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] Example 1
[0023] Please refer to Figure 1-5 As shown, this utility model provides a CNC machining equipment that facilitates tool replacement, including a frame 1 of the CNC equipment. A cylinder 2 for driving is installed on the top of the frame 1, a push rod 3 is installed at the bottom of the cylinder 2, a fixing plate 4 is installed at the bottom of the push rod 3, a threaded post 6 for fixing a tool 5 is installed at the bottom of the fixing plate 4, and an installation component for replacing the tool 5 is installed between the threaded post 6 and the tool 5.
[0024] The frame 1 can drive the cylinder 2 to move laterally and longitudinally. The cylinder 2 can drive the threaded column 6 at the bottom of the fixed plate 4 to move up and down through the push rod 3. According to the workpiece processing needs, the threaded column 6 can drive the tool 5 to process the workpiece. The mounting parts can replace or fix the tool 5 at the bottom of the threaded column 6, improving the convenience and stability of tool replacement.
[0025] Specifically, the mounting components include a fixing groove 7 at the bottom of the threaded post 6 for fixing the tool 5, six locking blocks 8 arranged in a circle are installed at one end of the threaded post 6, a fixing ring 9 for pressing the locking blocks 8 is fitted on the outside of the threaded post 6, a locking block 10 is connected to one side of the locking block 8, six locking grooves 11 arranged in a circle are opened on the outside of the tool 5, a groove 14 is opened at one end of the tool 5, a positioning block 15 is fixedly connected to the inside of the fixing groove 7, an anti-slip pad 16 is embedded in the inner wall of the locking block 8, a driven part 17 is installed on the other side of the locking block 8, the positioning block 15 is movably connected to the groove 14, and the fixing ring 9 is screwed to the threaded post 6.
[0026] The fixing groove 7 and the top of the cutter 5 are both hexagonal. Six locking blocks 8 are wrapped around the outside of the cutter 5 to increase the contact area. The cutter 5 is inserted into the fixing groove 7, and the positioning block 15 is embedded in the groove 14. The groove 14 and the positioning block 15 are both rectangular. The fixing ring 9 rotates on the outside of the threaded post 6. Then the fixing ring 9 squeezes and pushes the locking block 8. The driven part 17 on the outside of the locking block 8 is triangular. The anti-slip pad 16 on one side of the locking block 8 is in close contact with the outer wall of the cutter 5, so that the ends of the six locking blocks 8 are close to each other to clamp and fix the cutter 5. The locking block 10 on one side of the locking block 8 is embedded in the locking groove 11 on the outside of the cutter 5, which improves the convenience and stability of picking up and putting down the cutter 5 for replacement and installation.
