Description

Technical Field

[0001] This utility model relates to the field of cylinder head processing technology, specifically to a high-precision surface grinding device for cylinder heads using a surface grinder. Background Technology

[0002] In the field of machining, surface grinding of cylinder heads is a key process to ensure engine performance. In traditional surface grinders, the connection between the cylinder head mounting table and the moving table is generally fixed with bolts. In actual operation, when it is necessary to adjust the position of the cylinder head mounting table on the moving table to adapt to cylinder heads of different sizes or processing requirements, the operator has to use wrenches and other tools to loosen the bolts one by one, and then tighten them again after the position adjustment is completed. This process is not only cumbersome, but also time-consuming. In addition, the bolts are prone to rust and stripping after long-term use, which further increases the difficulty of disassembly and maintenance costs.

[0003] Meanwhile, the traditional fixing method's structural design makes the limit adjustment between the slider and the groove inflexible. When fine-tuning the position of the cylinder head fixing table, the limitations of bolt fixing make it difficult to achieve quick and convenient operation, causing the surface grinder to frequently stop for adjustments during processing, seriously affecting the equipment's working efficiency. Furthermore, the stability of bolt fixing depends on the operator's tightening force; uneven force may cause slight displacement of the cylinder head fixing table during grinding, affecting the quality of cylinder head surface grinding. Therefore, a high-precision surface grinding device for cylinder heads on a surface grinder is proposed to solve the above problems. Utility Model Content

[0004] This utility model proposes a high-precision surface grinding device for cylinder heads of surface grinders, which solves the problem that in the process of high-precision surface grinding of cylinder heads of surface grinders in related technologies, the connection between the cylinder head fixed table and the moving table is generally fixed by bolts, which requires operators to use wrenches and other tools to loosen the bolts one by one, which consumes a lot of time.

[0005] According to one aspect, at least one embodiment of the present invention provides a high-precision surface grinding device for a cylinder head of a surface grinder, comprising:

[0006] A surface grinding machine, wherein a movable table is movably mounted on the surface of the surface grinding machine, a cylinder head fixing table is placed on the surface of the movable table, and a sliding groove is formed on the surface of the movable table;

[0007] A cylinder head mounting platform has a slider fixedly connected to its bottom end, and the slider is slidably connected to the slide groove.

[0008] A limiting post is provided inside the top of the slider. The slider has a limiting post inside and a movable groove is provided inside the limiting post. A limiting clamping post is provided inside the movable groove. The bottom surface of the limiting clamping post is in contact with the inner wall of the groove.

[0009] For example, at least one embodiment of this utility model provides a high-precision surface grinding device for a cylinder head of a surface grinder, which further includes: a stabilizing block fixedly connected inside the limiting clamping column, the stabilizing block being in contact with the inner wall of the moving groove, and the opening size of the stabilizing block being larger than the opening size provided at both ends of the moving groove.

[0010] For example, at least one embodiment of this utility model provides a high-precision surface grinding device for a cylinder head of a surface grinder, which further includes: a spring wound around the outer wall of the limiting clamping column, one end of the spring being fixedly connected to the limiting column, and the other end of the spring being fixedly connected to the stabilizing block.

[0011] For example, at least one embodiment of this utility model provides a high-precision surface grinding device for a cylinder head of a surface grinder, which further includes: a silicone pad ring provided on the outer wall of the spring, wherein the silicone pad ring provided on the outer wall of the spring is in contact with the outer wall of the limiting clamping column.

[0012] For example, at least one embodiment of this utility model provides a high-precision surface grinding device for a cylinder head of a surface grinder, which further includes: a pull ball fixedly connected to the top of the limiting clamping column, the pull ball being spherically shaped and having anti-slip textures on its surface.

[0013] For example, at least one embodiment of this utility model provides a high-precision surface grinding device for a cylinder head of a surface grinder, which further includes: a rubber clamping pad is adhered to the bottom end of the limiting clamping column, the rubber clamping pad is in contact with the inner wall of the slide groove, and the shape of the rubber clamping pad is an array of pyramids.

[0014] For example, at least one embodiment of this utility model provides a high-precision surface grinding device for the cylinder head of a surface grinder, which further includes: a stabilizing bearing sleeved on the outer wall of the limiting column, the stabilizing bearing being in contact with the inner surface of the upper end of the slide groove, and the outer wall of the slider being in contact with the inner wall of the slide groove.

[0015] For example, at least one embodiment of this utility model provides a high-precision surface grinding device for a cylinder head of a surface grinder, which further includes: an array of sliders at the bottom end of the cylinder head fixing table, and the number of sliders and limiting posts being the same and corresponding to each other.

[0016] The working principle and beneficial effects of this utility model are as follows: Traditional grinding devices use bolts to fix the cylinder head fixing platform. Each time the position is adjusted, multiple bolts need to be loosened and tightened with tools, which is a complicated operation process and consumes a lot of time and effort. However, this device is equipped with limiting columns and limiting clamping columns. When it is necessary to adjust the position of the cylinder head fixing platform on the moving platform, the operator only needs to pull the limiting clamping column outward to quickly release the limiting structure between the slide and the slider. No additional tools are needed, and the operation steps are greatly simplified. After the adjustment is completed, the limiting clamping column is released, and the elasticity of the spring makes it quickly return to its original position, and the slider is fixed again. The whole process is smooth and continuous, which greatly improves the efficiency of cylinder head fixing platform position adjustment, reduces the downtime caused by equipment adjustment, and thus improves the working efficiency of the surface grinding machine.

[0017] Furthermore, the rubber clamping pads at the bottom of the limiting clamping column adopt an array of pyramidal designs. Their special shape increases the friction with the inner wall of the slide groove. Even during the grinding of the cylinder head, which generates significant vibration and cutting force, the slider remains firmly fixed in the slide groove, preventing displacement of the cylinder head fixing platform and ensuring the stability and quality of the grinding process. In addition, the silicone gasket ring on the outer wall of the spring effectively reduces the friction and collision between the spring and the inner wall of the moving groove during repeated deformation. This reduces the wear of the spring itself and also reduces the wear on the inner wall of the moving groove, extending the service life of the spring and the moving groove. The stabilizing bearing sleeved on the outer wall of the limiting column reduces the friction between the limiting column and the slide groove, making the slider move more smoothly in the slide groove. This ensures the reliability of the cylinder head fixing platform adjustment and fixation, reduces the possibility of equipment failure, lowers maintenance costs, and enhances the practicality and durability of the entire device.

[0030] Refer to the instruction manual appendix Figure 1-4 A high-precision surface grinding device for cylinder heads of a surface grinder, comprising:

[0031] A surface grinding machine 1 has a movable table 2 on its surface, a cylinder head fixing table 3 placed on the surface of the movable table 2, and a sliding groove 4 formed on the surface of the movable table 2.

[0032] The cylinder head mounting platform 3 has a slider 5 fixedly connected to its bottom end, and the slider 5 is slidably connected to the slide groove 4.

[0033] A limiting post 6 is located at the top of the inside of the slider 5. The slider 5 has a limiting post 6 inside, and a moving groove 7 is provided inside the limiting post 6. A limiting clamping post 8 is provided inside the moving groove 7. The bottom surface of the limiting clamping post 8 is in contact with the inner wall of the groove 4. The surface grinder 1 serves as the basic platform of the entire device. A moving stage 2 is provided on its surface. The moving stage 2 can move on the surface of the surface grinder 1. This movement provides the basis for position adjustment during the grinding of the cylinder head. A cylinder head fixing table 3 is placed on the surface of the moving stage 2 to fix the cylinder head to be ground. A groove 4 is provided on the surface of the moving stage 2. The groove 4 is designed in a straight line. Its length direction is adapted to the movement direction of the moving stage 2 on the surface grinder 1, providing a track for the movement of subsequent components.

[0034] A slider 5 is fixedly connected to the bottom end of the cylinder head mounting platform 3. The slider 5 is in a sliding connection with the slide groove 4. The shape of the slider 5 matches the slide groove 4, and its cross-section is designed to fit the inner wall of the slide groove 4 to ensure that the slider 5 will not easily come out when sliding in the slide groove 4, and can maintain a stable sliding state. Each cylinder head mounting platform 3 is provided with multiple sets of sliders 5 at the bottom end. These sliders 5 are evenly distributed at the bottom end of the cylinder head mounting platform 3 to ensure the balance of the cylinder head mounting platform 3 during the movement process.

[0035] The limiting post 6 is located at the top inside the slider 5. The slider 5 has a space inside to accommodate the limiting post 6. The limiting post 6 has a moving groove 7 inside. The moving groove 7 is a cylindrical channel with a diameter slightly larger than that of the limiting clamping post 8, so that the limiting clamping post 8 can move smoothly inside the moving groove 7. The limiting clamping post 8 is located inside the moving groove 7, and its bottom surface is designed to be flat and fits against the inner wall of the slide groove 4.

[0036] When the position of the cylinder head fixing platform 3 on the moving platform 2 needs to be adjusted, the operator can pull the limiting clamping column 8 outward. Since the limiting clamping column 8 and the moving groove 7 are in clearance fit, the pulling operation is relatively easy. When the limiting clamping column 8 is pulled, its bottom end will disengage from the inner wall of the slide groove 4, thereby releasing the clamping limit inside the slide groove 4, making the limiting structure between the slide groove 4 and the slider 5 ineffective. At this time, relying on the sliding connection effect between the slider 5 and the slide groove 4, the operator can push the cylinder head fixing platform 3 on the upper surface of the moving platform 2 for fine adjustment of its position. Compared with the traditional method of fixing the slider 5 and the slide groove 4 with bolts, this device does not require the use of tools to loosen the bolts. The fixing can be released directly by manual operation, which greatly improves the speed of releasing the fixing. According to actual tests, when adjusting the position of cylinder heads of different specifications, this device can shorten the adjustment time from an average of 5 minutes in the traditional method to less than 30 seconds, which significantly saves operation time and improves the working efficiency of the surface grinder 1.

[0037] A stabilizing block 10 is fixedly connected inside the limiting clamping column 8. The stabilizing block 10 is frustoconical in shape, with its large-diameter end fitting against the inner wall of the moving groove 7 and its small-diameter end facing inward into the moving groove 7. The opening of the stabilizing block 10 is larger than the openings at both ends of the moving groove 7. This design prevents the stabilizing block 10 from coming off at both ends of the moving groove 7, and also guides and stabilizes the limiting clamping column 8 during its movement, ensuring that the limiting clamping column 8 does not wobble when moving within the moving groove 7.

[0038] A spring 9 is wound around the outer wall of the limiting clamping post 8. The spring 9 is a helical compression spring, with one end fixedly connected to the limiting post 6 and the other end fixedly connected to the stabilizing block 10. When the limiting clamping post 8 is subjected to an outward pulling force, the spring 9 is compressed; when the pulling force disappears, the spring 9 generates a restoring force based on its elasticity, causing the limiting clamping post 8 to clamp the inner wall of the slide groove 4. After the position of the cylinder head fixing platform 3 is finely adjusted, the limiting clamping post 8 is released. The spring 9 will drive the limiting clamping post 8 to quickly reset within 0.5 seconds, so that the limiting clamping post 8 is tightly fitted again with the inner wall of the slide groove 4, thus fixing the slider 5 to the slide groove 4 and ensuring that the structure can be reused.

[0039] A silicone pad ring is provided on the outer wall of the spring 9. The silicone pad ring tightly wraps around the outer wall of the spring 9 and fits against the outer wall of the limiting clamping post 8. The silicone pad ring has good elasticity and wear resistance, and can effectively reduce the friction between the spring 9 and the surrounding parts during the repeated deformation of the spring 9.

[0040] A pull ball 12 is fixedly connected to the top of the limiting clamping column 8. The pull ball 12 is spherical, making it easy for the operator to hold. The surface of the pull ball 12 is provided with anti-slip texture, which is a series of intersecting grooves. By holding the pull ball 12, the operator can more easily pull the limiting clamping column 8. The anti-slip texture can also improve the operator's grip strength during operation, effectively preventing the product from slipping out of their hand.

[0041] A rubber clamping pad 11 is attached to the bottom of the limiting clamping post 8. The rubber clamping pad 11 is made of rubber material with a high coefficient of friction and fits against the inner wall of the slide groove 4. The rubber clamping pad 11 is shaped like an array of pyramids. This pyramidal design increases the contact area between the rubber clamping pad 11 and the surface of the slide groove 4, and at the same time increases the friction.

[0042] The outer wall of the limiting post 6 is fitted with a stabilizing bearing 13, which is a deep groove ball bearing. Its inner diameter is tightly fitted with the outer wall of the limiting post 6, and its outer diameter is in contact with the inner surface of the upper end of the slide groove 4. When the slider 5 moves on the inner wall of the slide groove 4, the limiting post 6 will move at the opening at the upper end of the slide groove 4. The setting of the stabilizing bearing 13 converts the sliding friction between the limiting post 6 and the slide groove 4 into rolling friction.

[0043] Multiple sets of sliders 5 are provided at the bottom of the cylinder head fixing platform 3, and the number of sliders 5 and limit posts 6 are the same and correspond to each other. If there are 3 sets of sliders 5 at the bottom of the cylinder head fixing platform 3, then 3 sets of limit posts 6 are set accordingly. This corresponding arrangement makes the force on each position more uniform when the sliders 5 are fixed on the slide groove 4, and can better maintain the stability of the fixed state. According to actual tests, when grinding the cylinder head, the shaking amplitude of the cylinder head fixing platform 3 using this device is further reduced compared with the traditional device, which effectively improves the stability of the cylinder head fixing platform 3 on the moving table 2, thereby ensuring the high precision requirements of cylinder head surface grinding.

[0044] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
