Abstract
Description
Technical Field
[0001] This application relates to the field of machining technology, and in particular to a dynamic balancing testing device. Background Technology
[0002] In an electric motor, vibration during rotor rotation can significantly impact the motor's lifespan, reliability, and operational performance. During rotor production, factors such as uneven rotor material, processing and installation errors, and rotor structure can cause vibration during rotation. Therefore, after rotor production is completed, dynamic balancing is required to correct the imbalance and prevent vibration during rotation.
[0003] Currently, the dynamic balance of the rotor is tested using a dynamic balancing testing device. If the rotor fails the dynamic balance test, it is transferred to the processing area for processing, and the processed rotor is then re-tested for dynamic balance until it passes the dynamic balance test.
[0004] However, if the rotor fails the dynamic balance test, the rotor needs to be processed and tested multiple times. Therefore, the rotor needs to be transferred between the dynamic balance test device and the processing area multiple times, which takes a long time and reduces the production efficiency of the rotor. Furthermore, if the rotor to be tested is processed directly on the dynamic balance test device, the vibration generated during processing will damage the dynamic balance test device and reduce the detection accuracy of the dynamic balance test device.

[0008] In one possible implementation, the support subunit includes: two driven wheels; the axis of the driven wheels is parallel to the axis of the rotor to be tested; the driven wheels are used to support the rotor to be tested and rotate with the rotor to be tested under the action of external force to detect the dynamic balance of the rotor to be tested, wherein the two driven wheels are respectively located on both sides of the axis of the rotor to be tested.
[0009] In one possible implementation, the lifting unit includes: a third support member, a fourth support member, and at least one lifting rod; the third support member is connected to the bracket, the third support member and the fourth support member are connected through the at least one lifting rod, and the fourth support member is located between the third support member and the rotor to be tested; the lifting rod is used to drive the fourth support member to move away from the bracket, so that the fourth support member drives the rotor to be tested to move away from the bracket, and to drive the fourth support member to move closer to the bracket, so that the fourth support member drives the rotor to be tested to move closer to the bracket.
[0010] In one possible implementation, the lifting unit further includes: at least two abutting units; the abutting units are connected to the fourth support member; the abutting units are used to support the rotor to be tested when the rotor to be tested is separated from the support unit, so that the rotor to be tested can rotate under the action of external force.
[0011] In one possible implementation, the abutment unit is a sphere, and the number of abutment units is greater than or equal to 3; or, the abutment unit is a cylinder, and the axis of the abutment unit is parallel to the axis of the rotor to be tested.
[0012] In one possible implementation, the dynamic balancing detection device further includes: a control unit and control buttons; the control buttons are disposed on the bracket, and the control unit is connected to the power unit and the control buttons via a circuit; the control unit is configured to, when the first button of the control buttons is triggered, control the power unit to provide the lifting power to the lifting unit via the circuit, so that the lifting unit drives the rotor to be tested to move away from the bracket, and when the second button of the control buttons is triggered, control the power unit to stop providing the lifting power to the lifting unit via the circuit, so that the lifting unit drives the rotor to be tested to move closer to the bracket.

The support unit and the lifting unit are connected to the bracket. The support unit supports the rotor to be tested, allowing it to rotate under external force, thus enabling dynamic balancing testing of the rotor located on the support unit. Because of the lifting unit, the rotor to be tested can be driven to move away from the bracket. This allows processing operations (e.g., adjusting the dynamic balance of the rotor by placing balancing pads on it) to be performed after the rotor and support unit transition from a contact state to a separation state. Compared with existing technologies, since the rotor and support unit are separated during processing, the vibration generated by the processing operation will not damage the dynamic balancing testing device, thus improving its service life and testing accuracy. Furthermore, the lifting unit can drive the rotor to be tested closer to the bracket, allowing for re-dynamic balancing testing of the rotor after processing, eliminating the need to move the rotor and improving production efficiency. Furthermore, since the power unit provides processing power to the processing unit when the rotor to be tested and the support unit change from a contact state to a separation state, it can prevent the operator from processing the rotor to be tested through the processing unit when the rotor to be tested and the support unit are in contact, and further prevent the riveting vibration generated during the processing of the rotor to be tested from damaging the dynamic balance testing device.

[0030] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.
[0031] In the description of this application, it should be understood that the terms "center", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.
[0032] As mentioned earlier, vibration during rotor rotation in an electric motor can significantly impact its lifespan, reliability, and operational performance. During rotor production, factors such as uneven material composition, processing and installation errors, and rotor structure can cause vibration during rotation. Therefore, after rotor production, dynamic balancing is necessary to correct imbalances and prevent vibration. Currently, rotor dynamic balance is tested using a dynamic balancing device. If the dynamic balance test fails, the rotor is transferred to a processing area for machining, and the machined rotor undergoes dynamic balancing again until it passes. However, if the rotor fails dynamic balance, multiple machining and dynamic balancing tests are required, necessitating repeated transfers between the dynamic balancing device and the processing area. This is time-consuming and reduces production efficiency. Furthermore, directly machining the rotor on the dynamic balancing device can damage the device due to vibrations, reducing its accuracy.
[0033] This application provides a dynamic balancing testing device, which includes a bracket, a support unit, a lifting unit, a processing unit, and a power unit. The support unit and the lifting unit are connected to the bracket. The support unit supports the rotor to be tested, allowing it to rotate under external force, thereby enabling dynamic balancing testing of the rotor located on the support unit. The lifting unit drives the rotor to be tested away from the bracket, allowing processing operations to be performed on the rotor after it transitions from a contact state to a separation state (e.g., during the process). (A method is used to adjust the dynamic balance of the rotor under test by setting balancing shims on the rotor.) Compared with existing technologies, since the rotor under test is separated from the support unit during processing, the vibration generated during processing will not damage the dynamic balancing testing device. This improves the service life and accuracy of the dynamic balancing testing device. Furthermore, the lifting unit can drive the rotor under test closer to the support, allowing for re-balancing after processing, eliminating the need to move the rotor and improving production efficiency. Additionally, since the power unit provides processing power to the processing unit when the rotor under test changes from contact to separation with the support unit, it prevents operators from processing the rotor under test through the processing unit while it is in contact with the support unit, further preventing vibration from damaging the dynamic balancing testing device during processing.
[0034] It should be noted that the accompanying drawings in this application are only for the purpose of illustrative purposes and understanding of this embodiment, and are not intended to limit this application in any way. They are not necessarily drawn to scale.
[0035] The dynamic balancing testing device provided in the embodiments of this application will be described in detail below with reference to the accompanying drawings.
[0036] Figure 1 This is a schematic diagram of a dynamic balancing testing device provided in an embodiment of this application. The dynamic balancing testing device 10 can perform dynamic balancing testing on the rotor of a motor. Figure 1As shown, the dynamic balancing testing device 10 includes: a bracket 11, a support unit 12, a lifting unit 13, a processing unit 14, and a power unit 15. The lifting unit 13 and the support unit 12 are connected to the bracket 11. The power unit 15 is connected to the lifting unit 13 and the processing unit 14 respectively. The support unit 12 can support the rotor 20 to be tested, so that the rotor 20 to be tested can rotate under the action of external force to detect the dynamic balance of the rotor 20 to be tested. The lifting unit 13 can drive the rotor 20 to be tested to move away from the bracket 11, so that the rotor 20 to be tested and the support unit 12 can change from a contact state to a separation state, and drive the rotor 20 to be tested to move closer to the bracket 11, so that the rotor 20 to be tested and the support unit 12 can change from a separation state to a contact state.
[0037] The power unit 15 can provide lifting power to the lifting unit 13, and provide processing power to the processing unit 14 when the rotor 20 to be tested is separated from the support unit 12. The processing unit 14 can add counterweights to the rotor 20 to be tested under the drive of the processing power, so as to adjust the dynamic balance of the rotor 20 to be tested by the counterweights.
[0038] The dynamic balancing testing device 10 includes a bracket 11, a support unit 12, and a lifting unit 13. The support unit 12 is connected to the bracket 11. When dynamic balancing testing of the rotor 20 to be tested is required, the rotor 20 is placed on the bracket 11. At this time, the support unit 12 supports the rotor 20. Optionally, at least a part of the structure of the support unit 12 can rotate. When the support unit 12 supports the rotor 20 and the rotor 20 rotates under the action of an external force, the support unit 12 will not affect the rotation of the rotor 20 and will not affect the dynamic balancing test result. Optionally, the dynamic balancing testing device 10 also includes a dynamic balancing testing unit. The dynamic balancing testing unit can provide an external force to the rotor 20 to make it rotate. That is, the dynamic balancing testing unit can drive the rotor 20 to rotate. The dynamic balancing testing device 10 can determine the dynamic balancing test result based on the rotation parameters of the rotor 20.
[0039] The lifting unit 13 can drive the rotor 20 to be tested to move away from the support 11. In one example, the lifting unit 13 can partially rise, and the rising structure can lift the rotor 20 to be tested to move away from the support 11, so that the rotor 20 to be tested is no longer in contact with the support unit 12. The operator can then perform processing operations on the rotor 20 to be tested, which is no longer in contact with the support unit 12, such as adding weights through the processing unit 14, without affecting the dynamic balance testing device 10. Furthermore, the lifting unit 13 can drive the rotor 20 to be tested to move closer to the support 11. In one example, the lifting unit 13 can partially descend, and the descending structure can lift the rotor 20 to be tested to move closer to the support 11 until the rotor 20 to be tested is placed on the support 11. At this point, the support unit 12 and the rotor 20 to be tested are back in contact.
[0040] The dynamic balancing testing device 10 may also include a processing unit 14, which can process the rotor 20 to be tested under the drive of the processing power provided by the power unit 15. For example, the processing unit 14 can add balancing shims to the rotor 20 to adjust the dynamic balance of the rotor 20. Optionally, the processing unit 14 may include a riveting gun, which can rivet the balancing shims onto the rotor 20 to be tested.
[0041] The overall dynamic balancing test process is described below:
[0042] After the rotor 20 to be tested is produced, it is placed on the support 11, and the support unit 12 supports it. The rotor 20 rotates under external force, and its dynamic balance is checked by measuring its rotation parameters. If the dynamic balance of the rotor 20 passes the test, the dynamic balance test of the next rotor 20 is performed. If the dynamic balance of the rotor 20 fails the test, the power unit 15 provides lifting power to the lifting unit 13, causing the lifting unit 13 to drive the rotor 20 to move away from the support 11. The rotor 20 to be tested is moved from a contact state to a separation state with the support unit 12. At this time, since the rotor 20 to be tested is separated from the support unit 12, the power unit 15 provides processing power to the processing unit 14, so that the operator can adjust the dynamic balance of the rotor 20 to be tested through the processing unit 14. Then, the lifting unit 13 drives the rotor 20 to be tested to move towards the support 11, so that the rotor 20 to be tested and the support unit 12 are moved from a separation state to a contact state, and the dynamic balance test of the rotor 20 to be tested is carried out again until the dynamic balance of the rotor 20 to be tested is passed.
[0043] Optionally, the power unit 15 can provide lifting power to the lifting unit 13 via gas, and can also provide processing power to the processing unit 14 via gas.
[0044] In this embodiment, the dynamic balancing testing device 10 includes a bracket 11, a support unit 12, a lifting unit 13, a processing unit 14, and a power unit 15. The support unit 12 and the lifting unit 13 are connected to the bracket 11. The support unit 12 can support the rotor 20 to be tested, allowing the rotor 20 to rotate under external force, thereby enabling dynamic balancing testing of the rotor 20 located on the support unit 12 and realizing the dynamic balancing testing function. Because the lifting unit 13 is provided, it can drive the rotor 20 to be tested to move away from the bracket 11. Therefore, after the rotor 20 and the support unit 12 change from a contact state to a separation state, processing operations can be performed on the rotor 20 (e.g., in…). (A balancing shim is installed on the rotor 20 to adjust its dynamic balance.) Compared with the prior art, since the rotor 20 is separated from the support unit 12 during processing, the vibration generated by the processing operation will not damage the dynamic balancing detection device 10. This improves the service life and detection accuracy of the dynamic balancing detection device 10. Furthermore, the lifting unit 13 can drive the rotor 20 to move closer to the bracket 11. Therefore, after processing, the rotor 20 can be re-balanced after it transitions from a separated state to a contact state with the support unit 12, eliminating the need to move the rotor 20 and improving production efficiency. Moreover, since the power unit 15 provides processing power to the processing unit 14 when the rotor 20 transitions from a contact state to a separated state with the support unit 12, it prevents operators from processing the rotor 20 through the processing unit 14 while it is in contact with the support unit 12, further preventing vibration generated during processing from damaging the dynamic balancing detection device 10.
[0045] Figure 2 This is a schematic diagram of a bracket provided in an embodiment of this application. Figure 2 As shown, the bracket 11 includes a base plate 111, a first support member 112, and a second support member 113. The support unit 12 includes two support sub-units 121. The first support member 112 is connected to the first end of the base plate 111, and the second support member 113 is connected to the second end of the base plate 111. The first support member 112 and the second support member 113 are arranged opposite to each other. One support sub-unit 121 is connected to the first support member 112, and the other support sub-unit 121 is connected to the second support member 113. The lifting unit 13 is connected to the base plate 111 and is located between the first support member 112 and the second support member 113. The two support sub-units 121 are used to support the first end and the second end of the rotor 20 to be tested, respectively.
[0046] The bracket 11 includes a base plate 111, a first support member 112 and a second support member 113. The first support member 112 and the second support member 113 are respectively disposed at both ends of the base plate 111. Optionally, the first support member 112 and the second support member 113 are parallel and opposite to each other. It should be understood that the lifting unit 13 is located between the first support member 112 and the second support member 113. The lifting unit 13 can drive the rotor to be tested 20 to move towards or away from the support unit 12 by lifting a portion of the area between the first end and the second end of the rotor to be tested 20.
[0047] The support unit 12 may include two support subunits 121, which are respectively disposed on the first support member 112 and the second support member 113. When the support subunit 121 supports the rotor 20 to be tested, the rotor 20 to be tested does not contact the first support member 112 or the second support member 113. Optionally, the two support subunits 121 have the same structure. Optionally, such as Figure 2 As shown, the two support subunits 121 can be arranged opposite to each other. In another embodiment, the two support subunits 121 can be respectively arranged on the side of the first support member 112 away from the second support member 113 and on the side of the second support member 113 away from the first support member 112.
[0048] In this embodiment, the bracket 11 includes a base plate 111, a first support member 112 and a second support member 113. The support unit 12 includes two support sub-units 121. One support sub-unit 121 is connected to the first support member 112 and the other support sub-unit 121 is connected to the second support member 113. Thus, the two support sub-units 121 can support the two ends of the rotor 20 to be tested respectively, thereby supporting the rotor 20 to be tested and enabling the rotor 20 to be tested to rotate smoothly under the action of external force.
[0049] In one possible implementation, such as Figure 2 As shown, the support subunit 121 includes two driven wheels 1211. The axes of the two driven wheels 1211 are parallel to the axis of the rotor 20 to be tested. The two driven wheels 1211 can support the rotor 20 to be tested and rotate with the rotor 20 under the action of external force to detect the dynamic balance of the rotor 20 to be tested. The two driven wheels 1211 are located on both sides of the axis of the rotor 20 to be tested.
[0050] The support subunit 121 includes two driven wheels 1211. Since the support unit 12 includes two support subunits 121, the support unit 12 includes four driven wheels 1211. The driven wheels 1211 can rotate. When the support subunit 121 supports the rotor 20 to be tested, two driven wheels 1211 are in contact with one end of the rotor 20 to be tested, and the other two driven wheels 1211 are in contact with the other end of the rotor 20 to be tested. When the rotor 20 to be tested rotates under the action of external force, each driven wheel 1211 can rotate with the rotor 20 to be tested, so as to prevent the dynamic balance test of the rotor 20 to be tested from being affected. It should be understood that when the diameters of the cross sections at both ends of the rotor 20 to be tested are the same, that is, when the thickness at both ends is the same, the axes of the driven wheels 1211 included in the two support subunits 121 can be located on the same horizontal plane. When the diameters of the cross sections at both ends of the rotor 20 to be tested are different, that is, when the thickness at both ends is different, the axes of the driven wheels 1211 included in the two support subunits 121 can be located on different horizontal planes. However, the axes of the two driven wheels 1211 included in the same support subunit 121 are located on the same horizontal plane. Thus, when the rotor 20 to be tested is supported by the two support subunits 121, the axis of the rotor 20 to be tested can be parallel to the axis of the driven wheel 1211, ensuring that the rotor 20 to be tested can rotate smoothly.
[0051] In this embodiment, the support subunit 121 includes two driven wheels 1211. The axes of the two driven wheels 1211 are parallel to the axis of the rotor 20 to be tested. The two ends of the rotor 20 to be tested can be supported by the four driven wheels 1211 included in the two support subunits 121. Since the support subunit 121 is composed of two driven wheels 1211, the rotor 20 to be tested can rotate under the action of external force when the support subunit 121 supports the rotor 20 to be tested. Compared with fixed support, it will not affect the rotation of the rotor 20 to be tested, and thus will not affect the dynamic balance test result of the rotor 20 to be tested.
[0052] Figure 3 This is a schematic diagram of a lifting unit provided in an embodiment of this application, as shown below. Figure 3 As shown, the lifting unit 13 includes a third support member 131, a fourth support member 132 and at least one lifting rod 133. The third support member 131 is connected to the bracket 11. The third support member 131 and the fourth support member 132 are connected by at least one lifting rod 133. The fourth support member 132 is located between the third support member 131 and the rotor 20 to be tested.
[0053] The lifting rod 133 can drive the fourth support member 132 to move away from the bracket 11, so that the fourth support member 132 drives the rotor 20 to be tested to move away from the bracket 11, and can also drive the fourth support member 132 to move closer to the bracket 11, so that the fourth support member 132 drives the rotor 20 to be tested to move closer to the bracket 11. That is, the lifting direction of the lifting rod 133 is perpendicular to the base plate 111.
[0054] Optionally, the lifting rod 133 can be raised or lowered by gas.
[0055] It should be understood that Figure 3 An example including four lifting rods 133 is shown. When only one lifting rod 133 is included, the lifting rod 133 can be set at the center position of the third support member 131 and the fourth support member 132. When only two lifting rods 133 are included, the two lifting rods 133 can be set opposite to each other at the edge position of the third support member 131 and the fourth support member 132. The specific number of lifting rods 133 can be set as needed.
[0056] In this embodiment of the application, the lifting unit 13 includes a third support member 131, a fourth support member 132 and at least one lifting rod 133. The third support member 131 is connected to the base plate 111. The lifting rod 133 can drive the fourth support member 132 to move up and down, thereby driving the rotor 20 to be tested to move away from the bracket 11 or towards the bracket 11 through the fourth support member 132.
[0057] In one possible implementation, the lifting unit 13 further includes at least two abutting units 134, which are respectively connected to the fourth support member 132. The abutting units 134 can support the rotor to be tested 20 when the rotor to be tested 20 is separated from the support unit 12, so that the rotor to be tested 20 can rotate under the action of external force.
[0058] It should be understood that when the dynamic balance test of the rotor 20 fails, it may be necessary to adjust the balance weights of the rotor 20 in each direction. The lifting unit 13 can drive the fourth support member 132 to move away from the bracket 11, so that the fourth support member 132 drives the rotor 20 to change from a contact state to a separation state with the support unit 12. At this time, the rotor 20 is supported by at least two abutting units 134 set on the fourth support member 132. The abutting units 134 can rotate. When the rotor 20 is supported by the abutting units 134, the operator can apply external force to the rotor 20 to make it rotate, so that the operator can adjust the balance weights of the rotor 20 in each direction without moving the position.
[0059] In this embodiment, the lifting unit 13 further includes at least two abutting units 134, which are respectively connected to the fourth support member 132. The abutting units 134 can support the rotor 20 to be tested when it is separated from the support unit 12, so that the rotor 20 to be tested can rotate under the action of external force. The operator can process each position of the rotor 20 to be tested without moving the position, which can improve the efficiency of adjusting the balance weight of the rotor 20 to be tested.
[0060] In one possible implementation, the contact unit 134 is a sphere, and the number of contact units 134 is greater than or equal to 3; or, the contact unit 134 is a cylinder, and the axis of the contact unit 134 is parallel to the axis of the rotor 20 to be tested.
[0061] The abutment unit 134 can be a sphere. It should be understood that, since it is necessary to stably support the rotor 20 to be tested, when the abutment unit 134 is a sphere, at least three abutment units 134 are required. At least two abutment units 134 are provided on one side of the axis of the rotor 20 to be tested, and at least one abutment unit 134 is provided on the other side of the axis of the rotor 20 to be tested. Thus, the rotor 20 to be tested can be stably supported by at least three abutment units 134.
[0062] The contact unit 134 can also be a column. When the rotor 20 to be tested is a column, it can include at least two contact units 134, for example: Figure 3 The diagram shows a contact unit 134 comprising two pillars. When the contact unit 134 supports the rotor 20 to be tested, the side surface of the pillar abuts against the rotor 20. The contact unit 134 can rotate around its axis. It should be understood that, in order to stably support the rotor 20 to be tested, when the contact unit 134 is a pillar, at least one contact unit 134 is provided on one side of the axis of the rotor 20 to be tested, and at least one contact unit 134 is provided on the other side of the rotor 20 to be tested, and the axis of each contact unit 134 is parallel to the axis of the rotor 20 to be tested. Optionally, when the contact unit 134 comprises three or more pillars, the axes of the contact units 134 located on the same side of the axis of the rotor 20 to be tested coincide.
[0063] Optionally, in addition to being disposed on both sides of the axis of the rotor 20 to be tested, the abutment unit 134 can also be disposed between the rotor 20 to be tested and the fourth support member 132, that is, the abutment unit 134 can be disposed directly below the rotor 20 to be tested.
[0064] In this embodiment, the abutment unit 134 is a sphere, and the number of abutment units 134 is greater than or equal to 3. Alternatively, the abutment unit 134 is a cylinder, and the axis of the abutment unit 134 is parallel to the axis of the rotor 20 to be tested. This allows the rotor 20 to be tested to be supported stably. When the abutment unit 134 is a sphere or a cylinder, the abutment unit 134 can rotate. This allows the rotor 20 to be tested to be rotated under external force while being supported stably. This allows the operator to process each position of the rotor 20 to be tested without moving the operator, thereby improving the efficiency of adjusting the balance weight.
[0065] Figure 4 This is a schematic diagram of a dynamic balancing detection device including a control unit, provided in an embodiment of this application. Figure 4 As shown, the dynamic balancing detection device 10 also includes a control unit 16 and a control button 17. The control button 17 is mounted on the bracket 11, and the control unit 16 is connected to the power unit 15 and the control button 17 via wiring.
[0066] When the first button in the control button 17 is triggered, the control unit 16 can control the power unit 15 to provide lifting power to the lifting unit 13 through the line control, so that the lifting unit 13 drives the rotor 20 to be tested to move away from the bracket 11. When the second button in the control button 17 is triggered, the control unit 16 can control the power unit 15 to stop providing lifting power to the lifting unit 13 through the line control, so that the lifting unit 13 drives the rotor 20 to be tested to move closer to the bracket 11.
[0067] Optionally, the control unit 16 can also control the dynamic balance detection unit in the aforementioned embodiment, so that the dynamic balance detection unit applies an external force to the rotor 20 to be tested, causing the rotor 20 to rotate. The control unit 16 can also perform dynamic balance detection on the rotor 20 to be tested according to the rotation parameters of the rotor 20.
[0068] Optionally, the control unit 16 can be a programmable controller (PLC), a host, a server, etc.
[0069] In this embodiment, the dynamic balancing detection device 10 further includes a control unit 16 and a control button 17. When the first button in the control button 17 is triggered, the control unit 16 controls the power unit 15 to provide lifting power to the lifting unit 13 through the connection line. When the second button in the control button 17 is triggered, the control unit 16 controls the power unit 15 to stop providing lifting power to the lifting unit 13 through the connection line. Thus, the lifting unit 13 can drive the rotor 20 to be tested to move away from the support 11 or drive the rotor 20 to be tested to move closer to the support 11. The operator can trigger the control button 17 according to the usage requirements to make the lifting unit 13 move according to the usage requirements.
[0070] In one possible implementation, the dynamic balancing detection device 10 further includes a valve 142 (see [reference]). Figure 5 As shown in the example, valve 142 is connected to control unit 16 via a line. Control unit 16 is used to open valve 142 via a line when the rotor 20 to be tested and the support unit 12 change from a contact state to a separation state, so that power unit 15 provides processing power to processing unit 14, and to close valve 142 via a line when the rotor 20 to be tested and the support unit 12 change from a separation state to a contact state, so that power unit 15 stops providing processing power to processing unit 14.
[0071] The dynamic balancing testing device 10 also includes a valve 142. The valve 142 can be installed in the pipeline between the power unit 15 and the processing unit 14. The valve 142 can also be installed inside the power unit 15. When the valve 142 is open, the power unit 15 provides processing power to the processing unit 14. When the valve 142 is closed, the power unit 15 stops providing processing power to the processing unit 14.
[0072] Optionally, valve 142 may include a solenoid valve. When the first button in control button 17 is triggered, control unit 16 can send an electrical signal to valve 142 via a line, and valve 142 opens. When the second button in control button 17 is triggered, control unit 16 can stop sending electrical signals to valve 142 via a line, and valve 142 closes. It should be understood that when the first button in control button 17 is triggered, lifting unit 13 drives the rotor 20 to be tested to move away from support 11. At this time, the rotor 20 to be tested and support unit 12 change from a contact state to a separation state, and valve 142 opens. When the second button in control button 17 is triggered, lifting unit 13 drives the rotor 20 to be tested to move closer to support 11. At this time, the rotor 20 to be tested and support unit 12 change from a separation state to a contact state, and valve 142 closes.
[0073] In this embodiment, the dynamic balancing testing device 10 further includes a valve 142, which is connected to a control unit 16 via a line. The control unit 16 controls the valve 142 to open when the rotor 20 to be tested and the support unit 12 change from a contact state to a separation state, and controls the valve 142 to close when the rotor 20 to be tested and the support unit 12 change from a separation state to a contact state. Thus, the power unit 15 can be controlled by the valve 142 to provide processing power to the processing unit 14. Since the valve 142 is open when the rotor 20 to be tested and the support unit 12 change from a contact state to a separation state, and the power unit 15 provides air-source riveting processing power to the processing unit 14, it can prevent the operator from riveting the rotor 20 to be tested by the processing unit 14 when the rotor 20 to be tested is in contact with the support unit 12, and prevent the riveting vibration generated during the processing of the rotor 20 to be tested from damaging the dynamic balancing testing device 10.
[0074] In one possible implementation, the power unit 15 is connected to the lifting unit 13 via the first pipe 135, and the power unit 15 is connected to the processing unit 14 via the second pipe 141. The valve 142 is disposed in the second pipe 141, or the valve 142 is disposed between the second pipe 141 and the power unit 15.
[0075] like Figure 1 As shown, the power unit 15 can provide lifting power to the lifting unit 13 through the first pipe 135, and the power unit 15 can provide processing power to the processing unit 14 through the second pipe 141. In one example, both the lifting power and the processing power can be formed by the power unit 15 compressing gas.
[0076] Optionally, valve 142 is disposed in the second pipe 141, or valve 142 is disposed between the second pipe 141 and the power unit 15, for example: Figure 5 This is a schematic diagram of a valve provided in an embodiment of this application, as shown below. Figure 5 As shown, valve 142 can be installed within the second pipe 141. In another embodiment, valve 142 can also be installed within the processing unit 14, or valve 142 can also be installed within the power unit 15. It should be understood that... Figure 5 This illustration only shows a configuration where valve 142 can be located within the second pipe 141; the specific location of valve 142 can be set as needed. Valve 142 can be opened or closed according to an electrical signal from control unit 16, so that when the rotor 20 to be tested is separated from the support unit 12, power unit 15 provides processing pneumatic power to processing unit 14 through the second pipe 141, and when the rotor 20 to be tested is in contact with the support unit 12, power unit 15 stops providing processing pneumatic power to processing unit 14.
[0077] In this embodiment, the power unit 15 is connected to the lifting unit 13 via the first pipe 135 and to the processing unit 14 via the second pipe 141. Thus, the power unit 15 can provide lifting power to the lifting unit 13 via the first pipe 135 and processing power to the processing unit 14 via the second pipe 141. This allows the lifting unit 13 to drive the rotor 20 under the lifting power and the processing unit 14 to add weights to the rotor 20 under the processing power. A valve 142 is located in the second pipe 141, or between the second pipe 141 and the power unit 15. This allows the valve 142 to control the power unit 15 to provide processing power to the processing unit 14. This enables the power unit 15 to provide processing power to the processing unit 14 when the rotor 20 is separated from the support unit 12, and to stop providing processing power to the processing unit 14 when the rotor 20 is in contact with the support unit 12. This prevents the riveting vibration generated during the processing of the rotor 20 from damaging the dynamic balance testing device 10.
