Description

Sleeve hand tools

This creation relates to a sleeve hand tool, and in particular to a sleeve hand tool used for disassembling a Pulley disc assembly.

Sleeve is one of the most common parts in hand tools, especially in industrial fields, such as auto repair shops, factories, etc. The use of sleeves can provide users to remove some screws installed in the holes, Nut.

After riding the locomotive for a long time, there will be more or less strange sounds. At this time, the repairer usually cleans and maintains the transmission system. The main process is as follows: remove the front Puli plate and put the Puli plate casing Wash, clean, oil, install, reset and lock, and then remove the rear clutch, housing, avoidance plate, etc.

However, in the above steps, in the operating procedure of using tools to remove the Pulley casing of the former Pulley disk, it is often difficult to dismantle the Pulley disk casing because of the rusting of the Pulley disk casing, which delays the working time limit. Therefore, the creator of this case After thinking about it in detail, and accumulating many years of experience in the sales and research and development of hand tool products, it was finally possible to develop a special tool for motorcycles, so as to improve the lack of conventional use.

This creation provides a sleeve hand tool that fixes the Ply disk sleeve of the front Ply disk, and pushes the Ply disk sleeve out of the rusty and tight crankshaft end by applying thrust.

This creation proposes a sleeve hand tool for disassembling a front Pulley disc assembly. The front Pulley disc assembly includes a Pulley disc, a crankshaft and a Pulley disc sleeve. The sleeve hand tool includes: A sleeve body, one end of the sleeve body is an open opening for socketing the Pulley disc sleeve, the other end of the sleeve body is a half open opening; a compression screw is threaded through the sleeve body On the upper part, the compression screw is used to lock the Pulley sleeve in the sleeve body; and a force screw is arranged at the semi-open opening of the Pulley sleeve to be forced downward Screw in; wherein, when the force application screw is screwed downward under force, the system presses the Pulley disk sleeve of the Pulley disk assembly, so that the Pulley disk sleeve is separated from the crankshaft.

In an embodiment of the present invention, the side wall of the sleeve body described above is provided with a plurality of screw holes adjacent to the open opening, and the screw holes are arranged in a double row correspondingly.

In an embodiment of the present invention, the aforementioned tightening screws are correspondingly inserted through the screw holes in pairs.

In an embodiment of this creation, the aforementioned corresponding arrangement of the tightening screws has an included angle of 100°~150°.

In an embodiment of the present invention, the optimal angle of the tightening screws in the corresponding arrangement described above is 120°.

In an embodiment of the present invention, the semi-open opening of the above-mentioned sleeve body is provided with an internal thread.

In an embodiment of the present creation, after the above-mentioned Pulley sleeve is locked, the axis of the Pulley sleeve is offset from the axial center of the sleeve body.

The sleeve hand tool disclosed in this creation mainly adopts a sleeve structure. The sleeve of the hand tool is sleeved on the sleeve of the Pulley disc, and then the inner wall (side wall) of the sleeve structure is clamped by the tightening screw and the sleeve structure. At this time, the axis of the crankshaft deviates from the axis of the sleeve body to create a slidable space, and the force application screw is screwed in by force by force. Push the crankshaft with force to make the Pulley disc sleeve separate from the end of the crankshaft through the slidable space.

In order to make the above-mentioned features and advantages of this creation more obvious and understandable, the following specific examples are given in conjunction with the accompanying drawings, which are described in detail as follows. The accompanying drawings are mainly simplified schematic diagrams, and the present invention is only illustrated schematically. The basic structure of the creation, therefore, only the elements related to the creation are marked in the drawings, and the elements shown are not drawn in terms of the number, shape, and size ratio of the implementation. The actual size of the actual implementation is A selective design, and its component layout may be more complicated.

The description of the following embodiments refers to the attached drawings to illustrate specific embodiments on which the present creation can be implemented. The direction terms mentioned in this creation, such as "up", "down", "front", "rear", "left", "right", "inner", "outer", "side", etc., are for reference only The direction of the additional schema. Therefore, the direction terms used are used to explain and understand the creation, not to limit the creation. In addition, in the specification, unless expressly described to the contrary, the word "comprising" will be understood as meaning including the described elements, but does not exclude any other elements.

Figure 1 is an exploded schematic diagram of the components of this creation. In FIG. 1, the sleeve hand tool 1 includes: a sleeve body 110, a force application screw 120 and at least one compression screw 130. One end of the sleeve body 110 is an open opening, and the other end is a half open opening. The force screw 120 is arranged at the semi-open opening of the sleeve body 110 to be screwed downward under force, as shown in FIG. 2.

Referring to FIG. 3A, the compression screw 130 is inserted through the sleeve body 110. The side wall of the sleeve body 110 is provided with a plurality of screw holes 112 adjacent to the open opening, and the screw holes 112 are arranged in a double row correspondingly. The tightening screws 130 are correspondingly penetrated through the screw holes 112 in two sets. The included angles of the tightening screws on the two sides are 100°~150°, and the best angle is 120°.

Fig. 4A, Fig. 4B and Fig. 4C are exploded views of the Pulipan assembly before disassembly of the authoring. The front Pulley disc assembly 2 of the locomotive has at least one Pulley disc, a Pulley disc sleeve 210 and a crankshaft 220.

In this embodiment, the sleeve body 110 of the sleeve hand tool 1 is sleeved on the outside of the Puli plate sleeve 210, and then the tightening screw 130 is screwed inward to lock the Puli plate sleeve 210. When the sharp disc sleeve 210 is locked inside the sleeve body 110, the axis of the crankshaft 220 is offset from the axis of the sleeve body 110 (see FIG. 3B).

Finally, screw in the force application screw 120 downwards. At this time, since the Pulley disc sleeve 210 has been locked and fixed in position, the force of the force application screw 120 screwed in downward is just enough to push the crankshaft 220, as shown in Figure 3C. , The crankshaft 220 is separated from the Pulley disc sleeve 210.

To sum up, because of the sleeve structure used in this creation, the sleeve body of the hand tool is sleeved on the Pulley plate sleeve, and then the compression screw and the inner wall (side wall) of the sleeve body are used to clamp the Pulley plate. The sleeve, at this time, the axis of the crankshaft is not in line with the axis of the sleeve body. At this time, the axis of the crankshaft is offset from the axis of the sleeve body, creating a slidable space, and then The force application screw is screwed downward under the force by force, thereby pushing the crankshaft with force, so that the Pulley bushing can be separated from the end of the crankshaft through the slidable space, and the tool can effectively improve the disassembly. The efficiency of Pulipan components.

Although this creation is disclosed in the foregoing embodiment as above, it is not intended to limit this creation. Anyone who is familiar with similar skills, without departing from the spirit and scope of this creation, makes changes and modifications equivalent to replacements, still this creation Within the scope of patent protection.
