Description

Portable Three-Coordinate Measuring Arm original point position device
Technical field
The utility model relates to mechanical measurement technique, relates to portable Three-Coordinate Measuring Arm original point position device.
Background technique
Portable Three-Coordinate Measuring Arm is a high-tech mechanical gage of new generation, the similar GPS navigation system of its surveying work principle, owing to be provided with temperature compensation system in the arm, with fixed three coordinate measuring machine overcritical different to environment, it can use under various working environments, after the 3 d space coordinate reference point that configures measurand is initial point, adopt 3 d space coordinate localization method point to touch relevant serial measuring point with its probe, after compiling the each point coordinate parameters, but determine the surface evenness of arbitrary shape workpiece with the software kit accurate Calculation, the concentricity in multiaxis hole and circularity, the parameter that traditional mechanical amount instrument such as the relative space position degree of geometric element are difficult to measure.Raising workpiece machining quality level, mechanical product quality detection level there is important effect.
Be to guarantee measuring accuracy, the most basic, most crucial steps measure exactly before accurately location survey and guarantee in follow-up measuring phase stability (survey certain hour then must resume classes initial point) with reference to initial point with reference to initial point.
The positioning device with reference to initial point of prior art is such: as shown in Figure 1, the supporting positioning seat that has an integral body to be " L " piece shape of gage beam, the vertical piece 3 end end faces of " L " shape piece are provided with a cylindrical body pawl seat 2, the inner side surface that pawl seat 2 end faces are provided with by 1, three pawl of three claw type positioning pawls of circumference uniform distribution all is partial sphere shape concave arc surfaces suitable with probe; Be provided with one and half long-round-shape fixed gap 11 between 10 top and bottom of piece anyhow of " L " shape piece.Timing signal passes through fixed gap 11 usefulness bolton on thick and heavy stable weight with positioning seat, leans at the hemisphere concave arc surface with probe and demarcates.
Adopt such technology certainly to realize original point position, but also have following not enough: use in the laboratory in this way, thick and heavy worktable certainly is set, default corresponding with bolt screw comes fastening on platform then, but gage beam often is to use at the scene under plant environment, as engineering machinery, vehicle etc. is measured, the worktable that the Chang Wufa provisional configuration is thick and heavy, can only be fixed on the thick and heavy measurand, normally can not carry out destructiveness and open screw measurand, the fastening effect of positioning seat is bad, influences data veracity.
The model utility content
For overcoming the deficiencies in the prior art, it is a kind of when industry spot is used that the utility model provides, and can make things convenient for the portable Three-Coordinate Measuring Arm original point position device of stably demarcating initial point.
The utility model is to reach the technological scheme that above-mentioned technical purpose adopts to be: portable Three-Coordinate Measuring Arm original point position device, comprise positioning seat, the positioning seat top end is provided with a cylindrical body pawl seat, pawl seat end face is provided with three claw type positioning pawls by circumference uniform distribution, and the inner side surface of three pawls all is partial sphere shape concave arc surfaces suitable with probe; Positioning seat is vertical piece shape, vertically the piece bottom surface is fixedly connected with the locking frame, the locking frame is " C " font body, end is provided with square fixedly briquetting on the word of " C " font body, the word lower end of " C " font body is provided with tapped hole, be arranged with screw rod on the tapped hole, screw tip is fixedly connected with a spherical Connection Card ball, the outer movable sheath of Connection Card ball links and is connected to a movable holddown, be provided with in the movable holddown and the suitable inner chamber of Connection Card ball, the inner chamber opening diameter is slightly less than the Connection Card bulb diameter, and the screw rod lower end is connected with rotatable handle.
The beneficial effects of the utility model are: owing to be fixedly connected with the locking frame at the bottom of the positioning seat, the locking frame can make things convenient for and stably is fixed on the machinery equipment, and portable Three-Coordinate Measuring Arm can make things convenient for stable demarcation initial point when industry spot is used.
