Description

Technical Field

[0001] This utility model relates to the field of hydraulic component processing equipment technology, and in particular to an auxiliary grinding device for hydraulic component processing. Background Technology

[0002] The cylinder body of existing hydraulic components requires grinding during the manufacturing process. The hydraulic cylinder body is one of the key components in a hydraulic system, used to transmit and amplify mechanical forces. Grinding the hydraulic cylinder body during production is crucial to ensure its inner surface is smooth and defect-free, thereby improving the performance and lifespan of the hydraulic system. The main purpose of grinding the hydraulic cylinder body is to remove surface defects such as oxide layers, dirt, and scratches to improve its surface smoothness and precision. Simultaneously, grinding can also repair minor damage to the cylinder body surface, restoring its original geometry and dimensional accuracy.

[0003] Existing hydraulic cylinder grinding devices are specifically designed for grinding the inner or outer walls of hydraulic cylinders to improve surface quality and performance. Inner wall grinding devices are primarily used to grind the inner walls of hydraulic cylinders to remove surface defects such as dirt, scratches, and oxide layers. These devices typically employ automated control systems for precise control and monitoring of the grinding process. By setting grinding parameters and programs, uniform and efficient grinding of the cylinder's inner wall can be achieved. However, during grinding, the heat generated by friction raises the cylinder temperature. Existing grinding devices lack cooling mechanisms, leading to deformation or damage due to overheating. Therefore, we propose an auxiliary grinding device for hydraulic component processing. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides an auxiliary grinding device for processing hydraulic components, which solves the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: an auxiliary grinding device for processing hydraulic components, comprising: a base, an inner ring seat provided at the upper end of the base, a bottom rod fixedly connected between the inner ring seat and the base, an outer ring seat sleeved on the outer side of the inner ring seat and rotatably installed, and an annular limiting groove fixedly installed on the top of the outer ring seat.

[0006] The inner ring seat has a groove at its upper end. Multiple connecting shafts arranged in a circular array are rotatably mounted on the groove. Grinding wheels are fixedly mounted on the lower end of each connecting shaft, and driven wheels are fixedly mounted on the upper end of each connecting shaft. A first motor is fixedly mounted inside the groove. A driving wheel is fixedly mounted on the output shaft of the first motor. The driving wheel is located between the multiple driven wheels and is simultaneously engaged with the multiple driven wheels. A connecting frame passes through the inner ring seat. The upper end of the connecting frame is fixedly connected to the groove. A container is fixedly mounted at the bottom of the groove. Multiple side pipes are connected to and fixedly mounted on the outside of the container. The side pipes are respectively oriented towards the grinding wheels. Multiple oil outlet holes facing the grinding wheels are opened on the side pipes. The container is filled with lubricating fluid. A pressure pump is fixedly mounted at the bottom of the container.

[0007] As a further technical solution of this utility model, a connecting pipe is connected and fixedly installed on the container, and a valve is installed on the connecting pipe.

[0008] As a further technical solution of this utility model, a second motor is fixedly installed on the base, and a screw is fixedly installed on the output shaft end of the second motor. The screw passes through the lower end of the connecting frame and is threadedly connected to the connecting frame.

[0009] As a further technical solution of this utility model, an annular protective cover is fixedly installed on the base.

[0010] As a further technical solution of this utility model, an annular ring is fixedly installed on the top of the drive wheel, and a plurality of protrusions arranged in a circular array are fixedly installed on the outer side of the annular ring, with inclined surfaces provided at both ends of the protrusions.

[0012] This utility model provides an auxiliary grinding device for the processing of hydraulic components, which has the following advantages compared with the prior art:

[0013] 1. This design provides an auxiliary grinding device for processing hydraulic components. By filling a container with lubricating fluid, a pressure pump pressurizes the lubricating fluid in the container and forces it into a side pipe, which then discharges through multiple oil outlets. The lubricating fluid moves toward the grinding wheel and lubricates its surface. Simultaneously, as the grinding wheel rotates, the lubricating fluid can be poured onto different positions of the grinding wheel, providing comprehensive and uniform lubrication.

[0014] 2. This design relates to an auxiliary grinding device for hydraulic component processing. The lubricant reduces friction between the grinding wheel and the inner wall of the cylinder, thereby lowering the coefficient of friction and making the grinding process smoother. Reduced friction helps decrease wear on the grinding wheel, extending its service life, while also minimizing damage to the inner wall of the cylinder. The lubricant absorbs and carries away the heat generated during grinding, providing cooling and preventing thermal deformation or damage to the cylinder due to excessive temperature.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-4This utility model provides a technical solution for an auxiliary grinding device for processing hydraulic components: an auxiliary grinding device for processing hydraulic components includes: a base 1, an inner ring seat 2 is provided at the upper end of the base 1, a bottom rod 3 is fixedly connected between the inner ring seat 2 and the base 1, an outer ring seat 4 is sleeved on the outer side of the inner ring seat 2 and rotatably installed, and an annular limiting groove 5 is fixedly installed on the top of the outer ring seat 4. A groove 6 is provided at the upper end of the inner ring seat 2. Multiple connecting shafts 7 arranged in a circular array are rotatably mounted on the groove 6. Grinding wheels 8 are fixedly mounted at the lower end of each connecting shaft 7, and driven wheels 9 are fixedly mounted at the upper end of each connecting shaft 7. A first motor 10 is fixedly mounted inside the groove 6. A driving wheel 11 is fixedly mounted at the output shaft end of the first motor 10. The driving wheel 11 is located between the multiple driven wheels 9 and is simultaneously engaged with them. A connecting frame 12 passes through the inner ring seat 2, and its upper end is fixedly connected to the groove 6. A container 13 is fixedly mounted at the bottom of the groove 6. Multiple side pipes 14 are connected to and fixedly mounted on the outside of the container 13. The side pipes 14 are respectively oriented towards the grinding wheels 8 and have multiple oil outlet holes 15 facing the grinding wheels 8. The container 13 contains lubricating fluid, and a pressure pump 16 is fixedly mounted at the bottom of the container 13. A connecting pipe 17 is connected to and fixedly mounted on the container 13, and a valve is installed on the connecting pipe 17. During the polishing process, lubricating fluid is filled into container 13, and the lubricating fluid in container 13 is pressurized by pressure pump 16 and enters side pipe 14. The lubricating fluid is then discharged from multiple oil outlet holes 15. The lubricating fluid moves toward the polishing wheel 8 and lubricates the surface of the polishing wheel 8. At the same time, as the polishing wheel 8 rotates, the lubricating fluid can be poured onto different positions of the polishing wheel 8, so as to perform comprehensive and uniform lubrication treatment on the polishing wheel 8.

[0022] Among them, such as Figure 3 and Figure 4 As shown, a second motor 18 is fixedly installed on the base 1. A screw 19 is fixedly installed on the output shaft end of the second motor 18. The screw 19 passes through the lower end of the connecting frame 12 and is threadedly connected to the connecting frame 12. An annular protective cover 20 is fixedly installed on the base 1. An annular ring 21 is fixedly installed on the top of the drive wheel 11. Multiple protrusions 22 arranged in a circular array are fixedly installed on the outer side of the annular ring 21. Both ends of the protrusions 22 are provided with bevels. Multiple support rods 23 are fixedly installed in the groove 6. Spring telescopic rods 24 are installed on each support rod 23. The multiple spring telescopic rods 24 are arranged in a circular array around the annular ring 21. The annular ring 21 rotates synchronously with the drive wheel 11. During the rotation, the protrusion 22 will squeeze the movable end of the spring telescopic rod 24, causing the movable end of the spring telescopic rod 24 to contract. When the protrusion 22 separates from the movable end of the spring telescopic rod 24, the movable end of the spring telescopic rod 24 resets and impacts the annular ring 21, thereby causing the groove 6 and the grinding wheel 8 to vibrate, which helps to separate the metal debris attached to the surface of the grinding wheel 8 from the grinding wheel 8.

[0023] The working principle of this utility model is as follows: (See the schematic diagram of the device for reference.) Figure 1 As shown, the lower end of the cylinder is inserted into the annular limiting groove 5. The first motor 10 drives the drive wheel 11 to rotate. The drive wheel 11 drives multiple driven wheels 9 on the outside to rotate synchronously, which can drive the grinding wheel 8 to rotate. The grinding wheel 8 contacts the inner wall of the cylinder and performs grinding on the inner wall of the cylinder during rotation.

[0024] During the polishing process, lubricating fluid is filled into container 13, and the lubricating fluid in container 13 is pressurized by pressure pump 16 and enters side pipe 14. The lubricating fluid is then discharged from multiple oil outlet holes 15. The lubricating fluid moves toward the polishing wheel 8 and lubricates the surface of the polishing wheel 8. At the same time, as the polishing wheel 8 rotates, the lubricating fluid can be poured onto different positions of the polishing wheel 8, so as to perform comprehensive and uniform lubrication treatment on the polishing wheel 8.

[0025] Lubricant reduces friction between the grinding wheel and the inner wall of the cylinder, thereby lowering the coefficient of friction and making the grinding process smoother. Reduced friction helps decrease wear on the grinding wheel 8, extending its service life, while also minimizing damage to the inner wall of the cylinder. Lubricant absorbs and carries away the heat generated during grinding, acting as a cooling agent to prevent thermal deformation or damage to the cylinder due to overheating.

[0026] The annular ring 21 rotates synchronously with the drive wheel 11. During rotation, the protrusion 22 presses against the movable end of the spring telescopic rod 24, causing the movable end of the spring telescopic rod 24 to retract. When the protrusion 22 separates from the movable end of the spring telescopic rod 24, the movable end of the spring telescopic rod 24 returns to its original position and impacts the annular ring 21, thereby causing the groove 6 and the grinding wheel 8 to vibrate. This helps to separate the metal debris attached to the surface of the grinding wheel 8 from the grinding wheel 8. The second motor 18 drives the screw 19 to rotate, which can move the connecting frame 12 in the vertical direction, thereby moving the groove 6 and the grinding wheel 8 on the groove 6 up and down, allowing the grinding wheel 8 to move to different positions in the cylinder for grinding.

[0027] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model are implemented according to conventional methods in the art, unless otherwise specified or limited.
