Description

Technical Field

[0001] This utility model relates to the field of milling cutter technology, specifically to chip removal and vibration damping groove inserts. Background Technology

[0002] Grooving inserts are cutting tool inserts specifically used for grooving, cutting, or cutting off in machining. They are commonly found on lathes, milling machines, CNC machining centers, and other equipment.

[0003] Application number CN201510435705.0 discloses an end-face grooving insert and a cutting tool using the insert. The end-face grooving insert includes an insert body with outwardly protruding cutting heads at both ends. The insert body has mounting holes for installation and fixation. The cutting tool includes the end-face grooving insert, a tool holder, and a fixing connector. The tool holder has an insert mounting seat, and the fixing connector passes through the mounting holes in the insert body, fixing the end-face grooving insert to the insert mounting seat. This invention provides an end-face grooving insert and a cutting tool using the same insert. The end-face grooving insert is detachable and replaceable, making it economical and practical. The cutting tool offers excellent machining quality and a long service life, making it particularly suitable for end-face grooving.

[0004] However, this blade is only fixed to the tool holder by two bolts, which can easily cause the bolts to loosen due to vibration during the cutting process. Loose bolts can cause the blade to shift and vibrate, which will affect the grooving quality. At the same time, the grooving blade lacks certain protective measures when it is not in use. Therefore, a chip removal and vibration-resistant grooving blade is proposed. Utility Model Content

[0005] To address the problems in the prior art, this utility model provides a chip removal and vibration-damping groove blade.

[0006] The technical solution adopted by this utility model to solve its technical problem is a chip removal and vibration-damping groove blade, including a handle and a blade body. The top and bottom ends of the blade body are provided with slots, and there are multiple slots. One side of the handle is provided with an installation groove. The top and bottom of the installation groove are provided with locking blocks, and there are multiple locking blocks. The multiple locking blocks are adapted to the multiple slots.

[0007] The top and bottom ends of the handle are provided with sliding grooves for sliding installation of sliders. There are two sliders, which are located at the top and bottom of the inner side of the limiting sleeve. A limiting block is provided on the inner side of the limiting sleeve, and one side of the limiting block is in close contact with one side of the blade body.

[0008] By adopting the above technical solution, a triple fixing mechanism is formed by the embedded cooperation of the slot and the block, the guide structure of the slider and groove of the limiting sleeve, and the bolt fastening. After the blade body is pushed into the installation groove, the precise engagement of the block and the slot achieves initial positioning. The bolt passes through the third bolt hole and the second bolt hole to form a rigid connection. Finally, when the limiting sleeve is slidably installed, its inner limiting block is close to the side of the blade. With the limiting of the groove and the slider, the lateral displacement of the blade is effectively suppressed. Even if vibration occurs during operation, the blade can still remain stable, avoiding cutting deviation or safety hazards caused by loosening.

[0009] Specifically, both ends of the blade body are fixedly connected to cutting heads, a third bolt hole is opened inside the blade body, a second bolt hole is opened on the inner side of the mounting groove, and the third bolt hole is adapted to the second bolt hole.

[0010] By adopting the above technical solution, the blade body performs cutting operations through the cutting head. Its double-end design can extend the service life of the blade (the other end can be replaced after one end is worn). After installation, the blade body and the tool holder need to be further locked by passing the bolts through the third bolt hole in the blade body and the second bolt hole in the mounting groove in sequence. The bolt connection not only enhances the structural stability, but also facilitates the later disassembly and replacement of the blade body or adjustment of the cutting head direction.

[0011] Specifically, the top and bottom of the knife handle are provided with first bolt holes, and the top and bottom of the limiting sleeve are provided with fourth bolt holes, and the first bolt holes and the fourth bolt holes are adapted to each other.

[0012] By adopting the above technical solution, after the limiting sleeve slides into the groove of the tool holder and is positioned by the slider, the bolts need to be passed through the fourth bolt hole of the limiting sleeve and the first bolt hole of the tool holder in sequence to fix the two together. This step ensures that the limiting sleeve and the tool holder form a rigid whole and prevents the limiting sleeve from sliding due to vibration during operation.

[0013] Specifically, a magnetic block is provided at one end of the slide groove, and the magnetic block is magnetically connected to the slider.

[0014] By adopting the above technical solution, when installing the limiting sleeve, after the slider slides along the slide groove to the end, the magnetic block will magnetically attract the slider, temporarily fixing it in the predetermined position of the slide groove. This design simplifies the subsequent operation of aligning the bolts with the fourth bolt hole and the first bolt hole, avoids the limiting sleeve from accidentally slipping off before the bolts are installed, and improves assembly efficiency.

[0015] Specifically, a protective cover is movably inserted into the inside of the limiting sleeve, and a groove is provided on one side of the limiting sleeve, with one side of the protective cover located inside the groove.

[0016] By adopting the above technical solution, when the slotted blade is idle, the protective cover in the groove can be pushed to extend out of the limiting sleeve and completely cover the cutting head. The protective cover is stored inside the limiting sleeve through a sliding structure, which not only does not occupy extra space, but also effectively prevents the sharp cutting head from accidentally scratching people or objects, thus improving safety.

[0017] The beneficial effects of this utility model are:

[0018] The chip-removing and vibration-damping grooved blade of this utility model forms a triple fixing mechanism through the embedded engagement of the slot and the locking block, the guide structure of the slider groove of the limiting sleeve, and the bolt fastening. After the blade body is pushed into the mounting groove, the precise engagement of the locking block and the slot achieves initial positioning; the bolt passes through the third bolt hole and the second bolt hole to form a rigid connection; finally, when the limiting sleeve is slidably installed, its inner limiting block is close to the side of the blade, and with the limiting of the groove and the slider, it effectively suppresses the lateral displacement of the blade. Even if vibration occurs during operation, the blade can still remain stable, avoiding cutting deviation or safety hazards caused by loosening. Attached Figure Description

[0026] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0027] As one embodiment of this utility model, such as Figures 1-5As shown, the chip removal and vibration damping groove blade of this utility model includes a handle 7 and a blade body 8. The top and bottom ends of the blade body 8 are provided with slots 10, and there are multiple slots 10. The handle 7 is provided with a mounting groove 4 on one side. The top and bottom of the mounting groove 4 are provided with locking blocks 6, and there are multiple locking blocks 6. The multiple locking blocks 6 are adapted to the multiple slots 10.

[0028] The top and bottom ends of the handle 7 are provided with sliding grooves 1, which are used for sliding installation of sliders 14. There are two sliders 14, which are located at the top and bottom of the inner side of the limiting sleeve 13. A limiting block 15 is provided on the inner side of the limiting sleeve 13, and one side of the limiting block 15 is in close contact with one side of the blade body 8.

[0029] When installing the insert body 8, it should be pushed horizontally into the mounting groove 4 of the tool holder 7, so that the slots 10 at both ends of the insert body 8 are aligned with the corresponding locking blocks 6 in the mounting groove 4. Once the locking blocks 6 are fully embedded in the slots 10, the insert body 8 is initially fixed to the tool holder 7. Subsequently, the limiting sleeve 13 is slidably installed along the sliding grooves 1 at both ends of the tool holder 7 via its internal slider 14, until the limiting block 15 on the inner side of the limiting sleeve 13 is tightly fitted against the side of the insert body 8. This double fixing design (locking block 6 + limiting block 15) can prevent the insert body 8 from shifting laterally or loosening due to force during cutting.

[0030] The present invention also includes a cutting head 11 fixedly connected to both ends of the blade body 8, a third bolt hole 9 opened inside the blade body 8, and a second bolt hole 5 opened on one side of the mounting groove 4, wherein the third bolt hole 9 and the second bolt hole 5 are adapted to each other.

[0031] During use, the blade body 8 performs cutting operations through the cutting head 11. Its double-end design can extend the service life of the blade (the other end can be replaced after one end is worn). After installation, the blade body 8 and the tool holder 7 are further locked by passing bolts through the third bolt hole 9 and the second bolt hole 5 in the mounting groove 4 in sequence. The bolt connection not only enhances the structural stability, but also facilitates the later disassembly and replacement of the blade body 8 or adjustment of the direction of the cutting head 11.

[0032] The present invention also includes that the top and bottom ends of the knife handle 7 are provided with first bolt holes 3, and the top and bottom ends of the limiting sleeve 13 are provided with fourth bolt holes 12, wherein the first bolt holes 3 and the fourth bolt holes 12 are adapted to each other.

[0033] When in use, after the limiting sleeve 13 slides into the groove 1 of the tool holder 7 through the slider 14 and is positioned, the bolts need to be passed through the fourth bolt hole 12 of the limiting sleeve 13 and the first bolt hole 3 of the tool holder 7 in sequence to fix the two together. This step ensures that the limiting sleeve 13 and the tool holder 7 form a rigid whole and prevents the limiting sleeve 13 from sliding due to vibration during operation.

[0034] The present invention also includes a magnetic block 2 provided at one end of the inner side of the slide groove 1, and the magnetic block 2 is magnetically connected to the slider 14.

[0035] When using the limit sleeve 13, after the slider 14 slides along the slide groove 1 to the end, the magnetic block 2 will magnetically attract the slider 14, temporarily fixing it in the predetermined position of the slide groove 1. This design simplifies the subsequent operation of aligning the bolts with the fourth bolt hole 12 and the first bolt hole 3, avoids the limit sleeve 13 from accidentally slipping off before the bolts are installed, and improves assembly efficiency.

[0036] The present invention also includes a protective cover 16 movably inserted inside the limiting sleeve 13, a groove 17 being provided on one side of the limiting sleeve 13, and one side of the protective cover 16 being located inside the groove 17.

[0037] When in use, when the grooving blade is idle, the protective cover 16 in the groove 17 can be pushed out of the limiting sleeve 13 and completely cover the cutting head 11. The protective cover 16 is stored inside the limiting sleeve 13 through a sliding structure, which does not take up extra space and can effectively prevent the sharp cutting head 11 from accidentally scratching people or objects, thus improving safety. When using the grooving blade, the cutting head 11 can be quickly exposed by simply pushing the protective cover 16 back into the limiting sleeve 13.

[0038] It should be noted that there is a certain amount of friction between the protective cover 16 and the limiting sleeve 13. This provides some resistance during the pushing process of the protective cover 16.

[0039] In use, the blade body 8 is first installed into the mounting groove 4. The slots 10 of the blade body 8 are aligned with the corresponding locking blocks 6 and horizontally pushed into the mounting groove 4, ensuring the locking blocks 6 fit snugly into the slots 10. The blade body 8 is then secured by bolts passing through the third bolt hole 9 and the second bolt hole 5. Next, the limiting sleeve 13 is placed on the outside of the handle 7. The slider 14 is aligned with the slide groove 1, and the limiting block 15 is aligned with the mounting groove 4, allowing the slider 14 to slide into the slide groove 1 and the limiting block 15 to slide into the mounting groove 4. The blade body 8 is attached to one side of the blade body 8. The limit block 15 and the locking block 6 can firmly fix the blade body 8 in the mounting groove 4. Even if the bolts are loose, the blade body 8 will not displace or vibrate. Finally, the limit sleeve 13 and the tool holder 7 are fixedly connected by the bolts passing through the fourth bolt hole 12 and the first bolt hole 3 in sequence. When the cutting head 11 is not in use, the protective cover 16 in the groove 17 can be pushed out of the limit sleeve 13, so that the protective cover 16 can cover the cutting head 11 and prevent the cutting head 11 from injuring people or objects.
