[0002] In actual production, parts usually need to be torque measured at multiple positions. Currently, the torque measurement process relies on manual operation. Usually, a positioning jig needs to be installed on a mechanical torque wrench, and then the part to be measured is placed on the positioning jig. Before measurement, the mechanical torque wrench is zeroed, and then the employee slowly rotates the part forward and backward by hand. Each measurement depends on the stability and uniformity of the employee's technique. The above method has low measurement efficiency and it is difficult to ensure the stability of the rotation force during the measurement process, resulting in errors in the measurement results.
[0003] In addition, for better traceability when a product has an abnormality, it is also necessary for the employee to input the measured forward and backward torque values into the computer, which not only increases the operation steps, but also easily causes data errors or omissions due to human factors, further affecting the accuracy of the measurement data.

[0055] Embodiments of this application provide an automatic torque measurement system, including an automatic torque measurement fixture and a terminal. Among them, with reference to Figure 1 , the automatic torque measurement fixture includes a slide table assembly 100, a motor 200, a transmission device 300, a clamping device 400, a component positioning fixture 500, a digital display torque wrench 600, and a circuit controller.
[0056] The terminal is connected to the circuit controller, and the circuit controller is used to receive the test position information sent by the terminal.
[0057] The circuit controller is respectively connected to the slide table assembly, the clamping device, and the motor. The circuit controller is used to control the telescopic movement of the slide table assembly according to the test position information so that the clamping device moves to the component test position, and to control the rotation of the motor.
[0058] The motor is arranged on the slide table assembly and is connected to the clamping device through the transmission device. The motor is used to drive the component to rotate.
[0059] The digital display torque wrench is connected to the component positioning fixture, and the digital display torque wrench is used to measure the torque value of the component rotation.
[0060] The terminal is connected to the digital display torque wrench, and the terminal is used to receive the torque value sent by the digital display torque wrench.
[0061] In this embodiment, the automatic torque measurement system includes an automatic torque measurement fixture and a terminal. The automatic torque measurement fixture includes a slide table assembly, a motor, a transmission device, a clamping device, a component positioning fixture, a digital display torque wrench, and a circuit controller.
[0062] It can be understood that the terminal can be a smart phone, a tablet computer, a notebook computer, a desktop computer, etc., but is not limited thereto.
[0063] Specifically, the staff sends the test position information through the terminal and places the component to be tested in the component positioning fixture. The terminal is connected to the circuit controller through a data cable. After receiving the test position information sent by the terminal, the circuit controller automatically controls the telescopic movement of the slide table assembly according to the received test position information so that the clamping device moves between multiple component measurement positions, and controls the rotation of the motor each time the clamping device moves to a component test position.
[0064] Exemplarily, as Figure 2As shown, the two component test positions are the first measurement position T1 and the second measurement position T2 respectively, where T2 is higher than T1. In the order of the component test positions from low to high, first control the slide table assembly to contract from the fully extended state until the clamping device just moves to T1, and then drive the component to rotate by the rotation of the motor, and measure the torque value at T1 through the digital display torque wrench.
[0065] After measuring the torque value at T1, the circuit controller controls the slide table assembly to extend until the clamping device just moves to T2, and then drives the component to rotate by the rotation of the motor, and measures the torque value at T2 through the digital display torque wrench.
[0066] After measuring the torque value at T2, the circuit controller controls the slide table assembly to extend fully, so that the staff can take out the currently tested component and put in a new component to be tested.
[0067] During the torque test, each time the digital display torque wrench measures the torque value, it is sent to the terminal through the data line for data recording.
[0068] Refer to Figure 1 , in the embodiment of the present application, the automatic torque measuring jig further includes a bottom plate 701 and a shock pad 702.
[0069] The first surface of the bottom plate is connected to the slide table assembly and the digital display torque wrench.
[0070] The second surface of the bottom plate is connected to the shock pad, where the second surface is the surface of the bottom plate opposite to the first surface.
[0071] In this embodiment, the upward horizontal surface of the bottom plate is the first surface, and the first surface is connected to the slide table assembly and the digital display torque wrench. The bottom plate, as a rigid structure, provides a stable installation platform for the slide table assembly and the digital display torque wrench, can effectively support these components, prevent the automatic torque measuring jig from displacing or vibrating during the measurement process, and improve the stability and reliability of the measurement.
[0072] The second surface of the bottom plate is the surface of the bottom plate opposite to the first surface, that is, the bottom of the bottom plate is the second surface, and the second surface is connected to the shock pad. The external vibration is absorbed and isolated through the shock pad. As Figure 1 shown, shock pads can be set at the four top corner positions of the second surface of the bottom plate.
[0073] Refer to Figure 1 , in the embodiment of the present application, the clamping device includes a rotating shaft 401, an open clamp cylinder 402, a connecting piece 403 and a claw 404.
[0074] The open clamp cylinder is connected to the transmission device through the rotating shaft.
[0075] The claw is connected to the open clamp cylinder through the connecting piece.
[0076] In this embodiment, the clamping device includes a rotating shaft, an open clamp cylinder, a connecting member, and a claw. The rotating shaft is fixedly connected to the open clamp cylinder and is connected to the transmission device through the rotating shaft. The claw is installed on the open clamp cylinder through the connecting member and is used to hold the component.
[0077] During the process of measuring the torque, the motor rotates to drive the transmission device to rotate, causing the rotating shaft to rotate. Since the rotating shaft and the open clamp cylinder are fixed together, the open clamp cylinder rotates together with the rotating shaft, resulting in the claw driving the measurement position of the component to rotate.
[0078] Refer to Figure 1 , in the embodiment of the present application, the sliding table assembly includes a first sliding table unit and a second sliding table unit. Among them, the first sliding table unit includes a first pad 101, a first sliding table cylinder 102, and a connecting block 103, and the second sliding table unit includes a second backing plate 104, a second sliding table cylinder 105, and a connecting plate 106.

[0088] Specifically, the first synchronous pulley and the second synchronous pulley are connected by belt drive. Among them, the first synchronous pulley is connected to the clamping device, and the second synchronous pulley is connected to the motor. When the motor rotates, the second synchronous pulley rotates following the motor. The second synchronous pulley drives the first synchronous pulley to rotate through the synchronous belt, so that the clamping device rotates, thereby driving the part to rotate and realizing torque measurement.

The auxiliary fixing plate and the movable adjusting block are connected by bolts to fix the digital display torque meter on the first surface of the bottom plate through the third backing plate.
[0093] Furthermore, a connection plate is provided on the digital display torque meter. The digital display torque meter is connected to the part positioning fixture through the connection plate to measure the torque value according to the rotation of the part to be tested in the part positioning fixture.
[0094] In the embodiment of the present application, the test position information includes a first preset position, a second preset position, and a third preset position. Refer to Figure 2 , the part test positions include a first measurement position and a second measurement position. Refer to Figure 3 , the first sliding table cylinder is provided with a first magnetic switch assembly 800. The first magnetic switch assembly includes a first magnetic switch sensor 801 and a second magnetic switch sensor 802. Among them, the first magnetic switch sensor is located at the bottom of the first sliding table cylinder, and the second magnetic switch sensor is located at the top of the first sliding table cylinder; the first magnetic switch sensor is used to output a first induction signal when the first sliding table cylinder retracts to the first preset position; the second magnetic switch sensor is used to output a second induction signal when the first sliding table cylinder fully extends.
[0095] The second sliding table cylinder is provided with a second magnetic switch assembly 900. The second magnetic switch assembly includes a third magnetic switch sensor 901 and a fourth magnetic switch sensor 902. Among them, the third magnetic switch sensor is located at the bottom of the second sliding table cylinder, and the fourth magnetic switch sensor is located at the top of the second sliding table cylinder. The third magnetic switch sensor is used to output a third induction signal when the second sliding table cylinder retracts to the second preset position. The fourth magnetic switch sensor is used to output a fourth induction signal when the second sliding table cylinder extends to the third preset position. The fourth magnetic switch sensor is also used to output a fifth induction signal when the second sliding table cylinder fully extends.
[0096] The opening clamp cylinder is provided with a fifth magnetic switch sensor. The fifth magnetic switch sensor is used to output a first transposition signal when the opening clamp cylinder opens from the first measurement position. The fifth magnetic switch sensor is also used to output a second transposition signal when the opening clamp cylinder opens from the second measurement position.
[0097] In this embodiment, the test position information includes a first preset position, a second preset position, and a third preset position. Among them, the first preset position is the target position where the first sliding table cylinder retracts, the second preset position is the target position where the second sliding table cylinder retracts, and the third preset position is the target position where the second sliding table cylinder extends.
[0098] The first sliding table cylinder is provided with a first magnetic switch assembly. The first magnetic switch assembly includes a first magnetic switch sensor and a second magnetic switch sensor. The first magnetic switch sensor is located at the bottom of the first sliding table cylinder, and the second magnetic switch sensor is located at the top of the first sliding table cylinder.
[0099] The second sliding table cylinder is provided with a second magnetic switch assembly. The second magnetic switch assembly includes a third magnetic switch sensor and a fourth magnetic switch sensor. Among them, the third magnetic switch sensor is located at the bottom of the second sliding table cylinder, and the fourth magnetic switch sensor is located at the top of the second sliding table cylinder.
[0100] The first magnetic switch sensor is used to output a first induction signal when the first sliding table cylinder retracts to the first preset position. The first induction signal indicates that the first sliding table cylinder has moved to the target position of retraction. The third magnetic switch sensor is used to output a third induction signal when the second sliding table cylinder retracts to the second preset position. The third induction signal indicates that the second sliding table cylinder has moved to the target position of retraction.
[0101] When the first magnetic switch sensor outputs the first induction signal and the third magnetic switch sensor outputs the third induction signal, it means that the sliding table assembly has reached the first measurement position of the component by simultaneously retracting the first sliding table cylinder and the second sliding table cylinder, and the torque test can be started at the first measurement position.
[0102] A fifth magnetic switch sensor is provided on the open clamp cylinder. When the torque test at the first measurement position of the part is completed and the part rotates back to the test origin, the open clamp cylinder will automatically open. The fifth magnetic switch sensor on the open clamp cylinder is used to output a first transposition signal when the open clamp cylinder opens from the first measurement position. The first transposition signal indicates that the first measurement position of the part has been tested and the state of the slide table assembly needs to be adjusted to change the measurement position.
[0103] Specifically, as Figure 2 shown, the second measurement position is above the first measurement position. Therefore, in this embodiment, the measurement position is adjusted by extending the second slide cylinder. The fourth magnetic switch sensor is used to output a fourth induction signal when the second slide cylinder extends to the third preset position. The fourth induction signal indicates that the second slide cylinder has moved to the extended target position.
[0104] When the fourth magnetic switch sensor outputs the fourth induction signal, it means that the slide table assembly has reached the second measurement position of the part by extending the second slide cylinder, and the torque test at the second measurement position can be started.
[0105] When the torque test at the second measurement position of the part is completed and the part rotates back to the test origin, the open clamp cylinder will automatically open. The fifth magnetic switch sensor on the open clamp cylinder is used to output a second transposition signal when the open clamp cylinder opens from the second measurement position. The second transposition signal indicates that the second measurement position of the part has been tested and the state of the slide table assembly can be adjusted to facilitate the removal of the part.
[0106] The second magnetic switch sensor is used to output a second induction signal when the first slide cylinder is fully extended. The second induction signal indicates that the first slide cylinder has been fully extended.
[0107] The fourth magnetic switch sensor is also used to output a fifth induction signal when the second slide cylinder is fully extended. The fifth induction signal indicates that the second slide cylinder has been fully extended.
[0108] When the second magnetic switch sensor outputs the second induction signal and the fourth magnetic switch sensor outputs the fifth induction signal, it means that the slide table assembly has been fully extended, and the measurements at multiple measurement positions of the current part have been completed. The current part can be removed and the next part to be tested can be replaced.
[0109] In the embodiment of the present application, the circuit controller is respectively connected to the first magnetic switch assembly, the second magnetic switch assembly, and the fifth magnetic switch sensor.
[0110] The circuit controller is used to control the opening clamp cylinder to retract at the first measuring position and control the motor to rotate when receiving the first induction signal and the second induction signal; control the second slide cylinder to extend to the third preset position when receiving the first transposition signal; control the opening clamp cylinder to retract at the second measuring position and control the motor to rotate when receiving the fourth induction signal; control the first slide cylinder and the second slide cylinder to fully extend when receiving the second transposition signal; and control the slide assembly to enter a standby state when receiving the third induction signal and the fifth induction signal.
[0111] In this embodiment, the circuit controller is connected to the first magnetic switch assembly, the second magnetic switch assembly and the fifth magnetic switch sensor respectively. The circuit controller receives the signals output by each magnetic switch sensor and controls the opening clamp cylinder, the motor, the first slide cylinder and the second slide cylinder according to the signals.
[0112] Specifically, when the circuit controller receives the first induction signal and the second induction signal, the circuit controller controls the open clamp cylinder to contract so that the claws clamp the first measuring position of the part. After the claws clamp, the circuit controller drives the motor to start rotating to detect the torque value at the first measuring position.
[0113] When the circuit controller receives the first position change signal, the circuit controller controls the second slide cylinder to extend from the second preset position to the third preset position to switch the component measurement position.
[0114] When the circuit controller receives the fourth sensing signal, the circuit controller controls the open clamp cylinder to contract so that the claws clamp the second measuring position of the component. After the claws clamp, the circuit controller drives the motor to start rotating to detect the torque value at the second measuring position.
[0115] When the circuit controller receives the second position change signal, the circuit controller controls the first slide cylinder to fully extend from the first preset position, and controls the second slide cylinder to fully extend from the third preset position, so as to take out the component currently being tested.
[0116] When the circuit controller receives the third sensing signal and the fifth sensing signal, it controls the slide assembly to enter a standby state, waiting for the employee to put in the next test component.
[0117] In an embodiment of the present application, the terminal includes a data processing module, a storage module and a display module.
[0118] The data processing module is used to determine the range of the received torque value and obtain the measurement result.
[0119] The storage module is used to store torque values and measurement results.
[0120] The display module is used to display the torque value and measurement results.
[0121] Specifically, the terminal includes a data processing module, a storage module, and a display module. The data processing module is used to determine the range of the received torque value according to a preset threshold range. If the torque value is within the threshold range, the measurement result is obtained as passed, indicating that the currently measured torque value data is normal. If the torque value is not within the threshold range, for example, the torque value is less than the lower limit of the threshold or the torque value is greater than the upper limit of the threshold, the measurement result is obtained as failed, indicating that the currently measured torque value data is abnormal.
[0122] The storage module stores the measured torque value and the corresponding measurement result for tracing the defective parts.
[0123] The display module displays the measured torque value and the corresponding measurement result. For example, the measured torque value and the measurement result are displayed through a display screen.
[0124] It should be noted that in addition to the display screen, the display module can also be a touch screen. The operator can directly view the measurement result through the touch screen and set parameters for human-machine interaction.
[0125] Figure 4 is an optional flowchart of the automatic torque measurement method provided by the embodiment of the present application. Figure 4 The method in may include but is not limited to steps S101 to S105.

[0127] Step S102, control the telescopic movement of the slide table assembly according to the test position information through the circuit controller to move the clamping device to the part test position, and control the rotation of the motor.
[0128] Step S103, drive the part to rotate through the motor.
[0129] Step S104, measure the torque value of the rotating part through a digital display torque meter.
[0130] Step S105, receive the torque value sent by the digital display torque meter through the terminal.
[0131] Next, in combination with specific application examples, the solution of the embodiment of the present invention will be introduced and described in detail.
[0132] The automatic torque measurement system provided by the embodiment of the present application uses a computer as the terminal, and a dedicated test software system is deployed in the computer. Refer to Figure 1, the automatic torque measuring fixture includes a first backing plate 101, a first slide table cylinder 102, a connecting block 103, a second backing plate 104, a second slide table cylinder 105, a connecting plate 106, a stepping motor, a first synchronous pulley 301, a synchronous belt 302, a second synchronous pulley 303, a rotating shaft 401, an opening clamp cylinder 402, a connecting member 403, V-shaped claws, a part positioning fixture 500, a digital display torque wrench 600, a third backing plate 601, a connecting disc 602, an auxiliary fixing plate 603, a movable adjusting block 604, a bottom plate 701, a shock pad 702 and a circuit controller.
[0133] The operation method is as follows: Before the measurement starts, turn on the power of the circuit controller and the air pressure ventilation switch to fully extend the first slide table cylinder and the second slide table cylinder. Then turn on the power of the digital display torque wrench, connect the digital display torque wrench to the computer through a data cable, and run the dedicated test software system on the computer.
[0134] Refer to Figure 5 , in the test software system, set information such as the connection serial port number, storage file path, baud rate, etc. through the system settings interface, and then further edit relevant parameters such as the product model, upper and lower limits of the torque at the part measurement position of the product through the test template editing interface.
[0135] It should be noted that lenses of different product models may have different torque test requirements, such as part measurement positions and upper and lower limits of torque. To facilitate adapting to differences between different products, templates for different product models can be preset in the test template. When measuring products of different models, just select the corresponding test template in the test template editing interface, and the software will automatically call the preset template for parameter configuration. For example Figure 6 As shown, when the product model is 4BAP 4100, the upper and lower limit values of the first measurement position and the upper and lower limit values of the second measurement position can be set through the TEST4 template.
[0136] It can be understood that if there is no product model in the test template that matches the current test part, a new test template can also be added in the test template editing interface, and subsequent operations can be performed after inputting the required parameters.
[0137] After setting the parameters through the test template editing interface, rotate the two parts of the part to be measured for torque to the starting point, then place them in the part positioning fixture, press the start switch. When the first slide table cylinder and the second slide table cylinder simultaneously retract to their set positions, the magnetic switch sensors at the bottoms of the first slide table cylinder and the second slide table cylinder simultaneously output signals, causing the opening clamp cylinder to retract and clamp, so that the V-shaped claws hold the first measurement position of the part tightly. After the claws hold tightly, the stepping motor starts to rotate positively in the counterclockwise direction.
[0138] It can be understood that the rotation of the motor drives the first synchronous pulley through the second synchronous pulley and the synchronous belt, causing the opening clamp cylinder connected to the rotating shaft to rotate. Since the opening clamp cylinder is fixed to the rotating shaft, the opening clamp cylinder rotates together with the rotating shaft. The V-shaped claw is installed on the opening clamp cylinder through a connecting piece, resulting in the rotation of the first measurement position of the driven part.
[0139] When the stepping motor rotates forward to a certain angle (the rotation angle is controlled by the circuit controller), it pauses (the pause time is set) for a while and then automatically rotates counterclockwise back to the origin, and then the opening clamp cylinder automatically opens.
[0140] When the opening clamp cylinder opens, the magnetic switch sensor on the opening clamp cylinder outputs a signal, causing the second sliding table cylinder to extend. When the second sliding table cylinder extends to the set position, the magnetic switch sensor on the top of the second sliding table cylinder outputs a signal, causing the opening clamp cylinder to retract and the V-shaped claw to hold the second measurement position of the part tightly. Then the stepping motor starts to rotate forward again to drive the second measurement position of the part to rotate. After the stepping motor rotates forward to a certain angle, it pauses for a while and then rotates backward back to the origin. Similar to the first measurement position of the measured part, after returning to the origin, the opening clamp cylinder opens, and the magnetic switch sensor on the opening clamp cylinder outputs a signal, causing the first sliding table cylinder and the second sliding table cylinder to extend completely, ending the measurement process.
[0141] During the measurement process, the dedicated test software system on the computer will record according to the torque value measured by the digital display torque wrench, automatically record the measurement date, time, and the forward and reverse measurement torque values at the two positions into a table, and make a judgment by comparing with the preset upper and lower torque limits. If the measured value is within the set upper and lower limits, the measurement result is confirmed as OK; otherwise, the measurement result is NG, as Figure 7 shown.
[0142] When all the parts to be measured have been measured, the employee can click the save button to save the table to the set storage path.
[0143] The automatic torque measurement system provided by the embodiment of the present application is easy to operate, can automatically measure the torque of two parts of the lens, improves the measurement efficiency. Even if the distances between the two measurement parts of different models of lenses are different, it can automatically adjust the measurement distance according to the product model, and the measurement rotation angle is adjustable. At the same time, the automatic import of data by the dedicated software avoids the error phenomenon caused by manual input, and real-time displays the measurement result OK or NG, featuring stable rotation during the measurement process and accurate measurement results.
