Preferably, the first rotating shaft arm and the second rotating shaft arm can be used as workpieces which are connected with a screen and a machine body of the notebook computer to drive the rotating shafts to rotate to control the opening and closing angles of the notebook computer.

Step 103, acquiring a first torque parameter of the first test object driven by the test device.

In the embodiment of the application, the fastener in the first test object is rotated by using the adjusting device, preferably, the adjusting device can be a floating lock head connected with the servo motor, the servo motor is controlled by the PLC control system to rotate forwards or reversely by a certain angle so as to realize the rotation of the fastener, and in the embodiment, the fastener is a fixing nut.

In the embodiment of the application, the rotating shaft torque is generated by the rotating friction among the rotating shaft assembly, namely the rotating shaft, the first rotating shaft arm and the friction plate in the first assembly and the second assembly, and the elastic sheet is used for providing the pressure required by friction generation. Preferably, there are a plurality of friction plates, and two friction plates are used in this embodiment. Simplifying the two friction plates into two friction disks, R being the outside diameter, R ₀ Is the inner diameter, and F is the pressure born by the friction surface;

step 201, feeding and collecting images. In the method for automatically adjusting the torque of the rotating shaft according to the embodiment, a loading operation is required at the beginning, and preferably, an automatic loading device is used for clamping the assembled rotating shaft on a turntable station at a predetermined position, and correspondingly fixing the torque testing mechanism, the mechanical adjusting mechanism and the rotating shaft.

Preferably, the torque testing mechanism and the mechanical adjusting mechanism are respectively matched with two ends of the rotating shaft, so that the torque can be directly adjusted without transmitting a rotating shaft workpiece to the adjusting mechanism after the torque of the rotating shaft is tested.

In the embodiment of the application, the image acquisition device is adopted to acquire and identify the image of the clamped rotating shaft, the identification result is sent to the processor, and the processor responds to the identification result to call a preset algorithm program.

Step 202, testing the torque of the rotating shaft. The torque of the rotating shaft is tested by the torque testing mechanism, preferably, the torque testing mechanism adopts a servo motor to drive the torque sensor, the torque sensor is connected with a shifting fork, the shifting fork shifts a rotating shaft arm to rotate, the rotating shaft torque value is automatically tested during rotation, and the rotating shaft torque value is output by the torque sensor in real time.

And step 203, comparing whether the torque of the rotating shaft obtained by the test meets the specification torque. In this embodiment, preferably, the PLC processor receives data output by the torque sensor, compares a measured torque value with a specification torque, and determines that the rotating shaft workpiece is qualified if the measured torque value is within the specification torque range after the comparison; if the torque is not within the specification torque range after the comparison, the spindle workpiece is determined to be unqualified, and step 204 is executed.

And step 204, adjusting the rotating shaft according to the test result. In this embodiment, since the specification parameters of each component are determined after the design of the rotating shaft is finished, when the difference between the torque of the rotating shaft and the specification torque is measured, the angle at which the fastening nut needs to rotate can be directly obtained according to a preset program algorithm, and therefore the system controls and guides the lock nut mechanism to rotate forwards or backwards and how many angles the fastening nut needs to rotate, and the torque of the rotating shaft is adjusted to be within the specification through a specific algorithm.

Step 205, retest the torque of the rotating shaft.

In the embodiment of the present application, the torque of the rotating shaft adjusted in step 204 is retested to obtain an adjusted torque test result. The retested rotating shaft torque is also used for correcting the X value, and the retested rotating shaft torque specifically comprises the following steps: and recalculating the X value according to the retest result and the rotation angle of the fixing nut obtained by calculation, and revising the initial X value by collecting a certain number of X values.

Preferably, since the processing flow and the specification and size of the part are less affected by the outside, the value X is corrected by setting a processing time, for example: after the rotating shaft is adjusted for 1h, collecting the retest value of the rotating shaft adjusted within 1h, re-calculating the X value corresponding to each rotating shaft within 1h according to the operation relation among the X value, the retest value and the rotating angle in the algorithm, calculating an average value, and using the calculated average value for the X value of the next time period; or by setting a machining number to correct the X value, for example: after each 100 rotating shaft adjustments are completed, the retest torques of the 100 rotating shafts after the adjustments are completed are collected, the X values corresponding to the 100 rotating shafts are re-solved according to the operation relation among the X values, the retest values and the rotating angles in the algorithm, the average value is calculated, and the calculated average value is used as the X value in the subsequent 100 rotating shaft adjustments.

And step 206, comparing whether the torque of the rotating shaft obtained by retesting meets the specification torque.

In the embodiment of the application, the torque value obtained by retesting is compared with the specification torque value to ensure that the final rotating shaft is within the specification. If yes, the torque automatic adjustment process is ended as a qualified product, and if not, step 207 is performed.

And step 207, adjusting the torque of the rotating shaft according to the retest result.

In this embodiment, when the retest result does not satisfy the specification torque, the difference between the retest result and the specification torque is determined to replace the difference between the torque of the rotating shaft and the specification torque in step 204, and the algorithm program in step 204 is executed to adjust the rotating shaft, so as to ensure that the final torque meets the specification torque.
