Further, it will be appreciated that the dimensions of the various elements shown in the figures are not drawn to scale, for ease of description, and that the thickness or width of some layers may be exaggerated relative to other layers, for example.
It should be noted that like reference numerals and letters refer to like items in the following figures, and thus, once an item is defined or illustrated in one figure, it will not need to be further discussed or illustrated in detail in the description of the following figure.
As shown in fig. 1-3, the present invention provides a technical solution: the utility model provides a specialized tool of dismantlement engine cylinder liner, includes chest expander 1, and chest expander 1 includes chest expander supporting shoe 101, and chest expander supporting shoe 101 bottom fixedly connected with support column 104, automobile engine 2 has been placed to support column 104 bottom. The automotive engine 2 comprises an engine cylinder 201, and an engine cylinder sleeve 202 is placed inside the engine cylinder 201. The bottom end of the chest expander supporting block 101 is movably connected with a chest expander main tension bolt 102, and the chest expander main tension bolt 102 is communicated with the upper end and the lower end of the chest expander supporting block 101. A coarse pitch screw is able to withstand a greater pulling force than a typical screw and therefore can withstand the weight of the engine cylinder casing 202 during the lifting of the screw. The bottom end of the main tension bolt 102 of the chest expander is provided with a rotating ring, the rotating ring is sleeved with a rotating shaft, both sides of the rotating shaft are fixedly connected with movable connecting rings 105 of the chest expander, and the bottom end of the movable connecting rings 105 of the chest expander is fixedly connected with a bottom plate 106 of the chest expander. In this embodiment, chest expander bottom plate 106 adopts a circular steel plate to cut and forms, and its size is equivalent with engine cylinder 201 internal diameter, and it should be noted that, because the engine cylinder sleeve 202 has been overlapped in the engine cylinder 201, so the internal diameter of engine cylinder sleeve 202 is less than engine cylinder 201, consequently only adopts circular steel plate design can make chest expander bottom plate 106 can't put into engine cylinder sleeve 202 for chest expander 1 can't work. Therefore, the radian of two sides of the round thick steel plate is cut, so that the chest expander bottom plate 106 is a long strip with two circular arc-shaped ends and two flat straight sides consistent with the moving direction of the rotating shaft, when the chest expander bottom plate 106 is placed in, the chest expander bottom plate 106 can be erected firstly, so that the chest expander bottom plate 106 can be placed in the engine cylinder sleeve 202, the movable connection ring 105 of the chest expander is positioned at the gravity center position of the chest expander bottom plate 106, so that the chest expander bottom plate 106 tries to return to the horizontal state after entering the engine cylinder sleeve 202 and is blocked by the inner wall of the engine cylinder sleeve 202, when the chest expander bottom plate 106 continues to go deep and passes through the engine cylinder sleeve 202, the chest expander bottom plate 106 which loses the block is matched with the inner wall of the engine cylinder 201 due to the circular arc of the two ends to restore to the horizontal state, and then the chest expander bottom plate 106 is blocked by the engine cylinder sleeve 202 when being lifted upwards, so that a structure similar to a three-jaw chest expander is formed, the engine cylinder liner 202 is removed.
When using this utility model, the staff at first will rotate chest expander bottom plate 106 to being close vertically, in order to put into engine cylinder 202, until placing support column 104 at engine cylinder 201 upper surface, continue to promote chest expander main tension bolt 102 after that, make chest expander bottom plate 106 sink and exceed engine cylinder 202 bottom, chest expander bottom plate 106 can resume straight this moment, promote chest expander bottom plate 106 once more, make it take up engine cylinder 202 outer wall bottom surface from the below, highly fixed with chest expander main tension bolt 102 through fixation nut 103 after that, the staff holds chest expander supporting shoe 101 after that, mention the instrument is whole, take away from engine cylinder 201 in the same direction as the area with the engine cylinder 202 on chest expander bottom plate 106 top.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the utility model, the scope of which is defined in the appended claims and their equivalents.
