Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of mechanical processing, in particular to a turning tool device. Background Art
[0002] In the field of mechanical processing, turning workpieces with different planes often requires multiple clamping of the workpiece. For example, when machining two opposing planes, the typical process is to first clamp the workpiece, turn one of the planes, and then re-clamp the workpiece to turn the other plane.
[0003] However, since it's difficult to maintain the exact same position and clamping state between clamping steps, clamping errors can occur. This error inevitably affects the workpiece's machining accuracy, particularly the parallelism between two opposing planes. Therefore, even if a high degree of precision can be achieved during each machining of a single plane when a second clamping step is required, the parallelism of the final product may still not meet design requirements. This can lead to reduced machining quality, increased rework rates, and increased production costs and machining difficulty.

[0036] The following describes embodiments of the present invention in detail. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.
[0037] like Figures 1 to 4 As shown, the turning tool device provided in this embodiment is used for turning a workpiece 100, wherein the workpiece 100 has a center hole 110, and the workpiece 100 includes a first plane 120 and a second plane 130, and the first plane 120 and the second plane 130 are respectively located at opposite ends of the workpiece 100 along the central axis of the center hole 110. For example, the workpiece 100 can be a flange, and the center of the flange has a hole for inserting a pipe or a shaft, namely the center hole 110. Further, as Figure 1 and Figure 2 As shown, the flange can be a stepped structure including a large diameter section and a small diameter section. The first plane 120 corresponds to the small plane at the end face of the small diameter section, and the second plane 130 corresponds to the large plane at the end face of the large diameter section. The small plane and the large plane are arranged back to back.
[0038] The turning tool assembly includes a first turning tool 200 and a second turning tool (not shown). The first turning tool 200 is disposed through the center hole 110 and is used to turn the first plane 120. The second turning tool is disposed on a side of the second plane 130 away from the first plane 120 along the central axis of the center hole 110 and is used to turn the second plane 130.
[0039] During specific implementation, the workpiece 100 is first clamped and fixed on the lathe, and then the first turning tool 200 and the second turning tool are installed so that the first turning tool 200 is inserted into the center hole 110 of the workpiece 100. After the turning tool device is installed, the positions of the first turning tool 200 and the second turning tool are further fine-tuned so that the first turning tool 200 abuts against the first plane 120 and the second turning tool abuts against the second plane 130. Then, the workpiece 100 begins to rotate around the central axis of the center hole 110. During the rotation of the workpiece 100, the first turning tool 200 and the second turning tool perform turning processing. In addition, the first turning tool 200 and the second turning tool can also perform turning processing in sequence. For example, the second turning tool first turns the second plane 130, and after the second plane 130 is turned, the first turning tool 200 turns the first plane 120. The specific process can be determined according to actual conditions.
[0040] The second turning tool is not shown in the figure and can be designed according to a conventional turning tool. The lathe and the structure of the turning tool device for adjusting the position on the lathe are mature existing technologies in the field and will not be described in detail here.
[0041] The turning tool device provided in this embodiment, by setting a first turning tool 200 and a second turning tool, can enable the workpiece 100 to turn the relative first plane 120 and second plane 130 in one clamping, avoiding the clamping error caused by secondary clamping in the traditional processing process, thereby effectively improving the parallelism accuracy between the processed first plane 120 and the second plane 130, which is beneficial to improving product quality and reducing production costs.
[0042] In addition, the clamping position of the lathe for the workpiece 100 is generally located at the outer edge of the workpiece 100. The arrangement of the first turning tool 200 passing through the center hole 110 can avoid interference between the first turning tool 200 and the clamping components.
[0043] In some embodiments, the workpiece 100 is clamped and rotated using a chuck, with the first flat surface 120 oriented toward the chuck. The chuck is typically mounted at the front end of a lathe spindle, rotating the spindle to drive the workpiece 100 for turning. This arrangement allows for fast and stable clamping of the workpiece 100.
[0044] Specifically, the chuck is a three-jaw chuck, which can evenly apply clamping force to the workpiece 100 , effectively reducing vibration and displacement of the workpiece 100 during machining, and ensuring the stability of the workpiece 100 .
[0045] In some embodiments, after the workpiece 100 is clamped, the runout error of the second plane 130 is configured to be within 0.1 mm.
[0046] By adjusting the runout error of the second plane 130 by dialing and controlling the runout error within a smaller range, it helps to reduce subsequent processing errors caused by runout, ensure that the workpiece 100 maintains good parallelism and surface quality during the turning process, and improve the overall processing accuracy.
[0047] In some embodiments, the first turning tool 200 and the second turning tool are mounted on the same tool holder.
[0048] With such an arrangement, the first turning tool 200 and the second turning tool share the same tool holder, and there is no need to configure an independent tool holder for each turning tool, which simplifies the structural design and reduces the complexity of the equipment.
[0049] like Figure 4 As shown, in some embodiments, the first turning tool 200 includes a tool holder 210 and a blade 220 . The blade 220 is detachably mounted on the tool holder 210 . The tool holder 210 is passed through the central hole 110 . The blade 220 is configured to turn the first plane 120 .
[0050] Through such a setting, the handle 210 provides a stable support for the blade 220. In addition, the separate design of the handle 210 and the blade 220 makes the replacement and adjustment of the blade 220 more flexible, making it convenient to replace the blade 220 according to different workpieces or processing requirements to adapt to different processing tasks.
[0051] Optionally, the blade 220 is connected to the handle 210 via a threaded fastener. The threaded fastener can be a screw, a bolt, etc., which is not specifically limited here.
[0052] By providing the threaded fastener, reliable connection stability can be provided for the blade 220 , and the installation and removal of the blade 220 can be made simple and quick.
[0053] Furthermore, the handle 210 includes a first segment 211 and a second segment 212, which are L-shaped. The first segment 211 is passed through the center hole 110, the second segment 212 is connected to the first segment 211, and the blade 220 is installed at the end of the second segment 212 away from the first segment 211.
[0054] Through such a setting, the L-shaped structure can make the second section 212 of the handle 210 extend in a direction parallel to the first plane 120, so that the blade 220 installed on the second section 212 can contact the first plane 120 more smoothly for cutting, thereby optimizing the cutting angle and reducing the cutting resistance.
[0055] like Figure 3 As shown, in some embodiments, the contact portion of the blade 220 with the first plane 120 is tilted relative to the first plane 120 .
[0056] Through such a setting, the inclination angle can allow different parts of the blade 220 to participate in cutting in sequence, rather than making the same point always bear the cutting load. In this way, the blade 220 can be evenly worn and the service life of the blade 220 can be extended.
[0057] In some embodiments, the blade 220 is configured as an alloy blade.
[0058] The alloy blades have high hardness and wear resistance and can remain sharp during high-speed cutting, thereby improving cutting efficiency and reducing processing time.
[0059] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. A person skilled in the art will be able to make other variations or modifications based on the above description. It is not necessary and impossible to enumerate all implementation methods here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the claims of the present invention.
