Description

Technical Field

[0001] This utility model relates to the field of motor assembly technology, and in particular to a motor assembly fixture. Background Technology

[0002] Stator and rotor assembly is a very common process in the motor industry. The rotor is placed inside the stator and pressed into place, requiring it to be centered and kept in this centered position throughout the assembly process. Some assemblers directly assemble the stator and rotor by hand. During assembly, misalignment due to rotor lateral attraction can damage bearings and magnets. During pressing, magnetic forces can also cause eccentricity, making proper pressing difficult. This method of assembly can lead to the rotor adhering to one side of the stator's inner wall, resulting in assembly difficulties, bearing damage, low production efficiency, and a high defect rate. Utility Model Content

[0004] To achieve the above objectives, this utility model proposes a motor assembly fixture for installing a rotor into a stator, the motor assembly fixture comprising:

[0005] The support mechanism includes a fixed base, which has a limiting member and a mounting cavity for placing the stator. The limiting member is rotatably connected to the fixed base and is used to fix the stator.

[0006] A first clamping mechanism includes a first push rod and a first drive assembly. The first drive assembly is disposed on the support mechanism and is connected to the first push rod, driving the first push rod to slide along the support mechanism.

[0007] The second clamping mechanism includes a second push rod and a second drive assembly. One end of the second push rod is provided with a positioning groove for placing the rotor shaft. The second drive assembly is disposed on the support mechanism and is connected to the second push rod, driving the second push rod to slide along the support mechanism, so that the second push rod has a receiving position and an assembly position. In the receiving position, the second push rod is located in the cavity of the stator. The first drive assembly drives the first push rod to move toward the rotor and cooperates with the second push rod to clamp the rotor, so that the axis of the rotor is in the same straight line as the axis of the stator. The second drive assembly drives the second push rod to descend so that the rotor enters the stator.

[0008] In one embodiment, the second clamping mechanism further includes a push rod and a second connecting rod. The end of the second push rod opposite to the positioning groove is fixedly connected to the push rod, and the end of the push rod opposite to the second push rod is connected to the second connecting rod. The second connecting rod is connected to the second driving assembly, and the second connecting rod is also slidably connected to the support mechanism.

[0009] In one embodiment, the second drive assembly includes a second power component, a lead screw, and a connecting block. The lead screw is rotatably connected to the support mechanism, the connecting block is threadedly connected to the lead screw, and the connecting block is fixedly disposed on the second connecting rod. The second power component is connected to the lead screw and drives the lead screw to rotate, thereby causing the second connecting rod to slide along the support mechanism.

[0010] In one embodiment, the support mechanism is provided with a sensor, the second connecting rod is provided with a trigger, and the trigger frame cooperates with the sensor to trigger.

[0011] In one embodiment, the support mechanism is provided with a guide seat, the guide seat is provided with a guide channel, and the push rod is slidably disposed in the guide channel.

[0012] In one embodiment, the first clamping mechanism further includes a first connecting rod, which is slidably connected to the support mechanism. The first top rod is fixedly disposed on the first connecting rod, and the first driving component is connected to the first connecting rod and drives the first connecting rod to slide along the support mechanism.

[0013] In one embodiment, the first push rod includes a connecting portion and a tip portion, the connecting portion being fixedly connected to the first connecting rod, and the tip portion being used to abut against the rotor shaft.

[0014] In one embodiment, the support mechanism includes a support platform and a first fixed frame and a second fixed frame connected to the support platform. The fixed seat is disposed on the support platform, and the first fixed frame and the second fixed frame are respectively disposed on opposite sides of the support platform. The first driving component is connected to the first fixed frame, and the second driving component is connected to the second fixed frame.

[0015] In one embodiment, the first fixing frame includes a first fixing plate and at least two first guide rods arranged in parallel, one end of the first guide rods being connected to the first fixing plate and the other end being connected to the support platform.

[0016] In one embodiment, the second fixing frame includes a second fixing plate and at least two parallel support rods. One end of each support rod is connected to the second fixing plate, and the other end is connected to a support platform. A second guide rod is also connected between the support platform and the second fixing plate, and the second guide rod is connected to the second drive assembly.

[0017] This utility model's technical solution employs a fixed base on a support mechanism, with an installation cavity on the fixed base. The stator is placed within the installation cavity, and a rotation limiting component, in conjunction with the fixed base, clamps and secures the stator. A first clamping mechanism and a second clamping mechanism cooperate to clamp the rotor, ensuring that the rotor's axis is aligned with the stator's axis. The rotor's shaft is placed in a positioning groove. A first drive assembly drives a first push rod to descend and abut against the rotor's shaft, cooperating with a second push rod to clamp the rotor. A second drive assembly then drives a second push rod to descend, thereby installing the rotor into the stator. In this way, during the assembly process, the rotor is clamped, its axis aligning with the stator's axis. This prevents collisions and damage between the rotor and stator during the second drive assembly's movement into the stator, resulting in high efficiency and improved product yield.

[0034] In existing technologies, motor assembly involves directly hand-assembling the stator and rotor. During assembly, misalignment due to rotor lateral attraction can damage bearings and magnets. Furthermore, during press-fitting, magnetic forces can cause eccentricity, making proper press-fitting difficult. This method also leads to the rotor adhering to one side of the stator's inner wall, resulting in assembly difficulties, bearing damage, low production efficiency, and a high defect rate.

[0035] This utility model proposes a motor assembly fixture.

[0036] Please see Figures 1 to 5As shown, in one embodiment of the present invention, the motor assembly fixture is used to install the rotor 10 into the stator 20. The motor assembly fixture includes: a support mechanism 100, a first clamping mechanism 200, and a second clamping mechanism 300. The support mechanism 100 is provided with a fixed seat 110. The fixed seat 110 is provided with a limiting member 120 and an installation cavity 111 for placing the stator 20. The limiting member 120 is rotatably connected to the fixed seat 110 and is used to fix the stator 20. The first clamping mechanism 200 includes a first push rod 210 and a first drive assembly 220. The first drive assembly 220 is disposed on the support mechanism 100 and is connected to the first push rod 210, driving the first push rod 210 to slide along the support mechanism 100. The second clamping mechanism 300 includes a second push rod 310 and a second drive assembly 320. One end of the second push rod 310 is provided with a positioning groove 311 for placing the rotor 10 shaft. The second drive assembly 320 is disposed on the support mechanism 100 and is connected to the second push rod 210. The first drive assembly 220 connects and drives the second push rod 310 to slide along the support mechanism 100, so that the second push rod 310 has a receiving position and an assembly position. In the receiving position, the second push rod 310 is located in the cavity of the stator 20, and the rotating shaft of the rotor 10 is located in the positioning groove 311. The first drive assembly 220 drives the first push rod 210 to move toward the rotor 10 and cooperates with the second push rod 310 to clamp the rotor 10, so that the axis of the rotor 10 is in the same straight line as the axis of the stator 20. The second drive assembly 320 drives the second push rod 310 to descend so that the rotor 10 enters the stator 20.

[0037] In this embodiment, the support mechanism 100 provides support, and the fixing seat 110 is fixed on the support mechanism 100. The top surface of the fixing seat 110 is recessed to form a mounting cavity 111. The fixing seat 110 is also connected to a limiting member 120, which can be a limiting plate or a limiting rod, etc. In specific implementation, the limiting member 120 is a limiting plate structure. The limiting plate has an opening and a notch communicating with the opening, and the side wall of the opening forms an abutment portion. The stator 20 enters the opening through the notch and further enters the mounting cavity 111. The limiting plate rotates, causing the abutment portion to abut against the outer periphery of the stator 20. The limiting plate is then locked to the fixing seat 110 by bolts, thereby limiting the position of the stator 20. It should be noted that the limiting member has an elongated hole, which is arc-shaped. The bolt passes through the elongated hole and locks the connecting fixing seat 110. The abutting part of the limiting member 120 protrudes towards the center. When the limiting member 120 rotates, the abutting part approaches the connection point with the outer wall of the stator 20 and abuts against the outer wall of the servo motor stator, thereby achieving the fixing function. Of course, it is also applicable to most flange motors.

[0038] Understandably, the bottom surface of the base also has a clearance hole communicating with the mounting cavity 111, so that the second push rod 310 can extend into the mounting cavity 111 through the clearance hole to receive the rotor 10. Understandably, the first clamping mechanism 200 is located above the fixed base 110, and the second clamping mechanism 300 is located below the mounting base. When the stator 20 is placed in the mounting cavity 111, the second push rod 310 is in the receiving position, and the top end of the second push rod 310 is located in the cavity of the stator 20 for mounting the rotor 10. One end of the rotor 10's shaft is inserted into the positioning groove 311 of the second push rod 310, and the magnetic part of the rotor 10 is higher than the stator 20, that is, located outside the stator 20. The first drive assembly 220 drives the first push rod 210 to descend and abut against the end of the rotor 10's shaft away from the second push rod 310, thereby cooperating with the second push rod 310 to clamp the rotor 10. In the specific implementation process, the axes of the first push rod 210 and the second push rod 310 are coaxial with the axis of the stator 20, clamping the rotor 10 and making the axis of the rotor 10 coaxial with the first push rod 210 and the second push rod 310, thereby making the rotor 10 coaxial with the stator 20 to ensure accurate positioning of the rotor 10. The second drive assembly 320 drives the second push rod 310 to descend, while the first drive assembly 220 drives the first push rod 210 to descend, so that the first push rod 210 and the second push rod 310 always clamp the rotor 10, thereby assembling the rotor 10 into the stator 20.

[0039] In this embodiment, the first drive assembly 220 and the second drive assembly 320 can be structures such as cylinders or motors, which drive the first push rod 210 and the second push rod 310 to rise and fall. This embodiment is not limited to any particular structure. The bracket structure plays a supporting and guiding role. Specifically, both the first push rod 210 and the second push rod 310 slide and rise along the bracket, which is beneficial for their positioning and the positioning of the rotor 10.

[0040] This utility model's technical solution employs a fixed seat 110 on a support mechanism 100, with an installation cavity 111 on the fixed seat 110. The stator 20 is placed within the installation cavity 111, and a rotation limiting member 120, in conjunction with the fixed seat 110, clamps and fixes the stator 20. A first clamping mechanism 200 and a second clamping mechanism 300 cooperate to clamp the rotor 10, ensuring that the axis of the rotor 10 and the axis of the stator 20 are aligned. The rotor 10's shaft is placed within the positioning groove 311. A first driving assembly 220 drives a first push rod 210 to descend and abut against the rotor 10's shaft, cooperating with a second push rod 310 to clamp the rotor 10. The second driving assembly 320 then drives the second push rod 310 to descend, thereby installing the rotor 10 within the stator 20. In this way, during the assembly of the rotor 10 into the stator 20, the rotor 10 is clamped and its axis coincides with the axis of the stator 20. During the process of driving the rotor 10 into the stator 20 by the second drive assembly 320, the rotor 10 is avoided from colliding with the stator 20 and being damaged. This also improves efficiency and increases product yield.

[0041] In one embodiment, the second clamping mechanism 300 further includes a push rod 330 and a second connecting rod 340. One end of the second push rod 310 away from the positioning groove 311 is fixedly connected to the push rod 330, and the other end of the push rod 330 away from the second push rod 310 is connected to the second connecting rod 340. The second connecting rod 340 is connected to the second driving assembly 320, and the second connecting rod 340 is also slidably connected to the support mechanism 100.

[0042] In practical implementation, the second connecting rod 340 is equipped with a linear bearing, which allows it to slide along the support mechanism 100. The second connecting rod 340 is bolted to the bottom of the support rod. A connecting groove is provided at the top of the push rod 330, and the bottom of the second top rod 310 is inserted into the connecting groove and interference-fitted with it. The second drive assembly 320 drives the second connecting rod 340 to rise and fall, and the push rod 330 drives the second top rod 310 to rise and fall.

[0043] Furthermore, the second drive assembly 320 includes a second power component 321, a lead screw 322, and a connecting block 323. The lead screw 322 is rotatably connected to the support mechanism 100, and the connecting block 323 is threadedly connected to the lead screw 322. The connecting block 323 is fixedly mounted on the second connecting rod 340. The second power component 321 is connected to the lead screw 322 and drives the lead screw 322 to rotate, thereby causing the second connecting rod 340 to slide along the support mechanism 100.

[0044] In specific implementation, the second power component 321 can be a motor or a cylinder, etc. This embodiment describes the second power component 321 as a motor. The second power component 321 is fixed on the bracket and drives the connecting screw 322 via a belt or gear set, causing the screw 322 to rotate. Specifically, the screw 322 is vertically arranged, with both ends rotatably connected to the bracket mechanism 100. The first power component is connected to the screw 322 near its top. The rotation of the screw 322 causes the connecting block 323 to slide up and down along the screw 322. The second connecting rod 340 is fixedly connected to the connecting block 323, thereby causing the second connecting rod 340 to rise and fall along the screw 322. In specific implementation, one end of the second connecting rod 340 is connected to a linear bearing and slidably connected to the bracket mechanism 100, while the other end is connected to the connecting block 323 and rotatably connected to the screw 322. The screw 322 also ensures the stability of the second connecting rod 340 during descent, thus achieving stable rising and falling of the second connecting rod 340.

[0045] In one embodiment, the support mechanism 100 is provided with a sensor 400, and the second link 340 is provided with a trigger 410, which cooperates with the sensor 400 to trigger.

[0046] In the specific implementation process, three sensors 400 are provided and spaced apart along the vertical direction of the support mechanism 100. When in the receiving position, the trigger 410 is triggered by the uppermost sensor 400, causing the second drive assembly 320 to stop, indicating that the receiving position has been reached. Then, the rotor 10 is placed on the second push rod 310 and prepared for descent and assembly. When the second push rod 310 descends to trigger the middle sensor 400, it indicates that the rotor 10 is assembled in place, and the second drive assembly 320 stops driving. The lowermost trigger 410 indicates that the second push rod 310 has reached its limit position. At this point, an error may occur, and an alarm signal, such as a buzzer, will be issued.

[0047] In one embodiment, the support mechanism 100 is provided with a guide seat 130, the guide seat 130 is provided with a guide channel 131, and the push rod 330 is slidably disposed in the guide channel 131.

[0048] In the specific implementation process, the guide seat 130 is located below the fixed seat 110. In order to improve the sliding accuracy and stability of the push rod 330, a guide channel 131 is opened in the guide seat 130, and the push rod 330 slides and rises and falls along the guide channel 131. It can be understood that the guide channel 131 is connected to the mounting groove.

[0049] In one embodiment, the first clamping mechanism further includes a first link 230, which is slidably connected to the support mechanism 100. A first push rod 210 is fixedly disposed on the first link 230, and a first driving assembly 220 is connected to the first link 230 and drives the first link 230 to slide along the support mechanism 100.

[0050] Specifically, linear bearings are provided at both ends of the first connecting rod 230, and they slide along the support mechanism 100 to improve the stability of the first connecting rod 230. The first push rod 210 is connected to the bottom surface of the first connecting rod 230, and the first drive assembly 220 is a cylinder structure or a motor structure, etc., and is fixed on the support mechanism 100. When the first drive assembly 220 is a cylinder, the extension rod of the cylinder is connected to the first connecting rod 230, and drives the first push rod 210 to rise and fall through the first connecting rod 230. During the process of installing the rotor 10 into the stator 20, that is, during the process of the second drive assembly 320 driving the rotor 10 to descend, the extension rod of the cylinder always abuts against the rotating shaft of the rotor 10. It can be understood that, in one embodiment, the cylinder is connected to the air circuit system, and the air circuit system is equipped with a safety valve to ensure that the extension rod always abuts against the rotor and protects the safety of the entire air circuit. In another embodiment, the cylinder is connected to the control system. When the cylinder abuts against the rotating shaft of the rotor 10, the control system controls the extension stroke of the cylinder extension rod to be consistent with the stroke of the second drive assembly 320 driving the second push rod 310 to descend, so as to ensure that the first push rod 210 and the second push rod 310 always clamp the rotating shaft of the rotor 10.

[0051] Furthermore, the first push rod 210 includes a connecting portion and a tip portion. The connecting portion is fixedly connected to the first connecting rod 230, and the tip portion is used to abut against the rotating shaft of the rotor 10. The tip portion abuts against the end face of the rotating shaft of the rotor 10 to cooperate with the second push rod 310 to clamp the rotor 10, and the connecting portion is fixedly connected to the first connecting rod 230.

[0052] In one embodiment, the support mechanism 100 includes a support platform 140 and a first fixed frame 150 and a second fixed frame 160 connected to the support platform 140. A fixed seat 110 is disposed on the support platform 140. The first fixed frame 150 and the second fixed frame 160 are respectively disposed on opposite sides of the support platform 140. A first drive assembly 220 is connected to the first fixed frame 150, and a second drive assembly 320 is connected to the second fixed frame 160.

[0053] It should be noted that the support mechanism 100 includes multiple rod-like structures and plate-like structures, which serve as supports and guides to ensure assembly accuracy. In this embodiment, the first fixing frame 150 is fixedly connected to the top of the support platform 140 by bolts, and the second fixing frame 160 is fixedly connected to the bottom of the support platform 140 by bolts, and is respectively connected to the first drive assembly 220 and the second drive assembly 320.

[0054] In the specific implementation process, the first fixing frame 150 includes a first fixing plate 151 and at least two first guide rods 152 arranged in parallel. One end of the first guide rod 152 is connected to the first fixing plate 151, and the other end is connected to the support platform 140.

[0055] Two first guide rods 152 are arranged in parallel, with the bottom end connected to the support platform 140 and the top end connected to the first fixed plate 151. The first drive assembly 220 is fixed on the first fixed plate 151 and connected to the first connecting rod 230 to drive the first connecting rod 230 to slide along the first guide rod 152, thereby driving the first top rod 210 to rise and fall.

[0056] Accordingly, the second fixing frame 160 includes a second fixing plate 161 and at least two support rods 162. One end of the support rod 162 is connected to the second fixing plate 161 and the other end is connected to the support platform 140. A second guide rod 163 is also connected between the support platform 140 and the second fixing plate 161. The second guide rod 163 is connected to the second drive assembly 320.

[0057] Two support rods 162 are arranged in parallel, with one end connected to the bottom of the support platform 140 and the other end connected to the second fixing plate 161, serving as a fixed support. The two ends of the lead screw 322 of the second drive assembly 320 are connected to the support platform 140 and the second fixing plate 161, respectively. The second guide rod 163 is parallel to the lead screw 322, and the second connecting rod 340 connects the second guide rod 163 and the lead screw 322, improving the stability of the lifting and lowering of the second connecting rod 340.
