Abstract

The utility model provides a cable meter counter, comprising a pressing wheel, a meter counting wheel, a pulse signal generator which measures the angular displacement of the meter counting wheel, and an intelligent counter which is connected with the pulse signal generator; the cable meter counter is characterized in that the pulse signal generator is an incremental angular displacement encoder which is coaxially and fixedly connected with the meter counting wheel and can change the angular displacement into periodic electric signal, change the electric signal into a counting pulse and present the displacement by the number of the pulses. The cable meter counter has the beneficial effect that as the encoder is used, the perimeter of the meter counting wheel can be equally divided, thus leading the cable length measuring precision not to be restricted by the perimeter of the meter counting wheel and improving the measurement precision.

Description

The cable meter-measuring device

Technical field

The utility model belongs to cable processing application technology field, relates in particular to a kind of cable meter-measuring device that cable finished product length is measured.

Background technology

For the metering of cable finished product length, relate to the use of cable products and commodity transaction both sides' the behavior of honouring an agreement quality, metering is inaccurate not only may to bring user's the inconvenience or the waste of commodity, and may cause commodity transaction both sides' dispute.Existing length of cable meter-measuring device, usually a share of cable finished product that will be measured by a less contact roller of diameter is pressed on the rice counting wheel circumference that diameter is big and girth is demarcated, drive the rotation of rice counting wheel by the one-way movement of cable, the rotation of rice counting wheel week is several then reads by optoelectronic switch, and demonstrates the length of the cable that is measured on the metering display by the conversion of signal.

In order to make accurate measurement, some improved technical schemes are suggested and are documented in the related publication.As Chinese patent application No. 200710044214.9 a kind of adjustable cable length meter-measuring device is disclosed, comprise handle, lifting threaded screw rod and standard wheels, the lifting threaded screw rod lower end symmetrical pinch roller identical with two connects, standard wheels is positioned at two identical symmetrical pinch roller belows, and cable can pass through between two identical symmetrical pinch rollers and standard wheels.Because the user can suitably be pressed on the circumferential surface of standard wheels cable by regulating handle, threaded screw rod, do not make the metering misalignment so can not slide relative take place substantially between cable and the standard wheels.Though this technical scheme has been dwindled the error range of length of cable metering to a certain extent, still exist because rice counting wheel (being above-mentioned standard wheels) girth is determined and this girth normally one make meter-measuring device can't accurately reflect the technical problem of cable finished product physical length than the integer value of length unit.

Summary of the invention

In order to overcome the above-mentioned technical problem of existing cable meter-measuring device, the utility model provides a kind of cable meter-measuring device that contains encoder, uses this meter-measuring device, can more accurately measure the physical length of cable finished product.

For achieving the above object, the technical solution of the utility model is: a kind of cable meter-measuring device, comprise contact roller, rice counting wheel, the pulse signal generator that angular displacement is measured to rice counting wheel and the intelligent counter that connects with pulse signal generator, it is characterized in that: described pulse signal generator is and the coaxial encoder that is fixedly connected of rice counting wheel.

As preferably, described encoder is the increment type displacement coder, its angular displacement can be converted to the periodic signal of telecommunication, again the signal of telecommunication is transformed into count pulse, and represents the size of displacement with the number of pulse.

Preferred as further starving, above-mentioned encoder whenever revolves three-sixth turn and generates 10 or 100 or 200 or the like a plurality of counting pulse signals.

The beneficial effects of the utility model are because used encoder, the rice counting wheel girth can be carried out many parts of five equilibriums, thereby make the length of cable measuring accuracy can break away from the restriction of rice counting wheel girth, the raising measuring accuracy.

Description of drawings

Further specify the utility model below in conjunction with drawings and Examples.

Fig. 1 is the planar structure schematic diagram of the utility model under in working order.

In the accompanying drawings, parts and numbering corresponding relation thereof are as follows: the 1-contact roller; The 2-cable; The 3-adjusting nut; The 4-support; The 5-rice counting wheel; The 6-encoder; The 7-intelligent counter.

Embodiment

What Fig. 1 showed is the planar structure schematic diagram of a kind of execution mode of the present utility model when finished cable is carried out gage work.

In this embodiment, use is that the setting girth is 1 meter a rice counting wheel 5.On the circumference cambered surface of this rice counting wheel 5, along whole circumference, be shaped on the shallow slot of a middle slight concave equably, the bottom land that the tangential direction that cable 2 is located with rice counting wheel 5 summits from left to right contacts this shallow slot passes through.

Above the cable of locating near rice counting wheel 5 summits 2, it is pair of pinch rollers 1, the height of contact roller 1 can be regulated by adjusting nuts 3 according to the different of condition such as the thickness of metering cable and rigidity, so that cable 2 moderately is pressed on the circumference cambered surface of rice counting wheel 5.Like this, continuous when mobile to the right when cable 2 from the left side, just can have slide relative ground and drive rice counting wheel 5 and clockwise rotate.

Rice counting wheel 5 and an increment type displacement coder 6 are fastened to each other, and rice counting wheel 5 can be around same pivot rotation with encoder 6.This pivot is fixedly mounted on the support 4, and is vertical with support 4.According to type selecting, when this encoder 6 revolved three-sixth turn simultaneously with rice counting wheel 5, when just 1 meter cable 2 was from left to right by rice counting wheel 5 vertex positions, these encoder 6 front and back generated 100 counting electric pulses altogether equably.These counting electric pulses are sent in the intelligent counter 7 that is installed in equally on the support 4 by lead.

This intelligent counter 7 can adjustment.In the present embodiment, in fact, reason owing to machining accuracy, the perimeter of rice counting wheel 5 is 99 centimetres, therefore, and before this cable meter-measuring device of operation, the conversion of each counting electric pulse that operating personnel have sent 7 pairs of encoders 6 of intelligent counter is set at 0.99 centimetre, like this, when rice counting wheel 5 is driven by cable 2 and rotates when week, the cable length that shows on intelligent counter 7 should be 99 centimetres.

As seen, utilize this cable meter-measuring device, not only can use 1/100 length of rice counting wheel 5 girths for unit metering cable finished product, than background technology is the extensive metering of unit with rice counting wheel 5 girths, can improve the accuracy of cable length metering greatly, and, because the precision of intelligent counter 7 can make the measuring accuracy of this cable meter-measuring device obtain further assurance according to the actual conditions adjustment.

Practice shows, uses the cable meter-measuring device of describing in the present embodiment, and error of meter counter is controlled within 0.5%.

Above embodiment has just described a kind of execution mode of the present utility model.Obviously, if evenly generate the encoder 6 of 200 counting electric pulses before and after selecting in this embodiment to use when revolving three-sixth turn altogether, then the measuring accuracy of this cable meter-measuring device is thirsted for further doubling.
