Abstract
Description
Technical Field
[0001] This utility model relates to the field of grinding equipment technology, and in particular to a cylinder liner end face grinding device. Background Technology
[0002] A cylinder liner is short for engine cylinder liner. It is installed inside the cylinder barrel of the cylinder block and, together with the piston and cylinder head, forms the combustion chamber. Cylinder liners are divided into two main categories: dry cylinder liners and wet cylinder liners. A dry cylinder liner is one whose back side does not contact the coolant, while a wet cylinder liner is one whose back side does contact the coolant. Dry cylinder liners are thinner, have a simpler structure, and are easier to manufacture. Wet cylinder liners, being in direct contact with the coolant, are beneficial for engine cooling and contribute to engine miniaturization and weight reduction.
[0003] When machining cylinder liners, the ends of the cylinder liners need to be ground. Traditional grinding methods require multiple grinding processes on the ends of the cylinder liners. On the one hand, the end face needs to be ground, and on the other hand, the burrs at the edges and corners of the end face need to be ground. This can effectively achieve the grinding of the cylinder liner ends, but it requires setting up multiple equipment and processes to complete the grinding of the end face, which increases the grinding cost.
[0004] In conclusion, the existing technology obviously has inconveniences and defects in practical use, so it is necessary to improve it. Utility Model Content
[0005] To address the aforementioned shortcomings, the purpose of this utility model is to provide a cylinder liner end face grinding device. This device can be configured with a single grinding head structure, ensuring that the cylinder liner end face is ground using a single grinding head when grinding is required. It can also adapt to grinding the end faces of cylinder liners of different sizes, thereby reducing the equipment and process costs of cylinder liner grinding.
[0006] To achieve the above objectives, this utility model provides a cylinder liner end face grinding device, comprising: a main frame; a base for fixing and rotating the cylinder liner, the base being disposed on the main frame; and a grinding assembly disposed on the top of the base for grinding the end face of the cylinder liner, the grinding assembly comprising: a sliding seat slidably connected to the main frame and located at the top of the base, the bottom of the sliding seat being provided with a top surface grinding component; and side grinding components slidably connected to the bottom of the sliding seat and located on both sides of the grinding component, wherein when the top grinding component abuts against the top surface of the cylinder liner, the side grinding components abut against both sides of the cylinder liner.

[0010] In one embodiment, the two ends of the movable grinding head abut against the inner side of the side grinding member, and an abutment spring is provided between the two movable grinding heads. The abutment spring acts to keep both sides of the movable grinding head abutting against the inner sidewall of the side grinding member at all times.
[0011] In one embodiment, the top of the top surface grinding component is provided with a sliding sleeve, the sliding sleeve is slidably connected to the sliding column through a sleeve hole, and the thrust spring is disposed between the sliding sleeve and the sliding column.

[0019] See Figure 1 , Figure 2 and Figure 3This utility model provides a cylinder liner end face grinding device, which includes a main frame; a base for fixing and rotating the cylinder liner 1, the base being disposed on the main frame to ensure that the cylinder liner 1 can be clamped and driven to rotate, thereby further grinding the end of the cylinder liner 1 by a grinding component; the base can be clamped and fixed using a triangular chuck or similar device; and a grinding component disposed on the top of the base for grinding the end face of the cylinder liner 1, the grinding component grinding the burrs on the top surface and edges of the cylinder liner 1, thereby ensuring the grinding effect of the cylinder liner 1. The grinding assembly includes: a sliding seat 2 slidably connected to the main frame and located at the top of the base; the bottom of the sliding seat 2 is provided with a top surface grinding component 4; in use, by instructing the sliding seat 2 to slide up and down, the top surface grinding component 4 can be brought into contact with the top surface of the cylinder liner 1, thereby ensuring the subsequent grinding effect; and side grinding components 3 slidably connected to the bottom of the sliding seat 2 and located on both sides of the grinding component; when the top grinding component is in contact with the top surface of the cylinder liner 1, the side grinding components 3 are in contact with both sides of the cylinder liner 1, and the side grinding components 3 grind the side edges of the top of the cylinder liner 1, thereby effectively ensuring the simultaneous grinding effect of burrs and the top surface.
[0020] In one embodiment, see Figure 3 and Figure 4 The bottom of the sliding seat 2 is provided with a sliding post 21. The top surface grinding part 4 is slidably connected to the sliding post 21. A thrust spring 7 is provided between the top surface grinding part 4 and the sliding post 21. The thrust spring 7 pushes the top surface grinding part 4 to press against the top surface of the cylinder liner 1, ensuring that when the cylinder liner 1 rotates, the top surface grinding part 4 can abut against the top surface of the cylinder liner 1, thereby effectively grinding the top surface of the cylinder liner 1. The bottom of the sliding seat 2 is provided with a slide rail 6. The top of the side grinding part 3 is provided with a sliding part 31 that cooperates with the slide rail 6. The sliding part 31 is slidably engaged inside the slide rail 6, ensuring that the side grinding part 3 can slide to the inner and outer sides of the cylinder liner 1, thereby enabling the side grinding part 3 to grind the end face of the cylinder liner 1, ensuring that the burrs at the end are removed.
[0021] Furthermore, to ensure that the top surface grinding component 4 can completely grind the top surface of the cylinder liner 1, the bottom of the top surface grinding component 4 is provided with a fixed grinding head 43 and a movable grinding head 8 slidably connected to the bottom of the fixed grinding head 43. The working surfaces of the movable grinding head 8 and the fixed grinding head 43 combine to form a grinding surface, ensuring that when grinding cylinder liners 1 of different thicknesses, the movable grinding head 8 and the fixed grinding head 43 can cooperate to achieve full contact and grinding of the top of the cylinder liner 1.
[0022] Specifically, in order to ensure the sliding effect between the movable grinding head 8 and the fixed grinding head 43, both ends of the movable grinding head 8 abut against the inner side of the side grinding component 3, ensuring that when the side grinding head moves left and right, the widths of the movable grinding head 8 and the fixed grinding head 43 move synchronously, thereby adapting to the end grinding of cylinder liners 1 with different thicknesses and sizes. An abutment spring is provided between the two movable grinding heads 8, and the abutment spring acts to keep both sides of the movable grinding head 8 abutting against the inner side wall of the side grinding component 3 at all times, thereby effectively realizing the versatility of the top surface grinding component 4.
[0023] In one embodiment, to achieve the linkage effect between the movement of the top surface grinding component 4 and the side grinding component 3, thereby enabling the grinding of cylinder liners 1 of different sizes, the top surface grinding component 4 is provided with a sliding sleeve. The sliding sleeve is slidably connected to the sliding column 21 through the sleeve hole 41, ensuring that the top surface grinding component 4 can abut against the top surface of the cylinder liner 1, and ensuring that the top surface grinding component 4 can fully grind the top surface of the cylinder liner 1. The thrust spring 7 is disposed between the sliding sleeve and the sliding column 21. The side wall of the sliding sleeve is provided with a mounting seat 42, and the inner side of the side grinding component 3... A rotating seat 32 is provided, and a support rod 5 is provided between the rotating seat 32 and the mounting seat 42. The sliding sleeve slides up and down to push the side grinding part 3 to move left and right, so that the top grinding part 4 can slide up and down and be pulled by the support rod 5 to move the side grinding part 3. Under the action of downward pressure, the top grinding part 4 is pushed by the top force of the cylinder liner 1 to slide, thereby pulling the side grinding part 3 to move inward. This ensures that the top grinding part 4 abuts against the cylinder liner 1, and then the side grinding part 3 abuts against the side of the cylinder liner 1, ensuring that the top of the cylinder liner 1 can be ground.
[0024] Specifically, in combination Figure 5 In order to ensure the smooth connection between the movable grinding head 8 and the fixed grinding head 43, the bottom of the fixed grinding head 43 is provided with a sliding groove 44, and the movable grinding head 8 is slidably connected to the inside of the sliding groove 44, thereby ensuring the sliding effect between the fixed grinding head 43 and the movable grinding head 8, and ensuring the grinding effect of the top surface of different cylinder liners 1.
[0025] Of course, there may be other embodiments of this utility model. Without departing from the spirit and essence of this utility model, those skilled in the art can make various corresponding changes and modifications based on this utility model, but these corresponding changes and modifications should all fall within the protection scope of the appended claims of this utility model.
