Description

Technical Field

[0001] This utility model relates to the field of permanent magnet motor assembly, specifically to a permanent magnet motor assembly fixture. Background Technology

[0002] A permanent magnet synchronous motor is a synchronous motor that uses permanent magnets to generate a magnetic field. It consists of a rotor and a stator.

[0003] During the assembly of a permanent magnet motor, the rotor needs to be guided axially into the stator. However, the stator of a permanent magnet motor contains magnets, which exert a strong attraction on other iron parts and tools. Under the influence of the magnetic force, the rotor can easily collide with the stator uncontrollably, causing damage to the stator or rotor.

[0004] Therefore, how to prevent the rotor from uncontrollably impacting the magnets inside the stator during assembly is a technical problem that urgently needs to be solved. Utility Model Content

[0005] The purpose of this invention is to overcome the above-mentioned technical deficiencies and propose a permanent magnet motor assembly fixture to solve the technical problem in the prior art of avoiding uncontrolled impact of the rotor on the magnets inside the stator during the assembly process.

[0006] To achieve the above-mentioned technical objectives, the present invention adopts the following technical solution: This utility model provides a permanent magnet motor assembly fixture, which includes: The rack has a first area and a second area; and A clamping assembly includes a clamping member and a driving member. The clamping member has a first state of clamping a rotor axially and a second state of disengaging from the rotor axially. The clamping member is slidably disposed between a first region and a second region. The driving member is throttle connected to the clamping member and drives the clamping member to move between the first region and the second region.

[0007] In some embodiments, the clamping member includes a first clamping portion, a second clamping portion, and an elastic portion. The first clamping portion and the second clamping portion are both slidably disposed on the frame. The elastic portion is connected to the first clamping portion and the frame at both ends, and has a spring force that pushes the first clamping portion closer to the second clamping portion so that the first clamping portion and the second clamping portion clamp the rotor. By overcoming the spring force of the elastic portion, the clamping member is switched from a first state to a second state. The driving member is driven to the second clamping portion, and drives the second clamping portion to move relative to the frame.

[0008] In some embodiments, the first clamping portion includes a first pressure rod that is slidably disposed on the frame along the axial direction, and the second clamping portion includes a second pressure rod that is disposed opposite to the first pressure rod and is slidably disposed on the frame along the axial direction.

[0009] In some embodiments, the elastic portion includes a spring sleeved around the outer periphery of the first pressure rod, one end of the spring being connected to the first pressure rod and the other end being connected to the frame, the spring having an elastic force that pushes the first pressure rod closer to the second pressure rod.

[0010] In some embodiments, the frame has a first guide hole and a second guide hole, the first pressure rod is movably inserted through the first guide hole, and the second pressure rod is movably inserted through the second guide hole.

[0011] In some embodiments, the frame has a screw hole, the drive component includes a screw and a handle, the screw is screwed into the screw hole, and one end of the screw is rotatably connected to the second pressure rod, and the handle is mounted on the other end of the screw.

[0012] In some embodiments, the permanent magnet motor assembly fixture further includes a positioning seat, which is installed in the first region and is detachably connected to the stator.

[0015] In some embodiments, the clamping member is an aluminum alloy clamping member.

[0016] Compared with the prior art, the permanent magnet motor assembly fixture provided by this utility model has the following advantages: First, the stator is fixed in the first region. Then, the clamping member is moved to the second region and switched to the first state, thus clamping the rotor. The driving component then moves the clamping member back to the first region, embedding the rotor into the stator. The clamping member is then switched to the second state, detaching from the rotor. Using this permanent magnet motor assembly fixture, the rotor can be gradually guided into the stator, preventing uncontrolled impacts between the rotor and the stator magnets during assembly and avoiding damage from impacts.

Detailed Implementation

[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0019] To address the technical problem of preventing the rotor from uncontrollably impacting the magnets inside the stator during assembly, this invention provides a permanent magnet motor assembly fixture that can gradually guide the rotor into the stator, thus preventing the rotor from uncontrollably impacting the magnets inside the stator.

[0020] It should be noted that the permanent magnet motor assembly fixture of this utility model is used for, but not limited to, permanent magnet motor assembly. For ease of explanation, this utility model will only use the application of the permanent magnet motor assembly fixture to permanent magnet motor assembly as an example for explanation.

[0021] Please see Figure 1 , Figure 1 This is a schematic diagram of the structure of a permanent magnet motor assembly fixture in one embodiment of the present invention. The permanent magnet motor assembly fixture includes a frame 100 and a clamping assembly 200. The frame 100 has a first region and a second region. The clamping assembly 200 includes a clamping member 210 and a driving member 220. The clamping member 210 has a first state of clamping the rotor along the axial direction and a second state of disengaging from the rotor along the axial direction. The clamping member 210 is slidably disposed between the first region and the second region. The driving member 220 is connected to the clamping member 210 in a transmission manner, and drives the clamping member 210 to move between the first region and the second region.

[0022] In this embodiment, the stator is first fixed in the first region. Then, the clamping member 210 is moved to the second region and switched to the first state, thereby clamping the rotor. The driving member 220 then moves the clamping member 210 towards the first region, allowing the rotor to embed into the stator. Subsequently, the clamping member 210 is switched to the second state, disengaging from the rotor. Using the aforementioned permanent magnet motor assembly fixture, the rotor can be gradually guided into the stator. During the rotor guidance process, uncontrolled impacts of the rotor against the stator magnets can be avoided, preventing damage from impacts during permanent magnet motor assembly.

[0023] In some embodiments, the clamping member 210 includes a first clamping portion 211, a second clamping portion 212, and an elastic portion 213. Both the first clamping portion 211 and the second clamping portion 212 are slidably disposed on the frame 100. The elastic portion 213 is connected at both ends to the first clamping portion 211 and the frame 100, respectively, and has a spring force that pushes the first clamping portion 211 closer to the second clamping portion 212, so that the first clamping portion 211 and the second clamping portion 212 clamp the rotor. By overcoming the spring force of the elastic portion 213, the clamping member 210 switches from a first state to a second state. The driving member 220 is connected to the second clamping portion 212, driving the second clamping portion 212 to move relative to the frame 100. The first clamping portion 211 and the second clamping portion 212 respectively press against both ends of the rotor, thereby clamping the rotor using the first clamping portion 211 and the second clamping portion 212. When it is necessary to switch the clamping member 210 to the second state, the elastic part 213 can be compressed to overcome the elastic force of the elastic part 213, causing the first clamping part 211 to move away from the second clamping part 212. Then, the rotor can be placed between the first clamping part 211 and the second clamping part 212. Subsequently, the intervention on the elastic part 213 is stopped, and the elastic part 213 releases its elastic potential energy, which can push the first clamping part 211 closer to the second clamping part 212, causing the clamping member 210 to switch to the first state, so that the first clamping part 211 and the second clamping part 212 clamp the rotor.

[0024] In some embodiments, the first clamping part 211 includes a first pressure rod 2111, which is axially slidably disposed on the frame 100. The second clamping part 212 includes a second pressure rod 2121, which is opposite to the first pressure rod 2111 and axially slidably disposed on the frame 100. The first pressure rod 2111 and the second pressure rod 2121 are opposite to each other, such that the first pressure rod 2111 and the second pressure rod 2121 respectively press against both ends of the rotor central shaft, thereby clamping the rotor. Since the diameters of the first pressure rod 2111 and the second pressure rod 2121 are small, the first pressure rod 2111 and the second pressure rod 2121 can also extend into the stator, so that the rotor can be smoothly introduced into the stator.

[0025] Based on the above embodiments, in some embodiments, the elastic part 213 includes a spring 2131, which is sleeved on the outer periphery of the first pressure rod 2111. One end of the spring 2131 is connected to the first pressure rod 2111, and the other end is connected to the frame 100. The spring 2131 has a spring force that pushes the first pressure rod 2111 closer to the second pressure rod 2121. It is understood that in Figure 1 In the embodiment shown, elastic potential energy is stored by stretching the spring 2131. If the spring 2131 is installed in the opposite position, elastic potential energy can be stored by compressing the spring 2131.

[0026] In some embodiments, the frame 100 has a first guide hole 110 and a second guide hole 120. A first pressure rod 2111 is movably inserted through the first guide hole 110, and a second pressure rod 2121 is movably inserted through the second guide hole 120. Both the first guide hole 110 and the second guide hole 120 serve as limiting guides, allowing the first pressure rod 2111 to slide along the axial direction of the first guide hole 110, and the second pressure rod 2121 to slide along the axial direction of the second guide hole 120.

[0027] In some embodiments, the frame 100 has a screw hole 130, and the drive component 220 includes a screw 221 and a handle 222. The screw 221 is screwed into the screw hole 130, and one end of the screw 221 is rotatably connected to the second pressure rod 2121. The handle 222 is mounted on the other end of the screw 221. The operator can rotate the handle 222 to drive the screw 221 to rotate. Since the screw 221 and the screw hole 130 are screwed together, as the screw 221 rotates, the screw 221 will move along the axial direction of the screw 221, which can push the second pressure rod 2121 to slide relative to the second guide hole 120.

[0028] In some embodiments, the permanent magnet motor assembly fixture also includes a positioning seat 300, which is installed in the first region and is detachably connected to the stator. During the assembly of the permanent magnet motor, the stator needs to be connected to the positioning seat 300 to fix the stator on the frame 100 for subsequent assembly operations.

[0029] Based on the above embodiments, in some embodiments, the positioning seat 300 has a communication port 310, and the second pressure rod 2121 can pass through the communication port 310.

[0030] In some embodiments, the frame 100 is an aluminum alloy frame 100, and the clamping member 210 is an aluminum alloy clamping member 210. Since both the frame 100 and the clamping member 210 are made of aluminum alloy, which is a non-magnetic material, the frame 100 and the clamping member 210 are prevented from attracting each other to the permanent magnets of the stator.

[0031] To better understand this utility model, the following is combined with... Figure 1 The technical solution of this utility model is described in detail below: First, the stator is connected to the positioning seat 300, and then the stator is fixed to the frame 100, thus fixing the stator in the first region. The operator rotates the handle 222 to rotate the screw 221. Since the screw 221 and the screw hole 130 are screwed together, as the screw 221 rotates, it moves along its axial direction, thereby pushing the second pressure rod 2121 to slide relative to the second guide hole 120. This moves the clamping member 210 to the second region. Then, the first pressure rod 2111 and the second pressure rod 2121 press against the two ends of the rotor's central shaft, thereby clamping the rotor. Again, the screw 221 is rotated by the handle 222, which in turn moves the second pressure rod 2121, causing the clamping member 210 to move the rotor towards the first region, embedding the rotor into the stator. Using the aforementioned permanent magnet motor assembly fixture, the rotor can be gradually guided into the stator. During the process of guiding the rotor, uncontrolled impacts of the rotor into the stator magnets can be avoided, thus preventing damage from collisions during the assembly of the permanent magnet motor.
