When the test results show that the torque fails to meet the preset standard, due to the lack of an effective automatic adjustment mechanism, the permanent magnet brake usually needs to be unloaded and readjusted. This adjustment method is not only inefficient, but the repeated loading and unloading of the permanent magnet brake can easily lead to increased measurement errors and reduced product quality.

[0012] Optionally, a connecting shaft is further included, one end of which is transmission-connected to the driving member, and the other end of which is connected to the brake rotor.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] The permanent magnet brake detection device provided by the utility model includes a base plate, a fixing part, a driving part and a torque sensor, wherein the base plate has a mounting surface, the fixing part is slidably mounted on the mounting surface, the brake stator is detachably mounted on the fixing part, the brake rotor is rotationally connected to the brake stator, the driving part is transmission-connected to the brake rotor to drive the brake rotor to rotate, the fixing part slides to adjust the gap between the brake stator and the brake rotor, and the torque sensor is installed between the brake rotor and the driver to measure the torque when the driving part drives the brake rotor.

[0015] Through the above structure, during the detection process of the permanent magnet brake detection device provided by the utility model, first, the brake stator of the permanent magnet brake is fixed by the fixing part, the permanent magnet brake is energized, and then a feeler gauge matching the required gap size is placed at the expected gap position between the brake stator and the brake rotor. Subsequently, the fixing part is moved so that the fixing part moves in the direction close to the driving part.

The electromagnetic coil of the permanent magnet brake is then de-energized, so that the brake stator and brake rotor are tightly attracted due to the magnetic force. The servo motor is then started to drive the rotor to rotate. At this time, since the brake stator is fixed, relative displacement will occur between the brake stator and the brake rotor, generating friction. The torque sensor will measure the torque value in real time. If the measured torque does not meet the preset requirement, the brake rotor is continued to rotate and rub against the brake stator, thereby gradually increasing the torque value until the contact rotation friction between the brake rotor and the brake stator reaches the preset torque. Therefore, the permanent magnet brake detection device can not only measure the torque value, but also, based on the measurement results, drive the servo motor to drive the brake rotor and the brake stator to gradually reach the preset torque through contact rotation friction, thus reducing the multiple assembly and disassembly of the permanent magnet brake and reducing product quality, thereby improving detection efficiency.

[0026] Example

[0027] The utility model provides a permanent magnet brake detection device, which is used to solve the technical problem of inconvenience in adjusting a permanent magnet brake whose torque fails to meet a preset standard during detection. The permanent magnet brake detection device includes a base plate 1, a fixing member 2, a torque sensor 4, and a driving member 3, wherein:

[0028] The base plate 1 has a mounting surface 101 . The base plate 1 can be made of metal material to ensure stability during the detection process. The mounting surface 101 is flat to facilitate the installation of other components.

[0029] The fixing part 2 is slidably mounted on the base plate 1. The fixing part 2 can be a chuck to flexibly adapt to the stators of the permanent magnetic brake 14 of different specifications and models. The fixing part 2 can also be replaced by a flat clamp or other special clamps to meet the clamping requirements of the brake stators 141 of different shapes and sizes; the brake stator 141 of the permanent magnetic brake 14 is clamped on the fixing part 2, and the brake rotor 142 is rotatably connected to the brake stator 141 to ensure that it can rotate freely or be stopped by the electromagnetic force during the detection process. The brake rotor 142 and the brake stator 141 are connected. The gap is adjusted to the optimal working range to ensure the best performance of the braking effect; during the detection process of the permanent magnet brake 14, first ensure that the electromagnetic coil is in the unpowered state. At this time, the brake stator 141 does not generate a magnetic field or the magnetic field is extremely weak, and the brake rotor can rotate freely relative to the brake stator 141. Subsequently, the electromagnetic coil is energized, and the stator quickly generates a strong magnetic field. This magnetic field attracts the rotor through magnetic force, generates a braking torque, and gradually decelerates the rotor. Observe and record the voltage, torque and other parameters of the permanent magnet brake 14 to detect the permanent magnet brake 14.

[0030] The driving member 3 is connected to the brake stator 141 in a transmission manner. Specifically, the driving member 3 in this embodiment is a servo motor. After the servo motor is decelerated by the reducer, its output shaft is connected to the brake rotor 142 through a coupling, and the brake rotor 142 is driven to rotate by the servo motor; when testing the permanent magnet brake 14, first, the brake stator 141 of the permanent magnet brake 14 is fixed by the fixing member 2, and then a feeler gauge matching the required gap size is placed at the expected gap position between the brake stator 141 and the brake rotor 142. Subsequently, the fixing member 2 is moved so that the fixing member 2 moves in a direction close to the driving member 3. During the movement, the feeler gauge must be carefully observed until the feeler gauge is completely clamped between the brake stator 141 and the brake rotor 142, that is, the gap between the brake stator 141 and the brake rotor 142 reaches the preset value. After confirming that the gap adjustment is completed, the feeler gauge is moved. Remove it from between the brake stator 141 and the brake rotor 142. After completing the gap adjustment, connect the electromagnetic coil of the permanent magnet brake to the power supply. In the power-on state, carefully observe the movement state of the brake rotor 142, including whether it stops rotating, whether the deceleration process is smooth, and whether it finally stops completely. At the same time, measure and record the voltage, current, braking torque and other parameters of the permanent magnet brake 14. Then, cut off the power to the electromagnetic coil of the permanent magnet brake 14, and generate a braking torque on the brake rotor 142 through the action of magnetic force. In the power-off state, carefully observe the movement state of the brake rotor 142, including whether it stops rotating, whether the deceleration process is smooth, and whether it finally stops completely. At the same time, measure and record the braking torque and other parameters of the permanent magnet brake 14. Based on the measured data and observed phenomena, conduct a comprehensive evaluation of the performance of the permanent magnet brake 14 to determine whether it meets the preset performance index requirements.

[0031] The torque sensor 4 is installed between the brake rotor 142 and the driving member 3 to connect the brake rotor 142 and the driving member 3. Specifically, after the servo motor is decelerated by the reducer, its output torque is first transmitted to the torque sensor 4, and then the precisely measured torque is transmitted to the brake rotor 142 of the permanent magnet brake 14 through the coupling. When the electromagnetic coil of the permanent magnet brake 14 is in the power-off state, the brake stator 141 and the brake rotor 142 are tightly attracted together due to the magnetic force. At this time, the servo motor is started to drive the brake rotor 142 to rotate. Since the brake stator 141 is fixed, a relative displacement will occur between the brake rotor 142 and the stator. The torque generated in this process will be measured and recorded by the torque sensor 4. If the measured torque fails to meet the preset requirement, the servo motor continues to drive the brake rotor 142 to rotate. As the brake rotor 142 continues to rotate, the contact rotation friction between the brake rotor 142 and the brake stator 141 increases, and the contact area between the two increases, thereby generating greater friction. In this process, the torque will gradually increase until it meets the preset requirement.

[0032] Through the above structure, during the detection process of the permanent magnet brake detection device provided by the present invention, first, the brake stator 141 of the permanent magnet brake 14 is fixed by the fixing part 2, the permanent magnet brake is energized, and then a feeler gauge matching the required gap size is placed at the expected gap position between the brake stator 141 and the brake rotor 142. Subsequently, the fixing part 2 is moved so that the fixing part 2 moves in the direction close to the driving part 3. During the movement, the feeler gauge must be carefully observed until the feeler gauge is completely clamped between the brake stator 141 and the brake rotor 142, that is, the gap between the brake stator 141 and the brake rotor 142 reaches the preset value. After confirming that the gap adjustment is completed, the feeler gauge is removed from between the brake stator 141 and the brake rotor 142. After completing the gap adjustment, the electromagnetic coil of the permanent magnet brake 14 is powered on, and the brake stator 141 exerts magnetic force on the brake rotor 142. Generate braking torque. In the power-on state, carefully observe the movement state of the brake rotor 142, including whether it stops rotating, whether the deceleration process is smooth, and whether it finally stops completely. At the same time, measure and record the voltage, current, braking torque and other parameters of the permanent magnet brake 14. Then, cut off the power to the electromagnetic coil of the permanent magnet brake 14, so that the brake stator 141 and the brake rotor 142 are tightly attracted due to the magnetic force. Then, start the servo motor to drive the rotor to rotate. At this time, since the brake stator 141 is fixed, relative displacement will occur between the brake stator 141 and the brake rotor 142 and friction will be generated. The torque sensor 4 will measure the torque value in real time. If the measured torque does not meet the preset requirement, continue to drive the brake rotor 142 to rotate and rub against the brake stator 141, thereby gradually increasing the torque value until the contact rotation friction between the brake rotor 142 and the brake stator 141 reaches the preset torque. Therefore, the permanent magnet brake detection device can not only measure the torque value, but also, based on the measurement results, enable the servo motor to drive the brake rotor 142 and the brake stator 141 to gradually reach the preset torque through contact rotation friction, thereby reducing the multiple loading and unloading of the permanent magnet brake 14 resulting in reduced product quality and improving detection efficiency.

[0033] An optional implementation of this embodiment is as follows: In order to facilitate the movement of the fixing member 2, the permanent magnet brake detection device also includes a guide rail 5 and a first vertical plate 6. The guide rail 5 is installed on the base plate 1, and the first vertical plate 6 has a slider or roller that matches the guide groove of the guide rail 5, so that the first vertical plate 6 can slide along the guide rail 5.

[0034] The fixing member 2 is installed on one side of the first vertical plate 6, and the first vertical plate 6 can slide along the guide rail 5. Therefore, when it is necessary to adjust the gap between the brake stator 141 and the brake rotor 142, it is only necessary to push or pull the first vertical plate 6 to move the fixing member 2 and the permanent magnet brake 14 thereon, thereby achieving the purpose of adjusting the gap size.

[0035] An optional implementation of this embodiment is as follows: In order to more accurately adjust the position of the fixing part 2, the permanent magnetic brake detection device also includes a second vertical plate 7, a third vertical plate 8 and a screw 9, wherein the second vertical plate 7 and the third vertical plate 8 are both installed on the base plate 1 and are located on the side of the first vertical plate 6 away from the fixing part 2, and the third vertical plate 8 is located on the side of the first vertical plate 6 close to the fixing part 2, and the permanent magnetic brake 14 is installed between the third vertical plate 8 and the first vertical plate 6.

[0036] One end of the lead screw 9 is rotatably mounted on the third vertical plate 8 through bearings and other components, and the other end extends toward the first vertical plate 6. A threaded hole matching the lead screw 9 is provided on the first vertical plate 6. The first vertical plate 6 is connected to the first vertical plate 6 and the lead screw 9 by screwing. When the lead screw 9 rotates, due to the meshing action of the thread, the first vertical plate 6 will move along the axial direction of the lead screw 9. By controlling the rotation speed and direction of the lead screw 9, the position adjustment of the first vertical plate 6 and the permanent magnetic brake 14 on the fixing part 2 is realized.

[0037] An optional implementation of this embodiment is as follows: In order to facilitate the rotation of the screw 9, the permanent magnet brake detection device also includes a hand wheel 10, which is installed on the end of the screw 9 away from the third vertical plate 8. When the operator needs to adjust the distance between the stator of the permanent magnet brake 14 and the brake rotor 142, he only needs to simply hold the hand wheel 10 and rotate it clockwise or counterclockwise. As the hand wheel 10 rotates, the force is transmitted to the screw 9 connected thereto, driving the screw 9 to rotate. Since the first vertical plate 6 is screwed onto the screw 9, the rotation of the screw 9 will be directly converted into the movement of the first vertical plate 6 on the guide rail 5, thereby realizing the adjustment of the brake position. The hand wheel 10 not only simplifies the adjustment process, but also makes the operation more labor-saving. The operator does not need to use additional tools or equipment, and only needs to rotate the hand wheel 10 to complete the control of the adjustment process of the position of the fixing member 2.

[0038] An optional implementation of this embodiment is as follows: In order to facilitate the sliding of the first vertical plate 6, the permanent magnet brake detection device also includes, one end of the sliding rod 11 is installed on the second vertical plate 7, and the other end is installed on the third base plate 1, the first vertical plate 6 is slidably installed on the sliding rod 11, and the axial direction of the sliding rod 11 is parallel to the axial direction of the screw 9. The sliding rod 11 not only provides a guide for the sliding of the first vertical plate 6, but also can support the first vertical plate 6. Under the guidance of the sliding rod 11, the first vertical plate 6 can move along the axial direction of the sliding rod 11.

[0039] An optional implementation of this embodiment is as follows: In order to firmly fix the position of the first vertical plate 6 after adjusting its position, the permanent magnetic brake detection device further includes a fixture 12, which is mounted on the first vertical plate 6. The fixture 12 is used to be fixed to the slide bar 11. Each fixture 12 corresponds to a slide bar 11 one by one, ensuring that the fixture 12 can accurately lock the slide bar 11, thereby fixing the position of the first vertical plate 6. The interior of the fixture 12 is designed with a sliding groove or sliding hole that matches the slide bar 11, so that the fixture 12 can slide along the slide bar 11. During the process of adjusting the position of the first vertical plate 6, the fixer 12 will slide to the desired position together with the first vertical plate 6. When the position adjustment is completed, the operator can rotate or press the fixer 12 to make the fixer 12 tightly engage with the slide bar 11, thereby achieving the fixation of the slide bar 11 by the fixer 12, thereby reducing the axial movement of the first vertical plate 6 when subjected to external force, ensuring the accuracy and stability of the detection. The fixer 12 can be a clamp or the like that abuts against the slide bar 11, thereby generating friction with the slide bar 11, thereby preventing the movement of the first vertical plate 6.

[0040] An optional implementation of this embodiment is as follows: the fixing part 2 is a three-jaw chuck. By placing the permanent magnetic brake 14 between the jaws of the three-jaw chuck and adjusting the degree of opening of the jaws, the brake can be quickly clamped and fixed. The three-jaw chuck is installed on one side of the first vertical plate 6. When the permanent magnetic brake 14 needs to be installed or replaced for inspection, the operator only needs to adjust the degree of opening of the jaws to open or close the jaws, thereby easily completing the clamping and release of the brake. At the same time, the three-jaw chuck can also clamp permanent magnetic brakes 14 of different specifications and sizes. By adjusting the position and opening degree of the jaws, effective clamping of brakes of various specifications can be achieved, further improving the versatility and flexibility of the detection device. The three-jaw chuck serves as the fixing part 2, which not only realizes the firm clamping and quick installation of the permanent magnetic brake 14, but also can be flexibly adjusted according to permanent magnetic brakes 14 of different specifications.

[0041] An optional implementation of this embodiment is as follows: one end of the connecting shaft 13 is transmission-connected to the driving member 3, and the other end is connected to the brake rotor 142. Specifically, the torque sensor 4 can be designed to be directly connected between the two connecting shafts 13, with one end of the two connecting shafts 13 being connected to the driving member 3 and the brake rotor 142 respectively, and the other end being connected to the torque sensor 4 to measure the torque transmitted therebetween. It can also be a torque sensor 4 installed circumferentially on the connecting shaft 13, which indirectly measures the torque value by measuring the deformation or phase difference generated when the shaft is subjected to torque.

[0042] To sum up, through the above structure, during the detection process of the permanent magnet brake detection device provided by the present invention, first, the brake stator 141 of the permanent magnet brake 14 is fixed by the fixing part 2, and then a feeler gauge matching the required gap size is placed at the expected gap position between the brake stator 141 and the brake rotor 142. Subsequently, the hand-cranked wheel 10 is rotated. As the hand-cranked wheel 10 rotates, the force is transmitted to the screw 9 connected thereto, driving the screw 9 to rotate. The rotation of the screw 9 will be directly converted into the movement of the first vertical plate 6 on the guide rail 5, thereby realizing the adjustment of the position of the permanent magnet brake 14, and moving the fixing part 2 so that the fixing part 2 moves in the direction close to the driving part 3. During the movement of the first vertical plate 6, the feeler gauge must be carefully observed until the feeler gauge is completely clamped between the brake stator 141 and the brake rotor 142, that is, the gap between the brake stator 141 and the brake rotor 142 reaches the preset value. After confirming that the gap adjustment is completed, the feeler gauge is removed from between the stator and the rotor. After the adjustment is completed, the first vertical plate 6 is fixed to the slide rod 11 using the fixing piece 2, and then the electromagnetic coil of the permanent magnet brake 14 is powered on. In the powered-on state, the movement state of the brake rotor 142 is carefully observed. At the same time, the voltage, current, braking torque and other parameters of the permanent magnet brake 14 are measured and recorded. Then, the electromagnetic coil of the permanent magnet brake 14 is powered off, so that the brake rotor 142 and the brake stator 141 are tightly attracted due to the magnetic force. Then, the servo motor is started to drive the brake rotor 142 to rotate. At this time, since the brake stator 141 is fixed, a relative displacement will occur between the brake rotor 142 and the brake stator 141 and friction will be generated. The torque sensor 4 will measure the torque value in real time. If the measured torque does not meet the preset requirement, the brake rotor 142 will continue to be driven to rotate and rub against the brake stator 141, thereby gradually increasing the torque value until the contact rotation friction between the brake rotor 142 and the brake stator 141 reaches the preset torque. Therefore, the permanent magnet brake detection device can not only measure the torque value, but also, based on the measurement results, enable the servo motor to drive the brake rotor 142 and the brake stator 141 to gradually reach the preset torque through contact rotation friction, thereby reducing the multiple loading and unloading of the permanent magnet brake 14 resulting in reduced product quality and improving detection efficiency.
