Embodiment Construction
[0010] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0011] The present invention provides a remanufactured parts assembly size classification matching method, which is used for combining and assembling the first type of remanufactured parts and the second type of remanufactured parts. According to the classification and matching method of remanufactured parts assembly size of the present invention, tolerance relaxation can be realized: if, the assembly size tolerance of the first type of remanufactured parts X The assembly dimensional tolerance of the second type of remanufactured part Y And the assembly dimension tolerance of the first type of n...

The invention discloses a mounting dimension classification matching method for reproducing components. The mounting dimension classification matching method is used for combined assembling of the reproducing components of a first type and the reproducing components of a second type. The method comprises the following steps that classification is carried out; the mounting dimensional tolerances, namely Xpsixi and Yzetaupsilon, between the reproducing components X and the reproducing components Y are translated to X-alphaalpha and Y-betabeta, wherein 2*alpha=xi-psi, alpha>0, 2*beta=upsilon-zeta, and beta>0; then the reproducing components X and the reproducing components Y are respectively classified to be X0+alpha, X-alpha0, Y0+beta and Y-betaalpha and matched; if the mounting dimensions of the reproducing components X and the mounting dimensions of the reproducing components Y are added to be combined and assembled, classification matching combinations are (X0+alpha, Y-betao) and (X-alpha0, Y0+beta), and if the mounting dimensions of reproducing components X and the mounting dimensions of the reproducing component Y are subtracted to be combined and assembled, the classification matching combinations are (X0+alpha, Y0+beta) and (X-alpha0, Y-betao). The method can effectively reduce assembling deviation, improves the quality of products, reduces reproducing product repair cost, and promotes the satisfaction degree of customers.
Description
technical field [0001] The invention relates to a graded matching method for remanufacturing of complex mechanical products, in particular to a graded matching method for remanufacturing parts assembly under uncertain conditions. Background technique [0002] The continuous progress of science and technology has led to the acceleration of product replacement, fierce market competition and personalized consumption, making the product life cycle shorter and shorter, and the amount of product waste caused by various reasons is increasing. In order to effectively coordinate the relationship between economic development and environmental protection, countries around the world have successively issued a series of laws, regulations and policies to manage, guide and supervise various industries, so as to achieve sustainable social development. Under the pressure of environment, resources, law and economic interests, remanufacturing has become a development trend of manufacturing ent...
