Description

Technical Field

[0001] This utility model belongs to the technical field of massage mechanism testing equipment, specifically a functional testing device for mechanical massage mechanism components. Background Technology

[0002] With the rapid development of the massage equipment industry, mechanical massage mechanisms, as core components, contain one or more massage airbags, and their performance stability directly affects the product's effectiveness and user experience. Currently, the massage airbags in common massage mechanisms on the market typically have lifting and rotation functions, requiring dynamic testing under load conditions to verify whether their lifting height, number of rotations, and rotation speed meet design requirements. However, traditional testing methods have the following problems: 1) Insufficient load simulation: Most existing testing devices perform tests under no-load or static load conditions, failing to realistically simulate the stress conditions of the massage mechanism under actual working conditions, leading to deviations between test data and actual performance. 2) Incomplete data acquisition: Some testing equipment can only test lifting or rotation parameters individually, making it difficult to achieve simultaneous acquisition of multiple parameters under dynamic working conditions, reducing testing efficiency and reliability. Therefore, there is an urgent need for a testing device that can simulate real load conditions and simultaneously acquire lifting height and rotation angle data to improve the efficiency and accuracy of functional testing of massage mechanism components. Utility Model Content

[0003] The purpose of this invention is to provide a functional testing device for mechanical massage mechanism components. This device can test the lifting height, rotation number, and rotation speed of the massage airbags in the massage mechanism. Furthermore, the load weight can be flexibly adjusted by changing the number of counterweights, simulating the working state of the massage mechanism under different load conditions. It closely matches actual usage scenarios and can comprehensively obtain the core functional parameters of the massage mechanism. This solves the problem that traditional testing devices can only test from a single dimension and cannot take into account both rotation and lifting performance. The testing dimensions are more comprehensive, and the data is more valuable for reference.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A functional testing device for a mechanical massage mechanism component includes a worktable, several sets of load units arranged opposite each other, a mounting mold, a rotation measuring instrument, and a displacement measuring instrument. The worktable includes an upper plate, a lower plate, and several support columns; the upper and lower ends of the support columns are fixedly connected to the upper and lower plates, respectively. Each load unit includes a rotating shaft, a mounting plate, a stop block, and several counterweights; the lower end of the rotating shaft passes through the upper plate and is fixedly connected to the mounting plate; the stop block is mounted on the rotating shaft above the upper plate, and the counterweights are fitted onto the rotating shaft above the stop block; the load weight is adjusted by changing the number of counterweights. The mounting mold includes several upper molds and lower molds. The upper mold is installed at the lower end of the mounting plate, and the lower mold is installed on the lower plate. The lower end of the upper mold is provided with an upper mounting groove, and the upper end of the lower mold is provided with a lower mounting groove. The upper and lower ends of the massage mechanism are respectively embedded in the upper and lower mounting grooves. The massage airbag of the massage mechanism lifts or rotates, driving the rotating shaft to lift or rotate. The upper end of the rotating shaft is rotatably provided with a mounting rod. At least one rotation measuring instrument is provided on the mounting rod, and the measuring shaft of the rotation measuring instrument is connected to the rotating shaft. The rotation measuring instrument measures the number of rotations and the rotation speed of the rotating shaft. The upper plate above the mounting plate is provided with a displacement measuring instrument, which measures the lifting height of the mounting plate.

[0006] Furthermore, cylinders are fixed on both sides of the upper plate; the telescopic rod of the cylinder is located below the mounting rod, and the mounting rod is raised or lowered by the cylinder.

[0007] Furthermore, the mounting rod is detachably mounted on the upper end of the rotating shaft via a connector, and a bearing is provided at the corresponding position of the mounting rod and the rotating shaft; the connector includes a connecting block, a connecting protrusion, and a connecting screw; the connecting protrusion and the connecting screw are respectively fixed to the upper and lower ends of the connecting block; the upper end of the rotating shaft is provided with a mounting hole, and the connecting screw is threadedly connected to the mounting hole; the outer ring of the bearing is fixedly connected to the mounting rod, and the inner ring of the bearing is tightly clamped between the connecting block and the upper end of the rotating shaft; the connecting protrusion is connected to the measuring shaft of the rotary measuring instrument.

[0008] Furthermore, a bracket is detachably mounted on the mounting rod via screws; the rotary measuring instrument is fixed on the bracket; a connecting hole is provided on the measuring shaft of the rotary measuring instrument, and the upper end of the connecting protrusion is tightly embedded in the connecting hole, thereby driving the measuring shaft of the rotary measuring instrument to rotate through the connecting protrusion.

[0009] Furthermore, the rotary measuring instrument is a rotary encoder, model Omron E6B2-CWZ6C; the displacement measuring instrument is a laser displacement sensor, model Panasonic HG-C1200.

[0010] Furthermore, both the upper and lower molds are detachably mounted to the mounting plate and the lower plate respectively using screws.

[0011] Furthermore, the number of load units is two; the number of upper molds is two, and the number of lower molds is one.

[0012] After adopting the above technical solution, the present invention has the following beneficial effects:

[0013] 1. This utility model discloses a functional testing device for a mechanical massage mechanism component. In use, the upper and lower ends of the massage mechanism are first embedded into the upper and lower mounting slots, respectively. Then, the massage mechanism is activated, causing the massage airbags to begin lifting and rotating. During this process, a displacement measuring instrument can be used to measure the lifting height of the massage airbags relative to the mounting plate in real time, thus detecting the lifting height of the massage airbags. Simultaneously, a rotation measuring instrument connected to the rotating shaft can accurately measure the number of rotations and rotation speed of the rotating shaft, thus detecting the number of rotations and rotation speed of the massage airbags. Furthermore, the load unit, through the cooperation of the rotating shaft, mounting plate, stop, and counterweight, allows for flexible adjustment of the load weight by changing the number of counterweights. This simulates the working state of the massage mechanism under different load conditions, closely matching actual usage scenarios. It comprehensively acquires the core functional parameters of the massage mechanism, solving the problem that traditional testing devices can only detect a single dimension and cannot simultaneously consider rotation and lifting performance. The testing dimensions are more comprehensive, and the data is more valuable for reference.

[0014] 2. This utility model discloses a functional testing device for a mechanical massage mechanism component. The telescopic rod of the cylinder is located below the mounting rod. The cylinder drives the mounting rod to rise or fall. That is, when installing a massage mechanism with testing function, the cylinder can drive the mounting rod to rise, thereby driving the upper mold to rise, so that the lower end of the massage mechanism can be placed into the lower mounting slot. When the cylinder retracts, the mounting rod drives the upper mold to fall under the action of gravity, so that the upper end of the massage mechanism can be placed into the upper mounting slot, thus realizing the quick installation or removal of the massage mechanism.

[0015] 3. This utility model provides a functional testing device for mechanical massage mechanism components. The device is designed with full consideration of adaptability, and many key components are designed to be detachable or adjustable, which improves the adaptability of the test and meets diverse testing needs. On the one hand, the upper mold of the mounting mold can be detachably installed on the mounting plate with screws, and the lower mold can be detachably installed on the lower plate with screws. When different models and sizes of massage mechanisms need to be tested, only the upper and lower molds of the corresponding specifications need to be replaced, without replacing the entire testing device, which greatly reduces the equipment replacement cost. On the other hand, the load weight of the load unit can be adjusted by the number of counterweights, which can be flexibly adjusted according to the load requirements of different massage mechanisms, and can be adapted to both low-load and high-load testing scenarios. In addition, the mounting rod can be detachably mounted with screws, and the rotary measuring instrument is fixed on the bracket. If it is necessary to replace the rotary measuring instrument with a different precision or model, the bracket can be easily removed to complete the replacement. Moreover, if the massage airbags of the massage mechanism rotate synchronously, the number of rotations and the rotation speed of each massage airbag are the same, and only one rotary measuring instrument needs to be installed. If the massage airbags do not rotate synchronously, multiple rotary measuring instruments can be installed to measure separately, which further expands the testing adaptability of the device and meets the testing needs of massage mechanisms of different specifications and different testing standards.

[0016] 4. This utility model discloses a functional testing device for a mechanical massage mechanism component. It can utilize an Omron E6B2-CWZ6C rotary encoder as a rotation measuring instrument and a Panasonic HG-C1200 laser displacement sensor (displacement measuring instrument). Both components are mature and high-precision measurement products in the industry. The Omron E6B2-CWZ6C rotary encoder features high resolution and high response speed, accurately measuring the number of rotations and rotation speed of the shaft, avoiding deviations in speed and rotation count data caused by insufficient precision of the measuring components. The Panasonic HG-C1200 laser displacement sensor employs laser detection technology, offering high measurement accuracy and strong anti-interference capabilities. It can accurately capture the lifting height of the mounting plate in real time, ensuring the reliability of the massage mechanism lifting performance test data. Attached Figure Description
