Description

Technical Field

[0001] This utility model relates to the field of motor testing technology, and in particular to a rotor performance testing device. Background Technology

[0002] In the construction of a motor rotor, there is a close connection between the windings and the commutator segments. This connection is the key link in the rotor's conversion of electrical energy into mechanical energy. Before assembling the rotor with the motor housing, a crucial task is to test the conductivity of the windings. This is done by having a test probe contact the commutator segments.

[0003] It is worth noting that a rotor typically has multiple sets of commutator segments, which are numerous and closely arranged. In such cases, manually testing the winding continuity requires operators to examine each set of commutator segments individually, a time-consuming and inefficient process. Furthermore, manual testing is prone to omissions and duplicates. Therefore, manually testing winding continuity is neither efficient nor can it guarantee the accuracy of the results. Consequently, it is necessary to develop a rotor performance testing device to address these issues. Utility Model Content

The proximity switch is fixed on the fixed base and corresponds to the clearance hole.

[0007] Further description of the present invention: The positioning platform also includes an adjustment seat and a V-shaped rod. The adjustment seat is fixed above the platform. Two sets of adjustment seats are provided and correspond to the left and right sides of the first V-shaped groove respectively. The left and right ends of the V-shaped rod are fixed on the two sets of adjustment seats respectively and are adjustable in the vertical direction. The V-shaped rod corresponds to the front end of the first V-shaped groove. The V-shaped rod is provided with a second V-shaped groove and a support groove. The second V-shaped groove opens upward and the support groove is connected to the bottom of the second V-shaped groove.

[0008] Further description of the present invention: The Y-axis drive assembly includes a Y-axis cylinder, a Y-axis slide, a connecting block, and a slider. The Y-axis cylinder and the Y-axis slide are both fixed above the worktable. The left and right ends of the connecting block are respectively fixed to the power output end of the Y-axis cylinder and the movable base. The slider is fixed below the movable base and is slidably connected to the Y-axis slide.

[0009] Further description of this utility model: The detection assembly includes a mounting bracket, a limiting ring, a mounting disc, a drive turntable, a Y-axis slide bar, a detection probe, an X-axis drive assembly, a U-shaped block, and a drive rod. The mounting bracket is fixed on the worktable. The limiting ring and the mounting disc are sequentially fixed on the front side of the mounting bracket. The X-axis drive assembly is fixed on the rear side of the mounting bracket. The drive turntable is rotatably mounted inside the limiting ring. The mounting disc has a shaft insertion hole in the center. The mounting disc has multiple sets of radially arranged sliding grooves. The drive turntable has grooves that intersect with the sliding grooves. The first arc-shaped groove corresponds to the first arc-shaped groove. One end of the first arc-shaped groove extends towards the side of the rotating shaft insertion hole. The middle part of the Y-axis slide rod is slidably connected to the slide groove. The rear end of the Y-axis slide rod is slidably connected to the first arc-shaped groove. The detection probe is fixed to the front end of the Y-axis slide rod. The U-shaped block is fixed to the power output end of the X-axis drive assembly. The upper end of the U-shaped block is provided with a U-shaped groove.

[0011] The beneficial effects of this invention are as follows: The rotor is placed on the positioning platform manually or by a robotic arm. The iron core of the rotor is placed in the first V-groove on the platform, with the outer end face of the iron core corresponding to the top of the proximity switch. The proximity switch can sense the rotor. There are grooves between the windings on the iron core. The rotor is rotated by the rotation drive assembly. During rotation, when the grooves align with the top of the proximity switch, the proximity switch can no longer sense the rotor. At this point, the rotation drive assembly stops, ensuring the rotor iron core is positioned in a specific location. Next, the Y-axis drive assembly drives the movable base backward, moving the rotor to the detection assembly. The detection assembly contacts the commutator segments on the rotor and detects their continuity. Because the iron core is positioned at a specific angle in the first V-groove, the detection assembly can accurately contact each set of commutator segments and detect their continuity. The advantages of this design are: it can automatically and quickly detect the continuity of the motor rotor windings, with high detection efficiency and no missed or repeated measurements, thus improving detection accuracy.

[0021] The present invention will be further described below with reference to the accompanying drawings:

[0022] like Figures 1 to 5 As shown, a rotor performance testing device includes a worktable 1, a Y-axis drive assembly 2, a testing assembly 3, a movable base 4, a positioning platform 5, and a rotation drive assembly 6. The Y-axis drive assembly 2 and the testing assembly 3 are respectively fixed on the front and rear sides above the worktable 1. The movable base 4 is fixed to the power output end of the Y-axis drive assembly 2. The positioning platform 5 and the rotation drive assembly 6 are both fixed on the movable base 4. The positioning platform 5 includes a fixed base 51, a platform 52, and a proximity switch 53. The fixed base 51 is fixed above the worktable 1, and the platform 52 is fixed above the fixed base 51. The platform 52 corresponds between the testing assembly 3 and the rotation drive assembly 6. The platform 52 is provided with a first V-groove 521 and a clearance hole 522. The first V-groove 521 opens upward, and the clearance hole 522 communicates with the bottom of the first V-groove 521. The proximity switch 53 is fixed on the fixed base 51 and corresponds to the clearance hole 522.

[0023] The rotor is placed on the positioning platform 5 manually or by a robotic arm. The iron core of the rotor is placed in the first V-groove 521 on the carrier 52, with the outer end face of the iron core corresponding to the top of the proximity switch 53. The proximity switch 53 can sense the rotor. There are grooves between the windings on the iron core. The rotor is rotated by the rotation drive assembly 6. During the rotation, when the grooves correspond to the top of the proximity switch 53, the proximity switch 53 can no longer sense the rotor. At this time, the rotation drive assembly 6 stops running, thus ensuring that the rotor iron core is placed in a specific position. Then, the Y-axis drive assembly 2 drives the movable base 4 to move backward, thereby moving the rotor to the detection assembly 3. The detection assembly 3 contacts the commutator segments on the rotor and detects the continuity performance. Since the iron core is positioned at a specific angle on the first V-groove 521, the detection assembly 3 can accurately contact each set of commutator segments and detect the continuity performance. The advantage of this design is that it can automatically and quickly detect the continuity performance of the motor rotor windings, with high detection efficiency and no missed or repeated tests, thus improving the accuracy of the detection.

[0024] The positioning platform 5 also includes an adjustment seat 54 and a V-shaped rod 55. The adjustment seat 54 is fixed above the platform 52. Two sets of adjustment seats 54 are provided and correspond to the left and right sides of the first V-shaped groove 521 respectively. The left and right ends of the V-shaped rod 55 are fixed on the two sets of adjustment seats 54 respectively and the position is adjustable in the vertical direction. The V-shaped rod 55 corresponds to the front end of the first V-shaped groove 521. The V-shaped rod 55 is provided with a second V-shaped groove 551 and a support groove 552. The second V-shaped groove 551 opens upward and the support groove 552 is connected to the bottom of the second V-shaped groove 551.

[0025] After the rotor is placed on the positioning platform 5, the iron core is placed in the first V-groove 521, and the rear end of the rotor shaft is placed in the support groove 552. During the process of the shaft entering the support groove 552, the second V-groove 551 plays a guiding role. During the process of the rotation drive assembly 6 clamping and rotating the rotor shaft, the rotor can be prevented from shifting in the left and right directions due to the restriction of the support groove 552.

[0026] The Y-axis drive assembly 2 includes a Y-axis cylinder 21, a Y-axis slide 22, a connecting block 23, and a slider 24. The Y-axis cylinder 21 and the Y-axis slide 22 are both fixed above the worktable 1. The left and right ends of the connecting block 23 are respectively fixed to the power output end of the Y-axis cylinder 21 and the movable base 4. The slider 24 is fixed below the movable base 4 and is slidably connected to the Y-axis slide 22.

[0027] Y-axis cylinder 21 drives movable base 4 to move back and forth through connecting block 23, and movable base 4 slides on Y-axis slide table 22 through slider 24.

[0028] The detection component 3 includes a mounting bracket 31, a limiting ring 32, a mounting disk 33, a drive turntable 34, a Y-axis slide bar 35, a detection probe 36, an X-axis drive assembly 37, a U-shaped block 38, and a drive rod 39. The mounting bracket 31 is fixed on the worktable 1. The limiting ring 32 and the mounting disk 33 are sequentially fixed to the front side of the mounting bracket 31. The X-axis drive assembly 37 is fixed to the rear side of the mounting bracket 31. The drive turntable 34 is rotatably mounted inside the limiting ring 32. The mounting disk 33 has a shaft insertion hole 331 in the middle. The mounting disk 33 has multiple sets of radially arranged sliding grooves 332. The drive turntable 34 has grooves corresponding to the sliding grooves 332 one by one. The first arc-shaped groove 341 extends one end toward the rotating shaft insertion hole 331. The middle part of the Y-axis slide rod 35 is slidably connected to the slide groove 332, and the rear end of the Y-axis slide rod 35 is slidably connected to the first arc-shaped groove 341. The detection probe 36 is fixed to the front end of the Y-axis slide rod 35. The U-shaped block 38 is fixed to the power output end of the X-axis drive assembly 37. The upper end of the U-shaped block 38 is provided with a U-shaped groove 381. The mounting bracket 31 is provided with a second arc-shaped groove 311. The front end of the drive rod 39 is fixed to the rear end face of the drive turntable 34. The middle part of the drive rod 39 is slidably connected to the second arc-shaped groove 311, and the rear end of the drive rod 39 is slidably connected to the U-shaped groove 381.

[0029] After the rotor moves backward and is inserted into the shaft insertion hole 331, the X-axis drive assembly 37 drives the U-shaped block 38 to move, thereby moving the drive rod 39. The rear end of the drive rod 39 moves vertically relative to the U-shaped groove 381, while the front end of the drive rod 39 causes the drive turntable 34 to rotate within the limiting ring 32. The rotation of the drive turntable 34 drives the Y-axis slide rod 35 to slide along the slide groove 332 through the first arc groove 341. When the Y-axis slide rod 35 moves toward the shaft insertion hole 331, it drives the detection probe 36 to move toward the rotor, thereby making the detection end contact the commutator segment. That is, the X-axis drive assembly 37 can simultaneously drive each group of detection probes 36 to move toward the center of the mounting disk 33 and make each group of detection probes 36 contact each group of commutator segments, thereby performing a continuity performance test simultaneously.

[0030] The rotation drive assembly 6 includes a mounting base 61, a rotary motor 62, a rotating bracket 63, a rotating block 64, a clamping cylinder 65, and grippers 66. The mounting base 61 is fixed above the movable base 4. The rotary motor 62 and the rotating bracket 63 are respectively fixed on the front and rear sides above the mounting base 61. The rotating block 64 is rotatably mounted on the rotating bracket 63 and fixedly connected to the power output end of the rotary motor 62. The clamping cylinder 65 is fixed to the rear end of the rotating block 64. Two sets of grippers 66 are provided and are respectively fixed to the two sets of power output ends at the rear end of the clamping cylinder 65.

[0031] The clamping cylinder 65 drives two sets of grippers 66 to clamp the rear end of the rotor shaft, and the rotating block 64 is driven to rotate on the rotating bracket 63 by the rotary motor 62, thereby driving the clamping cylinder 65 to rotate and causing the rotor to rotate at a certain angle.
