Abstract
The utility model discloses a self-positioning clamp, comprising a U-shaped seat frame body (11), a lifting device and a clamping device, wherein the lifting device comprises a screw rod (8), a nut (7), two ejector rods and an ejector rod seat, wherein one end of the screw rod (8) is fixedly connected with the center of the seat frame body (11); the ejector rod seat is that two sides of a shaft sleeve (6) are symmetrically and fixedly connected with two cross rods (9), and the shaft sleeve (6) is sleeved on the screw rod (8); the two sides of the seat frame body (11) are respectively provided with a through hole; the two ejector rods are positioned in the through holes; the two cross rods (9) are respectively connected with the lower ends of the two ejector rods; the clamping device comprises two clamping blocks (5) and two rotating levers (3); the two clamping blocks (5) are respectively fixedly connected with the upper ends of the two ejector rods, each clamping blocks is hinged with one end of the rotating lever (3), and the other ends of the rotating levers (3) are hinged with the upper parts of the two sides of the seat frame body (11). The utility model not only can clamp, but also can position, thus greatly improving the machining precision and machining efficiency.
Description
Technical field
The utility model relates to a kind of anchor clamps, and is especially a kind of to can self-align anchor clamps.
Background technology
Anchor clamps use very extensive in factory.The function of anchor clamps is to fix to machined part, again machining.The shape of workpiece is varied, so the structure of anchor clamps is also varied.Often run into L-shaped workpiece or bar-shaped workpieces in the factory and need be clamped in punching or other processing on the side, though existing anchor clamps have the clamping function, but could process after often needing it is positioned,, therefore after the processing bigger deviation often be arranged because anchor clamps do not have self-locating function.Simultaneously, in position fixing process, need spended time, therefore also greatly reduce working (machining) efficiency.
The utility model content
The purpose of this utility model just provides a kind of anchor clamps that can be self-align, improves machining accuracy and efficiency.
The technical solution adopted in the utility model is:, a kind of self-align anchor clamps, it is characterized in that it comprises U type base frame body, lowering or hoisting gear and clamping device, described lowering or hoisting gear comprises screw rod, adaptive and be connected in the nut on the screw rod, left push rod, right push rod and tip-lever support with screw rod, screw rod one end is fixed in the central authorities of base frame body, tip-lever support is that axle sleeve two sides symmetry is fixed with two cross bars, axle sleeve is sleeved on the screw rod, and nut is connected on the screw rod of axle sleeve bottom; Establish the both sides of base frame body respectively through hole, and two push rods lay respectively in the through hole, and can slide up and down along through hole, and two cross bars are connected with two push rod lower ends respectively, makes tip-lever support rise and drives the rising of two push rods; Described clamping device comprises two clamps and two rotating levers, and two clamps are fixed in the upper end of push rod respectively, and each clamp and rotating lever one end are hinged, the rotating lever other end and base frame body both sides upper articulation.
Adopt technique scheme, during clamping work pieces, workpiece is placed in the base frame body, rotating nut, nut rise along screw rod and promote the tip-lever support rising, and tip-lever support rises and rises by push rod promotion clamp, clamp is in uphill process, because the promotion of rotating lever is moved to the center, two clamps will be clamped workpiece, thereby reach the purpose of clamping.Because the clamp moving displacement is identical, therefore also reach simultaneously the purpose of location centering.
In sum, the beneficial effects of the utility model are: because the utility model both can clamp, in clamping process, realize the location simultaneously, therefore improved the precision of processing work, improved working (machining) efficiency.

The specific embodiment
A kind of self-align anchor clamps of the utility model, as shown in Figure 1, it comprises U type base frame body 11, lowering or hoisting gear and clamping device.
Described lowering or hoisting gear comprises screw rod 8, adaptive and be connected in nut 7, left push rod 12, right push rod 10 and tip-lever support on the screw rod 8 with screw rod 8, screw rod 8 one ends are fixed in the central authorities of base frame body 11, tip-lever support is that axle sleeve 6 two sides symmetries are fixed with two cross bars 9, axle sleeve 6 is sleeved on the screw rod 8, and nut 7 is connected on the screw rod of axle sleeve 6 bottoms; The both sides of base frame body 11 respectively are provided with through hole, and two push rods are positioned at through hole, and can slide up and down along through hole, and two cross bars 9 are connected with two push rod lower ends respectively, make tip-lever support rise and drive the rising of two push rods.
Described clamping device comprises two clamps 5 and two rotating levers 3, two clamps 5 are fixed in the upper end of two push rods respectively, each clamp is hinged by bearing pin 4 and rotating lever 3 one ends, and rotating lever 3 other ends are by rotating shaft 2 and base frame body 11 both sides upper articulations.
In the time of in workpiece 1 places base frame body 11, rotating nut 7 can be realized clamping and the location.
