Description

Technical Field

[0001] This utility model relates to the field of piston ring processing technology, and in particular to a piston ring processing and grinding device. Background Technology

[0002] Piston ring machining is a critical precision process in the manufacturing of core engine components. Its purpose is to process the raw piston ring blank into a final product that meets strict dimensional and performance requirements. This process typically includes multiple steps such as turning, grinding, heat treatment, and polishing. The key is to precisely control the inner and outer diameters, height, elasticity, and crucial surface roughness of the piston rings. In particular, the grinding process requires extremely high roundness, parallelism, and smoothness to ensure that the piston rings can fit tightly against the cylinder wall and effectively achieve sealing, heat dissipation, and oil distribution functions. The entire machining process has extremely high precision requirements. Any slight deviation may lead to a decrease in engine performance or premature wear. Therefore, it is an important link that reflects the level of manufacturing technology. Piston ring machining and grinding equipment is a special equipment specifically designed for the precision machining and surface treatment of engine piston rings.

[0003] Traditional grinding equipment often lacks an efficient filtration system, which means that the metal shavings that accumulate in the coolant cannot be effectively removed. The coolant quickly becomes cloudy and loses its proper lubrication and cooling performance. This frequent contamination not only requires frequent coolant replacement, increasing operating costs and downtime, but also means that heavily contaminated coolant cannot provide good lubrication and heat dissipation, which reduces grinding efficiency and may even accelerate the wear of the grinding tools. In addition, due to the lack of effective filtration, the shavings in the coolant can easily clog the water pump, connecting pipes, and nozzles. This not only reduces the actual cooling and shaving removal effect, but may also increase the load on the water pump or even damage it, ultimately increasing the frequency and cost of maintenance and repair.

[0004] Therefore, those skilled in the art have provided a piston ring processing and grinding apparatus to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies and provide a piston ring processing and grinding device. The design of the trough allows water and metal shavings generated during grinding to quickly fall into the filter frame below, preventing accumulation in the grinding area and thus improving processing quality and efficiency. The filter frame filters the circulating coolant, ensuring its cleanliness, extending its service life, and protecting the water pump, downstream pipes, and nozzles from blockages.

[0006] To achieve the above objectives, this utility model provides a piston ring processing and grinding device, including a base plate, a mounting plate, and a grinding chamber. The lower end of the grinding chamber is fixedly connected to the upper surface of the mounting plate. Multiple slots are formed in the middle of the upper surface of the mounting plate. A protective shell is fixedly connected to the inner wall of the middle part of the mounting plate. A servo motor is fixedly connected to the inner bottom surface of the protective shell. A rotating disk is fixedly connected to the output end of the servo motor. A sleeve rod is fixedly connected to the middle of one side of the upper surface of the rotating disk. A water tank is fixedly connected to the middle of the upper surface of the base plate. An installation groove is formed in the upper part of the front end of the water tank. A filter frame is set inside the installation groove. The upper surface of the filter frame is tightly fitted to the lower surface of the base plate. Water pumps are fixedly connected to both sides of the outer wall of the grinding chamber. The suction ports of the water pumps are all connected to the interior of the lower end of the water tank through pipes. The outlet ports of the water pumps are all connected to connecting pipes. The upper end of each connecting pipe passes through the grinding chamber to the interior of the grinding chamber and is fixedly connected to a nozzle.

[0007] Through the above technical solution, the water pump draws coolant from the water tank and sprays it onto the grinding area through connecting pipes and nozzles. The trough design allows water and metal shavings generated during grinding to quickly fall into the filter frame below, preventing accumulation in the grinding area and affecting processing quality and efficiency. The filter frame filters the circulating coolant, ensuring that the coolant remains clean and extending its service life.

[0008] Furthermore, an electric push rod is fixedly connected to the middle of the upper surface of the grinding chamber, and an electric telescopic rod is fixedly connected to the middle of both sides of the inner wall of the grinding chamber. A grinding mechanism is fixedly connected to the output end of both the electric push rod and the electric telescopic rod. The grinding mechanism is located at the upper end and both sides of the sleeve rod, respectively.

[0009] The above technical solution uses an electric push rod to control the vertical feed, which controls the grinding mechanism to move up and down to adjust the grinding pressure or perform axial grinding. An electric telescopic rod controls the horizontal feed, which controls the grinding mechanisms on both sides to move toward the piston rings to achieve grinding of different parts. Electric drive replaces manual operation, reducing the labor intensity of operators and improving work efficiency.

[0010] Furthermore, a PLC control panel is fixedly connected to the outer wall of one side of the front end of the mounting plate;

[0011] The above technical solution uses a PLC control panel to control the operation of the entire equipment.

[0012] Furthermore, support rods are fixedly connected to the four corners of the upper surface of the base plate, and the upper ends of the support rods are fixedly connected to the four corners of the lower surface of the mounting plate.

[0013] The above technical solution forms a stable frame structure by rigidly connecting the four corners, which helps to improve the deformation resistance of the entire device and reduce swaying, vibration or structural deformation that may occur during stress or operation.

[0014] Furthermore, the lower surface of the rotating disk rotates and fits into contact with the middle part of the upper surface of the mounting plate;

[0015] The above technical solution provides a stable and reliable fulcrum for the rotating disk on the mounting plate, which is a key connection method to realize the subsequent rotation function and ensures the accuracy and smoothness of the rotation.

[0016] Furthermore, sliding grooves are provided on both sides of the inner wall of the mounting groove, and sliding plates are fixedly connected to both sides of the outer wall of the filter frame. The outer wall of the filter frame is tightly fitted with the inner wall of the mounting groove, and the outer walls of the sliding plates are slidably fitted with the inner walls of the sliding grooves. A handle is fixedly connected to the outer wall of the front end of the filter frame.

[0017] The above technical solution allows the filter frame to be easily pushed in and pulled out along the sliding groove. With the handle fixed at the front end, operators can easily pull out the filter frame for cleaning or filter replacement without disassembling complex fasteners, thus shortening maintenance time and improving equipment maintenance efficiency. In addition, the cooperation between the sliding groove and the sliding plate provides a good guiding effect.

[0018] Furthermore, the nozzles are located on both sides of the upper part of the grinding chamber;

[0019] By using the above technical solution, and by placing the nozzles on both sides of the upper part of the grinding chamber, it can be ensured that the coolant can be sprayed simultaneously and evenly from two directions onto the high-speed rotating piston rings and the grinding tool being ground. This symmetrical spraying method avoids the uneven cooling that may be caused by single-point spraying, making the temperature control of the entire grinding area more stable and the lubrication more sufficient, thereby improving the grinding quality and efficiency.

In addition, the cooperation between the sliding groove 502 and the sliding plate 601 plays a good guiding role. The nozzles 702 are located on both sides of the upper end of the grinding chamber 4. By setting the nozzles 702 on both sides of the upper end of the grinding chamber 4, it can be ensured that the coolant can be sprayed simultaneously and evenly from two directions onto the high-speed rotating piston ring and the grinding tool being ground. This symmetrical spraying method avoids the uneven cooling that may be caused by single-point spraying, making the temperature control of the entire grinding area more stable and the lubrication more sufficient, thereby improving the grinding quality and efficiency.

[0033] Working principle: First, the piston ring to be processed is installed and fixed on the sleeve 302 on the upper surface of the rotating disk 301. The rotating disk 301 rotates stably under the drive of the servo motor 3 by rotating its lower surface in contact with the middle of the mounting plate 2. Then, the operator starts the equipment through the PLC control panel 201. The servo motor 3 starts running, driving the rotating disk 301 and the piston ring fixed on it to rotate at the preset speed to prepare for grinding. At the same time, the water pump 7 also starts working, drawing coolant from the water tank 5. The water pump 7 cools the piston ring. Coolant is delivered through connecting pipe 701 to nozzles 702 on both sides of the upper end inside the grinding chamber 4. The nozzles 702 evenly spray the coolant onto the surface of the high-speed rotating piston ring and the grinding mechanism 402 that is about to contact it. The sprayed coolant, carrying grinding debris, falls into the drain groove 202 on the mounting plate 2. Simultaneously with the piston ring rotation, the electric push rod 401 and the electric telescopic rods 403 on both sides begin to work in tandem according to the program set on the PLC control panel 201. The electric push rod 401 controls the grinding mechanism 402 to feed vertically and adjust... The grinding pressure and axial grinding depth are controlled by the electric telescopic rod 403, which controls the horizontal feed of the grinding mechanisms 402 on both sides, so that the grinding wheel contacts the designated part of the piston ring. Through the cooperation of the two, the grinding mechanism 402 performs precision surface machining on the rotating piston ring. The metal shavings generated during the grinding process are mixed in the coolant and fall quickly into the filter frame 6 below through the trough 202. The filter frame 6 is slidably positioned in the sliding groove 502 of the mounting groove 501 by the sliding plates 601 on both sides, effectively filtering out the shavings and purifying the coolant. The filtered clean coolant flows back to the water tank 5 under gravity or subsequent pumping, forming a closed-loop cooling and chip removal system. The clean coolant is then pumped out again by the water pump 7 for recycling, ensuring continuous and effective cooling, lubrication, and chip removal. When the grinding of the piston ring surface reaches the preset precision and roughness requirements, the electric push rod 401 and the electric telescopic rod 403 drive the grinding mechanism 402 to return to the initial position, the servo motor 3 stops rotating, and the operator can stop the equipment operation through the PLC control panel 201 and remove the processed piston ring.

Although the present utility model has been described in detail with reference to the foregoing specific embodiments, those skilled in the art can still modify the technical solutions described in the foregoing specific embodiments or make equivalent substitutions for some of the technical features.
