[0052] Furthermore, the loading mechanism 100 includes a loading belt conveyor 101, the loading end of the loading belt conveyor 101 is provided with a loading tray 102, and the top of the unloading end 102 is provided with an air claw 103, the air claw 103 is provided with a fifth linear reciprocating motion mechanism 104 for controlling its vertical up and down movement, and the fifth linear reciprocating motion mechanism 104 is provided with a sixth linear reciprocating motion mechanism 105 for controlling its horizontal left and right movement.

[0053] Furthermore, the unloading mechanism 200 includes a unloading belt conveyor 201 , and a unloading tray 202 is provided at the unloading end of the unloading belt conveyor 201 ; a barcode scanning gun 203 is provided on the side of the unloading belt conveyor 201 .

[0054] In this embodiment, the piston cylinder to be inspected is as follows Figure 10 The upright state shown is placed in the loading tray 102. Through the rotation of the loading tray 102 and the fixed guide groove on the tray, the workpiece is pushed forward to supply the loading belt conveyor 101. The workpiece is grasped by the air claw 103 and sent to the positioning mechanism 300.

[0055] The circumferential rotating platform 303 on the positioning mechanism 300 rotates with the workpiece, and the first position sensor determines whether the workpiece has rotated into position. The first grasping mechanism is used to grasp the workpiece on the positioning mechanism 300 and move it to the cleaning mechanism 400.

[0056] The brush bar 403 on the cleaning mechanism 400 rotates at high speed before rising to penetrate the workpiece and clean its inner hole. During this process, the cleaning pressure block 404 moves downward from above to press the workpiece, and the workpiece height is detected by the second position sensor 407. The first gripping mechanism grabs the workpiece on the cleaning mechanism 400 and moves it to the thread detection mechanism 500.

[0057] The thread gauge 503 on the thread inspection mechanism 500 rotates at a low speed before ascending and inserting into the workpiece to inspect the internal threads. During this process, the workpiece is held down by a thread inspection pressure block 504 that moves downward from above. The first gripping mechanism grabs the workpiece from the thread inspection mechanism 500 and brings it to the first waste discharge mechanism 600 for determination of its passing status. If qualified, the workpiece is conveyed to the first good product belt conveyor 602, where it is then taken to the second gripping mechanism 1700 and brought to the inner diameter measurement mechanism 700.

[0058] The inner diameter measuring mechanism 700 exhausts air through the outlet on the inner diameter profiling positioning pin 702 inserted into the workpiece. The pressure feedback from the air source is compared with the pressure feedback from the standard part. If the error is within the set range, the workpiece is considered qualified; if the error is outside the set range, the workpiece is considered unqualified. The second gripping mechanism 1700 grabs the workpiece on the inner diameter measuring mechanism 700 and transfers it to the outer diameter measuring mechanism 900. (Unqualified workpieces are sent to the second waste discharge mechanism 800 for discharge.)

[0059] Before being sent to the outer diameter measuring mechanism 900 , the workpiece is turned over and placed in a tilted state. This action is performed by the turning mechanism on the second waste discharge mechanism 800 .

[0060] The outer diameter measuring mechanism 900 detects the workpiece by inserting its side into the outer diameter measuring positioning slot 902. Since the workpiece's outer wall is close to the air outlet, the feedback pressure from the test air source is compared with the feedback pressure from the reference part. If the error is within the set range, the workpiece is considered acceptable; if the error is outside the set range, the workpiece is considered unacceptable. The second gripping mechanism 1700 then grabs the workpiece from the outer diameter measuring mechanism 900 and transfers it to the first contour measuring mechanism 1100. (Unacceptable workpieces are then sent to the third waste discharge mechanism 1000 for removal.)

[0061] The first contour measurement mechanism 1100 uses an industrial camera to capture images of the end face's outer and inner contours. A computer then performs internal measurements and calculations to determine if the workpiece has passed the test. The second gripping mechanism 1700 grabs the workpiece from the first contour measurement mechanism 1100 and transfers it to the second contour measurement mechanism 1300. (Defective workpieces are sent to the fourth waste discharge mechanism 1200 for removal.)

[0062] The second contour measurement mechanism 1300 uses an industrial camera to capture images of the workpiece's side features. A computer performs internal measurements and calculations to determine if the workpiece has passed the test. The second gripping mechanism 1700 grabs the workpiece from the second contour measurement mechanism 1300 and brings it to the appearance inspection mechanism 1400.

[0063] The appearance inspection mechanism 1400 also uses an industrial camera to capture images of the workpiece's side features. A computer then compares these images to determine if the outer wall has machining defects, thereby determining whether the workpiece has passed the standard. The second gripping mechanism 1700 then grabs the workpiece from the appearance inspection mechanism 1400 and transfers it to the unloading mechanism 200 (rejected parts are sent to the fifth waste discharge mechanism 1500 for removal).

[0064] The unloading mechanism 200 realizes automatic unloading via the unloading belt conveyor 201 ; during this period, the barcode scanner 203 collects the information in the QR code on the workpiece.

[0065] Among them, during the detection action of the second contour measurement mechanism 1300 and the appearance detection mechanism 1400, the first turning roller 1301 and the second turning roller 1302 will rotate, and the workpiece will also rotate; the third turning roller 1401 and the fourth turning roller 1402 will rotate, and the workpiece will also rotate.

[0066] The first power assembly 1303 and the second power assembly 1403 both include a gear pair and a motor.

[0067] The rotating mechanism may be a rotating cylinder or an existing mechanism that performs the same function.

[0068] The linear reciprocating motion mechanism may be a push rod cylinder, or an existing mechanism that performs the same function.

[0069] The multi-process detection equipment for brake piston cylinders for new energy vehicles involved in the present invention realizes circumferential correction of the workpiece to be inspected by setting a positioning mechanism between automatic loading and automatic unloading operations; realizes internal cleaning of the workpiece to be inspected by setting a cleaning mechanism; realizes thread processing accuracy detection of the workpiece to be inspected by setting a thread detection mechanism; realizes inner diameter detection of the workpiece to be inspected by setting an inner diameter measuring mechanism; realizes outer diameter detection of the workpiece to be inspected by setting an outer diameter measuring mechanism; realizes outer contour processing accuracy detection of the workpiece to be inspected by setting a contour measuring mechanism; realizes appearance detection of the workpiece to be inspected by setting an appearance detection mechanism, integrating multiple process detections into one, with a high degree of automation, convenient operation, complete overall functions and strong practicality.
