Embodiment Construction

[0028] see figure 2 , Figure 4, Figure 5, Figure 6 and Figure 7. The low-speed diesel engine frame guide plate receiving knife processing method of the present invention is characterized in that the method adopts a dragon milling CNC machine tool and processes according to the following steps:

[0029] ① Put the frame 1 into place, and install the guide plate attachment 5 at the lower end of the ram 4 of the dragon milling machine, such as figure 2 As shown, the beam 3 and the ram 4 of the dragon milling machine drive the guide plate attachment 5 and its cutter head 6 to complete the rough machining and semi-finishing of the lower half of the frame 1 guide plate surface 2 from top to bottom;

[0030] ②During finishing machining, the cutter head 6 of the guide plate attachment 5 processes the guide plate to the middle position from top to bottom. When the stroke of the ram 4 is 400mm, the beam 3 and the ram 4 drive the guide plate attachment 5 and its cutter head 6 to gradua...

Abstract

The low-speed diesel engine frame guide plate cutter-receiving machining method utilizes planar-type miller numerically-controlled machine tool and adopts the following steps: (1). inverting machine frame, using ram of planar-type miller to drive cutterhead of guide plate attachment to implement rough machining and semi-finishing of lower half-portion of said guide plate surface from top to bottom; (2). when finishing, using said cutterhead to finish the guide plate to middle part, and when the stroke of the ram yet has Lmm, the ram progressively outward diclines to compensate hmm; (3) restoring the machine frame to normal state; (4) the ram drive guide plate attachment to complete rest rough machine and semi-finishing from top to bottom.

Description

[0001] New technology field: [0002] The invention relates to a low-speed diesel engine, in particular to a tool-connecting processing method for a frame guide plate of a low-speed diesel engine. Background technique: [0003] For most low-speed diesel engine frames, the entire guide bar can be machined in one feed. Such as figure 1 , when the frame is placed upright (the last station of the dragon milling process), the machine tool is equipped with a guide plate attachment, the beam (W axis) and the ram (Z axis) move at the same time, and the guide plate surface is processed from top to bottom. [0004] In the following cases: 1) The height of the frame is limited by the machine tool; 2) The length of the guide plate surface exceeds the maximum processing range of the attachment; 3) The width of the ram exceeds the opening of the guide plate surface. The entire guide plate cannot be processed at one time, and the machine frame needs to be turned over to pick up the knife t...
