Technical Field

[0001] This utility model relates to the technical field of inter-segment insulation monitoring devices, specifically to commutator processing devices. Background Technology

[0002] Commutators are the core components of DC motors and some AC motors, such as AC commutator motors. They are mainly used to achieve mechanical conversion of current direction and ensure continuous operation of the motor. Usually, after the commutator workpiece is processed, the resistance value between each adjacent commutator segment needs to be detected by an inter-segment insulation monitoring device to avoid short circuits.

[0003] However, the current processing and quality inspection of commutators involves manual inspection after the commutator is machined on a machine tool. This results in the inability to detect processing defects in a timely manner, which affects production efficiency and yield. Therefore, those skilled in the art have provided a commutator processing device to solve the problems mentioned in the background art. Utility Model Content

[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. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-4 In this embodiment of the utility model, the commutator processing device includes a lathe and a commutator inter-segment insulation detection device. The commutator inter-segment insulation detection device includes a mounting bracket 1 installed on the lathe bed, support columns 2 fixed on both sides of the mounting bracket 1, a connecting frame 3 installed on the top of the mounting bracket 1, a stabilizing mechanism 4 provided on the outside of the connecting frame 3, a reinforcing mechanism 5 installed on the outside of the connecting frame 3, an electric push rod 6 fixed on one side of the connecting frame 3, an insulation monitoring mechanism body 7 installed at one end of the output shaft of the electric push rod 6, and a detection contact 8 connected to the bottom of the insulation monitoring mechanism body 7.

[0023] The stabilizing mechanism 4 includes a connecting sleeve 41. A guide slider 42 is slidably connected to the outside of the connecting sleeve 41 via a groove. A movable metal sleeve 43 is fixed to the outside of the guide slider 42. A metal pad 44 is fixed to the outside of the guide slider 42. An mounting block 45 is fixed to the outside of the connecting bracket 3. A limit bracket 46 is mounted on the outside of the mounting block 45. A positioning threaded rod 47 is fixed to the outside of the mounting block 45. A washer 48 is movably sleeved on the outside of the positioning threaded rod 47. A positioning nut 49 is threadedly connected to the outside of the positioning threaded rod 47. The connecting sleeve 41 and the mounting bracket 1 are fixedly connected. The movable metal sleeve 43 is movably sleeved on the outside of the positioning threaded rod 47. A groove is provided inside the limit bracket 46. The size of the groove is adapted to the size of the movable metal sleeve 43.

[0024] In one embodiment of this utility model, the reinforcement mechanism 5 includes a mounting pad 51, a fixed semi-threaded column 52 fixed to the top of the mounting pad 51, a reinforcement pad 53 fixed to the outside of the mounting pad 51, a fixing block 54 mounted on the top of the mounting bracket 1, a fixing rod 55 fixed to the top of the fixing block 54, a limit pad 56 fixed to the outside of the fixing rod 55, a rotating plate 57 connected to the outside of the fixing rod 55 via a bearing, a movable semi-threaded rod 58 mounted on the top of the rotating plate 57, a connecting nut 59 threadedly connected to the outside of the movable semi-threaded rod 58 and the fixed semi-threaded column 52, the mounting pad 51 and the connecting bracket 3 are fixedly connected, and the bottom surface of the rotating plate 57 is in contact with the mounting pad 51.

[0025] The working principle of this utility model is as follows: while machining the commutator on the lathe, the insulation between the commutator segments is simultaneously tested using an insulation detection device. This ensures real-time monitoring of whether the product is qualified during the machining process, avoiding the need for a separate person to test the product in traditional processes, and greatly improving work efficiency. This device is equipped with a stabilizing mechanism 4. After the connecting frame 3 and the mounting bracket 1 are fixedly connected, the corresponding surface of the mounting block 45 on the outer side of the connecting frame 3 fits against the mounting bracket 1. Then, the metal pad 44 is moved to drive the guide slider 42 and the moving metal sleeve 43 to move, allowing the moving metal sleeve 43 to movably engage with the outer side of the positioning threaded rod 47. Subsequently, the washer 48 is movably engaged with the outer side of the positioning threaded rod 47, and the positioning nut 49 is threadedly connected to the positioning threaded rod 47, which conveniently completes the fixation between the moving metal sleeve 43 and the mounting block 45, thereby reinforcing the connection between the connecting frame 3 and the mounting bracket 1. This significantly improves the rigidity of the connection between the connecting frame 3 and the mounting bracket 1, making it less prone to resonance or deformation due to lathe vibration. It maintains the accurate position of the detection contact 8 relative to the device under test, solving the problem of the detection contact 8 shifting due to machine tool vibration. In the initial position, the calibrated detection contact 8 makes good contact with two adjacent switching plates to ensure the contact accuracy of the calibration contact. After processing, a full cycle test is performed again. To ensure that there are no inter-piece short circuits in the processed products, real-time detection can be performed to promptly identify processing defects, improve yield, and increase inspection efficiency. A reinforcement mechanism 5 is provided. After the connecting frame 3 is fixed to the top of the mounting bracket 1, the bottom surface of the mounting pad 51 on the outside of the connecting frame 3 is in contact with the mounting bracket 1. Moving the rotating plate 57 on the outside of the fixing rod 55 allows the corresponding surface of the movable semi-threaded rod 58 on the top of the rotating plate 57 to align with the fixed semi-threaded post 52. After the connecting nut 59 and the fixed semi-threaded post 52 are threadedly connected to the movable semi-threaded rod 58, the mounting pad 51 and the rotating plate 57 are easily fixed, thus providing auxiliary reinforcement to the outside of the connecting frame 3. This reinforcement design makes the connecting frame 3 more resistant to accidental collisions. The insulation monitoring mechanism body 7 is driven by an electric push rod 6. During the commutator rotation processing, the detection contact 8 contacts adjacent commutator segments in real time, continuously detecting the inter-piece resistance value to ensure that there are no inter-piece short circuits in the processed products, achieving dynamic follow-up monitoring.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
