Description

Technical Field

[0001] The utility model relates to the technical field of maintenance equipment, in particular to a cylinder liner disassembly tool. Background Art

[0002] The cylinder liner, short for cylinder liner, is inserted into the cylinder barrel of the engine block and, together with the piston and cylinder head, forms the combustion chamber. During long-term engine operation, the cylinder liner is susceptible to wear and tear, necessitating removal for replacement or repair. Currently, cylinder liner removal is typically performed by hammering, a manual operation that applies inconsistent force in both magnitude and direction, making removal difficult. Furthermore, the high hammering force can easily damage other components. Utility Model Content

[0003] In order to overcome the deficiencies of the background technology, the present invention provides a cylinder liner disassembly tool, which solves the problem that disassembling the cylinder liner by hammering is not only difficult but also easily causes damage to other parts.

[0004] The technical solutions adopted in this utility model are as follows:

[0005] Cylinder liner removal tool, including chassis, also includes:

[0006] A top plate, arranged on the upper end of the bottom plate;

[0007] a tapered portion, disposed on the chassis;

[0008] A column is provided between the bottom plate and the top plate, and the column is composed of at least two movable blocks with the same structure;

[0009] A tapered hole is provided on a side of the column close to the chassis and is used to cooperate with the tapered portion, wherein the size of the tapered hole is smaller than the size of the tapered portion;

[0010] A pull rod passes through the top plate and the column and is connected to the tapered portion;

[0011] A top pressure piece is provided on the pull rod and is used to act on the top plate;

[0012] The elastic sleeve is arranged on the outer wall of the column.

[0013] The pull rod is a threaded rod, and the pressing piece is an adjusting nut.

[0014] The other end of the pull rod is provided with a mounting sleeve, and the mounting sleeve is provided with a hanging ring.

[0015] The elastic sleeve is made of rubber.

[0016] The column is composed of four movable blocks with the same structure.

[0017] One end of the elastic sleeve is provided with a limiting surface, and the limiting surface is close to the top plate.

[0018] The limiting surface is provided with a positioning groove for cooperating with the top plate.

[0019] The beneficial effects of the utility model are:

[0020] The top plate is acted on by the top pressure piece, so that the top plate moves downward and drives the column to move downward. Since the size of the tapered hole is smaller than the size of the tapered part, the movable block moves toward the outside, forcing the elastic sleeve to expand, thereby forming an interference fit with the cylinder sleeve. The cylinder sleeve is then pulled out with a pull rod, which makes disassembly easy and will not cause damage to other components. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0028] In the embodiment, Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 As shown, the cylinder liner removal tool includes a chassis 1 and also includes:

[0029] A top plate 2 is provided on the upper end of the bottom plate 1;

[0030] The tapered portion 3 is provided on the chassis 1;

[0031] A column is provided between the bottom plate 1 and the top plate 2, and the column is composed of at least two movable blocks 4 of the same structure;

[0032] The tapered hole 5 is provided on a side of the column close to the chassis 1 and is used to cooperate with the tapered portion 3. The size of the tapered hole 5 is smaller than that of the tapered portion 3.

[0033] The pull rod 6 passes through the top plate 2 and the column and is connected to the tapered portion 3;

[0034] A pressing member 7 is provided on the pull rod 6 and is used to act on the top plate 2;

[0035] The elastic sleeve 8 is provided on the outer wall of the column.

[0036] The top plate 2 is acted on by the top pressure piece 7, so that the top plate 2 moves downward and drives the column to move downward. Since the size of the tapered hole 5 is smaller than the size of the tapered portion 3, the movable block 4 moves outward, forcing the elastic sleeve 8 to expand, thereby forming an interference fit with the cylinder sleeve. The cylinder sleeve is then pulled out with the pull rod 6, which makes disassembly easy and will not cause damage to other components.

[0037] In the embodiment, Figure 1 、 Figure 2 As shown, the pull rod 6 is a threaded rod and the pressing member 7 is an adjusting nut. The top plate 2 is pressed down by rotating the adjusting nut, which is easy to operate.

[0038] In the embodiment, Figure 1 、 Figure 2 As shown, the other end of the pull rod 6 is provided with a mounting sleeve 9, and the mounting sleeve 9 is provided with a lifting ring 10. When manpower cannot pull out the cylinder sleeve, it can be connected to the lifting ring 10 by a pulling device to pull it out.

[0039] In the embodiment, the elastic sleeve 8 is made of rubber, which has good elasticity, wear resistance and low cost.

[0040] In the embodiment, Figure 2 、 Figure 3 As shown, the column is composed of four movable blocks 4 with the same structure. When the four movable blocks 4 are stretched out, the circumferential surface of the cylinder liner can be evenly stressed.

[0041] In the embodiment, Figure 5 As shown, one end of the elastic sleeve 8 is provided with a limiting surface 11, and the limiting surface 11 is close to the top plate 2. The elastic sleeve 8 will not slide down due to gravity, ensuring that the elastic sleeve 8 is in full contact with the column.

[0042] In the embodiment, Figure 5 As shown, the limiting surface 11 is provided with a positioning groove 12 for cooperating with the top plate 2. The top plate 2 is installed in the positioning groove 12. When the top plate 2 is pressed down, each movable block 4 is evenly stressed, thereby ensuring that each movable block 4 exerts a uniform force on the cylinder sleeve.

[0043] Obviously, the above embodiments of the present invention are merely examples for the purpose of illustrating the present invention and are not intended to limit the implementation methods of the present invention. Those skilled in the art will readily appreciate that other variations or modifications based on the above descriptions are possible. It is not necessary and impossible to provide an exhaustive list of implementation methods. However, any obvious variations or modifications arising from the essence of the present invention remain within the scope of protection of the present invention.
