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 beneficial effects of the utility model are: one end workpiece pressing extended outside the base by pressing plate; By thrust unit one end and roller contact, under the impetus of cylinder, thrust unit 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; 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; Because movable block often moves up and down along screw mandrel, wearing and tearing are comparatively serious, adopt wear-resistant metal material, can extend its service life.
Accompanying drawing explanation
By the detailed description below in conjunction with accompanying drawing, aforesaid and other object, the feature and advantage of the utility model will become apparent.
Wherein: Fig. 1 is the utility model structural representation;
In accompanying drawing, 1 is motor, and 2 is power transmission shaft, and 3 is bevel gear steering box, and 4 is base, and 5 is screw mandrel, 6 is movable block, and 7 is support, and 8 is pressing plate, and 9 is roller, and 10 is expansion link, and 11 is lock-screw, 12 is cylinder, and 13 is trapezoidal pushing block, and 14 is inclined-plane, and 15 is guide pad, and 16 is guide rail.
Detailed description of the invention
Shown in Figure 1, novel can automatic clamping fixture, comprise base, described base side is provided with thrust unit, and opposite side is provided with hold down gag; Described base is connected with lowering or hoisting gear away from the side of pressing plate external part; Described lowering or hoisting gear comprises motor 1, the power transmission shaft 2 that motor driving shaft free end connects; Described power transmission shaft is connected with bevel gear steering box 3 away from one end of motor, this bevel gear steering box end face connection wire rod 5, and screw mandrel is provided with the movable block 7 (described wear-resistant metal material can adopt stainless steel or potassium steel) of wear-resistant metal material; Described hold down gag comprises support 8, and cantilever tip connects rotatable pressing plate; Described pressing plate is provided with roller 9 near thrust unit one end, and the other end extends outside the base; Described thrust unit comprises the cylinder 12 be arranged on base, and the trapezoidal pushing block 13 that Telescopic-cylinder end connects; The inclined-plane 14 of described trapezoidal pushing block and roller contact; 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 10; Described base is provided with the lock-screw 11 of fastening expansion link.
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); 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; Because movable block often moves up and down along screw mandrel, wearing and tearing are comparatively serious, adopt wear-resistant metal material, can extend its service life.
Embodiment 2
