Description

Technical Field

[0001] The utility model relates to the technical field of servo motor detection, in particular to a servo motor temperature resistance detection device. Background Art

[0002] A servo motor is an engine that controls the operation of mechanical components in a servo system. It is also an auxiliary motor indirect speed change device. The servo motors currently on the market have internal structures such as circuit boards that can control speed, and their control position accuracy is accurate. They can also convert voltage signals into torque and speed to drive the controlled object. In addition, compared with single-phase asynchronous motors, servo motors have significant characteristics such as large starting torque, wide operating range, and no self-rotation.

[0003] At the same time, the servo motors currently on the market have structures such as electronic control boards installed inside them, so during the production process of the servo motors, it is necessary to perform temperature resistance tests on the servo motors in order to understand the working temperature of the servo motors. However, when using existing temperature resistance testing devices, most of them directly place the servo motors inside the testing devices, and the bottom of the servo motor after placement is directly placed on the bottom of the inner cavity of the testing device, and the required fixation of the servo motor is completed through corresponding connections. However, the servo motor connected in this way has its bottom in contact with the bottom of the inner cavity of the testing device, so when performing the required temperature resistance test, some parts of the bottom of the servo motor cannot be heated or the heating is unreliable, which causes the bottom of the servo motor to be poorly heated during the testing process, which can easily lead to inaccurate testing of the servo motor.

[0004] In addition, after use, most of the existing detection devices directly take out the servo motor or wait for it to cool down before taking it out. However, after actual testing, the temperature inside the device after heating will make the servo motor also have a higher temperature. If it is taken out directly, it is easy to burn the staff, and waiting for natural cooling takes a long time, which affects subsequent use, thereby reducing the applicability of the detection device. Summary of the invention

[0005] In view of the above-mentioned deficiencies, the utility model provides a detection device which can accurately obtain the temperature resistance detection data of the servo motor to be detected.

[0006] In order to achieve the above purpose, the utility model adopts a servo motor temperature resistance detection device, including a detection box, a box door hinged on one side of the detection box, a controller is arranged outside the detection box, and a storage rack, a power connection area for connecting the servo motor to be detected, a heater for heating the inside of the detection box, and a temperature detector for detecting the temperature of the detection box are arranged inside the detection box. The electrical connection ends of the heater and the temperature detector pass through the cavity wall of the detection box respectively, and are electrically connected to the controller, and constitute the control of the heating temperature of the servo motor to be detected in the detection box;

The servo motor to be inspected is placed in the detection box through the storage table, and each surface of the servo motor to be inspected placed on the storage table is far away from each side wall of the detection box.

[0008] The beneficial effect of the above structure is that a controller is provided outside the detection box, and a storage rack, a power connection area, a heater, and a temperature detector are provided inside the detection box, and the temperature detector and the heater are electrically connected to the controller respectively, thereby achieving a reliable heating in the temperature detection box through the action of the temperature detector, the heater and the controller during the servo motor test phase, and the temperature condition in the box can be monitored in real time, and the required temperature adjustment action can be performed. In addition, the utility model adopts an upper storage rack provided in the detection box, and a storage table with a hollow position is involved on the storage rack, thereby enabling the servo motor to be placed through the position of the storage table when a temperature resistance test is required, thereby enabling when the temperature resistance test is started, after the heating in the detection box, the hot air in the detection box can pass through the hollow position on the storage table and act on the bottom position of the servo motor, thereby enabling the servo motor to achieve uniform temperature on all sides of the servo motor during the temperature resistance test phase, thereby ensuring the accuracy of the data of the servo motor after the test.

[0009] The utility model is further configured as follows: a ventilation slot is provided on the cavity wall of the detection box, a heat dissipation opening and closing mechanism for opening or closing the ventilation slot is provided in the detection box, a fan is provided outside the detection box at a position relative to the ventilation slot, the fan is electrically connected to the controller, and performs the opening and closing actions of the fan, and through the fan and the ventilation slot, efficient heat dissipation in the detection box is formed after the temperature resistance test is completed; the heat dissipation opening and closing mechanism includes a guide slide bar connected to the detection box and located on both sides of the ventilation slot, a blocking frame arranged between the two guide slide bars, and an electric telescopic rod driving the blocking frame to move up and down and form the opening and closing of the ventilation slot, the blocking frame includes a blocking bar for adapting to the air outlet position of the ventilation slot, during the detection stage in the detection box, the blocking bar blocks the air outlet position of the ventilation slot, and during the heat dissipation stage in the detection box, the electric telescopic rod drives the blocking frame to move up to release the blocking of the blocking bar on the air outlet position of the ventilation slot.

[0010] Through the above-mentioned arrangement, after the detection, the servo motor can achieve efficient heat dissipation and cooling in the detection box through the cooperation of the ventilation slot and the fan, that is, the servo motor can be cooled efficiently after the detection, avoiding burns if it is taken out before cooling down or waiting for natural cooling for a long time, which affects the subsequent use. In addition, by designing the heat dissipation opening and closing mechanism, the detection box can perform efficient heat dissipation after the detection without affecting the reliable implementation of the heating detection, thereby ensuring the rationality of the design of the utility model.

[0013] Through the above arrangement, the height of the storage rack can be adjusted, and after adjustment, it can be reliably locked, thereby achieving the reliability of height adjustment. At the same time, when the height of the storage rack is adjusted, the detection box can also be suitable for servo motors of different specifications and sizes to perform the required temperature resistance test, thereby greatly improving the applicability of the detection device.
