Description

A Method for Realizing Tool Change and XY Axis Synchronous Movement of Drilling and Tapping Machine

technical field

The invention relates to the field of numerically controlled drilling and tapping machine tools, in particular to a method for realizing the simultaneous movement of the tool change and the XY axes of the drilling and tapping machine.

Background technique

CNC drilling and tapping machine tools, that is, drilling and tapping machines, are equipment used for drilling, tapping, slotting and milling of metal materials. In the processing of various metal products, the processing efficiency of drilling and tapping machines requirements are generally higher.

In the operation of the drilling and tapping machine, it is often necessary to change the tool. Among them, the tool changing action of the drilling and tapping machine generally includes the following steps:

1. Lift the Z axis to move the tool to a safe point;

2. The cutter head rotates to change the tool;

3. The Z axis descends to complete the tool change action;

4. Carry out XY axis movement and continue processing.

In the above-mentioned tool change action, on the one hand, the overall action of the above-mentioned tool change and subsequent processing is not smooth enough, and the look and feel is poor; on the other hand, the above-mentioned tool change action takes a long time, thus affecting the machining efficiency of the drilling and tapping machine .

Contents of the invention

In order to solve the above problems, the present invention provides a method for realizing the simultaneous movement of the tool change and the XY axis of the drilling and tapping machine.

According to one aspect of the present invention, there is provided a method for realizing the simultaneous movement of the tool change and the XY axis of the drilling and tapping machine, including the following steps:

In some embodiments, in step 2), it is modified to Pr3215=2. Its benefit lies in that it describes the method of modifying the call mode parameters when selecting tools.

In some implementations, in the macro mode of step 2), X and Y parameters can be brought in. It is beneficial in that it describes functionality in macro mode.

In the present invention, a method for synchronizing the tool change of the drilling and tapping machine with the XY axis, by optimizing the action of the drilling and tapping machine when the tool is changed to the T code, the tool changing action is synchronized with the XY axis, which not only ensures that the drilling and tapping machine The smoothness and good look and feel of the tool change action also improves the speed of the tool change action and the processing efficiency of the drilling and tapping machine.

Detailed ways

The present invention will be described in further detail below.

In this method, the core pre-processor is used to process the controller, so that the logic is: during the operation of the processing program, when a T code command is encountered, unless a single block containing X and Y coordinates is collected, the processing program will be processed. Merged into the same line of processing, thus realizing the simultaneous movement of tool change and XY axis.

The process of the method mainly includes several steps, which are respectively described as follows.

The first step is to modify the tool change macro program in the controller.

The tool change macro program is T0000. When modifying it, it is necessary to add an argument to the single block that moves the Z axis in the tool change macro program T0000 to a safe point.

Table 1 Parameters and their corresponding variables

argument Corresponding variable argument Corresponding variable argument Corresponding variable A #1 J #5 T #20 B #2 K #6 u #twenty one C #3 L #12 V #twenty two D. #7 m #13 W #twenty three E. #8 P #16 x #twenty four f #9 Q #17 Y #25 h #11 R #18 Z #26 I #4 S #19 X1 GETARG(X1)

Wherein, the added arguments are X and Y and their respective corresponding variables. Each argument and its corresponding variables are shown in Table 1.

It can be known from Table 1 that the variable corresponding to X is #24, and the variable corresponding to Y is #25. Therefore, the parameter added in the single section of moving the Z axis to the safe point in the tool change macro program T0000 is X#24 and Y#25. For example, a statement after adding arguments is as follows:

G91 G01 Z(#103-#102)X#24Y#25F#106.

The second step is to modify the call mode parameter when selecting a tool in the controller parameters.

The modified call mode parameter for tool selection is Pr3215, the range of this parameter is 0~2, the initial value is 0, and it is valid after restarting the machine after modification.

The parameter Pr3215 is used to set the call logic of T Code, and the meaning of each value is as follows.

Pr3215＝0: As a T code auxiliary code, it means not to call T0000;

Pr3215=1: means calling T0000 through the subroutine, and does not read and occupy any arguments, for example, when Pr3215=1, the program content is:

T01 M03 S1000

Then the effect is: the machine will perform tool change, and then execute the spindle forward rotation;

Pr3215＝2: Indicates calling T0000 through the macro program, and the occupied parameter can be read. For example, when Pr3215=2, the program content is:

T01 M03 S1000

Then the effect is: if there are corresponding variables (such as #13 and #19) used in T0000, the corresponding reference codes (that is, M code and S code) will be invalid, and the machine will only perform tool change.

In this step, modify Pr3215 to 2 to make it a macro mode, and in this mode, X and Y parameters can be brought in.

The third step is to import the modified data and other data into the controller,

Finally, after processing, the tool change and the XY axis can be moved simultaneously.

Specifically, after the above modification, the tool change action of the drilling machine will be modified to the following steps:

1. Lift the Z axis to move the tool to a safe point, and at the same time move the XY axis;

2. Then the cutterhead rotates to change the cutter;

3. The Z-axis descends to complete the tool change action, and the XY-axis moves at the same time.

To sum up, in the present invention, a method for realizing the simultaneous movement of the tool change of the drilling and tapping machine and the XY axis is to optimize the action of the drilling and tapping machine when performing the T code tool change, and to synchronize the tool changing action with the XY axis, not only It ensures the smoothness and good look and feel of the tool change action of the drilling and tapping machine, and also improves the speed of the tool changing action and the processing efficiency of the drilling and tapping machine.

What have been described above are only some embodiments of the present invention. For those skilled in the art, without departing from the inventive concept of the present invention, several modifications and improvements can be made, and these all belong to the protection scope of the present invention.
