Description

Technical Field

[0001] This utility model relates to the field of turning tool fixture technology, and in particular to a multi-angle adjustable turning tool fixture. Background Technology

[0002] Turning tool holders, commonly known as "tool holders" or "tool pedestals," are one of the core components of CNC lathes and conventional lathes. Their main function is to accurately and reliably hold turning tools (such as turning tools, boring tools, drills, etc.) and fix them in a specific position on the machine tool.

[0003] Traditional tool holders (such as ordinary tool posts) typically use pressure plates and multiple bolts for fixing. Each time the main cutting edge angle, secondary cutting edge angle, or inclination angle of the tool needs to be adjusted, the operator must loosen multiple bolts, roughly locate the required angle manually or with the help of other tools (such as an angle gauge), and then retighten them. This process is not only slow, but also heavily relies on the operator's experience and eyesight, resulting in poor repeatability. Therefore, to solve the above problems, a multi-angle adjustable turning tool holder is proposed. Utility Model Content

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.

[0018] Example 1 like Figures 1-4 As shown, the present invention proposes a multi-angle adjustable turning tool fixture, including an adjusting slide rail 10 and a base box 2 slidably disposed on its inner side. The bottom of the adjusting slide rail 10 is hollowed out. A base plate 27 is rotatably disposed on the top of the base box 2. An angle adjusting assembly is disposed on the base plate 27. The angle adjusting assembly includes multiple tool mounting cylinders 23. The tool mounting cylinders 23 are rotatably disposed on the top of the base plate 27. A tool body 22 is mounted on the inner side of the tool mounting cylinder 23. An adjusting worm wheel 213 is fixedly mounted on the bottom of the tool mounting cylinder 23. An adjusting worm 215 is engaged on the outer side of the adjusting worm wheel 213. The adjusting worm 215 and the adjusting worm wheel 213 are mutually engaged and have self-locking properties.

[0019] Example 2 like Figures 1-4 As shown, based on Embodiment 1, in this embodiment, an adjusting motor 1 is fixedly installed at one end of the adjusting slide rail 10, an adjusting screw 11 is fixedly installed at the output end of the adjusting motor 1, and a threaded block 20 that slides relative to the adjusting slide rail 10 is threadedly connected to the outer side of the adjusting screw 11. The threaded block 20 is fixedly connected to the base box 2.

[0020] The angle adjustment assembly also includes a blade adjusting motor 21 fixedly installed inside the base box 2, a base plate 27 rotatably connected to the top of the base box 2, an outer wall cylinder 28 fixedly connected to the top of the base plate 27, and a top plate 26 fixedly connected to the top of the outer wall cylinder 28.

[0021] The output end of the adjusting motor 21 is fixedly connected to a drive shaft 25. The drive shaft 25 is rotatably connected to the top plate 26 and the bottom plate 27. A fixing ring 29 is fixedly connected to the outside of the drive shaft 25. The top and bottom of the fixing ring 29 are fixedly connected to the top plate 26 and the bottom plate 27, respectively.

[0022] The top of the base plate 27 is rotatably connected to a plurality of second rotating rods 211, which are fixedly connected to the adjusting worm gear 213. The top of the tool mounting cylinder 23 is fixedly connected to a first rotating rod 24, which is rotatably connected to the top plate 26.

[0023] The top of the base plate 27 is fixedly connected to multiple pairs of bearing seats 214. Two bearing seats 214 are rotatably connected to the adjusting worm 215. One end of the adjusting worm 215 is fixedly connected to an internal hexagonal adjusting head 210.

[0024] The tool body 22 is slidably disposed inside the tool mounting cylinder 23. Both the tool body 22 and the tool mounting cylinder 23 are provided with threaded fixing holes 220. The inner side of the threaded fixing holes 220 is threaded with an internal hexagonal fixing bolt 212.

[0025] An adjustment port 280 and a deflection groove 281 are equidistantly provided on the outer circumference of the outer wall cylinder 28. The deflection groove 281 is aligned with the position of the internal hexagon adjustment head 210. The tool mounting cylinder 23 swings inside the adjustment port 280.

[0026] In actual production, producing a qualified product often requires the cooperation of multiple cutting tools. During the cutting process, it is necessary to measure the dimensions of the workpiece and the angles at various points at all times. This requires adjusting the angle of the cutting tools. During the tool setting and retraction process, it is necessary to adjust the lateral position of the base box 2. The pitch motor 1 is started, and the pitch motor 1 drives the adjusting screw 11 at its output end to rotate. Since the adjusting screw 11 is threadedly connected to the threaded block 20, and the threaded block 20 is fixedly connected to the base box 2, and the threaded block 20 is slidably set on the inner side of the adjusting slide rail 10, the rotational motion of the adjusting screw 11 will be converted into the linear motion of the threaded block 20 together with the base box 2 along the adjusting slide rail 10, thereby realizing the position adjustment of the base box 2 relative to the machine tool spindle. Furthermore, regarding the angle adjustment of the tool body 22, the tool mounting cylinder 23 deflects on the base plate 27. To achieve this, the operator can operate the hexagonal head 210 through the adjustment port 280. The hexagonal head 210 drives the adjusting worm 215, which is fixedly connected to it, to rotate. Since the adjusting worm 215 meshes with the adjusting worm wheel 213 and the worm wheel and worm pair have self-locking properties, the rotation of the adjusting worm 215 will drive the adjusting worm wheel 213 and the tool mounting cylinder 23 on it to rotate around the axis of the second rotating rod 211 within a certain angle range. The deflection groove 281 is provided with a scale, and the tool mounting cylinder 23 is provided with a pointer. By observing the pointer corresponding to the scale, the angle adjustment of the tool body 22 is completed. And due to the self-locking property, the angle adjustment can be stably maintained. Furthermore, when it is necessary to change the radial distribution of all tools, that is, when it is necessary to switch different tools, the tool adjusting motor 21 is started. The tool adjusting motor 21 drives the transmission shaft 25 at its output end to rotate. Since the transmission shaft 25 is fixedly connected to the top plate 26 and the bottom plate 27 through the fixing ring 29, the rotation of the transmission shaft 25 will drive the entire structure consisting of the top plate 26, the outer wall cylinder 28 and the bottom plate 27 to rotate together on the top of the base box 2. This allows all the tool mounting cylinders 23 and the internal tool bodies 22 that are mounted on this structure through the first rotating rod 24 and the adjusting worm gear 213 to revolve synchronously, thereby adjusting the position of the tool in the circumferential direction. Furthermore, the tool body 22 is slidably mounted on the inner side of the tool mounting cylinder 23 and locked in place by an internal hexagonal bolt 212 through the threaded fixing hole 220 on the tool body 22 and the tool mounting cylinder 23. During operation, the tool mounting cylinder 23 is deflected to its maximum angle, and then the tool is installed by inserting it into the outer wall cylinder 28 from the deflection groove 281. This design provides a turning tool fixture that can achieve precise adjustment at multiple angles and positions and has good stability.

[0027] 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.
