[0026] The embodiment of the present invention relates to an automatic detection device for commutator concave pieces, as Figure 1-7 shown, including a detection table 4. A transfer device 9 is installed at the upper end of the detection table 4. A screening device 11 is installed in front of the transfer device 9 at the upper end of the detection table 4. A conveyor belt 6 and a material distribution device 7 are installed behind the transfer device 9 at the upper end of the detection table 4. A detection device 3 is installed on the left side of the transfer device 9 at the upper end of the detection table 4. The detection device 3 includes a base 5 and a pressing and rotating device. A slide table 22 and a slide table cylinder 14 for driving the horizontal sliding of the slide table 22 are installed at the upper end of the base 5. A limiting table 26 for placing the commutator concave piece 28 is installed on one side of the slide table 22 at the upper end of the base 5. A sensor 13 is installed on the other side of the slide table 22 at the upper end of the base 5. One end of the sensor 13 is in contact with the side wall of the slide table 22. A side pressing seat 23 is installed at the upper end of the slide table 22. A tension spring 12 is installed on the front and rear sides of the limiting table 26 at the upper end of the base 5. One ends of the two tension springs 12 are respectively connected to the two sides of the slide table 22. The pressing and rotating device is located behind the base 5.

[0027] A semi-circular notch 24 is opened on the side of the side pressing seat 23 close to the limiting table 26. A detection rod 25 is installed at the notch 24. The detection rod 25 is made of tungsten steel material.

[0028] A mandrel 27 through which the commutator concave piece 28 passes is vertically installed in the middle of the upper end of the limiting platform 26. A spacer block 15 is installed between the upper end of the base 5 and the limiting platform 26.

[0029] The downward pressing and rotating device includes a column 20, a stepping motor 19 and a downward pressing cylinder 21. A column 20 is vertically installed at the upper end of the detection table 4 and behind the base 5. A lifting plate 17 and a downward pressing cylinder 21 for driving the lifting plate 17 to move up and down are installed on one side of the upper part of the column 20. A rotating shaft 29 arranged vertically and a stepping motor 19 for driving the rotating shaft 29 to rotate are installed at the upper end of the lifting plate 17. A transmission gear 16 is connected to the lower end of the rotating shaft 29. The output shaft of the stepping motor 19 is connected to the upper end of the rotating shaft 29 through a coupling 18.

[0030] The rotating shaft 29 is hollow. A lifting shaft that slides up and down is installed inside the rotating shaft 29. A guiding hole 30 is vertically opened on both sides of the lower part of the rotating shaft 29. The transmission gear 16 is installed at the lower end of the lifting shaft. A guiding member that passes through the two guiding holes 30 is installed at the upper end of the lifting shaft. A spring 31 is sleeved on the lifting shaft between the lower end of the rotating shaft 29 and the transmission gear 16. The guiding member can be an ordinary pin, and the guiding hole 30 is in a strip shape. The cooperation between the inner wall of the rotating shaft 29 and the lifting shaft and the cooperation between the guiding hole 30 and the guiding member can not only ensure the stability of relative sliding, but also not affect the rotation together. At the same time, the rotating shaft 29 and the lifting shaft are elastically connected through the spring 31.

[0031] A baffle 44 is arranged above the middle of the conveyor belt 6. A vibrating disk 8 is arranged at the inlet end of the conveyor belt 6. The material distributing device 7 includes a material distributing cylinder 45 and a material distributing plate 48. A slider 47 and a material distributing cylinder 45 for driving the slider 47 to slide back and forth are installed on the detection table 4. The material distributing plate 48 located on one side of the baffle 44 is installed at the upper end of the slider 47. An extension platform 46 is arranged in front of the material distributing plate 48 at the front end of the conveyor belt 6.

[0032] A track 49 for guiding the commutator concave piece 28 is arranged on the conveyor belt 6.

[0033] First, the commutator concave segments 28 are sorted by the vibrating plate 8 and sent to the conveyor belt 6 one by one. The track 49 on the conveyor belt 6 makes the commutator concave segments 28 neatly arranged one by one. After the commutator concave segments 28 reach the baffle plate 44, the dividing cylinder 45 controls the dividing plate 48 to send the commutator concave segments 28 one by one to the extension platform 46. Then the transfer device 9 puts the commutator concave segments 28 on the limit table 26. The core shaft 27 at the upper end of the limit table 26 passes through the commutator concave segments 28. Then the pressing cylinder 21 controls the transmission tooth 16 to press down on the upper end of the commutator concave segments 28. The stepping motor 19 rotates to drive the commutator concave segments 28 to rotate around the core shaft 27. Then the slide The table cylinder 14 releases the slide 22 connected to the tension spring 12. A side pressure seat 23 is installed on the upper end of the slide 22. The detection rod 25 on the side pressure seat 23 is pressed on the outer circle detection part of the commutator concave piece 28 under the action of the tension spring 12. The slight jump caused by the rotation of the commutator concave piece 28 is transmitted to the detection rod 25, and then transmitted to the sensor 13 through the slide 22. The sensor 13 feeds back the detected signal to the PLC main control program, automatically judges the input signal, and distinguishes qualified products from defective products. After that, the transfer device 9 takes the detected commutator concave piece 28 and places it on the brushing platform 32. The brushing device 11 places the qualified products and defective products separately.

[0034] The transfer device 9 includes a lifting cylinder 38, a rotating cylinder 39 and two mechanical gripper devices. A lifting cylinder 38 is vertically installed at the lower end of the detection platform 4. The piston rod of the lifting cylinder 38 passes through the upper end surface of the detection platform 4 and is connected to the rotating cylinder 39. Two mechanical gripper devices are arranged around the upper part of the rotating cylinder 39. The mechanical gripper device includes a bidirectional cylinder 40 and an air claw 41. An air claw 41 is connected to each end of the bidirectional cylinder 40. The air claw 41 is clamped or released by the bidirectional cylinder 40, the rotating cylinder 39 controls the rotation of the two mechanical gripper devices, and the lifting cylinder 38 controls the lifting of the two mechanical gripper devices. One mechanical gripper device places the commutator concave plate 28 on the extension platform 46 onto the limit platform 26, and the other mechanical gripper device places the commutator concave plate 28 on the limit platform 26 onto the brushing platform 32.

[0035] A guide sleeve 42 and a guide rod 43 that cooperate with each other are arranged between the upper end of the lifting cylinder 38 and the rotating cylinder 39, and between the pressing cylinder 21 and the lifting plate 17, so as to effectively ensure the stability of the up and down lifting.

[0036] The described screening device 11 includes a screening platform 32, a screening cylinder 34, and a screening push plate 35. One side of the screening platform 32 is provided with a blanking ramp 33. A screening cylinder 34 is horizontally arranged in front of the screening platform 32. One end of the piston rod of the screening cylinder 34 is connected to a screening push plate 35, which is located above the screening platform 32. Below the other side of the screening platform 32, a placement box 10 is installed at the upper end of the detection table 4. At the upper end of the detection table 4, a discharge hole 2 is vertically opened below the blanking ramp 33, and a discharge inclined pipe 1 is connected to the lower port of the discharge hole 2.

[0037] The detected commutator concave pieces 28 are taken away and placed on the screening platform 32. The screening cylinder 34 will push the qualified products onto the blanking ramp 33 and finally out through the discharge inclined pipe 1. The unqualified products are pushed into the placement box 10, thus completing the automatic detection of the outer circle concave pieces of the commutator.

[0038] A positioning cylinder 36 is vertically installed below the screening platform 32, and a through hole 37 for the piston rod of the positioning cylinder 36 to pass through is opened on the screening platform 32. In the initial state, the piston rod of the positioning cylinder 36 extends, and the detected commutator concave pieces 28 are sleeved on the piston rod of the positioning cylinder 36, which can ensure that the commutator concave pieces 28 do not slide out of the screening platform 32. Then, the piston rod of the positioning cylinder 36 contracts, and the screening cylinder 34 can classify the commutator concave pieces 28.

[0039] The present invention can automatically complete the detection and sorting of the commutator concave pieces, greatly reducing the product missed detection and misdetection caused by human factors. At the same time, it improves the detection efficiency and reduces the labor intensity of employees. The present invention realizes the automatic detection function for the concave pieces on the outer circle surface of the commutator.
