DETAILED DESCRIPTION

[0047] In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the specific implementation methods of the present invention will be described below with reference to the accompanying drawings. Obviously, the drawings described below are only some embodiments of the present invention. For ordinary technicians in this field, they can also be understood as further technical solutions without creative work.

In this article, "one" not only means "only one", but also means "more than one", and "several" includes "two" and "more than two".

[0048] In this document, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0049] In addition, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0050] Reference Figure 1 to Figure 8, which is the first embodiment of the present invention, proposes a device for assembling railway fasteners, which is used to assemble an insulating nylon pad 110 with an upper iron pad 120 and a lower iron pad 130, including: a placement rack 210 is slidably arranged on a workbench 2, and the placement rack 210 is used to fix the upper iron pad 120 and the lower iron pad 130 and drive the upper iron pad 120 and the lower iron pad 130 to slide; a first telescopic member 220 has a plurality of members, which are arranged on the workbench 2, and the first telescopic member 220 is used to fix and drive the insulating nylon pad 110 to rise and fall, and the insulating nylon pad 110 enters the upper iron pad 120 and the lower iron pad 130 after descending.

[0051] In the present embodiment, when assembling, the upper iron pad 120 and the lower iron pad 130 are placed on the placement rack 210 after being buckled, and then the placement rack 210 is slid to a suitable position, and then the first telescopic member 220 moves to install the nylon pad that has not been installed. The placement rack 210 can fix the upper iron pad 120 and the lower iron pad 130 at the same time and drive them to slide, which facilitates the accurate adjustment of the position of the iron pad during the assembly process. When assembling the insulating nylon pad 110, the iron pad can be quickly moved to a suitable position, accurately docked with the insulating nylon pad 110, and the accuracy and efficiency of the assembly are improved. In contrast, if there is no such integrated placement rack 210, it will take more time and energy to position and move the upper and lower iron pads 130 respectively, and positioning deviation is prone to occur. The setting of multiple first telescopic members 220 is used to fix and drive the lifting of the insulating nylon pad 110, which realizes the automation degree of the insulating nylon pad 110 and the iron pad assembly process. The operator only needs to control the lifting and lowering action of the telescopic member to complete the assembly operation, which reduces the difficulty of assembly and shortens the time required for assembly. The cooperative work of the placement frame 210 and the first telescopic member 220 enables the insulating nylon pad 110 to be quickly and accurately positioned with the iron pad. The placement frame 210 accurately slides the iron pad to a predetermined position, and the first telescopic member 220 accurately lowers the insulating nylon pad 110 to a position corresponding to the iron pad.

[0052] As a further technical solution, the placement rack 210 has a plurality of mounting holes 211 , and further includes: a limiting platform 212 detachably disposed on the placement rack 210 , and the limiting platform 212 has a plurality of fixing holes 213 corresponding to the mounting holes 211 .

[0053] In the present embodiment, a plurality of mounting holes 211 are arranged on the placing rack 210, and the limiting platform 212 is detachable and has fixing holes 213 corresponding to the mounting holes 211 thereon, and this design enables the device to adapt to upper iron pads 120 and lower iron pads 130 of different specifications. By adjusting the position of the limiting platform 212 on the placing rack 210, the fixing is performed using the mounting holes 211 and fixing holes 213 at different positions, and the fixing range and method of the placing rack 210 to the iron pad can be changed. In the production of railway fasteners, there may be iron pads of various models and specifications that need to be assembled. This design can quickly switch the assembly modes of different specifications on the same device, without replacing the entire placing rack 210 or the device, thereby improving the versatility and flexibility of the device and reducing the production cost. If there is no such adjustable limiting platform 212 design, different special placing racks 210 may need to be equipped for iron pads of different specifications, which not only increases the equipment cost, but also takes up more storage space. The cooperation of the limiting platform 212 and the placing rack 210 can accurately limit the iron pad. When the limiting platform 212 is fixed on the placement frame 210 through the fixing hole 213 and the mounting hole 211, the boundary formed by it can limit the movement range of the iron pad in the plane, ensuring that the iron pad always remains in the correct position during the assembly process.

[0054] As a further technical solution, it also includes: a second telescopic member 230 is arranged on the workbench 2, the second telescopic member 230 is located above the limit platform 212, and the second telescopic member 230 presses or cancels the pressing of the upper iron pad 120 and the lower iron pad 130 after actuation, and the second telescopic member 230 is used to limit the position of the upper iron pad 120 and the lower iron pad 130; there are several third telescopic members 240, which are arranged on the workbench 2, and the third telescopic members 240 are located on the left and right sides of the placement rack 210, and several third telescopic members 240 form a clamping space, and the clamping space is used to clamp or release the upper iron pad 120 and the lower iron pad 130 located on the placement rack 210, and the third telescopic member 240 is used to limit and align the position of the upper iron pad 120 and the lower iron pad 130.

[0055] In the present embodiment, the second telescopic member 230 is arranged on the workbench 2 to limit the up and down movement of the upper iron pad 120 and the lower iron pad 130. In the assembly process of the railway fastener, especially when the insulating nylon pad 110 is assembled with the iron pad, it is necessary to ensure that the iron pad maintains a stable position to prevent it from moving up and down. If the iron pad moves up and down during the assembly process, it may cause the assembly between the insulating nylon pad 110 and the iron pad to be not firm, affecting the overall structural stability of the fastener. The second telescopic member 230 can be used as a further technical solution. The height position is suitable to improve the adaptability of the device to workpieces of different specifications. Several third telescopic members 240 are located on the left and right sides of the placement rack 210 to limit and correct the position of the upper iron pad 120 and the lower iron pad 130. In actual production, when the iron pad is placed on the placement rack 210, the left and right position offset may occur. Even if the placement rack 210 itself has a certain positioning function, it may still produce a slight deviation during the handling or placement process. The third telescopic member 240 can apply appropriate pressure to the iron pad from the left and right sides to correct it to the accurate position. The correction function of the third telescopic member 240 helps to ensure the consistency of assembly. Since it can accurately correct the left and right positions of each iron pad, the position difference of different iron pads during assembly is extremely small, thereby ensuring that each assembled railway fastener has similar structure and performance. In a railway track system, the consistency of a large number of fasteners is crucial to the overall stability and safety of the track. If there are large position differences between fasteners, it may cause uneven force on the track, affect the stability of the train, and increase the track maintenance cost and safety risks. The presence of the third telescopic member 240 effectively avoids these problems and improves the overall quality of railway fasteners.

[0056] As a further technical solution, one side of the placement rack 210 has a plurality of positioning holes 214, and also includes: a plurality of adjustment seats 250, which are arranged on the workbench 2; an adjustment rod 260 is slidably arranged on the adjustment seat 250, and the adjustment rod 260 enters or leaves the positioning hole 214 after sliding, and the adjustment rod 260 is used to limit the sliding of the placement rack 210.

[0057] In this embodiment, a plurality of positioning holes 214 on one side of the placement rack 210 cooperate with the adjustment rod 260 slidably arranged on the adjustment seat 250, so as to realize the accurate positioning of the sliding position of the placement rack 210 on the workbench 2. During the assembly process of the railway fasteners, the placement rack 210 needs to accurately move the upper iron pad 120 and the lower iron pad 130 to the position for assembly with the insulating nylon pad 110. After the adjustment rod 260 enters the positioning hole 214, it can limit the sliding of the placement rack 210, ensure that it maintains a stable position during assembly, and avoid the assembly dislocation of the iron pad and the insulating nylon pad 110 due to the accidental movement of the placement rack 210. The provision of multiple positioning holes 214 provides more positioning options, which can adapt to the assembly requirements of railway fasteners with different assembly processes or different specifications.

[0058] As a further technical solution, it also includes: there are several storage barrels 3, which are arranged on the workbench 2, and the storage barrels 3 are used to store several unassembled insulating nylon pads 110; the material picking piece 4 is arranged on the first telescopic piece 220, and the material picking piece 4 has a temporary storage space 410, and the temporary storage space 410 is used to store the insulating nylon pads 110, and the material picking piece 4 also has a material inlet 420 and a material outlet 430 connected to the temporary storage space 410. After the material picking piece 4 descends, the material inlet 420 abuts against the storage barrel 3, and the material will enter the material picking piece 4 from the storage barrel 3 through the material inlet 420; the feeding plate 440 is slidably arranged in the temporary storage space 410, and the feeding plate 440 is used to push the insulating nylon pad 110 entering the temporary storage space 410 from the material inlet 420 to the material outlet 430; there are several blocking blocks 450, which are arranged in the temporary storage space 410, and the blocking blocks 450 are used to limit the position of the insulating nylon pad 110.

[0059] In this embodiment, a plurality of storage barrels 3 are arranged on the workbench 2 for storing unassembled insulating nylon pads 110, thereby realizing centralized storage and management of materials. In the process of assembling railway fasteners, a large number of insulating nylon pads 110 are required. The storage barrel 3 can reserve a certain amount of materials in advance, thereby reducing the time for frequent replenishment of materials, and realizing one-by-one discharging of materials through its own screw structure, thereby improving production efficiency. The temporary storage space 410 in the material taking part 4 is in contact with the storage barrel 3 through the material inlet 420 to take materials, thereby realizing an automated material taking process. The material taking part 4 descends under the drive of the first telescopic part 220. When the material inlet 420 contacts the storage barrel 3, an insulating nylon pad 110 can be accurately obtained. Compared with manual material taking, this automated material taking method improves the accuracy and speed of material taking. The feeding plate 440 slides in the temporary storage space 410, and pushes the insulating nylon pad 110 entering the temporary storage space 410 from the material inlet 420 to the material outlet 430, thereby ensuring the orderly transportation of materials in the material taking part 4. During the material retrieval process, the insulating nylon pad 110 may be offset or stuck in the temporary storage space 410. The pushing action of the feed plate 440 can ensure that the nylon pad reaches the material outlet 430 smoothly for subsequent assembly operations. Several blocking blocks 450 are set in the temporary storage space 410 to limit the position of the insulating nylon pad 110 and ensure the stability and accuracy of the material in the material retrieval part 4. The blocking blocks 450 can prevent the insulating nylon pad 110 from excessive shaking or rolling in the temporary storage space 410, so that it always remains in the correct position, which is convenient for the feeding plate 440 to push and discharge from the material outlet 430.

[0060] As a further technical solution, it also includes: a first elastic member 460 is located in the temporary storage space 410, and its two ends are respectively arranged on the feeding plate 440 and the storage barrel 3, and the first elastic member 460 is used to provide the feeding plate 440 with a force to push the material toward the material outlet 430; the two ends of the connecting line 470 are respectively arranged on the baffle plate and the workbench 2, and after the storage barrel 3 descends, the connecting line 470 is used to provide a force for the feeding plate 440 to move away from the material outlet 430.

[0061] In this embodiment, during each feeding process, after the feeding plate 440 pushes the insulating nylon pad 110 to the material outlet 430, the elastic force of the first elastic member 460 provides the feeding plate 440 with the force to push the material to the material outlet 430. After the material is pushed to the specified position, with the action of the first telescopic member 220, the material taking member 4 will drop and abut against the upper iron pad 120 and the lower iron pad 130. At this time, the first telescopic member 220 will continue to drop and then abut against the insulating nylon sleeve, and finally the insulating nylon sleeve will be pushed out from the material outlet 430 into the position where the upper iron pad 120 and the lower iron pad 130 need to be installed. The two ends of the connecting line 470 are respectively connected to the baffle plate and the workbench 2. When the storage barrel 3 drops to take the material, the connecting line 470 provides the feeding plate 440 with the force to stay away from the material outlet 430. This design cleverly realizes the control of the position of the feeding plate 440 during the material taking process. When the storage barrel 3 descends and docks with the material taking part 4 to take the material, the connecting line 470 pulls the feeding plate 440 away from the material outlet 430, making room for the new insulating nylon pad 110 to enter the temporary storage space 410, ensuring the smooth progress of the material taking process. The coordinated work of the first elastic member 460 and the connecting line 470 reduces the risk of mechanical failure. Since they respectively control the movement of the feeding plate 440 at different stages, the use of complex mechanical transmission structures or too many electronic control components is avoided. Complex mechanical transmission structures are prone to problems such as wear and stagnation, and electronic control components may be affected by electromagnetic interference, power supply fluctuations, etc. The device realizes the motion control of the feeding plate 440 through simple elastic members and connecting lines 470, reducing the influence of these factors on the stability of the device operation.

[0062] As a further technical solution, it also includes: a plurality of one-way rollers 480 are rotatably arranged on the side wall of the material inlet 420 , and the plurality of one-way rollers 480 are used to ensure that the insulating nylon pad 110 enters the temporary storage space 410 from the material inlet 420 .

[0063] In this embodiment, a plurality of one-way rollers 480 are rotatably arranged on the side wall of the material inlet 420, providing a guiding and auxiliary pushing function for the insulating nylon pad 110 to enter the temporary storage space 410. During the material taking process, when the insulating nylon pad 110 moves from the storage barrel 3 to the material inlet 420 of the material taking part 4, the one-way roller 480 can rotate with the movement of the nylon pad, reducing the friction between the nylon pad and the side wall of the material inlet 420, so that the nylon pad can enter the temporary storage space 410 more smoothly. The rotation direction design of the one-way roller 480 ensures that only the insulating nylon pad 110 can enter the temporary storage space 410 from the material inlet 420, and will not flow out in the opposite direction. This feature effectively prevents the problem of material backflow that may occur during the material taking process. Due to the presence of the one-way roller 480, the insulating nylon pad 110 contacts and rolls with the one-way roller 480 when entering the material inlet 420, instead of directly rubbing against the side wall of the material inlet 420. This greatly reduces the wear of the side wall of the material inlet 420.

[0064] As a further technical solution, it also includes: there are a plurality of guide wheels 490, which are respectively arranged on the storage barrel 3 and the workbench 2, and the guide wheels 490 are used to guide the connecting line 470 to change direction.

[0065] In this embodiment, since the guide wheel 490 optimizes the movement of the connecting line 470, the motion control accuracy and response speed of the feeding plate 440 and other components are improved, and the assembly efficiency is finally improved. In the assembly of railway fasteners, the efficient operation of each link has an important impact on the overall assembly efficiency. When the feeding plate 440 can move accurately and quickly in the temporary storage space 410, the transportation and assembly process of the insulating nylon pad 110 will be smoother. The guide wheel 490 reduces the impact of the failure of the connecting line 470 on the assembly efficiency. If the connecting line 470 has problems such as entanglement and jamming, it will cause the device to shut down for maintenance, seriously affecting the production progress. The reasonable use of the guide wheel 490 can reduce the probability of these failures. Even if some minor problems occur, it is convenient for maintenance personnel to quickly check and solve them, shortening the equipment downtime, and increasing the effective operation time of the equipment, thereby improving the assembly efficiency.

[0066] As a further technical solution, it also includes: a guide rod 491 is arranged in the temporary storage space 410, and a connecting line 470 passes through the guide rod 491 and is connected to the feeding plate 440.

[0067] In this embodiment, the guide rod 491 is disposed in the temporary storage space 410, and the connecting wire 470 passes through the guide rod 491 and is connected to the feed plate 440, providing stable support and guidance for the connection between the connecting wire 470 and the feed plate 440. In the railway fastener assembly device, the connecting wire 470 needs to accurately transmit force to the feed plate 440 to control its movement in the temporary storage space 410. The guide rod 491 can prevent the connecting wire 470 from shaking or deflecting during the force transmission process, ensuring that the force can accurately act on the feed plate 440.

[0068] As a further technical solution, it also includes: one end of the anti-return plate 5 is hinged to the material picking part 4, the anti-return plate 5 is located in the temporary storage space 410 and between the material inlet 420 and the material outlet 430, and the anti-return plate 5 is used to prevent the insulating nylon pad 110 in the temporary storage space 410 from returning; the two ends of the second elastic member 510 are respectively arranged on the anti-return plate 5 and the adjustment seat 250, and the second elastic member 510 is used to provide a force to lift the anti-return plate 5.

[0069] In this embodiment, one end of the anti-return plate 5 is hinged to the material taking member 4 and is located in the temporary storage space 410 between the material inlet 420 and the material outlet 430. Its main function is to prevent the insulating nylon pad 110 in the temporary storage space 410 from returning. During the assembly of the railway fastener, when the feeding plate 440 pushes the insulating nylon pad 110 from the material inlet 420 to the material outlet 430, the anti-return plate 5 can prevent the nylon pad from returning to the material inlet 420 when it is subjected to a reverse force. The second elastic member 510 can slightly lift the anti-return plate 5, thereby ensuring that the anti-return plate 5 plays a role in preventing reverse movement.

[0070] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
