Description

Technical Field

[0001] This utility model relates to the field of diamond cutting tools and related products, specifically a diamond cutting tool with a protective structure. Background Technology

[0002] Diamond tools have advantages such as extremely high hardness and wear resistance, low coefficient of friction, high elastic modulus, high thermal conductivity, low coefficient of thermal expansion, and low affinity for non-ferrous metals. They can be used for precision machining of non-metallic hard and brittle materials such as graphite, high wear-resistant materials, composite materials, high silicon aluminum alloys and other tough non-ferrous metal materials. Most diamond tools need to be mounted on the mounting base of milling machines or CNC machine tools before use.

[0003] However, existing diamond tools do not have protective structures, and collisions between tools are likely to occur during placement or transportation, leading to tool damage. Utility Model Content

[0004] The purpose of this invention is to provide a diamond cutting tool with a protective structure to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a diamond cutting tool with a protective structure, comprising a tool shank and a sheath. A positioning sleeve is fixedly fitted onto the tool shank, and the sheath is slidably fitted onto the tool shank. A positioning frame is fixedly connected to one end of the sheath near the positioning sleeve. Insert blocks are fixedly connected to both side walls of the positioning frame. The positioning sleeve has insertion ports corresponding to the insert blocks. A sliding groove is provided on one outer wall of the insert block. A locking block is slidably connected within the sliding groove. Support blocks are fixedly connected to both outer walls of the locking block. A sliding rod is slidably inserted into the support block. The sliding rod is fixedly connected to the inner wall of the sliding groove. A first spring is fitted onto the sliding rod. The two ends of the first spring are fixedly connected to the support block and the inner wall of the sliding groove, respectively. A locking groove corresponding to the locking block is provided on the inner side wall of the sliding groove. One end of the locking block has an inclined cross-section. An oil injection pipe is fixedly inserted into one end of the sheath, and a sealing plug is inserted into the oil injection pipe.

[0006] Preferably, the sheath is made of waterproof nylon fabric.

[0007] Preferably, an anti-detachment block is fixedly connected to one end of the slide rod.

[0008] Preferably, the outer wall of the sealing plug is provided with external threads, the oil injection pipe is provided with a threaded opening, and the sealing plug is threadedly inserted into the oil injection pipe.

[0009] Preferably, the positioning frame is connected to the protective sleeve.

[0010] Preferably, the positioning sleeve is provided with a sliding opening communicating with the slot, and a pressing rod is slidably inserted into the sliding opening. One end of the pressing rod is fixedly sleeved with a limiting sleeve, and a second spring is sleeved on the pressing rod. The two ends of the second spring are fixedly connected to the limiting sleeve and the positioning sleeve, respectively.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] This diamond cutting tool with a protective structure is protected by inserting the tool shank into a sheath. A block on one side of the positioning frame is inserted into the slot on the positioning sleeve, simultaneously pressing against a locking block. The block's inclined surface causes it to retract into a groove. Meanwhile, a support block slides on the slide rod, compressing a first spring. After the block is fully inserted, the first spring generates a rebound force, causing the locking block to return to its stable position in the slot on the positioning sleeve, thus installing the sheath. An oil injection pipe allows for the injection of lubricating oil to prevent the tool from rusting. This invention, through the setting of external protective components, can seal and protect the tool, preventing damage from external influences. Attached Figure Description

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0017] Please see Figure 1-2This utility model provides an embodiment of a diamond cutting tool with a protective structure, comprising a tool shank 1 and a sheath 2. A positioning sleeve 3 is fixedly sleeved on the tool shank 1, and the sheath 2 is slidably sleeved on the tool shank 1. A positioning frame 4 is fixedly connected to one end of the sheath 2 near the positioning sleeve 3. Insert blocks 5 are fixedly connected to both side walls of the positioning frame 4. The positioning sleeve 3 has insertion holes corresponding to the insert blocks 5. A sliding groove is provided on one outer wall of the insert block 5. A locking block 6 is slidably connected in the sliding groove. Support blocks 7 are fixedly connected to both outer walls of the locking block 6. A sliding rod 8 is slidably inserted into the support block 7. The sliding rod 8 is fixedly connected to the inner wall of the sliding groove. A first spring 9 is sleeved on the sliding rod 8. The two ends of the first spring 9 are fixedly connected to the support block 7 and the inner wall of the sliding groove, respectively. The inner wall is provided with a slot corresponding to the locking block 6. One end of the locking block 6 is provided with an inclined cross section. An oil injection pipe 10 is fixedly inserted into one end of the sleeve 2. A sealing plug 11 is inserted into the oil injection pipe 10. Specifically, the tool bar 1 is inserted into the sleeve 2 and protected by the sleeve 2. At this time, the insertion block 5 on one side of the positioning frame 4 is aligned with the insertion port on the positioning sleeve 3 and inserted, while pressing against the locking block 6. Under the action of the inclined cross section of the locking block 6, the locking block 6 is forced to retract into the slide groove. At the same time, the support block 7 slides on the slide rod 8 to compress the first spring 9. After the insertion block 5 is fully inserted, the first spring 9 generates a rebound force, which causes the locking block 6 to return to a stable locking position in the slot on the positioning sleeve 3, thus realizing the installation of the sleeve 2. The oil injection pipe 10 can inject lubricating oil to prevent the tool from rusting.

[0018] In this embodiment, the sheath 2 is made of waterproof nylon cloth and has waterproof performance; an anti-detachment block 12 is fixedly connected to one end of the slide rod 8; the outer wall of the sealing plug 11 is provided with external threads, and the oil injection pipe 10 is provided with a threaded opening. The sealing plug 11 is threadedly inserted into the oil injection pipe 10 for easy disassembly and assembly; the positioning frame 4 is connected to the sheath 2; the positioning sleeve 3 is provided with a sliding opening that communicates with the slot, and a pressing rod 13 is slidably inserted into the sliding opening. One end of the pressing rod 13 is fixedly sleeved with a limiting sleeve 14, and a second spring 15 is sleeved on the pressing rod 13. The two ends of the second spring 15 are fixedly connected to the limiting sleeve 14 and the positioning sleeve 3 respectively. The pressing rod 13 is used to press the locking block 6 to make it disengage from the slot, which facilitates the disassembly of the sheath 2.

[0019] Working principle: First, insert the tool holder 1 into the sleeve 2 for protection. At this time, the insert block 5 on one side of the positioning frame 4 is aligned with the insertion port on the positioning sleeve 3 and inserted. At the same time, the pressing block 6 is pushed back. Under the action of the inclined section of the block 6, the block 6 is pushed back into the groove. Meanwhile, the support block 7 slides on the slide rod 8 to compress the first spring 9. After the insert block 5 is fully inserted, the first spring 9 generates a rebound force, which causes the block 6 to return to a stable position in the groove on the positioning sleeve 3, thus realizing the installation of the sleeve 2. The oil injection pipe 10 can inject lubricating oil to prevent the tool from rusting.
