Dial indicator switching device

Abstract

The invention discloses a dial indicator switching device which comprises a spindle connecting rod assembly, a switching rod assembly and a dial indicator connecting rod assembly. The spindle connecting rod assembly comprises a first connecting rod, a first connecting piece and a pressing piece, one end of the first connecting rod is connected with the first connecting piece, and the other end of the first connecting rod is used for being connected with an external boring machine. The pressing piece is rotatably connected to the top of the first connecting piece, and a first fixing hole is formed in the tail. The switching rod assembly comprises a second connecting rod, a second connecting piece and a switching connector, one end of the second connecting rod is clamped in the first fixing hole, and the other end of the second connecting rod is rotatably connected with the switching connector through the second connecting piece; a second fixing hole is formed in the switching connectorr close to the free end; the dial indicator connecting rod assembly comprises a third connecting rod, a third connecting piece and a dial indicator fixing piece, one end of the third connecting rod is clamped in the second fixing hole, and the other end of the third connecting rod is connected with the third connecting piece; and one surface of the third connecting piece, which is vertical to the surface connected with the third connecting rod, is rotatably connected with a dial indicator fixing piece. And the processing efficiency is improved.

Description

technical field [0001] The invention relates to the field of mechanical processing, in particular to a dial gauge transfer device. Background technique [0002] Most of the company's products are large-scale casting shell parts with complex structures and irregular parts. This type of product requires no machining of the inner cavity, and the uneven deformation of the shell after casting makes it difficult to process the shell subsequently. In the process of machining and aligning the datum, there are degrees of freedom in three directions, and the degrees of freedom in the three directions must be restricted at the same time before cutting. [0003] The inner cavity of the shell needs to be processed more complicated, such as milling large planes, small planes, step planes, plane holes, arc surface holes, etc., and the processing parts are different in height, distance, and orientation. Therefore, in the rough machining, it is necessary to carry out the process content suc...
