Summary of the invention
Technical problem to be solved in the utility model provides a kind of lay pitch test machine, is provided with the counter of two record backtwisting revolutions, and record accurately, and is easy to use.
The utility model adopts following technical scheme.
Lay pitch test machine, include cabinet, the sample holder device, gearing and control panel, it is characterized in that: but the record that is installed on the cabinet also included, the counter and the photoelectricity revolution inductor that show the rotation axis revolution, gearing comprises reducing motor and rotation axis, one end of rotation axis links to each other with the reducing motor output terminal, the other end links to each other with rotation chuck in the sample holder device, the revolution wheel is housed on the rotation axis, revolution wheel is connected by driving-belt with counter wheel on the counter, photoelectricity revolution inductor is positioned at by the rotation axis side, is equipped with on the rotation axis and the corresponding inductive rod of rotating synchronously with rotation axis of photoelectricity revolution sensor location.
Described revolution wheel is all sprocket wheel of the same size with counter wheel, and driving-belt is a chain.
Described sample holder device comprises rotation chuck, fixed chuck, tension force counterweight and load weight, a termination of the tight sample of rotating clip head-clamp, and the other end behind the heavy burden tension force counterweight of fixed chuck clamping sample, the shaft tail end of fixed chuck links to each other with load weight.
The indicator gauge that can show the rotation axis revolution that links to each other with photoelectricity revolution inductor is installed on the described control panel.
Advantage of the present utility model is: the utility model is provided with two counters, and one is mechanical counter, makes zero after writing down just commentaries on classics, counter-rotating revolution or the forward and backward that shows rotation axis.One is the photo-electric sense counter, and rotation axis rotates, and by photoelectricity revolution inductor, shows on indicator gauge, can write down the revolution that adds up of rotation axis.Record is accurate, convenient reading, and easy to use, the lay pitch of calculating is accurate.Lay pitch computing formula is L=d/n, and the two ends of steel cord are rotated chuck and fixed chuck clamping respectively, and d is the length of steel cord between two chucks, and n is certain one revolution of rotation axis during by backtwisting fully of steel cord.The utility model is provided with two counterweights, one is the tension force counterweight, 20 newton, one is load weight, 20 newton, they use and effect has nothing in common with each other, after an end of steel cord is rotated chuck and clamps, the hole that the other end passes fixed chuck link to each other with the tension force counterweight be subjected to behind the heavy burden tension force clamped again.After fixed chuck clamped the steel cord, its shaft tail end linked to each other with load weight again, and in the backtwisting process, the steel cord is subjected to the tensile force of load weight.Such structure makes test more accurate.

Fig. 2 is the vertical view of Fig. 1.
Embodiment
With accompanying drawing the utility model is further described in conjunction with the embodiments.
Lay pitch test machine, include cabinet, the sample holder device, gearing and control panel, but also include the record that is installed on the cabinet, the counter 24 and the photoelectricity revolution inductor 27 that show rotation axis 22 revolutions, gearing comprises reducing motor 21 and rotation axis 22, one end of rotation axis links to each other with shaft joint with the reducing motor output terminal, the other end links to each other with rotation chuck 6 usefulness shaft joints in the sample holder device, revolution wheel 23 is housed on the rotation axis, revolution wheel is connected by driving-belt 26 with counter wheel 25 on the counter 24, photoelectricity revolution inductor 27 is positioned at rotation axis 22 sides and is close to, and is equipped with on the rotation axis 22 and the corresponding inductive rod 28 of rotating synchronously with rotation axis of photoelectricity revolution sensor location.Reducing motor is installed on the preceding bearing 32 that is fixed on the cabinet.
Described revolution wheel 23 is all sprocket wheel of the same size with counter wheel 25, and driving-belt 26 is a chain.
Described sample holder device comprises rotation chuck 6, fixed chuck 2, tension force counterweight 4 and load weight 3, rotate chuck and fixed chuck and be positioned at same horizontal line, one termination of the tight sample 1 of rotating clip head-clamp, the other end behind the heavy burden tension force counterweight of fixed chuck clamping sample 1, the shaft tail end of fixed chuck links to each other with load weight.The axle of fixed chuck is supported and can be done axial displacement in its hole but can not rotate by being contained in rear support 31 on the cabinet.
The indicator gauge 29 that can show rotation axis 22 revolutions that links to each other with photoelectricity revolution inductor is installed on the described control panel.
The method of operating of this machine of summary:
Utilize the sample holder device to clamp the steel cord, operate as follows: after an end of steel cord is rotated the chuck clamping, the hole that the other end passes fixed chuck link to each other with the tension force counterweight be subjected to behind the heavy burden tension force clamped again.After fixed chuck clamped the steel cord, its shaft tail end linked to each other with load weight again, and in the backtwisting process, the steel cord is subjected to the tensile force of load weight.When backtwisting, starter motor, rotation axis drive the rotation chuck and rotate synchronously, and the rotating clip head drives steel cord backtwisting, and fixed chuck does not rotate.The length of steel cord is d between two chucks, d=500 ± 1mm.Rotation axis rotates, and counter and indicator gauge demonstrate the revolution of rotation axis.Revolution n when writing down outermost one complete backtwisting, its lay pitch L=d/n.Untie outermost one back and it is separated, cuts off, make it not twine second strand with instrument.The revolution value on the counter is made zero in the motor counter-rotating, and backtwisting is second strand again, but the sense of rotation of rotation axis is read revolution n behind the backtwisting fully with last opposite
2, calculate lay pitch L
2=d/n
2And the like, remaining strand of backtwisting and the calculating lay pitch.
