[0003] After searching, the Chinese patent announcement number: CN221495748U discloses a clamp for mechanical manufacturing. The manufacturing clamp can tightly contact the inner wall of the tubular component through the fixed component through the set fixing component, so that the tubular component can be stably clamped on one side of the vertical plate, thereby effectively solving the problem that the existing device usually clamps the outer wall of the tubular component, but is blocked by the clamping component, resulting in the inability to grind or cut the clamped part of the tubular component, and requires subsequent manual grinding and cutting of the clamped part.

[0004] During use, the multi-stage rod and the sliding rod of the aforementioned manufacturing fixture are in a state of constant compression, which increases friction between them and causes severe wear. This wear affects the geometry and clearance of the components, thereby reducing the accuracy of the fixture. Therefore, a manufacturing fixture is proposed to address this issue.

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0031] Reference Figure 1 The utility model provides an embodiment: a manufacturing fixture, including a base 1, a straight plate 2 is fixedly connected to the surface of the base 1, a plurality of array-distributed reinforcement plates 21 are fixedly connected between the base 1 and the straight plate 2, the plurality of reinforcement plates 21 are used to reinforce the straight plate 2, and a clamping assembly 3 is provided on the side wall of the straight plate 2, and the clamping assembly 3 is used to support the inner wall of the tubular component, thereby achieving the effect of clamping and fixing.

[0032] Reference Figure 1 - Figure 2The clamping assembly 3 includes a turntable 31, which is fixedly connected to the side wall of the straight plate 2. A fixed shaft 32 is fixedly connected to the side wall of the turntable 31. Two sets of symmetrically arranged circular rings 33 are slidably connected to the interior of the fixed shaft 32. The interior of the fixed shaft 32 is hollow, allowing the two sets of circular rings 33 to slide along its inner wall. The side wall of the fixed shaft 32 is provided with a sliding groove 34, and two sets of symmetrically arranged mounting blocks 35 are slidably connected to the interior of the sliding groove 34. The mounting blocks 35 are fixedly connected to the side wall of the circular rings 33. The sliding groove 34 connects the internal and external spaces of the fixed shaft 32, providing a track for the mounting blocks 35 to move, and they move synchronously with the mounting blocks 35. A support plate 36 is hinged to the side wall of the mounting block 35, and an arc-shaped plate 37 is hinged to the end of the support plate 36. By the two groups of mounting seats 35 moving toward each other or away from each other, the mounting seats 35 drive one end of the support plate 36 to move accordingly, thereby adjusting the inclination angle of the support plate 36, so that the arc-shaped plate 37 is expanded outward or gathered inward, and the arc-shaped plate 37 is fitted with the inner wall of the tubular component, thereby achieving the effect of fixing it to the tubular component.

[0033] Reference Figure 2 A bidirectional threaded rod 38 is threadedly connected between the two sets of circular rings 33. The bidirectional threaded rod 38 extends through and is rotatably connected to the end of the fixed shaft 32. A motor 1 39 is fixedly connected to the end of the fixed shaft 32. One end of the bidirectional threaded rod 38 is rotatably connected to the inner wall of the fixed shaft 32, and the other end is fixedly connected to the output shaft of motor 1 39. Motor 1 39 rotates the bidirectional threaded rod 38 via its output shaft, thereby controlling the movement of the circular rings 33. A motor 2 310 is fixedly connected to the side wall of the straight plate 2. The output shaft of motor 2 310 extends through and is rotatably connected to the side wall of the straight plate 2. Motor 2 310 is fixedly connected to the side wall of the turntable 31. Motor 2 310 is used to drive the turntable 31 to rotate, thereby rotating the tubular component.

[0034] Reference Figure 1 、 Figure 3 The surface of the base 1 is provided with a support assembly 4, which includes an electric telescopic rod 41. One end of the electric telescopic rod 41 is fixedly connected to the surface of the base 1, and the other end of the electric telescopic rod 41 is fixedly connected to a pad 42. The electric telescopic rod 41 is used to adjust the height of the pad 42 so that the pad 42 is close to the outer wall of the tubular component to accommodate tubular components of different diameters. The surface of the pad 42 is fixedly connected to a V-shaped plate 43. The V-shaped plate 43 can effectively fit the outer walls of tubular components of different diameters, improving the stability of the tubular components during rotation. The side walls of the V-shaped plate 43 are fixedly connected to two sets of symmetrically arranged protrusions 44, and a laminating roller 45 is rotatably connected between the two sets of protrusions 44. The protrusions 44 are used to fix the laminating roller 45, which reduces the friction between the laminating roller 45 and the V-shaped plate 43, facilitating the rotation of the tubular component.

[0035] Working Principle: When motor 1 39 is activated, the bidirectional threaded rod 38 rotates, pushing the two sets of rings 33 to move relative to each other along the inner wall of the fixed shaft 32. This movement drives the mounting base 35 to slide along the slide 34, thereby changing the inclination angle of the support plate 36. The end of the support plate 36 is connected to the curved plate 37 via a hinge, so that the curved plate 37 can adjust its fit with the inner wall of the tubular component according to the inclination of the support plate 36. When the curved plate 37 is tightly fitted with the inner wall of the tubular component, the tubular component can be stably clamped. At the same time, the activation of motor 2 310 causes the turntable 31 to rotate, thereby driving the tubular component to rotate.

[0036] The telescopic function of the electric telescopic rod 41 allows the backing plate 42 to adapt to tubular components of varying diameters, ensuring that the V-shaped plate 43 effectively conforms to the outer wall of the tubular component. The V-shaped plate 43 can adapt to tubular components of varying sizes, ensuring its stability during rotation. The conforming roller 45 further reduces friction with the V-shaped plate 43, ensuring smoother rotation of the tubular component and minimizing the risk of surface damage.

[0037] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
