Abstract
The utility model relates to a multi-connecting-rod drive mechanism, which is characterized by mainly comprising a plurality of connecting rods and a triangular block. The three corners of the triangular block are respectively connected with one ends of a drive rod and two connecting rods, and the other two ends of the two connecting rods are respectively connected with a fixed support point and a sliding block. Since one connecting rod of the three-connecting-rod drive mechanism adopts the triangular block, the connection of three shafts is changed into the connection of the triangular block for connection points of the connecting rods, and the multi-connecting-rod drive mechanism has a simple structure, high bearing capacity and a wide design scope for the connecting rods.
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 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, but, 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, it is characterized in that: mainly constitute by connecting rod and gore, the triangle of gore connects driveshaft respectively, an end of two connecting rods of slide block and fixed support, and the two ends in addition of two connecting rods are connected and fixed fulcrum 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, increased the degrees of freedom of leverage simultaneously, the link design scope is wide, and the curve adjustment range is wide, and pressure forms curve can give full play to performance.
