[0026] The present application is further described in detail below in conjunction with the accompanying drawings. It is necessary to point out here that the following specific implementation methods are only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application. Technical personnel in this field can make some non-essential improvements and adjustments to the present application based on the above application content.

[0027] Refer to the instruction manual Figures 1 to 5 A concentricity automatic compensation tool comprises a reference seat 2 installed on a machine tool 1, a support frame 3 is installed on the machine tool 1, a three-axis driving mechanism is installed on the support frame 3, a mounting frame 31 is installed on the output end of the three-axis driving mechanism, a mounting frame 4 is installed on the mounting frame 31, a processing tool 5 is installed on the mounting seat 4, a workpiece fixture 6 is installed on the machine tool 1, and the workpiece fixture 6 is located below the processing tool 5; a reference coordinate module 21 is installed inside the reference seat 2, and the coordinate point of the reference coordinate module 21 is a zero point; a side plate 51 is installed on the processing tool 5, a detection probe 52 is installed on the side plate 51, and the coordinate point between the processing tool 5 and the reference coordinate module 21 is calibrated by the detection probe 52; a compensation component is installed on the mounting seat 4, and the compensation component is used to drive the processing tool 5 to move.

[0028] It should be noted that the reference seat 2 is installed on the edge or outside of the machine tool 1, away from the processing position of the processing tool 5 on the machine tool 1. The coordinate point of the reference coordinate module 21 is an unchanging reference coordinate point. The processing tool 5 can find the center coordinate point of the machine tool 1 through the detection probe 52. After the processing is completed, the processing tool 5 will return to the center coordinate point according to the feeding program.

[0029] In this embodiment, the implementation scenario is specifically as follows: first, a reference coordinate module 21 with extremely high precision and stability is designed and manufactured. The reference coordinate module 21 has good rigidity and stability to prevent displacement during the processing. The reference coordinate module 21 is firmly fixed on the workbench of the machine tool 1 as a reference point for all subsequent operations to ensure that its position is stable and not easy to move, and is easy to access by the detection probe 52. A global coordinate system, i.e., the total coordinate, is established with the center of the reference coordinate module 21 as the origin. The relevant information of the total coordinate, i.e., the specific values ​​of the X, Y, and Z axes, is entered into the numerical control system as the reference total coordinate. The numerical control system is a CNC system with an adaptive control function, which can perform calculations and fine-tuning based on real-time feedback. The workpiece to be processed is mounted on the workpiece fixture 6, the position of the workpiece is preliminarily adjusted, and the workpiece is positioned using a traditional measuring tool or auxiliary equipment, which is the workpiece fixture 6, so that the center of the workpiece is close to the center of the reference coordinate module 21. A contact or non-contact detection probe 52 installed on the processing tool 5 is used to automatically detect the reference coordinate module 21 and the workpiece. The detection probe 52 first finds the center of the reference coordinate module 21, that is, the reference total coordinate, and then moves to the workpiece surface to determine the actual center position of the workpiece. The distance from the center of the reference coordinate module 21 to the center of the workpiece is calculated based on the data obtained by the detection probe 52, and the actual coordinates of the workpiece are adjusted accordingly. The newly determined actual coordinates of the workpiece center are automatically entered into the CNC system as the local coordinate system of this processing. If a deviation is found, the compensation component is used in conjunction with the automatic adjustment function of the CNC system to adjust the path or other parameters of the processing tool 5 to compensate for this deviation to ensure the accuracy of the final processing result. Before each centering or light cutting, the detection probe 52 or other precision measuring instruments are used to verify whether the concentricity and other key dimensions of the workpiece meet the requirements, and the relevant data of each processing is saved for quality tracing and technical improvement. The reference coordinate module 21 is used as an absolute reference point to ensure that all operations have a basis to rely on, so as to achieve the goal of quickly and accurately completing the centering task and reducing errors. It can effectively solve the data error of the processed parts caused by the eccentricity of the machine tool, improve the quality rate of workpieces, improve production efficiency and reduce labor costs.

[0030] Furthermore, the compensation component includes an X-axis compensation component 7 and a Y-axis compensation component 8. The X-axis compensation component 7 is arranged between the mounting seat 4 and the processing tool 5, and the X-axis compensation component 7 is used to drive the processing tool 5 to move along the X-axis direction. The Y-axis compensation component 8 is arranged between the mounting frame 31 and the mounting seat 4, and the Y-axis compensation component 8 is used to drive the processing tool 5 to move along the Y-axis direction.

[0031] It should be noted that the X-axis compensation component 7 drives the machining tool 5 to move along the X-axis direction for adjustment, and the Y-axis compensation component 8 drives the machining tool 5 to move along the Y-axis direction for adjustment.

[0032] Furthermore, the X-axis compensation assembly 7 and the Y-axis compensation assembly 8 both include a fixed base 71, on which a rotation driver 72 is mounted, and a positioning block 73 is mounted on one end of the fixed base 71 away from the rotation driver 72, and an external screw rod 74 is provided between the rotation driver 72 and the positioning block 73, and a movable block 75 is mounted on the external screw rod 74, and an internal screw block 76 is mounted inside the movable block 75, and the internal screw block 76 is threadedly connected to the external screw rod 74, and the rotation driver 72 drives the external screw rod 74 to rotate, and the movable block 75 is moved axially along the external screw rod 74 through the internal screw block 76.

[0033] It should be noted that the rotary driver 72 drives the outer screw 74 to rotate, the positioning block 73 is used to support the outer screw 74, the inner screw block 76 is fixed inside the movable block 75, and the rotation of the outer screw 74 drives the movable block 75 to move through the inner screw block 76.

[0034] Furthermore, a compensation chamber 41 is provided inside the mounting seat 4, the X-axis compensation assembly 7 is installed inside the compensation chamber 41, and the machining tool 5 is detachably connected to the movable block 75 of the X-axis compensation assembly 7.

[0035] It should be noted that the movable block 75 of the X-axis compensation assembly 7 is fixed to the machining tool 5 and is used to drive the machining tool 5 to move along the X-axis direction.

[0036] Furthermore, a connecting block 42 is fixedly provided at one end of the mounting seat 4, and the connecting block 42 passes through the interior of the mounting frame 31, the Y-axis compensation assembly 8 is installed on the mounting frame 31, and the movable block 75 of the Y-axis compensation assembly 8 is connected to the connecting block 42.

[0038] Furthermore, guide grooves 78 are provided on both sides of the fixed seat 71 , and a guide block 77 is fixedly provided at one end of the movable block 75 corresponding to the fixed seat 71 , and the guide block 77 is arranged in an L shape, and one end of the guide block 77 is slidably arranged inside the guide groove 78 .

[0039] It should be noted that the guide groove 78 is provided along the axial direction of the outer screw rod 74 to guide the movement of the movable block 75 .

[0040] Furthermore, the three-axis driving mechanism includes an X-axis driver 11 , a Y-axis driver 12 and a Z-axis driver 13 , the X-axis driver 11 is mounted on the machine tool 1 , the Y-axis driver 12 is mounted on the support frame 3 , and the Z-axis driver 13 is mounted on the mounting frame 31 .

[0041] It should be noted that the X-axis driver 11 drives the support frame 3 to move along the X-axis, the Y-axis driver 12 drives the Z-axis driver 13 and the mounting frame 31 to move along the Y-axis, and the Z-axis driver 13 drives the mounting frame 31 and the machining tool 5 to move along the Z-axis.

[0042] In this embodiment, the implementation scenario is specifically as follows: For ease of understanding, the following is an explanation of compensation for errors generated on the X and Y axes. The workpiece is assembled on the workpiece fixture 6. When processing the first workpiece, the processing tool 5 first finds the original center coordinate point of the machine tool 1 through the detection probe 52, and compares the first coordinate with the original coordinate of the reference coordinate module 21, and records the original center coordinate point of the processing tool 5 as the first coordinate. The machine tool 1 as a whole has a concentricity error due to temperature drop and thermal expansion and contraction. This phenomenon causes the processing tool 5 to deviate from the first coordinate, that is, the actual coordinate of the processing tool 5 is recorded as the second coordinate. By comparing the second coordinate with the original coordinate of the reference coordinate module 21, the correction error is obtained. The deviation coordinate value of the tool 5, when the deviation coordinate value is -n, -m, the coordinate value is compensated to +n, +m by the X-axis compensation component 7 and the Y-axis compensation component 8, that is, the obtained deviation coordinate value is reversely compensated by the X-axis compensation component 7 and the Y-axis compensation component 8 with the same value. The overall compensation is performed by allowing the machine tool to automatically center the reference coordinate module 21 for compensation, and the machine tool automatically enters the coordinates to achieve the goal of concentricity. Before each light or light knife, the detection probe 52 is used to center the reference coordinate module 21 and automatically enter the total coordinates. The eccentricity caused by various factors is re-aligned and corrected through compensation by the X-axis compensation component 7 and the Y-axis compensation component 8, so as to obtain more accurate concentricity.

[0043] Refer to the instruction manual Figure 4 , Figure 6 and Figure 7 A blowing seat 22 is installed inside the reference seat 2, and the blowing seat 22 is located below the reference coordinate module 21. The outside of the blowing seat 22 is connected to a nozzle 23, and several groups of nozzles 23 are arranged around the outside of the reference coordinate module 21.

[0044] It should be noted that the reference coordinate module 21 is cleaned by blowing air through the nozzle 23 to ensure that the reference coordinate module 21 is clean and tidy.

[0045] Furthermore, a processing block 221 is installed in the middle of the blowing seat 22 , an air outlet chamber 225 is provided above the processing block 221 , and an air inlet chamber 226 is provided below the processing block 221 .

[0046] It should be noted that cold air is provided to the inside of the blowing seat 22 through the air inlet chamber 226 , and the cold air passes through the processing block 221 into the air outlet chamber 225 , and is finally blown out through the nozzle 23 .

[0047] Furthermore, a cooling pipe 222 is installed inside the processing block 221 , a dispersion mesh plate 223 is provided above the cooling pipe 222 , and an elastic filling body 224 is filled in the middle of the dispersion mesh plate 223 .

[0048] It should be noted that the cooling pipe 222 is connected to an external water pipe, and the elastic filling body 224 includes a plurality of elastic balls with different diameters.

[0049] In this embodiment, the implementation scenario is specifically as follows: in order to ensure the coordinate reference of the reference coordinate module 21, the reference coordinate module 21 is cleaned by blowing air through an air blowing seat 22 and a nozzle 23. The nozzles 23 are arranged opposite to each other around the outer periphery of the reference coordinate module 21. Cold air is input into the blowing seat 22 through the air inlet chamber 226, and is blown to the reference coordinate module 21 through the nozzle 23. In order to reduce the influence of high temperature on the reference coordinate module 21, it is necessary to ensure the temperature of the blown cold air. Therefore, a circulating cooling pipe 222 is installed inside the processing block 221, and cold water is passed into the cooling pipe 222 to reduce the temperature inside the blowing seat 22, thereby ensuring that the cold air is transported at a low temperature in the blowing seat 22. Due to the concentration of the cold air flow Entering from the air inlet chamber 226, the air flow enters different nozzles 23 at different speeds. When the blowing speed of a nozzle 23 is too fast, the blowing speed balance between the two relative nozzles 23 will be destroyed, causing the reference coordinate module 21 to shake toward the slow nozzle 23, affecting the reference effect of the reference coordinate module 21. Therefore, by filling the inside of the dispersion mesh plate 223 with elastic filling bodies 224, when high-speed gas blows through, the air flow is dispersed by a number of elastic filling bodies 224, so that the air flow entering the inside of the air outlet chamber 225 is evenly dispersed, thereby reducing the difference in blowing speeds between the multiple nozzles 23, making the blowing speeds of the multiple nozzles 23 relatively uniform, and avoiding the reference coordinate module 21 from shaking and affecting the reference effect.

[0050] Refer to the instruction manual Figure 8 The present invention also provides an application method of the concentricity automatic compensation tool, comprising the following steps: S1: Design and install a high-precision reference module, which is fixed on the workbench of the machine tool and its coordinates serve as the reference coordinate point for all subsequent operations; S2: Establish a total coordinate system, establish a total coordinate system with the center of the reference module as the origin, and enter the specific values ​​of the total coordinate system into the CNC system as the reference total coordinate; S3: Clamp the workpiece, place the workpiece to be processed on the workbench, and position the workpiece so that the center of the workpiece is close to the center of the reference module; S4: Probe detection: the probe first finds the reference total coordinates of the reference module, then moves to the workpiece and determines the actual center coordinates of the workpiece.

[0051] The above embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the present invention.
