Description

Technical Field

[0001] The utility model belongs to the technical field of nut welding positioning jigs, and in particular relates to a preset nut welding positioning jig for cabinet doors. Background Art

[0002] In order to facilitate the installation of data boxes, fixed cables, various connection brackets and other components on the inner wall of the cabinet door of the electric control cabinet, nuts are usually preset on the inner wall of the common cabinet door by welding to connect various components. In the prior art, in order to unify the position of the preset nuts, it is necessary to determine the welding position of the nuts by measuring, marking, and punching before welding. This method is not only inefficient, but also even after punching, it is impossible to ensure that the nut is coaxial with the punched point when placing the nut, resulting in a deviation between the welding position of the nut and the designed position, and in severe cases, the connecting bolt will not be aligned with the nut. Utility Model Content

[0003] In order to solve the deficiencies in the prior art, the utility model provides a cabinet door preset nut welding positioning fixture, which can effectively improve the positioning efficiency and positioning accuracy of the nut.

[0004] In order to achieve the purpose of this utility model, the following scheme is proposed:

[0005] A cabinet door preset nut welding positioning fixture comprises: two hinge plates, opposite ends of which are connected by a hinge rod, the hinge rod is parallel to the width direction of the hinge plates, and the hinge rod is movably arranged along the axial direction, when the two hinge plates are flattened, the distance between the far ends of the two hinge plates is the same as the distance between one pair of side edges of the cabinet door, the hinge plates are all provided with support plates movably arranged along the length direction, the distance between the bottom surface of the support plate and the bottom surface of the hinge plate is greater than the thickness of the nut, and the end of the support plate located outside the hinge plate is penetrated by a top rod perpendicular to the bottom surface of the hinge plate, and the lower end of the top rod matches the inner hole of the nut.

[0006] The beneficial effect of the utility model is that the fixture can directly position and tighten the nut, which not only reduces the steps of measurement and marking, improves the positioning efficiency, but also has higher positioning accuracy. BRIEF DESCRIPTION OF THE DRAWINGS

[0013] In order to make the purpose, technical solutions and advantages of the embodiments of the utility model clearer, the implementation methods of the utility model are described in detail below in conjunction with the accompanying drawings, but the embodiments described in the utility model are only part of the embodiments of the utility model, rather than all the embodiments.

[0014] like Figures 1 to 4 As shown, a cabinet door preset nut welding positioning fixture comprises: two hinge plates 1, whose opposite ends are connected by a hinge rod 2, the hinge rod 2 is parallel to the width direction of the hinge plate 1, and the hinge rod 2 is movably set along the axial direction, when the two hinge plates 1 are flattened, the distance between the far ends of the two hinge plates 1 is the same as the distance between one pair of side edges of the cabinet door, the cabinet door of the electric control cabinet is usually bent inwardly to ensure the stability of the structure and prevent the sharp edges from being exposed, and side panels and grooves are formed around the cabinet door, the hinge plates 1 are all provided with support plates 3 moving along the length direction, the distance between the bottom surface of the support plate 3 and the bottom surface of the hinge plate 1 is greater than the thickness of the nut, and the end of the support plate 3 located outside the hinge plate 1 is penetrated by a top rod 4 perpendicular to the bottom surface of the hinge plate 1, and the lower end of the top rod 4 matches the inner hole of the nut.

[0015] When using, Figure 1As shown, first, the two hinge plates 1 are folded into an arched structure around the hinge rod 2 to facilitate the two ends of the jig to be stuck in the grooves on the side of the cabinet door; then the distal ends of the hinge plates 1 are slid along the inner wall of the cabinet door until the distal ends of the two hinge plates 1 are stuck in the grooves on the opposite sides of the cabinet door. Because when the two hinge plates 1 are flattened, the distance between the distal ends of the two hinge plates 1 is the same as the distance between one pair of side edges of the cabinet door. Therefore, the two hinge plates 1 are in a flattened state at this time, and the bottom surfaces of the hinge plates 1 are in contact with the inner wall of the cabinet door. Then, the axial position of the hinge rod 2 is adjusted, and it can also be adjusted in the early stage. Taking one end of the hinge rod 2 as a reference, the distance between the end surface and the top rod 4 is measured. After the two hinge plates 1 are flattened, the jig is moved along the axial direction of the hinge rod 2 so that the end of the hinge rod 2 used as a reference is connected with the other side plate of the cabinet door. Touch; adjust the position of the support plate 3 along the length direction of the hinge plate 1, or adjust the position of the support plate 3 before installing the jig; when the two hinge plates 1 are flattened and one end of the hinge rod 2 as a reference is in contact with the other side plate of the cabinet door, the position below the push rod 4 is the welding position of the nut, and then the nut is placed under the push rod 4, and the lower end of the push rod 4 is inserted into the nut, so as to achieve the purpose of limiting the nut, and finally weld between the outer bottom surface of the nut and the inner wall of the cabinet door; for cabinet doors of the same specification, the position of the hinge rod 2 and the support plate 3 can be adjusted before use, and only the jig needs to be installed and removed in subsequent welding, which not only saves the operation process of each adjustment, but also avoids operations such as measurement, marking, and punching, which can effectively save welding time and effectively ensure the position accuracy of the nut.

[0016] Preferably, Figure 1 As shown, the distal end of the hinge plate 1 is provided with an extension plate 11 along the width direction to increase the contact area with the cabinet door side plate, thereby preventing the unfolded hinge plate 1 from tilting relative to the side of the cabinet door for contacting the hinge rod 2 .

[0017] Preferably, Figure 1 , Figure 3 As shown, a slide groove 12 is provided on the top surface of the hinge plate 1 along the length direction, one end of the support plate 3 is slidably disposed in the slide groove 12 , and the support plate 3 is provided with a locking screw 31 for fixing the position of the support plate 3 on the hinge plate 1 .

[0018] Preferably, Figure 2 As shown, the outer sleeve of the hinge rod 2 is provided with a pipe sleeve, and the pipe sleeve is simultaneously passed through the two hinge plates 1, and retaining rings 21 are provided at both ends of the pipe sleeve. The two hinge plates 1 are located between the two retaining rings 21 to prevent the hinge plates 1 from falling off. In this way, the two hinge plates 1 can form an integral structure and move together along the length direction of the hinge rod 2 to facilitate the adjustment of the position of the hinge rod 2.

[0019] Preferably, Figure 2As shown, a clamping screw 22 is provided through the side wall of the retaining ring 21 for fixing the hinge rod 2 .

[0020] Preferably, Figure 3 As shown, a conical head 41 is provided at the lower end of the push rod 4, and the conical bottom faces the bottom surface of the hinge plate 1. The conical head 41 can be used to adapt to nuts with different inner hole sizes to increase the practicality of the fixture.

[0021] Further preferably, Figure 3 As shown, a spring 42 is provided between the top of the conical head 41 and the bottom surface of the support plate 3 for applying downward pressure to the push rod 4 so that the conical head 41 automatically presses the nut.

[0022] Further preferably, Figure 3 As shown, the spring 42 is a cylindrical spring structure, which is sleeved on the outside of the push rod 4.

[0023] The above is only a preferred embodiment of the utility model, and does not mean that it is the only one or limit the utility model. Those skilled in the art should understand that various changes or equivalent replacements made to the utility model without departing from the scope of the utility model are within the scope of protection of the utility model.
