Abstract
Description
Technical Field
[0001] This utility model relates to the field of turning tool technology, and in particular to the structure of a turning tool. Background Technology
[0002] The structure of a turning tool mainly consists of a cutting head (cutting part) and a tool body (clamping part). Different parts have different functions. The tool rotates at high speed to process the workpiece or cutting tool, and the cutting head of the tool contacts the workpiece to achieve cutting of the workpiece. There are many types of turning tools. When performing cutting work, the cutting head often needs to be changed multiple times, resulting in low cutting efficiency of the device.
[0003] However, existing technologies, such as Chinese Publication No. CN219581695U, "A Structure of a Turning Tool," which relates to the field of turning technology, disclose a structure for a turning tool, including a tool holder and two cutting heads. The two cutting heads are located on the left and right sides of the front end of the tool holder, respectively, for bidirectional cutting of the workpiece. Each of the two cutting heads has a limiting hole at its upper end, and a threaded hole is provided inside the lower inner wall of the limiting hole. A fixing arm is fixedly connected inside each of the two limiting holes, and limiting bolts pass through the upper and lower parts of each fixing arm. By setting cutting heads on the left and right sides of the front end of the tool holder, the product has cutting edges on both sides, enabling cutting of the workpiece in different directions. This increases the cutting structure and function of the product, avoids the need for frequent tool changes, reduces the number of tool changes, thereby improving turning efficiency. Simultaneously, reducing the number of tool changes effectively avoids positioning deviations caused by tool changes, resulting in higher and more stable workpiece machining accuracy and a lower product defect rate.
[0004] However, this device lacks an automatic rotating tool changing structure, making it unable to quickly and accurately switch the required tool to the working position. Manual tool changing is required, significantly increasing tool change time. Frequent tool changes reduce production efficiency. It cannot flexibly select and use appropriate tools according to different machining parts and process requirements, failing to meet diverse machining needs. Furthermore, the device lacks a structure to prevent tool vibration, preventing smooth cutting, increasing the generation of chatter marks, reducing the quality of machined surfaces, and hindering the improvement of wear resistance, corrosion resistance, and appearance quality of parts. It also increases abnormal tool wear, shortens tool life, and increases tool replacement frequency and costs. Utility Model Content
[0005] The purpose of this invention is to address the problems existing in the prior art, such as the inability to quickly and accurately switch the required tool to the working position, the need for manual tool replacement, which greatly increases tool change time, reduces production efficiency due to frequent tool changes, the inability to flexibly select and use appropriate tools according to different machining parts and process requirements, the inability to meet diverse machining needs, the inability to achieve smooth cutting, the increase in vibration marks, the reduction of machined surface quality, the disadvantage in improving the wear resistance, corrosion resistance and appearance quality of parts, the increase in abnormal tool wear, the shortening of tool life, and the increase in tool replacement frequency and cost.

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.
[0025] Please see Figures 1 to 5 This utility model provides a technical solution: a turning tool structure, including a main housing 1, a rotating rod 2 rotatably connected to one side of the main housing 1, a rotating plate 3 fixedly connected to one end of the rotating rod 2, a plurality of connecting rods 4 fixedly connected to the outer surface of the rotating plate 3, a rotating ring 5 fixedly connected to the end of the plurality of connecting rods 4 away from the rotating plate 3, a force-receiving groove 6 is opened on one side driven by the connecting rods 4 and the rotating ring 5, a force-applying rod 7 is movably embedded inside the force-receiving groove 6, a crank 8 fixedly connected to one end of the force-applying rod 7, a power rod 9 fixedly connected to the side of the crank 8 away from the force-applying rod 7, the outer surface of the power rod 9 rotatably connected to one side of the main housing 1, for every one rotation of the power rod 9, the rotating rod 2 rotates a quarter rotation, when the power rod 9 rotates two rotations, the rotating rod 2 and the main rod 12 will rotate half a rotation, causing the main rod 12 to turn the tool head 23.
[0026] like Figures 1 to 5 As shown, a first mounting sleeve 10 is fixedly connected to one side of the main housing 1. A first motor 11 is fixedly embedded on the inner surface of the first mounting sleeve 10. The output end of the first motor 11 is fixedly connected to one end of the power rod 9. When the first motor 11 is powered on, it will drive the power rod 9, the crank 8 and the force rod 7 to rotate around the power rod 9 as the axis.
[0027] like Figures 1 to 5As shown, the end of the rotating rod 2 away from the rotating plate 3 is fixedly connected to the main rod 12. The main rod 12 has two stabilizing holes 13 on the side near the main housing 1. The stabilizing rod 17 is embedded in the stabilizing hole 13 to prevent the cutter head 23 from vibrating during operation.
[0028] like Figures 1 to 5 As shown, a threaded rod 14 is rotatably connected inside the main housing 1, and an inner threaded sleeve 15 is threadedly connected to the outer surface of the threaded rod 14. A fixing plate 16 is fixedly sleeved on the outer surface of the inner threaded sleeve 15. Rotating the thread will drive the inner threaded sleeve 15.
[0029] like Figures 1 to 5 As shown, a stabilizing rod 17 is fixedly connected to one side of the fixing plate 16. The outer surface of the stabilizing rod 17 is movably embedded in one side of the main housing 1, and the outer surface of the stabilizing rod 17 is movably embedded in the inside of the stabilizing hole 13.
[0030] like Figures 1 to 5 As shown, the outer surface of the stabilizer bar 17 is movably fitted with a limiting sleeve 18. One side of the limiting sleeve 18 is fixedly connected to the inner surface of the main housing 1. Rotating the thread will drive the internal thread sleeve 15, causing the fixing plate 16 and the stabilizer bar 17 to retract around the limiting sleeve 18 as the axis, and preventing the stabilizer bar 17 from being embedded in the stabilizer hole 13.
[0031] like Figures 1 to 5 As shown, a second mounting sleeve 19 is fixedly connected to the side of the main housing 1 near the first mounting sleeve 10. A second motor 20 is fixedly embedded on the inner surface of the second mounting sleeve 19. The output end of the second motor 20 is fixedly connected to one end of the threaded rod 14. The second motor 20 is fixed to one side of the main housing 1 through the second mounting sleeve 19.
[0032] like Figures 1 to 5 As shown, both ends of the main rod 12 are fixedly connected to connecting blocks 21. An insert 22 is movably embedded inside the connecting block 21. A cutter head 23 is fixedly connected to one end of the insert 22. An internal hexagon block 24 is provided on one side of the connecting block 21. A screw 25 is fixedly connected to one side of the internal hexagon block 24. The outer surface of the screw 25 is threaded to one side of the insert 22. Rotating the screw 25 will embed into one side of the insert 22, further fixing the cutter head 23.
[0033] Working principle: First, different cutting heads 23 are embedded into the connecting block 21 through the insert 22. Then, the screw 25 is rotated by rotating the internal hexagon block 24. The rotating screw 25 will be embedded into one side of the insert 22, further fixing the cutting head 23. When the cutting head 23 needs to be changed during operation, the external power supply of the second motor 20 is first turned on. The second motor 20 is fixed to one side of the main housing 1 through the second mounting sleeve 19. After the second motor 20 is powered on, it will drive the threaded rod 14 to rotate. The rotation of the thread will drive the internal threaded sleeve 15, causing the fixing plate 16 and the stabilizing rod 17 to retract around the limiting sleeve 18 as the axis, and the stabilizing rod 17 will no longer be embedded in the stabilizing hole 13. Then, the external power supply of the first motor 11 is turned on. The first motor 11 is driven by the external power supply of the first motor 11. The first mounting sleeve 10 is fixed to one side of the main housing 1. After the first motor 11 is powered on, it will drive the power rod 9, crank 8 and force rod 7 to rotate around the power rod 9 as the axis. When the force rod 7, which is making circular motion, moves inside the force groove 6, it will drive the rotating rod 2, rotating plate 3, connecting rod 4 and rotating ring 5 to rotate around the rotating rod 2 as the axis. For every one rotation of the power rod 9, the rotating rod 2 rotates a quarter rotation. When the power rod 9 rotates twice, the rotating rod 2 and the main rod 12 will rotate half a rotation, causing the main rod 12 to turn the cutter head 23. Then, the external power supply of the second motor 20 is started again, which drives the threaded rod 14 to rotate in the opposite direction, so that the stabilizing rod 17 is embedded in the stabilizing hole 13 again, which can prevent the cutter head 23 from vibrating during operation.

Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
