Description
Technical field
The present invention relates to a kind of wood working tool, specifically refer to the positioning clamping device for low-hardness workpiece.
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 the positioning clamping device for low-hardness workpiece, facilitate in the timber process, blend stop is fixed on the platform of surfacer, determine fast the distance between blend stop and saw blade, i.e. the width of the workpiece, simultaneously, reduce the suffered pressure of workpiece, avoid workpiece to be damaged.
Purpose of the present invention is achieved through the following technical solutions:
the positioning clamping device that is used for low-hardness workpiece, comprise the upper clip arm that connects successively, linking arm, and lower clip arm, the clamping face of upper clip arm and the clamping face of lower clip arm are parallel to each other, linking arm is vertical with the clamping face of upper clip arm, be provided with screw at described lower clip arm away from an end of linking arm, be provided with internal thread in this screw, in this screw, screw rod is installed, the external screw thread of screw surface and the internal thread of screw are complementary, be provided with grip block at described screw rod top, clamping face at described upper clip arm is provided with compression plate, the lower surface of described compression plate is parallel with the upper surface of grip block.by the upper clip arm that connects successively, linking arm, and lower clip arm, consist of the framework of " C " font, screw is set on lower clip arm, the screw rod that is complementary with it is installed in screw, rotation by screw rod, screw rod is along the axially-movable of screw, distance between the grip block at screw rod top and the compression plate of upper clip arm changes by rotary screw, during use, blend stop is prevented putting on the platform of surfacer, make it to be adjacent to the fixedly blend stop of surfacer, be placed on blend stop with the compression plate on the upper clip arm of clamping device, and make grip block on lower clip arm be positioned at compression plate under, and be positioned under the platform of surfacer, rotary screw, dwindle the distance between grip block and compression plate, so just, blend stop can be fixed on platform, be fixed between grip block and compression plate, by increasing the compression area of workpiece, reduced the pressure that blend stop or surface of the work are subject to, avoided wood materials under the effect that is subject to external force and be out of shape, or even damage, increased grip block and surfacer platform the bottom between contact area, reduced the possibility of its slip.
Be provided with in the lower end of described screw rod along screw rod through hole radially, be set with in this through hole and turn round arm, 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 in the bottom 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.
The connecting portion of the connecting portion of described upper clip arm and linking arm and linking arm and lower clip arm all has reinforced company's tape splicing.When the clamping blend stop, in order to increase the chucking power between upper clip arm and screw rod top, overcome the deformation that upper clip arm, lower clip arm produce because being subject to external force, be provided with reinforced company's tape splicing at the connecting portion of upper clip arm and linking arm and the connecting portion of lower clip arm and linking arm.
The present invention compared with prior art has following advantage and beneficial effect:
1 the present invention is used for the positioning clamping device of low-hardness workpiece, rotation by screw rod in screw, can change the distance between screw rod top and upper clip arm, thereby can the adjusting screw(rod) top and upper clip arm between chucking power, namely facilitate the blend stop quick-replaceable of different size, its volume is little, simple to operate, by increasing the compression area of workpiece, reduced the pressure that blend stop or surface of the work are subject to, avoided wood materials under the effect that is subject to external force and be out of shape, or even damage, increased grip block and surfacer platform the bottom between contact area, reduced the possibility of its slip,
2 the present invention are used for the positioning clamping device of low-hardness workpiece, bottom 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 the present invention are used for the positioning clamping device of low-hardness workpiece, at the connecting portion of upper clip arm and linking arm and the connecting portion of linking arm and lower clip arm, reinforced company's tape splicing is arranged all, when the clamping blend stop, increase the chucking power between upper clip arm and screw rod top, overcome the deformation that upper clip arm, lower clip arm produce because being subject to external force.
