Description

Technical Field

[0001] The present invention relates to the technical field of metal turning, and more specifically, to an automatic processing device for metal sleeve joints and a processing method thereof. Background Art

[0002] In modern industrial production, metal sleeve joints are widely used in many fields such as aerospace, automotive manufacturing, petrochemical industry, and construction engineering due to their excellent mechanical properties and connection stability, playing a key role in the efficient operation of the entire industrial system. In the production process of metal sleeve joints, turning processing, as the core process, can precisely shape the outer shape of metal sleeve joints and directly determine the quality and performance of the products.

[0003] However, there is an urgent problem to be solved in the existing metal sleeve joint processing technology. During the turning process, due to the high-speed cutting action between the cutting tool and the metal sleeve joint material, a large amount of chips will be generated, as shown in the attached drawings of the specification. Figure 1 These chips are extremely easy to splash into the inside of the metal sleeve joint under the action of centrifugal force and cutting force. When the chips splash slightly, even if the overall structure of the metal sleeve joint is not severely affected, in order to meet the product quality requirements, additional cleaning steps are still required. This not only prolongs the processing cycle, increases the labor and time costs, but also may introduce new impurities or damage the product surface during the cleaning process. When the chips splash severely, they will be embedded in the internal thread grooves and other structures of the metal sleeve joint. The internal thread groove is a key part for the metal sleeve joint to achieve the connection function, with a fine and complex structure. Once the chips enter, it is extremely difficult to clean. Traditional cleaning methods are difficult to completely remove the chips, resulting in an impact on the connection performance of the joint. In this case, it is often necessary to perform secondary processing on the product, which not only further consumes a large amount of raw materials, energy, and processing time, greatly increasing the production cost, but also seriously affects the production efficiency. The splashing of chips also reduces the qualified rate of metal sleeve joint processing and hinders the overall high-quality development of the industry. In view of this, we propose an automatic processing device for metal sleeve joints and a processing method thereof. Summary of the Invention

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0018] 1. The present invention improves the existing metal sleeve joint processing equipment. By arranging a clamping tooling, a lathe, a tool, a three-axis moving and handling mechanism and a right-angle flipping mechanism on the processing table, and by setting a processing mechanism on the right-angle flipping mechanism, a three-jaw chuck is arranged on the processing mechanism, a vertical reciprocating mechanism is arranged inside the processing mechanism, and an air blowing guide is arranged at the bottom end of the processing mechanism. The three-jaw chuck clamps the turned metal sleeve structure. The vertical reciprocating mechanism drives part of the processing mechanism to move vertically. The jet end of the processing mechanism slides along the spiral chute on the spiral part of the air blowing guide. The processing mechanism pumps air and sprays the gas through the jet end to clean the inside of the inner thread groove of the metal sleeve joint specifically. The present invention has the advantages of good cleaning effect, cost reduction, processing cycle shortening and yield rate improvement.

[0019] 2. In the present invention, the driving air pump pumps air. The gas enters the inside of the transition pipe from the air inlet pipe of the dual-state air duct, is transmitted to the air delivery pipe through the transition pipe, is transmitted to the compressed air pipe by the air delivery pipe, and finally is sprayed out along the spiral sliding of the air blowing guide by the movable nozzle. In the present invention, the gas is sprayed out along the spiral sliding of the air blowing guide by the movable nozzle through a specific air path, can penetrate into each part of the inner thread groove, effectively blows out the chips, avoids chip residue, ensures the integrity and cleanliness of the inner thread groove structure of the joint, improves the connection performance of the joint, and thus improves the product quality. Due to the problem of chip cleaning in the prior art, secondary processing is often required, consuming a large amount of resources, adding extra steps, and prolonging the processing time. The present invention synchronously cleans the chips during the processing, avoids secondary processing, reduces the waste of raw materials and energy, reduces the labor cost, effectively controls the production cost, makes the whole processing process more compact and efficient, significantly shortens the processing cycle, and improves the production efficiency.

[0020] 3. In the present invention, a servo motor A is arranged in the accommodating cavity, and a rotating pipe is arranged in the transition pipe. The servo motor A drives the rotating pipe to rotate, and the rotating pipe drives the fitting groove and the movable arc block hinged thereon to rotate. At this time, as Figure 7 and Figure 8As shown, rotation causes one of the movable arc blocks to break free from the restraint of the inner convex arc block. Since one end of the inner convex arc block is hinged to the fitting groove, gravity causes the movable arc block to break away from the fitting groove, blocking the communication path between the intake pipe and the delivery pipe in the transition pipe. As a result, the gas output from the dual-state air passage accumulates and is ejected in a wave-like manner, creating an instant high pressure at the jet end of the movable nozzle. When the movable arc block blocks the gas path, the gas accumulates at the front end of the transition pipe, and the pressure continuously increases. When the movable arc block rotates and breaks free from the restraint of the inner convex arc block, the high-pressure gas is instantaneously ejected from the movable nozzle. Compared with continuous and stable gas jetting, the impact force of this instant high-pressure gas is stronger, and it can more powerfully blow off and remove the chips tightly adhering to the inner thread groove, improving the cleaning effect.

[0021] 4. In the present invention, turning the knob drives the rotating disk to rotate. The rotating disk drives the curve groove to rotate, the curve groove drives the limiting rod, and the limiting rod drives the expansion and contraction rod to move within the guide groove of the fixed disk. When the expansion and contraction rod expands outward, it drives the magnetic block to move outward synchronously until it fits against the inner wall of the rotating pipe. The magnetic force of the magnetic block adsorbs the movable arc block made of metal material onto the outer wall of the rotating pipe, causing the movable arc blocks to fit together. At this time, the communication path between the intake pipe and the delivery pipe in the transition pipe is unblocked, forming a continuous gas output, cleaning the chips in a relatively gentle manner, avoiding excessive impact damage to the joint, and achieving flexible adjustment of the cleaning intensity.

[0022] 5. The present invention can be adapted to metal sleeve joints of different specifications and materials. Due to differences in their processing techniques and chip characteristics, for some thin-walled or high-precision joints, continuous gas output can meet the requirements of fine cleaning, ensuring that the structural integrity of the joint is not affected while cleaning the chips; for thick-walled joints with a large amount of chips, wave-like gas output can quickly clean a large number of chips with a powerful impact force. This adjustable gas output mode enables the device to be widely applied to various processing scenarios, improving the versatility and applicability of the device. BRIEF DESCRIPTION OF THE DRAWINGS

The processing mechanism 7 pumps air and sprays the gas through the air jet end to perform targeted cleaning on the inside of the groove body of the internal thread groove of the metal sleeve joint.

[0053] The present invention improves the existing metal sleeve joint processing equipment. By arranging a clamping tooling 2, a lathe 3, a cutting tool 4, a three-axis moving and handling mechanism 5 and a right-angle flipping mechanism 6 on a processing table 1, and by setting a processing mechanism 7 on the right-angle flipping mechanism 6, a three-jaw chuck 10 is provided on the processing mechanism 7, a vertical reciprocating mechanism 8 is arranged inside the processing mechanism 7, and an air-blowing guide 9 is provided at the bottom end of the processing mechanism 7. The three-jaw chuck 10 clamps the turned metal sleeve structure. The processing mechanism 7 is driven by the vertical reciprocating mechanism 8 to move vertically in part. The jet end of the processing mechanism 7 slides in a spiral chute 902 on a spiral member 901 of the air-blowing guide 9.

[0054] In an embodiment of the present invention, the processing mechanism 7 includes a bearing assembly 701, a dual-state air passage 702, a rotating assembly 703, a magnetic control assembly 704, a compressed air pipe 705 and a movable spray pipe 706.

[0055] The present invention realizes efficient cleaning of the internal thread groove of the metal sleeve joint and precise adjustment of the jet angle by setting a bearing assembly 701 on the right-angle flipping mechanism 6, arranging a dual-state air passage 702, a rotating assembly 703 and a magnetic control assembly 704 inside the bearing assembly 701, and setting a compressed air pipe 705 and a movable spray pipe 706 at the bottom end of the bearing assembly 701, so as to ensure the processing quality.

[0056] In an embodiment of the present invention, the bearing assembly 701 includes a bearing block 7011, a receiving cavity 7012, an air pump 7013 and a bottom pipe 7014. The bearing block 7011 is connected to the right-angle flipping mechanism 6, the receiving cavity 7012 is opened inside the bearing block 7011, the air pump 7013 is arranged on the outer wall of the bearing block 7011, the bottom pipe 7014 is connected to the bottom end of the bearing block 7011, the dual-state air passage 702 is arranged in the receiving cavity 7012, the compressed air pipe 705 is slidably inserted into the bottom pipe 7014, the vertical reciprocating mechanism 8 is arranged inside the bottom pipe 7014, and the air-blowing guide 9 is fixedly connected to the bottom end of the bottom pipe 7014.

[0057] In an embodiment of the present invention, the bistate air duct 702 includes an air inlet pipe 7021, a transition pipe 7022, an air delivery pipe 7023, and an inner convex arc block 7024. One end of the air inlet pipe 7021 is connected to the output end of the air pump 7013, and the other end of the air inlet pipe 7021 is inserted into the bearing block 7011 and extends into the accommodation cavity 7012. The transition pipe 7022 is connected to the end of the air inlet pipe 7021 away from the air pump 7013. The inner convex arc block 7024 is arranged on the inner wall of the transition pipe 7022. The air delivery pipe 7023 is fixedly inserted at a position of the transition pipe 7022 close to the inner convex arc block 7024. The rotating assembly 703 is rotatably inserted into the interior of the transition pipe 7022.

[0058] In the present invention, by driving the air pump 7013 to pump air, the gas enters the interior of the transition pipe 7022 from the air inlet pipe 7021 of the bistate air duct 702, is transmitted to the air delivery pipe 7023 through the transition pipe 7022, is transmitted to the compression air pipe 705 by the air delivery pipe 7023, and finally is ejected spirally along the air blowing guide 9 by the movable nozzle 706. In the present invention, the gas is ejected spirally along the air blowing guide from the movable nozzle through a specific air path, can penetrate into each part of the internal thread groove, effectively blow out the chips, avoid chip residue, ensure the integrity and cleanliness of the internal thread groove structure of the joint, improve the connection performance of the joint, and thus improve the product quality. Due to the problem of chip cleaning in the prior art, secondary processing is often required, consuming a large amount of resources.

Traditional processing adds additional steps due to chip cleaning and prolongs the processing time. The present invention completes the cleaning while processing, reduces the waiting time for cleaning and secondary processing, makes the whole processing process more compact and efficient, significantly shortens the processing cycle, and improves the production efficiency.

[0059] In an embodiment of the present invention, the rotating assembly 703 includes a servo motor A 7031, a rotating pipe 7032, a fitting groove 7033, and a movable arc block 7034. The servo motor A 7031 is arranged in the accommodation cavity 7012. One end of the rotating pipe 7032 is connected to the output end of the servo motor A 7031, and the other end of the rotating pipe 7032 is rotatably inserted into the transition pipe 7022. The fitting groove 7033 is annularly and equidistantly opened on the outer wall of the rotating pipe 7032. One end of the movable arc block 7034 is hinged to the fitting groove 7033 and is adapted to the size of the fitting groove 7033. The magnetic control assembly 704 is arranged on the rotating pipe 7032.

[0060] In the present invention, by arranging the servo motor A 7031 in the accommodation cavity 7012 and arranging the rotating pipe 7032 in the transition pipe 7022, the rotating pipe 7032 is driven to rotate by the servo motor A 7031. The rotating pipe 7032 drives the fitting groove 7033 and the movable arc block 7034 hinged thereon to rotate. At this time, as Figure 7 and Figure 8As shown, rotation causes one of the movable arc blocks 7034 to break away from the restriction of the inner convex arc block 7024. Since one end of the inner convex arc block 7024 is hinged on the fitting groove 7033, gravity causes the movable arc block 7034 to break away from the fitting groove 7033, blocking the communication path between the intake pipe 7021 and the delivery pipe 7023 in the transition pipe 7022. The gas output by the dual-state air duct 702 accumulates and is ejected in a banded manner, creating an instantaneous high pressure at the jet end of the movable nozzle 706. When the movable arc block 7034 blocks the air path, the gas accumulates at the front end of the transition pipe 7022, and the pressure continuously increases. When the movable arc block 7034 rotates and breaks away from the restriction of the inner convex arc block 7024, the high-pressure gas is instantaneously ejected from the movable nozzle 706. Compared with continuous and stable jetting, the impact force of this instantaneous high-pressure gas is stronger, and it can more powerfully blow off and remove the chips tightly attached in the internal thread groove, improving the cleaning effect.

[0061] In an embodiment of the present invention, the magnetic control assembly 704 includes a fixed disk 7041, a rotating disk 7042, a telescopic rod 7043, a magnetic block 7044, a guide groove 7045, a curve groove 7046, a limiting rod 7047, and a knob 7048. The fixed disk 7041 is fixedly arranged on the inner wall of the bearing block 7011. The rotating disk 7042 is rotatably inserted into the inner wall of the fixed disk 7041. The guide groove 7045 is annularly and equidistantly arranged on the fixed disk 7041. The telescopic rod 7043 is movably inserted into the guide groove 7045. The magnetic block 7044 is fixedly connected to one end of the telescopic rod 7043 away from the guide groove 7045. The curve groove 7046 is annularly and equidistantly arranged on the rotating disk 7042. One end of the limiting rod 7047 is fixedly connected to one end of the telescopic rod 7043 away from the magnetic block 7044. The other end of the limiting rod 7047 is movably inserted into the curve groove 7046. The knob 7048 is rotatably arranged on the outer wall of the bearing block 7011 and is connected to the rotating disk 7042. The magnetic block 7044 is arc-shaped and fits and mates with the rotating pipe 7032.

[0062] In the present invention, by twisting the knob 7048, the rotating disk 7042 is driven to rotate. The rotating disk 7042 drives the curve groove 7046 to rotate. The curve groove 7046 drives the limiting rod 7047, and the limiting rod 7047 drives the telescopic rod 7043 to move within the guide groove 7045 of the fixed disk 7041. When the telescopic rod 7043 expands outwards, it drives the magnetic block 7044 to move outwards synchronously until it fits against the inner wall of the rotating pipe 7032. The magnetic force of the magnetic block 7044 adsorbs the movable arc block 7034 made of a metal material on the outer wall of the rotating pipe 7032, making the movable arc blocks 7034 all fit. At this time, the communication path between the intake pipe 7021 and the delivery pipe 7023 in the transition pipe 7022 is not blocked, forming a continuous gas output, cleaning the chips in a relatively gentle manner, avoiding excessive impact damage to the joint, and realizing flexible adjustment of the cleaning intensity.

[0063] When the telescopic rod 7043 retracts, it drives the magnetic block 7044 to move inward synchronously until it completely disengages from the inner wall of the rotating tube 7032. The magnetic force of the magnetic block 7044 weakens, causing the movable arc block 7034 to return to its movable state, forming a wave-like gas output. The high-pressure gas ejected instantaneously can generate a large impact force, effectively removing stubborn chips.

[0064] The present invention can be adapted to metal sleeve joints of different specifications and materials. Due to differences in their processing techniques and chip characteristics, for some thin-walled or high-precision joints, continuous gas output can meet the fine cleaning requirements, ensuring that the structural integrity of the joints is not affected while cleaning the chips; for thick-walled joints with a large amount of chips, the wave-like gas output can quickly clean a large number of chips with its powerful impact force. This adjustable gas output mode enables the device to be widely applied to various processing scenarios, improving the versatility and applicability of the device.

[0068] In the present invention, the gas output from the dual-state air duct 702 is transmitted to the tapered tube end 7052 through the straight tube section 7051 of the compressed air pipe 705, and then transmitted from the tapered tube end 7052 to the movable nozzle 706 for ejection.

The ejection section 7063 of the movable nozzle 706 is slidably inserted into the spiral chute 902 of the spiral member 901 of the air blowing guide member 9. Since the rotation groove 7064 is provided on the ejection section 7063, and the pulley 7065 is sleeved on the rotation groove 7064, and since the rotation section 7061 is rotatably connected to the tapered tube end 7052, the gas spirally descends and ejects from the ejection section 7063 along the spiral chute 902, and can closely fit the spiral structure of the internal thread groove of the metal sleeve joint, and perform all-round and dead-angle-free cleaning on the inside of the groove body.

[0069] Working principle: This embodiment provides a processing method for an automatic processing equipment of a metal sleeve joint, including the following steps:

[0070] S1. Fixing operation;

[0071] The metal sleeve joint to be processed is transported to the clamping tooling 2 by the three-axis moving and handling mechanism 5 to complete the fixing;

[0072] S2. Turning processing operation;

[0073] The clamping tooling 2 rotates, the lathe 3 is started, and the tool 4 starts to perform turning processing on the metal sleeve joint. During the processing, chips will be generated, and some chips may splash into the inside of the metal sleeve joint;

[0074] S3. State adjustment operation;

[0075] According to the type of the metal sleeve joint to be processed, select the gas output state;

[0076] S3.1. When dealing with a thin-walled metal sleeve joint or when the chip adhesion is not high, twist the knob 7048 to drive the rotating disk 7042 to rotate. The rotating disk 7042 drives the curved groove 7046 to rotate. The curved groove 7046 drives the limiting rod 7047, and the limiting rod 7047 drives the expansion and contraction rod 7043 to move within the guide groove 7045 of the fixed disk 7041. When the expansion and contraction rod 7043 expands outwards, it drives the magnet block 7044 to move outwards synchronously until it fits against the inner wall of the rotating pipe 7032. The magnetic force of the magnet block 7044 adsorbs the movable arc block 7034 made of metal material on the outer wall of the rotating pipe 7032, so that the movable arc blocks 7034 all fit. At this time, there is no blockage in the communication path between the intake pipe 7021 and the air delivery pipe 7023 in the transition pipe 7022, forming a continuous gas output to clean the chips in a relatively gentle manner.

[0077] S3.2. When dealing with stubbornly attached chips, twist the knob 7048 to drive the rotating disk 7042 to rotate. The rotating disk 7042 drives the curved groove 7046 to rotate. The curved groove 7046 drives the limiting rod 7047, and the limiting rod 7047 drives the expansion and contraction rod 7043 to move within the guide groove 7045 of the fixed disk 7041. When the expansion and contraction rod 7043 contracts inwards, it drives the magnet block 7044 to move inwards synchronously until it completely disengages from the inner wall of the rotating pipe 7032. The magnetic force of the magnet block 7044 weakens, making the movable arc block 7034 return to the movable state. At this time, drive the rotating pipe 7032 to rotate through the servo motor A7031. The rotating pipe 7032 drives the fitting groove 7033 and the movable arc block 7034 hinged thereon to rotate. The rotation will cause one of the movable arc blocks 7034 to break away from the restriction of the inner convex arc block 7024. Since one end of the inner convex arc block 7024 is hinged on the fitting groove 7033, gravity causes the movable arc block 7034 to break away from the fitting groove 7033, blocking the communication path between the intake pipe 7021 and the air delivery pipe 7023 in the transition pipe 7022, so that the gas output by the dual-state air duct 702 accumulates and sprays in a wave-like manner.

[0078] S4. Sleeve processing operation;

[0079] By driving the air pump 7013 to pump air, gas enters the interior of the transition pipe 7022 from the intake pipe 7021 of the dual-state air duct 702, is transmitted to the air delivery pipe 7023 through the transition pipe 7022, is transmitted to the compressed air pipe 705 by the air delivery pipe 7023, is transmitted to the conical pipe end 7052 through the straight pipe section 7051 of the compressed air pipe 705, and then is ejected from the movable nozzle 706 by the conical pipe end 7052. When it is necessary to process the internal thread groove of the metal sleeve joint, first drive the servo motor B801 to drive the reciprocating lead screw 802 to rotate. The reciprocating lead screw 802 drives the rolling sleeve 803 to move. Since the collar 805 is fixedly connected to the rolling sleeve 803 and the compressed air pipe 705, the compressed air pipe 705 is pressed down. The compressed air pipe 705 drives the movable nozzle 706 to press down. The ejection section 7063 of the movable nozzle 706 is slidably inserted into the spiral chute 902 of the spiral member 901 of the air blowing guide member 9. Since the rotation groove 7064 is provided on the ejection section 7063, a pulley 7065 is sleeved on the rotation groove 7064. And since the rotation section 7061 is rotatably connected to the conical pipe end 7052, the gas spirally descends and ejects from the ejection section 7063 along the spiral chute 902, which can closely fit the spiral structure of the internal thread groove of the metal sleeve joint and perform all-round and dead-angle-free cleaning of the inside of the groove body;

[0080] S5. Discharging operation;

[0081] After the cleaning is completed, the three-axis moving and handling mechanism 5 transports the processed metal sleeve joints to the tray and stacks them evenly.

Those of ordinary skill in the art can easily understand the spirit of the present invention based on the above embodiments and make different extensions and changes.
