Description

Technical Field

[0001] This utility model relates to the field of ultra-precision turning technology, specifically to a tooling structure for ultra-precision turning. Background Technology

[0002] Ultra-precision turning is a machining process that uses high-precision lathes and specially designed cutting tools to precisely control the tool's motion trajectory and cutting parameters to perform micro-cutting on the workpiece, thereby achieving sub-micron level machining accuracy and nano-level surface roughness.

[0003] The tool holder is an important tooling structure in ultra-precision turning. It is a device used to support the cutting tool and its function is to fix the tool and provide stable cutting conditions to remove material from the workpiece. The tool holder can achieve turning operations of different shapes and sizes by adjusting the angle, position and cutting parameters. The stability and adjustability of the tool holder are crucial to obtaining high-quality turning results. However, when using existing tooling structures for ultra-precision turning, the installation and removal of the cutting tool are relatively inconvenient due to the need to tighten multiple sets of bolts to fix the cutting tool, which affects the efficiency of workpiece machining.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a tooling structure for ultra-precision turning, comprising:

[0006] The frame, including the turning tool holder;

[0007] The clamping mechanism includes an adjusting handle that acts on the surface of a turning tool holder. A connecting rod is fixedly connected to the surface of the adjusting handle. A clockwise threaded rod is fixedly connected to the end of the connecting rod away from the adjusting handle. A limit rod is fixedly connected to the end of the clockwise threaded rod away from the connecting rod. A counterclockwise threaded rod is fixedly connected to the end of the limit rod away from the clockwise threaded rod. An adjusting block is threadedly sleeved onto the surface of the clockwise threaded rod. A first connecting shaft is fixedly connected to the surface of the adjusting block. A connecting hinge is sleeved onto the surface of the first connecting shaft. A second connecting shaft is sleeved onto the end of the connecting hinge away from the first connecting shaft.

[0024] 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.

[0025] Please see Figure 1-5 One embodiment provided by this utility model:

[0026] A tooling structure for ultra-precision turning, comprising:

[0027] The frame includes the turning tool holder 1, which is an existing product and is not considered a technical protection point of this application. Therefore, it will not be described in detail here.

[0028] The clamping mechanism includes an adjusting handle 2, which acts on the surface of the turning tool holder 1 to drive the clockwise threaded rod 22 and the counterclockwise threaded rod 24 to rotate. A connecting rod 21 is fixedly connected to the surface of the adjusting handle 2 to connect the clockwise threaded rod 22. The end of the connecting rod 21 away from the adjusting handle 2 is fixedly connected to the clockwise threaded rod 22 to drive the adjusting block 25 to move. A limit rod 23 is fixedly connected to the end of the clockwise threaded rod 22 away from the connecting rod 21 to limit the movement position of the adjusting block 25. The end of the limit rod 23 away from the clockwise threaded rod 22 is fixedly connected to the limit rod 23. A counterclockwise threaded rod 24 is fixedly connected to drive the adjusting block 25 to move. The surface of the clockwise threaded rod 22 is threadedly fitted with the adjusting block 25 to drive the connecting hinge rod 27 to rotate. The surface of the adjusting block 25 is fixedly connected to a first connecting shaft 26 to connect the connecting hinge rod 27. The surface of the first connecting shaft 26 is fitted with the connecting hinge rod 27 to drive the pressure plate 29 to move. The end of the connecting hinge rod 27 away from the first connecting shaft 26 is fitted with a second connecting shaft 28 to connect the connecting hinge rod 27. The surface of the second connecting shaft 28 is fixedly connected to a pressure plate 29 to press the turning tool.

[0029] Furthermore, the connecting rod 21 is internally connected to the turning tool holder 1 via the adjusting handle 2, the clockwise threaded rod 22 is rotatably connected to the surface of the turning tool holder 1 via the connecting rod 21, and the counterclockwise threaded rod 24 is rotatably connected to the surface of the turning tool holder 1 via the limiting rod 23. Rotating the adjusting handle 2 can drive the connecting rod 21, the clockwise threaded rod 22, the limiting rod 23, and the counterclockwise threaded rod 24 to rotate synchronously.

[0030] Furthermore, the adjusting blocks 25 are in two sets. The adjusting blocks 25 are threaded onto the surface of the counterclockwise threaded rod 24. The adjusting blocks 25 are movably connected to the surface of the turning tool holder 1 via the clockwise threaded rod 22 and the counterclockwise threaded rod 24. The thread grooves on the surfaces of the clockwise threaded rod 22 and the counterclockwise threaded rod 24 rotate in opposite directions, so that the two sets of adjusting blocks 25 move towards each other on the surfaces of the clockwise threaded rod 22 and the counterclockwise threaded rod 24.

[0031] Furthermore, the first connecting shaft 26 is symmetrically distributed in two sets on both sides of the adjusting block 25, and the connecting hinge rod 27 is in two sets. The connecting hinge rod 27 is rotatably connected to the surface of the adjusting block 25 and the first connecting shaft 26. The movement of the adjusting block 25 drives the connecting hinge rod 27 to rotate and move on the surface of the first connecting shaft 26, thereby causing the pressure plate 29 to move downward.

[0032] Furthermore, the second connecting shafts 28 are symmetrically distributed in two sets on the surface of the pressure plate 29. The second connecting shafts 28 are movably connected to the surface of the turning tool holder 1 through the connecting hinge 27. The pressure plate 29 is movably connected to the surface of the turning tool holder 1 through the second connecting shafts 28. The rotation of the connecting hinge 27 drives the second connecting shafts 28 to move downward, thereby driving the pressure plate 29 to move downward and press the turning tool.

[0033] Furthermore, the positioning mechanism includes a support plate 3, which is fixedly connected to the surface of the turning tool holder 1 and is used to connect the first clamping plate 31. The first clamping plate 31 is fixedly connected to the surface of the support plate 3 and is used to clamp and position the longer workpiece to be processed in conjunction with the adjusting knob 34. The first clamping plate 31 is rotatably connected to a limit shaft 32 to limit the position of the adjusting threaded rod 33. The adjusting threaded rod 33 is fixedly connected to the surface of the limit shaft 32 and is used to drive the second clamping plate 35 to move. The end of the adjusting threaded rod 33 away from the limit shaft 32 is fixedly connected to the adjusting knob 34 and is used to drive the adjusting threaded rod 33 to rotate. The surface of the adjusting threaded rod 33 is threadedly sleeved with the second clamping plate 35 and is used to clamp and position the longer workpiece to be processed in conjunction with the first clamping plate 31.

[0034] Furthermore, the adjusting threaded rod 33 is rotatably connected to the surface of the first clamping plate 31 via the adjusting knob 34, and the limiting shaft 32 is rotatably connected to the inside of the first clamping plate 31 via the adjusting threaded rod 33. Rotating the adjusting knob 34 can drive the adjusting threaded rod 33 and the limiting shaft 32 to rotate synchronously. The limiting shaft 32 rotates inside the first clamping plate 31, limiting the rotation position of the adjusting threaded rod 33.

[0035] Furthermore, the second clamping plate 35 is abutted and connected to the surface of the support plate 3. The second clamping plate 35 is movably connected to the surface of the support plate 3 through the adjusting threaded rod 33. The second clamping plate 35 is abutted and connected to the surface of the first clamping plate 31 through the adjusting threaded rod 33. The rotation of the adjusting threaded rod 33 drives the second clamping plate 35 to move on the surface of the support plate 3, thereby abutting and clamping the front end of the long workpiece to avoid shaking during processing.

[0036] Working principle: When using the turning tool holder 1, first place the tool to be used under the pressure plate 29. Then, turn the adjusting handle 2 to drive the connecting rod 21, the clockwise threaded rod 22, the limiting rod 23, and the counterclockwise threaded rod 24 to rotate synchronously. The thread grooves on the surfaces of the clockwise threaded rod 22 and the counterclockwise threaded rod 24 turn in opposite directions, causing the two sets of adjusting blocks 25 to move towards each other on the surfaces of the clockwise threaded rod 22 and the counterclockwise threaded rod 24. The movement of the adjusting blocks 25 causes the connecting hinge rod 27 to rotate and move on the surface of the first connecting shaft 26, which in turn causes the second connecting shaft 28 to move downward, thereby causing the pressure plate 29 to move downward and clamp the turning tool, completing the installation of the turning tool. If the workpiece to be processed is too long, the adjusting knob 34 needs to be turned to drive the adjusting threaded rod 33 and the limiting shaft 32 to rotate synchronously, causing the second clamping plate 35 to move on the surface of the support plate 3, thereby clamping the front end of the longer workpiece and preventing it from shaking during processing.

[0037] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
