Description

Technical Field

[0001] This utility model relates to the field of motor manufacturing and transportation technology, and in particular to a motor rotor transportation device. Background Technology

[0002] As the core moving component of a motor, the rotor has a precise and complex structure, typically including journals, core, windings, and key components such as commutators or slip rings. These components face multiple risks during transportation: journals, being precision mating surfaces, can easily lead to dimensional deviations even from slight impacts; laminated cores are prone to deformation under external forces, affecting the uniformity of the motor's air gap; winding insulation is fragile, and compression and friction can cause insulation damage; scratches on the working surfaces of the commutator / slip rings directly affect motor performance. Existing transportation methods have significant drawbacks: simple stacking leaves rotors in a disordered state, making them susceptible to collisions during transport, especially at the contact points between journals and cores; while simple supports can achieve basic positioning, they lack adjustability, cannot adapt to the support requirements of rotors of different specifications, and have limited shock absorption; general-purpose tooling, not specifically designed for rotors, often suffers from unreasonable support point distribution and insufficient protection of critical parts, making it difficult to effectively prevent rotor damage during long-distance transportation or intra-factory handling. Summary of the Invention

[0003] In view of this, the purpose of this utility model is to provide a motor rotor transport device that can realize an adjustable support structure, effectively protect the key parts of the rotor, and prevent collision damage during transportation.

[0005] Furthermore, an anti-detachment block is provided at the end of the first screw.

[0006] Furthermore, a second screw corresponding to the threaded hole is provided on the lower surface of the support limiting rod.

[0007] Furthermore, the lower surface of the limiting plate is provided with an anti-slip layer, and the lifting block is provided with a second motor for driving the limiting plate to rotate up and down.

[0012] The present invention will be further described below with reference to the accompanying drawings.

[0013] Please see Figures 1 to 3 As shown, this utility model provides an embodiment: a motor rotor transport device, including a transport box 1 with an open upper surface, threaded holes 2 are evenly spaced on the bottom surface of the transport box 1, a support limiting rod 3 is spirally embedded in the threaded holes 2, and strip-shaped grooves 4 are provided at both the front and rear ends of the support limiting rod 3. A first motor (not shown) is embedded in the bottom surface of the strip-shaped groove 4, and a first screw 6 is connected to the output end of the first motor. A lifting block 61 is spirally sleeved on the first screw 6, and a limiting plate 62 is hinged to the lifting block 61 via a rotating shaft.

[0014] The transport box 1 is a container for housing the rotor, which can be a composite structure of a metal frame and a shock-absorbing liner. Its open design facilitates loading and unloading. The threaded holes 2 are connection interfaces evenly distributed along the bottom of the box, which can be M12 standard threads, used to fix the position of the support limit rod. The support limit rod 3 is a vertically installed column assembly inside the box, which can be made of stainless steel and allows for adjustment of the insertion depth by rotation to accommodate different rotor lengths. The strip groove 4 is a guide structure extending axially along the support rod, which can be a U-shaped groove design to provide a running track for the lifting mechanism. The first motor is the power source driving the lifting assembly, which can be a stepper motor, achieving precise lifting by controlling the rotation angle. The first screw 6 is a transmission component linked to the motor, which can be a trapezoidal threaded rod, converting rotational motion into linear displacement. The lifting block 61 is a load-bearing component that moves along the screw, which can be an aluminum alloy slider with a lubricating coating on its surface to reduce frictional resistance. The limiting plate 62 refers to the contact component that clamps the rotor. Specifically, it can be an arc-shaped plate covered with polyurethane, and the angle can be adjusted through a hinge structure.

[0015] Specifically, the array of threaded holes at the bottom of the transport container allows the support limiting rods to be installed in different positions as needed. When handling rotors of different lengths, the spacing between adjacent rods is adjusted by rotating the support limiting rods to match the spacing at the rotor shaft ends. Within the strip-shaped grooves at both ends of the support limiting rods, a first motor drives a first screw to rotate, causing a lifting block to move vertically along the groove. After the lifting block reaches the set height, the hinged limiting plate can rotate around the axis to an angle that fits against the rotor surface, forming a three-point contact fixation. During this process, the arc-shaped contact surface of the limiting plate disperses pressure, avoiding localized stress concentration on the rotor journal.

[0016] Compared to existing technologies, traditional fixing methods rely on fixed-spacing support structures, which cannot adapt to variations in rotor dimensions. This solution, however, achieves dual adjustment of support height and horizontal spacing through a combination of adjustable support limit rods and lifting blocks. Existing temporary support materials lack rigid connections and are prone to displacement under transport vibrations. In this solution, the screw drive and threaded locking structure provide stable mechanical support. Furthermore, the rigid limiting components of traditional tooling are prone to scratching the rotor surface. This solution employs a hinged limiting plate and a flexible contact layer, ensuring effective fixing while reducing the risk of surface damage.

[0017] Through the above technical solution, this application can flexibly adjust the support point position and clamping height according to the rotor size, ensuring that the rotor and the limiting components maintain stable contact during transportation. The lifting mechanism in the strip groove achieves precise positioning in the vertical direction, while the adaptive angle adjustment function of the hinged limiting plate effectively disperses vibration and impact forces. This device solves the problem of mutual collision caused by insecure fixing in traditional transportation methods, while avoiding damage to the precision parts of the rotor caused by rigid contact.

[0018] Please continue reading. Figures 1 to 3 As shown, in one embodiment of the present invention, an anti-detachment block 63 is provided at the end of the first screw 6.

[0019] The anti-slip block 63 is a blocking component fixed to the end of the screw to limit the displacement range of the lifting block. It can be implemented by welding a metal block or by threaded connection, and its diameter is larger than the outer diameter of the screw to prevent the lifting block from slipping off the end. This component prevents the lifting block from detaching from the screw track during movement through physical blocking, ensuring the stability of the lifting adjustment process.

[0020] Specifically, when the first motor drives the first screw to rotate, the lifting block moves along the screw axis to adjust the height of the limiting plate. When the lifting block moves to the extreme position at the end of the screw, the anti-detachment block contacts the lifting block to form a mechanical limit, preventing the lifting block from sliding outwards further. This structure ensures that the lifting block always remains within the effective stroke range of the screw, preventing equipment failure due to accidental overtravel.

[0021] Compared to existing technologies, conventional screw drive devices lack a limiting structure at the end, making it easy for the lifting block to detach from the screw due to inertia or misoperation, leading to sudden displacement of the limiting plate and rotor collision. This solution eliminates the risk of the lifting block derailing by using a rigid blocking block at the end.

[0022] Through the above technical solution, this application effectively solves the problem of displacement of the limiting plate caused by the instability of the screw drive mechanism during transportation, making the vertical fixation of the rotor in the transport box more reliable and avoiding axial movement damage to the rotor caused by accidental detachment of the limiting plate.

[0023] Please continue reading. Figures 1 to 3 As shown, in one embodiment of the present invention, a second screw 31 corresponding to the threaded hole 2 is provided on the lower surface of the support limiting rod 3.

[0024] The support limiting rod 3 is a rod-shaped component used to vertically fix the motor rotor. It can be made of metal and machined into a cylindrical structure. The threaded hole on its surface is used to match the installation requirements of the second screw. The second screw 31 is a threaded rod connected to the bottom of the support limiting rod. It can be machined to form an external thread structure, and its function is to adjust the vertical height of the support limiting rod by screwing it into the threaded hole. The threaded hole is a hole with internal threads opened on the bottom surface of the transport box. It can be machined using a drilling and tapping process to form a threaded fit with the second screw, thereby fixing the position of the support limiting rod.

[0025] Specifically, the second screw at the bottom of the support limiting rod forms a detachable threaded connection with the threaded hole at the bottom of the transport box. When it is necessary to adjust the installation height of the support limiting rod, the second screw can be screwed into or out of the threaded hole by rotating the support limiting rod, thereby changing the contact depth between the bottom end of the support limiting rod and the bottom surface of the transport box. After adjustment, the thread engagement between the second screw and the threaded hole prevents axial displacement of the support limiting rod during transportation.

[0026] Compared to existing technologies, the simple supports currently used in existing systems rely solely on friction for fixation using wooden blocks or foam, making them prone to slippage during transport vibrations. This solution, however, utilizes a rigid connection structure formed by threaded engagement to completely eliminate the risk of axial displacement of the support rod. Furthermore, general-purpose tooling lacks height adjustment capabilities, requiring frequent replacement of adapter parts. This solution, through continuous adjustment of the thread depth, can adapt to the support requirements of rotors of different specifications.

[0027] Through the above technical solution, this application realizes the rapid installation and precise height adjustment of the support limit rod, solves the problem of rotor shaking caused by the insecure fixing of the support rod in the prior art, and avoids the safety hazards caused by the loosening of the support rod during transportation through the thread self-locking characteristic.

[0028] Please continue reading. Figures 1 to 3 As shown, in one embodiment of the present invention, the lower surface of the limiting plate 62 is provided with an anti-slip layer 64, and the lifting block 61 is provided with a second motor (not shown) for driving the limiting plate 62 to rotate up and down.

[0029] The anti-slip layer 64 refers to the friction-enhancing structure attached to the contact surface of the limiting plate. It can be made of rubber or silicone, and its surface can be designed with a textured surface to increase contact resistance, preventing the rotor from shifting due to inertia during transport. The second motor is the drive device whose output shaft connects to the limiting plate's rotating shaft. It can be implemented using a servo motor or stepper motor, converting rotational motion into adjustment of the limiting plate's flipping angle via gear transmission or a linkage mechanism. This allows for proactive adjustment of the limiting plate's clamping posture based on the rotor's shape.

[0030] Specifically, the anti-slip layer increases the friction of the contact surface, creating a stable constraint when the limiting plate contacts the rotor journal or iron core, thus preventing relative displacement caused by transportation vibrations. The second motor precisely controls the flipping angle of the limiting plate, allowing it to adapt to rotors of different diameters or lengths. Based on the height adjustment of the lifting block, the clamping position is further optimized to ensure that the rotor axis remains perpendicular to the supporting limiting rod.

[0031] Compared to existing technologies, current simple supports rely on manual adjustment of the position of wooden blocks or foam, which cannot dynamically adapt to rotors of different specifications and lack anti-slip measures, leading to fixation failure. This solution achieves automated adjustment of the clamping angle and anti-slip function of the contact surface through motor-driven limit plate flipping and the setting of anti-slip layer, solving the problems of inaccurate protection and poor stability of traditional tooling.

[0032] Through the above technical solution, this application can effectively prevent journal damage caused by sliding or clamping angle deviation during the transportation of the rotor. At the same time, by dynamically adjusting the angle of the limiting plate, it can accurately adapt to rotors of different sizes, avoiding core deformation and winding damage under pressure.

[0033] The motor used in this invention is existing technology, which is already well understood by those skilled in the art, and will not be described in detail here.

[0034] The above description is only a preferred embodiment of the present utility model. All equivalent changes and modifications made within the scope of the patent application of the present utility model shall be covered by the present utility model.
