Abstract
The invention relates to the technical field of machining and discloses a method for machining a through keyway of a long shaft by utilizing a planer. The method comprises the following steps: selecting the suitable planer, clamping both ends of a long shaft workpiece to be machined by two fixtures, determining a clamping height of the long shaft workpiece to be machined, placing a plurality of supporting blocks below the long shaft workpiece to be machined and firmly fixing the long shaft workpiece to be machined; selecting and installing a tool with a suitable specification; firstly, carrying out rough planing machining, then replacing the tool with a forming tool to carry out forming machining on the through keyway, and finally, carrying out precise planing operation to obtain the through keyway with a regular size. According to the method disclosed by the invention, straightness and the degree of symmetry of the through keyway and firmness of clamping are convenient to ensure; the phenomenon of tool vibration in the planing process can be eliminated and machining equipment is improved; roughness of the machined face the through keyway can be effectively ensured so as to accord with the requirement on machining accuracy; the clamping times of the workpiece are small, the machining accuracy is high, production efficiency is effectively improved and production cost is reduced.
Description
Technical field
The present invention relates to Machining Technology field, specifically a kind of method utilizing planer processing major axis to lead to keyway.
Background technology
In mechanical processing process, generally the processing of keyway is carried out on the lathes such as milling machine, slotting machine, broaching machine, the processing of most of machine components keyway can be met.On major axis length being greater than to 1.5 meters during the logical keyway of processing, above lathe cannot ensure for the symmetry of logical keyway, linearity, tolerance equidimension, machining must the precision of logical keyway inadequate, workpiece quality can not meet the demands, workpiece can be made time serious to scrap, cause the waste of material.
Summary of the invention
The object of this invention is to provide a kind of method utilizing planer processing major axis to lead to keyway, to improve machining accuracy, guarantee crudy, the reduction production cost that major axis leads to keyway.
For solving the problems of the technologies described above, the technical solution used in the present invention is:
Utilize planer processing major axis to lead to a method for keyway, it comprises the following steps:
The planer that step one, the long axis workpiece length to be processed of leading to keyway according to major axis select stroke suitable, with two fixtures, long axis workpiece to be processed is installed, linearity, pretightning force between adjustment fixture, with the two ends of holder long axis workpiece to be processed, determine that long axis workpiece to be processed is installed highly, several back-up block is placed, by fixed for long axis workpiece to be processed in the below of long axis workpiece to be processed;
Step 2, size according to logical keyway to be processed, select, install the cutter of suitable specification;
The processing of step 3, logical keyway: first carry out force plane processing, then changes molding cutter and carries out processing and forming to logical keyway, finally carry out accurate planning operation, obtain the logical keyway of given size.
As a further improvement on the present invention, the back-up block placed below long axis workpiece to be processed in described step one is at least 1.
In the invention process process, need detect in real time each step, meet the requirements prescribed with the machining accuracy and quality that ensure workpiece.
Have the following advantages compared with the processing method that the present invention and prior art major axis lead to keyway:
1, the present invention adopts two two ends of fixture to workpiece to be processed to be installed, the strong degree be convenient to ensure the linearity of logical keyway, symmetry and be installed; Place back-up block in the below of long axis workpiece to be processed, the cutter phenomenon of quivering during planing operation can be eliminated, improve crudy;
2, first carry out force plane processing in step 3 of the present invention, then change molding cutter and processing and forming is carried out to logical keyway, finally carry out accurate planning operation, effectively can ensure the roughness of logical keyway machined surface, to meet the requirement of machining accuracy;
3, the method workpiece of the present invention number of times that is installed is few, and machining accuracy is high, and effect improves production efficiency, reduces production cost.

Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is further detailed explanation.
As shown in Figure 1, a kind of method utilizing planer processing major axis to lead to keyway, it comprises the following steps:
The planer that step one, the length of leading to the long axis workpiece to be processed 1 of keyway according to major axis select stroke suitable, with two fixtures 2, long axis workpiece 1 to be processed is installed, linearity, pretightning force between adjustment fixture 2, the two ends of long axis workpiece 1 to be processed are clamped with fixture 2, determine the height that is installed of long axis workpiece 1 to be processed, 1 back-up block 3 is placed, by fixed for long axis workpiece 1 to be processed in the below of long axis workpiece 1 to be processed;
Step 2, size according to logical keyway to be processed, select, install the cutter 5 of suitable specification;
The processing of step 3, logical keyway: first carry out force plane processing, then changes molding cutter and carries out processing and forming to logical keyway, finally carry out accurate planning operation, obtain the logical keyway of given size.
In process, Real-Time Monitoring is carried out to each step, to ensure machining accuracy and crudy.
The placement quantity of back-up block 3, according to the length of major axis workpiece 1 to be added and add the vibration situation in man-hour and adjust in time, to prevent cutter phenomenon of quivering.
