Description

Technical Field

[0001] This utility model belongs to the field of wrist arm assembly, and specifically relates to a load-bearing cable seat clamping device for assembling a wrist arm. Background Technology

[0002] In the field of railway catenary cantilever assembly, the clamping and pre-assembly processes of the catenary support seat require high assembly efficiency and positioning accuracy. In existing technologies, the clamping of the catenary support seat mostly relies on manual adjustment or fixed clamps, which presents the following problems:

[0003] First, traditional clamps are difficult to adapt to the rapid switching of different specifications of load-bearing cable seats, and lack versatility. Second, manual operation is prone to clamping position deviation, affecting the accuracy of subsequent cantilever arm insertion. Third, the fixing and positioning efficiency of the load-bearing cable seats during the pre-assembly process is low, making it difficult to meet the needs of mass production.

[0004] Based on this, this utility model proposes a load-bearing cable holder clamping device for assembling a cantilever arm that can achieve multi-specification compatibility, automated clamping, and precise positioning. Utility Model Content

[0005] To address the aforementioned problems in the existing technology, namely, its inability to adapt to various specifications, clamping position deviations, and low positioning efficiency, this utility model provides a load-bearing cable seat clamping device for assembling a cantilever arm. The device includes:

[0006] The rack includes a load-bearing cable seat mounting assembly and an adjustable support assembly;

[0007] The load-bearing cable seat mounting assembly array is distributed on the adjustable support assembly, and the adjustable support assembly is slidably connected to the ground; the load-bearing cable seat mounting assembly is a telescopic assembly, and a load-bearing cable seat is sleeved on the telescopic end of the telescopic assembly;

[0008] A conveying device is used to push the telescopic end to extend and retract, and after the clamping end is arranged inside the load-bearing cable seat, the clamping end is opened to achieve clamping and fixing of the load-bearing cable seat;

[0009] Multiple pre-assembled clamping devices are slidably connected to the pre-assembly station. The conveying device clamps the load-bearing cable seat between two pre-assembled clamping devices, moves the two pre-assembled clamping devices in opposite directions until the load-bearing cable seat is clamped, and inserts the cantilever arm into the inside of the load-bearing cable seat at the pre-assembly station.

[0010] Furthermore, the telescopic component also includes a fixed end, which is evenly distributed in multiple groups along the height direction of the adjustable support component, and the fixed end is equipped with a telescopic end that can move along it.

[0011] Furthermore, the distance between each pair of adjacent fixed ends is set based on the different height dimensions of the load-bearing cable seats.

[0012] Furthermore, the load-bearing cable seat, which is fitted onto the telescopic end and is close to the adjustable support assembly, overlaps with the surface of the adjustable support assembly.

[0013] Furthermore, among the multiple load-bearing cable seats fitted on the telescopic end, the surfaces of each pair of adjacent load-bearing cable seats are in contact.

[0014] Furthermore, the pre-assembled clamping device is used to clamp the surface of the load-bearing cable seat, excluding the internal hollow portion.

[0015] Furthermore, the pre-assembled clamping device is U-shaped to match the shape of the load-bearing cable seat.

[0016] Furthermore, the diameter of the telescopic end is less than or equal to the diameter of the circle of the hollow part inside the load-bearing cable seat.

[0017] Furthermore, the handling device includes a six-axis robotic arm.

[0018] Furthermore, at least two sets of the material rack are arranged along the direction of movement of the pre-assembled clamping device, and the conveying device is capable of moving along the direction of movement of the pre-assembled clamping device.

[0019] The beneficial effects of this utility model are:

[0020] The array distribution design of adjustable support components and load-bearing cable seat installation components enables multi-station synchronous operation, improves batch assembly efficiency, and adapts to the installation requirements of load-bearing cable seats of different specifications.

[0021] This utility model uses a handling device to push the telescopic end to clamp from inside the load-bearing cable seat, which is different from the traditional external clamping method. It avoids the interference of external clamps on the load-bearing cable seat structure, ensures the fixed stability of the load-bearing cable seat in the pre-assembly station, and reserves external operating space for the subsequent insertion of the cantilever arm, ensuring the continuity of the pre-assembly process.

[0022] The telescopic end of the telescopic component, combined with the automatic pushing function of the conveying device, can precisely control the opening and closing of the clamping end, reduce manual intervention, and ensure the stability and consistency of the load-bearing cable seat clamping.

[0023] The sliding fit between the pre-assembly clamping device and the pre-assembly station, combined with the opposing moving clamping method, can quickly complete the positioning and fixing of the load-bearing cable seat, avoid positional displacement when the cantilever arm is inserted, and improve the pre-assembly accuracy and efficiency.

[0024] The overall device simplifies the operation process and reduces assembly complexity through the coordinated use of modular design (such as adjustable supports, telescopic components, and handling devices), making it suitable for standardized assembly line operations.

[0030] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the scope of the invention. Furthermore, it should be noted that, for ease of description, only the parts relevant to the invention are shown in the accompanying drawings.

[0031] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0032] like Figures 1-4 As shown, see details. Figure 1 and Figure 3 This utility model provides a load-bearing cable seat clamping device for assembling a cantilever arm, the device comprising:

[0033] The material rack 1 includes a load-bearing cable seat mounting assembly 11 and an adjustable support assembly 12;

[0034] The load-bearing cable seat mounting components 11 are arrayed on the adjustable support components 12, and the adjustable support components 12 are slidably connected to the ground; the load-bearing cable seat mounting components 11 are telescopic components, and load-bearing cable seats are sleeved on the telescopic end 111 of the telescopic components.

[0035] The conveying device 2 is used to push the telescopic end 111 to extend and retract. After the clamping end 21 is arranged inside the load-bearing cable seat, the clamping end 21 is opened to achieve clamping and fixing of the load-bearing cable seat.

[0036] Multiple pre-assembled clamping devices 3 are slidably connected to the pre-assembled station 4. The conveying device 2 clamps the load-bearing cable seat between two pre-assembled clamping devices 3, moves the two pre-assembled clamping devices 3 towards each other until the load-bearing cable seat is clamped, and inserts the cantilever arm into the inside of the load-bearing cable seat at the pre-assembled station.

[0037] In this embodiment, the handling device 2 uses a six-axis manipulator. When installing the load-bearing cable seats, multiple load-bearing cable seats are fitted on the telescopic end 111. The load-bearing cable seats fitted on the telescopic end 111 near the adjustable support component 12 overlap with the surface of the adjustable support component 12. This arrangement ensures that when the handling device 2 pushes the telescopic end 111, the load-bearing cable seats will not move, because every two adjacent load-bearing cable seats are tightly attached together, and the load-bearing cable seat farthest from the handling device 2 is also tightly attached to the adjustable support component 12.

[0038] In use, firstly, drive the clamping end 21 of the conveying device 2 to rise to a position flush with the center of the telescopic end 111, push the telescopic end 111 to extend and retract, and place the clamping end 21 in the inner ring of the load-bearing cable seat. At this time, open the clamping end 21 to achieve fixation. After clamping, rotate the conveying device 2 to transfer it to the vision inspection system 5 fixed on the side of the material rack 1 for posture detection. After passing the inspection, transfer it to the pre-assembly station 4, use two pre-assembly clamping devices 3 to fix the load-bearing cable seat, and wait for the cantilever arm to be inserted.

[0039] The adjustable support assembly 12 is slidably connected to the ground. In this embodiment, a combination structure of nut screw and guide rail is selected, which is the prior art and will not be described in detail here. In addition, those skilled in the art can also choose any device that can achieve movement, such as pneumatic, hydraulic, linear motor, etc., which are not specifically limited here.

[0040] After each clamping, the adjustable support assembly 12 moves a set distance closer to the transport device 2 to prevent the rear load-bearing cable seat from being too far from the transport device 2 and thus exceeding the working range of the transport device 2.

[0041] For further explanation of this utility model, see [link to relevant documentation]. Figure 2 The telescopic component also includes a fixed end 112, which is evenly distributed in multiple arrays along the height direction of the adjustable support component 12, and a telescopic end 111 that can move along the fixed end 112 is disposed therein.

[0042] The fixed end 112 is a sleeve that provides support for the telescopic end 111.

[0043] In this embodiment, a return spring can be provided between the fixed end 112 and the telescopic end 111 so that the telescopic end 111 can return to its original position each time it is pushed back. The distance that the clamping end 21 pushes the telescopic end 111 each time is increased by the background program. The increasing distance is equal to the thickness of the load-bearing cable seat. With the above design, after all the load-bearing cable seats are assembled, the telescopic end 111 does not need to be manually pulled out, and the load-bearing cable seat can be easily put back on the telescopic end 111.

[0044] As a further explanation of this utility model, the distance between each two adjacent fixed ends 112 is set based on the different height dimensions of the load-bearing cable seats.

[0045] The present invention, through the above-described design, can adapt to load-bearing cable seats of different sizes, thereby improving its adaptability.

[0046] As a further explanation of this utility model, the pre-assembled clamping device 3 is used to clamp the surface of the load-bearing cable seat excluding the internal hollow position.

[0047] This invention enables the load-bearing cable seat to be fixed while also allowing the wrist arm to be smoothly inserted.

[0048] For further explanation of this utility model, see [link to relevant documentation]. Figure 4 The pre-fitted clamping device 3 is U-shaped to match the shape of the load-bearing cable seat.

[0049] The present invention enables the pre-assembled clamping device 3 to fit more closely to the load-bearing cable seat, thereby achieving stable clamping.

[0050] The diameter of the telescopic end 111 is less than or equal to the diameter of the circle of the hollow part inside the load-bearing cable seat.

[0051] The present invention enables the load-bearing cable seat to be smoothly fitted onto the telescopic end 111 through the above-described contents, preferably with a clearance fit.

[0052] See Figure 1 To improve assembly efficiency, in this embodiment, at least two sets of the material rack 1 are arranged along the direction of movement of the pre-assembly clamping device 3, and the conveying device 2 can move along the direction of movement of the pre-assembly clamping device 3.
