is disposed between the first rotor 310 and the second rotor 320, thus better separating the first rotor 310 and the second rotor 320. The first stator 210 is disposed between the first end cover 110 and the second end cover 120, and the second stator 220 is disposed between the second end cover 120 and the third end cover 130.
[0027] In one possible implementation, an encoder 500 is also included. The encoder 500 is a circular plate structure with a third through hole on its upper part. Two encoders 500 are provided, and the two encoders 500 are respectively located at the outer ends of the first end cover 110 and the second end cover 120.
[0028] Specifically, such as Figure 1 As shown, the encoder 500 is configured to detect the movements of the first rotor 310 and the second rotor 320, and further provide feedback on the movement and position of the rotor shaft 400. Therefore, the encoder 500 is also electrically connected to an external client.
[0029] In one possible implementation, an outer cover 600 is also included. The outer cover 600 has a rectangular structure and a fourth through hole. The inner end of the outer cover 600 has a second groove that matches the shape of the encoder 500. Two outer covers 600 are provided, and the two outer covers 600 are respectively provided at the outer ends of the two encoders 500.
[0030] Specifically, such as Figure 1 As shown, an outer cover 600 is provided in order to fix the encoder 500. Since there are two encoders, there are also two outer covers. The two outer covers 600 are respectively set on the outer ends of the two encoders, and a second groove corresponding to the shape and size of the encoder 500 is opened on the inner side of the outer cover 600. The encoder 500 is located inside the second groove. The two outer covers 600 are respectively connected to the first end cover 110 and the third end cover 130. The rotor shaft 400 passes through the fourth through hole to facilitate connection with the external removal device.
[0031] In one possible implementation, the four apex corners of the inner end of the first end cover 110 are provided with first extensions 111, which are L-shaped trapezoidal structures. The structure of the second end cover 120 is the same as that of the first end cover 110. The inner and outer ends of the third end cover 130 are both provided with second extensions 131, which are the same as those of the first extensions 111. Furthermore, the four apex corners of the first stator 210 and the second stator 220 are provided with clearance grooves, the shape of which matches the shape of the first extensions 111.
[0032] Specifically, such as Figure 1 As shown, to make the overall structure of the device more complete, the four apex corners of the inner end of the first end cover 110 are provided with first extensions 111, which are L-shaped trapezoidal structures. The structure of the second end cover 120 is the same as that of the first end cover 110. The inner and outer ends of the third end cover 130 are both provided with second extensions 131, which are the same as those of the first extensions 111. Furthermore, the four apex corners of the first stator 210 and the second stator 220 are provided with clearance grooves, the shape of which matches the shape of the first extensions 111. Both the first extensions 111 and the second extensions 131 are disposed in the clearance grooves, making the entire structure more compact.
[0033] In one possible implementation, a housing 700 is also included. The housing 700 is a hollow cuboid structure with openings at both ends. The end caps, stator 200, rotor 300 and encoder 500 are all disposed inside the housing 700. The outer cover 600 is connected to both ends of the housing 700.
[0034] Specifically, in order to better protect the entire device, a housing 700 is provided. In order to better accommodate the end cover, stator 200, rotor 300, rotor shaft 400 and encoder 500, the housing 700 is a hollow cuboid structure with open ends. The outer cover 600 is connected to the two ends of the housing 700, and the outer cover 600 and the housing 700 form an accommodating space.
[0035] Through the above-mentioned configuration, this application enables the overall structure to be more compact. At the same time, the cooperation between the rotor shaft and the rotor allows the rotor shaft to perform a certain movement in the length direction and also to rotate around the axis. By connecting the rotor shaft to the external extraction device, the external extraction device can perform the movement and rotation. This solves the technical problem that the equipment on the market uses two motors to perform this action, which results in a larger size of the equipment and a higher cost.
[0036] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the scope disclosed in the present invention, based on the technical solution and concept of the present utility model, should be included within the protection scope of the present utility model.
