[0002] In the CNC machine tool manufacturing industry, precision testing of CNC equipment is a crucial step in the manufacturing process. Currently, the testing of self-manufactured CNC equipment typically relies on expensive high-end testing instruments such as ballbars and laser measuring machines, which cost anywhere from tens of thousands to millions of yuan. For small-scale manufacturing companies, investing heavily in equipment testing during the initial stages of a project can be a significant burden. To reduce costs and increase efficiency, a more robust testing device is needed to replace these high-end instruments. Therefore, a device was designed that utilizes a standard square ruler in conjunction with the relative movement of the CNC lathe's X-axis and the CNC tool post's Y-axis to test the Y-axis tool post.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0021] In the description of this utility model, it should be noted that the orientation or positional relationship indicated by terms such as "center", "up", "down", "left", "right", "vertical", "horizontal", "inner", and "outer" are based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.
[0022] A device for detecting the axial movement of CNC functional components, such as... Figure 1 , 3As shown, the fixture includes a clamping body 1, a fixture base plate 2, a height equalizing pad 3, a standard square 4, a fixture body length side plate 5, a pressure plate 6, a center pressure screw 7, a center pressure washer 8, a pressure screw 9, a pressure plate connecting screw 10, a fixture body short side plate 11, and a fine-tuning screw 12. The clamping body 1, the fixture base plate 2, and the height equalizing pad 3 are connected and fixed sequentially from bottom to top. The fixture body length side plate 5 and the fixture body short side plate 11 are respectively fixed to the long and short sides of the fixture base plate 2. The standard square 4 is connected to the fixture body through the center pressure washer 6. The tightening screw 7 and the clamping washer 8 are fixedly arranged above the leveling pad 3 and are tightened by the clamping screw 9. The clamping screw 9 is fixed on the long side plate 5 and the short side plate 11 of the clamp body through the clamping plate connecting screw 10 and the clamping plate 6. The fine adjustment screw 12 is respectively provided on the outer side of the long side plate 5 and the short side plate 11 of the clamp body. The fine adjustment screw 12 passes through the long side plate 5 and the short side plate 11 of the clamp body and abuts against the long and short sides of the standard square ruler 4.
[0023] Specifically, the clamping body 1, the fixture base plate 2, and the leveling block 3 are sequentially connected and fixed, ensuring the stability and accuracy of the testing platform. The leveling block 3 allows for fine-tuning of the height of the standard square ruler 4 to adapt to the needs of different parts to be tested, improving the flexibility and adaptability of the testing. The fine-tuning screw 12 passes through the long side plate 5 and the short side plate 11 of the fixture body and abuts against the long and short sides of the standard square ruler 4, allowing for minor adjustments to the standard square ruler 4, further ensuring the accuracy of the testing and compensating for minor deviations caused by manufacturing tolerances or installation errors. The long side plate 5 and the short side plate 11 of the fixture body not only provide a secure connection for the clamping plate 6, the clamping screw 9, and the fine-tuning screw 12, but also provide a secure connection for the clamping plate 6, the clamping screw 9, and the fine-tuning screw 12. The mounting position and robust structure enhance the stability of the entire testing platform. The modular design allows for independent replacement or upgrade of individual components, improving the maintainability and scalability of the testing platform. The use of clamping plate 6 and clamping screw 9 ensures the stability of the standard square ruler 4 during the testing process, simplifies the fixing process of the standard square ruler 4, and improves testing efficiency. The standard square ruler 4 is set with an accuracy of 00 or higher, serving as a high-precision measurement benchmark. The introduction of the standard square ruler 4 ensures the accuracy of the testing results. Its high-precision machining and stable performance provide a reliable reference standard for evaluating the accuracy of the parts under test during the testing process. After connecting the assembled fixture to the CNC lathe spindle, align the CNC lathe X-axis with the standard square working surface 1. This step is suitable for horizontal lathes with flat or slant beds. After alignment, lock the spindle. Fine-tuning can also be done using the fine-adjusting screw 12. Then connect the fixture to the CNC lathe spindle and use a dial indicator to align the fixture surface 1 with the machine tool X-axis. Parallelism can also be adjusted by the fine-adjusting screw or by rotating the machine tool spindle. After parallelism alignment, the Y-axis perpendicularity accuracy, Y-axis backlash, Y-axis repeatability accuracy, and Y-axis crawling accuracy of the tool post can be tested. The overall structure is simple, the manufacturing cost is low, and it is easy to assemble and disassemble. A single clamping can simultaneously complete some routine tests in the manufacturing of machine tool functional components, such as perpendicularity testing, backlash testing, repeatability accuracy testing, and crawling testing. It is also highly adaptable and can be used on most common horizontal and slant beds on the market.
[0024] As a preferred embodiment of the above, such as Figure 1 As shown, the equal height pad 3 is set as four pads of the same horizontal height, which are respectively set at the four corners below the standard square 4.
[0025] Specifically, by setting the equal height pads 3 as four pads of the same horizontal height and placing them at the four corners below the standard square 4, the stability and balance of the standard square 4 during the inspection process can be ensured, avoiding inspection errors caused by inconsistent heights or uneven distribution of the pads, and improving the accuracy and reliability of the inspection.
[0026] As a preferred embodiment of the above, such as Figure 1 As shown, the center clamping screw 7 and the clamping washer 8 are fixed by the center position of the standard square ruler 4.
[0027] Specifically, by using the fine-tuning screw 12, the standard square ruler 4 can be slightly rotated around its center while maintaining its fixed stability, in conjunction with the center clamping screw 7. This allows the operator to flexibly adjust the position of the long and short sides of the standard square ruler 4 according to specific measurement needs, thereby improving the flexibility and adaptability of the measurement. The slight rotation adjustment by the fine-tuning screw 12 ensures that the standard square ruler 4 maintains optimal contact with the part to be measured during the measurement process. Precise adjustment helps reduce measurement errors caused by positional deviations, thereby improving the accuracy and reliability of the measurement.
[0028] As a preferred embodiment of the above, such as Figure 1 As shown, four fine-tuning screws 12 are provided, with two groups disposed at each end of the long side plate 5 and the short side plate 11 of the clamp body.
[0029] Specifically, the use of four fine-tuning screws 12 allows for more precise adjustments to the minute positions of the long side plate 5 and the short side plate 11 of the clamping body. By adjusting these four screws individually, minor tilts or offsets of the clamping body can be corrected, thereby improving overall stability and accuracy.
[0030] As a preferred embodiment of the above, such as Figure 1 As shown, there are four clamping screws 9, two in a group, located at the positions where the two clamping plates 6 extend to the standard square ruler 4.
[0031] Specifically, the standard square ruler 4 can be more tightly and securely fixed by two sets of clamping screws 9 set on the two clamping plates 6. This design helps reduce measurement or processing errors caused by unstable fixing, improves overall accuracy and quality, and prevents the standard square ruler 4 from shaking or shifting during measurement or processing. The four clamping screws 9 allow operators to complete the fine-tuning of the standard square ruler 4 more quickly and accurately, quickly judge and adjust the fixing status, thereby simplifying the operation process and improving work efficiency.
[0032] As a preferred embodiment of the above, such as Figure 2 As shown, there are four clamping plate connecting screws 10, which are arranged in two groups on the two clamping plates 6 above the long side plate 5 and the short side plate 11 of the clamping body.
[0033] Specifically, the four clamping plate connecting screws 10 ensure a more secure connection between the clamping plate 6 and the long side plate 5 and short side plate 11 of the clamping body. This design helps reduce displacement or deformation of the clamping plate 6 due to unstable connections, thereby improving overall connection stability and reliability, and ensuring that the clamping plate 6 maintains its optimal position and condition during measurement or processing. This helps reduce measurement or processing errors caused by unstable connections, improving overall accuracy and quality.
[0034] As a preferred embodiment of the above, such as Figure 2 As shown, the two clamping screws 9 are arranged in pairs, parallel to the long side plate 5 or the short side plate 11 of the clamp body, according to the standard square 4.
[0035] As a preferred embodiment of the above, such as Figure 2 As shown, the two clamping plate connecting screws 10 are set parallel to the long side plate 5 or the short side plate 11 of the clamping body according to the standard square 4.
[0036] Specifically, by ensuring that the clamping screw 9 and the clamping plate connecting screw 10 are parallel to the long side plate 5 or the short side plate 11 of the clamping body, a more uniform and stable fixation of the standard square ruler 4 can be achieved. This helps reduce uneven clamping force caused by screw tilting or misalignment, thereby improving overall fixation stability. Parallel screws make it easier to achieve uniform tightening and avoid mutual interference between screws due to different tightening degrees. This helps enhance the screw tightening effect, ensuring that the standard square ruler 4 will not shift or deform due to unstable fixation during measurement or processing. The parallel screws also allow operators to complete the fine-tuning and fixing of the standard square ruler 4 more quickly and accurately.
[0037] As a preferred embodiment of the above, such as Figure 2 As shown, the spacing between the two sets of clamping plate connecting screws 10 on the clamping plate 6 is greater than the spacing between the clamping screws 9.
[0038] Specifically, by maintaining a stable connection between the clamping plate 6 and the clamping body, a larger operating space and adjustment range are provided for the clamping screws 9. The larger spacing of the clamping plate connecting screws 10 ensures that the clamping plate 6 can evenly distribute pressure when subjected to external forces, avoiding deformation or damage caused by excessive force at a single point. At the same time, the larger spacing also provides more flexibility in the arrangement and fine-tuning of the clamping screws 9, allowing operators to more accurately adjust the position and angle of the standard square 4.
[0039] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
