Abstract
本发明公开了提供一种端面安装电机测试系统的免对中的电机安装支架，包括支架本体，所述支架本体包括底板及两个互相平行的安装面，两个安装面上分别设有同心的止口，分别通过两个止口安装测功机和被试电机。本发明通过制造高精度的电机安装工装从而“忽略”掉对中的过程，或者说应用这种方案的工装后在进行电机测试时就不再需要对中这个工作也能保证被测电机与测功机的同心度，这样就节省了对中工作所耗费的时间以及相应的设备器材，同时由于只是单纯的将被测电机装到固定的位置，对人员技能或经验的要求就有所降低了，不同的人员操作的结果都能达到同一水平。
The present invention discloses a motor mounting bracket that does not require centering for an end-mounted motor test system, including a bracket body, wherein the bracket body includes a bottom plate and two mutually parallel mounting surfaces, wherein the two mounting surfaces are respectively provided with concentric stoppers, and a dynamometer and a motor under test are respectively mounted through the two stoppers. The present invention "ignores" the centering process by manufacturing a high-precision motor mounting tool, or in other words, after the tooling of this solution is applied, the centering work is no longer required during motor testing, and the concentricity of the motor under test and the dynamometer can be ensured, thus saving the time spent on the centering work and the corresponding equipment. At the same time, since the motor under test is simply mounted in a fixed position, the requirements for personnel skills or experience are reduced, and the results of operations by different personnel can reach the same level.
Description
Technical Field
The invention relates to motor load test, in particular to a centering-free motor mounting bracket of an end surface mounting motor test system.
Background
The load test of the motor is mostly carried out by dragging the tested motor by a dynamometer and outputting the load by the motor, the concentricity of the tested motor and the relative position of the dynamometer is required during the test, and particularly the concentricity of the motor with high rotating speed is required during the test. Whether the motor is installed on the end face or the motor is installed on the base, the current common centering mode in the industry is realized by detecting concentricity through a dial indicator or a laser centering instrument and continuously adjusting the position of the support or the base after the motor is installed on the support or the base.
Using conventional methods for centering, firstly the adjustment process may take a considerable amount of time, thus affecting the overall test progress, secondly the centering results are artificially very affected, and there may be a great variability in the centering results for the personnel of different operating experiences, and finally considerable costs may be incurred by means of high-precision centering equipment (e.g. a laser centering instrument).

Detailed Description
As shown in fig. 1, the centering-free motor mounting bracket of the end surface mounting motor testing system disclosed by the invention comprises a bracket body 4, wherein the bracket body comprises a bottom plate 41, and two parallel first mounting surfaces 42 and second mounting surfaces 43 which are vertically fixed on the bottom plate, and the first mounting surfaces 42 and the second mounting surfaces 43 are respectively provided with a first spigot 44 and a second spigot 45 which are concentric. The bracket body 4 is required to be finally formed by welding several steel plates and then finish machining, wherein the machining is required to ensure the parallelism of the first mounting surface 42 and the second mounting surface 43 and the perpendicularity of the first mounting surface and the second mounting surface and the bottom plate 41, and the concentricity of the first spigot 44 and the second spigot 45 is required to be ensured.
After the bracket body of fig. 1 is processed, the whole assembly is carried out as shown in fig. 2: during installation, the dynamometer 1 is connected with the dynamometer mounting plate 2 through a spigot or a locating pin, the dynamometer mounting plate 2 is connected with the dynamometer side expansion panel 3 through the spigot, and the dynamometer side expansion panel 3 is connected with the first mounting surface 42 through a first spigot 44. The tested motor 7 is connected and installed with the tested motor mounting plate 6 through a spigot or a locating pin, the tested motor mounting plate 6 is connected and installed with the tested side expansion panel 5 through the spigot, and the tested side expansion panel 5 is connected and installed with the second mounting surface through a second spigot 45.
