Description

Technical Field

[0001] This utility model relates to the field of grooving machine technology, and more specifically, to a twist drill bit grooving machine. Background Technology

[0002] The precision of the grooves, including the helix angle, groove depth, and groove width consistency, directly determines the drilling efficiency, hole wall smoothness, and drill bit lifespan. As a key piece of equipment specifically designed for processing drill bit grooves, the twist drill bit grinding machine needs to achieve precise positioning and clamping of the drill bit through a precise mechanical structure, and work with the grinding wheel to complete the groove grinding. It is one of the core pieces of equipment to ensure the production quality of twist drill bits.

[0003] However, during the grinding process, a large amount of metal shavings, or grinding waste, are generated. If these wastes are not cleaned up in time, they will accumulate at the contact points between the clamping components and the drill bit, further increasing the risk of loosening. On the other hand, the wastes will splash or fall onto the surfaces of the equipment guide rails and transmission components, and long-term accumulation will cause wear on the components, shorten the service life of the equipment, and also pollute the working environment, increasing the cleaning burden on the operators.

[0016] 2. This utility model utilizes an adsorption-type cleaning component that generates negative pressure through an exhaust fan to actively suck up metal shavings produced during grinding in real time. Large particles are then filtered by an isolation mesh inside the collection casing, while fine dust is adsorbed by an electromagnet. This achieves a highly efficient cleaning effect through active adsorption and dual filtration. This not only eliminates the problem of shavings splashing and polluting the working environment, and increasing the burden of manual cleaning, but also prevents shavings from accumulating on the clamping parts, equipment guide rails, and transmission components. This reduces mechanical wear, lowers the risk of equipment jamming and increased transmission clearance, significantly extends the service life of the grinding machine, and protects operators from the hazards of metal dust, balancing production efficiency and operational safety.

[0024] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0025] like Figures 1 to 8 As shown, it illustrates a twist drill bit grinding machine of the present invention, including a grinding machine and its mechanical components 1. The grinding machine and its mechanical components 1 clamp the drill bit 2 to be ground at the clamping end. The grinding machine and its mechanical components 1 are provided with a clamping and fixing component 3 in the middle and an adsorption cleaning component 4 at the lower end of the clamping and fixing component 3. The clamping and fixing assembly 3 includes a clamping housing 301, a lower sliding connecting rail 302 fixedly connected to the lower end of the clamping housing 301, a rotating ring 303 rotatably connected inside the clamping housing 301, a connecting ring 304 fixedly connected inside the rotating ring 303, and a worm gear 305 fixedly connected to one end of the connecting ring 304.

[0026] By combining the grinding machine and its mechanical components 1, the drill bit to be ground 2, the clamping and fixing assembly 3, and the adsorption cleaning assembly 4, a complete working structure for grinding the twist drill bit is constructed. The clamping and fixing assembly 3 provides a stable clamping base for the drill bit to be ground 2. The adsorption cleaning assembly 4 can simultaneously process grinding debris, realizing integrated processing and cleaning operations. The clamping shell 301 serves as the core mounting carrier of the clamping and fixing assembly 3. The lower sliding connecting rail 302 fixed at its lower end also provides support for the position adjustment of the adsorption cleaning assembly 4. The linkage between the rotating ring 303 and the connecting ring 304 transmits power for subsequent clamping actions. The worm gear 305 is a key component for realizing power steering and deceleration, together ensuring the stable operation of the clamping structure.

[0027] like Figures 1 to 5 As shown, a servo motor 306 is fixedly connected inside the clamping housing 301, and a worm gear 307 is fixedly connected to the output end of the servo motor 306. The worm gear 307 is meshed with the worm wheel 305.

[0028] Power is provided by a servo motor 306 fixed inside the clamping housing 301. This, combined with the meshing transmission of a worm gear 307 and a worm wheel 305 fixed at its output end, converts the high-speed rotation of the servo motor 306 into the low-speed, stable rotation of the worm wheel 305. This achieves precise power transmission and, through the self-locking characteristics of the worm gear and worm wheel, prevents reverse loosening during clamping, ensuring the stability of the drill bit 2 being ground. For the servo motor 306, a Panasonic A6 series MHMF042L1U2M model is recommended. This model has a rated power of 400W, a rated speed of 3000rpm, and high-precision position control. It can precisely adjust the rotation angle via pulse signals to adapt to the clamping requirements of drill bits 2 of different diameters. For the worm gear 307 and worm wheel 305, precision transmission components with a module of 2 and a gear ratio of 1:20 are recommended to ensure no significant backlash during power transmission, further improving clamping accuracy.

[0029] like Figures 1 to 5 As shown, a driving ring 308 is fixedly connected to the other end of the connecting ring 304. A limiting ring 309 is provided inside the clamping housing 301. The limiting ring 309 is fixedly connected to the inner side wall of the clamping housing 301 through multiple fixing rods 310. Multiple clamping sliding blocks 311 are slidably connected inside the limiting ring 309. A driven rod 312 is fixedly connected to the rear end of each of the multiple clamping sliding blocks 311. The multiple driven rods 312 are slidably connected to the driving ring 308. A clamping piece 313 is fixedly connected to the end of each of the multiple clamping sliding blocks 311 that is close to each other.

[0030] Through the coordinated action of the driving ring 308 fixed at the other end of the connecting ring 304, the limiting ring 309 fixed inside the clamping housing 301 by the fixing rod 310, the clamping sliding block 311 slidably connected inside the limiting ring 309, the driven rod 312 fixed at the rear end of the clamping sliding block 311, and the clamping piece 313 fixed at the front end of the clamping sliding block 311, the rotational motion of the driving ring 308 is converted into the linear convergence motion of the clamping sliding block 311. The fixing rod 310 ensures that the limiting ring 309 is fixed in position, providing a support for the clamping sliding block 311. The stable sliding track and the driven rod 312 serve as the power transmission medium between the driving ring 308 and the clamping sliding block 311. Finally, through multiple sets of clamping plates 313, they move synchronously toward the center to achieve the centering and clamping of the drill bit 2 to be ground, preventing the drill bit 2 from shifting during the grinding process. The clamping plates 313 are recommended to be made of tungsten steel with a sandblasted surface to improve friction and ensure that they do not slip during clamping. The fixing rod 310 is made of 45 steel with a diameter of 8mm and its length is adapted to the inner diameter of the clamping shell 301 to ensure that the limiting ring 309 does not wobble after installation.

[0031] like Figures 6 to 7As shown, the adsorption cleaning component 4 includes a mounting sliding block 401 that is slidably connected inside the lower sliding connecting track 302. A connecting plate 402 is fixedly connected to the lower end of the mounting sliding block 401. An exhaust housing 403 is fixedly connected to the lower end of the connecting plate 402. An exhaust pipe 404 is connected to the middle of the exhaust housing 403. An exhaust fan 405 is installed inside the exhaust pipe 404.

[0032] An active debris adsorption structure is constructed by using an adsorption cleaning component 4, which consists of an installation sliding block 401 slidably connected to the lower sliding connecting track 302, a connecting plate 402 fixed at the lower end of the installation sliding block 401, an exhaust housing 403 fixed at the lower end of the connecting plate 402, an exhaust pipe 404 connected in the middle of the exhaust housing 403, and an exhaust fan 405 installed inside the exhaust pipe 404. The installation sliding block 401 can move flexibly along the lower sliding connecting track 302, allowing for on-demand adjustment of the position of the exhaust housing 403 to ensure it is always aligned with the debris. In the area where the grinding occurs, the exhaust fan 405 creates a negative pressure inside the exhaust housing 403, quickly drawing the metal shavings generated during grinding into the exhaust housing 403 to prevent shavings from splashing. For this area, the exhaust fan 405 is recommended to be an axial flow fan, model Delta AFB0624HH. This model has a rated voltage of 24V, a rated current of 0.3A, and an airflow of 12CFM. It features low noise and high air pressure, effectively adsorbing fine metal shavings. Simultaneously, its IP54 protection rating allows it to adapt to the dusty environment during grinding machine operation, extending its service life.

[0033] like Figures 6 to 7 As shown, a collection shell 406 is fixedly connected to the upper end of the connecting plate 402, an isolation net 407 is fixedly connected to the lower end of the collection shell 406, and multiple mounting shafts 408 are fixedly connected inside the collection shell 406. Multiple electromagnets 409 are fixedly connected to the middle of each of the multiple mounting shafts 408.

[0034] The system utilizes a collection housing 406 fixed to the upper end of the connecting plate 402, an isolation net 407 fixed to the lower end of the collection housing 406, a mounting shaft 408 fixed inside the collection housing 406, and an electromagnet 409 fixed in the middle of the mounting shaft 408 to achieve graded collection and filtration of inhaled debris. The isolation net 407 first blocks large particles of debris, preventing them from clogging the exhaust pipe 404. The electromagnet 409, when energized, generates magnetism, attracting fine metallic dust particles that pass through the isolation net 407, preventing dust from being discharged with the airflow and polluting the environment. 7. It is recommended to use 304 stainless steel material with a mesh count of 80 to ensure ventilation and effectively intercept debris larger than 0.18mm in diameter. For electromagnet 409, it is recommended to use suction cup type electromagnet XDA-20 / 15 model with a rated voltage of 24V and a suction force of 15N. Three electromagnets should be evenly installed on a single mounting shaft 408 to ensure that there are no dead corners for adsorption inside the collection shell 406. The mounting shaft 408 should be a 304 stainless steel rod with a diameter of 6mm and a length that matches the inner diameter of the collection shell 406 to ensure that the electromagnet 409 is installed stably.

[0035] like Figures 1 to 5 As shown, the driving ring 308 has multiple arc-shaped sliding holes in the middle that are slidably connected to the driven rod 312.

[0036] Multiple arc-shaped sliding holes in the middle of the drive ring 308 provide a sliding trajectory for the driven rod 312. When the drive ring 308 rotates, the arc-shaped sliding holes can convert the rotational motion into the radial thrust of the driven rod 312 through sliding cooperation with the driven rod 312. This ensures that multiple sets of driven rods 312 drive the clamping sliding block 311 to move synchronously, avoiding uneven clamping force on the clamping plate 313 due to transmission trajectory deviation. The arc of the arc-shaped sliding hole is recommended to be designed to be 60°, and the hole diameter is 0.2mm larger than the diameter of the driven rod 312. This ensures smooth sliding and avoids obvious shaking, further improving the synchronization of the clamping action.

[0037] like Figures 1 to 5 As shown, the center of the limiting ring 309 has multiple cross-shaped sliding holes that are slidably connected to the clamping sliding block 311.

[0038] Multiple cross-shaped sliding holes in the center of the limiting ring 309 precisely limit the movement direction of the clamping sliding block 311, preventing the clamping sliding block 311 from deflecting or getting stuck during sliding. This ensures that the clamping sliding block 311 always moves in a straight line along the radial direction, thereby ensuring that the clamping plate 313 can make uniform contact with the outer wall of the drill bit 2 to be ground. The width of the cross-shaped sliding hole is 0.1 mm larger than the width of the clamping sliding block 311, and the depth is 2 / 3 of the thickness of the limiting ring 309. This satisfies the sliding requirements while ensuring the structural strength of the limiting ring 309, preventing deformation after long-term use.

[0039] like Figures 6 to 7As shown, a rectangular hole is provided in the middle of the connecting plate 402.

[0040] like Figures 6 to 7 As shown, the lower end of the collection housing 406 is provided with an isolation hole for installation with the isolation net 407.

[0041] The isolation holes facilitate the installation of the isolation net 407.

[0042] like Figures 6 to 7 As shown, the collection housing 406 is connected to the exhaust housing 403 through a rectangular hole in the middle of the connecting plate 402.

[0043] By connecting the outer casing 406 and the rectangular hole in the middle of the connecting plate 402, the airflow inside the exhaust casing 403 can be completely introduced into the collection casing 406. This allows debris to be filtered by the isolation mesh 407 under negative pressure, and then attracted by the electromagnet 409, forming a dual cleaning process of filtration followed by suction. This prevents unfiltered debris from directly entering the exhaust pipe 404 and damaging the exhaust fan 405, while also ensuring thorough debris collection and reducing subsequent manual cleaning workload. The working principle and usage process of this utility model are as follows: First, the drill bit 2 to be ground is placed between the clamping end of the grinding machine and its mechanical components 1 and the clamping and fixing assembly 3. Then, the servo motor 306 inside the clamping housing 301 in the clamping and fixing assembly 3 is started. The output end of the servo motor 306 will drive the worm 307 to rotate. Since the worm 307 is meshed with the worm wheel 305 fixed at one end of the connecting ring 304, the rotation of the worm 307 will drive the worm wheel 305 to rotate synchronously, thereby driving the connecting ring 304 connected to the worm wheel 305 and the rotating ring 303 fixed on the outside of the connecting ring 304 to rotate inside the clamping housing 301. The drive ring 308, fixed at the other end of the connecting ring 304, rotates together with the connecting ring 304. The arc-shaped sliding hole in the middle of the drive ring 308 is slidably connected to the driven rod 312 fixed at the rear end of the clamping sliding block 311. When the drive ring 308 rotates, it generates a thrust on the driven rod 312 through the arc-shaped sliding hole, causing the driven rod 312 to drive the clamping sliding block 311 to slide within the cross-shaped sliding hole in the middle of the limiting ring 309. The limiting ring 309 is connected to the clamping housing 3 by multiple fixing rods 310. With the inner wall fixed and its position stable, multiple clamping sliding blocks 311 will synchronously converge towards the center along the cross-shaped sliding hole until they are close to each other. The clamping piece 313 fixed at one end is in close contact with the outer wall of the drill bit 2 to be ground, thereby achieving clamping and fixing of the drill bit 2 to be ground. Furthermore, by adjusting the speed of the servo motor 306, the transmission speed of the worm gear 307 and worm wheel 305 can be controlled, thereby adjusting the convergence range of the clamping sliding blocks 311 to adapt to drill bits 2 of different diameters and control the clamping force, thus completing the clamping of the drill bit 2 to be ground. Afterwards, the grinding machine and its mechanical components 1 begin to perform groove grinding operations on the drill bit 2 to be ground. Simultaneously, the exhaust fan 405 inside the exhaust pipe 404 of the adsorption cleaning assembly 4 is activated. When the exhaust fan 405 is working, it generates negative pressure inside the exhaust housing 403. Metal chips generated during the grinding process are sucked into the exhaust housing 403 under this negative pressure. Because the connecting plate 402 has a rectangular hole in the middle, and the collection housing 406 is connected to the exhaust housing 403 through this rectangular hole, the chips inside the exhaust housing 403... The debris enters the collection housing 406 fixed at the upper end of the connecting plate 402 through the rectangular hole. The isolation net 407 fixed at the lower end of the collection housing 406 filters the incoming debris, blocking large particles above the isolation net 407, while fine metal dust passes through the isolation net 407 and moves upward. At this time, the electromagnet 409 fixed in the middle of the multiple mounting shafts 408 fixed inside the collection housing 406 is energized and generates magnetism, which attracts fine metal dust to the surface of the electromagnet 409, thus realizing the collection and cleaning of grinding debris.If the cleaning range needs to be adjusted according to the grinding position of the drill bit 2, the mounting sliding block 401, which is slidably connected to the lower sliding connecting rail 302 in the adsorption cleaning component 4, can be pushed. The mounting sliding block 401 will drive the connecting plate 402 and the exhaust housing 403 and the collection housing 406 connected to the connecting plate 402 to move along the lower sliding connecting rail 302, so that the exhaust housing 403 is always aligned with the area where the debris is generated, ensuring the cleaning effect. After the grinding operation is completed, the servo motor 306 and the exhaust fan 405 are turned off. The servo motor 306 reverses to drive all components to reset, the clamping plate 313 releases the drill bit 2, and the processed drill bit is removed. At the same time, large particles of debris on the isolation mesh 407 inside the collection housing 406 can be cleaned, and the power supply to the electromagnet 409 is disconnected to clean the adsorbed fine dust, preparing for the next use.

[0044] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
