Description

Technical Field

[0001] The present application relates to the technical field of CNC milling machine positioning, and in particular to an intelligent set of high-efficiency integrated detection and positioning equipment and a positioning method thereof. Background Art

[0002] A CNC milling machine is an automatic processing equipment developed on the basis of a general milling machine. The processing techniques of the two are basically the same, and the structures are somewhat similar. Its main structure includes a processing body, a processing spindle installed at the upper end of the processing body, a Y-axis moving platform installed at the bottom end of the processing body, an X-axis moving platform installed on the Y-axis moving platform, a fixture installed on the Y-axis moving platform, and a control panel installed on one side of the processing body for controlling the X-axis moving platform, the Y-axis moving platform and the processing spindle for processing. The fixture is mainly composed of a fixed plate and a sliding plate and fixing bolts for fixing the sliding plate. Before processing a workpiece with the prior art, the workpiece needs to be placed in the fixture so that the fixture clamps the workpiece. Then the staff installs the tool on the processing spindle and starts the processing spindle to rotate at the same time. Then, the tool is used to The main method is to control the machining spindle to move downward through the control panel so that the end face of the tool touches the upper surface of the workpiece, and then the staff sets the current position of the tool as the origin of the Z axis, and then controls the X-axis moving platform to move left or right through the control panel so that the tool touches the left or right side of the workpiece and then resets the moving distance of the X-axis moving platform to zero, and then controls the X-axis moving platform to move so that the tool touches the other side of the workpiece, and then divides the moving distance of the X-axis moving platform by 2 to obtain the origin of the X axis of the workpiece. The origin of the Y axis is obtained in the same way as the X axis, and it is only necessary to control the Y-axis moving platform to move so that the tool touches the front and back sides of the workpiece. Through the above operations, the tool is facing the center of the workpiece to complete the positioning of the workpiece, and then the staff can program the tool to process the workpiece through the control panel.

[0003] The positioning method in the prior art is not only cumbersome in steps, but also requires manual control of the processing spindle, X-axis mobile platform and Y-axis mobile platform, which leads to some deviations in the positioning of the origin, making its positioning efficiency low. In addition, the deviation affects the processing accuracy, resulting in an increase in the defective rate. For this reason, the present application proposes an intelligent set of high-efficiency integrated detection and positioning equipment and a positioning method thereof, so as to reduce manual intervention, improve processing accuracy and reduce the defective rate. Summary of the invention

[0004] In view of the shortcomings of the prior art, the purpose of this application is to provide an intelligent set of high-efficiency integrated detection and positioning equipment and a positioning method thereof, so as to reduce the manual intervention in the positioning of the workpiece origin in the prior art, thereby improving the processing accuracy and reducing the defective rate.

[0005] The above-mentioned purpose of the present application is achieved through the following technical solutions: an intelligent complete set of high-efficiency detection and positioning integrated equipment, including a processing body, a processing spindle installed at the upper end of the processing body, a Y-axis mobile platform installed at the bottom end of the processing body, an X-axis mobile platform installed on the Y-axis mobile platform, and a control panel installed on one side of the processing body for controlling the X-axis mobile platform, the Y-axis mobile platform and the processing spindle for processing, a positioning system for automatically aligning the workpiece with the tool is installed on the X-axis mobile platform, the positioning system includes an X-axis fixed structure and a Y-axis fixed structure, and the X-axis fixed structure includes A storage slot is provided on the X-axis movable platform, two driving electric cylinders are arranged inside the storage slot and are symmetrically arranged with the center of the X-axis movable platform as the midpoint, and a clamping plate is fixedly arranged on the output end of the driving electric cylinder and extends upward from the storage slot. In the initial state, the center of the X-axis movable platform is opposite to the center of the machining spindle. The Y-axis fixed structure is the same as the X-axis fixed structure, but the Y-axis fixed structure is arranged along the Y-axis direction of the X-axis movable platform, and the storage slot of the Y-axis fixed structure intersects with the storage slot of the X-axis fixed structure. The driving electric cylinder circuit is connected to the control panel, and the output end of the driving electric cylinder extends toward the outside of the X-axis movable platform.

[0006] By adopting the above technical solution, when the staff needs to position the workpiece, they only need to place the workpiece at the intersection of the storage slot of the Y-axis fixed structure of the X-axis moving platform and the storage slot of the X-axis fixed structure, and then start the X-axis moving platform, the Y-axis moving platform and the processing spindle through the control panel to reset to the initial state, and then start the driving electric cylinder to make the output end of the driving electric cylinder contract toward the center of the X-axis moving platform, and at the same time drive the clamping plate to move toward the center of the X-axis moving platform, so that the clamping plates in the X-axis fixed structure and the Y-axis fixed structure respectively clamp the side walls of the workpiece, and because the four driving electric cylinders are The X-axis moving platform is symmetrically arranged with the center of the X-axis moving platform as the midpoint, so that after the clamping plate clamps the workpiece, the center of the workpiece is automatically aligned with the center of the tool. At this time, the staff only needs to set this point as the workpiece X-axis and the origin of the X-axis, and then control the machining spindle to move down through the control panel so that the end face of the tool touches the upper surface of the workpiece to complete the Z-axis origin setting. In this way, the workpiece is fixed and the positioning of the workpiece is completed, and the positioning step is very simple. It only needs to start the driving electric cylinder, thereby reducing the manual intervention of the workpiece origin positioning and achieving the purpose of improving machining accuracy and reducing the defective rate.

[0007] Furthermore, the portion of the clamping plate extending out of the receiving groove is provided with a protective structure for reducing the friction of the clamping plate with the workpiece.

[0008] Furthermore, the protective structure includes a slide groove opened on one side of the clamping plate close to the center of the X-axis moving platform, a slide bar slidably connected to the clamping plate through the slide groove, and a slide plate fixedly set on the side of the slide bar away from the slide groove and with an area larger than the slide groove, the slide bar is covered with the slide groove, and the slide groove is horizontally arranged on the clamping plate.

[0009] By adopting the above technical solution, although the setting of the positioning system improves the processing accuracy and reduces the defective rate, the length and width of each workpiece are different, which results in that the clamping plate of one of the Y-axis fixed structure and the X-axis fixed structure in the positioning system will complete the clamping first, and then the fixed structure that completes the clamping will push the workpiece to rub the clamping plate of the fixed structure that completes the clamping first, resulting in the loss of the clamped side wall of the workpiece, and the processing tool cannot contact the clamped part of the workpiece, resulting in reduced workpiece accuracy. The setting of the protective structure solves this technical problem. For example: when the clamping plate in the Y-axis fixed structure clamps the workpiece first, the clamping plate in the Y-axis fixed structure contacts the side wall of the workpiece through the slide plate. When the clamping plate in the X-axis fixed structure clamps the other two sides of the workpiece, its clamping plate will push the workpiece to move in the direction of the X-axis. At the same time, the slide plate on the clamping plate in the Y-axis fixed structure will also move in the direction of the X-axis, so that the workpiece will not rub the clamping plate in the Y-axis fixed structure, and will not cause the loss of the clamped side wall of the workpiece, which can prevent the workpiece accuracy from being reduced and improve the stability of the positioning system.

[0010] Furthermore, a side of the slide groove away from the slide plate is provided with a reset structure for resetting the slide plate, and the reset structure includes a reset groove opened on the side of the slide groove away from the slide plate, a reset block fixedly arranged on the side of the slide bar away from the slide plate, and a reset spring arranged on both sides of the reset groove for pushing the reset block to be centered in the reset groove, one end of the reset block is fixedly connected to the slide bar, and the other end extends into the reset groove, and the reset block is arranged in the middle of the slide bar, and the reset groove is arranged along the length direction of the slide groove, one end of the reset spring is fixedly connected to the side wall of the reset groove, and the other end abuts against one side of the reset block.

[0011] By adopting the above technical solution, although the setting of the protective structure improves the stability of the positioning system, each time the positioning system is used, the staff needs to push the slide to reset the slide, which is very inconvenient. The setting of the reset structure solves this technical problem. When the slide slides along the slide groove, it will compress one of the reset springs on both sides of the reset groove. When the staff starts the extension of the drive electric cylinder through the control panel, the clamping plate will move away from the workpiece and no longer clamp the workpiece. At this time, the slide loses pressure on the workpiece, and the reset spring will push the reset block to move to the center of the reset groove, so that the slide bar drives the slide to reset. In this way, the staff does not need to manually reset the slide, thereby improving the convenience of the positioning system.

[0012] Furthermore, a positioning device for positioning the Z-axis origin is provided on one side of the machining spindle.

[0013] Furthermore, the positioning device includes a positioning electric cylinder fixedly arranged on one side of the machining spindle, a positioning plate installed on the output end of the positioning electric cylinder, and a pressure sensor arranged on the bottom surface of the positioning plate. The pressure sensor signal is connected to the control panel and is used to start and stop the lifting and lowering of the machining spindle through the control panel. The output end of the positioning electric cylinder faces downward.

[0014] By adopting the above technical solution, although the setting of the positioning system reduces the manual intervention in the positioning of the workpiece origin, the positioning of the origin of the Z-axis still requires manual control of the machining spindle to descend so that the tool can cut the upper surface of the workpiece before it can be completed. This leads to a certain deviation in the positioning of the origin. Because the manual control of the machining spindle descent requires the tool to cut the workpiece before it can determine whether the tool contacts the workpiece, after the Z-axis origin positioning is completed, it is necessary to cut the entire upper surface of the workpiece with the current position of the tool, which is very troublesome. The setting of the positioning device solves this technical problem. Through the setting of the positioning device, when the staff locates the origin of the Z-axis, they only need to start the positioning electric cylinder so that the output end of the positioning electric cylinder extends downward until the pressure sensor is coplanar with the end face of the tool. Then, there is no need to start the rotation of the machining spindle. It is only necessary to start the machining spindle to descend. After descending until the pressure sensor contacts the upper surface of the workpiece, the pressure sensor sends a stop signal to the control panel, and the control panel stops the descent of the machining spindle. At this time, the origin positioning of the Z-axis is completed, and there is no need to cut the upper surface of the workpiece, which further reduces the deviation of manual positioning, improves the machining accuracy, and reduces the defective rate.

[0015] Furthermore, a positioning shell is fixedly connected to the output end of the positioning electric cylinder, and a through hole penetrating the positioning shell is opened on a side of the positioning shell close to the machining spindle and a bottom surface thereof. The positioning plate is laterally slidingly connected in the positioning shell, and the pressure sensor extends out of the positioning shell. The positioning plate is installed on the output end of the positioning electric cylinder through the positioning shell.

[0016] By adopting the above technical scheme, although the setting of the positioning device further reduces the deviation of manual positioning, improves the processing accuracy and reduces the defective rate, the positioning device cannot be set too close to the processing spindle, otherwise it will affect the operation of the processing spindle. However, if it is set too far away from the processing spindle, when the CNC milling machine processes a smaller workpiece, the pressure sensor of the positioning device cannot contact the upper surface of the workpiece. The setting of the positioning shell solves this technical problem. Through the setting of the positioning shell, when the CNC milling machine processes a smaller workpiece, the staff can pull the positioning plate to move toward the processing spindle, so that the positioning plate slides out of the positioning shell, so that the positioning plate can be closer to the processing spindle, so that the pressure sensor on the bottom of the positioning plate can contact the upper surface of the smaller workpiece for positioning, and the setting of the positioning shell also allows the staff to pull the positioning plate out of the positioning shell, so that the staff can easily replace and repair the pressure sensor.

[0017] Furthermore, a fixing structure for fixing the positioning block is provided on one side of the positioning shell, and the fixing structure includes fixing holes opened on the left and right sides of the positioning block and passing through the positioning block, and a fixing rod arranged on the side of the positioning block close to the machining spindle and passing through the positioning shell and plugged into the positioning shell.

[0018] By adopting the above technical solution and setting the fixing structure, the positioning block can be installed in the positioning housing more stably.

[0019] The positioning method of the intelligent complete set of efficient detection and positioning integrated equipment applied in the above technical solution comprises the following steps: S1, placing the workpiece at a position where the storage slot of the Y-axis fixed structure of the X-axis moving platform intersects with the storage slot of the X-axis fixed structure; S2, start the X-axis moving platform, the Y-axis moving platform and the machining spindle through the control panel and reset them to the initial state; S3, start the driving electric cylinder, so that the output end of the driving electric cylinder contracts toward the center of the X-axis moving platform, and at the same time drives the clamping plate to move toward the center of the X-axis moving platform, so that the clamping plates in the X-axis fixed structure and the Y-axis fixed structure clamp the side walls of the workpiece respectively, completing the X-axis and Y-axis origin positioning of the workpiece; S4, start the positioning electric cylinder so that the output end of the positioning electric cylinder extends downward until the pressure sensor is coplanar with the end face of the tool, and then start the machining spindle to descend. After descending until the pressure sensor contacts the upper surface of the workpiece, the pressure sensor sends a stop signal to the control panel, and the control panel stops the descent of the machining spindle, completing the Z-axis origin positioning of the workpiece.

[0020] In summary, the present application includes at least one of the following beneficial technical effects: Through the setting of the positioning system, after the X-axis moving platform, Y-axis moving platform and machining spindle are reset to the initial state, the staff only needs to place the workpiece at the intersection of the storage slot of the Y-axis fixed structure of the X-axis moving platform and the storage slot of the X-axis fixed structure, and then start the driving electric cylinder to make the clamping plate clamp the workpiece. Due to the characteristics of the positioning system itself, the center of the clamped workpiece is automatically aligned with the center of the tool. At this time, the staff only needs to set this point as the origin of the workpiece X-axis and the X-axis, thereby achieving both fixing the workpiece and completing the positioning of the workpiece, and making the positioning step very simple, and only needs to start the driving electric cylinder, thereby reducing the manual intervention of the workpiece origin positioning, improving the machining accuracy, and reducing the defective rate.

[0023] The present application is further described in detail below in conjunction with the accompanying drawings.

[0024] Example, see Figure 1 , Figure 2The intelligent complete set of high-efficiency detection and positioning integrated equipment includes a processing body 1, a processing spindle 10 installed at the upper end of the processing body 1, and a Y-axis moving platform 11 installed at the bottom of the processing body 1. The Y-axis moving platform 11 can move along a predetermined Y-axis direction. Furthermore, an X-axis moving platform 12 is mounted on the Y-axis moving platform 11, and the X-axis moving platform 12 can move flexibly in the X-axis direction, thereby realizing precise positioning in a two-dimensional plane.

[0025] A fully functional control panel 13 is provided on one side of the processing body 1. This control panel 13 is the command center of the equipment, which is responsible for controlling the coordinated operation of the X-axis mobile platform 12, the Y-axis mobile platform 11 and the processing spindle 10 to ensure the smoothness and accuracy of the entire processing process.

[0026] On the X-axis mobile platform 12, a positioning system 2 for automatically aligning the workpiece with the tool is installed in this embodiment. This positioning system 2 is composed of an X-axis fixed structure 20 and a Y-axis fixed structure 21. The X-axis fixed structure 20 mainly includes a storage groove 22 opened on the X-axis mobile platform 12 and arranged along the X-axis direction of the X-axis mobile platform 12, and two driving electric cylinders 23 symmetrically arranged inside the storage groove 22. The two driving electric cylinders 23 are symmetrically distributed with the center of the X-axis mobile platform 12 as the midpoint, and a clamping plate 24 is fixedly connected to the output end of the driving electric cylinder 23, and the upper end of the clamping plate 24 extends upward from the storage groove 22 to clamp the workpiece.

[0027] The design of the Y-axis fixed structure 21 is similar to that of the X-axis fixed structure 20, but the Y-axis fixed structure 21 is arranged along the Y-axis direction of the X-axis mobile platform 12. In particular, the storage slot 22 of the Y-axis fixed structure 21 and the storage slot 22 of the X-axis fixed structure 20 intersect each other in space, forming a workpiece placement area. The driving electric cylinders 23 of the X-axis fixed structure 20 and the Y-axis fixed structure 21 are both connected to the control panel 13 through circuits, and their output ends both extend toward the outside of the X-axis mobile platform 12, providing strong power support for the clamping of the workpiece.

[0028] When the staff needs to position the workpiece, they simply place the workpiece at the intersection of the storage slot 22 of the Y-axis fixed structure 21 of the X-axis mobile platform 12 and the storage slot 22 of the X-axis fixed structure 20. Then, the X-axis mobile platform 12, the Y-axis mobile platform 11 and the processing spindle 10 are started to reset to their initial states through the control panel 13. At this time, the driving electric cylinder 23 is started again, and their output ends will shrink toward the center of the X-axis mobile platform 12, while driving the clamping plate 24 to move toward the center until the clamping plates 24 in the X-axis fixed structure 20 and the Y-axis fixed structure 21 respectively tightly clamp the side walls of the workpiece.

[0029] Since the four driving electric cylinders 23 are symmetrically arranged with the center of the X-axis moving platform 12 as the midpoint, when the clamping plate 24 clamps the workpiece, the center of the workpiece will automatically and accurately align with the center of the tool. At this time, the staff only needs to set this point as the origin of the X-axis and Y-axis of the workpiece through the control panel 13. Next, the control panel 13 is used to control the machining spindle 10 to move downward until the end face of the tool lightly touches the upper surface of the workpiece, completing the Z-axis origin setting.

[0030] In this way, not only the workpiece is fixed, but also the workpiece is accurately positioned. Moreover, the entire positioning process is very simple and can be completed by simply starting the drive cylinder 23. This innovative design greatly reduces the manual intervention in the process of workpiece origin positioning, thereby significantly improving the processing accuracy and effectively reducing the defective rate.

[0031] Although the setting of the positioning system 2 improves the processing accuracy and reduces the defective rate, the length and width of each workpiece are different, which results in that the clamping plate 24 of one of the Y-axis fixed structure 21 and the X-axis fixed structure 20 in the positioning system 2 will complete the clamping first, and then the fixed structure 6 that completes the clamping will push the workpiece to rub against the clamping plate 24 of the fixed structure 6 that completes the clamping first, resulting in the loss of the side wall of the workpiece being clamped, and the processing tool cannot contact the clamped part of the workpiece, resulting in reduced workpiece accuracy. In order to solve this technical problem, refer to Figure 3 , Figure 4 In this embodiment, a protective structure 3 for reducing the friction of the clamping plate 24 with the workpiece is provided at the portion of the clamping plate 24 extending out of the receiving groove 22. The protective structure 3 includes a slide groove 30 provided on one side of the clamping plate 24 close to the center of the X-axis moving platform 12, a slide bar 31 slidably connected to the clamping plate 24 through the slide groove 30, and a slide plate 32 fixedly provided on the side of the slide bar 31 away from the slide groove 30 and having an area larger than the slide groove 30. The slide bar 31 is covered with the slide groove 30, and the slide groove 30 is horizontally provided on the clamping plate 24. When the clamping plate 24 in the Y-axis fixed structure 21 first clamps the The workpiece, at this time, the clamping plate 24 in the Y-axis fixed structure 21 contacts the side wall of the workpiece through the slide 32, and when the clamping plate 24 in the X-axis fixed structure 20 clamps the other two sides of the workpiece, the clamping plate 24 will push the workpiece to move along the direction of the X-axis, and at the same time, the slide 32 on the clamping plate 24 in the Y-axis fixed structure 21 will also move along the direction of the X-axis, so that the workpiece will not rub the clamping plate 24 in the Y-axis fixed structure 21, and will not cause the side wall of the workpiece to be clamped to be damaged, so as to prevent the workpiece accuracy from being reduced, thereby improving the stability of the positioning system 2.

[0032] Although the provision of the protection structure 3 improves the stability of the positioning system 2, each time the positioning system 2 is used, the staff needs to push the slide plate 32 to reset the slide plate 32, which is very inconvenient. In order to solve this technical problem, the present embodiment provides a reset structure 4 for resetting the slide plate 32 on the side of the slide groove 30 away from the slide plate 32. The reset structure 4 includes a reset groove 40 provided on the side of the slide groove 30 away from the slide plate 32, a reset block 41 fixedly provided on the side of the slide bar 31 away from the slide plate 32, and a reset spring 42 provided on both sides of the reset groove 40 for pushing the reset block 41 to be centered in the reset groove 40. One end of the reset block 41 is fixedly connected to the slide bar 31, and the other end extends into the reset groove 40, and the reset block 4 1 is arranged in the middle of the slide bar 31, and the reset groove 40 is arranged along the length direction of the slide bar 30. One end of the reset spring 42 is fixedly connected to the side wall of the reset groove 40, and the other end abuts on one side of the reset block 41. When the slide plate 32 slides along the slide groove 30, it will compress one of the reset springs 42 on both sides of the reset groove 40. When the staff starts the extension of the driving electric cylinder 23 through the control panel 13, the clamping plate 24 will move away from the workpiece and no longer clamp the workpiece. At this time, the slide plate 32 loses the pressure on the workpiece, and the reset spring 42 will push the reset block 41 to move to the middle of the reset groove 40, so that the slide bar 31 drives the slide plate 32 to reset, so that the staff does not need to manually reset the slide plate 32, thereby improving the convenience of the positioning system 2.

[0033] Although the setting of the positioning system 2 reduces the manual intervention in the positioning of the workpiece origin, the positioning of the origin of the Z-axis still requires manual control of the machining spindle 10 to descend so that the tool can cut the upper surface of the workpiece. This leads to a certain deviation in the positioning of the origin. In addition, because the manual control of the machining spindle 10 to descend requires the tool to cut the workpiece before it can be determined whether the tool contacts the workpiece, after the Z-axis origin positioning is completed, the entire upper surface of the workpiece needs to be cut at the current position of the tool, which is very troublesome. In order to solve this technical problem, refer to Figure 5In this embodiment, a positioning device 5 for positioning the Z-axis origin is provided on one side of the machining spindle 10. The positioning device 5 includes a positioning electric cylinder 50 fixedly arranged on one side of the machining spindle 10, a positioning plate 51 installed on the output end of the positioning electric cylinder 50, and a pressure sensor 52 arranged on the bottom surface of the positioning plate 51. The pressure sensor 52 signal is connected to the control panel 13 and is used to start and stop the lifting and lowering of the machining spindle 10 through the control panel 13. The output end of the positioning electric cylinder 50 faces downward. Through the setting of the positioning device 5, when the staff locates the origin of the Z-axis, they only need to start the positioning electric cylinder 50 so that the output end of the positioning electric cylinder 50 extends downward until the pressure sensor 52 is coplanar with the tool end face. Then, there is no need to start the rotation of the machining spindle 10. It is only necessary to start the machining spindle 10 to descend. After descending until the pressure sensor 52 contacts the upper surface of the workpiece, the pressure sensor 52 sends a stop signal to the control panel 13, and the control panel 13 stops the descent of the machining spindle 10. At this time, the origin positioning of the Z-axis is completed, and there is no need to cut the upper surface of the workpiece, which further reduces the deviation of manual positioning, improves the machining accuracy, and reduces the defective rate.

[0034] Although the setting of the positioning device 5 further reduces the deviation of manual positioning, improves the processing accuracy, and reduces the defective rate, the positioning device 5 cannot be set too close to the processing spindle 10, otherwise it will affect the operation of the processing spindle 10. However, if it is set too far away from the processing spindle 10, the pressure sensor 52 of the positioning device 5 will not be able to contact the upper surface of the workpiece when the CNC milling machine processes a smaller workpiece. In order to solve this technical problem, in this embodiment, a positioning shell 53 is fixedly connected to the output end of the positioning electric cylinder 50, and a through hole penetrating the positioning shell 53 is opened on the side of the positioning shell 53 close to the processing spindle 10 and the bottom surface. The positioning plate 51 is slidably connected in the positioning shell 53 laterally, and the pressure sensor 52 of the positioning device 5 is unable to contact the upper surface of the workpiece. The sensor 52 extends out of the positioning housing 53, and the positioning plate 51 is installed on the output end of the positioning electric cylinder 50 through the positioning housing 53. Through the setting of the positioning housing 53, when the CNC milling machine processes a smaller workpiece, the staff can pull the positioning plate 51 to move toward the direction close to the machining spindle 10, so that the positioning plate 51 slides out of the positioning housing 53, so that the positioning plate 51 can be closer to the machining spindle 10, so that the pressure sensor 52 on the bottom of the positioning plate 51 can contact the upper surface of the smaller workpiece for positioning, and the setting of the positioning housing 53 can also allow the staff to pull the positioning plate 51 out of the positioning housing 53, so that the staff can easily replace and repair the pressure sensor 52.

[0035] In this embodiment, a fixing structure 6 for fixing the positioning block is provided on one side of the positioning shell 53, and the fixing structure 6 includes fixing holes 60 opened on the left and right sides of the positioning block and passing through the positioning block, and a fixing rod 61 arranged on the side of the positioning block close to the machining spindle 10 and passing through the positioning shell 53 and plugged into the positioning shell 53. Through the setting of the fixing structure 6, the positioning block is installed in the positioning shell 53 more stably.

[0036] Specific implementation process: first, place the workpiece at the intersection of the storage groove 22 of the Y-axis fixed structure 21 of the X-axis moving platform 12 and the storage groove 22 of the X-axis fixed structure 20, then start the X-axis moving platform 12, the Y-axis moving platform 11 and the processing spindle 10 to reset to the initial state through the control panel 13, and then start the driving electric cylinder 23, so that the output end of the driving electric cylinder 23 shrinks toward the center of the X-axis moving platform 12, and at the same time drives the clamping plate 24 to move toward the center of the X-axis moving platform 12, so that the clamping plates 24 in the X-axis fixed structure 20 and the Y-axis fixed structure 21 clamp the side walls of the workpiece respectively, and complete the X-axis and Y-axis origin positioning of the workpiece, and finally start the positioning electric cylinder 50, so that the output end of the positioning electric cylinder 50 extends downward until the pressure sensor 52 is coplanar with the tool end face; then start the processing spindle 10 to descend, and after descending until the pressure sensor 52 contacts the upper surface of the workpiece, the pressure sensor 52 sends a stop signal to the control panel 13, and the control panel 13 stops the descent of the processing spindle 10 to complete the Z-axis origin positioning of the workpiece.

[0037] The embodiments of this specific implementation method are all preferred embodiments of the present application, and are not intended to limit the protection scope of the application. Therefore, all equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
