Description

Technical Field

[0001] This utility model relates to the field of motor production equipment technology, specifically to a motor auxiliary assembly device for a motor production line. Background Art

[0002] The motor production line uses automated equipment and systems to tightly connect all aspects of the motor production process. Automated operation greatly reduces the time and labor intensity of manual operation, and can achieve higher production speeds compared to traditional manual production methods.

[0003] A search revealed a Chinese patent with publication number CN217824664U that discloses an auxiliary assembly device for a motor rotor. This device uses a cylinder to push two clamping plates to move simultaneously toward the surface of the stator until they are in contact, so that the stator can achieve a self-centering state and also clamp the stator. By controlling the motor to drive the lead screw to rotate, the device can move the mounting plate vertically downward along the axis of the lead screw. At the same time, the rotor held by the chuck on one side of the mounting plate can be vertically assembled into the stator, ultimately achieving the purpose of automatic and quick assembly of the stator and rotor.

[0004] However, in existing technologies, the stator and rotor are usually installed together, which easily leads to contact between the stator and rotor during installation, causing scratches and wear on the surface of the silicon steel sheets, affecting the conduction and distribution of the magnetic field. In order to solve the problem of easy contact and collision between the stator and rotor during installation in the prior art, this application proposes to set up a split buffer assembly between the stator and rotor to avoid direct contact and collision between the stator and rotor, thereby avoiding damage during installation and improving the quality of assembly. Therefore, a new solution is needed to solve this problem. Utility Model Content

[0005] The existing technology mentioned above has shortcomings and defects, such as the tendency for contact to occur between the stator and rotor during installation, which can cause scratches and wear on the surface of the silicon steel sheets, affecting the conduction and distribution of the magnetic field and causing problems in improving the quality of assembly.

[0006] The present invention discloses an auxiliary assembly device for a motor production line, comprising a mounting plate, a clamping assembly on the upper surface of the mounting plate, a fixing plate above the mounting plate, a lifting assembly between the fixing plate and the mounting plate, an air pipe on the fixing plate, and an airbag on the air pipe.

[0007] Furthermore, the clamping assembly includes a bidirectional threaded rod, which is rotatably mounted on the mounting plate. Sliders are provided at both ends of the bidirectional threaded rod, and the sliders are threadedly connected to the bidirectional threaded rod. An arc-shaped plate is provided on the side of the two sliders that are close to each other.

[0008] Furthermore, a connecting shaft is mounted on the arc-shaped plate, a guide groove is provided on the slider, the connecting shaft passes through the guide groove, and a fixing nut is provided on the connecting shaft, the fixing nut being threadedly connected to the connecting shaft.

[0009] Furthermore, the lifting assembly includes a sliding plate, which is slidably mounted on the mounting plate. A lifting plate is provided at the upper end of the sliding plate, and a one-way screw is provided between the lifting plate and the sliding plate. The one-way screw is rotatably mounted on the sliding plate and is threadedly connected to the lifting plate.

[0010] Furthermore, a drive rod is provided at the lower end of the one-way screw, the drive rod is rotatably mounted on the mounting plate, a bevel gear one is slidably mounted on the drive rod, the bevel gear one is rotatably mounted on the slide plate, and a bevel gear two is installed at the lower end of the one-way screw, the bevel gear one and the bevel gear two mesh and transmit power.

[0011] Furthermore, a second bidirectional screw is provided below the drive rod, the second bidirectional screw is rotatably mounted on the mounting plate, and the second bidirectional screw is threadedly connected to the slide plate.

[0012] Furthermore, the fixing plate and the lifting plate are connected by fixing bolts, and one end of the air pipe is set in a "T" shape.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0014] 1. This utility model is equipped with components such as a fixing plate, an airbag, and an air pipe. During operation, the clamping assembly fixes the outer shell containing the stator. Then, the lifting assembly controls the fixing plate to move downward, inserting the airbag and air pipe into the inside of the stator. The air pipe inflates the airbag, causing it to collide with the rotor. The rotor is then installed inside. When the rotor tilts, the airbag buffers and blocks the movement, thus avoiding direct contact between the stator and rotor, preventing damage, and improving assembly quality.

[0015] 2. This utility model is equipped with a connecting shaft, a fixing nut, and a double-headed screw. During operation, the rotation of the double-headed screw is controlled, which drives the two slide plates to move relative to each other, thereby adjusting the distance between the two double-headed screws. This makes it suitable for processing parts of different sizes. Through the cooperation between the connecting shaft and the fixing nut, the position of the arc-shaped plate on the slider can be adjusted. Attached Figure Description

[0022] The following illustrations will reveal several embodiments of the present invention. For clarity, many physical details will be described in the following description. However, it should be understood that these physical details should not be used to limit the present invention. That is, in some embodiments of the present invention, these physical details are not essential. Furthermore, for the sake of simplicity, some conventional structures and components will be shown in a simple schematic manner in the illustrations.

[0023] Please see Figure 1 , Figure 4 As shown, the motor auxiliary assembly device for motor production line of this utility model includes a mounting plate 1. The equipment is installed on the production line through the mounting plate 1 and cooperates with the robot on the production line. A clamping component 2 is provided on the upper end face of the mounting plate 1. A fixing plate 3 is provided above the mounting plate 1. A lifting component 6 is provided between the fixing plate 3 and the mounting plate 1. An air pipe 4 is provided on the fixing plate 3. The air pipe 4 is connected to an external air inflator through a hose. An air bag 5 is provided on the air pipe 4. By inflating the air bag 5 with gas, the air bag 5 is expanded. By placing the air bag 5 between the installed stator and rotor, direct contact between the stator and rotor is avoided, so that there is a gap between the air bag 5 and the stator and rotor.

[0024] like Figure 3As shown, the clamping assembly 2 includes a bidirectional threaded rod 201, which is rotatably mounted on the mounting plate 1. A servo motor is provided at the power end of the bidirectional threaded rod 201, and sliders 202 are provided at both ends of the bidirectional threaded rod 201. The sliders 202 are threadedly connected to the bidirectional threaded rod 201. An arc-shaped plate 203 is provided on the side where the two sliders 202 are close to each other. The bidirectional threaded rod 201 is rotated by the servo motor, which drives the two sliders 202 to move relative to each other. The sliders 202 drive the arc-shaped plate 203 to move accordingly. When the two arc-shaped plates 203 are close to each other, the part is clamped; conversely, when the two arc-shaped plates 203 are far apart, the part is released from fixation.

[0025] In this embodiment, a connecting shaft 204 is installed on the arc plate 203, and a guide groove 206 is provided on the slider 202. The connecting shaft 204 passes through the guide groove 206, and a fixing nut 205 is provided on the connecting shaft 204. The fixing nut 205 is threadedly connected to the connecting shaft 204. By driving the fixing nut 205 to rotate, the squeezing and fixing of the slider 202 is released. Then, the arc plate 203 can be driven to move on the slider 202, thereby adjusting the height of the arc plate 203. After adjusting to the preset position, the fixing nut 205 is driven to rotate in the opposite direction to fix it again.

[0026] See Figure 2 As shown, the lifting assembly 6 includes a sliding plate 601, which is slidably mounted on the mounting plate 1. A lifting plate 602 is provided at the upper end of the sliding plate 601. A one-way screw 603 is provided between the lifting plate 602 and the sliding plate 601. The one-way screw 603 is rotatably mounted on the sliding plate 601 and is threadedly connected to the lifting plate 602. Controlling the rotation of the one-way screw 603 drives the lifting plate 602 to move on the sliding plate 601, thereby adjusting the height of the lifting plate 602.

[0027] In this embodiment, a drive rod 604 is provided at the lower end of the one-way screw 603, and a servo motor is provided at the power end of the drive rod 604. The drive rod 604 is rotatably mounted on the mounting plate 1, and a bevel gear 605 is slidably mounted on the drive rod 604. The bevel gear 605 is rotatably mounted on the slide plate 601, and a bevel gear 606 is installed at the lower end of the one-way screw 603. The bevel gear 605 and the bevel gear 606 mesh and transmit power.

[0028] In this embodiment, a bidirectional screw 607 is provided below the drive rod 604. A servo motor is provided at the power end of the bidirectional screw 607. The bidirectional screw 607 is rotatably mounted on the mounting plate 1. The bidirectional screw 607 is threadedly connected to the slide plate 601. The servo motor drives the bidirectional screw 607 to rotate, and the bidirectional screw 607 drives the two slide plates 601 to move on the mounting plate 1, thereby adjusting the position of the two mounting plates 1.

[0029] In this embodiment, the fixing plate 3 and the lifting plate 602 are connected by fixing bolts. By removing the fixing bolts, the fixing plate 3 and the air pipe 4 can be replaced. One end of the air pipe 4 is set in a "T" shape.

[0030] The implementation principle is as follows: During operation, the servo motor controls the rotation of the bidirectional threaded rod 201, which drives the two sliders 202 to move closer to each other. The sliders 202 drive the arc plate 203 to move accordingly, thereby clamping and fixing the motor housing on which the stator is installed. Then, the servo motor drives the bidirectional screw 607, which drives the two slide plates 601 to move to the preset position and then stops. The servo motor then controls the drive rod 604 to work, which drives the unidirectional screw 603 to rotate. The unidirectional screw 603 drives the lifting plate 602 to slide on the slide plate 601. At the same time, the lifting plate 602 drives the fixing plate 3 and the air pipe 4 to move downward. The air pipe 4 drives the air bag 5 into the inside of the rotor and stops after reaching the preset position. Then, the air bag 5 is inflated through the air pipe 4, thereby expanding the air bag 5. The rotor can then be directly installed into the inside of the stator. After completion, the air bag 5 can be retracted and removed by reversing the control.

Various modifications and variations can be made to this utility model by those skilled in the art.
