Abstract
The invention discloses a kind of retractable forks of long stroke, the pallet fork includes fork body (4), pedestal (1), rack gear, double cog synchronous belt (3), driving pulley (2), driven pulley (5), support rail, pedestal is provided with rectilinear orbit on (1), fork body (4) can be slidably mounted on the track of pedestal (1), make to pitch the track two-way linear movement of body (4) on pedestal (1) by the rack gear that double cog synchronous belt (3) dragging is mounted on fork body (4).
Description
Technical field
The present invention relates to a kind of retractable forks.
Background technique
Existing retractable fork is mainly driven by rack-and-pinion, cylinder or oil cylinder, and the distance of stretch out and draw back of pallet fork is all no more than tooth
The length of the movement mechanisms such as item or cylinder body itself, stroke is shorter, general to use multistage movement mechanism in order to increase distance of stretch out and draw back,
But multistage movement mechanism movement is discontinuous, and structure is complicated.
Summary of the invention
Technical problem to be solved by the invention is to provide a kind of retractable forks of long stroke.
The technical scheme is that a kind of retractable fork of long stroke, including fork body, pedestal, rack gear, double cog are synchronous
Band, motor, driven pulley, holds in the palm rail, left limit block, right limit block at driving pulley, is provided with rectilinear orbit on the pedestal, pitches
Body can be slidably mounted on the track of pedestal, and driving pulley is mounted on the left end of pedestal, and motor is connected by shaft and driving pulley
It connects, driven pulley is mounted on the right end of pedestal, and double cog synchronous belt is driven and is tensioned by driven pulley, main belt by driving pulley
Double cog synchronous belt tensioning between wheel and driven pulley is in line and the parallel track with setting on the base, the fixed peace of rack gear
It being engaged on fork body and with double cog synchronous belt, support rail can be slidably mounted on fork body, and support rail can hold double cog synchronous belt,
It prevents double cog synchronous belt from deviating from from the tooth socket of rack gear, makes double cog synchronous belt and rack gear positive engagement, the installation of left limit block
In the left end of pedestal, for holding in the palm the left limit of rail, right limit block is mounted on the right end of pedestal, for holding in the palm the right limit of rail.
The double cog synchronous belt can be two-sided ladder-shaped toothed timing, be also possible to two-sided arc tooth synchronous belt.
The retractable fork of long stroke of the invention works in this way: when fork body needs to move downward, driving pulley driving
Double cog synchronous belt is run to the left, the rack gear that double cog synchronous belt dragging is mounted on fork body make to pitch track of the body on pedestal to
Left linear motion, under the action of holding in the palm rail, rack gear and double cog synchronous belt keep engaging until the right end of rack gear move to master
The top of movable belt pulley, referring to fig. 4, the limit moved downward at this time for fork body；When fork body needs to run to the right, driving pulley driving
Double cog synchronous belt is run to the right, the rack gear that double cog synchronous belt dragging is mounted on fork body make to pitch track of the body on pedestal to
Right linear motion, under the action of holding in the palm rail, the holding of rack gear and double cog synchronous belt engage until the left end of rack gear move to it is driven
The top of belt wheel is at this time the limit that moves right of fork body referring to Fig. 5.
The retractable fork of long stroke of the invention makes to pitch body by the rack gear that double cog synchronous belt dragging is mounted on fork body
Rail linearity on pedestal moves, and the extreme position that fork body moves downward is that the right end of rack gear moves to the upper of driving pulley
Side, the extreme position that fork body moves right are that the left end of rack gear moves to the top of driven pulley, and the total move distance of fork body is
The center of two belt wheels has the advantages that stroke is long away from the length for adding rack gear；In addition, since support rail can be slidably mounted at fork body
On, support rail follows between right limit block in left limit block to be moved together with double cog synchronous belt, is not had between double cog synchronous belt
There is relative motion, when only reaching left limit block or right limit block, holding in the palm between rail and double cog synchronous belt just has relative motion, this
Sample can be reduced the abrasion of double cog synchronous belt, and it is more reliable that double cog synchronous belt can be made to be engaged with rack.
