A processing technology of four-axis linkage processing sealing guide rail of bottle blowing machine

Abstract

A four-axis linkage processing process for sealing guide rails of blow molding machines. Through the above steps, the positional relationship between the rotation center of the worktable of the four-axis machine tool and the position relationship between the sealing guide rails can be associated with the programming software, ensuring that the sealing guide rails are on the workbench. Under the premise of the above clamping accuracy, install the sealing guide rail within the processing range of the workbench to realize the overall processing of the sealing guide rail and avoid segmental processing, so as to ensure the processing accuracy of the sealing guide rail and effectively avoid the movement of the rolling bearing on the surface of the sealing guide rail Deviation of the trajectory and avoiding loud noise, avoiding faster wear of the sealing guide rail, and prolonging the service life of the sealing guide rail.

Description

technical field [0001] The invention relates to a processing technology for four-axis linkage processing a sealing guide rail of a bottle blowing machine. Background technique [0002] As the core part of the bottle blowing machine, the main processing technology currently used for the sealing guide rail is to process the guide rail surface in sections at the swing angle of the horizontal machining center. The trajectory of the bearing on the surface of the guide rail is deviated, and at the junction of the segmental processing, there are contact marks due to processing errors, so that the roller bearing will generate large noise and wear when running at high speed on the sealed guide rail processed by this process. Also very fast. [0003] In order to solve the above problems, it is necessary that the machining trajectory of the tool of the machine tool on the surface of the sealing guideway is consistent with the movement trajectory of the roller bearing on the surface of...

Problems solved by technology

However, the key point of the four-axis linkage processing of the sealing guide rail is that the rotation center of the sealing guide rail and the rotation center of the machine tool must coincide to ensure the processing accuracy; but the shape of the sealing guide rail of the blow molding machine is a quarter of the larger diameter. Circle, in the process of clamping it on the machine tool table, there are two problems in installing the rotation center of the sealing guide rail to the rotation center of the machine tool table: First, if the machine tool table is large enough, It is very difficult to align the quarter-arc sealing guide rail with the rotation center of the machine tool table, and the installation error is large, because to make the two rotation centers coincide, it is necessary to use the comparison table to make a full circle arc and observe the swing of the index of the table, adjust the position of the sealing guide rail until the center of rotation of the two coincides, and the index of the table remains unchanged. However, since the sealing guide rail only has a quarter of the arc, when using In the above method, it is impossible to play the meter in a full circle, so it is impossible to achieve the coincidence of the rotation centers of the two; second, even if the rotation center of the sealing guide rail and the rotation center of the worktable can be guaranteed to coincide within the required tolerance range, but the sealing guide rail is too large. The arc radius far exceeds the installation range of the workbench, such as figure 1 shown
