Abstract
The invention relates to a self-positioning fixture. The self-positioning fixture comprises a U-shaped seat frame body [11], a lifting device and a clamping device, wherein the lifting device comprises a screw [8], a nut [7], two carrier rods and a carrier rod seat; one end of the screw [8] is fixedly connected to the middle of the seat frame body [11]; on the carrier rod seat, two transverse rods [9] are fixedly connected to the two side faces of a shaft sleeve [6] symmetrically; the shaft sleeve [6] is sleeved on the screw [8]; a through hole is formed on the two sides of the seat frame body [11] respectively; the two carrier rods are positioned in the through holes; the two transverse rods [9] are connected with the lower ends of the two carrier rods respectively; the clamping device comprises two clamping blocks [5] and two rotating levers [3]; the two clamping blocks [5] are fixedly connected to the upper ends of the two carrier rods respectively; and each clamping block is hinged with one end of each rotating lever [3], and the other end of each rotating lever [3] is hinged with the upper parts of the two sides of the seat frame body [11]. The self-positioning fixture can clamp and position workpieces, so machining accuracy and machining efficiency are greatly improved.
Description
Technical field
The present invention relates to a kind of anchor clamps, 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.
Summary of the invention
Purpose of the present invention just provides a kind of anchor clamps that can be self-align, improves machining accuracy and efficiency.
The technical solution used in the present invention 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 invention has the beneficial effects as follows: because the present invention 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 present invention, 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.
