Description

Technical Field

[0001] The utility model relates to the technical field of building plates, in particular to an auxiliary device for locking seams of roof metal plates. Background Art

[0002] Metal sheets for roofing refer to color-coated steel sheets, aluminum-magnesium-manganese sheets, aluminum-zinc-coated sheets and other metal sheets used for roofing. The metal sheet lock seam machine is an automated device that can quickly and reliably bite the male and female ends of two metal sheets together. After the metal roof is installed and fixed, the lock seam machine needs to be used to bite the male and female ends together to make the metal roof airtight and rainproof.

[0003] In the related technical solutions, when installing the metal plate lock seam machine, due to the influence of installation skills, production and processing, metal properties, etc. during the installation of the plate, it is easy to cause the installation width to be inconsistent with the theoretical value, resulting in deviations in the overlap size and angle of the male and female joints of the metal plate. The deviation caused by the above installation has a great impact on the lock seam quality of the lock seam machine. Utility Model Content

[0004] The utility model provides an auxiliary device for locking seams of roof metal plates, which can at least solve one of the above technical problems.

[0005] To solve the above technical problems, one or more embodiments of the utility model provide an auxiliary device for locking seams of roofing metal plates, comprising a support frame, an eccentric shaft, an upper roller and a lower roller, the support frame having two support plates arranged opposite to each other, and a rotation space is formed between the two support plates; a downward extension plate is connected to the lower part of one of the support plates, and the extension plate has an extension portion located below the rotation space; the eccentric shaft is arranged in the rotation space, and the two ends of the eccentric shaft are respectively rotatably connected to the two support plates, and a locking member is detachably installed at the support plate to lock the rotation between the eccentric shaft and the support plate; the upper roller is rotatably sleeved on the outside of the eccentric shaft; the lower roller is rotatably installed on the extension portion; the rotation axes of the eccentric shaft, the upper roller and the lower roller are parallel to each other.

[0006] The beneficial effects of one or more of the above technical solutions are:

[0007] (1) In this scheme, the auxiliary device includes a support frame, an eccentric shaft is installed on the support frame, an upper roller is installed on the eccentric shaft, and a lower roller is installed on the extension plate at the bottom of the support frame; and a locking member is detachably installed on the support plate, and the locking member can lock the eccentric shaft. This arrangement makes it easy to adjust the distance between the upper roller and the lower roller by rotating and locking the eccentric shaft, and then to increase the distance between the upper roller and the lower roller so that the male and female ports of the metal panels overlap each other and are placed between the upper roller and the lower roller; and this arrangement also makes it easy to reduce the distance between the upper roller and the lower roller so that the overlapping position and angle of the male and female ports of the metal panels can be adjusted by using the roller stop.

[0008] (2) In this solution, the rotatable upper and lower rollers are used to adjust the overlapping size and angle of the overlapping male and female ends. This arrangement makes it easy to continuously adjust the area to be sealed along the extension direction of the male end by rotating the upper and lower rollers, so as to cooperate with the locking machine to achieve continuous locking of the metal roof panel.

[0020] See also Figure 2 The two adjacent metal panels have a first flange 901 and a second flange 902, respectively. The upper end of the first flange 901 forms a female opening, and the upper end of the second flange 902 forms a male opening. The male opening is embedded in the female opening so that the two overlap and contact. Figure 2 The left-right direction is defined as the width direction of the metal panel. At this time, the male and female ports may not be aligned in the width direction, resulting in size errors and angle errors.

[0021] See also Figure 1-Figure 6 An embodiment of the utility model provides an auxiliary device for locking seams of roofing metal plates, including a support frame, an eccentric shaft 12, an upper roller 501 and a lower roller 8, the support frame has two support plates arranged opposite to each other, and a rotation space is formed between the two support plates; a downward extension plate 4 is connected to the lower part of one of the support plates, and the extension plate 4 has an extension portion located below the rotation space; the eccentric shaft 12 is arranged in the rotation space, and the two ends of the eccentric shaft 12 are respectively rotatably connected to the two support plates, and a locking member is detachably installed at the support plate to lock the rotation between the eccentric shaft 12 and the support plate; the upper roller 501 is rotatably sleeved on the outside of the eccentric shaft 12; the lower roller 8 is rotatably installed on the extension portion; the rotation axes of the eccentric shaft 12, the upper roller 501 and the lower roller 8 are parallel to each other.

[0022] In this embodiment, the support frame is in a door shape, and the upper ends of the two support plates are fixed by a connecting plate 13. Specifically, the two support plates are parallel to each other, and the connecting plate 13 is perpendicular to the support plates. Here, the support plate and the connecting plate 13 can be fixed by bolts. In other structural settings, the two can also be fixed by welding or other methods, as long as the strength requirements can be met.

[0023] In this embodiment, see Figure 1 and Figure 5 In this embodiment, the support plate includes a first plate 2 and a second plate 3 , the lower end of the second plate 3 is lower than the lower end of the first plate 2 , and the extension plate 4 is installed on the lower end of the second plate 3 .

[0024] Specifically, when the support plate of the support frame is in a vertical state, the second plate 3 is vertically convex to the first plate 2. A shaping space is defined between the outer peripheral surface of the first roller and the outer peripheral surface of the second roller. At any time when the eccentric shaft 12 rotates to adjust the distance between the first roller and the second roller, the portion of the first plate 2 that is vertically higher than the second plate 3 is equivalent to forming a notch. When in use, the notch is exposed from one side of the first plate 2, which is convenient for inserting the male and female ports into the shaping space, or taking the male and female ports out of the shaping space.

[0025] In this embodiment, the extension plate 4 includes a vertical portion and an extension portion, the vertical portion is connected to the support plate and extends downward along the support plate, the extension portion is L-shaped, and the extension portion includes a transverse section connected to the vertical portion and a vertical section extending upward from the transverse section.

[0026] Specifically, this arrangement facilitates embedding the vertical end of the extension portion into the male opening and the female opening to support the second roller.

[0027] In this embodiment, the locking member includes a positioning pin, and one of the end faces of the eccentric shaft 12 has a positioning hole, the axis of the positioning hole is parallel to the rotation axis of the eccentric shaft 12; the positioning pin can pass through the through hole of the support plate and the positioning hole in sequence to lock the eccentric shaft 12.

[0028] In this embodiment, two positioning holes are provided on one side of a single positioning pin. Correspondingly, two through holes are provided on the support plate near each positioning hole. In some other embodiments, only a single positioning hole may be provided at a single positioning pin, and in this case, only one through hole is provided at the support plate.

[0029] In this embodiment, a locking seat 6 is provided on the outer side of the first plate 2 away from the rotation space. The locking seat 6 has a mounting hole 7 that penetrates the first plate 2 and is coaxial with the through hole.

[0030] Specifically, the locking seat 6 is a square seat, and the locking seat 6 can be fixed to the first plate 2 by welding or gluing.

[0031] In this embodiment, there are multiple eccentric shafts 12, and the central axes of the multiple eccentric shafts 12 are in the same first plane; there are multiple lower rollers 8, and the central axes of the multiple lower rollers 8 are in the second plane, and the first plane and the second plane are parallel.

[0032] More specifically, the outer diameter of the upper roller 501 is greater than the outer diameter of the lower roller 8. The outer peripheral surface of the upper roller 501 has an annular groove, and the width of the annular groove is equal to the width of the female port to be crimped.

[0033] In this embodiment, a bearing 502 is sleeved between the eccentric shaft 12 and the upper roller 501. The bearing 502 is used to reduce the friction force when the upper roller 501 rotates around the eccentric shaft 12.

[0034] In this embodiment, the top of the support frame has a handle 1. The user can easily control the second roller to be embedded in the structure where the male and female ports are buckled by the handle 1. Specifically, the handle 1 can be fixed to the connecting plate 13 by welding or bolts.

[0035] Working principle: When using this device, the personnel will tilt the device so that the lower roller 8 enters the internal space after the male and female ports of the metal plate 9 are buckled together. At this time, the device is rotated to a vertical state, and the eccentric shaft 12 at the upper roller 501 is rotated so that the upper roller 501 and the lower roller 8 clamp the plate parts at the male and female ports of the metal plate 9, and bolts are passed through the mounting holes 7, through holes and positioning holes to fix the eccentric shaft 12 on the support plate. At this time, the preparation of the auxiliary device 10 is completed.

[0036] According to the lock-stitching process, the lock-stitching machine 11 is prepared and placed behind the auxiliary device 10. The lock-stitching machine 11 is started to push against the auxiliary device 10, and the auxiliary device 10 continuously corrects the metal plate 9 to the correct position. Since the auxiliary device 10 is very close to the lock-stitching machine 11, the metal plate 9 continuously corrected by the auxiliary device 10 is fed into the roller of the lock-stitching machine 11, so that the lock-stitching shape of the metal plate 9 meets the lock-stitching requirements and the lock-stitching quality is guaranteed.

[0037] The above-mentioned specific implementation manner cannot be used as a limitation on the protection scope of the present utility model. For those skilled in the art, any replacement, improvement or change made to the implementation manner of the present utility model falls within the protection scope of the present utility model.
