[0002] The motor brake is a device that can stop the motor quickly. It has the functions of braking, stopping and protecting the motor. If the motor fails or runs unstably during operation, the brake can stop the motor in time to avoid safety accidents. If the motor is installed vertically, the brake can also prevent the motor from rotating due to the gravity of the workpiece. Therefore, whether the motor brake torque is qualified plays a vital role in the safe use of the motor.

[0003] At present, the industry's detection of servo motor torque is mostly limited to manual sampling using torque wrenches, which consumes a lot of time and energy, and external forces can easily damage the appearance and structure of the motor. Therefore, this test is generally a sampling method, which is inefficient.

[0004] Therefore, in view of this, the existing structural deficiencies are studied and improved, and a servo motor brake torque testing device is proposed. Utility Model Content

[0007] Furthermore, the height clearance of the support plate from the ground is adjusted by a gasket, and the size of the side groove of the support plate matches the clearance of the outer shape of the pressure roller.

[0008] Furthermore, the height gap between the pressing plate and the supporting plate is tightly matched with the load motor, and the pressing plate and the pressure roller are fixed above the matching gap by a fastening nut.

[0012] Furthermore, a slot is provided on the top of the slide seat, and the slot is plugged into and matched with the plug block.

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] 1. When the utility model is in use, in order to adapt to the different center heights of different test motors, the present application can adjust the height gap between the bottom support plate of the load motor and the slide seat by adding or reducing the design of the horseshoe-shaped gasket through the setting of the installation component, so as to ensure the coaxiality of the load motor and the power motor.

A support plate 802 is arranged below the load motor 801, and a pressure plate 803 is arranged above the load motor 801, and side grooves 804 are symmetrically provided on both sides of the support plate 802 and the pressure plate 803, pressure rollers 805 are symmetrically arranged on both sides of the load motor 801, and an insertion block 806 is fixed at the root of the pressure roller 805, a horseshoe-shaped gasket 807 is inserted at the root of the pressure roller 805, and a fastening nut 808 is threadedly matched with the top thread of the pressure roller 805, the support plate 802 adjusts the height clearance from the ground through the gasket 807, and the size of the side groove 804 on the side of the support plate 802 is consistent with the pressure The roller 805 has a clearance fit in shape, and the height gap between the pressure plate 803 and the support plate 802 is tightly fitted with the load motor 801, and the pressure plate 803 and the pressure roller 805 are fixed above the clearance by a fastening nut 808. In order to adapt to the different center heights of different test motors, the present application can adjust the height gap between the bottom support plate 802 of the load motor 801 and the slide 6 by increasing or decreasing the design of the horseshoe-shaped gasket 807 through the setting of the installation component 8, so as to ensure the coaxiality of the load motor 801 and the power motor 4. In addition, the load motor 801 is placed between the bottom support plate 802 and the top pressure plate 803, and the bottom plug block 806 of the pressure roller 805 is correspondingly inserted into the top slot 7 of the slide 6 and fixed by the fastening nut 808, so as to realize the stable installation of the load motor 801, avoid data instability caused by vibration during the test, reduce the measurement accuracy and even damage the torque sensor 2;

[0022] like Figure 1 to Figure 2 As shown, a torque sensor 2 is bolted to the middle of the workbench 1, and couplings 3 are connected to the rotating shafts on both sides of the torque sensor 2. A power motor 4 is bolted to the other end of the workbench 1, and the power motor 4 transmits torque to the load motor 801 through the torque sensor 2.

The power motor 4 and the load motor 801 are connected to the two ends of the torque sensor 2 through the coupling 3. By increasing the input current of the power motor 4, the dragging torque is increased until it is driven to detect that the dragged load motor 801 has a rotational displacement, and the current at this time is recorded and converted into the output torque of the power motor 4. The output torque at this time is the braking torque of the brake.

[0023] Working principle: When using this servo motor brake torque testing device, in order to adapt to the different center heights of different test motors, the present application, through the setting of the installation component 8, can adjust the height gap between the bottom support plate 802 of the load motor 801 and the slide 6 by increasing or decreasing the design of the horseshoe-shaped gasket 807, so as to ensure the coaxiality of the load motor 801 and the power motor 4. In addition, the load motor 801 is placed between the bottom support plate 802 and the top pressure plate 803, and the bottom plug 806 of the pressure roller 805 is correspondingly inserted into the top slot 7 of the slide 6 and fixed by the tightening nut 808, so as to achieve a stable installation of the load motor 801 and avoid the test process. The data is unstable due to vibration, which reduces the measurement accuracy and even damages the torque sensor 2. When in use, the power motor 4 and the load motor 801 are connected to the two ends of the torque sensor 2 through the coupling 3. By increasing the input current of the power motor 4, the dragging torque is increased until the driver detects that the dragged load motor 801 has a rotational displacement, and records the current at this time, which is converted into the output torque of the power motor 4. The output torque at this time is the braking torque of the brake. Through the structural design of the test bench of this application, compared with the existing technology of manual sampling using a torque wrench, the detection efficiency and test accuracy can be effectively improved, and the practicality is stronger.
