These materials are prone to cracks or breakage during drilling due to their high hardness and low toughness.

[0003] In the prior art, when processing hard and brittle product materials, due to the high hardness of hard and brittle materials, the drill bit of a traditional impact drill is prone to wear and even chipping during the processing, resulting in a shortened drill tool life, the need for frequent replacement of the drill tool, and increased processing costs; secondly, processing hard and brittle materials will generate a large amount of fine chips, and traditional impact drills have poor chip removal, and the chips are easily accumulated in the processing area, causing increased processing resistance and affecting processing efficiency; in addition, the working mode of traditional impact drills is relatively single, and it is difficult to achieve independent control and rapid switching of the rotation function and the impact function, and it is difficult to adapt to the special requirements of different processes in the processing of hard and brittle materials, resulting in insufficient processing accuracy and causing quality problems such as surface cracks, chipping or fragmentation of the workpiece.

[0041] In order to make the purpose, features and advantages of the present invention more obvious and easy to understand, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described below are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0042] In the description of the present invention, it should be understood that the terms "upper", "lower", "top", "bottom", "inside", "outside" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation of the present invention. It should be noted that when a component is considered to be "connected" to another component, it may be directly connected to the other component or there may be a centrally arranged component at the same time.

[0043] The technical solution of the present invention is further described below with reference to the accompanying drawings and through specific implementation methods.

[0044] like Figures 1 to 7 As shown, the embodiment of the present invention provides a high-performance impact drill for processing hard and brittle product materials, including an impact drill bit 1, a housing 2, a rotating sleeve 3, a driving motor 4, an impact mechanism 5, a rotating mechanism 6 and a heating coil 7;

[0045] The shell 2 has a first cavity 21 and a second cavity 22 inside. The first cavity 21 is connected to the second cavity 22 and is vertically arranged. The rotating sleeve 3 is located in the first cavity 21. The impact drill bit 1 is connected to the rotating sleeve 3 by a key, and the impact drill bit 1 can slide along the extension direction of the rotating sleeve 3. The first cavity 21 can provide a closed working space for the rotating sleeve 3 and the impact drill bit 1, while the second cavity 22 is used to accommodate a driving device and a transmission mechanism. The impact drill bit 1 is connected to the rotating sleeve 3 by a key, so that the impact drill bit 1 and the rotating sleeve 3 can rotate synchronously. The impact drill bit 1 can slide along the extension direction of the rotating sleeve 3, so that the impact drill bit 1 can move freely when it is acted upon by the impact mechanism 5, thereby achieving intermittent impact action.

[0046] The driving motor 4 is arranged in the second cavity 22, and a gear shaft 41 is arranged at the output end of the driving motor 4. The gear shaft 41 is connected to the rotating mechanism 6 and the impact mechanism 5 at the same time. The rotating mechanism 6 is connected to the rotating sleeve 3 to drive the rotating sleeve 3 to rotate. The impact mechanism 5 partially extends into the rotating sleeve 3, and the impact mechanism 5 is used to intermittently impact the impact drill bit 1 in the rotating sleeve 3. The driving motor 4 is arranged in the second cavity 22, and a gear shaft 41 is arranged at the output end thereof. The gear shaft 41 serves as a core power transmission component and is connected to the rotating sleeve 3. The rotating mechanism 6 and the impact mechanism 5 are connected at the same time, and the rotational power of the driving motor 4 can be distributed to the two functional modules, so that the rotation and impact movements are coordinated; specifically, the rotating mechanism 6 is connected to the rotating sleeve 3, and the rotational power of the driving motor 4 can be transmitted to the rotating sleeve 3, so that the rotating sleeve 3 drives the impact drill bit 1 to rotate at a high speed, thereby producing a drilling effect during the processing; at the same time, the impact mechanism 5 partially extends into the interior of the rotating sleeve 3, directly acting on the impact drill bit 1, and converts the rotational power of the driving motor 4 into an impact movement along the axial direction of the impact drill bit 1 through periodic impact force. When the impact drill is used to process hard and brittle products, at the beginning of drilling, the rotating mechanism 6 works alone and slowly contacts the surface of the workpiece through rotating cutting. This gentle processing method can effectively avoid cracks or edge collapse on the workpiece surface caused by premature intervention of impact force, and at the same time provide a smooth and stable cutting reference for subsequent processing; when the drilling reaches a certain depth, the impact mechanism 5 starts to move. At this time, the material on the surface of the workpiece has been preliminarily removed, and the drilling pressure is gradually transferred to the internal material. The impact mechanism 5 can cooperate with the rotating mechanism 6 through periodic impact force to quickly remove the hard and brittle materials in the form of crushing during deep processing. This staged processing mode can not only effectively protect the integrity and processing quality of the workpiece surface, but also improve the processing efficiency of hard and brittle materials.

[0047] like Figure 7As shown, the impact drill bit 1 includes a drill rod portion 11 and a drill portion 12 connected to the drill rod portion 11, and the heating coil 7 is wound along the extension direction of the drill rod portion 11, and the heating coil 7 is used to heat the impact drill bit 1; for hard and brittle materials, the heated impact drill bit 1 can reduce the brittleness of the material in the cutting area, and transform the hard and brittle material from a high hardness and high brittleness state to a slightly ductile state, thereby reducing the processing resistance. In this way, the cracks and edge collapse caused by excessive local stress concentration can be reduced.

[0048] The drill head 12 is provided with three drill blades 121 arranged at intervals along the circumferential direction. The drill blades 121 are arranged spirally along the extension direction of the drill head 12. A chip removal channel 122 is formed between two adjacent drill blades 121. The chip removal channel 122 is used to remove the debris generated when the drill blade 121 drills the processing surface. During the processing, the three drill blades 121 arranged at intervals can effectively disperse the processing load during cutting, so that the cutting force of each drill blade 121 is evenly distributed, avoiding the chipping phenomenon caused by excessive force on a single drill blade 121; in the processing of hard and brittle materials, the accumulation of debris will increase the drilling resistance, thereby affecting the processing efficiency. Through the cooperation of the spiral drill blade 121 and the chip removal channel 122, the debris can be quickly discharged from the processing area, ensuring the smooth progress of the drilling process.

[0049] like Figure 2 and Figure 3 As shown, further, the rotating mechanism 6 includes a first gear 61, a rotating shaft 62, a bevel gear 63 and a gear plate 64. The first gear 61 is rotatably connected to the second cavity 22 and is meshed with the gear shaft 41. The first gear 61 is connected to the bevel gear 63 through the rotating shaft 62. The gear plate 64 is sleeved on the rotating sleeve 3. The bevel gear 63 is meshed with the gear plate 64. The gear plate 64 is used to drive the impact drill bit 1 in the rotating sleeve 3 to rotate when meshing and rotating. During the machining process, the output end of the driving motor 4 transmits power to the first gear 61 through the gear shaft 41. The first gear 61 can rotate freely in the second cavity 22 and transmit power to the rotating shaft 62. The rotating shaft 62 is connected to the bevel gear 63 as an intermediate transmission component, and can drive the gear plate 64 meshing with the bevel gear 63 to rotate. When the gear plate 64 rotates, it can drive the rotating sleeve 3 to rotate synchronously. The impact drill bit 1 is connected to the rotating sleeve 3 through a key connection, thereby realizing the rotary drilling action of the impact drill bit 1.

[0050] like Figure 2 and Figure 3As shown, further, the impact mechanism 5 includes a second gear 51, a rotating seat 52, a crank swing arm 53 and an impact head 54. The second gear 51 is rotatably connected to the second cavity 22 and is meshingly connected to the gear shaft 41. The second gear 51 is detachably connected to the rotating seat 52. The gear shaft 41 drives the rotating seat 52 to rotate through the second gear 51. One end of the crank swing arm 53 is eccentrically connected to the top of the rotating seat 52, and the other end of the crank swing arm 53 is connected to the impact head 54. The impact head 54 is located in the rotating sleeve 3. The crank swing arm 53 is used to convert the rotational motion of the rotating seat 52 into linear motion, and drive the impact head 54 to push the impact drill bit 1 in the rotating sleeve 3 to move outward. During the processing, the gear shaft 41 serves as a power input shaft, and can drive the rotating seat 52 to rotate synchronously through the second gear 51. The top of the rotating seat 52 is connected to one end of the crank swing arm 53 through an eccentric point. In this way, the rotational motion of the rotating seat 52 can be converted into periodic linear motion through the crank swing arm 53. The other end of the crank swing arm 53 is connected to the impact head 54, thereby pushing the impact drill bit 1 to move outward periodically through the impact head 54 to apply intermittent impact force to the processed material.

[0051] like Figure 4 As shown, further, it also includes a rotation separation component 8, which is connected to the gear plate 64 to drive the gear plate 64 to engage or separate with the bevel gear 63. The rotation separation component 8 includes a first knob 81 and a first lever 82. The first knob 81 is arranged outside the shell 2, and the first lever 82 is eccentrically connected to the bottom of the first knob 81. The first knob 81 is used to drive the first lever 82 to rotate. The outer wall of the rotating sleeve 3 is provided with a first slide groove 31, and the inner wall of the gear plate 64 is connected to the first slide groove 31 by a key. The gear plate 64 can slide along the side wall of the rotating sleeve 3, and the middle part of the gear plate 64 is provided with an annular groove 640. The first lever 82 is located in the annular groove 640. When rotating, the first lever 82 abuts against the side wall of the annular groove 640 to apply a thrust to the gear plate 64 to engage or separate with the gear shaft 41. In the meshing state, the gear plate 64 drives the rotating sleeve 3 to rotate together through the key connection, thereby transmitting the power of the rotating mechanism 6 to the impact drill bit 1 to achieve synchronous rotational cutting; when the gear plate 64 moves to the separation position along the first slide groove 31 under the action of the first lever 82, the meshing of the gear plate 64 and the bevel gear 63 is disconnected. At this time, the rotating sleeve 3 and the impact drill bit 1 stop rotating, and the processing mode is switched to a single impact mode to avoid unnecessary damage to the workpiece surface or special structure caused by rotational cutting.

[0052] like Figure 5 and Figure 6As shown, further, an impact separation component 9 is also included, and the impact separation component 9 is connected to the rotating seat 52 to drive the rotating seat 52 to connect or separate with the second gear 51. The impact separation component 9 includes a second knob 91, a second lever 92, a push column 93 and a clamping key 94. The top of the driving motor 4 is provided with an end cover 40, and the end cover 40 is provided with a receiving sleeve 401. A support seat 402 is provided inside the receiving sleeve 401. The cross-sectional area of ​​the support seat 402 is smaller than the cross-sectional area of ​​the receiving sleeve 401. The support seat 402 is used to support the push column 93, and the push column 93 is partially suspended and exposed on the support seat 402. The second knob 91 is provided on the At the side end of the shell 2, the second lever 92 is eccentrically connected to the second knob 91, the second lever 92 extends into the receiving sleeve 401, and the end of the second lever 92 abuts against the push column 93, the second lever 92 is used to drive the push column 93 to move up and down as the second knob 91 rotates, the interior of the rotating seat 52 is hollow, and waist-shaped grooves 520 are provided on both sides of the rotating seat 52, the snap-in key 94 is located in the waist-shaped groove 520, and the interior of the second gear 51 is provided with a snap-in groove 510 that is positioned and connected to the snap-in key 94, the snap-in key 94 is used to snap into or separate from the snap-in groove 510 as the push column 93 moves up and down. When the push column 93 moves upward under the action of the second lever 92, the engaging key 94 rises accordingly and is disconnected from the engaging slot 510 of the second gear 51, disconnecting the power transmission between the rotating seat 52 and the impact mechanism 5, so that the impact mechanism 5 stops working; on the contrary, when the second lever 92 deviates downward under the rotation of the second knob 91, the push column 93 abuts against the support seat 402 under the action of gravity, and the engaging key 94 is re-embedded into the engaging slot 510 of the second gear 51, thereby realizing the connection of the impact mechanism 5. At this time, the rotating seat 52 can receive the power transmission from the second gear 51, thereby driving the impact head 54 to perform periodic impact action. With such a setting, the activation or separation of the impact mechanism 5 can be accurately controlled, and when processing hard and brittle materials, unnecessary impact can be effectively avoided to cause damage to the workpiece surface; specifically, in the initial stage of processing, the impact function can be turned off, and only rotary drilling can be enabled to protect the workpiece surface; after the material removal enters a stable stage, the impact function can be turned on to improve the drilling efficiency of the material.

[0053] like Figure 4 As shown, further, the inner wall of the rotating sleeve 3 is provided with a second slide groove 32, and the outer wall of the impact drill bit 1 is connected to the second slide groove 32 by a key. Such an arrangement enables the impact mechanism 5 to push the impact drill bit 1 to move outward along the second slide groove 32 when working.

[0054] like Figure 7As shown, further, a chip guide groove 123 is provided on the end surface of the drill head 12, and the chip guide groove 123 is arranged between two adjacent drill blades 121, and the chip guide groove 123 gradually tilts downward from the inside to the outside to form a slope structure. During the processing, a large amount of fine chips will be generated when the drill blade 121 cuts hard and brittle materials, and these chips will accumulate in the processing area to increase the cutting resistance. The chip guide groove 123 is located between adjacent drill blades 121, and a natural chip removal passage is formed through its inclined slope structure, so that the chips generated by cutting are discharged into the chip removal channel 122 along the slope direction under the action of the drilling force.

[0055] like Figure 3 As shown, further, the impact mechanism 5 also includes an elastic push column 55, which is arranged in the rotating sleeve 3 between the impact head 54 and the impact drill bit 1. The elastic push column 55 can play a buffering role, and the elastic push column 55 can absorb part of the force applied by the impact head 54 and gradually release it to the impact drill bit 1, effectively avoiding the phenomenon of workpiece fragmentation caused by the impact drill bit 1 due to instantaneous high-intensity impact.

[0056] Furthermore, the impact drill bit 1 is made of cemented carbide, and the surface of the impact drill bit 1 is coated with a diamond coating. During the processing, the cemented carbide has high hardness and high compressive resistance, so that the impact drill bit 1 can withstand the high cutting force and impact force generated when processing hard and brittle materials without chipping, and the diamond coating provides the impact drill bit 1 with extremely high surface hardness and wear resistance, and the diamond coating has an extremely low friction coefficient, so that the impact drill bit 1 reduces the processing resistance when drilling hard and brittle materials, avoids cracks or fragments of hard and brittle materials during drilling, and effectively improves the performance of the impact drill.

Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some of the technical features thereof may be replaced by equivalents.
