Up-down clamping mechanism

Abstract

The invention relates to an up-down clamping mechanism, and belongs to the technical field of mechanical automation. The clamping device comprises a support, a sliding device, an upper clamping jaw device, a lower clamping jaw device and a power device. The sliding device is slidably mounted on the bracket; the sliding device is provided with a transverse plate and a vertical plate; the upper clamping jaw device is provided with an upper clamping jaw and slidably installed on the vertical plate, and the lower clamping jaw device is provided with a lower clamping jaw and slidably installed on the transverse plate. The sliding device is driven by the power device to slide between the material taking station and the material placing station in a reciprocating mode in the radial direction. At the material taking station, the upper clamping jaw device is driven by the power device to slide on the vertical plate in the radial direction, and the upper clamping jaw is driven to slide towards the upper end of the product; the lower clamping jaw device is driven by the power device to slide on the transverse plate in the horizontal direction, drives the lower clamping jaw to slide towards the lower end of a product and is matched with the upper clamping jaw to clamp the product, then the lower clamping jaw device slides to a discharging station in the radial direction through the sliding device, the product is released through the upper clamping jaw and the lower clamping jaw, and clamping and transferring work of the product is completed.

Description

technical field [0001] The application relates to an upper and lower clamping mechanism, which belongs to the technical field of mechanical automatic production. Background technique [0002] The transfer processing of products is the first link of automatic production. Various mechanical fixtures replace manual handling of products, which is the basic part of realizing mechanical automatic production. [0003] In the existing traditional mechanism, the clamping of the product is generally carried out by a cylinder, and the clamping jaws are driven by the cylinder to perform relative movement for clamping. In this type of clamping method, the clamping force is generated by the driving force of the cylinder, and the clamping force is small. The clamping direction is generally front and rear or left and right relative movement for clamping, and for products that need to be clamped in the up and down direction, a special mechanism needs to be added to achieve this, which resul...

AI Technical Summary

Problems solved by technology

This type of mechanism has a long operating cycle and low production efficiency

Since the relative movement of the upper and lower jaws is synchronous, it is only suitable for products with a symmetrical structure up and down.

For products with asymmetrical shapes, during the clamping process of this type of mechanism, the jaws will drive the product to shift, resulting in unstable clamping
