Description

Technical Field

[0001] This utility model relates to the field of tool setting instrument detection technology, specifically a tool setting instrument motion drive mechanism. Background Technology

[0002] CNC machining centers have the ability to automatically change machining tools. By using tools of different purposes in the tool magazine, the machining tools on the spindle can be changed in a single setup via an automatic tool changer, thus achieving multi-purpose machining. However, during CNC machining, after a period of use, tool wear affects machining accuracy, requiring a significant amount of time for tool replacement and measurement calibration. Tool adjustment and measurement, in particular, are time-consuming and labor-intensive. If the tool face is machined away or a tool breaks during machining, resetting the tool is troublesome and inaccurate. Therefore, tool setting devices have emerged to address this issue.

[0003] A tool setter is a precision measuring tool used on CNC machine tools to determine the position, size, and geometric parameters of the tool relative to the workpiece, thereby improving machining accuracy and efficiency.

[0004] When performing production inspection, tool setters require a drive device for displacement driving. This drives the tool setter to move through a motion mechanism, causing it to actively contact the external workpiece to perform tool setting accuracy testing and ensure the quality of the tool setter product before it leaves the factory. However, traditional tool setter drive structures have poor axial displacement driving effect, insufficient axial linkage, and low overall structural flexibility, which limits their use and reduces the driving and testing effect of the tool setter. Therefore, this utility model proposes a tool setter motion drive mechanism. Utility Model Content

[0006] To achieve the above objectives, this utility model provides the following technical solution: a motion drive mechanism for a tool setting device, comprising an X-axis plate, on both sides of the outer surface of the X-axis plate being fixedly mounted with primary bearing seats, an X-axis lead screw being rotatably connected between the two primary bearing seats, one end of the X-axis lead screw being fixedly connected to the output shaft of a primary motor, the primary motor being fixedly mounted on the outer wall of one end of the X-axis plate by bolts, an X-axis slide being sleeved on the X-axis lead screw, the X-axis slide being threadedly connected to the X-axis lead screw, a Y-axis plate being fixedly mounted on the outer surface of the X-axis slide, secondary bearing seats being fixedly mounted on the upper and lower outer walls of the Y-axis plate, a Y-axis lead screw being rotatably connected between the two secondary bearing seats, the top end of the Y-axis lead screw being fixedly connected to the output shaft of a secondary motor, a Y-axis slide being threadedly connected to the Y-axis lead screw, an R-axis motor being fixedly mounted on the front outer wall of the Y-axis slide, and a mounting base being fixedly mounted on the top end of the output shaft of the R-axis motor.

[0007] Preferably, both the primary motor and the secondary motor are servo motors.

[0008] Preferably, the Y-axis plate and the X-axis plate are arranged perpendicular to each other.

[0010] Preferably, two secondary linear guides are fixedly installed on both sides of the outer surface of the Y-axis plate, and the back sides of the Y-axis slide are limited and slidably connected to the secondary linear guides.

[0011] Preferably, the outer surface of the X-axis plate is provided with fixing holes at the four corners for fixing the mechanism assembly, and fixing bolts with matching hole diameters are provided in the fixing holes.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This invention allows the tool setting surface of the tool setting instrument to be freely adjusted in the up, down, left, right, or tilt direction, effectively changing the orientation of the tool setting surface. In actual testing, it can be used for tool setting testing on external testing structures in different directions, satisfying tool setting testing work from top to bottom, bottom to top, left to right, right to left, or tilt direction. It has the practical effect of multi-directional testing, meeting the diverse testing needs of the tool setting instrument, making it more practical and with greater structural flexibility.

[0014] Furthermore, the motion drive mechanism of this utility model can drive the tool setter to perform three-axis simultaneous displacement along the X, Y, and R axes, exhibiting practical multi-axis linkage characteristics. This effectively improves the axial displacement driving performance of traditional tool setter detection drive structures. Simultaneously, the power drive structures of the X, Y, and R axes are independent of each other, allowing for single-axis displacement drive as well as dual-axis or three-axis coordinated linkage. This effectively enhances the linkage and coordination between axes, providing diverse usage characteristics of single-axis drive or multi-axis linkage. It can meet the production requirements and usage needs under different detection conditions, offering enhanced usability, effectively reducing structural limitations, making the use and detection of the drive structure more flexible, and improving the overall structural performance.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] In the description of this utility model, it should be noted that the terms "upper," "lower," "inner," "outer," "front end," "rear end," "both ends," "one end," and "the other end," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used 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. In addition, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0022] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," and "connected," etc., should be interpreted broadly. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0023] Please see Figure 1-4 An embodiment of this utility model provides a tool setting device motion drive mechanism, including an X-axis plate 1. Primary bearing seats 2 are fixedly installed on both sides of the outer surface of the X-axis plate 1. An X-axis lead screw 3 is rotatably connected between the two primary bearing seats 2. One end of the X-axis lead screw 3 is fixedly connected to the output shaft of a primary motor 4. The primary motor 4 is fixedly installed on the outer wall of one end of the X-axis plate 1 by bolts. An X-axis slide 5 is sleeved on the X-axis lead screw 3. The X-axis slide 5 and the X-axis lead screw 3 are connected by a threaded transmission.

[0024] In order to ensure the free movement effect of the motion drive structure of this utility model in the X-axis direction, the primary motor 4 is designed to rotate. When the primary motor 4 rotates in both directions, it will drive the X-axis lead screw 3 to rotate in both directions in a synchronous manner through the output shaft. When the X-axis lead screw 3 rotates, the X-axis slide 5 connected to it by the thread can move left and right along the X-axis direction of the X-axis lead screw 3. In this way, the free movement effect of the motion drive structure of this utility model in the X-axis direction can be ensured through the X-axis thread transmission effect.

[0025] Furthermore, to ensure free movement along the Y-axis, a Y-axis plate 6 is fixedly mounted on the outer surface of the X-axis slide 5, as shown in the attached instruction manual. Figure 1 As shown, the Y-axis plate 6 and the X-axis plate 1 are set perpendicular to each other;

[0026] Two secondary bearing seats 7 are fixedly installed on the outer walls of the upper and lower ends of the Y-axis plate 6. A Y-axis lead screw 8 is rotatably connected between the two secondary bearing seats 7. The output shaft of the secondary motor 12 is fixedly connected to the top of the Y-axis lead screw 8. A Y-axis slide 9 is threadedly connected to the Y-axis lead screw 8. An R-axis motor 13 is fixedly installed on the outer wall of the front of the Y-axis slide 9. A mounting seat 14 is fixedly installed at the top of the output shaft of the R-axis motor 13.

[0027] Based on the above structural description, the motion drive mechanism of this utility model, in practice, allows the mounting base 14 to house the tool setting device that requires quality inspection. The tool setting device is mounted on the mounting base 14. The R-axis motor 13 drives the mounting base 14 to rotate 360°. In actual use, the rotation of the mounting base 14 synchronously drives the tool setting device mounted on it to rotate 360°, thus achieving the practical effect of R-axis rotation of the tool setting device. During actual inspection, the tool setting device is adjusted... The instrument rotates its posture, allowing it to dynamically change the detection surface. This means the tool setting surface can be freely adjusted in the up, down, left, right, or tilt direction, effectively changing its orientation. In actual use, it can be applied to external detection structures in different directions for tool setting. It can meet the needs of tool setting work from top to bottom, bottom to top, left to right, right to left, or tilt, providing multi-directional detection capabilities and meeting the diverse detection needs of the tool setting instrument. It is more practical and has a more flexible structure.

[0028] Meanwhile, the two-stage motor 12 in this invention drives the Y-axis lead screw 8 to rotate synchronously in both directions via its output shaft. When the Y-axis lead screw 8 rotates, the Y-axis slide 9, which is threaded onto it, can move up and down along the Y-axis lead screw 8. This up-and-down movement of the Y-axis slide 9 drives the tool setter on the mounting base 14 to move up and down, satisfying the requirement for free movement of the tool setter in the Y-axis direction. By using it in conjunction with the X-axis motion structure, the motion drive mechanism of this invention can drive the tool setter to move simultaneously along the X, Y, and R axes, achieving multi-axis linkage. Based on its practical application characteristics, this design effectively improves the axial displacement driving performance of the traditional tool setting device's detection drive structure. Furthermore, the power drive structures of the X, Y, and R axes are independent of each other, allowing for single-axis displacement drive as well as dual-axis or tri-axis coordinated linkage. This effectively enhances the linkage and coordination between axes, providing diverse application characteristics of single-axis drive or multi-axis linkage. It can meet the production requirements and usage needs under different detection conditions, offering greater usability, effectively reducing structural limitations, making the use and detection of the drive structure more flexible, and improving the overall structural performance.

[0029] In this embodiment, to facilitate PLC control of the motors, both the primary motor 4 and the secondary motor 12 are servo motors. The control of servo motors is a mature and simple publicly available technology in the PLC field, and this specification will not elaborate further on its detailed control principles.

[0030] In this embodiment, in order to improve the displacement guidance of the X-axis slide 5 and the Y-axis slide 9 and ensure that the two slides have a linear displacement effect, a primary linear guide rail 10 is fixedly installed on both sides of the outer surface of the X-axis plate 1, and the back sides of the X-axis slide 5 are limited and slidably connected to the primary linear guide rail 10.

[0031] Furthermore, two secondary linear guide rails 11 are fixedly installed on both sides of the outer surface of the Y-axis plate 6, and the back sides of the Y-axis slide block 9 are limited and slidably connected to the secondary linear guide rails 11.

[0032] By cooperating with the two linear guides and the slide block, the displacement guidance of the X-axis slide block 5 and the Y-axis slide block 9 can be guaranteed.

[0033] In this embodiment, in order to assemble and install the motion drive mechanism of the present invention, fixing holes for fixing the mechanism assembly are provided at the four corners of the outer surface of the X-axis plate 1. Fixing bolts with matching hole diameters are provided in the fixing holes, so that the mechanism assembly of the present invention can be installed on an externally adapted machine through the fixing holes and fixing bolts.

[0034] Working principle: When the motion drive structure of this utility model is in use, it can be installed on an externally adapted testing machine through the fixing holes at the four corners of the X-axis plate 1, thereby ensuring the normal use of this utility model.

[0035] In practical use, the motion drive mechanism of this utility model allows for the mounting of a tool setting device requiring quality inspection via a mounting base 14. The tool setting device is mounted on the mounting base 14. The R-axis motor 13 drives the mounting base 14 to rotate 360°. In actual use, the rotation of the mounting base 14 synchronously drives the mounted tool setting device to rotate 360°, thus achieving the practical effect of R-axis rotation of the tool setting device. During actual inspection, the tool setting device's posture is adjusted by rotation... The rotating mechanism allows for dynamic changes in the detection surface, enabling free adjustment of the tool setting surface in the up, down, left, right, or tilt directions. This effectively changes the orientation of the tool setting surface, making it suitable for tool setting tests on external detection structures in different directions. It can meet the requirements for tool setting tests from top to bottom, bottom to top, left to right, right to left, or tilt, providing multi-directional detection capabilities and satisfying diverse testing needs. This enhances its practicality and increases the flexibility of its structure.

[0036] This utility model can be rotated by a primary motor 4. When the primary motor 4 rotates in both directions, it will synchronously drive the X-axis lead screw 3 to rotate in both directions through the output shaft. When the X-axis lead screw 3 rotates, the X-axis slide 5 connected to it by a thread can move left and right along the X-axis direction of the X-axis lead screw 3. In this way, the X-axis thread transmission effect can ensure the free movement effect of the motion drive structure of this utility model in the X-axis direction.

[0037] Meanwhile, the two-stage motor 12 of this utility model can drive the Y-axis lead screw 8 to rotate synchronously in both directions through its output shaft. When the Y-axis lead screw 8 is rotating, the Y-axis slide 9 connected to it by threads can move up and down along the Y-axis lead screw 8. In this way, the up and down displacement of the Y-axis slide 9 can drive the tool setter on the mounting base 14 to move up and down, so as to satisfy the free movement effect of the tool setter in the Y-axis direction.

[0038] By using the X-axis motion structure, the motion drive mechanism of this invention can drive the tool setter to perform simultaneous three-axis displacement along the X, Y, and R axes, exhibiting multi-axis linkage characteristics. This effectively improves the axial displacement driving performance of traditional tool setter detection drive structures. Furthermore, the power drive structures of the X, Y, and R axes are independent of each other, allowing for single-axis displacement drive as well as dual-axis or three-axis coordinated linkage. This effectively enhances the linkage and coordination between axes, providing diverse usage characteristics of single-axis drive or multi-axis linkage. It can meet the production requirements and usage needs under different detection conditions, offering greater usability, effectively reducing structural limitations, making the use and detection of the drive structure more flexible, and improving the overall structural performance.

[0039] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
