Description

Tool for removing and assembling cylindrical parts

technical field

The utility model relates to a tool for disassembling and assembling a cylindrical part, in particular to a tool for disassembling and assembling a filter.

Background technique

When installing and dismounting some cylindrical parts, due to their special shape, the reliability of tightening and dismounting is relatively low. In order to improve the reliability and consistency of tightening and dismounting, we need a special tool to assemble this Cylindrical parts. The existing tightening tool is a rigid clamp band. If you use this tool to disassemble a cylindrical part with a smooth surface such as a filter, the tool sleeve is easy to slip on the filter, making installation difficult; when tightening, the tool is on the filter Apply tightening force in the middle, if the force is not well grasped, the filter may be flattened, affecting the appearance and performance. In addition, when the operator uses the tool, the position where the filter is stuck is not consistent, and the top of the filter may be stuck, causing damage to the sealing rubber ring on the filter, and this tool cannot determine the tightening torque, so that the tightening The effect is less consistent. There is currently no tool specifically designed to disassemble and assemble cartridge-like components such as filters.

Contents of the invention

The technical problem to be solved by the utility model is to provide a tubular component dismounting tool suitable for disassembling and assembling the tubular component.

In order to solve the above technical problems, the utility model includes a tightening sleeve with a fitting hole at one end, the inner surface of the fitting hole is surrounded by protrusions, and the inner diameter of the fitting hole is adapted to the outer diameter of the cylindrical part to be disassembled; The other end of the tightening sleeve is provided with a tightening device for connecting with a tightening tool.

After the above structure is adopted, the tightening sleeve is fitted on the end of the cylindrical part. Since there are protrusions in the inner ring of the fitting hole, it will neither slip nor cause damage to the cylindrical part during the process of disassembling and assembling the cylindrical part. If it is damaged, and the set hole is set opposite to the tightening device, when disassembling the cylindrical part, connect the fastening tool to the tightening device, so that the force on the cylindrical part can be uniform, and the torque can be easily controlled to enhance the consistency of assembly. The utility model has the advantages of labor saving, convenient assembly and disassembly, and high reliability, and can greatly improve the quality of assembly.

The tightening device is a reinforced cover, the tightening sleeve is provided with an insertion hole at the end of the tightening device, the connecting end of the reinforced cover and the tightening sleeve is provided with a protrusion that can be inserted into the insertion hole, and the reinforced cover is provided with a through protrusion. Outlet wrench hole.

The cross section of the insertion hole and the protruding part is square.

The reinforcing cover is fixed on the tightening sleeve by screws.

The connection between the tightening sleeve and the reinforcement cover protrudes outward to form a boss, and the reinforcement cover is connected to the boss.

The material of the tightening sleeve is nylon.

The material of the reinforced cover is stainless steel.

Description of drawings

Below in conjunction with accompanying drawing and specific embodiment the utility model is described in further detail:

Fig. 1 is the structural representation of the utility model;

FIG. 2 is a top view of FIG. 1 .

Detailed ways

As shown in Figures 1 and 2, the tool for removing and assembling the cylindrical part includes a cylindrical tightening sleeve 2, the upper end of the tightening sleeve 2 is a fitting hole 1, and the inner surface of the fitting hole 1 is surrounded by protrusions 3, and the protrusions 3 It is a long strip, which is arranged along the axial direction of the fitting hole 1, and the inner diameter of the fitting hole 1 is adapted to the outer diameter of the cylindrical part to be disassembled, so that when the tightening sleeve 2 is set on the end of the cylindrical part, the outer diameter of the protrusion 3 The surface is in close contact with the outer surface of the cylindrical part. The lower end of the tightening sleeve 2 is provided with a tightening device for connecting with a tightening tool.

In order to ensure the consistency of the tightening effect, in this embodiment, the tightening sleeve 2 is provided with an insertion hole at the end where the tightening device is installed, that is, at the bottom. The insertion hole is a square hole with a cross section. The tightening device in this embodiment is a reinforced cover 4. The reinforcement cover 4 is fixed on the tightening sleeve 2 by screws 6. The connection end between the reinforcement cover 4 and the tightening sleeve 2, that is, the upper end of the reinforcement cover 4 is provided with a protruding part 5 which can be inserted into the insertion hole. The cross section of the protruding part 5 It is also square, and the reinforcing cover 4 is provided with a wrench hole 7 that runs through the protruding part 5. When the wrench is inserted into the wrench hole 7 to disassemble and assemble the cylindrical part, the protruding part 5 and the insertion hole can well offset the tightening The force between the cover 2 and the reinforcing cover 4 prevents the relative rotation between the tightening cover 2 and the reinforcing cover 4. Due to the limited thickness of the bottom of the tightening sleeve 2, in order to enhance the maximum bearing capacity of the tightening sleeve 2, at the junction of the tightening sleeve 2 and the reinforcement cover 4, that is, the middle part of the bottom surface protrudes outward to form a boss 8, and the reinforcement cover 4 is screwed on the boss 8 superior.

The material of the tightening sleeve 2 in the utility model is nylon, and this kind of tightening sleeve 2 will not damage the cylindrical part during the tightening process. For strengthening the intensity of the present utility model, the material of reinforcing cover 4 uses stainless steel.

For filters with a smooth surface, grooves on the bottom, and protrusions on the bottom, according to the size, number and depth of the grooves, when designing the tightening sleeve 2, select the protrusions 3 that match the filter, Make sure that the tightening sleeve 2 can catch the surface of the filter. In order to reduce the difficulty of processing, there is an undercut groove inside the tightening sleeve 2, which can just accommodate the protruding part of the lower part of the filter.

The above descriptions are only preferred embodiments of the present utility model, and are not intended to limit the present utility model. The foregoing embodiments have described the utility model in detail, and those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the scope of the inventive concept of the present utility model are included in the protection scope of the present utility model.
