[0001] This utility model relates to the field of CNC grinding machine technology, specifically to a support device for changing grinding wheels in CNC grinding machines. Background Technology

[0002] In grinding, in order to ensure the smooth operation of the grinding wheel, the grinding wheel is fixed by the grinding wheel chuck and then installed on the grinding machine spindle.

[0003] In the prior art, patent publication number CN202421010504.7 discloses a support device for changing grinding wheels on a CNC grinding machine, including a base, a tool changing body disposed on the base, a first support member supporting the tool body, an adjusting device for adjusting the up-and-down movement of the first support member, and a clamping plate for pressing the tool body; the tool changing body has a first sliding groove; the adjusting device is disposed in the first sliding groove; the first support member slides in the first sliding groove; the working end of the adjusting device abuts against the first support member; the clamping plate is detachably connected to the first support member;

[0004] The aforementioned support device for changing grinding wheels on CNC grinding machines has some problems in actual use. For example, when rotating the rotating rod to move the first support member up and down, thereby driving the tool body up and down, although the tool body can be adjusted up and down to support the grinding wheel, there is no good transmission structure. The vibration force generated by the grinding wheel during operation will affect the rotating member, causing it to rotate abnormally, which in turn leads to a poor support effect of the tool body on the support. Therefore, we propose a support device for changing grinding wheels on CNC grinding machines. Utility Model Content

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0022] Please see Figure 1-3 This embodiment provides a technical solution: a support device for changing grinding wheels on a CNC grinding machine, including a bracket 1 and a quick disassembly and assembly mechanism 4;

[0023] Support 1: The upper side is rotatably connected to the lower side docking frame 3, and the right side wall of support 1 is symmetrically fixed with triangular reinforcing plates at the front and back;

[0024] Quick-assembly / disassembly mechanism 4: It includes an upper docking frame 41, a mounting box 42, a worm gear 43, a rotating shaft 44, a worm wheel 45, a threaded rod 46, and a threaded cylinder 47. The upper docking frame 41 is located above the lower docking frame 3. The mounting box 42 is fixedly connected to the upper side of the upper docking frame 41. The lower side wall of the mounting box 42 is symmetrically rotatably connected to the rotating shaft 44. The lower ends of the two rotating shafts 44 are fixedly connected to the threaded rods 46, and the upper ends of the two rotating shafts 44 are fixedly connected to the worm wheels 45. The rear sides of the left and right sides of the mounting box 42 are rotatably connected to the worm gears 43, respectively. The two worm gears 43 are fixedly connected to each other and mesh with the longitudinally adjacent worm wheels 45. The upper surface of the lower docking frame 3 is symmetrically fixedly connected to the threaded cylinders. 47. The quick disassembly and assembly mechanism 4 also includes a plug rod 48 and a plug sleeve 49. The plug rod 48 is symmetrically fixed to the lower surface of the upper docking frame 41. The plug sleeve 49 is symmetrically fixed to the upper surface of the lower docking frame 3. A torsion valve 5 is provided at the left end of the worm gear 43 on the left side. An inner sleeve 6 is fixedly connected to the middle of the upper surface of the lower docking frame 3. An outer sleeve 7 is fixedly connected to the middle of the lower surface of the upper docking frame 41. A slot 8 is provided on the upper surface of the lower docking frame 3. A grinding wheel 2 is fixedly fitted on the outer arc surface of the outer sleeve 7. Guide posts 9 are fixedly connected to the lower ends of the two threaded rods 46 respectively. The diameter of the guide posts 9 is smaller than the diameter of the threaded rods 46. When the CNC grinding machine is working and it is necessary to replace the grinding wheel 2, the CNC grinding machine can be adjusted. When the CNC grinding machine is powered off, it can be manually adjusted. Twisting the valve 5 causes the two worm gears 43 to rotate synchronously, which in turn drives the two rotating shafts 44 to rotate synchronously via the worm wheel 45, which in turn drives the two threaded rods 46 to rotate synchronously, thus moving the upper docking frame 41 upward until the threaded rods 46 and the threaded cylinder 47 lose their threaded connection. At this point, the upper docking frame 41 can be manually removed, and the grinding wheel 2 that needs to be replaced can be removed. Then, take the new grinding wheel 2 and insert the mounting port in the middle of the grinding wheel 2 into the outer arc surfaces of the two rotating shafts 44 and the two insert rods 48 in sequence. At this point, the upper side of the upper docking frame 41 can be manually supported, and with the primary guidance of the insert cylinder 49 and the insert rod 48, the insert rod 48 can be inserted into the interior of the insert cylinder 49 until the guide post 9 is inserted into the threaded cylinder 47. Inside the machine, the installer can use their other hand to reverse the twist valve 5, causing the two worm gears 43 to rotate synchronously in the opposite direction. This, in turn, drives the two rotating shafts 44 to rotate synchronously in the opposite direction via the worm wheel 45, which in turn drives the two threaded rods 46 to rotate synchronously in the opposite direction until the threaded rods 46 and the threaded cylinder 47 are reconnected. Then, the twist valve 5 is reversed again, causing the upper docking bracket 41 to slowly approach the lower docking bracket 3 until the outer sleeve 7 fits onto the inner sleeve 6. The lower side of the outer sleeve 7 is inserted into the slot 8. At this point, the inner arc surface of the grinding wheel 2 fits onto the outer arc surface of the outer sleeve 7, the upper surface of the grinding wheel 2 contacts the lower surface of the upper docking bracket 41, and the lower surface of the grinding wheel 2 contacts the upper surface of the lower docking bracket 3, tightly clamping the grinding wheel 2.Complete the replacement of grinding wheel 2 in the CNC grinding machine.

[0025] The working principle of the support device for changing grinding wheels on a CNC grinding machine provided by this utility model is as follows: When the CNC grinding machine is working and it is necessary to replace the grinding wheel 2, the CNC grinding machine can be adjusted and the power is turned off. At this time, the torsion valve 5 can be manually turned, which will drive the two worm gears 43 to rotate synchronously. This will drive the two rotating shafts 44 to rotate synchronously through the worm wheel 45, which will drive the two threaded rods 46 to rotate synchronously. This will drive the upper docking frame 41 to move upward until the threaded rods 46 and the threaded cylinder 47 lose their threaded connection. At this time, the upper docking frame 41 can be manually removed, and the grinding wheel 2 that needs to be replaced can be removed. Then, the new grinding wheel 2 can be taken out, and the mounting port in the middle of the grinding wheel 2 can be inserted sequentially into the outer arc surface of the two rotating shafts 44 and the outer arc surface of the two insert rods 48. At this time, the upper side of the upper docking frame 41 can be manually supported, and the insert rod 48 can guide the insertion rod 49 to insert the new grinding wheel 2 into the new grinding wheel 2. The rod 48 is inserted into the inside of the insert 49 until the guide post 9 is inserted into the inside of the threaded cylinder 47. At this time, the installer can turn the torsion valve 5 in the opposite direction with his other hand, which will drive the two worm gears 43 to rotate in the opposite direction synchronously. This will drive the two rotating shafts 44 to rotate in the opposite direction synchronously through the worm wheel 45, which will drive the two threaded rods 46 to rotate in the opposite direction synchronously until the threaded rods 46 and the threaded cylinder 47 are restored to the threaded connection. At this time, continue to turn the torsion valve 5 in the opposite direction, which will drive the upper docking frame 41 to slowly approach the lower docking frame 3 until the outer sleeve 7 fits into the inner sleeve 6. The lower side of the outer sleeve 7 is inserted into the slot 8. At this time, the inner arc surface of the grinding wheel 2 fits into the outer arc surface of the outer sleeve 7. The upper surface of the grinding wheel 2 contacts the lower surface of the upper docking frame 41, and the lower surface of the grinding wheel 2 contacts the upper surface of the lower docking frame 3, and the grinding wheel 2 is tightly clamped, thus completing the replacement of the grinding wheel 2 in the CNC grinding machine.
