Description

Technical Field

[0001] This utility model belongs to the technical field of commutator production equipment, and in particular relates to a testing device for commutator production. Background Technology

[0002] A commutator, also known as a "rectifier," is an important component of the armature of a DC motor and an AC commutator motor. It consists of many copper plates separated by mica sheets, forming a cylindrical or disc shape. Each copper plate is connected to several armature winding elements. When the armature rotates, the copper plates successively contact the fixed brushes. In a DC motor, the alternating current in the armature winding is converted into direct current between the brushes through the brushes and the commutator.

[0003] In the production process of commutators, the inspection process is a key link to ensure product quality. Patent No. CN209263856U discloses a commutator inspection device. This utility model places the commutator inside the container to facilitate the measurement of the length of the lower end of the shaft. Through the elastic force of the pressure plate and the spring, it is easy to see how much the shaft exceeds the limit, which facilitates rework. However, this patent can only inspect a single commutator at a time, which is inefficient. It also requires a lot of manual operation according to the scale, which reduces the working efficiency of the device. Manual comparison inspection is also prone to errors. Utility Model Content

[0004] The purpose of this invention is to provide a testing device for commutator production to solve the problems of low efficiency caused by only being able to test a single commutator at a time.

[0005] This utility model achieves the above-mentioned objectives through the following technical solution: It includes a base plate, on one side of the upper surface of which several commutators are movably connected. Each commutator is movably connected to a connecting plate on one side. Limiting plates are provided at both ends of the connecting plate near the commutators. A first electric telescopic rod is provided on the side of the connecting plate away from the limiting plates. Connecting columns are provided at both ends of the upper surface of the base plate. A lifting plate of matching length is provided between two connecting columns. A scale strip is provided on the surface of each connecting column near the commutators. A controller is provided on one side of each connecting column. Several indicator lights are arranged above the lifting plate. Several sorting devices are arranged below the lifting plate. A second electric telescopic rod is provided at both ends of the upper surface of the lifting plate.

[0006] Furthermore, the sorting device includes a placement slot, with lifting slots on both sides of the placement slot. A movable plate of the same length and width is movably connected inside the placement slot. A slider is provided at the upper end of both sides of the movable plate, and a sensor is provided at the top of the placement slot.

[0007] Furthermore, the placement slot is located below the lifting plate, the indicator lights are located above the placement slot and the number of both is the same, and the movable plate is movably connected to the top of the commutator.

[0008] Furthermore, the sensor is located above the movable plate with a gap between them, the slider is movably connected inside the lifting groove and both have the same length and width, and the length of the lifting groove is less than the length of the placement groove.

[0009] Furthermore, the limiting plate and the connecting plate are movably connected to the upper surface of the base plate, and the first electric telescopic rod is fixed to the upper surface of the base plate.

[0010] Furthermore, the connecting plates are all located between the connecting columns, and the lifting plate is movably connected between two of the connecting columns.

[0011] Furthermore, the second electric telescopic rod is fixedly connected to the connecting column.

[0012] Beneficial effects: This utility model is reasonably designed and has the following beneficial effects:

[0013] 1. By setting up multiple classification devices and indicator lights, multiple commutators can be height detected simultaneously. The second electric telescopic rod drives the lifting plate to descend, and multiple commutators can be detected in one operation, which improves detection efficiency compared with the traditional single detection method.

[0014] 2. By utilizing the coordinated operation of sensors, movable plates, and indicator lights, it is possible to accurately determine whether the commutator height meets the standard. When the commutator height is too high, the movable plate contacts the sensor, and the corresponding indicator light illuminates. When the lifting plate descends to the compliant height, the indicator light above the commutator that is too low will not illuminate. This intuitive method prompts the staff, reduces human judgment errors, and ensures the accuracy of the test results.

[0015] 3. The scale strip on the connecting column, in conjunction with the design of the lifting plate, allows operators to adjust the lowering height of the lifting plate according to commutators of different sizes and heights, enabling the testing device to flexibly adapt to the testing needs of various commutator specifications.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Combination Figures 1 to 3 The device shown is a testing device for commutator production, comprising a base plate 1. Several commutators 2 are movably connected to one side of the upper surface of the base plate 1. A connecting plate 7 is movably connected to one side of each commutator 2. Limiting plates 8 are provided at both ends of the connecting plate 7 near the commutator 2. A first electric telescopic rod 9 is provided on the side of the connecting plate 7 away from the limiting plates 8. Connecting columns 3 are provided at both ends of the upper surface of the base plate 1. A lifting plate 13 of matching length is provided between two connecting columns 3. Scale strips 10 are provided on the surface of the connecting columns 3 near the commutator 2. A controller 11 is provided on one side of the connecting columns 3. Several indicator lights 12 are arranged above the lifting plate 13. Several sorting devices 4 are arranged below the lifting plate 13. Second electric telescopic rods 6 are provided at both ends of the upper surface of the lifting plate 13. The control connection method between the electric telescopic rods and the controller in this invention is existing technology and will not be described. The sensors, electric telescopic rods, and indicator lights are also existing technology and will not be specifically described.

[0023] The sorting device 4 includes a placement slot 41, with lifting slots 43 on both sides of the placement slot 41. A movable plate 42 of the same length and width is movably connected inside the placement slot 41. A slider 44 is provided at the upper end of both sides of the movable plate 42. A sensor 45 is provided at the top of the placement slot 41.

[0024] The placement slot 41 is located below the lifting plate 13, and the indicator lights 12 are located above the placement slot 41 and the number of both is the same. The movable plate 42 is movably connected above the commutator 2, and the number of indicator lights is the same as the number of commutators.

[0025] The sensor 45 is located above the movable plate 42 and there is a gap between the two. The slider 44 is movably connected inside the lifting groove 43 and the two have the same length and width. The length of the lifting groove 43 is less than the length of the placement groove 41.

[0026] The limiting plate 8 and the connecting plate 7 are movably connected to the upper surface of the base plate 1, and the first electric telescopic rod 9 is fixed to the upper surface of the base plate 1.

[0027] The connecting plates 7 are all located between the connecting columns 3, and the lifting plate 13 is movably connected between the two connecting columns 3; the scale bar 10 allows for manual comparison to check whether the height of the lifting plate 13 descends is compliant.

[0028] The second electric telescopic rod 6 is fixedly connected to the connecting column 3.

[0029] Working principle: In use, the commutator is first placed between the two limit plates 8. Then, the controller starts the second electric telescopic rod 6 to drive the lifting plate 13 to descend. During the descent, the movable plate 42 will contact the commutator 2. When it does not descend to the specified height (i.e., the normal height of the commutator), the movable plate 42 will contact the excessively high commutator. The movable plate 42 will then contact the sensor 45 through the slider 44 and the lifting groove 43. The sensor 45 will cause the indicator light 12 to light up to provide a warning. The employee will then move the indicator light below the lit indicator light. The commutator is removed; when the lifting plate descends to the appropriate height, the movable plate 42 will cooperate with the lifting groove 43 through the slider 44 and contact the sensor 45. The sensor 45 will cause the indicator light 12 to emit a prompt. The employee will remove the commutator below the indicator light that has not lit up. Then the lifting plate rises, and the first electric telescopic rod 9 will drive the connecting plate 7 to move, which will move the qualified commutator out of the base plate for collection. This can effectively screen out commutators that do not meet the height standard, and can also test multiple commutators at one time, as well as commutators of different sizes and heights.
