Abstract
The utility model relates to a drive mechanism with a plurality of connecting rods. The drive mechanism is characterized by comprising a connecting rod and a triangular block, wherein three corners of the triangular block are respectively connected with a fixing support point and one ends of the two connecting rods, and the other ends of the two connecting rods are respectively connected with a drive rod and a sliding block. Since one of the three connecting rods adopts the triangular block, the connecting points of the connecting rods are respectively connected with the triangular block from being connected by three shafts, and therefore, the drive mechanism has simple structure, excellent force and wide design scope of the connecting rod.
Description
Technical field:
The utility model relates to a kind of bar-link drive, particularly a kind of many bar-link drive.
Background technique:
Bar-link drive is widely used in the various field of mechanical technique.As the crank-connecting rod driving mechanism of motor, it is a kind of driving mechanism that power is become circular movement by straight line motion by connecting rod and crank.It is simple in structure, comes down to a kind of two bar-link drive.Ordinary press becomes straight line pressure by two bar-link drive with circumference power.Along with the design of the actuating motor application on press machine, particularly large-scale servo-pressing machine, require its driving mechanism not only simple in structure, energy-efficient performance is good, driving efficient height, but also require according to actual use condition, outfit reaches optimum pressure and forms curve.By retrieval, have a kind of in Japanese publication the servo-pressing machine of patent, its driving mechanism is three bar-link drive.It is a kind of bar-link drive that is interconnected by three (a, b, c), as shown in Figure 4, though it is applied on the servo-pressing machine and can drives and bear bigger driving force with 2,4 even more a plurality of three such linkage mechanisms, because rod connection point connects together by three, it is complicated that structure becomes, axle will be done longlyer, thereby stressed poor, as bearing bigger driving force, certainly will the overstriking connecting rod, can make that mechanism is huge.In addition, the link design narrow range, the curve adjustment range is narrow, and pressure forms curve can not give full play to performance.
Summary of the invention:
The purpose of this utility model be to provide a kind of simple in structure, energy-efficient performance good, drive the efficient height, can be equipped with according to actual use condition reach many bar-link drive that optimum pressure forms curve.。
The technical solution of the utility model is: a kind of many bar-link drive is characterized in that: be made of connecting rod and gore, the triangle of gore is connected and fixed an end of fulcrum and two connecting rods respectively, and the two ends in addition of two connecting rods connect driveshaft and slide block respectively.
Described gore is acute angle or obtuse angle or right-angled triangle piece.
The utility model is owing to adopt gore with a connecting rod in three bar-link drive, rod connection point connects together to become respectively by three and is connected with gore, thereby it is simple in structure, stressed good, the link design scope is wide, the curve adjustment range is wide, and pressure forms curve can give full play to performance.
Description of drawings:
Fig. 1 is the utility model driving structure schematic representation;
Fig. 2 is a vertical drive type schematic representation;
Fig. 3 is the horizontal electric field type schematic representation;
Fig. 4 is three bar-link drive in a kind of servo-pressing machine.
Among the figure: 1, driveshaft; 2, connecting rod; 3, gore; 4, connecting rod; 5, slide block.
Embodiment:
As shown in Figure 1, the utility model is made of connecting rod 2, gore 3, connecting rod 4, one end of connecting rod 2 and driveshaft 1 are connected in the D point, the other end connects gore in the C point, gore and fixed support are connected in the A point, the tie point B of gore is connected with connecting rod 4, and the other end of connecting rod 4 connects slide block 5 in the E point.
As shown in Figure 2, bar-link drive of the present utility model is installed on the servo-pressing machine, be the vertical drive type, its bar-link drive is two, one end of the connecting rod 2 of bar-link drive connects the vertical drive nut of servo-pressing machine, the other end connects a jiao of gore, and an end of connecting rod 4 connects a jiao of gore, and the other end connects slide block.Leg-of-mutton third angle is connected with fixed support on the body.
As shown in Figure 3, bar-link drive of the present utility model is installed on the servo-pressing machine, is horizontal electric field type.Its bar-link drive is two, and an end of the connecting rod 2 of bar-link drive connects horizontal drive nut, and the other end connects leg-of-mutton one jiao, and an end of connecting rod 4 connects a jiao of gore, and the other end connects slide block.Leg-of-mutton third angle is connected with fixed support on the body.
Claims (2)
1. bar-link drive more than a kind, it is characterized in that: be made of connecting rod and gore, the triangle of gore is connected and fixed an end of fulcrum and two connecting rods respectively, and the two ends in addition of two connecting rods connect driveshaft and slide block respectively.
2. many bar-link drive according to claim 1 is characterized in that: described gore is acute angle or obtuse angle or right-angled triangle piece.
