Description

Technical Field

[0001] This utility model relates to the field of hanging fixture technology, and in particular to a hanging fixture for processing ring-shaped parts. Background Technology

[0002] In the machining of ring-shaped parts (such as bearing rings and annular flanges), hangers are often used to suspend and fix the ring-shaped workpieces to facilitate processes such as painting, electroplating, and heat treatment. The structural rationality of the hanger directly affects the machining efficiency and workpiece quality. However, existing hangers for ring-shaped part machining still have significant drawbacks: on the one hand, some hangers have a simple suspension structure design, which can only suspend a small number of ring-shaped workpieces at a time in a limited space, resulting in low space utilization and failing to meet the needs of batch processing, significantly restricting machining efficiency; on the other hand, some hangers use rigid clamping to fix the workpiece, lacking elastic adjustment capabilities, and are prone to hard contact with the surface of the ring-shaped workpiece during clamping, which can cause surface damage or scratches, compromising machining accuracy and surface quality; at the same time, the clamping dimensions of these hangers are mostly fixed specifications, making it difficult to flexibly adjust according to the different inner diameters, outer diameters, or heights of the ring-shaped workpieces, resulting in poor adaptability and failing to meet the diverse machining needs of ring-shaped parts.

[0003] Therefore, those skilled in the art have provided a fixture for machining ring-shaped parts to solve the problems mentioned in the background art. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a fixture for processing ring-shaped parts.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A fixture for processing ring-shaped parts includes a support frame. Multiple suspension rods are spaced apart on the inner side of the support frame. Multiple positioning sleeves are spaced apart on the outer side of each suspension rod along the vertical direction. Two positioning ring plates are fixedly connected at intervals at the upper and lower positions on the outer side of each positioning sleeve. Multiple positioning rods are evenly arranged in a ring array between the two positioning ring plates. A separator ring is fixedly fitted in the middle of each positioning rod. Movable blocks are movably fitted at the top and bottom ends of each positioning rod. A return spring is fitted on the outer side of each positioning rod between the separator ring and the two movable blocks. Workpiece clamping rods are fixedly connected to the ends of the two movable blocks away from the positioning rods, and are symmetrically arranged. The two workpiece clamping rods, in conjunction with the elastic force of the return springs, clamp and fix the ring-shaped workpiece to be processed.

[0007] Preferably, the workpiece clamping rod is bent sequentially in the direction away from the movable block to form an abutment part, a clamping part, and a barb part;

[0008] The side of the abutment near the annular workpiece is a vertical surface, and this vertical surface is in close contact with the axial end face of the annular workpiece. The clamping part is located inside the annular workpiece and is arched, with the apex of its arched structure in close contact with the inner wall of the annular workpiece. The barb is located at the end of the annular workpiece away from the abutment and is in close contact with the axial end face of that end of the annular workpiece.

[0009] Preferably, the top end of the upper positioning ring plate and the bottom end of the lower positioning ring plate are provided with radial threaded holes corresponding to each positioning rod. The locking screw is installed through the threaded hole. The top end and the bottom end of the positioning rod are provided with threaded positioning holes that are adapted to the locking screw. After one end of the locking screw passes through the threaded hole of the positioning ring plate, it is screwed into the threaded positioning hole.

[0010] Preferably, the top surface of the positioning ring plate below is provided with a plurality of U-shaped slots arranged in a ring array, and the plurality of U-shaped slots correspond one-to-one with a plurality of positioning rods.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0026] Reference Figure 1-7 A fixture for processing ring-shaped parts includes a support frame 1. Multiple suspension rods 2 are spaced apart on the inner side of the support frame 1. Multiple positioning sleeves 3 are spaced apart on the outer side of the suspension rods 2 along the vertical direction. Two positioning ring plates 4 are fixedly connected at intervals at the upper and lower positions on the outer side of the positioning sleeves 3. Multiple positioning rods 5 are evenly arranged in a ring array between the two positioning ring plates 4. A separator ring 51 is fixedly fitted in the middle of the positioning rod 5. Movable blocks 6 are movably fitted at the top and bottom of the outer side of the positioning rod 5. Return springs 7 are fitted between the separator ring 51 and the two movable blocks 6 on the outer side of the positioning rod 5. Workpiece clamping rods 8 are fixedly connected to the ends of the two movable blocks 6 away from the positioning rods 5, and are symmetrically arranged. The two workpiece clamping rods 8, in conjunction with the elastic force of the return springs 7, clamp and fix the ring-shaped workpiece 9 to be processed.

[0027] Using the above technical solution, this hanger provides stable support through the load-bearing frame 1. The positioning sleeves 3 are distributed at intervals along the vertical direction of the suspension rod 2, and their height can be flexibly adjusted to adapt to different processing requirements. The two positioning ring plates 4 fixed to the outside of the positioning sleeves 3 provide a stable mounting carrier for the positioning rods 5, and the multiple positioning rods 5 are distributed in a ring array, which can simultaneously suspend multiple ring-shaped workpieces 9 to be processed. The separator ring 51 in the middle of the positioning rod 5, together with the return spring 7 and the movable block 6 sleeved on the outside, form an elastic adjustment structure. When the ring-shaped workpiece 9 is placed between two symmetrical workpiece clamping rods 8, the elastic force of the return spring 7 can drive the movable block 6 to drive the workpiece clamping rods 8 to automatically clamp the ring-shaped workpiece 9, which not only ensures the clamping stability, but also avoids the damage to the workpiece surface caused by rigid clamping, and at the same time realizes the quick loading and unloading of the ring-shaped workpiece 9, improving processing efficiency.

[0028] The workpiece clamping rod 8 is bent sequentially in the direction away from the movable block 6 to form a stop part 81, a clamping part 82 and a barb part 83;

[0029] The side of the abutment 81 closest to the annular workpiece 9 is a vertical surface, and this vertical surface is in close contact with the axial end face of the annular workpiece 9. The clamping part 82 is located inside the annular workpiece 9 and is arched. The apex of its arched structure is in close contact with the inner wall of the annular workpiece 9. The barb part 83 is located at the end of the annular workpiece 9 away from the abutment 81 and is in close contact with the axial end face of that end of the annular workpiece 9.

[0030] Using the above technical solution, the abutment part 81, clamping part 82, and barb part 83 formed by bending the workpiece clamping rod 8 form a multi-dimensional limiting structure: the vertical surface of the abutment part 81 is in close contact with the axial end face of the annular workpiece 9, realizing the positioning of one end of the workpiece in the axial direction; the arched structure of the clamping part 82 is in close contact with the inner wall of the annular workpiece 9, enhancing the clamping stability through surface contact and preventing the workpiece from swaying radially; the barb part 83 is pressed against the axial end face of the annular workpiece 9 away from the abutment part 81, further restricting the axial displacement of the workpiece and preventing the annular workpiece 9 from falling off the workpiece clamping rod 8 during processing.

[0031] The top of the upper positioning ring plate 4 and the bottom of the lower positioning ring plate 4 are provided with radial threaded holes corresponding to each positioning rod 5. The locking screw 10 is installed through the threaded hole. The top and bottom of the positioning rod 5 are provided with threaded positioning holes 11 that are adapted to the locking screw 10. After one end of the locking screw 10 passes through the threaded hole of the positioning ring plate 4, it is screwed into the threaded positioning hole 11.

[0032] Using the above technical solution, the radial threaded holes of the upper positioning ring plate 4 and the lower positioning ring plate 4 cooperate with the locking screw 10, and together with the threaded positioning hole 11 of the positioning rod 5, the positioning rod 5 can be firmly fixed; unscrewing the locking screw 10 allows for quick disassembly of the positioning rod 5, facilitating subsequent maintenance and replacement of parts and reducing maintenance costs.

[0033] The top surface of the lower positioning ring plate 4 is provided with multiple U-shaped slots 12 arranged in a ring array, and the multiple U-shaped slots 12 correspond one-to-one with multiple positioning rods 5. The open end of the U-shaped slot 12 is connected to the outer peripheral wall of the positioning ring plate 4 along the radial direction. The bottom end of the positioning rod 5 can slide through the open end of the U-shaped slot 12 to the inner wall of the closed end of the U-shaped slot 12.

[0034] Using the above technical solution, the U-shaped slot 12 of the lower positioning ring plate 4 allows the bottom end of the positioning rod 5 to slide from the open end to the closed end, quickly completing the initial positioning; after positioning, it is fixed by locking screw 10 and threaded positioning hole 11, simplifying operation, improving the installation efficiency of positioning rod 5, and adapting to the scenario of batch assembly or frequent replacement of positioning rod 5.

[0035] The side wall of the positioning sleeve 3 is provided with a radial threaded hole, through which the fastening screw 13 is installed. The side of the suspension pole 2 is provided with a plurality of positioning holes 14 that are adapted to the fastening screw 13 at equal intervals along the vertical direction. One end of the fastening screw 13 can be inserted into the positioning hole 14 at the corresponding height.

[0036] Using the above technical solution, the fastening screw 13 of the positioning sleeve 3 cooperates with the positioning hole 14 of the suspension rod 2. After sliding the positioning sleeve 3 to a suitable height, the fastening screw 13 can be inserted to lock the position. Multiple positioning holes 14 make the height adjustment more flexible, which can adapt to ring-shaped workpieces 9 of different heights, and the position is stable after locking. At the same time, the positioning sleeve 3 can be disassembled by unscrewing the fastening screw 13, which makes it easy to increase or decrease the number of positioning sleeves 3 according to processing needs, improves the flexibility of the hanger, and meets the suspension processing needs of different batches of workpieces.

[0037] Multiple fixing rings 15 are installed at intervals on the bottom inner side of the load-bearing frame 1, and the inner diameter of the fixing rings 15 is adapted to the outer diameter of the suspension pole 2. The bottom end of the suspension pole 2 is movably inserted into the inner side of the fixing rings 15.

[0038] The top of the supporting frame 1 has through holes corresponding to the positions of each suspension pole 2. The connecting screw 16 moves through the through holes. The top of the suspension pole 2 has a threaded connection hole 17. The bottom end of the connecting screw 16 is threaded into the corresponding threaded connection hole 17.

[0039] Using the above technical solution, the fixing ring 15 at the bottom of the load-bearing frame 1 can radially position the bottom of the suspension pole 2 to prevent shaking during processing; the top connecting screw 16 is screwed into the threaded connection hole 17 of the suspension pole 2 to form a dual structure of "bottom positioning + top fixing", which further enhances the stability of the suspension pole 2; the suspension pole 2 can be disassembled by unscrewing the connecting screw 16, which is convenient for disassembly, transportation or replacement of parts.

[0040] Working principle:

[0041] First, the supporting frame 1 provides overall support. The bottom end of the suspension pole 2 is inserted into the fixing ring 15, and the top end is fixed with the connecting screw 16 to ensure the stability of the pole. Then, according to the processing requirements, the sliding positioning sleeve 3 is slid to a suitable height, and the position of the sleeve is locked by inserting the fastening screw 13 into the positioning hole 14. Then, the bottom end of the positioning rod 5 is slid into the U-shaped slot 12 of the lower positioning ring plate 4 and fixed with the threaded positioning hole 11 by the locking screw 10. When in use, the two symmetrical workpiece clamping rods 8 are pulled to compress the return spring 7 of the movable block 6. The annular workpiece to be processed 9 is placed between the clamping rods. After the clamping rods are released, the return spring 7 rebounds and drives the clamping rods to clamp the workpiece. At the same time, the abutment part 81, clamping part 82, and barb part 83 of the workpiece clamping rod 8 limit the workpiece from the axial and radial directions, respectively, so as to realize the stable suspension and processing of the annular workpiece to be processed.

[0042] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
