Description

Exhaust pipe milling small flange fixture

technical field

The invention relates to mechanical processing equipment, in particular to a small flange fixture for exhaust pipe milling.

Background technique

    Flange is also known as flange or flange. Flanges are parts that connect pipes to pipes and are connected to pipe ends. Flange connection or flange joint refers to the foldable connection of flanges, gaskets and bolts as a combined sealing structure. Pipe flange refers to the flange used for piping in pipeline installations. The above refers to the inlet and outlet flanges of the equipment. Flanges are now used in all walks of life, but there are great difficulties in the installation of flanges. Some sealing flanges have high requirements for installation. There are errors caused by human operation in traditional fixtures. Large, the machining accuracy cannot meet the requirements, and the workpiece installation axis is offset.

Contents of the invention

The present invention provides a small flange fixture for exhaust pipe milling that can accurately install flanges and ensure that the bearings on which the flanges are installed do not deviate.

The present invention solves technical problem and provides following scheme:

A small flange fixture for exhaust pipe milling, comprising a base plate, characterized in that: the left front and rear ends of the base plate are respectively provided with brackets, the upper left sides of the left and right brackets have slopes respectively, and the left and right slopes A fixture plate is fixedly installed between them, and a thin-walled cylinder is fixedly installed on the outer surface of the fixture plate, and a pull rod is fixedly installed on one end of the piston rod of the thin-walled cylinder, and one end of the pull rod passes through the fixture plate and is installed with a pressure plate, The end of the pull rod is provided with a limit nut, and a spring is set on the pull rod, and the spring is pressed between the pressure plate and the clamp plate. The pressure plate can move left and right along with the thin-walled cylinder. The right bottom plate of the bracket A cylinder is fixedly installed, the upper end of the piston rod of the cylinder is equipped with an upper tie rod, the top end of the upper tie rod is covered with an upper pressure plate, the upper surface of the upper pressure plate is provided with a nut on the pull rod, and the upper pull rod is covered with a spring , the upper and lower ends of the spring respectively bear on the upper pressing plate and the cylinder.

A floating support is provided on the bottom plate on the left side of the cylinder, and a top wire is provided at the upper end of the floating support.

In the present invention, brackets are installed at the front and rear ends of the bottom plate, and a clamp plate is arranged between the brackets. The cylinder is fixed on the clamp plate, and the left and right movement of the cylinder drives the pressure plate to adjust the position of the pressure plate, so that the workpiece is installed on the clamp plate. , press it with a pressure plate, adjust the position of the pressure plate above the cylinder on the right side, and then push the jacking wire at the upper end of the floating support to the workpiece to be installed. By adopting the invention, the position deviation of the workpiece installation axis in the installation process can be effectively avoided, resulting in processing failure.
