Description

Technical Field

[0001] The utility model relates to the technical field of steel structure manufacturing, in particular to a permanent magnetic liner positioner. Background Art

[0002] In the welding process of steel box beams and other steel structures, due to limited space, a single-sided welding and double-sided forming welding process is usually adopted, that is, welding is performed on one side of the parent material, and the cladding metal flows into the other side of the parent material through the gap between the parent materials to form a double-sided weld. Therefore, the key point to achieve single-sided welding and double-sided forming is to ensure the gap between the parent materials. Figure 2 In the welding structure shown, in order to achieve a stable connection between the web and the bottom plate through the backing plate, it is necessary to position the backing plate through the web and ensure that there is a 2-3mm gap between the backing plate and the web. The traditional method is to insert a gasket between the backing plate and the web for positioning. However, since there is a gap between the web and the bottom plate, it is not easy to place the gasket and ensure the stability of the backing plate, resulting in unstable control of the gap between the backing plate and the web, and low gap accuracy, which affects the subsequent welding quality. Utility Model Content

[0003] In order to overcome the above-mentioned deficiencies in the existing welding process, the technical problem to be solved by the utility model is to provide a permanent magnetic liner positioner which can well control the welding gap of the parent material.

[0004] The technical solution adopted by the utility model to solve its technical problems is:

[0005] A permanent magnetic pad positioner comprises a handle, a connecting rod and an L-shaped support plate which are connected in sequence. The vertical section of the L-shaped support plate is connected to the connecting rod on the side facing away from the horizontal section. A groove is provided on the horizontal section of the L-shaped support plate on the side facing the vertical section. A permanent magnetic sheet is fixedly arranged in the groove. The distance from the top of the permanent magnetic sheet to the bottom of the L-shaped support plate is the weld gap required between two welding base materials.

[0006] Furthermore, the permanent magnet sheet is adhered in the groove by means of silicone glue, and the silicone glue wraps the entire permanent magnet sheet.

[0007] Furthermore, the connecting rod includes an inclined section and a straight section, the straight section is parallel to the horizontal section of the L-shaped support plate, and the bottoms of the two are flush, and the inclined section is connected between the handle and the straight section.

[0008] Furthermore, the connecting rod also includes a connecting section, the middle part of which is connected to the handle, and a group of inclined sections, straight sections and L-shaped supporting plates which are connected in sequence are symmetrically arranged at both ends of the connecting section.

[0009] Furthermore, the connecting rod is formed by folding a section of steel pipe.

[0010] Furthermore, the handle is a section of a steel tube cylinder, and an end plate is welded to one end of the handle connected to the connecting rod, and the connecting rod is welded to the end plate.

[0011] The beneficial effects of the utility model are: the gasket locator utilizes an L-shaped support plate to receive and position the gasket plate, which can ensure the weld gap between the gasket plate and the welding base material, and the gasket plate is fixed on the L-shaped support plate by a permanent magnet sheet, and the placement position of the gasket plate can be flexibly adjusted by the gasket locator, and the gasket locator can be easily removed after the gasket plate is fixed by spot welding without affecting subsequent welding.

[0015] The utility model is further described below in conjunction with the accompanying drawings.

[0016] It should be noted that if there are directional indication terms in the present invention, such as up, down, left, right, front, and back directions and orientation terms, they are for the purpose of facilitating the description of the relative position relationship between components, and are not for the absolute position of the related components or the position relationship between components. They are only used to explain the relative position relationship and movement of the components in a certain posture. If the specific posture changes, the directional indication will also change accordingly. If there are terms related to quantity in the present invention, such as "multiple", "multiple", "several", etc., they specifically refer to two or more.

[0017] like Figure 1 , Figure 2As shown, a permanent magnetic pad positioner provided by the utility model comprises a handle 1, a connecting rod 2 and an L-shaped support plate 3 connected in sequence, the vertical section of the L-shaped support plate 3 is connected to the connecting rod 2 on the side facing away from the horizontal section, a groove 31 is provided on the horizontal section of the L-shaped support plate 3 on the side facing the vertical section, a permanent magnetic sheet 4 is fixedly provided in the groove 31, and the distance from the top of the permanent magnetic sheet 4 to the bottom of the L-shaped support plate 3 is the weld gap required between the two welding base materials. Because the weld gap is generally 2-3mm, the horizontal section of the L-shaped support plate 3 will be very thin, and it is best to use a metal sheet with higher strength. In order to avoid interference and facilitate positioning, the length of the L-shaped support plate 3 should not exceed the width of the pad plate 5, so that one end of the pad plate 5 can be placed on the vertical section of the L-shaped support plate 3 to achieve positioning of the pad plate 5 and the L-shaped support plate 3.

[0018] The use process of the utility model is: Figure 2 As shown, first place the liner plate 5 on the L-shaped support plate 3, then hold the handle 1 to push the L-shaped support plate 3 along the upper surface of the web 6 toward the bottom plate 7, so that the liner plate 5 abuts against the bottom plate 7, and then weld the liner plate 5 and the bottom plate 7 to fix them by spot welding, and finally pull the handle 1 outward to pull the L-shaped support plate 3 out of the gap between the liner plate 5 and the web 6 to complete the positioning and installation of the liner plate 5. The gap between the liner plate 5 and the web 6 is the weld area for subsequent single-sided welding and double-sided forming.

[0019] The permanent magnet sheet 4 can be made of neodymium iron boron permanent magnet material. Since the permanent magnet sheet 4 is relatively thin, it can be pasted in the groove 31 with silicone glue. In addition, the silicone glue is preferably wrapped around the entire permanent magnet sheet 4 to protect the permanent magnet sheet 4, reduce wear and tear, and extend its service life.

[0020] In order to facilitate holding the handle 1 and pushing the L-shaped support plate 3 along the lining plate 5, the connecting rod 2 includes an inclined section 21 and a straight section 22. The straight section 22 is parallel to the horizontal section of the L-shaped support plate 3, and the bottoms of the two are flush. The inclined section 21 is connected between the handle 1 and the straight section 22.

[0021] Furthermore, for some longer lining plates 5, one L-shaped support plate 3 may not be sufficient to ensure the installation accuracy of the lining plate 5. In this case, two or more lining positioners can be used for coordinated installation. For easy operation, the preferred solution is that the connecting rod 2 also includes a connecting section 23, the middle of which is connected to the handle 1, and a group of inclined sections 21, straight sections 22 and L-shaped support plates 3 connected in sequence are symmetrically arranged at both ends of the connecting section 23. The distance between the two L-shaped support plates 3 can be determined according to the length of the lining plate 5, preferably 1 / 3 of the length of the lining plate 5, so as to play a balanced support role.

[0022] When manufacturing the gasket positioner, the connecting rod 2 can be formed by folding a section of steel pipe. The handle 1 can be a section of steel pipe cylinder, and an end plate 11 is welded to one end of the handle 1 where it is connected to the connecting rod 2, and the connecting rod 2 is welded to the end plate 11.

[0023] The utility model uses the L-shaped support plate 3 to receive and position the gasket plate 5, which can ensure the weld gap between the gasket plate 5 and the welded base material. And the gasket plate 5 is fixed on the L-shaped support plate 3 through the permanent magnet sheet 4. The placement position of the gasket plate 5 can be flexibly adjusted by the gasket positioner. After the gasket plate 5 is fixed by spot welding, the gasket positioner can be easily taken out without affecting the subsequent welding. At the same time, the weld gap accuracy is ensured, and it has good practicability and application value.
