Description

Technical Field

[0001] This application relates to the technical field of rail transit, and particularly to a positioning and welding tooling for a coupler seat. Background Art

[0002] The coupler seat is an important component for connecting train carriages. Its material is cast steel, and the manufacturing process is casting. Subsequent assembly dimension requirements are ensured through machining. The importance of the relative position of the coupler seat to the car body lies in that it directly affects the connection height of the couplers of two cars and the distance between two cars, thus affecting train operation safety. When assembling the coupler seat, welding is required, so a welding tooling is needed to support and position the coupler seat.

[0003] The existing method for fixing the coupler seat: The coupler seat is tightly fixed on the support table by screwing bolts to achieve welding fixation of the coupler seat. However, in this fixing method, the lateral direction of the coupler seat is only restricted by the frictional force applied to the coupler seat by the bolts. When the coupler seat is subjected to a large lateral impact during the welding process, the coupler seat will have a lateral displacement, resulting in poor stability during the welding process of the coupler seat. Utility Model Content

[0004] In order to improve the problem that the coupler seat has a lateral displacement due to a large lateral impact during the welding process, resulting in poor stability during the welding process of the coupler seat, this application provides a positioning and welding tooling for a coupler seat.

[0005] The positioning and welding tooling for a coupler seat provided by this application adopts the following technical solutions:

[0006] A positioning and welding tooling for a coupler seat includes a support table, an end fixing component, and a side fixing component arranged on the support table. The end fixing component is used to tightly fix the end of the coupler seat on the support table;

[0007] The side fixing component includes a fixing block, a fixing member, and a side pressing member. The fixing block is provided with a top pressing part that contacts the top of the edge along the lateral direction of the coupler seat and a side pressing part that contacts the side of the edge. The fixing member is connected to the fixing block to be able to drive the top pressing part to tightly fix on the top of the edge, and the side pressing member is used to press the side pressing part against the side of the edge.

[0008] By adopting the above technical solution, when welding and fixing the coupler seat, first place the coupler seat on the support table, then drive the side pressing part to press against the side surface of the edge along by the side pressing piece, and then press the top pressing part against the top of the edge along by the fixing piece, so that the fixing block presses and fixes the coupler seat on the support table, and then press and fix the end part of the coupler seat on the support table through the end fixing assembly. Due to the restriction of the side pressing part on the edge along, the coupler seat can withstand a large lateral impact, thereby improving the stability during the welding process of the coupler seat.

[0009] In a specific feasible implementation, the fixing piece includes a fixing bolt and a fixing nut. The fixing bolt is fixedly arranged on the support table and can pass through the fixing block. The fixing nut is threadedly sleeved on one end of the fixing bolt passing through the support table to be able to press and fix the fixing block on the support table.

[0010] By adopting the above technical solution, by screwing the fixing bolt to press down the fixing block, the top pressing part is pressed and fixed against the top of the edge along, thereby improving the convenience of pressing and fixing the coupler seat by the fixing block.

[0011] In a specific feasible implementation, the side pressing piece includes a slider and a side pressing bolt. A first strip-shaped hole is opened on the fixing block. The slider is slidably connected in the first strip-shaped hole. The side pressing bolt is threadedly inserted through the fixing block and is rotatably connected to the slider to be able to drive the slider to slide along the first strip-shaped hole.

[0012] By adopting the above technical solution, before the top pressing part presses against the top of the edge along, the operator screws the side pressing bolt. At this time, the fixing block and the slider slide relative to each other, and drive the side pressing part to abut against the side surface of the edge along. With the help of the fixing of the fixing block by the fixing nut, the restriction of the lateral displacement of the coupler seat by the side pressing part is realized; by rotating the side pressing bolt, the fixing block is driven to laterally displace to adjust the position of the side pressing part to adapt to the welding and fixing of coupler seats with different widths.

[0013] In a specific feasible implementation, guiding grooves are opened on the opposite side walls of the first strip-shaped hole along the length direction of itself. The slider is slidably inserted into the guiding grooves.

[0014] By adopting the above technical solution, by using the sliding of the slider in the guiding grooves, the stability of the sliding connection between the slider and the fixing block is improved.

[0015] In a specific feasible implementation, a lateral limiting plate is slidably arranged on the fixing block. An adjusting bolt is rotatably connected to the fixing block. The adjusting bolt passes through the lateral limiting plate and is threadedly connected to the lateral limiting plate to be able to drive the lateral limiting plate to abut against the side wall of the support table.

[0016] By adopting the above technical solution, after the fixing block presses and fixes the coupler seat, rotate the adjusting bolt, and the adjusting bolt drives the lateral limiting plate to abut against the side wall of the support platform. Through the abutment of the lateral limiting plate and the side wall of the support platform, the circumferential fixing stability of the fixing block can be improved.

[0017] In a specific feasible embodiment, the end fixing assembly includes a fixing screw rod, a mounting nut and a mounting block. The fixing screw rod is fixedly arranged on the support platform. The mounting block is sleeved on the fixing screw rod so as to be able to insert into the middle through hole of the coupler seat. The mounting nut is threadedly sleeved on the fixing screw rod so as to be able to press the mounting block against the hole wall of the middle through hole and make the coupler seat press-fitted and fixed on the support platform.

[0018] By adopting the above technical solution, when fixing the end of the coupler seat, rotate the mounting block to insert it into the middle through hole, and then screw the mounting nut to press the mounting block against the hole wall of the middle through hole. At the same time, the mounting block presses and fixes the coupler seat on the support platform, improving the welding stability of the coupler seat.

[0019] In a specific feasible embodiment, the mounting block is provided with a second strip hole for the fixing screw rod to pass through.

[0020] By adopting the above technical solution, by utilizing the sliding of the fixing screw rod in the second strip hole, the length of the mounting block extending out of the fixing screw rod can be adjusted, facilitating the insertion of the mounting block into the middle through hole.

[0021] In a specific feasible embodiment, the support platform is provided with a support frame for placing the mounting block.

[0022] By adopting the above technical solution, the mounting block is supported by the support frame, facilitating the use of the mounting block.

[0023] In summary, the present application includes at least one of the following beneficial technical effects:

[0024] 1. When welding and fixing the coupler seat, first place the coupler seat on the support platform, then drive the side pressing part to abut against the side surface of the edge by the side pressing member, and then press the top pressing part against the top of the edge by the fixing member, so that the fixing block presses and fixes the coupler seat on the support platform. Then, the end of the coupler seat is pressed and fixed on the support platform by the end fixing assembly. Through the restriction of the side pressing part on the edge, the coupler seat can withstand a large lateral impact, thereby improving the stability during the welding process of the coupler seat;

[0025] 2. Before the top pressing part presses against the top of the edge, the operator screws the side pressing bolt. At this time, the fixed block and the sliding block slide relative to each other, and drive the side pressing part to abut against the side of the edge. With the help of the fixing nut to fix the fixed block, the side pressing part restricts the lateral displacement of the coupler seat; by rotating the side pressing bolt, the fixed block is driven to displace laterally, and the position of the side pressing part is adjusted to adapt to the welding fixation of coupler seats with different widths.

Detailed Description of the Embodiment

[0030] The following further Figures 1-3 describes the present application in detail with reference to the attached drawings.

[0031] The embodiment of the present application discloses a coupler seat positioning welding tooling.

[0032] Referring to Figure 1 , a coupler seat positioning welding tooling includes a support table 2 and an end fixing component 3 and a side fixing component 4 arranged on the support table 2. The number of the end fixing components 3 in this embodiment is two, which are respectively located at both ends of the coupler seat 1 to press and fix both ends of the coupler seat 1. The side fixing components 4 are uniformly arranged on both sides of the coupler seat 1.

[0033] Referring to Figure 1 , Figure 2, in this embodiment, the side fixing component 4 includes a fixing block 41, a fixing member 42, and a side pressing member 43. The fixing block 41 is provided with a top pressing portion 411 that contacts the top of the edge 11 on the side of the coupler seat 1 and a side pressing portion 412 that contacts the side of the edge 11. The side pressing portion 412 is perpendicular to the top pressing portion 411. The fixing member 42 is connected to the fixing block 41 to be able to drive the top pressing portion 411 to tightly press and fix on the top of the edge 11, and the side pressing member 43 is used to press the side pressing portion 412 against the side of the edge 11.

[0034] When welding and fixing the coupler seat 1, first place the coupler seat 1 on the support table 2, then drive the side pressing portion 412 to tightly press against the side of the edge 11 through the side pressing member 43, and then press the top pressing portion 411 against the top of the edge 11 through the fixing member 42, so that the fixing block 41 presses and fixes the coupler seat 1 on the support table 2. Then, press and fix the end of the coupler seat 1 on the support table 2 through the end fixing component 3. Due to the restriction of the side pressing portion 412 on the edge 11, the coupler seat 1 can withstand a large lateral impact, thereby improving the stability of the coupler seat 1 during the welding process.

[0035] Refer to Figure 1 、 Figure 2 , in this embodiment, the fixing member 42 includes a fixing bolt 421 and a fixing nut 422. The side pressing member 43 in this embodiment includes a slider 431 and a side pressing bolt 432. The fixing block 41 is provided with a first strip-shaped hole 4311, and guide grooves 4312 are provided on the opposite side walls of the first strip-shaped hole 4311. Both ends of the slider 431 are inserted into the guide grooves 4312 and are slidably connected to the guide grooves 4312 to improve the sliding stability of the slider 431 in the first strip-shaped hole 4311.

[0036] Refer to Figure 1 、 Figure 2 , the fixing bolt 421 is fixedly arranged on the support table 2 along a direction perpendicular to the support table 2. The slider 431 is provided with a through hole for the fixing bolt 421 to pass through, and the fixing bolt 421 is screwed on one end of the fixing bolt 421 passing through the slider 431.

[0037] Refer to Figure 1 、 Figure 2 , the side pressing bolt 432 is threadedly inserted into the fixing block 41 and is arranged along the sliding direction of the slider 431 in the first strip-shaped hole 4311. The end of the side pressing bolt 432 extends into the first strip-shaped hole 4311 and is inserted into the slider 431. The side pressing bolt 432 is rotationally connected through the cooperation of a T-shaped portion and a T-shaped ring groove, so that the side pressing bolt 432 can drive the slider 431 to slide while rotating.

[0038] When fixing the coupler seat 1 with the fixing block 41, the operator screws the side pressure bolt 432. At this time, the fixing block 41 and the sliding block 431 slide relative to each other, and the side pressure part 412 is driven to abut against the side surface of the edge 11. Then the operator screws the fixing nut 422, and the fixing nut 422 presses down the fixing block 41, so that the pressing part 411 is tightly fixed on the top of the edge 11, and the pressing part 411 restricts the top and side of the coupler seat 1 by the side pressure part 412, thereby improving the stability of the fixing block 41 pressing and fixing the coupler seat 1. With the help of the fixing of the fixing block 41 by the fixing nut 422, the lateral displacement of the coupler seat 1 by the side pressure part 412 is restricted; by rotating the side pressure bolt 432, the fixing block 41 is driven to laterally displace, and the position of the side pressure part 412 is adjusted to adapt to the welding fixation of coupler seats 1 with different widths.

[0039] Refer to Figure 1 、 Figure 2 On both sides of the fixing block 41, sliding notches 413 are provided. A lateral limiting plate 414 is slidably provided on the bottom of the fixing block 41. A sliding part 415 that slides in the sliding notch 413 is provided on the lateral limiting plate 414. The sliding part 415 corresponds to the sliding notch 413 one by one. An adjusting bolt 416 is rotatably connected to the fixing block 41. The adjusting bolt 416 is arranged in the sliding notch 413 along the sliding direction of the lateral limiting plate 414. One end of the adjusting bolt 416 is inserted into the fixing block 41 and is rotatably connected to the fixing block 41 through a T-shaped part and a T-shaped ring groove. The adjusting bolt 416 passes through the lateral limiting plate 414 and is threadedly connected to the lateral limiting plate 414. By rotating the adjusting bolt 416, the lateral limiting plate 414 slides along the sliding part 415.

[0040] After the fixing block 41 presses and fixes the coupler seat 1, rotate the adjusting bolt 416. The adjusting bolt 416 drives the lateral limiting plate 414 to abut against the side wall of the support table 2. By the abutment of the lateral limiting plate 414 and the side wall of the support table 2, the circumferential fixing stability of the fixing block 41 can be improved.

[0041] Refer to Figure 2 、 Figure 3, in this embodiment, the end fixing assembly 3 includes a fixing screw rod 31, a mounting nut 32 and a mounting block 33. The fixing screw rod 31 is fixedly arranged on the support table 2 along a direction perpendicular to the support table 2. A second strip-shaped hole 34 is formed in the mounting block 33 along its own length direction. The fixing screw rod 31 is inserted into the second strip-shaped hole 34. By adjusting the length of the mounting block 33 extending out of the fixing screw rod 31, it is convenient for the mounting block 33 to be inserted into the middle through hole 12. The mounting nut 32 is threadedly sleeved on the fixing screw rod 31. When fixing the end of the coupler seat 1, rotate the mounting block 33 and insert it into the middle through hole 12, and then screw the mounting nut 32 to press the mounting block 33 against the hole wall of the middle through hole 12. At the same time, the mounting block 33 presses and fixes the coupler seat 1 on the support table 2, improving the welding stability of the coupler seat 1. A support frame 35 for placing the mounting block 33 is provided on the support table 2. The support frame 35 is used to support the mounting block 33, facilitating the use of the mounting block 33.

[0042] The implementation principle of a coupler seat positioning and welding tooling in an embodiment of this application is as follows: When welding and fixing the coupler seat 1, first place the coupler seat 1 on the support table 2. The operator screws the side pressure bolt 432. At this time, the fixed block 41 and the slider 431 slide relative to each other, and drive the side pressure part 412 to abut against the side surface of the edge 11. Then the operator screws the fixing nut 422. The fixing nut 422 presses down the fixed block 41, so that the top pressure part 411 is tightly pressed and fixed on the top of the edge 11, so that the top pressure part 411 and the side pressure part 412 limit the top and side of the coupler seat 1.

[0043] When fixing the end of the coupler seat 1, rotate the mounting block 33 and insert it into the middle through hole 12, and then screw the mounting nut 32 to press the mounting block 33 against the hole wall of the middle through hole 12. At the same time, the mounting block 33 presses and fixes the coupler seat 1 on the support table 2, improving the welding stability of the coupler seat 1. Through the restriction of the side pressure part 412 on the edge 11, the coupler seat 1 can withstand a large lateral impact, thereby improving the stability during the welding process of the coupler seat 1.

[0044] The above are all the preferred embodiments of this application. The protection scope of this application is not limited by this. Therefore, all equivalent changes made according to the structure, shape and principle of this application should be covered within the protection scope of this application.
