Specific embodiments

[0015] For a further understanding of the purpose, structure, features, and functions of the present invention, the following is a detailed description in conjunction with embodiments.

[0016] Please refer to Figure 1 , the present invention provides a motor type detection bench, the detection bench includes a bottom platform 1, a motor mounting bracket 2, and a detection device 3; the motor mounting bracket 2 and the detection device 3 are respectively detachably mounted on both sides of the bottom platform 1; the detection device 3 includes a detection box 31; a box receiving platform 32 is provided below the detection box 31; the receiving platform 32 is detachably mounted on the bottom platform 1 by bolts; water inlets 311 and water outlets 312 are respectively provided on both sides of the middle part above the detection box 31; a torque and speed sensor 30 is further provided in the middle of the front end of the detection box 31; a sensor fixing seat 33 is further provided below the torque and speed sensor 30; the torque and speed sensor 30 is detachably mounted on the sensor fixing seat 33.

[0017] The motor mounting bracket 2 and the detection device 3 are detachably mounted on both sides of the base 1, making the assembly, disassembly and maintenance of the equipment more convenient. Different equipment configurations can be adjusted according to actual needs, enhancing the flexibility of the equipment. The detachable design of the box body receiving platform 32 enhances the versatility of the base. The box body receiving platform 32 can be easily replaced or maintained to adapt to the motor detection requirements of different specifications. The water inlet 311 and the water outlet 312 are arranged on both sides of the detection box body 31, facilitating the liquid flow, ensuring the smooth flow of water, and making the management of water inlet and outlet clearer and more efficient. The detachable installation between the torque and speed sensor 30 and the sensor fixing seat 33 ensures the accurate positioning and firm fixation of the sensor, facilitating data collection during the detection process and improving the accuracy of the detection.

[0018] The setting of the torque and speed sensor 30 is the core part of this detection platform. Through this sensor, the torque and speed data of the motor can be monitored in real time, which helps to accurately measure the performance of the motor and ensure the reliability of the detection results. The design of the sensor fixing seat 33 makes the sensor installation stable, avoiding possible vibration or error during use and ensuring the high precision of the measured data. Preferably, a first docking claw 34 is provided on the output shaft at one end of the detection box body 31; second docking claws 35 and third docking claws 36 are respectively provided at the left and right ends of the torque and speed sensor 30; the first docking claw 34 and the second docking claw 35 are snap-connected.

[0019] The snap connection design of the first docking claw 34 and the second docking claw 35 helps to ensure the tight connection between the output shaft and the torque and speed sensor, avoiding loosening caused by vibration or external force. This snap connection method can provide high stability, ensuring that the sensor accurately measures torque and speed. By setting multiple claw docking, the design realizes fast and convenient assembly and disassembly. The operator can easily connect or remove the output shaft and the sensor assembly without complex tools or additional operation steps. This design effectively reduces the difficulty of manual operation and improves work efficiency.

[0020] The connection method of the output shaft, the sensor and the claw makes the whole detection system have strong adaptability and can be applied to different specifications, different types of equipment or detection environments. The claw design provides a certain degree of flexibility and can adapt to different installation methods and space requirements. At the same time, by fixing the sensor and the shaft in a snap connection way, the wear risk brought by traditional screws or other connection methods can be avoided, especially in the case of long-term use. The claw connection can maintain a good fixing effect under the action of long-term vibration and load, thus reducing the loss of the equipment.

[0021] Preferably, the motor mounting frame 2 includes a mounting frame bottom plate 21 and a motor receiving platform 22; the mounting frame bottom plate 21 and the base 1 are detachably arranged; the motor receiving platform 22 is fixedly installed on the mounting frame bottom plate 21; the motor receiving platform 22 is provided with a penetrating fixing ring 23; reinforcing ribs 24 are also provided on both side ends of the motor receiving platform 22; one end of the side surface of the reinforcing rib 24 is connected to the side end of the motor receiving platform 22, and the other end is connected to the side end of the mounting frame bottom plate 21; the bottom surface of the reinforcing rib 24 is also connected to the upper surface of the base 1.

[0022] The mounting frame bottom plate 21 and the base 1 are detachably arranged, so that the motor mounting frame has greater flexibility and can be installed or disassembled as needed; it is not only convenient for operation and maintenance, but also can cope with different usage scenarios and needs; the reinforcing ribs 24 connect the two side ends of the motor receiving platform 22 and the mounting frame bottom plate 21, and the bottom surface is connected to the upper surface of the base 1, which can effectively enhance the tensile and compressive strength of the entire mounting frame, ensuring that the motor will not be deformed or damaged due to excessive force during operation. The reinforcing ribs 24 are reasonably distributed and can disperse pressure when bearing external loads, thereby improving the overall bearing capacity of the structure. The motor receiving platform 22 is fixedly mounted on the mounting frame bottom plate 21, and the motor receiving platform 22 is provided with a through fixing ring 23, which can ensure the stable installation of the motor and prevent the motor from being displaced or shaken during operation. The design of the fixing ring 23 makes the motor installation more precise, improves the docking accuracy of the motor, and ensures the accuracy of detection.

[0023] Since the motor may generate large vibrations during operation, the design of the reinforcing ribs 24 can effectively enhance the anti-vibration performance of the equipment, reduce the impact of vibration, and make the motor mounting frame more durable and stable. Its structural design can keep the components tightly connected to avoid loosening or wear of components due to vibration.

[0024] Preferably, an anti-slip coating 231 is further provided on the inner wall of the fixing ring 23 .

[0025] The addition of the anti-slip coating 231 can effectively increase the friction between the fixing ring 23 and the fixed component (such as a motor or other components). By increasing the friction coefficient, the possibility of sliding or loosening is reduced, ensuring that the fixing ring firmly fixes the connected component, thereby enhancing the stability and safety of the connection.

[0026] Preferably, the detection device 3 is also provided with an electrical control system connected to the motor mounting bracket 2 and connected to a torque and speed sensor 30 to monitor the working condition of the motor in real time.

[0027] The connection between the electrical control system and the torque and speed sensor 30 enables the operating state of the motor to be monitored through real-time data. This means that key parameters such as torque and speed during the operation of the motor can be accurately understood, ensuring that the motor is within the normal operating range and promptly detecting any abnormal conditions. This helps to improve the operating safety of the motor and prevent shutdowns or more serious damage caused by equipment failures.

[0028] By monitoring the operating conditions of the motor in real time, the detection device can promptly feedback the operating state of the motor. If abnormal fluctuations occur in torque or speed, the system can issue an alarm or automatically adjust the operating parameters of the motor, thereby preventing the equipment from being damaged due to overload, overheating or other reasons. Such a warning mechanism improves the reliability and stability of the equipment and avoids equipment failures caused by unknown problems.

[0029] Preferably, a spiral cooling pipe 313 is provided inside the detection box body 31. The inlet end of the cooling pipe 313 is communicated with the water inlet 311, and the outlet end is communicated with the water outlet 312. Heat dissipation fins 314 are provided on the outer surface of the pipe wall of the cooling pipe 313.

[0030] The design of the spiral cooling pipe 313 can increase the flow path of the water flow, causing the water flow to form a spiral flow inside the pipe, thereby enhancing the residence time of the water flow. This helps to improve the heat exchange efficiency, enabling the cooling water to effectively absorb the heat from the equipment inside the detection box body, so as to keep the equipment operating at a lower temperature.

[0031] The setting of the heat dissipation fins 314 on the outer surface of the pipe can significantly increase the heat exchange surface area. By expanding the contact area with the air, the heat dissipation fins enhance the heat conduction ability to the surrounding environment, further strengthening the cooling effect. This helps to effectively dissipate heat, avoid excessive temperature inside the detection box body, and ensure the normal operation of the equipment.

[0032] Preferably, a shock-absorbing component 11 is provided between the base 1 and the mounting frame bottom plate 21; the shock-absorbing component 11 includes an upper connecting plate 111, a lower connecting plate 112, and a rubber shock-absorbing pad 113 provided therebetween; wave-shaped grooves 114 are provided on the surface of the rubber shock-absorbing pad 113.

[0033] By providing the shock-absorbing component 11 between the base 1 and the mounting frame bottom plate 21, especially the use of the rubber shock-absorbing pad 113, the vibrations and noises generated during the operation of the equipment or components can be effectively reduced. This helps to protect the equipment from vibration, extend its service life, and at the same time improve the working environment and reduce the interference of vibration to other components or equipment.

[0034] The wavy grooves 114 of the rubber shock pad 113 are designed to increase the friction of the contact surface, thereby improving the shock absorption effect, avoiding excessive offset or shaking of the equipment during operation, and further enhancing the stability of the equipment. The wavy grooves not only provide better shock absorption, but also help to disperse vibrations and improve the seismic resistance of the entire system.

[0035] Preferably, a support frame 4 is provided at the rear end of the motor mounting bracket 2; the cross-section of the support frame 4 is in a Y-shaped structure; the open end of the Y-shaped structure faces the bottom surface of the detection box body 31; the material of the open end of the support frame 4 is fluororubber; the support end of the support frame 4 adopts a height adjustment mechanism 41; the height adjustment mechanism 41 includes an adjustment screw 411 and a locking nut 412.

[0036] The Y-shaped structure of the support frame 4 provides good support performance. Especially the design that the open end faces the bottom surface of the detection box body 31 enables the support frame to firmly support the motor mounting bracket 2 and avoid the instability of the motor mounting bracket caused by vibration or external force. The distribution design of the Y-shaped structure makes the support frame have high strength and stability, which can effectively disperse the load and reduce the pressure on the support frame during the operation of the motor.

[0037] The use of fluororubber material at the open end of the support frame 4 effectively reduces vibration transmission. Fluororubber has good elasticity and shock absorption performance, can absorb the vibrations generated during the operation of the motor, and reduce the impact of vibrations on the detection box body and surrounding equipment. In addition, fluororubber also has characteristics such as corrosion resistance and high temperature resistance, can adapt to various working environments, and improve the durability of the equipment.

[0038] The height adjustment mechanism 41 (including the adjustment screw 411 and the locking nut 412) of the support frame 4 enables the height of the support frame to be adjusted according to actual needs. This design enables the support frame to adapt to different height requirements and provides flexibility. For example, if the working environment of the motor requires a change in height, or it is necessary to adjust the support frame to ensure that the motor is in an ideal working position, the adjustment mechanism can easily achieve these adjustments.

[0039] Specific implementation: The motor mounting bracket 2 and the detection device 3 are respectively installed on both sides of the base table 1. The motor is fixed to the detection table through the motor mounting bracket 2, and the detection box body 31 of the detection device 3 is used to monitor the operation of the motor. During operation, the motor starts and runs, and the water inlet 311 and the water outlet 312 in the detection box body 31 are responsible for the operation of the water cooling system. The water flow passes through the spiral cooling pipe 313 to provide cooling for the detection device, and the heat dissipation fins 314 on the surface of the pipe enhance the heat dissipation effect. At the same time, the torque and speed sensor 30 monitors the torque and speed data of the motor in real time and transmits the data to the electrical control system connected to the motor mounting bracket 2 to ensure that the working state of the motor is monitored in real time. The sensor fixing seat 33 maintains the stable position of the torque and speed sensor 30, and the torque and speed sensor is connected to the detection box body 31 through the second and third docking claws 35 and 36 and the first docking claw 34 to ensure stable installation. A shock absorption component 11 is installed between the base table 1 and the mounting bracket bottom plate 21 to effectively reduce the vibration generated during work, and the wavy grooves 114 of the rubber shock absorption pad 113 further improve the shock absorption effect. During the detection process, the support frame 4 provides stable support, and the height of the support frame is adjusted through the height adjustment mechanism 41 to ensure the stability and accuracy of the detection table under different usage scenarios. The design and working process of the entire device ensure the efficiency, stability, and accuracy of the detection process through the electrical control system and precise mechanical connections.
