Description

Technical Field

[0001] The utility model relates to the technical field of parts processing, and more specifically, to a clamping tool. In addition, the utility model also relates to a turning device comprising the clamping tool. Background Art

[0002] Disc thin-walled parts made of stainless steel have the characteristics of low rigidity, high plasticity (commonly known as high viscosity) and are not easy to turn. When clamping disc thin-walled parts, they are easily deformed under the action of the clamping force of the claws. For example, when clamping a thin-walled round tube, a slightly larger clamping force will flatten the thin-walled round tube. When the disc thin-walled parts are processed on a CNC lathe, they are fixed and clamped by the lathe claws, and the disc thin-walled parts rotate at high speed. The turning tool approaches the disc thin-walled parts and then contacts them, thereby turning the inner and outer cylindrical surfaces. In the processing of disc thin-walled parts, because the wall of the part is relatively thin, the hollow depth is large, and the rigidity is low, the turning tool approaches the part and contacts the thin wall of the part to apply a cutting force to the thin wall of the part. Affected by the cutting force, coupled with the insufficient rigidity of the disc thin-walled parts, the thin wall is prone to deformation or vibration. The vibration increases the surface roughness of the disc thin-walled parts, and a coarser turning texture appears, which affects the shape accuracy and surface roughness of the disc thin-walled parts, resulting in unqualified disc thin-walled parts.

[0003] In summary, how to improve the qualified rate of disc thin-wall parts after processing is a problem that needs to be solved urgently by technical personnel in this field. Utility Model Content

[0036] For details, please refer to the attached Figure 1 With attached Figure 2The disc thin-wall component 3 is an annular member, and a plurality of limiting holes 4 are arranged on its inner circumference.

[0040] Specifically, the support block 6 is fixed to the outer peripheral side of the clamping disc 1, and the upper end of the support block 6 is connected to the second tightening bolt 7. The operating principle of the second tightening bolt 7 is the same as that of the first tightening bolt 5. The difference is that the length of the second tightening bolt 7 is shorter than that of the first tightening bolt 5. The second deposit bolt 7, the first tightening bolt 5 and the locking assembly 2 cooperate to complete the clamping and positioning of the disc thin-walled assembly 3.

[0044] Specifically, the locking bolt is rotatably arranged on the clamping disc 1 , and after the limiting hole 4 on the disc thin-wall component 3 is aligned with the locking bolt, the locking bolt is rotated from the back of the clamping disc 1 to achieve the positioning of the disc thin-wall component 3 .

[0045] On the basis of the above embodiment, three locking assemblies 2 are provided, and three limiting holes 4 are correspondingly provided.

[0046] Specifically, when locking bolts are selected for the locking assembly 2, the number thereof should be set within a reasonable range to avoid a large workload in the locking process due to a large number of locking assemblies 2, and also to prevent loose locking due to a small number of locking assemblies 2.

[0047] Based on the above embodiment, six first clamping assemblies are provided and eight second clamping assemblies are provided.

[0048] Specifically, the inner circumference of the disk thin-wall component 3 is smaller than the outer circumference, so the number of clamping components required inside the disk thin-wall component 3 is less than the number of clamping components required on the outer circumference, preferably six first clamping components and eight second clamping components.

[0049] In addition to the above-mentioned clamping tool, the present invention also provides a turning device including the clamping tool disclosed in the above-mentioned embodiment and a CNC lathe.
