Technical Field

The invention relates to a processing technology for processing a sealing guide rail of a bottle blowing machine by four-axis linkage.

Background

As a core part of a bottle blowing machine, the sealing guide rail adopts a main processing technology at present that a horizontal processing center swings and angle divides a section to process a guide rail surface, however, in the processing process, the cutter marks formed by processing a processing cutter on the guide rail surface have deviation with the moving track of a roller bearing on the guide rail surface, and in the connection part of the section processing, due to the fact that joint marks exist in processing errors, the roller bearing generates large noise when the sealing guide rail processed by the technology runs at high speed, and the abrasion is very fast.

In order to solve the above problems, it is necessary that the processing track of the tool of the machine tool on the sealing guide surface is consistent with the movement track of the roller bearing on the sealing guide surface, and therefore, the processing can be realized only by the machine tool with four-axis linkage in the prior art. However, the four-axis linkage processing seal guide rail is mainly characterized in that: the rotation center of the sealing guide rail and the rotation center of the machine tool must be superposed to ensure the processing precision; however, the shape of the sealing guide rail of the bottle blowing machine is a quarter circle with a larger diameter, and the following two problems exist when the rotating center of the sealing guide rail is installed on the rotating center of the machine tool workbench in the process of clamping the sealing guide rail on the machine tool workbench: firstly, if the machine tool workbench is large enough, the sealing guide rail with the quarter circular arc is difficult to be superposed with the rotation center of the machine tool workbench and has large installation error, because the rotation centers of the sealing guide rail and the machine tool workbench are superposed, a mode of drawing a full circle of circular arc from the meter is required to be adopted, the swinging condition of the index of the meter is observed, the position of the sealing guide rail is adjusted until the rotation centers of the sealing guide rail and the machine tool workbench are superposed, the index of the meter is kept still, however, because the sealing guide rail only has the quarter circular arc, the meter can not be drawn in a full circle when the method is used, and the superposition of the rotation centers of the sealing guide rail and the machine tool workbench cannot; secondly, even if the rotation center of the sealing guide rail can be ensured to be coincident with the rotation center of the workbench within the required tolerance range, the overlarge arc radius of the sealing guide rail far exceeds the installation range of the workbench, as shown in fig. 1. Therefore, on the premise of ensuring the clamping precision of the sealing guide rail on the workbench, how to install the sealing guide rail in the machining range of the workbench is the key for realizing the four-axis linkage machining of the sealing guide rail.
