Technical field
The utility model relates to a kind of mechanical measurer indicating gauge, specifically is meant a kind of mechanical type measurer indicating gauge with the data output function.
Background technology
Machinery measurer indicating gauge is meant mechanical dial gauge, mechanical clock gauge and adopts the general measurer with circular dial plate and rotation pointer such as inside meter with quadrat method indication result, feeler.Machinery measurer indicating gauge is a kind of standardized product, obtain for a long time and application widely because of it is cheap, stable and reliable for performance, but it can only pass through artificial reading, does not have digital display measurement data can not be exported, and can't incorporate the automation control area under the modern science and technology high speed development situation.
And have products such as the digital display centimeter of electronic signal output function or clock gauge, and essence is to adopt the linear displacement transducer that holds gate technique as survey instrument, the core component of this sensor is fixed grid and moving grid.Though this meter degree of accuracy height, easy to use, water proofing property is relatively poor, even if slight making moist also may cause the damage of table tool.
Price and performance advantage in view of mechanical measurer indicating gauge, if energy service-strong method realizes using mechanical measurer indicating gauge to detect simultaneously data is exported automatically, provide a kind of extremely reliable, stable, adapt to the rugged environment new product of work down, be industry institute pursuing target always.
The utility model content
The problem that the utility model need solve promptly is to adapt to industry requirement, and a kind of good waterproof performance, dependable performance, applied range, novel mechanical measurer indicating gauge easy to use and lower-cost are provided.
At the problems referred to above, the technical scheme that the utility model is taked is:
A kind of mechanical measurer indicating gauge with code-wheel is provided, and this table comprises dial plate, pointer, and a coding disc that rotates with pointer is installed in the described table, and signalization treatment circuit, data output interface; Circumferencial direction evenly is provided with hole or groove breach in coding disc upper edge, correspondence is provided with two detecting elements in the table, detecting element is used for detecting coding disc rotational angle, and the signal that detects is exported to signal processing circuit handle calculating, export to demonstration or high-end data acquisition equipment by data output interface at last, finally obtain measurement result.
Described detecting element can be optoelectronic switch or magnetic head; Described data output interface can adopt cable data transmission interface or wireless data transmission interface; Described coding disc can be positioned on the dial plate or also and can be loaded under the dial plate.
A kind of preferred scheme is: described coding disc is coaxial with pointer, relative fixed is also rotated synchronously.
Another kind of preferred scheme is: adopt between described coding disc and the pointer gear in proportion the mode of transmission be connected.
So mechanical measurer is when measuring, people not only can obtain measurement result intuitively by total indicator reading, can also this measurement data be detected by the matching mechanism of coding disc and detecting element and handle back output, realize the concentrated collection and the analysis of data, be convenient to robotization control.
The utility model adopts the mechanical type measurement structure substantially, and inside does not have the easy damp parts of rapid wear, and cost is low and have the stability, particularly humidity resistance of standard machinery measurer, has vast market prospect.
Description of drawings
Fig. 1 forms synoptic diagram for the utility model; Fig. 2 is the utility model one embodiment schematic appearance; Detecting element output waveform synoptic diagram when Fig. 3 is just changeing for code-wheel; Detecting element output waveform synoptic diagram when Fig. 4 reverses for code-wheel.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
As shown in Figure 1, 2, the utility model comprises dial plate 10, pointer 20, the one coding disc 1 with the pointer rotation is installed in the described table, described coding disc upper edge circumferencial direction is evenly distributed with hole or groove breach, correspondence is provided with two detecting element A and B that are used to detect coding disc rotational angle in the table, and the detecting element signal output part is connected successively with signal processing circuit 2, data output interface 3.
As shown in Figure 2, adopt coding disc and coaxial, the relatively-stationary mode of pointer among the embodiment, the coding disc is positioned at the dial plate top, and two detecting elements are arranged on coding disc edge.
Principle of work of the present utility model is: during measurement, pointer rotates the indication measurement situation, when pointer rotates, and coding disc and the coaxial synchronous rotation of pointer.Coding groove of disc or hole be over against detecting element the time, output high level, otherwise detecting element output low level.The coding disc constantly rotates, and just has the groove of respective numbers or aperture to cross detecting element, so detecting element just can be exported corresponding pulse number.
The angle intervals in groove or hole is even on the coding disc, and quantity is set to design half of quantification ability, and during actual fabrication, the coding disc is equally divided into some equal portions by angle, and every part of angle is θ, has half to be slotted or hole in every part.For example: for a circle is divided into 50 parts, obtain the system resolution of 1/50 circle, then need 25 grooves or hole.Its angle intervals computing method are: θ=360 ° ÷ 25=14.4 °.Two detecting elements are installed, can be calculated, for Integer N, as long as the angle installation interval about the list index axle of two groups of detecting elements
When the disc of then encoding rotated continuously, two detecting elements just can form A, B two-phase increment signal respectively, and output waveform makes up as Fig. 3,4.This waveform can not only reflect the absolute angle that the coding disc turns over by umber of pulse, and can reflect coding disc rotation direction by its phase information.When disc was rotated in the forward, as Fig. 3, B phase (lower waveform) output was than A phase (upper waveform) slow 1/4 cycle of output; And when the disc reverse rotation, as Fig. 4, then be that A phase (upper waveform) output is than B phase (lower waveform) slow 1/4 cycle of output.
A, B two-phase increment signal are exported from the cable data interface through " signal processing circuit " shaping, amplification back.
The utility model data output interface also can adopt the interface circuit with wireless data sending function, as infrared transtation mission circuit, radio frequency transtation mission circuit etc., gathers the display device communication with the terminal with corresponding receiving function.
The utility model also can between coding disc and pointer, adopt gear in proportion the mode of transmission be connected, its principle of work is the same, only needs collection display device by signal processing circuit or terminal be converted into measurement result and gets final product.
The above only is the utility model preferred implementation, should be pointed out that for a person skilled in the art, and under the prerequisite that does not break away from the utility model creation design, some changes and the improvement made all belong to protection domain of the present utility model.
