Abstract
The utility model discloses a rack -gear drive expansion bend belongs to mechanical equipment technical field. This expansion bend, including drive arrangement, drive arrangement output on be connected with the gear, be provided with the rack with the gear cooperation, gear revolve drive rack carries out concertina movement, the rack on the driving cog set up down, be provided with guider in rack side. This device is small, high transmission efficiency, and the motion process is accurate, and simple structure is applicable to and uses the occasion that realizes the push -and -pull action in narrow and small space.
Description
Technical field
The utility model relates to a kind of expansion bend, and particularly a kind of rack geared expansion bend, belongs to mechanical equipment technical field.
Background technique
In current integration of equipments mechanization manufactures, many occasions need to use straight line motion shrinking structure, the machinery realizing straight line motion shrinking structure is provided with multiple, as cam, linear electric motor, cylinder, oil cylinder etc., some specific occasions, the space of installing fore and aft motion structure is very limited, and have certain requirement to the thrust of expansion bend or pulling force size, also require that the movement locus in telescopic process meets the requirements, although these structures all can realize straight line motion above, but ubiquity transformation efficiency is low, if this causes realizing the equipment that the pulling force of a certain particular value or thrust must select higher force performance, and the raising of mechanical property is mostly along with the increase of equipment volume, the needs of specific small space cannot be met, in device fabrication, need a kind of volume little, conversion efficiency is high, move accurate linear telescopic motion.
Summary of the invention
The purpose of this utility model is to overcome the above-mentioned technical problem existed in above-mentioned straight line motion extending means, provides a kind of rack geared expansion bend.
For realizing the purpose of this utility model, have employed following technological scheme: a kind of rack geared expansion bend, comprise drive unit, described drive unit is connected with gear on exporting, tooth bar is equipped with gear, pinion rotation drives tooth bar to carry out fore and aft motion, driving cog on described tooth bar is arranged down, tooth bar side is provided with guiding device, further, motor connects speed reducer, gear is connected in the output of speed reducer, further, the guiding device that described tooth bar side is arranged is: on tooth bar side length direction, arrange direction recess from front to back, described direction recess front end is flare openings, rack stroke track is provided with the multiple runners corresponding with direction recess, runner is arranged on the stationary axle of substantially horizontal, further, described guiding device is arranged in the bilateral symmetry of tooth bar.
Positive Advantageous Effects of the present utility model is: compared with prior art, this device volume is little, and transmission efficiency is high, and movement process is accurate, and structure is simple, is applicable to be applied in the occasion realizing push pull maneuver in small space.
Accompanying drawing explanation
Fig. 1 is schematic front view of the present utility model.
Fig. 2 is elevational schematic view of the present utility model.
Fig. 3 is the schematic diagram of guide mechanism.
Embodiment
In order to explain enforcement of the present utility model more fully, provide embodiment of the present utility model.These embodiments are only to elaboration of the present utility model, do not limit scope of the present utility model.
Elaboration detailed further to the utility model by reference to the accompanying drawings, is respectively labeled as in accompanying drawing: 1: motor; 2: speed reducer; 3: housing; 4: gear; 5: tooth bar; 51: direction recess; 52: flare openings.As shown in drawings, tooth bar 5 is arranged in housing 3, gear 4 is arranged in the output of speed reducer 2, the output terminal of motor connects speed reducer, speed reducer 2 is bolted on housing 3, the clockwise and anticlockwise of driven by motor speed reducer, realize the fore and aft motion of tooth bar 5, the bilateral symmetry of tooth bar is provided with direction recess, 51 direction recess being depicted as side, in the front end of direction recess, flare openings is set, as shown at 52, rack stroke track is provided with the multiple runners corresponding with direction recess, runner be arranged on the stationary axle of substantially horizontal, the diameter of runner and the width of direction recess adapt, multiple runners of both sides are not shown in figure.Compared with prior art, this device volume is little, and transmission efficiency is high, and utilize the groove on tooth bar to coordinate guidance capability to lose with runner few, movement process is accurate, and structure is simple, is applicable to be applied in small space the occasion requiring to realize the action of push-pull effort.
After detailed description mode of execution of the present utility model, the personage being familiar with this technology can be well understood to, do not departing under above-mentioned claim and spirit and can carry out various change and amendment, all above embodiment is done according to technical spirit of the present utility model any simple modification, equivalent variations and modification, all belong to the scope of technical solutions of the utility model, and the utility model is not also limited to the mode of execution of example in specification.
