Description

Technical Field

[0001] The utility model belongs to the technical field of teaching instruments, and particularly relates to a comprehensive training platform for mechanical fault diagnosis. Background Art

[0002] The diagnosis technology of mechanical faults is widely used in large-scale equipment in industrial sites. Most of them use traditional instruments for detection or human experience for judgment. There is still a big gap between the development forms of industrial sites in China and those in the international arena. The use of advanced instruments should be popularized to enhance the overall strength of the industrial equipment team and provide strong support for the national strategic development. At present, most of the existing mechanical fault diagnosis platforms on the market adopt a fixed mechanical transmission mode. The fault diagnosis methods are relatively traditional and backward, the fault forms are single, and they cannot prevent and respond to the changing mechanical faults in industrial sites in a timely manner. To ensure the normal operation of large-scale equipment, preventive maintenance is particularly crucial. Currently, when carrying out training in enterprises or schools, there is a lack of integration of modern detection means and a lack of a comprehensive, targeted, and intelligent mechanical fault platform that fits the industrial scenario for training or teaching. Therefore, in view of the functions required by the current social development situation, a mechanical fault intelligent diagnosis comprehensive training platform has been developed specifically.

[0003] Chinese patent document with the publication number CN115662227A discloses a training platform for vocational skill appraisal in the field of mechatronics and hydraulics maintenance. In this platform, a training area and training modules are set in a test bench. Each training area and training module is divided into three parts: mechanical, hydraulic, and electrical. Corresponding devices are set in each part. The provided training platform for vocational skill appraisal in the field of mechatronics and hydraulics maintenance can support three types of training projects: mechanical, hydraulic, and electrical in the equipment, and can realize the process training of testing, diagnosing, repairing, assembling, and debugging the faults of mechatronics and hydraulics equipment. Each functional module of the training platform for diagnosing and repairing the faults of mechatronics and hydraulics equipment realizes the visualization of the training process and results based on sensors and related software, and feeds back the training results, which can improve the pertinence and effectiveness of the training.

[0004] In the above patent solution, the combination installation of each hardware device is carried out by relying on the T-shaped grooves on the installation platform. However, in actual applications, there are many types of hardware devices, and for some hardware devices, such as between the motor and the speed reducer, there are also strict requirements for coaxiality. Reducing the distance between adjacent T-shaped grooves to adapt to various hardware devices will inevitably cause a decrease in the structural strength of the installation platform, and the mechanical vibration generated by the operation of devices such as motors will surely cause structural damage; without reducing the distance, the applicable range of hardware devices will be reduced, and it will not be able to meet the refined adjustment between devices, such as the high-precision requirement of coaxiality. Content of the Utility Model

[0005] In order to overcome the technical problems in the prior art that the degree of freedom of the installation position on the assembly platform is relatively low, it cannot adapt to a variety of hardware devices, and fine adjustment cannot be carried out between hardware settings; an object of the present utility model is to provide a comprehensive training platform for mechanical fault diagnosis. By arranging threaded holes in an array on the assembly platform, an upper mounting plate and a lower mounting plate with mutually perpendicular sliding directions are used for installation, providing a high degree of freedom for the installation of hardware devices. At the same time, an adjusting screw for driving the sliding of the upper mounting plate is threadedly connected to the lower mounting plate to achieve precise fine adjustment of the position of the hardware device.

[0006] In order to achieve the above object, the present utility model is implemented by adopting the following technical solutions: A comprehensive training platform for mechanical fault diagnosis includes an assembly platform, and a plurality of fixing parts are detachably connected to the upper end of the assembly platform.

The rotation axis direction of the hardware device is parallel to the length direction of the transverse groove; fastening screws, the fastening screws include a plurality of first screws passing through the transverse grooves and screwed into the threaded holes and a plurality of second screws passing through the longitudinal grooves and screwed onto the lower mounting plate; wherein, the fixing parts further include a plurality of adjusting screws slidably connected to the lower mounting plate along the length direction of the longitudinal groove; the adjusting screws are in transmission connection with the upper mounting plate; a plurality of internal threaded holes respectively in transmission connection with the adjusting screws are arranged on the lower mounting plate; the adjusting screws are rotatably connected in the corresponding internal threaded holes.

[0007] By rotating the adjusting screw, the adjusting screw pushes the upper mounting plate to slide horizontally, that is, drives the hardware device to slide along the radial direction of its rotation axis. The cooperation of the adjusting screw and the internal threaded hole magnifies the adjustment distance of the upper mounting plate, and thus the position of the hardware device can be precisely fine-tuned; with the corresponding coaxiality detection device, the coaxiality between two adjacent hardware devices can be conveniently adjusted.
