What causes the layout of engraving machine to change
If it is found that the layout of the engraving machine has changed, it may be caused by many reasons.
Therefore, it is best for everyone to find out what causes affect the layout of the engraving machine before adopting corresponding methods to solve it.
The following is a specific analysis of this phenomenon by Xiao Bian. You can refer to it.
On the basis of meeting the basic requirements of the overall layout, the basic factors affecting the layout of engraving machines should also be considered: 1. The influence of surface formation movement the processing surfaces with different shapes often use different cutting tools to process, therefore, the form and number of surface movements are different and lead to differences in layout.
The same shape of the processing surface, due to the technical requirements and productivity requirements of the workpiece and other different, can also use different tools, different surface formation movement to process, so as to form a different layout.
From this, it can be seen that the movement formed on the surface of the workpiece directly determines the layout of the engraving machine and is the decisive factor affecting the layout of the engraving machine.
Therefore, in the layout engraving machine, must according to the processing requirements, comprehensive, comprehensive consideration of the workpiece surface formation method and movement, in order to make a better technical and economic effect of the layout design.
2, engraving machine motion distribution of the impact of the workpiece surface formation method and movement of the same, and the engraving machine motion distribution is different, the layout of the engraving machine will be different.
For the layout of the same kind of motion distribution, due to the different arrangement of the guide rail and other structural forms, the layout of the engraving machine will also change.
In the distribution of engraving machine movement, generally should pay attention to the following points: 1)The weight of moving parts should be as light as possible.
Under the same other conditions, the smaller the weight of the moving parts, the smaller the required motor power and the size of the transmission parts. 2)
Should be conducive to improving machining accuracy 3)
It should be conducive to improving the rigidity of engraving machine and reducing the floor area 4)
The influence of the size, weight and shape of the workpiece the surface formation movement of the workpiece and the motion distribution of the engraving machine parts are basically the same, while the size, weight and shape of the workpiece are different, and the layout of the engraving machine will also be very different.
In addition, the influence of engraving machine performance requirements should also be considered, such as vibration, noise, thermal deformation, stiffness and vibration resistance, the influence of convenient operation, the influence of modular design method, etc.
Through consulting relevant literature, the basic layout of engraving machine usually has two schemes as shown in the following figure: both layouts adopt gantry frame structure, and the rigidity of engraving machine is high. Layout (1)
In the scheme, the Workbench is fixed, the carving head moves horizontally and up and down, and the column moves vertically.
This scheme is convenient to deform engraving machines with different longitudinal lengths.
Because the Workbench does not move, the bearing capacity is good, and it is suitable for processing heavy workpieces.
When using the extended bracket to support the longitudinal long workpiece for batch processing, the fulcrum height is the same, so the bracket support is convenient to adjust.
However, it is difficult to guarantee the movement precision of the carving head and the movement of the upright post is heavy. Layout (2)
In the scheme, the upright post is fixed, the carving head moves horizontally and up and down, and the Workbench moves vertically. Due to the movement of the workbench, the carrying capacity is relatively large (1)The plan is poor.
If the workpiece carried by the design is lighter, the motor power and the size of the transmission parts required by this layout mode are smaller and the movement is lighter.
When using the extended bracket to support the longitudinal long workpiece for batch processing, the fulcrum height is the same, so the bracket support is convenient to adjust, but the bracket structure is relatively laid out (1)The scheme is slightly complicated.
The biggest advantage of this scheme is that the motion accuracy of the carving head is easier to ensure.
After the above comparison, fully considering the basic requirements of the layout, the basic factors affecting the layout and the design parameters of the three-coordinate CNC engraving machine, the layout (2)The plan.
Generally, these factors affect the layout of the engraving machine. If you don't know the specific reason after reading this article, Xiaobian can't do anything about it.
