Description

Technical Field

[0001] This utility model relates to the field of mechanical tooling, specifically to a bearing auxiliary disassembly and assembly device. Background Technology

[0002] In industrial production, bearings are often required to be installed onto shaft parts using an interference fit. Existing installation methods generally employ either heat fitting or direct hammering. Heat fitting can easily lead to localized deformation of the bearing and cause annealing of the bearing steel, resulting in a decrease in hardness. On the other hand, hammering installation makes it difficult to ensure proper alignment between the bearing and the shaft part, which can easily lead to damage or breakage of the bearing or the installed shaft part. Furthermore, both of these commonly used methods are cumbersome and inefficient.

[0003] Therefore, there is a need to provide a bearing-aided disassembly and assembly device to improve the convenience of bearing installation. Utility Model Content

[0013] Preferably, it also includes a bearing removal mechanism for removing the bearing from the workpiece;

[0014] The second installation area is provided with a worktable that can move radially along the workpiece. The worktable has at least two stations, which are used to install the bearing disassembly mechanism and the bearing installation mechanism. Based on the movement of the worktable, the station that works in conjunction with the workpiece can be switched.

[0015] Preferably, the bearing disassembly mechanism includes a connecting arm and a limiting member. The limiting member is sleeved on the workpiece through an opening and is located on the side of the bearing away from the second mounting area.

The connecting arm is used to connect the limiting member and the drive unit.

[0016] Preferably, the bearing disassembly mechanism further includes a second centering member, which is used to center and cooperate with the workpiece.

[0028] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0029] Figure 1 This is a schematic diagram of the overall structure of the bearing auxiliary disassembly and assembly equipment provided in this embodiment of the utility model; Figure 2 This is a schematic diagram of the bearing installation mechanism of the bearing auxiliary disassembly and assembly equipment provided in this embodiment of the utility model.

[0030] like Figure 1 and Figure 2 As shown, this utility model embodiment provides a bearing auxiliary disassembly and assembly device, including a frame 1. The frame 1 has a first mounting area 11 and a second mounting area 12 arranged adjacent to each other. The first mounting area is used to install a workpiece 2, and the second mounting area is used to install a bearing mounting mechanism 3 and a drive unit 6. The bearing mounting mechanism 3 includes a first centering member 31 and an outer sleeve 32. The first centering member 31 can be aligned and cooperate with the workpiece 2. The bearing 5 and the outer sleeve 32 are both axially movably sleeved on the first centering member 31, and the outer sleeve 32 is located on the side of the bearing 5 away from the workpiece 2. The drive unit 6 is used to drive the outer sleeve to move axially.

[0031] Among them, Figure 1In the embodiment shown, the first mounting area 11 is located in the middle of the frame 1, and the second mounting area 12 is located at both ends of the frame 1, so that after the workpiece 2 is installed in the first mounting area 11, both ends of it can be mounted with bearings through the bearing mounting mechanism 3 provided on the second mounting area 12, which improves the convenience of use; in some other embodiments, the first mounting area 11 and the second mounting area 12 can also be arranged in other ways, as long as it can ensure that the bearing mounting mechanism 3 can work smoothly with the workpiece 2, which will not be elaborated here.

[0032] When it is necessary to install the bearing onto the workpiece 2, the workpiece 2 is installed in the first installation area 11, the bearing installation mechanism 3 is installed in the second installation area 12, and the first centering member 31 is aligned with the workpiece 2. Then, the drive unit 6 is activated to drive the outer sleeve 32 to move axially along the first centering member 31, and further push the bearing 5 on the first centering member 31 toward the workpiece 2 until the bearing 5 is detached from the first centering member 31 and fitted onto the workpiece 2. Throughout the process, the first centering member 31 and the workpiece 2 remain concentric, so the bearing 5 fitted onto the first centering member 31... While maintaining concentricity with workpiece 2, the outer sleeve 32 is driven by the drive unit 6 to move axially along the first centering piece 31. Therefore, the vector direction of the force exerted by the outer sleeve 32 on the bearing 5 is parallel to the axis of workpiece 2, so that the bearing 5 moves coaxially with workpiece 2 and moves upward along the axis of workpiece 2. Thus, the bearing 5 can be stably fitted onto workpiece 2, avoiding scratches, deformation or even breakage caused by strong interference between the bearing 5 and workpiece 2 due to misalignment. This improves the stability of bearing installation, and the whole process also significantly improves the installation speed compared to existing hot fitting methods.

[0033] The drive unit 6 can be a cylinder, hydraulic cylinder, or linear motor, or other device capable of outputting axial power. The drive unit 6 can also be other existing technologies, which will not be elaborated here.

[0034] It should also be noted that, during actual design and processing, the first centering part 31 and the bearing 5 are preferably clearance fits, and the workpiece 2 and the bearing 5 are preferably transition fits or interference fits (the fit between the workpiece and the bearing is determined according to the process requirements). This ensures that the bearing 5 moves smoothly on the first centering part 31 and also ensures the accuracy of the relative position of the bearing 5 and the workpiece 2 during assembly.

[0035] In addition, the frame 1 of this utility model is provided with a second installation area 12 on both sides. That is, if bearings need to be installed at both ends of the workpiece 2, the bearing installation mechanism 3 can be installed in both second installation areas 12, and the bearings can be installed at both ends of the workpiece 2 at the same time. The specific installation process is the same as the process when installing alone, and will not be described in detail here.

[0036] Figure 3a , Figure 3b as well as Figure 3c This is a schematic diagram illustrating the working principle of the bearing installation mechanism of the bearing auxiliary disassembly and assembly equipment provided in this embodiment of the utility model.

[0037] like Figure 3a , Figure 3b as well as Figure 3c As shown, in one preferred embodiment, the workpiece 2 has a centering hole 21, and the first centering member 31 has a centering tightening part 311 at one end near the workpiece 2. The centering hole 21 and the centering tightening part 311 are aligned and fitted together through the cooperation of the centering hole 21 and the centering tightening part 311. The centering hole 21 and the centering tightening part 311 can be as shown in Figure 3 and... Figure 4 The tapered holes and tapered protrusions shown are designed to fit together. Since shaft parts generally require centering holes on their round end faces to ensure the accuracy of the rotary machining, the machining cost can be reduced by using the existing centering hole 21 on the workpiece 2 for bearing installation. The centering hole 21 and the centering clamping part 311 can also adopt other fitting methods, as long as the centering of the first centering part 31 and the workpiece 2 can be guaranteed. This will not be elaborated here.

[0038] like Figure 3a As shown, in one preferred embodiment, when the first centering member 31 is aligned with the workpiece 2, the centering clamping part 311 is located inside the centering hole 21, and the end faces of the first centering member 31 and the workpiece 2 abut against each other. Therefore, when the bearing 5 moves from the first centering member 31 to the workpiece 2, the inner ring of the bearing 5 always mates with the first centering member 31 or the workpiece 2, which can maintain its position and improve the stability of the bearing 5 installation.

[0039] like Figure 3b As shown, a plurality of axially extending relief grooves 312 are provided on the outer peripheral surface of the first centering member 31. By providing relief grooves 312, it is possible to ensure good mutual cooperation and positioning between the first centering member 31 and the bearing 5, and to ensure the smooth movement of the bearing 5 on the first centering member 31.

[0040] The clearance slot 312 can be as follows Figure 3b The semi-circular groove extending axially along the first centering member 31 shown can also be a groove of other shapes; or, the first centering member 31 can be machined into a shape inscribed in the bearing 5, for example, machined into an inscribed regular hexagon of the bearing 5, etc., as long as it can restrict the degree of freedom of the bearing 5 in radial movement and ensure that the bearing 5 can move smoothly in the first centering member 31 in the axial direction, which will not be elaborated here.

[0041] like Figure 3cAs shown, in one preferred embodiment, a compression spring 33 is provided at the end of the first centering member 31 inside the outer sleeve 32 away from the workpiece 2. The compression spring 33 is used to apply a force to the first centering member 31 to press against the workpiece 2, such as... Figure 3c As shown, the end of the outer sleeve 32 away from the first centering member 31 is a closed bottom surface. The compression spring 33 is disposed between the bottom surface and the first centering member 31. In this way, when the drive unit 6 drives the outer sleeve 32 to move towards the workpiece 2, the compression spring 33 applies a force to the first centering member 31 to press against the workpiece 2, thereby ensuring that the first centering member 31 and the workpiece 2 are always in a state of alignment and cooperation, and improving the stability of the bearing installation.

[0042] Furthermore, such as Figure 3c As shown, an outer protrusion 313 can be provided at one end of the first centering member 31, and an inner protrusion 321 can be provided at one end of the sleeve 32. The outer diameter of the outer protrusion 313 is larger than the inner diameter of the inner protrusion 321, so that the first centering member 31 will not fall out of the sleeve 32 when the bearing mounting mechanism 3 is placed normally, which makes it easier to install and use the equipment.

[0043] It should also be noted that, in Figure 3c In the illustrated embodiment, the outer sleeve 32 has an end face at the end away from the first centering member 31. A compression spring 33 is disposed between the end faces of the first centering member 31 and the outer sleeve 32. When the driving unit 6 drives the outer sleeve 32 to move towards the workpiece, the compression spring 33 can apply sufficient force to the first centering member 31 towards the workpiece 2, ensuring a stable alignment between them. Alternatively, the outer sleeve 32 can also be a sleeve-shaped structure with a through-hole, and the compression spring 33 can be located between the first centering member 31 and the output end of the driving unit 6. The compression spring 33 can also apply sufficient clamping force to the first centering member 31. In some other embodiments, the compression spring can also push the first centering member 31 towards the workpiece 2 in other ways. The specific arrangement can be adjusted according to the actual situation, and will not be elaborated here.

[0044] In addition, the first centering component 31 can have various specifications. The outer diameter of each first centering component 31 is different, or the size of the centering and tightening part 311 provided on the first centering component 31 is different. It can be used for the assembly of workpieces and bearings of various sizes, thereby improving the applicability of this device. The outer sleeve 32 should have various specifications corresponding to the first centering component 31, which will not be elaborated here.

[0045] like Figure 2As shown, in one preferred embodiment, a sliding connecting plate 14 is fixedly installed on the second mounting area 12. A guide rail 142 is provided on the sliding connecting plate 14. The extension direction of the guide rail 142 is parallel to the axial direction of the workpiece 2. The mounting bracket 13 is slidably mounted on the guide rail 142 via a slider 15. The mounting bracket 13 is used to install the bearing mounting mechanism 3. The slider 15 and the sliding connecting plate 14 are provided with mutually cooperating pins 151 and insertion holes 141. The insertion holes 141 are distributed at intervals along the axial direction of the workpiece 2 on the sliding connecting plate 14. After the pins 151 are removed from the insertion holes 141, the slider 15 and the mounting bracket 13 can reciprocate along the guide rail 142. After the pins 151 are inserted into the insertion holes 141, the slider 15 and the mounting bracket 13 are locked on the sliding connecting plate 14.

[0046] Through the cooperation of slider 15 and guide rail 142, mounting bracket 13 and bearing mounting mechanism 3 mounted on mounting bracket 13 reciprocate along the axial direction of workpiece 2 in the second mounting area 12. In this way, when bearing mounting mechanism 3 needs to work, mounting bracket 13 can be placed close to workpiece 2, which makes it easier to align and install the first centering piece 31 with workpiece 2. After the bearing is installed, mounting bracket 13 can be placed away from workpiece 2, which makes it easier for workers to pick up workpiece 2 and replace other workpieces for bearing installation.

[0047] Furthermore, the mounting bracket 13 and the bearing mounting mechanism 3 are designed to reciprocate along the axial direction of the workpiece 2, making the bearing auxiliary disassembly and assembly equipment provided by this utility model applicable to workpieces 2 of various lengths. Specifically, when the workpiece 2 is long, the mounting bracket 13 can be moved away from the first mounting area 11, and when the workpiece 2 is short, the mounting bracket 13 can be moved closer to the first mounting area 11, thereby improving the applicability of the bearing auxiliary disassembly and assembly equipment.

[0048] Figure 4 This is a schematic diagram of the bearing disassembly mechanism of the bearing auxiliary disassembly and assembly equipment provided in this embodiment of the utility model; Figure 5a and Figure 5b This is a structural schematic diagram of the connecting arm and limiting component of the bearing auxiliary disassembly and assembly equipment provided in this embodiment of the utility model.

[0049] like Figure 1 , Figure 4 , Figure 5a and Figure 5b As shown, in one preferred embodiment, a bearing disassembly mechanism 4 can also be installed in the second mounting area 12. The bearing disassembly mechanism 4 includes a connecting arm 41 and a limiting member 42. The limiting member 42 is sleeved on the workpiece 2 through an opening and is located on the side of the bearing 5 away from the second mounting area 12. The inner diameter of the opening of the limiting member 42 is larger than the outer diameter of the workpiece 2 and smaller than the maximum diameter of the bearing 5. The connecting arm 41 is used to connect the limiting member 42 and the drive unit 6.

[0050] When it is necessary to remove the bearing 5 from the workpiece 2, the connecting arm 41 is first driven by the drive unit 6 to be positioned as follows: Figure 4 At the position shown, a limiting member 42 is then installed between the connecting arm 41 and the bearing 5 on the workpiece 2. The connecting arm 41 is then driven to move toward the limiting member 42 by the driving unit 6, so that the limiting member 42 pushes the bearing 5 away from the workpiece 2.

[0051] Limiting component 42 can be as follows Figure 5b The single-sided opening structure shown is fitted onto the workpiece 2 through the opening. The opening has a straight section and an arc section. The inner diameter of the arc section of the limiting member 42 opening is the same as the outer diameter of the workpiece 2. When the limiting member 42 is fitted onto the workpiece 2, it can cooperate with the workpiece 2. The outer circumferential surface limits the movement of the limiting member 42, so that the limiting member 42 can move along the axial direction of the workpiece 2 after being subjected to the force of the connecting arm 41. This allows a uniform force to be applied to each position of the circular end face of the bearing 5, ensuring the safety and stability when the bearing is removed.

[0052] like Figure 4 As shown, the bearing disassembly mechanism 4 also includes a second centering member 43, which is used to center and install with the workpiece 2. The second centering member 43 is installed at the movable end of the drive unit, and the connecting arm 41 is connected to the fixed end of the drive unit 6. After the connecting arm 41, the limiting member 42 and the second centering member 43 are installed in place, the pin 151 of the slider 15 is pulled out from the insertion hole 141. At this time, the drive unit 6 is started, and the second centering member 43 is pushed towards the workpiece 2. Since the workpiece 2 is fixed on the frame 1, the fixed end of the drive unit 6, the connecting frame 13 and the connecting arm 41 move away from the workpiece 2 under the action of the reaction force, so that the connecting arm 41 and the limiting member 42 remove the bearing 5 on the workpiece 2.

[0053] exist Figure 4 In the illustrated embodiment, the fixed end of the drive unit 6 is fixedly mounted on the connecting frame 13, and the connecting arm 41 is also fixedly connected to the connecting frame 13, that is, the connecting arm 41 is fixedly connected to the fixed end of the drive unit 6; as shown Figure 5a As shown, the connecting arm 41 includes a locking position 413 for cooperating with the limiting member 42, a quick-release hole 412 for quickly assembling and disassembling the connecting block 131 on the connecting frame 13, and an arm body 411 for connecting the locking position 413 and the quick-release hole 412. The specific structure of the connecting arm 41 and the specific cooperation method between the connecting arm and the limiting member, the connecting frame (or the fixed end of the drive unit) can be adapted according to the actual processing needs, and will not be elaborated here.

[0054] Furthermore, such as Figure 2 , Figure 4 and Figure 5aAs shown, the quick-connect hole 412 has a T-shaped inner hole, and the connecting block 131 has a T-shaped outer contour. When the quick-connect hole 412 is installed into the connecting block 131, the two cooperate to fix the connecting block 131 (connecting bracket 13) and the quick-connect hole 412 (connecting arm 41) relative to each other along the axial direction of the workpiece 2, so that the bearing disassembly can be carried out smoothly. The quick-connect hole 412 and the connecting block 131 can be other shapes and have other cooperation methods, as long as they can ensure that the connecting arm 41 and the connecting bracket 13 are relatively fixed along the axial direction of the workpiece 2 after they are cooperated. This will not be elaborated here.

[0055] The limiting member 42 can have various specifications. The opening size of the limiting member 42 of various specifications is different, while the external contour size of the limiting member 42 of various specifications is the same. By setting the limiting member 42 of various specifications, its opening can be adapted to different disassembly scenarios of workpiece 2 and bearing 5.

[0056] In addition, protective mechanisms can be provided at both ends of the connecting arm 41. Since the connecting arm 41 and the limiting member 42 generally require a large axial force to be applied to the bearing 5 when pulling it away from the workpiece 2, the connecting arm 41 will also be subjected to a large reaction force, potentially causing it to bend and deform and open to both sides. By providing protective mechanisms, the connecting arm 41 can be limited, preventing it from deforming or bending away from the workpiece 2, thus improving the stability of bearing removal. The protective mechanism can be a reinforcing frame structure fitted onto the two connecting arms 41 and engaging with the two mutually distant end faces of the connecting arms 41, or other structures capable of achieving the above functions.

[0057] Combination Figure 2 and Figure 4 An adapter plate 7 is provided at the movable end of the drive unit 6. The adapter plate 7 is used to install the first centering part 31 and the outer sleeve 32 of the bearing mounting mechanism 3, as well as the second centering part 43 of the bearing disassembly mechanism 4. When switching the bearing mounting (disassembly) function of the device, it is only necessary to install the corresponding parts on the adapter plate 7 (when disassembling, the connecting arm 41 needs to be installed on the connecting block 131 of the connecting frame 13). The switching of the device function is faster and the convenience of using the device is improved.

[0058] It should be noted that the bearing auxiliary installation and removal equipment provided by this utility model has second installation areas 12 on both sides of the first installation area 11. A connecting frame 13 is mounted on the second installation area 12 via a sliding connecting plate 14. The fixed end of the drive unit 6 is fixedly mounted on the connecting frame 13, and the movable end of the drive unit 6 is mounted on an adapter plate 7. By changing the type of components mounted on the adapter plate 7 and by installing or removing the connecting arm 41 from the connecting frame 13, the function of the second installation area 12 can be flexibly switched. In practical applications, whether the two second installation areas 12 are specifically used for installing bearing installation mechanisms or bearing removal mechanisms can be adjusted according to production needs, which will not be elaborated here.

[0059] In addition, in one preferred embodiment, a worktable that can move radially along the workpiece 2 is provided on the second installation area 12. The worktable has at least two stations for installing the bearing disassembly mechanism and the bearing installation mechanism. Based on the movement of the worktable, the station that works in conjunction with the workpiece can be switched.

[0060] For example, in a specific embodiment, the movement direction of the worktable is parallel to the horizontal plane, that is, parallel to the diameter of the workpiece 2 along the horizontal direction, and a locking mechanism for locking the movement of the worktable is provided on the second mounting area 12. The worktable has two stations, and the above-mentioned bearing mounting mechanism 3 and bearing disassembly mechanism 4 are respectively installed on the two stations.

[0061] When the worktable moves to its leftmost position, it is locked by a locking mechanism. At this point, the axis of the first centering member 31 of the bearing installation mechanism 3 on the right-hand station roughly coincides with the axis of the workpiece 2, thus enabling the bearing installation. When the worktable moves to its rightmost position, it is locked by a locking mechanism. At this point, the axis of the second centering member 43 of the bearing disassembly mechanism 4 on the left-hand station roughly coincides with the axis of the workpiece 2, thus enabling the bearing disassembly. Drive units can be installed on both stations, or the same drive unit can drive the movements of both stations. The specific configuration of the drive units can be adapted by the designers or operators, and will not be elaborated here.

[0062] Figure 6 This is a schematic diagram of the structure of the floating support mechanism improved in this embodiment of the utility model.

[0063] like Figure 6As shown, in one preferred embodiment, a floating support mechanism 8 is provided on the first mounting area 11, and the workpiece 2 is mounted on the floating support mechanism 8. When the first centering member 31 approaches the workpiece 2, the workpiece 2 can float radially, allowing the workpiece 2 and the first centering member 31 to be smoothly aligned and engaged. Due to precision issues during the manufacturing process of the workpiece 2, or due to bending deformation during long-term use, the overall coaxiality of the workpiece is inevitably poor. When the workpiece 2 is placed on the frame, it is difficult to completely align it with the first centering member 31. Therefore, by setting the workpiece 2 to float radially, and through the cooperation of the first centering member 31 and the workpiece 2, after driving the workpiece 2 to move radially by a certain amplitude, the first centering member 31 can be aligned with the workpiece 2, making it easier to use.

[0064] The floating support mechanism 8 can be a cylinder floating support, with the cylinder's support force set just enough to support the workpiece 2 to a position near the centering position of the first centering member 31. The support medium inside the cylinder is a highly compressible gas. Therefore, when the first centering member 31 moves towards the workpiece 2, for example, through the cooperation of the aforementioned centering clamping part and centering hole, the first centering member 31 drives the workpiece 2 to move radially until the two are aligned. The floating support mechanism 8 can also use other flexible support methods such as spring support. As long as the workpiece 2 can move smoothly and cooperate with the first centering member 31 after the first centering member 31 applies a radial force to the workpiece 2, it is acceptable.

[0065] Furthermore, in Figure 6 In the embodiment shown, the floating support mechanism 8 includes a first support frame 81, which is fixedly connected to the frame 1 via an upper connecting arm 812 and a lower connecting arm 813. A second support frame 82 is fixedly installed on one side of the first support frame 81. The second support frame 82 is a cylinder, and the output end of the cylinder is a second support block 821. The second support frame 82 serves as a pneumatic support, enabling the workpiece 2 and the first centering component 31 to be smoothly aligned and cooperated.

[0066] A third support frame 83 is provided on the first support frame 81, wherein a first support block 811 and a third support block 831 are respectively provided. The first support block 811 is used to place the workpiece 2 initially so that the workpiece 2 is in a suitable position. When the air pressure of the second support frame 82 increases, the second support block 821 moves upward, and the second support block 821 can smoothly cooperate with the workpiece 2, improving the convenience of use.

[0067] The radial positions of the third support block 831 and the third support frame 83 along the workpiece 2 can be adjusted by adjusting the screw 832. Specifically, the third support frame 83 has a groove that matches the size of the third support block 831, so that... Figure 6The third support block 831 can only move up and down or back and forth along the groove of the third support frame 83 (the back and forth direction is the axial direction of the workpiece). The top of the third support frame 83 is also provided with an inner hole for the adjusting screw 832 to pass through. After the adjusting screw 832 passes through the inner hole, it is threadedly engaged with the third support block 831. When the adjusting screw 832 is rotated, the third support block 831 can move up and down along the groove of the third support frame 83.

[0068] By adjusting the position of the third support block 831, when the air pressure of the second support frame 82 increases, the second support block 821 and the third support block 831 can clamp the workpiece 2 to achieve pre-fixation of the workpiece 2, which makes it easier for the first centering piece 31 to center and cooperate with the workpiece 2 in the future.

[0069] In one embodiment, the first support block 811, the second support block 821, and the third support block 831 are all V-shaped blocks. Similar to the third support block 831, the relative position of the first support block 811 and the first support frame 81 is adjustable. Initially, the first support block 811 and the third support block 831 are adjusted to a suitable height, the workpiece 2 is placed on the first support block 811, and the cylinder of the second support frame 82 is activated to pre-fix the workpiece with the second support block 821 and the third support block 831. Then, the drive unit 6 is activated to move the first centering member 31 toward the workpiece. During the centering and mating process of the first centering member 31 and the workpiece 2, the position of the second support block 82 can be adjusted by adjusting the screw 832 so that after the first centering member 31 and the workpiece 2 are mated, the upper part of the workpiece 2 is close to the third support block 831. Then, the third support block 831 is fixed and the first support block 811 is adjusted so that the first support block 811 and the third support block 831 clamp the workpiece in this position, which can improve the stability during the subsequent bearing installation process.

[0070] Alternatively, the floating support mechanism 8 can also be a spring support mechanism provided on the first mounting area 11. When the workpiece 2 is placed above the spring support mechanism, the axis of the workpiece 2 is approximately aligned with the axis of the first centering member 31 or the second centering member 43. When the first centering member 31 or the second centering member 43 moves towards the workpiece 2, the workpiece 2 can float on the spring support mechanism, allowing the workpiece 2 to be smoothly aligned and engaged with the centering member. In some other embodiments, the workpiece 2 or the bearing mounting mechanism 3, bearing disassembly mechanism 4, etc., can also be driven radially in other ways to ensure that the workpiece 2 can be smoothly aligned and engaged with the centering member. The specific structure and method can be adjusted according to the actual situation, and will not be elaborated here.

[0071] It should also be noted that, in Figure 1In the illustrated embodiment, by controlling the design precision of each component, and although the diameters of the workpieces 2 are different, the workpieces 2 are always placed in the center of the first mounting area 11. Therefore, the axes of the workpieces 2, the first centering member 31, and the second centering member 43, etc., installed in the first mounting area 11 and the second mounting area 12 are aligned in their left and right directions (i.e., Figure 1 The width direction of the frame is aligned, but as the diameters of components such as workpiece 2 and the first centering piece 31 change, their axes in the height direction (i.e., Figure 1 The height of the frame changes in the vertical direction, but remains constant in the left and right directions. Therefore, by simply adjusting the height of the workpiece 2 vertically through the floating support mechanism 8, and thus adjusting the axial height of the workpiece 2, it is sufficient to achieve smooth alignment and cooperation between the workpiece 2 and the centering part, ensuring the smooth operation of the equipment.

[0072] In some other embodiments, the workpiece 2 or the bearing mounting mechanism 3 and the bearing disassembly mechanism 4 can be movable in the left and right directions. In this way, even if the axis of the workpiece 2 and the centering part are not aligned in the left and right directions, the workpiece can be smoothly aligned with the centering part by relatively moving the workpiece or the bearing mounting mechanism and the bearing disassembly mechanism. The adjustment in the left and right directions can refer to the above-mentioned technical solution of the workbench position switching, so that the bearing mounting mechanism 3 and the bearing disassembly mechanism 4 can be movable in the left and right directions in the second installation area 12. Other relevant solutions in other prior art can also be referred to, which will not be elaborated here.

[0073] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to the embodiments, those skilled in the art should understand that modifications or equivalent substitutions to the technical solution of this utility model do not depart from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered by the claims of this utility model.
