[0032] In order to make the technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0033] like Figures 1 to 9 As shown, the utility model provides an eccentric sleeve disassembly and assembly machine, comprising: a driving device and an execution device 3;

[0034] The actuator 3 includes: a cylinder 31, a piston 33, a pull rod 34, a pressure groove 32, and a disassembly assembly; the piston 33 is placed inside the cylinder 31, with its top end upwardly passing through a preset through hole in the top of the cylinder 31 and fixedly connected to the bottom of the pressure groove 32 with an upward opening; the bottom of the pull rod 34 passes through a preset through hole in the pressure groove 32 and is fixed to the top of the cylinder; the eccentric sleeve 102 is sleeved on the pull rod 34 and is located directly above the notch of the pressure groove 32; the disassembly assembly is arranged on the pull rod 34 and abuts against the top of the eccentric sleeve;

[0035] The driving device is connected to the actuator 3 and is used to drive the piston 33 and the cylinder 31 to slide relative to each other.

[0036] In the technical solution of this utility model, reference is made to Figure 3When it is necessary to remove the eccentric sleeve installed on the mechanical equipment, for example, if the eccentric sleeve 102 installed in the mounting hole of the mounting plate 101 is to be removed, the top of the pull rod 34 can be passed through the eccentric sleeve 101, so that the top of the pressure groove 32 abuts against the bottom of the mounting plate 101, and the disassembly component is installed on the pull rod 34, and the disassembly component abuts against the top of the eccentric sleeve 101; start the driving device, drive the piston 33 to slide relative to the cylinder body in the through hole preset at the top of the cylinder body 31, at this time, since the pressure groove 32 fixedly connected to the piston 33 abuts on the mounting plate 101 ( The eccentric sleeve 101 is pressed downwards and the eccentric sleeve 102 is pressed downwards, so that the eccentric sleeve 101 is pressed downwards and the eccentric sleeve 101 is pressed downwards.

[0037] In the technical solution of the present invention, a variety of implementation methods can be used to implement the above-mentioned eccentric sleeve disassembly and assembly machine. The following will take several implementation methods as examples to introduce the technical solution of the present invention in detail.

[0038] For example, preferably, in a specific embodiment of the present invention, Figure 3 As shown, the top of the piston 33 can be a U-shaped structure, and the top of the cylinder body 31 is correspondingly provided with two through holes for the top of the piston to pass through. The axes of the pull rod 34, the pressure groove 32, the piston 33 and the cylinder body 31 are collinear, so as to better ensure the balanced force of the eccentric sleeve during the disassembly and assembly process.

[0039] In the technical solution of the present invention, by setting the top of the piston 33 into a U-shaped structure, more space can be released in the middle to accommodate the pull rod, which facilitates the connection between the pull rod and the cylinder body and can make the overall structure more compact and reduce the size.

[0040] Preferably, as an example, both ends of the pull rod 34 may be provided with external threads, the bottom thereof is threadedly connected to the cylinder body 31, and the top thereof is connected to the disassembly assembly.

[0041] For another example, preferably, in a specific embodiment of the present utility model, Figures 3 to 6 As shown, the disassembly assembly may include: a disassembly seat 37 and a fastener 36;

[0042] The top of the disassembly seat 37 has an outer edge 371 for abutting the eccentric sleeve 102. The diameter of the outer edge 371 is larger than the inner diameter of the eccentric sleeve but does not exceed the outer diameter of the eccentric sleeve. The middle of the disassembly seat 37 has a through hole 373 for the pull rod to pass through.

[0043] Preferably, in a specific embodiment of the present invention, a protrusion 372 can be provided on the outer wall of the lower part of the disassembly seat 37, which is used to be stuck in the notch of the eccentric sleeve 102, thereby limiting the eccentric sleeve and preventing the eccentric sleeve from rotating during the disassembly process.

[0044] Preferably, as an example, the fastener 36 may be a nut.

[0045] In the technical solution of the present invention, when the eccentric sleeve is removed, the disassembly seat 37 is set in the eccentric sleeve 102, and its protrusion is placed in the notch of the eccentric sleeve, and its outer edge 371 abuts against the top of the eccentric sleeve. The pull rod 34 is passed through the through hole 373 of the disassembly seat 37 and fixedly connected with the fastener 36. When the cylinder body 31 drives the pull rod to move downward, the fastener 36 presses the disassembly seat 37 downward, and the outer edge 371 of the disassembly seat pushes the eccentric sleeve downward until the eccentric sleeve leaves the mounting hole 103 and falls into the pressure groove 32. Of course, if it is only used to remove an eccentric sleeve that has failed, it is not necessary to set the protrusion 371 on the disassembly seat 37. It is only necessary to use the outer edge 371 of the disassembly seat to pull out the failed eccentric sleeve.

[0046] In addition, in another embodiment of the present invention, during the disassembly process, assuming that the protrusion 371 is not provided on the outer wall of the disassembly seat 37, the through hole 373 of the disassembly seat can also be directly provided with an internal thread, so that the eccentric sleeve can be removed without the fastener 36. However, if the protrusion 371 is provided on the outer wall of the disassembly seat 37, since the protrusion 371 needs to be provided in the notch of the eccentric sleeve, if the thread is directly provided in the through hole 373 of the disassembly seat, the eccentric sleeve will be driven to rotate together when tightened, which will affect the normal installation and function of the eccentric sleeve. Therefore, it is necessary to set a separate fastener to limit the mounting seat.

[0047] Preferably, as an example, in a preferred embodiment of the present invention, as Figures 4 to 6 As shown, the axis of the lower part of the disassembly seat 37 is eccentrically arranged with the axis of the outer edge 371 of its top, and its eccentricity corresponds to the eccentricity of the eccentric sleeve; the through hole 373 of the disassembly seat is collinear with the axis of its outer edge.

[0048] In the technical solution of the present invention, by eccentrically arranging the lower portion of the disassembly seat and its outer edge, the size of the eccentric sleeve can be better adapted, thereby further improving the stability and accuracy of the eccentric sleeve during the disassembly process.

[0049] In addition, as an example, in a preferred specific embodiment of the present invention, the eccentric sleeve disassembly and assembly machine may further include an installation component 4, and the installation component 4 is used in conjunction with the disassembly component for installing the eccentric sleeve.

[0050] Preferably, as an example, in a specific embodiment of the present invention, as Figure 7 As shown, the mounting assembly 4 may include: a guide block 41 and a limiting washer 42;

[0051] The guide block 41 is sleeved on the pull rod 1 and is located directly below the eccentric sleeve 102. The diameter of the guide block 41 is larger than the inner diameter of the eccentric sleeve and not larger than the outer diameter of the eccentric sleeve.

[0052] The limiting washer 42 is sleeved on the disassembly seat 37 . The diameter of the limiting washer is larger than the outer diameter of the eccentric sleeve and is located between the outer edge 371 of the disassembly seat and the eccentric sleeve.

[0053] In the technical solution of the present invention, when the eccentric sleeve needs to be installed on the corresponding mechanical equipment, for example, when the eccentric sleeve 102 is to be installed in the mounting hole 103 of the mounting plate 101, the upper end of the pull rod 34 is passed through the mounting hole 103, and the top of the pressure groove 32 is abutted against the mounting plate 101. Then, the guide block 41, the eccentric sleeve 102, the limiting washer 42, and the disassembly seat 37 are sleeved on the pull rod 34 in sequence, and the fastener 36 is fixed to the top of the pull rod. At this time, the eccentric sleeve 102 is located between the guide block 41 and the limiting washer 42, and the eccentric sleeve 102 is started. The driving device is activated, and the pull rod moves downward, so that the fastener 36 squeezes the disassembly seat 37 downward, and the outer edge 371 of the disassembly seat 37 squeezes the limiting washer 42 downward, and the limiting washer 42 pushes the eccentric sleeve 102 and the guide block 41 downward to move downward together until the limiting washer 42 abuts against the top surface of the mounting plate 101 and will no longer move downward. At this time, the eccentric sleeve 102 is completely installed in the mounting hole 103. By setting the limiting washer 42, the eccentric sleeve can be accurately installed in the mounting hole to prevent the eccentric sleeve from continuing to move downward after being installed in place.

[0054] During the entire installation process, by setting the guide block, the eccentric sleeve can always be between the guide block 41 and the limiting washer 37, so that the eccentric sleeve can be moved downward as a whole without tilting during the downward movement, resulting in uneven force or damage; and when installing the eccentric sleeve, it is necessary to set a protrusion 372 on the outer wall of the disassembly seat 37, so that during the installation process, the protrusion 372 of the disassembly seat can always be located in the notch of the eccentric sleeve, playing a circumferential limiting role on the eccentric sleeve, preventing the eccentric sleeve from rotating during the downward movement, so that the eccentric sleeve can be installed in place more accurately and quickly according to the actual angle requirements of the eccentric sleeve. Therefore, through the above-mentioned eccentric sleeve disassembly and assembly machine provided by the utility model, there is no need to use the knocking disassembly method, which can protect the eccentric sleeve and mechanical equipment from damage to a great extent, extend the service life, and the installation is accurate, and the installation process is time-saving and labor-saving.

[0055] Preferably, as an example, the pull rod 34 may be provided with a limiting platform corresponding to the position of the guide block, for limiting the guide block 41 to prevent the guide block from falling directly into the pressure groove 32 .

[0056] In addition, as an example, in another embodiment of the present invention, Figure 8 As shown, the disassembly seat 37 can also be used alone to adjust the angle of the eccentric sleeve installed in the mounting hole. The rotating structure 5 is fixed to the top of the disassembly seat 37, and the disassembly seat 37 is placed in the eccentric sleeve so that its protrusion 372 is located in the notch of the eccentric sleeve. The disassembly seat is then driven by the rotating structure to rotate, so that the protrusion 372 of the disassembly seat can push the eccentric sleeve to rotate in the mounting hole, thereby achieving the angle adjustment of the eccentric sleeve.

[0057] Preferably, as an example, the rotating structure may be a bolt, and the bolt may be connected to the disassembly seat through a thread.

[0058] In addition, as an example, in a preferred embodiment of the present invention, Figure 1 As shown, the driving device may include: a hydraulic pump 1 and an oil pipe 2; both ends of the oil pipe 2 are connected to the cylinder body and the hydraulic pump respectively.

[0059] Preferably, as an example, Figure 1 As shown, the oil pipe can be a hose, which can make the operation more flexible. Protection springs 21 are respectively provided at the positions where the two ends of the oil pipe are connected to the cylinder body and the hydraulic pump, so as to prevent the oil pipe connection from being frequently bent and damaged.

[0060] In addition, preferably, in a specific embodiment of the present invention, Figure 2 As shown, the cylinder body is provided with a liquid inlet 311 for connecting the oil pipe.

[0061] In the technical solution of the present invention, an oil bag and a pumping structure are provided in the hydraulic pump 1. By pressing the hydraulic pump 1, the liquid in the oil bag can be pumped into the cylinder 31. The cylinder 31 and the piston 33, the pull rod 34 and the oil pipe 2 are all sealed and connected. A sealed space is formed inside the cylinder. When the liquid enters the cylinder 31 through the oil pipe, the pressure in the cylinder 31 increases, pushing the piston and the cylinder to move relative to each other. Since the pressure groove 32 fixedly connected to the piston 33 is blocked by mechanical equipment and cannot move upward, the cylinder 31 will drive the pull rod 34 to move downward relative to the piston, thereby pulling the pull rod downward, thereby completing the removal or installation of the eccentric sleeve.

[0062] In addition, as an example, in a preferred embodiment of the present invention, Figure 3 and Figure 9 As shown, a return spring 35 may be further provided on the outside of the piston, and a pressure relief valve 12 is provided on the hydraulic pump.

[0063] When the eccentric sleeve is disassembled and assembled, the pull rod is pulled down, and the return spring is in a compressed state. At this time, the pressure relief valve can be pressed to relieve the pressure in the liquid pipeline of the hydraulic pump. At this time, the return spring rebounds, causing the cylinder body 31 to move upward relative to the piston and return to its initial state. It can be seen from this that by providing the pressure relief valve and the return spring, the eccentric sleeve disassembler can automatically return to its initial state after the work is completed, making it easier to use next time.

[0064] To sum up, in the technical solution of the present invention, by rationally designing the eccentric sleeve disassembly and assembly machine and selecting and using the disassembly component and the installation component according to actual needs, the eccentric sleeve can be dismantled, installed and adjusted, which significantly improves the disassembly and assembly efficiency and accuracy of the eccentric sleeve, and to a large extent avoids the damage to the eccentric sleeve and mechanical equipment during the disassembly and assembly by knocking, thereby increasing the service life of the eccentric sleeve.

[0065] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
