[0048] Now, the exemplary embodiments will be described more fully with reference to the accompanying drawings. However, the exemplary embodiments can be implemented in various forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that the present invention will be thorough and complete, and the concept of the exemplary embodiments will be fully conveyed to those skilled in the art.

[0049] This embodiment provides a locomotive suspension seat assembly tooling for assembling and fabricating the suspension seat. As Figures 1 - 3 shown, the suspension seat includes a bent plate 100, a straight plate 200, and a suspension sleeve 300. The bent plate 100 is provided with a mounting hole 101 for mounting the suspension sleeve 300, and the suspension sleeve 300 is disposed between the bent plate 100 and the straight plate 200. Reinforcing plates 400 are respectively disposed on both sides of the suspension sleeve 300, and the reinforcing plates 400 are disposed between the bent plate 100 and the straight plate 200.

[0050] If manual assembly is used between the bent plate 100, the straight plate 200 and the suspension sleeve 300, the labor intensity of the operator is high, the assembly difficulty is great, the production cycle is long, the production efficiency is relatively low, and the assembly quality is poor. There are frequent rework problems, which increase the production cost.

[0051] To solve this problem, as Figures 4 - 5 shown, the locomotive suspension seat assembly tooling provided in this embodiment includes a workbench 1, a first positioning mechanism 2, a limiting mechanism 3 and a second positioning mechanism 4. The first positioning mechanism 2 is arranged on the workbench 1 and is used to carry the bent plate 100 and position it horizontally. The limiting mechanism 3 is arranged on the workbench 1 and surrounds the first positioning mechanism 2. The limiting mechanism 3 is used to carry the straight plate 200 and position it horizontally. The second positioning mechanism 4 is arranged on the workbench 1 and is configured to respectively abut against and push one end of the bent plate 100 and one end of the straight plate 200, so that the other end of the bent plate 100 and the other end of the straight plate 200 respectively abut against the limiting mechanism 3, and is used for vertical positioning of the bent plate 100 and the straight plate 200.

[0052] For the locomotive suspension seat assembly tooling provided in this embodiment, the first positioning mechanism 2 is used to carry the bent plate 100 and position it horizontally. By using the first positioning mechanism 2, the horizontal section of the bent plate 100 is ensured to be horizontally placed and its flatness is guaranteed. The limiting mechanism 3 is used to carry the straight plate 200 and position it horizontally. By using the limiting mechanism 3, the flatness of the straight plate 200 and the relative position relationship between the straight plate 200 and the bent plate 100 are guaranteed. The second positioning mechanism 4 is configured to respectively abut against and push one end of the bent plate 100 and one end of the straight plate 200, so that the other end of the bent plate 100 and the other end of the straight plate 200 respectively abut against the limiting mechanism 3, ensuring that the other end of the bent plate 100 and the other end of the straight plate 200 are coplanar to meet the requirements of suspension seat assembly. Under the interaction of the first positioning mechanism 2, the limiting mechanism 3 and the second positioning mechanism 4, rapid auxiliary assembly of the suspension seat is carried out, reducing the cumbersome repetitive work in the assembly and welding processes, reducing the production cost, reducing the labor intensity of the operator, saving labor costs, and improving production efficiency. At the same time, this locomotive suspension seat assembly tooling has a simple structure and is easy to operate, reducing the operation difficulty of assembly and improving the production and assembly quality.

[0053] It should be particularly noted that the outer shape of the workbench 1 is a cuboid structure. The length direction of the workbench 1 is defined as the first direction, the width direction of the workbench 1 is defined as the second direction, and the height direction of the workbench 1 is defined as the third direction. The first direction, the second direction and the third direction are perpendicular to each other pairwise. The first direction, the second direction and the third direction only represent spatial directions and have no substantial meaning.

[0054] In one embodiment, the first positioning mechanism 2 includes two parallel and spaced pads 21, and the pads 21 are used to carry the bent plate 100.

[0055] Among them, the backing plate 21 is in a strip structure, and the backing plate 21 extends along the second direction and is symmetrically arranged with respect to the center line of the workbench 1 along the second direction. The two backing plates 21 are arranged on both sides of the workbench 1 along the first direction, and the two backing plates 21 are jointly used to carry the bending plate 100 to ensure the supporting effect on the bending plate 100.

[0056] In one embodiment, the height of the backing plate 21 is equal to the distance difference between the lower end surface of the suspension sleeve 300 and the bottom surface of the bending plate 100.

[0057] If there is no backing plate 21 or the height of the backing plate 21 is relatively small, after the suspension sleeve 300 is installed in the mounting hole 101 of the bending plate 100, the lower end surface of the suspension sleeve 300 along the third direction and the bottom surface of the bending plate 100 will be flush. During the alignment process of the suspension seat, it is required that the suspension sleeve 300 protrudes from the bottom surface of the bending plate 100. Therefore, by setting the height of the backing plate 21 to be equal to the distance difference between the lower end surface of the suspension sleeve 300 and the bottom surface of the bending plate 100, after the installation of the suspension sleeve 300 is completed, the top surfaces of the bending plate 100 and the backing plate 21 are in contact, the bottom surface of the suspension sleeve 300 is in contact with the workbench 1, and the height of the backing plate 21 along the third direction is the height by which the suspension sleeve 300 protrudes from the bottom surface of the bending plate 100.

[0058] In one embodiment, the distance between the side surfaces of the two backing plates 21 away from each other is L0, and the length of the bending plate 100 along the first direction is L, and 2 / 3L ≤ L0 ≤ L. In this way, while ensuring that the two backing plates 21 can carry the bending plate 100, it can also ensure that the bending plate 100 is stable and does not shake on the two backing plates 21, and the reliability is good.

[0059] In one embodiment, as Figures 4 - 5 shown, the limiting mechanism 3 includes a first limiting component 31, a second limiting component 32 and a third limiting component 33. The first limiting component 31 and the second limiting component 32 are respectively arranged on both sides of the workbench 1 along the first direction, and the first positioning mechanism 2 is arranged between the first limiting component 31 and the second limiting component 32. The third limiting component 33 is arranged on one side of the first positioning component along the second direction. The first limiting component 31, the second limiting component 32 and the third limiting component 33 jointly carry the straight plate 200. Along the first direction, the third limiting component 33 and the second positioning mechanism 4 can respectively abut against both sides of the straight plate 200 and both sides of the bending plate 100.

[0060] Among them, the first limiting component 31, the second limiting component 32, and the third limiting component 33 are respectively located on three sides of the first positioning mechanism 2, and the three can jointly carry the straight plate 200 to ensure the supporting effect of the straight plate 200. The second positioning mechanism 4 is abutted against one side of the straight plate 200 and the bent plate 100 along the first direction, so that the other sides of the straight plate 200 and the bent plate 100 along the first direction are both abutted against the third limiting component 33, playing a role in limiting and making the end faces flush.

[0061] In one embodiment, the first limiting component 31 includes two columns 311 arranged along the second direction. One of the columns 311 is correspondingly arranged with the first positioning mechanism 2, and the other column 311 is arranged in a staggered manner with the first positioning mechanism 2. At least one side of the column 311 along the second direction is provided with a cushion block 312, and the cushion block 312 is used for carrying the straight plate 200.

[0062] Among them, the column 311 is vertically arranged on the workbench 1. At least one side of the column 311 along the second direction is provided with a cushion block 312. The column 311 provides an installation position for the cushion block 312, and the cushion block 312 is used for carrying the straight plate 200. One of the two columns 311 is correspondingly arranged with the first positioning mechanism 2, and the other column 311 is arranged in a staggered manner with the first positioning mechanism 2 to increase the support and bearing range of the straight plate 200.

[0063] It should be specifically noted that a cushion block 312 is provided on the rear side of one of the columns 311 along the second direction, and a cushion block 312 is provided on the front side of the other column 311 along the second direction. The cushion blocks 312 both protrude towards the direction of the first positioning mechanism 2 to better receive the straight plate 200.

[0064] In one embodiment, the second limiting component 32 includes two limiting columns 321 arranged along the second direction. One of the limiting columns 321 is correspondingly arranged with the first positioning mechanism 2, and the other limiting column 321 is arranged in a staggered manner with the first positioning mechanism 2. At least one side of the limiting column 321 along the second direction is provided with a limiting block 322, and the limiting block 322 is used for carrying the straight plate 200. The limiting column 321 is provided with a rib plate 323 along the first direction and away from the first positioning mechanism 2.

[0065] Among them, the limit posts 321 are vertically arranged on the workbench 1. Limit blocks 322 are arranged on at least one side of the limit posts 321 along the second direction. The limit posts 321 provide installation positions for the limit blocks 322, and the limit blocks 322 are used to carry the straight plate 200. One of the two limit posts 321 is arranged corresponding to the first positioning mechanism 2, and the other limit post 321 is arranged offset from the first positioning mechanism 2 to increase the support and bearing range for the straight plate 200. Under the action of the second positioning mechanism 4, the limit posts 321 and the limit blocks 322 abut against the straight plate 200. Since the limit posts 321 and the limit blocks 322 require high perpendicularity, by arranging rib plates 323 on the limit posts 321, the strength of the limit posts 321 can be improved and the service life of the limit posts 321 can be extended, thereby reducing the repair rate of the entire locomotive hanger group for the tooling.

[0066] It should be particularly noted that limit blocks 322 are arranged on the front sides of both limit posts 321 along the second direction, and the limit blocks 322 protrude towards the direction of the first positioning mechanism 2 to better receive the straight plate 200.

[0067] In one embodiment, the upright post 311 and the limit post 321 arranged opposite to the first positioning mechanism 2 are coplanar with the center line of the workbench 1 along the second direction.

[0068] It can be understood that along the second direction, the rear sides of the upright post 311 and the limit post 321 arranged opposite to the first positioning mechanism 2 are coplanar and located on the center line of the workbench 1 along the second direction, that is, the upright post 311 and the limit post 321 are approximately located at the middle position along the second direction, and the centering is good.

[0069] It should be particularly noted that the distance between the upright post 311 and the corresponding limit post 321 along the first direction is slightly greater than the length of the bent plate 100 along the first direction, so that the bent plate 100 is located between the upright post 311 and the limit post 321, and at the same time ensure that the cushion block 312 on the upright post 311 and the limit block 322 of the limit post 321 can support the straight plate 200 and can be taken out smoothly after the hanger group pairing is completed.

[0070] In one embodiment, as Figures 4 - 5 shown, the third limit assembly 33 includes three support posts 331 arranged in a row along the first direction. Two of the support posts 331 are vertically arranged on the workbench 1 and are located on both sides of the first positioning mechanism 2 along the first direction. Reinforcing ribs 333 are arranged on the side surfaces of the support posts 331 along the second direction, and support blocks 332 are arranged on at least one side of the support posts 331 along the first direction.

[0071] Among them, among the three support columns 331, one support column 331 is just arranged on the center line of the workbench 1 along the first direction. A support block 332 is arranged on the right side surface of this support column 331 along the first direction. The other two support columns 331 are respectively symmetrically arranged on both sides of the center line of the workbench 1 along the first direction. Support blocks 332 are arranged on the left side surface and the right side surface of the one sides of these two support columns 331 along the first direction and away from each other. The front side surfaces of the three support columns 331 are coplanar along the second direction to ensure the flush effect of the straight plate 200 along the second direction. A reinforcing rib 333 is arranged on the rear side surface of the support column 331 along the second direction, which can improve the strength of the support column 331 and extend the service life of the support column 331, thereby reducing the repair rate of the entire locomotive suspension set for the tooling.

[0072] It should be specifically noted that the distance between the side surfaces of the support blocks 332 corresponding to the other two support columns 331 on the one sides away from each other along the first direction is less than or equal to the distance between the left and right side surfaces of the bending plate 100 along the first direction to provide good limit for the bending plate 100.

[0073] In one embodiment, the side surfaces of the limit column 321 and the support column 331 corresponding to the limit column 321 on the one sides along the first direction and close to each other are coplanar. With this setting, the limit column 321 and the support column 331 can make the right end surface of the straight plate 200 flush along the first direction, achieving a butting effect.

[0074] In one embodiment, the side surfaces of the column 311 and the support column 331 corresponding to the column 311 on the one sides along the first direction and close to each other are coplanar. With this setting, the column 311 and the support column 331 can make the left end surface of the straight plate 200 flush along the first direction, achieving a butting effect.

[0075] In one embodiment, as Figures 4 - 5 shown, the second positioning mechanism 4 includes two positioning components, and the two positioning components are respectively arranged on both sides of the workbench 1 along the second direction.

[0076] Among them, among the two positioning components, one positioning component is close to the front side surface of the third limit component 33 along the second direction, and the other positioning component is close to the rear side surface of the column 311 along the second direction. The two positioning components are jointly used to ensure that the right end surface of the bending plate 100 along the first direction and the right end surface of the straight plate 200 along the first direction are coplanar.

[0077] In one embodiment, as Figures 4 - 5As shown in the figure, the positioning assembly includes a vertical plate 41, a first tightening device 42, and a second tightening device 43. The vertical plate 41 is vertically arranged on the workbench 1. The first tightening device 42 penetrates through the vertical plate 41 along the first direction and abuts against the straight plate 200. The second tightening device 43 is located below the first tightening device 42. The second tightening device 43 penetrates through the vertical plate 41 along the first direction and abuts against the bent plate 100.

[0078] Among them, the vertical plate 41 is arranged at the left edge of the workbench 1 along the first direction. The first tightening device 42 and the second tightening device 43 are arranged vertically on the vertical plate 41. The first tightening device 42 is located above the vertical plate 41. The first tightening device 42 penetrates through the vertical plate 41 along the first direction and abuts against the left end face of the straight plate 200. The second tightening device 43 is located below the vertical plate 41. The second tightening device 43 penetrates through the vertical plate 41 along the first direction and abuts against the left end face of the bent plate 100. The right end face of the vertical plate 41 and the right end face of the bent plate 100 abut against the side face of the support column 331.

[0079] It should be particularly noted that the distance between the horizontal center line of the first tightening device 42 and the lower end face of the vertical plate 41 is equal to the distance between the lower end face of the suspension sleeve 300 and the center line of the left end face of the bent plate 100. The distance between the center line of the first tightening device 42 and the center line of the second tightening device 43 is equal to the distance between the center line of the left end face of the bent plate 100 and the center line of the left end face of the straight plate 200.

[0080] The working process of the locomotive suspension seat assembly tooling provided in this embodiment is as follows:

[0081] First, place the bent part of the bent plate 100 of the suspension seat facing the workbench 1 and place the horizontal section of the bent plate 100 horizontally on two cushion blocks 21.

[0082] Abut the second tightening devices 43 of the two positioning assemblies against the left end face of the bent plate 100 along the first direction, so that the right end face of the bent plate 100 is in contact with the left end face of the limit post 321.

[0083] Then, place the suspension sleeve 300 in the mounting hole 101 of the bent plate 100, and place the two reinforcing plates 400 on both sides of the suspension sleeve 300 along the first direction. The reinforcing plates 400 need to be in contact with the end face of the suspension sleeve 300, the upper end face of the horizontal section of the bent plate 100, and the lower end face of the straight plate 200, and spot-weld the reinforcing plates 400, the bent plate 100, and the suspension sleeve 300 to fix their positions.

[0084] Finally, place the straight plate 200 horizontally on the upper end faces of each spacer block 312, limit block 322 and support block 332. Use the first tightening device 42 of the two positioning components to abut against the left end face of the straight plate 200 along the first direction, so that the right end face of the straight plate 200 along the first direction fits against the left end face of the limit post 321. Then, spot-weld the straight plate 200, suspension sleeve 300 and reinforcement plate 400 to fix their positions, thereby completing the assembly and fitting of the suspension seat.
