Basic concepts and requirements for the structural craftability of cutting machine parts
The four-column cutting machine parts have better structural processability, which means that they can be conveniently and economically produced under certain production conditions, and are easy to assemble into a machine. Therefore, the structural processability of the parts should be considered comprehensively from several production links such as manufacturing, machining and assembly of blanks.
The structural design of the part should first meet the requirements for use. This is the fundamental purpose of designing and manufacturing the part. It is the premise of considering the processability of the part structure. In addition to the required performance of the part, it must proceed from the requirements of process, economy, maintenance and maintenance. The design of the parts is guaranteed to be the least, the cost is the lowest, the manufacturing and assembly are the easiest, and the use, maintenance and maintenance are most convenient.
In the entire manufacturing process of the four-column cutting machine parts, the labor and the consumption of the cutting process are the most used, so the structural requirements of the machining of the parts are particularly important. In order to make the parts have good processability in the cutting process, in addition to meeting the requirements of use, the structural requirements of the cutting machine parts are as follows:
(1) Reasonably select the accuracy and surface roughness of the part. Do not need to machine the surface or the surface that is not required to be high, and do not design it as a machined surface or a high precision machined surface.
(2) It should be able to be positioned accurately, the center is tight and reliable, easy to install and process, and easy to measure. Surfaces with mutual positional accuracy requirements are preferably machined in a single installation to ensure quality.
(3) The structural dimensions of the parts should be standardized and standardized, which makes it easy to use the standard hard tools and general measuring tools to reduce the design and manufacture of special tools and measuring tools.
(4) The geometry of the machined surface should be as simple as possible, as close as possible to the same axis or the same plane, to facilitate processing and increase productivity.
