Air detection heavy-duty floating support

Abstract

The invention relates to an air detection heavy-duty floating support. The lower part of a floating support base is provided with a semicircular slot block. A floating positioning block is of a semicylinder shape. The shape and the size of the floating positioning block are matched with the shape and size of the semicircular slot block. The semicircular slot block is provided with a waist-shaped hole. The upper end face of the floating positioning block is provided with a threaded blind hole. A screw is arranged in the threaded blind hole. The screw perforates through the waist-shaped hole and can slide in the waist-shaped hole. The bottom surface of the floating positioning block is provided with a chip blowing hole. The chip blowing hole is communicated with an air tube. The other end of the air tube is provided with an air pressure sensor. The air pressure sensor is connected with an air source. In the invention, an electromagnetic on-off valve can be arranged between the air pressure sensor and the air source; and the air pressure sensor is connected to a programmable logic controller capable of receiving a signal of the air pressure sensor and sending a command for controlling the electromagnetic on-off valve to actuate. Compared with the prior art, the air detection heavy-duty floating support has the beneficial effects that the air detection heavy-duty floating support has high rigidity, is suitable for heavy-duty cutting and can also be used for cleaning chips adhered to a positioning surface through blowing air and detecting whether the chips are adhered to the positioning surface so as to prevent a clamp from working by mistake.

Description

technical field [0001] The invention relates to a component in the field of mechanical processing, in particular to a floating support structure for an automatic displacement hydraulic clamp for processing a composite angle rear cantilever. Background technique [0002] As a positioning element, the floating support is mainly used on the fixture that needs to automatically adjust the position during the positioning process of the workpiece. It is often used in the occasion where the workpiece is positioned on the blank surface or the rigidity is insufficient. Commonly used floating supports are two-point or three-point floating supports, and the support points are made of reticulated, spherical, etc. Because these commonly used structures are point contacts, the rigidity is poor, and the positioning accuracy and repeat positioning accuracy are also relatively low. , the sticky debris on the positioning surface cannot be automatically cleaned and detected.
