Description

Technical Field

[0001] This utility model relates to the field of roller assembly and disassembly technology, and more specifically, to a roller auxiliary assembly and disassembly device and a roller driving device. Background Technology

[0002] In the natural stone processing workflow, a crucial step is the cutting of raw blocks. Traditional stone cutting typically uses saw blades, wire saws, band saws, and other tools with alloy cutting tips. Emerging diamond wire saws, due to the inherent characteristics of diamond wires—contacting the flexible surface of the stone without instantaneous impact loads—result in minimal vibration and low noise. Their small wire diameter (generally no more than 1mm) creates a kerf of less than 1mm, significantly increasing yield. Furthermore, the absence of impact prevents stone breakage during cutting, leading to their increasing application in stone processing.

[0003] Emerging diamond wire saws mainly consist of roller drive equipment. Existing roller drive equipment includes a first end shaft, a second end shaft, a roller, a tie rod, and a locking nut. The two ends of the roller are connected to the first end shaft and the second end shaft, respectively. The tie rod passes through the second end shaft and the roller. One end of the tie rod is threaded to the first end shaft, and the other end of the tie rod extends out of the second end shaft away from the roller. The locking nut is threaded to the tie rod and is located at the end of the second end shaft away from the roller. The locking nut is used to apply force to the second end shaft as it approaches the roller. Most of the roller ends have concave conical surfaces, while the driving end shaft and the driven end shaft have convex conical surfaces. Power is mainly transmitted by the frictional force between the convex conical surface of the driving end shaft or the convex conical surface of the driven end shaft and the concave conical surface of the roller. However, slippage is prone to occur between the roller and the driving end shaft or the driven end shaft in some existing roller drive equipment. Utility Model Content

[0004] The purpose of this utility model is to provide a roller auxiliary disassembly and assembly device, which can reduce slippage between the roller and the passive end shaft or the active end shaft.

[0005] The embodiments of this utility model can be implemented as follows:

[0006] In a first aspect, this utility model provides a roller auxiliary assembly / disassembly device, applied to a roller driving device. The roller driving device includes a first end shaft, a second end shaft, a roller, a pull rod, and a locking nut. Both ends of the roller are connected to the first end shaft and the second end shaft, respectively. The pull rod passes through the second end shaft and the roller. One end of the pull rod is threadedly connected to the first end shaft, and the other end of the pull rod extends out of the second end shaft away from the roller. The locking nut is threadedly connected to the pull rod and located at the end of the second end shaft away from the roller.

[0010] In an optional embodiment, the mating component is a mating sleeve, which is used to be fitted onto the pull rod and can abut against the end of the second end shaft that is away from the roller. When the mating sleeve is fitted onto the pull rod, the end of the mating sleeve that is away from the second end shaft abuts against the housing of the drive component.

[0011] In an optional embodiment, the mating sleeve has an auxiliary window. When the mating sleeve is fitted onto the pull rod, the locking nut is located inside the mating sleeve, and the auxiliary window is used to expose the locking nut.

[0012] In an optional embodiment, the connector has a threaded hole for threaded connection with the pull rod, and the connector is fixedly connected to the drive end of the drive component.

[0013] In an optional embodiment, the roller auxiliary disassembly and assembly device further includes threaded fasteners, and the drive end of the drive component can be fixedly connected to the connector through the threaded fasteners.

[0014] In an optional embodiment, the outer peripheral wall of the connector is further provided with an external thread, the threaded fastener is a clamping nut, the driving end of the driving member is sleeved on the connector, the clamping nut is sleeved on the connector and the clamping nut abuts against the end face of the driving end of the driving member away from the locking nut, so as to fix the driving end of the driving member to the connector, and the driving member is used to connect with the second end shaft head.

[0018] This utility model provides a roller auxiliary assembly / disassembly device and a roller driving device. The roller driving device is compatible with the roller auxiliary assembly / disassembly device. The roller auxiliary assembly / disassembly device includes a connector and a driving component. The connector is used to connect with a pull rod. The driving component is used to drive the connector to stretch the pull rod along its own axial direction. After the pull rod is stretched, the locking nut on the pull rod will separate from the second shaft head by a preset distance in the direction away from the roller. Then, the operator can rotate the locking nut and make the locking nut press against the end face of the second shaft head again, so that the second shaft head is pressed against the end face of the roller. The operator can unload the driving force of the driving component.

[0030] It should be noted that, where there is no conflict, the features in the embodiments of this utility model can be combined with each other.

[0031] The following describes in detail, with reference to the accompanying drawings, the specific structure of a roller auxiliary disassembly and assembly device provided by this utility model and its corresponding technical effects.

[0032] Please refer to Figures 1-3 This embodiment provides a roller auxiliary disassembly and assembly device 100, which is mainly used for the installation of roller 230 in roller drive equipment 200.

[0033] It should be noted that the roller drive device 200 includes a first end shaft 210, a second end shaft 220, a roller 230, a pull rod 240, and a locking nut 250. The two ends of the roller 230 are respectively connected to the first end shaft 210 and the second end shaft 220. The pull rod 240 passes through the second end shaft 220 and the roller 230. One end of the pull rod 240 is threadedly connected to the first end shaft 210, and the other end of the pull rod 240 extends out of the second end shaft 220 away from the roller 230. The locking nut 250 is threadedly connected to the pull rod 240 and is located at the end of the second end shaft 220 away from the roller 230. The locking nut 250 is used to apply force to the second end shaft 220 as it approaches the roller 230.

[0034] The roller auxiliary disassembly and assembly device 100 provided in this embodiment includes a connector 110 and a drive component 120. The connector 110 is used to connect with the pull rod 240, and the drive component 120 is used to drive the connector 110 to stretch the pull rod 240 along its own axial direction.

[0035] It should be noted that the connector 110 is used to connect to one end of the pull rod 240 extending out of the second end shaft 220. The drive member 120 can drive the connector 110 to move away from the roller 230 in the axial direction of the pull rod 240 so as to stretch the pull rod 240 along its own axial direction. The pull rod 240 is generally made of metal material, such as steel.

[0036] Understandably, the power transmission between the roller 230 and the second end shaft 220 mainly relies on the friction between the end faces of the second end shaft 220 and the roller 230. Currently, most operators tighten the second end shaft 220 and the roller 230 using the locking nut 250 by tightening the locking nut 250 with a wrench to provide a preload between the second end shaft 220 and the roller 230. However, when tightening the locking nut 250 with a wrench, the operator can only rely on experience to judge, which often leads to insufficient preload, causing slippage between the second end shaft 220 and the roller 230.

[0037] In this embodiment, after the connector 110 is connected to one end of the pull rod 240 extending from the second end shaft 220, the drive member 120 drives the connector 110 to stretch the pull rod 240 along its own axis. After the pull rod 240 is stretched, the locking nut 250 on the pull rod 240 will separate from the second end shaft 220 by a predetermined distance in a direction away from the roller 230. Then, the operator can rotate the locking nut 250 and make the locking nut 250 close to the second end shaft 220 again. The end face of the roller 230 is pressed together with the end face of the second end shaft 220, so that the operator can release the driving force of the drive component 120 and remove the drive component 120 and the connecting component 110 from the pull rod 240. At this time, the pull rod 240 will gradually return from the stretched state to the original state. At this time, the elastic energy stored inside the pull rod 240 is converted into a pressing force on the concave and convex conical surfaces between the roller 230 and the second end shaft 220 or the first end shaft 210, which is the so-called preload force. This preload force ensures that the roller 230 can be firmly installed between the second end shaft 220 and the first end shaft 210.

[0038] Understandably, the aforementioned preset distance can be intuitively represented by the driving force of the drive component 120 to indicate the preload. Therefore, the operator can intuitively set the preload to eliminate slippage between the roller 230 and the first end shaft 210 and the second end shaft 220.

[0039] In detail, the roller auxiliary disassembly and assembly device 100 also includes a mating component for connecting with the second end shaft head 220, and the drive component 120 is connected to the mating component. It is understood that the drive component 120 can be connected to the second end shaft head 220 through the mating component; therefore, when the drive component 120 is started, the second end shaft head 220 can provide support for the movement of the drive component 120.

[0040] In detail, in this embodiment, the mating component is a mating sleeve 140. The mating sleeve 140 is used to be sleeved on the pull rod 240 and can abut against the end of the second end shaft 220 away from the roller 230. When the mating sleeve 140 is sleeved on the pull rod 240, the end of the mating sleeve 140 away from the second end shaft 220 abuts against the outer shell of the drive component 120, and the locking nut 250 is located inside the mating sleeve 140.

[0041] Of course, in some other embodiments, the mating component is not limited to the mating sleeve 140 sleeved on the pull rod 240, as long as it can be detachably connected to the second end shaft head 220 or can provide fixed support for the drive component 120.

[0042] In detail, in this embodiment, the driving component 120 includes a hollow hydraulic cylinder 121. That is, the cylinder of the hollow hydraulic cylinder 121 abuts against the end of the mating sleeve 140 away from the second end shaft head 220. The piston of the hollow hydraulic cylinder 121 can drive the connecting component 110 to stretch the pull rod 240. It can be understood that when the piston moves away from the roller 230, the hollow hydraulic cylinder 121 will also give the mating sleeve 140 a force toward the roller 230 to further press the end shaft head 220 and the end face of the roller 230 together.

[0043] Of course, in some alternative embodiments, the drive unit 120 is not limited to the hydraulic cylinder 121, but can also be other types of drive structures, such as cylinders, linear telescopic motors, etc.

[0044] In this embodiment, when the fitting sleeve 140 is fitted onto the pull rod 240, the locking nut 250 is located inside the fitting sleeve 140. The fitting sleeve 140 has an auxiliary window 141, which is used to expose the locking nut 250. It can be understood that the auxiliary window 141 makes it easier for the operator to tighten the locking nut 250.

[0045] In detail, the connector 110 has a threaded hole for threaded connection with the pull rod 240, and the connector 110 can also be fixedly connected to the drive end of the drive component 120. It can be understood that the connector 110 is threadedly connected to the pull rod 240 through the threaded hole; that is, the outer peripheral wall of the pull rod 240 is provided with external threads, and the connection between the connector 110 and the pull rod 240 is ensured by the threaded connection.

[0046] The roller auxiliary disassembly and assembly device 100 also includes threaded fasteners, and the drive end of the drive component 120 can be fixedly connected to the connector 110 through the threaded fasteners. It can be understood that fixing the drive end of the drive component 120 to the connector 110 through the threaded fasteners can ensure the connection strength between the drive end of the drive component 120 and the connector 110, and also facilitate the disassembly and assembly of the drive end of the drive component 120 and the connector 110.

[0047] In detail, in this embodiment, the outer peripheral wall of the connector 110 is also provided with an external thread, the threaded fastener is a clamping nut 130, the driving end of the driving member 120 is sleeved on the connector 110, the clamping nut 130 is sleeved on the connector 110 and the clamping nut 130 abuts against the end face of the driving end of the driving member 120 away from the locking nut 250, so as to fix the driving end of the driving member 120 to the connector 110. The driving member 120 is used to connect with the second end shaft head 220. In detail, the outer shell of the driving member 120 can indirectly abut against the end face of the second end shaft head 220 away from the roller 230 through the mating sleeve 140.

[0048] In other words, in this embodiment, the piston of the hollow hydraulic cylinder 121 is sleeved on the outer peripheral wall of the connector 110. In order to ensure the stability of the connection between the piston and the connector 110, the outer peripheral wall of the connector 110 can also be provided with a limiting boss. After the clamping nut 130 is sleeved on the outer peripheral wall of the connector 110, the piston is located between the clamping nut 130 and the limiting boss.

[0049] It should be noted that in this embodiment, the drive unit 120 includes a hollow hydraulic cylinder 121 and a hand pump 122 connected to each other. The hand pump 122 allows the operator to manually adjust the pressure. It should also be noted that the hand pump 122 is generally equipped with a pressure gauge, which also allows the operator to manually adjust the pressure.

[0050] Working principle:

[0051] In this embodiment, the roller auxiliary disassembly and assembly device 100 is applied to the roller drive equipment 200 and is used to install the roller 230. The mating sleeve 140 can be pre-fitted onto the pull rod 240 and the end face of the mating sleeve 140 can be made to abut against the end face of the second end shaft head 220 away from the roller 230. Then, the threaded hole of the connector 110 is threadedly connected to the pull rod 240, and the piston of the hollow hydraulic cylinder 121 is fitted onto the connector 110 and the clamping nut 130 is used to fix the piston onto the connector 110. The operator can pump oil into the hydraulic cylinder 121 using the hand pump 122, causing the piston of the hydraulic cylinder 121 to move away from the roller 230. This causes the clamping nut 130 to drive the connecting piece 110 to move away from the roller 230, thereby stretching the pull rod 240. At this time, the locking nut 250 on the pull rod 240 is separated from the end face of the second end shaft 220 by a predetermined distance. The operator can rotate the locking nut 250 through the auxiliary window 141. Until the locking nut 250 is once again pressed against the end face of the second end shaft 220 and the end face of the roller 230 is pressed together, the operator can release the pressure of the hydraulic cylinder 121 and remove the entire roller auxiliary disassembly and assembly device 100 from the pull rod 240. This completes the assembly of the roller 230 with the first end shaft 210 and the second end shaft 220, so that the roller 230 is stably installed between the first end shaft 210 and the second end shaft 220.

[0052] In this embodiment, the roller auxiliary disassembly and assembly device 100 is applied to the roller drive equipment 200 and is used to disassemble the roller 230. Similarly, the mating sleeve 140 can be pre-fitted onto the pull rod 240 and the end face of the mating sleeve 140 can be made to abut against the end face of the second end shaft head 220 away from the roller 230. Then, the threaded hole of the connector 110 is threadedly connected to the pull rod 240, and the piston of the hollow hydraulic cylinder 121 is fitted onto the connector 110 and the clamping nut 130 is used to fix the piston onto the connector 110. The operator can pump oil into the hydraulic cylinder 121 using the hand pump 122, causing the piston of the hydraulic cylinder 121 to move away from the roller 230. This causes the clamping nut 130 to drive the connecting piece 110 to move away from the roller 230, thereby stretching the pull rod 240. At this time, the locking nut 250 on the pull rod 240 is separated from the end face of the second end shaft 220 by a predetermined distance. The operator can rotate the locking nut 250 through the auxiliary window 141, causing the locking nut 250 to move away from the roller 230 by a distance greater than the aforementioned predetermined distance. The spacing, that is, the removal of the preload on the locking nut 250, allows the operator to release the pressure of the hydraulic cylinder 121 and remove the entire roller auxiliary disassembly and assembly device 100 from the pull rod 240. The locking nut 250 can then be easily removed from the pull rod 240. The operator can then rotate the pull rod 240 and unscrew it from the first end shaft 210. After pulling out the entire pull rod 240, the operator can use the roller 230 disassembly and assembly device to remove the roller 230 from between the first end shaft 210 and the second end shaft 220, thus completing the disassembly of the roller 230.

[0053] Please continue to refer to this. Figure 1 This utility model embodiment also provides a roller drive device 200, which can be adapted to the roller auxiliary disassembly and assembly device 100 described above.

[0054] As described above, the roller drive device 200 also includes a first end shaft 210, a second end shaft 220, a pull rod 240, and a locking nut 250. The two ends of the roller 230 are respectively connected to the first end shaft 210 and the second end shaft 220. The pull rod 240 passes through the second end shaft 220 and the roller 230. One end of the pull rod 240 is threadedly connected to the first end shaft 210, and the other end of the pull rod 240 passes through the end of the second end shaft 220 away from the roller 230. The locking nut 250 is threadedly connected to the pull rod 240 and is located at the end of the second end shaft 220 away from the roller 230. The locking nut 250 is used to apply force to the second end shaft 220 as it approaches the roller 230.

[0055] The first end shaft 210 can be the driving end shaft, and the second end shaft 220 can be the driven end shaft. In order to ensure the connection strength between the roller 230 and the first end shaft 210 and the second end shaft 220 and to ensure the stability of the force transmission, both the first end shaft 210 and the second end shaft 220 have a convex conical surface, and both ends of the roller 230 are provided with concave conical surfaces that cooperate with the convex conical surfaces.

[0056] Please refer to Figure 4 In detail, in this embodiment, the roller 230 is provided with a guide through hole 231. The axis of the guide through hole 231 is coaxial with the axis of the roller 230 body. The guide through hole 231 is used for the pull rod 240 to pass through. It can be understood that by setting the guide through hole 231, it is convenient for the operator to pass the pull rod 240 through and align it with the threaded hole of the first end shaft head 210 in time, thereby improving the installation efficiency of the operator on the roller 230.

[0057] Alternatively, in some other embodiments, the outer peripheral wall of the roller 230 is coated with a wear-resistant layer. The wear-resistant layer 232 can prevent the outer peripheral wall of the roller 230 from being easily scratched, thereby improving the service life of the roller 230.

[0058] In summary, this utility model embodiment provides a roller auxiliary assembly / disassembly device 100 and a roller driving device 200. The roller driving device 200 is compatible with the roller auxiliary assembly / disassembly device 100. The roller auxiliary assembly / disassembly device 100 includes a connector 110 and a driving component 120. The connector 110 is used to connect with the pull rod 240. The driving component 120 is used to drive the connector 110 to stretch the pull rod 240 along its own axial direction. Then, the driving component 120 drives the connector 110 to stretch the pull rod 240 along its own axial direction. After the pull rod 240 is stretched, the locking nut 2 on the pull rod 240... 50 will separate from the second shaft head by a preset distance in the direction away from the roller 230, so that the operator can rotate the locking nut 250 and make the locking nut 250 press against the end face of the second shaft head 220 again, so that the end face of the second shaft head 220 and the end face of the roller 230 are pressed together. The operator can unload the driving force of the drive component 120, and the elastic energy stored in the pull rod 240 is converted into a pressing force on the concave and convex conical surfaces between the roller 230 and the second shaft head 220 or the first shaft head 210, so as to eliminate the slippage between the roller 230 and the first shaft head 210 and the second shaft head 220.

[0059] The above description is only a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model.
