Description

Technical Field

[0001] The invention belongs to the technical field of drilling tools, and in particular relates to a high-efficiency chip removal and cooling device for a drill bit. Background Art

[0002] During the drilling process, there will be severe friction between the drill bit and the material being processed. This friction will quickly generate a large amount of heat, causing the drill bit temperature to rise sharply. Excessive temperature will have many negative effects on the performance and service life of the drill bit. Therefore, effective cooling of the drill bit has become a key link to ensure the smooth progress of the drilling operation, improve processing quality and reduce costs. Existing drill equipment still has the following defects in chip removal and cooling: In terms of chip removal, most traditional drill bits only rely on simple spiral chip grooves for chip removal. However, in the actual drilling process, especially when processing some materials with high viscosity or irregular chip shapes, the chips are easy to accumulate and entangle in the chip grooves, making it difficult to discharge smoothly. This will not only hinder the drill bit from continuing to drill and reduce drilling efficiency, but may also cause additional wear on the drill bit cutting edge, further affecting the drill bit life. In terms of cooling, the cooling methods adopted by some existing equipment are relatively simple and inefficient. Some equipment is cooled only by natural air cooling, which cannot quickly and effectively remove the large amount of heat generated during the drilling process, and the cooling effect is poor. Although other equipment uses coolant cooling, the circulation path of the coolant inside the equipment is unreasonably designed, the contact area between the coolant and the drill bit is small, and the residence time is short, and the heat cannot be efficiently absorbed and removed. It is difficult to meet the demand for efficient cooling of the drill bit, which in turn affects the drilling quality and the service life of the drill bit. In view of this, the present invention is specially proposed. Summary of the invention

[0017] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention but are not used to limit the scope of the present invention.

[0018] Example 1: Reference Figure 1-Figure 10 A drill bit efficient chip removal and cooling device comprises a mounting frame 103, and also comprises: a sliding frame 401 slidably connected to the mounting frame 103; a mounting plate 2, which is lifted and connected to the sliding frame 401, wherein a rotating sleeve 201 is rotatably connected to the mounting plate 2, and a drill bit 202 is detachably connected to the rotating sleeve 201, and a chip removal groove 3 is provided on the outer wall of the drill bit 202, and the chip removal groove 3 is spirally arranged, and a connected cooling cavity 301 is provided on the drill bit 202 and the rotating sleeve 201, and a spray hole 302 connected to the cooling cavity 301 is provided on the groove wall of the chip removal groove 3, and the spray hole 302 is located at a position of the chip removal groove 3 close to the drill blade, and the spray hole 302 is inclined upward; a cooling medium supply component is arranged on the mounting frame 103, and is used to transport cooling medium into the cooling cavity 301.

[0019] A screw rod 403 is rotatably connected to the mounting frame 103 . A guide groove 402 is provided on the mounting frame 103 . The sliding frame 401 is slidably connected in the guide groove 402 and is threadedly connected to the screw rod 403 . A handle 404 is fixedly connected to the screw rod 403 .

[0020] The hydraulic telescopic rod 4 is fixedly connected to the sliding frame 401 , and the mounting plate 2 is fixedly connected to the telescopic end of the hydraulic telescopic rod 4 .

[0021] One end of the rotating sleeve 201 passing through the upper end of the mounting plate 2 is fixedly connected to a gear 1 204 , a motor 205 is fixedly mounted on the mounting plate 2 , and a gear 2 206 meshing with the gear 1 204 is fixedly connected to the output end of the motor 205 .

[0022] The cooling medium supply component includes a liquid storage tank 1 and a liquid supply pump 303. The mounting frame 103 is fixedly connected to the liquid storage tank 1. The liquid supply pump 303 is fixedly connected to the mounting frame 103. The input end of the liquid supply pump 303 is connected to the liquid storage tank 1. A leakage plate 101 is fixedly installed on the upper end surface of the liquid storage tank 1. A liquid infusion tube 304 is fixedly connected to the output end of the liquid supply pump 303. One end of the liquid infusion tube 304 away from the liquid supply pump 303 is connected to the cooling chamber 301 through a rotary joint 305. The rotary joint 305 is arranged on one end of the rotating sleeve 201 that passes through the upper end of the mounting plate 2.

[0023] The cooling cavity 301 on the drill bit 202 is arranged in a spiral shape.

[0024] The liquid storage tank 1 also includes a filter screen 102 which is fixedly installed in the liquid storage tank 1 and is located below the liquid leakage plate 101 . Both sides of the liquid storage tank 1 are provided with cleaning ports which are flush with the surface of the filter screen 102 .

[0025] When in use, the workpiece to be processed is stably placed on the leakage plate 101. The leakage plate 101 not only provides a stable support platform for the workpiece, but also allows the coolant to pass smoothly during the subsequent drilling process and flow back to the liquid storage tank 1, thereby realizing the recycling of the coolant and saving resources. Then, the handle 404 on the screw 403 is turned, and the screw 403 rotates accordingly. Since the sliding frame 401 is threadedly connected to the screw 403 and slides in the guide groove 402, the rotational movement of the screw 403 is converted into the linear movement of the sliding frame 401, thereby driving the mounting plate 2 and the drill bit 202 to move in the lateral direction. The guide groove 402 plays a precise guiding role, ensuring the stability and accuracy of the movement of the sliding frame 401, so that the operator can easily and accurately align the drill bit 202 with the drilling position on the workpiece, thereby improving the positioning accuracy and efficiency of drilling; Then, the hydraulic telescopic rod 4 is started, and hydraulic oil is input into the hydraulic telescopic rod 4 to push its telescopic end to extend or retract, thereby driving the mounting plate 2 and the drill bit 202 to rise and fall. The hydraulic telescopic rod 4 can provide a stable and large driving force to achieve a smooth rise and fall of the mounting plate 2, and facilitate accurate adjustment of the height of the drill bit 202 to meet different drilling depth requirements and ensure the accuracy of the drilling depth; The motor 205 on the mounting plate 2 is turned on, and the output shaft of the motor 205 drives the second gear 206 to rotate. The power of the motor 205 is transmitted to the rotating sleeve 201 through the meshing transmission between the second gear 206 and the first gear 204 on the rotating sleeve 201, driving the drill bit 202 to rotate at a high speed. The gear transmission has the advantages of accurate transmission ratio, high transmission efficiency, and large transmission power, and can stably drive the drill bit 202 to rotate, ensuring the smooth progress of the drilling operation. At the same time, the rotation speed of the drill bit 202 can be adjusted by replacing gears with different numbers of teeth according to different drilling requirements, thereby improving the applicability of the equipment; The liquid supply pump 303 is started, and the liquid supply pump 303 extracts the coolant in the liquid storage tank 1 and delivers it to the rotary joint 305 through the liquid delivery tube 304. The rotary joint 305 is installed at one end of the rotating sleeve 201 that passes through the upper end of the mounting plate 2. It can ensure that the coolant can still smoothly enter the cooling cavity 301 during the rotation of the rotating sleeve 201. After the coolant enters the spirally arranged cooling cavity 301, it flows along the spiral channel, increasing the contact area and residence time with the drill bit 202, improving the cooling effect, and enabling it to more effectively remove the drilling Heat, reduce the drill edge temperature, improve the service life of the drill bit 202 and the drilling quality. Finally, the coolant is sprayed upward from the spray hole 302 on the wall of the chip groove 3 near the drill edge. On the one hand, the sprayed coolant directly cools the drill edge, reduces the heat generated during the drilling process, reduces tool wear, and extends the service life of the drill bit 202. On the other hand, the coolant produces an upward flushing force on the chips. With the spiral chip groove 3, the chips can be more effectively discharged from the drill hole, preventing the chips from clogging the chip groove 3, improving the chip removal efficiency, and thus improving the drilling quality. While the motor 205 drives the drill bit 202 to rotate and the liquid supply pump 303 delivers the coolant, the hydraulic telescopic rod 4 is operated again to gradually lower the drill bit 202 to start drilling the workpiece. During the drilling process, the operator can fine-tune the height of the drill bit 202 through the hydraulic telescopic rod 4 according to the actual situation to ensure that the drilling depth meets the requirements; The coolant and chips generated during the drilling process fall onto the leakage plate 101, and the coolant flows back into the liquid storage tank 1 through the holes on the leakage plate 101. In the liquid storage tank 1, the filter 102 located below the leakage plate 101 filters the refluxed coolant, intercepts the chips and other impurities therein, prevents the impurities from entering the liquid supply pump 303, avoids the blockage and wear of the liquid supply pump 303, and prolongs the service life of the liquid supply pump 303. At the same time, the cleanliness of the cooling medium is ensured, the cooling effect and the smooth flow of the liquid spray hole 302 are maintained, and the device can be ensured to operate continuously and stably. When the drilling operation is completed, first turn off the liquid supply pump 303 to stop the supply of coolant, then turn off the motor 205 to stop the rotation of the drill bit 202, and finally operate the hydraulic telescopic rod 4 to lift the drill bit 202 away from the workpiece, and then remove the processed workpiece from the leakage plate 101.

[0026] It should be noted that if there are a lot of impurities intercepted on the filter 102, the operator can use the cleaning ports on both sides of the liquid storage tank 1 that are flush with the surface of the filter 102 to clean the impurities on the filter 102 to ensure the filtering effect of the filter 102; The infusion tube 304 is a stretchable and shrinkable hose, so the infusion tube 304 will not interfere with the movement of the mounting plate 2 driven by the sliding frame 401.

[0027] Example 2: Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 8 , a drill bit efficient chip removal and cooling device, which is basically the same as Example 1, and further, an accordion sleeve 5 is fixedly connected to the mounting plate 2, the drill bit 202 is located in the accordion sleeve 5, and a plurality of dust hoods 501 are equidistantly arranged on the circumference of the upper end of the accordion sleeve 5, and a dust pump 502 and a filter box 503 are fixedly installed on the mounting frame 103, the input end of the dust pump 502 is connected to the filter box 503, and the filter box 503 is connected to the dust hood 501 through a dust pipe 504.

[0028] An activated carbon filter element 505 and a collecting frame 506 are inserted into the filter box 503. The collecting frame 506 is located below the activated carbon filter element 505. The end of the dust suction pump 502 connected to the filter box 503 is located above the activated carbon filter element 505. The end of the dust suction pipe 504 connected to the filter box 503 is located between the activated carbon filter element 505 and the collecting frame 506.

[0029] When the motor 205 is started to drive the drill bit 202 to rotate and start the drilling operation, the dust pump 502 is started. The dust pump 502 works to form a negative pressure in the filter box 503, which is transmitted to the multiple dust hoods 501 arranged at equal intervals on the upper end of the accordion sleeve 5 through the dust suction pipe 504, forming suction around the dust hoods 501. The design of the multiple dust hoods 501 can fully cover the area around the drill bit 202, effectively collecting chips and dust particles; The cooling medium supply component starts to work, and the coolant is sprayed out from the spray hole 302 to cool the drill blade and assist in chip removal. The coolant and chips may splash during the drilling process, so the accordion sleeve 5 can prevent them from splashing around, so that the working area can be kept relatively clean; The chips generated by drilling are quickly sucked into the dust collection pipe 504 under the suction of the dust collection hood 501, and the chips enter the filter box 503 along with the airflow. First, the larger particles of chips fall directly into the collection frame 506 due to gravity, which is convenient for centralized cleaning and reduces the burden on subsequent filtering components. The fine particles of chips continue to flow upward with the air and pass through the activated carbon filter element 505. Since the activated carbon filter element 505 has a strong adsorption effect, it can effectively filter and adsorb the fine particles in the air, further purifying the air. The purified clean air is discharged from the dust suction pump 502, thereby improving the working environment and protecting the respiratory health of the operator. After the drilling operation is completed, first turn off the motor 205 to stop the drill bit 202 from rotating, then turn off the vacuum pump 502 to stop the vacuum operation, then check the collection box 506. If there are a lot of chips in it, pull out the collection box 506 to clean the chips, and then regularly check the use of the activated carbon filter element 505. If its adsorption effect decreases, replace the activated carbon filter element 505 in time to ensure that it can still work efficiently the next time it is used.

[0030] It should be additionally explained that the dust suction tube 504 is a stretchable and contractible hose, so the dust suction tube 504 will not interfere with the movement of the installation plate 2 driven by the sliding frame 401.

[0031] Example 3: Reference Figure 5 , Figure 6 , Figure 7 , a drill bit efficient chip removal and cooling device, which is basically the same as Example 1, and further, the drill bit 202 is inserted into the rotating sleeve 201, a fastening ring is fixedly connected to the drill bit 202, and a locking ring 203 is threadedly connected to the lower end of the rotating sleeve 201, and one end of the locking ring 203 inserted into the rotating sleeve 201 is against the lower end surface of the fastening ring.

[0032] When in use, according to the material of the workpiece, drilling requirements and other factors, select a drill bit 202 of appropriate specifications, insert the drill bit 202 into the rotating sleeve 201, make the fastening ring on the drill bit 202 fit with the inner wall of the rotating sleeve 201, then tighten the locking ring 203 so that it abuts against the lower end surface of the fastening ring, and firmly fix the drill bit 202 on the rotating sleeve 201. When disassembling, rotate the locking ring 203 in the opposite direction to take out the drill bit 202; This detachable connection method is convenient and quick, and the drill bit 202 can be quickly replaced according to different processing tasks, which improves the versatility and processing efficiency of the equipment. At the same time, the reliable fixing method ensures the stability of the drill bit 202 during the drilling process, which is conducive to improving the accuracy and quality of drilling.
