Description

Technical Field

[0001] This utility model belongs to the field of material transfer technology, and in particular relates to a motor shaft transfer box. Background Technology

[0002] In the motor manufacturing industry chain, the motor shaft, as the core transmission component of the motor, plays a crucial role in transmitting torque and supporting the rotor core. Its precision (such as coaxiality, cylindricity, and surface roughness) directly determines the motor's operational stability, noise level, and service life. After the motor shaft is fitted with the rotor core, it needs to be transferred through a product box to avoid damage to the motor shaft and the rotor core fitted on it.

[0003] Currently, most motor shaft transfer boxes widely used in the industry are traditional rectangular box structures, mainly made of plastic, paper or metal. Their design is only intended to meet the basic function of "accommodating motor shafts". The overall structure is relatively simple. The product box lacks a device to position and fix the motor shaft and a buffer mechanism to reduce vibration. As a result, during the transfer process, the motor shafts inside the box are prone to colliding with each other, which can damage the rotor core on the motor shaft. Utility Model Content

[0004] In view of the technical problems existing in the background art, the present invention provides a motor shaft transfer box.

[0005] To achieve the above objectives, the technical solution provided by this utility model is as follows: A motor shaft transfer box includes a main body and a fixing mechanism. The main body includes a box body and a box cover. A steel plate is fixedly connected to the bottom of the box body. A pair of damping rods are fixedly connected to both sides of the top of the steel plate. A bearing plate is fixedly connected to the top of the four damping rods. Several slots are provided on the bearing plate. The fixing mechanism includes multiple pairs of slide rods, each pair of slide rods is respectively set on one side of several slots, the bottom end of each pair of slide rods is slidably inserted into the bearing plate, and the top end of each slide rod is rotatably connected to a fixing plate for fixing the workpiece.

[0006] Optionally, a fixing bracket is provided between each pair of slide rods, and an adjusting screw is threadedly connected to the center of the fixing bracket.

[0007] Optionally, the bottom end of each adjusting screw is rotatably connected to the bearing plate, and the top end of each adjusting screw is fitted with a knob.

[0008] Optionally, the bottom of each fixing plate is equipped with a cushioning pad, which is made of rubber.

[0009] Optionally, the top surface of the support plate is fitted with a rubber protective pad on the outside of the slot, and the axis of the rubber protective pad is on the same vertical line as the axis of the slot.

[0010] Optionally, springs are fitted on the outer side of the damping rods, with the upper and lower ends of the springs fixedly connected to the bottom end of the bearing plate and the top end of the steel plate, respectively.

[0011] Optionally, a first nylon strip is fixedly connected to the center of the top surface of the support plate along its length direction, and a pair of second nylon strips are fixedly connected to the top surface of the support plate along its width direction, with the first and second nylon strips being staggered.

[0012] This utility model has the following advantages and beneficial effects: The main body of the box and the lid are interference-fitted to form a closed storage space, protecting the motor shaft from external dust and impacts. The steel plate inside the box strengthens the bottom support, and the damping rod, together with the bearing plate, can buffer vibrations during transportation to prevent damage to the motor shaft. The slots on the bearing plate are used to position the motor shaft and prevent it from shaking inside the box. The sliding rod of the fixing mechanism moves the fixing plate up and down, which can fix the top of the rotor core on the motor shaft, further limiting the displacement of the motor shaft. The rotating fixing plate allows the user to adjust its angle, making it easy to fix the rotor core on the motor shaft. The whole system achieves stable storage and transportation of the motor shaft, ensuring the integrity of the product. Attached Figure Description

[0015] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of this utility model, but not all embodiments.

[0016] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0017] Example like Figures 1-6 As shown, it includes a main body 1 and a fixing mechanism 2. The main body 1 includes a box body 101 and a box cover 102. A steel plate 108 is fixedly connected to the bottom of the box body 101. A pair of damping rods 109 are fixedly connected to both sides of the top of the steel plate 108. A bearing plate 103 is fixedly connected to the top of the four damping rods 109. Several slots 104 are provided on the bearing plate 103. The fixing mechanism 2 includes multiple pairs of slide rods 201. Each pair of slide rods 201 is respectively disposed on one side of several slots 104. The bottom end of each pair of slide rods 201 is slidably inserted into the bearing plate 103, and the top end of each slide rod 201 is rotatably connected to a fixing plate 202 for fixing the workpiece.

[0018] Furthermore, a fixing frame 203 is provided between each pair of slide rods 201. An adjusting screw 204 is threadedly connected to the center of the fixing frame 203. The fixing frame 203 connects each pair of slide rods 201 into a whole, ensuring that each pair of slide rods 201 rises and falls synchronously, so that the fixing plate 202 is evenly stressed. The adjusting screw 204 is threadedly connected to the fixing frame 203. Rotating the adjusting screw 204 can drive the fixing frame 203 and slide rods 201 to move up and down, accurately adjusting the height of the fixing plate 202 to meet the fixing requirements of different motor shaft rotor core heights.

[0019] Furthermore, the bottom end of each adjusting screw 204 is rotatably connected to the support plate 103, and the top end of each adjusting screw 204 is fitted with a knob 205. The bottom end of the adjusting screw 204 is rotatably connected to the support plate 103 to ensure that when the adjusting screw 204 rotates, it only drives the fixed frame 203 to move, avoiding its own deviation. The knob 205 at the top provides an easy point of force for the operator, allowing the adjusting screw 204 to be rotated without special tools, simplifying the fixing operation steps and improving ease of use.

[0020] Furthermore, the bottom of the fixing plate 202 is provided with a buffer pad made of rubber. The rubber buffer pad at the bottom of the fixing plate 202 can prevent the fixing plate 202 from rigidly contacting the rotor core sleeved on the motor shaft, thus preventing damage to the surface of the rotor core.

[0021] Furthermore, the top surface of the support plate 103 is fitted with rubber protective pads 105 on the outside of the slot 104. The axis of the rubber protective pads 105 and the axis of the slot 104 are on the same vertical line. The rubber protective pads 105 on the outside of the slot 104 can protect the bottom end of the rotor core fitted on the motor shaft and reduce frictional damage between the motor shaft and the support plate 103. The elasticity of the rubber material can also fill the gap between the motor shaft and the slot 104, further limiting the radial sway of the motor shaft and improving storage stability.

[0022] Furthermore, springs 110 are fitted on the outer side of each damping rod 109. The upper and lower ends of the springs 110 are fixedly connected to the bottom end of the bearing plate 103 and the top end of the steel plate 108, respectively. The springs 110 on the outer side of the damping rod 109 can work together with the damping rod 109 to enhance the buffering effect and further absorb vibration energy during transportation bumps, preventing vibration from being transmitted to the motor shaft. At the same time, the springs 110 can assist the bearing plate 103 in resetting, ensuring that the bearing plate 103 always maintains a stable posture and protecting the motor shaft from impact.

[0023] Furthermore, a first nylon strip 106 is fixedly connected to the center of the top surface of the support plate 103 along its length direction, and a pair of second nylon strips 107 are fixedly connected to the top surface of the support plate 103 along its width direction. The first nylon strip 106 and the second nylon strip 107 are staggered. The staggered arrangement of the first nylon strip 106 and the second nylon strip 107 on the support plate 103 can separate the space of the support plate 103.

[0024] Specifically, the working principle of this type of motor shaft transfer box is as follows: In use, first open the cover 102, which is interference-fitted with the box body 101. Insert one end of the motor shaft, which houses the rotor core, into the slot 104 of the support plate 103. The rubber protective pad 105 on the outside of the slot 104 fits against the bottom of the rotor core, reducing friction and limiting radial movement of the motor shaft. Next, rotate the knob 205 at the top of the adjusting screw 204, causing the adjusting screw 204 to rotate on the support plate 103. This causes the screw to connect with the fixed frame 203 via a thread, driving the fixed frame 203 and the slide rod 201 along... The support plate 103 slides down, and at the same time, the fixed plate 202 at the top of the slide bar 201 is rotated to adjust the angle until the rubber buffer pad at the bottom of the fixed plate 202 is in contact with the top of the rotor core. Continue to rotate the knob 205 to make the fixed plate 202 stably clamp the rotor core. After the box cover 102 is closed, if vibration occurs during transportation, the damping rod 109 on the steel plate 108 inside the box 101 and the outer spring 110 work together to absorb the vibration energy and assist the support plate 103 to reset, preventing the vibration from being transmitted to the motor shaft. The whole system achieves stable storage and safe transportation of the motor shaft.

[0025] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
