Abstract
The invention discloses a long-stroke retractable fork. The fork comprises a fork body (4), a base (1), a rack, a double cogged synchronous belt (3), a driving belt wheel (2), a driven belt wheel (5) and a supporting rail, wherein a linear rail is arranged on the base (1), the fork body (4) is installed on the rail of the base (1) in a sliding mode, and the rack installed on the fork body (4) is dragged through the double cogged synchronous belt (3) to enable the fork body (4) to perform the bidirection linear motion along the rail on the base (1).
Description
Technical field
The present invention relates to a kind of retractable fork.
Background technology
Existing retractable fork is primarily of rack-and-gear, cylinder or hydraulic oil cylinder driving, the distance of stretch out and draw back of pallet fork all can not exceed the length of the kinematic mechanism such as tooth bar or cylinder body itself, stroke is shorter, in order to increase distance of stretch out and draw back, the multistage kinematic mechanism of general employing, but multistage kinematic mechanism motion is discontinuous, complex structure.
Summary of the invention
Technical matters to be solved by this invention is to provide a kind of retractable fork of Long travel.
Technical scheme of the present invention is: a kind of retractable fork of Long travel, comprise fork body, pedestal, tooth bar, double cog synchronous belt, driving pulley, motor, driven pulley, holder rail, left limit block, right limit block, described pedestal is provided with rectilinear orbit, fork body is slidably arranged on the track of pedestal, driving pulley is arranged on the left end of pedestal, motor is connected with driving pulley by rotating shaft, driven pulley is arranged on the right-hand member of pedestal, double cog synchronous belt is driven by driving pulley and by driven pulley tensioning, double cog synchronous belt tensioning between driving pulley and driven pulley be in line and with the parallel track be arranged on pedestal, tooth bar is fixedly mounted on to be pitched on body and engages with double cog synchronous belt, holder rail is slidably arranged on fork body, holder rail can hold double cog synchronous belt, prevent double cog synchronous belt from deviating from from the teeth groove of tooth bar, make double cog synchronous belt and tooth bar positive engagement, left limit block is arranged on the left end of pedestal, for holding in the palm the left limit of rail, right limit block is arranged on the right-hand member of pedestal, for holding in the palm the right limit of rail.
Described double cog synchronous belt can be two-sided ladder-shaped toothed timing, also can be two-sided arc tooth synchronous belt.
The retractable fork of Long travel of the present invention is work like this: when fork body needs to left movement, driving pulley drives double cog synchronous belt to run left, double cog synchronous belt drags the tooth bar be arranged on fork body makes fork body along the straight-line motion left of the track on pedestal, under the effect of holder rail, tooth bar and double cog synchronous belt keep engaging until the right-hand member of tooth bar move to the top of driving pulley, see Fig. 4, now for fork body is to the limit of left movement; When fork body needs to run to the right, driving pulley drives double cog synchronous belt to run to the right, double cog synchronous belt drags the tooth bar be arranged on fork body makes fork body along the straight-line motion to the right of the track on pedestal, under the effect of holder rail, tooth bar and double cog synchronous belt keep engaging until the left end of tooth bar moves to the top of driven pulley, see Fig. 5, now for pitching the limit that body moves right.
The retractable fork of Long travel of the present invention drags by double cog synchronous belt the tooth bar be arranged on fork body makes fork body move along the rail linearity on pedestal, fork body moves to the top of driving pulley to the right-hand member that the end position of left movement is tooth bar, the end position that moves right of fork body is the top that the left end of tooth bar moves to driven pulley, the total move distance of fork body is the length that the width between centers of two belt wheels adds upper rack, has the advantage that stroke is long; In addition, because holder rail is slidably arranged on fork body, holder rail is followed double cog synchronous belt and is together moved between left limit block and right limit block, and there is no relative motion between double cog synchronous belt, when only having arrival left limit block or right limit block, just there is relative motion between holder rail and double cog synchronous belt, the wearing and tearing of double cog synchronous belt can be reduced like this, and it is more reliable that double cog synchronous belt can be made to engage with tooth bar.
