Description

Technical Field

[0001] This utility model relates to the field of magnetic ring testing technology, and more specifically to a tooling for testing the magnetic properties of magnetic rings. Background Technology

[0002] During the production of motor magnetic rings, the surface magnetic field of the rings needs to be tested. Surface magnetic field, also known as surface field or surface magnetic field, refers to the magnetic induction intensity at a point on the surface of a magnet. When the size of the magnet is fixed, the performance of the magnet can be judged and compared by measuring the surface magnetic field.

[0003] Existing testing devices typically involve manually holding a magnetic ring and then using a gaussmeter probe for testing. However, during the manual rotation of the magnetic ring, hand tremors can easily cause the magnetic ring to touch the probe, resulting in damage to the probe. Furthermore, manual operation increases the workload for workers. Utility Model Content

[0004] The purpose of this invention is to provide a tooling for magnetic ring detection, in order to solve the problem mentioned in the background art that the magnetic ring is easily damaged by hand tremors during the manual rotation detection of the magnetic ring, which can cause the magnetic ring to touch the probe.

[0005] To achieve the above objectives, this utility model provides a tooling for magnetic ring testing, including a base, on which a first dual-axis cylinder is fixedly mounted. A support platform is provided on the top of the first dual-axis cylinder, and a clamping mechanism for clamping and limiting the magnetic ring to be tested is provided on the support platform. An adjustment mechanism for driving the magnetic ring to rotate is provided on the clamping mechanism. An L-shaped plate is fixedly mounted on the base on one side of the first dual-axis cylinder, and a testing mechanism is provided on the upper end of the L-shaped plate.

[0006] By adopting the above scheme, the output end of the motor drives the drive roller to rotate, and the drive roller contacts the magnetic ring, thereby driving the magnetic ring to rotate. This makes it easy to adjust the rotation of the magnetic ring, and the positioning effect of the arc groove on the magnetic ring prevents the magnetic ring from shifting or misaligning.

[0007] As a further improvement to this technical solution, the clamping mechanism includes a screw, a groove is provided on the surface of the support platform, the screw is rotatably disposed in the groove, one end of the screw passes through the support platform and is fixedly provided with a handwheel, two threaded sleeves are threadedly connected to the screw, and a clamping block is fixedly provided on the top of each of the two threaded sleeves, and an arc-shaped groove for clamping the magnetic ring is provided on the opposite side of each of the two clamping blocks.

[0008] As a further improvement to this technical solution, the adjustment mechanism includes a motor, which is fixedly mounted on the top of the clamping block. A first cavity is provided inside the clamping block, and a drive roller for contacting the magnetic ring is rotatably mounted inside the first cavity. The output end of the motor passes through the clamping block and is fixedly connected to the drive roller.

[0009] As a further improvement to this technical solution, a fixing block is fixedly installed on both sides of the first dual-axis cylinder on the base. The output end of the first dual-axis cylinder is fixedly connected to one fixing block, and a limiting post is provided at the bottom of the first dual-axis cylinder to be fixed to another fixing block.

[0010] By adopting the above scheme, the positioning effect of the fixed block drives the first dual-axis cylinder to move left and right, and the first dual-axis cylinder drives the support platform to move left and right for adjustment.

[0011] As a further improvement to this technical solution, a limiting block is fixedly provided at the bottom of the screw sleeve, and a limiting groove adapted to the limiting block is provided at the bottom of the support platform.

[0012] By adopting the above scheme, the screw sleeve is limited by the limiting block, so that the screw sleeve will not rotate with the screw.

[0013] As a further improvement to this technical solution, a plurality of positioning columns are fixedly installed at the bottom of the support platform, and the side wall of the first dual-axis cylinder is provided with positioning holes that are adapted to the plurality of positioning columns.

[0014] By adopting the above scheme, the first dual-axis cylinder is positioned and installed using multiple positioning pins.

[0015] As a further improvement to this technical solution, the clamping block has two second cavities inside, and the clamping block is rotatably equipped with support rollers in both second cavities.

[0016] By adopting the above scheme, the magnetic ring is supported by the support roller, which reduces the resistance when the magnetic ring rotates and facilitates the adjustment of the magnetic ring's rotation.

[0017] As a further improvement to this technical solution, the detection mechanism includes a second dual-axis cylinder, which is fixedly mounted on the side wall of the L-shaped plate. A support plate is fixedly mounted on the output end of the second dual-axis cylinder. An mounting plate is mounted on one side of the support plate. A detection frame is mounted between the support plate and the mounting plate. A gaussmeter probe is mounted at the bottom of the detection frame.

[0018] By adopting the above scheme, the output end of the second dual-axis cylinder drives the support plate and the mounting plate to move downwards. The support plate and the mounting plate drive the detection frame and the gaussmeter probe to move downwards, and the up and down movement of the gaussmeter probe is very stable.

[0019] As a further improvement to this technical solution, L-shaped blocks are fixedly arranged on both sides of the L-shaped plate, and the second dual-axis cylinder is fixedly connected to the two L-shaped blocks.

[0020] By adopting the above scheme, the second dual-shaft cylinder is fixedly installed using two L-shaped blocks, thereby improving the stability of the second dual-shaft cylinder.

[0021] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0022] 1. This fixture for magnetic ring meter testing incorporates a testing mechanism. Its second dual-axis cylinder can move the testing frame and gaussmeter probe up or down, facilitating probe position adjustment. The gaussmeter probe moves very stably up and down, and throughout the process, it does not contact the magnetic ring. This effectively avoids the problem of traditional manual testing methods where hand tremors can cause the magnetic ring to touch the probe, leading to probe damage. The output end of the first dual-axis cylinder extends and retracts, thereby moving the magnetic ring left and right for adjustment, making magnetic ring position adjustment very convenient.

[0023] 2. The fixture for magnetic ring detection is equipped with an adjustment mechanism. The motor output drives the drive roller to rotate, and the drive roller contacts the magnetic ring, thereby driving the magnetic ring to rotate. This facilitates the rotation adjustment of the magnetic ring. Furthermore, due to the positioning effect of the arc groove on the magnetic ring, the magnetic ring will not be offset or misaligned. The support roller supports the magnetic ring, reducing the resistance when the magnetic ring rotates and facilitating the rotation adjustment of the magnetic ring. Attached Figure Description

[0034] Please see Figures 1-5 As shown, this utility model provides a tooling for magnetic detection of a magnetic ring meter, including a base 1, on which a first dual-axis cylinder 2 is fixedly mounted. A support platform 3 is provided on the top of the first dual-axis cylinder 2, and multiple positioning posts 9 are fixedly mounted on the bottom of the support platform 3. Positioning holes adapted to the multiple positioning posts 9 are opened on the side wall of the first dual-axis cylinder 2. The first dual-axis cylinder 2 is positioned and installed by the multiple positioning posts 9. Fixing blocks 8 are fixedly mounted on both sides of the first dual-axis cylinder 2 on the base 1. The output end of the first dual-axis cylinder 2 is fixedly connected to one fixing block 8. A limiting post fixed to another fixing block 8 is provided at the bottom of the first dual-axis cylinder 2. The output end of the first dual-axis cylinder 2 extends and retracts. Through the positioning action of the fixing blocks 8, the first dual-axis cylinder 2 is driven to move left and right. The first dual-axis cylinder 2 drives the support platform 3 to move left and right for adjustment.

[0035] A clamping mechanism 4 is provided on the support platform 3 for clamping and limiting the magnetic ring to be tested. The support platform 3 is used to place the magnetic ring to be tested, and the clamping mechanism 4 positions and clamps the magnetic ring. The clamping mechanism 4 includes a screw 41. A groove is opened on the surface of the support platform 3, and the screw 41 is rotatably disposed in the groove. The screw 41 is provided with two sections of threads with opposite directions. One end of the screw 41 passes through the support platform 3 and is fixedly provided with a handwheel 42. Two threaded sleeves 43 are threadedly connected to the screw 41. Each of the two threaded sleeves 43 is fixedly provided with a clamping block 44 on its top. Each of the blocks 44 has an arc-shaped groove 45 for clamping the magnetic ring on one side. The handwheel 42 is turned manually to drive the screw 41 to rotate, so that the two screw sleeves 43 move towards each other along the screw 41. The two screw sleeves 43 drive the two clamping blocks 44 to move towards each other, so that the arc-shaped grooves 45 of the two clamping blocks 44 position the magnetic ring. The bottom of the screw sleeve 43 is fixedly provided with a limit block 46. The support platform 3 is located at the bottom of the groove and has a limit groove that matches the limit block 46. The limit block 46 limits the screw sleeve 43 so that the screw sleeve 43 will not rotate with the screw 41.

[0036] The clamping block 44 is equipped with an adjustment mechanism 5 for driving the magnetic ring to rotate. The adjustment mechanism 5 includes a motor 51, which is fixedly mounted on the top of the clamping block 44. A first cavity is opened inside the clamping block 44. A drive roller 52 for contacting the magnetic ring is rotatably mounted inside the clamping block 44 in the first cavity. The output end of the motor 51 passes through the clamping block 44 and is fixedly connected to the drive roller 52. When the magnetic ring needs to be rotated and adjusted, the output end of the motor 51 drives the drive roller 52 to rotate. The drive roller 52 contacts the magnetic ring and drives the magnetic ring to rotate, which facilitates the rotation adjustment of the magnetic ring. Due to the positioning effect of the arc groove 45 on the magnetic ring, the magnetic ring will not be offset or misaligned. Two second cavities are opened inside the clamping block 44. A support roller 53 is rotatably mounted in each of the two second cavities. The support roller 53 supports the magnetic ring, reducing the resistance when the magnetic ring rotates and facilitating the rotation adjustment of the magnetic ring.

[0037] Please see Figure 1 and Figure 6As shown, an L-shaped plate 6 is fixedly installed on the base 1 on one side of the first dual-axis cylinder 2. A detection mechanism 7 is installed on the upper end of the L-shaped plate 6. The detection mechanism 7 includes a second dual-axis cylinder 71, which is fixedly installed on the side wall of the L-shaped plate 6. L-shaped blocks 72 are fixedly installed on both sides of the L-shaped plate 6. The second dual-axis cylinder 71 is fixedly connected to the two L-shaped blocks 72, which fix the second dual-axis cylinder 71 and improve its stability. A support plate 73 is fixedly installed at the output end of the second dual-axis cylinder 71. A mounting plate 74 is installed on one side of the support plate 73. A detection frame 75 is installed between the support plate 73 and the mounting plate 74. Both the support plate 73 and the mounting plate 74 have through slots for the detection frame 75 to pass through. A detection frame 75 is installed on the top of the detection frame 75. The test frame 75 is equipped with a gaussmeter probe 76 at its bottom. The output end of the second dual-axis cylinder 71 drives the support plate 73 and the mounting plate 74 to move downwards. The support plate 73 and the mounting plate 74 drive the test frame 75 and the gaussmeter probe 76 to move downwards, bringing the gaussmeter probe 76 close to the magnetic ring for testing. Protective plates 78 are fixedly installed on both sides of the bottom end of the gaussmeter probe 76. The surfaces of the two protective plates 78 are grooved to protect the bottom end of the gaussmeter probe 76 and prevent direct contact with the magnetic ring. Bolts 77 are installed through the outer wall of the mounting plate 74. The mounting plate 74 is connected and fixed to the support plate 73 by the bolts 77. The mounting plate 74 can be opened by removing the bolts 77 to facilitate the installation and removal of the gaussmeter probe 76.

[0038] The specific working principle of this utility model is as follows: The magnetic ring to be tested is placed on the support platform 3. The handwheel 42 is rotated to drive the screw 41 to rotate, so that the two screw sleeves 43 move towards each other along the screw 41. The two screw sleeves 43 drive the two clamping blocks 44 to move towards each other, so that the arc grooves 45 of the two clamping blocks 44 position the magnetic ring. The output end of the second dual-axis cylinder 71 drives the support plate 73 and the mounting plate 74 to move downward. The support plate 73 and the mounting plate 74 drive the detection frame 75 and the gaussmeter probe 76 to move downward, so that the gaussmeter probe 76 is close to the magnetic ring for detection. When the magnetic ring needs to be rotated and adjusted, the output end of the motor 51 drives the drive roller 52 to rotate. The drive roller 52 abuts against the magnetic ring and drives the magnetic ring to rotate, which facilitates the rotation adjustment of the magnetic ring. Due to the positioning effect of the arc groove 45 on the magnetic ring, the magnetic ring will not be offset or misaligned. The support roller 53 supports the magnetic ring, reducing the resistance when the magnetic ring rotates, which facilitates the rotation adjustment of the magnetic ring, and thus allows for comprehensive detection of the magnetic ring.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
