Description

Technical Field

[0001] This invention relates to the field of polishing equipment technology, specifically to an integrated polishing machine for the end face and edges of stainless steel water bath pipes. Background Technology

[0002] Stainless steel water bath pipes are widely used in heating or cooling systems in industries such as chemical, medical, and food processing. The processing quality of their end faces and edges directly affects the pipes' sealing performance and service life. Currently, the polishing process for these pipes is typically carried out in a multi-step manner. For example, a separate edge polishing machine is first used to deburr and round the edges at both ends of the pipe. Then, the pipe is transferred to another end face polishing machine for fine grinding and polishing of the end faces to achieve the required surface roughness and flatness.

[0003] However, this traditional step-by-step processing method has significant drawbacks. First, the transfer and re-clamping of pipes between different devices consumes a considerable amount of time and manpower, resulting in low production efficiency and making it difficult to meet the demands of large-scale production. Second, multiple clamping operations can easily introduce positioning errors, affecting the relative positional accuracy of the pipe end face and edge, and consequently impacting the final polishing quality. Furthermore, during the polishing process, a large amount of metal shavings adhere to the abrasive belt and polishing wheel. If not cleaned promptly, these shavings will not only scratch the surface of the processed workpiece but also reduce the lifespan of the polishing tools. In existing technologies, cleaning the polishing tools typically requires manual labor or additional pneumatic equipment after machine shutdown, further increasing production downtime. Summary of the Invention

When the traveling mechanism drives the pipe to a set position, the trigger opening mechanism will activate the rotation mechanism and the second polishing mechanism. The rotation mechanism is used to drive the pipe to rotate, and the second polishing mechanism is used to polish the end face of the pipe. A grinding wheel cleaning assembly includes an energy conversion mechanism and an air jet cleaning mechanism.

[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] Please see Figures 1-8 The present invention provides a technical solution: An integrated polishing machine for the end face and edges of stainless steel water bath pipes, as per the instruction manual. Figure 1 As shown, the device includes a workbench 1, on which a processing rack 2 is mounted. The workbench 1 serves as the supporting foundation for the entire device, while the processing rack 2 is used to install and support other functional components.

[0019] The conveying assembly includes a clamping mechanism and a traveling mechanism. The clamping mechanism is used to clamp and fix the pipe, and the traveling mechanism is used to drive the clamping mechanism to move linearly along the processing frame 2. In this embodiment, the clamping mechanism is symmetrically arranged on both sides of the processing frame 2. The clamping mechanism includes a pneumatic chuck 3 and a mounting base 4. The traveling mechanism includes a linear guide rail 5, a traveling screw 6 and a drive motor 7. The linear guide rail 5 is laid along the direction of pipe movement. The traveling screw 6 is connected to the drive motor 7. The mounting base 4 is fixedly connected to the nut of the traveling screw 6 and is slidably set on the linear guide rail 5. The pneumatic chuck 3 is fixedly installed on the mounting base 4. The pneumatic chuck 3 is used to tighten and fix the pipe from the inside (i.e., an internal support chuck) to ensure the stability of the pipe during transportation and processing. When the drive motor 7 works, it drives the traveling screw 6 to rotate, thereby driving the mounting base 4 and the pneumatic chuck 3 on it and the pipe to move along the linear guide rail 5.

[0020] The edge polishing assembly includes an adjustment mechanism and a grinding mechanism. The grinding mechanism is symmetrically arranged on both sides of the processing frame 2. The grinding mechanism is used to polish the edges of both ends of the pipe. The adjustment mechanism is used to adjust the distance between the two grinding mechanisms. In this embodiment, the adjustment mechanism includes an adjustment motor 8, an adjustment screw 9, and an adjustment seat 10. The adjustment motor 8 is fixed on the worktable 1, and its output end is connected to the adjustment screw 9. The adjustment screw 9 is a positive and negative thread screw, and two adjustment seats 10 are respectively connected to it through two screw nuts. The two adjustment seats 10 are symmetrically arranged. When the adjustment motor 8 drives the adjustment screw 9 to rotate, the two adjustment seats 10 will move closer or further away from each other along the axial direction of the adjustment screw 9. A grinding mechanism is installed above each adjustment seat 10. In this embodiment, the adjustment motor 8, the first grinding motor 15, the rotary motor 21, and the second grinding motor 23 are all geared motors.

[0021] The first grinding mechanism is used to grind and polish the edges of the pipe. In this embodiment, the first grinding mechanism includes a belt sander bracket 11, a drive wheel 12, a driven wheel 13, a sanding belt 14, and a first grinding motor 15. The belt sander bracket 11 is fixedly mounted on the adjusting seat 10. The drive wheel 12 and the driven wheel 13 are rotatably mounted on the belt sander bracket 11. The sanding belt 14 is wound around the drive wheel 12 and the driven wheel 13. The first grinding motor 15 is used to drive the drive wheel 12 to rotate, thereby driving the sanding belt 14 to rotate at high speed to grind the edges of the pipe. In order to ensure the tension of the sanding belt 14, the first grinding mechanism also includes a wheel bracket 16, a tensioning wheel 17, and a tension spring 18. The wheel bracket 16 is rotatably connected to the belt sander bracket 11. The tensioning wheel 17 is mounted on the wheel bracket 16. The sanding belt 14 is also wound around the tensioning wheel 17. The tension spring 18 is sleeved on the outside of the compression rod 19 and keeps the wheel bracket 16 in a tensioned state through elasticity.

[0022] The end-face polishing assembly includes a trigger opening mechanism, a rotation mechanism, and a second grinding mechanism. The trigger opening mechanism is mounted on the processing frame 2 and is used to detect whether the pipe has moved to the processing position. In this embodiment, the trigger opening mechanism is a distance sensor 20, which is fixedly mounted on the processing frame 2 and is used to detect the position of the mounting seat 4. When the traveling mechanism drives the pipe to the set position, in this embodiment, the distance sensor 20 is located on one side of the processing frame 2 (that is, when the mounting seat 4 reaches above the distance sensor 20, the first grinding mechanism has already completed the grinding of the pipe edge). At this time, the distance sensor 20 sends a signal to start the rotation mechanism and the second grinding mechanism.

[0023] The rotating mechanism is used to drive the pipe to rotate around its axis so that the grinding mechanism can process the entire end face of the pipe. The rotating mechanism includes a rotary motor 21, which is fixedly installed on the mounting base 4. Its output end is connected to the pneumatic chuck 3. The rotary motor 21 is used to drive the pneumatic chuck 3 and the pipe it holds to rotate.

[0024] The second grinding mechanism is used to grind the end face of a rotating pipe. The second grinding mechanism includes a grinding mold support 22, a second grinding motor 23, and a polishing roller 24. The grinding mold support 22 is fixedly mounted on the mounting base 4. The polishing roller 24 is rotatably mounted on the grinding mold support 22. The second grinding motor 23 is fixed on the grinding mold support 22 and is used to drive the polishing roller 24 to rotate at high speed to grind the end face of the pipe.

[0025] The grinding wheel cleaning assembly includes an energy conversion mechanism and an air jet cleaning mechanism for automatically cleaning debris from grinding mechanism one and grinding mechanism two. The energy conversion mechanism converts the vibration generated during the operation of grinding mechanism one into compressed air and stores it. The energy conversion mechanism includes a compression rod 19, a compression cylinder 25, and an air tank 26. One end of the compression rod 19 is rotatably connected to the wheel bracket 16. The piston end of the compression rod 19 is located inside the compression cylinder 25. The end of the compression cylinder 25 away from the compression rod 19 is rotatably connected to the belt sander bracket 11. A tension spring 18 is sleeved on the outside of the compression rod 19 and abuts between the wheel bracket 16 and the compression cylinder 25. When the belt sander bracket 11 undergoes relative displacement due to grinding vibration, the wheel bracket 16 will produce a small reciprocating motion relative to the compression cylinder 25, driving the compression rod 19 to reciprocate within the compression cylinder 25, thereby compressing the air. The compression cylinder 25 is connected to the air tank 26 through a pipe, and the compressed air is stored in the air tank 26.

[0026] The air jet cleaning mechanism is used to clean the first and second grinding mechanisms using compressed air stored in the air tank 26. In this embodiment, the air jet cleaning mechanism includes an electromagnetic control valve 27, a mounting bracket 28, and a nozzle 29. The air tank 26 is provided with several air jet ports, and each air jet port is provided with an electromagnetic control valve 27 to control the opening and closing of the air path. The electromagnetic control valve 27 is connected to the nozzle 29 through a pipe (the airflow delivery pipe is existing technology, and the type and material of the pipe can be reasonably selected according to the actual situation, as long as it does not interfere with the operation of the first and second grinding mechanisms). The mounting bracket 28 is set on the belt sander bracket 11 and is used to install the nozzle 29 aligned with the first grinding mechanism. At the same time, a nozzle 29 for aligning with the second grinding mechanism (polishing roller 24) is also provided on the mounting base 4. When cleaning is required, the electromagnetic control valve 27 is opened, and compressed air is sprayed out through the nozzle 29 to blow away the debris attached to the sanding belt 14 and the polishing roller 24.

[0027] Working principle: During operation, the two ends of the pipe are first fixed by the pneumatic chucks 3 on both sides. Then, the adjusting motor 8 drives the adjusting screw 9 according to the pipe diameter, so that the grinding mechanism 1 on both sides contacts the edge of the pipe. The grinding motor 15 drives the sanding belt 14 to polish the edge of the pipe. Then, the drive motor 7 is started, and the pipe is moved slowly through the travel screw 6 (when polishing the edge of the pipe, the rotary motor 21 is in a stopped state. At this time, the pipe will rotate under the friction of the sanding belt 14 to polish the entire edge). When the distance sensor 20 detects that the mounting base 4 has reached the set position, it triggers the rotary motor 21 to drive the pipe to rotate. At the same time, the grinding motor 23 drives the polishing roller 24 to polish the end face of the pipe.

[0028] During edge polishing, the vibration generated by the belt sander bracket 11 drives the compression rod 19 to move within the compression cylinder 25, continuously filling the air tank 26 with air. When cleaning is required (or when the sanding belt 14 and polishing roller 24 need to be cooled during operation), the corresponding electromagnetic control valve 27 is opened, and the nozzle 29 sprays air to remove debris from the sanding belt 14 or polishing roller 24, ensuring polishing quality and equipment lifespan.
