Description

Technical Field

[0001] This utility model relates to the field of spoke testing technology, and in particular to a rapid double-head spoke cutting device. Background Technology

[0002] Wheel spokes typically consist of a spoke bar, a first spoke cap at one end of the spoke bar, and a second spoke cap at the other end of the spoke bar. The first spoke cap is used to connect with the rim, and the second spoke cap is used to connect with the hub.

[0003] The production of spoke rods usually involves first straightening the steel wire of the spoke rod and then cutting the spoke rod. For example, there is a Chinese utility patent published on June 20, 2017, which is a steel wire cutting device for spoke machines, with the publication number CN206263158U. However, the spoke length cut by this mechanism is not precise enough and can only be used as spoke blanks.

[0004] Furthermore, as exemplified by the Chinese invention patent CN119870327A published on April 25, 2025, which describes a spoke cutting device, this invention provides a technique for cutting spoke rods with more precise lengths from both ends of a spoke blank. However, in this spoke cutting device, the main body of the spoke fixture is a disc-shaped structure, with spoke fixing parts distributed circumferentially on the fixture body. This requires rotating the spoke fixture to complete the spoke loading, reducing loading efficiency. Additionally, the spoke fixing parts located at the top of the spoke fixture body are affected by gravity, which may cause spokes in the slots to fall out, reducing the number of spokes cut at one time. Furthermore, the spoke fixture needs to rotate to complete the spoke cutting sequentially, affecting the cutting speed.

[0005] Therefore, a spoke cutting machine with a high cutting speed is needed. Utility Model Content

[0006] To overcome the shortcomings of existing technologies, this utility model provides a fast double-head spoke cutting device to solve the current problems of slow spoke feeding and cutting speeds.

[0007] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a rapid double-head spoke cutting device, comprising: A spoke fixture includes an upper clamping assembly, a lower clamping assembly, and a first driving assembly for driving the upper clamping assembly toward or away from the lower clamping assembly, so that the upper clamping assembly can be switched to a clamping state that cooperates with the lower clamping assembly to clamp the spokes; the lower clamping assembly is provided with a plurality of parallel and spaced spoke placement slots, the length direction of the spoke placement slots is arranged along a first direction, and the plurality of spoke placement slots are distributed along a second direction; The cutting device includes a first frame and two cutting mechanisms mounted on the first frame along a first direction.

[0020] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model is further described below in conjunction with specific embodiments. However, the following embodiments are only preferred embodiments of this utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments in the implementation methods without creative effort are all within the protection scope of this utility model.

[0021] like Figures 1-4 As shown, this utility model provides a rapid double-head spoke cutting device, which consists of four main parts: spoke fixture 1, cutting device, multiple drive components and control screen 20. All components are integrated on the same workbench 19 to form a modular layout.

[0022] The spoke fixture 1 is used for clamping and positioning the spokes, the cutting device is used for synchronous cutting at both ends of the spokes, the drive assembly provides power to each moving part, and the control screen 20 realizes the setting of equipment parameters and operation control.

[0023] The spoke fixture 1 includes an upper clamping assembly 2, a lower clamping assembly 3, and a first driving assembly 4 for driving the upper clamping assembly 2 toward or away from the lower clamping assembly 3, so that the upper clamping assembly 2 can be switched to a clamping state that cooperates with the lower clamping assembly 3 to clamp the spokes; and the upper clamping assembly 2 can be switched to a state that separates from the lower clamping assembly 3 to properly remove the spokes.

[0024] The lower clamp assembly 3 is provided with a plurality of parallel and spaced spoke placement slots 18, the length direction of the spoke placement slots 18 is arranged along a first direction, and the plurality of spoke placement slots 18 are spaced apart along a second direction.

[0025] The cutting device includes a first frame 5 and two cutting mechanisms 6 mounted on the first frame 5 along a first direction. The cutting blade of the cutting device rotates about a first axis extending along the first direction. The two cutting mechanisms 6 are located on both sides of the spoke fixture 1.

[0026] This embodiment also includes a second drive assembly 7 for driving the spoke fixture 1 to move along a second direction, so that the cutting mechanism 6 sequentially cuts the spokes held by the spoke fixture 1. In other embodiments, the second drive assembly 7 may be used to drive the cutting mechanism 6 to move along a second direction.

[0027] Therefore, compared with the existing technology where the disc-type spoke fixture 1 needs to be rotated for feeding and has low cutting efficiency, this equipment avoids the time loss caused by fixture rotation by using the linearly arranged spoke placement grooves 18 and the double-head synchronous cutting structure, which significantly improves the feeding and cutting speed. At the same time, the design of double-head cutting, the second drive component 7 driving the cutting mechanism 6 and the spoke fixture 1 to move closer and further away along the second direction, realizes the sequential cutting of spokes, further improving the processing efficiency.

[0028] In this embodiment, all of the spoke placement slots 18 are located on the same horizontal plane. By limiting the angle of the spoke placement slots 18 to horizontal, it is ensured that the spokes remain stable within the placement slots 18, preventing the spokes from slipping or shifting position due to gravity.

[0029] In other embodiments, the plurality of spoke placement slots 18 may be located on the same plane at an angle of less than 10 degrees to the horizontal plane. Compared with the problem of spokes easily falling off due to the circumferential distribution of disc-type fixtures in the prior art, this design improves the fixing stability of spokes by arranging placement slots in a planar or slightly inclined manner, reduces processing interruptions caused by spokes falling off, and improves the reliability of continuous feeding; at the same time, the planar arrangement facilitates clamping with the upper clamping assembly 2, further improving the feeding efficiency and the efficiency of switching clamping states.

[0030] In this embodiment, the first drive assembly 4 includes a second frame 8, a first drive cylinder 9 mounted on the second frame 8, and a first mounting plate 10 located at the output end of the first drive cylinder 9. The upper clamping assembly 2 is fixedly connected to the bottom of the first mounting plate 10. The cylinder-driven first mounting plate 10 drives the upper clamping assembly 2 to quickly press down, cooperating with the lower clamping assembly 3 to complete the spoke clamping action. The reciprocating motion characteristics of the cylinder achieve automation and rapid response in the clamping process. Compared to traditional manual or complex transmission structure clamping methods, the cylinder-driven upper clamping assembly 2 has a fast response speed and stable clamping force, enabling rapid spoke clamping, shortening the preparation time for a single processing operation, and improving overall processing efficiency.

[0031] Please refer to Figure 1 The spoke fixture 1 also includes a clamping base 11, with a second mounting plate 12 on its top. The lower clamp assembly 3 is fixedly connected to the top of the second mounting plate 12. The clamping base 11 provides a stable mounting foundation for the lower clamp assembly 3, and the second mounting plate 12 serves as an intermediate connecting structure, facilitating the adjustment of the horizontal and vertical positions of the lower clamp assembly 3 and ensuring its alignment with the upper clamp assembly 2. The rigid support of the clamping base 11 improves the structural stability of the lower clamp assembly 3, avoids clamping deviations caused by equipment vibration, and ensures the consistency of spoke clamping and cutting accuracy.

[0032] Please refer to Figure 4 The upper clamping assembly 2 includes two first clamping plates 13 and a first guide rail unit 14 that can adjust the two first clamping plates 13 to move closer or further away along a first direction; the lower clamping assembly 3 includes two second clamping plates 15 and a second guide rail unit 16 that can adjust the two second clamping plates 15 to move closer or further away along a first direction; the cutting device further includes a third driving assembly 17, which is used to drive the cutting mechanism 6 to move along the first direction.

[0033] The first guide rail unit 14 and the second guide rail unit 16 respectively drive the two first clamping plates 13 and 15 to move closer or further away along the first direction, thereby adjusting the width of the clamping area in the cutting direction to accommodate spokes of different lengths. The third drive assembly 17 drives the cutting mechanism 6 to move along the first direction, adjusting the relative position of the cutting blade and the spokes to ensure the accuracy of the cutting position. Compared with the fixed-size spoke fixing part in the prior art, this design achieves compatible processing of spokes of different lengths through adjustable clamping plate spacing, expanding the applicability of the equipment. The adjustability of the cutting mechanism 6 ensures the accuracy of the cutting position and avoids cutting deviations caused by equipment assembly errors.

[0034] Furthermore, multiple spoke placement slots 18 are disposed on the top of the second clamping plate 15, and a buffer fastening layer is provided on the bottom of the first clamping plate 13. The spoke placement slots 18 are directly formed on the top of the second clamping plate 15, simplifying the structural design; the buffer fastening layer at the bottom of the first clamping plate 13 provides elastic pressure during clamping, preventing damage to the spokes due to rigid compression and enhancing the clamping tightness through elastic deformation. The buffer fastening layer reduces scratches or deformation on the spoke surface, improving the processing quality of the spokes; simultaneously, the elastic clamping avoids the problem of loose clamping caused by spoke length tolerances, further improving processing stability.

[0035] Preferably, the buffer fastening layer is a rubber material layer with a thickness of 1-8 mm. The rubber material has a certain elasticity and coefficient of friction. The thickness of 1-8 mm can provide sufficient buffering force while avoiding insufficient clamping force due to excessive thickness or buffering failure due to excessive thinness. Through the elastic buffering of the rubber layer, a "soft clamping" effect is achieved, which reduces damage to the spoke surface while ensuring that the spokes do not slip or fall off. This is suitable for spoke processing scenarios with high surface quality requirements.

[0036] Please refer to Figures 1 to 3 The system also includes a workbench 19 and a control screen 20. The spoke fixture 1, the cutting device, and the control screen 20 are all mounted on the workbench 19; the control screen 20 is signal-connected to the cutting device. The workbench 19 serves as an integrated platform for the equipment, facilitating the layout and operation of each component. The control screen 20 serves as a human-machine interface, enabling automated control of the cutting device via signal connections, such as adjusting the clamping distance, cutting speed, and starting / stopping. This design, through the integrated workbench 19 and intelligent control screen 20, achieves automated operation and parameterized control of the equipment, reducing the labor intensity of operators while improving the consistency of processing parameters and product qualification rate.

[0037] Furthermore, the spoke fixture 1 also includes a sliding guide rail 21 arranged along the second direction. The clamp fixing seat 11 is slidably disposed on the sliding guide rail 21. The moving end of the second drive component 7 is fixedly connected to the second frame 8 and the clamp fixing seat 11. This is used to drive the upper clamping component 2 and the lower clamping component 3 to move synchronously along the sliding guide rail 21. The sliding guide rail 21 provides a guide for the linear movement of the clamp fixing seat 11, ensuring its movement accuracy in the second direction, i.e., the spoke arrangement direction. The second drive component 7 simultaneously drives the fixed end of the second frame 8 and the clamp fixing seat 11 to move synchronously, avoiding the problem of the fixture needing to rotate for feeding in traditional designs. With the guidance of the linear guide rail, the movement of the clamp fixing seat 11 is more stable and precise, reducing positioning errors. The synchronous movement design eliminates the step of fixture rotation, realizing "linear" feeding of spokes, greatly improving the feeding speed, and eliminating the need to wait for the fixture to rotate into place in the prior art, thus solving the problem of low efficiency caused by rotating feeding in the prior art.

[0038] In a preferred embodiment, the spoke fixture 1 further includes a fourth drive assembly for driving the two first clamping plates 13 to move on the first guide rail unit 14, and a fifth drive assembly for driving the two second clamping plates 15 to move on the second guide rail unit 16. The first drive assembly 4, the second drive assembly 7, the third drive assembly 17, the fourth drive assembly, and the fifth drive assembly are respectively connected to the control screen 20 via signals. Through the coordinated control of multiple drive assemblies, the equipment can quickly adapt to the processing requirements of spokes of different specifications, such as different lengths and different clamping widths. No manual adjustment of the clamping positions is required, further improving the automation level and production efficiency of the equipment.

[0039] The operating procedure of this rapid double-head spoke cutting device is as follows: multiple spoke rods are sequentially placed into the spoke placement slots 18 of the lower clamp assembly 3. The spoke placement slots 18 are arranged in a straight line and can be filled manually in one go. Because the placement slots are designed to be horizontal or at a slight angle, the spoke rods will not slip due to gravity, and it is easy for automated feeding devices such as robotic arms to precisely dock. The control screen 20 activates the first drive assembly 4, causing the upper clamp assembly 2 to press down quickly. The rubber buffer fastening layer at the bottom of the first clamp plate 13 contacts the upper surface of the spoke rod, providing uniform clamping force through elastic deformation. The pressure can be adjusted via the screen to ensure that the spoke rod is firmly fixed and the surface is undamaged. The motor of the cutting device starts, and the cutting blade rotates to the set speed; at the same time, the third drive assembly 17 drives the cutting mechanism 6 to move along the first direction to the end position of the spoke rod, for example, 5mm away from the rod end. Subsequently, the second drive assembly 7 is activated, driving the cutting device to move along the second direction. The blades of the two cutting mechanisms 6 simultaneously cut both ends of the spoke rod, completing the cutting of two spokes in a single movement. After cutting, the blades return to their initial position, completing one cutting cycle. The second drive assembly 7 is activated again, driving the clamping fixture 11 to move along the second direction by the distance of one placement slot, moving the next set of spokes to the cutting station. The above clamping and cutting process is repeated until all spokes are processed.

[0040] In summary, the rapid dual-head spoke cutting equipment provided in this embodiment, through structural optimization and intelligent control, achieves fast spoke feeding speed, high-speed, precise, and universal cutting, effectively meeting the needs of large-scale wheel spoke production.

[0041] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
