Problems solved by technology
The defect of this device is that in the process of pulling the device out of the cylinder bore, the body circumferential surface below the annular groove cannot avoid the sealing ring, and the friction between the circumferential surface and the sealing ring can easily distort the sealing ring, resulting in The sealing ring falls off from the inner wall of the cylinder bore, seriously affecting the assembly quality and assembly efficiency

Embodiment Construction
[0022] The technical solutions of the present invention will be described in detail below in conjunction with specific embodiments.
[0023] Such as Figure 1-12 As shown, a cylinder hole sealing ring installation tool includes a cylindrical body, an annular groove 23 for accommodating the sealing ring 16 is provided on the outer ring surface of the cylindrical body, and the annular groove 23 is used as the center of the cylindrical body. The boundary is divided into the upper fixed part 10 and the lower expansion-contraction part; wherein the expansion-contraction part is divided into four fan-shaped sliders 11 by a cross-shaped gap, and each fan-shaped slider 11 is slid along the direction of the bisector of the respective top angles. At the lower end of the fixing part 10; the lower end of the fixing part 10 is provided with four notches 25 corresponding to the four ends of the cross-shaped gap. Pin hole, the pin hole is interspersed with a compression pin 12, the lower en...

The invention belongs to the technical field of automobile engine sealing ring assembly, and particularly relates to a mounting tool of a cylinder hole sealing ring. The mounting tool comprises a cylindrical body. An annular groove used for containing the sealing ring is formed in the outer ring face of the cylindrical body. The cylindrical body is divided into a fixed part on the upper portion and an expansion and contraction part on the lower portion with the annular groove as the boundary. The expansion and contraction part is divided into four sector sliding blocks by a cross-shaped gap. Each of the sector sliding blocks is arranged at the lower end of the fixed part in a sliding manner in the vertex angle bisector direction of the corresponding sector sliding block. The lower half segment of the cylindrical body in the mounting tool is of an expansion and contraction structure, after the sealing ring is mounted in place, the expansion and contraction part contracts to avoid the sealing ring, and the situation that when a device is overall pulled up, the circumference face of the device and the sealing ring generate friction, and consequently the sealing ring falls off is avoided.
Description
technical field [0001] The invention belongs to the technical field of assembly of automobile engine sealing rings, and in particular relates to a cylinder bore sealing ring installation tool. Background technique [0002] During the manufacturing process of the engine cylinder, the cylinder liner and the cylinder block are generally processed separately first, and then the cylinder liner is installed in the cylinder bore of the cylinder block. In order to ensure the tightness of the engine water jacket, a sealing ring needs to be installed between the cylinder liner and the cylinder block. Since the diameter of the cylinder bore is small, and the installation position of the sealing ring is relatively difficult, when installing the sealing ring, it is necessary to use special equipment to send the sealing ring into the cylinder. The invention patent named as a cylinder bore inner seal ring installation device (patent number: ZL201410209324.6) has disclosed the total seal r...
