Description

Technical Field

[0001] The utility model relates to the technical field of engine cylinder liners, in particular to an engine cylinder liners production device. Background Art

[0002] The engine cylinder liner is a cylindrical part placed in the cylinder block hole of the engine body and fixed by the cylinder head. The piston reciprocates in its inner hole and is cooled by cooling water on the outside. The inner surface of the engine cylinder liner is directly affected by high-temperature and high-pressure combustion gas, and is always in high-speed sliding friction with the piston ring and piston skirt. The outer surface is in contact with cooling water, which produces severe thermal stress under large temperature differences.

[0003] Chinese utility model patent CN 218225861 U discloses a grinding and polishing device for automobile cylinder liner production, which relates to the technical field of cylinder liner grinding and polishing, including a working platform, a support rod, a slide rail, a polisher, and a transmission mechanism. The transmission mechanism includes an electric push rod, a first micro motor, a movable rod, a screw rod, and a second micro motor. The utility model sets a transmission mechanism. Each time the cylinder liner needs to be polished, the cylinder liner can be placed outside the support rod, the cylinder liner is fixed by a support assembly, and then the polisher is moved to the vicinity of the outer wall of the cylinder liner, so that the cylinder liner rotates and the polisher can move up and down, thereby cleaning the burrs on the outer wall of the cylinder liner, reducing the steps of manually holding the cylinder liner or the polisher for grinding and polishing, and can limit the cylinder liner of different sizes, reducing the physical consumption of workers and further improving work efficiency.

[0004] During the production process of engine cylinder liners, it is necessary to grind the outer wall of the engine cylinder liners. The above design can quickly fix the engine cylinder liners through a variety of components and mechanisms, and drive the polisher to move up and down to grind and polish the engine cylinder liners. However, there are still certain problems during use. The expansion mechanism of the above design does not have a limiting function, and the contact area between the expansion rod and the inner wall of the engine cylinder liners is small. During grinding and polishing, the position of the engine cylinder liners is easily displaced or even dropped, which reduces the efficiency of engine cylinder liners production.

[0005] Therefore, it is necessary to provide a new engine cylinder liner production equipment to solve the above-mentioned technical problems. Utility Model Content

[0006] In order to solve the above technical problems, the utility model provides an engine cylinder liner production equipment.

[0007] The engine cylinder liner production equipment provided by the utility model includes: a processing table, a grinding machine, and a reciprocating installation shell. Four support rods are symmetrically and fixedly connected to the bottom of the processing table. The grinding machine is arranged above the processing table, and the reciprocating installation shell is arranged above the processing table and is located above the grinding machine; a spreading mechanism is arranged on one side of the grinding machine and is located above the processing table, and is used to firmly fix the engine cylinder liner. The spreading mechanism includes a cross plate, a movable cylinder, a first electric push rod, a spreading rod, a rotating seat, and a rotating rod. Place the engine cylinder liner to be processed on the surface of the spreading mechanism, and the spreading mechanism spreads to firmly fix the engine cylinder liner. The mechanism inside the reciprocating installation shell drives the grinding machine to move up and down to polish the surface of the engine cylinder liner.

A transmission rod is rotatably connected to the circular rod surfaces of the reciprocating disc and the transmission seat. When the second motor on the inner wall of the reciprocating installation shell is started, the output shaft of the second motor controls the reciprocating disc to rotate on the inner wall of the reciprocating installation shell. The circular rod part of the reciprocating disc drives the grinding machine to reciprocate up and down through the cooperation of the transmission rod and the circular rod part of the transmission seat, increasing the grinding range of the grinding machine.

[0012] Preferably, guide plates are symmetrically and fixedly connected to the lower surface of the reciprocating installation shell. Guide blocks are fixedly connected to both side surfaces of the grinding machine, and the guide blocks slide in the rectangular grooves on the inner walls of the guide plates.

During the long-term use of the support rods, when the surface is subjected to extrusion or collision, it will not easily show dents or breakages, extending the service life of the support rods at the bottom of the processing table.
