Description

Woodwork presss from both sides
Technical field
The utility model relates to hand-operated tools, and particularly a kind of woodwork presss from both sides.
Background technology
Woodworker clamp is one of instrument that wood working industry is conventional, also for all conglomeraties such as panel beating, building, decorations.The structure of existing Woodworker clamp is generally be fixedly mounted with fixed arm in one end of a guide rod, is set with handle screw at its other end, by rotary handle screw rod, thus completes and clamps object.
And operationally for increasing work efficiency, needing can the fixture of fast clamp workpiece, and when holding workpiece, also must have certain chucking power, otherwise workpiece easily askew fall, walk, reduce operating accuracy.
More existing carpenters' clamps, mainly utilize the head of screw rod to apply pressure to workpiece, and the head of screw rod is general less, easily makes workpiece leave catcher mark even defective work piece when pressure is larger.In use, can add lastblock backing plate to avoid and produce catcher mark, but can only contact the side of backing plate due to screw rod, backing plate unbalance stress is easy to the workpiece deformation that causes clamping or damage.
Utility model content
The purpose of this utility model is to provide a kind of woodwork folder, to solve the deficiency of existing carpenters' clamp.
According to an aspect of the present utility model, provide woodwork folder, comprising:
Guide rod, guide rod is fixed with screw bar, and screw bar is vertical with guide rod, and screw masthead end is provided with screw;
First arm of force, first arm of force is fixedly connected with guide rod;
Second arm of force, second arm of force is connected with guide rod and can slides along guide rod;
Screw rod, match with screw through screw, screw rod one end contacts mutually with second arm of force, when precession screw rod, screw rod promotes second arm of force and moves to first arm of force along guide rod, thus the Workpiece clamping that will be clamped between first arm of force and second arm of force.
Adopt the woodwork of above technical scheme to press from both sides, by first arm of force and second arm of force by Workpiece clamping, effectively can disperse the pressure clamped, prevent the workpiece compressive deformation clamped.And the stress point of screw rod is positioned at the middle part of second arm of force, make the pressure of second arm of force more even.
In some embodiments, second arm of force is sheathed on guide rod periphery wall.
In some embodiments, guide rod cross section is triangle, quadrangle or hexagon, or is oval or semicircle.Guide rod cross-section center is asymmetric, and second arm of force be sheathed on guide rod cannot rotate along guide rod, uses convenient.
In some embodiments, first arm of force is sheathed on guide rod periphery wall and can slides along guide rod.By the position of mobile first arm of force, the ultimate range between two arm of forces or minimum range can be regulated, make this carpenters' clamp can be used for the article of plurality of specifications.
In some embodiments, guide rod is provided with multiple guide rod hole along its length, and first arm of force is provided with fixing hole, by pin rod or screw or bolt are inserted guide rod hole from fixing hole, thus is fixed on guide rod by first arm of force.
In some embodiments, second arm of force is provided with the accommodating hole for accommodating screw tip, and the top of screw rod is rotated under the restriction of accommodating hole.Can prevent screw rod from coming off from second arm of force thus, make clamping more firm.
In some embodiments, screw rod is also provided with handle, and handle is vertical with screw rod.Thus, screw rod rotates convenient.
Accompanying drawing explanation
Fig. 1 is the woodwork clamping structure schematic diagram of a kind of embodiment of the utility model.
Fig. 2 is the woodwork clamping structure schematic diagram of the another kind of embodiment of the utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Embodiment 1
Fig. 1 show schematically show and presss from both sides according to the woodwork of a kind of embodiment of the present utility model.As shown in the figure, this device comprises: guide rod 1, first arm of force 12, second arm of force 13 and screw rod 2.
Wherein, guide rod 1 cross section is circular, and one end is fixed with screw bar 11.Screw bar 11 is vertical with guide rod 1.Screw bar 1 top is provided with screw 111.
First arm of force 12 is sheathed on guide rod 1 periphery wall and can slides along guide rod 1.Guide rod 1 is provided with multiple guide rod hole 14, first arm of force along its length and is provided with fixing hole 121.By screw 3 is inserted guide rod hole 14 from fixing hole 121, thus first arm of force 12 is fixed on guide rod 1.In other examples, the rod-like articles such as pin rod or bolt can also be used to be fixed on guide rod 1 by first arm of force 12.
Second arm of force 13 is sheathed on guide rod 1 periphery wall, and can slide along guide rod 1.Second arm of force 13 is provided with the accommodating hole 131 for accommodating screw rod 2 top, and the top of screw rod 2 is rotated under the restriction of accommodating hole 131.
Screw rod 2 passes screw 111 and matches with screw 111.Screw rod 2 one end contacts mutually with second arm of force 13.Screw rod 2 is also provided with handle 21, and handle 21 is vertical with screw rod 2.When precession screw rod 2, screw rod 2 promotes second arm of force 13 and moves to first arm of force 12 along guide rod 1, thus the Workpiece clamping that will be clamped between first arm of force 12 and second arm of force 13.
Adopt the woodwork of above technical scheme to press from both sides, by first arm of force 12 and second arm of force 13 by Workpiece clamping, effectively can disperse the pressure clamped, prevent the workpiece compressive deformation clamped.And the stress point of screw rod 2 is positioned at the middle part of second arm of force 13, make the pressure of second arm of force 13 more even.By the position of mobile first arm of force 12, the ultimate range between two arm of forces or minimum range can be regulated, make this carpenters' clamp can be used for the article of plurality of specifications.
Embodiment 2
Fig. 2 show schematically show and presss from both sides according to the woodwork of another kind of embodiment of the present utility model.As shown in the figure, be with the difference of embodiment 1, the cross section of guide rod 1 is quadrangle.
In other implementations, the cross section of guide rod 1 can also be the polygons such as triangle, pentagon or hexagon, or is oval or semicircle.Guide rod 1 can adopt solid bar manufacture, also can use hollow tubing manufacture.Screw bar can also be connected by screw with between guide rod.
Above-described is only embodiments more of the present utility model.For the person of ordinary skill of the art, under the prerequisite not departing from the utility model creation design, can also make some distortion and improvement, these all belong to protection domain of the present utility model.
