Description

Technical Field

[0001] This invention relates to the field of rail vehicle manufacturing and provides a device for treating bogie weld seams. Background Technology

[0002] The bogie is a crucial running gear component of a rail vehicle, responsible for supporting the car body and transmitting traction and braking forces. The quality of its welds directly affects the safety of vehicle operation. After bogie welding, defects such as incomplete penetration, slag inclusions, porosity, and oxides often occur at the weld root. These defects must be removed through a root cleaning process to ensure that subsequent welding forms a fully penetrated joint.

[0003] Currently, the equipment used for cleaning bogie welds has significant shortcomings. Different bogie models have varying overall dimensions and weld heights, and the working heights for different welds on the same bogie also differ.

The following examples are for illustrative purposes only and should not be construed as limiting the scope of the invention.

[0026] In this invention, unless otherwise expressly specified and limited, the first feature "on" or "below" the second feature may be in direct contact with the first and second features, or indirect contact through an intermediate medium. In the description of this specification, references to terms such as "one embodiment," "some embodiments," "example," "specific example," or "some examples," etc., indicate that a specific feature, structure, material, or characteristic described in connection with that embodiment or example is included in at least one embodiment or example of the invention.

Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0027] like Figures 1 to 4 As shown, this embodiment of the invention provides a bogie weld treatment device, including: a mounting bracket 100; a height adjustment component 200 disposed on the mounting bracket 100, the height adjustment component 200 including a first drive transmission structure and a lifting plate 210 disposed at a relative interval, the first drive transmission structure being used to drive the lifting plate 210 to move in the vertical direction; a clamping component 300 fixed to the inner surface of the lifting plate 210 for clamping the bogie; and a weld root cleaning device 400 disposed on the mounting bracket 100 for treating the weld root of the bogie.

[0028] This invention uses a clamping assembly 300 to clamp the bogie to be processed. Since the clamping assembly 300 is fixed to the lifting plate 210, it can drive the bogie to rise and fall with the lifting plate 210. Through the smooth, stepless rising and falling of the lifting plate 210, the bogie height can be continuously adjusted without stopping the machine. This solves the problem of existing weld cleaning devices requiring machine stoppage for height adjustment, leading to work interruptions and low efficiency. The weld cleaning device 400 is used at the weld location corresponding to the bogie to remove defects such as incomplete penetration, slag inclusions, porosity, and oxides at the weld root, ensuring the weld quality of the bogie.

[0029] like Figure 1 As shown, a pair of spaced-apart lifting plates 210 are provided, each with a clamping assembly 300. The pair of clamping assemblies 300 clamp the bogie from both sides, providing the necessary working conditions. The distance between the two lifting plates 210 is set according to the bogie size; this distance can be fixed or flexibly adjustable. For example, to accommodate bogies of different models or sizes and to accommodate various specifications, the distance between the lifting plates 210 can be adjusted. That is, one or both lifting plates 210 can be set to slide horizontally, thereby adjusting the distance between the two lifting plates 210.

[0030] To further improve the continuity of operations, increase overall processing efficiency, and reduce manual auxiliary operations, according to an embodiment of the present invention, the bogie weld treatment device further includes: a horizontal adjustment component 500, which includes a second drive transmission structure. The weld cleaning device 400 is connected to the second drive transmission structure and can move horizontally under the drive of the second drive transmission structure.

[0031] The horizontal adjustment component 500 drives the weld cleaning device 400 to move horizontally through the second drive transmission structure. It can flexibly adjust the processing position according to the distribution of welds, so that the cleaning device can quickly and accurately align with the weld to be processed. No manual repositioning is required, which further improves the automation level and positioning accuracy of the equipment, reduces auxiliary operation time, and forms a multi-dimensional position adjustment capability with the height adjustment structure. It can adapt to the weld processing needs of different areas and directions on the bogie, and significantly improves the flexibility of operation and the scope of application.

[0032] To achieve bogie height adjustment, the first drive transmission structure can adopt any of the following forms. For example... Figure 1 As shown, the first drive transmission structure includes a first motor 220, a gear transmission assembly, and a lifting screw 221. The output end of the first motor 220, the gear transmission assembly, and the lifting screw 221 are sequentially connected in a transmission manner, and the upper end of the lifting screw 221 is fixedly connected to the lifting plate 210.

[0033] In this embodiment, the first motor 220 drives the lifting screw 221 to rotate through a gear transmission assembly, thereby driving the lifting plate 210 to achieve vertical lifting movement. This transmission structure provides smooth transmission and reliable power transmission, and can accurately control the lifting stroke and moving speed of the lifting plate 210, ensuring the accuracy and stability of height adjustment. The overall structure is compact, with high transmission efficiency, and can continuously and stably output driving force to meet the automated height adjustment needs under different working conditions, effectively avoiding problems such as jamming and deviation.

[0034] Furthermore, the gear transmission assembly includes two first bevel gears 222, a rotating shaft 223, and two second bevel gears 224. Two lifting screws 221 are provided, corresponding to the two lifting plates 210 respectively. Each lifting screw 221 is configured with one first bevel gear 222 and one second bevel gear 224. For example... Figure 1 As shown, one of the first bevel gears 222 is connected to the output end of the first motor 220, and the other first bevel gear 222 is arranged away from the output end of the first motor 220. The two first bevel gears 222 are connected by a rotating shaft 223. The second bevel gear 224 is connected to the lower end of the lifting screw 221. Each first bevel gear 222 is meshed with the corresponding second bevel gear 224.

[0035] Thus, when the device is working, the first motor 220 drives the first bevel gear 222 close to it to rotate. Under the action of the rotating shaft 223, the two first bevel gears 222 rotate synchronously. Then, the two rotating first bevel gears 222 drive the second bevel gear 224 meshing with them to rotate. The second bevel gear 224 drives the lifting screw 221 to rotate, thereby realizing the smooth stepless lifting of the lifting plate 210 and driving the bogie placed on it to adjust the height. The whole process does not require stopping the machine.

[0036] This embodiment utilizes two sets of bevel gears in conjunction with the rotating shaft 223 to achieve synchronous operation of the two lifting screws 221, driving the lifting plates 210 on both sides to rise and fall synchronously. This ensures good transmission synchronization and even power distribution, effectively guaranteeing consistent lifting movements of the two lifting plates 210 and avoiding workpiece tilting and positioning misalignment caused by asynchronous lifting. The bevel gear transmission operates smoothly with low noise, and combined with the screw structure, it allows for stepless height adjustment. The adjustment process is continuous and uninterrupted, requiring no machine downtime for debugging, significantly improving operational continuity and overall processing efficiency. Simultaneously, the high transmission precision further ensures the accuracy of bogie height adjustment and operational stability. Furthermore, using a single motor to drive both lifting plates 210 simplifies the overall configuration and saves costs.

[0037] In other embodiments, the first drive transmission structure can be driven by a cylinder or a hydraulic cylinder, and the bogie height can be adjusted without stopping the machine through pneumatic or hydraulic control. The structure is simple, the layout is compact, and the action response is rapid, which can realize the rapid lifting and lowering adjustment of the lifting plate 210.

[0038] Alternatively, the first drive transmission structure can also adopt an electric push rod transmission structure, a chain transmission structure, a worm gear transmission structure, a crank connecting rod transmission structure, etc., which can be flexibly adjusted according to actual needs.

[0039] According to one embodiment of the present invention, the height adjustment assembly 200 further includes a limiting rod 230, and each lifting plate 210 is arranged between two limiting rods 230. The limiting rod 230 is provided with a limiting groove along the height direction for the lifting plate 210 to be inserted.

[0040] like Figures 1 to 3 As shown, the limiting rod 230, in conjunction with the limiting slide, forms a guiding constraint on the lifting plate 210, limiting its movement trajectory and ensuring smooth movement only in the vertical direction. This effectively avoids problems such as twisting, offsetting, and swaying during the lifting process. The reliable guidance of the double-sided limiting structure further improves the straightness and operational stability of the lifting action, ensuring that the two lifting plates 210 have the same posture, preventing the clamped bogie from tilting, ensuring the alignment accuracy and processing quality of subsequent root cleaning operations, and also reducing the lateral force on the transmission structure, extending the service life of the equipment.

[0041] According to one embodiment of the present invention, the mounting bracket 100 includes a base plate 110 and a shelf 120 mounted on the base plate 110. A lifting plate 210 is mounted on the shelf 120. A first motor 220 and a gear transmission assembly are mounted on the base plate 110. The base plate 110 is provided with a first bracket 225 for fixing the first motor 220. The lower end of the lifting screw 221 passes through the shelf 120 and is connected to the gear transmission assembly. The upper end of the lifting screw 221 is located above the shelf 120 and is connected to the lifting plate 210.

[0042] The mounting bracket 100 adopts a layered structure design. The base plate 110 serves as the equipment base, possessing excellent load-bearing capacity and providing stable support for all components of the machine. The shelf 120 is mounted above the base plate 110 and is used to assemble the height adjustment component 200 and the level adjustment component 500. Assembly space is reserved between the base plate 110 and the shelf 120 to facilitate the arrangement and installation of transmission components, while also providing operating space for equipment inspection and maintenance.

[0043] like Figure 1 As shown, the first motor 220 is fixedly mounted on the base plate 110 via the first bracket 225. This secure mounting effectively buffers the vibrations generated during motor operation, reducing the impact of vibration transmission on other components and ensuring stable power output. The base plate 110 is equipped with a pair of protruding inverted L-shaped mounting brackets 226. A rotating shaft 223 passes between the vertical plates of the two mounting brackets 226, achieving reliable positioning through the mounting brackets 226. First bevel gears 222 are mounted at both ends of the rotating shaft 223. The lower end of the lifting screw 221 passes through the horizontal plates of the shelf 120 and the mounting brackets 226, then connects to the second bevel gear 224. The upper end extends out of the shelf 120 and is fixed to the lifting plate 210. The first bevel gear 222 and the second bevel gear 224 are housed together in the internal space enclosed by the inverted L-shaped fixing frame 226. On the one hand, this provides physical protection for the meshing bevel gears, preventing external debris, structural components from scratching and colliding, reducing gear wear, and extending the service life of the transmission components. On the other hand, it makes full use of the space, achieving a compact structural design and ensuring gear meshing accuracy and transmission reliability.

[0044] Furthermore, the limiting rod 230 is fixedly installed on the shelf 120, and the lifting plate 210 is limited and guided by the limiting rod 230, so that it can only slide and rise smoothly in the vertical direction, effectively preventing the lifting plate 210 from twisting or deviating, and further improving the stability and alignment accuracy of the height adjustment mechanism.

[0045] To enable flexible movement of the weld cleaning device 400, the second drive transmission structure can adopt any of the following forms. For example... Figure 2As shown, the second drive transmission structure includes a second motor 510, a lead screw 511, and a slider 512. The output end of the second motor 510 is connected to the lead screw 511 for transmission. The slider 512 is sleeved on the lead screw 511, and the weld cleaning device 400 is fixed to the top of the slider 512.

[0046] In this embodiment, the second motor 510 drives the lead screw 511 to rotate, which in turn drives the slider 512 sleeved on the lead screw 511 to perform linear reciprocating motion along the axial direction, thereby driving the weld cleaning device 400 to synchronously complete horizontal displacement. This transmission structure has high transmission precision and stable operation, and can achieve precise micro-adjustment with small strokes, quickly and accurately moving the cleaning device to the position of the weld to be processed. The overall structure is simple and compact, with direct power transmission and fast response speed. It can be used with the height adjustment component 200 to complete multi-dimensional position adjustment, adapting to the processing needs of welds in different positions. At the same time, the mechanical transmission is durable and can meet the requirements of long-term continuous operation of the equipment.

[0047] In other embodiments, the second drive transmission structure may also adopt a cylinder or hydraulic cylinder transmission structure, a synchronous belt transmission structure, an electric push rod transmission structure, a chain transmission structure, a gear and rack transmission structure, a crank connecting rod transmission structure, etc., which can be flexibly adjusted according to actual needs.

[0048] Furthermore, such as Figure 2 or Figure 3 As shown, the mounting bracket 100 includes a base plate 110 and a shelf 120. A vertical plate 130 is provided on the base plate 110, and the shelf 120 is fixed to the top of the vertical plate 130. The second motor 510 is fixed to the side wall of the vertical plate 130 by means of the second bracket 513. This mounting method can provide reliable support for the motor, effectively isolate the vibration generated by the motor operation, prevent the vibration from being transmitted to the lead screw 511 transmission mechanism, and ensure the transmission accuracy of horizontal adjustment.

[0049] One end of the lead screw 511 is connected to the output end of the second motor 510, and the other end is rotatably mounted on the underside of the shelf 120 via a bearing. This two-end support assembly effectively constrains the long lead screw 511, suppressing deflection, radial runout, and other problems that occur during its rotation, thus ensuring more stable operation and further guaranteeing the positioning and movement accuracy of the slider 512 and the weld cleaning device 400. The shelf 120 has an elongated sliding hole 121 along the length of the lead screw 511. The connecting part of the weld cleaning device 400 passes downward through the sliding hole 121 and connects to the slider 512 on the lead screw 511. This achieves stable power transmission while providing space for the horizontal reciprocating motion of the slider 512, resulting in a rational structural layout.

[0050] Furthermore, the first drive transmission structure and the second drive transmission structure are respectively arranged on both sides of the vertical plate 130, realizing the partitioned layout of the power mechanism. The two sides of the mechanism are independent of each other and do not interfere with each other, which can effectively avoid motion interference and vibration superposition of different transmission components during operation; at the same time, the partitioned layout makes the component arrangement more regular, which facilitates assembly, inspection and daily maintenance, and also makes the force on the whole machine more balanced, improving the long-term reliability of the equipment.

[0051] The aforementioned first motor 220 and second motor 510 can also be configured as a combination of servo motors and reducers. Servo motors offer precise positioning and sensitive response, and when combined with reducers to achieve speed reduction and torque increase, they can further improve the motion control precision of the transmission mechanism, making height adjustment and horizontal alignment actions more precise and controllable.

[0052] Based on the above embodiments, the clamping assembly 300 further includes clamping blocks 310 arranged at relatively intervals, and the distance between the two clamping blocks 310 can be adjusted.

[0053] The clamping assembly 300 adopts a double clamping block 310 structure with adjustable spacing, which can flexibly adjust the clamping width according to the external dimensions of different bogie specifications, and complete the workpiece clamping without replacing the entire fixture. Compared with traditional fixed fixtures, it can eliminate the fixture disassembly and assembly and cumbersome debugging procedures during model changeover, significantly shortening the operation time and reducing equipment modification costs. This structure is adaptable to the clamping requirements of multiple bogie models, and can meet the production operation mode of multiple varieties and small batches in the workshop, significantly improving versatility and flexibility of use. At the same time, the adjustable clamping block 310 can finely adjust the clamping position according to the actual shape of the workpiece to ensure clamping firmness, prevent the workpiece from loosening and shifting during processing, and ensure the accuracy of the cleaning operation.

[0054] For example, such as Figure 4 As shown, the clamping assembly 300 includes a fixed plate 320, a telescopic shaft 321 disposed on the fixed plate 320, and an adjusting rod 322. The fixed plate 320 is used to install on the lifting plate 210. The telescopic end of the telescopic shaft 321 is connected to a limit block 330. Two clamping blocks 310 are slidably connected to the lateral sides of the limit block 330 and can slide towards or away from each other along the limit block 330. Two adjusting rods 322 are respectively disposed on both sides of the telescopic rod, and the adjusting rods 322 are hinged between the fixed plate 320 and the clamping blocks 310.

[0055] During operation, the telescopic shaft 321 extends and retracts, causing the limiting block 330 to extend and retract synchronously. This, in turn, drives the adjusting rods 322 on both sides to rotate and open and close synchronously. Relying on the transmission action of the hinged connecting rod, the two clamping blocks 310 slide synchronously laterally along the limiting block 330, realizing automatic adjustment of the spacing. This allows for reliable clamping and unloading of bogies of different shapes and sizes. The simultaneous advance and retreat of the clamping blocks 310 on both sides ensures uniform clamping force, effectively guaranteeing that the bogie is centered and securely fixed. Furthermore, the adjustment operation is convenient, allowing for quick adaptation to various workpiece specifications, further improving the versatility and operational efficiency of the device.

[0056] Traditional clamping structures rely solely on a single mechanical clamping method to fix the workpiece without any auxiliary fixing structures. During the root cleaning operation, the bogie is prone to positional displacement due to factors such as cutting forces and equipment vibration, which can lead to deviations in the root cleaning position. In severe cases, this can result in scrapped welds and make it difficult to guarantee the yield rate of processed products.

[0057] To improve the stability and reliability of the bogie fixing clamp, the inner side of the limiting block 330 or the clamping block 310 is further provided with a fixing reinforcement structure to provide auxiliary reinforcement to the bogie in the clamping state.

[0058] In one example, the fixed reinforcement structure employs a vacuum adsorption component. After the clamping block 310 completes the mechanical clamping of the workpiece, the vacuum adsorption component is activated, utilizing negative pressure adsorption to form a double fixed constraint, significantly improving the reliability of workpiece positioning and effectively preventing bogie displacement during processing.

[0059] In another example, the fixed reinforcement structure uses an anti-slip rubber pad combined with a bolt locking structure. The anti-slip rubber pad increases the coefficient of friction between the clamping block 310 and the contact surface of the bogie, and the bolts further lock and position the workpiece, suppressing slippage and displacement.

[0060] It is understandable that the adjustment structure that drives the relative movement of the two clamping blocks 310 is not limited to the linkage form mentioned above. A two-way screw mechanism can also be used to drive the two clamping blocks 310 to slide towards or away from each other. This can also flexibly adjust the clamping distance to meet the clamping requirements of bogies of different specifications.

[0061] Based on the above embodiments, the weld cleaning device 400 is further equipped with a chip collection hood and a dust collection component on its outer side. The chip collection hood covers the outer periphery of the cleaning tool, and the dust collection component is connected to the chip collection hood through a pipeline. The dust collection function is activated simultaneously when the device is running. This allows for the real-time collection and removal of chips and dust, maintaining the cleanliness of the equipment interior, extending the service life of components, and improving the working environment, thus meeting the environmental protection requirements of the workshop.

[0062] The weld cleaning device 400 and the slider 512 are provided with an elastic floating connection structure (such as a spring or elastic pusher), which allows the cleaning tool to adapt to the weld surface in a small range. This compensates for possible machining errors in the bogie workpiece and unevenness of the weld surface. By adapting the tool to the workpiece surface, the cleaning depth is ensured to be uniform and consistent, improving the machining quality. At the same time, it buffers the cutting impact and protects the tool and the transmission mechanism.

[0063] The clamping block 310 integrates a pressure sensor, which is electrically connected to the equipment control system. By monitoring the clamping pressure in real time, the clamping stops when the set threshold is reached, thus achieving constant force clamping. This balances the reliability of the fixation with the protection of the workpiece, avoiding excessive clamping force that could cause deformation or surface damage to the bogie base material, or insufficient clamping force that could easily cause the workpiece to shift.

[0064] The bogie weld treatment device provided by this invention achieves automated weld cleaning of bogies through the cooperation of a height adjustment component, a clamping component, and a weld cleaning device. The height adjustment component, driven by a first drive transmission structure, moves the lifting plate vertically. It can automatically adjust the height according to the height differences of welds in different bogie models and locations, eliminating the need for manual adjustments and ensuring continuous operation. This improves the efficiency of the cleaning process, while the automated adjustment method offers higher precision and better consistency.

[0065] The clamping assembly reliably clamps and fixes the bogie, ensuring stable workpiece position during operation, preventing displacement deviation, and guaranteeing the quality of the weld root cleaning process. The weld root cleaning device effectively removes defects such as incomplete penetration, slag inclusions, porosity, and oxides from the weld root, eliminating the need for traditional carbon arc gouging. This avoids the formation of a carburized layer in the base material, ensuring weld metal purity, enabling subsequent welding to form a full-penetration joint, and improving weld structural strength, thereby ensuring the safe operation of the railway vehicle bogie.

[0066] The bogie weld treatment device of the present invention can achieve the following beneficial effects: Using the first motor as the power source, the lifting screw is driven to rotate and rise through the gear transmission assembly. With the help of the limit rod, the lifting plate can be lifted vertically in a directional manner, forming a transmission system that can steplessly adjust the height of the bogie without stopping the machine, which can effectively improve the efficiency of continuous operation.

[0067] By employing adjustable clamping components and a fixed reinforcement structure on the surface of the clamping blocks, adaptive clamping and anti-deviation positioning can be achieved for bogies of different sizes, improving versatility and eliminating the tedious steps of changing clamps.

[0068] The first and second motors, together with a dedicated fixed bracket and a lead screw end support bearing, form a matching structure that reduces vibration, prevents deviation, and ensures transmission meshing accuracy. This reduces transmission vibration, ensures meshing accuracy, makes the equipment run more stably, and extends its service life.
