In foretell timber processing equipment's positioner, the below of at least one station has linked firmly the link on the work platform, link firmly two on the link along the vertical material cylinder that holds in the palm that sets up, work platform is last to have two vertical die-pins along longitudinal sliding connection, and the rear end of vertical die-pin can stretch out work platform's trailing edge, two vertical die-pin links firmly mutually with the piston rod of two material cylinders of holding in the palm respectively. The middle part of timber supports on work platform, and the tip of timber needs to be processed, but the length of timber is too big the time timber tip can appear decurrent deformation crooked, sets up the die-pin for this reason, and the die-pin cylinder drives the die-pin and stretches out, can stretch out the work platform part to timber and support, avoids the timber tip to warp crooked to improve processingquality.

In foretell timber processing equipment's positioner, two bar breachs have been seted up on the work platform, the connecting plate has been linked firmly on the vertical die-pin downside, and the lower extreme of connecting plate passes the bar breach and links firmly mutually with the piston rod that holds in the palm the material cylinder, the edge has vertically linked firmly the support material slide rail on the side of link, linked firmly the support material slider on the side of connecting plate, hold in the palm the material slider and hold in the palm material slide rail sliding fit. The material supporting slide rail can support the supporting rod, so that the supporting rod is kept stable under the pressure of wood, and the material supporting cylinder is protected.

Compared with the prior art, this timber processing equipment's positioner has following advantage:

1. because the position of adjusting the roof beam is adjusted through longitudinal drive spare for work platform supports the middle part position at timber when timber tip and the spacing plane of locating part offset, makes the focus of timber remain stable, and then can be more stable after fixing a position timber and process timber, improves processingquality.

2. The timber position is accurate because the timber tip leans against with spacing plane, and need not to measure the position of timber through the scale, and efficiency is higher.

3. Because the length of timber can appear decurrent deformation bending when too big, and this positioner sets up the die-pin, and the material cylinder that holds in the palm drives the die-pin and stretches out, can stretch out the work platform part to timber and support, avoids the timber tip to warp crooked to improve processingquality.
