DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] Example 1:

[0022] like Figure 1-Figure 7 As shown, the utility model provides an automatic motor virtual position measuring device with controllable force measurement, including a machine base 1, on which a support plate 2 is fixedly mounted, a slide rail 3 and a first cylinder 4 are fixedly mounted, a push seat 5 is movably mounted on the slide rail 3, and the first cylinder 4 is drivingly connected to the push seat 5, the push seat 5 is movably mounted with a top seat 6, the push seat 5 is fixedly mounted with a measuring cylinder 7, and the measuring cylinder 7 is drivingly connected to an ejector pin 8, the support plate 2 is fixedly mounted with a motor base 9 and a support 10, and the support 10 is fixedly mounted with a measuring gauge 11. The support plate 2 is fixedly mounted with a clamping cylinder 12, and the clamping cylinder 12 is drivingly connected to a clamping block 13. The motor base 9 is fixedly mounted with a baffle 14, and the baffle 14 is provided with a U-shaped groove 15. The top seat 6 is provided with an assembly hole 16, and the assembly hole 16 abuts against the push seat 5 via a spring 17. The support plate 2 is fixedly mounted with a second cylinder 18, and the second cylinder 18 is drivingly connected to an adjustment seat 19, and the adjustment seat 19 is fixedly mounted with a limit block 20. A control box 21 is fixedly mounted on the base 1 , and a display screen 22 and control buttons 23 are fixedly mounted on the control box 21 .

[0023] Through the above technical solution, the utility model fixes the motor to be tested by cooperating with the motor seat 9 and the top seat 6, and the probe force of the measuring gauge 11 pushes the rotor shaft core of the motor to one side, and then starts the measuring cylinder 7 to drive the top pin 8 to push the shaft core of the motor to be tested, so that the rotor shaft core of the motor moves to the other side. The measuring gauge 11 automatically displays the displacement values ​​at both ends, and the equipment automatically calculates the change in displacement, which is the virtual position value of the measured motor. In this process, according to different models of motors, by controlling the driving pressure of the measuring cylinder 7, the force in the measurement process is controlled to improve the measurement accuracy. The motor virtual position measurement is automatically calculated by the equipment, which reduces the human participation in the measurement process and improves the measurement efficiency and measurement accuracy.

[0024] Example 2:

[0025] like Figure 1-Figure 7 As shown, the base 1 of the present invention serves as the basic structure. A support plate 2 is fixedly mounted on the base 1. The stability and rigidity of the support plate 2 ensure the overall performance of the equipment. A slide rail 3 and a first cylinder 4 are mounted on the support plate 2. The slide rail 3 supports the movement of the push seat 5 while ensuring that other components are installed in a straight line, reducing errors during measurement. The push seat 5, movably mounted on the slide rail 3, can move linearly under the guidance of the slide rail 3, ensuring accurate contact with the motor being measured during measurement.

[0026] The first cylinder 4 drives the push seat 5. After the motor to be tested is placed in the motor seat 9, the test process is started. The first cylinder 4 pushes the push seat 5 to move linearly, so that the top seat 6 on the push seat 5 abuts the motor to be tested. The push seat 5 and the top seat 6 are connected in an active manner, and the push seat 5 and the top seat 6 are directly provided with a spring 17. After the top seat 6 abuts the motor to be tested, the push seat 5 continues to push, so that the spring 17 is compressed, which plays an elastic buffering role, so that the top seat 6 elastically abuts the motor to be tested, plays a role in protecting the motor, and at the same time ensures that the top seat 6 is firmly abutted on the motor to be tested, and cooperates with the motor seat 9 to fix the motor to be tested, ensuring that the motor will not be displaced by external vibration or impact during the test, thereby affecting the measurement results. The activity of the push seat 5 and the cooperation of the first cylinder 4 enable the operator to achieve the compression and fixation of the top seat 6 without manual intervention. This improvement significantly improves the efficiency and accuracy of the measurement.

[0027] After the motor to be tested is fixed under the elastic pressure of the push seat 6, the measuring cylinder 7 fixed on the push seat 5 is activated. The measuring cylinder 7 drives the ejector pin 8 forward through air pressure, so that the front end of the ejector pin 8 contacts the shaft core of the motor to be tested, and the motor virtual position is measured.

[0028] The motor base 9 and the support 10 are also fixedly mounted on the carrier plate 2. The measuring gauge 11 installed on the support 10 will be used for actual virtual position measurement. During the measurement process, the shaft core of the motor to be tested is pushed by the ejector pin 8 to contact the measuring rod of the measuring gauge 11. The measuring gauge 11 can quickly respond to the slight displacement changes of the shaft core and provide real-time feedback of the measurement results, including digital tube display. The measuring gauge 11 is connected to the controller via a data cable, and the controller analyzes and processes the received data. The processed data will be directly transmitted to the display screen 22, making it convenient for the operator to observe and record the measurement results in real time. This automated process reduces the steps of manual operation, greatly improves the efficiency of measurement, and reduces the impact of human factors on the results.

[0029] During the entire measurement process, the operator simply places the motor into the motor holder 9 and presses the start button. The device automatically completes the motor's virtual position measurement, increasing measurement speed, reducing human error, and improving the reliability of the measurement results. Furthermore, the highly automated measurement process reduces operator workload, thereby improving work efficiency.

[0030] A clamping cylinder 12 is fixedly mounted on the support plate 2 of the present invention, and the clamping cylinder 12 drives the connection clamping block 13. This structure further improves the stability of the motor to be tested during the test process, ensuring that the motor will not undergo any displacement during the entire measurement process, thereby effectively reducing the measurement error caused by the displacement of the motor. After the motor to be tested is placed in the motor seat 9, the clamping cylinder 12 will be started, and then the clamping block 13 will begin to move downward to clamp the motor to be tested. The movement of the clamping block 13 is driven by the air pressure of the clamping cylinder 12, so that the clamping block 13 can apply uniform and stable pressure, ensuring that the motor to be tested is always in a stable state during the measurement process. At this time, the clamping block 13 firmly fixes the motor to be tested on the motor seat 9, thereby preventing any external interference or vibration during the measurement process from causing the displacement of the motor. The automation of this process not only improves the measurement efficiency, but also ensures the accuracy of the measurement. During the startup of the clamping cylinder 12, the gas inside the cylinder is introduced through the pipeline system, pushing the piston to move downward. The downward movement of the piston drives the compression block 13 connected below it toward the motor under test, generating a strong downward pressure. This downward pressure ensures good contact between all contact surfaces of the motor under test and the motor base 9, thereby reducing measurement errors caused by poor contact. Furthermore, the adjustable air pressure of the compression cylinder 12 allows the operator to flexibly adjust the pressure applied by the compression block 13 according to the different motor types under test or measurement requirements. This adjustability ensures stable performance across a wide range of motor types.

[0031] The motor base 9 of the present invention is fixedly mounted with a baffle 14, which is provided with a U-shaped groove 15. After the motor to be tested is placed in the motor base 9, the top base 6 will apply downward pressure to fix the motor to be tested on the motor base 9. During this process, the presence of the baffle 14 plays a crucial role in limiting the movement of the motor to be tested. When the motor to be tested is placed in the motor base 9, it will first slide into the inside of the U-shaped groove 15. The shape of the U-shaped groove 15 is larger than the axis diameter of the motor to be tested, providing a groove to accommodate the motor, allowing the motor base 9 to be placed inside. When the top base 6 applies pressure, the top base 6 will come into close contact with the motor to be tested and, through the restriction of the baffle 14, further prevent the motor from moving during the test. The baffle 14 physically blocks the motor to be tested from shifting laterally or vertically within the motor base 9. In this way, the axis of the motor to be tested always remains at the center of the U-shaped groove 15, providing a stable measurement basis. This design ensures that during the measurement process, the various components of the motor are not affected by external factors and their positions are not changed, thereby obtaining more accurate measurement results.

[0032] The top seat 6 of the present invention is provided with an assembly hole 16, which elastically abuts the push seat 5 via a spring 17. During the test process, after the top seat 6 abuts the motor to be tested, the push seat 5 continues to push, and the spring 17 is subsequently compressed, forming an elastic buffer mechanism. This elastic buffering effect helps the top seat 6 elastically abut the motor to be tested, ensuring that the motor itself is protected from damage during the measurement process, while also maintaining the top seat 6 firmly abutting the motor to be tested. When the device is operating, the top seat 6 first contacts the motor to be tested under the action of the clamping cylinder 12. At this time, the push seat 5 continues to move downward through the drive connection, compressing the spring 17 in the assembly hole 16. The compression of the spring 17 allows the top seat 6 to move slightly within a certain range, thereby preventing damage to the motor due to sudden contact force. This design ensures that while the top seat 6 applies pressure, the motor to be tested can be contacted in a more gentle manner, reducing the possibility of impact or damage. The combination of the assembly hole 16 and the spring 17 makes the contact between the top seat 6 and the motor to be tested more flexible. The presence of spring 17 not only provides elasticity between the top seat 6 and the motor, but also absorbs tiny vibrations during the measurement process. This is especially important for motor virtual position measurement, because any tiny external interference or error may lead to inaccurate measurement results. Through such a design, the stability of the motor to be tested during measurement is enhanced, and the accuracy of the measurement data is further guaranteed. When the push seat 5 continues to push and the spring 17 is compressed to a certain extent, the top seat 6 will always maintain good contact with the motor to be tested under the reaction force of the spring 17. During the contact process between the top seat 6 and the motor to be tested, the spring 17 also plays a role in preventing the top seat 6 from applying excessive pressure. This protective mechanism allows the top seat 6 to effectively avoid excessive pressure on the motor when it contacts the motor to be tested, protecting the sensitive components of the motor from damage. In this way, the spring 17 not only ensures a stable contact between the top seat 6 and the motor, but also provides additional protection for the safety of the equipment.

[0033] A second cylinder 18 is fixedly mounted on the support plate 2 of the present invention, and the second cylinder 18 is connected to the adjustment seat 19 through a drive connection. The design of the adjustment seat 19 includes a limit block, and the installation position of the limit block is adjacent to the measuring table 11. The function of the measuring table 11 is to monitor the position of the shaft core of the motor to be tested during the measurement process and obtain relevant data through the measuring rod of the measuring table 11. The ejector pin 8 contacts the shaft core of the motor to be tested through the adjustment seat 19, so that the other end of the shaft core acts on the measuring rod of the measuring table 11 to complete the displacement measurement, and thus feedback the data to the device to automatically calculate the virtual position. During the measurement process, the function of the ejector pin 8 is to apply an axial force to the shaft core of the motor to be tested, so that the measuring table 11 measures the virtual position of the motor. However, there is a risk that the ejector pin 8 may directly push the shaft core out of the interior of the motor to be tested in the process of pushing the shaft core. If this situation is not controlled, the measuring rod of the measuring table 11 will be pushed too far, thereby damaging the measuring table 11. To address this potential problem, the design of the adjustment base 19 and the stop block is crucial. Adjusting the adjustment base 19 conveniently changes the relative position of the stop block and the measuring gauge 11. This ensures that the stop block contacts the measuring gauge 11 just as the ejector pin 8 pushes the shaft core outward a certain distance, preventing further damage to the measuring rod.

[0034] A control box 21 is fixedly mounted on the base 1 of the present invention, and a display screen 22 and control buttons 23 are installed on the control box 21. The display screen 22 is used to display the measurement results and equipment status in real time. The operator can intuitively observe the virtual position measurement results of the motor to be tested through the display screen 22. The design of the display screen 22 takes into account readability and information volume, ensuring that the operator can clearly obtain key information in different working environments. At the same time, the display screen 22 can also display the working status of the equipment, fault information and other necessary prompt information, so as to promptly discover and deal with potential problems. The control buttons 23 facilitate the operator to perform operations such as starting, stopping and setting parameters of the equipment. The design of the buttons follows ergonomic principles to ensure that operations can be performed conveniently and quickly in different situations. The operator only needs to press the corresponding control button 23 to easily control the measurement process. Through the control button 23, the operator can choose to start the measurement, stop the measurement, or adjust the relevant parameters of the measurement to meet the measurement needs of different types of motors. The control chassis 21 also houses a power switch and an emergency stop button. The power switch controls the overall power supply to the device, while the emergency stop button quickly cuts off power in an emergency, ensuring safe operation. Through this series of control functions, the control chassis 21 provides a reliable operating platform for the entire motor virtual position measurement device. During motor virtual position measurement, the control chassis 21 is tightly connected to the rest of the device, ensuring real-time data transmission. After measurement data is collected by the control system, it is updated in real time on the display screen 22. This allows operators to view the latest data at any time during the measurement process, facilitating recording and analysis of measurement results.

[0035] The limit block 20 may also be equipped with a spring of different strengths, and the spring force acts directly on the measuring needle of the measuring meter to increase the measuring force of the measuring meter.

[0036] 1) The internal resistance to movement of the rotor shaft core of different motors is different, and different customers require different force measurements. However, the spring force of the measuring meter is a certain value, and there is a phenomenon that the force value is small and the motor rotor shaft core cannot be pushed.

[0037] 2) Controllable force measurement means that the force of the measuring cylinder 7 pushing the ejector pin 8 is variable and controllable, and the force of the measuring gauge + spring is also variable and controllable.
