[0001] This utility model relates to the field of metal cutting equipment technology, and in particular to a convenient modular pneumatic quick-change turning tool. Background Technology

[0002] Pneumatic quick-change turning tool is a turning tool assembly used in the field of metal cutting. It relies on compressed air as a power source to achieve rapid and precise connection and separation between the tool and the tool holder. This tool assembly can significantly shorten tool change time and reduce machining interruption time. At the same time, the standardized interface design ensures the positioning accuracy after tool change and avoids the impact of machining quality on the manual installation error. It is suitable for batch production and multi-process continuous machining scenarios.

[0003] When replacing existing lathe tools, it is mostly necessary to loosen the bolts and lock the tool holder. During the replacement process, the bolts need to be removed to take off the old tool. After installing the new tool, it is necessary to re-align and tighten the bolts one by one. The operation steps are cumbersome and time-consuming, which increases the interruption time of the machining process and affects the overall machining efficiency.

[0004] To address this, a convenient modular pneumatic quick-change cutting tool is proposed. Utility Model Content

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

[0014] This application utilizes a tool holder body, cylinder, steel ball holder, steel balls, and tool sleeve. In use, the cutting tool or drilling tool is first assembled into the tool sleeve, then the tool sleeve is inserted into the inner wall of the tool holder body. Subsequently, the cylinder at the top of the tool holder body is activated, driving the steel ball holder to engage with the steel balls on its inner wall, thus quickly locking the tool sleeve. This process eliminates the need for manual bolt removal, significantly reducing installation time and ensuring stable connection. When tool replacement is required, the cylinder is reversed to reset the steel ball holder, disengaging the steel balls from the tool sleeve. The old tool sleeve can then be directly removed and replaced with the new tool sleeve.

[0023] 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.

[0024] Please see Figure 1-7 The present invention provides the following technical solution:

[0025] A convenient modular pneumatic quick-change lathe tool includes a tool holder body 1, a cylinder 2 on the top of the tool holder body 1, a steel ball holder 3 on the inner wall of the tool holder body 1, steel balls 4 on the inner wall of the steel ball holder 3, and a tool sleeve 5 inserted into the inner wall of the tool holder body 1, with the surface of the steel balls 4 engaging with the inner wall of the tool sleeve 5.

[0026] In this embodiment, by setting up a tool holder body 1, a cylinder 2, a steel ball holder 3, steel balls 4, and a tool sleeve 5, in use, the lathe tool or drill bit is first assembled into the tool sleeve 5, and then the tool sleeve 5 is inserted into the inner wall of the tool holder body 1. Subsequently, the cylinder 2 at the top of the tool holder body 1 is activated, and the cylinder 2 drives the steel ball holder 3 to move, so that the steel balls 4 on the inner wall of the steel ball holder 3 engage with the inner wall of the tool sleeve 5, completing the quick locking of the tool sleeve 5. This process does not require manual disassembly and assembly of bolts, greatly shortening the installation time and ensuring stable connection. When it is necessary to replace the tool, the cylinder 2 is controlled to reverse the movement to drive the steel ball holder 3 to reset, so that the steel balls 4 disengage from the tool sleeve 5, and the old tool sleeve 5 can be directly pulled out and replaced with the tool sleeve 5 equipped with the new tool. Restarting the cylinder 2 completes the locking, simplifying the replacement steps and reducing the processing interruption time. At the same time, the tool sleeve 5 is compatible with different lathe tools and drill bits, and can meet diverse processing needs without adjusting the tool holder body 1.

[0027] Specifically, such as Figure 3 , Figure 4 As shown, the inner wall of the tool holder body 1 is provided with a bevel, and the outer wall of the tool sleeve 5 is provided with a positioning hole 6 for use with the steel ball 4.

[0028] Specifically, such as Figure 6 , Figure 7 As shown, the inner wall of the tool holder body 1 is movably connected to a telescopic structure 7, and the inner wall of the telescopic structure 7 is provided with a threaded shaft 8.

[0029] Specifically, such as Figure 6 As shown, a slider 9 is fixedly connected to the inner wall of the tool holder body 1, and the surface of the threaded shaft 8 is threadedly connected to the inner wall of the slider 9.

[0030] In this embodiment: the inclined surface of the inner wall of the tool holder body 1 cooperates with the steel ball 4. When the cylinder 2 drives the steel ball holder 3 to move, the inclined surface can guide and limit the steel ball 4, ensuring that the steel ball 4 is accurately inserted into the positioning hole 6 on the outer wall of the tool sleeve 5, improving the stability of the cooperation between the steel ball 4 and the positioning hole 6, and avoiding the steel ball 4 from shifting during processing, which would cause the tool sleeve 5 to loosen. The telescopic structure 7 and the threaded shaft 8 on the inner wall of the tool holder body 1 provide a structural basis for subsequent adjustment of the tool position. The telescopic structure 7 can be driven to move by the rotation of the threaded shaft 8, so as to realize the flexible adjustment of the position of the tool holder body 1 (facilitating the adjustment of the cutting position of the lathe tool center). The slider 9 fixed on the inner wall of the tool holder body 1 is threadedly connected to the surface of the threaded shaft 8. When the threaded shaft 8 rotates, it can drive the slider 9 to move in a specific direction through the threaded transmission, thereby driving the tool holder body 1 to move synchronously, ensuring the smoothness of the position adjustment process.

[0031] Specifically, such as Figure 7 As shown, a bearing 10 is fixedly connected to the surface of the threaded shaft 8, and the surface of the bearing 10 is fixedly connected to the inner wall of the telescopic structure 7.

[0032] Specifically, such as Figure 6 As shown, the inner wall of the tool holder body 1 is provided with an adjustment groove 11 that is used in conjunction with the telescopic structure 7, and the inner wall of the slider 9 is provided with a threaded hole 12 that is used in conjunction with the threaded shaft 8.

[0033] In this embodiment: By setting a bearing 10, the bearing 10 fixed on the surface of the threaded shaft 8 is fixedly connected to the inner wall of the telescopic structure 7. The bearing 10 can convert the rotational motion of the threaded shaft 8 into the linear motion of the telescopic structure 7, which facilitates the subsequent movement of the threaded shaft 8 and the slider 9 on the inner wall of the telescopic structure 7. The adjustment groove 11 opened on the inner wall of the tool holder body 1 prevents the tool holder body 1 from deviating during adjustment. The threaded hole 12 opened on the inner wall of the slider 9 ensures the accuracy of the threaded transmission between the threaded shaft 8 and the slider 9, and further improves the accuracy of tool position adjustment.

[0034] Specifically, such as Figure 5 , Figure 7 As shown, the top of the threaded shaft 8 is provided with an internal hexagonal groove 13, and the inner wall of the telescopic structure 7 is provided with a movable groove 14 that cooperates with the slider 9.

[0035] In this embodiment: the internal hexagonal groove 13 provided on the top of the threaded shaft 8 facilitates the adaptation of a hexagonal wrench, allowing the user to easily rotate the threaded shaft 8 with a hexagonal wrench, reducing the difficulty of operation and improving the convenience of position adjustment. The movable groove 14 opened on the inner wall of the telescopic structure 7 facilitates the movement of the slider 9 on the inner wall of the telescopic structure 7 through the movable groove 14.

[0036] Working principle: During the use of the tool holder body 1, first assemble the lathe tool or drill bit into the tool sleeve 5, then insert the tool sleeve 5 into the inner wall of the tool holder body 1. Start the top cylinder 2 of the tool holder body 1. The cylinder 2 drives the steel ball frame 3 to move along the inclined surface of the inner wall of the tool holder body 1, so that the steel balls 4 on the steel ball frame 3 are guided and squeezed into the positioning hole 6 on the outer wall of the tool sleeve 5 by the inclined surface, thereby locking the tool sleeve 5. When it is necessary to adjust the tool height, use a hex wrench to insert into the internal hexagonal groove 13 at the top of the threaded shaft 8 and rotate it, so that the threaded shaft 8 can drive the slider 9 to move along the inner wall of the tool holder body 1, thereby driving the tool holder body 1 to rise and fall to calibrate the tool center.

[0037] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
