Description

Technical Field

[0001] This utility model relates to the field of gate plate processing technology, specifically a planetary grinding machine for gate plate grinding. Background Technology

[0002] In industrial production, gate valves are important components widely used in various piping systems, valve devices, and other equipment. The surface quality of the gate valve has a crucial impact on its sealing performance, service life, and the overall operational stability of the equipment. Therefore, high-quality grinding of the gate valve is a key step in ensuring its performance.

[0003] Currently, in the field of gate plate grinding, there are various types of existing grinding equipment and methods. Some traditional grinding equipment uses a single grinding disc to grind the gate plate. This method has low grinding efficiency, and it takes a long time to grind one gate plate, which cannot meet the needs of large-scale production. For example, in some small processing plants, when using a single-disc grinding machine to grind gate plates, it may take several hours to grind each gate plate, which seriously affects the production schedule.

[0004] Some devices use multiple grinding discs, but the movement of the grinding discs is relatively simple, consisting of only linear reciprocating motion or single rotational motion. This makes the grinding of the gate surface uneven, and it is easy to have local over-grinding or under-grinding, resulting in the gate surface flatness and smoothness failing to meet high standards.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] like Figure 1-4 As shown, this utility model provides a technical solution:

[0026] A planetary grinding machine for grinding gate plates includes a housing 1. A circular groove 2 is provided in the middle of the housing 1. A support column 3 is vertically arranged in the middle of the circular groove 2. A rotating mechanism is provided at the top of the support column 3. The rotating mechanism includes a turntable 15. The turntable 15 is movably arranged at the top of the support column 3 via a bearing. A semi-circular groove 16 is vertically arranged in the middle of the turntable 15. A semi-circular shaft 17 matching the semi-circular groove 16 is provided at the bottom of the middle of the sun gear 10. Several storage slots 18 are arranged at equal arcs at the upper end of the turntable 15. A waste discharge port 19 communicating with the circular groove 2 is provided in the middle of the front of the housing 1. Several connecting parts 20 are arranged at equal arcs between the circular groove 2 and the support column 3. Several triangular scrapers 21 are provided on the outer wall of the turntable 15. A waste box 22 is movably arranged at the bottom of the middle of the front of the housing 1. The planetary grinding mechanism cooperates with the rotating mechanism.

[0027] In this embodiment, by setting a triangular scraper 21 on the outside of the turntable 15, the waste generated by grinding can be automatically scraped into the waste box 22, realizing automatic cleaning of waste. This solves the problems of waste accumulation affecting grinding work and tedious manual cleaning in the prior art, and effectively improves the overall performance and production efficiency of the equipment.

[0028] like Figure 3 As shown, a frame 4 is installed at the top center of the chassis 1, and a planetary grinding mechanism is installed at the lower center of the frame 4. The planetary grinding mechanism includes a planet carrier 9, which is located at the upper end of the inner side of the transmission housing 6. A sun gear 10 is located at the lower center of the planet carrier 9, and four planet gears 11 are located at the bottom of the planet carrier 9 and outside the sun gears 10. A gear ring 12 is located outside the planet gears 11, meshing with the planet gears 11. The planet gears 11 mesh with the sun gear 10, and the gear ring 12 is slidably connected to the inner wall of the transmission housing 6. The planetary grinding mechanism also includes a motor 1. 3. A motor 13 is fixedly installed at the top of the transmission housing 6. The output shaft of the hydraulic rod 5 is fixedly set at the upper end of the motor 13. The output shaft of the motor 13 is fixedly connected to the sun gear 10. A grinding disc 14 is fixedly installed at the bottom middle part of the planetary gear 11 through a rotating shaft. A lifting mechanism is set between the frame 4 and the planetary grinding mechanism. The lifting mechanism includes a hydraulic rod 5. The hydraulic rod 5 is fixedly installed at the top middle part of the frame 4. The output shaft end of the hydraulic rod 5 is provided with a transmission housing 6. Guide rods 7 are provided at the top two sides of the transmission housing 6. Guide grooves 8 that match the guide rods 7 are provided on both sides of the top of the frame 4.

[0029] In this embodiment, multiple grinding discs 14 are driven by a planetary principle. The simultaneous operation of multiple grinding discs 14 greatly improves grinding efficiency. Furthermore, the compound motion of the planetary gears 11 driving the grinding discs 14 makes the grinding more uniform, effectively solving the problems of low grinding efficiency and uneven grinding in the prior art. At the same time, through a unique design, the workpiece rotates in the opposite direction to the grinding discs 14, increasing relative motion and making the grinding force distribution more uniform, further improving the grinding quality and avoiding inconsistent grinding marks on the gate plate surface.

[0030] Working principle: During operation, motor 13 starts, and its output shaft drives the sun gear 10 connected to it to rotate. Because the sun gear 10 meshes with planet gears 11, the planet gears 11 begin to revolve around the sun gear 10 and rotate on their own axis. This causes the grinding disc 14, fixed at the bottom center of the planet gears 11, to produce a combined motion of revolution and rotation. At the same time, the hydraulic rod 5 on the frame 4 operates, and its output shaft pushes the transmission housing 6 to descend smoothly along the guide rod 7 and guide groove 8, bringing the grinding disc 14 close to the gate plate workpiece placed in the storage slot 18 of the turntable 15 and beginning grinding. Furthermore, because the semi-circular shaft 17 at the bottom of the sun gear 10 matches the semi-circular groove 16 in the middle of the turntable 15, the rotation of the sun gear 10 drives the turntable 15 to rotate around the support column 3, allowing all parts of the gate plate to be ground evenly. During the rotation of the turntable 15, the triangular scraper 21 on its outer wall scrapes the waste generated during grinding into the circular groove 2. The waste falls into the waste box 22 through the waste discharge port 19, thereby achieving efficient grinding of the gate and cleaning of waste.

[0031] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
