Description

Technical Field

[0001] This utility model relates to the field of straightening equipment, and in particular to an adjustable transmission mechanism and a straightening machine. Background Technology

[0002] Currently, stainless steel welding plates are generally welded automatically by robots. Because these plates have high requirements for flatness and smoothness, the robots automatically identify and reject unqualified plates after extraction, resulting in a high scrap rate. Using straightening equipment to re-straighten unqualified stainless steel welding plates can reduce the scrap rate, improve material utilization, and lower costs.

[0003] Existing transmission mechanisms with rotating components generally cannot be adjusted after installation because they require a drive component to rotate. For example, in existing sheet metal straightening equipment, to adjust the distance between the upper and lower rollers (to meet the straightening needs of sheets of different thicknesses), there is no transmission relationship between the upper and lower rollers. To avoid affecting the transmission relationship between the upper and lower rollers when adjusting the distance, one of the upper and lower rollers rotates driven by the workpiece during straightening. Specifically, the drive component drives the lower roller to rotate, while the upper roller rotates through the sheet metal during straightening. This straightening method is significantly less effective than the simultaneous rotation of the upper and lower rollers. Furthermore, for small weld plates, the rotation of the upper roller is limited, affecting the straightening quality. The defect rate of straightened stainless steel weld plates remains relatively high. Utility Model Content

[0004] Therefore, the technical problem to be solved by this utility model is: how to adjust the position of the first rotating component while ensuring the transmission connection relationship of the first rotating component.

[0005] The above-mentioned technical problems are solved by the following technical solution: This utility model proposes an adjustable transmission mechanism, including: a first rotating member; a mounting assembly, the mounting assembly including a first upright plate disposed on the side of the first rotating member, and a second upright plate disposed on the side of the first upright plate away from the first rotating member; an adjustment assembly including an end seat movably disposed on the first upright plate, the first rotating member rotatably passing through the end seat, and a limiting member disposed between the end seat and the first upright plate; a transfer assembly including a deformation element, the first rotating member passing through the end seat and connected to the deformation element, and the end of the deformation element away from the first rotating member rotatably passing through the second upright plate; and a driving member, the end of the deformation element away from the first rotating member passing through the second upright plate and being drively connected to the driving member.

[0006] In a preferred embodiment of the adjustable transmission mechanism of this utility model: the mounting assembly further includes a base, and the first upright plate and the second upright plate are both fixed on the base.

[0007] In a preferred embodiment of the adjustable transmission mechanism of this utility model: both the first upright plate and the second upright plate are vertically fixed on the base.

[0008] In a preferred embodiment of the adjustable transmission mechanism of this utility model: the adjusting component further includes a notch disposed on the upper end of the first upright plate, the end seat is movably disposed in the notch, the limiting member is a threaded rod movably disposed on the upper part of the end seat, the portion of the limiting member above the end seat is threadedly connected to a horizontal plate, and the horizontal plate is fixed to the upper end of the first upright plate.

[0009] In a preferred embodiment of the adjustable transmission mechanism of this utility model, the width of the notch is the same as the width of the end seat.

[0010] In a preferred embodiment of the adjustable transmission mechanism of this utility model: the adapter assembly further includes a first connecting seat and a second connecting seat respectively disposed at both ends of the deformation element, the end of the first connecting seat away from the deformation element is connected to the first rotating member, and the end of the second connecting seat away from the deformation element is connected to the driving member for transmission.

[0011] In a preferred embodiment of the adjustable transmission mechanism of this utility model, the deformation element is a spring.

[0012] In a preferred embodiment of the adjustable transmission mechanism of this utility model, a support assembly is further provided between the end seat and the first upright plate, the support assembly including a movable part fixed to the lower end of the end seat.

[0013] In a preferred embodiment of the adjustable transmission mechanism of this utility model: the support assembly further includes an extension hole disposed at the lower end of the notch, the lower end of the movable member extends into the extension hole, a locking rod is threadedly connected to one side of the extension hole, and the inner end of the locking rod abuts against the movable rod.

[0014] This utility model also proposes a straightening machine, including the aforementioned adjustable transmission mechanism, and further including a second rotating member disposed below the first rotating member, the first rotating member including at least two first rotating rollers arranged side by side, the second rotating member including at least two second rotating rollers arranged side by side, the first rotating rollers and the second rotating rollers being staggered; a connecting assembly disposed between the first rotating member and the second rotating member, the connecting assembly including a driven gear disposed on the side of the connecting assembly away from the first rotating roller, and a driving gear disposed at the end of the second rotating roller, the driven gear meshing with its two adjacent driving gears; the driving member is a motor, the driving member being drivenly connected to one of the second rotating rollers.

This allows the straightening machine to adapt to the straightening of workpieces of different thicknesses while maintaining the common rotation of the upper and lower rollers, rather than only the lower roller rotating and the upper roller rotating through the workpiece. The straightening effect is significantly improved. Attached Figure Description

Furthermore, specific terms may be chosen by the applicant, and in such cases, their detailed meanings will be described in the detailed description of this invention. Therefore, the terminology used in this specification should not be construed as simple names, but rather based on the meaning of the terms and the overall description of this invention.

[0025] 1 was implemented

[0026] Reference Figure 1-5 This embodiment provides an adjustable transmission mechanism, including,

[0027] First rotating component 1;

[0028] Mounting component 2 includes a first upright plate 21 disposed on the side of the first rotating member 1, and a second upright plate 22 disposed on the side of the first upright plate 21 away from the first rotating member 1.

[0029] Adjustment component 3 includes an end seat 31 movably disposed on the first upright plate 21, a first rotating member 1 rotatably passing through the end seat 31, and a limiting member 32 provided between the end seat 31 and the first upright plate 21;

[0030] The adapter assembly 4 includes a deformation element 41. The first rotating member 1 passes through the end seat 31 and is connected to the deformation element 41. The end of the deformation element 41 away from the first rotating member 1 is rotatably mounted on the second vertical plate 22.

[0031] The end of the drive component 5 and the deformation element 41 away from the first rotating component 1 passes through the second vertical plate 22 and is connected to the drive component 5 for transmission.

[0032] The first rotating component 1 is specifically a roller, ball, or conical component, such as a pressure roller or a grinding head, which can rotate along its own axial direction. The first rotating component 1 is movably mounted on the first vertical plate 21 through an end seat 31. By adjusting the position of the end seat 31 on the first vertical plate 21, the position of the first rotating component 1 can be adjusted to adapt to the processing of different types of workpieces. At the same time, the first rotating component 1 is connected to the driving component 5 through a connecting assembly 4 with a deformation element 41. When adjusting the position of the first rotating component 1, the transmission relationship between the first rotating component 1 and the driving component 5 will not be affected.

[0033] The deformation element 41 is an elastic deformation element, such as a spring or a metal hose, preferably a spring.

[0034] Furthermore, refer to Figure 3 The mounting component 2 also includes a base 23, and the first upright plate 21 and the second upright plate 22 are both fixed on the base 23;

[0035] The base 23 is used to support the entire transmission mechanism. It is placed on the ground or a platform during use. The first upright plate 21 and the second upright plate 22 are both fixed on the base 23 for the installation and support of the first rotating part 1 and the adapter assembly 4. The first upright plate 21 and the second upright plate 22 are preferably fixed vertically on the base 23.

[0036] Furthermore, refer to Figure 1-5The adjustment component 3 also includes a notch 33 located at the upper end of the first upright plate 21, an end seat 31 movably located within the notch 33, a limiting member 32 being a threaded rod movably located at the upper part of the end seat 31, and a horizontal plate 34 threadedly connected to the portion of the limiting member 32 above the end seat, the horizontal plate 34 being fixed at the upper end of the first upright plate 21.

[0037] By changing the position of the end seat 31 at the depth of the notch 33, the position of the first rotating member 1 in the depth direction of the notch 33 is adjusted. Specifically, the lower end of the limiting member 32 is rotatably mounted on the end seat 31, and the position between the limiting member 32 and the end seat 31 is relatively fixed. For example, the lower end of the limiting member 32 adopts an inverted T-shaped structure without threads and is rotatably mounted on the end seat 31, so that the limiting member 32 can drive the end seat 31 to move in the depth direction of the notch 33. The horizontal plate 34 is fixed on the upper end of the first vertical plate 21, and the limiting member 32 and the horizontal plate 34 are threadedly connected. By rotating the limiting member 32, the limiting member 32 moves relative to the horizontal plate 34, thereby driving the end seat 31 to move in the depth direction of the notch 33 to adjust the position of the first rotating member 1. In order to ensure the working stability of the first rotating member 1, the width of the notch 33 is the same as the width of the end seat 31, so as to restrict the movement of the end seat 31 in the width direction of the notch 33 and avoid lateral swaying.

[0038] Furthermore, refer to Figure 1-4 The adapter assembly 4 also includes a first connecting seat 42 and a second connecting seat 43 respectively disposed at both ends of the deformation element 41. The end of the first connecting seat 42 away from the deformation element 41 is connected to the first rotating member 1, and the end of the second connecting seat 43 away from the deformation element 41 is connected to the driving member 5 for transmission.

[0039] The second upright plate 22, the first connecting seat 42, and the second connecting seat 43 are provided for the installation and support of the deformation element 41. Specifically, the second connecting seat 43 is rotatably installed on the second upright plate 22, and the first connecting seat 42 is connected to the first rotating member 1 in a transmission connection, so that the deformation element 41 is rotatably installed between the first rotating member 1 and the second upright plate 22.

[0040] Example 2

[0041] In this embodiment, refer to Figure 1-5 The adjustable transmission mechanism also includes a support assembly 6 disposed between the end seat 31 and the first upright plate 21. The support assembly 6 includes a movable part 61 fixed to the lower end of the end seat 31. The support assembly 6 also includes an extension hole 62 disposed at the lower end of the notch 33. The lower end of the movable part 61 extends into the extension hole 62. A locking rod 63 is threadedly connected to one side of the extension hole 62. The inner end of the locking rod 63 abuts against the movable rod.

[0042] The support assembly 6 includes a movable part 61, an extension hole 62, and a locking rod 63. The extension hole 62 is located at the bottom of the notch 33 on the first upright plate 21. The upper end of the movable part 61 is fixed to the end seat 31, and the lower end extends into the extension hole 62. The locking rod 63 is threaded to the first upright plate 21, and its inner end extends into the extension hole 62 and abuts against the movable part 61. When adjusting the position of the first rotating part 1, the locking rod 63 is rotated to release the abutment of the locking rod 63 against the movable part 61. Then, the position of the first rotating part 1 is adjusted, and the movable part 61 moves with the first rotating part 1. After adjustment, the locking rod 63 is rotated again so that the inner end of the locking rod 63 abuts against the movable part 61 again, thereby fixing the position of the movable part 61 and thus fixing the position of the end seat 31, further improving the stability of the first rotating part 1 when rotating.

[0043] Example 3

[0044] Reference Figure 6 A straightening machine includes an adjustable transmission mechanism, and further includes...

[0045] The second rotating member 7 is disposed at the lower part of the first rotating member 1. The first rotating member 1 includes at least two first rotating rollers 11 arranged side by side. Each first rotating roller 11 has a corresponding connecting component 4 on one side. The second rotating member 7 includes at least two second rotating rollers 71 arranged side by side. The first rotating rollers 11 and the second rotating rollers 71 are arranged alternately.

[0046] The connecting assembly 8 is disposed between the first rotating member 1 and the second rotating member 7. The connecting assembly 8 includes a driven gear 81 disposed on the side of the transfer assembly 4 away from the first rotating roller 11 and a driving gear 82 disposed at the end of the second rotating roller 71. The driven gear 81 and its two adjacent driving gears 82 mesh.

[0047] The driving component 5 is a motor, and the driving component 5 is connected to one of the second rotating rollers 71 in a transmission connection.

[0048] The first rotating roller 11 and the second rotating roller 71 are connected by a connecting assembly 8, allowing them to rotate together. During straightening, both the first rotating roller 11 and the second rotating roller 71 are actively rotating on the plate to be straightened, rather than one rotating actively while the other is driven to rotate by the plate to be straightened. This improves the smoothness of the plate's movement and the straightening effect. The driving component 5 is connected to one of the second rotating rollers 71, driving the first rotating roller 11 and the second rotating roller 71 to rotate. The specific installation method of the connecting assembly 8 and the driving component 5 is as follows: a third upright plate 24 is also provided on the base 23. The driving gear 82 and the driven gear 81 are rotatably disposed between the second upright plate 22 and the third upright plate 24. The driving component 5 is fixed on the base 23, and the output shaft of the driving component 5 is connected to one of the driving gears 82.

[0049] Since the deformation range of the deformation element 41 is limited, this straightening machine is more suitable for straightening small plates with small thickness differences between different models, such as the straightening of stainless steel welding plates.

[0050] By adjusting the setting of component 3, the distance between the upper and lower rollers of the straightening machine can be adjusted, thereby adapting to the straightening of different types of workpieces. By setting the adapter component 4 with deformation element 41, when adjusting the distance between the upper and lower rollers, the deformation of the deformation element 41 is used to compensate for the change in position between the upper and lower rollers, thereby maintaining the transmission connection between the upper and lower rollers. This allows the straightening machine to adapt to the straightening of workpieces of different thicknesses while maintaining the common rotation of the upper and lower rollers, rather than only the lower roller rotating and the upper roller rotating through the workpiece. The straightening effect is significantly improved.

[0051] In the first half of 2023, the medium plate finished product workshop scrapped a total of 8,256 welding plates. After the scrapped welding plates were straightened and recycled using this straightening machine in June 2023, only 360 welding plates were scrapped in the second half of 2023. The number of scrapped welding plates was reduced by 7,896 in half a year, and the scrap rate of welding plates was reduced by as much as 95.6%.

[0052] Finally, it should be noted that the methods and devices described in detail above are merely embodiments, and those skilled in the art can modify these embodiments in different ways, as long as they do not depart from the scope of this utility model.
