Abstract

The invention provides a flexible fixture, particularly a flexible fixture for precisely measuring three-coordinate of a sedan part. The flexible fixture is designed for solving the problems in the field of automobile manufacture, such as comparatively poor generality and rigidity, large possibilities of being deformed and introducing additional errors and so on when precisely measuring a special-shaped complex part in bearing, positioning and clamping, particularly in sedan manufacturers. The flexible fixture is a combined fixture of grooves and holes, which is composed of a series of standardized parts and has very high flexibility of clamping; and rapid clamping and positioning of the complex sedan part are achieved by the lifting of a thread connection system and the sliding of a sliding block in a lead groove with assistance of precise measuring and positioning of the three-coordinate. The invention fully exerts the characteristics of in-place bearing, reliable positioning, rapid clamping, eliminated deformation error and spring-back and high measurement precision, meets the requirement for precisely measuring the three-coordinate of the sedan part and plays an important role in quality control over the complex sedan part.

Description

Three-coordinate precise measuring flexible clamper of car element

Technical field

In the automobile production field, especially in car manufacturer, for guaranteeing the quality of product, need be many to those kinds with three coordinate measuring machine, complex contour, inside gadget not of uniform size, stamping parts, and parts such as weldment are measured, traditional method is before part of measurement, at first according to measurement requirement, formulate various location and clamping scheme, manufacture and design special-purpose detection support, according to existing plan, on the work top of three coordinate measuring machine, these location and clamp device are built then, can measure after setting up measurement coordinate system on this basis, this way is difficult to adapt to the needs of modernized large-scale production.The measured thin-wall part in automobile production field is generally formed by technologies such as injection mo(u)lding, punching press, welding, and two characteristics are generally arranged: shape more complicated, irregular, so supporting, location, clamping are all cumbersome; Its two rigidity is poor, yielding, is easy to introduce additive error.Use the flexible clamping system just very important in this case.

When carrying out car parts three-coordinate precise measuring, we often find that a lot of unit clamps do not possess the needed versatility of daily testing.On the other hand, built-up jig is best suited in short run or non-repeatability production, parts three-coordinate precise measuring clamping location.Built-up jig or other Flexible Fixturing system, not only clamp accurately, reliable, and can solve distortion inaccuracy and the low problem of resilience measuring accuracy preferably.

Background technology

Automobile is an epitome of modern civilization society, auto manufacturing possess skills dense degree height, big, the comprehensive strong feature of production lot, and in the national economy of any one major industrialized country, it all occupies critical role.In recent years, the Chinese automobile manufacturing industry has obtained tremendous development, but the development ability of entire car and key components and parts is very low, and quality also lags far behind developed country's level.The workmanship of auto parts and components is the key factors that improve product competitiveness, has only and makes great efforts to improve its workmanship in the short period of time, could win victory in intense market competition.Digital Measuring Technique is one of gordian technique in the digitizing manufacturing technology.Make three-coordinate precise measuring integrated, incorporate machining tool and manufacturing system, form advanced digitizing closed loop manufacturing system, be the development trend of current Technology of Precision Measurement.Good quality control is a factor that successful enterprise is indispensable, and three-coordinate precise measuring is the sign of an enterprise-quality controlling level.Along with developing of automobile industry, the quality assurance means are paid attention to by increasing automaker, and three-coordinate precise measuring with it efficiently, advantage is being brought into play more and more important effect aspect the quality control of automobile accurately.

Summary of the invention

The present invention is the slotted eye built-up jig that the series of standards parts are combined into, it has very high clamping flexibility, be aided with three-coordinate precise measuring location, the accurate clamping to the car parts is finished in lifting by the system of being threaded and the slip of slide block in the helical pitch groove.In the three-coordinate precise measuring of reply car parts, more can give full play to its location reliable, clamp fast, distortion inaccuracy is little, measuring accuracy is high, assemble characteristics fast and accurately.Satisfy the requirement of car parts three-coordinate precise measuring, for car parts flexibility measurement provides a kind of new way, for enterprise's product materialization development has been explored new approaches with information system management.
