Description

TECHNICAL FIELD

[0002] In the production and assembly process of a rail vehicle, a process support is generally used for supporting and fixing. In particular, when assembling an outer plate and a framework of a cab of the rail vehicle, the outer plate and the framework are welded together by a segment welding process, and the welding amount is large. If there is no effective support and limiting, the outer plate and the framework may be deformed by welding. When the outer plate and the framework of the cab are assembled, the outer plate is welded to a plate beam on the framework. In the related art, a process support is used to support and limit the plate beam of the framework when the cab is assembled, so as to limit the welding deformation of the plate beam of the framework and the welding deformation of the outer plate.

In order to ensure stable support and limiting of the plate beam of the framework, two or three process supports are generally used in cooperation.

DETAILED DESCRIPTION

[0022] The embodiments of the application will be further described in detail below in combination with the drawings and examples. The following examples are used to illustrate the application, but cannot be used to limit the scope of the application.

[0023] The following will be described in combination with Figures 1 to 2 The process support of the application.

[0024] As Figures 1 to 2 shown, the process support provided by the embodiment of the application includes a telescopic mechanism, a locking mechanism, a second connecting part 1 and at least two first connecting parts.

[0025] Specifically, the telescopic mechanism has a fixed end and a telescopic end, and the telescopic end can be close to or away from the fixed end.

[0026] Each first connecting part is arranged at the telescopic end, and each first connecting part is used to connect to a component to be supported. At least two first connecting parts are arranged, so that the process support provided by the embodiment of the application has at least two support points for the component to be supported.

[0027] The second connecting part 1 is arranged at the fixed end and is used for being fixedly connected to a fixed base point. The fixed base point is selected according to the distribution of surrounding parts of the to-be-supported part. In general, a part arranged opposite to the to-be-supported part is selected as the fixed base point.

[0028] The second connecting part 1 is connected to the fixed base point, and each first connecting part is connected to the to-be-supported part. The telescopic mechanism is adjusted. If the telescopic end of the telescopic mechanism gradually moves away from the fixed end, the process support provided by the embodiment of the present application can generate a force on the to-be-supported part in a direction away from the fixed base point. If the telescopic end of the telescopic mechanism gradually moves towards the fixed end, the process support provided by the embodiment of the present application can generate a force on the to-be-supported part in a direction towards the fixed base point. The telescopic mechanism can be adjusted according to requirements.

[0029] For example, if it is required to limit the deformation of the to-be-supported part in a direction towards the fixed base point, the telescopic end of the telescopic mechanism needs to be gradually moved away from the fixed end when the telescopic mechanism is adjusted, until the force generated by the first connecting part on the to-be-supported part reaches a predetermined value. If it is required to limit the deformation of the to-be-supported part in a direction away from the fixed base point, the telescopic end of the telescopic mechanism needs to be gradually moved towards the fixed end when the telescopic mechanism is adjusted, until the force generated by the first connecting part on the to-be-supported part reaches a predetermined value.

[0030] When the outer plate of the cab is assembled with the framework, the welding and fixing of the outer plate and the framework plate beam can cause the outer plate and the framework to deform in a direction away from the interior space of the framework. When the process support provided by the embodiment of the present application is used for support, a traction beam corresponding to the interior space of the framework on the vehicle chassis can be selected as the fixed base point, and the second connecting part 1 is connected to the traction beam. Each first connecting part is connected to the framework plate beam. When the telescopic mechanism is adjusted, the telescopic end of the telescopic mechanism needs to be gradually moved towards the fixed end, so that the first connecting part can generate a force on the framework plate beam in a direction towards the traction beam.

[0031] The first connecting part is rotationally connected to the telescopic end, and the rotation axes of each first connecting part relative to the telescopic end are parallel to each other. The locking mechanism is arranged between the first connecting part and the telescopic end, and the locking mechanism can be switched between a locked state and an unlocked state. When the locking mechanism is switched to the locked state, the first connecting part is fixed relative to the telescopic end. When the locking mechanism is switched to the unlocked state, the first connecting part can rotate relative to the telescopic end.

[0032] In the process of assembling the outer plate of the cab of the rail vehicle with the framework, the first connecting part is connected with the framework plate beam, the second connecting part 1 is connected with the traction beam of the vehicle chassis, the locking mechanism is switched to the unlocking state, the telescopic mechanism is adjusted to generate a force on the framework plate beam in the direction close to the traction beam, when the force reaches a predetermined value, the adjustment of the telescopic mechanism is stopped, and the locking mechanism is switched to the locking state to ensure the stability of the process support.

[0033] In this way, when the telescopic mechanism is adjusted, the locking mechanism is in the unlocking state, and in the process of the telescopic end and the fixed end approaching each other, each first connecting part can be adaptively rotated relative to the telescopic end under the action of the telescopic end of the telescopic mechanism, and each first connecting part is uniformly stressed, thereby uniformly stressing each support point of the framework plate beam, solving the problem of uneven stress of each support point of the framework plate beam in the related art when supporting and limiting the framework plate beam, improving the supporting and limiting effect of the framework plate beam, and being conducive to improving the product quality.

[0034] In addition, when the process support provided by the embodiment of the application is used to support the framework plate beam, only the telescopic mechanism needs to be adjusted to support the framework plate beam by each first connecting part, without the need for separate adjustment operations of each first connecting part, which is simple to operate and is conducive to improving work efficiency.

[0035] It should be noted that after adjusting the telescopic mechanism and switching the locking mechanism to the locking state, the stability of the process support can be detected by visual inspection and simple tension test to ensure the connection firmness.

[0036] In the embodiment of the application, the locking mechanism includes an intermediate connecting rod 2 and a first fastening assembly.

[0037] Any two adjacent first connecting parts are correspondingly provided with an intermediate connecting rod 2, any one of the two adjacent first connecting parts is a first one, and the other is a second one. The first end of the intermediate connecting rod 2 is rotatably connected to the first one, and the rotation axis of the intermediate connecting rod 2 relative to the first one is parallel to the rotation axis of the first connecting part relative to the telescopic end.

[0038] The second end of the intermediate connecting rod 2 is in sliding fit with the second one, and the first fastening assembly can fasten the second one and the second end of the intermediate connecting rod 2 together to limit the relative sliding of the second end of the intermediate connecting rod 2 and the second one, so that the intermediate connecting rod 2 and the second one are relatively fixed, thereby enabling the first one, the second one and the intermediate connecting rod 2 to be relatively fixed.

[0039] Any two adjacent first connecting parts are correspondingly provided with an intermediate connecting rod 2 and a first fastening assembly. The relative fixation of any two adjacent first connecting parts can be achieved through the first fastening assembly, so that each first connecting part is relatively fixed to the telescopic end of the telescopic mechanism. At this time, the corresponding locking mechanism is in a locked state.

[0040] By loosening the connection between the first fastening assembly and the second end and the intermediate link 2, the second end of the intermediate link 2 can be allowed to slide relative to the second end, so that each first connection part can rotate relative to the telescopic end of the telescopic mechanism. At this time, the corresponding locking mechanism is in the unlocked state.

[0041] In a specific embodiment, there are three first connection parts, referring to Figure 1 Of the three first connecting parts, the one located in the middle is the second part, and the other two are the second parts. Accordingly, there are two intermediate connecting rods 2. The first connecting parts located on both sides of the three first connecting parts are respectively rotatably connected to the first ends of the two intermediate connecting rods 2, and the first connecting part located in the middle is slidably engaged with the second ends of the two intermediate connecting rods 2.

[0042] Specifically, the two intermediate connecting rods 2 are respectively located on both sides of the second one, a first connecting hole 3 is provided on the second one, and a strip hole 4 is provided at the second end of the intermediate connecting rod 2, and the strip hole 4 extends along the axis direction of the intermediate connecting rod 2. Figure 2 .

[0043] The first fastening assembly includes a first fastener and a tightening member. The first fastener can pass through the strip-shaped hole 4 and slide along the extension direction of the strip-shaped hole 4. The first end of the first fastener passes through the first connecting hole 3 and the strip-shaped holes 4 of the two intermediate connecting rods 2. The second end of the first fastener is provided with a limiter. The tightening member is threadedly connected to the first end of the first fastener.

[0044] Rotating the tightening member relative to the first fastening member moves the tightening member toward or away from the stopper. As the tightening member approaches the stopper, the tightening member and the stopper respectively abut against the separated sides of the two intermediate connecting rods 2. The squeezing action of the tightening member and the stopper on the intermediate connecting rods 2 and the first connecting portion, coupled with the friction between the two adjacent connecting rods, restricts relative sliding between the two intermediate connecting rods 2 and the second connecting rod, securing the two intermediate connecting rods 2 relative to the second connecting rod. This corresponds to the locked state of the locking mechanism.

[0045] The tightening member is rotated relative to the first fastening member, so that the tightening member gradually moves away from the limiting portion until the tightening member and the limiting portion are both out of contact with the intermediate connecting rod 2. At this time, the tightening member and the limiting portion have an extrusion effect on the intermediate connecting rod 2 and the first connecting portion, and the friction between the two adjacent ones is reduced or even disappears. The two intermediate connecting rods 2 and the second one can slide relative to each other. At this time, the corresponding locking mechanism is in the unlocked state.

[0046] The first fastener can be, but is not limited to, a locking bolt, and the nut of the locking bolt serves as the limiting portion. The rotating member can be, but is not limited to, a locking nut, which is threadedly connected with the locking bolt.

[0047] In some embodiments, the first connecting portion is in the form of a rod, and the first connecting portion is welded to the component to be supported by spot welding.

[0048] In other embodiments, the first connecting portion is in the form of a clamp, and the first connecting portion clamps the component to be supported.

[0049] In the present embodiment, the first connecting portion is in the form of a clamp, and specifically, the first connecting portion includes a connecting rod 5 and a clamping assembly.

[0050] The clamping assembly is connected to the telescopic end of the telescopic mechanism through the connecting rod 5. Specifically, the connecting rod 5 is arranged between the clamping assembly and the telescopic end, the first end of the connecting rod 5 is rotationally connected with the telescopic end, and the second end of the connecting rod 5 is connected with the clamping assembly.

[0051] The clamping assembly includes a pair of clamping arms 6, which are arranged in a cross shape and can rotate relative to each other. The relative rotation of the pair of clamping arms 6 can clamp or release the component to be supported.

[0052] When the clamping assembly clamps or releases the component to be supported, neither the component to be supported nor the clamping assembly is damaged. Compared with the mode of spot welding the first connecting portion to the component to be supported, when the first connecting portion is detached from the component to be supported, the cutting and polishing operations on the welding spot can be avoided, thereby avoiding the damage such as scratches and deformation to the first connecting portion and the component to be supported, and the product quality is further improved.

[0053] The clamping assembly as a whole can rotate relative to the second end of the connecting rod 5, and the rotation axis of the clamping assembly relative to the connecting rod 5 is parallel to the axis of the connecting rod 5.

[0054] When the pair of clamping arms 6 rotate relative to each other, the direction in which the ends of the pair of clamping arms 6 away from the connecting rod 5 approach each other is the clamping direction of the clamping assembly. In the present embodiment, the first connecting portion is in the form of a clamping assembly that can rotate relative to the connecting rod 5 about the axis of the connecting rod 5, and by rotating the clamping assembly as a whole relative to the connecting rod 5, the clamping direction of the clamping assembly can be adjusted.

[0055] For the application scenario of assembling the outer plate of the cab with the framework, the clamping assembly clamps the framework plate beam, and a pair of clamping arms 6 clamp the opposite two side surfaces of the framework plate beam. The outer plate of the cab is not a plane, and has inclined surfaces and arc surfaces. Correspondingly, the plate beams at different positions of the framework are also not planes, and the support points of the framework plate beams at different positions have different requirements for the clamping direction of the clamping assembly. In the embodiment of the present application, the first connecting part is arranged in a structure form in which the clamping direction of the clamping assembly is adjustable, which can meet the clamping and fixing requirements of the plate beams of various shapes at different positions, and has strong adaptability.

[0056] In some embodiments, a bearing or the like component can be arranged between the clamping assembly and the second end of the connecting rod 5 to realize the rotary connection of the clamping assembly and the second end of the connecting rod 5.

[0057] The end of the clamping assembly for connecting the connecting rod 5 is the connecting end of the clamping assembly. In further embodiments of the present application, one of the connecting end of the clamping assembly and the second end of the connecting rod 5 is provided with an internal thread, and the other is provided with an external thread. The internal thread and the external thread are matched, and the axes of the internal thread and the external thread are parallel to the axis of the connecting rod 5. That is, the connecting end of the clamping assembly and the second end of the connecting rod 5 are connected through a threaded pair. By rotating the connecting end of the clamping assembly relative to the second end of the connecting rod 5, the clamping direction of the clamping assembly can be adjusted, and the adjustment angle range of the clamping direction of the clamping assembly is 0°~360°.

[0058] In addition, when the connecting end of the clamping assembly is rotated relative to the second end of the connecting rod 5, the connecting end of the clamping assembly will also displace along the axis direction of the connecting rod 5, that is, the distance between the clamping assembly as a whole and the telescopic end of the telescopic mechanism is adjusted, realizing the telescopic adjustment of the first connecting part. In specific embodiments, the length of the threaded pair of the connecting end of the clamping assembly and the second end of the connecting rod 5 can be appropriately increased to ensure the telescopic adjustment capability of the first connecting part.

[0059] Specifically, an external thread is arranged at the second end of the connecting rod 5, and an internal thread is arranged at the connecting end of the clamping assembly, so that the second end of the connecting rod 5 is arranged inside the connecting end of the clamping assembly and is connected in a threaded manner.

[0060] For the structure of the clamping assembly, a pair of clamping arms 6 are rotatably connected, the relative rotation axes of the pair of clamping arms 6 are perpendicular to the axis of the connecting rod 5, and the rotation connection points of the pair of clamping arms 6 are located between the two ends of the clamping arms 6. The clamping assembly further comprises a connecting seat 7, a first transmission rod 8 and a second transmission rod 9.

[0061] The first end of the connecting seat 7 is the connecting end of the clamping assembly, and the first transmission rod 8 and the second transmission rod 9 are arranged between the pair of clamping arms 6 and the connecting seat 7. Specifically, the first end of the first transmission rod 8 is rotationally connected with the second end of the connecting seat 7, and the second end of the first transmission rod 8 is rotationally connected with the first end of one of the pair of clamping arms 6. The first end of the second transmission rod 9 is rotationally connected with the second end of the connecting seat 7, and the second end of the second transmission rod 9 is rotationally connected with the first end of the other of the pair of clamping arms 6.

[0062] The rotation axis of the first transmission rod 8 relative to the connecting seat 7, the rotation axis of the first transmission rod 8 relative to the clamping arm 6, the rotation axis of the second transmission rod 9 relative to the clamping arm 6, and the rotation axis of the second transmission rod 9 relative to the connecting seat 7 are parallel to each other. Moreover, the rotation axis of the second transmission rod 9 relative to the connecting seat 7 coincides with the rotation axis of the first transmission rod 8 relative to the connecting seat 7, and the first transmission rod 8, the second transmission rod 9, and the pair of clamping arms 6 form a hinged quadrilateral structure.

[0063] When connecting each first connecting part with the framework plate beam, the locking mechanism is switched to the unlocked state, each connecting rod 5 can rotate relative to the telescopic end of the telescopic mechanism, and the position of each clamping assembly can be adjusted. According to the shape of the framework plate beam, the clamping direction of each clamping assembly is adjusted so that the pair of clamping arms 6 of each clamping assembly can be located on the opposite sides of the framework plate beam. Then, the first transmission rod 8 and the second transmission rod 9 are manually forced to reduce the included angle between the first transmission rod 8 and the second transmission rod 9, so that the second end of the pair of clamping arms 6 approaches the surface of the framework plate beam until the second end of the pair of clamping arms 6 contacts the opposite side surfaces of the framework plate beam. Then, the telescopic mechanism is adjusted again so that the telescopic end approaches the fixed end, thereby driving the connecting end of the clamping assembly to gradually move away from the framework plate beam, while the relative position between the second end of the pair of clamping arms of the clamping assembly and the framework plate beam remains basically unchanged, so that the included angle between the first transmission rod 8 and the second transmission rod 9 and the included angle between the pair of clamping arms 6 are further reduced, so that the second end of the pair of clamping arms 6 exerts a certain extrusion force on the framework plate beam. As the distance between the telescopic end and the fixed end gradually decreases, the extrusion force exerted by the second end of the pair of clamping arms 6 on the framework plate beam gradually increases, and the connection and fastening degree of the clamping assembly and the framework plate beam gradually increases.

[0064] In this way, the clamping assembly does not need to be additionally provided with a separate driving member, and the operator can automatically clamp the clamping assembly after contacting the framework plate beam under the action of the telescopic mechanism, and the structure is simple.

[0065] In a further embodiment, the second end of the pair of clamping arms 6 is provided with a friction increasing structure, which can increase the friction between the second end of the clamping arm 6 and the framework plate beam, and can further improve the connection and fastening degree of the clamping assembly and the framework plate beam.

[0066] Specifically, the friction-increasing structure can be but is not limited to a toothed protruding structure or a granular protruding structure arranged at the second end of the clamping arm 6.

[0067] In an optional embodiment, the part of the clamping arm 6 away from the connecting seat 7 can also be arranged in an arc shape, as shown in Figure 1 In this way, the clamping arm 6 can avoid interfering with the edge of the skeleton plate beam, and the second end of the clamping arm 6 can effectively act on the side surface of the skeleton plate beam.

[0068] In the embodiment of the present application, the telescopic mechanism comprises a first rod 10, a second rod 11 and a rotating rod 12.

[0069] The axis of the first rod 10 coincides with the axis of the second rod 11, and the end of the first rod 10 away from the second rod 11 is the telescopic end, and the end of the second rod 11 away from the first rod 10 is the fixed end.

[0070] The axis of the rotating rod 12 coincides with the axis of the first rod 10 and the axis of the second rod 11, the first end of the rotating rod 12 is connected with the first rod 10 through a first threaded structure, and the second end of the rotating rod 12 is connected with the second rod 11 through a second threaded structure, and the thread rotation direction of the first threaded structure is opposite to that of the second threaded structure.

[0071] After the second connecting part 1 is connected to the fixed base point, the second rod 11 is fixed relative to the fixed base point and cannot rotate relative to the fixed base point about its own axis. After the pair of clamping arms 6 of the clamping assembly of each first connecting part are respectively located on opposite sides of the skeleton plate beam, through the interaction between the clamping assembly of each first connecting part and the skeleton plate beam, the rotation of each first connecting part about the axis of the first rod 10 relative to the skeleton plate beam can be limited, and the rotation of the first rod 10 about its own axis relative to the skeleton plate beam can be limited. That is, neither the first rod 10 nor the second rod 11 can rotate about its own axis. By applying a torque to the rotating rod 12, the rotating rod 12 can be rotated relative to the first rod 10 and the second rod 11. Thus, the first rod 10 and the second rod 11 can be moved closer to or farther away from each other, and the telescopic end and the fixed end can be moved closer to or farther away from each other.

[0072] Specifically, external threads can be arranged on the first rod 10 and the second rod 11, and internal threads can be arranged on the rotating rod 12, so that the two ends of the rotating rod 12 are respectively sleeved on the outside of the first rod 10 and the second rod 11 and are respectively threadedly connected.

[0073] In a further embodiment, the process support also comprises an adapter 13 arranged between the first rod 10 and each connecting rod 5, and the axis of the adapter 13 is perpendicular to the axis of the first rod 10, as shown in Figure 1The adapter 13 is fixedly connected with the first rod 10, the first ends of the connecting rods 5 are spacedly distributed along the axis of the adapter 13, and the first ends of the connecting rods 5 are symmetrically distributed about the axis of the adapter 13, the axis of the first rod 10, the axis of the second rod 11, the axis of the rotating rod 12 and the axis of each connecting rod 5 are located in the same plane.

[0074] In this way, the stress uniformity of each connecting rod 5 can be further improved, and the stress uniformity of each support point of the framework plate beam can be further improved.

[0075] In the embodiment, to ensure that the axis of each connecting rod 5 and the axis of the first rod 10 are located in the same plane, the adapter 13 can be provided as a C-shaped plate, the groove of the C-shaped plate faces each connecting rod 5, and the end of each connecting rod 5 can extend into the groove of the C-shaped plate. The end of the first rod 10 is fixedly connected to the opposite side of the side where the groove of the C-shaped plate is located. For details, refer to the description of the first embodiment. Figure 1 .

[0076] When connecting the second connecting part 1 with the fixed base point, welding can be used. The welding process and the division of the welding points will consume the second connecting part 1 to a certain extent. In the embodiment, the second connecting part 1 and the fixed end of the telescopic mechanism are provided in a detachable connection mode, so that the second connecting part 1 can be replaced, thereby prolonging the service life of the process support.

[0077] In the embodiment, the second connecting part 1 and the fixed end are partially overlapped, the second connecting part 1 is provided with at least two second connecting holes, the fixed end is provided with at least two third connecting holes 14, and the second connecting part 1 is connected with the fixed end through a second fastening assembly.

[0078] The second fastening assembly includes a fastening bolt and a fastening nut, the fastening bolt is screwed with the fastening nut after passing through the second connecting hole on the second connecting part 1 and the third connecting hole 14 of the fixed end.

[0079] To facilitate the connection of the fixed end and the second connecting part 1, a C-shaped plate can be provided on the fixed end, and the second connecting part 1 is provided as a flat plate structure, so that the second connecting part 1 can extend into the groove of the C-shaped plate.

[0080] It should be noted that the clamping assembly in the process support in the embodiment of the present application completes the clamping action under the telescopic action of the telescopic mechanism. However, since each part in the process support is a rigid member, even if it is applied to a scene where the deformation of the supported part in the direction away from the fixed base point needs to be limited, in addition to being able to prevent the supported part from deforming in the direction away from the fixed base point, it can also support the supported part to a certain extent, and can prevent the supported part from deforming in the direction close to the fixed base point.

[0081] In summary, the process support design provided by the embodiment of the present application is ingenious, and can flexibly adjust the clamping direction of each clamping assembly according to actual operation requirements, and accurately select the fixed position of the clamping assembly and the framework plate beam. When fastening and telescopic adjustment, only the rotating rod 12 needs to be rotated, the operation is simple, and when fastening and telescopic adjustment, the locking mechanism is in the unlocked state, each connecting rod 5 is uniformly stressed, each support point of the framework plate beam is uniformly stressed, effectively avoiding the problems of complicated operation and uneven stress of each support point of the framework plate beam caused by the need to fasten and tension each first connecting part separately. The stability and reliability of supporting the framework plate beam are greatly improved, and the flatness of the framework and the outer plate is effectively ensured. Moreover, the clamping assembly is connected with the framework plate beam in a clamping manner, avoiding spot welding, and avoiding the complicated processes such as cutting and polishing caused by disassembly of the process support after assembly, greatly shortening the production cycle, reducing the labor cost, avoiding damage to the material surface caused by cutting and polishing, greatly improving the production efficiency and product quality, and providing a better support solution for the production of the cab of the railway vehicle.
