Description

Technical Field

[0001] The present application relates to the technical field of control cabinet processing equipment, and particularly relates to a welding positioning tool for the end nut of a cabinet support member. Background Art

[0002] The power control cabinet is an important part of the power system, and various electrical components are installed therein. Whether the outer shell structure of the power control cabinet is reasonable will directly affect the normal operation of the internal electrical components. The outer shell of the control cabinet generally consists of a top wall, a bottom wall, and two side walls. In some special application scenarios, support members need to be provided on the outer wall of the control cabinet shell to facilitate the connection of the control cabinet shell to the outside through the support members. To connect the support member to the cabinet body, it is necessary to involve the welding of the end nut of the connecting member. Before welding the end nut, it is necessary to position it to facilitate the welding work.

[0003] In response to this, most of the existing methods use manual placement to position the end nut, but this method has extremely low positioning accuracy and is prone to deviation, which in turn leads to a decrease in welding accuracy. Therefore, it is necessary to make improvements. Summary of the Utility Model

[0004] In order to solve the above deficiencies of the prior art, the present application provides a welding positioning tool for the end nut of a cabinet support member, which improves the positioning accuracy and facilitates welding.

[0005] To achieve the above object, the present utility model adopts the following technologies:

[0006] A welding positioning tool for the end nut of a cabinet support member includes a positioning plate. Starting from a point on the diagonal of its upper end face, two identically structured sliding grooves are respectively opened along the length direction and the width direction. Sliders are slidably installed in the sliding grooves. An internal thread hole is penetrated along the height direction in the slider. The slider is penetrated and connected with a first positioning member. The first positioning member includes a first positioning pin and a first screw rod arranged at the bottom of the first positioning pin. The first positioning pin is used for sleeving the end nut. The slider is connected with the first screw rod through the internal thread hole. When the first positioning member is locked with the slider, the bottom surface of the first screw rod abuts against the bottom surface of the sliding groove.

[0007] The beneficial effects of the present utility model are as follows: The cabinet support member is vertically placed on the positioning plate, ensuring its verticality and facilitating the cooperation with the end nut. Through the sliding fit of the slider in the sliding groove, on the one hand, the movement of the slider in the sliding groove can adapt to the positioning of various positions, and on the other hand, the fixed path of the slider moving in the sliding groove improves its positioning accuracy and is not prone to deviation. And the method of locking and fixing with the first positioning member after positioning is simple in structure and easy to operate while facilitating welding. Description of the Drawings

[0014] To make the objectives, technical solutions and advantages of the embodiments of the present utility model clearer, the following will describe the implementation manners of the present utility model in detail with reference to the accompanying drawings. However, the embodiments described in the present utility model are some embodiments of the present utility model, not all embodiments.

[0015] The embodiment of the present application provides an end nut welding positioning tooling for a cabinet support member, as shown in Figure 1 , Figure 2 and Figure 4 . It includes a positioning plate 1. Starting from a point on the diagonal line on its upper end face, two identically structured chutes 2 are respectively opened along the length direction and the width direction. A slider 3 is slidably installed in the chute 2. The opening of the chute 2 generally takes the longer side along the length direction and the width direction starting from the starting point as the standard, so as to better utilize the space on the positioning plate 1 and expand the moving range of the slider 3. An internal threaded hole is penetrated through the slider 3 along the height direction. The slider 3 is penetrated and connected with a first positioning member 4. The first positioning member 4 includes a first positioning pin 41 and a first screw rod 42 arranged at the bottom of the first positioning pin 41. The first positioning pin 41 is used for sleeving the end nut. The slider 3 is connected with the first screw rod 42 through the internal threaded hole. When the first positioning member 4 is locked with the slider 3, the bottom surface of the first screw rod 42 abuts against the bottom surface of the chute 2, and the fixation of the slider 3 can be realized.

[0016] Specifically, as shown in Figures 1 - 3As shown, with the starting point as the center of the circle, the positioning plate 1 is provided with a through fixing screw hole 11 for installing a second positioning member 5 corresponding to the fixing screw hole 11. The second positioning member 5 has the same structure as the first positioning member 4, and the second positioning member 5 is used to fix the positioning plate 1. After fixing a corner of the positioning plate 1 on a plane, when placing the cabinet support member and positioning the end nut, the positioning plate 1 will not slide, so as to avoid affecting the positioning accuracy and efficiency.

[0017] Specifically, as Figure 3 and Figure 4 shown, the top surface of the slider 3 is lower than the top opening of the chute 2, and the width of the chute 2 is smaller than the width of the end nut. When an end nut is sleeved outside the first positioning pin 41 and the end nut abuts against the two inner wall surfaces of the cabinet support member, the bottom surface of the end nut contacts the top surface of the positioning plate 1, which is used to make the bottom surface of the end nut flush with the bottom surface of the cabinet support member and is used to position the end nut in the vertical direction.

[0018] Specifically, the first positioning member 4 has various sizes to adapt to end nuts of different sizes. The sizes of the internal threaded holes of the end nuts to be welded are different, so first positioning pins 41 with different diameters are required to fit end nuts with different diameters. Since the first screw rod 42 is only threadedly connected to the slider 3, the sizes of the first screw rods 42 of different first positioning members 4 always remain unchanged.

[0019] Specifically, as Figures 1 - 3 shown, the chute 2 is an inverted T-shaped groove, and the slider 3 is an inverted T-shaped block, and the inverted T-shaped block is slidably fitted in the inverted T-shaped groove.

[0020] During application, as Figure 1 and Figure 4 shown, first place the positioning plate 1 on a plane, fix the positioning plate 1 by threadedly connecting the fixing screw hole 11 with the second positioning member 5, select the first positioning member 4 with a size corresponding to the end nut to be welded, then threadedly connect the first positioning member 4 with the slider 3 but do not lock it, and then sleeve the end nut outside the first positioning pin 41. Since the top surface of the slider 3 is lower than the top opening of the chute 2 and the width of the chute 2 is smaller than the width of the end nut, the bottom surface of the end nut will directly contact the top surface of the positioning plate 1. When the cabinet support member is placed on the positioning plate 1, the bottom surface of the cabinet support member will be flush with the bottom surface of the end nut, and the positioning of the end nut in the vertical direction can be realized more accurately.

[0021] Before or after that, place the cabinet support member on the positioning plate 1. When placing it, make the two end nuts to be welded located inside the cabinet support member. Then move the end nuts in the length direction and the width direction so that they are respectively in contact with the inner walls on both sides of the cabinet support member. Under the limitation of the triangle formed by the end nut moved in the length direction, the end nut moved in the width direction, and the first positioning member 4 installed on the fixed screw hole 11, reposition the placement of the cabinet support member so that its long side and wide side are parallel to the long side and wide side of the positioning plate 1 and the diagonals are collinear. While positioning the cabinet support member, the positioning of the end nuts is also achieved. Both end faces of the end nuts remain in contact with the inner walls of the cabinet support member, realizing the positioning of the end nuts in the horizontal direction.

[0022] At this time, as Figure 5 shown, the end nuts are placed in place, both of their end faces are in contact with the inner walls of the end support member, and the bottom surface is flush with the bottom surface of the end support member. Then use the first positioning member 4 to lock and fix the slider 3, and the welding work of the end nuts can be carried out.

[0023] With the above structure, by sliding the slider 3 in cooperation with the chute 2, then threadedly connecting with the first positioning member 4 but not locking it, and then sleeving the end nuts on the first positioning member 4, the movement of the end nuts in the horizontal direction and the positioning in the vertical direction can be realized. Vertically place the cabinet support member on the positioning plate 1, and under the limitation of the triangle formed by the second positioning member 5 and the two end nuts, the precise placement of the cabinet support member is realized. While positioning the cabinet support member, the positioning of the end nuts in the horizontal direction is also achieved. This setting not only has high positioning accuracy, but also the first positioning member 4 can not only sleeve the end nuts, but also fix the positioned end nuts, which is convenient for welding and avoids problems such as skew caused by welding the end nuts after manual placement. And the setting of the movement of the end nuts can not only perform positioning in multiple positions, but also realize the positioning of the cabinet support member on the positioning plate 1 while positioning itself, which is simple in structure and convenient to operate while ensuring the positioning accuracy.

[0024] In application, the above is only the preferred embodiment of the present application and is not used to limit the present application. Obviously, those skilled in the art can make various changes and modifications to the present application without departing from the spirit and scope of the present application.
