In the second embodiment, the operator can be skilled in distinguishing the angle of the seat ring, and can also know the standard angle (angle after calibration and repair) of the conical surface 701 on the selected processing module 7 and obtain the thickness of the current processing module 7 by using a vernier caliper, but the actual angle (angle before calibration and repair) of the conical surface 701 on the processing module 7 to be calibrated and repaired is not determined, so the angle detection module 9 is designed in this embodiment. Before the angle detection, the thickness value of the current processing module 7 is measured. If the thickness value is smaller than or equal to the minimum scrapped thickness value, the processing module 7 is judged to be unqualified and not to be repaired, if the thickness value is qualified, the angle detection is carried out on the processing module 7, after the angle detection module 9 detects that the angle of the selected conical surface 701 is very accurate, the processing module can be directly used without using the adjusting device, and if the angle error of the grinding wheel is detected, the processing module 7 is required to be repaired through the adjusting device and then used.

Further, referring to fig. 10, since the spline rod end of the machining module 7 is different in length and the selected support column 503 adapted to the machining module 7 is also different in length, when the machining module 7 is automatically pressed by the driving cylinder 307, the case 305 will have an excessive pressing force when pressing the machining module 7 after moving down, which is easy to cause excessive friction between the conical surface 701 of the machining module 7 and the polishing head 607 if the pressing force is excessive, to increase wear and even damage the conical surface, and to cause loosening or deflection of the machining module 7 in the rotational polishing process if the pressing force is too small, resulting in uneven repairing surface and reduced accuracy. Therefore, in the automatic processing process, it is difficult to quickly and accurately adjust and maintain proper pressing force, and repair quality and efficiency are affected.
Referring to fig. 2, a connection seat 303 is provided between the output end of the cylinder 307 and the cross plate surface of the support plate 301, the connection seat 303 is used for connecting the cylinder 307 and the support plate 301, and the detection unit further includes a component for detecting and adjusting pressure provided on the connection seat 303.

Referring to fig. 10, the connection seat 303 includes an upper slider 3031, a lower slider 3032, a first spring 3033, an adjustment screw 3034, and a guide post 3035. The upper carriage 3031 is fixedly connected with the output end of the air cylinder 307, the lower carriage 3032 is fixedly connected with the transverse plate surface of the support plate 301, and the upper carriage 3031 is slidably connected with the lower carriage 3032 through at least two guide posts 3035. Then, the first spring 3033 is sleeved between the protrusions of the upper slider 3031 and the lower slider 3032. The adjusting screw 3034 is screwed to the transverse plate surface of the support plate 301 and is rotatably connected to the bottom of the lower slide 3032, and the initial distance between the upper slide 3031 and the lower slide 3032 can be changed by screwing the adjusting screw 3034, so that the preload of the first spring 3033 is adjusted.
The components on the connection seat 303 for detecting and adjusting pressure include a pressure detection ring 3036 and a displacement sensor 3037. An annular groove is formed in the lower slide 3032 at the top plane of the protrusion thereof, and the pressure detection ring 3036 is embedded in the annular groove. The pressure detection ring 3036 is preferably a thin film pressure sensor or a strain gauge force ring with its detection end face flush with or slightly convex to the bottom surface of the annular groove. The lower end of the first spring 3033 abuts against the detection end surface of the pressure detection ring 3036, so that the pressure transmitted by the first spring 3033 can be accurately detected in real time. The displacement sensor 3037 is embedded and mounted on the upper carriage 3031, and its detection direction is parallel to the guide post 3035, for measuring the real-time displacement of the upper carriage 3031 relative to the lower carriage 3032.
In operation, the control system sets an initial compression amount, i.e., a precompaction force, of the first spring 3033 by adjusting the screw 3034, and the precompaction force value is measured by the pressure sensing loop 3036. When the cylinder 307 drives the connecting seat 303 to be integrally pressed down, so that the spline head 306 is inserted into the processing module 7 and is pressed, the pressure detection ring 3036 feeds back the current pressure value in real time, and the displacement sensor 3037 feeds back the current compression displacement in real time. The control system receives the current pressure value and the current compression displacement signal measured by the pressure detection ring 3036 and the displacement sensor 3037, compares the current pressure value and the current compression displacement signal with a preset target pressure value and an allowable displacement range, and adjusts the air inflow of the air cylinder 307 through a closed loop so as to control the downward pressing displacement of the upper slide seat 3031, and finally stabilizes the actual pressing force near the target pressure value. In this way, the optimal pressing force which is too high and too low can be automatically applied when the processing module 7 and the support column 503 with different specifications face each other, so that the conical surface 701 of the processing module 7 and the polishing head 607 are prevented from being damaged, and the stability and the processing precision of the clamping of the processing module 7 in the repairing process are ensured.
In the third embodiment, the component code is set on the steel ring of the processing module 7 in a laser etching mode, and the component code is preferably a two-dimensional code, such as a DataMatrix two-dimensional code, and has high information density and strong anti-fouling capability, so that the processing module is suitable for being used in an industrial environment in which oil stains and cutting fluid possibly exist. The component code includes a serial number of the processing module 7, a basic attribute, a current state and a historical state, wherein the serial number is a unique identifier of the processing module 7 and is used for distinguishing the processing module 7 with the same or different specifications, the basic attribute includes a nominal angle, an initial thickness, a delivery date, a material model and the like of the processing module 7, the current state includes a current angle value and a thickness value of the processing module 7, and the historical state includes a historical repair record of the processing module 7, namely a last repair date, angle values before and after a previous repair, an operator, a repair equipment number and the like.
Referring to fig. 12 or 13, the detection unit further comprises a vision module 8 comprising an industrial camera fixedly mounted on the riser face 3011 of the support plate 301 and a mating light source. The resolution of the industrial camera is enough to clearly read DATAMATRIX codes with a small size, the light source is used for providing uniform illumination during scanning, eliminating reflection interference, ensuring the success rate of reading, and the operation process of the vision module 8 is not described herein.
The workflow of this embodiment is as follows:
In step S1, when the conical surface 701 of any processing module 7 needs to be repaired or inspected, the thickness of the current processing module 7 is obtained through a vernier caliper, and then the processing module 7 is placed on the supporting column 503. The vision module 8 is started, and the industrial camera is assisted by the light source, so that the vision module 8 automatically focuses and shoots the component codes on the processing module 7. The control system then retrieves the component information associated with the unique serial number from the local database via the component code.
And S2, importing the thickness of the current processing module 7 into a component code, and comparing the current thickness value H1 with a preset scrapped thickness threshold value H by the control system. If H1 is less than or equal to H, an alarm is immediately sent out at the interface, for example, the tool life is exhausted, the use is forbidden, the lifting module 3 and the angle adjusting module 6 are locked, all subsequent operations are prevented, and the tool is forced to exit circulation. And the risk of failure in the subsequent seat ring repair is radically eliminated. If the tool life is acceptable, i.e., H1> H, then the next step is performed.
Step S3, the angle detection module 9 measures the actual angle alpha 1 of the processing module 7, the control system extracts the nominal angle alpha of the processing module 7 from the component information, the control system compares the real-time angle with the nominal angle, and the absolute deviation delta alpha= |alpha 1-alpha| is calculated;
If delta alpha is less than or equal to 0.3 degrees, the angle precision of the processing module 7 is judged to be good, the direct use requirement is met, the control system imports the current state of the processing module 7 such as the current angle value, the thickness value and the current date and automatically updates the component code, and if delta alpha is more than 0.3 degrees, the control system judges that the processing module 7 needs to be repaired and executes the next repairing action.
Step S4, setting the nominal angle alpha of the current processing module 7 as a target angle of the current operation, adjusting the working end face of the polishing head 607 on the angle adjusting module 6 to the target angle by an operator, firmly locking the working end face by tightening the lock head 6031 of the locking part 603, and executing the repairing process.
Step S5, the angle detection module 9 detects the angle of the repaired conical surface 701, if the conical surface 701 is not qualified, the step S4 is re-executed, if the conical surface is qualified, the direct use requirement is met, the current angle value, the thickness value, the repair date, the operator, the equipment number and other state information of the processing module 7 are imported into the part code, and updating is completed.
It will be apparent that the embodiments described above are merely some, but not all, embodiments of the invention. All other embodiments, which can be made by those skilled in the art based on the embodiments of the present invention without making any inventive effort, shall fall within the scope of the present invention.
