Description

A kind of car door single-piece cubing

Technical field

The present invention designs a kind of cubing, is specifically related to a kind of car door single-piece cubing.

Background technology

Coordinate measuring machine is a kind of geometric measurement instrument; Its ultimate principle is that tested part is put into the measurement space that it is allowed; Critically measure the numerical value of tested part at X, Y, three coordinate positions of Z, handle through computer data according to the numerical value of these points, match forms measures element; Like circle, ball, cylinder, circular cone, curved surface etc., draw shape, position of related features and other geometric sense data through mathematical computations.

The problems of measurement of using coordinate measuring machine to overcome a difficulty is increased work efficiency, and saves the manufacturing of unit clamp, stores work such as maintenance.Coordinate measuring machine divides from version, mainly is divided into bridge-type, cantilevered, horizontal arm and planer-type (also claiming gantry type).Bridge type coordinate measuring machine is to use maximum a kind of machines, is used in medium measurement space, and precision is high.Along with the raising of measuring machine automaticity, in small size is measured, use very extensively.The cantilevered measuring machine: this structural rigidity is good, and is easy to operate, and measuring accuracy is high, is the canonical form of the measuring machine of little measurement space.Horizontal arm type measuring machine: the canonical form that is wide-measuring range, low precision coordinate measuring machine.But its operating performance is fine, because its moving mass is little, thereby very quick.Often the measuring machine of this form in being called " robot measurement ".The planer-type measuring machine: be the ultra-large type machine, the transverse axis maximum can arrive tens of rice, because its rigidity is more much better than horizontal arm type, thereby large scale is had enough precision.But coordinate measuring machine is very high to the requirement of working environment, and the cost of its manufacturing simultaneously is also expensive.

One Chinese patent application number: 201020691319.0 1 kinds of automotive door assembly cubings; File discloses a kind of automotive door assembly cubing; Comprise fixed support and be fixed on the hinge detection module on the fixed support that described hinge detection module comprises upper hinge module and following hinge module; Described upper hinge module comprises first holder and first web joint hinged with first holder; Described hinge module down comprises second holder and second web joint hinged with second holder.The automotive door assembly cubing of the utility model, cubing is simple in structure, and the folding matching that can be used for four of vehicle body movable parts detects, but the precision of its detection and duplicate measurements aspect can also improve.

Summary of the invention

The technical matters that invention will solve

To the problem of traditional three-dimensional coordinates measurement workpiece existence and the shortcoming of common cubing existence, the present invention provides a kind of car door single-piece cubing, can realize making things convenient for the duplicate measurements workpiece through the present invention, reduces cost, and accuracy of detection is strengthened greatly, has improved efficiency of measurement.

Technical scheme

A kind of car door single-piece cubing comprises base plate, block, rotating mechanism, clamp, cubing body, locating surface, inspection pin, section rule, Building L, register pin; Base plate is provided with the cubing body, and cubing body top is equipped with register pin, and it can locate workpiece fast, and wherein the inspection pin is positioned on the cubing body, measures the size in aperture.Be provided with block around the cubing body, prevent that workpiece from sliding, wherein the quantity of block is 9.Rotating mechanism is through on the fixed base plate of Building L.Clamp is fixed on the Building L and is connected on the base plate, firm workpiece further, and the mode that wherein mainly contains locating surface and chuck clamping and positioning is located workpiece.Three groups are detected the use that closely cooperates, and the both sides of clamp are provided with section rule, can accurately detection faces difference situation.

Base plate is processed by steel or iron square tube; Block is processed by the 45# steel; Rotating mechanism is processed by 45# steel and aviation aluminium, and section rule are formed through digital control processing by 45# steel and aviation aluminium, and the cubing body is processed by high hardness resin; And each high precision cubing (quenching HRC45-50, handle and test section all are close-fitting) of forming through the inspection pin of heat treatment process.

Beneficial effect

(1) through clamp and block can the Rapid Realization workpiece the location, improve the efficient of work;

(2) through the use of logical no-go gage, the piece test precision is higher, can practice thrift cost greatly, and is the running time, convenient and swift;

(3) conveniently whether testing product is qualified for this product, and detection efficiency is high, and the maintaining expense is lower, realizes the online part of measuring at any time, reduces cost greatly, and quality testing is timely with feedback;

(4) save a large amount of running times, make things convenient for duplicate measurements, the cost aspect also has advantage, effectively improves workpiece stability.
