Description

Technical Field

[0001] The present application relates to the field of diamond wire saws, and in particular to a guiding mechanism for braiding diamond annular wires. 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 cut width is large and the cutting surface is uneven.

[0003] Chinese Patent with publication number CN112476790A discloses an annular superhard abrasive wire and its preparation method and preparation device. The wire winding mechanism and winding sizing mechanism in the preparation device form a strand winding module, realizing the automatic winding of several turns of strands on the annular core wire.

[0004] Regarding the above technical solution, the inventor believes that when the target preparation length of the diamond annular wire is relatively long, the annular core wire is prone to shaking during the winding of the strands, thereby affecting the braiding quality of the diamond annular wire. Utility Model Content

[0005] In order to improve the braiding quality of the diamond annular wire, the present application provides a guiding mechanism for braiding diamond annular wires.

[0006] The guiding mechanism for braiding diamond annular wires provided by the present application adopts the following technical solution:

[0007] A guiding mechanism for braiding diamond annular wires includes a workbench. A support assembly for driving the annular core wire to move axially in a cycle is provided on the workbench. A strand winding module for winding the strands around the annular core wire is provided on the workbench. A wire guiding module is further provided on the workbench. The wire guiding module is located at the rear end of the strand winding module. A wire guiding eye hole for the annular core wire to pass through is provided on the wire guiding module. The wire guiding module is divided into a detachable upper wire guiding part and a lower wire guiding part along the horizontal radial center line of the wire guiding eye hole.

[0008] By adopting the above technical solution, when braiding the diamond ring wire, first pass the strip-shaped wire through the wire eye holes on the support assembly, the strand winding module and the wire guiding module. Then, according to the required length for production, spot-weld the starting end of the strip-shaped wire to a certain position on the wire to form a ring-shaped core wire. Finally, wind the remaining strand part of the wire onto the outside of the ring-shaped core wire through the strand winding module to realize the automatic braiding of the diamond ring wire. Through the setting of the wire guiding module and the wire eye holes, according to the set aperture size of the wire eye holes, the radial deviation amplitude of the ring-shaped core wire can be effectively controlled, which is convenient for reducing the shaking amplitude during the braiding process of the diamond ring wire, and thus improving the braiding quality of the diamond ring wire. And when the diamond ring wire is finally braided, the wire guiding module can be disassembled into upper and lower parts, which is convenient for taking out the diamond ring wire from the wire eye holes.

[0009] Optionally, limiting side plates are provided on the left and right sides of the upper wire part. A upper fixing block is detachably connected between the two limiting side plates. The upper fixing block is provided with a pressing assembly for pressing the upper wire part against the lower wire part.

[0010] By adopting the above technical solution, the upper wire part can be pressed against the lower wire part through the pressing assembly, and the left and right sides of the upper wire part can be limited through the limiting side plates. On the one hand, it is convenient for the connection between the upper fixing block and the limiting side plates. On the other hand, it can reduce the possibility of dislocation between the upper wire part and the lower wire part, which is convenient for improving the assembly efficiency of the wire guiding module.

[0011] Optionally, the pressing assembly includes a lower movable block and an elastic member. The lower movable block is slidably connected to the upper fixing block in the vertical direction. A receiving groove for accommodating the lower movable block is provided at the bottom end of the upper fixing block. The elastic member is arranged between the bottom wall of the receiving groove and the lower movable block. The lower end of the lower movable block is connected to the upper wire part. When the elastic member is in the natural state, the lower movable block partially or completely extends out of the receiving groove.

[0012] By adopting the above technical solution, when the elastic member is compressed, the lower movable block can gradually retract into the receiving groove, so as to facilitate the separation of the upper wire part and the lower wire part. When the external force is removed, the elastic member resets, and the upper wire part can be pressed and attached to the upper end of the lower wire part to realize the splicing of the upper wire part and the lower wire part.

[0013] Optionally, a movable rod is provided at the top of the lower movable block. The upper fixing block is provided with a through hole for the vertical penetration of the movable rod. The through hole is communicated with the receiving groove. The elastic member is arranged outside the movable rod. A pulling grip part is provided at the end of the movable rod away from the lower movable block.

[0014] By adopting the above technical solution, pulling the pulling and holding part can drive the movable rod to move upward, thereby driving the lower movable block to gradually retract into the accommodating groove, and further separating the upper wire part from the lower wire part.

[0015] Optionally, step portions are provided on the left and right sides of the upper fixing block, and constricted portions matching the step portions are respectively provided on the opposite sides of the two limiting side plates. The constricted portions and the adjacent step portions are connected by fasteners.

[0016] By adopting the above technical solution, the step portion and the constricted portion are cooperatively connected, which is convenient for inserting the upper fixing block from the front and rear ends of the two limiting side plates, and is convenient for the positioning and installation of the upper fixing block.

[0017] Optionally, a jack for inserting a pin is provided on the movable rod, and a vertically arranged waist-shaped hole corresponding to the jack is provided on the upper fixing block.

[0018] By adopting the above technical solution, after inserting a conventional pin into the jack through the waist-shaped hole, the upper and lower limit positions of the pin are defined by the setting of the waist-shaped hole, so as to facilitate the limitation of the upper and lower limit positions of the movable rod, and reduce the possibility of the separation of the movable rod and the upper fixing block when disassembling the wire module.

[0019] Optionally, a threaded section is provided at one end of the movable rod away from the lower movable block, and a threaded hole adapted to the threaded section is provided on the pulling and holding part.

[0020] By adopting the above technical solution, the pulling and holding part and the movable rod are detachably connected, which is convenient for the installation of the movable rod.

[0021] In summary, the present application includes at least one of the following beneficial technical effects:

[0022] 1. Through the setting of the avoidance groove, after being used for a period of time, the interlocking rod may be deformed due to various possible reasons. When the interlocking rod moves, the avoidance groove on the opening half shaft can avoid the interlocking rod, reducing the possibility of the opening half shaft interfering with the movement of the interlocking rod, thereby reducing the occurrence of jamming phenomena and facilitating the smooth use of the circuit breaker.

[0023] 2. Through the setting of the bending part, when the interlocking rod moves, the bending part on the interlocking rod can avoid the support rod, reducing the possibility of friction between the support rod and the interlocking rod, thereby reducing the occurrence of jamming phenomena. At the same time, the wear of the interlocking rod and the support rod is reduced, which is beneficial to improving the service life of the circuit breaker.

[0024] 3. By providing an installation opening, an ear, and a fastener, when installing the drive cam, the fastener can be loosened, the spline groove can be aligned with the spline shaft, and the drive cam can be installed on the spline shaft along the axial direction of the spline shaft. Finally, the fastener is tightened to reduce the possibility of axial displacement of the drive cam during use, facilitating the installation and normal use of the drive cam.

Detailed Description of the Embodiment

[0030] The following will further describe the present application in detail Figures 1-4 in conjunction with the attached drawings.

[0031] An embodiment of the present application discloses a guiding mechanism for diamond ring wire braiding. Referring to Figure 1 , a guiding mechanism for diamond ring wire braiding includes a workbench 1, and a support component 2 for driving a ring-shaped core wire to move cyclically along its axial direction is provided on the workbench 1. The support component 2 includes a plurality of driving wheels 21 rotatably arranged on the workbench 1, and one of the driving wheels 21 is driven to rotate by a motor. The support component 2 further includes a tensioning wheel 22, and the tensioning wheel 22 is connected to the workbench 1 through a linear module 11. The linear module 11 can drive the tensioning wheel 22 to move linearly, thereby ensuring the tension of the ring-shaped core wire and being applicable to ring-shaped core wires of different lengths.

[0032] Refer to Figures 1-2 , on the workbench 1, there is a strand winding module 3 for winding strands around the annular core wire. To reduce the shaking amplitude of the annular core wire when winding the strands, which may affect the braiding quality of the diamond annular wire, a wire guiding module 4 is installed on the workbench 1. The wire guiding module 4 is fixed to the workbench 1 through the chassis 12. A wire guiding hole 43 for the annular core wire to pass through is provided on the wire guiding module 4, and the wire guiding module 4 is divided into a detachable upper wire guiding part 41 and a lower wire guiding part 42 along the horizontal radial center line of the wire guiding hole 43.

[0033] When braiding the diamond annular wire, first pass the long strip-shaped wire through the support assembly 2, the strand winding module 3 and the wire guiding hole 43 on the wire guiding module 4. Then, according to the required length for production, spot-weld the starting end of the long strip-shaped wire to a certain position on the wire to form an annular core wire. Finally, wind the remaining strand part of the wire around the outside of the annular core wire through the strand winding module 3 to realize the automatic braiding of the diamond annular wire. Through the setting of the wire guiding module 4 and the wire guiding hole 43, according to the set aperture size of the wire guiding hole 43, the radial deviation amplitude of the annular core wire can be effectively controlled, which is convenient for reducing the shaking amplitude during the braiding process of the diamond annular wire, and then improving the braiding quality of the diamond annular wire. And when the diamond annular wire is finally braided, the wire guiding module 4 can be split into two parts, the upper and the lower, which is convenient for taking out the diamond annular wire from the wire guiding hole 43.

[0034] Refer to Figures 2-4 , on the left and right sides of the upper wire guiding part 41, there are limiting side plates 121, and the limiting side plates 121 are fixed to the chassis 12. A detachable upper fixing block 122 is connected between the two limiting side plates 121. An abutting component 5 for pressing the upper wire guiding part 41 against the lower wire guiding part 42 is provided on the upper fixing block 122. In this way, through the abutting component 5, the upper wire guiding part 41 can be pressed against the lower wire guiding part 42. Through the limiting side plates 121, it is convenient to limit the left and right sides of the upper wire guiding part 41. On the one hand, it is convenient for the connection between the upper fixing block 122 and the limiting side plates 121. On the other hand, it can reduce the possibility of dislocation between the upper wire guiding part 41 and the lower wire guiding part 42, which is convenient for improving the assembly efficiency of the wire guiding module 4.

[0035] Refer to Figures 2-4, the pressing component 5 includes a lower movable block 51 and an elastic member 52. The lower movable block 51 is slidably connected to the upper fixed block 122 in the vertical direction. A receiving groove 1221 for receiving the lower movable block 51 is formed at the bottom end of the upper fixed block 122. The elastic member 52 is disposed between the bottom wall of the receiving groove 1221 and the lower movable block 51. The lower end of the lower movable block 51 is connected to the upper wire portion 41. When the elastic member 52 is in the natural state, the lower movable block 51 partially or completely extends out of the receiving groove 1221. In this embodiment, the elastic member 52 is a helical compression spring. When the elastic member 52 is pressed, the lower movable block 51 can gradually retract into the receiving groove 1221, so as to facilitate the separation of the upper wire portion 41 from the lower wire portion 42. When the external force is removed, the elastic member 52 resets, and the upper wire portion 41 can be pressed against the upper end of the lower wire portion 42 to realize the splicing of the upper wire portion 41 and the lower wire portion 42.

[0036] Referring to Figures 3-4 , to facilitate the separation of the upper wire portion 41 and the lower wire portion 42, a movable rod 511 is fixed to the top of the lower movable block 51. A through hole 1222 for the vertical penetration of the movable rod 511 is formed in the upper fixed block 122. The through hole 1222 communicates with the receiving groove 1221. The elastic member 52 is sleeved outside the movable rod 511. One end of the movable rod 511 away from the lower movable block 51 is connected with a pulling grip portion 512. In this embodiment, the pulling grip portion 512 is spherical and its diameter is larger than the aperture of the through hole 1222. To facilitate the installation of the movable rod 511, a threaded section 5111 is provided at one end of the movable rod 511 away from the lower movable block 51. A threaded hole 5121 adapted to the threaded section 5111 is formed at the lower end of the pulling grip portion 512, so that the pulling grip portion 512 and the movable rod 511 are detachably connected.

[0037] Referring to Figure 3 , stepped portions 1223 are integrally formed on the left and right sides of the upper fixed block 122. Reduced diameter portions 1211 adapted to the stepped portions 1223 are integrally formed on the opposite sides of the two limiting side plates 121 respectively. The reduced diameter portions 1211 and the adjacent stepped portions 1223 are connected by fasteners. Connecting holes 1212 adapted to the fasteners are formed in the reduced diameter portions 1211 and the stepped portions 1223. In this embodiment, the fasteners are bolts. In this way, the stepped portions 1223 and the reduced diameter portions 1211 are cooperatively connected, which is convenient for inserting the upper fixed block 122 from the front and rear ends of the two limiting side plates 121 and facilitating the positioning and installation of the upper fixed block 122.

[0038] Referring to Figures 3-4, a jack 5112 for inserting a pin is formed on the side wall of the movable rod 511, and a vertically arranged waist-shaped hole 1224 corresponding to the jack 5112 is formed on the side wall of the upper fixing block 122. After inserting a conventional pin into the jack 5112 through the waist-shaped hole 1224, the upper and lower limit positions of the pin are defined by the arrangement of the waist-shaped hole 1224, so that it is convenient to define the upper and lower limit positions of the movable rod 511, and the possibility of the movable rod 511 being separated from the upper fixing block 122 when removing the wire module 4 is reduced.

[0039] The above are all the 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 should be covered within the protection scope of the present application.
