Description

Technical Field

[0001] The utility model relates to a disassembly and assembly tool, in particular to a multifunctional disassembly and assembly tool, belonging to the technical field of parts disassembly and assembly tools. Background Art

[0002] At present, most of the presses used for equipment maintenance and installation are vertical or horizontal, with large size and mass, so they can only be fixedly installed in workshops for use. Some parts of equipment need to be assembled together by pressing. During on-site installation, manual installation is inconvenient and there are no suitable tools, so they can only be transported to the workshop for installation, which makes the installation time-consuming, labor-intensive and costly.

[0003] In addition, the pullers commonly used on the market are of fixed size and are suitable for a small range of workpiece sizes. For parts with different outer diameters, the maintainer needs to be equipped with pullers of different specifications. For parts with different axial sizes, they also need to be equipped with puller claws of different lengths to meet the needs. Moreover, the puller can only disassemble the parts on the shaft system and does not have the function of installing the parts. Secondly, the clamping claws and the pull rod of the existing puller are integrated, and are only suitable for use in occasions with large spaces. For disassembly occasions with small gaps, the clamping claws are too large to extend into the gaps, and thus cannot clamp the parts, resulting in difficulty in disassembly.

[0004] In summary, how to propose a multifunctional disassembly and assembly tool to address the above technical issues has become an urgent problem to be solved by technicians in this field. Utility Model Content

[0032] The hydraulic cylinder 1, the cylinder seat 3 and the supporting base 4 are coaxially arranged in sequence, and the hydraulic cylinder 1 is connected to the cylinder seat 3 through threads.

[0033] A plurality of positioning holes are evenly spaced along the length direction of the pull rod 2, and a replaceable claw 6 is inserted at one end of the pull rod 2, and the claw head of the replaceable claw 6 points to the axis of the hydraulic cylinder 1. A slider 9 is sleeved on the pull rod 2, and the pull rod 2 is positioned on the slider 9 by a pin 8.

[0034] A plurality of first tie rod slide rails 3-1 are fixedly connected at equal angles to the outer circumference of the cylinder seat 3, and a plurality of second tie rod slide rails 4-1 are fixedly connected at equal angles to the outer circumference of the support base 4; the first tie rod slide rail 3-1 and the second tie rod slide rail 4-1 are both perpendicular to the axis of the hydraulic cylinder 1; a stepped through hole is opened at the center of the support base 4, and a stepped cover plate 7 is coaxially embedded in the stepped through hole.

[0035] A plurality of positioning holes are formed in the length direction of the second pull rod slide rail 4 - 1 , and the second pull rod slide rail 4 - 1 is connected to the pull rod 2 via a pin 8 .

[0036] The first pull rod slide rail 3 - 1 is slidably connected to the slider 9 so that the slider 9 can slide along the length direction of the first pull rod slide rail 3 - 1 .

[0037] In this embodiment, the assembly of the hydraulic cylinder 1, the cylinder seat 3, the replaceable claws 6 and a plurality of pull rods 2 can be used as a puller.

[0038] In this embodiment, the assembly of the hydraulic cylinder 1, the cylinder seat 3, the support base 4 and the plurality of tie rods 2 can be used as a press.

[0039] Specific implementation method 2: Combination Figures 1 to 8 To illustrate this embodiment, in this embodiment, the first pull rod slide rail 3-1 is a gantry-like structure, and the first pull rod slide rail 3-1 includes a connecting plate 3-2 and two long strips 3-3, and the two ends of the long strips 3-3 are fixedly connected to the connecting plate 3-2 and the outer circumferential surface of the cylinder seat 3 respectively.

[0040] Furthermore, the first pull rod slide rail 3 - 1 also includes an adjusting bolt 5 , which is mounted on the connecting plate 3 - 2 , and an annular groove is formed on the circumferential surface of the adjusting bolt 5 .

[0041] Two baffles 9-1 are installed on the slider 9. U-shaped holes are opened on the two baffles 9-1. The two U-shaped holes are connected to form a circular hole. The inner diameter of the circular hole is equal to the outer diameter of the annular groove. The adjusting bolt 5 is rotatably connected to the baffle 9-1.

[0042] The adjusting bolt 5 is threadedly connected to the connecting plate 3 - 2 . When the adjusting bolt 5 is screwed, the adjusting bolt 5 drives the sliding block 9 to move along the length direction of the first pull rod slide rail 3 - 1 through the baffle plate 9 - 1 .

[0043] In this embodiment, a groove is provided on the side surface of the slider 9, the width of the groove is the same as the width of the long plate 3-3, the depth of the groove is the same as the thickness of the long plate 3-3, and the groove and the long plate 3-3 are slidably matched. With such an arrangement, when the adjusting bolt 5 is screwed, the slider 9 can slide along the length direction of the first pull rod slide rail 3-1, thereby ensuring that the claw head of the replaceable claw 6 is firmly against the disassembled part on the shaft, thereby preventing the replaceable claw 6 from falling out during operation and causing injury.

[0047] Specific implementation method four: Combination Figure 1 To explain this embodiment, the number of the pull rod 2, the first pull rod slide rail 3-1 and the second pull rod slide rail 4-1 in this embodiment are 2 to 4. Other components and connection relationships are the same as those in the first, second or third embodiment.

[0048] How it works

[0049] Combination Figures 1 to 8 Explain the working principle of the utility model:

[0050] The utility model is used in conjunction with a hydraulic pump station, such as Figure 6 As shown, after the hydraulic cylinder 1, the cylinder seat 3, the support base 4 and a plurality of tie rods 2 are assembled, the utility model can be used as a press, the support base 4 provides support for the shaft and the parts to be installed, and the hydraulic cylinder 1 is used for pressurization.

[0051] When the size of the parts to be installed is small, the step cover plate 7 is installed in the step through hole of the support base 4, and the parts are placed on the step cover plate 7 for press-fitting; when the size of the parts to be installed is large, such as installing a flywheel on a shaft, the step cover plate 7 is not installed in the step through hole of the support base 4, and the shaft body passes through the step through hole, and the axial positioning is achieved by the shaft shoulder on the shaft and the step through hole. This arrangement is convenient for the installation of parts and provides convenience for the on-site installation of shaft system parts.

[0052] like Figure 7 As shown, after the hydraulic cylinder 1, the cylinder seat 3, the replaceable claw 6 and several pull rods 2 are assembled, the utility model can be used as a puller. The adjusting bolt 5 is screwed to adjust the position of the slider 9 on the first pull rod slide rail 3-1 so that the replaceable claw 6 is against the part on the shaft that needs to be removed. The hydraulic cylinder 1 applies pressure to the shaft, and the part can be removed from the shaft. Such an arrangement facilitates the disassembly of the shaft system parts on site.

[0053] The present invention has been disclosed as above in the form of a preferred embodiment, but it is not intended to limit the present invention. Any simple modification, equivalent changes and modifications made to the above implementation cases by any professional and technical personnel who do not deviate from the content of the technical solution of the present invention and based on the technical essence of the present invention are still within the scope of the technical solution of the present invention.
