Description

Technical Field

[0001] This application belongs to the field of railway vehicle technology, specifically relating to a clamping device. Background Technology

[0002] The center beam is a major load-bearing component of the railway freight car underframe, serving to bear and transmit forces. During welding of the center beam, an air bladder is installed beneath it, with flux placed between the beam and the bladder. The air bladder is inflated to apply pressure to the center beam, while a clamping device simultaneously holds the beam in place, ensuring the air bladder can press the flux firmly onto the beam, thus guaranteeing the smooth progress of the welding process.

[0003] In related technologies, clamping devices are difficult to adapt to different models of center beams. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model provides a clamping device, which aims to at least partially solve the technical problem that the clamping device is difficult to adapt to different models of center beams.

[0005] The technical solution of this utility model is as follows: A clamping device for clamping a central beam, the central beam comprising a body and two wing plates, the two wing plates being connected at an angle to both sides of the body. The clamping device includes: a base; two clamping assemblies spaced apart from the base, the body being located between the two clamping assemblies; each clamping assembly includes: a mounting base, a clamping member, a pushing member, and multiple clamps, the mounting base being disposed on the base, the clamping member being rotatably disposed on the mounting base, one end of the pushing member being rotatably connected to the clamping member, and the other end being rotatably connected to the base, one of the multiple clamps being detachably connected to the clamping member, the wing plates being located between the clamps and the mounting base; wherein the multiple clamps have different thicknesses.

[0006] In some embodiments, when the chuck abuts against the wing plate, the projection of the chuck onto the base at least partially overlaps with the projection of the mounting base onto the base along the height direction of the mounting seat.

[0007] In some embodiments, the end of the mounting base opposite to the body has a receiving groove, and the clamping member is rotatably disposed in the receiving groove.

[0008] In some embodiments, the clamping member includes: a clamping portion detachably connected to the chuck; a first connecting portion connected to the clamping portion; a second connecting portion connected at an angle to the first connecting portion and rotatably connected to the mounting base; and a third connecting portion connected at an angle to the second connecting portion and rotatably connected to the pusher.

[0009] In some embodiments, the clamping part includes: a mounting part connected at an angle to the first connecting part; and a fourth connecting part fixedly connected to the mounting part and detachably connected to the chuck.

[0010] In some embodiments, the end face of the fourth connecting part opposite to the mounting part and the clamp have an embedding groove on one side and an embedding member on the other side, the embedding member being embedded in the embedding groove.

[0011] In some embodiments, the insert includes a dovetail slider, and the insert groove includes a dovetail groove.

[0012] In some embodiments, the clamping assembly further includes a pad disposed on the mounting base; wherein the wing plate is located between the pad and the clamp.

[0013] In some embodiments, the clamping device further includes: a first support member disposed on the base for supporting the body; wherein two clamping components are spaced apart from the first support member.

[0014] In some embodiments, the clamping assembly further includes: a second support member disposed on the first support member and connected to the mounting base; wherein the body is disposed on the second support member.

[0015] The beneficial effects of this utility model include at least the following: Since the two clamping components are spaced apart on the base, the main body is located between the two clamping components, and the mounting base is located on the base, the mounting base can support the mounting base. Because the clamping component is rotatably mounted on the mounting base, one end of the pusher is rotatably connected to the clamping component, and the other end is rotatably connected to the base. One of the multiple chucks is detachably connected to the clamping component. The wing plate is located between the chuck and the mounting base. Therefore, before clamping the wing plate, one of the multiple chucks is mounted on the clamping component. The pusher drives the clamping component to rotate on the mounting base, and the clamping component drives the chuck to move away from the top of the mounting base, increasing the distance between the chuck and the top of the mounting base so that the chuck will not obstruct the center beam, facilitating the placement of the center beam. When placing the center beam, the body is placed on the base between the two clamping components. At the same time, the wing plate is placed on the top of the mounting base. Then, the pusher drives the clamping component to rotate on the mounting base, and the clamping component drives the chuck to move closer to the top of the mounting base, until the chuck abuts against the wing plate, clamping the wing plate to the top of the mounting base, facilitating subsequent welding work.

[0016] Because the multiple clamps have different thicknesses, clamps of different thicknesses can be selected according to the model of the center beam (i.e., the thickness of the flange). For example, when clamping the first center beam, the first clamp that matches the first center beam can be selected from among the multiple clamps and installed on the clamping device to clamp the first center beam. When clamping the second center beam, the first clamp is removed from the clamping device, the second clamp that matches the second center beam is selected from among the multiple clamps and installed on the clamping device to clamp the second center beam. This method can be adapted to different models of center beams, ensuring the stability of clamping the center beam. It eliminates the need to prepare different clamping devices for each model of center beam, thus reducing costs. Attached Figure Description

[0024] This application is described below with reference to the accompanying drawings and specific embodiments: The clamping device provided in this embodiment is intended to at least partially solve the technical problem that clamping devices are difficult to adapt to different models of center beams.

[0025] Combination Figure 1 This application embodiment describes a clamping device for clamping a central beam 10. The central beam 10 includes a body 11 and two wing plates 12. The two wing plates 12 are connected to both sides of the body 11 at an angle. The clamping device includes a base 20 and two clamping assemblies 30. The two clamping assemblies 30 are spaced apart on the base 20, and the body 11 is located between the two clamping assemblies 30. Each clamping assembly 30 includes a mounting base 31, a clamping member 32, a pushing member 33, and multiple clamps 34. The mounting base 31 is located on the base 20. The clamping member 32 is rotatably mounted on the mounting base 31. One end of the pushing member 33 is rotatably connected to the clamping member 32, and the other end is rotatably connected to the base 20. One of the multiple clamps 34 is detachably connected to the clamping member 32. The wing plates 12 are located between the clamps 34 and the mounting base 31. The multiple clamps 34 have different thicknesses.

[0026] The clamping member 32 is hinged to the mounting base 31.

[0027] The pusher 33 can be one of an electric push rod, a pneumatic cylinder, or a hydraulic cylinder.

[0028] When the pusher 33 is a hydraulic cylinder, the hydraulic cylinder includes a cylinder body, a piston, and a push rod. The piston is slidably disposed within the cylinder body, the push rod is connected to the piston, the cylinder body is rotatably connected to the base 20, and the push rod is rotatably connected to the clamping member 32. For example, the cylinder body is hinged to the base 20, and the push rod is hinged to the clamping member 32.

[0029] Since the two clamping components 30 are spaced apart on the base 20, and the body 11 is located between the two clamping components 30, and the mounting base 31 is located on the base 20, the mounting base 31 can be supported by the base 20. Since the clamping member 32 is rotatably mounted on the mounting base 31, one end of the pushing member 33 is rotatably connected to the clamping member 32, and the other end is rotatably connected to the base 20. One of the multiple clamps 34 is detachably connected to the clamping member 32. The wing plate 12 is located between the clamp 34 and the mounting base 31. Therefore, before clamping the wing plate 12, one of the multiple clamps 34 is mounted on the clamping member 32. The pushing member 33 drives the clamping member 32 to rotate on the mounting base 31, and the clamping member 32 drives the clamp 34 to move away from the top of the mounting base 31, so that the clamp 34 is away from the top of the mounting base 31, increasing the distance between the clamp 34 and the mounting base 31. The distance between the tops of the seats 31 ensures that the chuck 34 does not obstruct the center beam 10, facilitating its placement. When placing the center beam 10, the body 11 is placed on the base 20 between the two clamping components 30. Simultaneously, the wing plate 12 is placed on top of the mounting seat 31. Then, the pusher 33 drives the clamping component 32 to rotate on the mounting seat 31. The clamping component 32 drives the chuck 34 to move towards the top of the mounting seat 31, so that the chuck 34 approaches the top of the mounting seat 31 until the chuck 34 abuts against the wing plate 12, clamping the wing plate 12 onto the top of the mounting seat 31 to facilitate subsequent welding work.

[0030] Since the multiple clamps 34 have different thicknesses, clamps 34 of different thicknesses can be selected according to the model of the middle beam 10 (i.e., the thickness of the wing plate 12). For example, when clamping the first middle beam 10, the first clamp among the multiple clamps 34 that is compatible with the first middle beam 10 can be selected and installed on the clamping member 32 to achieve clamping of the first middle beam 10. When clamping the second middle beam 10, the first clamp is removed from the clamping member 32, the second clamp among the multiple clamps 34 that is compatible with the second middle beam 10 is selected, and the second clamp is installed on the clamping member 32 to achieve clamping of the second middle beam 10. This method can be adapted to different models of middle beams 10, ensuring the stability of clamping the middle beam 10. It eliminates the need to prepare different clamping devices for each model of middle beam 10, thus reducing costs.

[0031] In some embodiments, in order to ensure the stability of the chuck 34 in clamping the wing plate 12, when the chuck 34 abuts against the wing plate 12, the projection of the chuck 34 on the base 20 along the height direction of the mounting base 31 overlaps at least partially with the projection of the mounting base 31 on the base 20. When the chuck 34 contacts the wing plate 12, the overlapping projection design makes the force point of the chuck 34 and the support surface of the mounting base 31 form a mechanical coupling in the vertical direction. By increasing the support area in the vertical direction, the clamping force is effectively dispersed, and the lateral moment caused by the eccentric force of the wing plate 12 is reduced, thereby reducing the risk of the chuck 34 tilting or slipping during the clamping process.

[0032] It is understandable that after the wing plate 12 is placed on top of the mounting base 31, and simultaneously, before the pusher 33 drives the clamping member 32 to rotate on the mounting base 31 and the clamping member 32 drives the chuck 34 to move towards the top of the mounting base 31, the projection of the chuck 34 on the base 20 is offset from the projection of the mounting base 31 on the base 20 along the height direction of the mounting base 31. During the process of placing the wing plate 12 on top of the mounting base 31, the chuck 34 will not obstruct the center beam 10, so as to facilitate the placement of the center beam 10.

[0033] Combination Figure 1 In some embodiments, in order to save space, the end of the mounting base 31 away from the main body 11 is provided with a receiving groove 311, and the clamping member 32 is rotatably disposed in the receiving groove 311. By accommodating the clamping member 32 in the receiving groove 311, the idle space inside the mounting base 31 can be fully utilized.

[0034] Combination Figure 1 In some embodiments, to achieve the clamping of the wing plate 12, the clamping member 32 includes: a clamping portion 321, a first connecting portion 322, a second connecting portion 323, and a third connecting portion 324. The clamping portion 321 is detachably connected to the chuck 34. The first connecting portion 322 is connected to the clamping portion 321. The second connecting portion 323 is connected to the first connecting portion 322 at an angle and is rotatably connected to the mounting base 31. The third connecting portion 324 is connected to the second connecting portion 323 at an angle and is rotatably connected to the pusher 33.

[0035] Before clamping the wing plate 12, one of the multiple clamps 34 is installed on the clamping member 32. The pusher 33 is activated. The pusher 33 drives the second connecting part 323 to rotate within the mounting base 31 through the third connecting part 324. The second connecting part 323 drives the first connecting part 322 to move. The first connecting part 322 drives the clamp 34 to move away from the top of the mounting base 31 through the clamping part 321, so that the clamp 34 is away from the top of the mounting base 31, increasing the distance between the clamp 34 and the top of the mounting base 31, so that the clamp 34 will not block the center beam 10, so as to facilitate the placement of the center beam 10. When placing the center beam 10, the body 11 is placed on the base 20 and positioned between the two clamping assemblies 30. At the same time, the wing plate 12 is placed on top of the mounting base 31. Then, the pusher 33 is activated. The pusher 33 drives the second connecting part 323 to rotate within the mounting base 31 via the third connecting part 324. The second connecting part 323 drives the first connecting part 322 to move. The first connecting part 322 drives the chuck 34 to move towards the top of the mounting base 31 via the clamping part 321, so that the chuck 34 approaches the top of the mounting base 31 until the chuck 34 abuts against the wing plate 12, clamping the wing plate 12 to the top of the mounting base 31 to facilitate subsequent welding work.

[0036] For example, the second connecting portion 323 has a first end and a second end disposed opposite to each other, the two opposite sides of the first end are respectively connected to the first connecting portion 322 and the second connecting portion 323, and the second end is rotatably connected to the mounting base 31.

[0037] In some embodiments, the included angle between the second connecting portion 323 and the first connecting portion 322 can be set to 45° to 135°. In this embodiment, the included angle between the second connecting portion 323 and the first connecting portion 322 is 90°, that is, the first connecting portion 322 is perpendicular to the clamping portion 321. This is only used as an example and should not be construed as a limitation of this application.

[0038] In some embodiments, the included angle between the third connecting portion 324 and the second connecting portion 323 can be set to 45° to 135°. In this embodiment, the included angle between the first connecting portion 322 and the clamping portion 321 is 90°, that is, the third connecting portion 324 and the second connecting portion 323 are set perpendicularly, which is not to be construed as a limitation of this application.

[0039] Combination Figure 1In some embodiments, to enable the clamping part 321 to drive the chuck 34, the clamping part 321 includes a mounting part 3211 and a fourth connecting part 3212. The mounting part 3211 is connected to the first connecting part 322 at an angle. The fourth connecting part 3212 is fixedly connected to the mounting part 3211 and detachably connected to the chuck 34. Exemplarily, the mounting part 3211 can be fixed to the first connecting part 322 by welding.

[0040] When the chuck 34 is mounted on the fourth connecting part 3212, and the first connecting part 322 drives the fourth connecting part 3212 to move through the mounting part 3211, the fourth connecting part 3212 can drive the chuck 34 to move away from or towards the top of the mounting base 31, so that the chuck 34 moves away from or towards the top of the mounting base 31.

[0041] Combination Figure 1 and Figure 2 In some embodiments, in order to achieve detachable connection between the chuck 34 and the fourth connecting part 3212, the end face of the fourth connecting part 3212 facing away from the mounting part 3211 and the chuck 34 are provided with an embedding groove 3213 and an embedding member 341, which is embedded in the embedding groove 3213.

[0042] The mating structure of the insert 341 and the insert groove 3213 greatly simplifies the connection and separation of the chuck 34 and the fourth connecting part 3212. During installation, simply align the insert 341 on the chuck 34 with the insert groove 3213 on the fourth connecting part 3212 and apply pressure to complete the insertion connection. No complex tools or cumbersome steps are required, shortening installation time. Similarly, during disassembly, applying appropriate external force to overcome the friction of the insertion allows the insert 341 to separate from the insert groove 3213, enabling quick removal of the chuck 34 and improving the efficiency of equipment maintenance and chuck replacement.

[0043] When the insert 341 is inserted into the insert groove 3213, the chuck 34 can be precisely positioned on the fourth connecting part 3212. The relative position of the chuck 34 on the fourth connecting part 3212 is fixed, avoiding problems such as shaking or displacement of the chuck 34 during operation, and ensuring the connection stability between the chuck 34 and the fourth connecting part 3212. The fitting structure between the insert 341 and the insert groove 3213 increases the contact area between the chuck 34 and the fourth connecting part 3212, making the connection between the chuck 34 and the fourth connecting part 3212 more secure. After the insert 341 is inserted into the insert groove 3213, there is a certain friction and clamping force between the two, which can effectively prevent the chuck 34 from loosening and falling off due to vibration, impact and other factors during operation, reducing the risk of accidents caused by the chuck 34 falling off, and ensuring the personal safety of the operator and the normal operation of the equipment.

[0044] In some embodiments, to facilitate the installation of the insert 341 into the insert groove 3213, the insert 341 includes a dovetail slider, and the insert groove 3213 includes a dovetail groove.

[0045] The unique shape of the dovetail groove provides a natural guiding function. When installing the dovetail slider into the groove, the inclined side of the groove guides the slider to slide accurately along the predetermined trajectory, eliminating the need for operators to spend a lot of time and effort on precise alignment. Even in environments with poor visibility or limited space, installation can be completed quickly and smoothly, improving installation efficiency.

[0046] The special shapes of the dovetail groove and the dovetail slider enable a self-locking mechanism when they are connected. Once the dovetail slider is embedded in the dovetail groove, it cannot disengage on its own in the direction perpendicular to the connecting surface due to the oblique edge of the dovetail groove, unless a significant external force is applied to make it slide out along the oblique edge. This self-locking function effectively prevents the chuck 34 from loosening or falling off during operation due to vibration, impact, or other factors, ensuring the stability and reliability of the chuck 34's installation.

[0047] The dovetail slider and dovetail groove have excellent repeated disassembly and assembly performance. During multiple disassembly and assembly processes, as long as the operation is carried out in accordance with regulations, the shape and size of the dovetail groove and dovetail slider will not change significantly, and the connection performance can remain stable. This ensures that the connection quality and performance between the chuck 34 and the fourth connecting part 3212 are consistent after each installation, thereby improving the maintainability and service life of the equipment.

[0048] Combination Figure 1 In some embodiments, to ensure the stability of the clamping wing plate 12, the clamping assembly 30 further includes a pad 35. The pad 35 is disposed on the mounting base 31. The wing plate 12 is located between the pad 35 and the clamp 34. The pad 35 supports the wing plate 12, so that the wing plate 12 is subjected to uniform pressure, thereby ensuring the stability of the clamping.

[0049] In some embodiments, in order to ensure the stability of the chuck 34 in clamping the wing plate 12, when the chuck 34 abuts against the wing plate 12, the projection of the chuck 34 on the base 20 along the height direction of the pad 35 overlaps at least partially with the projection of the pad 35 on the base 20. When the chuck 34 contacts the wing plate 12, the overlapping projection design makes the force point of the chuck 34 and the support surface of the pad 35 form a mechanical coupling in the vertical direction. By increasing the support area in the vertical direction, the clamping force is effectively dispersed, and the lateral moment caused by the eccentric force of the wing plate 12 is reduced, thereby reducing the risk of the chuck 34 tilting or slipping during the clamping process.

[0050] It is understandable that after the wing plate 12 is placed on top of the pad 35, and simultaneously, before the pusher 33 drives the clamping member 32 to rotate on the pad 35 and the clamping member 32 drives the chuck 34 to move towards the top of the pad 35, the projection of the chuck 34 on the base 20 is offset from the projection of the pad 35 on the base 20 along the height direction of the pad 35. During the process of placing the wing plate 12 on top of the pad 35, the chuck 34 will not block the center beam 10, so as to facilitate the placement of the center beam 10.

[0051] Combination Figure 1 In some embodiments, the clamping device further includes a first support member 40 to support the body 11. The first support member 40 is disposed on the base 20 and is used to support the body 11. Two clamping assemblies 30 are spaced apart from the first support member 40.

[0052] The first support member 40 is mounted on the base 20, providing a stable support platform for the entire structure. The main body 11 is placed on the first support member 40 and fixed by two spaced clamping components 30, so that the weight and force of the main body 11 can be evenly transmitted to the first support member 40 and the base 20. This effectively disperses stress, reduces structural deformation or damage caused by excessive local stress, and thus enhances the structural stability of the entire device.

[0053] Combination Figure 1 In some embodiments, to support the body 11, the clamping assembly 30 further includes a second support member 36. The second support member 36 is disposed on the first support member 40 and connected to the mounting base 31. The body 11 is disposed on the second support member 36.

[0054] The second support member 36 is mounted on the first support member 40, which in turn is mounted on the base 20, providing a stable support platform for the entire structure. The main body 11 is placed on the second support member 36 and secured by two spaced-apart clamping components 30. This allows the weight and force of the main body 11 to be evenly distributed across the second support member 36, the first support member 40, and the base 20, effectively dispersing stress and reducing structural deformation or damage caused by excessive local stress, thereby enhancing the structural stability of the entire device.
