Abstract
The invention relates to a three-dimensional curved surface measurement device. The device can be matched with a pressure measurement flat plate to directly measure the three-dimensional shape of the foot sole without the intermediate procedures of leaving a foot print on a piece of crushable block foam, casting a plaster model, acquiring by using a mechanical hand and the like. The measured information is digital and can be directly stored in a computer and transmitted through a network.
Description
Affiliated technical field
The present invention relates to a kind of device of measuring three-dimension curved surface, especially at the measurement of curved surface device of vola 3 dimensional coil geometry.
Background technology
At present, the method of known measurement vola 3 dimensional coil geometry is to tramp with one's feet on the rectangular parallelepiped bulk can be crushed foam, leave footprints, the gypsum of in this footprint, casting again, form the plaster cast of pin, use three-dimensional power hand (microscribe) to gather the three-dimensional coordinate of a plurality of points of this model sole again, to obtain curve form.The shortcoming of this method is: 1) expense height, can crush every of foam of rectangular parallelepiped bulk can only can not reuse 2 with once) speed is slow, the plaster cast sclerosis needs about 20 hours, and the technician needs about 20 minutes clock times with the three-dimensional coordinate of about 300 points of power hand getting collection.
Summary of the invention
The high and slow-footed shortcoming of expense for the existing vola of customer service method for measuring three-dimensional shape, the invention provides a kind of apparatus for measuring three-dimensional curved surface, this device can directly be measured the vola 3D shape, and need not to leave footprints through the bulk foam of can crushing, the casting plaster cast is with intermediate links such as power hand getting collection.Measured information is digitized, can directly transmit with the computer storage and by network.
The technical solution adopted for the present invention to solve the technical problems is: build combination rod (sticking plaster+spring+sticking plaster) array, approximately 30X10 centimetre
2, whenever with excellent area occupied 0.5x0.5 centimetre of combination
2. every combination rod is encapsulated in slightly larger in diameter in the round straight tube of combination rod, the self-movement up and down of combination rod.Pipe is encapsulated between two parallel plastic plates, and roundlet cap on the two end cap up and down of combination rod is placed any combination rod so up and down and can not skidded off in pipe.Such array is put on the pressure measurement flat board, and through calibration position, each rod bottom small cap is positioned at one above the pressure transducer just.Making up the distance of stretching out top plastic plate in excellent top is 5 centimetres, and the flexible required distance of middle springs is greater than 5 centimetres.Elasticity coefficient is by the precision and the susceptibility decision of used pressure measurement flat board.Precision and susceptibility such as the pressure measurement flat board are 1 kPa, and then the elastic coefficient can be calculated according to step once.We intend reaching a millimeter class precision, then can allow the corresponding 1 kPa of pressure of 1 millimeter length of spring compressed, and area is S=0.25cm
2, pressure is Sx pressure=0.025N. when measuring the sole shape, establishes 300 combination rods, on average compresses 2 centimetres, then overall required pressure is 0.025x20x300=150N.According to measured pressure distribution below the excellent array of combination, can inverse go out each and make up excellent compressed distance, thereby draw the shape of three-dimensional geometry curved surface like this.
The invention has the beneficial effects as follows, can measure vola three-dimension curved surface shape fast, measuring equipment utilizes existing device (plantar pressure is measured dull and stereotyped), makes the new effect of its performance.Single unit system is simple in structure.
Description of drawings
The present invention is further described below in conjunction with drawings and Examples.
Fig. 1 is a schematic diagram of the present invention.
Fig. 2 is the synoptic diagram with this measurement device three-dimension curved surface shape.
1. pressure measurement flat boards among the figure, 2. spring is 3. justified straight tube, 4. parallel-plate, 5. bottom small cap, 6. sticking plaster, 7. top small cap.
Embodiment
In Fig. 1, sticking plaster (a 6) part is enclosed in the round straight tube (3) by parallel-plate (4) with spring (2).Top small cap (7) and bottom small cap (5) link to each other with sticking plaster two ends (6) up and down respectively.During measurement wherein each bottom small cap require to be positioned at just on 1 pressure transducer of pressure measurement flat board (1).
In embodiment illustrated in fig. 2, top small cap (7) is pressed, middle springs (2) distortion, and pressure is by sticking plaster and the tested locating back of bottom small cap (5) (1) record.According to the force value of the elastic coefficient and the dull and stereotyped record of pressure measurement, can calculate the shape of three-dimension curved surface to be measured.
