[0028] In machining, a hole with a ratio of hole depth to hole diameter greater than 5 is usually called a deep hole. In existing drilling and cutting tools, chip removal in deep holes is difficult. Due to the limited space in the deep hole, the cut material debris cannot be manually discharged and will accumulate in the hole, increasing the friction between the drilling and cutting tool and the material debris, exacerbating the wear of the drilling and cutting tool, reducing the service life of the drilling and cutting tool. Moreover, as the hole depth increases, the stiffness of the drill bit of the drilling and cutting tool decreases, increasing the risk of the drilling and cutting tool breaking. In addition, the material debris will also hinder the cutting of the drilling and cutting tool, reducing production efficiency. For this reason, this application proposes a cutting and chip removal device, aiming to improve the chip removal ability and stiffness of the cutting and chip removal device in deep holes, making the cutting and chip removal device not easily damaged due to difficult chip removal in deep holes, and improving the service life of the cutting and chip removal device.

[0029] Please refer to Figures 1 to 3 , a cutting and chip removal device proposed by an embodiment of the present utility model, which is applied to cutting and processing in deep holes, includes a driving member 300, a screw rod 100, and a sleeve 200. One end of the screw rod 100 is drivingly connected to the driving member 300, and the driving member 300 drives the screw rod 100 to rotate around the axis 120 of the screw rod 100. The screw rod 100 is provided with a helical groove 110, and the helical groove 110 extends helically along the axis 120. The sleeve 200 has a cavity 210, and the sleeve 200 is sleeved on the screw rod 100. In the length direction of the sleeve 200, the sleeve 200 includes a first cylinder section 220 close to the driving member 300 and a second cylinder section 230 connected to the first cylinder section 220. An opening 221 communicating with the cavity 210 is provided on the side surface of the second cylinder section 230 for exposing the screw rod 100.

[0030] Thus, please refer to Figures 4 to 5 again. The screw rod 100 exposed by the opening 221 is used to cut the material in the deep hole, and the generated material debris falls into the second cylinder section 230 through the opening 221 and is transported to the first cylinder section 220 along with the helical groove 110 during the rotation of the screw rod 100, so as to discharge the material debris from the deep hole. The first cylinder section 220 and the second cylinder section 230 reduce the leakage or splashing of the material debris, improve the chip removal ability of the cutting and chip removal device, make the material debris cut by the screw rod 100 not easily accumulate in the deep hole, weaken the wear of the material debris on the screw rod 100, and improve the service life of the screw rod 100. The sleeve 200 is sleeved on the outer surface of the screw rod 100, increasing the overall stiffness of the screw rod 100, making the screw rod 100 not easily bend or break in the deep hole, and reducing the contact friction between the screw rod 100 and other substances in the deep hole, further reducing the wear of the screw rod 100 and extending the service life of the screw rod 100.

[0031] Optionally, in an embodiment, at one end of the screw rod 100 facing the driving member 300, the helical groove 110 extends out of the cavity 210.

[0032] In this way, the spiral groove 110 is opened and extended outside the cavity 210, so that the material debris falling into the spiral groove 110 can be transported by the spiral groove 110 outside the cavity 210 under the rotation of the screw 100, ensuring that the material debris can be discharged from the cavity 210 in a timely and sufficient manner, and it is not easy to accumulate in the cavity 210, resulting in the rotation of the screw 100 being blocked, ensuring the stable operation of the cutting and chip removal device and improving the chip removal efficiency of the cutting and chip removal device.

[0033] Optionally, in another embodiment, the length of the spiral groove 110 can be set in various ways, and the spiral groove 110 can also be extended into the first cylinder section 220.

[0034] Optionally, in one embodiment, in the length direction of the sleeve 200, the sleeve 200 further includes a third cylinder section 240 connected to the second cylinder section 230. One end of the third cylinder section 240 is connected to the end of the second cylinder section 230 away from the first cylinder section 220, and the end of the third cylinder section 240 away from the second cylinder section 230 is used to close the cavity 210, and the end of the screw 100 away from the driving member 300 is disposed in the third cylinder section 240.

[0035] In this way, the third cylinder section 240 is provided to close the cavity 210 at the end of the screw 100 away from the driving member 300, so that the sleeve 200 encloses the screw 100 at the end away from the driving member 300, reducing the contact between the part of the screw 100 that does not participate in cutting the material and other positions in the deep hole, making it not easy for the end of the screw 100 away from the driving member 300 to collide or rub against the outside and be damaged, and improving the overall stiffness of the screw 100, making the screw 100 not easy to bend or break, and improving the service life of the screw 100.

[0036] Optionally, in another embodiment, the setting of the third cylinder section 240 can be omitted, and the second cylinder section 230 can be extended to cover the end of the screw 100 away from the driving member 300 without closing the cavity 210, reducing the development cost of the sleeve 200.

[0037] Optionally, in one embodiment, the length dimension of the third cylinder section 240 is configured between 5 mm and 15 mm.

[0038] Thus, the length dimension of the third cylinder section 240 is configured to be between 5 mm and 15 mm, so that the length dimension of the third cylinder section 240 is in a more appropriate range. When the length of the third cylinder section 240 is less than 5 mm, due to the relatively small length of the third cylinder section 240, the end of the screw 100 away from the driving member 300 may abut against the bottom of the third cylinder section 240, increasing the friction between the screw 100 and the third cylinder section 240. As a result, when the screw 100 rotates, it is obstructed by the third cylinder section 240, which is likely to cause damage to the sleeve 200 and the screw 100. When the length of the third cylinder section 240 is greater than 15 mm, due to the relatively large length of the third cylinder section 240, the overall length of the sleeve 200 is relatively large, reducing the overall rigidity of the sleeve 200 and increasing the development cost of the sleeve 200. Therefore, configuring the length dimension of the third cylinder section 240 between 5 mm and 15 mm, on the one hand, makes it difficult for the end of the screw 100 away from the driving member 300 to contact the third cylinder section 240 and increase the friction, and on the other hand, ensures the overall rigidity of the sleeve 200 and reduces the production cost of the sleeve 200.

[0039] Preferably, the length dimension of the third cylinder section 240 is configured to be 10 mm.

[0040] Optionally, in an embodiment, the cutting and chip removal device further includes a holding member 400 connected to the driving member 300.

[0041] Thus, by providing the holding member 400, it is convenient for the user to hold and control the cutting and chip removal device, facilitating the user's operation and improving the usability of the cutting and chip removal device.

[0042] Optionally, in an embodiment, the holding member 400 has two opposite ends, and the two opposite ends form an arched structure. One end of the holding member 400 is connected to the outside of the first cylinder section 220, and the other end is connected to the driving member 300.

[0043] Thus, by connecting one end of the holding member 400 to the first cylinder section 220, on the one hand, the orientation of the sleeve 200 can be controlled by controlling the holding member 400 to facilitate controlling the cutting direction and moving direction of the screw 100. On the other hand, by connecting one end of the holding member 400 to the first cylinder section 220, the connection and installation of the sleeve 200 are realized, enhancing the connection stability between the sleeve 200, the screw 100 and the driving member 300, and further improving the overall structural strength of the cutting and chip removal device.

[0044] Optionally, in an embodiment, in the length direction of the sleeve 200, the length dimension of the first cylinder section 220 is configured to be between 30 mm and 60 mm.

[0045] Thus, the length dimension of the first barrel section 220 is configured to be between 30 mm and 60 mm, so that the length dimension of the first barrel section 220 is within a more appropriate range. When the length of the first barrel section 220 is less than 30 mm, it may be due to the small length of the first barrel section 220, resulting in insufficient space for the installation of the holding member 400. When the length of the first barrel section 220 is greater than 60 mm, due to the large length of the first barrel section 220, the transportation distance of the material debris in the cavity 210 is long, and it is not easy to discharge the material debris from the cavity 210 in time, reducing the chip removal efficiency of the cutting and chip removal device, and resulting in a large overall length of the sleeve 200, reducing the overall rigidity of the sleeve 200, making the sleeve 200 prone to bending damage, and also increasing the development cost of the sleeve 200. Therefore, configuring the length dimension of the first barrel section 220 between 30 mm and 60 mm, on the one hand, shortens the transportation distance of the material debris, improves the chip removal efficiency of the material debris, and can provide sufficient space for the holding member 400 to be arranged. On the other hand, it ensures the overall rigidity of the sleeve 200 and reduces the production cost of the sleeve 200.

[0046] Preferably, the length dimension of the first barrel section 220 is configured to be 40 mm.

[0047] Optionally, in an embodiment, the length dimension of the second barrel section 230 is configured to be between 90 mm and 120 mm. In the length direction of the second barrel section 230, the size of the opening 221 is the same as the length dimension of the second barrel section 230.

[0048] Thus, the length dimension of the second barrel section 230 is configured to be between 90 mm and 120 mm, so that the length dimension of the second barrel section 230 is within a more appropriate range. When the length of the second barrel section 230 is less than 90 mm, it may be due to the small length of the second barrel section 230 and the small length dimension of the opening 221, resulting in a small cutting area of the screw 100, reducing the cutting efficiency of the material, and making it difficult for the material debris to fall into the cavity 210 through the opening 221 for transportation, reducing the chip removal capacity of the cutting and chip removal device. When the length of the second barrel section 230 is greater than 120 mm, due to the large length of the second barrel section 230, the transportation distance of the material debris is increased, reducing the chip removal efficiency of the cutting and chip removal device, and resulting in a large overall length of the sleeve 200, reducing the overall rigidity of the sleeve 200, making the sleeve 200 prone to bending damage, and also increasing the development cost of the sleeve 200. Therefore, configuring the length dimension of the second barrel section 230 between 90 mm and 120 mm, on the one hand, enables the screw 100 to have sufficient cutting area to efficiently cut the material, and enables the material debris to fully fall into the cavity 210 for transportation, reducing the accumulation of the material debris in the deep hole. On the other hand, it shortens the transportation distance of the material debris, improves the chip removal efficiency of the material debris, and ensures the overall rigidity of the sleeve 200 and reduces the production cost of the sleeve 200.

[0049] Preferably, the length dimension of the second cylinder section 230 is configured to be 100 mm.

[0050] Optionally, in an embodiment, the materials of the sleeve 200 and the screw 100 are both configured to be high-strength steel.

[0051] In this way, the sleeve 200 and the screw 100 are made of high-strength steel, so that the screw 100 and the sleeve 200 have relatively high strength, and the screw 100 is not likely to curl or break during the rotary cutting of materials. At the same time, the sleeve 200 is not likely to be damaged by colliding with materials or other objects in the deep hole, enabling the cutting and chip removal device to adapt to cutting materials with relatively high hardness and improving the service life of the cutting and chip removal device.

[0052] Optionally, in an embodiment, the ratio of the length of the sleeve 200 to the cylinder diameter is set between 20 and 35.

[0053] In this way, the ratio of the length of the sleeve 200 to the cylinder diameter is set between 20 and 35, and the sleeve 200 can be placed in a narrow deep hole, enabling the cutting and chip removal device to adapt to cutting and chip removal in deep holes with a larger hole depth-to-diameter ratio, and increasing the applicable range of the cutting and chip removal device.

[0054] Preferably, the ratio of the length of the sleeve 200 to the cylinder diameter is set at 25.

[0055] The embodiment of the present invention further provides a drilling processing system, including the aforementioned cutting and chip removal device. The specific structure of the photovoltaic solder ribbon refers to the above embodiments.

[0056] It can be understood that those skilled in the art can, under the guidance of the above embodiments, combine various implementation manners in the above embodiments to obtain technical solutions of various implementation manners.

[0057] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention.
