[0039] The present invention will be further described below with reference to specific embodiments:

[0040] like Figures 1-17 As shown, this utility model provides a CNC grinding machine for superhard cutting tools. The CNC grinding machine includes a robot arm 1, a machine bed 2, and a spindle seat 3 erected on one side of the machine bed. A first worktable slides on the machine bed, and a second worktable rotatably mounts on the first worktable. A clamping assembly 6 is mounted on the second worktable 5. In this embodiment, the first worktable is a slide table 4, and the second worktable is a cross-shaped worktable 5. The cross-shaped worktable 5 can adjust the lateral and longitudinal positions of the clamping assembly 6, and the workpiece is clamped on the clamping assembly 6. A first spindle 7 and a second spindle 8 are mounted on the spindle seat 3. A coarse grinding wheel 9 and a fine grinding wheel 10 are respectively mounted on the first spindle 7 and the second spindle 8. After coarse grinding, the workpiece is finely ground by the fine grinding wheel 10, eliminating the need for secondary clamping and resulting in high processing efficiency and high precision. Furthermore, in this invention, the first spindle 7 is mounted on a base 11, which is driven by a first drive mechanism to move up and down on the spindle seat 3 to adjust the vertical position of the first spindle 7. The first spindle 7 is also driven by a second drive mechanism to rotate on the base 11 to adjust its elevation angle. A visual measurement mechanism 12 for photographing and measuring the workpiece to be processed is provided above the clamping assembly 6. The robotic arm 1 is used to clamp the processed workpiece and hold the workpiece to be processed. This invention achieves full automation of workpiece loading, processing, and unloading, and the adjustable elevation angle of the first spindle 7 expands the processing range.

[0041] like Figure 1 , Figure 2 and Figure 3 As shown, the coarse grinding wheel 9, the fine grinding wheel 10, the vision measurement mechanism 12, and the fixture assembly 6 are located in an independent first space 13, while the robotic arm 1 is located in a second space 14. The first space 13 and the second space 14 are isolated and connected by a lifting plate 15, which is driven by a third drive mechanism. A material tray 16 is provided in the second space 14. The workpiece to be processed and the processed workpiece are placed on the material tray 16.

[0042] As can be seen from the above, the robotic arm 1 of this utility model is mounted on the bed 2, with a compact structure, no need for truss, and is also applicable to some spaces with small areas.

[0043] Specifically, such as Figure 3 As shown, the third drive mechanism includes a first guide rail 17 arranged vertically and a rodless cylinder 18. A lifting plate 15 is connected to the first guide rail 17 and also to the slider of the rodless cylinder 18. After processing is completed, the control system sends a signal to control the rodless cylinder 18 to open the lifting plate 15. One gripper of the robot arm 1 grasps the workpiece to be processed and extends into the first space 14. The other gripper of the robot arm 1 grasps the workpiece already processed on the fixture assembly 6, and then rotates the gripper to load the workpiece into the fixture assembly 6. After clamping, the robot arm 1 resets and transfers the processed workpiece into the corresponding position on the material tray 16. The lifting plate 15 also resets.

[0044] Since coolant is required during processing, the lifting plate 15 prevents liquid and debris in the first space 13 from entering the second space 14. The lifting plate 15 is typically made transparent, allowing operators to observe the robot arm 1 through it.

[0045] In order to further expand the processing range, the second spindle 8 of this utility model is driven by the fourth drive mechanism to rotate on the spindle seat 3 to adjust the elevation angle.

[0046] like Figure 6 and Figure 7 As shown, the fourth drive mechanism includes a fourth drive member 19, a fourth drive rod 20, a rotating seat 21 disposed at the front end of the second main shaft 8, a first fixed seat 22 disposed on the main shaft seat 3, and a second fixed seat 23. The rotating seat 21 is rotatably connected to the first fixed seat 22. A lifting seat 24 that moves vertically is disposed on the second fixed seat 23. The lifting seat 24 is connected to the end of the second main shaft 8 and is connected to the fourth drive rod 20. It should be noted that in this embodiment, the fourth drive member 19 is a motor, and the fourth drive rod 20 is a lead screw.

[0047] To ensure stable lifting, this utility model provides a second guide rail between the lifting seat 24 and the second fixed seat 23, and the lifting seat 24 is slidably connected to the second guide rail via a second slider.

[0048] When adjusting the elevation angle of the second spindle 8, the control system controls the fourth motor 19 to operate, driving the fourth lead screw 20 to rotate, which in turn drives the lifting seat 24 to rise and fall. Since the lifting seat 24 is connected to the end of the second spindle 8, the front end of the second spindle 8 will rotate on the first fixed seat 22 via the rotating seat 21, thereby achieving the purpose of adjusting the elevation angle of the second spindle 8. It should be noted that the axis of rotation of the rotating seat 21 is perpendicular to the axis of the second spindle 8.

[0049] Furthermore, the first driving mechanism of this utility model includes a first driving member and a first driving rod disposed on the spindle seat 3. The first driving member drives the first driving rod to move, and the first driving rod is connected to the base 11, causing the base 11 to move up and down on the spindle seat 3, thereby driving the first spindle 7 to adjust its vertical position. It should be noted that in this embodiment, the first driving member is a motor and the first driving rod is a lead screw.

[0050] To ensure smooth adjustment, this invention provides a third guide rail and a third slider between the main shaft seat 3 and the base 11.

[0051] like Figure 4 As shown, the second driving mechanism includes a second driving member rotatably mounted on the main shaft seat 3, a worm gear 25 and a turbine gear 26 mounted on the base 11, and a first arc-shaped guide rail 27 and a second arc-shaped guide rail 28 mounted on the first and second inner sidewalls of the base 11. The first main shaft 7 passes between the two inner sidewalls. The turbine gear 26 is rotatably mounted on the first main shaft 7, and a first slider is eccentrically connected to the turbine gear 26. The first slider can move along the first arc-shaped guide rail 27. A second slider is also mounted on the first main shaft 7, and the second slider can move along the second arc-shaped guide rail 28. In this embodiment, the second driving member is a motor.

[0052] like Figure 5 As shown, in order to buffer the first spindle 7 when adjusting its elevation angle, this invention provides a third driving member 29 along the vertical direction on the second inner sidewall. One end of the pull rope 30 is fixed to the base 11, and the other end is fixed to the first spindle 7. The pull rope 30 is wound around the top of the piston rod of the third driving member 29, and the third driving member 29 drives the pull rope 30 to always be in a taut state. In this embodiment, the third driving member 29 is preferably a cylinder.

[0053] When adjusting the elevation angle of the first spindle 7, the control system controls the second drive component to rotate, causing the worm gear 25 to rotate. The turbine 26 meshes with it and rotates. The first slider located on the turbine 26 moves along the first arc-shaped guide rail 26 as the turbine 26 moves. During this process, the third drive component 29 moves, causing the second slider to move along the second arc-shaped guide rail 28.

[0054] like Figure 1 , Figure 2 , Figure 8 and Figure 9 As shown, this utility model requires workpiece imaging and measurement during processing. The visual measurement mechanism 12 includes a monitoring system comprising a CCD camera and a lens barrel. The monitoring system is housed within a first housing 31, which has an opening 32 through which it can capture images of the workpiece. An opening / closing plate 33 is provided at the opening 32, and its movement is driven by a fifth driving component housed within a second housing 38. Specifically, the fifth driving component is a rotary cylinder or a motor. The first housing 31 is slidably mounted on a focusing mechanism 34, which adjusts the longitudinal and lateral positions of the housing using a longitudinal adjustment mechanism 35 and a lateral adjustment mechanism 36. The lateral adjustment mechanism 36 is mounted on the machine bed 2 via a bracket 37. The focusing mechanism 34 can be a lead screw drive mechanism. A lead screw nut is set on the first housing 31, and the lead screw nut is set on the lead screw. An adjusting nut is set at the lower end of the lead screw. The vertical position of the first housing 31 is adjusted manually by adjusting the adjusting nut, thereby adjusting the focal length of the monitoring system (such as a camera). The longitudinal adjustment mechanism 35 and the lateral adjustment mechanism 36 can adjust the corresponding positions of the visual measurement mechanism 12 according to the position of the workpiece.

[0055] To ensure smooth rotation, this invention provides an arc-shaped guide hole 39 on the opening and closing plate 33 and a guide rod on the second housing 38. The guide rod extends into the arc-shaped guide hole 39, and the arc length of the arc-shaped guide hole 39 limits the rotation stroke of the opening and closing plate 33.

[0056] The first housing 31 and the second housing 38 can prevent the coolant, debris and other contaminants in the first space 13 from affecting the monitoring system and drive components, and the visual measurement mechanism 12 can be built into the first space 13.

[0057] Furthermore, after grinding, metal shavings, abrasive particles, and oil accumulate on the grinding surface of the grinding wheel, affecting its grinding performance. Therefore, the grinding wheel must be cleaned. Figure 1 , Figure 2 , Figures 10-12As shown, the present invention has a drive motor on the coarse grinding wheel 9, and a cleaning wheel 41 is provided on the rotating shaft 40 of the drive motor. One end of the rotating shaft 40 extends out of the cleaning wheel 41 and is provided with a limiting member 42. A spring 43 is sleeved on the rotating shaft 40 between the cleaning wheel 41 and the limiting member 42, and the two ends of the spring 43 are respectively abutted on the cleaning wheel 41 and the limiting member 42. The cleaning wheel 41 is attached to the cleaning surface of the coarse grinding wheel 9.

[0058] Specifically, the cleaning grinding wheel 41 of this utility model is provided with a mounting joint at its center. The specific structure of the mounting joint is as follows: it includes a groove 44 on the inner side wall of the cleaning grinding wheel 41 and a protrusion 45 on the outer side wall of the cleaning grinding wheel 41. Two or more threaded holes are distributed circumferentially on the protrusion 45. The mounting joint is provided with a through hole 46 for the rotating shaft 40 to pass through.

[0059] The rotating shaft 40 is provided with a connector with a protrusion at one end. During installation, the cleaning grinding wheel 41 is inserted into the rotating shaft 40 and is connected to the protrusion through the groove 44. The cleaning grinding wheel 41 is fixed to the rotating shaft 40 by screwing it into the threaded hole on the protrusion 45.

[0060] This invention features a cleaning grinding wheel 41, which can clean the surface of the coarse grinding wheel 9 during the grinding process, ensuring that the grinding performance is not affected.

[0061] In addition, such as Figure 1 , Figure 2 and Figures 13-16 As shown, the clamping assembly 6 of this utility model includes a base 47 fixed on a cross worktable 4. A workpiece groove is provided at one end of the base 47, and a drive arm 48 is rotatably connected to the base 47. One end of the drive arm 48 is provided with a pressure plate that can press the workpiece in the workpiece groove, and the other end is provided with a sixth drive member 49 for driving the drive arm 48 to rotate. In this embodiment, the sixth drive member 49 is preferably a cylinder.

[0062] Furthermore, the pressure plate includes a pressure plate body 50, on which a pressing post 51 is provided. The pressing post 51 is detachably connected to the pressure plate body 50. The pressing post 51 includes a ball head 52, which protrudes from the bottom surface of the pressure plate body 50. The pressure plate body 50 also has a mounting part 53. The mounting part 53 is connected to one end of the drive arm 48 via a pin.

[0063] During clamping, the sixth drive member 49 drives one end of the drive arm 48 to move downward, so the pressure plate is lifted. The robot arm 1 transfers the workpiece to be processed into the workpiece slot. The sixth drive member 49 resets, so that the pressure plate presses on the upper surface of the workpiece to be processed, and the ball head 52 of the pressure plate is set in the center hole of the workpiece to be processed.

[0064] After repeated clamping, the ball head 52 may wear out, leading to defects such as inaccurate positioning. This can be resolved by replacing the pressure post 51, reducing operating costs. Furthermore, since the diameter of the center hole of the workpiece may vary, a ball head 52 of the appropriate size must be used; this can also be achieved by replacing the pressure post 51.

[0065] It should be noted that, as Figures 14-16 As shown, in one embodiment where the pressure post 51 and the pressure plate body 50 are detachably connected, the bottom surface of the pressure plate body 50 is provided with a threaded hole, and the pressure post 51 includes a screw 54 and a ball head 52 located at the bottom of the screw 54. The pressure post 51 is detachably connected to the pressure plate body 50 by screwing the screw 54 and the threaded hole.

[0066] like Figure 17 As shown, in another embodiment where the pressure post 51 and the pressure plate body 50 are detachably connected, the bottom surface of the pressure plate body 50 is provided with an mounting hole, the pressure post 51 includes a rod and a ball head 52 located at the bottom of the rod, and a set screw 55 is provided on the pressure plate body 50, one end of the set screw 55 abuts against the rod to fix the pressure post 51 to the pressure plate body 50.

[0067] The above embodiments are only one of the preferred embodiments of this utility model and are not intended to limit the scope of implementation of this utility model. Therefore, all equivalent changes made in accordance with the shape, structure and principle of this utility model should be covered within the protection scope of this utility model.
