Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of commutators, and particularly relates to a commutator chip - missing detection device. Background Technique
[0002] As an important component on the armature of an electric motor, the commutator is mainly cylindrical and disc - shaped, and is composed of many copper sheets separated by mica sheets. Each copper sheet is connected to several elements. When the armature rotates, the copper sheets successively come into contact with the fixed carbon brushes.
[0003] In the prior art, such as a commutator chip - missing detection device with the patent number CN219923757U, includes: a detection camera for detecting whether the commutator is missing chips; an ink - jet assembly placed on one side of the detection camera for marking the chip - missing positions of the commutator; the utility model detects the commutator by using the detection camera, marks the defective products with the ink - jet assembly, and then the defective - product pushing assembly pushes out the defective products, realizing the detection, marking and collection of the commutator. However, in the existing commutator chip - missing detection device, when detecting the commutator, it detects one by one, so there is a situation of low working efficiency. Therefore, a commutator chip - missing detection device is proposed. Content of the Utility Model
[0004] In view of this, the embodiments of the present utility model hope to provide a commutator chip - missing detection device to solve or alleviate the technical problems existing in the prior art. By installing the first electric push rod, it can push multiple detection components to slide, so that the multiple detection components after sliding can simultaneously detect multiple commutators, thereby enabling the high - device to simultaneously detect multiple commutators, and thus making the working efficiency of the device higher.
[0005] The technical solution of the embodiments of the present utility model is realized as follows:
[0006] A commutator chip - missing detection device includes a base, on which a fixed frame and a second electric push rod are fixedly installed. Two clamping components are slidably arranged in a sliding fit. The clamping component includes two clamping frames and two springs fixedly installed between the clamping frames. The output end of the second electric push rod is fixedly installed with a sliding frame that is slidably arranged with the four clamping frames. A first electric push rod is fixedly installed on the fixed frame, and the output end of the first electric push rod is fixedly installed with multiple detection components. The detection component includes a sliding seat, multiple detection pieces slidably arranged inside the sliding seat. A bolt is in threaded fit with the sliding seat. An extrusion piece is arranged below the bolt, and a rubber piece is arranged below the extrusion piece.
[0007] Preferably, the base is of an inverted U-shaped structure. Two guiding strips for guiding the two ends of the four clamping frames are fixedly installed on the upper surface of the base. Oblique angles are formed on the sides of the four clamping frames close to each other. The formation of the oblique angles facilitates the sliding frame to push the clamping frames to slide away, facilitating the removal of the commutator.
[0008] Preferably, four pushing protrusion parts respectively fitting with the eight oblique angles are arranged on the sliding frame. Two receiving seats are fixedly installed on the base. The output end of the second electric push rod penetrates through the base. When the pushing protrusion parts extrude the clamping frames, the pushing protrusion parts slide upward at this time, and the two clamping frames slide away from each other at this time, facilitating the placement of a new commutator or the removal of the commutator that has been detected.
[0009] Preferably, the two guiding strips are both of an L-shaped structure. The two receiving seats are respectively located between the four clamping frames. The installation of the guiding strips can guide the clamping frames during the sliding process, making the sliding of the clamping frames smoother.
[0010] Preferably, the fixing frame is of an inverted U-shaped structure. A plurality of return pieces corresponding to the plurality of detection components are fixedly installed on the fixing frame. The output end of the first electric push rod is fixedly installed with a connecting strip. The plurality of detection components are fixedly installed on the connecting strip. The installation of the connecting strip facilitates connecting the plurality of detection components together to detect the commutator.
[0011] Preferably, a damping fit exists between the plurality of detection pieces and the rubber pieces. The plurality of detection pieces are all located below the return pieces. The installation of the return pieces facilitates the plurality of detection pieces after detecting the commutator to return to the same height again.
[0012] Due to the adoption of the above technical solutions in the embodiments of the present invention, it has the following advantages:
[0013] 1. By installing the first electric push rod in the present invention, the plurality of detection components can be pushed to slide, so that the plurality of detection components after sliding can simultaneously detect a plurality of commutators, enabling the high device to simultaneously detect a plurality of commutators, thereby making the working efficiency of the device higher.
[0014] 2. By installing the springs in the present invention, the two clamping frames can be pulled, so that the pulled clamping frames can clamp and fix the commutator. Since the commutator can be clamped and fixed, the commutator is not easily offset during detection.

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0023] In the following, only some exemplary embodiments are briefly described. As those skilled in the art can recognize, the described embodiments can be modified in various different ways without departing from the spirit or scope of the present utility model. Therefore, the drawings and the description are considered to be exemplary in nature rather than restrictive.
[0024] The embodiments of the present utility model will be described in detail below with reference to the accompanying drawings.
[0025] As Figures 1-5As shown in the figure, an embodiment of the present utility model provides a commutator missing piece detection device, including: a base 1, on which a fixed frame 2 and a second electric push rod 3 are fixedly installed, and two clamping components 4 are slidably arranged. The clamping component 4 includes two clamping frames 5 and two springs 6 fixedly installed between the clamping frames 5. The output end of the second electric push rod 3 is fixedly installed with a sliding frame 18 slidably arranged with the four clamping frames 5. A first electric push rod 7 is fixedly installed on the fixed frame 2, and the output end of the first electric push rod 7 is fixedly installed with a plurality of detection components 8. The detection component 8 includes a sliding seat 9 and a plurality of detection pieces 10 slidably arranged inside the sliding seat 9. A bolt 11 is threadedly arranged on the sliding seat 9, an extrusion piece 12 is arranged below the bolt 11, and a rubber piece 13 is arranged below the extrusion piece 12.
[0026] In this embodiment, specifically: the base 1 is of an inverted U-shaped structure, and two guiding strips 14 for guiding the two ends of the four clamping frames 5 respectively are fixedly installed on the upper surface of the base 1. An inclined angle is provided on each of the four sides of the four clamping frames 5 where they are close to each other. The installation of the guiding strips 14 can guide the clamping frames 5 during the sliding process, making the sliding process of the clamping frames 5 smoother.
[0027] In this embodiment, specifically: the sliding frame 18 is provided with four pushing protrusions 601 respectively fitting with the eight inclined angles. Two receiving seats 15 are fixedly installed on the base 1. The output end of the second electric push rod 3 penetrates through the base 1. The installation of the receiving seats 15 is for placing the commutator.
[0028] In this embodiment, specifically: both of the two guiding strips 14 are of an L-shaped structure. The two receiving seats 15 are respectively located between the four clamping frames 5. The installation of the receiving seats 15 facilitates the determination of the position for placing the commutator.
[0029] In this embodiment, specifically: the fixed frame 2 is of an inverted U-shaped structure. A plurality of reset pieces 16 corresponding to the plurality of detection components 8 respectively are fixedly installed on the fixed frame 2. The output end of the first electric push rod 7 is fixedly installed with a connecting strip 17, and the plurality of detection components 8 are fixedly installed on the connecting strip 17. When the detection of the commutator is completed, then the first electric push rod 7 that continues to be turned on drives the plurality of detection pieces 10 to slide towards the side close to the reset pieces 16. When the plurality of detection pieces 10 contact the reset pieces 16, the heights of the plurality of detection pieces 10 are reset at this time, which facilitates the next round of detection of the commutator by the plurality of detection pieces 10.
[0030] In this embodiment, specifically: there is a damping fit between multiple detection pieces 10 and the rubber piece 13. The multiple detection pieces 10 are all located below the centering piece 16. When the damping force of the multiple detection pieces 10 decreases, the rotating bolt 11 squeezes the extrusion piece 12 and the rubber piece 13. When the rubber piece 13 is squeezed, the diameter of the rubber piece 13 increases at this time. Then the rubber piece 13 increases the extrusion force on the detection pieces 10, and the damping force of the multiple detection pieces 10 increases at this time.
[0031] When the present utility model is working: when the device needs to detect multiple commutators simultaneously, then multiple commutators are placed between multiple clamping components 4 at this time, and then the first electric push rod 7 is turned on. The turning on of the first electric push rod 7 drives the detection component 8 to slide. Then the detection pieces 10 slide towards the top of the mica sheet of the commutator. When the multiple detection pieces 10 come into contact with the mica, after the detection pieces 10 are hijacked by the mica sheet, the detection pieces 10 no longer continue to slide down. When the mica sheet is missing, the detection pieces 10 continue to slide down. When the detection pieces 10 slide a certain distance, then the first electric push rod 7 is turned on in the reverse direction. After the first electric push rod 7 is turned on, the detection component 8 slides upward. Because a certain mica sheet is missing, the heights of the multiple detection pieces 10 on the corresponding detection component 8 are inconsistent. Then the commutator corresponding to the detection pieces 10 with inconsistent heights is taken down, and it is unqualified.
[0032] Then the bolt 11 is rotated. After the bolt 11 rotates, it squeezes the extrusion piece 12 and the rubber piece 13. When the rubber piece 13 is squeezed, the rubber piece 13 squeezes the multiple detection pieces 10. When the damping force of the detection pieces 10 is small, it can be adjusted by rotating the bolt 11.
[0033] When it is necessary to clamp the commutator, the second electric push rod 3 is turned on at this time. The turning on of the second electric push rod 3 drives the sliding frame 18 to slide downward. After the sliding frame 18 slides, the sliding frame 18 no longer squeezes the clamping frame 5. Then the two clamping frames 5 slide closer to each other under the pulling of the spring 6. During the process that the two springs 6 slide closer to each other, the commutator is clamped and fixed. When it is necessary to take down the commutator, the second electric push rod 3 is turned on in the reverse direction at this time, and the sliding frame 18 pushes the two clamping frames 5 to no longer clamp and fix the commutator.
[0034] The above is only the specific implementation manner of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model can easily think of various changes or substitutions thereof, and these should all be covered within the protection scope of the present utility model. Therefore, the protection scope of the present utility model should be subject to the protection scope of the claims.
