Example 1
In accordance with an embodiment of the present invention, there is provided an embodiment of a method for processing axis elongation, it being noted that the steps illustrated in the flowchart of the drawings may be performed in a computer system such as a set of computer-executable instructions and that, although a logical order is illustrated in the flowchart, in some cases the steps illustrated or described may be performed in an order different than that illustrated herein.
Fig. 1 is a flow chart of a method of processing shaft elongation according to an embodiment of the present invention. As shown in fig. 1, the method may include the steps of:
step S102, the elongation of the main shaft is obtained.
In the technical solution provided by step S102 of the present invention, when the spindle is subjected to thermal deformation, the end of the spindle may be elongated, so that the elongation of the end of the spindle may be obtained.
And step S104, determining a target compensation value corresponding to the elongation, and compensating the numerical control system where the main shaft is located based on the target compensation value, wherein the numerical control system after compensation keeps the control of the main shaft before elongation and the main shaft after elongation unchanged.

Through the steps S102 and S104, the elongation of the main shaft is obtained; the method includes the steps of determining a target compensation value corresponding to the elongation, and compensating a numerical control system where the spindle is located based on the target compensation value, wherein the numerical control system after compensation keeps unchanged in control over the spindle before elongation and the spindle after elongation, that is, the embodiment determines the target compensation value corresponding to the elongation through the obtained elongation of the spindle after elongation, and then compensates the numerical control system where the spindle is located based on the obtained target compensation value, so that the purpose that the numerical control system performs real-time compensation on the numerical control system is achieved, the technical problem that the numerical control system is low in machining precision is solved, and the technical effect of improving the machining precision of the numerical control system is achieved.
The above-described method of this embodiment is further described below.
As an optional implementation manner, in step S104, compensating the numerical control system where the spindle is located based on the target compensation value includes: and controlling the main shaft to move the target compensation value in the direction opposite to the elongation.
In this embodiment, after obtaining the target compensation value, the numerical control system may be controlled to obtain a target value corresponding to the elongation of the end of the main shaft, and then the entire main shaft is controlled to move in the direction opposite to the elongation according to the value of the target value, where the value of the moving distance is the value of the target value, that is, the target compensation value.
For example, when the numerical control system indicates that the end of the spindle is extended downward by 2 units during the machining of the spindle, the numerical control system controls the Z-axis of the machine tool to move upward by 2 units, which corresponds to the position of the end of the spindle when the end of the spindle is not extended. Optionally, since the spindle is disposed on the Z axis of the machine tool and the target tool is disposed on the spindle, the tool tip of the target tool can be controlled to remain at the original position, so that the precision of the machine tool in processing a product can be ensured, and the target object can be accurately processed by the target tool.
As an alternative embodiment, determining a target compensation value corresponding to the elongation includes: acquiring a compensation coefficient and a zero offset, wherein the compensation coefficient and the zero offset are used for determining a target compensation value; a plurality of compensation values corresponding to the elongation are determined based on the compensation coefficient and the zero offset, and a target compensation value is determined among the plurality of compensation values.
In this embodiment, after the elongation amount of the main shaft elongation is obtained, a compensation coefficient and a zero offset for determining a target compensation value may be obtained, and then a plurality of compensation values corresponding to the elongation amount of the main shaft elongation are calculated through the compensation coefficient and the zero offset, so that an optimal compensation value may be selected from the plurality of obtained compensation values through a plurality of tests, and the optimal compensation value is determined as the target compensation value, thereby realizing compensation of the numerical control system through the target compensation value.
Alternatively, the compensation coefficients and zero offset in this embodiment may be used to control different spindle thermal compensation effects.

As an optional implementation, obtaining the zero offset includes: under the condition of compensating a numerical control system where a main shaft is located, measuring the tail end of the main shaft by a tool setting gauge based on the numerical control system to obtain a first measurement result; under the condition that the numerical control system where the main shaft is located is not compensated, measuring the tail end of the main shaft based on the tool setting gauge to obtain a second measurement result; comparing the first measurement result with the second measurement result to obtain a comparison result; based on the comparison results, a zero offset is determined.
In this embodiment, when the numerical control system where the spindle is located is compensated, the coordinate of the tool nose of the tool disposed at the end of the spindle is measured by the tool setting gauge of the numerical control system to obtain a first measurement result, and then, by using the same method, when the numerical control system where the spindle is located is not compensated, the coordinate of the tool nose of the tool disposed at the end of the spindle is measured by the tool setting gauge of the numerical control system to obtain a second measurement result, and after the first measurement result and the second measurement result are obtained, the two measurement results are compared, so that a zero offset (zero offset) of the spindle can be obtained, thereby realizing that the thermal compensation amount of the numerical control system is zero when the machine tool where the spindle is located is static.
Alternatively, in this embodiment, the coordinates of the tool nose of the tool disposed at the end of the spindle may be measured by the tool setting gauge of the numerical control system under the conditions that the spindle rotates at 3 kilo revolutions per minute, the tool setting time is 30 seconds at intervals, and the tool setting is accumulated for 1 hour, so as to obtain the measurement result.
As an alternative embodiment, acquiring the elongation of the main shaft elongation comprises: acquiring a target distance between the tail end of the main shaft and a displacement sensor, wherein the displacement sensor is arranged on the tail end of the main shaft and is used for converting the target distance into first voltage data; an amount of elongation corresponding to the first voltage data is determined.
In this embodiment, a displacement sensor may be installed inside or outside the spindle tip, so that a target distance between the spindle tip and the displacement sensor may be acquired by the displacement sensor, the acquired target distance may be converted into voltage data (analog quantity of voltage) by the displacement sensor, and after the voltage data is acquired, an elongation corresponding to the voltage data may be determined.
In the above embodiment, after the first voltage data is obtained, the analog quantity acquisition module may be used to acquire the obtained first voltage data, and transmit the voltage data to the numerical control system. The numerical control system is provided with an analog quantity interface which can read the voltage value of the accessed electricity between 0V and 10V, so that after the numerical control system reads the first voltage data, the read voltage value can be transmitted into a parameter of #1000 every 10 milliseconds, and then the elongation corresponding to the voltage value is determined according to the voltage value reflected by the parameter.
Alternatively, the first voltage data in this embodiment may be 0-10V.
As an alternative embodiment, determining the elongation corresponding to the first voltage data includes: the elongation corresponding to the first voltage data is determined based on a linear relationship between the first voltage data and the elongation.
In this embodiment, after the distance between the end of the spindle and the displacement sensor is converted into the first voltage data, since the first voltage data and the elongation of the spindle are in a linear relationship, that is, the value of the first voltage data reflects the elongation of the spindle, the elongation corresponding to the first voltage data can be determined based on the linear relationship between the first voltage data and the elongation.
As an alternative embodiment, converting the target distance into first voltage data, and determining the elongation based on the first voltage data, includes: filtering the first voltage data to obtain second voltage data; an elongation corresponding to the second voltage data is determined.
In this embodiment, when the numerical control system receives the voltage data transmitted by the analog quantity acquisition module, the received voltage signal may include a plurality of interference signals due to various interferences, so that data transmitted in the #1000 parameter of the numerical control system fluctuates up and down, and therefore, the received voltage signal may be processed by using a programmable logic control filter (PLC filter), so that the processed voltage data may be obtained, and then the elongation corresponding to the processed voltage data is determined according to the processed voltage data, so that the obtained elongation of the spindle is more stable and accurate.

In this embodiment, the numerical control system processes the first voltage data by using PLC filtering, that is, the numerical control system may average every 20 values of the value in the #1000 parameter to the #1001 parameter, and the value in the #1001 parameter is voltage data (voltage value) corresponding to the elongation of the spindle, which is obtained by the numerical control system, so that the voltage data may be determined as the second voltage data, and no interference signal exists in the obtained second voltage data.
In the related art, in order to reduce the influence of the thermal deformation of the shaft of the numerical control system on the machining precision of the machine tool of the high-precision numerical control system, the main shaft of the machine tool is moved to a constant-temperature and constant-humidity workshop, or the main shaft of the machine tool is cooled by a water cooling machine, so that the machining precision of the numerical control system is improved.
