Description

Technical Field

[0001] This invention relates to the field of cutting machine technology, specifically to a spindle box roller device. Background Technology

[0002] A beaded wire saw is a cutting tool with diamond beads spaced on a looped steel wire rope. It is suitable for cutting various hard materials and is currently mainly used in stone mining, construction, and slab cutting.

[0003] A wire saw cutting machine is a device used to drive a beaded wire saw to perform linear motion to achieve a cutting function. For example, Chinese invention patent application CN202310163266.7, filed on February 24, 2023, discloses a wire saw cutting device and method for granite slabs. However, existing wire saw cutting machines typically only drive one beaded wire saw, resulting in low cutting efficiency. Furthermore, because the beaded wire saw has a ring structure, installation is inconvenient. Therefore, there is an urgent need for a device that can reliably drive multiple beaded wire saws while also facilitating their installation. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a spindle box roller device that can reliably drive multiple strands of beaded wire saws and facilitate the installation of the beaded wire saws. This solves the problems of low cutting efficiency and inconvenient installation of existing wire saw cutting machines, which can only drive one beaded wire saw.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A spindle box roller assembly includes a support base, a spindle box, a transmission spindle, a drive mechanism, a transmission roller, and a rubber ring.

[0007] The transmission spindle has a first shaft section and a second shaft section. The first shaft section is rotatably mounted inside the spindle box, and the free end of the first shaft section extends to the outside of the spindle box and is connected to the drive mechanism. The transmission roller is sleeved on the outside of the second shaft section and is connected to the second shaft section. Several rubber rings are sequentially sleeved on the outer surface of the transmission roller along the axial direction, with a gap between two adjacent rubber rings. Each rubber ring has a receiving groove on its circumferential surface for accommodating a beaded wire saw. The spindle box and the drive mechanism are both mounted on a support base.

[0008] Furthermore, the interior of the transmission roller has a first tapered cavity section formed at the end away from the main spindle box, and the first tapered cavity section is equipped with a first tapered plug. The free end of the second shaft section is detachably connected to the first tapered plug. The interior of the transmission roller has a second tapered cavity section formed at the end near the main spindle box, and the second tapered cavity section is equipped with a second tapered plug. The other end of the second shaft section passes through the second tapered plug. The narrow ends of the first tapered cavity section and the second tapered cavity section are arranged facing each other.

[0009] Furthermore, the spindle box has an extended straight section inserted into the transmission roller, and an expanded diameter straight cavity section is formed inside the transmission roller at the position corresponding to the extended straight section, and the second tapered cavity section is located at the end of the expanded diameter straight cavity section close to the first tapered cavity section.

[0010] Furthermore, it also includes a locking nut, and the free end of the second shaft segment has a threaded section that passes through the first tapered plug and is locked by the locking nut.

[0011] Furthermore, the second tapered plug is connected to the second shaft segment via a key and a keyway.

[0012] Furthermore, bearing mounting sections are formed at both ends of the first shaft segment. The outer diameter of the bearing mounting section is smaller than that of the first shaft segment, and the outer diameter of the second shaft segment is smaller than that of the bearing mounting section. The two ends of the spindle box are rotatably connected to the bearing mounting section by bearings.

[0013] Furthermore, the spindle box is provided with a first oil seal structure at the end away from the drive mechanism;

[0014] The first oil seal structure includes a first oil seal end cover and a first sealing element. The first oil seal end cover is locked to the end face of the spindle box. The first sealing element is sleeved between the bearing mounting section and the first oil seal end cover. The inner surface of the first oil seal end cover has a first abutting protrusion ring for abutting the bearing.

[0015] Furthermore, a first embedding groove and a first embedding protrusion are provided between the first oil seal end cap and the second tapered plug, which are interlocked together.

[0016] Furthermore, the spindle box is provided with a second oil seal structure at one end near the drive mechanism.

[0017] The second oil seal structure includes a second oil seal end cover and a second sealing element. The second oil seal end cover is locked to the end face of the spindle box. The second sealing element is sleeved between the bearing mounting section and the second oil seal end cover. The inner surface of the second oil seal end cover has a second abutting protrusion ring for abutting the bearing.

[0018] Furthermore, the inner walls at both ends of the spindle box are formed with limiting steps for limiting the inner side of the bearing.

[0019] By adopting the above-described technical solution of the present invention, at least the following beneficial effects are achieved:

[0020] 1. By designing the transmission spindle to have a first shaft section and a second shaft section, and connecting the first shaft section to the spindle box, and fitting the transmission roller outside the second shaft section and connecting it to the second shaft section, the transmission spindle can be reliably supported by the spindle box during actual use, allowing the free end of the second shaft section to be suspended, thus facilitating the installation of the ring-shaped beaded wire saw onto the transmission roller, and also facilitating the replacement of the beaded wire saw.

[0021] 2. By sequentially fitting several rubber rings along the axial direction on the outer surface of the transmission roller, and each rubber ring having a receiving groove on its circumference for accommodating the beaded wire saw, multiple beaded wire saws can be fitted onto the transmission roller simultaneously during actual use, and the drive mechanism can drive the transmission roller to synchronously drive the multiple beaded wire saws, thereby helping to improve cutting efficiency.

[0022] 3. By designing the transmission roller to have a first tapered cavity and a second tapered cavity, a first tapered plug is installed in the first tapered cavity, and the free end of the second shaft section is detachably connected to the first tapered plug. A second tapered plug is installed in the second tapered cavity, with the narrow ends of the first and second tapered cavities facing each other. This design allows for easy replacement of the transmission roller during use. Simply detach the first tapered plug from the free end of the second shaft section and remove the first tapered plug, allowing the entire transmission roller and rubber ring to be pulled out and removed together. When a new transmission roller is fitted onto the outside of the second shaft section, simply plug the first tapered plug into the first tapered cavity, use the first and second tapered plugs to press the transmission roller together, and connect the free end of the second shaft section to the first tapered plug to complete the assembly. Therefore, the replacement of the transmission roller and rubber ring is very convenient.

[0023] 4. By equipping the two ends of the spindle box with a first oil seal structure and a second oil seal structure respectively, on the one hand, it can ensure that the lubricating oil added to the spindle box will not leak to the outside, so as to ensure that the transmission spindle can rotate more smoothly; on the other hand, it can prevent external dust and other impurities from entering the spindle box.

[0045] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0046] Please see the appendix Figures 1 to 8 As shown, the present invention provides a spindle box roller device 100, which includes a support base 1, a spindle box 2, a transmission spindle 3, a drive mechanism 4, a transmission roller 5, and a rubber ring 6; wherein: the support base 1 is used to meet the support requirements of the entire spindle box roller device 100; the spindle box 2 is used to rotatably connect with the transmission spindle 3 and meet the support requirements of the transmission spindle 3; the drive mechanism 4 is used to drive the transmission spindle 3 to rotate, and the drive mechanism 4 is specifically a drive motor; the transmission roller 5 is used to drive the rubber ring 6 to rotate together under the drive of the transmission spindle 3, thereby driving the beaded wire saw to perform transmission.

[0047] The transmission spindle 3 has a first shaft section 31 and a second shaft section 32. The first shaft section 31 is rotatably disposed inside the spindle box 2. The free end of the first shaft section 31 extends to the outside of the spindle box 2 and is connected to the drive mechanism 4 so that the drive mechanism 4 can drive the transmission spindle 3 to rotate. The transmission roller 5 is sleeved on the outside of the second shaft section 32 and is connected to the second shaft section 32 so that the second shaft section 32 can drive the transmission roller 5 to rotate together. The outer surface of the transmission roller 5 is provided with a number of rubber rings 6 along the axial direction. There is a gap between two adjacent rubber rings 6. Each rubber ring 6 has a receiving groove 61 for accommodating a beaded wire saw on its circumferential surface. The spindle box 2 and the drive mechanism 4 are both disposed on the support base 1 so that the support base 1 can support the spindle box 2 and the drive mechanism 4.

[0048] By adopting the above-described technical solution of the present invention, at least the following beneficial effects are achieved:

[0049] 1. By designing the transmission spindle 3 to have a first shaft section 31 and a second shaft section 32, and connecting the first shaft section 31 to the spindle box 2, and sleeve the transmission roller 5 on the outside of the second shaft section 32 and connect it to the second shaft section 32, the transmission spindle 3 can be reliably supported by the spindle box 2 during actual use, so that the free end of the second shaft section 32 can be suspended, thereby facilitating the installation of the ring-shaped beaded wire saw onto the transmission roller 5, and also facilitating the replacement of the beaded wire saw.

[0050] 2. By sequentially sleeved with several rubber rings 6 along the axial direction on the outer surface of the transmission roller 5, and each rubber ring 6 having a receiving groove 61 for accommodating the beaded wire saw on its circumferential surface, multiple beaded wire saws can be sleeved on the transmission roller 5 simultaneously during actual use, and the drive mechanism 4 can drive the transmission roller 5 to drive the multiple beaded wire saws to perform synchronous transmission, thereby helping to improve cutting efficiency.

[0051] In some embodiments of the present invention, please refer to the following: Figure 5 As shown, the transmission roller 5 has a first tapered cavity section 51 formed at the end away from the main spindle box 2. The first tapered cavity section 51 is equipped with a first tapered plug 71. The free end of the second shaft section 32 is detachably connected to the first tapered plug 71 for easy disassembly and assembly. The transmission roller 5 has a second tapered cavity section 52 formed at the end near the main spindle box 2. The second tapered cavity section 52 is equipped with a second tapered plug 72. The other end of the second shaft section 32 passes through the second tapered plug 72. The narrow ends of the first tapered cavity section 51 and the second tapered cavity section 52 are arranged facing each other.

[0052] This invention designs the transmission roller 5 to have a first tapered cavity section 51 and a second tapered cavity section 52 inside. A first tapered plug 71 is installed in the first tapered cavity section 51, and the free end of the second shaft section 32 is detachably connected to the first tapered plug 71. A second tapered plug 72 is installed in the second tapered cavity section 52, and the narrow ends of the first tapered cavity section 51 and the second tapered cavity section 52 are arranged facing each other. This ensures that during actual use, when it is necessary to disassemble and replace the transmission roller 5, it is only necessary to detach the first tapered plug 71 from the free end of the second shaft section 32. By removing the first tapered plug 71, the entire transmission roller 5 and rubber ring 6 can be pulled out and removed together from the free end of the second shaft section 32. After the new transmission roller 5 is fitted onto the outside of the second shaft section 32, the first tapered plug 71 is simply plugged into the first tapered cavity section 51, and the transmission roller 5 is pressed together by the cooperation of the first tapered plug 71 and the second tapered plug 72. The assembly is completed by connecting the free end of the second shaft section 32 with the first tapered plug 71. Therefore, it is very convenient to replace the transmission roller 5 and rubber ring 6.

[0053] In some embodiments of the present invention, please refer to the following: Figure 2 As shown, the spindle box 2 has an extended straight section 21 that inserts into the transmission roller 5. An expanded diameter straight cavity section 53 is formed inside the transmission roller 5 at a position corresponding to the extended straight section 21, and a second tapered cavity section 52 is located at the end of the expanded diameter straight cavity section 53 near the first tapered cavity section 51. By adopting this structural design, after assembly, the extended straight section 21 can abut against the second tapered plug 72, thereby allowing the first tapered plug 71 and the second tapered plug 72 to better tighten the transmission roller 5.

[0054] In some embodiments of the present invention, the spindle box roller device 100 further includes a locking nut 81, and the free end of the second shaft section 32 forms a threaded section 321, which passes through the first tapered plug 71 and is locked by the locking nut 81. The present invention uses the locking nut 81 in conjunction with the threaded section 321 to lock the free end of the second shaft section 32 onto the first tapered plug 71. This facilitates actual assembly and disassembly operations, and by rotating the locking nut 81, a force is applied to the first tapered plug 71, ensuring that the first tapered plug 71 and the second tapered plug 72 reliably press against the transmission roller 5, thereby ensuring that the transmission roller 5 does not move axially during operation and improving operational stability.

[0055] In one specific embodiment of the present invention, the second tapered plug 72 and the second shaft section 32 are connected by a key and a keyway (not shown) to facilitate actual assembly operations; during operation, the second shaft section 32 can drive the second tapered plug 72 to rotate, thereby driving the transmission roller 5 to rotate.

[0056] In some embodiments of the present invention, please refer to the following: Figure 7 As shown, bearing mounting sections 311 are formed at both ends of the first shaft segment 31. The outer diameter of the bearing mounting section 311 is smaller than that of the first shaft segment 31, and the outer diameter of the second shaft segment 32 is smaller than that of the bearing mounting section 311, so as to facilitate the assembly of the bearing 82 onto the bearing mounting section 311. At the same time, the first shaft segment 31 can be used to limit one end of the bearing 82. The two ends of the spindle box 2 are rotatably connected to the bearing mounting section 311 through the bearing 82. In a specific implementation of the present invention, at least two bearings 82 can be provided between the two ends of the spindle box 2 and the bearing mounting section 311, so that the spindle box 2 can better meet the support requirements of the transmission spindle 3.

[0057] In some embodiments of the present invention, please refer to the following: Figure 3 As shown, the spindle box 2 is provided with a first oil seal structure 91 at the end away from the drive mechanism 4;

[0058] The first oil seal structure 91 includes a first oil seal end cap 911 and a first sealing element 912. The first oil seal end cap 911 is locked to the end face of the spindle box 2. Specifically, multiple screws can be used to lock the first oil seal end cap 911 to the end face of the spindle box 2. The first sealing element 912 is sleeved between the bearing mounting section 311 and the first oil seal end cap 911 to achieve a sealing effect. The first sealing element 912 can be a rubber sealing element. The inner surface of the first oil seal end cap 911 has a first abutting protrusion ring 9111 for abutting the bearing 82. After assembly, the first abutting protrusion ring 9111 and the first shaft section 31 can cooperate to limit the two ends of the bearing 82, thereby ensuring that the bearing 82 will not move axially.

[0059] In some embodiments of the present invention, a first embedding groove 101 and a first embedding protrusion 102 are provided between the first oil seal end cap 911 and the second tapered plug 72, which are interlocked together. By adopting the above structural design, it is ensured that the second tapered plug 72 can rotate relative to the first oil seal structure 91, and that the first oil seal structure 91 can provide a supporting effect on the second tapered plug 72.

[0060] In some embodiments of the present invention, please refer to the following: Figure 4 As shown, the spindle box 2 is provided with a second oil seal structure 92 at one end near the drive mechanism 4;

[0061] The second oil seal structure 92 includes a second oil seal end cap 921 and a second sealing element 922. The second oil seal end cap 921 is locked to the end face of the spindle box 2. Specifically, multiple screws can be used to lock the second oil seal end cap 921 to the end face of the spindle box 2. The second sealing element 922 is sleeved between the bearing mounting section 311 and the second oil seal end cap 921 to achieve a sealing effect. The second sealing element 922 can be a rubber sealing element. The inner surface of the second oil seal end cap 921 has a second abutting protrusion ring 9211 for abutting the bearing 82. After assembly, the second abutting protrusion ring 9211 and the first shaft section 31 can cooperate to limit the two ends of the bearing 82, thereby ensuring that the bearing 82 will not move axially.

[0062] The present invention provides a first oil seal structure 91 and a second oil seal structure 92 at both ends of the spindle box 2. On the one hand, it can ensure that the lubricating oil added to the spindle box 2 will not leak to the outside, so as to ensure that the transmission spindle 3 can rotate more smoothly. On the other hand, it can prevent external dust and other impurities from entering the interior of the spindle box 2.

[0063] In some embodiments of the present invention, the inner walls at both ends of the spindle box 2 are formed with limiting steps 22 for limiting the inner side of the bearing 82, so as to limit the bearing 82 by means of the limiting steps 22.

[0064] In some embodiments of the present invention, the outer surface of the transmission roller 5 is provided with a second embedding groove 54, and the inner surface of the rubber ring 6 is provided with a second embedding protrusion 62. The second embedding protrusion 62 is embedded in the second embedding groove 54 to ensure that the rubber ring 6 sleeved on the transmission roller 5 will not move axially during operation.

[0065] Please refer to the following carefully. Figure 8 As shown, in practical use, the spindle box roller device 100 of the present invention requires the cooperation of multiple spindle box roller devices 100. For example, four spindle box roller devices 100 can be used together. In specific installation, two of the spindle box roller devices 100 need to be installed on a support column 200 through the support base 1, and the other two spindle box roller devices 100 need to be installed on another support column 200 through the support base 1. The two spindle box roller devices 100 on the same support column 200 are arranged vertically. The beaded wire saw is sleeved on the transmission roller 5 of each spindle box roller device 100. The beaded wire saw can then be driven by the cooperation of each spindle box roller device 100 to achieve the cutting function.

[0066] Although embodiments of the 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 invention, the scope of which is defined by the appended claims and their equivalents.
