[0020] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0021] Exemplary embodiments will be described in detail herein, with examples illustrated in the accompanying drawings. In the following description, when referring to the drawings, identical numerals in different figures represent identical or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments are not intended to represent all embodiments consistent with the present application. Rather, they are merely examples of devices consistent with certain aspects of the present application, as detailed in the appended claims.

[0022] The terms used in this application are for the purpose of describing specific embodiments only and are not intended to limit this application. Unless otherwise defined, technical or scientific terms used in this application should have the same ordinary meaning as those understood by persons of ordinary skill in the art to which this invention belongs. The use of "a," "an," and similar terms in this specification and claims does not indicate a limitation of quantity, but rather indicates the presence of at least one. "A plurality" includes two and is equivalent to at least two. "Includes" or "comprising" and similar terms mean that the elements or objects preceding "includes" or "comprising" include the elements or objects listed after "includes" or "comprising," and their equivalents, and do not exclude other elements or objects. "Connected" or "connected" and similar terms are not limited to physical or mechanical connections and may include electrical connections, whether direct or indirect. As used in this specification and the appended claims, the singular forms "a," "the," and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise. It should also be understood that the term "and / or" as used herein refers to and encompasses any and all possible combinations of one or more of the associated listed items.

[0023] Please refer to Figure 2-4 A fixture suitable for processing ring-shaped parts of various sizes includes a main body 1, which has an inner cavity 2 provided therein. The inner cavity 2 extends from one end of the main body 1 to the other end. A support 3 is installed at the bottom of the main body 1 and is fixed to the bottom of the main body 1 by a countersunk screw. The support 3 is partially located in the inner cavity 2. A screw 4 is installed in the inner cavity 2 and runs transversely through the support 3. A slider 5 is installed at each end of the screw 4. A connecting plate 6 is installed on the top of each slider 5. A clamp 7 is installed on the top of each connecting plate 6. The clamp 7 is a half-moon structure with the convex surface of the clamp 7 facing outward. The outward expansion of the two clamps 7 can tighten ring-shaped parts of different sizes.

[0024] Furthermore, the screw rod 4 is provided with opposite threads at both ends. Assuming that the left end of the screw rod 4 is provided with a left-hand thread, the right end is provided with a right-hand thread. Nuts 8 that match the threads of the screw rod 4 are installed inside the two sliders 5. The two nuts 8 are respectively mounted on both ends of the screw rod 4. That is, the nut 8 installed on the left end of the screw rod 4 is adapted to the left-hand thread, and the nut 8 installed on the right end of the screw rod 4 is adapted to the right-hand thread. Based on this design, by rotating the screw rod 4, the two sliders 5 (clamping plate 7) can be moved toward or away from each other, thereby tightening ring-shaped parts of different sizes.

[0025] Furthermore, a baffle 9 is installed at the bottom of each of the two connecting plates 6. The baffle 9 is a concave structure. The design of the baffle 9 can play a role in dust and chip prevention, and can prevent waste chips generated during the processing of the ring-shaped part from entering the inner cavity 2 and affecting the rotation of the screw 4.

[0026] Furthermore, the two baffles 9 are at different heights, that is, one baffle 9 is higher than the other baffle 9. By designing the high and low baffles 9, interference during the movement of the baffles 9 can be eliminated.

[0027] Furthermore, a guide groove 10 is provided on each side wall of the inner cavity 2 of the main body 1, which passes through both ends of the main body 1. A guide block 11 is provided on each side wall of the slider 5. The guide block 11 is located in the guide groove 10, and the guide block 11 is adapted to the guide groove 10 to play a guiding role.

[0028] Furthermore, a threaded hole 12 is formed on the same straight line between the main body 1 and the support 3. The central axis of the threaded hole 12 is perpendicular to the inner cavity 2. A thumb bolt 13 is installed in the threaded hole 12. When the thumb bolt 13 is tightened, that is, when the thumb bolt 13 is tightened until it interferes with the screw rod 4, the rotation of the screw rod 4 is restricted. In other words, the rotation of the screw rod 4 can be restricted by tightening or loosening the thumb bolt 13.

[0029] The utility model is a clamp suitable for processing ring-shaped parts of multiple sizes. Its working principle is explained in conjunction with the accompanying drawings:

[0030] First, place the ring-shaped piece on the connecting plate 6 and on the outside of the clamping plate 7. Then, use a wrench to rotate the screw 4. With the cooperation of the screw 4 and the nut 8, the slider 5, the connecting plate 6, and the clamping plate 7 can be driven to expand outward until the outer wall of the clamping plate 7 is tightly fitted with the inner wall of the ring-shaped piece. The ring-shaped piece is tightened and easy to process on the processing equipment. Changing the spacing between the two clamping plates 7 can adapt to ring-shaped pieces of different sizes, which has a wide range of applications.

[0031] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention. Such changes and improvements are intended to fall within the scope of the present invention. The scope of protection claimed in this invention is defined by the appended claims and their equivalents.
