Description

Technical Field

[0001] This utility model relates to the field of micro motor assembly technology, and in particular to a device for rapid insertion of motor rotor into housing. Background Technology

[0002] In the production process of micro motors, if manual assembly is used, when the operator inserts the rotor into the motor housing, an unavoidable problem arises: because the housing is pre-installed with tile-shaped magnets, which have strong magnetism, they exert a significant attraction on the rotor. This can easily cause the rotor to deviate during insertion, making it easy for the iron core or bearing components on the rotor to collide with the tile-shaped magnets and deform. This directly leads to a significant increase in the product defect rate.

[0003] In addition, the magnetic attraction of the tile-shaped magnets can interfere with the rotor installation process. Operators need to expend more effort to overcome this magnetic influence and carefully adjust the rotor's position and angle to insert it accurately. This undoubtedly prolongs the installation time of a single rotor, significantly reduces the overall assembly speed, and adversely affects production efficiency.

[0004] Therefore, it is necessary to develop a device for rapid rotor insertion into the housing of an electric motor to solve the above-mentioned problems. Utility Model Content

The front mounting plate has a limiting hole through which the clamping head passes. The rear end of the clamping head is fixed to the first slider. The front end of the clamping head has multiple sets of elastic grippers. The inner sides of the multiple sets of elastic grippers form a clamping hole, and the outer sides of the elastic grippers have a pressing slope. The Y-axis drive assembly is fixed to the worktable. The housing platform is fixed to the power output end of the Y-axis drive assembly and corresponds to the front side of the rotor clamping assembly. The housing platform is made of magnetic metal, and an arc-shaped placement groove is provided above the housing platform.

[0008] Further description of the present invention: The rotor clamping assembly also includes an adjusting bolt and a limiting plate. The adjusting bolt is threadedly connected to the front mounting plate, and the limiting plate is fixed at the front end of the adjusting bolt and corresponds to the rear side of the housing platform.

[0009] Further description of this utility model: A limiting ring is also provided on the outer shell platform, and the limiting ring is fixedly set at the front end or rear end of the arc-shaped placement groove.

[0010] Further description of the present invention: The Y-axis drive assembly includes a second Y-axis cylinder, a Y-axis slide, a Y-axis slide plate, and a second slider. The second Y-axis cylinder and the Y-axis slide are both fixed above the worktable. The Y-axis slide plate is fixed to the power output end of the second Y-axis cylinder. The second slider is fixed below the Y-axis slide plate and is slidably connected to the Y-axis slide. The outer shell platform is fixed above the Y-axis slide plate.

[0011] Further description of this utility model: It also includes a bearing rotating assembly and a bearing adhesive application assembly, both of which are fixed on the worktable and correspond to the left and right sides of the clamping head, respectively.

[0012] Further description of this utility model: The bearing rotation assembly includes a first mounting base, a first X-axis slide, a first X-axis cylinder, a first X-axis slider, a first adjusting seat, and a drive rod. The first mounting base is fixed on the worktable. The first X-axis slide is fixed on the first mounting base and its position is adjustable in the front-rear direction. The first X-axis cylinder is fixed at one end of the first X-axis slide. The first X-axis slider is fixed at the power output end of the first X-axis cylinder and is slidably connected to the first X-axis slide. The first adjusting seat is fixed above the first X-axis slider. The drive rod is fixed on the first adjusting seat and its position is adjustable in the left-right direction.

The contour of the arc-shaped placement groove matches the outer diameter of the motor housing. Since the motor housing is pre-installed with a tile-shaped magnet, it can be fixed to the housing platform by magnetic force. Then, the equipment is started automatically by pressing the start button on the equipment. The first Y-axis cylinder drives the first slider to slide backward on the connecting slide rail, thereby driving the clamping head to move backward. After the extrusion slope on the elastic jaw touches the limiting hole, as the clamping head continues to move backward, the limiting hole drives each set of elastic jaws to contract towards the clamping hole through the extrusion slope, thereby clamping the rear end of the rotor shaft, thus fixing the rotor in a horizontal position. Then, the Y-axis drive assembly drives the housing platform to move backward, so that the rear end of the rotor shaft is accurately inserted into the through hole of the motor housing. Subsequently, the rotor clamping assembly and the Y-axis drive assembly are reset in sequence, and the motor housing with the rotor can be removed from the housing platform. The advantages of this design are: the rotor is fixed in a horizontal position and will not be misaligned due to the attraction of the tile-shaped magnet, so it can be accurately inserted into the motor housing. This not only avoids damage to the rotor and improves the product qualification rate, but also improves the efficiency of rotor insertion into the housing. Attached Figure Description

[0023] The present invention will be further described below with reference to the accompanying drawings:

[0024] like Figures 1 to 6 As shown, a device for rapid rotor insertion into a housing includes a worktable 1, a rotor clamping assembly 2, a Y-axis drive assembly 3, and a housing platform 4. The rotor clamping assembly 2 includes a front mounting plate 21, a rear mounting plate 22, a connecting slide rail 23, a first Y-axis cylinder 24, a first slider 25, and a clamping head 26. The front mounting plate 21 and the rear mounting plate 22 are both fixed above the worktable 1. The front and rear ends of the connecting slide rail 23 are respectively fixed to the front mounting plate 21 and the rear mounting plate 22. The first Y-axis cylinder 24 is fixed to the rear mounting plate 22. The first slider 25 is fixed to the power output end of the first Y-axis cylinder 24 and is connected to the connecting slide rail 26. The rail 23 is slidably connected. The front mounting plate 21 is provided with a limiting hole 211. The clamping head 26 passes through the limiting hole 211. The rear end of the clamping head 26 is fixed on the first slider 25. The front end of the clamping head 26 is provided with multiple sets of elastic claws 261. The inner sides of the multiple sets of elastic claws 261 surround to form a clamping hole 262. The outer side of the elastic claws 261 is provided with a pressing slope 263. The Y-axis drive assembly 3 is fixed on the worktable 1. The outer shell platform 4 is fixed on the power output end of the Y-axis drive assembly 3 and corresponds to the front side of the rotor clamping assembly. The outer shell platform 4 is made of magnetic metal. An arc-shaped placement groove 41 is provided on the top of the outer shell platform 4.

[0025] This design is for quickly assembling a motor rotor into a motor housing. First, the end of the rotor shaft is inserted into the clamping hole 262. Then, the motor housing is placed on the arc-shaped placement groove 41, the contour of which matches the outer diameter of the motor housing. Since the motor housing is pre-installed with a tile-shaped magnet, it can be fixed to the housing platform 4 by magnetic force. Next, the device is started automatically by pressing the start button on the device. The first Y-axis cylinder 24 drives the first slider 25 to slide backward on the connecting slide rail 23, thereby driving the clamping head 26 to move backward, and the elastic gripper 261... After the extrusion ramp 263 touches the limiting hole 211, as the clamping head 26 continues to move backward, the limiting hole 211, driven by the extrusion ramp 263, causes each set of elastic grippers 261 to retract towards the clamping hole 262, thereby clamping the rear end of the rotor shaft and fixing the rotor in a horizontal position. Then, the Y-axis drive assembly 3 drives the housing platform 4 to move backward, precisely inserting the rear end of the rotor shaft into the through hole of the motor housing. Subsequently, the rotor clamping assembly 2 and the Y-axis drive assembly 3 reset sequentially, allowing the motor housing containing the rotor to be removed from the housing platform 4. The advantages of this design are: the rotor is fixed in a horizontal position and will not be misaligned due to the attraction of the tile-shaped magnet, enabling precise insertion into the motor housing. This not only avoids rotor damage and improves product yield but also increases the efficiency of rotor insertion into the housing.

[0026] The rotor clamping assembly 2 also includes an adjusting bolt 27 and a limiting plate 28. The adjusting bolt 27 is threadedly connected to the front mounting plate 21, and the limiting plate 28 is fixed at the front end of the adjusting bolt 27 and corresponds to the rear side of the housing platform 4.

[0027] By adjusting the bolt 27, the distance between the limiting plate 28 and the front mounting plate 21 can be adjusted. When the Y-axis drive assembly 3 drives the housing platform 4 to move backward, the stroke of the housing platform 4 is limited, thereby adapting to the flexible adjustment of motor housings of different lengths.

[0028] The outer casing platform 4 is also provided with a limiting ring 42, which is fixedly installed at the front end or rear end of the arc-shaped placement groove 41. The limiting ring 42 can limit the end of the motor casing when placing it, improving the efficiency of placing the motor casing. Depending on the different motor casing structures and production requirements, the limiting ring 42 can be installed at the front end of the arc-shaped placement groove 41 to limit the front end of the motor casing, or at the rear end of the arc-shaped placement groove 41 to limit the rear end of the motor casing.

[0029] The Y-axis drive assembly 3 includes a second Y-axis cylinder 31, a Y-axis slide 32, a Y-axis slide plate 33, and a second slider 34. The second Y-axis cylinder 31 and the Y-axis slide plate 32 are both fixed above the worktable 1. The Y-axis slide plate 33 is fixed to the power output end of the second Y-axis cylinder 31. The second slider 34 is fixed below the Y-axis slide plate 33 and is slidably connected to the Y-axis slide plate 32. The outer shell platform 4 is fixed above the Y-axis slide plate 33.

[0030] The second Y-axis cylinder 31 drives the Y-axis slide plate 33 to move back and forth, and the Y-axis slide plate 33 slides smoothly on the Y-axis slide table 32 via the second slider 34.

[0031] This design also includes a bearing rotation assembly 5 and a bearing adhesive application assembly 6, both of which are fixed on the worktable 1 and correspond to the left and right sides of the clamping head 26, respectively.

[0032] For certain models of motor rotors, bearings are pre-installed on the front shaft. The rotor needs to be inserted into the motor housing, and the bearings are assembled in the holes in the motor housing. The outer circumference of the bearing needs to be fixedly assembled to the motor housing. Therefore, before inserting into the motor housing, the outer surface of the bearing is first coated with glue by the bearing glue application assembly 6. The bearing rotation assembly 5 is used to drive the bearing to rotate one revolution on the rotor shaft, so that the bearing glue application assembly 6 can apply glue to the entire outer circumference of the bearing. The bearing is fixed in the holes in the motor housing by the glue.

[0033] The bearing rotation assembly 5 includes a first mounting base 51, a first X-axis slide 52, a first X-axis cylinder 53, a first X-axis slider 54, a first adjusting seat 55, and a drive rod 56. The first mounting base 51 is fixed on the worktable 1. The first X-axis slide 52 is fixed on the first mounting base 51 and its position is adjustable in the front-to-back direction. The first X-axis cylinder 53 is fixed at one end of the first X-axis slide 52. The first X-axis slider 54 is fixed at the power output end of the first X-axis cylinder 53 and is slidably connected to the first X-axis slide 52. The first adjusting seat 55 is fixed above the first X-axis slider 54. The drive rod 56 is fixed on the first adjusting seat 55 and its position is adjustable in the left-to-right direction. The drive rod 56 is made of elastic material.

[0034] The first X-axis cylinder 53 drives the first X-axis slider 54 to move to the right on the first X-axis slide table 52, so that the upper end face of the drive rod 56 contacts the bottom of the bearing. As the drive rod 56 continues to move to the right, the bearing rotates at a certain angle, which generally requires the drive bearing to rotate one revolution.

[0035] The bearing adhesive application assembly 6 includes a second mounting base 61, a second X-axis slide 62, a second X-axis cylinder 63, a second X-axis slider 64, a second adjusting seat 65, and an adhesive application head 66. The second mounting base 61 is fixed on the worktable 1. The second X-axis slide 62 is fixed on the second mounting base 61 and its angle is adjustable. The second X-axis cylinder 63 is fixed at one end of the second X-axis slide 62. The second X-axis slider 64 is fixed at the power output end of the second X-axis cylinder 63 and is slidably connected to the second X-axis slide 62. The second adjusting seat 65 is fixed above the second X-axis slider 64. The adhesive application head 66 is fixed on the second adjusting seat 65 and its position is adjustable in the left and right directions. The coating end of the adhesive application head 66 faces the clamping head 26.

[0036] The second X-axis cylinder 63 drives the second X-axis slider 64 to move on the second X-axis slide 62, thereby bringing the coating end of the coating head 66 close to the bearing. Adhesive is continuously squeezed out from the coating head 66, and under the drive of the bearing rotating assembly 5, adhesive is applied to the entire outer periphery of the bearing.

[0037] The above does not limit the technical scope of this utility model. Any modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of this utility model shall still fall within the scope of the technical solution of this utility model.
