Description

Technical Field

[0001] The utility model relates to the technical field of metal cutting numerical control processing, in particular to a lathe tool changing mechanism for a milling and turning compound machine tool. Background Art

[0002] Composite machining is one of the most popular machining processes in the world today. It is an advanced manufacturing technology for tool changing mechanisms on milling and turning compound machine tools. It combines several different machining processes on one machine tool. Composite machining is the most widely used and the most difficult. However, the tool changing mechanisms on existing compound machine tools are difficult to fix, which affects the workers' work efficiency. In addition, when changing tools, it is easy to have difficult tool changing angles, resulting in the disadvantage of difficult tool changing.

[0003] After searching, the Chinese patent with publication number CN220463087U discloses a tool changing mechanism for a lathe used in a milling-turning compound machine tool. This structure uses a clamp to use a slider to drive the movable block to move, so that the arc surface of the movable block contacts the outer wall of the tool barrel, and then the second bolt is screwed to make the outer plates at both ends of the elastic frame close to each other, and then reinforced with a second nut, so that the tool can be completely fixed in the tool barrel, thereby achieving the purpose of simple fixation. By setting a rocker, rotating the rocker can make the turntable rotate, thereby driving the tool disc to rotate, and thus driving the tool barrel to rotate, so that some positions that are difficult to move the tool can be moved to positions that are easy to replace, thereby achieving the purpose of easy tool change.

[0004] However, in actual use, this structure fixes the tool by fixing the extension plate provided on the surface of the elastic frame with bolts and nuts, and the bolts and nuts themselves are relatively small in size. Not only are they easily lost due to collisions caused by external factors during use, but they also require individual twisting and disassembly during installation and disassembly, which affects the installation efficiency of the tool.

[0021] See also Figures 1 to 5In an embodiment of the utility model, a tool changing mechanism for a lathe used in a milling-turning compound machine tool comprises a cutter disc and a plurality of fixed plates 6 fixedly mounted on the surface of the cutter disc 2 by screws, a cutter cylinder 14 is fixedly provided on the surfaces of the plurality of fixed plates 6, an adjustment component is provided on both sides of the cutter cylinder 14, and a positioning component is movably provided on both sides of the plurality of fixed plates 6, a connecting shaft 1 is provided with a fixed sleeve in the middle of the cutter disc 2, a mounting bracket 3 is provided on the outer rotating sleeve of the connecting shaft 1, a turntable 4 is fixedly provided on the top end of the connecting shaft 1 through the mounting bracket 3, and a rocker 5 is connected to the surface of the turntable 4.

[0022] In this embodiment: when encountering a position where the tool is difficult to change, rotating the rocker 5 can cause the turntable 4 to rotate, and then the connecting shaft 1 can be rotated, thereby driving the tool disc 2 to rotate, thereby driving the fixed plate 6 to rotate, thereby driving the tool cylinder 14 to rotate, so that some positions where the tool is difficult to change can be moved to positions where it is easy to change.

[0023] Please refer to Figure 3 、 Figure 5 The positioning component includes a plurality of limiting holes 7 symmetrically opened on the surface of the fixed plate 6. Two fixed cylinders 8 are movably provided on the surface of the fixed plate 6. Two fixed cylinders 8 are movably connected inside the two fixed cylinders 8. Two latches 19 are movably connected. One end of the two latches 19 is movably engaged with the limiting holes 7. A slide 18 is fixedly sleeved on the outside of the latches 19. The slide 18 is movably arranged inside the fixed cylinder 8. Two springs 17 are connected to the surface of the slide 18. Both springs 17 are sleeved on the outside of the latch 19. One end of the latch 19 is fixedly connected to the inner wall of the fixed cylinder 8. The other ends of the two latches 19 are fixedly provided with a handle 20.

[0024] In this embodiment: the elasticity of the spring 17 itself will push the slide plate 18 to drive the pin 19 to automatically insert into the limiting hole 7. By pulling the handle 20 upward, the pin 19 can be driven upward so that the pin 19 and the limiting hole 7 remain separated, thereby adjusting the relaxation state of the knife barrel 14, thereby achieving the function of automatically positioning the tool after installation without the need for screws.

[0025] Please refer to Figures 2-4The adjusting component includes a connecting block 13 movably arranged on both sides of the knife cylinder 14, and a slider 12 is fixedly provided on the surface of the two connecting blocks 13. Two telescopic rods 11 are provided on the surface of the slider 12. A cross plate 10 is commonly provided on the surface of the two telescopic rods 11, and a pull plate 9 is provided on the outer side of the cross plate 10; two first sliding rods 15 are fixedly provided on both sides of one of the cross plates 10, and one end of the two first sliding rods 15 passes through the other cross plate 10 and is fixedly connected to one of the pull plates 9; two second sliding rods 16 are symmetrically fixedly connected to the surface of the other cross plate 10, and the second sliding rod 16 is arranged on the outer side of the first sliding rod 15, and the second sliding rod 16 passes through one of the cross plates 10 and is fixedly connected to the surface of the other pull plate 9, and the first sliding rod 15 and the second sliding rod 16 are both slidably connected to the cross plate 10.

[0026] In this embodiment: when the two pulling plates 9 are pushed in two different directions, the first sliding rod 15 and the second sliding rod 16 can drive the cross plate 10 to move in two different directions, so that the connecting block 13 on the surface of the slider 12 can contact with the knife cylinder 14 to facilitate the adjustment of the relaxed state of the knife cylinder 14, thereby facilitating the replacement of the knife inside the knife cylinder 14, thereby achieving the function of easy knife replacement.

[0027] Please refer to Figure 3 The fixing tube 8 is fixedly arranged on the outer surface of the pulling plate 9.

[0028] In this embodiment, the fixing cylinder 8 is driven to move by the pulling plate 9, so that the tool can be conveniently positioned after being clamped.

[0029] Please refer to Figures 3 and 4 The surfaces of the first slide bar 15 and the second slide bar 16 are slidably connected to a support frame 21 , and the bottom of the support frame 21 is fixedly connected to the surface of the fixed plate 6 .

[0030] In this embodiment, the support frame 21 is slidably connected to the first slide bar 15 and the second slide bar 16 to improve the stability of the first slide bar 15 and the second slide bar 16 when moving.

[0031] Working principle of the present invention: When the device is in use, when encountering a position that is difficult to change the knife, rotating the rocker 5 can make the turntable 4 rotate, and then the connecting shaft 1 can be rotated, thereby driving the knife disc 2 to rotate, thereby driving the fixed plate 6 to rotate, thereby driving the knife cylinder 14 to rotate, so that some positions where the knife is difficult to change can be turned to a position where it is easy to change. Then the handle 20 is pulled upward, and the latch 19 can be driven to be pulled upward so that the latch 19 and the limit hole 7 remain separated. At the same time, the two pulling plates 9 are pushed inward, and the first slide bar 15 and the second slide bar 16 drive the cross plate 10 to move in the direction of the pulling plate 9. At this time, the knife cylinder 14 is in a relaxed state, so the knife inside the knife cylinder 14 can be changed, thereby achieving the purpose of easy knife changing.

[0032] After the tool change is completed, by pulling the two pull plates 9 outward, the horizontal plates 10 set at one end of the first slide bar 15 and the second slide bar 16 respectively drive the slider 12 to approach the extrusion knife cylinder 14. After adjusting to the appropriate distance, the handle 20 is released so that the elasticity of the spring 17 itself pushes the slide plate 18 to drive the pin 19 to be inserted into the limiting hole 7, thereby achieving the function of convenient tool positioning without the need for screws.

[0033] The above are only preferred specific implementation methods of the present invention, but the protection scope of the present invention is not limited to them. Any technician familiar with the technical field can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention within the technical scope disclosed by the present invention, and they should be covered by the protection scope of the present invention.
