Description

Technical Field

[0001] The invention relates to the field of rotor dynamic balancing, and in particular to a driving motor rotor cutting dynamic balancing processing device. Background Art

[0002] With the development of modern technology, many highly professional tools have emerged in different fields. The electric drill hammer is one of the commonly used tools in the field of construction and home improvement. The electric drill hammer can work well on the wall and drill installation holes of suitable sizes on the wall for various items and equipment to be fixed on the wall. The operating stability of the electric hammer drill is closely related to the first motor inside. During the manufacturing process, the center of gravity of the rotor of the first motor will be offset from the axis due to the uneven quality of the materials. The smaller the unbalanced mass, the greater the centrifugal force will be generated when the first motor rotates. The vibration will occur during the operation of the first motor, which will accelerate the wear of the bearings and shorten the life of the first motor.

[0003] In order to eliminate the imbalance caused by the center of gravity shift, the rotor needs to be dynamically balanced. The dynamic balancing method is generally to measure the imbalance position and imbalance weight through a dynamic balance machine, and use weighting or weight reduction methods, such as riveting washers on the rotor balance column or grinding the end face of the balanced rotor to eliminate the center of gravity shift. After balancing the weight, it is necessary to test again to determine the dynamic balance of the rotor.

[0004] The rotor assembly in the electric drill hammer that needs to be dynamically balanced includes a rotor body, a rotating shaft fixed on the rotor body, and heat dissipation fan blades arranged at the end of the rotating shaft. When the dynamic balance of the rotor assembly is tested by weight reduction, the surface of the rotor body needs to be ground, but grinding will produce waste chips, which will fly and cause the working environment to deteriorate. Summary of the invention

[0005] In order to improve the working environment of rotor dynamic balancing processing, the present application provides a driving motor rotor cutting dynamic balancing processing device.

[0006] The present application provides a driving motor rotor cutting dynamic balancing processing device adopts the following technical solution: A driving motor rotor cutting dynamic balancing processing device comprises a workbench, a center frame fixedly arranged on the workbench, and a moving device arranged on the center frame for moving a rotor assembly, wherein a preparation table, a first dynamic balancing test device, a dynamic balancing processing device, and a second dynamic balancing test device are sequentially arranged on the workbench around the center frame, wherein the preparation table is used to receive the rotor assembly, the first dynamic balancing test device is used to perform dynamic balancing detection on the rotor assembly before balancing processing, the dynamic balancing processing device performs balancing processing on the rotor by a grinding method, and the second dynamic balancing test device is used to perform dynamic balancing detection on the rotor assembly after balancing processing; The dynamic balancing processing device includes a first frame, a limit assembly, a grinding assembly and a waste chip collection assembly. The first frame is fixedly arranged on a workbench. The limit assembly is arranged on the first frame to control the rotor assembly to rotate to a grinding position and fix the rotor assembly. The grinding assembly is arranged on the first frame to perform fixed-point grinding on the outer wall of the rotor body of the rotor assembly. The waste chip collection assembly includes an open cover, an air pipe, a collection mesh bag and an air intake assembly. The open cover is located directly below the grinding position. The bottom end of the open cover is connected to the air pipe, one end of the air pipe is connected to the collection mesh bag, and the other end of the air pipe is connected to the air intake assembly.

[0007] By adopting the above technical solution, while the outer wall of the rotor is being ground, the air intake assembly ventilates into the air pipe, and the open mouth itself can be used to receive the waste chips generated by grinding. At the same time, since the bottom end of the open mouth is connected to the air pipe, the air flow velocity at the bottom of the open mouth is relatively large and the air pressure is relatively small, so the waste chips can be adsorbed into the air pipe, and the waste chips can enter the collection net bag along the air flow, thereby improving the working environment of the rotor dynamic balancing processing.

[0008] Preferably, the first dynamic balancing test device comprises a detection and analysis component, a second frame, a support frame, a first motor, a driving wheel, a moving block, a moving wheel, a transmission belt, a reset member, a brake member and a plurality of fixed wheels, the second frame is fixedly arranged on a workbench, the driving wheel and the plurality of fixed wheels are rotatably connected to the second frame, a transverse groove is provided on the second frame along a horizontal axis direction perpendicular to the driving wheel, the moving block is slidably connected in the transverse groove, the moving wheel is rotatably connected to the moving block, the rotation axis directions of the driving wheel, the fixed wheel and the moving wheel are horizontal and parallel to each other, and the transmission belt is wound around the driving wheel, the fixed wheel and the moving wheel; The support frame is fixedly arranged on the second frame body along the vertical direction, and the top end of the support frame is arranged in a V shape, and is used to receive the rotating shaft part of the rotor assembly, and the support frame is located between the rotor body and the heat dissipation fan blades of the rotor assembly; The portion of the transmission belt between the moving wheel and one of the fixed wheels is a receiving belt, and the receiving belt is used to receive the rotor assembly. The first motor drives the driving wheel to rotate. The reset member is used to drive the moving block to move until the receiving belt is always in a straight line tensioned state when there is no rotor assembly on the receiving belt. The brake member is used to lock the position of the moving block in the transverse groove when the transmission belt is running. The detection and analysis component includes a sensor for real-time detection of vibration signals of the rotor component during rotation, and a processor for analyzing and processing the detected vibration signals.

[0009] By adopting the above technical solution, the moving device moves the rotor assembly from the preparation table to the first dynamic balancing test device, the rotating shaft part of the rotor assembly abuts against the top of the support frame, and the rotor body part of the rotor assembly abuts against the transmission belt. Then the first motor drives the driving wheel to rotate and drive the transmission belt for transmission, and the transmission belt drives the rotor assembly to rotate to test the dynamic balance.

[0010] Preferably, the brake member comprises a damping elastic block, a plurality of first springs and a plurality of first centrifugal blocks, a slide groove is provided on the top surface of the moving block, the damping elastic block is slidably connected in the slide groove along the vertical direction, a movable groove connected to the slide groove is provided in the moving block, the end of the moving wheel is located in the movable groove, the end of the moving wheel located in the movable groove is uniformly provided with a plurality of first grooves along the circumferential direction, the length direction of the first groove is arranged along the radial direction of the moving wheel, a plurality of first centrifugal blocks are respectively slidably connected in the plurality of first grooves, a plurality of first springs respectively correspond to the plurality of first centrifugal blocks, and two ends of the first spring are respectively fixedly arranged on the corresponding first centrifugal block and on the corresponding first groove bottom wall; When the transmission belt stops transmitting, the first centrifugal block is located in the first groove, the bottom end of the damping elastic block abuts against the moving wheel, and a gap is left between the top end of the damping elastic block and the top wall of the transverse groove; when the transmission belt is transmitting, the first centrifugal block extends into the movable groove, the bottom end of the damping elastic block abuts against the first centrifugal block, and the top end of the damping elastic block abuts against the top wall of the transverse groove.

[0011] By adopting the above technical solution, when the transmission belt stops transmitting, the first centrifugal blocks are all located in the first groove under the action of the first spring. At this time, the damping elastic block moves down under the action of gravity and abuts on the moving wheel. The top of the damping elastic block does not directly contact the top wall of the transverse groove, so the damping elastic block will not affect the movement of the moving block in the transverse groove; when the transmission belt is transmitting, the moving wheel rotates, and the first centrifugal block overcomes the elastic force of the first spring under the action of centrifugal force and moves to the movable groove. At this time, a number of first centrifugal blocks will continuously act on the damping elastic block, driving the damping elastic block to move upward, and the damping elastic block abuts on the top wall of the transverse groove, and friction occurs between the damping elastic block and the top wall of the transverse groove, thereby fixing the position of the moving block in the transverse groove.

[0012] Preferably, the air intake assembly includes a cover body and a driving member, the end of the air pipe away from the collecting net bag is a hard end, the hard end is fixedly set on the second frame, the cover body includes a fixed ring sleeve, an elastic cloth and a plurality of arc frames, the fixed ring sleeve is sleeved and slidably connected to the hard end along a direction parallel to the rotation axis of the driving wheel, the driving member drives the fixed ring sleeve to slide, one end of the plurality of arc frames is evenly fixedly set on the fixed ring sleeve along the circumferential direction, the elastic cloth is fixedly set on the plurality of arc frames and the fixed ring sleeve, and the opening of the elastic cloth is set on the side facing the heat dissipation fan blade.

[0013] By adopting the above technical solution, when the rotor assembly is subjected to a dynamic balancing test, the rotation of the fan will generate airflow, and the airflow will enter the elastic cloth and finally enter the air duct. The driving member drives the fixed ring sleeve to move toward the side of the cooling fan blades, and the elastic cloth covers the cooling fan blades. The airflow generated by the cooling fan blades can better enter the air duct, thereby reducing the loss of wind force.

[0014] Preferably, the air intake assembly also includes a gear, a second driving member, a plurality of pull ropes and a plurality of through rings. The gear is coaxially connected to the fixed ring sleeve, the second driving member is used to drive the gear to rotate, and the plurality of through rings are evenly arranged on the fixed ring sleeve along the circumferential direction. The plurality of pull ropes correspond to the plurality of through rings respectively, and the plurality of pull ropes correspond to the plurality of arc frames respectively. One end of the pull rope is fixedly set at one end of the corresponding arc frame away from the fixed ring sleeve, and the other end of the pull rope is fixedly set on the gear after passing through the corresponding through ring, and the arc frame is made of a hard elastic material.

[0015] By adopting the above technical solution, the driving member 2 controls the tension state of the pull rope by rotating the driving gear, so that the arc frame can be pulled to open to different amplitudes. Since the larger the diameter of the rotor part of the rotor assembly means the higher the power, it is necessary to match the cooling fan blades with larger diameters. Therefore, by changing the opening amplitude of the arc frame, the elastic cloth can better match the diameter of the cooling fan blades and reduce the loss of wind force.

[0016] Preferably, the second driving member and the reset member are the same component, including a rack and a connecting rod, the two ends of the connecting rod are respectively fixed on the rack and the moving block, the rack is meshingly connected to the gear, and the arc frame opens as the diameter of the rotor placed on the transmission belt increases.

[0017] By adopting the above technical solution, when the rotor assembly is not placed on the transmission belt, under the action of the arc frame, the arc frame recovers its deformation, and drives the gear to rotate and reset through the pull rope. The rotation of the gear can drive the moving block to move through the rack and the connecting rod, so that the moving block is reset and the receiving belt is tensioned; when the rotor assembly is placed on the transmission belt, under the action of the gravity of the rotor assembly, the larger the diameter of the placed rotor assembly, the greater the bending amplitude of the receiving belt, and the moving block will also move toward one side of the rotor assembly. At this time, the moving block can drive the rack to move through the connecting rod, the movement of the rack drives the gear to rotate, and the rotation of the gear pulls the pull rope, so that the arc frame can be opened.

[0018] Preferably, the driving member 1 comprises a first ring, a second spring, a protrusion, a slider, a plurality of second centrifugal blocks and a plurality of third springs, the first ring is coaxially fixedly arranged on the hard end of the trachea, the first ring is located on the side of the fixed ring sleeve away from the elastic cloth, the second spring sleeve is arranged on the hard end, the two ends of the second spring are respectively arranged on the first ring and the fixed ring sleeve, and the second spring is used to drive the fixed ring sleeve to move toward the side away from the rotor assembly; The protrusion is fixedly arranged on the outer wall of the fixed ring sleeve, the slider is slidably connected to the second frame along a direction perpendicular to the axis of the driving wheel and the sliding direction of the fixed ring sleeve, and the slider and the protrusion are respectively provided with mutually matching inclined surfaces at one end close to each other; One end of the driving wheel extends to be arranged close to the slider, and the extending portion of the driving wheel is evenly provided with a plurality of second grooves along the circumferential direction, and the length direction of the second grooves is arranged along the radial direction of the driving wheel, and a plurality of second centrifugal blocks are respectively slidably connected in the plurality of second grooves, and a plurality of third springs respectively correspond to the plurality of second centrifugal blocks, and the two ends of the third spring are respectively fixedly arranged on the corresponding second centrifugal blocks and on the corresponding second groove bottom wall; When the driving wheel stops rotating, the two ends of the slider respectively abut against the inclined surface of the protrusion and the outer wall of the extended part of the driving wheel, and the elastic cloth is located on the outside of the heat dissipation fan blade; when the driving wheel rotates, the second centrifugal block drives the slider to move toward the side of the protrusion, and the elastic cloth moves toward the side of the heat dissipation fan blade to cover the heat dissipation fan blade.

[0019] By adopting the above technical solution, when the rotor assembly is placed on the transmission belt or removed from the transmission belt, the transmission belt is in a stopped state. At this time, under the action of the second spring, the elastic cloth can be moved to the outside of the rotor assembly, which can reduce the impact on the placement and removal of the rotor assembly; when the transmission belt is in a running state, the driving wheel rotates, and the second centrifugal block overcomes the elastic force of the third spring under the action of centrifugal force and moves out of the second groove, abuts on the slider, drives the slider to move toward one side of the protrusion, and then under the action of the inclined surface, the protrusion moves toward one side of the rotor assembly, and finally the elastic cloth can cover the heat dissipation fan blades to reduce the loss of wind force.

[0020] The technical effects of the present invention are mainly reflected in the following aspects: 1. In the present invention, while grinding the outer wall of the rotor, the air intake assembly ventilates into the air pipe, and the open mouth itself can be used to receive the waste chips generated by grinding. At the same time, since the bottom end of the open mouth is connected to the air pipe, the air flow velocity at the bottom end of the open mouth is relatively large and the air pressure is relatively small, so the waste chips can be adsorbed into the air pipe, and the waste chips can enter the collection net bag along the air flow, thereby improving the working environment of the rotor dynamic balancing processing; 2. When the rotor assembly of the present invention is subjected to a dynamic balancing test, the rotation of the fan generates airflow, which enters the elastic cloth and eventually enters the trachea. The driving member drives the fixed ring sleeve to move toward the side of the heat dissipation fan blades, and the elastic cloth covers the heat dissipation fan blades. The airflow generated by the heat dissipation fan blades can better enter the trachea, thereby reducing the loss of wind force. BRIEF DESCRIPTION OF THE DRAWINGS

[0049] Reference Figure 4 and Figure 5 When the rotor assembly 3 is subjected to a dynamic balancing test, the rotation of the fan generates airflow, which enters the elastic cloth 812 and finally enters the air pipe 49. The driving member 9 drives the fixed ring sleeve 811 to move toward the side of the heat dissipation fan blades 33, and the elastic cloth 812 covers the heat dissipation fan blades 33. The airflow generated by the heat dissipation fan blades 33 can better enter the air pipe 49, thereby reducing the loss of wind force.

[0050] Reference Figure 5 and Figure 6 The air intake assembly also includes a gear 82, a second driving member, a plurality of pull ropes 83 and a plurality of through rings 84. The gear 82 is coaxially connected to the fixed ring sleeve 811 for rotation. The second driving member is used to drive the gear 82 to rotate. The plurality of through rings 84 are evenly arranged on the fixed ring sleeve 811 along the circumferential direction. The plurality of pull ropes 83 correspond to the plurality of through rings 84 respectively. The plurality of pull ropes 83 correspond to the plurality of arc frames 813 respectively. One end of the pull rope 83 is fixedly arranged at one end of the corresponding arc frame 813 away from the fixed ring sleeve 811. The other end of the pull rope 83 passes through the corresponding through ring 84 and is fixedly arranged on the gear 82. The arc frame 813 is made of a hard elastic material, such as metal and plastic.

[0051] Reference Figure 5 and Figure 6 The driving member 2 controls the tension state of the pull rope 83 by rotating the driving gear 82, so that the arc frame 813 can be pulled to open to different amplitudes. Since the larger the diameter of the rotor part of the rotor assembly 3, the higher the power, it is necessary to match the cooling fan blades 33 with a larger diameter. Therefore, by changing the opening amplitude of the arc frame 813, the elastic cloth 812 can better match the diameter of the cooling fan blades 33 and reduce the loss of wind force.

[0052] Reference Figure 5 and Figure 6The driving member 2 and the reset member are the same component, including a rack 71 and a connecting rod 72. The two ends of the connecting rod 72 are respectively fixed on the rack 71 and the moving block 55. The rack 71 is meshed and connected to the gear 82. The arc frame 813 opens as the diameter of the rotor placed on the transmission belt 57 increases.

[0053] Reference Figure 5 and Figure 6 When the rotor assembly 3 is not placed on the transmission belt 57, under the action of the arc frame 813, the arc frame 813 recovers its deformation, and drives the gear 82 to rotate and reset through the pull rope 83. The rotation of the gear 82 can drive the moving block 55 to move through the rack 71 and the connecting rod 72, so that the moving block 55 is reset and the receiving belt 571 is tensioned; when the rotor assembly 3 is placed on the transmission belt 57, under the action of the gravity of the rotor assembly 3, the larger the diameter of the placed rotor assembly 3, the greater the bending amplitude of the receiving belt 571, and the moving block 55 will also move toward one side of the rotor assembly 3. At this time, the moving block 55 can drive the rack 71 to move through the connecting rod 72, and the movement of the rack 71 drives the gear 82 to rotate, and the rotation of the gear 82 pulls the pull rope 83, so that the arc frame 813 can be opened.

[0054] Reference Figure 4-Figure 6 and Figure 8 The driving member 9 includes a first ring 91, a second spring 92, a protrusion 93, a slider 94, a plurality of second centrifugal blocks 95 and a plurality of third springs 96. The first ring 91 is coaxially fixed on the hard end 491 of the trachea 49. The first ring 91 is located on the side of the fixed ring sleeve 811 away from the elastic cloth 812. The second spring 92 is sleeved on the hard end 491. The two ends of the second spring 92 are respectively arranged on the first ring 91 and the fixed ring sleeve 811. The second spring 92 is used to drive the fixed ring sleeve 811 to move toward the side away from the rotor assembly 3.

[0055] Reference Figure 4 and Figure 5 The protrusion 93 is fixedly arranged on the outer wall of the fixed ring sleeve 811, and the slider 94 is slidably connected to the second frame 51 along the axial direction perpendicular to the driving wheel 54 and the sliding direction of the fixed ring sleeve 811. The slider 94 and the protrusion 93 are respectively provided with mutually matching inclined surfaces at one end close to each other.

[0056] Reference Figure 4 and Figure 8 One end of the driving wheel 54 extends to be arranged near the slider 94, and a plurality of second grooves 541 are evenly opened in the extended portion of the driving wheel 54 along the circumferential direction. The length direction of the second grooves 541 is arranged along the radial direction of the driving wheel 54, and a plurality of second centrifugal blocks 95 are respectively slidably connected in the plurality of second grooves 541, and a plurality of third springs 96 respectively correspond to the plurality of second centrifugal blocks 95, and the two ends of the third springs 96 are respectively fixedly arranged on the corresponding second centrifugal blocks 95 and on the corresponding bottom wall of the second groove 541.

[0057] Reference Figure 4 and Figure 8 When the driving wheel 54 stops rotating, the two ends of the slider 94 respectively abut against the inclined surface of the protrusion 93 and the outer wall of the extended portion of the driving wheel 54, and the elastic cloth 812 is located on the outside of the heat dissipation blade 33; when the driving wheel 54 rotates, the second centrifugal block 95 drives the slider 94 to move toward the side of the protrusion 93, and the elastic cloth 812 moves toward the side of the heat dissipation blade 33 to cover the heat dissipation blade 33.

[0058] Reference Figure 4-Figure 6 and Figure 8 When the rotor assembly 3 is placed on the transmission belt 57 or removed from the transmission belt 57, the transmission belt 57 is in a stopped state. At this time, under the action of the second spring 92, the elastic cloth 812 can be moved to the outside of the rotor assembly 3, which can reduce the impact on the placement and removal of the rotor assembly 3; when the transmission belt 57 is in a running state, the driving wheel 54 rotates, and the second centrifugal block 95 overcomes the elastic force of the third spring 96 under the action of centrifugal force and moves out of the second groove 541, abuts on the slider 94, drives the slider 94 to move toward the side of the protrusion 93, and then under the action of the inclined surface, the protrusion 93 moves toward the side of the rotor assembly 3, and finally enables the elastic cloth 812 to cover the heat dissipation fan blades 33, reducing the loss of wind force.

[0059] Reference Figure 1 , Figure 4 and Fig. 9 There can be two air intake assemblies. If the two air intake assemblies act on the first dynamic balancing test device 5 and the second dynamic balancing test device 10 respectively, the first dynamic balancing test device 5 and the second dynamic balancing test device 10 have the same structure. If there is only one air intake assembly and the air intake assembly acts only on the first dynamic balancing test device 5, the reset member on the second dynamic balancing test device 10 needs to be replaced with a fourth spring 512. The fourth spring 512 is located in the transverse groove 511, and the two ends of the fourth spring 512 are respectively arranged on the end wall of the transverse groove 511 and on the moving block 55.

[0060] Of course, the above are only typical examples of the present application. In addition, the present application may have many other specific implementation methods. All technical solutions formed by equivalent replacement or equivalent transformation fall within the scope of protection required by the present application.
