Tooling, fixtures, checking fixture design outline
1、The tooling, jigs and fixtures are designed to improve the efficiency of the batch production of mechanical products and ensure the quality stability of mechanical products, so as to achieve the purpose of reducing the production cost of products. Therefore, the design and manufacture of tooling, jigs and fixtures should unconditionally obey this purpose.
2, tooling, fixtures, inspection tools are generally single-piece, set production, but the use of time generally requires longer, mold-type tooling mainly consider the service life, maintenance conditions, etc.. Fixture class tooling mainly consider the ease of use, safety, efficiency and reliability. checking fixture mainly consider the convenience of use, reliability, convenient maintenance, etc.
3, in view of the above reasons tooling, fixtures, checking fixture design cost issues to give way to safety, efficiency, reliability, life, ease of use and other factors.
4, the design of the use of mature standard parts (such as guide pillars, guide bushings, fasteners, springs, hardware, cylinders, hydraulic cylinders, standard mold frame, quick collet, etc.).
5, the design of the main parts should be carefully designed metal materials and heat treatment types (such as: tempering, high frequency, carburizing quenching, nitriding quenching) matching and hardness selection, especially to take into account the prevention of deformation of the parts after heat treatment, mutual friction parts to consider the hardness matching and the necessary lubrication measures.
6, surface treatment according to the function of the parts carefully design the thickness and type of plating (galvanization, nickel plating, bright chrome plating, anodization, hard anodization, conductive anodization, hard chrome plating, blue, etc.).
