Description

Technical Field

[0001] This utility model belongs to the field of process equipment, specifically a data acquisition box hanging ear installation and positioning tooling. Background Technology

[0002] The data acquisition box has four mounting ears on the back that need to be welded for installation. Due to the strict requirements on dimensions, the mounting ears without a fixed structure are prone to tilting during welding, causing dimensional deviations and making it unusable. In addition, manual re-welding of dimensions is slow.

[0003] For example, Chinese patent CN217045203U discloses a welding fixture for junction box lugs, including a base frame, lugs, a junction box, a pin, and base frame holes. The base frame of this welding fixture is a bent cross-shaped base plate with two base frame holes. In use, a T-shaped pin is inserted into the base frame holes to fix the junction box. The lugs to be welded are placed at the included angle of the cross shape of the base frame, close to the junction box, to complete the welding. The lug welding fixture provided by the above utility model can quickly and accurately position the four lugs on the back of the junction box in one go. However, its overall size is relatively large. For large boxes, the fixture size is too large, making it inconvenient to manufacture and use. Furthermore, the fixture in the above utility model requires the box to be facing down, which is inconvenient for boxes with protruding parts on the front. Utility Model Content

[0004] To address the issues of existing cabinet mounting lug welding fixtures having large overall dimensions and requiring the cabinet to be placed face down during use, this utility model proposes a data acquisition cabinet mounting lug installation and positioning fixture with a compact size, and which eliminates the need to set the cabinet's posture during lug positioning and welding.

[0005] To achieve the above-mentioned technical effects, this utility model proposes: A data acquisition box mounting and positioning fixture includes: The first positioning plate includes a horizontal positioning plate and a vertical positioning plate that are perpendicular to each other; The second positioning plate is fixedly connected to the first positioning plate and includes a hook mating surface, wherein the hook mating surface is perpendicular to the horizontal positioning plate and the vertical positioning plate respectively. Both the height plate and the width plate are connected to the second positioning plate and cooperate with the ear mating surface to form an ear positioning groove.

[0006] The first positioning plate and the second positioning plate of this utility model are perpendicular to each other. The first positioning plate restricts two vertical degrees of freedom of the hanging ear through the horizontal positioning plate and the vertical positioning plate. In use, the hanging ear is attached to the hanging ear mating surface of the second positioning plate. The hanging ear positioning groove formed by the height plate and the width plate restricts one vertical degree of freedom and the rotational degree of freedom of the hanging ear on the hanging ear mating surface, thus completing the positioning of the hanging ear in the data acquisition box.

[0007] The first positioning plate and the second positioning plate are formed by bending the same sheet metal; the height plate and the width plate are respectively formed by bending the edge of the second positioning plate.

[0008] The mating surface between the vertical positioning plate and the data acquisition box is on the same plane as the mating surface between the width plate and the hanging ear.

[0009] The second positioning plate also includes a plurality of height adjustment holes and width adjustment holes arranged in a row. The height adjustment holes and width adjustment holes are all strip-shaped, and any one of the height adjustment holes is perpendicular to any one of the width adjustment holes.

[0010] The height plate and width plate include a plate body, a pair of buckles connected to the plate body, the buckles cooperating with the height adjustment hole or width adjustment hole to fix the plate body to the hanging ear mating surface, and also include a protrusion that abuts against the hanging ear mating surface.

[0011] The buckle includes a buckle body and a buckle head, and a buckle head and the plate body form a buckle groove.

[0012] The height plate is detachably connected to the height adjustment hole, and the width plate is detachably connected to the width adjustment hole.

[0013] The horizontal positioning plate has two vertically aligned grooves. The vertical fixing plate includes the plate body, a buckle, and a protrusion. The vertical fixing plate is detachably connected to the vertical grooves.

[0014] The height of both the height plate and the width plate is greater than the thickness of the lug.

[0015] The beneficial effects of this utility model are: 1. Compact size; 2. Easy to use, positioning and installation can be completed by one hand; 3. Features a detachable structure for the height and width plates, providing greater flexibility. Attached Figure Description

[0024] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification.

[0025] This utility model provides a data acquisition box mounting and positioning fixture, and the preferred embodiment of the data acquisition box mounting and positioning fixture is described below.

[0026] Example 1 This embodiment provides a mounting and positioning fixture for a data acquisition box, see attached document. Figure 1 It includes a first positioning plate 100, a second positioning plate 200, a height plate 300, and a width plate 400. Specifically, the first positioning plate 100 includes a horizontal positioning plate 101 and a vertical positioning plate 102 that are perpendicular to each other; the second fixing plate is fixedly connected to the first positioning plate 100 and includes a hook mating surface 201, which is perpendicular to both the horizontal positioning plate 101 and the vertical positioning plate 102; the height plate 300 and the width plate 400 are both connected to the second positioning plate 200 and cooperate with the hook mating surface 201 to form a hook 600 positioning groove.

[0027] In this embodiment, the first positioning plate 100 and the second positioning plate 200 are formed by bending the same sheet metal. During the forming process of the first positioning plate 100 and the second positioning plate 200, it is necessary to cut one side of the extension line of the connecting edge between the first positioning plate 100 and the second positioning plate 200 to leave a plate surface for forming the vertical positioning plate 102 and the width plate 400. The first positioning plate 100 is bent to form an L-shaped structure, with the two ends of the L-shaped structure being a horizontal positioning surface and a vertical positioning surface, respectively. The horizontal positioning plate 101 is directly connected to the first positioning plate 100.

[0028] In this embodiment, the height plate 300 and the width plate 400 are respectively formed by bending the edges of the second positioning plate 200. The top edge of the second positioning plate 200 and one side edge near the vertical positioning plate 102 are bent to form the height plate 300 and the width plate 400, respectively. The height plate 300 and the width plate 400 cooperate with the lug mating surface 201 to form the positioning groove of the lug 600. The height plate 300 and the width plate 400 are respectively used to abut against the two vertical edges of the lug 600, and the lug mating surface 201 is used to cooperate with one side surface of the lug 600.

[0029] In this embodiment, the height dimensions of both the height plate 300 and the width plate 400 are greater than the thickness dimension of the hanging ear 600, ensuring that the height plate 300 and the width plate 400 effectively cooperate and are positioned with the hanging ear 600. In this embodiment, the hanging ear 600 is rectangular with right-angled corners. In some other embodiments of this embodiment, the hanging hole end of the hanging ear 600 can be set as round.

[0030] Reference Appendix Figure 2 and 3 Using the XYZ coordinate system in the figure, the top surface of the data acquisition box 500 is denoted as the XY plane, and the two sides are the XZ plane and the YZ plane, respectively. Using the mounting and positioning fixture for the ear 600 in this embodiment, the ear 600 is welded to the XZ surface of the data acquisition box 500. The hanging hole end of the ear 600 is aligned with the ear mating surface 201. One corner of the hanging hole end is pushed towards the corner formed between the height plate 300 and the width plate 400. At this time, the ear 600 and the fixture are positioned. The horizontal positioning plate 101 of the fixture is aligned with the top surface of the data acquisition box 500, i.e., the XY surface. The vertical positioning plate 102 is aligned with the YZ surface of the data acquisition box 500. The welding end of the ear 600 facing the first positioning plate 100 is aligned with the XZ surface of the data acquisition box 500. The welding position of the ear 600 in the data acquisition box 500 is positioned. The ear 600 is then welded to the data acquisition box 500 to complete the installation of the ear 600.

[0031] In this embodiment, the width plate 400, which mates with the hanging ear 600, is on the same plane as the surface of the vertical positioning plate 102 that mates with the data acquisition box 500. When the hanging ear 600 completes its positioning with the data acquisition box 500, the side of the hanging ear 600 that is in contact with the width plate 400 is parallel to the YZ plane of the data acquisition box 500. The bent edge between the first positioning plate 100 and the second positioning plate 200, and the bent edge of the height plate 300 on the second positioning plate 200, are set according to the preset extension length of the hanging hole end of the hanging ear 600.

[0032] In some other embodiments of this example, the welding position of the ear 600 is closer to the midpoint of the edge between the XY plane and the XZ plane of the data acquisition box 500, and the length of the horizontal positioning plate 101 is increased so that the position of the positioning groove of the ear 600 is closer to this midpoint of the edge.

[0033] In this embodiment, four hanging ears 600 need to be welded to the welding surface of the data acquisition box 500. Another tooling is needed that is symmetrically arranged with the mounting and positioning tooling of the hanging ears 600 in this embodiment. The tooling width plate 400 and the vertical positioning plate 102 in this embodiment are respectively set on the other side of the second positioning plate 200 and the horizontal positioning plate, so that they can cooperate with the tooling in this embodiment to perform positioning welding on the four hanging ears 600 respectively.

[0034] The data acquisition box mounting and positioning fixture in this embodiment has a clever structure that allows for the positioning of the mounting ear welding position without measuring the mounting ear position.

[0035] Example 2 The data acquisition box mounting and positioning fixture in Embodiment 1 is convenient to use. When it is necessary to weld the mounting ears 600 at all four corners of the same welding surface, they need to be used in pairs. This embodiment further optimizes the mounting and positioning fixture for the mounting ears 600 by setting a detachable structure of the height plate 300, the width plate 400 and the vertical positioning plate 102. The mounting ears 600 can be welded at all four corners of the same welding surface using one fixture.

[0036] This embodiment proposes a mounting and positioning fixture for a data acquisition box, as shown in the attached document. Figure 4 It includes a first positioning plate 100, a second positioning plate 200, a height plate 300, and a width plate 400. Specifically, the first positioning plate 100 includes a horizontal positioning plate 101 and a vertical positioning plate 102 that are perpendicular to each other; the second fixing plate is fixedly connected to the first positioning plate 100 and includes a hook mating surface 201, which is perpendicular to both the horizontal positioning plate 101 and the vertical positioning plate 102; the height plate 300 and the width plate 400 are both connected to the second positioning plate 200 and cooperate with the hook mating surface 201 to form a hook 600 positioning groove.

[0037] In this embodiment, the first positioning plate 100 and the second positioning plate 200 are formed by bending the same plate. First, the two sides of the preset bending position of the first positioning plate 100 and the second positioning plate 200 are cut to ensure that the first positioning plate 100 and the second positioning plate 200 will not squeeze each other after bending. After bending, the first positioning plate 100 and the second positioning plate 200 are perpendicular.

[0038] In this embodiment, the second positioning plate 200 further includes a plurality of height adjustment holes 202 and width adjustment holes 203 arranged in a row. Both the height adjustment holes 202 and width adjustment holes 203 are strip-shaped, and each height adjustment hole 202 is perpendicular to each width adjustment hole 203. Both the height adjustment holes 202 and width adjustment holes 203 are elongated rectangular strips, penetrating the second positioning plate 200 along its thickness direction. In this embodiment, the length and width of the height adjustment holes 202 and width adjustment holes 203 are the same.

[0039] Specifically, in this embodiment, two width adjustment holes 203 are respectively provided on both sides of the second positioning plate 200, and two height adjustment holes 202 are provided above the second positioning plate 200. The height adjustment holes 202 and width adjustment holes 203 are perpendicular to each other. The height plate 300 and width plate 400 are detachably connected to the height adjustment holes 202 and width adjustment holes 203, respectively. By connecting the height plate 300 to the height adjustment holes 202 at different positions, the protrusion height of the hanging end of the lug 600 can be changed, adapting to various lugs 600. By connecting the width plate 400 to the width adjustment holes 203 at different positions on the same side, the welding position of the lug 600 and the data acquisition box 500 can be changed. By connecting the width plate 400 to the width adjustment holes 203 on different sides, the lugs 600 on opposite sides can be welded.

[0040] In this embodiment, the height plate 300 and the width plate 400 include a plate body 301, a pair of buckles 302 connected to the plate body 301, the buckles 302 cooperate with the height adjustment hole or the width adjustment hole 203 to fix the plate body 301 to the ear mating surface 201, and also include a protrusion 306 that abuts against the ear mating surface 201.

[0041] In this embodiment, the buckle 302 includes a buckle body 303 and a buckle head 304, and a buckle groove 305 is formed between the buckle head 304 and the plate body 301. The distance between the buckle grooves 305 of the two opposite buckles 302 on the plate body 301 is equal to the length of the adjustment hole.

[0042] Specifically, in this embodiment, the height plate 300 and the width plate 400 have the same structure and dimensions. (See attached diagram.) Figure 4 and 7Taking the height plate 300 as an example, the width of the plate body 301 is the same as that of the height adjustment hole 202, while its length is slightly larger than that of the height adjustment hole 202. Two latches 302 are provided on one long side. Each latch 302 has a latch body 303 and a latch head 304. The latch body 303 connects the latch head 304 to the height plate 300. A groove 305 is formed between the latch head 304 and the plate body 301. The width of the groove 305 is the same as the thickness of the second positioning plate 200. The latch heads 304 of the two latches 302 are positioned back-to-back, with the latch heads 304 only slightly protruding from the groove 305, meaning the length of the latch heads 304 is smaller. The ends of the latch heads 304 are chamfered to facilitate the engagement of the height plate 300. When the buckles 302 of the height plate 300 are inserted into the height adjustment hole 202, the chamfering causes the buckle bodies 303 of the two buckles 302 to deform in a direction closer to each other. Because the length of the buckle heads 304 is small, the deformation of the buckle bodies 303 is small, allowing both buckle bodies 303 to easily extend into the height adjustment hole 202. When the side of the plate body 301 containing the buckles 302 abuts against the surface of the second positioning plate 200, the two buckle heads 304 protrude from the openings, and simultaneously the two slots 305 abut against the inner two wide sides of the height adjustment hole 202, completing the engagement between the height plate 300 and the height adjustment hole 202. The structural configuration of the width plate 400, its connection method with the width adjustment hole 203, and its relationship are described above for the height plate 300 and the height adjustment hole 202.

[0043] It should be noted that one side of the protrusion 306 should face away from the hanging ear 600. While ensuring the vertical angle between the height plate 300 and the second positioning plate 200, the protrusion 306 will not affect the positioning size and position of the hanging ear 600.

[0044] When disassembling the height plate 300 and the height adjustment hole 202, the two clips 304 can be manually squeezed to easily remove the two clips 302 and remove the height plate 300 from the height adjustment hole 202.

[0045] In this embodiment, the horizontal positioning plate 101 has two vertical docking grooves 103 arranged opposite to each other, and the vertical positioning plate 102 includes a plate body 301, a buckle 302 and a protrusion 306. The vertical positioning plate 102 is detachably connected to the vertical docking groove 103.

[0046] Specifically, a vertical docking groove 103 is provided on each of the two sides of the horizontal positioning plate 101, with a structure similar to the height adjustment hole 202 described above. The vertical docking hole is detachably connected to the vertical positioning plate 102. The structures of the vertical docking groove 103 and the vertical positioning plate 102 are similar to those of the height plate 300 and the height adjustment hole 202 described above.

[0047] Reference Appendix Figure 5 and 6Using the XYZ coordinate system in the figure, the top surface of the data acquisition box 500 is denoted as the XY plane, and the two sides are the XZ plane and YZ plane, respectively. Using the mounting and positioning fixture of the lug 600 in this embodiment, the lug 600 is welded to the XZ plane of the data acquisition box 500. The height plate 300 is engaged with the height adjustment hole 202, the width plate 400 is engaged with the width adjustment hole 203 on the right side, and the vertical positioning plate 102 is engaged with the vertical docking groove 103 on the right side. Align the hanging hole end of the lug 600 with the lug mating surface 201, and push one corner of the hanging hole end towards the corner formed between the height plate 300 and the width plate 400. At this point, the lug 600 and the fixture are positioned. Align the horizontal positioning plate 101 of the fixture with the top surface (XY surface) of the data acquisition box 500, and align the vertical positioning plate 102 with the YZ surface of the data acquisition box 500. Align the welding end of the lug 600 with the surface of the first positioning plate 100 and the XZ surface of the data acquisition box 500. This completes the welding position positioning of the lug 600 in the data acquisition box 500. Maintain the positioning position of the lug 600 and weld the lug 600 onto the data acquisition box 500 to complete the installation of the lug 600.

[0048] When welding the hanging ear 600 on the other side of the XZ surface of the data acquisition box 500, the width plate 400 and the vertical positioning plate 102 are disassembled and then fixed to the width adjustment hole 203 and the vertical docking groove 103 on the left side, respectively, and then welding can be performed.

[0049] In this embodiment, the mounting and positioning fixture for the data acquisition box uses a detachable connection method for the height plate, width plate, and vertical positioning plate. The same fixture can be used to weld the mounting ears on both sides of the 500 welding surface of the data acquisition box, which is more flexible than the first embodiment.

[0050] The above description is a preferred embodiment of the present utility model, used to illustrate the specific structure and function of the present utility model. It should be noted that, without departing from the principle of the present utility model, those skilled in the art can make foreseeable improvements and modifications to the present utility model, and these improvements and modifications are also within the protection scope of the present utility model.
