Description

Technical Field

[0001] The utility model belongs to the technical field of sprocket engagement detection, in particular to a trial platform for sprocket engagement detection. Background Art

[0002] The test platform for sprocket engagement detection is a device specially used to evaluate the meshing performance between sprockets and chains. It is widely used in the fields of mechanical engineering and automation to ensure that the design, manufacture and maintenance of sprocket systems meet technical and safety standards. The platform usually includes an adjustable bracket, an electric or manual drive system, and sensing technology for collecting data, such as mechanical sensors and high-speed cameras. By simulating actual working conditions, this platform helps engineers evaluate the fit between sprockets and chains and detect potential wear or tooth skipping problems, which plays an important role in improving product reliability and performance. With technological advances, such platforms have continued to improve in accuracy and automation, driving the development of related industries.

[0003] During use, the existing test platform may only test a certain type of sprocket set, which greatly limits its scope of application. For users who need to test multiple types of sprockets, this means that they need to purchase multiple sets of equipment or frequently replace accessories, which not only increases costs but also increases operational complexity. At the same time, in industrial applications, the models and specifications of mechanical parts often need to be adjusted and optimized according to actual needs. A platform that can only test a specific type of sprocket lacks flexibility and is difficult to adapt to rapidly changing production needs.

[0004] To this end, the utility model provides a trial platform for sprocket engagement detection. Utility Model Content

[0005] In order to make up for the shortcomings of the prior art and solve the problem that only a certain type of sprocket set is tested, which greatly limits its scope of application, the utility model proposes a trial platform for sprocket engagement testing.

[0006] The technical solution adopted by the utility model to solve its technical problems is as follows: a trial platform for sprocket engagement detection described in the utility model comprises a bottom plate, the inner side of the bottom plate is fixedly connected with left and right relative limit frames, the left top end of the bottom plate is fixedly connected with a first motor, the output end of the first motor is fixedly connected with a bidirectional lead screw, the bidirectional lead screw is rotatably connected with the right limit frame, the outer side of the middle end of the bidirectional lead screw is threadedly connected with left and right relative threaded sleeves, the outer side of the threaded sleeve is fixedly connected with a fixed frame, the inner side of the bottom plate is fixedly connected with front and rear relative slide rails, the top end of the slide rails is slidably connected with left and right relative sliders, the slider is fixedly connected with the fixed frame, a limited position assembly is arranged at the top end of the left fixed frame, a second motor is fixedly connected to the top side of the front end of the right fixed frame, a fixed assembly is arranged at the rear side of the second motor, and a limited position assembly is arranged at the rear top end of the right fixed frame at the same time;

[0007] Through the above technical solution, the first motor uses the bidirectional lead screw and the threaded sleeve to simultaneously drive the fixed frame to move in opposite directions, so that when detecting sprocket groups of different lengths, the position of the limit assembly and the fixed assembly can be quickly adjusted.

[0008] Furthermore, the limiting assembly includes a second electric push rod, the second electric push rod is fixedly connected to the rear side of the top end of the fixing frame, and the output end of the second electric push rod is rotatably connected to the limiting sleeve;

[0009] Through the above technical solution, the limiting sleeve is driven to move forward and backward by the second electric push rod, thereby facilitating the limiting of the two ends of the sprocket.

[0010] Further, the fixing assembly includes a fixing rod, the output end of the second motor is fixedly connected to a fixing sleeve, the rear inner end of the fixing sleeve is fixedly connected to a uniformly distributed connecting rod, the inner side of the connecting rod is fixedly connected to a limit plate, the middle side of the front end of the limit plate is fixedly connected to a fixing rod, the outer side of the front end of the fixing rod is rotatably connected to a first electric push rod, the output end of the first electric push rod is rotatably connected to a fixing arm, and the middle end of the fixing arm is rotatably connected to the limit plate;

[0011] Through the above technical solution, the first electric push rod itself is extended and retracted, thereby using the front end of the fixed rod as a stress point to drive the fixed arm to rotate, so that the front end of the sprocket can be quickly fixed, and the sprocket can be driven to rotate by the second motor using the fixing component.

[0012] Furthermore, an indicator block is fixedly connected to the front outer wall of the slider, and the front end of the indicator block is located on the center line of the limiting sleeve;

[0013] Through the above technical solution, the indicating block is arranged to move synchronously with the fixing frame.

[0014] Furthermore, a scale is fixedly connected to the front side of the top end of the bottom plate, and the scale is slidably connected to the indicator block;

[0015] Through the above technical solution, the indicator block is driven to move left and right by the fixed frame, so that the length of the transmission chain can be quickly understood through the cooperation between the indicator block and the scale, and the appropriate chain length can be quickly and intuitively determined, so that the test platform can be set up and adjusted more quickly, the test preparation time can be reduced, and the overall work efficiency can be improved.

[0016] Furthermore, a laser rangefinder is fixedly connected to the top end of the middle side of the fixing frame on the right side;

[0017] Through the above technical solution, a measurement system is formed by using a laser distance meter, an indicator block and a ruler. While it is convenient for the operator to quickly understand the data, the laser distance meter can also accurately measure the length of the sprocket under inspection to minimize the error.

[0018] The beneficial effects of the utility model are as follows:

[0019] 1. The utility model discloses a trial platform for sprocket engagement detection. The first motor utilizes a bidirectional lead screw and a threaded sleeve to simultaneously drive a fixed frame to move in opposite directions. Thus, when detecting sprocket groups of different lengths, the position of the limit assembly and the fixed assembly can be quickly adjusted. This makes it suitable for transmission chains of different lengths and specifications, providing users with a wider range of applications and increasing the versatility and flexibility of the test equipment.

[0020] 2. The utility model discloses a trial platform for sprocket engagement detection, which can quickly understand the length data of the sprocket through the indicator block and the ruler, and can accurately measure the data by cooperating with the laser rangefinder, so that the sprocket length can be measured automatically, which can greatly reduce the time and labor cost required for manual measurement and improve the efficiency of the entire detection process.
