How is the casting base of inspection tool manufactured
Automobile inspection tool is a simple tool used by industrial enterprises to control various sizes of products, such as aperture, space size and so on. It can improve production efficiency and control quality. It is suitable for mass-produced products to replace professional measuring tools in auto parts, such as smooth plug gauge, thread plug gauge, outer diameter snap gauge, etc. So what are the factors that need to be considered in the design of automobile inspection tools?
Before the design and manufacture of automobile inspection fixture, the concept of inspection fixture design should be clarified. The main factors to be fully considered are: fully understand a descriptive document GD & T of automobile product design. Product specifications, product positioning datum, key product characteristics and product tolerance characteristics will be reflected in GD & T. therefore, it must be fully understood before the design of inspection fixture. 2. Determine the positioning and testing contents of products, analyze the positioning datum features of products, consider the best placement position of product parts, understand the meaning of various tolerances, and determine the testing contents that must be realized on the inspection fixture and those that do not need to be realized or even cannot be realized at all. 3. Statistics of process control capability, identify whether the product has KPC requirements, CNC precision manufacturing, understand the purpose of inspection tools, correctly understand the needs of quantitative measurement and qualitative measurement, and ensure the reliability of data acquisition. 4 understand the requirements and process, fully understand the customer’s demand for product inspection tools, learn from previous successful or failed cases, fully understand the customer inspection tool review and approval process, and understand the required documents.
The design principle of the pick-up shall have sufficient rigidity; It shall have sufficient stability; It shall have sufficient measurement accuracy to ensure vehicle quality; The operation shall be convenient to ensure sufficient measurement efficiency; The structure shall be as simple as possible; It shall have good appearance; It shall have sufficient economy to ensure easy control of vehicle cost; At the same time, it shall be convenient for measurement and calibration. The design points should have the commonness of auto parts inspection tools and their own characteristics. Its structure is mainly composed of the following parts: base plate and frame, positioning device, clamping device, measuring device, auxiliary device, etc.
