Description

Technical Field

[0001] The utility model relates to a cylinder sleeve auxiliary installation component and belongs to the technical field of cylinder sleeve auxiliary installation. Background Art

[0002] Cylinder liner, also known as cylinder sleeve, is a cylindrical part that is usually placed in the cylinder bore of the engine. Its main function is to reciprocate with the piston in the cylinder body, while also supporting and guiding the piston. The outside of the cylinder liner may be cooled by cooling water to help dissipate heat. Cylinder liners can be made of cast iron, aluminum alloy or other materials, but cast iron cylinder liners are widely used because of their good wear resistance.

[0003] Patent No. CN216381629U discloses an auxiliary tool for installing a cylinder liner of a diesel locomotive, including a cylinder, a fastening screw and a fastener. The front side of the cylinder is provided with an opening, and the left and right ends of the opening on the front side of the cylinder are respectively provided with a left fixing part and a right fixing part. The fastening screw is fixed in the U-shaped groove of the left fixing part by screws, and the right end of the fastening screw is inserted into the U-shaped groove of the right fixing part, and the fastener is spirally connected to the right end of the fastening screw. The utility model has good effects, stable performance, safety and reliability. It changes the traditional cumbersome maintenance method, and the cylinder liner can be installed without disassembling the connecting rod. It greatly improves the working efficiency, saves costs, and reduces the labor intensity of operators.

[0004] However, this type of technology can only install cylinder liners and piston rings that meet the specifications. When the diameters of the cylinder liners and piston rings are large, the opening range of the cylinder is greatly limited. The distance between the cylinder and the fastening screw is smaller than the diameters of the cylinder liners and piston rings, and the cylinder liners and piston rings cannot be installed normally. When it comes to cylinder liners and piston rings of different specifications, it is also necessary to prepare auxiliary installation components of different sizes, which is rather troublesome. At the same time, after the cylinder liner is installed, when removing the cylinder, it is also necessary to rotate the fastening screw to slowly open the cylinder before removing it, which is rather time-consuming.

One end of the fixing rod 14 is movably connected to the mounting plate 15, and a positioning groove 13 corresponding to the positioning mechanism 9 is provided on the upper end of the fixing rod 14. After the bottom end of the clamping block 96 is separated from the positioning groove 13, the two second side rods 6 can be separated from the two clamping blocks 1, and then the two clamping blocks 1 can be quickly moved away from each other, so that they can be removed from the piston ring, which saves time and is more convenient.

[0019] The positioning mechanism 9 includes a mounting block 91, a push block 92, two connecting rods 93, two springs 94, two side blocks 95, a clamping block 96 and an arc surface 97. The mounting block 91 is fixedly connected to the outside of the mounting plate 15. A push block 92 is provided at the bottom of the mounting block 91. A connecting rod 93 is vertically fixed to the upper end of the push block 92. The two connecting rods 93 are movably connected to the mounting block 91. The tops of the two connecting rods 93 are fixedly connected to the side blocks 95. A clamping block 96 is fixedly connected between the two side blocks 95.

The two springs 94 are respectively sleeved on the outer periphery of the two connecting rods 93. When the cylinder sleeve moves to the target position of the piston ring, the push block 92 can be pushed upward. The push block 92 drives the side block 95 to move upward through the connecting rod, thereby pushing the clamping block 96 to move upward and stretching the spring 94 at the same time. When the bottom end of the clamping block 96 is separated from the positioning groove 13, the two second side rods 6 can be separated from the two clamping blocks 1, so that the two clamping blocks 1 can be quickly moved away from each other, so that the piston ring can be removed. , saving time and being more convenient; the upper ends of the two clamping blocks 1 are fixedly connected with the top blocks 3, the two top blocks 3 are both arc-shaped, and the two top blocks 3 are provided with support areas 4 between the opposite sides of the corresponding clamping blocks 1, and the cylinder sleeve is set on the outside of the two top blocks 3 and placed on the two support areas 4, which is convenient for the placement of the cylinder sleeve and ensures stability; the two clamping blocks 1 are fixedly connected with the positioning blocks 12 on one side close to the second side rod 6, and the two positioning blocks 12 are provided with positioning holes 16 on one side, and the two second side rods 6 are fixedly connected with the positioning holes 16 on one side.

[0020] Specifically, when the utility model is used, the two clamping blocks 1 are sleeved on the outer side of the piston ring, and then the rotating block 11 is rotated. The rotating block 11 drives the screw 10 to rotate, and the second side rod 6 threadedly connected with the screw 10 will move toward the other second side rod 6. When the second side rod 6 moves, it drives the clamping block 1 to move synchronously, so that the two clamping blocks 1 are close to each other, thereby compressing the piston ring. Then the cylinder sleeve is sleeved on the outer side of the two top blocks 3 and placed on the two supporting areas 4, which can adapt to cylinder sleeves and piston rings of various sizes and has stronger adaptability. Then, the two clamping blocks 1 are pushed downward, and the cylinder sleeve moves downward accordingly. When the cylinder sleeve moves to the target position of the piston ring, the push block 92 can be pushed upward. The push block 92 drives the side block 95 to move upward through the connecting rod, thereby pushing the clamping block 96 to move upward and stretching the spring 94 at the same time. When the bottom end of the clamping block 96 is separated from the positioning groove 13, the two second side rods 6 can be separated from the two clamping blocks 1, and then the two clamping blocks 1 can be quickly moved away from each other, so that the piston ring can be removed, saving time and being more convenient.
