Description

Technical Field

[0001] This utility model relates to the field of tooling technology, and in particular to a tooling for assembling protective shells. Background Technology

[0002] To prevent safety accidents caused by electrical devices such as circuit breakers being exposed to the external environment, existing electrical equipment is usually fitted with an openable protective shell. This protective shell generally consists of a base and a cover, which typically require pre-assembly before being installed onto the electrical equipment. Because the outer surface of the cover has a curved structure, it is prone to wobbling on the workbench during pre-assembly, affecting the assembly accuracy between it and the base and reducing assembly efficiency. Furthermore, the direct contact between the cover's outer surface and the workbench also makes it susceptible to surface wear during assembly. Utility Model Content

[0003] In view of the above-mentioned shortcomings of the existing technology, the technical problem to be solved by this utility model is to propose a tooling for assembling protective shells that can improve the assembly accuracy and efficiency of protective shells and prevent wear of the cover during the assembly process.

[0004] The technical solution adopted by this utility model to solve its technical problem is to provide a tooling for assembling a protective shell. The protective shell includes a base and a cover. The cover has an arcuate protrusion and a mounting edge connected to the base. The tooling includes:

[0005] The main body has a mounting groove along its length for accommodating a cover;

[0006] The first support surface is horizontally arranged in the mounting groove and extends along the length of the mounting groove. There is a height difference between the first support surface and the bottom wall of the mounting groove. By fixing the mounting edge to the first support surface, the cover can be fixed in the mounting groove in a horizontal state, so that there is a first gap between the arc-shaped protrusion and the bottom wall of the mounting groove.

[0007] Furthermore, the mounting groove is connected to the outside world, and a first step is provided along its length. A first support surface is provided on the first step, and the height of the first step is greater than the height of the arc-shaped protrusion.

[0008] Furthermore, the first step has a built-in magnetic attraction component and / or the surface of the first step is provided with a magnetic attraction layer.

[0009] Furthermore, the first step is provided with one or more mounting holes. When there are multiple mounting holes, they are arranged along the length of the first step, and the mounting edge can be connected to the mounting hole by fasteners.

[0010] Furthermore, the mounting edge facing the mounting groove is provided with one or more first connecting structures, and the first step is provided with one or more first clearance grooves that correspond one-to-one with the first connecting structures and are adapted in shape.

[0011] Furthermore, the size of the first clearance groove is larger than the size of the first connecting structure, and when the first connecting structure is inside the first clearance groove, there is a second gap between the first connecting structure and the bottom wall of the first clearance groove.

[0012] Furthermore, the mounting groove is also provided with a second step arranged opposite to the first step, and the second step is provided with a second support surface along the length direction; when the base is closed on the cover, the second support surface abuts against the base.

[0013] Furthermore, the cover has one or more second connecting structures on the side away from the mounting edge, and the second step has one or more second clearance grooves that correspond one-to-one with the second connecting structures and are adapted in shape along the length direction.

[0014] Furthermore, the size of the second clearance groove is larger than the size of the second connecting structure, and when the second connecting structure is inside the second clearance groove, there is a third gap between the second connecting structure and the bottom wall of the second clearance groove.

[0015] Furthermore, the mounting groove is also provided with a first limiting surface and a second limiting surface arranged opposite to each other. The first limiting surface and the second limiting surface are perpendicular to the first step and the second step, respectively. The straight-line distance between the first limiting surface and the second limiting surface is adapted to the width of the base.

[0016] Compared with the prior art, the present invention has at least the following beneficial effects:

[0017] 1. In this utility model, the main body of the tooling has a mounting groove arranged along its length, and a first support surface horizontally disposed within the mounting groove and extending along the length of the mounting groove, with a height difference between the first support surface and the bottom wall of the mounting groove. This design, through the cooperation of the mounting groove and the first support surface, enables the cover to remain horizontal during assembly and forms a first gap between the cover and the bottom wall of the mounting groove, thereby effectively preventing the cover from shaking during assembly, improving the efficiency and accuracy of docking with the base, and also avoiding wear on the cover surface due to contact, ensuring its appearance integrity and functional reliability.

[0018] 2. In this utility model, a first step is provided along the length direction inside the mounting groove, and a first supporting surface is provided on the first step, with the height of the first step being greater than the height of the arc-shaped protrusion. This design enhances the load-bearing capacity and stability of the first supporting surface, ensuring that the first supporting surface can provide reliable support, while making the arc-shaped protrusion completely suspended, avoiding contact with the bottom wall of the mounting groove, thereby reducing the risk of wear and improving assembly accuracy.

[0019] 3. In this utility model, the first step has a built-in magnet or a magnetic layer on its surface. This design allows the metal cover to be stably attached to the tooling through magnetic attraction without the need for additional fixing structures, thereby effectively preventing positioning deviations caused by shaking or offset during assembly.

[0032] like Figures 1 to 5 As shown, in this embodiment, a tooling for assembling a protective shell 500 is provided. The protective shell 500 includes a base 510 and a cover 520. The cover 520 has an arcuate protrusion 521 and a mounting edge 522 connected to the base 510. The tooling includes:

[0033] The main body 100 has a mounting groove 110 along its length for accommodating the cover 520.

[0034] The first support surface 210 is horizontally arranged within the mounting groove 110 and extends along the length of the mounting groove 110, with a height difference between the first support surface 210 and the bottom wall of the mounting groove 110. By fixing the mounting edge 522 to the first support surface 210, the cover 520 can be fixed horizontally within the mounting groove 110, and a first gap 300 is formed between the arc-shaped protrusion 521 and the bottom wall of the mounting groove 110. This design, through the cooperation between the mounting groove 110 and the first support surface 210, ensures that the cover 520 remains horizontal during assembly, and the first gap 300 between the cover 520 and the bottom wall of the mounting groove 110 effectively prevents the cover 520 from shaking during assembly, improving the efficiency and accuracy of docking with the base 510, and also avoids wear on the surface of the cover 520 due to contact, ensuring its appearance integrity and functional reliability.

[0035] Specifically, in this embodiment, the tooling is mainly used to fix the cover 520 of the protective shell 500 so that the base 510 and the cover 520 can be assembled efficiently and accurately. Figure 3 As shown, the protective housing 500 mainly consists of a base 510 and a cover 520. The base 510 is rectangular and serves as the connection component between the protective housing 500 and the electrical equipment. It typically has multiple connection holes for fixing to the housing or other components of the electrical equipment. The cover 520 is box-shaped with an inwardly protruding receiving cavity specifically designed to accommodate electrical devices such as air switches. The sides of this receiving cavity are inclined towards the centerline, forming an arc-shaped protrusion 521 on the outer side of the cover 520 to enhance its overall aesthetics and structural strength. Furthermore, the cover 520 also has a strip-shaped mounting edge 522 extending along its length, which serves as a connecting component for fixing the cover 520 to the base 510.

[0036] In this embodiment, the cover 520 is provided with a plurality of first connecting structures 523 and second connecting structures 524 of different shapes on both sides. The plurality of first connecting structures 523 are arranged at intervals on the side of the mounting edge 522 facing the mounting groove 110 so that the cover 520 and the base 510 can be fixedly connected. The plurality of second connecting structures 524 are arranged at intervals on the side of the arc-shaped protrusion 521 away from the mounting edge 522 so that the cover 520 and the base 510 can be rotatably connected.

[0037] like Figures 1 to 5As shown, in this embodiment, the body 100 is rectangular, with a length greater than that of the protective shell 500, to accommodate protective covers of different specifications, effectively improving the versatility of the tooling. Furthermore, the body 100 has a mounting groove 110 along its length that matches the shape of the protective shell 500. This mounting groove 110 is open on three sides and communicates with the outside, facilitating the insertion and removal of the cover 520 by operators. This design can accommodate and define the position of the cover 520, ensuring that the cover 520 will not shift or wobble during assembly.

[0038] In this embodiment, a horizontally arranged first support surface 210 is provided within the mounting groove 110. The first support surface 210 is strip-shaped and extends along the length of the mounting groove 110, with a height difference between the first support surface 210 and the bottom wall of the mounting groove 110. This design ensures that the cover 520 remains horizontal when placed within the mounting groove 110, and also creates a first gap 300 between the arc-shaped protrusion 521 and the bottom wall of the mounting groove 110, preventing contact between the arc-shaped protrusion 521 and the bottom wall of the mounting groove 110, thereby reducing the risk of surface wear on the cover 520.

[0039] In this embodiment, a first step 200 is provided along the length of one side of the mounting groove 110. The first step 200 is rectangular, with its top surface being a horizontal plane, parallel to the bottom wall of the mounting groove 110, and having a right-angled edge. A first support surface 210 is disposed on this horizontal plane to support the mounting edge 522 of the cover 520, and the height of the first step 200 is greater than the height of the arc-shaped protrusion 521 on the cover 520. This design not only provides a stable load-bearing foundation for the first support surface 210, enhancing the overall strength and rigidity of the support structure, but also ensures that the arc-shaped protrusion 521 of the cover 520 is completely suspended during assembly by reasonably setting the step height, avoiding contact with the bottom wall of the mounting groove 110. In this way, scratches or wear on the arc-shaped protrusion 521 caused by friction or compression are effectively prevented during assembly, thereby improving the appearance quality and product consistency of the cover 520.

[0040] In this embodiment, the first step 200 has a built-in magnetic attraction component (not shown in the figure) and / or the surface of the first step 200 is provided with a magnetic attraction layer (not shown in the figure). The magnetic attraction component has a structure with a permanent magnet, an electromagnet, or a ferrite magnet. This design allows the metal cover 520 to be stably attracted to the tooling through magnetic attraction without the need for an additional fixing structure, thereby effectively preventing positioning deviations caused by shaking or displacement during assembly.

[0041] In this embodiment, the first step 200 is provided with one or more mounting holes 220. When there are multiple mounting holes 220, they are arranged at intervals along the length of the first step 200, and the mounting edge 522 can be connected to the mounting hole 220 by fasteners. This design allows the cover 520 made of non-magnetic materials (such as non-magnetic plastic, stainless steel, or aluminum alloy, or other materials not suitable for magnetic fixation) to be reliably positioned and fixed by mechanical connection, thereby effectively preventing positioning deviation problems caused by shaking or offset during assembly, and further improving assembly accuracy and consistency.

[0042] Preferably, in this embodiment, the fastener is a screw or bolt.

[0043] Preferably, in this embodiment, the mounting hole 220 has two holes, both of which are threaded holes. The threaded hole structure not only ensures a secure connection and easy disassembly, but also helps improve positioning accuracy, making it suitable for applications requiring high assembly stability.

[0044] In this embodiment, the first step 200 is further provided with one or more first clearance grooves 230 that correspond one-to-one with the first connecting structure 523 and are adapted in shape. The multiple first clearance grooves 230 are arranged at intervals along the length of the first step 200 and are recessed from top to bottom along the first support surface 210. This design allows the first connecting structure 523 on the mounting edge 522 of the cover 520 to be precisely embedded in the corresponding first clearance groove 230 during assembly, thereby effectively avoiding interference between the first connecting structure 523 and the tooling, and preventing structural deformation or damage caused by collision or compression. At the same time, this design also helps to improve the positioning accuracy of the cover 520 on the tooling, ensuring stable assembly posture and accurate positioning.

[0045] Preferably, in this embodiment, the first clearance groove 230 is cylindrical, rectangular, or square, and can be set according to actual needs.

[0046] In this embodiment, the size of the first clearance groove 230 is larger than the size of the first connecting structure 523. This design allows the tooling to be adapted to different models of protective housings 500, as the length or position of the first connecting structure 523 may differ between different models of protective housings 500. This effectively improves the versatility and adaptability of the tooling.

[0047] In this embodiment, when the first connecting structure 523 is located within the first clearance groove 230, a second gap 310 exists between the first connecting structure 523 and the bottom wall of the first clearance groove 230. This design prevents the first connecting structure 523 from being squeezed by the tooling during assembly, thereby effectively preventing the first connecting structure 523 from deforming or being damaged due to force, ensuring its structural integrity and the realization of subsequent assembly functions.

[0048] In this embodiment, a second step 400 is also provided on the other side of the mounting groove 110, which is arranged opposite to the first step 200. The second step 400 has a second support surface 410 along its length. When the base 510 is closed on the cover 520, the second support surface 410 abuts against the base 510. This design provides further support for the base 510, ensuring that the base 510 maintains a stable posture during assembly and avoiding tilting or displacement due to gravity or external forces.

[0049] Preferably, in this embodiment, the second step 400 is trapezoidal, with its top surface being an inclined surface. The inclination angle matches the outer contour of the base 510, and the second support surface 410 is disposed on the inclined surface. This design ensures that the second support surface 410 can better fit the outer contour of the base 510, improving the reliability of the support.

[0050] In this embodiment, the second step 400 is further provided with one or more second clearance grooves 420 that correspond one-to-one with the second connecting structure 524 and are adapted in shape. The multiple second clearance grooves 420 are arranged at intervals along the length of the second step 400 and are respectively recessed from top to bottom along the second support surface 410. This design allows the second connecting structure 524 on the cover 520 to be precisely embedded in the corresponding second clearance groove 420 during assembly, thereby effectively avoiding interference between the second connecting structure 524 and the tooling, and preventing structural deformation or damage caused by collision or compression. Furthermore, this design also helps improve the positioning accuracy of the cover 520 on the tooling, ensuring stable assembly posture and accurate positioning.

[0051] Preferably, in this embodiment, the second clearance groove 420 is rectangular, and the specific shape can be set according to actual needs.

[0052] In this embodiment, the size of the second clearance groove 420 is larger than the size of the second connecting structure 524. This design allows the tooling to be adapted to different models of protective housings 500, since the length or position of the second connecting structure 524 may differ between different models of protective housings 500, thereby effectively improving the versatility and adaptability of the tooling.

[0053] In this embodiment, when the second connecting structure 524 is located within the second clearance groove 420, a third gap 320 exists between the second connecting structure 524 and the bottom wall of the second clearance groove 420. This design prevents the second connecting structure 524 from being squeezed by the tooling during assembly, thereby effectively preventing the second connecting structure 524 from deforming or being damaged due to force, ensuring its structural integrity and the realization of subsequent assembly functions.

[0054] In this embodiment, the mounting groove 110 is further provided with a first limiting surface 111 and a second limiting surface 112 arranged opposite to each other. The first limiting surface 111 and the second limiting surface 112 are perpendicular to the first step 200 and the second step 400, respectively, and the straight-line distance between the first limiting surface 111 and the second limiting surface 112 is adapted to the width of the base 510. This design provides reliable lateral limiting support for the base 510, preventing lateral displacement or shaking during assembly, thereby ensuring the assembly accuracy and consistency between the base 510 and the cover 520.

[0055] Preferably, in this embodiment, the body 100 is made of non-conductive, high-temperature resistant, and high-mechanical-strength phenolic plastic, and the outer surface of the body 100 is also provided with an anti-corrosion coating. This design not only meets the performance requirements of the tooling in the electrical assembly process, such as insulation, temperature resistance, and high strength, but also significantly improves its environmental adaptability and safety in use.
