[0031] like Figure 1As shown, the embodiment of the present invention provides a fixture for elbow processing, including a base plate 1, a "Y"-shaped side plate 2 is fixedly connected to one side of the top of the base plate 1, a transmission cavity is opened on each oblique side of the side plate 2, a transmission screw 3 is rotatably connected to the inside of the transmission cavity, one end of the transmission screw 3 is fixedly connected to the adjusting disk, the external thread of the transmission screw 3 is connected to the transmission block 4, the front of the transmission block 4 is provided with a connecting seat 5, the front of the connecting seat 5 is fixedly connected to a fixing member 6, the top of the base plate 1 is fixedly connected to a connecting member 101, the connecting member 101 is located below the center of the side plate 2, a connecting groove is opened inside the top of the connecting member 101, an elbow is clamped inside the connecting groove, and a circular limiting cavity 601 is opened inside the fixing member 6. A plurality of clamping components are provided on the inner wall of the limiting cavity 601, and each clamping component includes two "C"-shaped reset springs 602 connected to the inside of the limiting cavity 601, and an arc-shaped clamping piece 603 is provided on the surface of the reset spring 602 facing the center of the limiting cavity 601, and a plurality of semicircular limiting protrusions 604 are provided on the surface of the arc-shaped clamping piece 603, and a deformation cavity 605 is opened inside each limiting protrusion 604. When the elbow needs to be clamped, the transmission screw 3 is first driven to rotate in the transmission cavity by rotating the adjusting disk. The rotation of the transmission screw 3 drives the transmission block 4 to move along its thread direction, thereby pushing the connecting seat 5 and the fixing part 6 toward the elbow. When the limiting cavity 601 inside the fixing part 6 contacts the outer surface of the elbow, the two " The C"-shaped reset spring piece 602 begins to be stressed and deformed. The elastic deformation of the reset spring piece 602 causes the arc-shaped clamping piece 603 to move toward the center of the elbow, thereby achieving preliminary clamping of the elbow. The multiple semicircular limiting protrusions 604 on the surface of the arc-shaped clamping piece 603 are in close contact with the outer surface of the elbow, which increases the stability and firmness of the clamping. The deformation cavity 605 design inside the limiting protrusion 604 allows the limiting protrusion 604 to undergo a certain deformation when stressed, thereby better adapting to the shape and size of the elbow, improving the adaptability and flexibility of the fixture. After the clamping is stable, the elbow can be processed by other processing equipment, such as welding, cutting, etc. The design of the fixture ensures the stability and accuracy of the elbow during processing. The clamp is flexible and adaptable to different sizes and shapes of elbows, and its versatility and applicability are improved. The limiting protrusion 604 on the surface of the arc-shaped clamping piece 603 is in close contact with the outer surface of the elbow, which increases the friction and stability of the clamping and avoids the shaking or falling off of the elbow during processing. The clamp can be easily clamped and released by rotating the adjusting dial without complicated operation procedures or additional tools, which improves work efficiency. The deformation cavity 605 design inside the limiting protrusion 604 allows the clamp to undergo a certain deformation during the clamping process, thereby avoiding damage or scratches to the elbow surface caused by over-tight clamping.

[0032] In this embodiment, if Figures 1 to 5As shown, a circular fixed disk 401 is fixedly connected to the front of the transmission block 4, and a number of obliquely arranged arc-shaped interference members 402 are fixedly connected to the edge of the fixed disk 401 at equal intervals in an annular manner. A cavity is provided on the fitting surface of the connecting seat 5 and the fixed disk 401, and an "L"-shaped limiting member 501 is fixedly connected to the inner wall of the cavity. The contact surface between the limiting member 501 and the interference member 402 is arc-shaped. There are five limiting members 501, and each limiting member 501 is located between two arc-shaped interference members 402. The interior of the fixed disk 401 is rotatably connected to a rotating disk 403, and a docking hole 404 is provided inside the rotating disk 403. The interior of the cavity of the limiting member 501 is fixedly connected to a docking member 502, and a "C"-shaped guide portion is provided at the bottom of the docking member 502. The connecting pieces 502 are distributed in a petal shape, and the outside of the docking piece 502 is adapted to the inside of the docking hole 404. When the fixing piece 6 needs to be replaced to adapt to elbows of different sizes, the user can directly pull the connecting seat 5 outward. This action causes the guide part of the docking piece 502 to be stressed. Since the guide part is designed to be "C"-shaped, it has a certain elastic deformation ability. As the connecting seat 5 is pulled, the guide part of the docking piece 502 will avoid inward and deform, thereby allowing the connecting seat 5 to be separated from the transmission block 4. At this time, the user can easily remove the original fixing piece 6 and the connecting seat 5 from the transmission block 4. After removing the original fixing piece 6, the user can select a new fixing piece 6 that is adapted to the current elbow size for installation, and then install the new fixing piece. The connecting seat 5 of 6 is aligned with the fixing plate 401 on the transmission block 4 and is gently pushed inward. As the connecting seat 5 is pushed in, the guiding portion of the docking piece 502 will gradually return to its original shape and guide the docking hole 404 to adapt to the outer portion of the docking piece 502, thereby achieving a stable connection between the connecting seat 5 and the transmission block 4. After the fixing piece 6 is installed, the user can adjust its position or angle by rotating the fixing piece 6. This rotation action will drive the connecting seat 5 to rotate together, and then the limiting piece 501 will rotate accordingly. Since the shape of the limiting piece 501 is designed to be "L"-shaped and its number matches the number of arc-shaped interference pieces 402 (each limiting piece 501 is located between two arc-shaped interference pieces 402), when the limiting piece 501 rotates, it The resisting piece 402 on one side is squeezed until the limiting piece 501 moves between the other two resisting pieces 402, thereby completing self-locking, and thus being able to adapt to elbows of different angles. By designing the "C"-shaped guide portion of the docking piece 502 and the elastic deformation ability of the arc-shaped resisting piece 402, the replacement process of the fixing piece 6 is made faster and more convenient. The user can easily complete the replacement of the fixing piece 6 without using additional tools or performing complicated operations. The design of the clamp fully considers the clamping requirements of elbows of different sizes. By replacing fixing pieces 6 of different sizes and adjusting their positions or angles, the clamp can adapt to the processing requirements of elbows of various shapes and sizes. The coordinated use of the arc-shaped resisting piece 402 and the limiting piece 501 increases the stability of the clamp when clamping the elbow.Even when subjected to large impacts or vibrations during processing, the fixture can maintain a stable clamping state, ensuring processing quality and safety. The entire fixture operation process is simple and clear. Users only need to perform simple actions such as rotation, pushing and pulling to complete the fixture fixation, replacement and adjustment work. This not only reduces the difficulty and time cost of operation, but also improves work efficiency and processing accuracy.

[0033] The working principle provided by the present invention is that when the fixing part 6 needs to be replaced to adapt to elbows of different sizes, the user can directly pull the connecting seat 5 outward. This action causes the guide part of the docking part 502 to be subjected to force. Since the guide part is designed to be "C"-shaped, it has a certain elastic deformation ability. As the connecting seat 5 is pulled, the guide part of the docking part 502 will avoid inward and deform, thereby allowing the connecting seat 5 to be separated from the transmission block 4. At this time, the user can easily remove the original fixing part 6 and the connecting seat 5 from the transmission block 4. After removing the original fixing part 6, the user can select a new fixing part 6 that is adapted to the current elbow size for installation, align the connecting seat 5 of the new fixing part 6 with the fixing disk 401 on the transmission block 4, and Push it inwards gently. As the connecting seat 5 is pushed in, the guide portion of the docking piece 502 will gradually return to its original shape and guide the docking hole 404 to adapt to the outside of the docking piece 502, thereby achieving a stable connection between the connecting seat 5 and the transmission block 4. After the fixing piece 6 is installed, the user can adjust its position or angle by rotating the fixing piece 6. This rotation action will drive the connecting seat 5 to rotate together, and then the limiting piece 501 will also rotate. Since the shape of the limiting piece 501 is designed to be "L"-shaped and its number matches the number of arc-shaped interference pieces 402 (each limiting piece 501 is located between two arc-shaped interference pieces 402), when the limiting piece 501 rotates, it will squeeze the interference piece 402 on one side until the limiting piece 501 moves to The other two resisting members 402 complete self-locking, which can adapt to elbows of different angles. When the elbow needs to be clamped, first drive the transmission screw 3 to rotate in the transmission cavity by rotating the adjusting disk. The rotation of the transmission screw 3 drives the transmission block 4 to move along its thread direction, thereby pushing the connecting seat 5 and the fixing member 6 toward the elbow. When the limiting cavity 601 inside the fixing member 6 contacts the outer surface of the elbow, the two "C"-shaped reset springs 602 begin to be stressed and deformed. The elastic deformation of the reset spring 602 causes the arc-shaped clamping piece 603 to move toward the center direction of the elbow, thereby achieving preliminary clamping of the elbow. The multiple semicircular limiting protrusions 604 on the surface of the arc-shaped clamping piece 603 are in close contact with the outer surface of the elbow, which increases the clamping effect. Stability and firmness. The deformation cavity 605 design inside the limiting protrusion 604 allows the limiting protrusion 604 to undergo a certain deformation when subjected to force, thereby better adapting to the shape and size of the elbow, improving the adaptability and flexibility of the clamp. After the clamp is stable, the elbow can be processed by other processing equipment, such as welding, cutting, etc. The design of the clamp ensures the stability and accuracy of the elbow during the processing, improves the processing efficiency and quality, and through the elastic clamping effect of the reset spring piece 602 and the arc-shaped clamping piece 603, the clamp can adapt to elbows of different sizes and shapes, improving the versatility and applicability of the clamp. The limiting protrusion 604 on the surface of the arc-shaped clamping piece 603 is in close contact with the outer surface of the elbow, which increases the friction and stability of the clamping.This prevents the elbow from shaking or falling off during processing. The clamp can be easily clamped and released by rotating the adjustment dial, without the need for complicated operation procedures or additional tools, which improves work efficiency. The deformation cavity 605 design inside the limiting protrusion 604 allows the clamp to deform to a certain extent during the clamping process, thereby avoiding damage or scratches on the elbow surface caused by over-tightening.

To provide a thorough understanding of this invention, specific details are described in detail in the following preferred embodiments of this invention, but those skilled in the art will be able to fully understand this invention without these detailed descriptions. Furthermore, to avoid unnecessary confusion regarding the essence of this invention, well-known methods, processes, procedures, components, and circuits are not described in detail.
