Description

Technical Field

[0001] This utility model relates to the technical field of boring tools, and in particular to a boring tool for deep hole machining. Background Technology

[0002] A boring bar is a type of boring tool, generally with a round shank, although square shanks are sometimes used for larger workpieces. It is most commonly used for internal hole machining, reaming, and contouring. It has one or two cutting parts and is a tool specifically designed for roughing, semi-finishing, or finishing existing holes. A double-edged boring bar has two cutting teeth distributed on both sides of the center that cut simultaneously. Because the radial forces generated during cutting are balanced, the cutting parameters can be increased, resulting in high production efficiency.

[0003] Chinese utility model CN218612860U discloses a boring tool connecting device for a deep hole boring machine. It designs a boring tool mounting structure. The principle is that by rotating the ring body, the gear ring meshes with the gear, thereby causing the threaded rod to rotate and drive the threaded cylinder to move. The threaded cylinder drives the extrusion block, which can clamp one end of the boring tool to complete the installation.

[0004] However, the existing device uses a rotating installation method, which takes time and is inefficient. Therefore, a more convenient fixing structure was designed to address the above-mentioned problems. Utility Model Content

[0005] The purpose of this invention is to provide a boring tool for deep hole machining to solve the problems mentioned in the background art.

[0006] The technical solution adopted in this utility model is:

[0007] A boring tool for deep hole machining, comprising:

[0008] A mounting base has a housing on its outer side wall; a boring bar body has its top end inserted into the interior of the mounting base; a fixing assembly is provided inside the housing, the fixing assembly including: a slot formed on the top outer side wall of the boring bar body; a locking block disposed inside the housing and having one end penetrating through the outer side wall of the mounting base; a connecting rod rotatably disposed at one end of the locking block; a ring body fitted onto the outer side wall of the mounting base and having its bottom end rotatably connected to the top end of the connecting rod; a spring disposed inside the housing and having both ends connected to the ring body and the inner side wall of the housing; a through groove formed on the outer side wall of the housing; and a protruding rod having one end inserted into the through groove and connected to the ring body.

[0009] Optionally, one end of the card block is designed with a bevel.

[0010] Optionally, the fixing component further includes a connecting ring, which is sleeved on the outside of the housing and has its inner sidewall connected to one end of the protruding rod.

[0011] Optionally, the springs are evenly distributed on the top of the ring.

[0012] Optionally, the fixing component further includes: a groove formed at the bottom of the housing; and a slider whose top end is inserted into the interior of the groove and connected to the locking block.

[0013] Optionally, the mounting base is provided with a limiting component inside, the limiting component including: a positioning hole, which is opened at the top of the boring tool body; and a plug rod, which is disposed on the inner side wall of the top of the mounting base corresponding to the position of the positioning hole.

[0014] Optionally, the limiting component further includes a cone disposed at the bottom end of the insertion rod.

[0015] Optionally, the limiting component further includes a rubber block disposed on the inner sidewall of the top of the mounting base.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] The boring bar's fixing assembly uses the spring's rebound force to push the ring body downwards, and at the same time the spring moves downwards, it pushes the connecting rod to rotate, causing the bottom end of the connecting rod to drive the locking block to extend from inside the housing and insert into the slot to fix and install the boring bar.

[0026] In the description of this utility model, it should be understood that the terms "center," "longitudinal," "transverse," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," "counterclockwise," "axial," "radial," and "circumferential" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product of this utility model is in use, or the orientation or positional relationship commonly understood by those skilled in the art. They are only used to facilitate the description of this utility model and to simplify the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0027] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0028] The current technology works by rotating a ring to engage a gear ring, which in turn rotates a threaded rod, moving a threaded cylinder. This cylinder then moves a clamping block, which clamps one end of the boring bar to complete the installation. However, the current rotating installation method is time-consuming and inefficient.

[0029] like Figure 1-4 As shown, this embodiment of the invention provides a boring tool for deep hole machining.

[0030] The device includes: a mounting base 11 with a housing 12 on its outer side wall; a boring bar body 13 with its top end inserted into the mounting base 11; a fixing component 2 disposed inside the housing 12, the fixing component 2 including: a slot 21 formed on the outer side wall of the top end of the boring bar body 13; a locking block 22 disposed inside the housing 12 and with one end penetrating through the outer side wall of the mounting base 11; a connecting rod 23 rotatably disposed at one end of the locking block 22; a ring 24 sleeved on the outer side wall of the mounting base 11 and rotatably connected at its bottom end to the top end of the connecting rod 23; a spring 25 disposed inside the housing 12 and with both ends connected to the ring 24 and the inner side wall of the housing 12; a through groove 26 formed on the outer side wall of the housing 12; and a protruding rod 27 with one end inserted into the through groove 26 and connected to the ring 24.

[0031] In use, first install the mounting base 11 onto the output shaft of the boring machine. Then, simply move the protruding rod 27 upward inside the through slot 26, simultaneously causing the ring body 24 to move upward as well, and applying pressure to the spring 25. As the ring body 24 moves upward, it pulls the connecting rod 23 to rotate, causing one end of the connecting rod 23 to pull the locking block 22 back into the housing 12. At this point, insert the top of the boring tool into the mounting base 11 and rotate the adjustment slot 21 to align it with the locking block 22. Then, release the protruding rod 27, and the spring 25 will rebound, pushing the ring body 24 downward and causing the connecting rod 23 to rotate, pushing the locking block 22 into the mounting base 11 and into the slot 21 on the boring tool body 13, fixing it facing the boring tool body 13. Finally, the boring machine controls the position of the boring tool body 13 to drill holes in the workpiece.

[0032] Furthermore, one end of the card block 22 is designed with a bevel.

[0033] The beveled design allows the locking block 22 to retract into the housing as the boring bar body 13 is inserted. After the locking slot 21 and the locking block 22 are aligned, the spring 25 pushes the locking block 22 into the slot 21, making it easier to install the boring bar body 13.

[0034] Furthermore, the fixing component 2 also includes a connecting ring 28, which is sleeved on the outside of the housing 12 and whose inner sidewall is connected to one end of the protruding rod 27.

[0035] The design of the connecting ring 28 makes it easier to grip when the control rod 27 moves upward.

[0036] Furthermore, the springs 25 are evenly distributed on the top of the ring 24.

[0037] The uniform design of spring 25 ensures that the force is evenly distributed when pushing ring 24 downward.

[0038] Furthermore, the fixing component 2 also includes: a slide groove 29, which is formed at the bottom of the housing 12; and a slider 291, the top of which is inserted into the interior of the slide groove 29 and connected to the locking block 22.

[0039] The design of the groove 29 and the slider 291 can limit the movement trajectory of the block 22 when it moves, so that it can move stably.

[0040] Furthermore, the mounting base 11 is provided with a limiting component 3 inside. The limiting component 3 includes: a positioning hole 31, which is opened at the top of the boring bar body 13; and a plug rod 32, which is located on the inner side wall of the top of the mounting base 11, corresponding to the position of the positioning hole 31.

[0041] When the boring bar body 13 is inserted into the mounting base 11, the insertion rod 32 is inserted into the positioning hole 31 to restrict the rotation of the boring bar body 13, and at the same time, it can make the locking block 22 and the locking slot 21 aligned for easy installation.

[0042] Furthermore, the limiting component 3 also includes a cone 33 disposed at the bottom end of the insertion rod 32.

[0043] The pointed tip design at the bottom of the cone 33 makes it relatively easier to insert into the positioning hole 31.

[0044] Furthermore, the limiting component 3 also includes a rubber block 34, which is disposed on the inner sidewall of the top end of the mounting base 11.

[0045] The design of the rubber block 34 can reduce the impact of the top of the boring bar body 13 on the inside of the mounting base 11.

[0046] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
