Description

Technical Field

[0001] The present invention relates to the technical field of tapping processing of steel bar sleeves, and specifically relates to a two-way tapping device for steel bar sleeves. Background Technique

[0002] A steel bar sleeve, also known as a steel bar joint, is a connecting piece used to connect steel bars and having an internal thread corresponding to the thread of the threaded end. Its function is to tightly connect two steel bars together, ensuring the integrity and stability of the steel bars, enabling the steel bars to better transmit and disperse forces, improving the seismic resistance of buildings, and at the same time facilitating construction, saving construction time and labor costs. Prestressed high-strength precision rolled threaded steel bars are screwed with connectors with internal threads at any cross-section, which can be used for connection and tensioning. Axial cold extrusion steel bar connection sets a connection sleeve in the axial direction of two coaxial steel bars and uses a connection tool to apply pressure to the connection sleeve in the axial direction to compress the connection sleeve to achieve the equal-strength connection of steel bars. After the steel bar sleeve is drilled, tapping treatment is required;

[0003] In the tapping processing of steel bar sleeves, there will be a phenomenon of two-way tapping processing, that is, tapping processing is carried out on both ends of the steel bar sleeve respectively. When the existing tapping processing equipment needs to carry out two-way tapping processing on the steel bar sleeve, it is necessary for workers to take down the steel bar sleeve and turn it around, which is time-consuming and laborious and has potential safety hazards. Therefore, we propose a two-way tapping device for steel bar sleeves. Summary of the Invention

[0004] To solve the above technical problems, the present invention provides a two-way tapping device for steel bar sleeves, including a concave frame. A push rod motor is fixedly connected to the top of the inner wall of the concave frame. The driving shaft of the push rod motor is fixedly connected to a pressing block. A tapping machine is fixedly connected to one side of the inner wall of the concave frame. A collection box is fixedly connected to the bottom of the concave frame. A turning mechanism is fixedly connected to the inner wall of the collection box. A bottom support block is fixedly connected to the top of the turning mechanism. An electric slide rail is fixedly connected to the inner wall of the collection box. A peeling mechanism is slidably connected to the bottom of the electric slide rail. A cleaning mechanism is fixedly connected to the inner wall of the collection box. One end of the cleaning mechanism is fixedly connected to a servo motor;

[0005] The rotation mechanism includes an inner connecting long plate, and a driving motor is fixedly connected to the bottom of the inner connecting long plate. The driving shaft of the driving motor penetrates through the inner connecting long plate and is fixedly connected to a top connecting rod. By rotating the top connecting rod, the steel bar sleeve at the top is driven to rotate to change the direction to achieve two-way tapping processing, preventing the need for manual removal and rotation of the steel bar sleeve when the existing tapping processing equipment needs to perform two-way tapping processing on the steel bar sleeve, which is time-consuming and laborious and has potential safety hazards. A long scraping rod is fixedly connected to the outer side of the top connecting rod. When the long scraping rod rotates, it scrapes and cleans the iron filings on the top surface of the inner connecting long plate, preventing a large amount of iron filings from falling and accumulating on the inner connecting long plate after the equipment has been tapping for a long time, making it difficult to be uniformly collected and processed;

[0006] There are two electric slide rails, and the two electric slide rails are distributed on the inner wall of the collection box. The output end of the servo motor is fixedly connected to one side of the collection box. The outer side of the inner connecting long plate is fixedly connected to the inner wall of the collection box. The top of the top connecting rod is fixedly connected to the bottom of the bottom support block;

[0007] A chip discharge long hole is opened on one side of the collection box away from the servo motor. A filtrate plate is fixedly connected to the part of the inner wall of the collection box at the bottom of the chip discharge long hole. A high-pressure water pump is communicated with one side of the collection box close to the servo motor. The water outlet of the high-pressure water pump is communicated with a concave connecting pipe;

[0008] The top of the filtrate plate is slidably connected to the bottom of the cleaning mechanism. The end of the concave connecting pipe away from the high-pressure water pump penetrates through the concave frame and is fixedly connected to the concave frame;

[0009] A bottom-mounted housing is fixedly connected to the bottom of the inner connecting long plate. A heat dissipation bottom hole is opened at the bottom of the bottom-mounted housing. By sleeving the driving motor with the bottom-mounted housing for wrapping and protection and opening the heat dissipation bottom hole at the bottom of the bottom-mounted housing for heat dissipation, it is prevented that the iron filings that are easily attached and dropped on the driving motor placed at the bottom of the inner connecting long plate and the surrounding is surrounded and covered, affecting the heat dissipation efficiency. An arc-shaped block is fixedly connected to the outer side of the inner connecting long plate. An arc-shaped sliding hole is opened at the top of the arc-shaped block. A cross-shaped slider is slidably connected to the inner wall of the arc-shaped sliding hole. By setting the arc-shaped sliding hole and the cross-shaped slider on the outer side of the inner connecting long plate to perform a blocking and limiting correction on the long scraping rod, it is prevented that when the bottom support block driven by the driving motor rotates to change the direction, it is difficult to rotate to a position flush with the tap by visual observation, resulting in errors in the tapping processing;

[0010] There are multiple heat dissipation bottom holes, and the multiple heat dissipation bottom holes are distributed at the bottom of the bottom-mounted housing. There are two arc-shaped blocks, and the two arc-shaped blocks are distributed on the outer side of the inner connecting long plate.

[0011] Furthermore, the peeling mechanism includes a concave connecting plate. Both sides of the inner wall of the concave connecting plate are rotatably connected to an inner long rod through a rotating bolt. One end of the inner long rod is fixedly connected to a transmission wheel. A rigid arc brush is fixedly connected to the outer side of the inner long rod. When the rigid arc brush rotates with the inner long rod, it performs a lifting and peeling treatment on the accumulated iron filings on the filtrate plate, preventing a large amount of dropped iron filings from accumulating on the filtrate plate and squeezing into the filter holes, resulting in some iron filings being embedded in the filter holes and being difficult to clean out when being scraped. A slanting concave plate is rotatably connected to the outer side of the inner long rod near the transmission wheel through a bearing. When the slanting concave plate moves, it shovels and cleans the position on the filtrate plate that the transmission wheel is about to contact, preventing too much iron filings from accumulating at the position on the filtrate plate that the transmission wheel is about to contact and being pressed into the filter holes by the transmission wheel and being difficult to handle. An arc-shaped scraping block is fixedly connected to the outer side of the slanting concave plate. By setting an arc-shaped scraping block on the slanting concave plate, the outer surface of the transmission wheel is scraped and cleaned, preventing iron filings from gradually adhering to the surface of the transmission wheel after long-term use and gradually affecting the use effect of the transmission wheel. An inner thorned plate is fixedly connected to the top of the inner wall of the concave connecting plate. By setting an inner thorned plate on the top of the inner wall of the concave connecting plate, a poking and combing treatment is performed on the rigid arc brush, preventing too much mixture of cutting fluid and iron filings from adhering to the surface of the rigid arc brush after long-term use and being difficult to handle, which affects the subsequent cleaning effect. The top of the concave connecting plate is slidably connected to the bottom of the electric slide rail. There are two slanting concave plates, and the two slanting concave plates are symmetrically distributed on the outer side of the inner long rod with the transmission wheel as the center.

[0012] Furthermore, the cleaning mechanism includes a long threaded rod, a square sleeve plate is sleeved on the outer side of the long threaded rod and threadedly connected, and a conical concave plate is sleeved on the outer side of the square sleeve plate and fixedly connected. The conical concave plate is arranged on the outer side of the long threaded rod to surround, cover and protect the area around the long threaded rod, so as to prevent a large amount of iron filings generated by tapping from falling on the thread surface of the long threaded rod and affecting the thread matching effect with the square sleeve plate. Both sides of the square sleeve plate are fixedly connected with folding scrapers, and the folding scrapers always scrape and clean the outer surface of the conical concave plate when moving, so as to prevent excessive iron filings from continuously accumulating on the conical concave plate, covering and blocking the heat dissipation bottom holes at the bottom of the bottom shell, affecting the heat dissipation effect. The side of the folding scraper away from the square sleeve plate is fixedly connected with a square shaped scraper, the square scraper pushes the accumulated iron chips to move toward the chip removal long hole as the folding scraper moves, to prevent a large amount of iron chips from accumulating on the filtrate plate after a long period of tapping, covering and blocking the filtrate hole and affecting the passage of the cutting liquid. One side of the square scraper is fixedly connected with a long connecting rod, and the end of the long connecting rod away from the square scraper is fixedly connected with a square blocking plate. When the square blocking plate moves back to the inside of the chip removal long hole, the chip removal long hole is filled and blocked to prevent a part of the cutting liquid that falls with the iron chips from seeping out of the chip removal long hole to the outside and becoming difficult to handle. One end of the threaded long rod is fixedly connected to the driving shaft of the servo motor, the bottom of the square sleeve plate is slidably connected to the top of the filtrate plate, and one side of the conical concave plate is fixedly connected to the inner wall of the collecting box.

[0013] The present invention provides a rebar sleeve bidirectional tapping device, which has the following beneficial effects:

[0014] 1. The rebar sleeve bidirectional tapping device drives the top rebar sleeve to change direction by rotating the top connecting rod to realize bidirectional tapping processing, so as to prevent the existing tapping processing equipment from requiring manual removal of the rebar sleeve to change direction when performing bidirectional tapping processing on the rebar sleeve, which is time-consuming and labor-intensive and also has safety hazards. By arranging a built-in barbed plate on the top of the inner wall of the concave connecting plate to perform a toggle combing treatment on the hard arc brush, it is prevented that the hard arc brush will not adhere to too much chip liquid and iron chip mixture on the surface after long-term use, which is difficult to handle and affects the subsequent cleaning effect. When the square scraper moves with the folded scraper, it pushes the accumulated iron chips to move in the direction of the chip removal long hole, so as to prevent a large amount of iron chips from accumulating on the filtrate plate after long-term tapping processing, covering and blocking the filtrate holes and affecting the passage of the chip liquid.

When the long scraper rod rotates, the top surface of the inner long plate is scraped to clean the iron chips, so as to prevent a large amount of iron chips from falling and accumulating on the inner long plate after the equipment performs tapping processing for a long time and being difficult to be uniformly collected and processed. By arranging an arc sliding hole and a cross sliding block on the outer side of the inner long plate, the long scraper rod is subjected to a resisting limit correction, so as to prevent the bottom support block driven by the driving motor from rotating to a position flush with the tap through naked eye observation when turning the direction, resulting in errors in the tapping processing. By arranging a bottom housing on the outer side of the driving motor to wrap it for protection and opening a heat dissipation bottom hole at the bottom of the bottom housing for heat dissipation, it is prevented that the driving motor placed at the bottom of the inner long plate is easily attached to the falling iron chips and the surrounding is covered to affect the heat dissipation efficiency.

[0016] 3. The two-way tapping device for the steel sleeve is provided with a stripping mechanism, and the hard arc brush is used to lift and strip the accumulated iron filings on the filtrate plate when rotating with the built-in long stick, so as to prevent a large amount of fallen iron filings from accumulating on the filtrate plate and being squeezed and mixed in the filter holes, causing a part of the iron filings to be embedded in the filter holes and difficult to be cleaned out when being scraped; a built-in barbed plate is provided on the top of the inner wall of the concave connecting plate to perform a toggle-type combing treatment on the hard arc brush, so as to prevent the hard arc brush from adhering to too much mixture of cutting fluid and iron filings after long-term use, which is difficult to handle and affects the subsequent cleaning effect; when the inclined concave plate moves, the position on the filtrate plate that the transmission wheel is about to contact is scraped and cleaned, so as to prevent the position on the filtrate plate that the transmission wheel is about to contact from accumulating too much iron filings and being pressed into the filter holes by the transmission wheel and difficult to handle; an arc-shaped scraper block is provided on the inclined concave plate to scrape and clean the outer surface of the transmission wheel, so as to prevent the transmission wheel from gradually adhering to the surface of the transmission wheel after long-term use, which is not cleaned in time and gradually affects the use effect of the transmission wheel.

[0017] 4. The bidirectional tapping device for the steel bar sleeve is provided with a cleaning mechanism, which surrounds and covers the area around the threaded long rod by arranging a conical concave plate on the outer side of the threaded long rod to prevent a large amount of iron chips generated by the tapping process from falling on the thread surface of the threaded long rod and affecting the thread matching effect with the square sleeve plate; the outer surface of the conical concave plate is scraped and cleaned at all times when the folding scraper moves to prevent excessive iron chips from continuously accumulating on the conical concave plate, covering and blocking the heat dissipation bottom hole at the bottom of the bottom sleeve shell and affecting the heat dissipation effect; the square scraper pushes the accumulated iron chips to move toward the chip removal long hole as the folding scraper moves, to prevent a large amount of iron chips from accumulating on the filtrate plate after a long period of tapping, covering and blocking the filtrate hole and affecting the passage of the chip liquid; the square blocking plate is moved back to the chip removal long hole to fill and block the chip removal long hole, to prevent a part of the chip liquid that falls with the iron chips from seeping out from the chip removal long hole to the outside and being difficult to handle.

One side of the plate 1003 is fixedly connected to the inner wall of the collecting box 5. When in use, before cleaning and removing the accumulated iron filings on the filtrate plate 13, the concave connecting plate 901 is driven by the electric slide rail 8 to move in the direction of the chip removal long hole 12. The movement of the concave connecting plate 901 drives the inner built-in long stick 902 and the transmission wheel 903 to move together. When the transmission wheel 903 moves, it is in rolling contact with the top surface of the filtrate plate 13 at all times. When the transmission wheel 903 rolls, it drives the built-in long stick 902 and the hard arc brush 904 on the surface to rotate. When the hard arc brush 904 rotates with the built-in long stick 902, the accumulated iron filings on the filtrate plate 13 are lifted and peeled off.

When the folding scraper 1004 moves, it scrapes and cleans the outer surface of the conical concave plate 1003 at all times. When the folding scraper 1004 moves, the square scraper 1005 pushes the accumulated iron chips to move toward the chip removal long hole 12.A large amount of iron filings are pushed by the square scraping plate 1005 to a position close to the chip discharge long hole 12, and then the concave connecting plate 901 is driven to reciprocate by the electric slide rail 8 to discharge the accumulated iron filings outside the chip discharge long hole 12.

After the tapping is completed, the electric push rod 2 drives the pressing block 3 to move back upward to release the pressing and fixing of the steel sleeve. At this time, the steel sleeve on the bottom support block 7 is turned 180 degrees by the turning mechanism 6, and then it is pressed, fixed and tapped to realize automatic two-way tapping. The iron chips generated by the tapping and the chip liquid with lubrication will fall downward onto the filtrate plate 13 in the collection box 5, and the iron chips will accumulate on the filtrate plate 13, and the chip liquid will pass through the filtrate plate 13 for storage At the bottom of the inner wall of the collecting box 5, the chip liquid collected at the bottom of the inner wall of the collecting box 5 is pumped into the concave connecting pipe 15 by a high-pressure water pump 14 and sprayed on the processed steel sleeve again for recycling. When no tapping is performed, the stripping mechanism 9 is driven by the electric slide rail 8 to move on the filtrate plate 13 to lift and strip the mixed iron chips on the filtrate plate 13. After the iron chips are stripped by the stripping mechanism 9, the motor is started to drive the cleaning mechanism 10 to scrape and clean the iron chips stripped off the filtrate plate 13 and push the scraped and cleaned accumulated iron chips to the position of the chip discharge long hole 12 and discharge them outward from the chip discharge long hole 12. After the tapping of one end of the steel sleeve on the bottom support block 7 is completed, the electric push rod 2 drives the pressing block 3 to release the pressure on the steel sleeve. When the top connecting rod 603 rotates, the steel sleeve is driven to rotate together through the bottom supporting block 7 at the top. The top connecting rod 603 is used to drive the top steel sleeve to change direction to realize bidirectional tapping. When the top connecting rod 603 rotates, the long scraper rod 604 on the outside is driven to rotate together. When the long scraper rod 604 rotates, the top surface of the inscribed long plate 601 is scraped to clean the iron filings. When the long scraper rod 604 rotates to contact the cross slider 609, it pushes the cross slider 609 to slide in the arc hole of the arc block 607. When the long scraper rod 604 pushes the cross slider 609 to slide in the arc sliding hole 608 to one side and is resisted, the long scraper rod 604 is aligned parallel to the tap of the tapping machine 4. By setting an arc-shaped sliding hole 608 and a cross slider 609 on the outside of the inner long plate 601, the long scraper rod 604 is corrected by a resisting limit, and by setting a bottom casing 605 on the outside of the driving motor 602 to wrap it for protection and opening a heat dissipation bottom hole 606 at the bottom of the bottom casing 605 for heat dissipation, before cleaning and removing the accumulated iron chips on the filtrate plate 13, the concave connecting plate 901 is driven by the electric slide rail 8 to move toward the chip removal long hole 12, and the movement of the concave connecting plate 901 drives the inner built-in long stick 902 and the transmission wheel 903 to move together, and the transmission wheel 903 is in rolling contact with the top surface of the filtrate plate 13 at all times when moving, and the transmission wheel 903 drives the built-in long stick 902 and the hard arc brush 904 on the surface to rotate when rolling.When the hard arc brush 904 rotates with the built-in long stick 902, the accumulated iron filings on the filtrate plate 13 are lifted and peeled off. When the hard arc brush 904 rotates with the built-in long stick 902 to a position close to the top of the inner wall of the concave connecting plate 901, it will be in contact with the built-in thorn plate 907. The built-in thorn plate 907 is set on the top of the inner wall of the concave connecting plate 901 to perform a toggle combing treatment on the hard arc brush 904. When the built-in long stick 902 rotates, the inclined concave plate 905 connected to the outside by the bearing does not rotate together. The inclined concave plate 905 is connected to the inner wall of the concave connecting plate 901 by the built-in long stick 902. 02 As the concave connecting plate 901 moves, the inclined concave plate 905 moves to scrape and clean the position on the filtrate plate 13 that the transmission wheel 903 is about to contact. When the transmission wheel 903 rotates, the outer surface is always in contact with one side of the arc scraper 906. The arc scraper 906 is arranged on the inclined concave plate 905 to scrape and clean the outer surface of the transmission wheel 903. After the stripping mechanism 9 strips the accumulated iron filings on the filtrate plate 13, the servo motor 11 is started to drive the threaded long rod 1001 to rotate. When the threaded long rod 1001 rotates, it drives the conical concave The square sleeve 1002 whose inner wall is locked and limited is threadedly moved in a straight line, and a conical concave plate 1003 is arranged on the outer side of the threaded long rod 1001 to surround and cover the area around the threaded long rod 1001. When the square sleeve 1002 moves, it drives the folding scraper 1004, the square scraper 1005, the long connecting rod 1006 and the square blocking plate 1007 to move together. When the folding scraper 1004 moves, it scrapes and cleans the outer surface of the conical concave plate 1003 at all times. The square scraper 1005 moves along with the folding scraper 1004. When moving, the accumulated iron chips are pushed to move toward the chip removal long hole 12. A large amount of iron chips are pushed to a position close to the chip removal long hole 12 by the square scraper 1005, and then the electric slide rail 8 drives the concave connecting plate 901 to reciprocate to discharge the accumulated iron chips out of the chip removal long hole 12. After cleaning, the servo motor 11 drives the threaded long rod 1001 to reverse so that the square sleeve plate 1002 moves back. When the square sleeve plate 1002 moves back, it drives the square blocking plate 1007 to move back together. When the square blocking plate 1007 moves back to the inside of the chip removal long hole 12, the chip removal long hole 12 is filled and blocked.
