Description

Technical Field

[0001] The invention relates to the technical field of high-voltage box top covers, in particular to a device for bonding a high-voltage box top cover and a manufacturing method thereof. Background Art

[0002] The statements in this section merely provide background information related to the present invention and do not necessarily constitute prior art.

[0003] The high-voltage box of a railway vehicle is used to place electrical components. The top cover of the high-voltage box is a large-sized and large-curved component. It is necessary to ensure that the entire top cover does not deform during the bonding process and the positioning is accurate to meet the use requirements. However, when conducting air tightness tests on the existing high-voltage box top cover, air leakage is often found between the top cover of the high-voltage box and the locking surface of the box body. The specific reason is that a frame is set around the composite material top cover, and the top cover is edged to enhance its strength. The frame set around the circle is assembled in multiple sections, and the top cover and the frame are assembled by bonding, such as profiles. There is no suitable The tooling accurately positions the profiles of the top cover. During the bonding process between the cover body and the frame, manual measurements are mainly relied on to ensure the distance between the top cover and the frame. The position of the frame is constantly adjusted during the measurement process. Obviously, the problem with this is that the work efficiency is low. Moreover, since the top cover is large and the length of one side exceeds 2 meters, the profiles are not positioned, resulting in uneven joints between the adjacent profiles after the bonding of the surrounding profiles, affecting the flatness and overall dimensions of the top cover, resulting in a butt gap after the top cover and the box body are locked, affecting the air tightness of the high-pressure box.

[0004] Even if a positioning template is set on the profile on site, the positioning template cannot maintain the pressing force on the profile;

[0005] In addition, during the bonding process between the top cover and the profile, glue will flow out, and the overflowed glue will easily lift the top cover, resulting in a deviation in the bonding between the top cover and the profile. In addition, the glue remaining on the surface of the top cover is difficult to handle. Summary of the invention

[0045] As described in the background art, in the prior art, the profiles around the top cover of the high-voltage box are prone to the problem of splicing gaps. In order to solve the above technical problems, the present invention proposes a device for bonding the top cover of the high-voltage box.

[0046] Embodiment 1

[0047] In a typical embodiment of the present invention, a device for bonding a high-voltage box top cover includes a base frame 1, a main body 2 and a peripheral positioning member 3, the base frame 1 has a set height, the base frame 1 supports the main body 2, and from the outside to the inside of the main body 2, the main body 2 is sequentially provided with a first step ring 2-1 and a second step ring 2-2, the height of the first step ring 2-1 is lower than the height of the second step ring 2-2, a positioning groove 2-3 is provided on the side of the second step ring 2-2 close to the first step ring 2-1, and a glue overflow groove 2-4 is provided on the side of the second step ring 2-2 away from the positioning groove, the peripheral positioning member 3 is positioned by the side walls of the first step ring and the second step ring, the peripheral positioning member 3 is arranged higher than the second step ring 2-2, the peripheral positioning member 3 positions the outer side of the top cover frame 4-1 once, the convex portion 4-3 of the top cover frame is inserted into the positioning groove 2-3 to perform secondary positioning on the top cover frame 4-1, and the base frame 2 is connected to the peripheral positioning member 3 to provide a clamping force to the top cover frame 4-1.

[0048] refer to Figure 1 As shown, the base frame 1 is welded with pipe fittings such as square tubes 1-1. The base frame 1 is a hollow skeleton structure. Specifically, carbon steel square tubes can be used. In some examples, 40*40*2.5mm carbon steel square tubes are used for welding. The base frame 1 has a set height. The overall shape of the base frame 1 is consistent with the shape of the high-pressure box cover. The base frame 1 has two surfaces, the two surfaces are arranged parallel to each other, and a distance is set between the two surfaces. The circumferential sides of the two surfaces are connected by welding square tubes, and the four corners of each surface are transitioned by bevels. Each surface is provided with multiple cross structures to ensure the rigidity of the base frame, and a square tube is also connected between the two surfaces along the center line of the length square of the two surfaces.

[0049] It is easy to understand that after the base frame 1 is welded, it is polished as a whole, the weld is beautiful and smooth, and then the primer, mid-coat and topcoat are sprayed for anti-corrosion treatment.

[0050] It should be noted that the main body 2 is placed on the surface of the base frame 1, and the outermost circle size of the main body 2 can be the same as the size of the upper side of the base frame 1. Figure 2 , Figure 3 and Figure 4 As shown, the main body 2 is frame-shaped. From the outside to the inside of the main body 2, the main body 2 is sequentially provided with a first step ring 2-1, a second step ring 2-2, a third step ring 2-5 and an inner frame 2-6. The height of the second step ring 2-2 is higher than the height of the first step ring 2-1, and the height of the second step ring is lower than the height of the third step ring 2-5. The first step ring forms a positioning step ring, a positioning groove is provided on the side of the second step ring close to the first step ring, and a glue overflow groove 2-4 is provided on the side of the second step ring close to the third step ring. Both the positioning groove 2-3 and the glue overflow groove 2-4 are annular. The positioning groove 2-3 is equivalent to machining a downward step on the outer side of the second step ring. An arc segment 2-7 is provided between the third step ring and the inner frame 2-6. The arc segment 2-7 can fit with the inner side of the top cover. The height of the third step ring 2-5 is lower than the height of the inner frame. From the third step ring to the inner frame, the height of the arc segment increases sequentially.

[0051] Therein, grooves are respectively arranged on opposite sides of the main body 2, and the grooves are specifically arranged at the arc-shaped section to accommodate the bosses on the inner side of the top cover body.

[0052] It is easy to understand that the material of the main body 2 can be selected from existing wood substitute materials, such as artificial materials composed of wood fiber, plastic and other additives. The main body can be machined and formed as a whole using an existing engraving machine during processing. It should be noted that because the glue used for bonding the top cover needs to be cured at a temperature of 80°C for two hours, the main body uses high-quality wood substitute with a temperature resistance of 100°C to ensure that the main body does not deform at high temperatures.

[0053] In this embodiment, reference Figure 5 As shown, a peripheral positioning member 3 is provided at the first step circle of the main part, and the clamping member 5 adopts an existing quick clamp. A plurality of clamping members 5 are provided, and a distance is set between two adjacent quick clamps. The quick clamp is installed on the side of the base frame by bolts. One or more quick clamps can be provided on each side of the base frame 1. A slide groove 3-1 is provided on the peripheral positioning member 3, and the clamping bolt of the quick clamp is inserted into the slide groove of the peripheral positioning member. When the quick clamp is locked, the clamping force on the peripheral positioning member and the top cover frame is guaranteed. After the quick clamp is released, it is convenient to take out the top cover.

[0054] Specifically, the peripheral positioning member 3 can select an existing slide groove profile, and the slide groove profile can be arranged in multiple sections. The multiple sections of the slide groove profile are arranged around the first step circle, so that the slide groove protrudes from one side of the second step circle to position the top cover frame 4-1 from the peripheral side, refer to Figure 6As shown, the circumferential positioning member is arranged behind the first step circle and exceeds the second step circle, and the inner sides of the two adjacent sections of the slide groove profile are in contact with each other. Because the first step circle 2-1 has a corner, the outer side of the slide groove profile arranged at the corner may not be in contact with the adjacent slide groove profile, and the two adjacent slide groove profiles are not connected. A slide groove 3-1 is arranged on each side of the slide groove profile.

[0055] It should be noted that the top cover is positioned by the main body 2 and the peripheral positioning member 3. The top cover 4 includes a top cover frame 4-1 and a top cover body 4-2. The top cover body 4-2 is an arc-shaped surface. The top cover frame 4-1 is fixed to the peripheral side of the top cover body. A convex portion 4-3 is arranged at the bottom of the top cover frame. The convex portion falls into the positioning groove on the side of the second step circle. The width of the positioning groove 2-3 is greater than the width of the convex portion 4-3 of the top cover frame. The convex portion is positioned by the inner side wall of the positioning groove. In this way, the top cover frame is positioned in the X direction by the inner side of the peripheral positioning member.

[0056] refer to Figure 7 As shown, the shape of the top cover frame 4-1 is the same as the shape of the second step circle. Because the top cover frame also has a corner, the top cover frame 4-1 also includes multiple sections, and two adjacent sections are sequentially spliced ​​to form a full circle of the top cover frame.

[0057] refer to Figure 8 As shown, the top cover frame 4-1 is a U-shaped top cover frame, the top cover frame 4-1 is hollow and the open side of the top cover frame is arranged toward the center of the main body, that is, the top cover frame has a set thickness, the periphery of the top cover cover body 4-2 is inserted into the open part of the top cover frame 4-1, the inner side of the top cover frame is coated with glue in advance, and the upper and lower sides of the cover body inserted into the top cover frame are bonded by glue, after the top cover frame falls into the positioning groove, the upper side of the top cover frame 4-1 is higher than the upper surface of the peripheral side positioning piece; in addition, the upper side of the top cover frame 4-1 is wider than the bottom side, The upper side of the top cover frame is placed above the third step circle, and the bottom side of the top cover frame 4-1 is located above the overflow glue groove. The bonding around the top cover body is double-sided glue coating, and a large amount of overflow glue will be generated during insertion. Therefore, an overflow glue groove is set on the inner side of the second step circle during the processing of the main body. In other words, an overflow glue groove is left at the joint between the top cover frame and the top cover body to facilitate glue cleaning later. If the overflow glue groove is not opened here, the top cover body will not be able to stick to the arc section of the main body. The overflow glue will lift up the top cover body, resulting in deviation, and the overflow glue after curing will remain on the surface of the product, making it difficult to clean.
