Description

Technical Field

[0001] This utility model relates to the field of motor testing technology, specifically to an integrated motor testing device. Background Technology

[0002] An electric motor is an electromagnetic device that converts or transmits electrical energy based on the law of electromagnetic induction. Its main function is to generate driving torque, serving as a power source for electrical appliances or various machines. After a motor is manufactured or repaired, testing its characteristics and the performance of the entire drive system are essential for analyzing and controlling the motor and drive system. This process helps determine whether the motor can function properly and to understand its performance.

[0003] In the process of realizing this utility model, the inventors discovered that the prior art has at least the following problems: In traditional motor testing, such as testing the surface temperature of the motor and the runout test during the rotation of the output shaft, the test operation methods are cumbersome and involve many complex steps. Due to functional limitations, multiple tests are often required to obtain various technical parameters of the product. In addition, due to the wide variety of existing motors and the large number of size series, multiple experimental devices of different specifications are required when testing different motors, which not only increases the cost but also brings inconvenience to the testing work. Utility Model Content

[0004] In view of this, the purpose of this utility model is to provide an integrated motor testing device to solve the problems of cumbersome and complex test methods and many steps in traditional motor testing, such as testing the surface temperature of the motor and the runout test during the rotation of the output shaft. Due to functional limitations, multiple tests are often required to obtain various technical parameters of the product. In addition, due to the wide variety of existing motors and the large number of size series, different specifications of experimental devices are required to test different motors, which not only increases the cost, but also brings inconvenience to the testing work.

[0005] To achieve the above objectives, this utility model employs the following technical solution:

[0006] An integrated testing device for motors includes a fixed base with a horizontal top surface. A test motor to be tested is mounted on the top surface of the fixed base, and the test motor is locked in place by locking screws on the top surface of the fixed base. A swingable temperature sensor is mounted above the fixed base. A vision camera base is fixedly mounted on the top surface of the fixed base, and a high-speed vision camera is mounted on the surface of the vision camera base. A runout testing chamber is fixedly mounted on the top of the fixed base, and a dial indicator for measuring runout is mounted on the surface of the runout testing chamber.

[0007] As a preferred technical solution of this utility model, the bottom end of the fixed base is provided with four support legs, and the bottom end of each support leg is fixed with a fixed foot of a disc structure.

[0008] As a preferred embodiment of this utility model, the dial indicator includes a connecting rod fixed to the top of the probe of the dial indicator, and a test pen with an arc shape is provided at the top of the connecting rod, the inner wall of the arc of the test pen being a smooth curved surface.

[0009] As a preferred technical solution of this utility model, a support frame is fixedly installed on the top of the fixed base. A sliding hole is provided on the front end face of the support frame. A lifting slide is slidably connected to the surface of the sliding hole. An ear plate is provided on the surface of the lifting slide. A shaft is hinged to the surface of the ear plate. A swing rod is fixed to the surface of the shaft. A temperature sensor is located at the top of the swing rod.

[0010] As a preferred technical solution of this utility model, a locking block is provided on the rear end face of the support frame. The locking block is correspondingly provided with the lifting slide. Threaded holes are provided on both the rear end face of the lifting slide and the surface of the locking block. A screw connection is provided between the threaded hole on the rear end face of the lifting slide and the threaded hole on the surface of the locking block. A locking nut is provided at the top of the screw.

[0011] As a preferred technical solution of this utility model, both the surface of the ear plate and the surface of the shaft cylinder are provided with through threaded holes, and screws are provided in the threaded holes for connection, with a rotating torsion table provided at the top of the screw.

[0012] As a preferred embodiment of this utility model, the surface of the temperature sensor is covered with a cylindrical iron sheet.

[0013] The beneficial effects of this utility model are as follows:

[0014] This invention features a horizontal top surface on the fixed base, facilitating the installation of the test motor. The test motor is secured with locking screws on the top surface of the fixed base, enhancing its installation stability. A swingable temperature sensor is positioned above the fixed base, allowing for contact temperature measurement of the test motor's surface after a certain period of operation at room temperature. A vision camera base is fixedly mounted on the top surface of the fixed base, and a high-speed vision camera is mounted on its surface. The camera captures the runout trajectory of the output shaft of the test motor during rotation at high speed. A runout test chamber is fixedly installed on the top of the fixed base. A dial indicator for measuring runout is set on the surface of the runout test chamber. A connecting rod is fixed to the top of the dial indicator through the probe. The top of the connecting rod is set with an arc-shaped test pen. The test pen contacts the surface of the output shaft of the test motor. When the output shaft runs during rotation, the surface of the output shaft comes into contact with the smooth curved inner wall of the test pen, pushing the connecting rod and the probe of the dial indicator to run out of space. The runout value of the output shaft of the test motor is then displayed by the dial indicator.

[0015] This invention features a support frame fixedly mounted on the top of a fixed base. The front face of the support frame has a sliding hole, and a lifting slide is slidably connected to the surface of the sliding hole. The rear face of the support frame has a locking block, which is correspondingly positioned to the lifting slide. Both the rear face of the lifting slide and the surface of the locking block have threaded holes. A screw connects the threaded hole on the rear face of the lifting slide and the threaded hole on the surface of the locking block, with a locking nut at the top of the screw. This allows for adjustment of the ear plate's height, thereby adjusting the height of the swing arm and temperature sensor. This facilitates better testing of the motor surface contact by adjusting the temperature sensor surface, effectively improving the accuracy of temperature testing during the contact process.

[0016] The surface of the lifting slide is provided with ear plates, and a shaft cylinder is hinged to the surface of the ear plates. A swing rod is fixed to the surface of the shaft cylinder. The temperature sensor is located at the top of the swing rod. The surface of the temperature sensor is covered with a cylindrical iron sheet. The iron sheet has high thermal conductivity and protects the internal temperature sensor from damage while ensuring good temperature transmission.

[0017] This invention features through-hole threaded holes on both the surface of the ear plates and the surface of the shaft cylinder. Screws are installed in the threaded holes for connection, and a rotating torsion table is provided at the top of the screw. By rotating the screw, the two ear plates are tightened and clamped towards the center, thereby clamping and fixing the shaft cylinder and realizing the adjustment of the swing arm angle.

[0018] The temperature sensor used in this application is a PT100 temperature sensor probe from Dingyan. An iron sheet is wrapped around the probe surface. The temperature sensor has an external cable with an interface at the top that connects to an external display device to view the temperature value in real time.
