Description

Technical Field

[0001] This utility model relates to the field of jack component assembly tools, specifically to a device for disassembling and assembling a jack bearing seat. Background Technology

[0002] The bearing housing is a key component in jack machinery that supports the bearing. It is typically used to support the bearing of the jack and ensure that the bearing rotates smoothly and steadily.

[0003] During the installation of the jack's inner cavity, without specialized tooling, using ordinary pressing tools such as hammering or pressurizing often fails to ensure a smooth entry of the bearing housing and bearing end face. This makes it impossible to guarantee that the bearing housing's axis and the cavity's axis are aligned, leading to uneven stress on the contact surface between the bearing housing and the jack's inner cavity, causing deformation. This not only affects the normal rotation of the bearing but also obstructs the movement of the jack's telescopic rod. During disassembly, the bearing housing cannot be directly separated from the jack's inner wall, and ordinary disassembly tools easily damage the bearing end face. Furthermore, excessive coaxiality between the bearing housing's outer ring and the contact surface makes disassembly difficult, time-consuming, and labor-intensive. Excessive deviation will affect the use of both the bearing housing and the bearing. Utility Model Content

[0005] This application provides a device for disassembling and reassembling a jack bearing housing, comprising:

[0006] The docking assembly includes a connecting plate for mounting on the top of the cylinder of the jack to be assembled and a combined bushing disposed on the side of the connecting plate away from the jack to be assembled.

[0007] The motion assembly includes a rotating screw that passes through the combined bushing and connecting plate to enter the cylinder of the jack to be assembled and is axially displaceable. The end of the rotating screw that enters the cylinder of the jack to be assembled is detachably provided with a connecting seat for pre-setting on the bearing seat to be installed or removed. The connecting seat includes an installation connecting seat for abutting against the top end face of the bearing seat to be installed or removed and a disassembly connecting seat for engaging with the bottom end face of the bearing seat to be installed or removed.

[0008] A pushing assembly includes a set of fixing nuts and a swivel nut fitted to the outer periphery of a rotating screw. The fixing nuts are detachably disposed within the combined bushing and are installed in conjunction with the mounting connector. The swivel nut is located on the rod of the rotating screw extending out of the combined bushing and is installed in conjunction with the detachable connector.

[0009] In one embodiment, the connecting plate includes an outer plate and an inner plate protruding away from the jack to be assembled, wherein the inner diameter of the inner plate is equal to the inner diameter of the cylinder of the jack to be assembled, and the rotating screw passes through the center point of the inner plate.

[0010] In one embodiment, the outer disk is provided with a plurality of connecting holes, which are equidistantly arranged along the circumference of the outer disk. Each connecting hole is provided with a connecting bolt that passes through the connecting hole to pass through the top flange of the cylinder of the jack to be assembled.

[0011] In one embodiment, one end of the rotating screw is provided with a protruding end, and the mounting connector and the disassembly connector are both provided with an embedded end that mates with the protruding end on the side facing the rotating screw. The embedded end includes two connecting ears that are radially spaced along the jack to be assembled.

[0012] In one embodiment, a connecting through hole is provided laterally at the relative position of the connecting ear and the protruding end, and a fixing pin is provided in the connecting through hole.

[0013] In one embodiment, the mounting connector includes a base plate connected to the rotating screw and used to abut against the internal planar bearing of the bearing housing to be installed or removed, and a first protruding plate located at the bottom of the base plate for accessing the through hole in the middle of the bearing housing to be installed or removed. The disassembly connector includes a second protruding plate connected to the rotating screw and used to extend into the bottom surface of the through hole in the middle of the bearing housing to be installed or removed, and a second base plate located at the bottom of the second protruding plate for engaging with the outer periphery of the bottom surface of the through hole in the middle of the bearing housing to be installed or removed.

[0014] In one embodiment, the combined bushing includes a first bushing and a second bushing located at the end of the first bushing away from the jack to be assembled, wherein the first bushing has an axially formed hexagonal through hole for securing the nut.

[0015] In one embodiment, the outer wall of the first bushing is provided with a fastening bolt for radial displacement along the jack to be assembled, one end of the fastening bolt penetrating the outer wall of the first bushing to abut against the fixing nut.

[0016] In one embodiment, the second bushing is provided with a rotating bearing, the rotating bearing including a first rotating disk facing the first bushing and a second rotating disk away from the first bushing, the actuating nut including a nut end and a boss end facing the rotating bearing, and the end of the combined bushing away from the connecting disk is provided with an inner recess for exposing the end face of the second rotating disk so that the boss end of the actuating nut is embedded and abuts against the rotating bearing.

The end of the rotating screw extending out of the combined bushing is provided with a connecting protrusion for connecting with an external rotating mechanism.

[0018] The beneficial effects of the technical solutions provided in this application include:

[0019] By controlling the linear pressing and pushing of the bearing housing through the rotation of the screw drive, the skew deformation caused by hammering is avoided, ensuring that the bearing housing to be installed fits snugly against the inner wall of the jack. During disassembly, rotating the bearing drives the rotating screw to retract, making it easier to pull out the bearing housing. During installation, the fixing nut locks the screw, pressing it in smoothly and reducing installation deformation and disassembly damage, ensuring long-term stable use of the bearing housing and jack. This solves the problems of easy skew, laboriousness, and damage to parts caused by traditional disassembly and assembly methods, making the installation and disassembly of jack bearing housings more efficient and reliable.

[0031] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present application.

[0032] This application provides a device for disassembling and assembling a jack bearing seat, which can solve the technical problem that when installing and disassembling the bearing seat of a jack, simple methods such as hammering and pressing with a press are insufficient to ensure the axial displacement of the bearing seat, resulting in uneven force on the contact surface between the bearing seat and the inner wall cavity of the jack, causing deformation.

[0033] The disassembly and assembly device for the jack bearing housing in this application includes a docking assembly, a motion assembly, and a pushing assembly. The docking assembly is used to dock with the jack to be assembled and the bearing housing to be installed or disassembled, respectively. The motion assembly is used to enter the jack to be assembled and, under the limitation of the docking assembly, drive the bearing housing to be installed or disassembled to move axially. The pushing assembly is fitted around the outer periphery of the motion assembly and provides displacement power to the motion assembly.

[0034] Specifically, Figure 1 A schematic diagram of the connection state of the connecting seat 3 in a disassembly and assembly device for a jack bearing housing provided in this application embodiment. Figure 2 This application provides a schematic diagram of the connection state of the disassembly connecting seat 4 in a jack bearing housing disassembly and assembly device, as shown in the embodiment of this application. Figure 1 , Figure 2 As shown, the docking assembly includes a connecting plate 1 for mounting on the top of the cylinder of the jack to be assembled and a combined bushing 5 disposed on the side of the connecting plate 1 away from the jack to be assembled. The connecting plate 1 is a disc-shaped structure, which is used to mount at the top opening of the cylinder of the jack to be assembled so that the connecting plate 1 is perpendicular to the axis of the jack and serves as the axial positioning base for the moving assembly. The combined bushing 5 is welded to the center of the connecting plate 1 and forms an integral part, with a certain chamfer at the mating surface to ensure that the two are welded tightly. The axis of the combined bushing 5 is perpendicular to the axis of the connecting plate 1.

[0035] Furthermore, the moving component includes a rotating screw 2 that is axially displaceable, with one end penetrating through the combined bushing 5 and the connecting plate 1 to enter the cylinder of the jack to be assembled. One end of the rotating screw 2 entering the cylinder of the jack to be assembled is detachably provided with a connecting seat for pre-setting on the bearing seat to be installed or removed. The combined bushing 5 is axially penetrating so that one end of the rotating screw 2 near the connecting plate 1 passes through and longitudinally penetrates the center point of the connecting plate 1. One end of the rotating screw 2 enters the cylinder of the jack to be assembled and connects to the connecting seat, while the other end extends out of the combined bushing 5. The connecting seat includes an installation connecting seat 3, which is selectively provided to abut against the top end face of the bearing seat to be installed or removed, and a disassembly connecting seat 4, which is used to engage with the bottom end face of the bearing seat to be installed or removed.

[0036] The disassembly and assembly device in this application is suitable for both disassembly and assembly conditions. The mounting connector 3 is suitable for the assembly condition, and the disassembly connector 4 is suitable for the disassembly condition. When the assembly is completed, the mounting connector 3 abuts against the top end face of the bearing housing to be installed or disassembled, so as to push the bearing housing to be installed or disassembled into the jack to be assembled. The disassembly connector 4 passes through the middle through hole of the bearing housing to be installed or disassembled and engages with the bottom of the bearing housing to be installed or disassembled, so as to pull out the bearing housing to be installed or disassembled.

[0037] Furthermore, the actuating component includes a set of fixing nuts 7 and actuating nuts 10 that fit around the outer periphery of the rotating screw 2. The fixing nuts 7 are detachably disposed within the combined bushing 5 and are installed in conjunction with the mounting connector 3. The actuating nuts 10 are located on the rod body of the rotating screw 2 that extends out of the combined bushing 5 and are installed in conjunction with the disassembly connector 4.

[0038] In the combined working condition, the fixing nut 7 is detachably installed inside the combined bushing 5 and engages with the outer periphery of the end of the rotating screw 2 entering the combined bushing 5. By rotating the rotating screw 2, the engagement state of the two causes the rotating screw 2 to start pushing the mounting connecting seat 3 and the bearing seat to be installed and removed into the cylinder of the jack to be assembled. In the disassembly working condition, the disassembly connecting seat 4 first passes through the middle through hole of the bearing seat to be installed and removed to lock the bottom of the bearing seat to be installed and removed. Finally, the fixing nut 7 is removed and the tack nut 10 is installed. By rotating the tack nut 10 with a wrench, the rotating screw 2 starts to drive the disassembly connecting seat 4 and the bearing seat to be installed and removed out of the cylinder of the jack to be assembled.

[0039] In this application, under the engagement condition, an external force is applied to the rotating screw 2 to make it rotate. Through engagement with the fixing nut 7, the circumferential rotation is converted into linear motion, ensuring that the rotating screw 2 drives the bearing housing to be installed or removed to extend axially into the cylinder of the jack to be assembled. Under the disassembly condition, an external force is applied to the turning nut 10 to make it rotate, thereby driving the rotating screw 2 to move axially and pull out the bearing housing to be installed or removed.

[0040] Furthermore, Figure 3 This is a schematic diagram of the connecting disc 1 in a disassembly and assembly device for a jack bearing seat provided in an embodiment of this application, as shown below. Figure 3 As shown, the connecting plate 1 includes an outer plate 101 and an inner plate protruding away from the jack to be assembled. The inner diameter of the inner plate is equal to the inner diameter of the cylinder of the jack to be assembled. The rotating screw 2 passes through the center point of the inner plate. The outer plate 101 is a ring structure with an inner ring diameter larger than the outer diameter of the cylinder, providing sufficient mounting holes. The outer plate 101 serves as the mounting interface with the cylinder of the jack to be assembled and is usually fixed to the end face of the cylinder of the jack to be assembled by bolts. In one possible embodiment, a plurality of connecting holes 103 are provided through the outer plate 101. The plurality of connecting holes 103 are equidistantly arranged along the circumference of the outer plate 101. The connecting holes 103 are provided with connecting bolts 104 that pass through the connecting holes 103 to pass through the top flange of the cylinder of the jack to be assembled. The inner plate is located at the inner ring of the outer plate 101. The two are welded together to form a whole. The protruding arrangement of the inner plate can reserve the connection space between the rotating screw 2 and the connecting seat and can extend the effective stroke distance of the rotating screw 2.

[0041] Furthermore, Figure 4 This is a schematic diagram of the rotating screw 2 in a disassembly and assembly device for a jack bearing seat provided in an embodiment of this application, as shown below. Figure 4As shown, one end of the rotating screw 2 has a protruding end 201. The mounting connector 3 and the disassembly connector 4 both have an embedded end that mates with the protruding end 201 on the side facing the rotating screw 2. The embedded end includes two connecting ears 8 that are spaced apart along the radial direction of the jack. The mounting connector 3 and the disassembly connector 4 are detachably connected to the rotating screw 2. The protruding end 201 is located at the end of the rotating screw 2 that is used to enter the cylinder of the jack to be assembled. The two connecting ears 8 on the mounting connector 3 and the disassembly connector 4 are spaced apart to form a space for the protruding end 201 to be embedded. Then, the fixing pin 9 passes through the two connecting ears 8 and the protruding end 201 located between the two connecting ears 8 laterally, realizing the detachable connection between the mounting connector 3 and the disassembly connector 4 and the rotating screw 2.

[0042] Furthermore, Figure 5 This is a schematic diagram of the installation connecting seat 3 in a disassembly and assembly device for a jack bearing housing provided in an embodiment of this application. Figure 5 As shown, the mounting connector 3 includes a base plate 301 connected to the rotating screw 2 and used to support the bearing on the inner end face of the bearing housing to be installed or removed, and a first protruding plate 302 located at the bottom of the base plate 301 for entering the through hole in the middle of the bearing housing to be installed or removed. The bearing housing in commercially available jacks generally has a flat bearing at the top, which is divided into independent upper and lower plates. The upper plate can rotate around the axis relative to the lower plate, and the flat bearing has a through hole in the middle. Therefore, the mounting connector 3 has an inverted T-shaped cross section. The top surface of the base plate 301 is used to set the connecting lug 8 and connect it to the rotating screw 2. The bottom surface of the base plate 301 abuts against the top surface of the upper plate of the flat bearing in the bearing housing to be installed or removed. The first protruding plate 302 enters the through hole in the middle of the bearing housing to be installed or removed. The cross section of the through hole in the middle of the bearing housing to be installed or removed is generally circular. Therefore, the first protruding plate 302 is configured as a cylindrical structure. When the rotating screw 2 rotates, it drives the mounting connector 3 and the upper plate of the flat bearing inside the bearing housing to be installed or removed to rotate synchronously.

[0043] Furthermore, Figure 6 This is a schematic diagram of the disassembly connecting seat 4 in a jack bearing housing disassembly and assembly device provided in an embodiment of this application, as shown in the figure. Figure 6 As shown, the disassembly connector 4 includes a second protruding plate 401 connected to the rotating screw 2 and used to extend into the bottom surface of the through hole in the middle of the bearing housing to be disassembled, and a second bottom plate 402 located at the bottom of the second protruding plate 401 and used to engage with the outer periphery of the bottom surface of the through hole in the middle of the bearing housing to be disassembled.

[0044] In one possible implementation, the second base plate 402 has a racetrack-shaped cross-section, i.e., a rectangular middle section with rounded ends. The width of the rectangular section is smaller than the inner diameter of the through hole in the middle of the bearing housing to be installed or removed, so as to facilitate the vertical passage of the connecting seat 4 through the bearing housing to be installed or removed. It is then adjusted to a lateral position to engage the bottom of the bearing housing to be installed or removed. In the flat position, the top surface of the second base plate 402 abuts against the bottom surface of the bearing housing to be installed or removed, and the second protruding plate 401 extends into the bottom of the through hole in the middle of the bearing housing to be installed or removed. Based on the above description, it can be seen that the connecting seat and the rotating screw 2 are rotatably connected. The connecting seat can rotate around the fixed pin 9 as its rotation axis, so as to facilitate the vertical passage of the connecting seat 4 through the through hole in the middle of the bearing housing to be installed or removed.

[0045] Furthermore, Figure 7 This is a schematic diagram of the combined bushing 5 in a disassembly and assembly device for a jack bearing seat provided in an embodiment of this application, as shown below. Figure 7 As shown, the combined bushing 5 includes a first bushing 501 and a second bushing 502 located at the end of the first bushing 501 away from the jack to be assembled. The first bushing 501 and the second bushing 502 are axially connected along the jack to be assembled. The fixing nut 7 is configured as a hexagon. Therefore, the first bushing 501 has a hexagonal through hole 503 for the fixing nut 7 to be inserted. Under the combined working condition, due to the restriction of the hexagonal through hole 503, the fixing nut 7 is fixed and cannot be moved. While the rotating screw 2 rotates in the fixing nut 7, it pushes the bearing seat to be installed or removed into the cylinder of the jack to be assembled.

[0046] Further, see Figure 7 The outer wall of the first bushing 501 is provided with a fastening bolt 504 for radial displacement along the jack to be assembled. One end of the fastening bolt 504 passes through the outer wall of the first bushing 501 to hold the fixing nut 7. The outer wall of the first bushing 501 has a transversely threaded hole to engage with the fastening bolt 504. By rotating the fastening bolt 504 in different directions, the transverse displacement of the fastening bolt 504 can be achieved. In the engagement condition, the fastening bolt 504 is turned in the forward direction so that one end of the fastening bolt 504 holds the fixing nut 7, fixing the current posture and position of the fixing nut 7 and preventing it from displacing. When it is necessary to remove the fixing nut 7, the fastening bolt 504 is rotated in the reverse direction, and the fastening bolt 504 moves away from the fixing nut 7, so the fixing nut 7 can be removed.

[0047] Furthermore, the second bushing 502 is provided with a rotating bearing 6. The rotating bearing 6 includes a first rotating disk 601 facing the first bushing 501 and a second rotating disk 602 away from the first bushing 501. The swivel nut 10 includes a nut end and a boss end facing the rotating bearing 6. The end of the combined bushing 5 away from the connecting disk 1 is provided with an inner recess 505 for exposing the end face of the second rotating disk 602 so that the boss end of the swivel nut 10 can be inserted and mated with the rotating bearing 6.

[0048] The rotating screw 2 passes through the rotating bearing 6 and is spaced a certain distance from the outer circumference of the rotating bearing 6. The second rotating disk 602 in the rotating bearing 6 is mainly used to rotate together with the tug nut 10 to reduce resistance. After the tug nut 10 is installed, the boss end of the tug nut 10 is connected to the second rotating disk 602 in the rotating bearing 6. Then, an external wrench is used to turn the tug nut 10.

[0049] It should be noted that the rotating bearing 6 is a commonly used planar bearing. A thrust ball bearing or a thrust roller bearing is set between the first rotating disk 601 and the second rotating disk 602. The first rotating disk 601 is fixed, and the second rotating disk 602 rotates around the shaft following the turning nut 10.

[0050] In one possible implementation, the rotating bearing 6 is fixed inside the combined bushing 5 by a snap ring. The snap ring is located at the second rotating disk 602, and the inner diameter of the snap ring is larger than the inner diameter of the second rotating disk 602 so that it protrudes from the surface of the second rotating disk 602, making it easy to move the nut 10 to engage with it.

[0051] Further, see Figure 4 One end of the rotating screw 2 passes through both the combined bushing 5 and the connecting plate 1, while the other end extends beyond the combined bushing 5. The end of the rotating screw 2 extending beyond the combined bushing 5 is provided with a connecting protrusion 202 for connecting to an external rotating mechanism. In the engaged working condition, the rotating screw 2 is rotated directly. Therefore, the connecting protrusion 202 facilitates connection to an external rotating mechanism. For small-tonnage jacks, the rotating screw 2 can also be rotated manually by holding the connecting protrusion 202.

[0052] Figure 8 This is a schematic diagram of the disassembly and assembly device for a jack bearing housing provided in an embodiment of this application, under the assembly condition. Figure 8 As shown, the working mechanism of the jack bearing housing disassembly and assembly device in this application under the assembly condition is as follows: First, the mounting connection seat 3 is pressed against the top of the flat bearing inside the bearing housing to be installed or disassembled.

[0053] The end face is then cleaned, and the fixing nut 7 is installed inside the combined bushing 5. Then, the rotating screw 2 and the mounting connecting seat 3 are connected, and the connecting plate 1 is aligned with the top of the jack cylinder to be assembled. Finally, the rotating screw 2 is rotated. While the rotating screw 2 is rotating inside the fixing nut 7, it pushes the bearing seat to be installed into the jack cylinder to be assembled.

[0054] Figure 9 This is a schematic diagram of the disassembly and assembly process of a jack bearing housing provided in an embodiment of this application, under the disassembly condition. Figure 9As shown, the disassembly and assembly mechanism of the jack bearing housing disassembly and assembly device in this application is as follows: First, remove the fixing nut 7, then put the tampering nut 10 onto the rotating screw 2 and connect it with the rotating bearing 6. Then, adjust the disassembly connecting seat 4 to a vertical position so that it passes through the through hole in the middle of the bearing housing to be disassembled and then lay it flat so that it engages with the bottom surface of the bearing housing to be disassembled. Connect the connecting plate 1 to the top of the jack cylinder to be assembled, and rotate the tampering nut 10 in the opposite direction to drive the rotating screw 2 and the bearing housing to be disassembled to exit the jack cylinder to be assembled.

[0055] It should be noted that the connecting seat and the rotating screw 2 can be connected first and then inserted, or they can be inserted first and then connected, provided that the connection is convenient. This application does not impose any specific restrictions.
