Description

Automatic lifting pressing clamp
Technical field
The present invention relates to mechanical fixture technology field, particularly relate to automatic lifting pressing clamp.
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 frocks such as combination briquetting to carry out clamping; But the mode of above-mentioned fixation workpiece exists following point: 1) manual operation error, and pressing plate does not press tightly, adding man-hour, workpiece movable, causing producing waste product; 2) when the workpiece that clamping height is different, need to repeat to change different bolts, add the production time.
Summary of the invention
The object of this invention is to provide one to press-fit firmly, and adjustable for height automatic lifting pressing clamp.
Technical scheme of the present invention is as follows:
Automatic lifting pressing clamp, comprises base, and described base side is provided with thrust unit, and opposite side is provided with hold down gag; Described thrust unit, between hold down gag and base, be provided with lowering or hoisting gear; Described hold down gag comprises support, and cantilever tip connects rotatable pressing plate; Described pressing plate is provided with roller near thrust unit one end, and the other 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; Described screw mandrel is provided with movable block, and this movable block is connected with base side wall.
Described thrust unit comprises the cylinder be arranged on base, and the trapezoidal pushing block that Telescopic-cylinder end connects; The inclined-plane of described trapezoidal pushing block and roller contact.
Described thrust unit comprises the oil cylinder be arranged on base, and the trapezoidal pushing block that oil cylinder telescopic end connects; The inclined-plane of described trapezoidal pushing block and roller contact.
Guide pad is provided with between described base and trapezoidal pushing block.
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 trapezoidal pushing block and roller contact, under the impetus of cylinder, trapezoidal pushing block is by the roller jack-up of the side of being located thereon; Because pressing plate is rotatably connected on support, in roller jack-up process, pressing plate opposite side then presses down, thus realizes the automation to the compression of workpiece; 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.
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 roller, and 5 is motor, and 6 is power transmission shaft, and 7 is bevel gear steering box, and 8 is screw mandrel, and 9 is movable block, and 10 is cylinder, and 11 is trapezoidal pushing block, and 12 is guide pad, and 13 is guide rail.
Detailed description of the invention
Shown in Figure 1, automatic lifting pressing clamp, comprises base 1, and described base side is provided with thrust unit, and opposite side is provided with hold down gag; Described thrust unit, between hold down gag and base, be provided with lowering or hoisting gear; Described thrust unit comprises the cylinder 10 be arranged on base, and the trapezoidal pushing block 11 that Telescopic-cylinder end connects; The inclined-plane of described trapezoidal pushing block and roller contact; Described hold down gag comprises support 2, and cantilever tip connects rotatable pressing plate 3; Described pressing plate is provided with roller 4 near thrust unit one end, and the other end extends outside the base; Described lowering or hoisting gear comprises motor 5, the power transmission shaft 6 that motor driving shaft free end connects; Described power transmission shaft is connected with bevel gear steering box 7 away from one end of motor, this bevel gear steering box end face connection wire rod 8; Described screw mandrel is provided with movable block 9, and this movable block is connected with base side wall.
One end workpiece pressing extended outside the base by pressing plate; By trapezoidal pushing block and roller contact, under the impetus of cylinder, trapezoidal pushing block is by the roller jack-up of the side of being located thereon; Because pressing plate is rotatably connected on support, in roller jack-up process, pressing plate opposite side then presses down, thus realizes the automation to the compression of workpiece; 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).
Embodiment 2
Described thrust unit comprises the oil cylinder be arranged on base, and the trapezoidal pushing block that oil cylinder telescopic end connects; The inclined-plane of described trapezoidal pushing block and roller contact.Cylinder is replaced to oil cylinder, effectively can reduce and take up room.
Embodiment 3
Guide pad 12 is provided with between described base and trapezoidal pushing block.Because trapezoidal pushing block will move forward a segment distance, in order to avoid the problem that trapezoidal pushing block glides due to support force deficiency, guide pad is set and provides a support force upwards to trapezoidal pushing block.
Embodiment 4
The described bevel gear steering box back side is provided with guide rail 13; 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.
