DETAILED DESCRIPTION

[0044] In order to make the objectives, technical solutions and advantages of the present disclosure more clear, the embodiments of the present disclosure will be further described in detail below with reference to the accompanying drawings.

[0045] Figure 1 This is a schematic diagram of the structure of the support rail provided by the embodiment of the present disclosure, combined with Figure 1 The support rail is an important structural member in the guide structure. The support rail includes a support rib 100 and a first guide rail 201 and a second guide rail 202 located on two opposite sides of the support rib 100.

[0046] Figure 2 yes Figure 1 Side view, combined with Figure 2 The support rib 100 is a long member approximately 1 meter long with a curved cross-section. The first guide rail 201 and the second guide rail 202 are slender structural members approximately 1 meter long. The support rib 100 has a first side surface 101 and a second side surface 102 arranged opposite each other. One side of the support rib 100 is bent toward the first side surface 101, forming a bent plate comprising a first connecting plate 1011 and a second connecting plate 1012. An arc-shaped angle is formed between the first connecting plate 1011 and the second connecting plate 1012, and the arc-shaped angle is greater than 90 degrees. The first connecting plate 1011 is the area formed by the bent side of the support rib 100.

[0047] The first guide rail 201 is located inside the angle of the support rib 100 (that is, on the first side 101) and is welded to the first connecting plate 1011. The second guide rail 202 is located outside the angle of the support rib 100 (that is, on the second side 102) and is welded to the second connecting plate 1012. The first and second guide rails 201, 202 are parallel to each other, and their extension directions are parallel to the plate surface on which they are located.

[0048] On the other hand, an embodiment of the present disclosure further provides a method for manufacturing a support rail, which is used to manufacture the above support rail.

[0049] Figure 3 This is a flow chart of the method for manufacturing the support rail provided by the embodiment of the present disclosure, combined with Figure 3 , the preparation method includes:

[0050] S301: Provide a positioning component.

[0051] The positioning assembly has a first guide rail groove, a second guide rail groove and a rib plate groove. The rib plate groove is located between the first guide rail groove and the second guide rail groove. The rib plate groove is connected to the first guide rail groove and the second guide rail groove respectively. The first guide rail groove and the second guide rail groove have the same extension direction.

[0052] Furthermore, the shape of the first guide rail groove is the same as the cross-sectional shape of the first guide rail, the shape of the second guide rail groove is the same as the cross-sectional shape of the second guide rail groove, and the shape of the rib plate groove is the same as the cross-sectional shape of the supporting rib plate.

[0053] S302: Arrange the first guide rail in the first guide rail groove, arrange the supporting rib in the rib groove, and arrange the second guide rail in the second guide rail groove, so that the first guide rail and the second guide rail are respectively located on opposite sides of the supporting rib.

[0054] S303: Adjust the relative positions of the supporting rib, the first guide rail, and the second guide rail, and adjust the positioning assembly so that the first guide rail fits together with the first side surface of the supporting rib, and the second guide rail fits together with the second side surface of the supporting rib.

[0055] S304: Welding the supporting ribs to the first guide rail and the second guide rail respectively.

[0056] When the manufacturing method provided by the embodiment of the present disclosure is used to process the above-mentioned support guide rails, since the manufacturing method first provides a positioning component, and the provided positioning component is respectively provided with a first guide rail groove, a second guide rail groove and a rib plate groove, before the support rib plate, the first guide rail and the second guide rail are welded, the first guide rail groove can be used to limit the first guide rail, the second guide rail can be used to limit the second guide rail groove, and the support rib plate can be used to limit the position of the support rib plate, the first rib plate and the second rib plate. It is also possible to use the positioning component to first position the positions of the support rib plate, the first rib plate and the second rib plate, so that the first guide rail and the second guide rail can be respectively located on the support rib plate The first guide rail is positioned on the first side of the supporting rib plate, and the second guide rail is positioned on the second side of the supporting rib plate. Then, by adjusting the first guide rail, the second guide rail or the positioning assembly, the supporting rib plate is respectively fitted with the first guide rail and the second guide rail, so that during welding, the relative positions of the supporting rib plate, the first guide rail and the second guide rail will not change, so that the supporting guide rail formed after welding has the required structure. Even if there is a large welding stress, the supporting rib plate, the first guide rail and the second guide rail will not cause deformation due to position movement, thereby improving the welding effect and improving the welding accuracy of the support guide rail.

[0057] On the other hand, the embodiment of the present disclosure also provides another method for manufacturing a support rail, such as Figure 4As shown, the production method includes:

[0058] S401: Provide a supporting rib, a first guide rail, and a second guide rail respectively.

[0059] In this embodiment, the supporting ribs can be directly obtained by plasma cutting the steel plate.

[0060] The first guide rail and the second guide rail can also be obtained by directly machining the steel plate.

[0061] S402: Detecting the bending angle, flatness, and straightness of the supporting ribs.

[0062] Step S402 includes:

[0063] 4021: Use the angle detection template to detect the bending angle of the supporting rib.

[0064] In this embodiment, the angle detection template has an outer arc angle, and the angle size and shape of the outer arc angle are the same as the size and shape of the inner fillet angle of the supporting rib.

[0065] During the inspection, the angle detection template is placed on the inner side of the supporting rib, and the outer side surface of the angle detection template is in contact with the first connecting plate and the second connecting plate on the inner side of the supporting rib. Then, the gap between the angle detection template and the first connecting plate and the second connecting plate is detected. If the angle detection template is placed at any position on the inner side of the angle of the supporting rib (that is, the side where the first side is located), the maximum gap between the angle detection template and the first connecting plate and the second connecting plate in the supporting rib is ≤1mm, then the supporting rib is considered qualified.

[0066] To ensure accuracy, inspect at least three locations along the length of the ribs, such as the head, tail, and center. This step is considered acceptable if the maximum gap between the angle inspection template and the first and second connecting plates is ≤1mm.

[0067] Figure 5 This is a schematic diagram of the structure of the angle detection template provided by the embodiment of the present disclosure to detect the support ribs, combined with Figure 5 Optionally, the angle detection template 300 includes a first detection plate 301, a second detection plate 302, and a curved plate 303 connecting the first detection plate 301 and the second detection plate 302. The outer circumference of the curved plate 303 is configured to conform to the arc angle of the inner side of the support rib 100. The first detection plate 301 is configured to conform to the inner side of the first connecting plate 1011 of the support rib 100, and the second detection plate 302 is configured to conform to the inner side of the second connecting plate 1012 of the support rib 100.

[0068] In this way, the bending angle of the supporting rib can be tested through a self-made angle detection template to ensure that the supporting rib meets the processing requirements.

[0069] In addition, in order to facilitate the processing and production of the angle detection template 300, a 3mm thick steel material is designed to be used to make the angle detection template.

[0070] 4022: Check the flatness of the supporting ribs using a plane test sample.

[0071] Figure 6 This is a schematic diagram of the structure of the plane detection template provided by the embodiment of the present disclosure, combined with Figure 6 In this embodiment, the plane inspection template 400 has an inspection inner hole 401 for the support rib to pass through. The shape of the inspection inner hole 401 is the same as the cross-sectional shape of the support rib. The inspection inner hole 401 and the support rib are clearance-matched.

[0072] In the embodiment of the present disclosure, the width dimension of the inner hole 401 (i.e. Figure 6 The dimension in the d direction is the dimension in the cross-sectional thickness direction of the supporting rib plus 1 mm. Figure 6 The length in the middle direction) is the length of the cross section of the supporting rib plus 5mm.

[0073] Figure 7 This is a schematic diagram of the structure of the plane detection sample detection support rib provided by the embodiment of the present disclosure, combined with Figure 7 During the test, the support rib 100 is fixed vertically so that the length direction of the support rib is horizontal. Then, the plane test template 400 is placed outside the support rib 100 and moved along the length direction of the support rib 100.

[0074] If the plane detection template 400 can be moved along one end of the supporting rib 100 to the other end, the flatness of the supporting rib meets the requirements, that is, the flatness detection of the supporting rib is qualified.

[0075] Alternatively, the flat inspection template 400 is made of a 10 mm thick steel plate, with an inspection hole formed in the steel plate in the shape of the cross section of the supporting ribs. The size of the inspection hole meets the aforementioned requirements. Furthermore, after the inspection hole is formed, the surface finish of the inspection hole needs to be tested to ensure that the surface finish of the inspection hole meets 6.3 μm.

[0076] 4023: Use a steel ruler to check the straightness of the supporting rib plate surface.

[0077] Figure 8 This is a schematic diagram of the structure of the steel ruler detection support rib provided by the embodiment of the present disclosure, combined with Figure 8 In the embodiment, a 1-meter steel ruler 500 (the length of the supporting rib is 1 meter) is used to check the straightness of the first connecting plate 1011 and the second connecting plate 1012 in the supporting rib 100. If the straightness is ≤ 0.5 mm, the step is qualified.

[0078] Combining the three data from the above tests, the supporting ribs that meet all three qualification requirements are ultimately parts that meet the product's angle, flatness, and distortion requirements.

[0079] In other examples, the three checks are performed in any order, but must be performed simultaneously. The support ribs can be inspected using the self-designed angle and plane inspection templates described above, along with a common steel ruler. These are reusable, and it takes less than 10 minutes to inspect a single support rib, significantly saving time and the use of specialized equipment like machines. Most importantly, the process is simple, intuitive, and user-friendly.

[0080] The above detection methods have been used for a long time in the manufacture of this structural component. The quality of the supporting ribs is stable and reliable and is in good condition.

[0081] S403: Provide a positioning component.

[0082] The positioning assembly comprises a first guide rail groove, a second guide rail groove, and a rib plate groove. The rib plate groove is located between the first and second guide rail grooves and is connected to the first and second guide rail grooves, respectively. The first and second guide rail grooves extend in the same direction. Furthermore, the shape of the first guide rail groove is identical to the cross-section of the first guide rail, and the shape of the second guide rail groove is identical to the cross-section of the second guide rail groove. The shape of the rib plate groove is identical to the cross-section of the supporting rib plate.

[0083] In this embodiment, the positioning assembly is used to position and assemble the supporting rib plate and the first guide rail and the second guide rail, so that before welding, the first guide rail and the second guide rail of the supporting rib plate can be relatively fixed.

[0084] Figure 9 This is a schematic diagram of the structure of the positioning component provided by the embodiment of the present disclosure, combined with Figure 9 Optionally, in order to further improve the positioning effect of the support ribs, etc., the positioning assembly 600 includes a support seat 61 and a top cover 62, the top cover 62 is connected to the top of the support seat 61, and a rib groove 603 is defined between the bottom surface of the top cover 62 and the top surface of the support seat 61, the first guide rail groove 601 is located in the top of the support seat 61, and the second guide rail groove 602 is located in the bottom of the top cover 62.

[0085] In the above implementation, the support seat 61 is used to support the support rib, and the top cover 62 is used to apply pressure to the support rib so that the first guide rail and the second guide rail can fit tightly together with the support rib.

[0086] Figure 10 yes Figure 9 The exploded diagram of the positioning components, combined with Figure 10 Optionally, the top of the support seat 61 away from the bottom plate 63 has an opening 610 with the same outer contour as the cross section of the support rib. The bottom wall of the opening 610 includes a first bottom wall 6101 and a second bottom wall 6102 connected together and having an angle.

[0087] The top cover 62 has a protrusion 620 on the side facing the support seat 61, and the protrusion 620 is located in the opening 610. A first strip groove 6031 is defined between the protrusion 620 and the first bottom wall 6101, and a second strip groove 6032 is defined between the protrusion 620 and the second bottom wall 6102. The first strip groove 6031 and the second strip groove 6032 are connected to each other and form a rib groove 603. The first strip groove 6031 is used to accommodate the first connecting plate 1011, and the second strip groove 6032 is used to accommodate the second connecting plate 1012.

[0088] In the above implementation, the support seat 61 is provided with an opening 610, so that the support rib can be firmly limited in the top of the support seat 61 through the opening 610 having the same outer contour as the support rib, and the first bottom wall and the second bottom wall of the opening 610 respectively cooperate with the protrusion 620, so that the first connecting plate and the second connecting plate of the support rib can respectively cooperate closely and well with the support seat 61 and the top cover 62, thereby improving the positioning effect.

[0089] Figure 11 yes Figure 9 Side view, combined with Figure 11 Optionally, the positioning assembly 600 further includes a bottom plate 63, the length direction of the bottom plate 63 being the same as the length direction of the supporting rib 100. There are multiple support seats 61, which are arranged at intervals along the length direction of the bottom plate 63 and are located on the same plate surface of the bottom plate 63 and are all connected to the bottom plate 63.

[0090] There are multiple top covers 62, and the multiple top covers 62 are arranged in a one-to-one correspondence with the multiple support seats 61, and each top cover 62 is connected to the top of the corresponding support seat 61. A rib groove 603 is defined between the top cover 62 and the corresponding support seat 61, a first guide rail groove 601 is set in the top of each support seat 61, and a second guide rail groove 602 is set in the bottom of each top cover 62.

[0091] In the above implementation, the base plate 63 serves as a mounting base for the support bases 61, allowing multiple support bases 61 to be arranged at intervals along the length of the support ribs. The multiple support bases 61 can collectively support the support ribs 100 at various locations, maintaining the support ribs 100 in a horizontal position. The top cover 62 is configured to cooperate with the support bases 61, securing them to the corresponding support bases 61 and thereby clamping the support ribs 100 in place.

[0092] In addition, combined Figure 10 To allow each support seat 61 to be arranged along the length of the base plate 63, the bottom of the support seat 61 has two spaced-apart guide holes 604 arranged perpendicular to the base plate 63. Accordingly, two base plates 63 may be provided, with each corresponding to the two guide holes 604 of each support seat 61. Each base plate 63 is positioned within a corresponding guide hole 604 of each support seat 61. The base plate 63 is loosely fitted with the walls of the guide holes 604.

[0093] In other examples, the number of support bases 61 may also be one, for example, the length of the support base 61 is longer, while the length of the support rib is relatively shorter, and the support base 61 is located in the middle of the support rib 100. As long as the support base 61 can support the support rib 100 and the first guide rail 201 and ensure that the support rib and the first guide rail are both horizontal and not bent, the number of support bases 61 can be flexibly set according to the length direction of the support rib and the first guide rail.

[0094] S404: Arrange the first guide rail in the first guide rail groove, arrange the supporting rib in the rib groove, and arrange the second guide rail in the second guide rail groove, so that the first guide rail and the second guide rail are respectively located on opposite sides of the supporting rib.

[0095] When positioning is performed using the positioning assembly, first, the first guide rail is placed in the first guide rail groove on the top of each support seat.

[0096] Figure 12 This is a schematic diagram of the structure where the first guide rail is placed on the support seat, combined with Figure 12 Since the first guide rail and the second guide rail are located on opposite sides of the supporting rib, the first guide rail 201 can be placed in the first guide rail groove 601 of the support seat 61 in a bottom-to-top order.

[0097] Figure 13 yes Figure 12 Side view, combined with Figure 13In addition, since the width of the first guide rail groove 601 is greater than the width of the first guide rail 201, in order to enable the first guide rail 201 to be located in the middle of the first guide rail groove 601, limiting plates 203 (such as 0.5 mm copper plates) can be respectively provided on opposite sides of the width direction of the cross section of the first guide rail 201 so that the first guide rail 201 can be stably placed in the first guide rail groove 601.

[0098] Then, the supporting ribs are placed in the openings on the tops of the respective supporting seats, and the supporting ribs are positioned above the first guide rails.

[0099] Figure 14 This is a structural diagram of the support rib placed on the support seat. Figure 15 yes Figure 14 Side view, combined with Figure 14 and 15 , place the support rib 100 above the first guide rail 201 and in the opening 610 of each support seat 61, so that the support rib 100 can be in close contact with the first guide rail through the gravity of the support rib 100, and the support rib 100 can also be limited by the opening 610.

[0100] Next, each top cover is pressed onto the supporting ribs, and each top cover is arranged corresponding to a supporting seat.

[0101] Figure 16 This is a schematic diagram of the top cover layout. Figure 17 yes Figure 16 Side view, combined with Figure 16 and Figure 17 A corresponding top cover 62 is placed on top of each support seat 61, and bolts are inserted into the top cover 62 and the support seat 61, but not tightened. This also allows the weight of the top cover 62 to exert a certain pressure on the support rib 100, ensuring good contact between the support rib 100 and the first guide rail 201.

[0102] Finally, insert the second guide rail into the second guide rail slot at the bottom of each top cover.

[0103] Figure 18 This is the assembly diagram of the second guide rail, combined with Figure 18 Since the second guide rail groove 602 is located in the top cover 62 , at this time, the second guide rail 202 can be inserted into each top cover 62 to position the second guide rail 202 .

[0104] Similarly, both sides of the second guide rail 202 in the width direction can also be limited by the limiting pieces 203 so that the second guide rail 202 is located in the middle of the second guide rail groove 602 .

[0105] S405: Adjust the relative positions of the supporting rib, the first guide rail, and the second guide rail, and adjust the positioning assembly so that the first guide rail fits together with the first side surface of the supporting rib, and the second guide rail fits together with the second side surface of the supporting rib.

[0106] When making adjustments, you can first adjust the positions of the first guide rail and the second guide rail relative to the support rib along their own length direction, so that the two ends of the length direction of the first guide rail and the second guide rail are aligned with the two ends of the length direction of the support rib.

[0107] Then, the top cover is locked together with the corresponding support seat so that the support ribs are respectively fitted with the first guide rail and the second guide rail.

[0108] The tightness between the top cover and the corresponding support seat can be adjusted by tightening the bolts inserted into the top cover 62 and the support seat 61, so that the first side surface and the second side surface of the support rib are respectively fitted with the first guide rail and the second guide rail.

[0109] S406: Weld the supporting ribs to the first guide rail and the second guide rail respectively.

[0110] Optionally, step S406 includes:

[0111] 4061: Multiple tack welds are performed between the support rib and the first guide rail and the second guide rail, and the multiple tack welds are spaced apart along the length direction of the support rib.

[0112] First, the supporting ribs can be positioned together with the first guide rail and the second guide rail to form a whole through multiple positioning welding, so as to prevent the relative position between them from changing.

[0113] 4062: Weld all the connection parts between the support ribs between two adjacent support seats and the first guide rail and the second guide rail.

[0114] 4063: After the weld cools to room temperature and remains at this temperature for more than 24 hours, remove the positioning assembly 600;

[0115] 4064: Place the support rib, the first guide rail, and the second guide rail on the positioning assembly 600, and ensure that the unwelded portion between the support rib, the first guide rail, and the second guide rail is located between two adjacent support seats;

[0116] 4065: Weld all the connection parts between the support ribs between two adjacent support seats and the first guide rail and the second guide rail.

[0117] During welding, the support base and top cover will obstruct the welds between the support ribs and the first and second guide rails. Therefore, welding can be performed in batches. First, weld the welds not obstructed by the positioning assembly. Then, after cooling and disassembling the positioning assembly, weld the previously obstructed welds. This ensures that all welds are welded completely during the two welding steps.

[0118] S407: Stress relief annealing is performed on the support rib, the first guide rail and the second guide rail after welding.

[0119] Stress relief annealing of welded parts after welding can release the stress of the welding process and reduce deformation.

[0120] The manufacturing method provided by the disclosed embodiments has been used extensively in the manufacture of support rail structures. Post-weld correction of the support rails is no longer necessary, achieving support rib flatness of ≤1mm, rail straightness of ≤1.5mm, and support rail twist of ≤1mm. The finished product is currently of stable and reliable quality and is in excellent use.

[0121] The above description is merely an optional embodiment of the present disclosure and is not intended to limit the present disclosure. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present disclosure shall be included in the scope of protection of the present disclosure.
