Description

Technical Field

[0001] This utility model relates to the field of mechanical tooling and provides a control device for preventing welding deformation of the side roller seat and the bolster beam. Background Technology

[0002] With the increasing demand for rail transit vehicles, manufacturers urgently need fast and efficient welding processes to meet the growing production capacity. Currently, the welding process for the anti-roll bearing and the sleeper beam uses traditional tooling benches and F-type clamps for clamping and fixing. This method has the following drawbacks: First, the welding platform is a tooling bench, which can only weld one set of anti-roll bearing and sleeper beam at a time. Furthermore, different tooling benches are needed for welding the front and back sides, which is not only time-consuming and labor-intensive but also occupies a large area, resulting in inefficient and space-saving practices. Second, the single-point clamping method using F-type clamps cannot create an effective anti-deformation field, making it impossible to effectively control welding deformation. Post-weld adjustments are necessary, and the irregular deformation and high dependence on the skills of the adjustment personnel can easily become bottleneck processes, restricting production efficiency. Utility Model Content

[0027] According to one embodiment of the present invention, the support platform includes:

[0028] A crossbeam, the upper surface of which is provided with a support plate, and the outer sides of the two crossbeams are provided with reinforcing plates;

[0054] like Figures 1 to 3As shown in the figure, the present invention provides a control device for preventing welding deformation of the side roller seat and the bolster beam, including two support platforms 100 and two sets of clamping components 200. The two support platforms 100 are arranged opposite to each other and parallel to each other. The two sets of clamping components 200 are symmetrically arranged on the two support platforms 100 respectively. Each set of clamping components 200 includes two first clamping devices 210 and three second clamping devices 220. The first clamping devices 210 are adapted to apply pressure to the side roller seat 300 and the bolster beam 400 during front welding. The second clamping devices 220 are adapted to apply pressure to the side roller seat 300 and the bolster beam 400 during reverse welding. The two first clamping devices 210 and the three second clamping devices 220 are arranged alternately and sequentially.

[0055] The control device for preventing welding deformation of the anti-side roller seat and the bolster beam in this embodiment mainly consists of a support platform 100 and a clamping assembly 200. The two support platforms 100 are arranged opposite each other and their extension directions are parallel to each other. They are used to provide support for both sides of the anti-side roller seat 300 and the bolster beam 400 for welding work. Each support platform 100 is provided with a set of clamping assemblies 200, and the two sets of clamping assemblies 200 are symmetrically distributed on the support platform 100. Each clamping assembly 200 consists of two first clamping devices 210 and three second clamping devices 220, that is, each support platform 100 integrates five clamping devices. The first clamping devices 210 apply pressure to the anti-side roller seat 300 and the bolster beam 400 during front welding, and the second clamping devices 220 apply pressure to the anti-side roller seat 300 and the bolster beam 400 during reverse welding. Two first clamping devices 210 are spaced apart between the three second clamping devices 220, and the first clamping devices 210 and second clamping devices 220 on the two support platforms 100 are positioned opposite each other.

[0056] The first clamping device 210 and the second clamping device 220 apply pressure to the side roller seat 300 and the bolster beam 400 using a dual-mode clamping strategy in stages. During the front welding, a four-pressure point diagonal layout formed by four first clamping devices 210 on two support platforms 100 is used to form a rhomboid pressure zone that resists torsional stress and applies pressure to the side roller seat 300 and the bolster beam 400. During the reverse welding, a composite anti-deformation system is formed by the longitudinal constraint of the two pressure points formed by three second clamping devices 220 and the diagonal layout of the four pressure points to apply pressure to the side roller seat 300 and the bolster beam 400.

[0057] This utility model's control device for preventing welding deformation of the anti-side roller seat and the bolster beam can meet the production requirements of welding both sides of the workpiece during the assembly welding process of the anti-side roller seat 300 and the bolster beam 400. It adopts an anti-deformation control method formed by combining the back-to-back double-point longitudinal constraint method and the four-pressure point diagonal layout method. Through the regular combination of the clamping components 200, it can offset complex welding deformation problems, effectively reduce the difficulty of assembly welding, eliminate complex post-weld adjustment and repair work, and achieve precise control of welding thermal deformation. It can effectively improve the efficiency of assembling the anti-side roller seat 300 and the bolster beam 400, reduce the labor intensity of the operator, and reduce the high dependence on the skills of the assembly welding and adjustment personnel.

[0058] Compared with traditional welding fixtures, this utility model can reduce welding deformation by 60%-75% and improve the uniformity of residual stress distribution by 40%. It can also adapt to different process requirements of manual welding and automatic welding. One set of equipment can meet the production efficiency requirements of welding one car (one and two ends) at the same time, and can also meet the anti-deformation and maintenance requirements of the anti-roll seat 300 and the bolster beam 400 front and back welding process. The shaping time of a single product is shortened by 3.2 working hours.

[0059] According to one embodiment of the present invention, the three second clamping devices 220 include two corner clamping devices 221 and one intermediate clamping device 222. The intermediate clamping device 222 is located between the two corner clamping devices 221, and the two first clamping devices 210 are respectively located between the intermediate clamping device 222 and the two corner clamping devices 221.

[0060] In this embodiment, two of the three second clamping devices 220 are corner clamping devices 221, and one is a middle clamping device 222. Along the extension direction of the support platform 100, from both ends towards the middle, there are two corner clamping devices 221, two first clamping devices 210, and one middle clamping device 222. During reverse welding, the two middle clamping devices 222 of the two support platforms 100 form a double-pressure point longitudinal constraint, and the four corner clamping devices 221 of the two support platforms 100 form a four-pressure point diagonal layout, thereby forming a composite anti-deformation system to apply pressure to the anti-side roller seat 300 and the bolster beam 400.

[0061] like Figure 4 and Figure 5 As shown, two support platforms 100 are defined as the first support platform 160 and the second support platform 170, respectively. The first support platform 160 is provided with four corner clamps 2211, one first clamp 211, one intermediate clamp 2221, one first clamp 212 and four corner clamps 2212 in sequence. Correspondingly, the second support platform 170 is provided with four corner clamps 2213, one first clamp 213, one intermediate clamp 2222, one first clamp 214 and four corner clamps 2214 in sequence.

[0062] like Figure 6 , Figure 7 and Figure 8 As shown, this utility model can achieve simultaneous front and back welding of two sets of anti-side roller seats 300 and bolster beam 400. During front and back assembly, the combined use of clamping devices enables precise control of welding deformation of the anti-side roller seats 300 and bolster beam 400. While ensuring the strength of the tooling, it minimizes weight and reduces the burden on construction workers. The specific implementation process of the anti-deformation control method of the welding deformation control device for the anti-side roller seats 300 and bolster beam 400, using the "back-to-back double-point longitudinal constraint method + four-pressure-point diagonal layout method," is as follows:

[0063] Frontal anti-deformation mode: The two bolster beams 400 are stored back to back, and then the first clamping device 1 211, the first clamping device 212, the first clamping device 3 213 and the first clamping device 4 214 are used to apply directional pressure to the four corners of the bolster beams 400 to suppress their warping due to heat; the remaining clamping devices are in a relaxed state to facilitate adjustment of the operating space.

[0064] Reverse deformation mode: The two bolster beams 400 are flipped over and stored back to back. The two bolster beams 400 are pressed simultaneously using intermediate clamps 1 2221 and 2222. At the same time, the anti-roll seat 300 is pressed using four corner clamps 1 2211, 2212, 3 2213 and 4 2214 to counteract the welding shrinkage deformation.

[0065] According to one embodiment of the present invention, each first clamping device 210 and second clamping device 220 includes a fixed base 230, a connecting beam 240, a clamping component 250, and a limiting component 260. The fixed base 230 is connected to the support platform 100; the first end of the connecting beam 240 is rotatably connected to the fixed base 230; the clamping component 250 is connected to the second end of the connecting beam 240; and the limiting component 260 is disposed on the fixed base 230 and is adapted to limit the rotation angle of the connecting beam 240.

[0066] In this embodiment, both the first clamping device 210 and the second clamping device 220 consist of a fixed base 230, a connecting beam 240, a clamping component 250, and a limiting component 260. The fixed base 230 is fixed to the support platform 100. The clamping component 250 is connected to the fixed base 230 through the connecting beam 240. The two ends of the connecting beam 240 are a first end and a second end, respectively. The first end is rotatably connected to the fixed base 230, meaning that the relative angle between the connecting beam 240 and the support platform 100 can be adjusted by rotation. The installation of the limiting component 260 on the fixed base 230 restricts the rotation angle of the connecting beam 240, thereby limiting the fixed angle of the connecting beam 240 on the support platform 100. The second end is connected to the clamping assembly 200. After the anti-roll seat 300 and the bolster beam 400 are placed on the support platform 100, the clamping assembly 200 can contact the surfaces of the anti-roll seat 300 and the bolster beam 400 and apply pressure to them.

[0067] According to one embodiment of the present invention, the fixing base 230 includes a base plate 231 and two baffles 232. The base plate 231 is connected to the support platform 100. The two baffles 232 are disposed opposite to each other on the base plate 231, and the two baffles 232 and the base plate 231 form a groove 233. The first end of the connecting beam 240 is inserted into the groove 233, and the connecting beam 240 and the baffles 232 are connected by a rotating shaft 234.

[0068] In this embodiment, the fixing base 230 consists of a base plate 231 and two baffles 232. One side of the base plate 231 is connected to the support platform 100, and two parallel baffles 232 are vertically arranged on the other side. A U-shaped groove 233 is formed between the two baffles 232. The first end of the connecting beam 240 is inserted into the groove 233 and is rotatably connected to the baffles 232 through the rotating shaft 234, thereby changing the angle of the connecting beam 240.

[0069] In other embodiments, the fixing base 230 may also be a structure in which the base plate 231 and the baffle 232 are integrally formed. The first end of the baffle 232 and the connecting beam 240 is provided with a mounting hole for the rotating shaft 234 to be installed. The rotating shaft 234 passes through the mounting hole to rotatably connect the baffle 232 and the connecting beam 240. The connecting beam 240 is an L-shaped bent beam, with the vertical section extending from bottom to top and the lower end connected to the fixing base 230. One end of the horizontal section is connected to the upper end of the vertical section, and the other end extends horizontally above the support platform 100.

[0070] According to one embodiment of the present invention, the baffle 232 is provided with a limiting hole, and the limiting component 260 includes a limiting bolt 261, which is detachably connected to the limiting hole.

[0071] In this embodiment, the limiting component 260 mainly consists of a limiting bolt 261, and the baffle 232 is provided with a limiting hole. After the connecting beam 240 has rotated on the fixed seat 230 to complete the angle adjustment, the limiting bolt 261 can be inserted into the limiting hole to position and fix the connecting beam 240, keeping it in a fixed position. When the connecting beam 240 needs to be adjusted again, the limiting bolt 261 is pulled out of the limiting hole, releasing the connection between the connecting beam 240 and the fixed seat 230. Thus, the opening and closing adjustment of the connecting beam 240 is achieved by using a pluggable limiting bolt 261.

[0072] In other embodiments, the limiting component 260 may also employ other detachable limiting and fixing structures.

[0073] According to one embodiment of the present invention, the second end of the connecting beam 240 is provided with a bushing 241, the bushing 241 is provided with an internal thread, and the pressing component 250 includes a spiral rod 251 and a pressing head 252. The spiral rod 251 passes through the inner side of the bushing 241 and is threadedly connected to the bushing 241. The axial direction of the spiral rod 251 is perpendicular to the support surface of the support platform 100. The pressing head 252 is provided at one end of the spiral rod 251 near the support platform 100.

[0074] In this embodiment, the second end of the connecting beam 240 located on the support platform 100 is provided with a bushing 241 with internal threads. The clamping component 250 mainly consists of a spiral rod 251 and a pressure head 252. The surface of the spiral rod 251 is provided with an external thread that matches the internal thread. The bushing 241 is sleeved on the outside of the spiral rod 251. After the connecting beam 240 is fixed by the limiting bolt 261, the spiral rod 251 is perpendicular to the support surface of the support platform 100. The lower end of the spiral rod 251 is provided with a pressure head 252. Twisting the spiral rod 251 can make the spiral rod 251 rotate inside the bushing 241 and move linearly along its axial direction, thereby adjusting the distance between the pressure head 252 and the support surface.

[0075] When the screw rod 251 rotates in the forward direction, the pressure head 252 moves closer to the support surface until it presses against the surface of the anti-side roller 300 and the bolster beam 400, completing the screw pressing and positioning of the anti-side roller 300 and the bolster beam 400 on the control device. When the screw rod 251 rotates in the reverse direction, the pressure head 252 moves away from the support surface until it leaves the surface of the anti-side roller 300 and the bolster beam 400. The anti-side roller 300 and the bolster beam 400 can then detach from the support table 100, be flipped in the opposite direction, or leave the support table 100 to enter the next process.

[0076] In other embodiments, a handle 254 is provided at the end of the helical rod 251 away from the support platform 100.
