Abstract
The utility model discloses a constant-force tension device. A guiding rod (2) is provided with a lower metal proximity sensor (12) and an upper metal proximity sensor (13), an upper pulley supporting seat (3) is arranged at the upper end position of the guiding rod (2), the upper pulley supporting seat (3) is provided with an upper pulley block (4), the guiding rod is connected with a linear bearing supporting seat (6) and a stringing wheel (9), the lower end position of the guiding rod (2) is connected to a base of the constant-force tension device, a lower pulley block (7) is connected with the linear bearing supporting seat (6), and the stringing wheel (9) is connected with an electric motor reduction box (11) through a bearing. The constant-force tension device disclosed by the utility model has the main principle that by utilizing the vertical uniform motion of movable pulley blocks and the performance of a storage steel wire rope, constant tension stringing can be supplied for a steel wire rope, the labor force can be reduced, and the uniform tension force of the steel wire rope can be ensured.
Description
Technical field
The utility model relates to automobile backguy field, relates in particular to steel wire rope constant-tension unwrapping wire, so that the high accuracy fixed length is cut off.
Background technology
Automobile backguy field steel wire rope pay off rack adopts passive unwrapping wire at present, drags steel wire rope by stepper motor drive steel wheel or synchronous belt and moves, and stepper motor turns to specifies the fixed length step pitch to stop, and cuts off steel wire rope then.Because steel wire rope tension is inhomogeneous, steel wire rope possibly drag generation slip relatively in the process at steel wheel or synchronous belt, thereby directly influences the degree of accuracy of steel wire rope sheared length.
Summary of the invention
To the deficiency that above-mentioned technology exists, the utility model provides a kind of constant force tensioning apparatus, can prevent that steel wire rope tension is inhomogeneous.
For realizing above-mentioned purpose; The technical scheme that the utility model adopted is: a kind of constant force tensioning apparatus; Form by guide rod (2), top sheave supporting seat (3), top sheave group (4), linear bearing supporting seat (6), downslide wheels (7), actinobacillus wheel (9), cylinder (10), motor reduction gearbox (11), time metal proximity transducer (12), last metal proximity transducer (13); It is characterized by: metal proximity transducer (12) down is housed on guide rod (2); Last metal proximity transducer (13); Top sheave supporting seat (3) is equipped with at the position, upper end of guide rod (2), top sheave group (4) guide rod (2) is housed on the top sheave supporting seat (3) has connected linear bearing supporting seat (6) and actinobacillus wheel (9), and lower end part is connected to the base of device; Downslide wheels (7) are connected with linear bearing supporting seat (6), and actinobacillus wheel (9) is connected with motor reduction gearbox (11) through bearing.
Metal proximity transducer (12) is housed down on the described linear bearing supporting seat (6);
The described metal proximity transducer (13) of going up is contained on the guide rod (2) between top sheave supporting seat (3) and the linear bearing supporting seat (6).
The beneficial functional of the utility model is: cardinal principle is to utilize up and down uniform motion and store the performance of steel wire rope of running block; Steel wire rope constant-tension unwrapping wire can be provided; The assurance steel wire rope tension is even, and former cutting length size fluctuation scope can be reduced to native 1mm now at native 5mm.

Marginal data:
Frame (1), guide rod (2), top sheave supporting seat (3), top sheave group (4), steel wire rope (5), linear bearing supporting seat (6), downslide wheels (7), actinobacillus wheel support (8), actinobacillus wheel (9), cylinder (10), motor reduction gearbox (11), time metal proximity transducer (12), last metal proximity transducer (13).
The specific embodiment
Be described further below in conjunction with 1,2 pairs of the utility model of accompanying drawing:
The first step: with the steel wire rope reel frame (1) of packing into; Pull out cable wire end; Through directive wheel (14), top sheave group (4) Far Left pulley, downslide wheels (7) Far Left pulley; Successively respectively around to pulley, pull out the steel wire rope blanking machine of making a gift to someone from top sheave group (4) rightmost pulley then from left to right.
Second step: start the steel wire rope blanking machine, downslide wheels (7) will at the uniform velocity rise, when linear bearing supporting seat (6) contacts with last metal proximity transducer (13); Motor reduction gearbox (11) starts, and drives actinobacillus wheel (9) and rotates unwrapping wire, and downslide wheels (7) will at the uniform velocity descend; When linear bearing supporting seat (6) contacts with following metal proximity transducer (12), motor reduction gearbox (11) stops, and actinobacillus wheel (9) stops; Rotate, unwrapping wire stops.
Carry out so repeatedly, can guarantee that steel wire rope tension evenly is drawn into to cut out high accuracy fixed length steel wire rope in the steel wire rope blanking machine.
