Description
Technical field
The present invention relates to a kind of wood working tool, specifically refer to workpiece clamping structure.
Background technology
The mechanization gradually of China's timber processing industry starts from the late Qing Dynasty.At this moment the foreign trader sets up the mechanization sawmill in China, then develops the wood-working factories take building construction as object such as floor, door and window; The 20 beginnings of the century production glued board of setting up factories again.From the mid-50, plywood production has had development, follows and begins to make particieboard and fiberboard; Surface decoration material and laminated timber etc. also occur successively.This indicates the modernization period of wood-processing industry centered by having entered to fully utilize of China.In modern timber processing industry, particularly woodwork industry, surfacer is the electric power tool of commonly using.Usually, surfacer need to be installed the shuttle plate on the platform of surfacer when carrying out cutting operation, limited the width of timber by the shuttle plate, so that processing.But, if frequent if the width of wood workpiece changes, need often to change different shuttle plates, therefore, the supporting amount of its shuttle plate is large, and changes trouble.
Summary of the invention
The object of the present invention is to provide workpiece clamping structure, facilitate in the timber process clamping between the workpiece of each model.
Purpose of the present invention is achieved through the following technical solutions:
Workpiece clamping structure, comprise linking arm, an end at linking arm is provided with fixed bar, be set with the catch bar and the backstay that are free to slide along fixed bar on fixed bar, end at fixed bar is provided with screw shell, and the axis of screw shell is parallel with the axis of linking arm, is set with screw rod in screw shell, be provided with a plurality of locating holes on linking arm, also comprise be used to the pin that is arranged in locating hole.By catch bar, positioning arm cover are contained on linking arm, be provided with screw shell on fixed bar, at screw shell inner sleeve loading screw, rotating screw bolt can make screw rod move with respect to linking arm in sleeve, the end of screw rod drives the catch bar motion, pin inserts the locating hole on linking arm, define the position of backstay, workpiece is placed between catch bar and backstay, rotation by screw rod, can realize catch bar and backstay to the clamping of workpiece, change the insertion position of pin, namely applicable to the clamping of the workpiece of different size.
The end that described screw rod is positioned at outside fixed bar is provided with along screw rod through hole radially, is set with in this through hole and turns round arm, and the described diameter of arm of turning round is less than the aperture of through hole.Further, for the ease of the rotation of screw rod, be provided with through hole at the end of screw rod, this through hole is along the diametric(al) of screw rod and run through screw rod, is set with in through hole and turns round arm, by increasing the arm of force of rotating screw bolt, has reached the purpose that reduces twisting resistance.
Be provided with at the described two ends of turning round arm and block, the diameter of blocking is greater than the aperture of through hole.Further, in order to guarantee that turning round arm can be free to slide in through hole, be provided with diameter at the two ends of turning round arm greater than the blocking of through-hole diameter, so, turning round arm can be free to slide along through hole in through hole, can be unlikely to break away from through hole under the restriction effect of blocking again simultaneously.
Be provided with grip block at described catch bar and backstay end, the width of grip block is greater than the width of catch bar and backstay, and grip block be positioned at screw rod under.The pressure that is subject in order to reduce workpiece adopts the mode that grip block is set to increase contact area, has effectively protected the safety of workpiece.
The present invention compared with prior art has following advantage and beneficial effect:
1 workpiece clamping structure of the present invention, by with catch bar, positioning arm cover is contained on linking arm, be provided with screw shell on fixed bar, at screw shell inner sleeve loading screw, rotating screw bolt can make screw rod move with respect to linking arm in sleeve, the end of screw rod drives the catch bar motion, pin inserts the locating hole on linking arm, define the position of backstay, workpiece is placed between catch bar and backstay, rotation by screw rod, can realize that catch bar and backstay are to the clamping of workpiece, change the insertion position of pin, applicable to the clamping of the workpiece of different size simultaneously namely, its volume is little, simple to operate, safe and reliable,
2 workpiece clamping structures of the present invention, end at screw rod is provided with through hole, this through hole is along the diametric(al) of screw rod and run through screw rod, be set with in through hole and turn round arm, by increasing the arm of force of rotating screw bolt, reached the purpose that reduces twisting resistance, be provided with diameter blocking greater than through-hole diameter at the two ends of turning round arm, so, turning round arm can be free to slide along through hole in through hole, can be unlikely to break away from through hole under the restriction effect of blocking again simultaneously;
3 workpiece clamping structures of the present invention adopt the mode that grip block is set to increase contact area, have effectively protected the safety of workpiece.
