[0001] The invention relates to the technical field of motor maintenance, in particular to a turning frame for motor maintenance. Background Art

[0002] In the field of electric motor repair and maintenance, tilting racks are widely used as auxiliary equipment during motor disassembly and overhaul. Existing technologies use clamps and rotating mechanisms to secure and tilt the motor. However, these tilting racks generally suffer from poor versatility.

[0003] While some tilting frames offer some adjustment features, such as manual adjustment of the clamp spacing, the process is cumbersome and time-consuming, requiring multiple adjustments using bolts, handwheels, and other tools. Manual adjustment of the tilting angle using a finger ring still requires manual assembly and disassembly of components to accommodate motors of varying lengths, making it difficult to quickly respond to maintenance needs. Summary of the Invention

[0004] Therefore, the technical problem to be solved by the present invention is that the turning frame has poor versatility, the clamp adjustment process is cumbersome and time-consuming, and it is difficult to quickly respond to maintenance needs.

[0005] The above technical problem is solved by the following technical solution: The present invention provides a turning frame for motor maintenance, which includes an adjusting element;

[0006] a receiving element, the receiving element being located between the two adjusting elements and being a bracket for placing the motor for maintenance; and

[0007] The clamping element is located at the top end of the adjusting element and is used to fix the motor to flip, wherein the clamping arm in the clamping element can move in the longitudinal direction.

[0008] In a preferred embodiment of the motor maintenance turning frame of the present invention, the adjusting element includes a base plate, and a screw rod is provided in the sliding groove of the base plate to drive the support frame to move in the lateral direction.

[0009] In a preferred embodiment of the motor maintenance turning frame of the present invention, the adjusting element further comprises a diagonal support plate arranged at the end of the base plate, and the front view of the diagonal support plate is triangular.

[0010] In a preferred embodiment of the motor maintenance turning frame of the present invention: a driving motor is installed on the top end of the supporting frame, and a connecting frame is installed on the output end of the driving motor.

[0011] In a preferred embodiment of the motor maintenance turning frame of the present invention: the side view of the support frame is an inverted "U" shape, and the top view of the connecting frame is a "U" shape, and the clamping elements are located at both ends of the connecting frame.

[0012] In a preferred embodiment of the motor maintenance turning frame of the present invention: the storage element includes a hydraulic rod arranged at the top of the base plate, and a bracket platform is installed at the piston rod end of the hydraulic rod, and the bracket platform is driven to move up and down by the hydraulic rod.

[0013] In a preferred embodiment of the motor maintenance turning frame of the present invention, the clamping arm includes a telescopic cylinder arranged on the outer wall of the connecting frame, and the piston rod of the telescopic cylinder passes through the connecting frame and is connected to the clamping block.

[0014] In a preferred embodiment of the turning frame for motor maintenance of the present invention, the clamping blocks are arranged in an "eight" shape, wherein a buffer airbag is provided in the middle position of the "eight" shape of the clamping blocks.

[0015] In a preferred embodiment of the motor maintenance turning frame of the present invention: the side walls of the clamping block are installed with tooth blocks, and the tooth blocks are located at both ends of the side walls of the clamping block, and the middle of the buffer airbag has a lower groove with the ends higher and the middle lower.

[0016] In a preferred embodiment of the motor maintenance turning frame of the present invention: an arc groove is provided between the two tooth blocks, wherein the height of the arc groove is lower than the tooth blocks at both ends, and the contact surface between the clamping block and the maintenance motor is made of rubber.

[0017] The beneficial effects of the present invention are that the position of the support frame is adjusted by the screw drive system, the distance of the clamping blocks is adjusted by the telescopic cylinder, and the clamping blocks are designed in an "eight" shape, so that the flip frame can adapt to motors of various sizes and shapes. This flexibility greatly enhances the versatility of the equipment, so that the same set of equipment can be used for maintenance work on motors of different models without the need to replace or significantly adjust the equipment. Traditional fixture adjustment usually requires manual adjustment of multiple components, which is a cumbersome and time-consuming process. In this embodiment, the electric adjustment function is realized through the built-in screw drive system and telescopic cylinder, and the position adjustment of the clamping arm can be quickly completed with simple operations. This not only simplifies the adjustment process, but also greatly shortens the preparation time and improves work efficiency.

[0018] Because the entire system is designed with convenience and efficiency in mind, everything from position adjustment to clamping and fixing can be completed quickly, enabling rapid response to various emergency maintenance needs. For example, in the event of an unexpected failure, maintenance personnel can immediately use the tilt rack to inspect and repair the motor without spending a lot of time on equipment debugging.

[0019] The use of cushioning airbags and rubber contact surfaces effectively prevents motor damage from over-clamping or improper operation. Furthermore, the "eight"-shaped clamping block and arc-shaped slot design further ensure the stability of the motor in the clamped state, reducing potential safety hazards during maintenance.

[0027] In order to enable those skilled in the art to better understand the present invention, the present invention is further described in detail below with reference to specific embodiments and the accompanying drawings.

[0028] The terms used in the present invention are those commonly used in the art in view of the functions of the present invention, but these terms may vary according to the intentions of those skilled in the art, precedents, or new technologies in the art. In addition, specific terms may be selected by the applicant, and in such cases, their detailed meanings will be described in the detailed description of the present invention. Therefore, the terms used in the specification should not be understood as simple names, but rather as the meanings of the terms and the overall description of the present invention.

[0029] Reference Figure 1 This embodiment provides a turning frame for motor maintenance, including an adjusting element 1, which is the basic supporting structure of the entire device, used to ensure overall stability and capable of adjusting the position and angle as needed to accommodate maintenance work on motors of different sizes and types;

[0030] The storage element 2 is located between the two adjustment elements 1. The storage element 2 is actually a specially designed bracket platform, which is used to place the motor to be repaired. The design of the bracket platform takes into account the convenience and safety of operation, ensuring that the motor can be firmly placed on it, while facilitating the operator to perform various maintenance operations. The storage element 2 is located between the two adjustment elements 1, and the storage element 2 is a bracket for placing the repaired motor; and the clamping element 3 is located at the top of the adjustment element 1 and is used to fix the motor to flip, wherein the clamping arm 31 in the clamping element 3 can move in the longitudinal direction, mainly used to fix the motor and support its flipping operation. The key part of the clamping element 3 is the clamping arm 31, which can move in the longitudinal direction to accommodate motors of different heights and sizes. The clamping arm 31 is equipped with components such as a telescopic cylinder 311, a clamping block 312 and a cushioning airbag 313. These components work together to ensure that the motor can be safely and firmly fixed during the maintenance process, while reducing the damage that the clamping process may cause to the motor.

[0031] When a motor needs to be repaired, the entire turning frame is first fixed in a stable position by the diagonal support plate 13. Then, the motor to be repaired is carefully placed in the center of the storage element 2 (i.e., the bracket platform 22) to ensure that the motor is in the best operating position.

[0032] Next, the screw system on the base plate 11 is activated, and the position of the clamping element 3 is adjusted through the adjustment element 1, so that it is precisely positioned at the ends of the motor. Subsequently, the telescopic cylinder 311 within the clamping element 3 is activated, driving the clamping arm 31 to move longitudinally to the predetermined position, and the clamping block 312 securely clamps the motor. During this process, the cushioning airbag 313 and the rubber material on the clamping block 312 act as a buffer, effectively absorbing the vibration generated during clamping and protecting the motor from damage.

[0033] After completing the above steps, you can start the maintenance work on the motor. If you need to turn the motor over to check its different sides or perform specific maintenance operations, the motor can be safely turned over through the coordinated operation between the adjustment element 1 and the clamping element 3, thus ensuring that the entire maintenance process is both efficient and safe.

[0034] Reference Figure 1-Figure 2 As an optional embodiment, the adjusting element 1 includes a base plate 11, and a screw rod is provided in the sliding groove of the base plate 11 to drive the support frame 12 to move in the horizontal direction.

[0035] The adjusting element 1 also includes a diagonal support plate 13 arranged at the end of the base plate 11. The front view of the diagonal support plate 13 is triangular. This design increases the stability of the entire device and ensures that no shaking or tilting occurs during operation. The diagonal support plate 13 is not connected to the support frame 12. The diagonal support plate 13 and the support frame 12 are plugged together to remind the support frame 12 that it has returned to its original position and cannot be moved.

[0036] A driving motor 14 is installed on the top of the supporting frame 12 , and a connecting frame 15 is installed on the output end of the driving motor 14 .

[0037] The side view of the support frame 12 is in an inverted "U" shape, and the top view of the connecting frame 15 is in a "U" shape. At the same time, the clamping elements 3 are located at both ends of the connecting frame 15. This layout facilitates multi-angle and all-round clamping and fixation of the motor, thereby ensuring safety and reliability during the maintenance process.

[0038] When using the tilting frame to overhaul a motor, the device is first firmly fixed in a suitable position by the diagonal support plate 13 to ensure the safety of the operation. Then, the position of the support frame 12 is adjusted by the built-in screw drive system to make it correspond to the optimal operating position of the motor to be overhauled.

[0039] Next, the drive motor 14 is started, and the motor is precisely clamped by the clamping element 3 on the connecting frame 15. Due to the unique design of the connecting frame 15 and the clamping element 3 (i.e., a "U" shape when viewed from above), the motor can be firmly clamped while allowing the motor to be rotated or flipped when necessary for comprehensive inspection and maintenance.

[0040] Throughout the entire process, the inverted "U"-shaped design of support frame 12 not only provides ample operating space for the motor but also ensures structural stability and robustness, preventing equipment damage or safety accidents caused by improper operation. Furthermore, by adjusting the screw drive system, the position of support frame 12 can be easily changed to meet the maintenance requirements of motors of different specifications, greatly improving work efficiency and flexibility.

[0041] The storage element 2 includes a hydraulic rod 21 arranged at the top of the base plate 11. A bracket platform 22 is installed at the end of the piston rod of the hydraulic rod 21. The bracket platform 22 is driven up and down by the hydraulic rod 21. The storage element 2 can effectively drive the maintenance motor to move to a suitable position for clamping.

[0042] Reference Figure 2-Figure 4 In one embodiment provided in the present application, the clamping arm 31 includes a telescopic cylinder 311 arranged on the outer wall of the connecting frame 15, and the piston rod of the telescopic cylinder 311 passes through the connecting frame 15 and is connected to the clamping block 312 so as to perform precise clamping according to the specific size of the motor.

[0043] The clamping block 312 is arranged in an "eight" shape. This unique shape can effectively adapt to the surfaces of motors of different sizes and shapes and provide a more stable clamping force. A buffer airbag 313 is provided in the middle position of the "eight" shape of the clamping block 312. The buffer airbag can play a buffering role during the clamping process to avoid damage to the motor.

[0044] The side walls of the clamping block 312 are mounted with tooth blocks 314, which are located at both ends of the side walls of the clamping block 312. A lower groove A is provided in the middle of the cushioning airbag 313, which is higher at both ends and lower in the middle. An arc-shaped groove B is provided in the middle of the two tooth blocks 314, wherein the height of the arc-shaped groove B is lower than the tooth blocks 314 at both ends. The contact surface between the clamping block 312 and the maintenance motor is made of rubber. This layout not only enhances the clamping force, but also provides additional space to accommodate the different external features of the motor. Furthermore, the side of the clamping block 312 that contacts the motor to be repaired is made of rubber, which increases friction and provides protection, preventing the motor surface from being scratched or damaged.

[0045] Reference Figure 4 In one embodiment of the present application, when using this clamping system to repair a motor, the telescopic cylinder 311 is first activated, and its piston rod pushes the clamping block 312 toward the motor. Because the clamping block 312 is designed in an "eight" shape, it can adaptively fit the motor housing, ensuring a secure clamp.

[0046] The cushioning airbag 313 plays a key role in the clamping process. As the clamping block 312 approaches the motor, the cushioning airbag 313 begins to compress, filling any gaps and absorbing the impact forces generated during the clamping process, effectively preventing mechanical damage caused by over-clamping. The design of the lower groove A further optimizes pressure distribution, making the entire clamping process smoother and safer.

[0047] The presence of tooth block 314 enhances the gripping ability of the clamping system, particularly for motors with irregular surfaces. The arcuate slot B provides additional room for the motor to maneuver, maintaining a certain degree of flexibility even in the clamped state, facilitating subsequent flipping and inspection operations. The rubber material used on the contact surface between clamping block 312 and the motor not only increases friction but also reduces the risk of wear that could result from direct metal-to-metal contact.

[0048] In short, this design fully takes into account the various needs during the motor maintenance process, and through clever structural design and material selection, it achieves efficient and safe motor clamping and flipping operations.

[0049] It should be noted that the device is fixed by the diagonal support plate 13, and then the motor to be repaired is placed at the top center position of the bracket platform 22, and then the screw on the base plate 11 is started to drive the clamping element 3 on the connecting frame 15 to move to the appropriate positions at both ends of the repair motor, and then the telescopic cylinder 311 is started, and the telescopic cylinder 311 drives the clamping block 312 to clamp and fix the repair motor. During the clamping and fixing process, the rubber material on the buffer airbag 313 and the clamping block 312 is used for buffering, reducing the damage to the motor caused by the clamping vibration and reducing the clamping wear. When the clamping block 312 clamps the motor, a compression force is generated so that the motor is located in the lower groove A. Due to the action of pressure, the arc groove B of the buffer airbag 313 is squeezed inward, causing the gas in the middle of the airbag to be compressed to both sides. Since the lower groove A and the arc groove B are higher than the two ends, the risk of anti-slip can be effectively reduced.

[0050] Reference Figure 5 In some implementations, this embodiment is different from other embodiments in that the clamping block 312 clamps the object by driving the clamping block 312 through the extrusion link 315 .

[0051] The previous embodiment uses the telescopic cylinder 311 to drive the clamping block 312 to move toward the maintenance motor, and the extrusion force squeezes the buffer airbag 313 so that the clamping block 312 moves closer to the middle to clamp the maintenance motor. Since both ends are driven by the telescopic cylinder 311 to squeeze the same distance, the buffer airbag 313 will not rebound and cause the clamping block 312 to fall off. However, since the position of the buffer airbag 313 squeezed by the maintenance motor is unstable, the clamping movement of the clamping block 312 is limited by the squeezing situation, resulting in sometimes one clamping surface of the clamping block 312 contacting the motor and the other not contacting.

[0052] Therefore, a connecting rod 315 is provided between the two clamping blocks 312 so that the distance between the two clamping blocks 312 is the same when they are close to each other, and the contact surface between the two clamping blocks 312 and the maintenance motor is larger, thereby improving the stability of the clamping.

[0053] Reference Figure 6 In some implementations, this embodiment differs from other embodiments in that the single connecting rod 315 is arranged as two connecting rods 315 side by side.

[0054] The inner rod 315b is hinged to the telescopic cylinder 311 through the intermediate rod 315c, while one end of the outer rod 315a is connected to the clamping block 312, and the other end is directly hinged to the telescopic cylinder 311 without passing through the intermediate rod 315c, thereby improving the stability of the connection of the clamping block 312.

[0055] Finally, it should be pointed out that the methods and devices described in detail above are merely embodiments, and those skilled in the art can modify these embodiments in different ways without departing from the scope of the present invention.
