Description

Technical Field

[0001] This utility model relates to the field of motor manufacturing technology, specifically a positioning tooling for motor manufacturing. Background Technology

[0002] Electric motors, as core power devices in modern industry, come in many types, mainly including DC motors, AC asynchronous motors, permanent magnet synchronous motors, and stepper motors. Among them, permanent magnet synchronous motors and some high-efficiency brushless DC motors are widely used in new energy vehicles, industrial automation, and precision equipment due to their high power density and energy-saving characteristics. These motors typically require the embedding of multiple arc-shaped magnet tiles to form a stable magnetic field. The installation position, angle, and gap accuracy of the magnet tiles directly affect the electromagnetic symmetry, torque output efficiency, and noise and vibration levels of the motor.

[0003] Currently, the installation of motor tiles is mostly done manually. This traditional method has many drawbacks. First, manual operation makes rapid positioning difficult; workers need to rely on their experience and eyesight to determine the tile's position, a time-consuming process that slows down installation and significantly impacts production efficiency. Second, manual installation is prone to errors. Since human visual judgment and manual operation cannot achieve absolute precision, deviations in tile placement can lead to uneven magnetic field distribution within the motor, affecting performance such as reduced efficiency and increased operating noise. Furthermore, manual installation demands a high level of skill and concentration from workers; prolonged repetitive operations can cause fatigue, further increasing the likelihood of installation errors.

[0004] Based on this, a positioning fixture for motor production is now provided, which can eliminate the drawbacks of existing devices. Utility Model Content

[0024] In one embodiment, such as Figures 1-6 As shown, a positioning fixture for motor production includes mounting rods 11 and positioning seats 41. Each of the two mounting rods 11 has a mounting seat at one end, and the two mounting seats are symmetrically arranged on a first internal spline shaft 12. The first internal spline shaft 12 is rotatably mounted at the output end of a first electric cylinder 13. The first electric cylinder 13 is installed in a mounting hole at the upper end of a top plate 14. The top plate 14 is fixedly mounted on the upper end of a worktable 15. Each mounting rod 11 has a rotatable mounting rod 18 at one end, and the mounting rod 18 has a plurality of positioning positions arranged in an array. A fixed rod 19 is provided, and a sliding tube 20 is sleeved on each fixed rod 19. A loading frame 21 is fixed at one end of each sliding tube 20. The first fixed rod 19 is provided with a pushing mechanism to facilitate the discharge of tiles inside the loading frame 21. The positioning seat 41 is fixed on the upper end of the workbench 15. The bottom end of the top plate 14 is provided with a correction mechanism for correcting the installation angle of the loading frame 21. The correction mechanism aligns the loading frame 21 with the installation position inside the motor housing 40. The pushing mechanism facilitates the discharge of tiles inside the loading frame 21.

[0025] The first internal spline shaft 12 is internally fitted with a first external spline shaft 16, which is fixedly mounted on one end of a fixed shaft. The fixed shaft is rotatably mounted in the mounting hole at the upper end of the worktable 15. The fixed shaft is fixedly connected to the output end of a motor 17, which is mounted at the bottom of the worktable 15. The motor 17 is electrically connected to the control component 45. In use, when it is necessary to install the tile, the output end of the first electric cylinder 13 drives the first internal spline shaft 12 to move. The first internal spline shaft 12 drives several loading racks 21 on the two mounting supports 11 to move downward. The operator places the tile inside the loading rack 21 near the control component 45. Then, the output end of the first electric cylinder 13 drives the first internal spline shaft 12 to rise. Then, the motor 17 drives the first internal spline shaft 12 to rotate 180 degrees, so that the tile moves above the positioning seat 41. Then, the operator places the motor housing 40 on the upper end of the positioning seat 41.

[0026] The calibration mechanism includes a calibration wheel 34 and a calibration friction plate 35. A second external spline shaft 32 is fixedly mounted on one end of each mounting rod 18. A second internal spline shaft 33 is fitted onto each of the second external spline shafts 32. A calibration wheel 34 is fixedly mounted on one end of each of the second internal spline shafts 33. The calibration wheel 34 has a notch, and symmetrical mounting grooves are provided at the notch. Rotating rollers are rotatably mounted in each mounting groove. A calibration friction plate 35 is fitted above the positioning seat 41 at a position corresponding to the calibration wheel 34. One end of the calibration friction plate 35 is inclined. Several guide rods are fixedly mounted on one side of the calibration friction plate 35. The guide rods are slidably mounted in sliding holes on one side of the fixed tube 37. Several fourth return springs 36 are provided between one side of the calibration friction plate 35 and one side of the fixed tube 37. The several fourth return springs 36 are coaxially mounted with the several guide rods. The calibration friction plate 35... Both the 5 and the fixed tube 37 are fixedly installed on one side of the mounting plate. The mounting plate is symmetrically provided with support rods 39 on one side. The mounting plate is fixedly installed on the support frame. The support frame is fixedly installed at the output end of the second electric cylinder 38. The second electric cylinder 38 is fixedly installed on the upper end of the top plate 14. In use, when the loading frame 21 moves above the positioning seat 41, the control component 45 controls the second electric cylinder 38 to start. The output end of the second electric cylinder 38 drives the correction friction plate 35 and the support rod 39 to move through the support frame. Since one end of the correction friction plate 35 is inclined, one side of the correction friction plate 35 is in close friction with the outer side of the correction wheel 34, so that the correction friction plate 35 slides along the axis of the guide slide rod. When one side of the correction friction plate 35 is in close contact with the notch on the correction wheel 34, the position of the correction wheel 34 is corrected under the action of several fourth return springs 36, and several loading frames 21 are aligned with the mounting groove inside the motor housing 40.

A linkage plate 30 is fixedly mounted on one end of the sliding rod 29. A connection is provided between the upper end of the linkage plate 30 and the interior of the mounting rotating rod 18. The third return spring 31, the mounting rod 18 is slidably provided with a limiting slide plate 25, the upper end of the sliding tube 20 is fixedly provided with a fixing plate, the fixing plate is slidably provided in the guide groove at the upper end of the limiting slide plate 25, the fixing plate is provided with a first return spring 22 between one side of the fixing plate and the mounting rod 18, the fixing plate is fixedly provided with a guide block 23 at one end of the fixing plate, the guide block 23 has a right-angled triangular cross section, the inclined surface of the guide block 23 is closely attached to the top frame 24, the top frame 24 is fixedly provided at the upper end of the limiting slide plate 25, and the upper end of the worktable 15 is provided with a drive assembly for starting the movement of the limiting slide plate 25.

[0028] The drive assembly includes a limiting slide plate 25 with symmetrically arranged extension plates 46. The upper end of the worktable 15 is symmetrically provided with a third electric cylinder 44 corresponding to the position of the positioning seat 41. The output end of the third electric cylinder 44 is fixedly provided with a support plate 43. The support plate 43 is aligned with the extension plate 46. In use, when it is necessary to install tiles, the loading frame 21 is moved into the motor housing 40. Then, the output end of the third electric cylinder 44 drives the support plate 43 to move. The support plate 43 and the extension plate 46 are in close contact, causing the limiting slide plate 25 to slide. The limiting slide plate 25 cooperates with the guide block 23 through the top frame 24, causing the sliding tube 20 to slide. The sliding tube 20 drives the loading frame 21 to slide. At the same time, the limiting slide plate 25 drives the sliding rod 29 to slide through the linkage plate 30. The sliding rod 29 drives the push rod 26 to slide through the connecting rod 28. The push rod 26 pushes out the tiles inside the loading frame 21, thereby installing the tiles into the mounting slot inside the motor housing 40.

[0029] The positioning base 41 is symmetrically provided with positioning plates 42 at its upper end. In use, the positioning plates 42 limit the support feet on the motor housing 40 during installation, thereby facilitating the positioning and installation of the motor housing 40.

[0030] The above embodiment discloses a positioning fixture for motor production. When a tile needs to be installed, the output of the first electric cylinder 13 drives the first internal spline shaft 12 to move. The first internal spline shaft 12 drives several loading racks 21 on the two mounting supports 11 to move downwards. The operator places the tile inside the loading rack 21 near the control component 45. Then, the output of the first electric cylinder 13 drives the first internal spline shaft 12 to rise. Subsequently, the motor 17 drives the first internal spline shaft 12 to rotate 180 degrees, causing the tile to move above the positioning seat 41. The operator then places the motor housing 40 on top of the positioning seat 41. After the loading rack 21 moves above the positioning seat 41, the control component 45 controls the second electric cylinder 38 to start. The output of the second electric cylinder 38 drives the correction friction plate 35 and the support rod 39 to move via the support frame. Since one end of the correction friction plate 35 is inclined, one side of the correction friction plate 35 is aligned with the correction wheel 34. The outer friction is in close contact, causing the correction friction plate 35 to slide along the axis of the guide slide rod. When one side of the correction friction plate 35 is in close contact with the notch on the correction wheel 34, the position of the correction wheel 34 is corrected under the action of several fourth return springs 36. Several loading racks 21 are aligned with the mounting slots inside the motor housing 40. When it is necessary to install the tile, the loading rack 21 is moved into the motor housing 40. Then, the output end of the third electric cylinder 44 drives the support plate 43 to move. The support plate 43 and the extension plate 46 are in close contact, causing the limiting slide plate 25 to slide. The limiting slide plate 25 cooperates with the guide block 23 through the top frame 24, causing the sliding tube 20 to slide. The sliding tube 20 causes the loading rack 21 to slide. At the same time, the limiting slide plate 25 drives the sliding rod 29 to slide through the linkage plate 30. The sliding rod 29 drives the push rod 26 to slide through the connecting rod 28. The push rod 26 pushes out the tile inside the loading rack 21, thereby installing the tile into the mounting slot inside the motor housing 40.
