Description

Technical Field

[0001] The present application relates to the field of diamond wire saws, and in particular to a bidirectional adjustable loop tensioning mechanism. Background Art

[0002] Brittle and hard materials such as silicon materials, sapphires, and ceramics are difficult to cut by ordinary processing methods because they are hard and brittle, and are prone to breakage and damage during the cutting process, resulting in material damage and reduced product yield. For the above problems, diamond wire saws have gradually emerged. When using a band saw for cutting and squaring, the cutting efficiency is high, but the cutting seam is wide and the cutting surface is uneven.

[0003] Chinese Patent No. CN112476790A discloses an annular superhard abrasive wire and its preparation method and preparation device. The preparation device includes a workbench, and a support assembly is arranged on the workbench. The support assembly is used to drive the annular core wire to move cyclically along its axial direction. The support assembly includes a plurality of drive rollers, and the drive rollers are driven by motors. The support assembly further includes a tensioning wheel, and the tensioning wheel can be connected to the workbench through an elastic telescopic member to ensure the tension of the annular core wire. Through the cooperation of the tensioning wheel and the elastic telescopic member, the tension of the annular core wire is guaranteed and it is applicable to annular core wires of different lengths.

[0004] Regarding the above technical solution, the inventor believes that when the length of the annular core wire required for production is relatively long, if only the elastic telescopic member is used to drive the tensioning wheel for one-way movement adjustment, the telescopic amount of the elastic telescopic member will be forced to be set relatively long, which is not conducive to the overall spatial layout of the equipment. Summary of the Utility Model

[0005] In order to meet the tension adjustment requirements of loops of different lengths, improve the limitations of the existing tensioning mechanism for one-way tension adjustment, and optimize the overall spatial layout, the present application provides a bidirectional adjustable loop tensioning mechanism.

[0006] A bidirectional adjustable loop tensioning mechanism provided by the present application adopts the following technical solution:

[0007] A bidirectional adjustable loop tensioning mechanism includes a workbench. A support assembly for driving an annular core wire to move cyclically along its axial direction is arranged on the workbench. The support assembly includes a driving wheel, a fixed-point driving wheel, and a vertical adjustment wheel that are arranged at intervals along the path direction of the annular core wire. The driving wheel is driven to rotate by a power source. The fixed-point driving wheel is rotatably arranged on the workbench. A transverse movement mechanism and a lifting mechanism are arranged on the workbench. The transverse movement mechanism is used to drive the driving wheel to move along the length direction of the workbench, and the lifting mechanism is used to drive the vertical adjustment wheel to move up and down.

[0008] By adopting the above technical solution, the lateral movement mechanism can drive the driving wheel to move horizontally, and the lifting mechanism can drive the vertical adjustment wheel to move up and down, so that the annular core wire can be stretched in two directions at the same time. Compared with the unidirectional tensioning adjustment, the present application can share the length difference of the annular core wire required for production through bidirectional tensioning adjustment, which not only meets the tensioning adjustment requirements of ring wires of different lengths, but also improves the limitation of the unidirectional movement distance being too long during unidirectional tensioning adjustment, which is conducive to optimizing the overall spatial layout.

[0009] Optionally, the transverse movement mechanism includes a transverse movement plate and a transverse movement assembly, the driving wheel is rotatably arranged on the transverse movement plate, the driving source is arranged on the transverse movement plate and connected to the driving wheel, the transverse movement plate is slidably connected to the workbench, and the transverse movement assembly is arranged on the workbench for driving the transverse movement plate to move along the length direction of the workbench.

[0010] By adopting the above technical solution, the lateral shifting assembly can drive the lateral shifting plate to move along the length direction of the workbench, thereby achieving the purpose of adjusting the lateral position of the driving wheel. The movement of the lateral shifting plate can drive the driving source and the driving wheel to move synchronously, ensuring that the driving wheel has a stable power supply.

[0011] Optionally, two transverse transmission wheels are provided on the transverse plate to force the annular core wire to pass through the driving wheel and the two transverse transmission wheels in an S shape.

[0012] The adoption of the above technical solution is conducive to increasing the contact area between the annular core wire and the driving wheel, reducing the possibility of the annular core wire slipping at the driving wheel, and thus improving the transmission stability and transmission efficiency of the driving wheel and the annular core wire.

[0013] Optionally, two fixed-point transmission wheels are provided, the vertical adjustment wheel is provided between the two fixed-point transmission wheels on the annular core wire path, and the vertical adjustment wheel is provided on the inner side of the annular core wire.

[0014] By adopting the above technical solution, because the two-way tensioning adjustment is used to tension and pull the annular core wire, the deviation range of the annular core wire in space is larger, and the spatial position of the positioning transmission wheel remains unchanged. Through the setting of two fixed-point transmission wheels, a transition and centering stabilization effect is played between the vertical adjustment wheel that can move up and down and the driving wheel that can move laterally, thereby reducing the possibility of the annular core wire slipping and ensuring the stability of the annular core wire adjustment.

[0015] Optionally, the lifting mechanism includes a slide rail vertically arranged on the workbench and a slider cooperatively arranged on the slide rail, and the vertical adjustment wheel is rotatably connected to the slider.

[0016] By adopting the above technical solution, the slider can slide up and down along the slide rail, thereby driving the vertical adjustment wheel to move up and down.

[0017] Optionally, a locking member is provided on the slider, and the locking member is used to lock the slider on the slide rail.

[0018] By adopting the above technical solution, the slider is locked by the locking member, so as to prevent the slider from sliding down under its own weight and thus affecting the tension of the annular core wire.

[0019] Optionally, a tension sensor is provided on the transverse movement plate, and the tension sensor is connected to one of the transverse movement transmission wheels.

[0020] By adopting the above technical solution, the tension sensor can detect the tension value of the annular core wire passing through the corresponding transverse movement transmission wheel, which is beneficial for the operator to control the tension of the arc-shaped core wire within a certain range, thereby ensuring the quality and stability of the production of the diamond annular wire.

[0021] Optionally, the transverse movement assembly is a lead screw sliding module arranged along the length direction of the workbench.

[0022] In summary, the present application includes at least one of the following beneficial technical effects:

[0023] 1. The transverse movement mechanism can drive the driving wheel to move horizontally, and the lifting mechanism can drive the vertical adjustment wheel to move up and down, so that the annular core wire can be stretched in two directions at the same time. Compared with the single-direction tension adjustment, the present application can allocate the length difference of the annular core wire required for production through the two-direction tension adjustment, which not only meets the tension adjustment requirements of different lengths of loop wires, but also improves the limitation of the too long single-direction movement distance during the single-direction tension adjustment, and is beneficial to optimizing the overall space layout.

[0024] 2. The slider is locked by the locking member, so as to prevent the slider from sliding down under its own weight and thus affecting the tension of the annular core wire.

[0025] 3. Through the setting of the locking member, the slider is locked by the locking member, so as to prevent the slider from sliding down under its own weight and thus affecting the tension of the annular core wire, which is beneficial to ensuring the stability of the tension of the annular core wire during the production process.

[0030] The following is combined with Figures 1 - 3 , further details of this application are given.

[0031] Example:

[0032] The embodiment of the present application discloses a bidirectional adjustable loop tensioning mechanism. A bidirectional adjustable loop tensioning mechanism comprises a workbench 1, on which is provided a support assembly 3 for driving a loop core wire 2 to circulate along its axial direction, the support assembly 3 comprising a driving wheel 31, a fixed-point transmission wheel 32 and a vertical adjustment wheel 33 arranged at intervals along the path direction of the loop core wire 2, the driving wheel 31 is driven to rotate by a power source 311, the fixed-point transmission wheel 32 is rotatably arranged on the workbench 1, a transverse mechanism 4 and a lifting mechanism 5 are provided on the workbench 1, the transverse mechanism 4 is used to drive the driving wheel 31 to move along the length direction of the workbench 1, and the lifting mechanism 5 is used to drive the vertical adjustment wheel 33 to move up and down.

[0033] When using the tensioning mechanism, the active wheel 31 can be driven to move horizontally through the transverse mechanism 4, and the vertical adjustment wheel 33 can be driven to move up and down through the lifting mechanism 5, so that the annular core wire 2 can be stretched in two directions at the same time. Compared with the unidirectional tensioning adjustment, the present application can distribute the length difference of the annular core wire 2 required for production through bidirectional tensioning adjustment, which not only meets the tensioning adjustment requirements of ring wires of different lengths, but also improves the limitation of the unidirectional movement distance being too long during unidirectional tensioning adjustment, which is conducive to optimizing the overall spatial layout.

[0034] Reference Figure 1 and Figure 3The transverse mechanism 4 includes a transverse plate 41 and a transverse assembly 42. The driving wheel 31 is rotatably arranged on one side of the transverse plate 41. The power source 311 is installed on the other side of the transverse plate 41 and the output end of the power source 311 is coaxially fixed with the driving wheel 31. The transverse plate 41 is slidably connected to the workbench 1. The transverse assembly 42 is arranged on the workbench 1. The transverse assembly 42 is a screw sliding module arranged along the length direction of the workbench 1, which is used to drive the transverse plate 41 to move along the length direction of the workbench 1. In this embodiment, the power source 311 can drive the transverse plate 41 to move along the length direction of the workbench 1 through the transverse assembly 42, thereby achieving the purpose of adjusting the lateral position of the driving wheel 31. And the movement of the transverse plate 41 can drive the power source 311 and the driving wheel 31 to move synchronously, ensuring that the driving wheel 31 has a stable power supply.

[0035] Reference Figures 1 - 2 Two transverse transmission wheels 411 are rotatably connected to the side wall of the transverse plate 41, which are used to force the annular core wire 2 to pass through the driving wheel 31 and the two transverse transmission wheels 411 in an S shape. In this way, the contact area between the annular core wire 2 and the driving wheel 31 is increased, and the possibility of the annular core wire 2 slipping at the driving wheel 31 is reduced, thereby improving the transmission stability and transmission efficiency of the driving wheel 31 and the annular core wire 2.

[0036] Reference Figure 1 There are two fixed-point transmission wheels 32, which are connected to the workbench 1 through a fixed frame 321, and the fixed frame 321 is fixed on the workbench 1. The two fixed-point transmission wheels 32 are rotatably connected to the fixed frame 321 respectively. The vertical adjustment wheel 33 is arranged between the two fixed-point transmission wheels 32 on the path of the annular core wire 2, and the vertical adjustment wheel 33 is arranged on the inner side of the annular core wire 2. Because the deviation range of the annular core wire 2 in space is larger when the two-way tensioning adjustment is performed on the tensioning and pulling of the annular core wire 2, the spatial position of the positioning transmission wheel remains unchanged, and the setting of the two fixed-point transmission wheels 32 plays a role of transition and centering stability between the vertical adjustment wheel 33 that can move up and down and the driving wheel 31 that can move laterally, reducing the possibility of the annular core wire 2 slipping and ensuring the stability of the adjustment of the annular core wire 2.

[0037] Reference Figure 1 The lifting mechanism 5 includes a slide rail 51 vertically fixed on the workbench 1 and a slider 52 matched with the slide rail 51, and the vertical adjustment wheel 33 is rotatably connected to the slider 52. In this way, the slider 52 can slide up and down along the slide rail 51, thereby driving the vertical adjustment wheel 33 to move up and down.

[0038] Reference Figure 1, a L-shaped connecting piece 521 is fixed on the slider 52, and a locking piece 522 is arranged on one side of the L-shaped connecting piece 521 for locking the slider 52 on the slide rail 51. In this embodiment, the locking piece 522 is a locking bolt, the locking piece 522 is threadedly connected to one side of the L-shaped connecting piece 521, and the tail of the locking piece 522 abuts against the adjacent side of the slide rail 51. The slider 52 is locked by the locking piece 522 to prevent the slider 52 from sliding down under its own weight, which may affect the tension of the annular core wire 2, and is beneficial to ensuring the stability of the tension of the annular core wire 2 during the production process.

[0039] Referring to Figures 2 - 3 , a tension sensor 412 is further installed on the transverse movement plate 41, and the tension sensor 412 is connected to one of the transverse movement transmission wheels 411. The tension value of the annular core wire 2 passing through the corresponding transverse movement transmission wheel 411 can be detected by the tension sensor 412, which is beneficial for the operator to control the tension of the arc-shaped core wire within a certain range, thereby ensuring the quality and stability of the production of the diamond annular wire.

[0040] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application shall be covered within the protection scope of the present application.
