Description

Technical Field

[0001] This utility model relates to the field of motor production equipment technology, and in particular to automated motor rotor assembly equipment. Background Technology

[0002] Bearings are required on the rotor shaft of the motor to support its rotation and bear all radial and axial loads. The assembly of the shaft and bearings plays a crucial role in the normal operation of the rotor. The assembly process involves several steps: fixing the rotor and its shaft in place, pressing in the bearing, flipping the rotor, re-fixing the rotor and its shaft, and pressing in the bearing again. This assembly process is relatively complex and inefficient. Furthermore, repositioning the rotor after flipping it requires high precision in the equipment.

[0003] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this disclosure, and therefore may include information that does not constitute prior art known to those skilled in the art. Utility Model Content

[0009] The first station is equipped with a fixing block, the upper surface of which has a horizontal fixing groove; the fixing block includes a first part and a second part; a vertically arranged gap is left between the first part and the second part;

[0010] A suction cup is disposed on one side of the fixing block along the length of the fixing slot; a clearance hole is opened on the surface of the suction cup near the fixing block, and a telescopic cylinder is disposed on the side of the suction cup away from the fixing block;

[0011] The left gripper and the fixing block are in the same vertical plane; two suction cups are provided; the two suction cups are located on opposite sides of the first workstation.

[0012] Along the sliding direction of the transverse slide plate, two fixing blocks are provided in the first station.

[0013] Along the sliding direction of the transverse slide plate, two left grippers are provided on the left support; the distance between adjacent left grippers is equal to the distance between adjacent fixed blocks in the first workstation.

[0014] Along the sliding direction of the transverse slide plate, a feeding rack is provided at one end of the first station; a feeding slot is opened on the upper surface of the feeding rack and a gap is provided; the feeding slot is parallel to the fixed slot; the distance between the feeding slot and the nearest fixed slot is equal to the distance between the adjacent left grippers.

[0015] Along the sliding direction of the transverse slide plate, a second station and a right support are also provided; the fixed block is also provided in the second station; a right gripper is provided on the right support; the right support is connected to the right gripper through another translation component.

[0016] The left support and a suction cup are arranged on the opposite side of the first station; the right support and another suction cup are arranged on the opposite side of the second station.

[0017] Along the sliding direction of the transverse slide plate, two fixing blocks are provided in the second station.

[0018] Along the direction from the first workstation to the second workstation, three right grippers are sequentially arranged on the right support; the distance between the first right gripper and the second right gripper is equal to the distance between two adjacent fixed blocks between the first workstation and the second workstation; the distance between the second right gripper and the third right gripper is equal to the distance between two adjacent fixed blocks within the second workstation.

[0019] Along the sliding direction of the transverse slide plate, a feeding rack is provided on the side of the second station away from the first station; a feeding slot is formed on the upper surface of the feeding rack and a gap is provided; the feeding slot is parallel to the fixed slot; the distance between the feeding slot and the nearest fixed slot is equal to the distance between the second right gripper and the third right gripper.

[0020] The horizontal sliding plate is connected to the left or right support, and the vertical sliding plate is connected to the horizontal sliding plate via a slide cylinder.

[0021] The left gripper is a cylinder gripper.

[0022] The beneficial technical effects of this utility model are as follows:

[0023] (1) The automated motor rotor assembly equipment of this utility model restricts the vertical movement of the motor rotor through a fixed slot and restricts the horizontal movement of the motor rotor through the gap between the first and second parts. The fixed slot and the gap fit completely fix the motor rotor. The planes facing each other of the first and second parts can contact the rotor body to quickly position the motor rotor. The surfaces of the first and second parts facing away from each other can contact the bearing to quickly position the bearing during subsequent press-fitting. In addition, the left gripper is connected to the left bracket through the vertical and horizontal sliding plates to move freely in the vertical plane. By adjusting the motor rotor to be parallel to the fixed position on the fixed block when it is in the loading and unloading positions, the left gripper can automatically load and unload the motor rotor. At the same time, two suction cups are symmetrically arranged to press-fit the bearings at both ends of the motor rotor without flipping the motor rotor, simplifying the press-fitting steps between the motor rotor and the bearing and improving the press-fitting efficiency between the motor rotor and the bearing.

[0024] (2) Furthermore, two fixing blocks are respectively provided in the first and second workstations. One fixing block is used for pressing the bearing, and the other fixing block is used for temporarily storing the motor rotor. This is to facilitate quickly clearing the processing position and pressing the bearing on the next shaft, thereby improving the pressing efficiency.

[0025] (3) Further, the distance between adjacent left grippers is equal to the distance between adjacent fixed blocks in the first station, and equal to the distance between the loading slot and the nearest fixed slot. This allows one left gripper to load or remove the pressed motor rotor while the other left gripper can remove the pressed motor rotor or place the pressed motor rotor on an empty fixed block, thus improving the working efficiency of the left grippers.

[0033] Figure 1 A front view structural schematic diagram of an automated motor rotor assembly apparatus according to an embodiment of the present disclosure is shown. Figure 2 A top view of an automated motor rotor assembly apparatus according to an embodiment of the present disclosure is shown. Figure 3 A partially enlarged view of point A is shown of an automated motor rotor assembly apparatus according to an embodiment of this disclosure. Please refer to... Figure 1 , Figure 2 and Figure 3The automated motor rotor assembly equipment includes a left support 3 and a left gripper 32. A translation component 31 is provided between the left gripper 32 and the left support 3. The translation component 31 includes a horizontal slide plate 311 and a vertical slide plate 312 connecting the horizontal slide plate 311. The left gripper 32 is connected to the left support 3 via the vertical slide plate 312 and the horizontal slide plate 311, allowing it to move freely in a vertical plane. By adjusting the motor rotor to be parallel to the fixed position on the fixed block 11 when it is in the loading and unloading positions, the left gripper 32 can automatically load and unload the motor. In the first station 1, a fixed block 11 is provided, and a fixing slot 12 is horizontally formed on the upper surface of the fixed block 11. The fixed block 11 includes a first part 13 and a second part 14. A vertically set gap is left between the first part 13 and the second part 14. The fixing slot 12 restricts the movement of the motor rotor in the vertical direction, and the gap between the first part 13 and the second part 14 restricts the movement of the motor rotor in the horizontal direction. The fixing slot 12 and the gap fit completely fix the motor rotor. The opposing planes of the first part 13 and the second part 14 can contact the rotor body 8 to quickly position the motor rotor. The opposing surfaces of the first part 13 and the second part 14 can contact the bearing 82 to quickly position the bearing 82 during subsequent press-fitting. A suction cup 5 is disposed on one side of the fixing block 11 along the length of the fixing groove 12. A clearance hole is formed on the surface of the suction cup 5 near the fixing block 11, and a telescopic cylinder 51 is disposed on the side of the suction cup 5 away from the fixing block 11. In this embodiment, the suction cup 5 can be an electro-permanent magnet suction cup 5 clamp to hold and fix the bearing 82. When press-fitting the bearing 82, the rotating shaft 81 extends into the clearance hole to press the bearing 82 on the suction cup 5 into a preset position on the rotating shaft 81.

[0034] The left gripper 32 and the fixing block 11 are in the same vertical plane. Two suction cups 5 are provided. The two suction cups 5 are located on opposite sides of the first station 1. The bearings 82 at both ends of the motor rotor are press-fitted without flipping the motor rotor, simplifying the pressing process between the motor rotor and the bearings 82 and improving the pressing efficiency between the motor rotor and the bearings 82.

[0035] Please refer to Figure 1 and Figure 2 Along the sliding direction of the transverse slide plate 311, two fixing blocks 11 are set in the first station 1. One fixing block 11 is used for pressing the bearing 82, and the other fixing block 11 is used to temporarily store the motor rotor. This allows for quick clearing of the processing position to press the bearing 82 on the next rotating shaft 81, improving pressing efficiency.

[0036] Preferably, two left grippers 32 are provided on the left support 3 along the sliding direction of the transverse slide plate 311. The distance between adjacent left grippers 32 is equal to the distance between adjacent fixed blocks 11 within the first station 1. This allows one left gripper 32 to place the motor rotor to be pressed onto one fixed block 11, while the other left gripper 32 can place the already pressed motor rotor onto another fixed block 11, thus improving the working efficiency of the left grippers 32.

[0037] More preferably, a loading rack 6 is provided at one end of the first station 1 along the sliding direction of the transverse slide plate 311. A loading slot 61 with a gap is formed on the upper surface of the loading rack 6. The loading slot 61 is parallel to the fixed slot 12. The distance between the loading slot 61 and the nearest fixed slot 12 is equal to the distance between adjacent left grippers 32. This allows the first left gripper 32 to hold the motor rotor on the loading rack 6 while the other left gripper 32 can hold the nearly press-fitted motor rotor on the fixed block 11 at the pressing position. This improves the working efficiency of the left grippers 32.

[0038] Please refer to Figure 1 and Figure 2 Along the sliding direction of the transverse slide plate 311, a second station 2 and a right support 4 are also provided. A fixing block 11 is also provided in the second station 2. A right gripper 41 is provided on the right support 4. The right support 4 is connected to the right gripper 41 via another translation component 31. The pressing steps of the two bearings 82 on the same motor rotor are split and performed at different stations, and are transferred respectively via the left gripper 32 and the right gripper 41. A left support 3 and a suction cup 5 are provided on the opposite side of the first station 1. A right support 4 and another suction cup 5 are provided on the opposite side of the second station 2.

[0039] Preferably, two fixing blocks 11 are provided in the second station 2 along the sliding direction of the transverse slide plate 311. One fixing block 11 is used for pressing the bearing 82, and the other fixing block 11 is used for temporarily storing the motor rotor. This allows for quick clearing of the processing position to press the bearing 82 on the next rotating shaft 81, improving pressing efficiency.

[0040] More preferably, three right grippers 41 are sequentially arranged on the right support 4 along the direction from the first station 1 to the second station 2. The distance between the first right gripper 41 and the second right gripper 41 is equal to the distance between two adjacent fixed blocks 11 between the first station 1 and the second station 2. The distance between the second right gripper 41 and the third right gripper 41 is equal to the distance between two adjacent fixed blocks 11 in the second station 2. This allows the first right gripper 41 to grip a motor rotor with one bearing 82 pressed onto a fixed block 11 in the first station 1, the second right gripper 41 to grip a motor rotor with two bearings 82 pressed onto a fixed block 11 in the second station 2, and the third right gripper 41 to grip a motor rotor on a fixed block 11 in the second station 1. In addition, when the first right gripper 41 places the gripped motor rotor on the first fixed block 11, the second right gripper 41 and the third right gripper 41 can place the gripped motor rotor on the second fixed block 11 and the unloading rack 7, respectively. Improve the working efficiency of the right gripper 41.

[0041] In some embodiments, along the sliding direction of the transverse slide plate 311, a feeding rack 7 is provided on the side of the second station 2 away from the first station 1. A feeding slot 71 with a gap is formed on the upper surface of the feeding rack 7. The feeding slot 71 is parallel to the fixed slot 12. The distance between the feeding slot 71 and the nearest fixed slot 12 is equal to the distance between the second right gripper 41 and the third right gripper 41. The feeding slot 71 is for the rotating shaft 81 to be engaged, and the gap is for the rotor body 8 to be engaged.

[0042] Please refer to Figure 1 and Figure 2 The horizontal slide plate 311 is connected to the left support 3 or the right support 4, and the vertical slide plate 312 is connected to the horizontal slide plate 311, respectively, via a slide cylinder 313. The slide cylinder 313 integrates a linear guide, buffer limit, and magnetic ring detection functions, and this integrated structure saves space. In some embodiments, the left gripper 32 is a cylinder gripper, which facilitates automated control.

[0043] The specific workflow of this utility model is as follows:

[0044] The operator or the feeding device places the motor rotor to be assembled on the feeding rack 6, with the rotating shaft 81 inserted into the feeding slot 61 and the rotor body 8 extending into the gap of the feeding rack 6. The slide cylinder 313 drives the left gripper 32 to move. After the left gripper 32 clamps the motor rotor, the slide cylinder 313 drives the left gripper 32 to move above the first fixed block 11 in the first station 1. The left gripper 32 releases, and the motor rotor is inserted into the fixed block 11. The telescopic cylinder 51 drives the suction cup 5 to move, pressing the bearing 82 onto the rotating shaft 81. The slide cylinder 313 drives the left gripper 32 to move the motor rotor to another fixed block 11 in the first station 1. Then, the slide cylinder 313 on the right bracket 4 drives the right gripper 41 to move, placing the motor rotor sequentially onto the two fixed blocks 11 in the second station 2. When the motor rotor is placed on the first fixed block 11 in the second station 2, the second telescopic cylinder 51 drives the second suction cup 5 to move, pressing the second bearing 82 onto the rotating shaft 81. At this time, both rotating shafts 81 on the motor shaft 81 are installed. Finally, the right gripper 41 moves under the drive of the slide cylinder 313, placing the pressed motor rotor onto the unloading rack 7, completing the processing of the motor rotor.

[0045] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0046] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
