Description

Technical Field

[0001] The present application relates to the technical field of rail vehicles, and in particular to a welding tool for a frame of a driver's cab of a rail vehicle. Background Art

[0002] The driver's cab of a rail vehicle is mainly composed of a frame and a roof. During the manufacturing process of rail vehicles, the frame of the driver's cab is welded by the front frame and the car body frame. The front frame and the car body frame are respectively welded by interweaving multiple cross beams and longitudinal beams. The front frame and the car body frame are then placed on a welding tool for welding.

[0003] It needs to be positioned before being fixed on the welding tooling. The existing positioning method is to position it through the threaded holes set on the tooling, and then fix the frame with bolts. However, the staff needs to find the threaded holes one by one, observe the alignment status, and then tighten the bolts one by one to fix them. The positioning process takes a long time, resulting in low efficiency in the welding of the driver's cab frame. Utility Model Content

[0004] In order to improve the problem that the cab frame is positioned and installed using bolts and threaded holes, which takes a long time and leads to low efficiency in cab frame welding, the present application provides a rail vehicle cab frame welding tool.

[0005] The present application provides a rail vehicle cab frame welding tooling that adopts the following technical solution:

[0006] A welding tool for a rail vehicle driver's cab frame comprises a tool frame and fixed legs, wherein the tool frame is provided with a plurality of right-angle positioning plates and support plates, wherein the support plates correspond to the right-angle positioning plates one by one, and the support plates are used to support the right-angle sections formed by the cross beams and the longitudinal beams, wherein the right-angle sections can be fitted with the two right-angle sides of the right-angle positioning plates for positioning, and the tool frame and the fixed legs are both provided with clamping units, wherein the clamping units are used to clamp and fix the cross beams of the vehicle head frame or the vehicle cabin frame to the tool frame or the fixed legs.

[0007] By adopting the above technical scheme, when welding the driver's cab frame, first place the front frame and the cabin frame on the work frame, place the bottom crossbeam of the front frame on the fixed leg, then fit the right-angle section of the frame with the right-angle positioning plate, and then clamp and fix the front frame on the fixed leg and the cabin fixing frame on the tooling frame through the clamping unit, thereby completing the overall positioning and installation of the driver's cab frame. Compared with the bolt installation and positioning method, this scheme has a fast speed in positioning and installing the driver's cab frame, thereby improving the efficiency of driver's cab welding.

[0008] In a specific possible implementation scheme, a rotating seat is fixedly provided on the tooling frame and the fixed leg;

[0009] The clamping unit includes a clamping support rod and a clamping screw. The clamping support rod is rotatably connected to the rotating seat. The clamping support rod is provided with a spiral portion, and the spiral portion can rotate to the top of the beam along with the clamping support rod. The clamping screw passes through the spiral portion and is threadedly connected to the spiral portion. The clamping screw can press and fix the beam on the tooling frame or the fixed leg.

[0010] By adopting the above technical solution, when fixing the crossbeam of the skeleton, the clamping support rod is rotated, and the clamping support rod drives the spiral part to rotate above the crossbeam, and then the clamping screw is rotated, and the clamping screw moves toward the crossbeam and fixes the crossbeam tightly on the tooling frame, so that the fixation and installation of the skeleton is faster.

[0011] In a specific possible implementation scheme, the clamping screw is provided with an adjustment cylinder at one end facing the crossbeam, and an elastic member is provided in the adjustment cylinder. The clamping screw can press and fix the crossbeam through the elastic member, and the clamping support rod is provided with an adjustment member for adjusting the pressure applied by the elastic member to the crossbeam.

[0012] By adopting the above technical solution, when the clamping screw clamps and fixes the crossbeam, the clamping screw drives the adjusting tube to move toward the crossbeam, and then the clamping screw presses the adjusting piece onto the crossbeam to complete the fixation of the frame. By adjusting the elastic force of the elastic piece through the adjusting piece, the clamping screw can effectively avoid squeezing the crossbeam to cause deformation.

[0013] In a specific possible implementation scheme, the elastic member includes an adjustment plate, a telescopic spring, and a pressure plate. The adjustment plate and the pressure plate are both slidably arranged in the adjustment cylinder. The clamping screw is inserted into the adjustment cylinder and is rotatably connected to the adjustment cylinder. The telescopic spring is arranged between the pressure plate and the adjustment plate. The clamping screw can drive the adjustment plate to slide and press the pressure plate against the crossbeam through the telescopic spring.

[0014] By adopting the above technical solution, when the clamping screw moves toward the beam, the pressure plate moves to the beam, and then the clamping screw pushes the adjusting plate to squeeze the telescopic spring to contract, the telescopic spring squeezes the pressure plate, and the pressure plate presses and fixes the beam. The buffer formed by the telescopic spring can effectively avoid the extrusion deformation of the beam and ensure the integrity of the shape of the beam.

[0015] In a specific feasible implementation scheme, the adjusting member includes an adjusting screw and an adjusting block. The adjusting block is slidably arranged on the clamping support rod along the axial direction of the clamping screw. The adjusting screw is rotatably connected to the clamping support rod and is inserted through the adjusting block and is threadedly connected to the adjusting block. The adjusting cylinder is provided with a strip hole arranged along the axial direction of the clamping screw. The adjusting block passes through the strip hole and extends into the adjusting cylinder. The adjusting block is used to limit the movement of the adjusting plate toward the crossbeam.

[0016] By adopting the above technical solution, when adjusting the pressure applied to the crossbeam by the clamping screw, the operator turns the adjusting screw, and the adjusting screw drives the adjusting block to slide along the length direction of the telescopic spring. By adjusting the position of the adjusting block, the compression length of the telescopic spring squeezed by the adjusting plate is adjusted, and then the pressure of the pressure plate on the crossbeam is adjusted. The pressure can be adjusted according to the skeletons of different materials, thereby improving the application range of the device.

[0017] In a specific possible implementation manner, a guide rod is provided on the adjusting cylinder, and the guide rod is slidably connected to the clamping support rod and is used to guide the adjusting cylinder to slide along the axial direction of the clamping screw.

[0018] By adopting the above technical solution, the sliding stability of the adjusting cylinder is improved by guiding the adjusting cylinder by the guide rod.

[0019] In a specific possible implementation mode, a positioning screw is threadedly connected to the tooling frame, and the positioning screw is used to fit and position with the vehicle head frame or the vehicle room frame.

[0020] By adopting the above technical solution, the positioning screw is fitted with the front frame or the vehicle cabin frame, and is positioned in coordination with the right-angle positioning plate, so that the positioning of the frame is more accurate.

[0021] In a specific possible implementation manner, a workbench is provided on the tooling frame.

[0022] By adopting the above technical solution and setting a workbench, it is convenient for workers to perform welding work on the tooling frame.

[0023] In a specific possible implementation mode, the tooling frame is provided with a ladder for guiding the workers to climb onto the workbench.

[0024] By adopting the above technical solution and setting up a ladder, the convenience for workers to climb onto the workbench is improved.

This solution can quickly position and install the cab frame, thereby improving the efficiency of cab welding;

[0027] 2. When the clamping screw moves toward the beam, the pressure plate moves to the beam, and then the clamping screw pushes the adjusting plate to squeeze the telescopic spring to contract. The telescopic spring squeezes the pressure plate, and the pressure plate presses and fixes the beam. The buffer formed by the telescopic spring can effectively avoid the extrusion and deformation of the beam and ensure the integrity of the shape of the beam. By changing the position of the adjusting block, the pressure applied to the beam by the pressure plate is adjusted, so that the pressure can be adjusted according to the skeleton of different materials, thereby improving the adaptability of the device.

[0044] Example 2

[0045] Reference Figure 3 , Figure 4 and Figure 5, The difference between this embodiment and Embodiment 1 is that the clamping support rod 41 in this embodiment is in a U shape. At one end of the clamping screw rod 42 facing the cross beam, an adjusting cylinder 51 is provided. The axis of the adjusting cylinder 51 is collinear with the axis of the clamping screw rod 42. The clamping screw rod 42 is inserted into the adjusting cylinder 51 and is rotatably connected to the adjusting cylinder 51. The end of the adjusting cylinder 51 is inwardly recessed to form a limiting portion, and the end of the clamping screw rod 42 forms a shielding portion. The cooperation between the shielding portion and the limiting portion can limit the separation of the adjusting cylinder 51 and the clamping screw rod 42.

[0046] Refer to Figure 4 , Figure 5 , An elastic member 52 is provided in the adjusting cylinder 51. The elastic member 52 in this embodiment includes an adjusting plate 521, a telescopic spring 522, and a pressing plate 523. Both the adjusting plate 521 and the pressing plate 523 are slidably arranged in the adjusting cylinder 51. The telescopic spring 522 is arranged between the adjusting plate 521 and the pressing plate 523. One end of the telescopic spring 522 is fixedly connected to the adjusting plate 521, and the other end is fixedly connected to the pressing plate 523. A limiting groove 524 is axially opened on the inner side wall of the adjusting cylinder 51. A sliding block 525 for sliding in the limiting groove 524 is provided on the pressing plate 523. Through the cooperation of the limiting groove 524 and the sliding block 525, the pressing plate 523 can slide out of the adjusting cylinder 51, and at the same time, the pressing plate 523 can be prevented from separating from the adjusting cylinder 51. A guiding rod 53 is fixedly provided on the adjusting cylinder 51. The guiding rod 53 is arranged along the axial direction of the clamping screw rod 42. The guiding rod 53 passes through the clamping support rod 41 and is slidably connected to the clamping support rod 41.

[0047] Refer to Figure 4 , Figure 5 , An adjusting member 54 is provided on the clamping support rod 41. The adjusting member 54 in this embodiment includes an adjusting screw rod 541 and an adjusting block 542. The adjusting block 542 is connected to the clamping support rod 41 through a collar 543. The collar 543 is sleeved on the clamping support rod 41 and is slidably connected to the clamping support rod 41. The adjusting screw rod 541 is rotatably connected to the clamping support rod 41 along the axial direction of the clamping screw rod 42 and passes through the adjusting block 542. The adjusting screw rod 541 is threadedly connected to the adjusting block 542. A strip-shaped hole 544 is axially opened on the adjusting cylinder 51. The adjusting block 542 passes through the strip-shaped hole 544 and extends into the adjusting cylinder 51. The end of the adjusting block 542 is located between the adjusting plate 521 and the pressing plate 523.

[0048] The implementation principle of Embodiment 2 is as follows: When the clamping screw rod 42 moves towards the cross beam, the pressing plate 523 moves onto the cross beam. Then, the clamping screw rod 42 pushes the adjusting plate 521 to compress the telescopic spring 522 to contract. The telescopic spring 522 presses the pressing plate 523, and the pressing plate 523 presses and fixes the cross beam. Through the buffer formed by the telescopic spring 522, the extrusion deformation of the cross beam can be effectively avoided, ensuring the integrity of the shape of the cross beam.

[0049] When adjusting the pressure applied to the crossbeam by the clamping screw 42, the operator turns the adjusting screw 541, and the adjusting screw 541 drives the adjusting block 542 to slide along the length direction of the telescopic spring 522. By adjusting the position of the adjusting block 542, the compression length of the telescopic spring 522 squeezed by the adjusting plate 521 is adjusted, and then the pressure of the pressing plate 523 on the crossbeam is adjusted. The pressure can be adjusted according to the skeleton of different materials, thereby improving the application range of the device.

[0050] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto.
