Abstract

This invention relates to the field of air conditioner metal parts processing technology, and specifically discloses a tapping device suitable for processing air conditioner metal parts. A driving component is fixedly connected to the top of the base, and a movable frame is fixedly connected to the output end of the driving component. A tapping component is fixedly connected to the middle of the movable frame, and a protective component is fixedly connected to the bottom of the movable frame. A worktable is fixedly connected to the base, and a transmission component is fixedly connected to the inner side of the worktable. Positioning components are slidably connected to both sides of the top of the worktable. This tapping device for processing air conditioner metal parts addresses the issue of weak structural strength in the hollowed-out workpiece. If forcibly clamped and positioned, the clamping force concentrates on the sidewall of the workpiece, easily causing concavity in the sidewall and deformation of the hollowed-out area. The first spring allows the positioning plate to adaptively buffer the clamping force after contacting the workpiece, dispersing pressure and preventing extrusion deformation of the hollowed-out workpiece's dimensions.

Description

Technical Field

[0001] This invention relates to the field of air conditioner metal parts processing technology, specifically a tapping device suitable for processing air conditioner metal parts. Background Technology

[0002] Air conditioning metal components are the core metal parts in an air conditioning unit, playing a crucial role in structural support, heat exchange, pipe connection, and protective fixing. They are primarily made of materials such as copper, aluminum, galvanized steel, stainless steel, and brass, and encompass categories including evaporator and condenser copper tubes, heat dissipation aluminum fins, outdoor unit sheet metal housings, motor brackets, mounting bases, pipe joints, compressor metal housings, and fixing brackets. These components require high dimensional accuracy, thread matching, structural strength, and corrosion resistance, serving as fundamental components to ensure stable air conditioning assembly, efficient heat exchange, and stable operation. Tapping equipment adapted for processing these components can precisely machine standard internal threads from various air conditioning metal blanks such as steel, aluminum, and copper. It can handle batch tapping operations on both thin and thick plates, including air conditioning base plates, brackets, housings, and pipe fittings, controlling thread depth and hole diameter accuracy to avoid deformation during thin plate processing and tap breakage. This significantly improves the consistency, production efficiency, and assembly reliability of air conditioning metal parts thread processing.

[0003] Chinese patent CN222344404U discloses a tapping device for machining parts, including a worktable, a limit block fixedly connected to the top of the worktable, clamping mechanisms on both sides of the limit block, support legs fixedly connected to the bottom of the worktable, a sliding groove on the top of the limit block, a cleaning groove on the top of the worktable, a cleaning mechanism on one side of the limit block, a translation mechanism on the top of the worktable, a tapping mechanism on the top of the translation mechanism, and a protective mechanism on the top of the limit block. A displacement mechanism is provided at the bottom of the movable plate, allowing the tap to move back and forth. Combined with the translation mechanism, the tap can move in all directions. The protective mechanism on the top of the limit block prevents debris from splashing during operation. A cleaning groove is provided on the worktable, and a cleaning mechanism is located inside the limit block. A trapezoidal scraper, driven by a fourth motor, drags the machined debris to the cleaning groove, where the debris falls into a collection box. Although this technical solution can collect and process the chips generated during tapping, its chip collection structure is mostly a fixed structure, which cannot move synchronously with the tap feed and adaptively rise and fall to collect impurities in real time. At the same time, in the existing technology, metal chips and oil stains are very easy to adhere to the surface of the tap during long-term continuous processing. The continuous accumulation of impurities can easily cause problems such as tool squeezing, thread scratching, and tap breakage, thus affecting the machining accuracy of the workpiece.

[0005] This invention provides a tapping device suitable for machining metal parts for air conditioners. It has the following beneficial effects: 1. This tapping equipment is suitable for processing metal parts for air conditioners. The structural strength of the hollow workpiece in the middle is weak. If it is rigidly clamped and positioned, the clamping force is concentrated on the side wall of the workpiece, which is very easy to cause the side wall to be concave and the hollow area to be deformed. The first spring enables the positioning plate to adaptively buffer the clamping force after contacting the workpiece, disperse the pressure, and avoid the hollow workpiece from being squeezed and deformed.

[0006] 2. This tapping equipment, suitable for processing metal parts for air conditioners, addresses the issue of traditional side clamping of thin-walled workpieces, where the clamping force is concentrated on the thin edges of the two sides of the plate, which can easily cause the plate to bend. By using the top positioning roller to press down and limit the clamping, the pressure from both sides is changed to top flexible clamping, reducing the risk of thin plate deformation. The second spring can adaptively extend and retract according to the thickness of the workpiece, and the moving plate automatically rises and falls to fit the top surface of the workpiece, allowing for the application of clamping force to thin-walled parts of different thicknesses.

[0007] 3. This tapping equipment is suitable for processing metal parts for air conditioners. The air conditioner parts include thin-walled sheet metal, thick aluminum die castings, compressor housings and other workpieces of various thicknesses. The telescopic rod, together with the third spring and the bellows, can automatically adapt to the height of the workpiece as the moving frame descends, regardless of the thickness of the workpiece, and lifts and collects debris.

[0008] 4. This tapping equipment is suitable for processing metal parts for air conditioners. The flocculent aluminum chips and flaky iron chips generated during tapping are prone to floating and drifting. The side wall baffle guides the airflow and chips to flow in a directional direction to the feed trough, preventing chips from suspending and accumulating at the corners of the collection shell. When the negative pressure fan stops, the one-way feed valve automatically closes, and the chips and oil already collected in the storage shell will not flow back into the collection shell. The chips are uniformly stored inside the storage shell.

[0009] 5. This tapping equipment, suitable for processing metal parts for air conditioners, relies on strong airflow to clean the inner wall of the collection housing. The cleaning shaft forms a linear guiding constraint on the cleaning frame. Once the airflow suction decreases, the fourth spring drives the cleaning frame to fall back, performing a secondary cleaning operation on the inner wall of the collection housing, thus preventing metal powder from adhering to the inner wall of the collection housing for a long time.

[0010] 6. This tapping equipment is suitable for processing metal parts for air conditioners. Most air conditioner parts are made of aluminum alloy. During tapping, the high temperature can easily cause aluminum chips to melt and stick to the cutting edge of the tap. If not cleaned in time, the thread profile will be damaged during cutting. The wiping roller continuously scrapes off the flocculent aluminum chips, iron powder, and oil stains on the surface of the tap, preventing impurities from adhering to the tap. The wiping roller and the tap are in rolling contact, which has less contact friction compared to the sliding scraping of a hard scraper, avoiding excessive wear on the tap. The spring can automatically adjust the contact distance between the wiping roller and the tap according to the extrusion pressure, so as to make adaptive adjustment of contact cleaning work according to different sizes of taps.

Detailed Implementation

[0013] Please see Figures 1-3 This invention provides a tapping device suitable for machining metal parts for air conditioners, comprising: A worktable 4 is fixedly connected to the base 1. A transmission component 8 is fixedly connected to the inner side of the worktable 4. Positioning components 9 are slidably connected to both sides of the top of the worktable 4. The positioning components 9 on both sides move relative to each other on the worktable 4 through the output end of the transmission component 8. When the workpiece is placed in the middle of the worktable 4, the transmission component 8 is started. The output end of the transmission component 8 drives the two sets of positioning components 9 to move towards each other on the worktable 4 to limit and fix the workpiece. A drive component 2 is fixedly connected to the top of the base 1. A movable frame 3 is fixedly connected to the output end of the drive component 2. A tapping component 6 is fixedly connected to the middle of the movable frame 3. Then, the drive component 2 is started, and the output end of the drive component 2 drives the movable frame 3 to move downward along the base 1, so that the tapping component 6 is aligned with the hole to be processed on the workpiece. The bottom of the movable frame 3 is fixedly connected to a protective component 7. When the tapping component 6 is turned on, the workpiece is tapped. During the process, the protective component 7 collects the metal chips generated during tapping in real time. Example 1, please refer to Figures 4-5 The invention also includes a positioning component 9 and a positioning frame 91 symmetrically slidably connected to the top of the worktable 4. The two positioning frames 91 are driven to move relative to each other on the worktable 4 through the output end of the transmission component 8. After the workpiece is placed in the middle of the worktable 4, the transmission component 8 is activated. The output end of the transmission component 8 drives the two sets of positioning frames 91 to move towards each other on the worktable 4 to position and clamp the workpiece at the center of the worktable 4. The side of the positioning frame 91 is evenly provided with slide rods 92. One end of the slide rod 92 is slidably connected to the positioning frame 91. When clamping a rectangular workpiece of normal height, the positioning frame 91 drives the positioning plate 93 to fit against the workpiece for clamping through the slide rod 92. Furthermore, a first spring 94 is sleeved on the slide rod 92. One end of the first spring 94 is fixedly connected to the positioning frame 91, and the other end of the first spring 94 is fixedly connected to the positioning plate 93. During the clamping process, the first spring 94 sleeved on the slide rod 92 can buffer and squeeze the positioning plate 93 to prevent the hollow workpiece in the middle from being squeezed and deformed due to rigid clamping. It also includes a positioning plate 93 that slides inside the positioning frame 91. The side of the positioning plate 93 is fixedly connected to the end of the slide rod 92 away from the positioning frame 91. The bottom of the positioning plate 93 is evenly provided with a sliding shaft 96 and a positioning shaft 95. The top of the positioning shaft 95 and the sliding shaft 96 are both slidably connected to the inside of the positioning plate 93. The other end of the positioning shaft 95 and the sliding shaft 96 is fixedly connected to a moving plate 97. The inside of the moving plate 97 is rotatably connected with a positioning roller 98. When clamping a thin-walled rectangular workpiece, the edge of the workpiece enters the positioning plate 93, so that the top surface of the workpiece is in contact with the moving plate 97 inside the positioning plate 93. The surface of the moving plate 97 is evenly provided with positioning rollers 98. When the workpiece is pushed in, the rolling contact of the positioning rollers 98 reduces the sliding friction and avoids excessive squeezing force between the workpiece and the top of the workpiece, which may cause the workpiece to be unable to move. A second spring 99 is sleeved on the sliding shaft 96. The moving plate 97 is guided by the top positioning shaft 95 and the sliding shaft 96. With the help of the second spring 99 sleeved on the sliding shaft 96, the positioning roller 98 is driven to complete the limiting positioning from above the workpiece, avoiding clamping the two sides of the workpiece and preventing the thin-walled workpiece from being deformed by pressure. Please see Figures 6-7 The present invention also includes a protective component 7. The driving component in the tapping component 6 drives the tap to rotate in the moving frame 3. At the same time, the driving component 2 drives the moving frame 3 to move down along the base 1, and the tap approaches the workpiece hole to carry out the tapping operation. The negative pressure fan 71, which is fixedly connected to the bottom of the mobile frame 3, and the wiping mechanism 79, which is set at the bottom of the collection housing 76, will drive the negative pressure fan 71 to move down in sync during the downward movement of the mobile frame 3, so that the bottom of the wiping mechanism 79 presses against the top surface of the workpiece. The output end of the negative pressure fan 71 is fixedly connected to a storage shell 72. Telescopic rods 74 are fixedly connected to both sides of the bottom of the storage shell 72. A third spring 75 is sleeved on the telescopic rods 74. It also includes a bellows 73 symmetrically connected to both sides of the bottom of the storage shell 72. A collection shell 76 is fixedly connected to the bottom of the bellows 73. A one-way feed valve is fixedly connected to the top of the bellows 73. As the moving frame 3 continues to feed, the storage shell 72 below the negative pressure fan 71 moves relative to the collection shell 76 above the wiping mechanism 79 through the telescopic rods 74, compressing the third spring 75 on the outside of the telescopic rods 74. At the same time, it compresses the bellows 73 between the storage shell 72 and the collection shell 76, so as to achieve height self-adaptation, adapt to the processing requirements of workpieces of different thicknesses and different depths, and collect the debris generated by tapping simultaneously. The collecting shell 76 has feeding grooves 78 on both sides below the baffle 77. A mesh plate 710 is fixedly connected to the bottom of the inner cavity of the collecting shell 76. When tapping, the negative pressure fan 71 is started, and the airflow generates suction force. The metal chips generated by tapping are sucked into the collecting shell 76 through the feeding grooves 78. The top of the collecting shell 76 is fixedly connected to the bottom of the telescopic rod 74. A baffle 77 is fixedly connected to the side of the collecting shell 76 near the tapping part 6. The baffle 77 on the side wall of the collecting shell 76 guides the debris, allowing the debris to enter the cavity of the collecting shell 76. Under the action of negative pressure suction, the debris passes through the bellows 73 and the one-way feed valve at the upper end of the bellows 73, and enters the storage shell 72 for centralized storage. And a cleaning mechanism 711 that is slidably connected in the inner cavity of the collection housing 76. During the continuous operation of the negative pressure, the built-in cleaning mechanism 711 moves inside the collection housing 76 and automatically wipes the impurities accumulated on the inner wall of the housing. At the same time, the wiping mechanism 79 below continuously adheres to the outer wall of the tap and cleans the chips adhering to the surface of the tap in real time. Please see Figure 8 The present invention also includes a cleaning mechanism 711. The side of the cleaning frame 7111 contacts the inner side of the collection shell 76. The top of the cleaning frame 7111 is uniformly provided with cleaning shafts 7112. The top of the cleaning shaft 7112 is slidably connected to the top of the inner cavity of the collection shell 76. The bottom of the cleaning shaft 7112 is fixedly connected to the top of the cleaning frame 7111. A fourth spring 7113 is sleeved on the cleaning shaft 7112. The negative pressure fan 71 continuously draws air to generate negative pressure suction, which stably sucks in the tapping debris and collects it into the storage shell 72. During operation, the strong airflow can drive the cleaning frame 7111 inside the collection shell 76 to slide upward against the inner wall of the shell for cleaning. While the cleaning frame 7111 moves along the cleaning shaft 7112, it compresses the fourth spring 7113 sleeved on the shaft. The top of the fourth spring 7113 is fixedly connected to the top of the inner cavity of the collection shell 76, and the bottom of the fourth spring 7113 is fixedly connected to the top of the cleaning frame 7111. When the negative pressure wind force weakens, the fourth spring 7113 resets, driving the cleaning frame 7111 to slide down and reset along the cleaning shaft 7112, completing a secondary cleaning of the inner wall of the collection shell 76, removing residual impurities attached to the inner wall of the shell, and preventing debris from accumulating and adhering after long-term operation. Please see Figure 9 The present invention also includes a wiping mechanism 79, the top of the wiping shell 791 is fixedly connected to the bottom of the collecting shell 76, when the moving frame 3 drives the tap to tap the workpiece hole, it simultaneously drives the bottom of the wiping shell 791 to press against the top surface of the workpiece. During the processing, the outer wall of the tap and the wiping roller 794 roll in contact, which can clean the metal debris and oil stains adhering to the surface of the tap in real time. The inner side of the wiping housing 791 is uniformly provided with connecting shells 793. The side of the connecting shell 793 is slidably connected to the inner side of the wiping housing 791. The side of the connecting shell 793 is fixedly connected to the connecting shaft 792. The other end of the connecting shaft 792 is slidably connected to the inner side of the wiping housing 791. A fifth spring 795 is sleeved on the connecting shaft 792. A wiping roller 794 is rotatably connected to the inner side of the connecting shell 793. The wiping roller 794 is located on the side close to the tapping component 6. If there are many impurities attached to the tap and the contact pressure is too large, the wiping roller 794 will drive the connecting shell 793 to slide along the connecting shaft 792 into the wiping housing 791, squeezing the fifth spring 795 sleeved on the connecting shaft 792. The spring buffers and unloads the force to avoid damage to the wiping roller 794 and the tap due to excessive squeezing. Specific workflow: Place the workpiece in the middle of the worktable 4, start the transmission component 8, and the output end of the transmission component 8 drives the two sets of positioning components 9 to move towards each other on the worktable 4 to limit and fix the workpiece. Then the drive unit 2 is started. The output end of the drive unit 2 drives the moving frame 3 to move downward along the base 1, so that the tapping part 6 is aligned with the hole to be processed on the workpiece. The tapping component 6 is activated to tap the workpiece, and the protective component 7 collects the metal chips generated during the tapping process in real time. After the workpiece is placed in the middle of the worktable 4, the transmission component 8 is started. The output end of the transmission component 8 drives the two sets of positioning frames 91 to move towards each other on the worktable 4, thereby positioning and clamping the workpiece at the center of the worktable 4. When clamping a rectangular workpiece of normal height, the positioning frame 91 drives the positioning plate 93 to fit against the workpiece for clamping via the slide rod 92; During the clamping process, the first spring 94 sleeved on the slide bar 92 can buffer and squeeze the positioning plate 93 to prevent the hollow workpiece in the middle from being squeezed and deformed due to rigid clamping; When clamping a thin-walled rectangular workpiece, the edge of the workpiece enters the positioning plate 93, so that the top surface of the workpiece is in contact with the moving plate 97 inside the positioning plate 93. Positioning rollers 98 are evenly arranged on the surface of the moving plate 97. When the workpiece is pushed in, the rolling contact of the positioning rollers 98 reduces sliding friction. The movable plate 97 is guided by the top positioning shaft 95 and the sliding shaft 96. With the help of the second spring 99 sleeved on the sliding shaft 96, it drives the positioning roller 98 to complete the limiting positioning from above the workpiece, avoiding clamping the two sides of the workpiece and preventing the thin-walled workpiece from being deformed by pressure. The driving component in the tapping component 6 drives the tap to rotate in the moving frame 3. At the same time, the driving component 2 drives the moving frame 3 to move down along the base 1, and the tap approaches the workpiece hole to carry out the tapping operation. During the downward movement of the mobile frame 3, the negative pressure fan 71 will move downward in sync, so that the bottom of the wiping mechanism 79 presses against the top surface of the workpiece. As the moving frame 3 continues to feed, the storage shell 72 below the negative pressure fan 71 moves in a telescopic relative motion with the collection shell 76 above the wiping mechanism 79 via the telescopic rod 74, compressing the third spring 75 on the outside of the telescopic rod 74, and at the same time compressing the bellows 73 between the storage shell 72 and the collection shell 76, so as to achieve height self-adaptation, adapt to the processing requirements of workpieces of different thicknesses and different depths, and collect the debris generated by tapping simultaneously. When tapping is performed, the negative pressure fan 71 is started, and the airflow generates an adsorption force. The metal chips generated during tapping are sucked into the collection shell 76 through the feed trough 78. The side wall baffle 77 of the collecting shell 76 guides the debris, allowing the debris to enter the cavity of the collecting shell 76. Under the action of negative pressure suction, the debris passes through the bellows 73 and the one-way feed valve at the upper end of the bellows 73, and enters the storage shell 72 for centralized storage. During continuous negative pressure operation, the built-in cleaning mechanism 711 moves inside the collection housing 76 to automatically wipe away the accumulated impurities on the inner wall of the housing. At the same time, the lower wiping mechanism 79 continuously adheres to the outer wall of the tap to clean the chips adhering to the surface of the tap in real time. The negative pressure fan 71 continuously draws air to generate negative pressure suction, which stably sucks in the tapping debris and collects it into the storage shell 72. During operation, the strong airflow can drive the cleaning rack 7111 inside the collection shell 76 to slide upward against the inner wall of the shell for cleaning. While the cleaning rack 7111 moves along the cleaning shaft 7112, it compresses the fourth spring 7113 sleeved on the shaft. When the negative pressure wind weakens, the fourth spring 7113 resets, causing the cleaning frame 7111 to slide down along the cleaning shaft 7112 to reset, completing a secondary cleaning of the inner wall of the collection shell 76, removing residual impurities attached to the inner wall of the shell, and preventing debris from accumulating and adhering after long-term operation. When the moving frame 3 drives the tap to tap the workpiece hole, it simultaneously drives the bottom of the wiping shell 791 to press against the top surface of the workpiece. During the processing, the outer wall of the tap and the wiping roller 794 roll in contact, which can clean the metal debris and oil stains adhering to the surface of the tap in real time. If the tap has a lot of impurities attached and the contact pressure is too high, the wiping roller 794 will drive the connecting shell 793 to slide along the connecting shaft 792 into the wiping shell 791, squeezing the fifth spring 795 sleeved on the connecting shaft 792. The spring will buffer and relieve the force, preventing the wiping roller 794 and the tap from being damaged due to excessive pressure.
