Description
Technical field
The present invention relates to mechanical fixture technology field, particularly relate to height adjustable frock.
Background technology
Before milling workpiece, need workpiece to fix on the table at present on milling machine; The mode of current fixation workpiece generally adopts the fixtures such as combination briquetting to carry out clamping; But there is following point in the mode of above-mentioned fixation workpiece: when 1) adopting combination briquetting, owing to being generally pushed down by workpiece by the cooperation of bolt and pressing plate manually, add man-hour at part in enormous quantities, need repeatedly to press-fit, waste time and energy; 2) when operating personnel are firmly excessive, the surface that workpiece pushed down by briquetting there will be wearing and tearing, causes workpiece surface quality poor.
Summary of the invention
The object of this invention is to provide one and be convenient to clamping, and the height adjustable frock that workpiece surface quality is good.
Technical scheme of the present invention is as follows:
Height adjustable frock, comprises base, and described base side is provided with hold down gag; Lowering or hoisting gear is provided with between described hold down gag and base; Described hold down gag comprises support, the affixed horizontal pressing plate of cantilever tip; Described pressing plate one end extends outside the base; Described lowering or hoisting gear comprises motor, the power transmission shaft that motor driving shaft free end connects; Described power transmission shaft is connected with bevel gear steering box away from one end of motor, this bevel gear steering box end face connection wire rod, and screw mandrel is provided with movable block; Retractor device is provided with between described base and lowering or hoisting gear; Described retractor device comprises the square groove be arranged on base contacts face, and be arranged on movable block with square groove with the use of expansion link; Described base is provided with the lock-screw of fastening expansion link.
The described bevel gear steering box back side is provided with guide rail; The described movable block back side be provided with guide rail with the use of groove.
The invention has the beneficial effects as follows: one end workpiece pressing extended outside the base by pressing plate; By arranging lowering or hoisting gear, making the adjustable of hold down gag height, realizing when workpiece height is higher, also can to higher Work-sheet pressing; Due to the variation of processing parts shape, when the stairstepping boss class workpiece that structure is comparatively complicated needs to press-fit width less top, due to pressing plate limited length, press-fit comparatively difficulty, and by arranging retractor device, thus the lateral separation of adjusting base, indirectly implement the adjustment of pressing plate lateral length, thus make to be convenient to carry out clamping to stairstepping boss class workpiece; After base is adjusted to suitable lateral length, by lock-screw, expansion link is locked.
Accompanying drawing explanation
By the detailed description below in conjunction with accompanying drawing, aforesaid and other object, the feature and advantage of the present invention will become apparent.
Wherein: Fig. 1 is structural representation of the present invention;
In accompanying drawing, 1 is base, and 2 is support, and 3 is pressing plate, and 4 is motor, and 5 is power transmission shaft, and 6 is bevel gear steering box, and 7 is screw mandrel, and 8 is movable block, and 9 is driving shaft, and 10 is deflector roll, and 11 is flange.
Detailed description of the invention
Shown in Figure 1, height adjustable frock, comprises base 1, and described base side is provided with hold down gag; Lowering or hoisting gear is provided with between described hold down gag and base; Described hold down gag comprises support 2, the affixed horizontal pressing plate 3 of cantilever tip; Described pressing plate one end extends outside the base; Described lowering or hoisting gear comprises motor 4, the power transmission shaft 5 that motor driving shaft 9 free end connects; Described power transmission shaft is connected with bevel gear steering box 6 away from one end of motor, this bevel gear steering box end face connection wire rod 7, and screw mandrel is provided with movable block 8; Retractor device is provided with between described base and lowering or hoisting gear; Described retractor device comprises the square groove be arranged on base contacts face, and be arranged on movable block with square groove with the use of expansion link; Described base end face is provided with the lock-screw of fastening expansion link.
One end workpiece pressing extended outside the base by pressing plate; By arranging lowering or hoisting gear, making the adjustable of hold down gag height, realizing when workpiece height is higher, also can (lowering or hoisting gear be by the rotation rotarily driving power transmission shaft of motor driving shaft to higher Work-sheet pressing; Driving force is transferred to screw mandrel by the bevel gear steering box that is rotated through of power transmission shaft, and the movable block rotarily driven on screw mandrel of screw mandrel moves along screw mandrel, thus regulates the height of the base be connected with movable block); Due to the variation of processing parts shape, when the stairstepping boss class workpiece that structure is comparatively complicated needs to press-fit width less top, due to pressing plate limited length, press-fit comparatively difficulty, and by arranging retractor device, thus the lateral separation of adjusting base, indirectly implement the adjustment of pressing plate lateral length, thus make to be convenient to carry out clamping to stairstepping boss class workpiece; After base is adjusted to suitable lateral length, expansion link is locked (lock-screw with the through hole being distributed on expansion link end face with the use of) by lock-screw.
Embodiment 2
The extend outside the base bottom surface of one end of pressing plate is provided with columned flange 11.Due to columned flange, make pressing plate and absorption surface area comparatively large, make pressing plate compress better effects if.
Embodiment 3
The described bevel gear steering box back side is provided with guide rail 10; The described movable block back side be provided with guide rail with the use of groove.By arranging guide rail, avoiding movable block moving up and down in process, rotating.
The present invention is not limited to described embodiment, and those skilled in the art, not departing from spirit of the present invention namely openly in scope, still can do some and revise or change, therefore the scope that the scope of the present invention limits with claims is as the criterion.
