Abstract
Disclosed is a measurer for three-dimension surface shape of last, comprising a projection and imaging optical system, a locomotion and rotation workbench, a linear array detector, an intelligent controller, etc. The utility model belongs to a non-contact photoelectric measurement apparatus using triangulation theory and light pencil relative scan mode, which is combined in use with each type of microcomputers by RS-232 general interface and can automatically measure new designed last samples or lasts in mass production and get all the desired sizes of feature parts and high precision surface shape data. The utility model can be widely used in computer-aided design system (CAD) and computer-aided manufacture system (CAM) in shoemaking industry and also for measuring high precision surface shape of industrial component parts of the same industry and physical models. The utility model has the advantages of shoe-form design accelerating and the competitive power of shoemaking and products increasing.
Description
The utility model belongs to the 3 d shape measuring instrument, especially for the instrument of shoe tree 3 d shape measurement.
In shoemaking industry, no matter be newly-designed female sample, still the shoe tree of mass production all must be measured check to the size and the profile of its each characteristic portion of shoe last or hat block body, particularly computer aided design system that developed recently gets up in the shoemaking industry (CAD) and computer aided manufacture system (CAM) more need the 3 d shape data of whole shoe tree.Because shoe last or hat block shape more complicated, be difficult to its overall dimension of check and profile, the domestic conventional shoe last or hat block type instruments of inspection (for example drawing hand, linen measure tape, preceding measuring appliance and the coordinate caliper etc. of lifting up) that can only rely on for a long time is to measuring at main position, all the other positions and shape as for shoe tree, only can by virtue of experience differentiate with eyesight (referring to: " Chinese footwear sizes and shoe tree design " book chapter 6, shoe tree design and check, light industry publishing house).Though adopted three-coordinate measuring machine that shoe tree is measured abroad, this measuring machine is the high-accuracy general measurement device, cost an arm and a leg, and measuring speed to be slow, domestic so far Shoes Factory does not introduce as yet and uses.
Task of the present utility model is to propose a kind of 3 d shape measuring instrument that is used for the shoe tree automatic gauging.The online use of this measuring instrument and microcomputer, can measure the whole 3 d shape data of each shoe tree and required whole feature size automatically, these data can be widely used in shoemaking industry computer aided design system (CAD) and computer aided manufacture system (CAM).
Accompanying drawing 1 is a structural representation of the present utility model.
Accompanying drawing 2 is intelligent controller principle circuit diagrams.
The utility model is according to principle of triangulation, adopts light pencil relative scanning mode and non-contact optoelectronic measuring method to measure.As shown in Figure 1, the utility model is made up of light source (1), imaging lens (2), linear array detector (3), intelligent controller (4) and workbench (5).The a branch of light pencil of light source projects (being called throw light) forms a small luminous point (being called object point) on the shoe tree surface, linear array detector is positioned at the image plane of imaging lens, on linear array detector, the variation of object point radial position will make image point move on detector to object point through the imaging lens imaging.Luminous point on light source, the shoe tree, imaging lens and linear array detector are positioned at same plane, and make throw light and imaging light in an acute angle, constitute two limits of triangulation mode intermediate cam shape.Workbench drives shoe tree and moves vertically and rotate around axis, so that throw light can carry out relative scanning to whole shape of shoe tree.The circuit of workbench links to each other with intelligent controller, requires to realize moving and rotating of asynchronous input according to measuring.Linear array detector links to each other with intelligent controller, and intelligent controller is finished turntable driving, the preliminary treatment to the linear array detector output signal, analog-to-digital conversion and data and handled.The utility model needs and the online use of microcomputer, and by intelligent controller finish and microcomputer between the bi-directional of data and control signal, measurement result is exported by microcomputer.
Light source (1) can adopt small-power He-Ne laser instrument, also can increase pinhole filter and projection optical system to improve the quality of hot spot.
For increasing measuring reliability, can adopt two linear array detectors, and with it about the throw light balanced configuration.
The detailed structure of workbench (5) can be as the A among Fig. 1 to shown in the view.Base (6) both upper ends thereof respectively has a supporting (7), between two supportings rhizoid bar (8) and two polished rods (9) have been installed, the transmission nut that is connected with screw mandrel (10) is fixed on table top (11) bottom center, respectively there is a guide holder (12) that is enclosed within on the polished rod at two ends, table top below, the two ends of table top top have a tailstock (13) and a rotating disk (14) respectively, and shoe tree is installed between tailstock and the rotating disk.The stepper motor of screw mandrel outer end (15) drives screw mandrel and rotates, and moves vertically by transmission nut promotion table top and shoe tree, and the stepper motor of rotating disk outer end (16) drives shoe tree by rotating disk and rotates around axis.
Intelligent controller (4) can be made up of linear array drive circuit (I), stepper motor driving circuit (II), signal pre-processing circuit (III) and single board computer (IV), as shown in Figure 2.The two ends of linear array drive circuit are connected with single board computer (IV) with linear array detector (3) respectively, realize the automatic scan of linear array detector (3).The preamplifier (PA) of the output of linear array detector (3) in signal pre-processing circuit (III) through peak-holding circuit (PH) and analog-digital converter (A/D), sent into single board computer (IV) more then.The two ends of stepper motor driving circuit (II) respectively with single board computer (IV) and workbench (5) on two stepper motors (15,16) connect.Single board computer can comprise CPU (Z80-CPU), read-only memory (EPROM), memory (RAM), input/output interface (Z80-PIO) and serial communication interface (RS-232), by the communication of serial communication interface realization with microcomputer, the instruction of reception control of microcomputer, finish sampling, calculate and the control function, and send result of calculation back to microcomputer.
Measurement result of the present utility model (shoe tree 3 d shape data) or standby with the document form data deposit, or on CRT, export, or on plotter, export, Fig. 3 is the measurement result by plotter output.
The utility model is as a kind of intelligent terminal equipment, by the RS-232 general-purpose interface can with the online use of all kinds of microcomputers, can not only realize fast and high-precision automatic measurement all kinds of shoe trees, also can be used for the surface shape measurement of other similar industrial parts and mock-up.
