Description

Technical Field

[0001] The present invention relates to the technical field of alloy copper tube processing, and in particular to a rolling inner wall grinding mechanism of an alloy copper tube and a control method thereof. Background Art

[0002] Alloy copper tube refers to a copper tube made of copper as the base metal and one or more other elements, such as zinc, nickel, silicon, and phosphorus. It has a variety of excellent properties and is widely used in many fields. The alloying elements added to the alloy copper tube can improve its corrosion resistance, so that it can maintain stable performance in different corrosive environments. For example, it is not easily corroded in seawater, chemical media and other environments, which extends its service life. It has high strength and hardness, can withstand certain pressure and external force, is not easy to deform and damage, and also has good toughness and wear resistance. It is suitable for various occasions that need to withstand certain mechanical stress.

[0003] Alloy copper tubes have the following excellent properties: Corrosion Resistance: The most prominent feature of alloy copper pipes in many industrial applications is their excellent corrosion resistance. Due to copper's natural corrosion resistance and the addition of alloying elements (such as zinc, aluminum, nickel, and silicon), alloy copper pipes' corrosion resistance is significantly enhanced. This is particularly evident in highly corrosive environments such as the ocean and chemical media. Common copper alloys, such as brass (copper-zinc alloy), bronze (copper-tin alloy), and nickel-copper alloys (such as monel), are all resistant to seawater corrosion and various acidic and alkaline environments, and are widely used in marine engineering, chemical equipment, and other fields.

[0004] Strength and Hardness: By adding elements such as aluminum, zinc, and nickel, alloy copper pipes not only maintain copper's excellent electrical conductivity but also significantly enhance their strength and hardness, enabling them to withstand greater mechanical pressure and external forces. In environments with heavy mechanical loads, such as automotive manufacturing and pipeline transportation, alloy copper pipes provide stable operation and extended service life.

[0005] Wear resistance and good toughness: Alloy copper tubes maintain their toughness and wear resistance even when subjected to friction. Their high surface hardness and internal toughness prevent them from breaking or becoming brittle due to external impact. Therefore, they effectively resist wear in high-friction environments, especially in mechanical equipment, extending component life.

[0006] Thermal and electrical conductivity: Although the addition of other elements may affect the thermal and electrical conductivity of alloy copper tubes, copper alloy tubes still maintain high thermal and electrical conductivity. In some special applications, alloy copper tubes still play an important role in environments where heat exchange and electrical conductivity are required, such as air conditioning systems and cooling systems in electronic and electrical equipment.

[0007] The main application areas of alloy copper tubes are as follows: Construction Industry: Alloy copper pipes are widely used in the construction industry, particularly in water supply, drainage, and HVAC systems. Their excellent corrosion resistance makes them widely used in hot and cold water pipes, fire protection systems, and air conditioning condenser tubes. Copper pipes not only have a long service life but also ensure clean water quality, preventing rust and contamination.

[0008] Marine Engineering: Copper alloy pipes are widely used in marine engineering due to their resistance to seawater corrosion. They are found in ship cooling systems, offshore platform piping systems, submersibles, and submarine pipelines. Nickel-containing copper alloys, such as monel, are particularly well-suited to maintaining a long service life in extremely harsh marine environments.

[0009] Automotive Manufacturing: Alloy copper tubes also have important applications in the automotive industry, particularly in engine cooling systems, air conditioning systems, and fuel lines. Alloy copper tubes possess excellent compressive strength and high-temperature resistance, enabling them to operate stably and continuously in the high-temperature and high-pressure environments of automobiles. Furthermore, their excellent thermal conductivity makes them an indispensable component of automotive cooling systems.

[0010] Aerospace: In the aerospace field, alloy copper tubes are widely used in fuel pipes, hydraulic systems, cooling systems, etc. of aircraft and spacecraft. These environments usually require materials to maintain stable performance under conditions of high temperature, high pressure and strong radiation, and alloy copper tubes just meet these requirements.

[0011] Chemical Industry: Due to their excellent corrosion resistance, copper alloy pipes are widely used in pipeline transportation systems in the chemical industry, especially in strong acid and alkaline environments. Copper alloy pipes can effectively prevent pipeline corrosion and leakage, ensuring the safe transportation of chemicals.

[0012] Electrical and electronic equipment: Alloy copper tubes are also widely used in the electrical and electronic industry due to their good electrical conductivity, especially in power cables, electronic equipment cooling systems and other fields. They can effectively conduct current and help dissipate heat, extending the service life of the equipment.

[0013] In the process of alloy copper tube processing, the rolling inner wall grinding mechanism of the alloy copper tube is one of the indispensable equipment. The rolling inner wall grinding mechanism of the alloy copper tube is a device used to grind the inner wall of the alloy copper tube. The motor drives the threaded rod to rotate, so that the threaded sleeve moves, and drives the movable seat to move, so that the grinding module is close to the inner wall of the alloy copper tube. The third motor drives the rotating shaft to rotate, so that the grinding roller rotates to grind the inner wall of the copper tube. At the same time, the driving part drives the gear ring to rotate, so that the circular plate drives the movable seat to rotate, so that the grinding component rotates in the copper tube and the inner wall is fully polished.

[0014] In the prior art, alloy copper tubes are processed and polished by the above-mentioned technical method. However, during the polishing process, it is limited to the process flow of one-way polishing. When the grinding tool and the specific area of the metal hole wall are continuously rubbed in one direction, polishing marks in the same direction are easily produced, thereby reducing the smoothness of the polishing. This problem is now solved by adjusting the direction of the pipe, but the two-way polishing process of the inner wall of the pipe cannot be performed simultaneously, and thus cannot meet the requirements of use. Summary of the Invention

[0015] In order to make up for the above shortcomings, the present invention provides a rolling inner wall grinding mechanism of an alloy copper tube and a control method thereof, aiming to improve the problem in the prior art that the bidirectional grinding process of the inner wall of the pipe cannot be performed synchronously.

[0016] In order to achieve the above object, the present invention adopts the following technical solutions: A rolling inner wall grinding mechanism for an alloy copper tube comprises a processing table and a connecting belt, wherein the top rear side of the processing table is fixedly connected to an external frame, the front side of the top wall of the processing table is fixedly connected to a servo motor, the output end of the servo motor is fixedly connected to a driving pulley, the front side of the external frame is rotatably connected to a driven pulley, the driving pulley is transmission-connected to the driven pulley through the connecting belt, the right side of the driving pulley is fixedly connected to a fixed rod, the left and right ends of the outer wall of the fixed rod are fixedly connected to gear 1, a plurality of gears 2 are equidistantly rotatably connected to the right side of the top of the processing table, the gears 2 are meshed with the gear 1, the top of the gear 2 is meshed with a gear ring, a sliding mechanism is provided on the left side of the top of the processing table, and the sliding mechanism is used to move the grinding equipment.

[0017] Furthermore, the sliding mechanism includes a worm, which is fixedly connected to the right side of the driven pulley, a worm wheel is rotatably connected to the top front side of the external frame, the worm wheel is meshed with the worm, an elliptical block is fixedly connected to the bottom of the worm wheel, a fixed plate is fixedly connected to the middle and lower part of the front side of the external frame, a spring is fixedly connected to the right side of the fixed plate, the right end of the spring is fixedly connected to a groove block, and the bottom of the groove block is fixedly connected to a fixed platform.

[0018] Furthermore, a driving motor is fixedly connected to the top of the fixing platform, and a grinding drill bit is fixedly connected to the output end of the driving motor.

[0019] Furthermore, the top right end of the processing table is fixedly connected to a limiting frame.

[0020] Furthermore, a copper tube is rotatably connected to the inner side of the limiting frame, and the copper tube is installed on the inner side of the gear ring.

[0021] Furthermore, a reinforcing rib is fixedly connected to the inner side of the external frame.

[0022] Furthermore, a plurality of legs are fixedly connected to the bottom of the processing table at equal intervals, and the ends of the legs are fixedly connected to a bottom plate.

[0023] Furthermore, a slider is fixedly connected to the bottom of the fixed table, a slide rail is fixedly connected to the left side of the top wall of the processing table, and the slider is slidably connected to the slide rail.

[0024] The control method of the grinding mechanism comprises the following steps: ①Install a gear ring on the outside of the copper tube, pass it through the limit frame to limit the position of the copper tube, and turn on the servo motor to drive the active pulley to rotate; ② The driving pulley rotates synchronously with the driven pulley through the connecting belt. The rotation of the driving pulley causes the fixed rod and gear 1 to rotate synchronously. The rotation of gear 1 meshes with gear 2, thereby driving gear 2 to rotate. The rotation of gear 2 meshes with the gear ring, thereby driving the gear ring and the copper tube to rotate synchronously. ③ Turn on the driving motor to drive the grinding drill to grind and rotate in the opposite direction of the copper pipe, and grind the inner wall of the copper pipe, and simultaneously perform the two-way grinding process of the inner wall of the copper pipe; ④ The rotation of the driven pulley causes the worm to rotate synchronously, and the rotation of the worm engages with the worm wheel to drive the worm wheel and the elliptical block to rotate. The rotation of the elliptical block pushes the groove block to move. The movement of the groove block pulls the spring to stretch, and at the same time, the fixed platform and the drive motor installed on the fixed platform move synchronously; ⑤ After the elliptical block leaves the range of the groove block, the spring synchronously pulls the groove block to reset. At the same time, the movement of the fixed table drives the slider to slide on the slide rail, planning the movement trajectory of the fixed table, thereby performing a mobile grinding process on the inner wall of the copper pipe.

[0025] The design process of this application is as follows: First, we identified the requirements for rolling inner wall grinding of alloy copper tubes and understood the functions that needed to be achieved during the process, such as the movement of the grinding equipment, the design of the transmission system, and the precise grinding effect. Through analyzing these requirements, we formed a preliminary design plan and determined the core components such as the processing table, external frame, servo motor, and gears.

[0026] Design of functional modules: multiple functional modules are designed, including: Drive system: Power is transmitted through a servo motor, a driving pulley, a driven pulley, and a connecting belt. The combination of Gear 1, Gear 2, and the gear ring ensures precise transmission of rotational force, ensuring stable operation of the grinding equipment on the workbench.

[0027] Sliding mechanism: The sliding mechanism design utilizes a worm gear and worm drive to convert rotational motion into linear motion, which in turn drives the grinding device to slide along the work table. The meshing design of the worm gear and worm ensures smooth and precise motion.

[0028] Grinding Equipment Drive: The combination of the drive motor and the grinding drill ensures the precision and force of the grinding operation. The motor drive and the gear system work together to allow the grinding equipment to effectively adjust the grinding position and adapt to the grinding of copper pipes of different diameters.

[0029] Mechanical structure design: External rack and processing table: The processing table is designed with a highly stable structure, with the bottom legs and support system ensuring the stability of the entire structure. The external rack is designed with load-bearing capacity and transmission efficiency as the goals, and the installation of reinforcing ribs increases the strength of the structure.

[0030] The fixed table and sliding mechanism: The fixed table supports the drive motor and grinding drill bit. The slider and slide rail design ensures smooth movement of the grinding equipment. The fixed plate and spring design enable the grinding equipment to maintain a stable position during processing.

[0031] Detail optimization: Based on the preliminary design, the details of each component were optimized: Gear design: The meshing transmission of gear one and gear two ensures rotation accuracy, and the design of the gear ring improves transmission stability.

[0032] Spring and groove block: The elastic design of the spring ensures that the clamping force of the grinding equipment is appropriate, and the groove block provides a position locking function to prevent the grinding equipment from shifting during operation.

[0033] Legs and base plate: The design of the legs and base plate further enhances the stability of the equipment and avoids vibration during the grinding process.

[0034] After the design of each module was completed, the overall assembly design was carried out to ensure that the various components could connect smoothly and work together. It also ensured that the transmission system, sliding mechanism and grinding equipment could work together while maintaining processing accuracy.

[0035] The present invention has the following beneficial effects: 1. In the present invention, the rotation of the driving pulley causes the fixed rod to rotate synchronously with the gear 1, and then the rotation of the gear 2 is meshed with the gear ring for transmission. The grinding drill bit grinds and rotates in the opposite direction of the copper pipe, and the two-way grinding process of the inner wall of the copper pipe can be carried out synchronously without the need for cumbersome adjustment processes, which can meet the needs of use.

[0036] 2. In the present invention, the rotation of the elliptical block pushes the groove block to move, and the movement of the groove block pulls the spring to stretch. At the same time, the fixed platform and the drive motor installed on the fixed platform move synchronously, and the inner wall of the copper pipe can be polished in a mobile manner, which further increases the smooth consistency after polishing and brings convenience to use.
