Description

Technical Field

[0001] This utility model relates to the field of workpiece disassembly technology, and more specifically to an assembly-type disassembly tool. Background Technology

[0002] Traditional mechanical disassembly tools require specialized equipment for disassembling parts such as bearings and couplings of different sizes. Most of these tools are fixed in structure and lack flexibility. For example, disassembling a bearing requires separately fixing the outer and inner rings; existing tools struggle to adapt quickly, leading to cumbersome and inefficient operations. Therefore, there is an urgent need for a universal disassembly tool that can adapt to different specifications of equipment parts. Utility Model Content

[0003] 1. Technical problem to be solved by the utility model

[0004] To address the aforementioned shortcomings in the disassembly of bearings, couplings, and other equipment parts in existing technologies, this utility model provides an assembly-type disassembly tool. Through the coordinated operation of a crossbar, a push bar, a grab bar, and a nut, it can adapt to equipment parts such as bearings and couplings of different sizes, simplifying operation and improving disassembly efficiency.

[0005] 2. Technical Solution

[0006] To achieve the above objectives, the technical solution provided by this utility model is as follows:

[0007] An assembly-type disassembly tool is used to separate a tightly fitted central shaft from a workpiece. It includes a crossbar, a push rod, a disassembly nut, two gripping rods, and a clamping nut. The crossbar has a central hole in its middle for the push rod to pass through, and long adjustment holes on both sides for the gripping rods to pass through. The push rod is screwed through the disassembly nut, and its top end presses against the end of the central shaft. The two gripping rods are symmetrically arranged on both sides of the workpiece to be disassembled, with hooks at their bottoms to hook onto the bottom of both sides of the workpiece. The upper part of the gripping rods has external threads. After passing through both ends of the crossbar, the gripping rods are screwed into the clamping nuts, pressing the disassembly nut between the crossbar and the workpiece. During workpiece disassembly, the threaded push rod rotates within the internal threaded hole of the disassembly nut, pushing the central shaft out of the workpiece, thus achieving workpiece disassembly.

[0008] A further technical solution involves symmetrically distributing the long adjustment holes around the central hole, allowing the gripper to adjust laterally within the long adjustment holes, thus enabling the crossbar to adapt to workpieces of different diameters.

[0009] A further technical solution involves a square head on the upper part of the push rod, which facilitates the application of force and rotation with a wrench.

[0010] A further technical solution involves a horizontally perforated hole in the square head, which can be used to assist rotation by inserting an auxiliary rod.

[0011] A further technical solution involves a cone-shaped end of the push rod, used to hold the end of the central shaft.

[0012] A further technical solution involves setting up hanging holes on the upper part of the gripper, allowing for the connection of various components via ropes, making it convenient to carry.

[0013] 3. Beneficial effects

[0014] Compared with the prior art, the technical solution provided by this utility model has the following advantages:

[0015] This utility model's assembly-type disassembly tool can disassemble workpieces such as bearings and couplings of different sizes by adjusting the distance between the two gripping rods; and the push rod achieves a stable linear thrust through the threaded engagement between the push rod and the disassembly nut, avoiding damage to the workpiece caused by traditional impact disassembly; the square head and insertion hole design support manual or lever-assisted operation, improving disassembly efficiency and saving effort and convenience.

[0025] To further understand the content of this utility model, a detailed description of the utility model is provided in conjunction with the accompanying drawings.

[0026] Example 1

[0027] The assembly-type disassembly tool in this embodiment, such as Figure 1 , 2 As shown in Figures 3, 4, and 5, this device is used to separate the tightly fitted central shaft 6 from the workpiece 7. It includes a crossbar 1, a push rod 2, a disassembly nut 3, two gripping rods 4, and a clamping nut 5. The crossbar 1 has a central hole 11 in the middle for the push rod 2 to pass through, and long adjustment holes 12 on both sides for the gripping rods 4 to pass through. The two gripping rods 4 are symmetrically arranged on both sides of the workpiece 7 to be disassembled. The bottom of the gripping rod 4 is provided with a hook platform 42, which hooks onto the bottom of both sides of the workpiece 7. The upper part of the gripping rod 4 is provided with an external thread.

[0028] The assembly-type disassembly tool in this embodiment, such as Figure 1 , 2 As shown in Figures 3, 4, and 5, taking a bearing as an example, after the gripping rod 4 passes through both ends of the crossbar 1, it is screwed onto the gripping rod 4 by the clamping nut 5, pressing the disassembly nut 3 between the crossbar 1 and the bearing; after the push rod 2 is screwed through the disassembly nut 3, its top end is pressed against the shaft end of the central shaft 6; when the bearing is disassembled, the threaded push rod 2 is rotated in the internal thread hole of the disassembly nut 3 to push the central shaft 6 out of the bearing, thus achieving the purpose of bearing disassembly.

[0029] Example 2

[0030] The assembly-type disassembly tool in this embodiment has the same basic structure as in embodiment 1, but the difference or improvement is as follows: Figure 2 As shown, the long adjusting holes 12 are symmetrically distributed around the central hole 11. The gripping rod 4 is laterally adjusted within the long adjusting holes 12, allowing the crossbar 1 to accommodate workpieces 7 of different diameters. Figure 3 As shown, the upper part of the push rod 2 is a square head 21, which facilitates rotation with a wrench. The end of the push rod 2 is a truncated cone 22, used to hold the end of the central shaft 6. Figure 5 As shown, the upper part of the gripper 4 is provided with a hanging hole 41, which can be used to thread a rope through the hole to connect the various parts together for easy carrying.

[0031] The disassembly steps are as follows:

[0032] Install the gripper: Place the disassembly nut 3 on the flat bearing, and hook the hook platform 42 of the two gripper 4 symmetrically hook the bottom of both sides of the workpiece 7; after the top of the gripper 4 passes through the long adjustment hole 12 of the crossbar 1, the gripper 4 is screwed on by the clamping nut 5, and the disassembly nut 3 is clamped between the crossbar 1 and the workpiece 7.

[0033] Assemble the push rod: After the push rod 2 passes through the center hole 11 and is screwed through the disassembly nut 3, the cone 22 is pressed against the shaft end of the central shaft 6;

[0034] Disassembly by force: Rotate the square head 21 with a wrench or insert the lever into the socket 23, rotate the push rod 2 clockwise, and the push rod 2 will push the central shaft 6 away from the bearing.

[0035] The assembly-type disassembly tool in this embodiment achieves "one tool for multiple uses" by adjusting the fixed positions of the two gripping rods 4, which significantly improves disassembly efficiency and versatility.

[0036] The present invention and its embodiments have been described above illustratively. This description is not restrictive, and the figures shown are only one embodiment of the present invention. The actual structure and manufacturing steps are not limited to these. Therefore, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the spirit of the invention, such designs should fall within the protection scope of the present invention.
