[0002] In the field of fitness equipment manufacturing, left-right symmetry structure is a widely adopted design form, commonly found in strength training equipment, aerobic exercise equipment and multifunctional fitness equipment products. Such equipment usually requires balanced structure to ensure that users can experience stable force during training, while avoiding discomfort or potential safety hazards caused by structural deviation. For example, in barbell racks, gantry frames, multifunctional training devices, elliptical machines and rowing machines, the precision of symmetrical structure directly affects the stability and durability of the equipment, and thus the training effect and user experience.

[0003] However, during the production process of fitness equipment, due to factors such as material processing errors, welding deformation, assembly tolerances, fixture positioning errors and manual operations, the size and shape of left-right symmetrical components may not be consistent. This inconsistency may manifest as different left and right heights of supports, training arm angle deviation, connection part misplacement, and asymmetric slide rails, leading to uneven force during equipment use, and even causing structural deformation or abnormal wear, affecting the long-term service life and safety of the equipment. In addition, the fitness equipment industry has high requirements for product appearance, and the consistency of left-right symmetrical structure not only affects the functionality of the equipment, but also directly affects market competitiveness. For high-end fitness equipment brands, even minor structural deviations may result in products failing to meet strict quality standards, increasing rework rates and production costs.

[0004] To ensure the symmetry of fitness equipment meets design standards, precise measurement and detection of symmetrical components are required during production and manufacturing. However, due to the large size of fitness equipment and the need for detection after welding, bending or assembly, traditional measurement methods cannot meet the high-efficiency and precise detection requirements. Therefore, it is particularly necessary to develop a left-right symmetry structure consistency inspection fixing device.

[0005] In the context of the growing development of the fitness equipment industry, the market demand for high-quality, precise fitness equipment is increasing, and fitness equipment manufacturing enterprises face higher quality control requirements. The left-right symmetry structure consistency inspection fixing device can effectively solve the problem of symmetrical component consistency detection, provide precise and efficient detection tools for enterprises, optimize production processes, reduce defective product rates, and improve product market competitiveness. Therefore, developing a left-right symmetry structure consistency inspection fixing device that can adapt to different specifications of fitness equipment symmetrical components, is convenient to operate and measure accurately, has important practical significance for fitness equipment manufacturing enterprises.
