Embodiment Construction

[0032] specific implementation

[0033] Such as Figure 1-19 As shown, a three-degree-of-freedom fine-tunable automatic grabbing device of the present invention, wherein figure 1 It is a schematic diagram of the overall structure of the three-degree-of-freedom fine-tunable automatic grabbing device. Its structure is composed of three parts: the z-direction slide table 1, the x-direction slide table 3, and the y-direction mechanical arm 2. The structure of the x-direction slide table 3 is obtained by removing the anchor bolt mounting block 16 from the z-direction slide table 1 .

[0034] Such as figure 2 As shown, two threaded holes are drilled at the bottom of the positioning rod fixing seat 10, which are connected with the support plate 17 by set screws. The support plate 17 is fixedly connected with the anchor bolt installation block 16 by bolts, and the anchor bolt installation block 16 is fixed on the ground by screws. The connecting plate 112 of the mechanical arm co...

Abstract

The invention provides a three-degree-of-freedom fine-adjustment automatic grabbing device. The device comprises a z-direction sliding table, an x-direction sliding table and a y-direction mechanical arm. The z-direction sliding table comprises a first lead screw, a first lead screw nut, a supporting plate, positioning rods and a positioning rod fixing seat; the structural composition of the x-direction sliding table is the same as that of the z-direction sliding table; the y-direction mechanical arm comprises a y-direction sliding table device, a guide block, a supporting side base, a fine adjustment device, a mechanical gripper device and a power device; and the fine adjustment device comprises a cylinder, a cylinder piston rod, a first connecting rod, a second connecting rod, a third connecting rod and a fixing plate, the cylinder piston rod is connected with the middle of the second connecting rod, the two ends of the second connecting rod are connected with the first connecting rod and the third connecting rod correspondingly, and the fixing plate is used for fixing guide rods. The three-degree-of-freedom fine-adjustment automatic grabbing device is simple in structure, low in cost and high in flexibility and is provided with the fine adjustment device.

Description

technical field [0001] The invention belongs to the technical field of mechanical equipment, and in particular relates to a three-degree-of-freedom fine-tunable automatic grabbing device. Background technique [0002] With the rapid development of industrial automation, automatic grabbing devices are widely used in various production fields to replace human heavy labor and realize mechanization and automation of production. There are many types of automatic grabbing devices, and most of them are manipulators. Multi-degree-of-freedom manipulators can grasp objects in any position and orientation in space, but industrial manipulators are expensive and costly to maintain, and are not suitable for the production needs of small and medium-sized enterprises. Aiming at the current development situation, the present invention designs a three-degree-of-freedom fine-adjustable automatic grabbing device, which has a simple structure and low cost, and can realize simple grabbing and tr...
