Abstract
The utility model discloses a kind of straight-line motion mechanism, this mechanism comprises telescopic body (4), pedestal (1), tooth bar, double cog synchronous belt (3), driving pulley (2), driven pulley (5), holder rail, (1) is provided with rectilinear orbit to pedestal, telescopic body (4) is slidably arranged on the track of pedestal (1), drags the tooth bar be arranged on telescopic body (4) make telescopic body (4) along the guide rail two-way linear motion on pedestal (1) by double cog synchronous belt (3).
Description
Technical field
The present invention relates to a kind of straight-line motion mechanism.
Background technique
Existing straight-line motion mechanism mainly contains gear rack motion, screw telescopic mechanism, cylinder, oil cylinder etc., the straight line motion distance of these mechanisms all can not exceed the length of the motions itself such as tooth bar, screw rod or cylinder body, in order to increase move distance, the multistage motion of general employing, but multistage motion motion is discontinuous, complex structure.
Summary of the invention
Technical problem to be solved by this invention is to provide the two-way linear motion that a kind of straight line motion is greater than this body length of mechanism.
Technological scheme of the present invention is: a kind of straight-line motion mechanism, comprise telescopic body, pedestal, tooth bar, double cog synchronous belt, driving pulley, driven pulley, holder rail, left limit block, right limit block, described pedestal is provided with rectilinear orbit, telescopic body is slidably arranged on the track of pedestal, driving pulley is arranged on the left end of pedestal, 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 to be fixedly mounted on telescopic body and to engage with double cog synchronous belt, holder rail is slidably arranged on telescopic 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.
Straight-line motion mechanism of the present invention is work like this: when telescopic 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 telescopic body makes telescopic body along the straight line motion left of the guide rail 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, be now the limit of telescopic body to left movement; When telescopic 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 telescopic body makes telescopic body along the straight line motion to the right of the guide rail 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, it is now the limit that telescopic body moves right.
Straight-line motion mechanism of the present invention drags by double cog synchronous belt the tooth bar be arranged on telescopic body makes telescopic body along the guide rail straight line motion on pedestal, telescopic body moves to the top of driving pulley to the right-hand member that the limit position of left movement is tooth bar, the limit position that telescopic body moves right is the top that the left end of tooth bar moves to driven pulley, the total move distance of telescopic body be two Idle wheels centre distance with and add the length of upper rack, there is the advantage that move distance is long; In addition, because holder rail is slidably arranged on telescopic 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 movement between double cog synchronous belt, when only having arrival left limit block or right limit block, just there is relative movement between holder rail and double cog synchronous belt, the wearing and tearing of double cog synchronous belt can be reduced like this, also double cog synchronous belt can be made to engage with tooth bar more reliable.
