[0002] Ring-shaped parts refer to parts with a ring structure, which are commonly used in mechanical devices to serve functions such as connection, support, or sealing. For example, a spacer is a ring-shaped part used to maintain a specified axial distance between two bearing rings or bearing washers. In large mechanical equipment, ring-shaped parts such as slewing bearings and gear rings usually require high strength and high wear resistance. Roll forming technology can produce high-quality large mechanical ring parts, thereby improving the service life and reliability of the equipment. However, during the production and processing of ring-shaped parts, their surfaces often need to be ground or cut. To facilitate the processing of ring-shaped parts, clamping and positioning fixtures are often used to fix the ring-shaped parts.

[0003] When using related clamping and positioning fixtures, the ring-shaped part is usually placed on the base of the fixture, and then the clamps, which are arranged in a triangular or cross shape, are contracted and closed to achieve the effect of clamping and fixing the outer side of the ring-shaped part.

[0004] However, when using the above method, contact with the annular part is unavoidable during clamping and positioning. This contact can obstruct the surface processing of the annular part, thus affecting its normal processing.

[0022] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0023] This application discloses a clamping and positioning fixture for annular parts. (Refer to...) Figure 2 Figure 3 A clamping and positioning fixture for annular parts includes a base 1 and an annular part body 2, wherein the annular part body 2 is located on top of the base 1, and further includes...

[0024] The double-sided fixing mechanism 3 is located on the top of the base 1 and is used to adjust, clamp and position the inner and outer sides of the annular part body 2.

[0025] The double-sided fixing mechanism 3 includes a fixing platform 301, a plurality of fixing clamps 302 and a plurality of double-sided clamping components 5. The bottom of the fixing platform 301 is mounted on the top of the base 1 through a rotating mechanism 8. The bottom of the plurality of fixing clamps 302 is mounted on the top of the fixing platform 301 through a moving adjustment component 4. The plurality of double-sided clamping components 5 are respectively mounted on the side walls of the plurality of fixing clamps 302.

[0026] The movable adjustment assembly 4 includes several movable slides 401, several adjusting screws 402, several movable sliders 403, and several threaded holes 404. The several movable slides 401 are evenly distributed on the top of the fixed platform 301. The several adjusting screws 402 are rotatably connected to the two ends of the several movable slides 401 by rotating through the side wall of the fixed platform 301. The several threaded holes 404 are respectively opened in the middle of the several movable sliders 403. The several movable sliders 403 are rotatably connected to the side wall of the several adjusting screws 402 by the several threaded holes 404. The bottom of the several fixing clips 302 are respectively fixedly connected to the top of the several movable sliders 403.

[0027] The double-sided clamping assembly 5 includes several stabilizing clamps 501 and a rotating assembly 6. One end of each stabilizing clamp 501 is mounted to the side wall of the fixed clamp 302 via the rotating assembly 6.

[0028] The rotary assembly 6 includes several support frames 601, several rotating blocks 602, and several torsion springs 603. One end of each support frame 601 is symmetrically fixed to the side wall of the fixed clamp 302. One end of each stabilizing clamp 501 is rotatably connected to the middle of the other end of each support frame 601 through several rotating blocks 602. The two ends of each torsion spring 603 are fixedly connected to the side walls of the support frames 601 and the side walls of the rotating blocks 602, respectively.

[0029] The double-sided fixing mechanism 3 also includes an anti-slip component 7, which is installed at both ends of a plurality of fixing clips 302. The anti-slip component 7 includes a plurality of first soft pads 701 and a plurality of second soft pads 702. The plurality of first soft pads 701 are respectively fixedly connected to both ends of a plurality of fixing clips 302, and the plurality of second soft pads 702 are respectively fixedly connected to the side walls of a plurality of stabilizing clamps 501. The plurality of first soft pads 701 and the plurality of second soft pads 702 are made of rubber.

[0030] In this embodiment, firstly, the adjusting screw 402 is rotated to make it rotate within the movable slide groove 401 opened on the top of the fixed platform 301. The rotation of the adjusting screw 402 causes the movable slider 403, rotatably connected via the threaded hole 404, to move back and forth on the adjusting screw 402 under the constraint of the movable slide groove 401. The back-and-forth movement of the movable slider 403 on the adjusting screw 402 causes the connected fixing clamp 302 to move back and forth on the top of the fixed platform 301, opening or closing. At this time, according to the processing requirements of the annular part body 2, when processing of the outer surface of the annular part body 2 is required, simply rotating the adjusting screw 402 causes the movable slider 403 to move and drive the fixing clamp 302 within the fixed platform 301. The top of the platform 301 moves and closes, then the annular part body 2 is placed on the platform 301. The adjusting screw 402 is then rotated in the opposite direction to open the fixing clamps 302. The evenly distributed triangular fixing clamps 302 open and close, allowing force to be applied to the annular part body 2 from the inside for fixation and positioning. This facilitates the processing of the outer surface of the annular part body 2. Similarly, when processing the inner surface of the annular part body 2, simply rotate the adjusting screw 402 to open the fixing clamps 302 at the top of the platform 301, place the annular part body 2 in the middle of the platform 301, and then rotate the adjusting screw 402 in the opposite direction to open the fixing clamps 302. When the clamping clamp 302 is closed, a force can be applied from the outside of the annular part body 2 for clamping and positioning, thereby allowing for sufficient processing of the inner side of the annular part body 2. Simultaneously, when the clamping clamp 302 clamps and positions the inner and outer sides of the annular part body 2, the supporting frame 601 supports the rotating stabilizing clamp 501, causing it to rotate and open at the center of the supporting frame 601 via the rotating block 602. After the clamping clamp 302 contacts the annular part body 2, the torsion spring 603 provides a reaction force, causing the stabilizing clamp 501 to rotate. This rotation of the stabilizing clamp 501 increases the contact area with the annular part body 2, thereby further processing the inner or outer side of the annular part body 2. The clamping is secure, and the first soft pad 701 and the second soft pad 702 are attached to the annular part body 2 by the fixing clamp 302 and the stabilizing clamp 501. At this time, the first soft pad 701 and the second soft pad 702, which are made of rubber, can provide elastic contact and wear protection for the annular part body 2, while increasing the friction between the fixing clamp 302 and the stabilizing clamp 501 and the annular part body 2 to prevent slipping and stabilize. In this way, it is possible to securely clamp and fix the inner and outer sides of the annular part body 2 according to the processing needs, thereby avoiding obstruction to the processing of the surface of the annular part body 2 and effectively facilitating the full processing of the surface of the annular part body 2.

[0031] Furthermore, the rotating mechanism 8 includes a supporting shaft 801, a first gear 802, a motor 803, and a second gear 804. The bottom of the supporting shaft 801 is rotatably connected to the top center of the base 1, the bottom of the fixed platform 301 is fixedly connected to the top of the supporting shaft 801, the first gear 802 is fixedly connected to the side wall of the supporting shaft 801, the motor 803 is fixedly connected to the top of the base 1, and the second gear 804 is fixedly connected to the output end of the motor 803, and the side wall of the second gear 804 meshes with the side wall of the first gear 802.

[0032] Based on the above embodiment, after clamping and positioning the annular part body 2, the motor 803 is activated to provide force to drive the second gear 804 connected to it to rotate. The rotation of the second gear 804 drives the first gear 802 meshing with it to rotate as well. The rotation of the first gear 802 drives the support shaft 801 connected to it to rotate at the top of the base 1. The rotation of the support shaft 801 drives the fixed platform 301 to rotate in the horizontal direction. The rotation of the fixed platform 301 then drives the fixed annular part body 2 to rotate in the horizontal direction. This allows for easy adjustment of the processing angle of the annular part body 2 according to processing needs, thereby further facilitating the surface processing of the annular part body 2.

[0033] The implementation principle of the ring-shaped part clamping and positioning fixture in this application embodiment is as follows: In use, firstly, by rotating the adjusting screw 402, it rotates within the movable slide groove 401 opened on the top of the fixed platform 301. The rotation of the adjusting screw 402 causes the movable slider 403, rotatably connected through the threaded hole 404, to move back and forth on the adjusting screw 402 under the limitation of the movable slide groove 401. The back-and-forth movement of the movable slider 403 on the adjusting screw 402 drives the connected fixed clamp 302 to move back and forth on the top of the fixed platform 301, opening or closing. At this time, according to the processing requirements of the ring-shaped part body 2, when it is necessary to process the outer surface of the ring-shaped part body 2, simply rotate the adjusting screw 402 to move the movable slider 403... 03. Under force, the fixing clamp 302 moves and closes on the top of the fixing platform 301. Then, the annular part body 2 is placed on the fixing platform 301. The fixing clamp 302 is then moved and opened by rotating the adjusting screw 402 in the opposite direction. The evenly distributed triangular fixing clamps 302 open and close, allowing force to be applied to the annular part body 2 from the inside, thus fixing and positioning it. This facilitates the processing of the outer surface of the annular part body 2. Similarly, when processing the inner surface of the annular part body 2, simply rotate the adjusting screw 402 to move and open the fixing clamp 302 on the top of the fixing platform 301, place the annular part body 2 in the middle of the fixing platform 301, and then rotate the adjusting screw 402 in the opposite direction. By moving the fixing clamp 302 in the opposite direction to close it, a force can be applied from the outside of the annular part body 2 for clamping and positioning. This allows for sufficient processing of the inner side of the annular part body 2. Simultaneously, while the fixing clamp 302 clamps and positions the inner and outer sides of the annular part body 2, the support frame 601 supports and rotates the stabilizing clamp 501, causing it to open via the rotating block 602 at the center of the support frame 601. After the fixing clamp 302 contacts the annular part body 2, the torsion spring 603 provides a reaction force, causing the stabilizing clamp 501 to rotate. This rotation increases the contact area with the annular part body 2, further stabilizing and clamping the inner or outer side of the annular part body 2. The fixing clamp 302 and the stabilizing clamp 501 are attached to the annular part body 2, so that the first soft pad 701 and the second soft pad 702 are attached to the annular part body 2. At this time, the first soft pad 701 and the second soft pad 702, which are made of rubber, can provide elastic contact and wear-resistant protection for the annular part body 2, while increasing the friction between the fixing clamp 302 and the stabilizing clamp 501 and the annular part body 2 to prevent slippage and stabilize it. In this way, it is possible to effectively and conveniently clamp and fix the inner and outer sides of the annular part body 2 according to the processing needs, thereby avoiding obstruction to the processing of the surface of the annular part body 2 and effectively facilitating the full processing of the surface of the annular part body 2. Secondly, after clamping and positioning the annular part body 2,The motor 803 provides force to drive the second gear 804, which in turn rotates. This rotation of the second gear 804, in turn, drives the first gear 802, which in turn rotates. The first gear 802, in turn, drives the supporting shaft 801, which rotates at the top of the base 1. This rotation of the supporting shaft 801, in turn, drives the fixed platform 301 to rotate horizontally. This rotation of the fixed platform 301, in turn, drives the fixed annular part body 2 to rotate horizontally. This allows for easy adjustment of the annular part body 2's rotation angle according to processing needs, thus facilitating surface machining of the annular part body 2.

[0034] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
