Abstract
Description
Technical Field
[0001] This application relates to the field of disassembly tools, and more specifically, to a device for disassembling ceramic bearings. Background Technology
[0002] Bearings are an important component in modern mechanical equipment. Their main function is to support rotating mechanical parts, reduce friction during their movement, and ensure their rotational accuracy. Ceramic bearings are widely used in mechanical equipment.
[0003] In related technologies, a spindle-ceramic bearing transmission structure is frequently used. The spindle and the ceramic bearing use an interference fit. When separating the spindle and the ceramic bearing, the interference fit needs to be released.
[0004] However, when disassembling damaged ceramic bearings on a shaft, the method of hammering is often used. This method of disassembling ceramic bearings often damages both the shaft and the bearing during the removal process, leading to the scrapping of both and increasing production costs. Therefore, a device for disassembling ceramic bearings is needed to solve the above problems. Summary of the Invention
[0005] In view of this, this application aims to provide a device for disassembling ceramic bearings, so as to solve the problem that the ceramic bearing and shaft are damaged when disassembling ceramic bearings in the related art.
[0006] To achieve the above objectives, this application provides a device for disassembling ceramic bearings, used to remove ceramic bearings from a spindle connected to the ceramic bearing. The device for disassembling ceramic bearings includes: a first clamping assembly for clamping the spindle; a second clamping assembly for clamping the ceramic bearing and capable of relative movement with respect to the first clamping assembly along the axial direction of the spindle; the second clamping assembly includes a fixed base, a first jaw, a second jaw, a first connecting rod, a second connecting rod, and a drive mechanism; the first jaw and the second jaw are arranged opposite to each other, and both the first connecting rod and the second connecting rod are rotatably connected to the fixed base; both ends of the first connecting rod are connected to the first jaw and the drive mechanism, respectively, and both ends of the second connecting rod are connected to the second jaw and the drive mechanism, respectively; when the drive mechanism drives the first connecting rod and the second connecting rod to rotate, it drives the first jaw and the second jaw to move towards each other to clamp the ceramic bearing, or drives the first jaw and the second jaw to move in opposite directions to release the ceramic bearing; both the first jaw and the second jaw are provided with clamping grooves that mate with the ceramic bearing; a displacement drive assembly is connected to the second clamping assembly to drive the second clamping assembly to reciprocate along the axial direction of the spindle.
[0007] During operation, the spindle containing the ceramic bearing is first clamped by the first clamping assembly to prevent the spindle from rotating or moving with the ceramic bearing during disassembly. The second clamping assembly moves to the position of the ceramic bearing, and the drive mechanism pushes the first and second connecting rods to rotate around the fixed seat, causing the first and second grippers to move towards each other. They then evenly contact the outer ring of the ceramic bearing through the clamping grooves, achieving symmetrical clamping. After clamping, the ceramic bearing is stably fixed by the second clamping assembly. Finally, the displacement drive assembly drives the second clamping assembly, carrying the clamped ceramic bearing, away from the first clamping assembly along the spindle axis. Because the spindle is restricted by the first clamping assembly and cannot move with the ceramic bearing, once the ceramic bearing has risen to a certain height, it can be completely separated from the spindle. At this point, the drive mechanism actuates again, opening the grippers and removing the ceramic bearing, thus completing the entire process of separating the ceramic bearing from the spindle. In the above technical solution, the ceramic bearing is subjected to two symmetrical clamping forces, and the resultant force passes through the center of the ceramic bearing, so no off-center load is generated; and the linkage mechanism is a pure mechanical transmission, with no sharp parts contacting the ceramic bearing. Combined with the smooth design of the clamping groove, the risk of damage can be reduced.
[0008] In some technical solutions, the drive mechanism may optionally include: a cylinder body disposed on a fixed seat; a piston disposed in the cylinder body, dividing the interior of the cylinder body into a first air chamber and a second air chamber; a telescopic rod, one end of which is connected to the piston, and the other end of which is connected to a first connecting rod and a second connecting rod; an air source, including a first air passage and a second air passage, the first air passage being connected to the first air chamber, and the second air passage being connected to the second air chamber; and a control valve disposed in the first air passage and the second air passage.
[0009] In the above technical solution, the piston rod is moved by the air pressure difference, which in turn drives the connecting rod to rotate, thus opening and closing the gripper. Compared with electric motors and hydraulic drives, the drive mechanism of this embodiment can precisely control the thrust by adjusting the pressure and flow rate of the air source, thereby avoiding damage to the ceramic bearing.
[0010] In some technical solutions, the cylinder block is optionally provided with a lifting lug; the displacement drive assembly has a detachable buckle, and the detachable buckle and the lifting lug are detachably fastened together.
[0011] In the above technical solution, the displacement drive assembly and the second clamping assembly are connected by the cooperation of the lifting lug and the loading and unloading buckle. The loading and unloading buckle (such as spring buckle) and the lifting lug can be directly fastened without bolts or welding, thus enabling convenient assembly and separation.
[0012] In some technical solutions, the second clamping assembly may optionally include a third link and a fourth link. The third link is rotatably mounted on the fixed base, and its two ends are respectively connected to the first link and the telescopic pull rod. The fourth link is rotatably mounted on the fixed base, and its two ends are respectively connected to the second link and the telescopic pull rod.
[0013] In the above technical solution, compared with single-bar transmission, the double-link structure can expand the opening and closing range of the gripper, and the telescopic link only needs to move a small distance to drive the gripper to move; at the same time, it can also improve the clamping force, thereby avoiding unstable clamping.
[0014] In some technical solutions, the displacement driving component optionally includes: a power source; a transmission mechanism, one end of which is connected to the power source and the other end of which is connected to a second clamping component.
[0015] In the above technical solution, on the one hand, the direction of power transmission can be changed by the transmission mechanism to adapt to the structural layout; on the other hand, the output of the power source can be changed by the transmission mechanism, thereby improving the control accuracy.
[0016] In some technical solutions, the transmission mechanism may optionally include: a drive shaft connected to a power source; a sprocket on the drive shaft; and a chain wound around the sprocket and connected to a second clamping assembly.
[0017] In the above technical solution, the chain and sprocket do not require high-precision alignment during installation, tension adjustment is simple, and they can be quickly replaced by cutting the old chain and splicing a new one after wear, thereby reducing long-term operating costs. Furthermore, the chain's flexibility absorbs the inertial impact of sudden loosening of the ceramic bearing, preventing damage from hard collisions; the slippage between the chain and sprocket under overload provides natural protection, preventing the power source from burning out, and is particularly suitable for the low-impact disassembly requirements of ceramic bearings.
[0018] In some technical solutions, the drive shaft may optionally also be provided with a bushing and a retaining ring, with the bushing and retaining ring located on both sides of the sprocket respectively.
[0019] In the above technical solution, axial limiting is achieved by setting bushings and retaining rings on both sides of the sprocket, thereby clamping the sprocket between the bushings and retaining rings on the drive shaft, allowing the sprocket to rotate only around the drive shaft. This ensures stable meshing between the chain and the sprocket, reducing vibration and impact, and protecting the ceramic bearings.
[0020] In some technical solutions, the displacement drive assembly may optionally include: a guide seat; the guide seat has a through hole through which the chain passes; and / or a speed reducer, disposed between the power source and the drive shaft.
[0021] In the above technical solution, due to the geometric constraints of the through hole, the chain can only slide axially, while lateral displacement is blocked by the through hole wall, thus avoiding slackness and vibration of the chain caused by its own weight, inertia, or external disturbances. This prevents chain misalignment from causing deviation in the movement direction of the second clamping assembly, and also reduces interference from the chain to other components. Simultaneously, by installing a reducer between the power source and the drive shaft, motion accuracy is improved, and the displacement drive assembly is protected, extending its service life.
[0022] In some technical solutions, the device for disassembling ceramic bearings may optionally include a frame; a displacement drive assembly is disposed at the top of the frame; and a first clamping assembly is disposed at the bottom of the frame.
[0023] In the above technical solution, by integrating the displacement drive component, the first clamping component and other components onto the frame, the device forms a stable integral structure, which not only avoids the layout chaos caused by the dispersion of components, but also connects the components into one unit through the frame design of the frame, thereby improving the convenience of overall movement and transfer, and thus meeting the flexible deployment needs between different workstations.
[0024] In some technical solutions, optionally, the bottom of the frame is provided with a positioning groove, and one end of the spindle extends into the positioning groove.
[0025] In the above technical solution, by setting a positioning groove, during disassembly, one end of the spindle can be inserted into the positioning groove first, which can achieve quick alignment and preliminary positioning of the spindle.
[0026] Additional aspects and advantages of the technical solutions of this application will become apparent in the following description or may be learned by practice of this application. Attached Figure Description

[0034] In related technologies, a spindle-ceramic bearing transmission structure is frequently used. The spindle and ceramic bearing employ an interference fit. When separating the spindle and ceramic bearing, the interference fit needs to be released. Currently, common methods for disassembling the spindle and ceramic bearing include hydraulic ejection, heating-assisted ejection, threaded ejection, manual hammering, and destructive disassembly. While each of these methods has its advantages, their core disadvantages are also clear, as shown in the table below:
[0035]
[0036] In view of this, this application aims to provide a device for disassembling ceramic bearings, so as to solve the problems of scratches or damage caused by uneven clamping force during the current mechanical disassembly of ceramic bearings.
[0037] The following is combined Figures 1 to 3 The present application provides a detailed description of a device for disassembling ceramic bearings through specific embodiments and application scenarios.
[0038] Reference Figure 1 , Figure 2 and Figure 3 This application provides a device for disassembling ceramic bearings, used to remove ceramic bearing 501 from a spindle 500 connected to ceramic bearing 501, the device comprising: a first clamping assembly 100, a second clamping assembly 200 and a displacement driving assembly 300.
[0039] The first clamping assembly 100 is used to clamp the spindle 500. The second clamping assembly 200 is used to clamp the ceramic bearing 501 and can move relative to the first clamping assembly 100 along the axial direction of the spindle 500; the second clamping assembly 200 includes a fixed base 210, a first jaw 220, a second jaw 230, a first connecting rod 240, a second connecting rod 250, and a drive mechanism 260; the first jaw and the second jaw are arranged opposite to each other, and both the first connecting rod 240 and the second connecting rod 250 are rotatably connected to the fixed base 210, and the two ends of the first connecting rod 240 are respectively connected to the first jaw 220 and the second connecting rod 250. The drive mechanism 260 is connected, and the two ends of the second connecting rod 250 are respectively connected to the second gripper 230 and the drive mechanism 260. When the drive mechanism 260 drives the first connecting rod 240 and the second connecting rod 250 to rotate, it drives the first gripper 220 and the second gripper 230 to move towards each other to clamp the ceramic bearing 501, or drives the first gripper 220 and the second gripper 230 to move in opposite directions to release the ceramic bearing 501. Both the first gripper 220 and the second gripper 230 are provided with clamping grooves 221 that cooperate with the ceramic bearing 501. The displacement drive assembly 300 is connected to the second clamping assembly 200 to drive the second clamping assembly 200 to reciprocate along the axial direction of the main shaft 500.
[0040] Specifically, the first clamping assembly 100 is used to clamp the spindle 500 where the ceramic bearing 501 to be disassembled is located, serving as a reference for fixing the entire device and preventing the spindle 500 from rotating or moving axially during disassembly, thereby ensuring accurate positioning in subsequent operations.
[0041] The second clamping assembly 200 is used to clamp the ceramic bearing 501 and separates the ceramic bearing 501 from the spindle 500 through its own axial movement (relative to the first clamping assembly 100), serving as the direct component for disassembly. The second clamping assembly 200 specifically includes a fixed base 210, a first jaw 220, a second jaw 230, a first connecting rod 240, a second connecting rod 250, and a drive mechanism 260. The fixed base 210 serves as the mounting base for the second clamping assembly 200, providing support and a mounting foundation. The first jaw 220 and the second jaw 230 directly contact and clamp the ceramic bearing 501, and both have clamping grooves 221 (such as an arc-shaped groove matching the outer ring of the ceramic bearing 501) on their inner sides, thereby increasing friction, dispersing clamping force, and preventing damage to the ceramic bearing 501. The first link 240 and the second link 250 act as transmission components, achieving synchronous opening and closing of the grippers through rotation. It is understood that the first link 240 and the second link 250 are symmetrically arranged to ensure the consistency of movement of the first gripper 220 and the second gripper 230. The drive mechanism 260 provides power to the links, indirectly controlling the opening and closing of the grippers by pushing or pulling the links to rotate around the fixed base 210. During clamping, the ceramic bearing 501 is subjected to two symmetrical clamping forces, the resultant force passing through the center of the ceramic bearing 501, preventing off-center loading. Furthermore, the linkage mechanism is a purely mechanical transmission, with no sharp parts contacting the ceramic bearing 501. Combined with the smooth design of the clamping groove 221, this reduces the risk of damage.
[0042] The displacement drive assembly 300 provides axial power to the second clamping assembly 200 to drive the second clamping assembly 200 to reciprocate along the axial direction of the spindle 500 (towards or away from the first clamping assembly 100), thereby generating the axial tension required for disassembly.
[0043] In the above embodiment, during operation, the spindle 500 containing the ceramic bearing 501 is first clamped by the first clamping assembly 100 to prevent the spindle 500 from rotating or moving with the ceramic bearing 501 during disassembly. The second clamping assembly 200 moves to the position of the ceramic bearing 501, and the drive mechanism 260 pushes the first connecting rod 240 and the second connecting rod 250 to rotate around the fixed base 210, thereby causing the first jaw 220 and the second jaw 230 to move towards each other. Through the clamping groove 221, they uniformly contact the outer ring of the ceramic bearing 501 to achieve symmetrical clamping. After clamping, the ceramic bearing 501 is stably fixed by the second clamping assembly 200. Finally, the displacement drive assembly 300 drives the second clamping assembly 200 to move the clamped ceramic bearing 501 away from the first clamping assembly 100 along the axial direction of the main shaft 500. Since the main shaft 500 is restricted by the first clamping assembly 100, it cannot move together with the ceramic bearing 501. Therefore, when the ceramic bearing 501 rises to a certain height, the ceramic bearing 501 and the main shaft 500 can be completely separated. At this time, the drive mechanism 260 is activated again to open the gripper and remove the ceramic bearing 501, thus completing the entire process of separating the ceramic bearing 501 from the main shaft 500.
[0044] In some embodiments, to prevent damage to the ceramic bearing 501, the clamping surfaces of the first jaw 220 and the second jaw 230 are provided with flexible elements. The flexible elements can deform slightly under pressure, thereby adapting to minor unevenness on the surface of the ceramic bearing 501 and avoiding localized stress concentration; simultaneously, it can reduce sliding friction during relative movement between the jaws and the ceramic bearing 501, preventing abrasive scratches. For example, the flexible elements can be made of rubber or plastic.
[0045] Reference Figure 1 and Figure 2 In some embodiments, the drive mechanism 260 includes a cylinder 261, a piston 262, a telescopic rod 268, an air source 265, and a control valve 266.
[0046] The cylinder body 261 is mounted on the fixed base 210. The piston 262 is disposed within the cylinder body 261, dividing the interior of the cylinder body 261 into a first air chamber 263 and a second air chamber 264. One end of the telescopic rod 268 is connected to the piston 262, and the other end is connected to the first connecting rod 240 and the second connecting rod 250. The air source 265 includes a first air passage 2651 and a second air passage 2652. The first air passage 2651 communicates with the first air chamber 263, and the second air passage 2652 communicates with the second air chamber 264. A control valve 266 is disposed in both the first air passage 2651 and the second air passage 2652.
[0047] Specifically, cylinder 261 is fixed to mounting base 210 and has an internal cavity. Piston 262 is disposed within the cavity, which is divided into a first air chamber 263 and a second air chamber 264. Thus, by controlling the pressure difference between the first air chamber 263 and the second air chamber 264, piston 262 can be moved. Telescopic rod 268 is connected at one end to piston 262 and at the other end to first connecting rod 240 and second connecting rod 250, thereby converting the linear motion of piston 262 into rotation of the connecting rods, indirectly controlling the opening and closing of the grippers. Air source 265 supplies air to the first air chamber 263 and the second air chamber 264 through two independent air passages, creating a pressure difference that drives piston 262. Control valve 266 is installed on the first air passage 2651 and the second air passage 2652, switching the air passage on / off and the flow rate via electromagnetic signals.
[0048] In the above embodiments, the piston 262 is moved by the air pressure difference, which in turn drives the connecting rod to rotate, thereby opening and closing the gripper. Compared with electric motor and hydraulic drive, the drive mechanism 260 of this application embodiment can precisely control the thrust by adjusting the pressure and flow rate of the air source 265, thereby avoiding damage to the ceramic bearing 501.
[0049] In practical applications, the cylinder head of cylinder block 261 and piston 262 are sealed by a dynamic sealing ring, and the telescopic rod 268 and piston 262 are sealed by an O-ring. The telescopic rod 268 and cylinder block 261 are sealed by two pressure rings of different sizes and a star-shaped sealing ring.
[0050] The mounting base 210 includes a first plate, a second plate, and a third plate, which are connected together by screws and nuts.
[0051] In some embodiments, the cylinder body 261 is provided with a lifting lug 267; the displacement drive assembly 300 has a detachable buckle 310, which is detachably fastened to the lifting lug 267.
[0052] In practical applications, the displacement drive assembly 300 and the second clamping assembly 200 are connected by the cooperation of the lifting lug 267 and the loading and unloading buckle 310. The loading and unloading buckle 310 (such as a spring buckle) and the lifting lug 267 can be directly fastened without bolts or welding, thus enabling convenient assembly and separation.
[0053] Reference Figure 1 and Figure 3In some embodiments, the second clamping assembly 200 further includes a third link 270 and a fourth link 280. The third link 270 is rotatably mounted on the fixed base 210, and its two ends are respectively connected to the first link 240 and the telescopic pull rod 268. The fourth link 280 is rotatably mounted on the fixed base 210, and its two ends are respectively connected to the second link 250 and the telescopic pull rod 268.
[0054] In practical applications, by adding a third link 270 and a fourth link 280, which cooperate with the first link 240 and the second link 250 respectively, a two-stage linkage transmission is formed. Specifically, the movement of the first gripper 220 is driven by the telescopic rod 268-third link 270-first link 240 transmission, while the movement of the second gripper 230 is driven by the telescopic rod 268-fourth link 280-second link 250. Compared to a single-link transmission, the double-link structure can expand the opening and closing range of the grippers; the telescopic link only needs to move a small distance to move the grippers. Simultaneously, it can also increase the clamping force, thereby avoiding clamping instability.
[0055] In some embodiments, the displacement drive assembly 300 includes a power source 320 and a transmission mechanism 330. One end of the transmission mechanism 330 is connected to the power source 320, and the other end is connected to the second clamping assembly 200.
[0056] In this way, on the one hand, the direction of power transmission can be changed through the transmission mechanism 330 to adapt to the structural layout; on the other hand, the output of the power source 320 can be changed through the transmission mechanism 330, thereby improving the control accuracy.
[0057] It is understandable that the power source 320 can be an electric motor or motor, etc.
[0058] In practical applications, the transmission mechanism 330 includes a transmission shaft 331 and a chain 333. The transmission shaft 331 is connected to the power source 320; a sprocket 332 is provided on the transmission shaft 331. The chain 333 is wound around the sprocket 332 and connected to the second clamping assembly 200.
[0059] First, the chain 333 and sprocket 332 do not require alignment during installation, and tension adjustment is simple. After wear, they can be quickly replaced by cutting the old chain and splicing a new one, thus reducing long-term operating costs. Furthermore, the flexible nature of the chain 333 can absorb the inertial impact when the ceramic bearing 501 suddenly loosens, avoiding damage from hard collisions.
[0060] In the above embodiment, the drive shaft 331 is also provided with a bushing 334 and a retaining ring 335, with the bushing 334 and the retaining ring 335 located on both sides of the sprocket 332 respectively.
[0061] In practical applications, the sprocket 332 is mounted on the drive shaft 331. If relying solely on the engagement between the drive shaft 331 and the sprocket 332, the sprocket 332 is prone to axial movement along the drive shaft 331 under the tension of the chain 333 or the centrifugal force of rotation. This axial movement can easily lead to chain 333 engagement failure and decreased motion accuracy, thus affecting the smoothness of disassembling the ceramic bearing 501. Therefore, in this embodiment, axial limiting is achieved by providing bushings 334 and retaining rings 335 on both sides of the sprocket 332, thereby clamping the sprocket 332 between the bushings 334 and the retaining rings 335 on the drive shaft 331, allowing the sprocket 332 to rotate only around the drive shaft 331. This ensures stable engagement between the chain 333 and the sprocket 332, thereby reducing vibration and impact and protecting the ceramic bearing 501.
[0062] In some embodiments, the displacement drive assembly 300 further includes a guide seat 340; the guide seat 340 is provided with a through hole 341, and the chain 333 passes through the through hole 341.
[0063] In practical applications, when the chain 333 passes through the through hole 341 under power drive, due to the geometric constraints of the through hole 341, the chain 333 can only slide axially, while lateral displacement is blocked by the wall of the through hole 341. This avoids slackness and vibration of the chain 333 caused by its own weight, inertia, or external disturbances. In this way, on the one hand, it can prevent the movement direction of the second clamping assembly 200 from deviating due to chain misalignment, and on the other hand, it can also reduce the interference of the chain 333 on other components.
[0064] In some embodiments, the displacement drive assembly 300 further includes a speed reducer 350. The speed reducer 350 is disposed between the power source 320 and the drive shaft 331.
[0065] In the above embodiment, by setting a reducer 350 between the power source 320 and the drive shaft 331, on the one hand, the motion accuracy can be improved, and on the other hand, the displacement drive assembly 300 can be protected and its service life extended.
[0066] In some embodiments, the apparatus for disassembling ceramic bearings further includes a frame 400; a displacement drive assembly 300 is disposed on the top of the frame 400; and a first clamping assembly 100 is disposed on the bottom of the frame 400.
[0067] By integrating the displacement drive component 300, the first clamping component 100, and other components onto the frame 400, the device forms a stable integral structure. This avoids the layout chaos caused by the dispersion of components, and the frame design of the frame 400 connects the components into one, thereby improving the convenience of overall movement and transfer, and thus meeting the flexible deployment needs between different workstations.
[0068] In practical applications, the first clamping assembly 100 includes a first clamping part and a second clamping part, which are arranged opposite to each other on both sides of the frame 400 and are detachably connected to the frame 400. In practical applications, the frame 400 has multiple arrays of mounting holes along the horizontal direction on both sides. This allows the relative distance between the first and second clamping parts to be adjusted by changing their mounting positions, thereby achieving clamping and fixing of the spindle 500.
[0069] In some embodiments, the bottom of the frame 400 is provided with a positioning groove 401, and one end of the spindle 500 extends into the positioning groove 401.
[0070] In the above embodiment, by setting a positioning groove 401, during disassembly, one end of the spindle 500 is first inserted into the positioning groove 401, which can achieve quick alignment and preliminary positioning of the spindle 500.
