Special-shaped hardware grabbing mechanism based on negative pressure

Abstract

The invention relates to the technical field of hardware grabbing, and discloses a special-shaped hardware grabbing mechanism based on negative pressure. The special-shaped hardware grabbing mechanismbased on negative pressure comprises an operating table; a grabbing seat is fixedly connected to the right side of a lifting platform; a flexible pad is fixedly arranged at the bottom of the grabbingseat; the interior of the flexible pad is filled with powder; an air cylinder is fixedly arranged at the top of the grabbing seat; a piston rod is movably inserted in the inner side of the air cylinder; a tension spring is fixedly arranged between the top of the piston rod and a top plate; and a first toothed plate is fixedly connected to the left side of the piston rod. When the lifting platformmoves downwards, an incomplete gear drives the piston rod through the toothed plate to move downwards along with the lifting platform, after the flexible pad covers the outer side of hardware, the incomplete gear is separated from the first toothed plate, the piston rod moves upwards rapidly under the action of the tension spring, air in the flexible pad is pumped away to form the negative pressure, the powder is extruded and shaped, and then the hardware can be firmly grasped. The special-shaped hardware grabbing mechanism based on the negative pressure can achieve the function of grabbing the special-shaped hardware to another position, and is simple in structure and convenient to use.

Description

technical field [0001] The invention belongs to the technical field of grabbing hardware, and in particular relates to a grabbing mechanism for special-shaped hardware based on negative pressure. Background technique [0002] With the development of industry and technology, more and more hardware equipment is used in people's life. The definition of hardware is relatively broad, which generally refers to metal, including hardware tools and hardware parts. Architectural hardware and daily hardware, etc., with the widening of uses, the shapes of hardware are becoming more and more diverse. Therefore, there are a large number of special-shaped hardware on the market. [0003] During the production of hardware, it needs to go through many processes such as cutting, polishing, spraying, etc., and the same is true for special-shaped hardware. Therefore, in the process of manufacturing, it is necessary to continuously grab and move the hardware from one processing place to another....

Problems solved by technology

[0003] During the production of hardware, it needs to go through many processes such as cutting, polishing, spraying, etc., and the same is true for special-shaped hardware. Therefore, in the process of manufacturing, it is necessary to continuously grab and move the hardware from one processing place to another. In the processing place, the traditional hardware fixture has a simple structure, and it is more reliable for grasping regular-shaped hardware, but for special-shaped hardware, it will not be firmly grasped.
