Embodiment Construction
[0027] The present invention will be further described below by way of example.
[0028] Such as Figure 2 ~ Figure 4 As shown, the four corners of the column mounting surface of the CNC machine tool used to fix the column 1 and the bed 2 are respectively provided with adjusting screw holes penetrating the column mounting surface, and the adjusting screw holes are located near the connecting screw holes; Glue injection hole 6, the glue injection hole 6 is a horizontal "L" shape, one end is set on the side of the column 1, and the other end is set on the bottom surface of the column 1; The rubber pad 5.
[0029] Assembly method: First, install four adjusting screws 3 to the four adjusting screw holes, the front end of the adjusting screw 3 is located in the adjusting screw hole, and stick a piece of grease to the lower end of each adjusting screw hole. A suitable steel ball 7, and then use a measuring tool to adjust the steel ball to a certain height beyond the mounting surfa...

The invention discloses a method for bonding a body and a column of a numerical control machine tool, which comprises the following steps: (1) punching adjusting screw holes at a connecting part of the column and the body positioned on the column, and arranging adjusting screws; (2) punching injection holes on the column; (3) bonding a steel ball at the lower end of each of the adjusting screws in the adjusting screw holes, and adjusting the steel ball to expose part of the steel ball out of the adjusting screw hole; (4) lifting the column on the body to make the steel ball press on the body, and arranging all connecting screws of the column and the body; (5) adjusting the adjusting screws to make the geometric accuracy among the column, a spindle box and a worktable of the numerical control machine tool meet the standard of working requirement; (6) injecting a bonding agent through the injection holes to ensures that the bonding agent completely fills the space between the column and the body; and (7) standing the column in situ until the bonding agent fully cures, and tightening all the connecting screws by required torque. The method has the advantages for shortening assembly time, reducing labor intensity and improving production efficiency.
Description
technical field [0001] The invention relates to an assembling method of a numerically controlled machine tool, in particular to a glue-filling and bonding method for assembling a bed and a column of a numerically controlled machine tool. Background technique [0002] In the existing CNC machine tool assembly, the connection between the bed and the column is as follows: figure 1 . It ensures the rigidity of the connection between the column and the bed by scraping the contact points between the bed and the column, as well as the geometric accuracy requirements between the column, the headstock and the worktable, because the materials of the column and the bed are cast iron, The fundamental factor affecting the connection rigidity is the size of the actual contact area, any method of increasing the actual contact area can effectively improve the connection rigidity. On the joint surface of the bed column of the machine tool, the contact points on the joint surface are usuall...
