Description

Technical Field

[0001] This utility model specifically relates to a device for precision grinding of the piston rod surface of a cylinder. Background Technology

[0002] Cylinders, as pneumatic actuators that convert the pressure energy of compressed air into mechanical energy, are widely used in many fields such as industrial automation, machinery manufacturing, and transportation. The piston rod, as a key component of the cylinder, bears the important task of transmitting force and motion; its surface quality directly affects the cylinder's performance and service life.

[0003] In actual operation, the piston rod needs to perform reciprocating linear motion within the cylinder, frequently rubbing against components such as seals. If the piston rod surface roughness is too high, it will exacerbate the wear of the seals, leading to air leakage in the cylinder and reducing its efficiency and stability. Simultaneously, a rough surface easily attracts dust and impurities, further accelerating the wear process. Conversely, if the piston rod surface has high precision and good surface quality, it can effectively reduce frictional resistance, decrease wear, improve the cylinder's sealing performance and service life, and ensure stable and reliable operation of the cylinder under various complex working conditions. Therefore, precision grinding of the cylinder piston rod surface to achieve high precision and surface quality requirements is a crucial step in ensuring cylinder performance.

[0004] Currently, common piston rod surface machining methods mainly include traditional machining methods such as turning and grinding. Although turning can quickly remove most of the excess material from the piston rod surface, its machining accuracy and surface roughness are often insufficient to meet the requirements of high-precision cylinders, and subsequent grinding is usually required to further improve the surface quality.

[0005] Grinding is one of the main methods to improve the surface quality of piston rods, and traditional grinding methods mostly use ordinary grinding machines. However, ordinary grinding machines have many limitations in the processing. On the one hand, the positioning and clamping methods of ordinary grinding machines are relatively simple, making it difficult to ensure the precise position and stability of the piston rod during processing. This can easily lead to dimensional and positional errors such as cylindricity and straightness in the machined piston rod, affecting the assembly accuracy and operational stability of the cylinder. On the other hand, the grinding parameters of ordinary grinding machines are not flexible enough, making it difficult to make precise adjustments according to different materials, specifications of piston rods, and different processing requirements. This results in low processing efficiency and makes it difficult to guarantee consistent processing quality. Utility Model Content

The piston rod is fixedly clamped by a clamping mechanism. According to different models and specifications of piston rods, the grinding mechanism is raised to the corresponding grinding position through a height adjustment mechanism to grind the surface of the clamped piston rod. This solves the problem that ordinary grinding machines are not flexible enough in adjusting grinding parameters, making it difficult to make precise adjustments according to different materials, specifications of piston rods, and different processing requirements, resulting in low processing efficiency and difficulty in ensuring consistent processing quality.

Detailed Implementation

[0021] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model. All other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of this utility model.

[0022] Combination Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a piston rod surface grinding device for a cylinder includes a worktable 1, a clamping mechanism 2 for fixing and holding the piston rod on the worktable 1, a grinding mechanism 3 for grinding the piston rod surface on the outside of the clamping mechanism 2, and a height adjustment mechanism 4 for adjusting its height.

[0023] This utility model proposes a cylinder piston rod surface fine grinding device. The worktable 1 serves as the basic support platform for the entire device, providing a position for the installation and fixing of other components. It is the carrier of the entire device and ensures the stability of the device during operation.

[0024] Clamping mechanism 2 is mounted on the worktable 1 and is used to fix and clamp the piston rod. Through a reasonable clamping design, the piston rod is ensured to remain in a fixed position during grinding, preventing shaking or displacement, thus ensuring grinding accuracy and quality. Clamping mechanism 2 can be adjusted according to the size and shape of the piston rod to accommodate the clamping requirements of piston rods of different specifications.

[0025] The grinding mechanism 3 is located outside the clamping mechanism 2 and is responsible for grinding the surface of the piston rod. The grinding mechanism 3 typically includes grinding tools such as a grinding head, which contact the piston rod surface through high-speed rotation or other motion to remove burrs and uneven parts, so that the piston rod surface achieves the required precision and smoothness.

[0026] The height adjustment mechanism 4 is connected to the grinding mechanism 3, and its function is to adjust the height of the grinding mechanism 3. Since different piston rods may have different diameters, or in order to meet different grinding process requirements, it is necessary to adjust the relative position of the grinding mechanism 3 and the piston rod surface. The height adjustment mechanism 4 can achieve this function, ensuring that the grinding mechanism 3 is always at a suitable grinding height so as to achieve effective grinding of the piston rod surface.

[0027] When using the piston rod surface precision grinding device for this cylinder, the piston rod to be ground is first placed on the worktable 1 and firmly clamped by the clamping mechanism 2 to ensure the stability of the piston rod during operation. Then, according to the diameter of the piston rod and the grinding process requirements, the height of the grinding mechanism 3 is precisely adjusted using the height adjustment mechanism 4 to ensure that the grinding head of the grinding mechanism 3 is in a suitable contact position with the piston rod surface. After adjustment, the grinding mechanism 3 is started, and the grinding head begins to work, grinding the piston rod surface through rotation or other motion. During the grinding process, because the piston rod is stably clamped, the grinding mechanism 3 can uniformly process the piston rod surface, removing surface defects and improving the quality and precision of the piston rod surface. The entire device, through the coordinated work of its components, achieves efficient and precise grinding of the cylinder piston rod surface.

[0028] Combination Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the clamping mechanism 2 includes a fixed frame 21 disposed on one side of the workbench 1. A clamping cylinder 22 is disposed on the fixed frame 21. A clamping motor 23 is connected to the output end of the clamping cylinder 22. A clamping plate 24 is connected to the output end of the clamping motor 23. A clamping block 25 for clamping the end of the piston rod is connected to the clamping plate 24.

[0029] Specifically, the fixing frame 21 is set on one side of the workbench 1, providing a stable installation position for other components, ensuring that the entire clamping mechanism 2 maintains a relatively fixed position during operation and will not shake due to external forces or equipment operation, thereby ensuring the accuracy of clamping.

[0030] The clamping cylinder 22 is mounted on the fixed frame 21 and is one of the power sources of the clamping mechanism 2. The clamping cylinder 22 can generate linear motion by compressed air, and the movement of its output end can drive the subsequent components to perform corresponding actions, providing initial power for the clamping piston rod.

[0031] The clamping motor 23 is connected to the output end of the clamping cylinder 22. The clamping motor 23 can rotate upon receiving a control signal, giving the clamping mechanism 2 greater functional flexibility. The clamping motor 23 can also drive the piston rod to rotate.

[0032] The clamping plate 24 is connected to the output end of the clamping motor 23. The clamping plate 24 further transmits and converts the rotational motion of the clamping motor 23 or the displacement caused by the clamping cylinder 22, providing a suitable motion trajectory and force for the clamping block 25.

[0033] The clamping block 25 is attached to the clamping plate 24 and is the component that directly contacts and clamps the end of the piston rod. The shape and material of the clamping block 25 are usually designed according to the shape and characteristics of the piston rod to ensure that the end of the piston rod can be firmly and stably clamped while avoiding damage to the surface of the piston rod.

[0034] Combination Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, the grinding mechanism 3 includes a mounting frame 31 disposed on the outside of the clamping mechanism 2, a grinding motor 32 disposed on the mounting frame 31, and a grinding roller 33 connected to the output end of the grinding motor 32.

[0035] Specifically, the mounting bracket 31 is located on the outside of the clamping mechanism 2. It provides a stable mounting position for the entire grinding mechanism 3, ensuring that the grinding mechanism 3 remains relatively fixed during operation and will not shake or shift due to vibrations or other external forces generated by the operation of the equipment, thereby ensuring the accuracy and quality of grinding.

[0036] The grinding motor 32 is mounted on the mounting bracket 31 and is the power core of the grinding mechanism 3. The grinding motor 32 can convert electrical energy into mechanical energy to provide power for the rotation of the grinding roller 33.

[0037] The grinding roller 33 is connected to the output end of the grinding motor 32 and is the component that directly contacts the surface of the piston rod to perform the grinding operation. The surface of the grinding roller 33 is usually specially treated according to the grinding requirements, such as embedding abrasive particles or wrapping abrasive materials such as sandpaper.

[0038] Combination Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, the height adjustment mechanism 4 includes a lifting motor 41 located at the bottom of the workbench 1, and the output end of the lifting motor 41 is fixedly connected to the mounting bracket 31.

[0039] Specifically, the lifting motor 41 is located at the bottom of the worktable 1. The lifting motor 41 outputs rotational power in different directions according to control commands to achieve the rising or falling movement of the mounting frame 31. The output end of the lifting motor 41 is fixedly connected to the mounting frame 31. During the operation of the lifting motor 41, the power at the output end can be stably and effectively transmitted to the mounting frame 31, causing the mounting frame 31 to rise or fall synchronously with the movement of the output end. The mounting frame 31 serves as the supporting structure of the grinding mechanism 3, and its height change directly determines the relative position of the grinding roller 33 and the piston rod surface in the grinding mechanism 3.

[0040] Combination Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a slide rail 11 is provided on the workbench 1, and a groove 241 matching the slide rail 11 is provided on the bottom of the clamping plate 24.

[0041] Specifically, the slide rail 11 is mounted on the worktable 1. The slide rail 11 has a precise shape and dimensions, with a smooth surface and high geometric accuracy in terms of straightness and parallelism, providing stable and precise guidance for the sliding of the clamping plate 24. The clamping plate 24 connects to the clamping block 25 and drives its movement to clamp the piston rod. A groove 241 is formed at the bottom of the clamping plate 24, and its shape and dimensions match the slide rail 11. The gap between the groove 241 and the slide rail 11 is moderate, allowing the clamping plate 24 to slide smoothly on the slide rail 11 while preventing wobbling due to excessive gap, which would affect the clamping accuracy and stability.

[0042] Combination Figure 1 , Figure 2 and Figure 3 As shown, a control panel 5 is installed on the workbench 1.

[0043] Specifically, control panel 5 is installed on workbench 1 and serves as the crucial interface for operators to interact with the grinding equipment. Control panel 5 typically uses an LCD or touchscreen display to show the equipment's operating status, grinding parameters, fault information, etc. Operators can intuitively understand the equipment's working condition through the display and perform corresponding operations and adjustments as needed.

[0044] Combination Figure 1 , Figure 2 and Figure 3 As shown, a switch button 6 is provided on the workbench 1.

[0045] Specifically, the switch button 6 is installed on the surface of the workbench 1 for easy access by the operator. When it is necessary to start the fine grinding device to grind the cylinder piston rod, the operator presses the start button part of the switch button 6. At this time, the lifting motor 41 drives the mounting frame 31 and the grinding mechanism 3 to rise to a suitable working height; the grinding motor 32 starts to rotate, driving the grinding roller 33 to rotate at high speed; the clamping cylinder 22 pushes the clamping plate 24 and the clamping block 25 to move, clamping the piston rod, thereby starting the entire fine grinding device to begin grinding the piston rod.

[0046] Combination Figure 1 , Figure 2 and Figure 3 As shown, support legs 7 are provided at the four corners of the bottom of the workbench 1.

[0047] Specifically, the support legs 7 are installed at the four corners of the bottom of the workbench 1, serving as the support components between the entire device and the ground. Anti-slip components, such as rubber pads or anti-slip feet, may be installed on the bottom of the support legs 7. These anti-slip components increase the friction between the support legs 7 and the ground, preventing the device from sliding due to vibration or external forces during operation, thus further improving the stability of the device.

[0048] The above embodiments only illustrate one or more implementations of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
