Description

Technical Field

[0001] This application relates to the field of disassembly tooling technology, and in particular to disassembly devices. Background Technology

[0002] Mounted spherical roller bearings are bearing units that integrate the rolling bearing and bearing housing into one unit. They are suitable for applications with simple equipment and component requirements, such as tobacco machinery, transportation systems, and construction machinery. In cigarette production lines, thousands of these bearings are used, widely distributed in various equipment such as tobacco processing lines, tobacco expansion lines, and tobacco stem lines. Both regular maintenance and irregular repairs of the equipment involve the disassembly and installation of the bearing housing. Because the equipment often operates in harsh environments such as humidity and low temperatures, the outer ring of the bearing housing, the cage, and the bearing itself are prone to corrosion, leading to problems such as shaft misalignment and abnormal equipment noise, thus necessitating the replacement of the damaged bearing housing.

[0003] When disassembling the bearing housing, on the one hand, it is necessary to first loosen the locking screws on the bearing eccentric sleeve and remove the eccentric sleeve. However, some equipment is difficult to install due to narrow installation locations, obstructed by frames, walls, etc., making it impossible to use tools such as jacks and hydraulic pullers, thus hindering maintenance. On the other hand, the bearing housing and drive shaft are interference fit, and after corrosion, the fit becomes even tighter, making it difficult to remove the bearing along with the bearing housing from the shaft as a whole. After removing the bearing housing bolts, it is difficult to pry open the gap between the bearing housing and the machine body with a pry bar. If the method of disassembling the outer ring, destroying the cage, removing the balls, and finally directly destroying the bearing housing with a cutting machine is not only difficult and time-consuming, but also poses safety hazards. Utility Model Content

[0004] Therefore, it is necessary to provide a disassembly device that can facilitate the disassembly of the bearing housing without damaging it, thereby improving disassembly efficiency.

[0005] This application provides a disassembly device for a spherical bearing with a mounting plate. The disassembly device includes:

[0006] The base is provided with a connecting hole and at least three mounting holes opened along a first direction, the at least three mounting holes being arranged around the connecting hole;

[0007] The driving component includes a main body and an abutment portion that is telescopically connected to the main body in a first direction. The main body is disposed through a connecting hole in the first direction and is connected to a base by means of the connecting hole. The abutment portion is used to abut against the end face of the drive shaft connected to the outer spherical bearing.

[0008] At least three support members, each corresponding to a mounting hole; the support members are connected to the base via the corresponding mounting holes; and

[0009] The auxiliary straightening component has a clearance hole and at least three straightening holes opened along the first direction. The clearance hole is used to avoid the drive shaft. The at least three straightening holes are arranged in a one-to-one correspondence with at least three support members. The support members are connected to the auxiliary straightening component by means of the corresponding straightening holes. One end of the support member along the first direction extends through the straightening hole and is used to engage between the inner ring and the outer ring of the outer spherical bearing.

[0010] In one embodiment, the auxiliary correction component includes at least three correction parts, which are arranged around an axis and connected end to end, with the axis being parallel to each other in a first direction.

[0011] Two adjacent orthodontic units are detachably connected and connected to each other, with an orthodontic hole defined on one side, and at least three orthodontic units have clearance holes defined on their inner sides.

[0012] In one embodiment, the auxiliary corrective element further includes a fastener, and two adjacent corrective parts are detachably connected by means of the fastener.

[0013] In one embodiment, the support member includes a first segment, a second segment, and a third segment arranged sequentially along a first direction;

[0014] The first section is connected to the base, the second section is connected to the auxiliary straightening component, and the third section is located at one end opposite to the second section and is used to snap between the inner and outer rings of the outer spherical bearing with a mounting plate.

[0015] The first segment is configured as a threaded segment, and the disassembly device also includes at least three fixing components that correspond one-to-one with at least three support members. The first segment is detachably connected to the base by means of the corresponding fixing components; and / or

[0016] The cross-section of the second segment and the cross-section of the correction hole are both constructed with the same shape and are both polygons. The cross-section of the second segment and the cross-section of the correction hole are both perpendicular to the first direction.

[0017] In one embodiment, when the first segment is configured as a threaded segment, the dimension of the first segment along the first direction is larger than the dimension of the mounting hole along the first direction; and / or

[0018] The cross-section of the second section and the cross-section of the correction hole are both constructed as rectangles.

[0019] In one embodiment, the mounting hole extends radially through the outer peripheral surface of the base.

[0020] In one embodiment, the mounting hole extends radially from the base to a length greater than the radial dimension of the support.

[0021] In one embodiment, at least three mounting holes are evenly distributed around the center line of the connecting hole, and the extension direction of the center line of the connecting hole is parallel to the first direction.

[0022] In one embodiment, the abutment portion has a tip for abutting the end face of the drive shaft, the tip being configured to abut the center of the end face of the drive shaft.

[0023] In one embodiment, the connecting hole is constructed as a threaded hole, and the main body is provided with an external thread that mates with the connecting hole. The main body is threadedly connected to the base via the connecting hole; and / or

[0024] The drive mechanism of the drive component is configured as hydraulic drive.

[0025] The disassembly device described above includes at least a base, a drive component, at least three support components, and auxiliary straightening components. The base has connecting holes and mounting holes surrounding them. The connecting holes connect to the main body of the drive component, and the mounting holes mount the support components, thus ensuring that the at least three support components are arranged around the drive component. When the drive component's abutting portion abuts against the end face of the drive shaft, and one end of each of the at least three support components is engaged between the inner and outer rings of the spherical roller bearing, the abutting portion of the drive component directly acts on the end face of the drive shaft, providing axial thrust. The at least three support components form a more stable geometric support, limiting the radial wobble of the inner and outer rings of the spherical roller bearing during disassembly. This facilitates the force of the drive component acting on the drive shaft along its axial direction, thereby reducing the risk of jamming or component scratches due to misalignment. Furthermore, by incorporating auxiliary straightening components, the at least three support members are inserted into these components. This not only forces the ends of the at least three support members that are engaged between the inner and outer rings of the spherical roller bearing to be in the desired position, reducing the risk of uneven force distribution caused by support member misalignment, but also connects the at least three support members into a single unit, improving the overall structural rigidity and reducing the risk of force loss or component jamming caused by support member deformation. Thus, through the cooperation of the base, drive component, support components, and auxiliary straightening components, a structure is formed that allows for easy disassembly of the bearing housing without damaging it, thereby improving disassembly efficiency. In addition, this structural arrangement allows for more efficient use of the circumferential space of the drive shaft, resulting in a more compact overall structure for the disassembly device, enabling its use even in space-constrained situations.

[0054] Based on some embodiments of this application, please continue to refer to Figures 1 to 3 , Figure 1 This is a three-dimensional structural diagram of the disassembly device 100, the outer spherical bearing 200, and the drive shaft 300 in cooperation, as seen from one perspective in some embodiments of this application. Figure 2 This is a three-dimensional structural diagram of the disassembly device 100, the outer spherical bearing 200, and the drive shaft 300 in cooperation, from another perspective, in some embodiments of this application. Figure 3 This is a side view schematic diagram of the disassembly device 100, the outer spherical bearing 200, and the drive shaft 300 in cooperation, as shown in some embodiments of this application. Embodiments of this application provide a disassembly device 100 for the outer spherical bearing 200. The disassembly device 100 includes a base 110, a drive member 120, at least three support members 130, and an auxiliary straightening member 140.

[0055] Combined with reference Figure 4 , Figure 4 This is a front view of the base 110 in some embodiments of this application. The base 110 is provided with a connection hole 1101 and at least three mounting holes 1102 opened along the first direction F1. The at least three mounting holes 1102 are arranged around the connection hole 1101.

[0056] The base 110 is a foundational component used to support, fix, or bear other components in the disassembly device 100. The main function of the base 110 is to provide a stable mounting platform for other components in the disassembly device 100, thereby ensuring the overall structural stability. Both the connecting hole 1101 and the mounting hole 1102 penetrate the base 110 along the first direction F1. For example, using… Figures 1 to 4 For example, the base 110 can be a plate-like structure, and the base 110 can be roughly a disc-like structure.

[0057] The drive unit 120 includes a main body 121 and an abutment portion 122 that is telescopically connected to the main body 121 along a first direction F1. The main body 121 passes through a connection hole 1101 along the first direction F1 and is connected to the base 110 by means of the connection hole 1101. The abutment portion 122 is used to abut against the end face of the drive shaft 300 connected to the outer spherical bearing 200.

[0058] The drive unit 120 is a retractable drive structure, which mainly achieves the transmission of force along the first direction F1 and the position adjustment of the abutment part 122 through the combination of the main body 121 and the retractable abutment part 122.

[0059] The main body 121 is the basic structure of the drive component 120 and the main carrier of power output. For example, a power source may be integrated inside the main body 121; the power source may be a component such as a hydraulic cylinder or a pneumatic cylinder, etc., without specific limitations. The main body 121 can provide driving force and guide and support the movement of the abutment part 122. The driving force may be hydraulic or pneumatic, etc., without specific limitations.

[0060] The abutment portion 122 is the component that directly contacts the end face of the drive member 120 and the transmission shaft 300. The abutment portion 122 forms a telescopic connection with the main body portion 121 along the first direction F1, that is, the abutment portion 122 can extend or retract relative to the main body portion 121 along the first direction F1. For example, the abutment portion 122 can be a piston rod, a ejector pin, or a push plate, etc., and there is no specific limitation here.

[0061] Each support member 130 corresponds to a mounting hole 1102, and the support member 130 is connected to the base 110 via the corresponding mounting hole 1102. The number of mounting holes 1102 is greater than or equal to the number of support members 130, so that the mounting holes 1102 corresponding to all support members 130 are different. (Refer to reference...) Figure 4 The mounting hole 1102 is a hole pre-set on the base 110. The size and shape of the mounting hole 1102 can match the contour of the support 130, thereby limiting the position of the support 130.

[0062] For example, with Figure 4For example, the illustration shows the case where there are six mounting holes 1102. Figure 1 and Figure 2 For example, the case where there are three support members 130 is illustrated.

[0063] Combined with reference Figure 5 , Figure 5 This is a three-dimensional structural diagram of the auxiliary straightening member 140 in some embodiments of this application. The auxiliary straightening member 140 is provided with a clearance hole 1401 and at least three straightening holes 1402 opened along the first direction F1. The clearance hole 1401 is used to avoid the drive shaft 300. The at least three straightening holes 1402 are provided in a one-to-one correspondence with at least three support members 130. The support member 130 is connected to the auxiliary straightening member 140 by means of the corresponding straightening hole 1402. One end of the support member 130 along the first direction F1 extends through the straightening hole 1402 and is used to engage between the inner ring 210 and the outer ring 220 of the outer spherical bearing 200.

[0064] The auxiliary straightening component 140 is an auxiliary component used to assist in adjusting and correcting the positional deviation of the support component 130, compensating for the assembly error of the support component 130, or improving the stress state. The auxiliary straightening component 140 can assist in the correction and adjustment of the support component 130, thereby ensuring the relative positional accuracy, fit clearance, or stress balance of the support component 130, thus improving the stability and operational reliability of the overall structure.

[0065] For example, in conjunction with reference Figure 6 , Figure 6 This is a three-dimensional structural diagram of a portion of the outer spherical bearing 200 in some embodiments of this application. Wherein, Figure 6 Only the inner ring 210 and outer ring 220 of the spherical roller bearing 200 are shown in the diagram. A ball track 201 is defined between the inner ring 210 and the outer ring 220. After the balls inside the bearing housing are removed, one end of the support member 130 can be inserted between the inner ring 210 and the outer ring 220, and the track 201 enables a snap-fit ​​connection between one end of the support member 130 and the spherical roller bearing 200.

[0066] Therefore, by providing a connection hole 1101 on the base 110 and a mounting hole 1102 around the connection hole 1101, the connection hole 1101 is used to connect the main body 121 of the drive member 120 and the mounting hole 1102 is used to install the support member 130, so that the at least three support members 130 are arranged around the drive member 120. When the abutment portion 122 of the drive member 120 abuts against the end face of the drive shaft 300, and one end of the at least three support members 130 is engaged between the inner ring 210 and the outer ring 220 of the outer spherical bearing 200, the abutment portion 122 of the drive member 120 directly acts on the end face of the drive shaft 300, providing axial thrust. The at least three support members 130 form a more stable geometric support, which can limit the radial wobble of the inner ring 210 and the outer ring 220 of the outer spherical bearing 200 during disassembly, so as to facilitate the force of the drive member 120 acting on the drive shaft 300 along the axial direction of the drive shaft 300, thereby reducing the risk of jamming or component scratches due to misalignment. Furthermore, by providing the auxiliary straightening element 140, the at least three support elements 130 are inserted through the auxiliary straightening element 140. This not only forces the end of the at least three support elements 130 that is engaged between the inner ring 210 and the outer ring 220 of the outer spherical bearing 200 to be in the required position, reducing the risk of uneven force due to the positional displacement of the support elements 130, but also connects the at least three support elements 130 into a whole, improving the rigidity of the overall structure and reducing the risk of force loss or component jamming due to the deformation of the support elements 130. Thus, through the mutual cooperation of the base 110, the drive element 120, the support elements 130, and the auxiliary straightening element 140, a structure is formed that allows for easy disassembly of the bearing housing without damaging it, thereby improving disassembly efficiency. In addition, with such a structural arrangement, the circumferential space of the drive shaft 300 can be utilized more fully, making the overall structure of the disassembly device 100 more compact. The disassembly device 100 can also be used for disassembly when space is limited.

[0067] It is understandable that disassembling the bearing housing by cutting not only requires a large working space, but also involves a high degree of difficulty and time consumption, and poses safety hazards. Compared with cutting the bearing housing, the disassembly device 100 provided in this application embodiment is less restricted by the working space and can reduce the risk of damaging other workpieces, thereby enabling safer and faster completion of bearing housing disassembly and replacement.

[0068] It should also be noted that when the drive shaft 300 is relatively long and the outer spherical bearing 200 is located far from the end of the drive shaft 300, a longer support member 130 can be used. When using a longer support member 130, the positional accuracy of the end of the support member 130 that engages between the inner ring 210 and the outer ring 220 is difficult to control. Since the auxiliary straightening member 140 provided in this embodiment is designed to avoid the drive shaft 300, the auxiliary straightening member 140 can be used to assist in correcting the position of the support member 130 at a point closer to the end of the support member 130 that engages between the inner ring 210 and the outer ring 220, thereby further reducing the risk of uneven force caused by the positional misalignment of the support member 130.

[0069] Based on some embodiments of this application, please continue to refer to Figures 1 to 3 , Figure 5 and in conjunction with reference Figure 7 and Figure 8 , Figure 7 This is an exploded structural diagram of a portion of the auxiliary correction element 140 in some embodiments of this application. Figure 8 This is a front view of the auxiliary correction member 140 in some embodiments of this application. The auxiliary correction member 140 includes at least three correction parts 141, which are arranged end-to-end around an axis, the axis of which is parallel to a first direction F1. Two adjacent correction parts 141 are detachably connected and their sides define a correction hole 1402, and the inner sides of the at least three correction parts 141 define clearance holes 1401.

[0070] For example, the auxiliary corrective element 140 may be generally arranged in a disc shape, and the corrective part 141 may be generally arranged in a fan shape. Figures 1 to 3 , Figure 5 and Figure 8 For example, the illustration shows a scenario where three support members 130 and three corrective parts 141 are provided. A notch is provided on the side where two adjacent corrective parts 141 meet, and the notch of two adjacent corrective parts 141 defines a corrective hole 1402. Figure 7 In the diagram, the position of this part of the correction section 141 corresponding to the correction hole 1402 and the clearance hole 1401 is roughly indicated by dashed lines.

[0071] Thus, by providing a detachable correction part 141 and defining a correction hole 1402 by adjacent correction parts 141, it is convenient to disassemble, install and replace the support 130, thereby further improving the ease of use of the disassembly device 100 and meeting different disassembly needs.

[0072] Based on some embodiments of this application, please continue to refer to Figure 5 , Figure 7 and Figure 8The auxiliary corrective component 140 also includes a fastener 142, which allows two adjacent corrective parts 141 to be detachably connected.

[0073] Thus, by setting fastener 142, it is not only convenient to install and disassemble the straightening part 141, but also beneficial to improve the overall structural strength.

[0074] Of course, in some other embodiments, two adjacent correction parts 141 may also be snapped together, and no specific limitation is made here.

[0075] Based on some embodiments of this application, please continue to refer to Figures 1 to 4 and in conjunction with reference Figure 9 , Figure 9 This is a three-dimensional structural diagram of the support member 130 in some embodiments of this application. The support member 130 includes a first segment 131, a second segment 132, and a third segment 133 arranged sequentially along the first direction F1. The first segment 131 is connected to the base 110, the second segment 132 is connected to the auxiliary straightening member 140, and the end of the third segment 133 opposite to the second segment 132 is used to engage between the inner ring 210 and the outer ring 220 of the outer spherical bearing 200. The first segment 131 is configured as a threaded segment. The disassembly device 100 also includes at least three fixing components 150 corresponding to at least three support members 130. The first segment 131 is detachably connected to the base 110 by means of the corresponding fixing components 150; and / or, the cross-section of the second segment 132 and the cross-section of the straightening hole 1402 are both constructed with the same shape and are both polygonal, and the cross-section of the second segment 132 and the cross-section of the straightening hole 1402 are both perpendicular to the first direction F1.

[0076] For example, the fixing component 150 may include two bolts, which are respectively bolted to the first segment 131 on both sides of the base 110 along the first direction F1. The position of the support 130 relative to the base 110 can be adjusted by adjusting the relative distance between the two bolts.

[0077] For example, a polygon can be a triangle, a quadrilateral, a pentagon, etc., without any specific limitation.

[0078] For example, the end of the third segment 133 that is opposite to the second segment 132 can be constructed as an elliptical flat head shape. After the inner ball bearing of the outer spherical bearing 200 is removed, it can be inserted into the bearing housing. After rotating the support member 130 at a certain angle, it can be locked inside the outer spherical bearing 200, that is, in the aforementioned track 201.

[0079] Thus, by configuring the first segment 131 as a threaded segment, it is not only convenient to connect the support member 130 and the base 110, but also convenient to adjust the position of the support member 130. By constructing the cross-section of the second segment 132 and the cross-section of the straightening hole 1402 as polygons, a surface contact is formed between the second segment 132 and the inner wall of the straightening hole 1402, which is more conducive to restricting the position of the support member 130.

[0080] Based on some embodiments of this application, please continue to refer to Figures 1 to 4 , Figure 9 When the first segment 131 is configured as a threaded segment, the dimension of the first segment 131 along the first direction F1 is greater than the dimension of the mounting hole 1102 along the first direction F1; and / or, the cross-section of the second segment 132 and the cross-section of the straightening hole 1402 are both constructed as rectangles.

[0081] By making the dimension of the first segment 131 along the first direction F1 larger than the dimension of the mounting hole 1102 along the first direction F1, the adjustable range of the position of the support 130 relative to the base 110 can be further increased. The cross-sections of both the second segment 132 and the straightening hole 1402 are constructed as rectangles to facilitate manufacturing.

[0082] Based on some embodiments of this application, please continue to refer to Figure 1 , Figure 2 and Figure 4 The mounting hole 1102 penetrates the outer peripheral surface of the base 110 radially. That is, the outer peripheral surface of the base 110 forms a notch that corresponds one-to-one with the mounting hole 1102.

[0083] In this way, the support member 130 can be installed and removed from the periphery of the base 110, which facilitates the installation and removal of the support member 130.

[0084] Based on some embodiments of this application, please continue to refer to Figure 1 , Figure 2 and Figure 4 The length of the mounting hole 1102 extending radially along the base 110 is greater than the radial dimension of the support 130.

[0085] In this way, the position of the support member 130 relative to the base 110 can be adjusted radially, which not only further improves the accuracy of the spatial position of the support member 130, but also allows for more flexible application in different disassembly scenarios.

[0086] Based on some embodiments of this application, please continue to refer to Figure 1 , Figure 2 and Figure 4 At least three mounting holes 1102 are evenly distributed around the center line of the connecting hole 1101, and the extension direction of the center line of the connecting hole 1101 is parallel to the first direction F1.

[0087] For example, with Figure 4 For example, the illustration shows the case where there are six mounting holes 1102, with one mounting hole 1102 provided on the base 110 every 60°. Of course, when there are three mounting holes 1102, one mounting hole 1102 can be provided on the base 110 every 120°, and no specific limitation is made here.

[0088] Thus, by setting evenly distributed mounting holes 1102, it is beneficial for the support members 130 to be evenly distributed relative to the base 110, thereby making the overall structure more uniformly stressed and more stable, which further facilitates the assembly and disassembly process.

[0089] Based on some embodiments of this application, please continue to refer to Figure 1 and Figure 3 and in conjunction with reference Figure 10 , Figure 10 This is a perspective structural diagram of the drive member 120 in some embodiments of this application. The abutment portion 122 has a tip 1221 for abutting the end face of the drive shaft 300. The tip 1221 is configured to abut the center of the end face of the drive shaft 300.

[0090] By providing the tip 1221, it is beneficial to ensure that the central axis of the drive member 120 and the central axis of the transmission shaft 300 coincide, thereby facilitating the adjustment of the position of the drive member 120 relative to the transmission shaft 300. Furthermore, a recess can be provided at the center of the end face of the transmission shaft 300, allowing the tip 1221 to abut against the center of the end face of the transmission shaft 300 via the recess. Therefore, since the position of the drive member 120 relative to the transmission shaft 300 can be more accurate, the risk of component damage or drive member 120 failure due to center deviation can be reduced.

[0091] Based on some embodiments of this application, please continue to refer to Figures 1 to 4 and Figure 10 The connecting hole 1101 is constructed as a threaded hole, and the main body 121 is provided with an external thread that mates with the connecting hole 1101. The main body 121 is threadedly connected to the base 110 via the connecting hole 1101; and / or, the driving method of the driving member 120 is configured as hydraulic drive.

[0092] For example, with Figure 10 For example, the female connector (not shown in the figure) of the main body 121 can be tightly connected to the male connector on the manual pump via threads, and the bearing housing can be gradually pulled out by continuously pressing the manual pump. Of course, the driving method of the drive component 120 can also be automatic, and no specific restrictions are made here.

[0093] By configuring the connection between the main body 121 and the base 110 as a threaded connection, the position of the main body 121 relative to the base 110 can be adjusted by rotating the main body 121, which facilitates the adjustment of the position of the drive member 120 and allows the abutment portion 122 of the drive member 120 to have a larger stroke range. By configuring the drive member 120 as a hydraulic drive, the drive member 120 not only has a faster response speed and higher control precision, but also makes the overall structure more compact.

[0094] The following description, in conjunction with the situations illustrated in some of the above embodiments, provides an exemplary account of the use of the disassembly device 100 provided in this application, but is not limited thereto.

[0095] Please refer to Figures 1 to 10 First, remove the fixing bolts of the outer spherical roller bearing 200, remove the bearing housing locking ring and bearing end cover, and use pliers or other tools to slightly damage the cage inside the bearing to pry out some of the balls, so as to make room for the insertion of the third section 133 of the support member 130. Then, insert the flat end of the third section 133 of the support member 130 into the ball track 201 of the outer spherical roller bearing 200. Use a wrench to clamp the second section 132 of the support member 130 to rotate the support member 130 by 90°, so that the flat end of the third section 133 of the support member 130 is clamped in the ball track 201 of the outer spherical roller bearing 200. At this time, the force applied by the disassembly device 100 can be applied to the entire outer spherical roller bearing 200. Next, an auxiliary straightening component 140 is installed at the second section 132 of the support member 130, so that the flat end of the third section 133 of the support member 130 can be more accurately engaged into the ball track 201 of the outer spherical bearing 200. Then, the first section 131 of the support member 130 is connected and fixed to the base 110 via the fixing component 150. Next, the main body 121 of the drive member 120 is screwed into the connecting hole 1101 of the base 110, so that the tip 1221 of the abutment part 122 of the drive member 120 abuts against the center of the end face of the drive shaft 300. At this point, the installation of the disassembly device 100 is completed. Finally, the female connector of the main body 121 is tightly connected to the male connector on the manual pump via threads, and the bearing housing can be gradually pulled out by continuously pressing the manual pump.

[0096] During the above-mentioned use, since the first section 131 of the support member 130 is a threaded section, the main body 121 is provided with external threads, the mounting hole 1102 has a certain length and penetrates the base 110, and the auxiliary straightening member 140 is detachable and has a clearance hole 1401, the relative positions between the components of the disassembly device 100 can be more flexible and easier to install, thereby meeting more disassembly and installation scenarios.

[0097] It should be noted that the base 110, support 130 and auxiliary straightening component 140 can be made of heat-treated No. 45 steel, and the fixing component 150 can be a bolt assembly made of heat-treated alloy steel, which helps to improve the overall structural strength of the disassembly device 100.

[0098] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0099] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
