Detailed Description

In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below.

In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention, however, the present invention may be embodied in other specific forms than those described herein, and it will be apparent to those skilled in the art that the present invention may be practiced without departing from the spirit and scope of the present invention.

As shown in fig. 1: the fatigue testing device of the electric roller motor comprises a fixed base 1-1, wherein a locking device 1-3, a front end supporting seat 1-2 and a rear end supporting seat 1-4 are arranged on the fixed base 1-1; a bearing is arranged at the tail part of the rear end supporting seat 1-4, so that the motor can synchronously move with the rear end supporting seat when in operation, and a spring is arranged at the joint when the rear end supporting seat 1-4 is arranged with the fixed base 1-1, so that the rear end supporting seat 1-4 can automatically stretch out and draw back; the front end supporting seat 1-2 comprises a seat body 2-1, the seat body 2-1 is provided with an arc surface, the rear end supporting seat 1-4 is circular, and the arc surfaces of the two parts are required to be concentric when the positions of the front end supporting seat 1-2 and the rear end supporting seat 1-4 are required; as shown in fig. 2, a rubber-coated bearing 2-2 is arranged below the arc surface of the base body 2-1, and the rubber-coated bearing 2-2 is used for being fully attached to a rotor of a motor; as shown in figure 3, the locking device 1-3 is composed of a first fixing block 3-1 and a second fixing block 3-2 which are symmetrically arranged, a gap between the first fixing block 3-1 and the second fixing block 3-2 is used for clamping a stator part of the motor, and the first fixing block 3-1 and the second fixing block 3-2 are locked by a bolt 3-3, so that the motor can be smoothly locked on the device, the whole motor can be fixed and frequent tests can be carried out.

The working process of the utility model is as follows:

usually, when the motor rotates, in order to make the motor more completely simulate the working condition in actual use. As shown in fig. 2, when the motor operates, the rotor (i.e. the housing) of the motor is fully attached to the rubber-covered bearing 2-2, because the rubber-covered bearing has the characteristic of large friction force, the motor rotates to fully contact with the rubber-covered bearing 2-2, and the working condition that the electric roller is attached to the belt during operation is fully simulated.

Because of the structural characteristics of the outer rotor motor, a stator (namely, a motor shaft) needs to be fixed, and a locking device shown in fig. 3 is adopted through structural analysis and optimization of the motor mounted on the whole machine equipment. The first fixing block 3-1 and the second fixing block 3-2 are fixed on the fixing base 1-1, the locking position of the second fixing block 3-2 is drilled with threads, and a device locked by a bolt 3-3 is adopted to lock the stator part of the motor. The structural requirement of the product on the whole equipment is perfectly simulated.

Because the shape of the motor of the electric roller is longer, the motor is prevented from shaking when the motor rotates, and the testing effect of the motor is greatly influenced, and the rear end supporting seat 1-4 is added from the rear end to prevent the shaking when the motor rotates. When the rear end supporting seat 1-4 and the fixed base 1-1 are installed, the spring device is arranged, so that the rear end supporting seat 1-4 and the rear end part of the motor can be effectively attached, and the influence on the rotation of the motor caused by the friction between the rear end supporting seat 1-4 and the motor 1-5 when the motor rotates is avoided.

Under normal conditions, however, when the motor 1-5 rotates, the rear end support base 1-4 is driven by the rotation of the motor 1-5 through the attachment of the rear end support base 1-4 to the motor 1-5, and the customized rubber-coated bearing 2-2 is driven to rotate and increase the resistance of the motor 1-5; meanwhile, the locking device 1-3 locks the stator part through the bolt 3-3 so that the motor can run and test smoothly.

The utility model can be applied to a production line, and reduces the reject ratio of the motor by simulating the on-site working condition of the motor fixing die. Meanwhile, the cost is controlled, and meanwhile, the use of operators is facilitated.

The utility model has simple, compact and reasonable structure, and effectively tests the motor through a simple mechanical structure; meanwhile, the operation is convenient for operators to use, and the operation is simple and easy; meanwhile, the productivity and the qualification rate of the product assembly line are improved.

The present application provides a fatigue testing device for an electric roller motor, which is described in detail above, and the principle and the implementation of the present application are explained herein by applying specific examples, and the description of the above examples is only used to help understand the method and the core idea of the present application; meanwhile, for a person skilled in the art, according to the idea of the present application, there may be variations in the specific embodiments and the application scope, and in summary, the content of the present specification should not be construed as a limitation to the present application.
