Description

Technical Field

[0001] This invention relates to the field of machine tool technology, and more specifically, to an automatic concentricity compensation tool and its application method. Background Technology

[0002] Due to the significant temperature differences in machine tool materials, cooling systems, and production environments, errors in position and concentricity caused by thermal expansion and deformation of machine tools have remained unresolved since the development of machine tools. As machine tool precision requirements increase and the precision of workpieces produced by customers becomes higher, some customers refuse to accept improvements in concentricity errors caused by thermal expansion and contraction due to factors such as the high cost of air-conditioned or temperature-controlled workshops, high electricity costs for air conditioning, and low unit prices of workpieces. Therefore, most workpiece concentricity problems can be solved through automatic compensation of such errors using tools.

[0003] Currently, after the workpiece is processed, the workpiece eccentricity value needs to be detected by a three-dimensional measuring machine, and then the eccentricity value needs to be compensated back by a grinding machine. The disadvantages are that it increases the processing cost and manufacturing time. Before finishing, it is necessary to manually re-center the workpiece and then finish it. It cannot be automated, the labor cost is high, or the workpiece is scrapped, or the finishing time is long. Eccentricity still exists even when multiple tools are used for processing. Machine tool eccentricity causes data errors in the processed parts, which affects the workpiece yield and production efficiency. Summary of the Invention

Detailed Implementation

[0033] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0034] Refer to the instruction manual appendix Figures 1 to 5 An automatic concentricity compensation tool includes a reference base 2 mounted on a machine tool 1, a support frame 3 mounted on the machine tool 1, a three-axis drive mechanism mounted on the support frame 3, a mounting bracket 31 mounted on the output end of the three-axis drive mechanism, a mounting seat 4 mounted on the mounting bracket 31, a machining tool 5 mounted on the mounting seat 4, and a workpiece fixture 6 mounted on the machine tool 1, with the workpiece fixture 6 located below the machining tool 5. A reference coordinate module 21 is installed inside the reference base 2, and the coordinate point of the reference coordinate module 21 is the zero point. A side plate 51 is mounted on the machining tool 5, and a detection probe 52 is mounted on the side plate 51. The coordinate point between the machining tool 5 and the reference coordinate module 21 is calibrated through the detection probe 52. A compensation component is mounted on the mounting seat 4, and the compensation component is used to drive the machining tool 5 to move.

[0035] It should be noted that the reference base 2 is installed on the edge or outside of the machine tool 1, away from the machining point of the machining tool 5 on the machine tool 1. The coordinate point of the reference coordinate module 21 is a constant reference coordinate point. The machining tool 5 can find the center coordinate point of the machine tool 1 through the detection probe 52. After the machining is completed, the machining tool 5 will return to the center coordinate point according to the feed program.

[0036] In this embodiment, the specific implementation scenario is 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 processing. The reference coordinate module 21 is firmly fixed on the worktable of the machine tool 1 as a reference point for all subsequent operations, ensuring its position is stable and not easily moved, and 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 CNC system as the reference total coordinate. The CNC system is a CNC system with adaptive control function, which can perform calculations and fine adjustments based on real-time feedback. The workpiece to be processed is installed on the workpiece fixture 6, and the position of the workpiece is initially adjusted. The workpiece is positioned using a traditional measuring tool or auxiliary device, which is the workpiece fixture 6, so that the center of the workpiece is close to the center of the reference coordinate module 21. The 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 locates the center of the reference coordinate module 21, i.e., the reference total coordinate, and then moves to the workpiece surface to determine the actual center position of the workpiece. Based on the data obtained by the detection probe 52, the distance from the center of the reference coordinate module 21 to the center of the workpiece is calculated, and the actual coordinate of the workpiece is adjusted accordingly. The newly determined actual coordinate of the workpiece center is automatically entered into the CNC system as the local coordinate system for this machining. If a deviation is found, the path or other parameters of the machining tool 5 are adjusted by the compensation component in conjunction with the automatic adjustment function of the CNC system to compensate for the deviation, ensuring the accuracy of the final machining result. Before each centering or finishing cut, the concentricity and other key dimensions of the workpiece are verified by the detection probe 52 or other precision measuring instruments. The relevant data of each machining is saved for quality traceability and technical improvement. The reference coordinate module 21 serves as an absolute reference point to ensure that all operations are based on data, achieving the goal of quickly and accurately completing the centering task and reducing errors. It can effectively solve the data error of the machined parts caused by the machine tool eccentricity, improve the workpiece yield, increase production efficiency, and reduce labor costs.

[0037] Furthermore, the compensation components include an X-axis compensation component 7 and a Y-axis compensation component 8. The X-axis compensation component 7 is located between the mounting base 4 and the machining tool 5, and is used to drive the machining tool 5 to move along the X-axis direction. The Y-axis compensation component 8 is located between the mounting bracket 31 and the mounting base 4, and is used to drive the machining tool 5 to move along the Y-axis direction.

[0038] 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.

[0039] Furthermore, both the X-axis compensation assembly 7 and the Y-axis compensation assembly 8 include a fixed base 71, on which a rotary driver 72 is mounted. A positioning block 73 is mounted on the end of the fixed base 71 away from the rotary driver 72. An external lead screw 74 is provided between the rotary driver 72 and the positioning block 73. A movable block 75 is mounted on the external lead screw 74. An internal threaded block 76 is installed inside the movable block 75, and the internal threaded block 76 is threadedly connected to the external lead screw 74. The rotary driver 72 drives the external lead screw 74 to rotate, and the movable block 75 moves axially along the external lead screw 74 through the internal threaded block 76.

[0040] It should be noted that the rotary driver 72 drives the outer lead screw 74 to rotate, the positioning block 73 is used to support the outer lead screw 74, and the inner lead block 76 is fixed inside the movable block 75. The rotation of the outer lead screw 74 drives the movable block 75 to move through the inner lead block 76.

[0041] Furthermore, the mounting base 4 has a compensation chamber 41 inside, the X-axis compensation component 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 component 7.

[0042] It should be noted that the movable block 75 of the X-axis compensation component 7 is fixed to the machining tool 5 and is used to drive the machining tool 5 to move along the X-axis direction.

[0043] Furthermore, a connecting block 42 is fixedly provided at one end of the mounting base 4, and the connecting block 42 passes through the interior of the mounting frame 31. The Y-axis compensation component 8 is installed on the mounting frame 31, and the movable block 75 of the Y-axis compensation component 8 is connected to the connecting block 42.

[0044] It should be noted that the mounting bracket 31 has a groove at the position corresponding to the connecting block 42, and the movable block 75 of the Y-axis compensation component 8 drives the mounting base 4 to move along the groove, i.e., the Y-axis direction.

[0045] Furthermore, guide grooves 78 are provided on both sides of the fixed base 71, and a guide block 77 is fixedly provided on one end of the movable block 75 corresponding to the fixed base 71. The guide block 77 is L-shaped and one end of the guide block 77 is slidably disposed inside the guide groove 78.

[0046] It should be noted that the guide groove 78 is arranged along the axial direction of the outer lead screw 74 and is used to guide the movement of the movable block 75.

[0047] Furthermore, the three-axis drive 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.

[0048] 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.

[0049] In this embodiment, the specific implementation scenario is as follows: For ease of understanding, the following explanation focuses on the compensation of errors generated on the X and Y axes. When the workpiece is assembled on the workpiece fixture 6 and the first workpiece is being machined, the machining tool 5 first locates the original center coordinate point of the machine tool 1 via the detection probe 52. By comparing the first coordinate with the original coordinate of the reference coordinate module 21, the original center coordinate point of the machining tool 5 is recorded as the first coordinate. Due to temperature differences and thermal expansion and contraction, the machine tool 1 experiences a concentricity error, causing the machining tool 5 to deviate from the first coordinate. Therefore, the actual coordinate of the machining tool 5 is recorded as the second coordinate. By comparing the second coordinate with the original coordinate of the reference coordinate module 21, the compensation is obtained. When the deviation coordinate value of the tool 5 is -n or -m, the X-axis compensation component 7 and the Y-axis compensation component 8 compensate for the coordinate value to be +n or +m. That is, the X-axis compensation component 7 and the Y-axis compensation component 8 perform reverse compensation of the same value based on the obtained deviation coordinate value. The overall compensation is performed by the machine tool automatically centering the reference coordinate module 21 and the machine tool automatically enters the coordinates to achieve the goal of concentricity. Before each centering or finishing cutter operation, the detection probe 52 is used to center the tool at the reference coordinate module 21 and automatically enter the total coordinates. The X-axis compensation component 7 and the Y-axis compensation component 8 are used to re-align and correct the eccentricity caused by various factors, thereby obtaining a more accurate concentricity.

[0050] Refer to the instruction manual appendix Figure 4 , Figure 6 and Figure 7 The reference base 2 has an air blowing seat 22 installed inside, and the air blowing seat 22 is located below the reference coordinate module 21. The outer side of the air blowing seat 22 is connected to a nozzle 23, and several sets of nozzles 23 are arranged around the outer side of the reference coordinate module 21.

[0051] It should be noted that the reference coordinate module 21 is cleaned by blowing air onto it through the nozzle 23, ensuring that the reference coordinate module 21 is clean and tidy.

[0052] Furthermore, a processing block 221 is installed in the middle of the air blowing seat 22. Above the processing block 221 is an air outlet chamber 225, and below the processing block 221 is an air inlet chamber 226.

[0053] It should be noted that cold air is supplied to the air blowing seat 22 through the air inlet chamber 226, the cold air passes through the processing block 221 and enters the air outlet chamber 225, and is finally blown out through the nozzle 23.

[0054] Furthermore, a cooling pipe 222 is installed inside the processing block 221, and a dispersing mesh plate 223 is provided above the cooling pipe 222. An elastic filler 224 is filled in the middle of the dispersing mesh plate 223.

[0055] It should be noted that the cooling pipe 222 is connected to an external water pipe, and the elastic filler 224 includes several elastic balls of different diameters.

[0056] In this embodiment, the specific implementation scenario is as follows: To ensure the coordinate reference of the reference coordinate module 21, air blowing is used to clean the reference coordinate module 21 by setting an air blowing seat 22 and a nozzle 23. The nozzles 23 are arranged in pairs around the outer periphery of the reference coordinate module 21. Cold air is input into the air blowing seat 22 through the air inlet chamber 226 and blown onto the reference coordinate module 21 through the nozzles 23. In order to reduce the impact 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. Cold water is circulated inside the cooling pipe 222 to reduce the temperature inside the air blowing seat 22, thereby ensuring that the cold air is delivered at a low temperature within the air blowing seat 22. Due to the concentrated flow of cold air... The air enters from the inlet chamber 226, causing the airflow to enter different nozzles 23 at different speeds. When the blowing speed of a certain nozzle 23 is too fast, it will disrupt the blowing speed balance between two opposing nozzles 23, causing the reference coordinate module 21 to sway towards the nozzle 23 with slower speed, affecting the reference function of the reference coordinate module 21. Therefore, by filling the inside of the dispersion mesh plate 223 with elastic fillers 224, when high-speed gas blows through, the airflow is dispersed by several elastic fillers 224, so that the airflow entering the outlet chamber 225 is evenly dispersed, thereby reducing the blowing speed difference between multiple nozzles 23, making the blowing speed of multiple nozzles 23 relatively uniform, and avoiding the reference coordinate module 21 from being affected by swaying.

[0057] Refer to the instruction manual appendix Figure 8 The present invention also provides a method for applying an automatic concentricity compensation tool, comprising the following steps:

[0058] S1: Design and install a high-precision reference module, which is fixed on the machine tool's worktable and whose coordinates serve as reference coordinate points for all subsequent operations;

[0063] S6: Repeat steps S3-S5 for the next processing.

[0064] The above embodiments merely illustrate several implementation methods of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention.
