[0023] An automatic detection method for a car shock absorber connecting ring after chamfering, the specific steps are as follows: S1. Feeding: The feeding device is a vibrating plate feeding machine. The chamfered connecting pipes are placed in the vibrating plate and enter the transition channel along the feeding channel. The cylinder E is retracted, the block moves downward, and the transition channel and the waiting channel are unblocked. The cylinder D is retracted, and the push-out plate pushes the two connecting pipes into the waiting channel. S2. Transfer: When cylinder A extends, the left clamping rod and the right clamping rod move to both sides of the connecting pipe above the material channel. When cylinder B and cylinder C retract, the left clamping plate and the right clamping plate move toward each other, and the left clamping rod and the right clamping rod approach and clamp the connecting pipe. The electric lead screw linear slide module drives the connecting pipe to move along the length direction of the material channel, thereby realizing the sequential movement of the connecting pipes in pairs on the material channel for feeding, chip blowing, height detection, outer diameter detection, visual inspection and good product output stations; S3, chip blowing: When the connecting pipe reaches the chip blowing station, the cylinder F moves downward, and the blowing nozzle is aimed at the top surface of the connecting pipe to blow air, and the aluminum chips generated during chamfering are dropped and collected in the chip collecting box; S4, height detection: When the connecting pipe is grabbed to the height detection station, the cylinder P moves downward, the pressure block presses the top of the connecting pipe, and the measuring rod contacts the top of the connecting pipe. The displacement sensor feeds back the data to the controller, and the controller determines whether its height dimension is qualified according to the set threshold value. After the detection of a connecting pipe in the same group is completed, the cylinder G drives the displacement sensor to move along the length direction of the material channel and detects whether the height dimension of another connecting pipe is qualified. S5, outer diameter detection: The connecting pipes that have passed the detection are caught and placed on the first tray. Under the action of the cylinder I, the first pressure head moves downward and presses the top of the connecting pipe. The light of the two groups of opposite-shooting sensors is just tangent to the two ends of the connecting pipe. The first motor drives the first pressure head to rotate, and the first pressure head drives the connecting pipe to rotate 360°. During the rotation process, if the two beams of light are not blocked, the controller determines that the outer diameter is qualified. If the light is blocked, it means that the connecting pipe is eccentric, and the controller determines that it is unqualified. After the detection of a connecting pipe in the same group is completed, the cylinder H will drive the two groups of opposite-shooting sensors to move along the length direction of the material channel and detect whether the outer diameter of another connecting pipe is qualified. S6, visual inspection: The connecting pipes with inspected outer diameters are grabbed and placed on the second pallet. Under the action of the cylinder M, the second pressure head moves downward and presses the top of the connecting pipe. The industrial camera takes an image of the connecting pipe. The second motor drives the second pressure head to rotate. The second pressure head drives the connecting pipe to rotate 360°. During the rotation process, the controller will determine whether there are chamfers and obvious defects such as cracks and pits on the surface based on the image sent back. After the inspection of a connecting pipe in the same group is completed, the cylinder J will drive the industrial camera to move along the length direction of the material channel and inspect whether the surface of another connecting pipe is qualified. S7, unloading of defective products: If one of the height, outer diameter and appearance of the connecting pipe is unqualified, the controller will judge it as a defective product; at this time, cylinder K and cylinder Q are extended successively, the lever is inserted into the center of the connecting pipe, cylinder K is retracted, and the connecting pipe is pulled to the defective product entrance of the collecting box and falls into the collecting box; S8, good product unloading: If the height, outer diameter and appearance of the connecting pipe are all qualified, the controller will judge it as a good product; the clamp will grab it and place it on the belt conveyor, and discharge it from the discharge port.

A plurality of left clamping rods and a plurality of right clamping rods are installed on a left clamping plate and a right clamping plate, and are clamped and released by two cylinder drives. This saves a plurality of manipulators, saves costs, and saves installation space.

[0026] The device and method for automatically detecting the chamfered connecting pipe of the automobile shock absorber of the present invention can blow away the aluminum chips generated by the connecting pipe when the connecting pipe is chamfered, thereby ensuring that the detection result is more accurate.

[0027] The automatic detection device and detection method for automobile shock absorber connecting pipes after chamfering of the present invention can realize the detection of two connecting pipes in the same group through translation, and improve the detection efficiency.

The chamfered connecting pipe 11 is placed in the vibrating plate and enters the transition channel 404 along the feeding channel 405; the cylinder E407 is retracted, the stopper 408 moves downward, and the transition channel 404 and the waiting channel 401 are unblocked; the cylinder D406 is retracted, and the push plate 402 pushes the two connecting pipes 11 into the waiting channel 401; S2. Transfer: When the cylinder A306 extends, the left clamping rod 302 and the right clamping rod 303 move to both sides of the connecting pipe 11 above the material channel 2. When the cylinder B307 and the cylinder C308 retract, the left clamping plate 309 and the right clamping plate 310 move toward each other, the left clamping rod 302 and the right clamping rod 303 approach and clamp the connecting pipe 11, and the electric lead screw linear slide module 304 drives the connecting pipe 11 to move along the length direction of the material channel 2, thereby realizing the sequential movement of the connecting pipes 11 in pairs on the material channel 2 for feeding, chip blowing, height detection, outer diameter detection, visual detection and good product output stations; S3, chip blowing: when the connecting pipe 11 reaches the chip blowing station, the cylinder F504 moves downward, and the blowing nozzle 503 blows air toward the top surface of the connecting pipe 11, and the aluminum chips generated during chamfering are dropped and collected in the chip collecting box 506; S4, height detection: When the connecting pipe 11 is grabbed to the height detection station, the cylinder P604 moves downward, the pressing block 610 presses the top of the connecting pipe 11, and the measuring rod 611 contacts the top of the connecting pipe 11. The displacement sensor 603 feeds back data to the controller, and the controller determines whether its height dimension is qualified according to the set threshold value; after the detection of a connecting pipe 11 in the same group is completed, the cylinder G605 drives the displacement sensor 603 to move along the length direction of the material channel 2, and detects whether the height dimension of another connecting pipe 11 is qualified; S5, outer diameter detection: the connecting pipe 11 that has passed the detection is grabbed and placed on the first tray 703. Under the action of the cylinder I707, the first pressure head 712 moves downward and presses the top of the connecting pipe 11. The light of the two sets of opposite-shooting sensors 701 is just tangent to the two ends of the connecting pipe 11. The first motor 710 drives the first pressure head 712 to rotate, and the first pressure head 712 drives the connecting pipe 11 to rotate 360°. During the rotation process, if the two beams of light are not blocked, the controller determines that the outer diameter is qualified. If the light is blocked, it means that the connecting pipe 11 is eccentric, and the controller determines that it is unqualified. After the detection of a connecting pipe 11 in the same group is completed, the cylinder H704 will drive the two sets of opposite-shooting sensors 701 to move along the length direction of the material channel 2, and detect whether the outer diameter of the other connecting pipe 11 is qualified; S6, visual inspection: The connecting pipe 11 with the inspected outer diameter is grabbed and placed on the second tray 803. Under the action of the cylinder M809, the second pressing head 808 moves downward and presses the top of the connecting pipe 11. The industrial camera 802 takes an image of the connecting pipe 11. The second motor 806 drives the second pressing head 808 to rotate. The second pressing head 808 drives the connecting pipe 11 to rotate 360°. During the rotation process, the controller will determine whether there is a chamfer based on the image sent back, and whether there are obvious defects such as cracks and pits on the surface; after the inspection of a connecting pipe 11 in the same group is completed, the cylinder J804 will drive the industrial camera 802 to move along the length direction of the material channel 2, and inspect whether the surface of another connecting pipe 11 is qualified; S7, unloading of defective products: If one of the height, outer diameter and appearance of the connecting pipe 11 is unqualified, the controller determines it as a defective product; at this time, the cylinder K903 and the cylinder Q904 extend successively, the lever 902 is inserted into the center of the connecting pipe 11, the cylinder K903 retracts, and the connecting pipe 11 is pulled to the defective product entrance of the collecting box 901 and falls into the collecting box 901; S8, good product unloading: If the height, outer diameter and appearance of the connecting pipe 11 are all qualified, the controller determines that it is a good product; the clamping claw grabs it and puts it on the belt conveyor 1001, and discharges it from the discharge port.
