Description

Technical Field

[0001] This utility model relates to the field of cutting tool devices, and in particular to a machining cutting tool device with a self-sharpening function. Background Technology

[0002] With the continuous development of global manufacturing, the demand for machining continues to increase. Various industries, such as automobile manufacturing and electronic equipment manufacturing, require a large number of machining tools and equipment. As the requirements for machining processes continue to improve, the cutting requirements for tools are also increasing accordingly.

[0003] When existing cutting tools are in use, the cutting head gradually becomes dull after continuous cutting. When the cutting performance drops to a certain level, the cutting head needs to be manually disassembled and sharpened before it can be used again, which will cause the production line to stop and thus affect the overall production progress.

[0004] Therefore, there is an urgent need to design a structure that can continuously sharpen the cutting edge of the tool during use, so that it always remains sharp, thus solving the problem of the tool gradually becoming dull after continuous cutting, which affects the production progress. Utility Model Content

[0005] To overcome the problem that the cutting head of the cutting device gradually becomes dull after continuous cutting during use, and when the cutting performance drops to a certain level, the cutting head needs to be manually disassembled and sharpened before it can be used again, which will cause the production line to stop and thus affect the overall production progress.

[0006] The technical solution of this utility model is as follows: a machining tool device with self-sharpening function, including a device mounting base plate and a structural support plate, a motor, an automatic tool lowering assembly, a grinding protective cover, a tool head self-sharpening grinding assembly, and a cylinder; the upper end of the device mounting base plate is fixedly connected to the structural support plate; the outer end of the structural support plate is equipped with a motor; the inner end of the structural support plate is equipped with an automatic tool lowering assembly; a grinding protective cover is installed through the inside of the structural support plate; the tool head self-sharpening grinding assembly is installed inside the grinding protective cover; a cylinder is installed at the side end of the grinding protective cover; the tool head self-sharpening grinding assembly includes a push plate, a movable top plate, and a grinding abrasive; the output end of the cylinder passes through the grinding protective cover and is fixedly connected to the push plate; the side end of the push plate is hinged to the movable top plate; the side end of the movable top plate is fixedly connected to the grinding abrasive.

[0007] Preferably, during the use of the cutting tool device, the push plate in the self-sharpening and polishing assembly, driven by the cylinder, moves the movable top plate and polishing abrasive disc on its side closer to the cutting edge. This allows the cutting edge to rub against the polishing abrasive disc during the up-and-down cutting motion, thus achieving a continuous polishing effect and keeping it sharp at all times. This eliminates the need for frequent machine stops to change the cutting head, allowing the processing to continue continuously and greatly improving production efficiency. Meanwhile, the rotating sleeve in the automatic unloading assembly rotates under the drive of the motor and, through the action of the connecting rod, drives the sliding sleeve block to reciprocate up and down on the side of the limit track plate. This converts the rotation of the motor into the cutting linear motion of the lower tool holder plate and the cutting edge. The sliding ball can rotate when it contacts the polishing abrasive disc, reducing the frictional impact of the polishing abrasive disc on the tool holder plate and the back of the blade.

[0008] Preferably, the self-sharpening blade assembly also includes a pressure spring, a rubber pad, an air pump, an air nozzle, a dust collection box, and an absorption hopper; a pressure spring is fixed to the side end of the push plate.

[0009] Preferably, the pressure spring is fixed to the inner end of the movable top plate; a rubber pad is provided at the side end of the push plate; and an air pump is installed at the side end of the structural support plate.

[0010] Preferably, the air pump's output pipe is connected to an air nozzle; the air nozzle is installed on both sides of the grinding protective cover; a dust collection box is provided at the outer end of the structural support plate; an absorption hopper is connected to the side end of the dust collection box; the absorption hopper passes through the structural support plate and is installed below the grinding protective cover.

[0011] Preferably, the automatic cutting assembly includes a transmission rod, a rotating sleeve, a limiting track plate, a sliding sleeve block, a connecting rod, a tool holder plate, a tool back, a sliding ball, and a cutting edge; the output shaft of the motor passes through the structural support plate and is fixedly connected to the transmission rod.

[0012] Preferably, a rotating sleeve plate is fixedly connected to the outer end of the transmission rod; a limiting track plate is fixedly connected to the inner end of the structural support plate; a sliding sleeve block is slidably connected to the outer end of the limiting track plate; and a connecting rod is hinged to the side end of the rotating sleeve plate.

[0013] Preferably, the lower end of the connecting rod is hinged to the side end of the sliding sleeve block; a tool holder plate is fixedly connected to the lower end of the sliding sleeve block; a blade back is fixedly connected to the lower end of the tool holder plate; a sliding ball is provided at the side end of the blade back; and a blade edge is welded to the lower end of the blade back.

[0014] The beneficial effects of this utility model are:

[0015] During the use of the cutting tool device, the push plate in the self-sharpening and polishing assembly, driven by the cylinder, moves the movable top plate and polishing abrasive disc on its side closer to the cutting edge. This allows the cutting edge to rub against the polishing abrasive disc during the up-and-down cutting motion, thus achieving a continuous polishing effect and keeping it sharp at all times. This eliminates the need for frequent machine stops to change the cutting head, allowing the processing to continue continuously and greatly improving production efficiency. The pressure spring provides elasticity to the movable top plate, ensuring that the polishing abrasive disc on the side can rub against the cutting edge without being damaged by excessive friction. The rubber pad further enhances the protective and cushioning effect. The air pump blows air into the polishing protective cover through the air nozzle, reducing the heat generated during polishing and causing the generated metal dust to sink downwards, facilitating the collection of metal debris by the dust collection box and absorption hopper, and preventing the spread of large amounts of debris.

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0023] Please see Figures 2-3 In this embodiment, the self-sharpening grinding assembly further includes a pressure spring 404, a rubber pad 405, an air pump 406, an air nozzle 407, a dust collection box 408, and an absorption hopper 409; a pressure spring 404 is fixedly connected to the side end of the push plate 401, and the pressure spring 404 is fixedly connected to the inner end of the movable top plate 402; a rubber pad 405 is provided on the side end of the push plate 401; an air pump 406 is installed on the side end of the structural support plate 2; the pressure spring 404 can make the movable top plate 402 elastic, so that the grinding abrasive disc 403 on the side can both rub and grind with the blade 309, without being damaged by friction. Excessive friction can cause damage. The output pipe of the air pump 406 is connected to the air nozzle 407. The air nozzle 407 is installed on both sides of the grinding protective cover 4. A dust collection box 408 is provided at the outer end of the structural support plate 2. An absorption bucket 409 is connected to the side end of the dust collection box 408. The absorption bucket 409 passes through the structural support plate 2 and is installed below the grinding protective cover 4. The air pump 406 can blow air into the grinding protective cover 4 through the air nozzle 407 to reduce the heat generated during grinding and make the generated metal dust sink downwards, so that the dust collection box 408 and the absorption bucket 409 can collect the metal debris under grinding and avoid a large amount of debris spreading.

[0024] Please see Figure 4In this embodiment, the automatic cutting assembly includes a transmission rod 301, a rotating sleeve 302, a limiting track plate 303, a sliding sleeve block 304, a connecting rod 305, a tool holder plate 306, a blade back 307, a sliding ball 308, and a cutting edge 309. The output shaft of the motor 3 passes through the structural support plate 2 and is fixedly connected to the transmission rod 301. The outer end of the transmission rod 301 is fixedly connected to the rotating sleeve 302. The inner end of the structural support plate 2 is fixedly connected to the limiting track plate 303. The outer end of the limiting track plate 303 is slidably connected to the sliding sleeve block 304. The side end of the rotating sleeve plate 302 is hinged to the connecting rod. 305 enables the rotation of motor 3 to be converted into linear cutting motion of the lower tool holder plate 306 and the cutting edge 309. The lower end of the connecting rod 305 is hinged to the side end of the sliding sleeve block 304; the lower end of the sliding sleeve block 304 is fixedly connected to the tool holder plate 306; the lower end of the tool holder plate 306 is fixedly connected to the back of the blade 307; a sliding ball 308 is provided on the side end of the back of the blade 307; the cutting edge 309 is welded to the lower end of the back of the blade 307; the sliding ball 308 can rotate when it contacts the grinding disc 403, reducing the frictional effect of the grinding disc 403 on the tool holder plate 306 and the back of the blade 307.

[0025] When working, the rotating sleeve 302 rotates under the drive of the motor 3, and through the action of the connecting rod 305, it drives the sliding sleeve 304 to move up and down on the side of the limiting track plate 303, which can convert the rotation of the motor 3 into the cutting linear motion of the lower tool holder plate 306 and the cutting edge 309.

[0026] Next, driven by the cylinder 5, the push plate 401 moves the movable top plate 402 and the grinding disc 403 on its side closer to the cutting edge 309, so that the cutting edge 309 can rub against the grinding disc 403 during the up and down cutting motion, thereby achieving the effect of continuous grinding. The sliding ball 308 can rotate when it contacts the grinding disc 403, reducing the frictional impact of the grinding disc 403 on the tool holder plate 306 and the back of the tool 307.

[0027] Finally, the pressure spring 404 can make the movable top plate 402 elastic, so that the side grinding abrasive 403 and the blade 309 can both rub and grind without being damaged by excessive friction. The rubber pad 405 can further improve the protective and buffering effect. The air pump 406 can blow air into the grinding protective cover 4 through the air nozzle 407 to reduce the heat generated during grinding and make the generated metal dust sink downward, which is convenient for the dust box 408 and the absorption hopper 409 to collect the metal debris under grinding and avoid a large amount of debris spreading.

[0028] Through the above steps, a structure can be formed that continuously sharpens the cutting edge of the tool during use, keeping it always sharp. The push plate 401 in the self-sharpening and polishing assembly is driven by the cylinder 5, causing the movable top plate 402 on its side and the polishing abrasive 403 to move closer to the cutting edge 309. This allows the cutting edge 309 to rub against the polishing abrasive 403 during the up-and-down cutting motion, thus achieving a continuous sharpening effect and keeping it always sharp. This eliminates the need for frequent machine stops to change the cutting head, allowing the processing to continue continuously and greatly improving production efficiency.

[0029] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
