Description

Technical Field

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

[0002] In modern industrial production, metal sleeve joints are widely used in aerospace, automobile manufacturing, petrochemical, construction engineering and many other fields 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 as the core process can accurately shape the appearance of metal sleeve joints, which directly determines the quality and performance of the product. However, the existing metal sleeve joint processing technology has a problem that needs to be solved urgently. During the turning process, due to the high-speed cutting action of the tool and the metal sleeve joint material, a large amount of chips will be generated, as shown in the attached manual. Figure 1 As shown. Under the action of centrifugal force and cutting force, these chips are very easy to splash into the inside of the metal sleeve joint. When the chips splash slightly, even if the overall structure of the metal sleeve joint is not seriously affected, in order to meet the product quality requirements, additional cleaning steps are still required. This not only prolongs the processing cycle, increases manpower and time costs, but may also introduce new impurities or damage the product surface during the cleaning process. When the chips splash heavily, they will be embedded in the internal thread groove and other structures of the metal sleeve joint. The internal thread groove is the key part for the metal sleeve joint to realize the connection function. The structure is delicate and complex. Once the chips enter, it is extremely difficult to clean. Traditional cleaning methods are difficult to completely remove the chips, which affects the connection performance of the joint. In this case, the product is often required to be processed secondary, which not only further consumes a large amount of raw materials, energy and processing time, greatly increases production costs, but also seriously affects production efficiency. The splashing of chips also reduces the yield rate of metal sleeve joint processing, hindering the overall high-quality development of the industry. In view of this, we propose an automatic processing equipment and processing method for metal sleeve joints. Summary of the invention

[0013] Compared with the prior art, the present invention has the following beneficial effects: 1. The present invention improves the existing metal sleeve joint processing equipment by arranging a clamping tool, a lathe, a tool, a three-axis mobile conveying mechanism and a right-angle flip mechanism on a processing table, and by setting a processing mechanism on the right-angle flip mechanism. The processing mechanism is provided with a three-jaw chuck, a vertical reciprocating mechanism is provided inside the processing mechanism, and an air blowing guide is provided at the bottom of the processing mechanism. The three-jaw chuck clamps the turned metal sleeve structure, and the processing mechanism is driven to move vertically by the vertical reciprocating mechanism. The jet end of the processing mechanism slides in the spiral groove on the spiral part of the air blowing guide, and the processing mechanism pumps air to eject the gas through the jet end, so as to clean the inside of the internal thread groove of the metal sleeve joint. The present invention has the advantages of good cleaning effect, reduced cost, shortened processing cycle and improved yield rate.

[0014] 2. In the present invention, the air pump is driven to pump air, and the gas enters the interior of the transition pipe from the air inlet pipe of the dual-state airway, 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 ejected by the movable nozzle along the spiral sliding of the air blowing guide. In the present invention, the gas is ejected from the movable nozzle along the spiral sliding of the air blowing guide through a specific air path, which can penetrate into various parts 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 product quality. Since the prior art often requires secondary processing due to the difficulty of chip cleaning, consumes a lot of resources, adds extra steps, and prolongs the processing time, the present invention cleans the chips synchronously during the processing process, avoids secondary processing, reduces the waste of raw materials and energy, reduces labor costs, effectively controls production costs, makes the entire processing flow more compact and efficient, significantly shortens the processing cycle, and improves production efficiency.

[0015] 3. In the present invention, a servo motor A is arranged in the accommodating cavity, a rotating tube is arranged in the transition tube, and the rotating tube is driven to rotate by the servo motor A, and the rotating tube drives the fitting groove and the movable arc block hinged thereon to rotate. Figure 7 and Figure 8As shown, the rotation will cause one of the movable arc blocks to break away from the restriction of the inner convex arc block. Since one end of the inner convex arc block is hinged on the fitting groove, gravity causes the movable arc block to break away from the fitting groove, thereby blocking the connecting path between the air inlet pipe and the air delivery pipe in the transition pipe, so that the gas output from the dual-state airway is accumulated and ejected in a band-like manner, resulting in instantaneous 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 continues to increase. When the movable arc block rotates to break away from the restriction of the inner convex arc block, the high-pressure gas is instantly ejected from the movable nozzle. Compared with continuous and stable jetting, this instantaneous high-pressure gas has a stronger impact force and can more effectively blow off and remove the chips tightly attached to the internal thread groove, thereby improving the cleaning effect.

[0016] 4. In the present invention, the rotating disk is driven to rotate by twisting the knob, the rotating disk drives the curved groove to rotate, the curved groove drives the limit rod, the limit rod drives the expansion and contraction rod to move in the guide groove of the fixed disk, and when the expansion and contraction rod expands outward, it drives the magnetic block to move outward synchronously until it fits the inner wall of the rotating tube. The magnetic force of the magnetic block adsorbs the movable arc block made of metal on the outer wall of the rotating tube, so that the movable arc blocks are all fitted. At this time, the connecting path between the air inlet pipe and the air delivery pipe in the transition pipe is not blocked, forming a continuous gas output, cleaning the chips in a relatively gentle way, avoiding excessive impact and damage to the joint, and realizing flexible adjustment of the cleaning intensity.

[0017] 5. The present invention can be adapted to metal sleeve joints of different specifications and materials. Due to differences in their processing technology and chip characteristics, for some thin-walled joints or joints with high precision requirements, continuous gas output can meet the needs of fine cleaning, ensuring that the structural integrity of the joint is not affected while cleaning the chips; for joints with thick walls and more chips, band-type gas output can quickly clean a large amount of chips with its powerful impact force. This adjustable gas output mode enables the equipment to be widely used in a variety of processing scenarios, improving the versatility and applicability of the equipment.

An air blowing guide 9 is provided at the bottom of the processing mechanism 7.

[0024] In an embodiment of the present invention, the processing mechanism 7 includes a bearing assembly 701, a two-state airway 702, a rotating assembly 703, a magnetic control assembly 704, a compressed air pipe 705 and a movable nozzle 706. The bearing assembly 701 is arranged on the right-angle flip mechanism 6, the two-state airway 702 is arranged on the bearing assembly 701, the rotating assembly 703 is arranged inside the bearing assembly 701, the magnetic control assembly 704 is arranged inside the rotating assembly 703, the compressed air pipe 705 is fixedly connected to the bearing assembly 701 and is communicated with the two-state airway 702, one end of the movable nozzle 706 is connected to the compressed air pipe 705 and is communicated with the compressed air pipe 705, the other end of the movable nozzle 706 is slidably inserted into the spiral slide groove 902, the moving end of the vertical reciprocating mechanism 8 is fixedly sleeved on the compressed air pipe 705, and the three-jaw chuck 10 is arranged on the bearing assembly 701.

[0025] The present invention arranges a bearing assembly 701 on a right-angle flip mechanism 6, arranges a dual-state airway 702, a rotating assembly 703 and a magnetic control assembly 704 inside the bearing assembly 701, and arranges a compressed air pipe 705 and a movable nozzle 706 at the bottom end of the bearing assembly 701, so as to achieve efficient cleaning of the internal thread groove of the metal sleeve joint and precise adjustment of the jet angle, thereby ensuring the processing quality.

[0026] In an embodiment of the present invention, the supporting assembly 701 includes a supporting block 7011, a accommodating chamber 7012, an air pump 7013 and a bottom tube 7014, the supporting block 7011 is connected to the right-angle flip mechanism 6, the accommodating chamber 7012 is opened inside the supporting block 7011, the air pump 7013 is arranged on the outer wall of the supporting block 7011, the bottom tube 7014 is connected to the bottom end of the supporting block 7011, the two-state air channel 702 is arranged in the accommodating chamber 7012, the compressed air pipe 705 is movably inserted in the bottom tube 7014, the vertical reciprocating mechanism 8 is arranged inside the bottom tube 7014, and the air blowing guide 9 is fixedly connected to the bottom end of the bottom tube 7014.

[0027] In an embodiment of the present invention, the dual-state air duct 702 includes an air intake pipe 7021, a transition pipe 7022, an air delivery pipe 7023 and an inner convex arc block 7024, one end of the air intake pipe 7021 is connected to the output end of the air pump 7013, the other end of the air intake pipe 7021 is inserted on the supporting block 7011 and extends into the accommodating cavity 7012, the transition pipe 7022 is connected to the end of the air intake 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 in the transition pipe 7022 near the inner convex arc block 7024, and the rotating component 703 is rotatably inserted into the transition pipe 7022.

[0028] In the present invention, the air pump 7013 is driven to pump air, and the gas enters the interior of the transition pipe 7022 from the air inlet pipe 7021 of the dual-state airway 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, and finally is ejected by the movable nozzle 706 along the air blowing guide 9 by spiral sliding. In the present invention, the gas is ejected from the movable nozzle along the air blowing guide by spiral sliding through a specific air path, which can penetrate into various parts 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 product quality. The prior art often requires secondary processing due to the difficulty of chip cleaning, which consumes a lot of resources. The present invention cleans the chips synchronously during the processing process, avoids secondary processing, reduces the waste of raw materials and energy, reduces labor costs, and effectively controls production costs. Traditional processing adds extra steps due to chip cleaning, which prolongs the processing time.

[0029] In an embodiment of the present invention, the rotating component 703 includes a servo motor A7031, a rotating tube 7032, a mating groove 7033 and a movable arc block 7034. The servo motor A7031 is arranged in the accommodating cavity 7012, one end of the rotating tube 7032 is connected to the output end of the servo motor A7031, and the other end of the rotating tube 7032 is rotatably inserted on the transition tube 7022. The mating grooves 7033 are arranged in a circular shape and at equal intervals on the outer wall of the rotating tube 7032. One end of the movable arc block 7034 is hingedly connected to the mating groove 7033 and is adapted to the size of the mating groove 7033. The magnetic control component 704 is arranged on the rotating tube 7032.

[0030] In the present invention, a servo motor A7031 is arranged in the accommodating chamber 7012, and a rotating tube 7032 is arranged in the transition tube 7022. The servo motor A7031 drives the rotating tube 7032 to rotate, and the rotating tube 7032 drives the fitting groove 7033 and the movable arc block 7034 hinged thereon to rotate. Figure 7 and Figure 8As shown, 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, so that the connecting path between the air inlet pipe 7021 and the air delivery pipe 7023 in the transition pipe 7022 is blocked, so that the gas output by the two-state airway 702 is accumulated and ejected in a band-like manner, so that an instantaneous high pressure is formed at the jet end of the movable nozzle 706. When the movable arc block 7034 blocks the gas path, the gas accumulates at the front end of the transition pipe 7022, and the pressure continues to increase. When the movable arc block 7034 rotates to break away from the restriction of the inner convex arc block 7024, the high-pressure gas is instantly ejected from the movable nozzle 706. Compared with continuous and stable jetting, this instantaneous high-pressure gas has a stronger impact force and can more effectively blow off and remove the chips tightly attached to the internal thread groove, thereby improving the cleaning effect.

[0031] In the embodiment of the present invention, the magnetic control assembly 704 includes a fixed disk 7041, a rotating disk 7042, an expansion rod 7043, a magnetic block 7044, a guide groove 7045, a curved groove 7046, a limit 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 on the inner wall of the fixed disk 7041, the guide groove 7045 is annularly arranged on the fixed disk 7041 at equal intervals, and the expansion rod 7043 is movably inserted in the guide groove 7045. On the top, the magnetic block 7044 is fixedly connected to the end of the expansion and contraction rod 7043 away from the guide groove 7045, the curved grooves 7046 are arranged in a ring shape with equal intervals on the rotating disk 7042, one end of the limit rod 7047 is fixedly connected to the end of the expansion and contraction rod 7043 away from the magnetic block 7044, and the other end of the limit rod 7047 is movably inserted in the curved groove 7046, the knob 7048 is rotatably arranged on the outer wall of the supporting block 7011 and connected to the rotating disk 7042, and the magnetic block 7044 is arc-shaped and fits closely with the rotating tube 7032.

[0032] In the present invention, the rotating disk 7042 is driven to rotate by twisting the knob 7048, and the rotating disk 7042 drives the curved groove 7046 to rotate, and the curved groove 7046 drives the limit rod 7047, and the limit rod 7047 drives the expansion and contraction rod 7043 to move in the guide groove 7045 of the fixed disk 7041. When the expansion and contraction rod 7043 expands outward, it drives the magnetic block 7044 to move outward synchronously until it fits the inner wall of the rotating tube 7032. The magnetic force of the magnetic block 7044 adsorbs the movable arc block 7034 made of metal on the outer wall of the rotating tube 7032, so that the movable arc block 7034 is all fitted. At this time, the communication path between the air inlet pipe 7021 and the air delivery pipe 7023 in the transition pipe 7022 is not blocked, forming a continuous gas output, and cleaning the chips in a relatively gentle way to avoid excessive impact damage to the joint, and realize flexible adjustment of the cleaning intensity.

[0033] When the expansion and contraction rod 7043 retracts, it drives the magnetic block 7044 to move inward synchronously until it is completely separated from the inner wall of the rotating tube 7032. The magnetic force of the magnetic block 7044 weakens, allowing the movable arc block 7034 to resume its activity, forming a band-type gas output. The high-pressure gas ejected instantly can generate a large impact force, effectively removing stubborn chips.

[0034] The present invention can be adapted to metal sleeve joints of different specifications and materials. Due to differences in their processing technology and chip characteristics, for some thin-walled joints or joints with high precision requirements, continuous gas output can meet the needs of fine cleaning, ensuring that the structural integrity of the joint is not affected while cleaning the chips; for joints with thick walls and more chips, band-type gas output can quickly clean a large amount of chips with its powerful impact force. This adjustable gas output mode enables the equipment to be widely used in a variety of processing scenarios, thereby improving the versatility and applicability of the equipment.

[0035] As another embodiment of the present invention, the compressed air pipe 705 includes a straight pipe section 7051 and a conical pipe end 7052. The straight pipe section 7051 is movably inserted on the bottom pipe 7014 and is connected to the air supply pipe 7023. The conical pipe end 7052 is fixedly connected to the bottom end of the straight pipe section 7051.
