Description

Technical Field

[0001] This utility model relates to the field of gun-type deep hole drilling technology, specifically a gun-type deep hole drill with adjustable guide and replaceable cutting blades. Background Technology

[0002] Gun drills are high-efficiency, externally chip-removing tools specifically designed for deep hole machining. While a traditional deep hole machining tool, gun drills have undergone continuous technological updates and improvements in recent years, resulting in new high-performance deep hole drilling tools such as indexable gun drills, which use inserts to replace the cutting edge and guide section of traditional gun drills.

[0003] The drill bit portion of the new high-performance deep hole drilling tool consists of indexable cutting tools and guide bars. The cutting tools are fixed to the drill body by a clamping device, while the guide bars guide the drill bit forward and maintain the straightness of the hole. The cutting tools are generally made of high-performance materials such as cemented carbide and ceramics, possessing excellent wear resistance and hardness. The drill rod is typically made of high-strength alloy steel to ensure sufficient rigidity and strength, preventing deformation or vibration during machining.

[0004] Existing high-performance deep hole drilling tools have demonstrated numerous significant advantages in practical applications. When the cutting tools wear out, they can be quickly replaced with new ones, eliminating the need for extensive tool resharpening. This greatly reduces downtime, significantly improving the continuity and stability of machining, making them particularly suitable for mass production scenarios and effectively enhancing overall production efficiency.

[0005] However, there is a problem that cannot be ignored during the use of this drill bit. Because the cutting edge of the blade is usually facing outwards during installation, workers are easily cut by the sharp blade when changing the blade. This undoubtedly increases the risk of disassembling the blade and poses a certain threat to the personal safety of the workers, which may affect the smooth progress of production. Summary of the Invention

[0006] The purpose of this invention is to provide a gun-type deep hole drill with adjustable guide and replaceable cutting blades to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A gun-type deep hole drill with adjustable guide and replaceable cutting blades includes a drill body and cutting blades. The drill body is characterized by having a mounting groove adapted to the cutting blades, a guide seat being rotatably disposed in the mounting groove, and the cutting blades being fixed to the guide seat by bolts.

[0009] The drill body has a cavity, and an adjustment component is installed in the cavity. The adjustment component is connected to the guide seat. When the adjustment component is running, the guide seat will first drive the cutting tool to move out of the mounting slot, and then drive the cutting tool to rotate at a certain angle.

[0010] The drill body has a disassembly hole, which is connected to the cavity.

[0011] As a further embodiment of this utility model:

[0012] The adjustment assembly includes a drive gear disk and a driven rotary disk that cooperates with the drive gear disk. When the drive gear disk rotates, the driven rotary disk will first remain stationary and then follow the rotation.

[0013] The cavity is provided with a cylindrical seat and a rotating rod, the driving gear disk is rotatably mounted on the cylindrical seat, and the driven disk is coaxially mounted on the rotating rod.

[0014] As a further improvement of this utility model:

[0015] A sleeve is coaxially provided on the active gear disk, and a sliding groove is formed in the cavity along the central axis of the active gear disk, and a sliding rod is slidably arranged in the sliding groove;

[0016] One end of the slide rod is provided with a rotating shaft, and the drive gear and the sleeve are coaxially and movably sleeved on the outside of the rotating shaft.

[0017] As a further improvement of this utility model:

[0018] The outer wall of the rotating shaft is provided with a spiral groove along its length, and the sleeve is fitted with rolling balls, which are also fitted with rolling balls in the spiral groove.

[0019] As a further improvement of this utility model:

[0020] A rotating column is coaxially provided at one end of the guide seat. The rotating column extends into the cavity. A limiting plate is provided on the outer wall of the rotating column. A push rod is provided on the outer wall of the rotating shaft. One end of the push rod is slidably engaged with the rotating column, and one end of the push rod abuts against the side of the limiting plate away from the guide seat.

[0021] A first spring is fitted on the outer wall of the rotating column, and the two ends of the first spring abut against the side of the limiting plate near the guide seat and the inner wall of the cavity, respectively.

[0022] As a further improvement of this utility model:

[0023] A first gear is coaxially arranged on the outer wall of the rotating rod, and a second gear is coaxially arranged on the outer wall of the rotating column;

[0024] The first gear and the second gear mesh with each other, and the thickness of the second gear is greater than the thickness of the first gear.

[0025] As a further improvement of this utility model:

[0026] The adjustment assembly also includes a guide plate and a toothed plate. The guide plate is disposed on the inner side wall of the cavity, and the toothed plate and the active toothed disc mesh with each other.

[0027] A T-shaped groove is formed on one side wall of the guide plate along its length, and a T-shaped block is provided on one side wall of the toothed plate. The T-shaped block is located in the T-shaped groove and is slidably engaged.

[0028] A second spring is installed inside the T-shaped groove. The two ends of the second spring abut against the inner sidewalls of the T-shaped block and the T-shaped groove, respectively. The disassembly hole corresponds to the position of the toothed plate.

[0029] Compared with the prior art, the beneficial effects of this utility model are:

[0030] The cutting tool is fixed to a guide seat within the mounting groove using bolts, while the guide seat can rotate freely within the mounting groove. The combined action of the bolts and the guide seat prevents the cutting tool from detaching from the mounting groove and precisely limits its movement, completely eliminating the possibility of rotation and providing stability for drilling operations.

[0031] When the blade needs to be replaced, this solution employs a clever and safe disassembly mechanism. First, a specialized tool is precisely inserted into the cavity through the disassembly hole, engaging tightly with the adjustment component within the cavity. As the adjustment component is activated, the guide seat first moves the blade out of the mounting slot. Then, the guide seat continues to rotate the blade at a certain angle, ensuring the sharp edge of the blade safely faces inwards towards the mounting slot, effectively avoiding the risk of cuts from an exposed blade. Finally, by loosening the bolt, the blade can be removed from the guide seat.

[0032] This disassembly method not only avoids the risk of workers being accidentally cut by the blade during the disassembly process, effectively reducing the risk of disassembly operations, but also simplifies the blade replacement process, making blade replacement more efficient and convenient. This provides a guarantee for high-intensity processing scenarios such as mass production and improves overall production efficiency. Attached Figure Description

[0043] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0044] Furthermore, the elements in this invention are referred to as being "fixed to" or "set on" another element, which may be directly on the other element or may also include an intervening element. When an element is considered to be "connected" to another element, it may be directly connected to the other element or may also include an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementation.

[0045] Please see Figures 1-9 In this embodiment of the utility model, a gun-type deep hole drill with adjustable guide for disassembling and replacing blades includes a drill body 1 and a blade 2. The drill body 1 is provided with an installation groove 101 adapted to the blade 2. A guide seat 3 is rotatably disposed in the installation groove 101. The blade 2 is fixed to the guide seat 3 by bolts 4.

[0046] The drill body 1 has a cavity 102, and an adjustment component is provided in the cavity 102. The adjustment component is connected to the guide seat 3. When the adjustment component is running, the guide seat 3 will first drive the blade 2 to move out of the mounting groove 101, and then drive the blade 2 to rotate at a certain angle.

[0047] The drill body 1 has a disassembly hole 103, which is connected to the cavity 102.

[0048] In this design, bolts 4 are used to fix the cutting blade 2 to the guide seat 3 inside the mounting groove 101, while the guide seat 3 can rotate flexibly within the mounting groove 101. With the synergistic effect of bolts 4 and guide seat 3, the cutting blade 2 cannot be dislodged from the mounting groove 101 and is precisely limited by the mounting groove 101, completely eliminating the possibility of rotation of the cutting blade 2 and providing stability for drilling operations.

[0049] When it is necessary to replace blade 2, this solution employs a clever and safe disassembly mechanism. First, a specialized tool is precisely inserted into cavity 102 through disassembly hole 103, engaging tightly with the adjustment component within cavity 102. As the adjustment component is activated, guide seat 3 first moves blade 2 out of mounting slot 101. Then, guide seat 3 continues to rotate blade 2 at a certain angle, ensuring its sharp edge safely faces the inside of mounting slot 101, effectively avoiding the risk of cuts from an exposed blade. Finally, by loosening bolt 4, blade 2 can be removed from guide seat 3.

[0050] The end of the drill body 1 is configured as a detachable end. Before assembly, the entire adjustment assembly is first installed into the cavity 102, and then the end is fixedly connected to the drill body 1.

[0051] As a further embodiment of this utility model, the adjustment component includes an active gear disk 5 and a driven rotary disk 6 that cooperates with the active gear disk 5. When the active gear disk 5 rotates, the driven rotary disk 6 will first remain stationary and then follow the rotation.

[0052] The cavity 102 is provided with a cylindrical base 7 and a rotating rod 8, which are rotatably mounted thereon. The driving gear disk 5 is rotatably mounted on the cylindrical base 7, and the driven rotating disk 6 is coaxially mounted on the rotating rod 8.

[0053] In this embodiment, since the active gear disk 5 and the driven turntable 6 cooperate with each other, when the active gear disk 5 rotates, the driven turntable 6 will first remain stationary and then follow the rotation. The active gear disk 5 and the driven turntable 6 together form the Maltese cross movement structure.

[0054] Since the driving gear 5 is rotatably mounted on the cylinder base 7 and the driven turntable 6 is coaxially mounted on the rotating rod 8, when the driving gear 5 drives the driven turntable 6 to rotate, the rotating rod 8 will also rotate accordingly.

[0055] As a further embodiment of this utility model, a sleeve 9 is coaxially provided on the active gear disk 5, and a sliding groove 104 is provided in the cavity 102 along the central axis of the active gear disk 5, and a sliding rod 10 is slidably provided in the sliding groove 104.

[0056] One end of the slide bar 10 is provided with a rotating shaft 11, and the drive gear 5 and the sleeve 9 are coaxially and movably sleeved on the outside of the rotating shaft 11.

[0057] In this embodiment, since the slide rod 10 is slidably disposed in the slide groove 104 opened along the central axis of the active gear disk 5, and one end of the slide rod 10 is provided with a rotating shaft 11, the active gear disk 5 and the sleeve 9 are coaxially and movably sleeved on the outside of the rotating shaft 11. Therefore, the rotating shaft 11 can only slide along the central axis of the active gear disk 5 and cannot rotate; wherein, both the slide groove 104 and the slide rod 10 are set as rectangles.

[0058] As a further embodiment of this utility model, the outer wall of the rotating shaft 11 is provided with a spiral groove 1101 along its length direction, and the sleeve 9 is fitted with a ball bearing 12, which is also fitted with the spiral groove 1101.

[0059] In this embodiment, since the sleeve 9 is fitted with rolling balls 12 inside, and the rolling balls 12 are also fitted with rolling balls in the spiral groove 1101 opened along the length direction of the outer wall of the rotating shaft 11, when the active gear disk 5 drives the sleeve 9 to rotate, the rotating shaft 11 will slide along the central axis of the active gear disk 5.

[0060] As a further embodiment of this utility model, a rotating column 13 is coaxially provided at one end of the guide seat 3. The rotating column 13 extends into the cavity 102. A limiting plate 14 is provided on the outer wall of the rotating column 13. A push rod 15 is provided on the outer wall of the rotating shaft 11. One end of the push rod 15 is slidably engaged with the rotating column 13, and one end of the push rod 15 abuts against the side of the limiting plate 14 away from the guide seat 3.

[0061] A first spring 16 is sleeved on the outer wall of the rotating column 13. The two ends of the first spring 16 abut against the side of the limiting plate 14 near the guide seat 3 and the inner wall of the cavity 102, respectively.

[0062] In this embodiment, since a rotating post 13 is coaxially provided at one end of the guide seat 3, and the rotating post 13 extends into the cavity 102, a limiting plate 14 is provided on the outer wall of the rotating post 13, and the two ends of the first spring 16 abut against the side of the limiting plate 14 near the guide seat 3 and the inner wall of the cavity 102 respectively, under the action of the first spring 16, the guide seat 3 will always have the tendency to move into the mounting groove 101, so that the blade 2 is always located in the mounting groove 101;

[0063] Furthermore, since the outer wall of the rotating shaft 11 is provided with a push rod 15, one end of the push rod 15 is slidably engaged with the rotating column 13, and one end of the push rod 15 abuts against the side of the limiting plate 14 away from the guide seat 3, when the rotating shaft 11 slides along the central axis of the active gear disk 5, the push rod 15 will drive the guide seat 3 to slide along the central axis of the active gear disk 5 through the limiting plate 14 and the rotating column 13, thereby causing the blade 2 to move out of the mounting groove 101.

[0064] As a further embodiment of this utility model, a first gear 17 is coaxially arranged on the outer wall of the rotating rod 8, and a second gear 18 is coaxially arranged on the outer wall of the rotating column 13.

[0065] The first gear 17 and the second gear 18 mesh with each other, and the thickness of the second gear 18 is greater than the thickness of the first gear 17.

[0066] In this embodiment, a first gear 17 is coaxially arranged on the outer wall of the rotating rod 8, and a second gear 18 is coaxially arranged on the outer wall of the rotating column 13. The first gear 17 and the second gear 18 mesh with each other, and the thickness of the second gear 18 is greater than the thickness of the first gear 17. Therefore, when the rotating column 13 slides along the central axis of the driving gear disk 5, although the second gear 18 slides along the rotating column 13, the first gear 17 and the second gear 18 can still maintain a meshed state. When the driven turntable 6 drives the rotating rod 8 to rotate, the first gear 17 will drive the rotating column 13 to rotate through the second gear 18, thereby causing the guide seat 3 to drive the blade of the blade 2 to rotate toward the inside of the mounting groove 101.

[0067] As a further embodiment of this utility model, the adjustment assembly also includes a guide plate 19 and a toothed plate 20. The guide plate 19 is disposed on the inner side wall of the cavity 102, and the toothed plate 20 meshes with the active toothed disc 5.

[0068] A T-shaped groove 1901 is provided on one side wall of the guide plate 19 along its length direction, and a T-shaped block 2001 is provided on one side wall of the toothed plate 20. The T-shaped block 2001 is located in the T-shaped groove 1901 and is slidably engaged.

[0069] A second spring 21 is provided in the T-shaped groove 1901. The two ends of the second spring 21 abut against the inner sidewall of the T-shaped block 2001 and the T-shaped groove 1901, respectively. The disassembly hole 103 corresponds to the position of the toothed plate 20.

[0070] In this embodiment, the toothed plate 20 is slidably mounted on the guide plate 19 by the cooperation of the T-shaped block 2001 and the T-shaped groove 1901. During disassembly, the toothed plate 20 is pushed to slide by a tool through the disassembly hole 103. Since the toothed plate 20 and the active toothed disc 5 mesh with each other, the active toothed disc 5 will rotate during the sliding of the toothed plate 20. Since a second spring 21 is provided in the T-shaped groove 1901, and the two ends of the second spring 21 abut against the inner sidewalls of the T-shaped block 2001 and the T-shaped groove 1901 respectively, the T-shaped block 2001 will squeeze the second spring 21 during the sliding of the toothed plate 20.

[0071] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
