Publisher: Administrator Date:2021-07-07
The standard parts of the inspection tool are also called standard parts, which refer to the thorough specifications and standardization of layout, drawing, symbols and dimensions, and some commonly used parts and components produced by professional manufacturers, such as rolling bearings, keys, and threaded parts. , Sales, etc. In a broad sense, it includes standardized seals, tension springs, connectors, hydraulic components, fasteners, bearings and other mechanical parts. In a narrow sense, it only includes standardized fasteners. The domestically known standard parts (standard parts for inspection tools) are the abbreviations for standard fasteners. They are a narrow concept and cannot eliminate the existence of broad concepts. In addition, there are professional standard parts, such as standard parts for automobile inspection tools. , Mold standard parts, etc., also belong to the broad sense of standard parts.
In a broad sense, specification parts are mechanical parts (parts) and components with clear specifications. The application specifications mainly include the Chinese National Code (GB), the American Society of Mechanical Engineers (ANSI/ASME), etc., and other Japanese (JIS) and German (DIN) and other standards are also widely used in the world. Mechanical parts and components with a high degree of standardization and strong occupational versatility are also called general-purpose parts. The general specification parts include fasteners, connectors, transmission parts, seals, hydraulic components, pneumatic components, bearings, tension springs, etc., all have corresponding national specifications, and they have strong cross-professional versatility. Professional norms, this concept is attributed to the conventions in the professional world, and there is no clear stipulation. Occupational standard parts commonly include mold standard parts, automobile standard parts and so on. When a commodity is widely used in occupations, it is a universal piece; the norms for universal pieces are generally formulated by the leading companies of the professional circles and are widely accepted by the professional circles. In this way, the company norms become the de facto professional norms, which can also be called occupations. Standardize the pieces. Mold standard parts, the current degree of professional standardization of molds is relatively high, including injection mold bases, push rod push tubes, warm runner molds, etc. in detail.
There are currently a wide variety of automotive inspection tool specifications, such as automotive fasteners, spark plugs, shock absorbers, and door locks. For details, see (Automotive Specifications Manual). The more sophisticated the industry, the higher the degree of standardization and standardization, the more standard parts, and the lower the cost of the profession. Therefore, it is necessary to prevent excessive standardization and standardization to avoid monotonous and low-end industry varieties.
