[0002] In the current thriving modern manufacturing industry, horizontal machining machine tools play an important role in the field of complex component machining due to their high precision and stability. To fully exploit their potential, compatible special-shaped cutters have emerged to precisely meet specific process requirements and promote machining precision and efficiency.

[0003] The existing special-shaped cutters for horizontal machining machine tools are mostly connected to the machine tool through bolts, and the special-shaped cutters wear out quickly, often requiring frequent replacement. The large number of bolts and the cumbersome screwing process consume a lot of time for workers and are not conducive to the use of special-shaped cutters. SUMMARY

[0004] Therefore, the utility model provides a special-shaped cutter for a horizontal machining machine tool, which mainly solves the technical problem that special-shaped cutters are mostly connected to the machine tool through bolts, and the special-shaped cutters wear out quickly, often requiring frequent replacement. The large number of bolts and the cumbersome screwing process consume a lot of time for workers and are not conducive to the use of special-shaped cutters.

[0005] To achieve the above purpose, the utility model adopts the following technical scheme: a special-shaped cutter for a horizontal machining machine tool, comprising a mounting shell, a rotating groove is formed in the inside of the mounting shell, a ratchet wheel is movably installed on the inner wall of the rotating groove, a plurality of inclined grooves are formed in the side wall of the ratchet wheel, the number of the inclined grooves is six, a first moving groove is formed in the inner wall of the rotating groove, the number of the first moving grooves is six, a spring groove is formed in the inner wall of the first moving groove, a positioning pin is arranged in the inside of the spring groove, a connecting strip is fixedly connected to the side wall of the positioning pin, the connecting strip is located in the inside of the first moving groove, a moving column is fixedly connected to the end of the connecting strip away from the positioning pin, the moving column is located in the inside of the inclined groove, a first installation groove is formed in the side wall of the mounting shell, a connecting block is arranged in the inside of the first installation groove, a cutter head is fixedly connected to the side wall of the connecting block, a plurality of positioning grooves are formed in the side wall of the connecting block, the number of the positioning grooves is six, and the positioning pin is located in the inside of the positioning groove.

[0006] By adopting the above technical scheme, the cutter head can be quickly removed from the mounting shell, greatly saving the time for replacing the cutter head and facilitating the use of the special-shaped cutter.

[0007] As a further description of the above technical scheme:

[0008] A spring is fixedly connected to the inner wall of the spring groove, and one end of the spring is fixedly connected to the side wall of the positioning pin.

[0009] By adopting the above technical solution, the spring can assist the positioning pin in resetting.

[0010] As a further description of the above technical solution:

[0011] The outer surface of the mounting shell is provided with a threaded groove, the inner wall of the threaded groove is provided with a second movable groove, the inner surface of the threaded groove is threadedly connected with a threaded shaft, the side wall of the threaded shaft is movably installed with a limit pin, and the end of the threaded shaft away from the limit pin is fixedly connected with a torsion disc.

[0012] By adopting the above technical solution, turning the torsion disc can drive the threaded shaft to rotate, which in turn can drive the threaded shaft, the torsion disc, and the limit pin to move closer to or away from the ratchet. When the threaded shaft, the torsion disc, and the limit pin are close to the ratchet until the torsion disc can no longer be turned, the limit pin can restrict the ratchet, so that the ratchet can no longer rotate, thus achieving the locking effect. Conversely, the unlocking effect can be achieved.

[0013] As a further description of the above technical solution:

[0014] The outer surface of the torsion disc is provided with friction grooves, and there are multiple friction grooves.

[0015] By adopting the above technical solution, the friction groove can increase the friction when the twisting disc twists, making it easier to twist the twisting disc.

[0016] As a further description of the above technical solution:

[0017] A lever is fixedly connected to the outer surface of the ratchet, and a lever groove is provided on the outer surface of the mounting housing, with the lever located inside the lever groove.

[0018] By adopting the above technical solution, the paddle can drive the ratchet to rotate, and the paddle groove can limit the range of rotation of the paddle.

[0019] As a further description of the above technical solution:

[0021] By adopting the above technical solution, the second mounting slot is used to connect with the output end of the external drive device.

[0022] As a further description of the above technical solution:

[0023] The inner wall of the second mounting groove is provided with keyways, and the number of keyways is four.

[0024] By adopting the above technical solution, the keyway is used to make the mounting shell more accurately positioned when installed on the output end of the external drive device.

[0025] As a further description of the above technical solution:

[0026] The inner wall of the second mounting groove is provided with positioning holes, and the number of positioning holes is two.

[0027] By adopting the above technical solution, the positioning hole is used to assist in installing the housing onto the output end of the external drive device.

[0028] By employing the above technical solution, the irregular-shaped cutting tool for horizontal machining tools of this utility model has at least the following beneficial effects:

[0029] Compared with existing technologies, this non-standard cutting tool for horizontal machining tools comprises a tool head, a torsion disc, a threaded shaft, a limit pin, a ratchet, a shift plate, a slant groove, a positioning pin, a connecting strip, a moving column, a spring, a positioning groove, a connecting block, and a mounting housing. When the tool head needs to be replaced, first, the torsion disc is turned to move the torsion disc, threaded shaft, and limit pin away from the ratchet, releasing the ratchet from its lock. Then, the shift plate is moved to rotate the ratchet counterclockwise. Due to the presence of the slant groove, adjacent positioning pins, connecting strips, and moving columns are moved away from each other, the spring is compressed, and the positioning pin disengages from the positioning groove. This allows the connecting block and tool head to be replaced. Remove the tool head from the mounting housing, or vice versa, fix the connecting block and the tool head in the mounting housing. After fixing, rotate the torsion disc to bring the limit pin close to the ratchet and lock the ratchet again. Compared with existing special-shaped tools, which are mostly connected to the machine tool by bolts, special-shaped tools wear out quickly and often have a short replacement cycle. The bolts are numerous and cumbersome to tighten, which consumes a lot of the operator's time and is not conducive to the use of special-shaped tools. This special-shaped tool for horizontal machining tools can quickly remove the tool head from the mounting housing, which greatly saves the time of replacing the tool head and is conducive to the use of special-shaped tools.

[0042] To make the technical problems, technical solutions, and beneficial effects to be solved by this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and are not intended to limit the scope of this application.

[0043] Reference Figures 1-10 This utility model provides a special-shaped cutting tool for a horizontal machining center: it includes a mounting shell 1, a rotating groove 2 inside the mounting shell 1, a ratchet 3 movably mounted on the inner wall of the rotating groove 2, six inclined grooves 4 on the side wall of the ratchet 3, a first moving groove 9 on the inner wall of the rotating groove 2, six first moving grooves 9, a spring groove 5 on the inner wall of the first moving groove 9, a positioning pin 6 inside the spring groove 5, a connecting strip 7 fixedly connected to the side wall of the positioning pin 6, the connecting strip 7 being located inside the first moving groove 9, a moving column 8 fixedly connected to the end of the connecting strip 7 away from the positioning pin 6, the moving column 8 being located inside the inclined groove 4, a first mounting groove 11 on the side wall of the mounting shell 1, a connecting block 12 inside the first mounting groove 11, and a cutting tool head 13 fixedly connected to the side wall of the connecting block 12;

[0044] When the cutter head 13 needs to be replaced, first turn the torsion disc 18 to move the torsion disc 18, threaded shaft 17 and limit pin 19 away from the ratchet 3, release the lock on the ratchet 3, and then turn the dial plate 21 to drive the ratchet 3 to rotate counterclockwise. Due to the presence of the inclined groove 4, the adjacent positioning pin 6, connecting bar 7 and moving column 8 can be moved away from each other, the spring 10 is compressed, and the positioning pin 6 is disengaged from the positioning groove 14. Then the connecting block 12 and the cutter head 13 can be removed from the mounting shell 1. Conversely, the connecting block 12 and the cutter head 13 can be fixed in the mounting shell 1. After fixing, turn the torsion disc 18 to move the limit pin 19 close to the ratchet 3 to lock the ratchet 3 again. The side wall of the connecting block 12 is provided with positioning grooves 14. There are six positioning grooves 14, and the positioning pin 6 is located inside the positioning groove 14.

[0045] A spring 10 is fixedly connected to the inner wall of the spring groove 5. The spring 10 can assist the positioning pin 6 in resetting. One end of the spring 10 is fixedly connected to the side wall of the positioning pin 6. A threaded groove 16 is opened on the outer surface of the mounting shell 1. A second moving groove 15 is opened on the inner wall of the threaded groove 16. A threaded shaft 17 is threadedly connected to the inner surface of the threaded groove 16. A limit pin 19 is movably installed on the side wall of the threaded shaft 17. A torsion disc 18 is fixedly connected to the end of the threaded shaft 17 away from the limit pin 19. Twisting the torsion disc 18 can drive the threaded shaft 17 to rotate, which can in turn drive the threaded shaft 17, the torsion disc 18 and the limit pin 19 to move closer to or away from the ratchet 3. When the threaded shaft 17, the torsion disc 18 and the limit pin 19 move closer to the ratchet 3 until the torsion disc 18 can no longer be twisted, the ratchet 3 can be restricted by the limit pin 19, so that the ratchet 3 can no longer rotate, achieving the locking effect. Conversely, the unlocking effect can be achieved.

[0046] The outer surface of the twisting disk 18 is provided with friction grooves 20. The friction grooves 20 can increase the friction when the twisting disk 18 twists, making it easier to twist the twisting disk 18. There are multiple friction grooves 20.

[0047] A lever 21 is fixedly connected to the outer surface of the ratchet 3. A lever groove 22 is provided on the outer surface of the mounting housing 1. Moving the lever 21 can drive the ratchet 3 to rotate. The lever groove 22 can limit the range of rotation of the lever 21. The lever 21 is located inside the lever groove 22.

[0048] The side wall of the mounting housing 1 is provided with a second mounting groove 23, which is used to dock with the output end of the external drive device. The cross-sectional shape of the second mounting groove 23 is a regular hexagon. The inner wall of the second mounting groove 23 is provided with a keyway 24, which is used to make the mounting housing 1 more accurately positioned when installed on the output end of the external drive device. There are four keyways 24. The inner wall of the second mounting groove 23 is provided with positioning holes 25, which are used to assist the mounting housing 1 in being installed on the output end of the external drive device. There are two positioning holes 25.

[0049] Working principle: When it is necessary to replace the cutter head 13, first turn the torsion disc 18 to move the torsion disc 18, threaded shaft 17 and limit pin 19 away from the ratchet 3, release the lock on the ratchet 3, and then turn the lever 21 to drive the ratchet 3 to rotate counterclockwise. Due to the presence of the inclined groove 4, the adjacent positioning pin 6, connecting bar 7 and moving column 8 can be moved away from each other, the spring 10 is compressed, and the positioning pin 6 is disengaged from the positioning groove 14. Then the connecting block 12 and the cutter head 13 can be removed from the mounting shell 1. Conversely, the connecting block 12 and the cutter head 13 can be fixed in the mounting shell 1. After fixing, turn the torsion disc 18 to move the limit pin 19 close to the ratchet 3 to lock the ratchet 3 again.
