Description

Technical Field

[0001] This utility model belongs to the technical field of machine tool testing devices, specifically relating to a machine tool slant axis CNC precision testing device. Background Technology

[0002] Currently, the Renishaw XL80 is used for CNC accuracy testing of CNC machine tools. However, the Renishaw XL80 has slow light adjustment efficiency when testing machine tools with slanted axes. Existing machine tools typically require slanted axis testing to detect positioning and repeatability errors, supporting high-precision machining. Since the slanted axis is a non-orthogonal axis, the laser beam path needs to be adjusted during testing to ensure the incident and reflected rays coincide. Then, the rotating mirror and fine-tuning laser source are adjusted during machine tool movement. This makes testing with slanted axes complex and requires highly skilled operators. The machine tool movement position needs to be verified multiple times to find the appropriate position.

[0003] During the testing process, the laser beam needs to be aligned so that the incident and reflected beams coincide. Then, the machine tool is moved back and forth to adjust the laser source. The machine tool moves back and forth to verify the data and see if the beam is consistent with the angle of the machine tool's oblique axis. This process requires a long time to verify in order to find a suitable position so that the incident and reflected beams coincide and the angle of the machine tool's oblique axis is consistent. Moreover, the machine tool needs to run the program once for each verification, which is time-consuming and inefficient.

[0004] Based on this, a machine tool slant axis CNC precision testing device is proposed. Utility Model Content

[0013] To make the technical problem to be solved, the technical solution, and the beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the described embodiments are only a part of the embodiments of this application, not all of them. The specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0014] It should be further explained that the accompanying drawings and embodiments of this utility model mainly describe the concept of this utility model. Based on this concept, some specific forms and settings of connection relationships, positional relationships, power mechanisms, power supply systems, hydraulic systems and control systems may not be fully described. However, under the premise that those skilled in the art understand the concept of this utility model, they can implement the above-mentioned specific forms and settings in a well-known manner.

[0015] When a component is referred to as being "fixed to" or "set on" another component, it can be directly on or indirectly on that other component. When a component is referred to as being "connected to" another component, it can be directly connected to or indirectly connected to that other component.

[0016] The directional terms "inner" and "outer" refer to the inner and outer contours of each component. The terms "length," "width," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," or "outer" indicate the orientation or positional relationship 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.

[0017] For ease of description, spatial relative terms such as "above," "over," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "above" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways, and the spatial relative descriptions used herein will be interpreted accordingly.

[0018] The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "multiple" means two or more, and "several" means one or more, unless otherwise explicitly specified.

[0019] like Figure 1-3 As shown, this utility model provides a technical solution: a machine tool slant axis CNC precision testing device, including a magnetic base 2, a reflector 4, a rotating mirror 5, a refracting mirror 6, and a laser source 7. The magnetic base 2 is magnetically connected to the machine tool rotation center 11 of the machine tool 1. In this embodiment, a level is also included. The level is installed on the magnetic base 2 and the leveling operation of the magnetic base 2 is completed by the level. It also includes a target ring marker, which is mounted on the magnetic base 2 or the extension rod 3; The reflector 4 and the rotating mirror 5 are mounted on the extension rod 3 of the magnetic base 2. The optical lenses inside the reflector 4 and the rotating mirror 5 are rotatably connected to the connecting frame. The detection optical path can be adjusted by rotating the angle of the optical lenses. The refracting mirror 6 is mounted on the machine tool slant axis 12 of the machine tool 1. The laser source 7 is used to emit laser light. The laser light forms the detection optical path through the cooperation of the rotating mirror 5, the reflector 4 and the refracting mirror 6.

[0020] As one possible implementation method in this embodiment, the above-described machine tool slant axis CNC accuracy detection method includes the following steps: S1. Connect the magnetic base 2, extension rod 3, reflector 4, rotary mirror 5 and refractor 6 to the machine tool rotation center 11 or machine tool slant axis 12 of the machine tool 1 respectively. S2. Adjust the laser source 7 to a horizontal position, adjust the optical lens angle of the reflector 4, and then adjust the rotating mirror 5 to make the incident light generated by the laser source 7 undergo total internal reflection, so that the laser point hits the target ring mark on the magnetic base 2. S3. Adjust the rotary mirror 5 to make the laser point hit the center position of the target ring mark, and move the machine tool slant axis 12 to the preset machine tool zero point using the lead screw transmission mechanism in the machine tool 1. Adjust the angle of the rotary mirror 5. During the process of the machine tool slant axis 12 moving between the preset machine tool zero point and the preset machine tool farthest point, pay attention to the direction of the laser point's movement. If the laser point moves horizontally in the target ring marking, adjust the magnetic base 2 to keep it horizontal so that the laser point does not move horizontally. Observe the vertical movement of the laser point when it does not move horizontally. Specifically, when the laser point moves upward, the light beam is too high, so the rotating mirror lowers the light beam; when the laser point moves downward, the light beam is too low, so the rotating mirror raises the light beam. S4. Then, position the laser point slightly below the target ring mark, and move the machine tool slant axis 12 between the preset machine tool zero point and the preset machine tool farthest point. Fine-tune the reflector 4 and the rotary mirror 5 to keep the laser point in the same position during the movement of the machine tool slant axis 12. S5. Reinstall the reflector 4 on the extension rod 3, and fine-tune the reflector 4 and the rotating mirror 5 to make the incident light and the reflected light coincide. This completes the adjustment of the detection optical path and allows for subsequent CNC accuracy detection and compensation. This not only eliminates the problems caused by the accuracy detection of the machine tool slant axis 12, but also accurately and quickly determines the coincidence position of the incident light and the reflected light, making the incident light and the reflected light coincide. This reduces the time for manual adjustment and effectively improves the accuracy detection efficiency of the slant axis.

[0021] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations.
