DETAILED DESCRIPTION

[0031] The technical solution of the present invention is described in detail below in conjunction with the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0032] This embodiment provides an assembly, welding and correction machine with a welding slag cleaning function, including a self-driven welding slag cleaning device, a conveying device, an assembly mechanism, a welding device and a correction device.

[0033] The assembly mechanism, welding device, self-driven slag cleaning device and correction device are arranged in sequence along the conveying direction of the conveying device. The web and wing plates of the H steel first pass through the assembly mechanism to achieve positioning and form a predetermined structure, then arrive at the welding device to complete the welding of the root weld of the web, then pass through the self-driven slag cleaning device to complete the cleaning, and finally arrive at the correction device to correct the shape and size of the steel parts to ensure the accuracy and quality of the product.

[0034] Furthermore, if Figure 1 , Figure 2 and Figure 3 The self-driven welding slag cleaning device includes a base body, a driving wheel 7 and a cleaning disc 8.

[0035] The base comprises a column 1, a lifting plate 3, a guide plate 5 and a rotating plate 6. The column 1 is fixedly arranged, the lifting plate 3 is mounted on the column 1 and can be lifted and lowered relative to the column 1, the guide plate 5 is horizontally slidably connected to the lifting plate 3, the rotating plate 6 is horizontally rotatably connected to the lifting plate 3, and the driving wheel 7 and the cleaning disc 8 are mounted on the rotating plate 6.

[0036] The driving wheel 7 is used to contact with the welded web 9 and rotate under the action of the web 9. The cleaning disc 8 is located at the weld seam between the welded web 9 and the wing plate 10. The driving wheel 7 is connected to the cleaning disc 8 through an intermediate transmission mechanism. Figure 2 and Figure 3The intermediate transmission mechanism includes a driving gear 11 connected to the driving wheel 7 and a driven gear 12 connected to the cleaning disc 8. The number of teeth of the driving gear 11 is greater than that of the driven gear 12, so that the cleaning disc 8 rotates faster and improves the cleaning effect. In this embodiment, the ratio of the number of teeth of the two is 2:1. The intermediate transmission mechanism can also be a structure such as a transmission belt.

[0037] Specifically, Figure 5 The column 1 is provided with an external threaded portion, the through hole at the outer end of the lifting plate 3 is sleeved on the external threaded portion, a protrusion is provided on the inner side of the through hole, and a groove is provided on the external threaded portion, and the two realize vertical sliding fit. Figure 4 The lifting plate 3 is fixed on the column 1 through two sets of upper and lower fastening nuts 2 that cooperate with the external threaded part.

[0038] like Figure 2 and Figure 3 The guide plates 5 are divided into two groups, one above the other, and are located at the upper and lower sides of the inner end of the lifting plate 3 and the outer end of the rotating plate 6. In this embodiment, a linear groove 502 is provided on the guide plates 5, and the two groups of guide plates 5 and the lifting plate 3 are connected in a horizontal sliding manner by a first fastener that passes through the linear groove 502 and the lifting plate 3. The first fastener is only used for sliding connection and is not fastened during normal operation.

[0039] Furthermore, if Figure 4 , the lifting plate 3 is provided with a first vertical plate 301, the guide plate 5 is provided with a second vertical plate 503, a distance adjustment mechanism 4 is provided between the first vertical plate 301 and the second vertical plate 503, and the distance adjustment mechanism 4 is provided with an elastic buffer device. Specifically, the distance adjustment mechanism 4 includes a regulator composed of a first screw rod 401 and a sleeve 402 that are fixedly connected, and also includes a clamping rod composed of a second screw rod 405 and an optical axis 404 that are fixedly connected. The first screw rod 401 cooperates with the threaded hole on the second vertical plate 503, the second screw rod 405 cooperates with the threaded hole on the first vertical plate 301, the optical axis 404 slidably cooperates with the inner hole of the sleeve 402, and the spring 403 as the elastic buffer device is located in the inner hole of the sleeve 402 and the outer end is in contact with the optical axis 404.

[0040] As an optional implementation, the distance adjustment between the guide plate 5 and the lifting plate 3 can also be achieved manually or in other ways.

[0041] Furthermore, if Figure 2 and Figure 3 The guide plate 5 is also provided with an arc groove 501, the center of which coincides with the axis of the horizontal rotation connection between the guide plate 5 and the rotating plate 6. The guide plate 5 and the rotating plate 6 are also connected by a second fastener passing through the arc groove 501.

[0042] Furthermore, if Figure 2 The rotation axis of the driving wheel 7, the rotation axis of the cleaning disc 8, and the axis of the horizontal rotation connection between the guide plate 5 and the rotating plate 6 are located in the same vertical plane, the angle between the vertical plane and the normal plane of the conveying direction of the web 9 is 15 degrees, and the rotation axis of the driving wheel 7 is located on the side of the guide plate 5 close to the conveying starting end of the web 9.

[0043] Furthermore, the self-driven welding slag cleaning device is composed of two left and right groups that are relatively arranged, and are respectively arranged on both sides of the welded web 9.

[0044] In order to realize the centralized recovery of welding slag, a collection box is also provided below the cleaning plate 8 .

[0045] Before work, first loosen the fastening nut 2 to adjust the height of the lifting plate 3, tighten the fastening nut 2 to fix the height of the lifting plate 3, then loosen the second fastener to adjust the angle of the rotating plate 6, and after tightening the second fastener, rotate the handwheel at the end of the first screw 401 (the first fastener remains loosened) to adjust the horizontal position of the guide plate 5 relative to the lifting plate 3. When the driving wheel 7 contacts the web 9, rotate the handwheel at the end of the second screw 405 to change the compression of the spring, and accurately adjust the clamping force between the driving wheel 7 and the web 9. The preparation work is now completed.

[0046] When the web 9 and the wing plate 10 are transported forward and welded, the driving wheel 7 will rotate under the friction of the web 9, and then drive the cleaning disc 8 to rotate through the driving gear 11 and the driven gear 12, thereby realizing the automatic cleaning function of the welding slag.

[0047] When the end of the web 9 hits the driving wheel 7, Figure 2 As shown, the rotating plates 6 on the left and right sides have a tendency to rotate clockwise / counterclockwise along the arc groove 501 respectively. This tendency will make the driving wheels 7 on both sides closer to the belly plate 9, thereby avoiding the driving wheels 7 from being separated from the belly plate 9 due to collision, resulting in failure of the cleaning function.

[0048] It should be noted that it is obvious to those skilled in the art that the present invention is not limited to the details of the above exemplary embodiments, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. The scope of the present invention is defined by the claims rather than the above description.
