Description

Technical Field

[0001] This utility model belongs to the field of CNC rotary table rotation accuracy measurement, and is a laser rotary axis calibration device and a CNC rotary table rapid concentricity adjustment platform. Background Technology

[0002] In the rotational accuracy testing of CNC machine tool turntables, the rotation axis calibration device 3 of the laser interferometer is a key component of the laser interferometer. Its rotational accuracy is very high. However, to ensure that the measurement results are true and accurate, the concentricity between the rotation axis calibration device 3 of the laser interferometer and the CNC turntable must meet the requirements.

[0003] like Figure 1 As shown, there is currently no platform on the market specifically designed for rapid concentricity adjustment of the laser rotary axis calibration device and the CNC rotary table. Existing technologies mostly rely on on-site fabrication of tooling fixtures, which cannot quickly adjust the relative position of the rotary axis calibration device and the rotation center of the CNC rotary table during the adjustment process, resulting in lengthy auxiliary adjustment times and impacting measurement efficiency.

[0004] Defects and shortcomings of existing technology:

[0005] Unable to quickly and accurately establish concentricity between the two: In the existing technology, the relative position of the CNC rotary table and the rotary axis calibration device 3 is difficult to adjust quickly and accurately, resulting in a large measurement error.

[0006] Poor adaptability: The existing fixing method cannot adapt to the size differences of the rotary table of different CNC machine tools, which limits its rapid application on medium and large equipment. Utility Model Content

[0007] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a laser rotary axis calibration device and a CNC rotary table rapid concentricity adjustment platform. The core issue of this application is how to accurately and quickly establish the concentricity of the laser rotary axis calibration device and the CNC rotary table, thereby achieving high-precision rotary accuracy measurement.

[0008] The technical solution adopted by this utility model to solve the technical problem is:

[0009] This utility model provides a laser rotary axis calibration device and a CNC rotary table rapid concentricity adjustment platform, including: an XY horizontal adjustment table and a magnetic fixing platform. The magnetic fixing platform includes: a support base, three adjustable support legs, and three magnetic seats. The top surface of the support base is fixed to the bottom of the XY horizontal adjustment table. The three adjustable support legs are evenly distributed on the support base and rotatably connected to the bottom surface of the support base. The adjustable support legs are locked to the support base by locking bolts. A magnetic seat is installed at the end of each adjustable support leg away from the support base.

[0010] Furthermore, it also includes a central positioning seat, which is installed in the middle of the top surface of the XY horizontal adjustment platform.

[0011] Furthermore, the central positioning seat is a circular boss.

[0012] Furthermore, it also includes two pressure blocks, symmetrically installed on the top surface of the XY horizontal adjustment platform.

[0013] Furthermore, the pressure block is adjustablely mounted on the XY horizontal adjustment platform by internal screws. The top of the pressure block is a pressure cap. Loosen the screws, adjust the two pressure blocks, and when the arc-shaped edge of the pressure cap on the top of the pressure block points to the center, tighten the screws to fix it, pressing the connecting seat against the XY horizontal adjustment platform.

[0014] Furthermore, the support base is also provided with multiple openings.

[0015] The advantages and positive effects of this utility model are:

[0016] 1. Quickly establish the concentricity between the rotary axis calibration device and the CNC turntable: This utility model uses a dual structure of XY horizontal adjustment table and magnetic fixing platform to realize two-dimensional adjustment in the horizontal direction and rotation adjustment of the support leg of the magnetic fixing platform, increasing the degree of adjustment freedom and enabling quick adjustment of the concentricity between the CNC turntable and the laser rotary axis calibration device 3.

[0017] 2. High-precision adjustment: The XY horizontal adjustment table of this utility model can provide an adjustment accuracy of up to 0.01mm, which can quickly and accurately adjust the concentricity between the CNC turntable and the rotary axis calibration device 3, ensuring that the measurement results are true and accurate.

[0018] 3. High adaptability: The adjustable support legs of the magnetic fixing platform of this utility model have good adaptability and can adapt to the size of the positioning ring of the turntable of different CNC machine tools, making it suitable for various medium and large-sized equipment.

[0019] 4. Improved work efficiency: The magnetic base quick-adjustment design of this utility model platform greatly reduces the time for on-site fabrication and adjustment of fixtures, thereby improving work efficiency. Attached Figure Description

In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0030] like Figures 2-5 As shown, this utility model provides a laser rotary axis calibration device and a CNC rotary table rapid concentricity adjustment platform, including: an XY horizontal adjustment table 1 and a magnetic fixing platform 2.

[0031] like Figure 4The diagram shows the structure of the XY horizontal adjustment table 1 of this invention. The XY horizontal adjustment table 1 of this invention can adopt the same structure and usage method as existing cross-guide rail type displacement slides, steel bar ball type displacement slides, linear steel ball type displacement slides, or dovetail groove type displacement slides to achieve precise adjustment and fixation. The top of the XY horizontal adjustment table 1 is directly concentrically connected to the laser rotary axis calibration device 3 and the connecting seat 4. It is manufactured with high precision to ensure accurate and rapid adjustment of the relative position between the laser rotary axis calibration device 3 and the CNC turntable. The XY horizontal adjustment table 1 moves in the X and Y axes through adjustment components (such as micrometer heads, precision screw sets, and precision screws), providing high-precision adjustment of 0.01mm to ensure that the concentricity between the rotary axis calibration device 3 and the CNC turntable meets the requirements.

[0032] like Figure 4 As shown, to facilitate the positioning of the connecting seat 4 of the laser interferometer, a center positioning seat 11 is installed in the center of the top surface of the XY horizontal adjustment stage 1. The center positioning seat 11 is a circular boss. For easy fixing, two pressure blocks 12 are symmetrically installed on the top surface of the XY horizontal adjustment stage 1. The pressure blocks 12 are adjustablely mounted on the XY horizontal adjustment stage 1 by internal screws. The top of the pressure block 12 is a pressure cap. Loosen the screws, adjust the two pressure blocks 12 until the arc-shaped edge of the pressure cap on the top of the pressure block 12 points to the center, then tighten the screws to fix it, pressing the connecting seat 4 tightly against the XY horizontal adjustment stage 1. The XY horizontal adjustment stage 1 of this invention also supports fine-tuning during installation to ensure accurate and rapid adjustment of the relative position between the rotary axis calibration device 3 and the CNC rotary table.

[0033] like Figure 5As shown, the magnetic fixing platform 2 includes: a support base 21, three adjustable support legs 22, and three magnetic seats 23. The top surface of the support base 21 is fixed to the bottom of the XY horizontal adjustment platform 1. The three adjustable support legs 22 are evenly distributed on the support base 21 and rotatably connected to the bottom surface of the support base 21. The adjustable support legs 22 are locked to the support base 21 by locking bolts. A magnetic seat 23 is installed on the end of each adjustable support leg 22 away from the support base 21. In addition, multiple openings 211 are made on the support base 21, which reduces weight and prevents the overall device from being too heavy, and also makes it easy to pick up and carry. When not in use, the adjustable support legs 22 of the adaptive magnetic fixing platform 2 can be rotated and retracted to the bottom of the support base 21, saving space and improving the utilization rate of the storage box. The three adjustable support legs 22 of the adaptive magnetic fixing platform 2 of this utility model are rotatably adjustable to adapt to the size of different machine tool turntables, ensuring that the rotary axis calibration device 3 is stably installed and remains concentric with the CNC rotary table 5. This utility model allows for precise and rapid concentric adjustment of the laser turntable by loosening the locking bolts to adjust the demagnetizing characteristics of the support legs 22, support base 21, and magnetic base 23, ensuring that the rotation path of the CNC turntable is consistent with the rotary axis calibration device 3. By tightening the locking bolts to adjust the magnetizing characteristics of the support legs 22, support base 21, and magnetic base 23, the laser circuit can remain stable when the laser turntable rotates, avoiding measurement errors caused by unstable fixing.

[0034] The method of using this utility model is as follows:

[0035] During installation, after the laser rotary axis calibration device 3 is fixed to the connecting seat 4 by the movable pressure plate, the connecting seat 4 is aligned with the center positioning seat 11 at the top of the XY horizontal adjustment stage 1 in this device and fixed with the pressure block 12. The assembled rotary axis calibration device 3, connecting seat 4, laser rotary axis calibration device and CNC rotary table quick concentricity adjustment platform are placed on the rotary table 5 of the machine tool. According to the size of the rotary table 5, the rotation angle of the adjustable support leg 22 on the adaptive magnetic fixing platform 2 is adjusted. After fitting, the adjustable support leg 22 and the support seat 21 are locked with locking bolts and fixed to the rotary table 5 of the machine tool by magnetic seat 23. During measurement, the XY horizontal adjustment stage 1 is moved in the X and Y axis directions by the adjustment components on the XY horizontal adjustment stage 1, providing high-precision adjustment of 0.01mm to ensure that the measurement results are true and accurate.

[0036] This invention's laser rotary mirror precision adaptive rapid adjustment platform, through the precise design of the XY horizontal adjustment stage 1 and the adaptive magnetic fixing platform 2, compensates for the inconvenience of adjusting the included adapter when compensating for medium and large CNC rotary stages. It enables rapid adjustment of the concentricity between the laser rotary axis calibration device and the CNC rotary stage, accommodating rapid concentricity adjustments for various medium and large rotary stages and laser rotary axis calibration devices. Throughout the measurement process, the rotation path of the CNC rotary stage and the laser rotary axis calibration device 3 remain precisely aligned, ensuring the accuracy and reliability of the measurement results.

[0037] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
