Description

Technical Field

[0001] The present application relates to the field of traction beam processing equipment, and in particular to a traction beam shaping tooling. Background Art

[0002] The traction beam is an important component of the car body steel structure. During the operation of the car body, the traction beam not only transmits traction and braking force to the coupler, but also bears the loads of various equipment and the horizontal longitudinal and lateral impact loads during traction. The traction beam includes the traction beam body, the stop beam and the buffer beam, and its various parts are welded together. During the welding process, the steel structure around the weld expands due to heat, causing the steel beam structure around the weld to bulge, so the traction beam needs to be adjusted.

[0003] The existing traction beam shaping operation uses a single hydraulic cylinder to squeeze the raised parts around the weld one by one, flattening the raised distribution to complete the shaping of the traction beam. However, this method requires a lot of time to adjust the position of the hydraulic cylinder and fix it each time a raised part is flattened, resulting in low shaping efficiency of the traction beam. Utility Model Content

[0004] In order to improve the problem that when each pair of raised parts is flattened, it takes a lot of time to adjust the position of the hydraulic cylinder and fix it, resulting in low adjustment efficiency of the traction beam, the present application provides a traction beam adjustment tool.

[0005] The present application provides a traction beam shaping tooling that adopts the following technical solution:

[0006] A traction beam shaping tool comprises a tool frame and a support platform for placing the traction beam. The tool frame is provided with a hydraulic cylinder at the position corresponding to the traction beam weld. The hydraulic cylinder faces the support platform so as to be able to flatten the raised part around the weld. A pressure plate is provided on the piston rod of the hydraulic cylinder. The pressure plate is connected to the piston rod of the hydraulic cylinder through an adjustment component. The adjustment component can adjust the pressure plate to the raised position. Each of the hydraulic cylinders is connected to a control valve in the hydraulic system. The control valve can control the hydraulic cylinders to extend or shorten at the same time.

[0007] By adopting the above technical solution, when adjusting the shape of the raised part on the traction beam, the traction beam is first placed on the support platform, and then the position of the pressure plate is adjusted through the adjustment component so that the pressure plate is aligned with the raised part on the traction beam. Then, the hydraulic cylinder is controlled to extend at the same time through the control valve, and the hydraulic cylinder pushes the pressure plate to flatten the raised part to realize the traction beam adjustment operation. The present application can flatten and adjust the raised part on the traction beam once without adjusting the position of the hydraulic cylinder, thereby improving the adjustment efficiency of the traction beam.

[0008] In a specific embodiment, the adjustment assembly includes a circumferential adjustment member and a radial adjustment member. The radial adjustment member is used to adjust the radial position of the pressure plate along the hydraulic cylinder, and the circumferential adjustment member is used to adjust the circumferential position of the pressure plate along the hydraulic cylinder.

[0009] By adopting the above technical solution, the position of the pressure plate is adjusted using the circumferential adjustment member and the radial adjustment member, thereby improving the flexibility of adjusting the position of the pressure plate.

[0010] In a specific possible implementation scheme, the circumferential adjustment member includes an adjusting rod and a rotating disk, the radial adjustment member is arranged on the adjusting rod, the adjusting rod is fixedly arranged on the rotating disk along the radial direction of the hydraulic cylinder, and the rotating disk is rotatably connected to the piston rod of the hydraulic cylinder so that it can rotate along a horizontal plane.

[0011] By adopting the above technical solution, when adjusting the circumferential position of the pressure plate, the operator drives the adjusting rod to rotate together with the rotating disk to achieve the adjustment of the circumferential position of the pressure plate.

[0012] In a specific possible implementation scheme, the radial adjustment member includes a dovetail block arranged on the pressure plate, the adjustment rod is provided with a dovetail groove arranged along its own length direction, the dovetail block and the dovetail groove are matched in a concave-convex manner and are slidably connected.

[0013] By adopting the above technical solution, when adjusting the radial position of the pressure plate, the pressure plate is pushed to slide, and the pressure plate slides along the length direction of the adjustment rod through the cooperation between the dovetail block and the limit groove, thereby realizing the adjustment of the radial position of the pressure plate.

[0014] In a specific possible implementation scheme, the dovetail block is provided with a compression spring, and the compression spring can push the dovetail block to abut against the groove wall of the dovetail groove.

[0015] By adopting the above technical solution, the extrusion spring is used to push the dovetail block to abut against the groove wall of the dovetail groove, thereby improving the stability of the pressure plate after the position is adjusted.

[0016] In a specific feasible implementation scheme, a T-shaped portion is provided on the piston rod of the hydraulic cylinder, and a T-shaped ring groove is provided on the rotating disk for rotatably cooperating with the T-shaped portion, so that the rotating disk is rotatably connected to the piston rod of the hydraulic cylinder, and the depth of the T-shaped ring groove is greater than the thickness of the T-shaped portion, so that there is a gap between the end face of the T-shaped portion and the bottom wall surface of the T-shaped ring groove.

[0017] By adopting the above technical solution, the cooperation between the T-shaped portion and the T-shaped ring groove is utilized to realize the rotational connection between the rotating disk and the piston rod of the hydraulic cylinder; by utilizing the gap between the bottom wall of the T-shaped ring groove and the end face of the T-shaped portion, after the shape is adjusted, the rotating disk is pressed down to separate the T-shaped portion from the rotating disk, thereby avoiding adhesion between the rotating disk and the T-shaped portion due to cold welding.

[0018] In a specific possible implementation scheme, an electromagnet is provided on the piston rod of the hydraulic cylinder, and the electromagnet can adsorb the rotating disk so that the end surface of the T-shaped portion abuts against the bottom wall surface of the T-shaped ring groove.

[0019] By adopting the above technical solution, the electromagnet is used to adsorb the rotating disk, which avoids the hydraulic cylinder sliding between the rotating disk when pressing down and causing the change of the pressure plate position, thereby improving the stability of the pressure plate when pressing down.

[0020] In a specific possible implementation scheme, the adjusting rod extends to both sides of the piston rod of the hydraulic cylinder, and a support tube is slidingly sleeved on the piston rod of the hydraulic cylinder. The support tube is connected to the adjusting rods on both sides of the piston rod of the hydraulic cylinder through two connecting rods.

[0021] By adopting the above technical solution, the adjusting rod is supported by the support tube and the two connecting rods, the eccentric torque applied to the adjusting rod is balanced, and the adjusting rod is effectively prevented from being compressed and bent.

[0022] In summary, this application includes at least one of the following beneficial technical effects:

[0023] 1. When adjusting the shape of the raised portion of the traction beam, first place the traction beam on the support platform, then adjust the position of the pressure plate through the adjustment component so that the pressure plate is aligned with the raised portion of the traction beam, and then control the hydraulic cylinder to extend simultaneously through the control valve. The hydraulic cylinder pushes the pressure plate to flatten the raised portion to achieve the traction beam adjustment operation. This application can flatten and adjust the raised portion of the traction beam in one go without adjusting the position of the hydraulic cylinder, thereby improving the adjustment efficiency of the traction beam.

[0031] The following is combined with Figure 1-4 This application is described in further detail.

[0032] The embodiment of the present application discloses a traction beam shaping tool.

[0033] Reference Figure 1 A traction beam shaping tooling includes a tooling frame 1 and a support platform 2 for placing the traction beam. The support platform 2 is arranged below the tooling frame 1 and is hollowed out to reduce the weight of the support platform 2. The tooling frame 1 is welded by hollow beams and has an I-shaped structure. The tooling frame 1 is provided with hydraulic cylinders 3 at the positions corresponding to the welds of the traction beams. This embodiment takes three hydraulic cylinders 3 as an example. Each hydraulic cylinder 3 is fixed to the inside of the hollow beam of the tooling frame 1 by a mounting plate and bolts, and the piston rod of the hydraulic cylinder 3 is set downward. The position of each hydraulic cylinder 3 on the tooling frame 1 can be adjusted automatically according to the position of the weld on the traction beam.

[0034] A pressure plate 4 is provided on the piston rod of each hydraulic cylinder 3. The pressure plate 4 is connected to the piston rod of the hydraulic cylinder 3 through an adjusting component 5. The adjusting component 5 can adjust the position of the pressure plate 4 in the horizontal plane so that the pressure plate 4 is aligned with the bulge on the traction beam. Each hydraulic cylinder 3 is connected to the control valve 6 in the hydraulic system through a hydraulic pipeline (not shown in the figure). The control valve 6 controls the simultaneous extension or contraction of the hydraulic cylinder 3.

[0035] When adjusting the shape of the raised part on the traction beam, the traction beam is first placed on the support platform 2, and then the position of the pressure plate 4 is adjusted through the adjustment component 5 so that the pressure plate 4 is aligned with the raised part on the traction beam, and then the hydraulic cylinder 3 is controlled to extend at the same time through the control valve 6. The hydraulic cylinder 3 pushes the pressure plate 4 to flatten the raised part to realize the traction beam adjustment operation. The present application can flatten and adjust the raised part on the traction beam once without adjusting the position of the hydraulic cylinder 3, thereby improving the adjustment efficiency of the traction beam.

[0036] Reference Figure 2 、 Figure 3 The adjustment assembly 5 in this embodiment includes a circumferential adjustment member 51 and a radial adjustment member 52 (such as Figure 4 The circumferential adjustment member 51 in this embodiment includes an adjustment rod 511 and a rotating disk 512. The rotating disk 512 is disposed at the end of the piston rod of the hydraulic cylinder 3. The end of the piston rod of the hydraulic cylinder 3 is provided with a T-shaped portion 513. The rotating disk 512 is provided with a T-shaped ring groove 514 that matches the T-shaped portion 513 in a concave-convex manner. The T-shaped portion 513 is inserted into the T-shaped ring groove 514 and rotatably connected, thereby rotatably connecting the rotating disk 512 to the piston rod of the hydraulic cylinder 3. The depth of the T-shaped ring groove 514 is greater than the thickness of the T-shaped portion 513, so that a gap exists between the end surface of the T-shaped portion 513 and the bottom wall of the T-shaped ring groove 514. When the hydraulic cylinder 3 drives the pressure plate 4 to squeeze the traction beam, the T-shaped portion 513 squeezes the bottom wall of the T-shaped ring groove 514. At this time, due to the large extrusion force, cold welding will occur between the T-shaped portion 513 and the bottom wall of the T-shaped ring groove 514. At this time, using the gap between the bottom wall of the T-shaped ring groove 514 and the end face of the T-shaped portion 513, after the traction beam is adjusted, the operator knocks the rotating disk 512 downward to separate the T-shaped portion 513 from the rotating disk 512, thereby avoiding adhesion between the rotating disk 512 and the T-shaped portion 513 due to cold welding.

[0037] Reference Figure 2 、 Figure 3 The piston rod of the hydraulic cylinder 3 is provided with an electromagnet 515 opposite to the rotating disk 512. The electromagnet 515 generates magnetism when the power supply is energized. After the position adjustment of the pressure plate 4 is completed, the electromagnet 515 is energized. The electromagnet 515 absorbs the rotating disk 512, so that the bottom wall of the T-shaped ring groove 514 and the end face of the T-shaped portion 513 avoid sliding between the hydraulic cylinder 3 and the rotating disk 512 when pressing down, which causes the position of the pressure plate 4 to change, thereby improving the stability of the pressure plate 4 when pressing down.

[0038] Reference Figure 2 、 Figure 3The adjusting rod 511 is fixedly mounted on the rotating disk 512 along the radial direction of the piston rod of the hydraulic cylinder 3. Both ends of the adjusting rod 511 extend toward the sides of the hydraulic cylinder 3. A support cylinder 71 is slidably mounted on the piston rod of the hydraulic cylinder 3. Two connecting rods 72 are fixedly mounted on the support cylinder 71. The two connecting rods 72 extend toward the adjusting rod 511 on both sides of the hydraulic cylinder 3 and are fixedly connected to the adjusting rod 511. The support cylinder 71 and the two connecting rods 72 support the adjusting rod 511, balancing the eccentric torque applied to the adjusting rod 511 and effectively preventing the adjusting rod 511 from bending under pressure.

[0039] Reference Figure 2 、 Figure 4 In this embodiment, the radial adjustment member 52 includes a dovetail block 521 mounted on the pressure plate 4. The adjustment rod 511 is provided with a dovetail groove 522 extending along its length. The dovetail block 521 and the dovetail groove 522 are slidably connected. A compression spring 523 is provided on the dovetail block 521. A spring groove 524 is defined on the side of the dovetail block 521 facing the bottom wall of the dovetail groove 522. The compression spring 523 is located within the spring groove 524. One end of the compression spring 523 abuts the bottom wall of the spring groove 524, while the other end abuts and slidably connects to the bottom wall of the dovetail groove 522.

[0040] When adjusting the radial position of the pressure plate 4, the pressure plate 4 is pushed to slide. The pressure plate 4 slides along the length of the adjustment rod 511 through the cooperation between the dovetail block 521 and the limiting groove, thereby adjusting the radial position of the pressure plate 4. The compression spring 523 pushes the dovetail block 521 to abut against the groove wall of the dovetail groove 522, thereby improving the stability of the pressure plate 4 after the position is adjusted.

[0041] The implementation principle of a traction beam shaping tooling in an embodiment of the present application is as follows: when performing shaping operation on the raised part of the traction beam, the traction beam is first placed on the support platform 2, and then the rotating disk 512 is driven to rotate, and the dovetail block 521 is driven to slide in the dovetail groove 522, so that the pressure plate 4 is aligned with the raised part on the traction beam, and then the electromagnet 515 is driven to be energized, and the electromagnet 515 adsorbs the rotating disk 512, and then the hydraulic cylinder 3 is controlled to extend at the same time through the control valve 6, and the hydraulic cylinder 3 pushes the pressure plate 4 to flatten the raised part to realize the traction beam shaping operation. The present application can flatten and shape the raised part on the traction beam once without adjusting the position of the hydraulic cylinder 3, thereby improving the shaping efficiency of the traction beam.

[0042] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
