[0002] After the automotive generator is assembled, it is necessary to conduct a factory performance test. During the test, the motor needs to be fixed on the test bench. Most traditional methods use a clamping method to fix the motor, that is, a nut is used to lock the pressure plate, and the outer edge of the motor is pressed with the pressure plate to fix the motor. This method is cumbersome to operate, and there is a problem that the motor is not firmly fixed. In the prior art, although there is a fixing method that uses a support rod to connect the hanging ear or the motor mounting hole, due to the different distances between the mounting holes of the motor housing of different models, each model corresponds to a test fixture, resulting in a waste of materials, and each test of a motor requires time to find the corresponding test fixture, which reduces efficiency. Therefore, it is necessary to improve the existing test fixture. Summary of the invention

[0022] In the description of the invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the invention can be understood according to specific circumstances.

[0023] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0024] A generator test tool, such as Figures 1 to 4 As shown, it includes a base 1 and several fixing mechanisms 2 on the base, and the base is provided with several fixing holes 3. Preferably, the fixing holes are countersunk holes. The fixing mechanism includes a fixing seat 4, and a support column 5 is detachably installed on the fixing seat. Several support column mounting holes 6 for mounting support columns configured for different types of generators are provided on the upper surface of the fixing seat. As an example, 3-5 mounting holes are provided on the upper surface of the fixing seat.

[0025] The support column includes a main body 7, a mounting portion 8 is provided at the lower end of the main body, the mounting portion is installed in the mounting hole, the diameter of the mounting portion is smaller than the main body, and a positioning platform 10 is formed at the junction of the two; a connecting portion 11 is provided at the upper end of the main body, and a support platform 12 is provided at the position of the main body under the connecting portion, and a screwing operation portion 13 is provided at the position of the main body under the support platform; the mounting portion adopts a columnar structure, which is inserted into the mounting hole and slides with the mounting hole. As an example, the screwing operation portion includes several milling planes on the outer circumference of the main body. The connecting portion is provided with an external thread structure.

[0026] When in use, according to the specifications of the generator to be tested (i.e. the distance between the casing mounting holes), adjust the position of the support column of the fixing mechanism (i.e., install the support column in the corresponding support column mounting hole), then align the generator mounting hole with each support column, use a wrench to screw the support column with the aid of the screwing operation part, and connect and fix the connecting part of the support column to the mounting hole of the generator casing. The support table serves as a limiting structure. After the connecting part of the support column is screwed into the mounting hole of the casing, the support table can support the surface of the column casing, thereby stably fixing the generator to be tested on the tooling. Compared with the method of fixing with bolts to tighten the pressure plate, it is more convenient, simplifies the operation, and saves time and effort.

[0027] In an optional embodiment, a mounting groove 14 is provided on the base corresponding to each fixing seat, and the fixing seat can be detachably installed in the mounting groove. A limiting column 15 is provided at the lower end of the fixing seat, and a limiting hole cooperating with the limiting column is provided in the mounting groove. The fixing seat cooperates with the mounting groove, and the limiting column cooperates with the limiting hole of the mounting groove, thereby ensuring a stable matching relationship between the fixing mechanism and the base. A handle 9 extending outward from the base is provided on one side of the fixing seat away from the center of the base, so as to facilitate the placement and removal of the fixing mechanism. In this scheme, the number and position of the fixing mechanism can be configured on the base as needed, which has strong adaptability and better versatility.

[0028] The base created by the present invention is provided with a fixing mechanism for fixing the generator to be tested, which can be conveniently connected to the mounting hole of the generator to ensure the stability of the generator structure during the test. At the same time, the fixing mechanism can be adapted to generators of various specifications, has good versatility, does not require excessive adjustments when installing and fixing the generator, is simple to operate, and has high test efficiency.

[0029] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
