Description

TECHNICAL FIELD

[0001] Embodiments of the present disclosure relate to the technical field of motor processing equipment, in particular, to a device for installing a rotor shaft and a rotor frame. BACKGROUND

[0002] A motor refers to an electromagnetic device that realizes electric energy conversion or transmission according to electromagnetic induction law.

[0003] The main function of a motor is to generate driving torque, which serves as a power source for electric appliances or various machines. It can be said that a motor is an indispensable power device in modern society.

[0004] A motor includes a rotor and a rotating shaft. During the manufacturing process of the motor, the rotating shaft needs to be inserted into the center of the rotor to complete the process of the rotor driving the rotating shaft to move.

[0005] A motor shaft installation machine is disclosed in Chinese Patent No. CN204366385U, which is used to assemble a rotating shaft on a product. The motor shaft installation machine includes a positioning mechanism for positioning the product, a feeding mechanism for conveying the rotating shaft, and an assembly mechanism cooperating with the feeding mechanism. The feeding mechanism includes a storage assembly for storing the rotating shaft and a feeding assembly for conveying the rotating shaft to the assembly mechanism. The assembly mechanism includes a movable plate and a clamp fixedly arranged on the movable plate. An adjusting hole is formed in the movable plate. The assembly mechanism further includes a correction member cooperating with the adjusting hole. The correction member includes a correction cylinder, an adjusting rod connected to the correction cylinder, and a guide seat for guiding the adjusting rod. The adjusting rod is provided with a head at one end close to the movable plate. The cross-sectional diameter of the head is adapted to the diameter of the adjusting hole and is larger than the cross-sectional diameter of the adjusting rod. The above-mentioned motor shaft installation machine realizes accurate positioning of the product through the positioning mechanism. The feeding mechanism can automatically convey the rotating shaft to the assembly mechanism. At the same time, the assembly mechanism realizes the effect of accurately assembling the rotating shaft through the cooperation of the correction member and the adjusting hole of the movable plate. Compared with the traditional manual operation of simple tools to realize the assembly of the rotating shaft, the motor shaft installation machine improves the assembly efficiency and assembly accuracy. At the same time, the motor shaft installation machine has a high degree of automation, thereby saving labor costs.

[0037] like Figures 1-4 As shown, it illustrates an apparatus for mounting a rotor shaft and a rotor frame according to an embodiment of the present disclosure, comprising:

[0038] The frame 1, the conveyor belt 2, and the platform 3 are arranged in the frame 1 and the platform 3 is arranged on the surface of the frame 1.

[0039] The support frame 4 and the rotor shaft insertion assembly 5 are provided on the support frame 3 and the platform 3, respectively.

[0040] Rotor frame positioning assembly 6 is installed on the frame 1 and the platform 3;

[0041] The rotor shaft insertion assembly 5 includes a feed rack 5-1, which is fixed on the surface of the frame 3. Both ends of the feed rack 5-1 have circular openings 5-2. A telescopic hydraulic cylinder 5-3 is provided on the surface of the frame 3. The output end of the telescopic hydraulic cylinder 5-3 is located inside the circular opening 5-2. A drive motor 5-4 is fixed on the surface of the frame 3. The output end of the drive motor 5-4 is connected to a sleeve 5-5. A through cavity 5-6 is provided inside the sleeve 5-5. A telescopic cylinder 5-7 is provided inside the through cavity 5-6. A clamping block 5-8 is provided at the output end of the telescopic cylinder 5-7.

[0042] In some examples, to achieve the effect of automatically feeding the rotor shaft and changing its angle, a rotor shaft insertion assembly 5 is designed. A feed rack 5-1 is fixed on the surface of the frame 3. The feed rack 5-1 has an inclined angle, allowing the rotor shaft to be inserted laterally into the feed rack 5-1. Circular openings 5-2 are provided on both sides of the feed rack 5-1. A telescopic hydraulic cylinder 5-3 is provided on the surface of the frame 3. The output end of the telescopic hydraulic cylinder 5-3 is located in the circular opening 5-2. By telescopically extending or retracting, the rotor shaft inside the feed rack 5-1 can be pushed outward. The frame 3 is fixed with... There is a drive motor 5-4 and a sleeve 5-5. The movable rotor shaft can be inserted into the sleeve 5-5. The sleeve 5-5 has a through cavity 5-6. The through cavity 5-6 is equipped with a telescopic cylinder 5-7 and a clamping block 5-8. The telescopic cylinder 5-7 can push the clamping block 5-8 to fix the rotor shaft in the sleeve 5-5. Then, the sleeve 5-5 can be controlled to rotate 90° so that the rotor shaft is vertically downward. The top of the upright frame 4 is equipped with a vertical hydraulic cylinder 5-9. The vertical hydraulic cylinder 5-9 can push the rotor shaft downward to insert it into the rotor frame.

[0043] like Figures 1-4 As shown, this embodiment proposes a rotor frame positioning assembly 6, which includes a pair of fixing columns 6-1, the fixing columns 6-1 being fixed on the frame 1, each fixing column 6-1 being equipped with a positioning cylinder 6-2, the output end of the positioning cylinder 6-2 being provided with a positioning frame 6-3, the surface of the frame 3 being provided with a fixing groove 6-4, the surface of the frame 1 being provided with a notch 6-5, the side surface of the frame 3 being provided with a second cylinder 6-6, the output end of the second cylinder 6-6 being provided with a support block 6-7, the inner side of the fixing groove 6-4 being provided with a rectangular opening 6-8, the surface of the frame 1 being provided with a push cylinder 6-9, the output end of the push cylinder 6-9 being provided with a push block 6-10.

[0044] In some examples, a rotor frame positioning assembly 6 is designed to achieve the positioning of the rotor frame and the outward pushing effect. Two fixed posts 6-1 are set on the frame 1, positioned at 90° to each other. Positioning cylinders 6-2 and positioning frames 6-3 are installed on each fixed post 6-1. The rotor frame conveyed on the conveyor belt 2 can be positioned by the positioning frames 6-3. A fixing groove 6-4 is provided inside the frame 3, allowing the rotor frame to be pushed into the fixing groove 6-4. A notch 6-5 is provided on the surface of the frame 1 for insertion. A second cylinder 6-6 and a support block 6-7 are provided on the other side of the frame 3, passing through the rotor shaft. The support block 6-7 is located at the fixed groove 6-4. After the rotor shaft and rotor frame are installed, the support block 6-7 can be controlled to move backward to open the fixed groove 6-4. A rectangular opening 6-8 is provided inside the fixed groove 6-4. A push cylinder 6-9 and a push block 6-10 are provided on the surface of the frame 1. The push block 6-10 is located inside the rectangular opening 6-8. The push cylinder 6-9 can control the push block 6-10 to push the rotor frame outward for unloading.

[0045] For example, such as Figure 1As shown, the positioning frame 6-3 has an arc-shaped transition structure, and the surface curvature of the positioning frame 6-3 matches the surface curvature of the rotor frame.

[0046] In some examples, the curved structure allows for a perfect fit with the rotor frame, resulting in more precise positioning.

[0047] For example, such as Figure 1 As shown, a U-shaped structure is formed between the fixing groove 6-4 and the side surface of the support block 6-7.

[0048] In some examples, the rotor frame can be positioned on the same axis as the vertical hydraulic cylinders 5-9 using a U-shaped structure.

[0049] For example, such as Figure 1 As shown, the surface of the feed rack 5-1 has a notch 7.

[0050] In some examples, a notch 7 is provided to facilitate observation of the number of rotor shafts inside the feed rack 5-1.

[0051] For example, such as Figure 4 As shown, the sleeve 5-5 and the circular opening 5-2 are located on the same axis, and the inner diameter of the sleeve 5-5 is the same as the inner diameter of the circular opening 5-2.

[0052] In some examples, the rotor shaft can be accurately inserted into the sleeve 5-5 by using the same axis position.

[0053] For example, such as Figure 3 As shown, the upper surface of the conveyor belt 2 is slightly higher than the surface of the frame 1.

[0054] In some examples, the rotor frame is not restricted at the bottom as it moves from the conveyor belt 2 into the frame 1 due to the slightly higher plane height.

[0055] When processing is required, the rotor shaft is placed into the feed rack 5-1, and then the rotor frame is placed onto the conveyor belt 2. The conveyor belt 2 is started to transport the rotor frame. The rotor frame is positioned by the positioning frame 6-3. Then, the positioning cylinder 6-2 is started to push the rotor frame into the fixing groove 6-4. The telescopic hydraulic cylinder 5-3 is started to push the rotor frame into the sleeve 5-5. Then, the telescopic cylinder 5-7 is started to fix the rotor shaft by the clamping block 5-8. Then, the drive motor 5-4 is started to control the sleeve 5-5 to rotate 90°. The clamping block 5-8 is released, and the rotor shaft slides down and is inserted into the rotor frame. Then, the vertical hydraulic cylinder 5-9 is started to insert the rotor shaft into the rotor frame. The second cylinder 6-6 is started to pull the support block 6-7 backward. Finally, the ejection cylinder 6-9 is started to push the rotor frame outward by the pushing block 6-10.

[0056] It should be noted that the above embodiments are only used to illustrate the technical solutions of this disclosure and are not intended to limit it. Although this disclosure has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this disclosure without departing from the spirit and scope of the technical solutions of this disclosure, and all such modifications and substitutions should be covered within the scope of the claims of this disclosure.
