Description

Technical Field

[0001] This utility model relates to the field of indexable lathe blade technology, specifically to an anti-misalignment positioning groove for an indexable lathe blade. Background Technology

[0002] The misalignment positioning groove of the indexable cutting insert is a key structure for the fit between the insert and the tool body. Its core function is to ensure that the insert can only be fixed in the one correct direction and position when it is installed, indexed, or replaced, thereby avoiding machining problems or tool damage caused by operational errors.

[0003] Chinese utility model patent CN209349533U discloses a type-indexable machine tool, which includes "a tool holder and a tool head disposed at one end of the tool holder, the tool head including a tool head body and a blade disposed within the tool head body, the tool head body having a clamping mounting hole and a blade mounting groove, the blade being installed in the blade mounting groove and fixed by a detachable upper-pressure clamping element, the upper-pressure clamping element including a spring washer and a fixing rod, the spring washer being disposed in the blade mounting groove and located above the blade, the fixing rod passing through the spring washer and the blade in sequence and engaging with the clamping mounting hole to fix the spring washer and the blade in the blade mounting groove"; however, when installing the blade by changing sides, because the upper and lower sides of the blade are the same, it is easy to install it backwards or incorrectly, and the blade has no positioning structure, so alignment is required during installation, resulting in a long installation time. Utility Model Content

[0004] The purpose of this invention is to provide a mis-installation positioning groove for indexable cutting blades, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a mis-installation positioning groove for an indexable lathe blade, comprising a blade shank, a blade head mounted on one side of the blade shank, a connecting block at the upper end of the blade head, a fixing screw at the upper end of the connecting block, a pressing spring at the bottom of the fixing screw, and an insertion hole at the bottom of the pressing spring;

[0006] The bottom of the connecting block is connected to a pressing block, the bottom of the pressing block is provided with a fixing bolt, one side of the fixing bolt is provided with a cutting blade, the bottom of the cutting blade is provided with a groove, one side of the groove is provided with an annular block, and one side of the annular block is provided with a positioning rod.

[0007] The beneficial effects of this utility model are as follows: by adding an annular block and a positioning rod, when changing the blade, first align the slot at the bottom of the blade with the positioning rod so that the positioning rod can quickly position the blade. Then, align the groove at the bottom of the blade with the annular block to cooperate with the positioning rod, so that the blade can only be installed upright while being quickly positioned.

[0008] To assist in pressing the fixing bolts:

[0009] Further configuration: The pressing block is connected to the fixing screw via a connecting block.

[0010] By adopting the above technical solution, when the fixing bolt presses and limits the blade, the pressing block is inserted into the fixing bolt, and then the connecting block is pressed against the fixing screw to prevent the fixing bolt from shaking during cutting.

[0011] To prevent the fixing screw from wobbling during operation:

[0012] Further configuration: the central axis of the fixing screw coincides with the vertical central axis of the pressing spring.

[0013] By adopting the above technical solution, when the blade is cutting, the compression spring will generate a reverse elastic force after being compressed, causing the fixing screw to loosen slightly. The elastic force of the compression spring can still continuously press the blade and maintain a stable fixed state.

[0014] To prevent reverse blade installation:

[0015] Further configuration: The bottom of the blade has a groove of the same size as the outer dimension of the annular block.

[0016] By adopting the above technical solution, when installing the blade, the groove at the bottom of the blade is aligned with the annular block to cooperate with the positioning rod, so that the blade can only be installed upright.

[0017] To achieve rapid blade positioning:

[0018] Further configuration: The positioning rods are arranged at equal angles with the center point of the annular block as the center.

[0019] By adopting the above technical solution, when installing the blade, the slot at the bottom of the blade is aligned with the positioning rod, allowing the positioning rod to quickly position the blade, thereby increasing the installation speed.

[0020] The parts of the device not covered herein are the same as or can be implemented using existing technologies. Attached Figure Description

[0026] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of the present invention in any way.

[0027] Please see Figures 1 to 4 A misalignment positioning groove for an indexable cutting tool includes a tool holder 1, a tool head 2 mounted on one side of the tool holder 1, a connecting block 3 at the upper end of the tool head 2, a fixing screw 4 at the upper end of the connecting block 3, a pressing spring 5 at the bottom of the fixing screw 4, and an insertion hole 6 at the bottom of the pressing spring 5.

[0028] The bottom of the connecting block 3 is connected to a pressing block 7. The bottom of the pressing block 7 is provided with a fixing bolt 8. A cutting blade 9 is provided on one side of the fixing bolt 8. The bottom of the cutting blade 9 is provided with a groove 10. An annular block 11 is provided on one side of the groove 10. A positioning rod 12 is installed on one side of the annular block 11.

[0029] In this embodiment, as Figure 2 As shown, the pressing block 7 is connected to the fixing screw 4 via the connecting block 3.

[0030] In this embodiment, as Figure 2 As shown, the central axis of the fixing screw 4 coincides with the vertical central axis of the pressing spring 5.

[0031] In this embodiment, as Figure 4 As shown, the bottom of the cutting blade 9 is provided with a groove 10 of the same size as the outer dimension of the annular block 11.

[0032] In this embodiment, as Figure 3 As shown, the positioning rods 12 are arranged at equal angles with the center point of the annular block 11 as the center.

[0033] The mis-installation prevention positioning groove of this indexable cutting tool works as follows:

[0034] First, when changing the blade, align the slot at the bottom of the cutting blade 9 with the positioning rod 12 to quickly position the cutting blade 9. Then, align the groove 10 at the bottom of the cutting blade 9 with the annular block 11 to cooperate with the positioning rod 12, so that the cutting blade 9 can only be installed upright and quickly positioned to install the cutting blade 9 on the blade head 2, preventing misinstallation during installation. Then, fix it with the fixing bolt 8. Then, insert the pressing block 7 on the connecting block 3 into the fixing bolt 8. Then, insert the pressing spring 5 and the fixing screw 4 into the insertion hole 6 to press and fix the connecting block 3. When the pressing spring 5 is compressed, it will generate a reverse elastic force. Even if the fixing screw 4 is slightly loose, the elastic force of the pressing spring 5 can still keep the blade pressed and maintain a stable fixed state.
