Description

Technical Field

[0002] In industrial production, in order to meet the actual use requirements and process requirements, it is necessary to punch holes in the steel pipe through a punching device; Chinese patent CN110711872B discloses a multi-head punching machine for steel processing. When drilling a steel pipe, the device places a round pipe in a positioning groove, and then clamps and fixes it through a clamping piece, so that the drill seat moves radially to drill holes. However, during the processing, due to the limitations of the positioning groove and the clamping piece, the drill bit can only drill holes on one side of the steel pipe. When it is necessary to drill holes on multiple sides of the steel pipe, the drilled steel pipe is drilled again. However, after the steel pipe is placed in a feeding device, the steel pipe naturally falls into the positioning groove, and the positioning groove drives the steel pipe therein to rotate. During this process, friction will be generated on the contact surface of the steel pipe and the clamping piece. The steel pipe rolls in the positioning groove under the action of friction, so that the position of the second drilling surface cannot be determined, thereby failing to complete the multi-sided drilling of the steel pipe.

[0019] Embodiment 1

[0020] See also Figure 1-Figure 8A multi-point positioning automatic punching device for steel, comprising a processing table 1 and a collecting tank 11 opened in the middle of the processing table 1, characterized in that: the processing table 1 is provided with a clamping assembly 2, a driving assembly 3, a positioning assembly 4 and a drilling device 5, a plurality of drilling devices 5 are sequentially installed on the side of the processing table 1 to perform multi-station drilling on a steel pipe 6, located on one side of the collecting tank 11, a clamping assembly 2 is installed under each drilling device 5, when the drilling device 5 drills the steel pipe 6, the clamping assembly 2 clamps and fixes the steel pipe 6 in the radial direction, the driving assembly 3 is installed in the middle of the processing table 1, located directly above the collecting tank 11, the positioning assembly 4 comprises a bearing platform 41, a driving disk 43, a sliding column 46 and a fixed clamping claw 48, two bearing platforms 41 are symmetrically matched on the driving assembly 3, respectively located at the two ends of the collecting tank 11, a driving disk 43 is installed on the side of the bearing platform 41 facing the collecting tank 11, when drilling the steel pipe 6, the driving component 3 drives the two bearing platforms 41 to move toward each other, and the two ends of the steel pipe 6 are clamped by the driving disk 43 thereon, and the sliding column 46 and a plurality of fixed jaws 48 are successively installed in the driving disk 43, and one end of the sliding column 46 and the fixed jaw 48 are extended from the driving disk 43, and the sliding column 46 is connected to the fixed jaw 48. When the driving disk 43 clamps the steel pipe 6, the two ends of the steel pipe 6 push the extended end of the sliding column 46 into the driving disk 43, and the sliding column 46 drives the fixed jaw 48 to clamp and fix the pipe wall of the steel pipe 6. When the drilling surface of the steel pipe 6 is switched, the driving disk 43 drives the steel pipe 6 to rotate on the clamping component 2.

[0021] When in use, first start the clamping assembly 2 and the driving assembly 3 to open the closed clamping assembly 2, and at the same time, the driving assembly 3 drives the supporting platform 41 of the positioning assembly 4 to move to the two ends of the processing table 1 respectively, so that the loading tables on both sides of the processing table 1 pull the distance between the two driving disks 43 to the maximum, and then the driving assembly 3 stops working, and then the steel pipe 6 to be drilled is placed on the opened clamping assembly 2, and the suspended driving assembly 3 is started again to drive the supporting platforms 41 on both sides of the processing table 1 to move to the two ends of the steel pipe 6 on the clamping assembly 2, and at the same time, the opened clamping assembly 2 is closed to clamp the steel pipe 6 thereon. When the driving disk 43 contacts the two ends of the steel pipe 6, the tube wall of the steel pipe 6 will enter the opened fixed jaws 48, and then the sliding column 46 extending from the driving disk 43 will be pushed back into the driving disk 43. When the sliding column 46 is pushed back into the driving disk 43, the fixed jaws 48 are pulled to drive the opened fixed jaws 48 to close. When the extended end of the sliding column 46 is completely pushed into the driving disk 43 by the steel pipe 6, the fixed jaws 48 clamp the tube wall of the steel pipe 6 and fix it, so that the steel pipe 6 cannot rotate. At the same time, the loading tables on both sides of the processing table 1 complete the clamping of the two ends of the steel pipe 6 through the driving disks 43 thereon, and the steel pipe 6 is axially pressed. 6 is fixed, the driving assembly 3 stops working, and then the clamping assembly 2 is closed to clamp and fix the steel pipe 6 in the radial direction. When the axial and radial directions of the steel pipe 6 are fixed, the drilling devices 5 at multiple stations on the processing table 1 start to drill the fixed steel pipe 6. The debris and cutting fluid generated during the drilling process will fall into the collecting tank 11 below and be collected. After drilling a hole on this side of the steel pipe 6 and needing to drill a hole on the next side, after the drilling device 5 stops working, the clamping assembly 2 releases the steel pipe 6 to allow the steel pipe 6 to rotate radially, and then the driving disk 43 drives the steel pipe 6 to rotate radially, flipping the next drilling surface to Under the drilling device 5, after the clamping component 2 clamps and fixes the steel pipe 6 again, the drilling device 5 drills the surface again, and repeats this process until all the surfaces to be processed of the steel pipe 6 are drilled. Then the drilling device 5 stops working, the clamping component 2 releases the clamped steel pipe 6, and the driving component 3 drives the stage to move to both sides of the processing table 1, so that the driving disk 43 releases the clamped steel pipe 6. During this process, the sliding column 46 pushed into the driving disk 43 extends out from the driving disk 43 again and pushes the fixed clamping claw 48 to open. After taking out the processed steel pipe 6, the next steel pipe 6 to be processed is placed, and the above steps are repeated for processing.

[0022] The difference from the above embodiment is that two fixed seats 12 are symmetrically fixedly installed on the processing table 1, and the two fixed seats 12 are respectively located at the two ends of the collecting tank 11, and a sliding rod 13 is arranged between the two fixed seats 12, and the two ends of the sliding rod 13 are respectively fixedly connected to the two fixed seats 12 on one side of the collecting tank 11, and a limiting protrusion 14 is fixedly installed on both sides of the processing table 1, and the limiting protrusion 14 is located on one side of the fixed seat 12.

[0023] When the carrying platform 41 moves, the slide bar 13 and the limiting protrusion 14 limit and guide the carrying platform 41 to prevent the carrying platform 41 from deviating during the movement.

[0024] The difference from the above-mentioned embodiment lies in that a limiting groove 411 is provided in the middle of the bottom of the supporting platform 41, the supporting platform 41 is slidably mounted on the limiting protrusion 14 through the limiting groove 411, the slide rod 13 slides through one side of the supporting platform 41, a support shaft 42 is fixedly mounted on the upper end of the supporting platform 41 facing the collecting tank 11, a driving disk 43 is rotatably mounted on the support shaft 42, an outer side of the driving disk 43 is coaxially fixedly connected with an outer gear ring 431, a sliding groove 44 and a plurality of claw grooves 45 are provided in the driving disk 43 in sequence, and a plurality of claw grooves 45 are provided on the side of the driving disk 43 facing the collecting tank 11, and are evenly arranged in a circular shape thereon.

[0025] When the loading platform fixes the steel pipe 6 axially through the driving disk 43, the two ends of the steel pipe 6 will contact the contact protrusion 461 extended from the sliding column 46 after entering the opened fixed claws 48. The contact protrusion 461 is pushed into the sliding groove 44 and causes the sliding column 46 to compress the support spring 47. In the process of the sliding column 46 compressing the support spring 47, the sliding column 46 pulls the pull rod 462 in the same direction, so that the opened fixed claw 48 is closed toward the middle of the claw groove 45, thereby clamping the tube wall of the steel pipe 6. When the loading platform drives the driving disk 43 away from the two ends of the steel pipe 6, the compressed support spring 47 loses the thrust that compresses it, thereby restoring its deformation, pushing the sliding column 46 outward, causing the contact protrusion 461 to extend out of the driving disk 43 again. When the sliding column 46 moves outward, it pushes the pull rod 462 to move in the same direction, thereby causing the closed fixed claw 48 to open toward the two ends of the claw groove 45.

[0026] The difference from the above-mentioned embodiment lies in that the sliding column 46 is slidably installed in the sliding groove 44, and the protruding end of the sliding column 46 is composed of a plurality of interference protrusions 461 which are evenly arranged in a circular shape, and a support spring 47 is fixedly connected between the other end of the sliding column 46 and the inner wall of the sliding groove 44. When the steel pipe 6 is not clamped, the support spring 47 pushes the sliding column 46 to make the interference protrusion 461 extend from the driving disk 43, and a pull rod 462 is fixedly connected to one side of the sliding column 46, and a pull rod 462 is provided between every two interference protrusions 461, and the fixed clamping jaw 48 is rotatably installed in the clamping jaw groove 45 through a rotating shaft, and is rotatably connected to the pull rod 462. When the interference protrusion 461 extends out of the driving disk 43, the pull rod 462 is pushed to open the fixed clamping jaw 48.

[0027] The difference from the above embodiment is that the positioning assembly 4 also includes a driving cylinder 412 and a connecting plate 413. The driving cylinder 412 is fixedly installed on the outward side of the supporting platform 41. The output shaft of the driving cylinder 412 is fixedly connected to one end of the connecting plate 413. The other end of the connecting plate 413 is fixedly connected to a driving rack 414. The driving rack 414 is slidably installed on the other side of the supporting platform 41, and the driving rack 414 is meshed with the lower end of the outer gear ring 431.

[0028] Among them, when the drilling surface of the steel pipe 6 needs to be replaced, the driving cylinder 412 extends the output shaft and pulls the driving rack 414 to move a certain distance in the same direction through the connecting plate 413, so that the outer gear ring 431 drives the driving disk 43 to rotate a corresponding angle on the support shaft 42, and the surface to be drilled of the steel pipe 6 is flipped to the processing position. After the processing of a steel pipe 6 is completed, the driving cylinder 412 retracts the output shaft and pulls back the driving rack 414 that has traveled a certain distance.

[0029] The difference from the above embodiment is that the driving assembly 3 includes a driving motor 31 and a bearing seat 32. The driving motor 31 is fixedly mounted at one end of the processing table 1. The two bearing seats 32 are fixedly mounted on the processing table 1 and are symmetrically distributed at both ends of the collecting tank 11, located on one side of the limiting protrusion 14. A bidirectional threaded rod 33 is rotatably connected between the two bearing seats 32. The threads on both ends of the bidirectional threaded rod 33 are in opposite directions. The other sides of the two supporting platforms 41 are threadedly assembled on both ends of the bidirectional threaded rod 33. One end of the bidirectional threaded rod 33 is coaxially fixedly connected to the output shaft of the driving motor 31.

[0030] When the support platform 41 needs to be driven to move toward each other, the driving motor 31 drives the bidirectional threaded rod 33 to rotate forward on the bearing seat 32. When the support platform 41 needs to be driven to move backward, the driving motor 31 drives the bidirectional threaded rod 33 to rotate backward on the bearing seat 32.

[0031] The difference from the above embodiment is that the drilling device 5 includes a drill bit seat 51, a drill bit 52 and a water injection nozzle 53, the drill bit seat 51 is fixedly mounted on the processing table 1, the drill bit 52 is movably mounted on the upper end of the drill bit seat 51, the drill bit 52 is located above the collecting tank 11, and the water injection nozzle 53 is fixedly connected to one side of the drill bit 52.

[0032] After the steel pipe 6 is completely fixed, the drill bit 52 on the drill bit seat 51 starts to drill the steel pipe 6. At the same time, the water injection nozzle 53 sprays cutting fluid to the drilling hole. The cutting fluid mixed with the debris drilled by the drill bit 52 falls into the collection tank 11.

[0033] The difference from the above-mentioned embodiment is that the clamping assembly 2 includes a clamping seat 21, a fixed claw 22, a movable claw 24 and a clamping cylinder 25. The fixed end of the clamping seat 21 is fixedly connected to the drill bit seat 51, and the clamping end of the clamping seat 21 extends to directly below the drill bit 52 and is suspended above the collecting tank 11. The fixed claw 22 is fixedly installed on the clamping end of the clamping seat 21. A clamping slide rail 23 is fixedly connected to the clamping seat 21. The clamping slide rail 23 is located on one side of the fixed claw 22. The movable claw 24 is slidably installed on the clamping slide rail 23. The clamping cylinder 25 is fixedly installed on the fixed end of the clamping seat 21, and the output shaft of the clamping cylinder 25 is fixedly connected to one side of the movable claw 24.

[0034] Among them, when the clamping assembly 2 radially clamps the steel pipe 6, the clamping cylinder 25 pushes the movable claw 24, driving the movable claw 24 to slide on the clamping slide rail 23 toward the fixed claw 22, thereby radially clamping the steel pipe 6, and there is a clamping assembly 2 corresponding to each drilling device 5. When the drilling device 5 drills the steel pipe 6 again, the clamping seat 21 of the clamping assembly 2 lifts the steel pipe 6 under the drill bit 52, providing a support point for the drill bit 52, so that the drilling effect is better. When the clamping assembly 2 needs to release the steel pipe 6, the clamping cylinder 25 pulls the movable claw 24, driving the movable claw 24 to slide on the clamping slide rail 23 in the direction away from the fixed claw 22, thereby releasing the clamped steel pipe 6.

[0035] Embodiment 2

[0036] The difference from the above-mentioned embodiment is that a waste bucket 15 is provided under the processing table 1 , and the waste bucket 15 is fixedly installed at the bottom of the processing table 1 and located at one side of the collecting tank 11 .

[0037] The difference from the above embodiment is that a filter screen 111 is fixedly connected to the middle of the collecting tank 11, a collecting bucket 112 is fixedly connected to the bottom of the collecting tank 11, one end of the collecting bucket 112 is located directly below the filter screen 111, and the other end of the collecting bucket 112 is tilted downward to the top of the waste barrel 15.

[0038] Among them, after the cutting fluid mixed with debris falls into the collecting tank 11, the filter screen 111 will filter out the debris in the cutting fluid, and the cutting fluid filtered by the filter screen 111 will pass through the filter screen 111 and fall into the collecting bucket 112 below it, and flow into the waste barrel 15 along the collecting bucket 112 to be collected.

[0039] Working principle: When in use, first start the clamping assembly 2 and the driving assembly 3, the clamping cylinder 25 pulls the movable claw 24, drives the movable claw 24 to slide on the clamping slide rail 23 in the direction away from the fixed claw 22, and opens the closed clamping assembly 2. At the same time, the driving motor 31 of the driving assembly 3 drives the bidirectional threaded rod 33 to rotate forward on the bearing seat 32, thereby driving the bearing platforms 41 at both ends of the bidirectional threaded rod 33 to move toward the two ends of the processing table 1 respectively, so that the loading tables on both sides of the processing table 1 increase the distance between the two driving disks 43. After the pull is pulled to the maximum, the driving assembly 3 stops working, and then the steel pipe 6 to be drilled is placed on the opened clamping assembly 2. The suspended driving assembly 3 is started again, and the driving motor 31 drives the bidirectional threaded rod 33 to rotate in the opposite direction on the bearing seat 32, driving the bearing tables 41 on both sides of the processing table 1 to move toward the two ends of the steel pipe 6 on the clamping assembly 2. At the same time, the clamping cylinder 25 pushes the movable claw 24, driving the movable claw 24 to slide on the clamping slide rail 23 toward the fixed claw 22, thereby radially clamping the steel pipe 6; When the driving disk 43 contacts the two ends of the steel pipe 6, the tube wall of the steel pipe 6 will enter the opened fixed clamping claw 48 and contact the contacting protrusion 461 extended from the sliding column 46. The contacting protrusion 461 is pushed into the sliding groove 44 and causes the sliding column 46 to compress the supporting spring 47. In the process of the sliding column 46 compressing the supporting spring 47, the sliding column 46 pulls the pull rod 462 in the same direction to close the opened fixed clamping claw 48 toward the middle of the clamping claw groove 45, thereby clamping the tube wall of the steel pipe 6 and preventing the steel pipe 6 from rotating. At the same time, the loading platforms on both sides of the processing table 1 complete the clamping of the two ends of the steel pipe 6 through the driving disk 43 thereon, and fix the steel pipe 6 from the axial direction of the steel pipe 6, driving The moving component 3 stops working, and then the clamping component 2 is closed to clamp and fix the steel pipe 6 in the radial direction. When the axial and radial directions of the steel pipe 6 are fixed, the drill bits 52 on the drill bit seats 51 at multiple stations on the processing table 1 start to drill holes in the steel pipe 6. At the same time, the water injection nozzle 53 sprays cutting fluid to the drilling hole, and the cutting fluid mixed with the debris drilled by the drill bit 52 falls into the collection tank 11. After the cutting fluid mixed with the debris falls into the collection tank 11, the filter screen 111 will filter out the debris in the cutting fluid, and the cutting fluid filtered by the filter screen 111 will pass through the filter screen 111 and fall into the collection bucket 112 below it, and flow into the waste barrel 15 along the collection bucket 112 to be collected; After drilling a hole on this side of the steel pipe 6 and needing to drill a hole on the next side, after the drilling device 5 stops working, the clamping assembly 2 releases the steel pipe 6 to allow the steel pipe 6 to rotate radially, and then drives the cylinder 412 to extend the output shaft, and pulls the drive rack 414 to move a certain distance in the same direction through the connecting plate 413, so that the outer gear ring 431 drives the drive disk 43 to rotate a corresponding angle on the support shaft 42, and the surface to be drilled of the steel pipe 6 is turned over to the processing position. After the clamping assembly 2 clamps and fixes the steel pipe 6 again, the drilling device 5 drills the surface again, and repeats this process until all the surfaces to be processed of the steel pipe 6 are drilled. When the device 5 stops working, the clamping assembly 2 releases the clamped steel pipe 6, and the driving assembly 3 drives the stage to move to both sides of the processing table 1, so that the driving disk 43 releases the clamped steel pipe 6. In this process, the compressed supporting spring 47 loses the thrust that compresses it, thereby recovering its deformation, pushing the sliding column 46 outward, and making the abutting protrusion 461 extend out of the driving disk 43 again. When the sliding column 46 moves outward, it pushes the pull rod 462 to move in the same direction, so that the closed fixed clamping claw 48 opens to the two ends of the clamping claw groove 45. After taking out the processed steel pipe 6, the next steel pipe 6 to be processed is placed, and the above steps are repeated for processing.

[0040] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
