Description

Technical Field

[0001] This utility model relates to the field of deep hole machining tool technology, specifically a deep hole machining tool mounting structure. Background Technology

[0002] Deep hole machining technology is widely used in aerospace, mold manufacturing and other fields to process precision holes with a large diameter-to-depth ratio (L / D). This type of machining usually employs processes such as deep hole drilling, deep hole boring, and deep hole honing, and has extremely high requirements for machining accuracy, surface quality and efficiency.

[0003] In deep hole machining, the stability, precision, and ease of use of the cutting tool and its mounting structure are key factors in ensuring machining quality and improving production efficiency. Most existing deep hole tool mounting structures employ multi-stage threaded connections, numerous fastening bolts (screws), or complex clamping sleeve structures to ensure stability in the axial, radial, and circumferential directions.

[0004] However, in the existing technology, during installation, disassembly and debugging, personnel need to loosen or tighten bolts multiple times, which results in a cumbersome disassembly and installation process, long time consumption and high labor intensity for personnel. Utility Model Content

[0005] To address the aforementioned shortcomings of existing technologies, this utility model provides a deep hole machining tool mounting structure. By rotating the push ring, the limiting plate, the moving plate, and the moving rod move and press towards the wedge block, causing the wedge block to be squeezed tightly into the slot, thereby achieving axial and radial fixation. The cooperation between the limiting rod and the limiting hole achieves circumferential and radial fixation. Disassembly can be performed by rotating the push ring in the opposite direction. The structure is simple, disassembly and installation are convenient, and disassembly and assembly efficiency is improved.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a deep hole machining tool mounting structure, comprising a rotating shaft for driving the tool to rotate, a tool holder, a fixed sleeve, a disc, a push ring, and a sliding assembly. The connecting end of the rotating shaft is fixedly connected to one end of the fixed sleeve, and the other end of the fixed sleeve is fixedly connected to the bottom surface of the disc. The fixed sleeve, the disc, and the rotating shaft are coaxial. An external thread is formed on the side surface of the fixed sleeve, and an internal thread is formed on the inner ring of the push ring. The push ring is mounted on the fixed sleeve through a screw-fitting engagement of the internal and external threads. Multiple sliding openings are evenly formed axially on the fixed sleeve. Multiple limiting plates are radially inserted into the sliding openings, and the limiting plates can slide axially within the sliding openings. One outer end of the limiting plate is circumferentially connected to the side wall of the push ring via the sliding assembly. Next, a movable plate is fixedly connected to one end of the inner side of multiple limiting plates. A movable rod is fixedly installed at the center position of one side of the movable plate corresponding to the disk. A through hole is opened at the center position of the disk. The movable rod is axially inserted into the through hole. A fixed ring is provided on the side of the disk away from the fixed sleeve and the fixed ring is coaxial with the disk. Multiple wedge blocks are evenly arranged on the fixed ring. The wedge blocks are rotatably connected to the fixed ring in the radial direction. Multiple limiting rods are evenly arranged on the side of the disk away from the fixed sleeve. A dovetail-shaped groove is opened at the center position of the end face of the tool bar. A limiting hole is opened on the end face of the tool bar corresponding to the position of the limiting rod. Multiple wedge blocks can be inserted into the groove and the limiting rods are inserted into the limiting holes at the same time. The movable rod moves into the groove and can push the wedge blocks to squeeze against the inner wall of the groove.

[0007] Preferably, the sliding assembly includes multiple sliders, which are fixedly disposed at one end of the outer side of the limiting plate. The push ring has a groove corresponding to the position of the slider, and the slider is slidably connected to the groove.

[0008] Preferably, the side surface of the push ring is provided with a plurality of insertion holes in the radial direction.

[0009] Preferably, an anti-loosening nut is screwed onto one side of the fixed sleeve corresponding to the rotating shaft.

[0010] Preferably, a ball is fixedly provided on one side of the movable rod corresponding to the slot.

[0011] Preferably, the end of the limiting rod corresponding to the limiting hole is chamfered.

[0012] This utility model provides a tool mounting structure for deep hole machining, which has the following advantages: 1. This utility model uses a rotating push ring to drive the limiting plate, moving plate, and moving rod to move and press the wedge block, so that the wedge block is squeezed into the slot, thereby achieving the purpose of axial and radial fixation. The cooperation between the limiting rod and the limiting hole achieves the purpose of circumferential and radial fixation. The push ring can be rotated in the opposite direction to disassemble. The structure is simple, disassembly and installation are convenient, and disassembly and assembly efficiency is improved. 2. In this utility model, a sliding component is provided between the limiting plate and the push ring, which adopts the method of sliding block and sliding groove cooperation. When the two rotate relative to each other, the friction is reduced, making the operation smoother and less labor-intensive. The anti-loosening nut is set to prevent the push ring from loosening after connection, which would affect the stability of the connection. Multiple insertion holes are evenly opened on the side surface of the push ring, which makes it convenient for personnel to use insertion rod tools to insert into the insertion holes to rotate the push ring.

[0016] like Figure 1-3As shown, a deep hole machining tool mounting structure includes a rotating shaft 1 for driving the tool to rotate, a tool holder 10, a fixed sleeve 20, a disc 7, a push ring 18, and a sliding assembly. The connecting end of the rotating shaft 1 is fixedly connected to one end of the fixed sleeve 20, and the other end of the fixed sleeve 20 is fixedly connected to the bottom surface of the disc 7. The fixed sleeve 20, the disc 7, and the rotating shaft 1 are coaxial. The side surface of the fixed sleeve 20 is provided with external threads, and the inner ring of the push ring 18 is provided with internal threads. The push ring 18 is mounted on the fixed sleeve 20 through a screw-fitting engagement of the internal and external threads. The fixed sleeve 20 has multiple axially evenly spaced sliding openings 2. Multiple limiting plates 16 are radially inserted into each sliding opening 2, and the limiting plates 16 can slide axially within the sliding opening 2. One outer end of each limiting plate 16 is slidably connected to the circumferential side wall of the push ring 18 via a sliding assembly. One inner end of each limiting plate 16 is fixedly connected to a moving plate 3. A moving rod 6 is fixedly positioned at the center of one side of the moving plate 3 corresponding to the disk 7. A through hole 15 is opened at the center of the disk 7, and the moving rod 6 is axially inserted into the through hole 15. A [missing information - likely a typo, should be "on the side of the disk 7 away from the fixed sleeve 20"]. A fixed ring 14 is coaxial with the disk 7. Multiple wedge-shaped blocks 9 are evenly distributed on the fixed ring 14, and the wedge-shaped blocks 9 are rotatably connected to the fixed ring 14 in the radial direction. Multiple limiting rods 8 are evenly distributed on the side of the disk 7 away from the fixed sleeve 20. A dovetail-shaped groove 11 is formed at the center of the end face of the tool bar 10. Limiting holes 13 are formed on the end face of the tool bar 10 corresponding to the positions of the limiting rods 8. Multiple wedge-shaped blocks 9 can be inserted into the groove 11, and simultaneously, the limiting rods 8 are inserted into the limiting holes 13. The moving rod 6 can move into the groove 11. The wedge block 9 is pushed to press against the inner wall of the slot 11; the sliding assembly includes multiple sliders 5, which are fixedly disposed at one end of the outer side of the limiting plate 16; the push ring 18 has a groove 17 corresponding to the position of the slider 5, and the slider 5 is slidably connected to the groove 17; multiple insertion holes 4 are radially provided on the side surface of the push ring 18; an anti-loosening nut 19 is screwed onto the side of the fixed sleeve 20 corresponding to the rotating shaft 1; a ball 12 is fixedly disposed on the side of the moving rod 6 corresponding to the slot 11; the end of the limiting rod 8 corresponding to the limiting hole 13 is chamfered.

[0017] Its detailed connection methods are well-known technologies in this field. The following mainly introduces the working principle and process, as follows: According to the instruction manual Figure 1-3It is understood that the fixed sleeve 20 and the disc 7 on the connecting end of the rotating shaft 1 in this utility model can be connected by welding. The push ring 18 is screwed to the fixed sleeve 20 by thread connection. The limiting plate 16, the moving plate 3, and the moving rod 6 can move axially by rotating the push ring 18. The sliding connection between the limiting plate 16 and the sliding port 2, as well as the relative rotation between the limiting plate 16 and the push ring 18 through the sliding component, ensure the stability of the movement of the limiting plate 16, the moving plate 3, and the moving rod 6. Here, the limiting plate 16, the moving plate 3, the moving rod 6, the disc 7, and the fixed sleeve 20 are all made of alloy materials with sufficient strength, which can be conceived by those skilled in the art. During connection and installation, the end face of the tool holder 10 is inserted into the disc 7, causing multiple wedge blocks 9 to be inserted into the dovetail-shaped slot 11. Here, the dovetail-shaped slot 11 refers to a slot with a bottom larger than the opening and its sidewalls inclined. At the same time as the multiple wedge blocks 9 are inserted into the dovetail-shaped slot 11, the limiting rod 8 is also inserted into the limiting hole 13. The cooperation between the limiting rod 8 and the limiting hole 13 can limit and fix the tool holder 10 and the rotating shaft 1 in the radial and circumferential directions. The operator rotates the push ring 18 to move it axially, thereby driving the limiting plate 16, the moving plate 3, and the moving rod 6. Axial movement causes the moving rod 6 to press against the radially rotating wedge block 9, thus tightly pressing the wedge block 9 against the side wall of the slot 11. This radial and axial positioning and fixation of the tool holder 10 and the rotating shaft 1 ensures the stability of the connection between the tool holder 10 and the rotating shaft 1. The limiting rod 8, wedge block 9, fixing ring 14, and the connection between the wedge block 9 and the fixing ring 14 all require sufficient strength. Since the tool rotates at high speed during operation, those skilled in the art can understand the strength of the materials used for the components and the strength of the connection points; these details will not be elaborated here. This invention uses a rotating push ring 18 to move and press the limiting plate 16, the moving plate 3, and the moving rod 6 towards the wedge block 9, causing the wedge block 9 to be tightly pressed into the slot 11, thereby achieving axial and radial fixation. The cooperation between the limiting rod 8 and the limiting hole 13 achieves circumferential and radial fixation. Disassembly is achieved by rotating the push ring 18 in the opposite direction. Compared to the numerous bolts or screws used in existing technologies, this design is simpler, easier to disassemble and install, and improves assembly and disassembly efficiency.

[0018] The sliding component includes multiple sliders 5, which are fixedly installed on one side of the limiting plate 16. A groove 17 is formed on the push ring 18 corresponding to the position of the slider 5. The slider 5 is slidably connected to the groove 17. By using the cooperation between the slider 5 and the groove 17, friction is reduced when the two rotate relative to each other, making the operation smoother and less labor-intensive.

[0019] The push ring 18 has multiple insertion holes 4 radially opened on its side surface, which makes it convenient for personnel to use insertion tools to insert into the insertion holes 4 and rotate the push ring 18 by force.

[0020] Among them, the fixed sleeve 20 is screwed with an anti-loosening nut 19 on the side corresponding to the rotating shaft 1 to prevent the push ring 18 from loosening after connection and affecting the stability of the connection.

[0021] Among them, a ball 12 is fixedly installed on one side of the moving rod 6 corresponding to the slot 11. The ball 12 pushes against the wedge block 9, resulting in less friction and smoother operation. Similarly, the end of the limiting rod 8 corresponding to the limiting hole 13 is chamfered to facilitate insertion into the limiting hole 13.

[0022] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
