Description

Technical Field

[0001] This utility model relates to the field of tobacco machinery technology, and in particular to a bearing housing assembly replacement tooling. Background Technology

[0002] In the tobacco industry, vibrating conveyors are essential conveying equipment, primarily used for transporting materials. A common type of vibrating conveyor is the eccentric linkage vibrating conveyor, which mainly consists of a motor, pulleys, connecting rods, and an eccentric device. The eccentric device primarily includes an eccentric shaft, bearings, and bearing housings. The eccentric device is usually installed at the bottom of the vibrating trough. Due to its complex structure and the high dynamic load and stress it bears, the eccentric device is prone to damage after a period of operation under the combined effects of enormous driving force and synchronous vibration, requiring replacement of the eccentric shaft or bearings.

[0003] Because of the large weight of the eccentric device and its low or high installation position, it usually requires the cooperation of multiple maintenance personnel when disassembling and assembling the eccentric device of the vibrating conveyor. This not only increases the labor intensity of the maintenance personnel and reduces work efficiency, but also poses certain safety hazards. Utility Model Content

[0004] The purpose of this invention is to solve the technical problems of high labor intensity, low work efficiency, and certain safety hazards in the disassembly and assembly of eccentric devices by maintenance personnel in the prior art. This invention provides a bearing housing assembly replacement fixture that can adjust the height of the bearing housing while supporting the eccentric device. This device can not only reduce the labor intensity of maintenance personnel and improve work efficiency, but also eliminate safety hazards during replacement.

[0005] To solve the above-mentioned technical problems, this utility model discloses a bearing housing assembly replacement fixture. The bearing housing assembly includes a shaft and two bearing housings disposed at both ends of the shaft along its extension direction. The replacement fixture includes:

[0006] The lifting unit has a support plate on its top, which can move up and down vertically.

[0007] The support frame consists of two supports, which are spaced apart above the support plate along the first direction. The positions of the two supports correspond one-to-one with the positions of the two bearing seats. The two supports are used to support the two bearing seats respectively, and the shape of the upper surface of the support frame is adapted to the bottom shape of the bearing seat.

[0008] An adjustment mechanism is located between the support frame and the tray. The adjustment mechanism is used to adjust the distance between the two support frames along the first direction.

[0009] By adopting the above technical solution, the replacement tooling provided by this utility model can quickly disassemble and assemble the bearing housing assembly, which can not only save manpower, reduce the labor intensity of maintenance personnel, and improve the work efficiency of maintenance personnel, but also eliminate the safety hazards caused by the excessive weight of the bearing housing assembly during the maintenance process.

[0013] The two limiting parts are located on the opposite side of the bearing housing assembly of the two supporting parts, and the two limiting parts are used to prevent the bearing housing assembly from displacing in the first direction.

[0014] By adopting the above technical solution, the arc-shaped support not only better adapts to the shape of the bearing housing and increases the contact area between the support and the bearing housing, making the support frame more stable in supporting the bearing housing assembly, but also effectively encloses the bearing housing. This facilitates timely adjustment of the bearing and bearing housing positions during the assembly and disassembly of the bearing housing assembly, allowing for more convenient and precise alignment of the bolt holes. Simultaneously, the limiting part prevents the bearing housing assembly from detaching from the support frame during lifting or lowering.

[0015] Optionally, the support frame may also include a support portion located below the support portion for supporting the support portion.

Each seat has a strip hole extending along the first direction, and the supports are connected to the strip hole by bolts and nuts.

[0017] By adopting the above technical solution, the position of the support in the horizontal direction can be adjusted by adjusting the position of the bolt in the strip hole, thereby adjusting the distance between the two support frames to better support different bearing seat assemblies.

[0018] Optionally, each support portion has at least two support portions below it, and the number of slotted holes on the base body is equal to the number of support portions corresponding to that base body. Each support portion and its corresponding slotted hole are connected by bolts and nuts.

The upper end of the first rod is hinged to the upper slider, and the lower end of the first rod is hinged to the base frame. The upper end of the second rod is hinged to the support plate, and the lower end of the second rod is hinged to the lower slider.

[0025] Optionally, the number of linkage assemblies is two, and the two linkage assemblies are spaced apart along a second direction, which is perpendicular to the first direction.

[0026] By adopting the above technical solution, the lifting unit provided by this utility model has a simple structure, is easy to operate, and has high stability.

[0027] Optionally, the linear drive mechanism includes:

[0028] A lead screw extends along a first direction and is rotatably connected to a base frame; a second threaded hole is provided on the lower slider along the first direction, and the lead screw passes through the second threaded hole and is threadedly connected to the second threaded hole.

Those skilled in the art can understand the specific meaning of the above terms in this embodiment based on the specific circumstances.

[0043] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0044] This embodiment provides a bearing housing assembly replacement fixture, applicable to the disassembly and assembly of bearing housing assemblies including a shaft and bearing housings, wherein the bearing housings are located at both ends of the shaft along its extension direction. For ease of description, this embodiment of the present invention uses the bearing housing assembly as an eccentric device of a vibrating conveyor as an example for detailed explanation.

[0045] In the prior art, see Figure 1 The eccentric device 1 of the vibrating conveyor includes an eccentric shaft 11, bearings 12, and bearing housings 13. Two bearings 12 are spaced apart at both ends of the eccentric shaft 11 along its extension direction, and each bearing 12 is housed within a bearing housing 13. Due to the significant weight of the eccentric device 1 and its installation position (either low or high), maintenance personnel are typically limited by weight and space constraints when replacing it. This not only requires multiple maintenance personnel to work together, increasing their workload, but also poses certain safety hazards.

[0046] To solve the above technical problems, see Figure 1 and Figure 2 This utility model provides a bearing housing assembly replacement fixture, which includes a lifting unit 2, a support frame 3, and an adjusting mechanism 4. The top of the lifting unit 2 is provided with a support plate 21, which can move up and down in the vertical direction. There are two support frames 3, which are aligned along a first direction (e.g., ...). Figure 2 The two support frames 3 (as shown in the X direction) are spaced apart above the support plate 21, with their positions corresponding one-to-one with the positions of the two bearing seats 13. The two support frames 3 support the two bearing seats 13 respectively, and the shape of the upper surface of the support frame 3 matches the bottom shape of the bearing seat 13. An adjustment mechanism 4 is located between the support frame 3 and the support plate 21, and is used to adjust the spacing between the two support frames 3 along the X direction.

[0047] When it is necessary to disassemble and assemble the eccentric device 1, the maintenance personnel first place the replacement tool under the eccentric device 1, and then raise the pallet 21 to a position close to the eccentric device 1 by controlling the lifting unit 2. The maintenance personnel adjust the position of the two support frames 3 through the adjusting mechanism 4 so that the two support frames 3 can support the two bearing seats 13 respectively. Then, the maintenance personnel control the lifting unit 2 again to raise the pallet 21 until the support frame 3 contacts the bearing seat 13. At this time, the maintenance personnel remove the eccentric device 1 from the vibrating conveyor. After removal, the maintenance personnel control the lifting unit 2 to lower the pallet 21, and then perform maintenance on the eccentric device 1. After maintenance, the maintenance personnel place the eccentric device 1 back on the support frame 3, and the lifting unit 2 raises the pallet 21 to send the eccentric device 1 to the installation position. The maintenance personnel then reinstall the eccentric device 1 onto the vibrating conveyor, and the maintenance is complete.

[0048] By adopting the above technical solution, the replacement tooling provided by this utility model can quickly disassemble and assemble the eccentric device 1 on the vibrating conveyor. This not only saves manpower, reduces the labor intensity of maintenance personnel, and improves the work efficiency of maintenance personnel, but also eliminates the safety hazards caused by the excessive weight of the eccentric device 1 during the maintenance process.

[0049] Further, see Figure 1 The bottom of the bearing housing 13 is arc-shaped, and the support frame 3 includes a supporting portion 31 and a limiting portion 32. The upper surface of the supporting portion 31 is configured to be arc-shaped to match the bottom of the bearing housing 13. The limiting portion 32 is disposed on the upper surface of the supporting portion 31, and the two limiting portions 32 are respectively located on the side of the two supporting portions 31 opposite to the bearing housing 13. The two limiting portions 32 are used to prevent the bearing housing 13 from displacing in the X direction. In one embodiment of the present invention, exemplarily, the width of the supporting portion 31 in the X direction is greater than the width of the bearing housing 13 in the X direction, and the limiting portion 32 is U-shaped and perpendicular to the supporting portion 31. The arc-shaped support portion 31 not only better adapts to the shape of the bearing housing 13, increasing the contact area between the support portion 31 and the bearing housing 13, making the support frame 3 more stable in supporting the eccentric device 1, but also effectively encloses the bearing housing 13, facilitating the adjustment of the position of the bearing 12 and the bearing housing 13 when assembling and disassembling the eccentric device 1, and allowing for more convenient and precise alignment of the bolt holes. Simultaneously, the limiting portion 32 prevents the eccentric device 1 from detaching from the support frame 3 during lifting or lowering.

[0050] Specifically, see Figure 2The support frame 3 also includes a support portion 33, which is disposed below the supporting portion 31 and is used to support the supporting portion 31. In one embodiment of this utility model, exemplarily, the support portion 33 is L-shaped, and the bottom of the support portion 33 is provided with a first threaded hole 331 extending through the support portion 33 along its thickness direction. There are four support portions 33, and each supporting portion 31 has two threads 331 extending along a second direction (e.g., ...) below it. Figure 2 The support portions 33 (shown in the Y direction) are spaced apart, and the second direction is perpendicular to the first direction.

[0051] Specifically, see Figure 2 The adjusting mechanism 4 includes two seats 41 spaced apart along the X direction. The two seats 41 are located below the two support portions 33, and are connected to the support plate 21. This invention does not specifically limit the connection method between the seats 41 and the support plate 21; they can be connected by welding or other methods. In one embodiment of this invention, exemplarily, the seats 41 and the support plate 21 are connected by bolts and nuts.

[0052] See Figure 2 Each base 41 has a strip-shaped hole 411 extending in the X direction. The support part 33 is connected to the strip-shaped hole 411 by a locking bolt 42 and a locking nut 43. The locking bolt 42 passes through the first threaded hole 331 and the strip-shaped hole 411 in sequence and is threadedly connected to the first threaded hole 331 and the locking nut 43. The locking nut 43 is located on the side of the locking bolt 42 away from the support part 33. By adjusting the position of the locking bolt 42 in the strip-shaped hole 411, the position of the support part 33 in the horizontal direction can be adjusted, thereby adjusting the distance between the two support frames 3 to better support the different eccentric devices 1.

[0053] In one embodiment of this utility model, exemplarily, see [link to embodiment]. Figure 2 The base 41 is M-shaped, and the number of slotted holes 411, locking bolts 42, and locking nuts 43 is equal to the number of support parts 33. Each base 41 has two slotted holes 411 corresponding to the positions of the support parts 33, and there is a certain distance between the plane of the slotted holes 411 and the plane of the support plate 21. The M-shaped base 41 can avoid the problem of interference between the locking bolts 42 and locking nuts 43 and the lifting unit 2 when the slotted holes 411 are directly opened on the support plate 21, and can also provide operating space for the operator and accommodate locking bolts 42 and locking nuts 43 of more sizes.

[0054] This application does not specify the dimensions of the support frame 3; operators can select one based on the dimensions of the bearing housing 13. For different bearing housings 13, operators can first remove the support frame 3 from the base 41 by unscrewing the locking bolts 42 and locking nuts 43, and then install the appropriate support frame 3 onto the base 41 to complete the subsequent replacement work, demonstrating high versatility.

[0055] Further, see Figure 2 and Figure 3 The lifting unit 2 includes a base frame 22, a lower slider 23, an upper slider 24, a linear drive mechanism, and a linkage assembly 26. The lower slider 23 is slidably connected to the base frame 22, and the upper slider 24 is slidably connected to the support plate 21. The linear drive mechanism is connected to the lower slider 23 and is used to drive the lower slider 23 to reciprocate along the X direction. The linkage assembly 26 includes a first rod 261 and a second rod 262, which are hinged at their middle parts. The upper end of the first rod 261 is hinged to the upper slider 24, and the lower end of the first rod 261 is hinged to the base frame 22. The upper end of the second rod 262 is hinged to the support plate 21, and the lower end of the second rod 262 is hinged to the lower slider 23. There are two linkage assemblies 26, which are spaced apart along the Y direction.

[0056] In practical operation, if it is necessary to raise the pallet 21, the linear drive mechanism simply drives the lower slider 23 to move along the X direction towards the lower end of the first rod 261. At this time, the upper end of the first rod 261 and the upper end of the second rod 262 gradually approach each other, thus raising the position of the pallet 21. If it is necessary to lower the pallet 21, the linear drive mechanism simply drives the lower slider 23 to move along the X direction away from the lower end of the first rod 261. At this time, the upper end of the first rod 261 and the upper end of the second rod 262 gradually move away from each other, thus lowering the position of the pallet 21. This lifting unit 2 has a simple structure, is easy to operate, and has high stability.

[0057] Specifically, see Figure 3 The linear drive mechanism includes a lead screw 251 and a drive element (not shown in the figure). The lead screw 251 extends along the X direction and is rotatably connected to the base frame 22. See also... Figure 2The sliding block 23 includes two sliding rollers 231 and a first connecting block 232. The two sliding rollers 231 are respectively disposed at the lower ends of the two second rods 262 opposite to the first connecting block 232. Both the two sliding rollers 231 and the first connecting block 232 are hinged to the lower ends of the second rods 262. The first connecting block 232 has a second threaded hole 2321 that passes through the first connecting block 2322 in the X direction. The lead screw 251 passes through the second threaded hole 2321 and is threadedly connected to the second threaded hole 2321. The output end of the driving component is connected to the lead screw 251, and the driving component is used to drive the lead screw 251 to rotate around its own axis. This utility model does not specifically limit the type of driving component. It can be a motor, an electric wrench, or other devices, as long as it can drive the lead screw 251 to rotate around its own axis.

[0058] Specifically, see Figure 2 and Figure 3 The base frame 22 has two first sliding grooves 221 extending along the X direction, and the two first sliding grooves 221 are arranged opposite each other on both sides of the base frame 22 along the Y direction. Two lower sliding wheels 231 are slidably disposed in the two first sliding grooves 221 respectively. The support plate 21 has two second sliding grooves 211 extending along the X direction, and the two second sliding grooves 211 are arranged opposite each other on both sides of the support plate 21 along the Y direction. There are two upper sliding blocks 24, and the two upper sliding blocks 24 are slidably disposed in the two second sliding grooves 211 respectively. The two connecting rod assemblies 26 have connecting rods 263 extending along the Y direction, and each first rod body 261 and each second rod body 262 are hinged to the connecting rod 263 respectively.

[0059] Specifically, see Figure 3 A second connecting block 264 can be installed between the upper ends of the two second rods 262 as needed, with both ends of the second connecting block 264 hinged to the upper ends of the two second rods 262 respectively. A third connecting block 265 is installed between the lower ends of the two first rods 261, with both ends of the third connecting block 265 hinged to the lower ends of the two first rods 261 respectively. A thrust ball bearing 2651 is also installed on the third connecting block 265, with its inner circumference rotatably connected to the lead screw 251 and its outer surface connected to the third connecting block 265. The design of the second connecting block 264 and the third connecting block 265 enables the linear drive mechanism to more stably drive the first rods 261 and the second rods 262 to perform lifting and lowering actions. Furthermore, the thrust ball bearing 2651 can reduce the rigid contact and friction between the lead screw 251 and the third connecting block 265, allowing the lead screw 251 to rotate more smoothly.

[0060] Furthermore, the bottom of the lifting unit 2 is equipped with four casters (not shown in the figure). These can all be omnidirectional casters, or two fixed casters and two omnidirectional casters. Using this technical solution, maintenance personnel can flexibly adjust and change the position of the tooling as needed, making the maintenance process more convenient and labor-saving.

[0061] In one embodiment of this utility model, the support frame 3 is exemplary, made of carbon structural steel, preferably 45 steel. The base 41 and the support plate 21 are both made of aluminum alloy. The support frame 3 made of this material not only has high strength and hardness, capable of withstanding large loads, but is also easy to process and weld, offering balanced performance and relatively low cost. Furthermore, the aluminum alloy base 41 and support plate 21 make changing the tooling easier and more convenient for movement.

[0062] During maintenance, the replacement tool is first moved to a position below the eccentric device 1. The maintenance personnel set the output end of an electric wrench (not shown) onto the lead screw 251 and start the wrench. The lead screw 251, rotating mechanically, drives the first connecting block 232 to move along the X direction towards the third connecting block 265. The support plate 21 and support frame 3 rise under the action of the lifting unit 2. When the support frame 3 rises to the required position, the maintenance personnel loosen the locking bolt 42 and locking nut 43 and adjust the position of the support frame 3. When the two support frames 3 can respectively support the two bearing seats 13, the maintenance personnel tighten the locking bolt 42 and locking nut 43 and disassemble the eccentric device 1.

[0063] After disassembly, the screw 251 is driven to rotate in the opposite direction by an electric wrench. Under this mechanical rotation, the screw 251 moves the first connecting block 232 in the X direction away from the third connecting block 265. The support plate 21 and support frame 3 descend to their lowest position under the action of the lifting unit 2, allowing maintenance personnel to repair the eccentric device 1. After repair, the above steps are repeated to move the eccentric device 1 to the installation position and install it. The replacement fixture provided by this utility model has a simple structure and is easy to install. It can quickly replace the eccentric device, reduce the labor intensity of maintenance personnel, improve work efficiency, and eliminate safety hazards during the replacement process.

[0064] Although the present invention has been illustrated and described with reference to certain preferred embodiments, those skilled in the art should understand that the above description is a further detailed explanation of the present invention in conjunction with specific embodiments, and should not be construed as limiting the specific implementation of the present invention to these descriptions. Those skilled in the art can make various changes in form and detail, including some simple deductions or substitutions, without departing from the spirit and scope of the present invention.
