When the tool needs to be changed, the tool changing platform can be folded as a whole to the inside of the lathe, and then driven by the first servo motor so that its output shaft drives the threaded rod to rotate. Due to the limiting of the limiting rod, the movable screw block can drive the tool changing platform and other components to accurately adjust the position, thereby improving the accuracy of the tool changing device.

[0020] See also Figure 4-8, a ramp 38 is fixedly installed on one side of the outer surface of the tool change block 32, a side plate 33 is fixedly installed on the other side of the tool change block 32, and a collection frame 5 is fixedly installed on one side of the top of the tool change platform 2. The tool magazine structure 4 includes a mounting column 41, which is fixedly connected to the tool change platform 2, and a cutter disc 42 is rotatably installed on the top of the mounting column 41, and a clamping groove 43 is provided inside the cutter disc 42, and a circle of teeth is provided inside the clamping groove 43. Eight groups of grabbing grooves 44 are provided on one side below the cutter disc 42, and elastic buckles 45 are fixedly installed in the middle position of the eight groups of grabbing grooves 44, and diamond cutter heads 46 are clamped inside the eight groups of elastic buckles 45.

[0021] When removing the knife, after the damaged diamond cutter head 46 is removed by the electric gripper 37, the sliding block 31 drives the tool changing block 32 to reset to the initial position. After the electric gripper 37 releases the replaced diamond cutter head 46, the first electric push rod 35 drives the electric cylinder 36 to move downward. At this time, due to the inclined surface design of the inclined plate 38, when the inclined plate 38 contacts the diamond cutter head 46, the diamond cutter head 46 can be rolled into the collection frame 5 through the side plate 33 along the inclined surface of the inclined plate 38 for collection. The second servo motor 23 is driven to drive the gear 24 to rotate through its output shaft. Since the gear 24 is meshed with the internal teeth of the clamping groove 43, the cutter disc 42 can be rotated to turn another diamond cutter head 46 to the tool changing position.

[0022] See also Figure 1-2 The movable structure 1 includes a first fixed ring 101 and two limit rods 104. The first fixed ring 101 can be fixed on the outside of the lathe. The two limit rods 104 can be fixed on the outside of the lathe. A first servo motor 102 is fixedly installed inside the first fixed ring 101. A threaded rod 103 is fixedly installed on one end of the output shaft of the first servo motor 102, and the threaded rod 103 is rotatably connected to the outside of the lathe. A moving screw block 105 is threadedly installed on the outer surface of the threaded rod 103, and the moving screw block 105 is slidably connected to the two limit rods 104. A fixed rod 106 is fixedly installed on the top of the moving screw block 105, and the fixed rod 106 is rotatably connected to the sleeve 21.

[0023] When the lathe is in normal use, the sleeve 21 is sleeved on the outside of the fixed rod 106. At this time, the tool changing platform 2 is folded as a whole to the outside of the lathe. When the tool needs to be changed, the tool changing platform 2 can be folded as a whole to the inside of the lathe, and then driven by the first servo motor 102, so that its output shaft drives the threaded rod 103 to rotate. Due to the limitation of the limiting rod 104, the movable screw block 105 can drive the tool changing platform 2 and other components to accurately adjust the position.

[0024] Working principle: when a tool changing device of a diamond lathe is used, first when the lathe is in normal use, the sleeve 21 is sleeved on the outside of the fixed rod 106, and the tool changing platform 2 is folded to the outside of the lathe as a whole. When the tool needs to be changed, the tool changing platform 2 can be folded to the inside of the lathe as a whole, and then driven by the first servo motor 102, the output shaft drives the threaded rod 103 to rotate. Due to the limit of the limit rod 104, the movable screw block 105 can drive the tool changing platform 2 and other components to accurately adjust the position. During the tool changing process, The tool changing table 2 is turned over to the inside of the lathe, and then the telescopic rod is driven by the first electric push rod 35 to drive the electric cylinder 36 to move upward, and then the electric cylinder 36 is started to make the two sets of electric clamps 37 clamp one of the diamond cutter heads 46, and then the first electric push rod 35 is reset to make the diamond cutter head 46 drop to a position parallel to the cutter head, and then the second electric push rods 310 on both sides are driven at the same time to make their output shafts push the connecting block 311. Since the connecting block 311 is hinged to the hinge rod 313 through the rotating rod 312, When the connecting block 311 is pushed, the hinged rods 313 on both sides can be folded around the lower half. Since the upper end of the hinged rod 313 is slidably connected to the first slide groove 34, when the hinged rod 313 is folded, the tool changing block 32 and the sliding block 31 can be driven to move forward in the second slide groove 7, thereby inserting the diamond cutter head 46 into the cutter hole. At the same time, the second servo motor 23 is driven to drive the output shaft of the second servo motor 23 to drive the gear 24 to rotate. Since the gear 24 is engaged with the internal teeth of the clamping groove 43, the cutter head 42 can be rotated to move the other end. The diamond cutter head 46 is turned to the tool changing position to wait for the next tool change. When taking the tool, the damaged diamond cutter head 46 is removed by the electric clamp 37, and the sliding block 31 drives the tool changing block 32 to reset to the initial position. After the electric clamp 37 releases the replaced diamond cutter head 46, the first electric push rod 35 drives the electric cylinder 36 to move downward. At this time, due to the inclined surface design of the inclined plate 38, when the inclined plate 38 contacts the diamond cutter head 46, the diamond cutter head 46 can roll along the inclined surface of the inclined plate 38 through the side plate 33 into the collection frame 5 for collection.
