Description

Technical Field

[0001] This utility model relates to the field of quick-release drill bit technology, specifically a quick-release deep hole drill bit. Background Technology

[0002] Deep hole drills are specifically designed for high-precision deep hole machining and are widely used in the machinery manufacturing, automotive, aerospace, oil and gas, and mold industries. Typical applications include the machining of precision components such as gun barrels, hydraulic cylinders, oil pump nozzles, and engine crankshaft oil holes. With their high rigidity structure, excellent chip removal capability, and high precision performance, deep hole drills can efficiently handle deep holes with a length-to-diameter ratio exceeding 50:1, making them a core technology and equipment for the manufacture of complex parts.

[0003] A search revealed a Chinese patent with publication number CN221096435U that discloses a quick-release drill bit connection mechanism for drilling, comprising a drill rig connector and a drill bit body. The drill rig connector is provided with a positioning seat, and a locking platform is movably engaged inside the positioning seat. A locking rod is fixedly connected to the locking platform, and a connecting joint is fixedly connected to the drill bit body.

[0004] While the above solution allows for quick disassembly of the connector and drill bit, its reliance on spring elasticity to lock the locking lever has significant drawbacks. Long-term exposure to strong vibrations can lead to metal fatigue due to reciprocating compression, causing the spring's elasticity to decrease. This reduces the stability of the locking lever and the locking hole, potentially resulting in accidental separation of the connector and drill bit. Therefore, we offer a quick-release deep hole drill bit to address these issues. Utility Model Content

[0005] The purpose of this invention is to provide a quick-release deep hole drill bit to solve the problems mentioned in the prior art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a quick-release deep hole drill bit, comprising a drill bit body, a quick-release mechanism disposed above the drill bit body, the quick-release mechanism comprising a drill rig connector, a drill bit connector slidably connected inside the drill rig connector, the bottom surface of the drill bit connector being fixedly connected to the drill bit body, a high-strength fixing post slidably connected to the inner wall of the drill rig connector, a connecting fixing groove adapted to the high-strength fixing post being formed on the outer surface of the drill bit connector, and a sealing limiting slide tube slidably connected to the outer surface of the drill rig connector.

[0007] Preferably, the inner wall of the drilling rig connector is slidably connected to an active slide, and the outer surface of the active slide is fixedly connected to a sealing and limiting slide tube. The drilling rig connector effectively limits the movement of the active slide.

[0008] Preferably, a hydraulic cylinder body is fixedly connected to the inner wall of the drilling rig connector. The telescopic end of the hydraulic cylinder body is fixedly connected to the active slide. By activating the hydraulic cylinder body to telescopically deform, the active slide can be driven to slide vertically within the inner wall of the drilling rig connector.

[0009] Preferably, a reinforcing column is fixedly connected to the inner wall of the drill bit connector, and the outer surface of the reinforcing column is slidably connected to the drill bit connector. The drill bit connector effectively fixes the reinforcing column.

[0010] Preferably, a reinforcing plate is fixedly connected to the inner wall of the drill bit connector, and the outer surface of the reinforcing plate is slidably connected to the reinforcing column. By sliding the drill bit connector into the drill rig connector, the reinforcing plate can be simultaneously embedded into the groove on the surface of the reinforcing column.

[0011] Preferably, a sealing mechanism is provided above the drill bit body. The sealing mechanism includes a connecting ring, the inner wall of which is fixedly connected to the drill rig connector. The drill rig connector effectively supports and fixes the connecting ring.

[0012] Preferably, the top surface of the connecting ring is provided with a sealing ring groove, and the bottom surface of the sealing limiting slide tube is fixedly connected with a sealing ring that matches the sealing ring groove. By embedding the sealing ring into the sealing ring groove, the connection between the drilling rig connector and the drill bit connector can be effectively sealed, effectively preventing debris generated during the operation of the drill bit body from entering the device cavity, avoiding the situation where the device cannot be used normally due to foreign object contamination, thereby significantly improving the overall service life of the device.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This application achieves linkage control of the ultra-strong fixed column by driving the sealing limit slide tube through the coordinated arrangement of the components in the quick-release mechanism. This not only enables the drill bit connector to be quickly separated from the drill rig connector, but also effectively prevents the drill bit connector from accidentally detaching from the drill rig connector while connected, significantly improving the operating efficiency and connection stability of the equipment.

[0015] 2. This application achieves a reliable sealing effect during the connection between the drill rig connector and the drill bit connector through the coordinated arrangement of the components in the sealing mechanism. This effectively prevents debris generated during the operation of the drill bit body from entering the device cavity, avoiding the situation where the device cannot be used normally due to foreign object contamination, thereby significantly improving the overall service life of the device.

[0021] 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.

[0022] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, this utility model provides a technical solution for a quick-release deep hole drill bit, including a drill bit body 1, a quick-release mechanism 2 on the top of the drill bit body 1, the quick-release mechanism 2 including a drill rig connector 201, a drill bit connector 202 slidably connected inside the drill rig connector 201, the bottom surface of the drill bit connector 202 being fixedly connected to the drill bit body 1, a super-strong fixing post 203 slidably connected to the inner wall of the drill rig connector 201, and a connection fixing groove 204 adapted to the super-strong fixing post 203 being opened on the outer surface of the drill bit connector 202. By embedding the super-strong fixing post 203 into the connection fixing groove 204, the drill bit connector 202 can be effectively limited and connected within the drill rig connector 201.

[0023] The high-strength fixing post 203 and the drill bit connector 202 are made of high-strength materials, which can effectively cope with the pressure during the rotation of the drill bit body 1.

[0024] A sealing and limiting slide tube 205 is slidably connected to the outer surface of the drilling rig connector 201, and an active slide 206 is slidably connected to the inner wall of the drilling rig connector 201. The outer surface of the active slide 206 and the sealing and limiting slide tube 205 are fixedly connected. Sealing rubber rings are fixedly installed at both ends of the sealing and limiting slide tube 205. The sealing rubber rings significantly improve the sealing performance between the sealing and limiting slide tube 205 and the drilling rig connector 201. The drilling rig connector 201 effectively limits the active slide tube 206, making the active slide tube 206 more stable as it slides the sealing and limiting slide tube 205 on the surface of the drilling rig connector 201.

[0025] A hydraulic cylinder body 207 is fixedly connected to the inner wall of the drilling rig connector 201. The telescopic end of the hydraulic cylinder body 207 is fixedly connected to the active slide 206. By starting the hydraulic cylinder body 207 to telescopically deform, the active slide 206 can be driven to slide vertically in the inner wall of the drilling rig connector 201. The upper surface of the drilling rig connector 201 is integrated with the control button of the hydraulic cylinder body 207. The hydraulic cylinder body 207 can be opened and closed effectively through the control button.

[0026] The hydraulic cylinder body 207 is a common electrical device in the prior art. This application will not elaborate on its model and internal structure. It can also be replaced by other power sources.

[0027] A reinforcing column 208 is fixedly connected to the inner wall of the drill rig connector 201. The outer surface of the reinforcing column 208 is slidably connected to the drill bit connector 202. The outer surface of the reinforcing column 208 has a groove that matches the reinforcing plate 209. The drill rig connector 201 effectively fixes the reinforcing column 208.

[0028] A reinforcing plate 209 is fixedly connected to the inner wall of the drill bit connector 202. The outer surface of the reinforcing plate 209 is slidably connected to the reinforcing column 208. By sliding the drill bit connector 202 into the drill rig connector 201, the reinforcing plate 209 can be simultaneously embedded into the groove on the surface of the reinforcing column 208. Through the synergistic effect of the reinforcing column 208 and the reinforcing plate 209, the drill bit body 1 can effectively distribute the pressure between the super-strong fixing column 203 and the connecting fixing groove 204 when rotating, thereby making the drill bit body 1 more stable during connection and use.

[0029] like Figure 3 and Figure 4 As shown, a sealing mechanism 3 is provided above the drill bit body 1. The sealing mechanism 3 includes a connecting ring 301. The inner wall of the connecting ring 301 is fixedly connected to the drill rig connector 201. The connecting ring 301 effectively supports and fixes the connecting ring 301.

[0030] A sealing ring groove 302 is provided on the top surface of the connecting ring 301, and a sealing ring 303 that matches the sealing ring groove 302 is fixedly connected to the bottom surface of the sealing limiting slide tube 205. By embedding the sealing ring 303 into the sealing ring groove 302, the connection between the drill rig connector 201 and the drill bit connector 202 can be effectively sealed, effectively preventing debris generated during the operation of the drill bit body 1 from entering the device cavity, avoiding the situation where the device cannot be used normally due to foreign object contamination, thereby significantly improving the overall service life of the device.

[0031] The structural diagrams of the components shown in the attached figures are exemplary. The specific implementation should be adapted and optimized by considering the functional requirements, assembly conditions and process limitations in the actual application scenario, and adjusting the structural parameters, size specifications and connection methods accordingly.

[0032] Working principle: First, the drill bit connector 202 is slid into the drill rig connector 201. At this time, the reinforcing plate 209 on the inner wall of the drill bit connector 202 will be simultaneously embedded into the groove of the reinforcing post 208. Second, the hydraulic cylinder body 207 is activated to contract and deform, pulling the active slide 206 down the inner wall of the drill rig connector 201. The movement of the active slide 206 simultaneously drives the sealing and limiting slide tube 205 down the outer surface of the drill rig connector 201. The downward movement of the sealing and limiting slide tube 205 will squeeze each super-strong fixing post 203 on the inner wall of the drill rig connector 201, so that one end of the super-strong fixing post 203 is embedded into the connecting fixing groove 204, thereby completing the connection of the drill bit body 1. The above process is reversed. This allows for quick disassembly of the drill bit body 1 from the drill rig connector 201. This optimization not only enables rapid separation of the drill bit connector 202 from the drill rig connector 201, but also effectively prevents the drill bit connector 202 from accidentally detaching from the drill rig connector 201 while connected, significantly improving operational efficiency and connection stability during equipment use. Secondly, during the process of the sealing limit slide tube 205 moving down to limit the ultra-strong fixing column 203, the sealing ring 303 can move down synchronously and embed into the sealing ring groove 302, ensuring a reliable sealing effect for the drill bit body 1 during connection. This effectively prevents debris generated during the operation of the drill bit body 1 from entering the device cavity, thereby significantly improving the overall service life of the device.

[0033] 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. No reference numerals in the claims should be construed as limiting the scope of the claims.
