Embodiment Construction

[0014] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0015] like Figure 1 to Figure 5 As shown, the whole mechanism is composed of two linkage mechanisms symmetrical to the main beam, and the two linkage mechanisms share a set of main shafts. Therefore, by arranging the two linkage mechanisms in two parallel horizontal planes Realize its symmetry, so the two symmetrical link mechanisms have a certain height difference, so the manipulator sliders with different heights are used so that the manipulator mounting surface of the entire spacing synchronous adjustment mechanism is in the same plane.

[0016] The power source of the system is the double-acting cylinder 7, the main beam 1 is used as the frame of the whole mechanism, and the expansion guide rail 6 is installed under the main beam 1, which is parallel to the axis of the main beam, and the expansion slider 5 cooperates with it, which can ex...

Abstract

The invention discloses a single-driving equal-interval synchronous extending mechanism, and belongs to the field of mechanical automation equipment. The single-driving equal-interval synchronous extending mechanism comprises a power source and an extending device, a main beam serves as a rack of the whole mechanism, an extending guide rail is arranged on the main beam, an extending sliding block cooperates with the extending guide rail, a buffering device is arranged on the main beam, one end of a head extending connecting rod is hinged to the extending sliding block, the other end of the head extending connecting rod is connected with a rocker arm, a main shaft is designed to be a fixed shaft, the rocker arm cooperates with the main shaft through a knuckle bearing, the rocker arm is hinged to extending rods and guide rail rods, mechanical arm sliding blocks are arranged on the guide rail rods to move along the axial direction on the guide rail rods, four guide rail rods are arranged on the mechanism, four mechanical arm sliding blocks which are arranged in one row are arranged on each guide rail rod and are connected through interval control belts, one end of a mechanical arm sliding block array is fixed on the guide rail rod, and the other end of the mechanical arm sliding block array is hinged to the extending rod. The system applies the single power source. The single-driving equal-interval synchronous extending mechanism is reasonable in structure, and easy and simple to control.

Description

technical field [0001] The invention relates to a distance adjusting mechanism, in particular to a mechanism for synchronously extending equal distances between two positions. Background technique [0002] The distance expansion mechanism is widely used in the field of mechanical equipment, especially in agricultural machinery, packaging machinery and the like. The motion precision and speed of the pitch expansion mechanism are important factors affecting the working efficiency of the machine. [0003] The main types of existing spacing adjustment mechanisms include screw nut mechanisms driven by motors and rack and pinion mechanisms, cylinder push rod sliding mechanisms driven by air cylinders and hydraulic cylinders, and some sliding auxiliary mechanisms. Most of the above-mentioned spacing adjustment mechanisms are only used for spacing adjustment between two workpieces or a single row of workpieces. However, there is still a lack of a specific and practical mechanism f...
