[0002] During the production process of the commutator, the size of its inner hole needs to be inspected to ensure the accuracy of the size. The existing inspection method is a backward production process that relies on manual inspection of products with go and no-go gauges. Due to the particularity of the inner hole of the commutator product, the commonly used electronic plug gauges and visual image inspection methods on the market cannot accurately judge the quality of the commutator inner hole, and thus cannot provide customers with products with stable shaft insertion force. In addition, the commutator also needs to undergo a pressure test. The pressure test requires testing the inter-segment pressure and the segment shaft pressure of the commutator segments on the commutator. Currently, manual testing is used, which is cumbersome, inefficient, and prone to missed inspections of commutator segments. Utility Model Content

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0022] The utility model aims to solve the problems of low efficiency of current inner hole size detection and pressure resistance detection, and easy missed detection and false detection. Figure 1-6 As shown, the following technical scheme is provided: a commutator inner hole and pressure resistance comprehensive detection equipment, including a machine table 1, the inner hole detection component and the pressure resistance detection component are respectively arranged on both sides of the upper end of the machine table 1, the inner hole detection component includes a straight workbench 29, the first end of the straight workbench 29 is provided with a commutator feeding and conveying guide rail 6, the second end of the straight workbench 29 is provided with a pressure resistance transfer manipulator 13, one side of the straight workbench 29 is provided with an inner hole cleaning component 22, a first inner hole detection station 2 and a second inner hole detection station 3 in sequence from the first end to the second end, the other side of the straight workbench 29 is provided with a first feeding movable table 21 that moves horizontally along the length direction of the straight workbench 29, and the first feeding movable table 21 is driven by a first cylinder 9 at one end thereof to move along the slide rail 20 The first loading movable platform 21 is provided with a second loading movable platform 18 driven by a second cylinder 8 to move toward the straight workbench 29 on the upper side, and a plurality of material shifting forks 19 are provided on one end of the second loading movable platform 18 facing the straight workbench 29. The pressure resistance detection component includes a dividing turntable 11, and a plurality of commutator positioning mandrels 24 are evenly arranged on the upper side of the dividing turntable 11. A film shaft pressure resistance detection device 4 and an inter-film pressure resistance detection device 5 are arranged side by side on one side of the dividing turntable 11. The film shaft pressure resistance detection device 4 and the inter-film pressure resistance detection device 5 are both connected to a pressure resistance detector 15. The pressure resistance detector 15 inputs voltage to the commutator through the film shaft pressure resistance detection device 4 and the inter-film pressure resistance detection device 5. A picking robot 17 is centrally installed on the other side of the dividing turntable 11.

[0023] Specifically, the length of the straight workbench 29 is greater than the length of the arrangement position of the first inner hole inspection station 2 and the second inner hole inspection station 3. A plurality of workstations can be arranged on one side of the first inner hole inspection station 2 and the second inner hole inspection station 3 near the second end of the straight workbench 29. The additional workstations can be used for unloading defective products, and can also be used to increase the number of inner hole inspection stations.

[0024] Among them, the inner hole cleaning component 22 can clean the inner hole of the commutator. There are many ways to clean it. It can be done by blowing, such as installing a blowing hole at the bottom of the straight workbench 29 to blow air towards the inner hole of the commutator. A lifting soft-bristled rod can also be set on the straight workbench 29, which can be inserted into the inner hole of the commutator to clean impurities on the surface of the inner hole. This can be set as needed.

[0025] The first loading movable table 21 moves laterally under the drive of the first cylinder 9, driving the material shifting fork 19 to move laterally, and synchronously moves the commutator placed on the straight bar workbench 29 toward the second end direction of the straight bar workbench 29. When the material shifting fork 19 needs to return, the second loading movable table 18 needs to be pulled back under the drive of the second cylinder 8 to disengage the material shifting fork 19 from the commutator. In this way, the alternating cooperation of the first loading movable table 21 and the second loading movable table 18 is realized, and multiple commutators are sent forward.

[0026] The commutator positioning mandrel 24 of the dividing turntable 11 is used for the commutator to be sleeved and positioned. Six commutator positioning mandrels 24 can be set on the dividing turntable 11. One commutator positioning mandrel 24 cooperates with the pressure-resistant transfer robot 13 to place the commutator. Two commutator positioning mandrels 24 correspond to the sheet shaft pressure-resistant detection device 4 and the inter-sheet pressure-resistant detection device 5 respectively. One commutator positioning mandrel 24 corresponds to the picking robot 17, and two commutator positioning mandrels 24 are respectively set on both sides of the commutator positioning mandrel 24 as transition stations.

[0027] The withstand voltage tester 15 can be arranged above the film shaft withstand voltage test device 4 and the inter-sheet withstand voltage test device 5. The film shaft withstand voltage test device 4 and the inter-sheet withstand voltage test device 5 are both installed on the bracket 16 on one side of the dividing turntable 11. The film shaft withstand voltage test device 4 includes a third cylinder 42 and a film shaft detection spring sheet 41 driven by the third cylinder 42 for lifting and lowering, wherein a spring is arranged on the outer side of the upper end of the film shaft detection spring sheet 41, which can press the hook foot at the top of the commutator on the commutator positioning core shaft 24. At the same time, the withstand voltage tester 15 inputs the set voltage to the product and determines whether the product film shaft detection is qualified.

[0028] like Figure 5As shown, as a specific embodiment of the inter-segment pressure resistance detection device 5, the inter-segment pressure resistance detection device 5 includes a fourth cylinder 53 and a rotating motor 54 driven by the fourth cylinder 53 to lift and lower, the lower end main shaft of the rotating motor 54 is connected with the inter-segment detection transmission petal part 52, and a plurality of inter-segment detection detection probes 51 that can move laterally are installed on one side of the inter-segment detection transmission petal part 52. During detection, the fourth cylinder 53 drives the inter-segment detection transmission petal part 52 to descend, and the inter-segment detection transmission petal part 52 is downwardly buckled on the hook foot of the commutator, and the rotating motor 54 drives the product to rotate at a uniform speed. The inter-segment detection detection probe 51 can be pushed against the commutator segment on the outer circle of the product by the push of the cylinder inside it, and the pressure resistance detector 15 inputs a set voltage to the product and determines whether the inter-segment detection of the product is qualified.

[0029] In order to sort the commutators after the withstand voltage test, Figure 5 As shown, defective product discharge trough 12 and qualified product discharge trough 10 are respectively provided on both sides of the picking robot 17, and discharge channels are provided at the front and rear of the defective product discharge trough 12, and a defective product sorting cylinder 33 is provided on one side of the defective product discharge trough 12, and a material shifting rod 23 arranged front and back is provided on the upper side of the defective product discharge trough 12, and the material shifting rod 23 is connected to the extension rod of the defective product sorting cylinder 33, and the defective product sorting cylinder 33 can be moved back and forth to classify the defective products placed on the defective product discharge trough 12 according to whether the inter-sheet detection is unqualified or the sheet axis detection is unqualified, thereby greatly improving the sorting of the detection results.

[0030] In this embodiment, if Figure 6 As shown, the first inner hole inspection station 2 and the second inner hole inspection station 3 both include a plug gauge guide sleeve 28 located above the straight workbench 29, a through gauge 26 is arranged at the center of the plug gauge guide sleeve 28, and the through gauge 26 is driven to rise and fall by the inner hole inspection cylinder 27 at its upper end. During inspection, the inner hole inspection cylinder 27 on the first inner hole inspection station 2 pushes the through gauge 26 thereon along the plug gauge guide sleeve 28 into the inner hole of the product. If the through gauge 26 can pass through the product smoothly under the set pressure, the product is qualified and will be transferred to the second inner hole inspection station 3. The through gauge 26 at this station is used to detect whether there is a large hole at the upper end of the product, and the qualified products will be transferred to the next station in turn.

[0031] In order to sort out the unqualified products detected by inner hole, Figure 4 and 6As shown, a defective product unloading push plate 25 is provided at the bottom of the first inner hole detection station 2 and the second inner hole detection station 3 corresponding to the straight workbench 29. The defective product unloading push plate 25 is pushed by the defective product pushing cylinder 14 on one side of the straight workbench 29 to push the commutator that fails the inner hole detection into the defective product box 31 below the other side of the straight workbench 29.

[0032] In order to enable the commutators on the commutator loading and conveying guide rail 6 to be moved one by one onto the straight workbench 29, the commutator loading and conveying guide rail 6 is arranged at a right angle to the straight workbench 29, and a push rod 7 is provided at one end of the straight workbench 29 along the length direction. The push rod 7 is driven by the loading cylinder 32 to push the commutators on the commutator loading and conveying guide rail 6 onto the straight workbench 29 one by one.
