Description

The curve of arch automatic measuring instrument

Technical field

The utility model relates to the sports field, particularly a kind of skate blade radian curve device of measurement automatically that is used for.

Background technology

Curve of arch measurement both at home and abroad at present has following two kinds of methods: (1) location type curve of arch measuring instrument, as A type curve of arch measuring instrument, gauge outfit with 7 dial gauges during this apparatus measures is placed on the skates blade, carry out smoothing processing by methods such as curve fittings then, it can only measure 7 or limited point of skates blade, this surveying instrument can not reflect the true curved surface of skates blade, and bigger error is arranged.(2) sliding-type skates measuring instrument, as BHJ-1 type curve of arch detector, this apparatus measures is to be X-axis with the skates parallel direction, place a scale, be Y-axis with the direction of vertical skates blade, and place a dial gauge, promote dial gauge along X-direction during measurement, read the numerical value of dial gauge, and write down the numerical value of X-axis scale simultaneously, as X, the Y coordinate of a measurement point.Be drawn on the coordinate paper in the data with every bit, retouch out a curve with pen, this curve is the curve of arch curve.This curve uses more coarse, and it is equivalent to the curve that couples together with every little broken line.Can not obtain smooth measurement curve, but this method can obtain many relatively measurement points, is enhanced on measuring accuracy.

It is less to relate to the document of specializing in curve of arch measurement aspect as can be seen from the document that can retrieve.Wherein, the also special portable formula numerical control skates muller of cutter grinding that is fit to magnificent and Wang Xiaojiang research in the national numerical control system engineering technology of Central China University of Science and Technology research centre; In addition, spring of the Heilungkiang Research Institute of Physical Culture, the bosom was numerical control skates mullers with the consistent portable of development such as Liu Baogui, and computer function control system, curve of arch, roughness detection system, XYZ three-dimensional motion control system, grinding system, power dynamic, control circuit system are housed on it.The utility model volume is little, be convenient for carrying, can be by preset parameter and the ski-running of profiling automatic grinding, short-track speeding skating skates.

Summary of the invention

In order to solve the problems of the technologies described above, the utility model provides a kind of curve of arch automatic measuring instrument, and reading is directly perceived, measuring accuracy is high, be convenient to realize dynamic sampling, kinetic measurement.

The technical scheme that its technical matters that solves the utility model adopts is: a kind of curve of arch automatic measuring instrument, comprise base, skates fixed mount and support are installed on the base, the skates blade faces up and is installed on the skates fixed mount, level is installed scale on the support, install and measure the X-axis sensor of horizontal shift on the scale, the X-axis sensor connects together by the Y-axis sensor of crossbeam and measurement vertical displacement, and ball-screw is installed in the middle of the crossbeam; Motor also is installed on the base, on the output shaft of motor lower sprocket is installed, install sprocket wheel on the screw rod of ball-screw, lower sprocket is connected by chain with upper sprocket wheel.

As a kind of optimal way of the present utility model, limit switch is installed at described X-axis sensor two ends.

As a kind of optimal way of the present utility model, the signal controller of installation and compunication on the described base, its signal input part is connected with the Y-axis sensor with the X-axis sensor.

The beneficial effects of the utility model are: measure the transverse axis of skates blade curved surface and the coordinate of Z-axis respectively by adopting two grating displacement sensors, and can be with the form outputting measurement value of digital quantity, pass in the PC by the digital signal of data collecting card grating displacement sensor, calculating is also drawn out the best curve of arch curve of this motion under this project, but synkinesia person's training and match.

Description of drawings

Below in conjunction with the drawings and specific embodiments the utility model is done further concrete detailed explanation.

Fig. 1 is the structural drawing of curve of arch automatic measuring instrument;

Fig. 2 is the scheme of installation of two sensors on the curve of arch automatic measuring instrument.

Embodiment
