Each station can rotate independently, that is, the tool rotating disk 3 can rotate above the main rotating disk 2 to facilitate the mating of the mounting keyway of the tool holder with the spindle limiting positioning key, and facilitate the connection between the tool holder and the spindle.

[0023] A tool rotating disk bearing 17 corresponding to the tool rotating disk 3 is provided in the middle of the tool rotating disk base 16. The bottom of the tool rotating disk 3 is fixedly connected with a sub-tool disk slider 29. The sub-tool disk slider 29 is slidably connected with the bushing of the tool rotating disk bearing 17. A lifting cylinder 15 is installed at the bottom of the tool rotating disk base 16. The output end of the lifting cylinder 15 contacts the bottom of the sub-tool disk slider 29. During use, when the machine tool spindle moves to a fixed position above the tool magazine, that is, above the main rotating disk 2, the tool rotating disk 3 corresponding to the bottom of the spindle has the function of lifting the tool. By starting the lifting cylinder 15, the sub-tool disk slider 29 at the bottom of the tool rotating disk 3 can be pushed upward, thereby pushing up the tool rotating disk 3. After the tool is lifted, the spindle can tighten the tool to complete the connection.

[0024] A positioning seat 19 is installed on one side of the top of the basic base 1 close to the main rotating disk base 28.

[0025] A manipulator clamping cylinder 20 is installed on the top of the rotating shaft base 30, a connecting rod 23 is provided in the middle of the rotating shaft base 30, and the output end of the manipulator clamping cylinder 20 is connected to the connecting rod 23, the bottom of the rotating shaft base 30 is rotatably connected to the clamp arm 26 through the rotating shaft 25, one end of the connecting rod 23 is connected to the clamp arm 26 through the connecting pin 24, the bottom of the clamp arm 26 is connected to the clamp seat 27, and rotating wheels 7 are installed on both sides of the clamp seat 27. A chain is provided on the surface of the rotating gear 21, and the rotating gear 21 is connected to the guide slide 1 through the chain. 1 transmission connection, a plurality of wire wheels 13 are installed on the surface of the manipulator base 10, and a wire rope 12 is provided on the surface of the wire wheel 13. A lifting ring 14 is installed on the top of the manipulator position correction seat 5, and the wire rope 12 is wound and connected with the lifting ring 14. After the tool whose blade needs to be replaced rotates to the fixed tool changing position, the manipulator 8 is released and falls to the tool position. The manipulator 8 clamps the tool, and then lifts the tool to a fixed height and maintains it at a certain height. When the tool is lifted, the manipulator 8 rotates 90 degrees in the tool changing direction under the action of the wire rope 12 and the wire wheel 13.

[0026] When used specifically, the present invention provides a forming milling cutter magazine and blade changing device, with four tool rotating disks 3 and one main rotating disk 2. The four tool rotating disks 3 are used as sub-tool disk stations for placing tools, and the tool diameter range that can be placed is 160mm-250mm. Each station can rotate independently, that is, the tool rotating disk 3 can rotate above the main rotating disk 2 to facilitate the installation keyway of the tool handle to match the spindle limit positioning key, so as to facilitate the connection between the tool handle and the spindle. The tool rotating disk 3 and the main rotating disk 2 can both be rotated freely by hand, and are limited by the positioning pin 4 on the main rotating disk 2 and the positioning seat 19 below. The main rotating disk 2 is provided with a hole that matches the positioning pin 4, so as to fix the position of the tool rotating disk 3 when the main rotating disk is lifted. When any one of the holes on the disc 2 coincides with the position of the chassis positioning seat 19, the tool rotary disc 3 corresponding to the position hole reaches the knife disc lifting position. At this time, the positioning pin 4 is inserted into the position hole and the positioning seat 19, and the tool rotary disc 3 can be positioned. The positioning method has good structural rigidity and is easy to maintain. During use, the machine tool spindle moves to a fixed position above the tool magazine, that is, above the main rotary disc 2, and the tool rotary disc 3 corresponding to the spindle below has the function of lifting the tool. By starting the lifting cylinder 15, the knife disc slider 29 at the bottom of the tool rotary disc 3 can be pushed upward, thereby pushing the tool rotary disc 3 up. After the tool is lifted, the spindle can tighten the tool to complete the connection, and the four tools installed on the basic base 1 can be rotated to the position of the tool lifting device respectively;

[0027] When replacing the blade, after rotating the tool that needs to replace the blade to the fixed tool changing position, the manipulator 8 releases and drops to the tool position. The manipulator 8 clamps the tool, then raises the tool to a fixed height and maintains it at a certain height. When the tool is lifted, the manipulator 8 rotates 90 degrees in the tool changing direction under the action of the wire rope 12 and the wire wheel 13, and keeps its position unchanged after the action is completed. At this time, under the action of the rotating wheel, the operator can rotate the tool to replace the blade. Specifically, when lifting the manipulator 8, the manipulator lifting cylinder 22 works to drive the rotating gear 21 to move up and down. During the up and down movement of the rotating gear 21, the chain is pulled, and the connected chain pulls the manipulator 8 to move on the guiding slide rail 11. When the manipulator lifting cylinder 22 raises the manipulator 8 along the guiding slide rail 11, at the same time, the wire rope 12 on the side of the lifting ring 14 is stressed. Under the action of the wire wheel 13, the wire rope 12 on the side of the manipulator base 10 is pulled, driving the manipulator 8 to rotate. After the manipulator lifting cylinder 22 is lifted to the corresponding height, the manipulator rotates 90°. And the clamping is realized by the manipulator clamping cylinder 20 pushing out and the connecting rod 23 driving the clamp arm 26 and the clamp seat 27 to move inward. After clamping the tool, the tool can rotate through the rotating wheel 7;

[0028] The design of the whole device for the forming milling cutter magazine and the blade replacement device has changed the existing situation of manual tool setting, tool unloading on the spindle of the forming milling cutter and manual handling and flipping of the forming tool to replace the blade. It has realized the functions of automatic tool setting on the spindle of the forming milling cutter and automatically flipping the tool to replace the blade, improved the automation level, reduced the labor intensity, and is very convenient to use.

[0029] In the middle of the tool rotating disk base 16, there is a tool rotating disk bearing 17 corresponding to the tool rotating disk 3. The bottom of the tool rotating disk 3 is fixedly connected with a tool dividing disk slider 29. The tool dividing disk slider 29 is slidably connected with the sleeve of the tool rotating disk bearing 17. At the bottom of the tool rotating disk base 16, a lifting cylinder 15 is installed. The output end of the lifting cylinder 15 contacts the bottom of the tool dividing disk slider 29.

[0030] On one side of the top end of the basic base 1 close to the main rotating disk base 28, a positioning seat 19 is installed. The bottom of the positioning pin 4 is clamped in the middle of the positioning seat 19. The manipulator 8 includes a rotating shaft base 30, a manipulator clamping cylinder 20, a connecting rod 23, a connecting pin 24, a rotating shaft 25, a clamp arm 26 and a clamp seat 27.

[0031] On the top of the rotating shaft base 30, a manipulator clamping cylinder 20 is installed. In the middle of the rotating shaft base 30, there is a connecting rod 23. The output end of the manipulator clamping cylinder 20 is connected with the connecting rod 23. The bottom of the rotating shaft base 30 is rotatably connected with a clamp arm 26 through a rotating shaft 25. One end of the connecting rod 23 is connected with the clamp arm 26 through a connecting pin 24. The bottom of the clamp arm 26 is connected with a clamp seat 27. On both sides of the clamp seat 27, rotating wheels 7 are installed.

[0032] A chain is provided on the surface of the rotating gear 21, and the rotating gear 21 is connected to the guide slide rail 11 through the chain. Several pulleys 13 are installed on the surface of the manipulator base 10, and a wire rope 12 is provided on the surface of the pulley 13. A hanging ring 14 is installed on the top of the manipulator position correction seat 5, and the wire rope 12 is wound and connected with the hanging ring 14.

[0033] When used specifically, the present invention provides a forming milling cutter magazine and blade changing device, with four tool rotating disks 3 and one main rotating disk 2. The four tool rotating disks 3 are used as sub-tool disk stations for placing tools, and the tool diameter range that can be placed is 160mm-250mm. Each station can rotate independently, that is, the tool rotating disk 3 can rotate above the main rotating disk 2 to facilitate the installation keyway of the tool handle to match the spindle limit positioning key, so as to facilitate the connection between the tool handle and the spindle. The tool rotating disk 3 and the main rotating disk 2 can both be rotated freely by hand, and are limited by the positioning pin 4 on the main rotating disk 2 and the positioning seat 19 below. The main rotating disk 2 is provided with a hole that matches the positioning pin 4, so as to fix the position of the tool rotating disk 3 when the main rotating disk is lifted. When any one of the holes on the disc 2 coincides with the position of the chassis positioning seat 19, the tool rotary disc 3 corresponding to the position hole reaches the knife disc lifting position. At this time, the positioning pin 4 is inserted into the position hole and the positioning seat 19, and the tool rotary disc 3 can be positioned. The positioning method has good structural rigidity and is easy to maintain. During use, the machine tool spindle moves to a fixed position above the tool magazine, that is, above the main rotary disc 2, and the tool rotary disc 3 corresponding to the spindle below has the function of lifting the tool. By starting the lifting cylinder 15, the knife disc slider 29 at the bottom of the tool rotary disc 3 can be pushed upward, thereby pushing the tool rotary disc 3 up. After the tool is lifted, the spindle can tighten the tool to complete the connection, and the four tools installed on the basic base 1 can be rotated to the position of the tool lifting device respectively;

[0034] When replacing the blade, after rotating the tool that needs to replace the blade to the fixed tool change position, the manipulator 8 loosens and drops to the tool position. The manipulator 8 clamps the tool, then raises the tool to a fixed height and maintains it at a certain height. When the tool is lifted, the manipulator 8 rotates 90 degrees in the tool change direction under the action of the steel wire rope 12 and the wire wheel 13. After the action is completed, it remains in place. The rotating seat 9 is provided with fixing holes and fixing pins for positioning the rotated rotating seat 9. At this time, under the action of the rotating wheel, an operator can rotate the tool to replace the blade. Specifically, when lifting the manipulator 8, the manipulator lifting cylinder 22 works to drive the rotating gear 21 to move up and down. During the up and down movement of the rotating gear 21, the chain is pulled, and the connected chain pulls the manipulator 8 to move on the guiding slide rail 11. When the manipulator lifting cylinder 22 lifts and the chain drives the manipulator 8 to rise along the guiding slide rail 11, at the same time, the steel wire rope 12 on the side of the lifting ring 14 is stressed. Under the action of the wire wheel 13, the steel wire rope 12 on the side of the manipulator base 10 is pulled to drive the manipulator 8 to rotate. After the manipulator lifting cylinder 22 is lifted to the corresponding height, the manipulator rotates 90°. And the clamping is realized by the manipulator clamping cylinder 20 pushing out and the connecting rod 23 driving the clamp arm 26 and the clamp seat 27 to move inward. After clamping the tool, the tool can rotate through the rotating wheel 7;

[0035] The design of the entire device for the forming milling cutter magazine and the blade replacement device has changed the existing situation of manual tool setting on the spindle of the forming milling cutter, tool unloading, and manual handling and flipping of the forming tool to replace the blade. It has realized the functions of automatic tool setting on the spindle of the forming milling cutter and automatic flipping of the tool to replace the blade, improved the automation level, reduced the labor intensity, and is very convenient to use.
