Description

Technical Field

[0001] The utility model relates to the field of deep hole drills, in particular to a deep hole drill for preventing flying chips. Background Art

[0002] In the field of metal processing, deep hole drilling, as an important processing technology, is widely used in many industries such as aerospace, automobile manufacturing, and mold processing. However, in the process of deep hole drilling, due to characteristics such as large drilling depth, difficult chip removal, and large drilling force, technical problems such as flying chip splashing, coolant loss, and low drilling efficiency often occur.

[0003] During the drilling process of traditional deep hole drills, due to reasons such as large drilling force, high cutting temperature, and poor chip removal, the chips generated by drilling often splash into the surrounding environment. This not only pollutes the working environment but also may pose a threat to the safety of operators. In addition, the flying chips may adhere to the surface of the drilling tool or workpiece, affecting the machining accuracy and surface quality. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a deep hole drill for preventing flying chips, and solve the following technical problems: how to effectively prevent the flying chips generated during the drilling process from splashing, and how to improve the efficiency and stability of deep hole drilling.

[0005] In order to solve the problems existing in the prior art, the technical scheme adopted by the utility model is as follows:

[0006] A deep hole drill for preventing flying chips includes a drill shank, a drill pipe, a drill bit, and a support seat. One end of the drill shank is provided with a drill pipe, one end of the drill pipe is fixedly connected with a drill bit, a rotating plate is slidably connected to the outside of the drill pipe, a support seat is rotatably connected to the outside of the rotating plate, a protective cover is rotatably connected to the side of the support seat away from the drill shank, and a chip discharge port is opened at the bottom of the protective cover.

[0007] Preferably, mounting holes are symmetrically opened at the top of the support seat, and triangular pieces are symmetrically fixedly connected to the top of the support seat. The mounting holes facilitate the quick installation and fixation of the support seat, improving the work efficiency. The triangular pieces enhance the structural strength of the support seat, ensuring the stability and durability during the drilling process.

[0008] Preferably, rubber balls are evenly installed on one side of the support seat and the outside of the protective cover, and the rubber balls on one side of the support seat and the outside of the protective cover are arranged alternately. The alternating arrangement of the rubber balls increases the resistance to the rotation of the protective cover, preventing random rotation under non-human operation.

[0009] Preferably, a baffle is slidably inserted into the chip discharge port of the protective cover. The baffle allows users to flexibly control the opening and closing of the chip discharge port according to needs, which can not only maintain a smooth chip discharge channel during the drilling process but also close the chip discharge port when necessary to prevent chip splashing.

[0010] Preferably, grooves are provided at both the top and bottom of the baffle. The grooves facilitate the user's fingers to hold and operate the baffle, making it more labor-saving and stable when sliding the baffle to control the opening and closing of the chip discharge port.

[0011] Preferably, a hole that closely fits the shape of the drill pipe is provided at the center of the rotating plate. The close fit of the hole ensures a firm connection between the rotating plate and the drill pipe, reduces friction and wear caused by sliding connection, and at the same time allows the rotating plate to rotate freely when the drill pipe rotates, ensuring the smooth progress of the drilling operation.

[0012] Preferably, chip discharge grooves are provided on the surfaces of the drill pipe and the drill bit. The chip discharge grooves effectively promote the discharge of chips and coolant generated during the drilling process, reduce the drilling resistance, and improve the drilling efficiency.

[0013] Compared with the related art, the present utility model has the following beneficial effects:

[0014] 1. By equipping with a protective cover, the deep hole drill can form a closed or semi-closed space during the drilling process, effectively blocking the chips generated by drilling from splashing into the surrounding environment, protecting the safety of the operator, and at the same time maintaining the cleanliness of the working environment.

[0015] 2. The design of the baffle slidably inserted into the chip discharge port on the protective cover allows the user to flexibly control the opening and closing of the chip discharge port according to needs, improving the operation convenience. The chip discharge port design at the bottom of the protective cover also facilitates the rapid discharge of chips and coolant, avoiding the occurrence of blockage. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] In order to make the objectives, technical solutions and advantages of the present utility model clearer and more understandable, the present utility model will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0022] The anti-flying-chip deep-hole drill has a drill shank 1, a drill pipe 2, a drill edge 3 and a support base 4;

[0023] As Figure 1 shown, one end of the drill shank 1 is provided with a drill pipe 2, one end of the drill pipe 2 is fixedly connected with a drill edge 3, the outside of the drill pipe 2 is slidably connected with a rotating plate 5, the outside of the rotating plate 5 is rotatably connected with a support base 4, one side of the support base 4 away from the drill shank 1 is rotatably connected with a protective cover 6, and a chip discharge port 7 is opened at the bottom of the protective cover 6;

[0024] The drill shank 1 is firmly connected to the drill pipe 2, and the drill edge 3 is fixed at the end of the drill pipe 2, forming the basic drilling part. The rotating plate 5 is sleeved outside the drill pipe 2 by a sliding connection. This design allows the rotating plate 5 to rotate freely without hindering the movement of the drill pipe 2 during rotation for drilling. At the same time, the rotational connection between the rotating plate 5 and the support base 4 provides additional support stability for the drill body, reducing vibration and deviation;

[0025] The support base 4 is installed on the drilling platform to ensure stability. The protective cover 6 is rotatably connected to one side of the support base 4 away from the drill shank 1, and its position is directly opposite to the drilling area. The edge of the protective cover 6 is designed to fit closely with the drilling platform to form a closed space, effectively preventing the chips generated during the drilling process from splashing into the surrounding environment;

[0026] The chip discharge port 7 opened at the bottom of the protective cover 6 is the key channel for discharging chips and coolant. This design not only ensures smooth chip discharge during the drilling process but also avoids chip accumulation from affecting the drilling efficiency.

[0027] As Figure 1 shown, mounting holes 8 are symmetrically opened at the top of the support base 4, and triangular pieces 9 are symmetrically and fixedly connected to the top of the support base 4. The mounting holes 8 allow the support base 4 to be firmly installed on the drilling platform using bolts, screws or other fasteners, ensuring that it will not move or shake during the drilling process, thereby guaranteeing the accuracy and stability of the drilling operation;

[0028] The triangular pieces 9 increase the structural strength of the support base 4, making the support base 4 more stable when bearing the drilling force, reducing the possibility of vibration and deviation, and improving the accuracy and safety of the drilling operation.

[0029] As Figure 1As shown, rubber balls 10 are evenly installed on one side of the support base 4 and the outer side of the protective cover 6. The rubber balls 10 on one side of the support base 4 and the outer side of the protective cover 6 are arranged alternately. The alternately arranged rubber balls 10 hinder each other, increasing the resistance to the rotation of the protective cover 6, ensuring that the protective cover 6 will not rotate randomly under non-human operation, and maintaining the stable orientation of the chip discharge port 7.

[0030] As Figure 1 shown, a baffle 11 is slidably inserted into the chip discharge port 7 of the protective cover 6, allowing the user to manually pull the baffle 11 to control the opening and closing of the chip discharge port 7 as needed, facilitating the adjustment of the chip discharge rate or completely closing the chip discharge port 7 when necessary.

[0031] As Figure 1 shown, grooves 12 are provided at the top and bottom of the baffle 11. The design of the grooves 12 enhances the grip between the fingers and the baffle 11, making the operation more convenient.

[0032] As Figure 1 shown, a hole 13 that closely fits the shape of the drill pipe 2 is provided at the center of the rotating plate 5. The shape of the hole 13 closely fits the drill pipe 2, enabling the rotating plate 5 to be firmly sleeved outside the drill pipe 2. At the same time, when the drill pipe 2 rotates for drilling, the rotating plate 5 can rotate freely without affecting the drilling operation.

[0033] As Figure 1 shown, chip discharge grooves 14 are provided on the surfaces of the drill pipe 2 and the drill bit 3. The chip discharge grooves 14 provided on the surfaces of the drill pipe 2 and the drill bit 3 further facilitate the smooth discharge of debris, reduce the resistance during the drilling process, and improve the drilling efficiency.

[0034] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention.
