Description

Technical Field

[0001] This utility model relates to the field of lathe tool technology, and in particular to an adjustable lathe tool that can adapt to different cutting angles. Background Technology

[0002] In the field of machining, the lathe tool is the core component of lathe machining, and the accuracy of its cutting angle directly affects the machining quality, surface finish, and cutting efficiency of the workpiece. Currently, most lathe tools used are of fixed angle structure. Once the machining requirements change, it is often necessary to replace the entire tool with one of the corresponding angles. This not only increases tool inventory and management costs, but also reduces production efficiency due to frequent replacements, making it difficult to meet the high-efficiency machining requirements of multi-variety, small-batch, and complex contour parts.

[0003] Therefore, there is an urgent need for a cutting tool structure that can flexibly and precisely adjust the cutting angle without changing the tool, and has reliable locking capability, in order to improve machining flexibility, reduce tool change time, and ensure the stability and accuracy of the cutting process. Utility Model Content

[0004] In order to overcome the shortcomings mentioned in the background art, this utility model provides an adjustable turning tool that can adapt to different cutting angles.

[0005] The technical solution is as follows: An adjustable turning tool that can adapt to different cutting angles includes a tool holder, an adjusting shank, a positioning shaft, an adjusting tool disc, a positioning bolt, a turning tool, and graduation lines. The adjusting shank is axially slidably connected inside the tool holder. The left end of the adjusting shank is rotatably connected to the positioning shaft via a bearing. The adjusting tool disc is fixedly connected to the outside of the positioning shaft. The turning tool is mounted on the left end face of the adjusting tool disc. A mounting hole is opened in the middle of the top of the positioning shaft. The positioning bolt is screwed into the mounting hole, and its bottom end face is embedded inside the adjusting shank. Graduation lines are engraved circumferentially on the top surface of the adjusting tool disc.

[0006] Furthermore, the tool holder and adjusting handle are integrally forged from alloy steel.

[0007] Furthermore, the surface of the scale lines on the adjusting blade is filled with luminescent material.

[0008] Furthermore, it also includes positioning strips, a pre-positioned block, a compression spring, and a locking bolt. The outer surface of the right part of the adjusting cutter head is provided with several positioning strips at intervals. A sliding groove is opened on the left side of the inside of the adjusting handle. The pre-positioned block is slidably connected in the sliding groove. A notch is opened at the left end of the pre-positioned block. The pre-positioned block is engaged with the positioning strip at the corresponding position through the notch. A compression spring is connected between the right end face of the pre-positioned block and the inside of the sliding groove. An elongated hole is opened in the pre-positioned block. A mating hole is opened at the corresponding position on the top of the adjusting handle. The locking bolt is installed in the mating hole and extends into the elongated hole.

[0009] Furthermore, it also includes screws and a return spring. The section inside the adjusting handle located inside the tool holder has multiple through holes spaced apart along the axial direction. The top left side of the tool holder has a positioning hole that mates with the screw. The screw is screwed into the positioning hole and can be inserted into the corresponding through hole. A return spring is connected between the right side of the adjusting handle and the right side of the tool holder.

[0010] Furthermore, the positioning bolts feature a fine-pitch thread design.

[0011] The beneficial effects of this utility model are as follows: 1. By rotating the adjustable tool disc with scale lines, the tool angle can be infinitely adjusted, and the adjustment accuracy can be improved according to the scale markings. The positioning bolt can directly press the positioning shaft to ensure reliable locking after angle adjustment, effectively guaranteeing the accuracy and repeatability of cutting.

[0012] 2. The pre-positioned block engages with the positioning strip under the action of the compression spring, which can provide preliminary positioning before formal locking and prevent the adjusting cutter head from rotating on its own during the adjustment process. This structure plays a buffering and anti-slip role when the positioning bolts are loosened, improving the controllability and safety of operation. After installation, it can further fix the angle of the adjusting cutter head.

[0013] 3. The position of the adjusting handle is fixed by screws and through holes, and the extension and retraction power is provided by the return spring, which can realize flexible adjustment of the overall length of the device. This function expands the installation range of the cutting tool and is suitable for the machining needs of lathes of different specifications and deep cavity parts. Attached Figure Description

Detailed Implementation

[0019] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0020] Example: An adjustable turning tool that can adapt to different cutting angles, such as... Figures 1-2 As shown, the device includes a tool holder 1, an adjusting handle 2, a positioning shaft 3, an adjusting tool disc 4, a positioning bolt 5, a lathe tool 6, and graduation lines 12. The tool holder 1 serves as the main support structure and is used to mount the lathe tool post. The adjusting handle 2 is axially slidably connected inside the tool holder 1. The tool holder 1 and the adjusting handle 2 are integrally forged from alloy steel, possessing high rigidity and wear resistance, effectively extending the overall service life. The left end of the adjusting handle 2 is rotatably connected to the positioning shaft 3 via a bearing. The adjusting tool disc 4 is fixedly connected to the outside of the positioning shaft 3. The lathe tool 6 is mounted on the left end face of the adjusting tool disc 4. A mounting hole is opened in the middle of the top of the positioning shaft 3, into which the positioning bolt 5 is screwed, and its bottom end face is embedded inside the adjusting handle 2, thereby locking the horizontal rotation of the positioning shaft 3. Bolt 5 features a fine-thread design, improving the precision of preload control during locking, making the clamping process smoother and the angle fixation more reliable. When adjusting the angle of the cutting tool 6, use a tool to loosen the positioning bolt 5 to release the clamping effect on the positioning shaft 3. Then, rotate the adjusting tool disc 4 to rotate the positioning shaft 3 and the cutting tool 6 together, thereby adjusting the angle of the cutting tool 6. After adjustment, tighten the positioning bolt 5 again to fix the position of the positioning shaft 3. The top surface of the adjusting tool disc 4 is engraved with scale lines 12 along the circumference. During the adjustment process, the scale markings can be used as a reference to achieve precise control of the angle of the cutting tool 6. The surface of the scale lines 12 is filled with luminescent material, which can still be clearly identified in low-light environments, making it convenient for operators to adjust the angle under different lighting conditions.

[0021] like Figures 3-4 As shown, it also includes positioning strips 7, a pre-positioned block 8, a compression spring 9, and a locking bolt 11. Several positioning strips 7 are spaced apart on the outer surface of the right part of the adjusting cutter disc 4. A sliding groove is provided inside the left side of the adjusting handle 2, and the pre-positioned block 8 is slidably connected within this groove. A notch is provided at the left end of the pre-positioned block 8, which engages with the corresponding positioning strip 7. A compression spring 9 connects the right end face of the pre-positioned block 8 to the inside of the sliding groove. An elongated hole 10 is provided inside the pre-positioned block 8, and a corresponding mating hole is provided at the top of the adjusting handle 2. The locking bolt 11 is installed in the mating hole and extends into the elongated hole 10 to restrict the sliding of the pre-positioned block 8. The stroke is adjusted to improve the positional stability of the adjusting cutter head 4 after angle adjustment. During the adjustment process, when the positioning bolt 5 is loosened first, the pre-positioned block 8 and the positioning strip 7 are engaged, which can prevent the adjusting cutter head 4 from moving due to friction. After the positioning bolt 5 is loosened, the locking bolt 11 is removed, so that the pre-positioned block 8 is in a sliding state. At this time, the adjusting cutter head 4 is rotated, and the positioning strip 7 pushes the pre-positioned block 8 to move back and forth. The compression spring 9 provides elastic restoring force. When the angle of the cutting tool 6 is adjusted to the position, the pre-positioned block 8 is reset under the action of the spring, and the notch is re-engaged into the corresponding positioning strip 7. Then the positioning bolt 5 is tightened again and the locking bolt 11 is installed to stabilize the overall structure.

[0022] like Figures 1-2As shown, it also includes a screw 13 and a return spring 15. The section inside the adjusting handle 2 located inside the tool holder 1 is provided with multiple through holes 14 spaced apart along the axial direction. The top left side of the tool holder 1 is provided with a positioning hole that cooperates with the screw 13. The screw 13 is screwed into the positioning hole and can be inserted into the corresponding through hole 14 to limit the axial position of the adjusting handle 2. A return spring 15 is connected between the right side of the adjusting handle 2 and the right side of the tool holder 1. In the initial state, the return spring 15 is in a compressed state. When the screw 13 is removed, the return spring 15 releases its elastic potential energy and pushes the adjusting handle 2 to extend to the left, thereby extending the overall length of the device. The extension amount of the adjusting handle 2 can be adjusted axially according to the processing needs. After the adjustment is completed, the screw 13 is reinstalled so that it is inserted into the corresponding through hole 14 to fix the position of the adjusting handle 2. At this time, the return spring 15 is back to the corresponding compressed state according to the actual position.
