The welding position of the reinforcing ring blank and the support plate is arranged at the arc segment, so that the reinforcing ring blank can be abutted against the hole wall of the inner hole by using the elastic restoring force of the arc segment of the reinforcing ring blank, and false welding is avoided. The above operation is repeated, and the other arc segments are sequentially fixed. Finally, the process allowance of the butt joint ends of the reinforcing ring blank is cut off, and interface butt joint and spot welding are performed, so that the reinforcing ring assembling is completed.

[0003] The end wall support components of the funnel cart require lightweight and high strength; therefore, they are formed by welding plates and columns. Please refer to [link / reference needed]. Figure 1 The diagram illustrates the structure of a commonly used funnel cart end wall support 10, which includes a support plate 11, support columns 12, and reinforcing rings 13 all connected to the support plate 11. The support plate 11 overlaps with one side of the support column 12, and the support plate 11 has one or more inner holes 111, with the reinforcing rings 13 surrounding the inner holes 111.

[0013] In some embodiments, step (5) specifically includes: loosening the pressure member, removing the funnel car end wall support member, and assembling the funnel car end wall support member.

[0014] In a third aspect of this application, an assembly apparatus is provided, applied to the assembly method of the funnel cart end wall support member of the second aspect described above. The assembly apparatus includes: a worktable; a limiting member connected to the worktable, the limiting member limiting the horizontal and vertical positions of the reinforcing ring blank, so that the support plate is located at the middle position of the reinforcing ring blank in the height direction; a first positioning member connected to the worktable, the first positioning member abutting against the periphery of the support column to limit the horizontal position of the support column; a second positioning member connected to the worktable, the second positioning member abutting against the periphery of the support plate to limit the horizontal position of the support plate; a support block connected to the worktable, the support block being disposed below the support plate and abutting against the lower surface of the support plate; and a pressing member connected to the worktable, the pressing member abutting against the upper surface of the support plate to jointly limit the vertical position of the support plate with the support block.

[0015] In some embodiments, the limiting member has a first limiting surface extending in a horizontal direction and a second limiting surface extending in a vertical direction. The first limiting surface is used to support the reinforcing ring blank, and the second limiting surface is in contact with the inner ring surface of the reinforcing ring blank.

[0023] According to one or more embodiments of the present application, the reinforcing ring assembly process first involves bending the substrate to obtain a reinforcing ring blank. The two butt joint ends of the reinforcing ring blank overlap but are not connected, facilitating the release of welding deformation in subsequent welding steps. The reinforcing ring blank is then placed into the inner hole of a support plate, with one arc segment of the reinforcing ring blank pressed against the hole wall and spot-welded for fixation. Setting the welding position between the reinforcing ring blank and the support plate at the arc segment utilizes the elastic restoring force of the arc segment to ensure the reinforcing ring blank presses firmly against the hole wall, preventing incomplete welding.

Detailed Implementation

[0043] To enable those skilled in the art to more clearly understand this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0044] Furthermore, reference numerals and / or reference letters may be repeated in different examples in this application. Such repetition is for simplification and clarity purposes and does not in itself indicate a relationship between the various embodiments and / or settings discussed. In addition, this application provides examples of various specific processes and materials; however, those skilled in the art will recognize the application of other processes and / or the use of other materials.

[0045] Please combine Figure 1 In the relevant technology, the assembly process of the funnel car end wall support 10 is as follows: (1) Making the reinforcing ring 13: the base material is bent into shape and the two ends are welded and fixed to form the reinforcing ring 13. (2) Assembling the reinforcing ring 13: first draw the assembly line 137 on the outside of the reinforcing ring 13, such as Figure 2 As shown, it is then spot-welded to the support plate 11. There are two assembly lines 137, which correspond to the positions of the upper and lower surfaces of the support plate 11 on the reinforcing ring 13 after the reinforcing ring 13 is assembled with the support plate 11. (3) Assembly of support column 12: Draw lines on the support plate 11 to show the installation position of the support column 12, place the support column 12 at the marked line, determine the relative position, and then spot-weld it to the support plate 11.

[0046] The assembly process of the funnel car end wall support in the relevant technology involves first bending and welding the base material into a ring to form a complete reinforcing ring 13, and then spot welding the reinforcing ring 13 to the support plate 11. During spot welding, the reinforcing ring 13 undergoes deformation, resulting in severe local deformation and a large gap between it and the inner hole 111 of the support plate 11. This further leads to poor welding quality in subsequent welding processes. Furthermore, since the reference position for assembling the reinforcing ring 13 and the support plate 11 is the assembly line 137 drawn on the outside of the reinforcing ring 13, it is difficult to draw lines on the outside of the reinforcing ring 13, making it hard to ensure that the assembly line 137 is on the same plane and that the theoretical position of the assembly line 137 (located in the middle of the reinforcing ring 13) is aligned with the support plate 11. On the other hand, aligning the reinforcing ring 13 and the support plate 11 is difficult; even if the assembly line 137 has high positional accuracy, the relative position of the reinforcing ring 13 and the support plate 11 may deviate from the drawn line during alignment. The two reasons mentioned above together result in large dimensional errors and low assembly efficiency of the funnel car end wall support component 10 after assembly.

[0047] The specific technical solutions of this application will be described in detail below with reference to the accompanying drawings, which are not necessarily drawn to scale. Similar or identical reference numerals may be used to designate the same or similar parts in different drawings. The use of similar or identical reference numerals in different drawings does not mean that all drawings including similar or identical reference numerals constitute a single or the same embodiment. The accompanying drawings illustrate the various embodiments discussed in this application in a generalized manner, by way of example and not limitation.

[0048] A first aspect of this application provides a reinforcing ring assembly process for assembling a reinforcing ring 13 into the inner hole 111 of the support plate 11 of the funnel cart end wall support 10. The reinforcing ring assembly process includes the following steps:

[0049] (1) The substrate is bent into shape to obtain the reinforcing ring blank 13a.

[0050] Please see Figure 3 The shape of the reinforcing ring blank 13a obtained in step (1) is the same as the shape of the inner hole 111 of the support plate 11, both including several alternating straight segments 132 and several arc segments 133. Figure 3 Taking the reinforcing ring blank 13a as an example, the reinforcing ring blank 13a is roughly quadrilateral in shape and has four straight line segments 132. Between two adjacent straight line segments 132 are arc segments 133, so the number of arc segments 133 is also four.

[0051] The reinforcing ring blank 13a is generally annular, but its two ends are not connected, and it remains an open structure. The base material is elongated, and its width and thickness are the same as the design width and thickness of the reinforcing ring 13. The length of the base material is greater than the design length of the reinforcing ring 13, thus giving the reinforcing ring blank 13a a process allowance 136. The two mating ends 131 of the reinforcing ring blank 13a overlap.

[0052] Based on the shape of the reinforcing ring blank 13a, the mating end 131 of the reinforcing ring blank 13a can be positioned in the straight segment 132 or the curved segment 133. (See also...) Figure 3 In some embodiments, the mating end 131 of the strong ring blank is located on one of the straight segments 132, which can ensure that the mating ends 131 can fit together relatively tightly after overlapping, which is beneficial to subsequent spot welding and welding operations.

[0053] Please see Figure 3 In some embodiments, the mating end 131 of the reinforcing ring blank 13a is located in the middle of the longest straight segment 132. This position provides ample operating space, facilitating the subsequent step (4) to remove the process allowance 136 and the interface mating.

[0054] (2) Place the reinforcing ring blank 13a into the inner hole 111 of the support plate 11.

[0055] Step (2) is mainly to ensure that the relative positional relationship between the reinforcing ring blank 13a and the support plate 11 meets the design requirements. Specifically, the straight segment 132 and the arc segment 133 of the reinforcing ring blank 13a correspond to the straight segment 132 and the arc segment 133 of the inner hole 111 of the support plate 11, so that each segment of the reinforcing ring blank 13a fits against the hole wall 1111 of the inner hole 111 of the support plate 11. At the same time, in the width direction of the reinforcing ring blank 13a (when assembled, the support plate 11 is placed horizontally, and the width direction of the reinforcing ring blank 13a is the vertical direction, referred to as the Z direction), the support plate 11 is located in the middle of the reinforcing ring blank 13a, that is, the part of the reinforcing ring blank 13a that fits against the hole wall 1111 of the inner hole 111 of the support plate 11 is located in the middle of the reinforcing ring blank 13a.

[0056] Since the reinforcing ring blank 13a is an unclosed structure, when there is a shape error between the reinforcing ring blank 13a and the inner hole 111 of the support plate 11, the reinforcing ring blank 13a can adapt to the shape of the inner hole 111 of the support plate 11, so that the reinforcing ring blank 13a fits the hole wall 1111 of the inner hole 111.

[0057] In some embodiments, step (2) specifically includes: placing the reinforcing ring blank 13a into the inner hole 111 and resting it on the limiting member 22 provided below the support plate 11. The limiting member 22 restricts the horizontal and vertical positions of the reinforcing ring blank 13a so that the reinforcing ring blank 13a fits against the hole wall 1111 of the inner hole 111, and the hole wall 1111 of the inner hole 111 is located at the middle position of the reinforcing ring blank 13a in the height direction.

[0058] Please see Figure 4 , Figure 4 A schematic diagram of the reinforcing ring blank 13a being limited by the limiting member 22 is shown. The limiting member 22 has a first limiting surface 221 extending horizontally and a second limiting surface 222 extending vertically. The first limiting surface 221 supports the reinforcing ring blank 13a, such that the portion of the reinforcing ring blank 13a that fits against the hole wall 1111 of the inner hole 111 of the support plate 11 is located at the exact center of the reinforcing ring blank 13a. The second limiting surface 222 fits against the inner annular surface 135 of the reinforcing ring blank 13a, and applies a force to the reinforcing ring blank 13a toward the hole wall 1111 of the inner hole 111 of the support plate 11, such that the outer annular surface 134 of the reinforcing ring blank 13a fits against the hole wall 1111 of the inner hole 111 of the support plate 11.

[0059] Multiple limiting members 22 can be provided, and the multiple limiting members 22 are arranged at intervals along the circumference of the reinforcing ring blank 13a. The arc segment 133 and the long straight segment 132 of the reinforcing ring blank 13a all need to be provided with limiting members 22. The limiting member 22 can also be an integral structure with multiple first limiting surfaces 221 and multiple second limiting surfaces 222. The specific structure of the limiting member 22 is not limited in this application.

[0060] (3) Press one of the arc segments 133 of the reinforcing ring blank 13a against the wall 1111 of the inner hole 111 and spot weld it in place. Repeat the above operation to fix the other arc segments 133 in sequence.

[0061] The spot welding position between the reinforcing ring blank 13a and the support plate 11 is the arc segment 133 of the reinforcing ring blank 13a. The elastic restoring force of the arc segment 133 of the reinforcing ring blank 13a allows it to press firmly against the wall 1111 of the inner hole 111, preventing incomplete welding. Each arc segment 133 is spot welded sequentially for fixation. Since the two butt joint ends 131 of the reinforcing ring blank 13a are not connected, the welding deformation during spot welding of the arc segments 133 can be gradually released.

[0062] In step (3), when spot welding the reinforcing ring blank 13a to the support plate 11, a pry bar 30 can be used to assist the welding process. Please refer to [link / reference]. Figure 15 and Figure 16The pry bar 30 is inclined relative to the reinforcing ring blank 13a, such that the first actuating arm 31 and the second actuating arm 32 of the pry bar 30 contact the inner ring surface 135 and the outer ring surface 134 of the reinforcing ring blank 13a, respectively. The direction towards the outer ring surface 134 (e.g., ...) Figure 16 (As shown by the rotating arrow a) Rotating the pry bar 30, the first actuating arm 31 and the second actuating arm 32 apply a torque to the reinforcing ring blank 13a. This torque causes the first actuating arm 31 to press against the inner ring surface 135 and apply a force F toward the support plate 11 to the reinforcing ring blank 13a (the direction of the force F is as shown in the figure). Figure 16 As indicated by the straight arrow in the middle, this makes the part of the reinforcing ring blank 13a that contacts the first working arm 31 fit more closely to the wall 1111 of the inner hole 111 of the support plate 11. This is equivalent to forcing the reinforcing ring blank 13a to elastically deform closer to the support plate 11 by means of the pry bar 30, further reducing the gap between the reinforcing ring blank 13a and the wall 1111 of the inner hole 111 of the support plate 11, thereby improving the welding quality.

[0063] (4) Cut off the process allowance 136 of the butt end 131 of the reinforcing ring blank 13a, and perform interface butt welding and spot welding; the reinforcing ring 13 is assembled.

[0064] After the reinforcing ring blank 13a is spot-welded to the support plate 11, the process allowance 136 of the mating end 131 of the reinforcing ring blank 13a is removed. Plasma cutting equipment, laser cutting equipment, etc., can be used to remove the overlapping portion of the mating ends 131 of the reinforcing ring blank 13a, so that the end faces of the two mating ends 131 of the reinforcing ring blank 13a are fitted together and spot-welded for fixation. Figure 5 As shown. Reinforcing ring 13 is now assembled.

[0065] Please see Figure 6 In some embodiments, after removing the process allowance 136 from the mating ends 131 of the reinforcing ring blank 13a, the end faces of the two mating ends 131 of the reinforcing ring blank 13a have a certain gap H, for example, H ≤ 10mm. This ensures that the two mating ends 131 of the reinforcing ring blank 13a can be fixed together by spot welding. By setting this gap H, the thermal deformation caused by welding can be released during the subsequent welding process between the reinforcing ring 13 and the support plate 11. In subsequent welding processes, the gap H will decrease, and the remaining gap can be filled with welding material, allowing the reinforcing ring 13 to form a complete closed-loop structure.

[0066] According to the reinforcing ring assembly process provided in one or more embodiments of this application, the substrate is first bent into shape to obtain a reinforcing ring blank 13a. The two butt joint ends 131 of the reinforcing ring blank 13a are overlapped but not connected, which facilitates the release of welding deformation in subsequent welding steps. Then, the reinforcing ring blank 13a is placed into the inner hole 111 of the support plate 11, and one arc segment 133 of the reinforcing ring blank 13a is pressed against the hole wall 1111 of the inner hole 111 and spot welded for fixation. Setting the welding position of the reinforcing ring blank 13a and the support plate 11 at the arc segment 133 can utilize the elastic restoring force of the arc segment 133 of the reinforcing ring blank 13a to press the reinforcing ring blank 13a against the hole wall 1111 of the inner hole 111, avoiding incomplete welding. The above operation is repeated to fix the other arc segments 133 in sequence. Finally, the process allowance 136 of the butt joint end 131 of the reinforcing ring blank 13a is removed, and the interface is butt-jointed and spot welded, and the reinforcing ring 13 is assembled.

[0067] The reinforcing ring 13 is assembled using the above-described reinforcing ring assembly process. After forming, the reinforcing ring 13 is not butt-welded; instead, a final butt-welding method is adopted, retaining a process allowance 136. This reinforcing ring assembly process avoids assembly inconveniences caused by shape errors between the reinforcing ring 13 and the inner hole 111 of the support plate 11, while also ensuring the assembly gap between the reinforcing ring 13 and the support plate 11. The assembly quality and efficiency of the reinforcing ring 13 are high. The relative position of the reinforcing ring 13 and the inner hole 111 of the support plate 11 meets the design requirements, and the reinforcing ring 13 abuts tightly against the hole wall 1111 of the inner hole 111, resulting in a firm weld and high connection strength.

[0068] Please see Figure 7 , Figure 8 and Figure 9 According to the second aspect of this application, a method for assembling a funnel car end wall support 10 is provided, including the following steps: (1) feeding and fixing the support column 12; (2) feeding and fixing the support plate 11, with the support plate 11 erected above the support column 12; (3) spot welding the support column 12 and the support plate 11; (4) assembling the reinforcing ring 13 according to the reinforcing ring assembly process of the first aspect; (5) the funnel car end wall support 10 is assembled.

[0069] When assembling the funnel car end wall support component 10, the support column 12 is first loaded and positioned. Please refer to [link / reference]. Figure 7 In some embodiments, step (1) specifically includes: placing the support column 12 on the workbench 21 and locking it in the first positioning member 23, the first positioning member 23 restricting the horizontal position of the support column 12. The first positioning member 23 may include a plurality of spaced first positioning blocks 231, the plurality of first positioning blocks 231 being distributed at least on the inner side and end of the support column 12.

[0070] Step (2) specifically includes: placing the support plate 11 on the support column 12 and the support block 25 set on the worktable 21, and locking it in the second positioning member 24, which restricts the horizontal position of the support plate 11. The support plate 11 is pressed by the pressure member 26, and the support column 12, support block 25 and pressure member 26 together restrict the vertical position of the support plate 11.

[0071] Since the reinforcing ring 13 also needs to be installed on the support plate 11, the support column 12 is installed first, followed by the support plate 11. This allows the support plate 11 to be placed on the support column 12, creating a certain gap between the support plate 11 and the worktable 21, providing installation space for the reinforcing ring 13. Please refer to [link / reference]. Figure 8 In some embodiments, the height of the support block 25 is the same as the height of the support column 12, and the support column 12 can work together with the support block 25 to support the support plate 11, thereby reducing the number of support blocks 25.

[0072] Support column 12 and support block 25 support support plate 11 from below, while clamping member 26 presses support plate 11 from above, thereby allowing support column 12, support block 25, and clamping member 26 to jointly restrict the vertical position of support plate 11. In some embodiments, clamping member 26 includes a plurality of spaced-apart clamping devices distributed on the sides of support plate 11 and in the inner hole 111 of support plate 11. The specific structure of the clamping devices can adopt existing clamps, and this application does not limit the specific structure.

[0073] Please see Figure 8 In some embodiments, the second positioning member 24 includes a plurality of spaced-apart second positioning blocks 241. The height of the second positioning blocks 241 is greater than the height of the funnel car end wall support member 10. After the support plate 11 is placed, the ends of the second positioning blocks 241 are higher than the upper surface of the support plate 11. The plurality of second positioning blocks 241 are distributed on the sides of the support plate 11 other than the side connected to the support column 12. The side of the support plate 11 used to connect the support column 12 is not provided with second positioning blocks 241, so as to provide operating space for the spot welding of the support column 12 and the support plate 11 in step (3).

[0074] In some embodiments, step (5) specifically includes: loosening the pressure member 26, taking out the funnel car end wall support member 10, and completing the assembly of the funnel car end wall support member 10.

[0075] According to the assembly method of the funnel cart end wall support 10 provided in one or more embodiments, the product structure is fully utilized for positioning design. The overall height support is based on the support column 12 as the standard. While the support column 12 supports the support plate 11, it also completes the assembly of the support column 12 and the support plate 11, reducing the number of support blocks 25. The reinforcing ring 13 is positioned by the limiting member 22, which not only supports the reinforcing ring 13, but also ensures the relative position of the reinforcing ring 13 and the support plate 11.

[0076] A third aspect of this application provides an assembly apparatus applied to the assembly method of the funnel cart end wall support 10 described in the second aspect. Please refer to... Figure 9 and Figure 10 The assembly device includes a worktable 21, a limiting member 22, a first positioning member 23, a second positioning member 24, a support block 25, and a pressing member 26. The limiting member 22, the first positioning member 23, the second positioning member 24, the support block 25, and the pressing member 26 are respectively connected to the worktable 21, and can be connected by means of snap-fit, fasteners, or magnetic attraction.

[0077] The limiting member 22 restricts the horizontal and vertical positions of the reinforcing ring 13 so that the support plate 11 is positioned at the midpoint of the reinforcing ring 13 in the height direction. See also... Figure 11 In some embodiments, the limiting member 22 is provided with a first limiting surface 221 extending in a horizontal direction and a second limiting surface 222 extending in a vertical direction. See also... Figure 4 The first limiting surface 221 is used to support the reinforcing ring blank 13a, such that the portion of the reinforcing ring blank 13a that fits against the hole wall 1111 of the inner hole 111 of the support plate 11 is located in the exact center of the reinforcing ring blank 13a. The second limiting surface 222 fits against the inner annular surface 135 of the reinforcing ring blank 13a, and the second limiting surface 222 applies a force to the reinforcing ring blank 13a toward the hole wall 1111 of the inner hole 111 of the support plate 11, such that the outer annular surface 134 of the reinforcing ring blank 13a fits against the hole wall 1111 of the inner hole 111 of the support plate 11.

[0078] Multiple limiting members 22 can be provided, and the multiple limiting members 22 are arranged at intervals along the circumference of the reinforcing ring blank 13a. The arc segment 133 and the long straight segment 132 of the reinforcing ring blank 13a all need to be provided with limiting members 22. The limiting member 22 can also be an integral structure with multiple first limiting surfaces 221 and multiple second limiting surfaces 222. The specific structure of the limiting member 22 is not limited in this application.

[0079] Please see Figure 11The diagram shows a schematic of the limiting member 22 in some embodiments. The limiting member 22 has a stepped structure, with the stepped surface serving as the first limiting surface 221 and the vertical surface of the stepped structure serving as the second limiting surface 222. The limiting member 22 can be elongated or curved depending on its position. The elongated limiting member 22 is located on the straight segment 132 of the reinforcing ring blank 13a; the curved limiting member 22 is located on the curved segment 133 of the reinforcing ring blank 13a.

[0080] The first positioning element 23 abuts against the periphery of the support column 12 to limit the horizontal position of the support column 12. (See also...) Figure 8 and Figure 9 In some embodiments, the first positioning member 23 may include a plurality of spaced-apart first positioning blocks 231, which are distributed on the inner side, outer side, and end of the support column 12. In the funnel cart end wall support member 10, the end of the support column 12 along its length is the end; the surface of the support column 12 that is in contact with the support plate 11 is the top surface, and the surface opposite to the top surface is the bottom surface; the remaining two sides are the inner side and the outer side, wherein the inner side is the surface covered by the support plate 11, and the outer side is the surface facing outward. The plurality of first positioning blocks 231 are distributed on the inner side, outer side, and end of the support column 12, and the first positioning blocks 231 abut against the inner side, outer side, and end of the support column 12. The height of the first positioning blocks 231 on the outer side and inner side of the support column 12 is less than the height of the support column 12, so as not to affect the spot welding operation between the support column 12 and the support plate 11.

[0081] In some embodiments, a first positioning block 231 may be provided on the outer side of the support column 12, and two first positioning blocks 231 may be provided on the inner side of the support column 12. The first positioning blocks 231 on the outer and inner sides of the support column 12 are staggered along the length direction of the support column 12 to jointly restrict the horizontal position of the support column 12.

[0082] The second positioning element 24 abuts against the periphery of the support plate 11 to limit the horizontal position of the support plate 11. (See also...) Figure 8 and Figure 9 In some embodiments, the second positioning member 24 includes a plurality of spaced-apart second positioning blocks 241. The height of the second positioning blocks 241 is greater than the height of the funnel car end wall support member 10. After the support plate 11 is placed, the ends of the second positioning blocks 241 are higher than the upper surface of the support plate 11. The plurality of second positioning blocks 241 are distributed on the sides of the support plate 11 other than the side connected to the support column 12. The side of the support plate 11 used to connect the support column 12 is not provided with second positioning blocks 241, providing operating space for spot welding of the support column 12 and the support plate 11.

[0083] In some embodiments, the height of the first positioning block 231 distributed at the end of the support column 12 is greater than the height of the funnel car end wall support member 10. That is, the first positioning block 231 abuts against both the support column 12 and the support plate 11. In this case, the first positioning block 231 can also serve as the second positioning block 241.

[0084] The support block 25 is located below the support plate 11 and abuts against the lower surface of the support plate 11. (See also...) Figure 8 , Figure 9 and Figure 10 In some embodiments, the height of the support block 25 is the same as the height of the support column 12. The support column 12 can cooperate with the support block 25 to jointly support the support plate 11, and the support column 12 acts as the support block 25, thereby reducing the number of support blocks 25. The height of the support block 25 and the height of the support column 12 are greater than half the width of the reinforcing ring 13. When the support plate 11 is placed on the support column 12 and the support block 25, there is sufficient clearance between the support plate 11 and the worktable 21, providing installation space for the reinforcing ring 13.

[0085] The clamping member 26 abuts against the upper surface of the support plate 11 to jointly restrict the vertical position of the support plate 11 with the support block 25. The support column 12 and the support block 25 support the support plate 11 from below, and the clamping member 26 presses the support plate 11 from above, thereby allowing the support column 12, support block 25, and clamping member 26 to jointly restrict the vertical position of the support plate 11. In some embodiments, the clamping member 26 includes a plurality of spaced-apart clamping devices distributed on the sides of the support plate 11 and in the inner hole 111 of the support plate 11. The specific structure of the clamping devices can adopt the fixtures in the prior art, and the specific structure is not limited in this application. The position of the clamping devices is offset from the spot welding position of the support plate 11 and the support column 12, and the spot welding position of the support plate 11 and the reinforcing ring 13, to avoid the clamping devices interfering with the spot welding operation.

[0086] In some embodiments, the clamping member 26 is a flip-type clamping device 26a, a rotary arm type screw clamping device 26b, or a quick-clamping device 26c. See also... Figure 12 The diagram shows a schematic of the structure of a flip-type clamping device 26a in some embodiments. The flip-type clamping device 26a has a handle 261a and a clamping part 262a. The handle 261a drives the clamping part 262a to flip. When the handle 261a rotates toward the support plate 11, the clamping part 262a rotates downward and presses against the support plate 11.

[0087] Please see Figure 13The diagram shows a schematic of the rotary arm type screw clamping device 26b in some embodiments. The rotary arm type screw clamping device 26b includes a rotary arm 261b and a pressure rod 262b that is threadedly engaged with the rotary arm 261b. When it is necessary to clamp the support plate 11, the rotary arm 261b rotates above the support plate 11, and the pressure rod 262b is screwed downwards to tighten it, so that the pressure rod 262b presses the support plate 11. When the pressure rod 262b is loosened and there is a certain gap between it and the support plate 11, it can be rotated to the outside of the support plate 11 without interfering with the picking and placing of the support plate 11.

[0088] Please see Figure 14 The diagram shows a schematic of the quick-clamping device 26c in some embodiments. The quick-clamping device 26c has a built-in spring 263c and includes a bracket 261c, a clamping arm 262c, and a spring 263c. The pressure rod 262b is movably connected to the bracket 261c. The two ends of the spring 263c act on the clamping arm 262c and the bracket 261c, respectively. When the clamping arm 262c is pulled upward, the clamping arm 262c acts on the spring 263c, causing the spring 263c to undergo elastic deformation (being stretched or compressed). When the clamping arm 262c is released, the clamping arm 262c presses against the support plate 11 under the elastic force of the spring 263c.

[0089] The clamping component 26 clamps the support plate 11, facilitating demolding after product assembly and improving production efficiency.

[0090] Please see Figure 15 In some embodiments, the assembly device further includes a pry bar 30. The pry bar 30 is F-shaped and includes a first actuating arm 31 and a second actuating arm 32 arranged in parallel. The first actuating arm 31 contacts the inner annular surface 135 of the reinforcing ring blank 13a, and the second actuating arm 32 contacts the outer annular surface 134 of the reinforcing ring blank 13a, wherein the first actuating arm 31 is close to the welding point between the reinforcing ring blank 13a and the support plate 11.

[0091] Please see Figure 16 When the reinforcing ring blank 13a is spot-welded to the support plate 11, the pry bar 30 is inclined relative to the reinforcing ring blank 13a, so that the first actuating arm 31 and the second actuating arm 32 of the pry bar 30 contact the inner ring surface 135 and the outer ring surface 134 of the reinforcing ring blank 13a, respectively. The direction towards the outer ring surface 134 (e.g., ...) Figure 16 (As shown by the rotating arrow a) Rotating the pry bar 30, the first actuating arm 31 and the second actuating arm 32 apply a torque to the reinforcing ring blank 13a. This torque causes the first actuating arm 31 to press against the inner ring surface 135 and apply a force F toward the support plate 11 to the reinforcing ring blank 13a (the direction of the force F is as shown in the figure). Figure 16As indicated by the straight arrow in the middle, this makes the part of the reinforcing ring blank 13a that contacts the first working arm 31 fit more closely to the wall 1111 of the inner hole 111 of the support plate 11. This is equivalent to forcing the reinforcing ring blank 13a to elastically deform closer to the support plate 11 by means of the pry bar 30, further reducing the gap between the reinforcing ring blank 13a and the wall 1111 of the inner hole 111 of the support plate 11, thereby improving the welding quality.
