Description

Technical Field

[0001] The utility model belongs to the technical field of motor production, and particularly relates to a rotor elastic shock absorption device for motor production. Background Art

[0002] A motor, also known as an electric motor or engine, is an electrical device that converts electrical energy into mechanical energy. The rotor is a key component responsible for rotation in the motor and is the dynamic part in the energy conversion process of the motor. Currently, after the motor rotors are produced, they need to be collected uniformly.

[0003] In the existing production, the motor rotors all fall from the production area into the collection area. There is a large drop between the production area and the collection area. Merely through an inclined transmission channel, the speed and impact force of the motor rotors cannot be effectively reduced. This makes the motor rotors prone to collision and damage during the falling process, resulting in a decrease in the finished product rate and an increase in defective products. Content of the Utility Model

[0004] In view of this, the utility model provides a rotor elastic shock absorption device for motor production, which can absorb and release the energy of the vibration impact of the motor rotor through an elastic shock absorption mechanism, avoid the motor rotor from directly falling from the production area and causing bumps and damages to the motor rotor, meet the requirements of elastic shock absorption for motor rotors of different weights, greatly improve the applicable range, and can gradually decelerate and weaken the impact force of the rotor.

[0005] To solve the above technical problems, the utility model provides a rotor elastic shock absorption device for motor production, including a blanking plate and an elastic shock absorption mechanism arranged at the lower end of the blanking plate. The elastic shock absorption mechanism includes a shock absorption plate rotatably connected to the lower end of the blanking plate for shock-absorbing the motor rotor. At the lower ends of the front and back surfaces of the shock absorption plate, there are longitudinally symmetrically distributed rotating blocks I rotatably connected. At the lower ends of the front and back surfaces of the blanking plate, there are longitudinally symmetrically distributed sliding grooves. Sliders are slidably connected in the sliding grooves, and the sliding grooves provide guiding and moving support for the sliders. In the middle of the outer surfaces of the sliders, there are rotating blocks II rotatably connected. Springs are arranged between the rotating blocks II and the adjacent rotating blocks I on the same side. The rotating blocks II and the rotating blocks I cooperate to support the springs, and the springs play a buffering role. At the lower sides of the front and back surfaces of the shock absorption plate, there are longitudinally symmetrically distributed rotating columns I rotatably connected. At the lower sides of the front and back surfaces of the blanking plate, there are longitudinally symmetrically distributed rotating columns II rotatably connected. Damping rods are arranged between the rotating columns II and the adjacent rotating columns I on the same side. The rotating columns II and the rotating columns I cooperate to support the damping rods, and the damping rods can reduce vibration and impact force.

[0006] In the middle between the upper and lower wall surfaces of the sliding grooves, there are screw rods rotatably connected. The screw rods are respectively threadedly connected to the screw holes arranged in the middle of the sliders on the same side. The screw rods are used to drive the sliders and their affiliated mechanisms to move. At the front and back ends of the lower side of the blanking plate, there are notches corresponding to the upper ends of the screw rods one by one.

[0007] Scale lines are provided on the lower sides of the front and rear surfaces of the blanking plate near each chute, facilitating observation by the operator.

[0008] A rubber plate is provided in the middle of the upper surface of the shock-absorbing plate to further buffer using the characteristics of the material.

[0009] A plurality of buffer plates are alternately and obliquely arranged on the front and rear wall surfaces of the blanking plate. The buffer plates are all inclined downward from outside to inside, which plays a role in slowing down the downward movement speed and impact force when the motor rotor moves.

[0010] Anti-slip covers are provided at the lower ends of the left and right surfaces of the blanking plate and are longitudinally symmetrically distributed. The shock-absorbing plates, rotating block one, chute, slider, rotating block two, spring, rotating column one, rotating column two, damping rod, lead screw, and scale lines in the same side are respectively located within the adjacent anti-slip covers on the same side, which can play a role in safety protection for the internal mechanism.

[0011] The beneficial effects of the above technical solutions of the present utility model are as follows:

[0012] 1. The initially buffered motor rotor continues to move downward and finally contacts the shock-absorbing plate. At this time, the shock-absorbing plate receives the impact force of the motor rotor, and the shock-absorbing plate immediately transmits the impact shock force to the spring through the rotating block one. The spring cooperates with the rotating block two and buffers and reduces the vibration impact through its own elastic stretching action. At the same time, the damping rod extends through the cooperation of the rotating column one and the rotating column two, thereby converting and dissipating the vibration energy into heat. The shock-absorbing system composed of the spring and the damping rod absorbs and releases the vibration impact of the motor rotor, avoiding the motor rotor from directly falling in the production area and causing damage to the motor rotor due to knocking.

[0013] 2. When elastic shock absorption is required for motor rotors of different weights, the operator rotates the lead screw. The rotation of the lead screw drives the slider to move along the chute. When the slider moves, it pulls the spring, causing the spring to be stretched, thereby changing its pre-tightening state. At the same time, the damping force of the damping rod is synchronously adjusted, and then the elastic shock-absorbing force of the entire system is adjusted. The scale line can visually observe the distance moved by the slider and maintain its synchronism, meeting the requirements of elastic shock absorption for motor rotors of different weights and greatly improving the applicable range.

[0014] 3. The rubber plate uses the characteristics of its own material to protect the motor rotor from direct impact and prevent its surface from being scratched.

[0015] 4. The produced motor rotor enters from above the blanking plate and then passes through each layer of buffer plates in sequence for buffering, which can gradually decelerate and weaken the impact force of the rotor. Description of the Drawings

At the lower ends of the front and rear surfaces of the blanking plate 100, chutes 202 symmetrically distributed longitudinally are provided. Sliders 203 are slidably connected in the chutes 202, and the chutes 202 provide guiding and moving support for the sliders 203. Second rotating blocks 204 are rotatably connected to the middle parts of the outer surfaces of the sliders 203. Second rotating grooves for rotatably supporting the second rotating blocks 204 are provided at the middle parts of the outer surfaces of the sliders 203. Springs 205 are provided between the second rotating blocks 204 and the adjacent first rotating blocks 201 on the same side. The second rotating blocks 204 and the first rotating blocks 201 cooperate to support the springs 205, and the springs 205 play a buffering role. At the lower sides of the front and rear surfaces of the shock-absorbing plate 200, first rotating columns 206 symmetrically distributed longitudinally are rotatably connected. Third rotating grooves for rotatably supporting the second rotating blocks 204 are provided at the middle parts of the outer surfaces of the sliders 203. At the lower sides of the front and rear surfaces of the blanking plate 100, second rotating columns 207 symmetrically distributed longitudinally are rotatably connected. Fourth rotating grooves for rotatably supporting the second rotating columns 207 are provided at the lower sides of the front and rear surfaces of the blanking plate 100. Damper rods 208 are provided between the second rotating columns 207 and the adjacent first rotating columns 206 on the same side. The second rotating columns 207 are welded to the cylinder ends of the adjacent damper rods 208 on the same side, and the first rotating columns 206 are welded to the telescopic ends of the adjacent damper rods 208 on the same side. The second rotating columns 207 and the first rotating columns 206 cooperate to support the damper rods 208, and the damper rods 208 can reduce vibration and impact force.

[0024] As Figures 2-3 shown, lead screws 300 are rotatably connected to the middle parts between the upper and lower wall surfaces of the chutes 202. Rotating grooves for rotatably supporting the lead screws 300 are provided at the middle parts between the upper and lower wall surfaces of the chutes 202. The lead screws 300 are respectively threadedly connected to threaded holes provided in the middle parts of the adjacent sliders 203 on the same side. The lead screws 300 are used to drive the sliders 203 and their attached mechanisms to move. Notches corresponding to the upper ends of the lead screws 300 one by one are provided at the front and rear ends of the lower side of the blanking plate 100.

[0025] As Figures 2-3 shown, scale lines 400 are provided at the lower sides of the front and rear surfaces of the blanking plate 100 near each chute 202, which is convenient for the operator to observe.

[0026] As Figures 1-4As shown in the figure, a rubber plate 500 is provided in the middle of the upper surface of the shock-absorbing plate 200. A slot for fixedly installing the rubber plate 500 is provided in the middle of the upper surface of the shock-absorbing plate 200, and further buffering is carried out by using the characteristics of the material.

[0027] As Figures 1-4 shown, a plurality of buffer plates 600 are alternately inclined on the front and rear wall surfaces of the blanking plate 100. The buffer plates 600 are all inclined downward from the outside to the inside, which plays a role in slowing down the downward movement speed and impact force when the motor electronics move.

[0028] The working principle of a rotor elastic shock-absorbing device for motor production provided by the present utility model is as follows: The produced motor rotor enters from above the blanking plate 100, and then passes through each layer of buffer plates 600 in sequence for buffering, which can gradually decelerate and weaken the impact force of the rotor. The preliminarily buffered motor rotor continues to move downward and finally contacts the shock-absorbing plate 200. At this time, the shock-absorbing plate 200 receives the impact force of the motor rotor, and the shock-absorbing plate 200 immediately transmits the impact shock force to the spring 205 through the rotating block 1 201. The spring 205 cooperates with the rotating block 2 204 to buffer and reduce the vibration shock through its own elastic stretching action. At the same time, the damping rod 208 extends through the cooperation of the rotating column 1 206 and the rotating column 2 207, so as to convert and dissipate the vibration energy into heat. The shock-absorbing system composed of the spring 205 and the damping rod 208 absorbs and releases the vibration shock of the motor rotor, avoiding the motor rotor from directly falling from the production area and causing the motor rotor to be bumped and damaged. When it is necessary to carry out elastic shock absorption on motor rotors of different weights, the operator rotates the screw rod 300, and the rotation of the screw rod 300 drives the slider 203 to move along the chute 202. When the slider 203 moves, it pulls the spring 205, so that the spring 205 is stretched, thereby changing its pre-tightening state. At the same time, the damping force of the damping rod 208 is synchronously adjusted, and then the elastic shock-absorbing force of the whole system is adjusted. The scale line 400 can directly observe the distance that the slider 203 moves, maintain its synchronism, meet the requirements of elastic shock absorption of motor rotors of different weights, greatly improve the applicable range, and the rubber plate 500 uses the characteristics of its own material to protect the motor rotor from direct impact and prevent its surface from being scratched.

[0029] As Figures 1-4As shown, anti-slip covers 700 are longitudinally and symmetrically arranged at the lower ends of the left and right surfaces of the blanking plate 100. The anti-slip covers 700 are fixedly installed at the lower ends of the left and right surfaces of the blanking plate 100 by bolts. The shock-absorbing plates 200, the first rotating blocks 201, the chutes 202, the sliders 203, the second rotating blocks 204, the springs 205, the first rotating columns 206, the second rotating columns 207, the damping rods 208, the lead screws 300 and the scale lines 400, which are in a group on the same side, are respectively located in the adjacent anti-slip covers 700 on the same side, and can play a role in protecting the internal mechanisms. The setting of the anti-slip covers 700 ensures that each component will not be affected by external factors during operation, maintaining the stability and safety of the overall system.

[0030] In addition, it should be noted that in the description of the present invention, unless otherwise clearly defined and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

It should be pointed out that for those of ordinary skill in the art, without departing from the principle described in the present invention, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present invention.
