Mark printing device for inner walls of U-shaped parts

Abstract

The invention relates to a mark printing device for inner walls of U-shaped parts. The mark printing device comprises an operating platform and a driving shaft. A support plate is arranged on the operating platform, a first sliding groove and a second sliding groove are formed in the support plate, a first mark printing tube and a second mark printing tube are slidably connected into the first sliding groove and the second sliding groove respectively, a protrusion block is arranged in the middle of each of the first mark printing tube and the second mark printing tube, a rotating shaft is arranged on the support plate, and is located between the first sliding groove and the second sliding groove, a driving plate is connected to the rotating shaft coaxially, a first driving groove and a second driving groove are formed in the driving plate, the protrusion blocks are connected into the first driving groove and the second driving groove in a sliding manner. A first connection rod is fixedly connected to the driving shaft, a second connection rod is connected to the other end of the first connection rod rotationally, the other end of the second connection rod is connected to the protrusion block of the first mark printing tube rotationally; an airbag is fixedly connected to the support plate fixedly, an air cylinder, directly facing the airbag, is arranged on one side of the airbag, an air guide tube is connected between the air cylinder and the airbag. The mark printing device has the advantages that additional fixtures are not needed, and convenience in operation is achieved.

Description

technical field [0001] The invention relates to the field of mechanical processing, in particular to a marking device on the inner wall of a U-shaped part. Background technique [0002] Mechanical parts (machine element), also known as mechanical components, are the basic components that constitute machinery, and are inseparable individual parts that make up machinery and machines. Mechanical parts are mainly divided into different types according to the processing accuracy: 1. Used for precision mechanical parts, which require high coordination stability; 2. Used for ordinary precision mechanical parts, which require high coordination stability; 3. Used for For general mechanical parts, the wear limit of mechanical parts is required not to exceed 50% of the dimensional tolerance value. General mechanical parts can be divided into plate parts, pipe parts, ring parts, U-shaped parts and special-shaped parts according to the different processing shapes. [0003] Mechanical p...
