Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of mechanical maintenance, and particularly relates to a tool for quickly disassembling parts on a shaft. Background Technique
[0002] In the mechanical industry, the maintenance and repair of equipment are an indispensable part of supporting production. It is to maintain the function or performance of the equipment through maintenance, and to restore the function and performance of the equipment by repairing and replacing parts. In steel production, when replacing parts, since the installation fit between the bearing and the parts on the shaft is interference fit, the principle is that the shaft drives the parts on the shaft to rotate together, but it is relatively difficult to disassemble the parts on the shaft from the shaft.
[0003] The existing ones are difficult to disassemble, and the hydraulic three-jaw chuck cannot clamp the parts to be disassembled; it takes a long time. When using a hammer to apply a force greater than the frictional force to strike the parts, they are withdrawn little by little; the damage is relatively large. Sometimes, when it is difficult to disassemble, a gas cutting method is used to damage the parts and then disassemble them. All the disassembled parts will be replaced. Using a hammer to strike will also damage the parts and even the entire equipment, and affect the service life. Therefore, this application provides a tool for quickly disassembling parts on a shaft to meet the requirements. Content of the Utility Model

[0022] The following will describe in detail a tool for quickly disassembling parts on a shaft provided by the present utility model in conjunction with the accompanying drawings and specific embodiments. At the same time, it should be noted here that in order to make the embodiments more detailed, the following embodiments are the best and preferred embodiments. For those skilled in some well-known technical fields, other alternative methods can also be adopted; moreover, the accompanying drawings are only for more specifically describing the embodiments and are not intended to specifically limit the present utility model.
[0023] It should be noted that in the specification, references to "an embodiment", "embodiments", "exemplary embodiments", "some embodiments", etc. indicate that the described embodiments may include specific features, structures, or characteristics, but not necessarily every embodiment includes such specific features, structures, or characteristics. Additionally, when combining embodiments to describe specific features, structures, or characteristics, implementing such features, structures, or characteristics in combination with other embodiments (whether explicitly described or not) should be within the knowledge of those skilled in the relevant art.
[0024] Generally, terms can be understood, at least in part, from their use in the context. For example, at least in part depending on the context, the term "one or more" as used herein can be used to describe any feature, structure, or characteristic in a singular sense, or can be used to describe a combination of features, structures, or characteristics in a plural sense. Additionally, the term "based on" can be understood as not necessarily intended to convey a set of exclusive factors, but rather, at least in part depending on the context, can allow for the existence of other factors that may not be explicitly described.
[0025] It can be understood that the meanings of "on...", "above...", and "over..." in the present disclosure should be interpreted in the broadest manner, such that "on..." not only means "directly on" something, but also includes the meaning of being "on" something with intervening features or layers therebetween, and "above..." or "over..." not only means "above" or "over" something, but also can include the meaning of being "above" or "over" something with no intervening features or layers therebetween.
[0026] Furthermore, spatial relative terms such as "under...", "below...", "lower", "above...", "upper", etc. are used herein for convenience of description to describe the relationship of one element or feature to another or other elements or features, as shown in the accompanying drawings.

[0027] Such as Figure 1 and Figure 2As shown in the figure, an embodiment of the present utility model provides a tool for quickly disassembling parts on a shaft, including: a channel steel 1, a clamping port 2 is opened on one short side of the channel steel 1, a slide rail 3 is welded to the other short side of the clamping port 2, an external thread 4 is provided on the outer wall of the slide rail 3, a nut 5 is threadedly connected to the outer edge of the external thread 4, and a sliding hammer 6 is slidably sleeved on the outer edge of the external thread 4.
[0028] As Figure 2 and Figure 3 shown, the clamping port 2 is located at a position 8 mm away from the center position and close to the edge on the short side of the channel steel 1, and the maximum diameter of the clamping port 2 is 40 mm. By opening the clamping port 2, the parts to be disassembled from the shaft can be better fixed and clamped, facilitating their disassembly.
[0029] As Figure 1 and Figure 2 shown, the nut 5 is fixed on the slide rail 3, and the nut 5 is located 80 mm away from the other end of the slide rail 3, serving as the upper limit or starting point for the sliding hammer 6. By fixing the nut 5 on the slide rail 3, first, the sliding hammer can be prevented from sliding out of the slide rail 3, and second, the starting point of the sliding hammer 6 moving on the slide rail 3 can be adjusted using the nut 5.
[0030] As Figure 1 and Figure 4 shown, the sliding hammer 6 is an iron part made of cast iron, and the inner diameter of the sliding hammer 6 is 22 cm, the outer diameter is 30 mm, and the maximum outer diameter is 38 mm. By setting the sliding hammer 6, it is convenient for manual grasping and its movement on the slide rail 3.
[0031] As Figure 2 and Figure 4 shown, the diameter of the slide rail 3 is 18 mm and the length is 600 mm. By setting the slide rail 3, the sliding hammer 6 can slide on the slide rail 3 to generate a force.
[0032] As Figure 2 and Figure 4 shown, a partition 7 with a width of 6 mm is fixedly provided at one end of the sliding hammer 6. By setting the partition 7, the contact area at the other end of the sliding hammer 6 is increased.
[0033] For the technical solution provided by the present utility model, during operation, the parts to be disassembled from the shaft are better fixed and clamped through the clamping port 2, facilitating their disassembly. While better clamping the parts, it protects the parts from being damaged during disassembly, and at the same time reduces the damage to the entire device, improves the service life and reusability. The force generated by the movement of the sliding hammer 6 on the slide rail 3 is used to replace the work of a hammer, solving the problem of uneven force received by the hammer when knocking on the parts.
