Description

Technical Field

[0001] This utility model relates to the field of machining technology, and in particular to a universal fixture for irregularly shaped parts with a quick-switchable clamping module. Background Technology

[0002] In the field of machining, clamping irregularly shaped parts, such as shafts with curved surfaces, asymmetrical plate parts, and parts with complex curved surfaces, often presents some challenges. Existing fixtures have certain limitations in application: traditional fixtures are often highly specialized and lack versatility. For example, V-type fixtures are mostly suitable for shaft parts, and flat fixtures are mostly suitable for plate parts. When dealing with a variety of irregularly shaped parts, it is often necessary to frequently change the entire set of fixtures, which is not only cumbersome to operate, but may also increase equipment investment costs. Although some combination fixtures support module replacement, it usually requires steps such as removing bolts and adjusting locating pins. The time spent on each switch may have a certain impact on the processing cycle. For irregular curved parts, conventional rigid fixtures are difficult to fit the surface of the parts, which can easily lead to loose clamping, deformation of the parts, and thus affect the machining accuracy.

[0003] Therefore, there is currently a demand in the industry for general-purpose fixtures that integrate multiple clamping functions, are easy to switch between, and have good adaptability, in order to better address the problems of multiple fixtures, slow switching, and the need to improve stability in the processing of irregular parts. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a universal clamping fixture for irregularly shaped parts that allows for quick switching of clamping modules.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A universal clamping fixture for irregularly shaped parts with quick-switchable clamping modules includes a plate body. Each plate body has a frame at one and another end. Two frames are rotatably connected by shafts. Each shaft is fixedly connected to a first block. Each first block is fixedly connected to a second block at one and another end. Each second block has a V-shaped groove. Each first block is fixedly connected to a frame. Multiple rods are equidistantly inserted through each frame. A first spring is fixedly connected between each rod and its corresponding frame. A sleeve is fixedly connected to one and another end of each plate body.

[0006] Preferably, the plate is rotatably connected to a double-ended screw, the double-ended screw is threadedly connected to two sleeves, and a handle is fixedly connected to one end and the other end of the double-ended screw. The double-ended screw is fitted with multiple corrugated tubes, and one end and the other end of the multiple corrugated tubes are respectively fixedly connected to the plate or sleeve.

[0007] Preferably, each of the two shafts has a through-hole rod, both of the through-hole rods are U-shaped, and each of the two through-hole rods has a second spring sleeved on one end and the other end of each of the two second springs respectively fixedly connected to the corresponding shaft and through-hole rod. Each of the two frames has multiple holes, and the two through-hole rods are respectively inserted into the corresponding holes.

[0008] Preferably, a sliding rod is fixedly connected to one end of the plate, and the sliding rod is slidably connected to the other two sleeves.

[0009] Preferably, each of the second blocks is fixedly connected with a rubber pad.

[0010] Preferably, each of the multiple rods is fixedly connected to a rubber block, and the rubber block is hemispherical.

[0011] Preferably, each of the four corners of the plate is fixedly connected to a base.

[0012] The beneficial effects of this utility model are as follows: 1. By coordinating the frame, shaft, first block, second block, groove, frame, rod, and first spring, the shaft drives the first block to rotate at the corresponding frame, enabling the switching between the second block with the groove, the second block at the other end, and the frame that moves through multiple rods. This allows the fixture to integrate multiple clamping functions without the need for frequent replacement of the entire fixture or complex bolt disassembly and positioning pin adjustment. While improving the fixture's versatility, it reduces module switching time to minimize the impact on processing cycle time. Furthermore, different clamping components can be adapted to different types of irregularly shaped parts such as shafts, plates, and irregular curved surfaces, better conforming to the part surface and helping to improve clamping stability. This addresses, to some extent, the problems of multiple fixtures, slow switching, and the need to improve stability in the processing of irregularly shaped parts, reducing equipment investment costs and operational complexity. 2. By coordinating the double-ended screw, sleeve, plate, and frame, the double-ended screw drives the two sleeves to move closer or further apart, thereby adjusting the distance between the two frames. This adjustment method eliminates the need to disassemble the frames or replace connecting parts; the distance can be controlled simply by rotating the double-ended screw. It is convenient to operate, reduces adjustment time, and avoids the impact of traditional disassembly-and-reassembly adjustments on processing cycle time. Furthermore, the screw drive's threaded transmission has stable self-locking properties, preventing distance deviation due to external forces after adjustment, thus helping to maintain the stability of the frames during subsequent operation. In addition, the screw drive offers high adjustment precision, allowing for adjustments to the frame distance according to actual needs, adapting to the clamping requirements of parts of different sizes, and improving the equipment's adaptability and flexibility.

[0015] 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.

[0016] Example 1, referring to Figures 1 to 5 A universal clamping fixture for irregularly shaped parts with quick-switchable clamping modules includes a plate 1, with a frame 2 at one end and the other end of the plate 1. Both frame 2 are rotatably connected to a shaft 3. Both shafts 3 are fixedly connected to a first block 4, the center of which is coaxially fixed with the shaft 3, ensuring that the shaft 3 can drive the first block 4 to rotate synchronously and smoothly. Both first blocks 4 are fixedly connected to a second block 5 at one end and the other end of each second block 4. Both second blocks 5 have a groove 6, which is V-shaped. The centerline of the groove 6 coincides with the centerline of the second block 5, ensuring a centering clamping effect for shaft-type parts. The remaining second blocks 5 are used to clamp and fix parts with flat surfaces. Both first blocks 4 are fixedly connected to a frame 7. Both frame 7 have multiple rods 8 that movably pass through them at equal intervals. Each rod 8 is fixedly connected to a corresponding frame 7 with a first spring 9, ensuring that the rods 8 can adaptively conform to the surface of the part under the elastic force of the first spring 9. Both plate 1 are fixedly connected to a sleeve 11 at one end and the other end of each plate 1.

[0017] In this embodiment, a double-ended screw 10 is rotatably connected to the plate 1. The shaft of the double-ended screw 10 is divided into two sections, each with an external thread in opposite directions. This allows the two sleeves 11 to move synchronously outward or inward to the two frames 2. The double-ended screw 10 is threadedly connected to the two sleeves 11. A handle 17 is fixedly connected to one end and the other end of the double-ended screw 10 for easy adjustment by the operator. Multiple bellows 19 are fitted onto the double-ended screw 10. The bellows 19 can extend and retract with the movement of the sleeves 11, effectively preventing dust, chips, and other impurities from entering the threaded mating surface, thus avoiding thread wear or jamming. One end of each bellows 19 is fixedly connected to the plate 1 or the sleeve 11. Insert rods 13 are movably inserted through both shafts 3. Both insert rods 13 are U-shaped. A second spring 14 is fitted to one end and the other end of each insert rod 13. The second spring 14 provides tension to keep the insert rod 13 inserted into the hole 12. Two springs 14 are fixedly connected at one end to the corresponding shaft 3 and the insertion rod 13 respectively. Both frames 2 are provided with multiple holes 12. The two insertion rods 13 are inserted into the corresponding holes 12 respectively. The straight section of the insertion rod 13 can be inserted into the corresponding hole 12 to realize the rotational positioning of the shaft 3 and the first block 4. One end of the plate 1 is fixedly connected to a slide rod 20. The slide rod 20 is slidably connected to the other two sleeves 11. The sleeves 11 can slide smoothly along the axis of the slide rod 20. Through the cooperation of the slide rod 20 and the double-headed screw 10, a guide-drive structure is formed to ensure the stability and straightness when adjusting the distance between the two frames 2. Multiple second blocks 5 are fixedly connected to rubber pads 16, which can flexibly fit the parts when in contact with the parts and avoid scratching the parts. Multiple rods 8 are fixedly connected to rubber blocks 15, and the rubber blocks 15 are hemispherical, which ensures the flexible fit of the rods 8 when in contact with the parts and avoids scratching the parts. The four corners of the plate 1 are fixedly connected to bases 18.

[0018] The working principle of this embodiment is as follows: In use, the shaft 3 drives the first block 4 to rotate at the corresponding frame 2, which allows for the switching between the second block 5 with the groove 6, the other end of the second block 5, and the frame 7 that movably passes through multiple rods 8. When fixation is required, the second spring 14 is used to contact the insertion rod 13 with the hole 12 at the corresponding frame 2, so that the clamp integrates multiple clamping functions. This eliminates the need for frequent replacement of the entire clamp set or complex bolt disassembly and positioning pin adjustment, improving versatility while reducing module switching time. Furthermore, different clamping components can be adapted to the shaft. For irregularly shaped parts such as plates, irregular curved surfaces, etc., the mechanism better fits the part surface to improve stability. At the same time, the handle 17 drives the double-ended screw 10 to drive the two sleeves 11 to move closer or further apart, which can realize the spacing adjustment of the two frame bodies 2. This method does not require disassembling the frame body 2 or replacing the connecting parts. The spacing change can be controlled simply by rotating the double-ended screw 10. The operation is convenient and reduces time consumption. The self-locking performance of the thread drive maintains the stability of the frame body 2. The high adjustment accuracy can also adapt to the clamping requirements of parts of different sizes, thus efficiently completing the clamping operation of irregularly shaped parts.

[0019] 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.
