Embodiment

Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.

See accompanying drawing 1 to 5, the present embodiment comprises a kind of coupling positioning device, it comprises: two half-couplings be plugged in together 1, with the star cushion pad 2 be nested between two half-couplings 1 that elastic material is made, two described half-couplings 1 are respectively arranged with the first porose disc 3 and the second porose disc 4, described first porose disc 3 is provided with more than one first smooth verify 31, two adjacent described first smooth verifies 31 form the first stop every 32, described second porose disc 4 is provided with more than one second smooth verify 41, two adjacent described second smooth verifies 41 form the second stop every 42, described first smooth verify 31 and first stops every 32 regions be combined to form and described second smooth verify 41 with to have the second stop corresponding and form Guang Jian district every 42 regions be combined to form, described Guang Jian district is provided with optoelectronic switch 5, two described half-couplings 1 when not starting and normal transmission time, described first smooth verify 31 and second stops corresponding every 42, and described second smooth verify 41 and first stops corresponding every 32.Optoelectronic switch 5 is more than one, and more than one described optoelectronic switch 5 corresponding first stops the diverse location every 32.More than one described first smooth verify 31 and the rounded distribution of the second smooth verify 41.The half-coupling 1 be plugged in together described in two is star coupling.The half-coupling 1 be plugged in together described in described two is plum coupling.Described optoelectronic switch 5 is correlation optoelectronic switches.

Working procedure: as Fig. 2, shown in 4, when transmission shaft runs well, first smooth verify 31 and second stops every 42 correspondences, second smooth verify 41 and first stops every 32 correspondences, the light emission of such optoelectronic switch 5 is out stopped every 42 obstructs by the first stop every 32 and second, the receiving terminal of photoswitc 5 can't accept light, a steady state will be formed like this, when the load of load end increases to a certain degree, or mechanical transmission arrives the limit position of specifying, the half-coupling 1 of output terminal can be stopped, now two half-couplings 1 extrude mutually, star cushion pad 2 can be extruded distortion, now there is relative displacement in the first smooth verify 31 and the second smooth verify 41, as Fig. 3, shown in 5, such first smooth verify 31 and the second smooth verify 41 overlap, optoelectronic switch 5 is triggered, control system will receive the action of output shaft load variations, just can stop the power supply of output motor immediately.Thus reach the effect of coupling location.After power motor reversion, the first porose disc 3 and the second porose disc 4 recover in original state, and the passage of light of optoelectronic switch 5 is stopped, device gets back to normal working.

Two half-couplings 1 are all shaped with convex tooth, the star shock absorber 2 made with class materials such as rubber, between the convex tooth being placed on two half-couplings 1.During work, star elastic component pressurized contracts transmitting torque.This coupling allows the radial displacement of axle to be 0.2mm, and drift angle displacement is 1 ° of 30', and because of an elastic component pressurized not tension, working condition makes moderate progress, therefore the life-span is longer.

Plum coupling structural type and working principle similar to star-shaped elastic coupling, but the hole that half-coupling coordinates with axle can be made cylindrical or conical, and replaces star elastic component with quincunx elastic component.Elastic component can select the material manufacture such as urethane rubber, monomer cast nylon of different hardness according to requirements.Operating temperature range is-35 ~+80 ° of C, and short-term operation temperature can reach 100 ° of C, and the nominal torque of transmission is 16 ~ 25000Nm.

Working principle: two half-couplings be plugged in together 1, two half-coupling geo-stationary when running well, the shape cushion pad 2 of setting when the transmission shaft mechanical transmission of driven end is obstructed is extruded generation deformation, now there is relative displacement in two half-couplings 1, be arranged on the first porose disc 3 on two half-couplings 1 and the second porose disc 4 relative displacement occurs thereupon, original like this first not corresponding smooth verify 31 and the second smooth verify 41 can be overlapping, the end machinery action that the light of such optoelectronic switch 5 can obtain driven shaft transmission part by the first smooth verify 31 and the second smooth verify 41 signal transmission to controller puts in place.
