Description

Technical Field

[0001] The invention relates to the technical field of plasma cutting processing, and in particular to an arc cutting process for producing a finger-type chuck. Background Art

[0002] Finger chuck is a common fixture, mainly used for clamping workpieces in mechanical processing. Its working principle is to clamp and position the workpiece through the radial movement of the movable jaws evenly distributed on the chuck body. It is a machine tool accessory. When the finger chuck is produced and processed, the surface of the chuck body is opened by arc cutting, etc. The plasma cutting process is generally used for processing, but a lot of smoke and waste residue will be generated during cutting. When the cutting is completed, the temperature of the chuck body is very high and it needs to be cooled before it can be taken out.

[0003] Chinese patent publication number CN221695306U discloses a drilling device for producing chucks of numerical control machine tools, comprising a housing: a mounting seat is slidably connected to the top of the housing, a cylinder is fixedly installed on the front side of the mounting seat, an L-shaped mounting plate is fixedly connected to the output end of the cylinder, the L-shaped mounting plate slides on the front side of the mounting seat, and a drilling device is installed at the bottom of the L-shaped mounting plate. The utility model drills holes on the chuck through the drilling device, aligns the universal water spray head with the drill bit of the drilling device, and thus washes down the debris. After simple filtration through the filter plate, large particles of debris will remain on the surface of the filter plate, and fine debris and cutting fluid will enter the inner cavity of the cylindrical filter tube for filtration. Due to gravity, the debris is precipitated into the inner cavity of the sedimentation bucket, and the filtered cutting fluid enters the inner cavity of the cutting fluid recovery chamber. The debris is recovered by pulling out the filter plate and opening the valve at the bottom of the sedimentation bucket, so as to achieve the purpose of facilitating the collection of debris and recycling the cutting fluid.

[0004] Regarding the above-mentioned related technologies: When cutting the disk body of the finger-type chuck, many cutting methods are linear cutting from top to bottom, and the cutting direction is relatively single. For example, the side of the disk body of the finger-type chuck will also be processed with holes. Faced with such a single cutting direction of the workpiece, it is necessary to adjust the placement position or angle of the workpiece. However, since the temperature of the disk body after cutting is very high, it is not convenient to adjust the position. Therefore, this problem can be avoided during multi-directional cutting.

[0016] An arc cutting process for producing a finger-type chuck comprises the following steps:

[0017] S1, loading process: when the finger-type chuck disc body is subjected to hole cutting processing, the finger-type chuck disc body is first placed into the inner wall of the feed rack, and the feed push rod pushes the feed push plate to move, so that the finger-type chuck disc body is pushed away from the inner wall of the feed rack through the through-port on the left, and then pushed to the position in the middle of the top wall of the placement rack. When the limit slider is located at the bottom of the inner wall of the corresponding limit slide groove, the placement rack is level with the through-port. When the limit slider is located at the top of the inner wall of the corresponding limit slide groove, the placement rack is level with the top wall of the processing table. The lifting seat and the lifting rack are pushed up by the movable end of the lifting push rod installed in the installation cavity. When the lifting rack rises, it will drive the limit slider to slide upward along the inner wall of the corresponding limit slide groove and rise inside the lifting cavity. The lifting rack simultaneously drives the slag collecting frame, the placement rack and the finger-type chuck disc body to rise, so that the placement rack is level with the processing table, so that the processing table enters the inner cavity of the sealing cover;

[0018] S2, clamping process: when the finger-type chuck body is located inside the slag blocking frame, the photoelectric sensor senses the finger-type chuck body, and then the electric push rod pushes the arc clamp seat to move and clamp the finger-type chuck body to prevent the finger-type chuck body from moving during cutting and causing cutting misalignment. When the finger-type chuck body is clamped and fixed;

[0019] S3, adjustment process: start the plasma cutting machine to start working, and adjust the position of the cutting torch burner according to the position of the opening of the finger-type chuck disc body, and make the electric slider 1 move left and right on the electric slide rail 1, thereby driving the moving frame and the electric slide rail 2 to move, and the electric slide rail 2 simultaneously drives the electric push rod 1, the moving seat, the lifting plate, the electric telescopic rod, the connecting seat, the fixed frame and the cutting torch burner to move. When it is necessary to adjust the forward and backward movement position of the cutting torch burner, make the electric slider 2 move forward and backward in the inner wall of the electric slide rail 2, thereby driving the electric push rod 1, the moving seat, the lifting plate, the electric telescopic rod, the connecting seat, the fixed frame and the cutting torch burner to move, and the electric push rod 1 pushes the lifting plate down to drive the electric telescopic rod, the connecting seat, the fixed frame and the cutting torch burner to move downward, and the plasma cutting machine, the connecting seat and the cutting torch burner work together. The top of the finger-type chuck body is used for cutting and opening. When the side of the finger-type chuck body needs to be opened, when the angle of the cutting torch burner needs to be adjusted forward, the movable end of the electric telescopic rod located at the front is retracted, and the movable end of the electric telescopic rod located at the rear is extended, thereby driving the connecting seat to flip forward, and the connecting seat drives the steering seat, the fixed frame, the connecting seat and the cutting torch burner to flip forward. When the angle of the cutting torch burner needs to be adjusted backward, the movable end of the electric telescopic rod located at the rear is retracted, and the movable end of the electric telescopic rod located at the front is extended, thereby driving the connecting seat to flip backward, and the connecting seat drives the steering seat, the fixed frame, the connecting seat and the cutting torch burner to flip backward. When the left and right use angles of the cutting torch burner need to be adjusted, the reduction motor drives the rotating shaft and the steering seat to rotate on the inner wall of the groove, thereby driving the fixed frame, the connecting seat and the cutting torch burner to rotate left and right to adjust the angle.

[0020] S4, cutting process: when the finger-type chuck body is cut and opened by the cutting torch burner, a lot of waste slag will be generated and fall into the slag collecting frame through the placement rack for unified collection, and the slag blocking rack can prevent the waste slag from splashing during the processing. At the same time, when the plasma cutting machine is working, the drive motor is started to drive the smoke exhaust fan to rotate on the annular frame, and the smoke generated during the processing is filtered through the smoke filter from the sealing cover and discharged through the smoke outlet;

[0021] S5, discharging process: when the finger-type chuck disc body is processed, the movable end of the lifting push rod contracts to drive the lifting seat and the lifting frame to descend. When the lifting frame descends, it will drive the limit slider to slide downward along the inner wall of the corresponding limit slide groove, and the lifting frame will simultaneously drive the slag collecting frame, the placing frame and the finger-type chuck disc body to descend, so that the placing frame and the finger-type chuck disc body on the inner wall of the through-port are horizontally entered into the lifting cavity. When processing two finger-type chuck disc bodies of different specifications, the feeding push rod continuously pushes the feeding push plate to move into the lifting cavity, and pushes the finger-type chuck disc body that has been processed on the top wall of the placing frame to the through-port on the right, and then falls into the collection frame through the corresponding inclined groove for cooling. The finger-type chuck disc body of another specification can be pushed by the discharging push rod to push the discharging push plate to push the finger-type chuck disc body that has been processed on the top of the placing frame to the through-port at the rear, and slides into the collection frame at the rear through the inclined groove for unified collection, and the finger-type chuck disc bodies of different specifications can be placed in batches to prevent mixing and avoid subsequent sorting;

[0022] S6. Cooling process: Since the temperature of the finger chuck body is very high just after cutting, when it is placed in the collection frame, a fan can be placed at the position corresponding to the collection frame outside the entire device to accelerate the cooling time of the finger chuck body. After the cooling of the finger chuck body is completed, the collection frame can be directly taken out from the inner wall of the support frame, and the processing status of the finger chuck body can be observed through the transparent observation window during processing. When the processing is completed, the sealing door can be opened, and the placement frame can be moved upward to drive the slag collection frame to separate from the inside of the lifting frame, and the waste slag collected in the slag collection frame can be cleaned out.

[0023] The beneficial effects of the present invention are:

[0024] (1) The present invention can adjust the position of the cutting torch burner in multiple directions when cutting the finger-type chuck body through the mutual cooperation of various components in the adjustable cutting assembly. For example, it can move linearly left and right, up and down, and front and back, so as to facilitate cutting holes at multiple positions on the top of the finger-type chuck body. When it is necessary to cut holes on the outer side of the finger-type chuck body, the cutting torch burner can also be adjusted at multiple angles through the operation of the adjustable cutting assembly. When processing the finger-type chuck body, multi-directional cutting can be achieved to expand the functionality of the entire device.

[0025] (2) The present invention can automatically sense and clamp workpieces of different sizes when cutting the finger-type chuck body by means of the mutual cooperation of the various components in the fixed slag collection assembly, thereby preventing the workpiece from shifting and causing misalignment during the cutting process, thereby improving the accuracy of the cutting process. A lot of waste slag generated during the cutting process can flow downward and be collected in a unified manner to prevent it from splashing around and affecting the working environment.

[0026] (3) The present invention can complete the process of automatic feeding, loading and classified discharging of materials through the mutual cooperation of various components in the automatic feeding and discharging assembly. Since the overall temperature of the finger-type chuck body is very high after cutting, there is a certain safety risk in manual material removal. The setting of the automatic feeding and discharging assembly can avoid such problems. The overall automation level is high, which reduces the manual participation process, and guarantees the processing efficiency and safety to a greater extent during processing.

[0027] (4) The smoke exhaust assembly of the present invention cooperates with each other, and when the cutting torch burner is cutting, a lot of smoke will be generated, which can be fully exhausted and filtered through the smoke exhaust assembly to avoid discomfort caused by long-term inhalation of smoke by workers.

[0028] In summary, the present invention has the advantages of being able to adjust the working position and angle of the cutting torch burner in multiple directions, having stable processing, high precision, practicality and safety, etc. BRIEF DESCRIPTION OF THE DRAWINGS

When the lifting rack 74 rises, it will drive the limit slider 715 to slide upward along the inner wall of the corresponding limit slide groove 716, and rise inside the lifting cavity 717. The lifting rack 74 simultaneously drives the slag collecting frame 55, the placement rack 56 and the finger-type chuck plate body 10 to rise, and then the placement rack 56 is level with the processing table 1, so that the processing table 1 enters the inner cavity of the sealing cover 2;

[0056] S2, clamping process: when the finger-type chuck body 10 is located inside the slag blocking frame 51, the photoelectric sensor 54 senses the finger-type chuck body 10, and then the electric push rod 2 52 pushes the arc-shaped clamping seat 53 to move and clamp the finger-type chuck body 10 to prevent the finger-type chuck body 10 from moving during cutting and causing the problem of cutting misalignment. When the finger-type chuck body 10 is clamped and fixed;

[0057] S3, adjustment process: start the plasma cutting machine 44 to start working, and adjust the position of the cutting torch burner 418 according to the position of the opening of the finger-type chuck plate body 10, and make the electric slider 1 42 move left and right on the electric slide rail 1 41, thereby driving the moving frame 45 and the electric slide rail 2 47 to move, and the electric slide rail 2 47 simultaneously drives the electric push rod 1 410, the moving seat 49, the lifting plate 411, the electric telescopic rod 412, the connecting seat 413, the fixed frame 417 and the cutting torch burner 418 to move. When the cutting torch burner 418 needs to be adjusted, When the electric slider 48 moves forward and backward in the inner wall of the electric slide rail 47, the electric push rod 410, the moving seat 49, the lifting plate 411, the electric telescopic rod 412, the connecting seat 413, the fixing frame 417 and the cutting torch burner 418 are driven to move. The lifting plate 411 is pushed down by the electric push rod 410 to drive the electric telescopic rod 412, the connecting seat 413, the fixing frame 417 and the cutting torch burner 418 to move downward. When the finger chuck body 10 needs to be opened on the side, when the angle of the cutting torch burner 418 needs to be adjusted forward, the movable end of the electric telescopic rod 412 at the front is retracted and the movable end of the electric telescopic rod 412 at the rear is extended, thereby driving the connecting seat 413 to flip forward, and the connecting seat 413 drives the steering seat 415, the fixing frame 417, the connecting seat 419 and the cutting torch burner 418 to flip forward. When the angle of the cutting torch burner 418 needs to be adjusted backward, the connecting seat 413 drives the steering seat 415, the fixing frame 417, the connecting seat 419 and the cutting torch burner 418 to flip forward. The movable end of the electric telescopic rod 412 at the rear is retracted and the movable end of the electric telescopic rod 412 at the front is extended, thereby driving the connecting seat 413 to flip backward, and the connecting seat 413 drives the steering seat 415, the fixing frame 417, the connecting seat 419 and the cutting torch burner 418 to flip backward. When it is necessary to adjust the left and right use angle of the cutting torch burner 418, the reduction motor 416 drives the rotating shaft and the steering seat 415 to rotate on the inner wall of the groove 414, thereby driving the fixing frame 417, the connecting seat 419 and the cutting torch burner 418 to rotate left and right to adjust the angle;

[0058] S4, cutting process: when the finger-type chuck body 10 is cut and opened by the cutting torch burner 418, a lot of waste slag will be generated and fall into the slag collecting frame 55 through the placement rack 56 for unified collection, and the slag blocking rack 51 can prevent the waste slag from splashing during the processing. At the same time, when the plasma cutting machine 44 is working, the driving motor 33 is started to drive the smoke exhaust fan 34 to rotate on the annular rack 35, and the smoke generated during the processing is filtered through the smoke filter 32 from the sealing cover 2 and discharged through the smoke outlet 31;

[0059] S5, discharging process: after the processing of the finger-type chuck disc body 10 is completed, the movable end of the lifting push rod 72 contracts to drive the lifting seat 73 and the lifting frame 74 to descend. When the lifting frame 74 descends, it will drive the limit slider 715 to slide downward along the inner wall of the corresponding limit slide groove 716. The lifting frame 74 simultaneously drives the slag collecting frame 55, the placement frame 56 and the finger-type chuck disc body 10 to descend, and then the placement frame 56 and the finger-type chuck disc body 10 horizontally through the inner wall of the opening 75 enter the lifting chamber 717. When processing two finger-type chuck disc bodies 10 of different specifications, the feed push rod 77 continuously pushes the feed push plate 78 to the lifting chamber 717. The finger-shaped chuck disc 10 that has been processed on the top wall of the placement rack 56 is moved inside the descending chamber 717, and the finger-shaped chuck disc 10 that has been processed on the top wall of the placement rack 56 is pushed to the right through-port 75, and then falls into the collection frame 711 through the corresponding inclined groove 79 for cooling. The finger-shaped chuck disc 10 of another specification can be pushed to the through-port 75 at the rear by the discharge push rod 713, and the discharge push plate 714 can slide into the collection frame 711 at the rear through the inclined groove 79 for unified collection. The finger-shaped chuck discs 10 of different specifications can be placed in batches to prevent mixing and avoid subsequent sorting.

[0060] S6. Cooling process: Since the temperature of the finger-type chuck body 10 is very high just after cutting, when it is placed in the collecting frame 711, a fan can be placed at a position corresponding to the collecting frame 711 outside the entire device to accelerate the cooling time of the finger-type chuck body 10. When the finger-type chuck body 10 is cooled, the collecting frame 711 can be directly taken out from the inner wall of the support frame 710, and the processing status of the finger-type chuck body 10 can be observed through the transparent observation window 9 during processing. When the processing is completed, the sealing door 8 can be opened, and the placement frame 56 can be moved upward to drive the slag collecting frame 55 to separate from the inside of the lifting frame 74, and the waste slag collected in the slag collecting frame 55 can be cleaned out.

[0061] Working principle: First, the smoke filter 32, the drive motor 33, the electric slide rail 1 41, the electric slider 1 42, the plasma cutter 44, the electric slide rail 2 47, the electric slider 2 48, the electric push rod 1 410, the electric telescopic rod 412, the reduction motor 416, the electric push rod 2 52, the photoelectric sensor 54, the lifting push rod 72, the feed push rod 77, and the discharge push rod 713 are electrically connected through the external power supply and the PLC controller 6. When the finger-type chuck body 10 is subjected to the hole cutting process, the finger-type chuck body 10 is first placed into the inner wall of the feed rack 76, and the feed push plate 78 is pushed by the feed push rod 77 to move, and the finger-type chuck body 10 is pushed away from the inner wall of the feed rack 76 through the through hole 75 on the left side and then pushed to the middle of the top wall of the placement rack 56. When the limit slider 715 is located at the bottom of the inner wall of the corresponding limit slide groove 716, the placement rack 56 is horizontal with the through hole 75. When the limit slider 715 is located at the top of the inner wall of the corresponding limit slide groove 716, the placement rack 56 is horizontal with the top wall of the processing table 1. The movable end of the lifting push rod 72 installed in the installation cavity 71 pushes the lifting seat 73 and the lifting rack 74 to rise. When the lifting rack 74 rises, it will drive the limit slider 715 to slide upward along the inner wall of the corresponding limit slide groove 716 and rise inside the lifting cavity 717. The lifting rack 74 simultaneously drives the slag collecting frame 55, the placement rack 56 and the finger-type chuck disc body 10 to rise, so that the placement rack 56 is horizontal with the processing table 1, so that the processing table 1 enters the inner cavity of the sealing cover 2. When the chuck body 10 is located inside the slag blocking frame 51, the photoelectric sensor 54 senses the finger-type chuck body 10, and then the arc-shaped clamping seat 53 is pushed by the electric push rod 2 52 to move and clamp the finger-type chuck body 10 to prevent the finger-type chuck body 10 from moving during cutting and causing cutting misalignment. After the finger-type chuck body 10 is clamped and fixed, the plasma cutting machine 44 is started to work, and the position of the cutting torch burner 418 is adjusted according to the opening position of the finger-type chuck body 10. The electric slider 1 42 performs a left and right linear motion on the electric slide rail 1 41, thereby driving the moving frame 45 and the electric slide rail 2 47 to move. The electric slide rail 2 47 simultaneously drives the electric push rod 1 410, the moving seat 49, the lifting plate 411, The electric telescopic rod 412, the connecting seat 413, the fixing frame 417 and the cutting torch burner 418 are movable. When the cutting torch burner 418 needs to be adjusted to move forward and backward, the electric slider 48 moves linearly forward and backward in the inner wall of the electric slide rail 47, thereby driving the electric push rod 1 410, the moving seat 49, the lifting plate 411, the electric telescopic rod 412, the connecting seat 413, the fixing frame 417 and the cutting torch burner 418 to move. The lifting plate 411 is pushed down by the electric push rod 1 410 to drive the electric telescopic rod 412, the connecting seat 413, the fixing frame 417 and the cutting torch burner 418 to move downward, and the top of the finger-type chuck body 10 is cut and opened under the cooperation of the plasma cutting machine 44, the connecting seat 419 and the cutting torch burner 418.When it is necessary to drill a hole on the side of the finger-type chuck body 10, when it is necessary to adjust the angle of the cutting torch burner 418 forward, the movable end of the electric telescopic rod 412 located at the front is retracted and the movable end of the electric telescopic rod 412 located at the rear is extended, thereby driving the connecting seat 413 to flip forward, and the connecting seat 413 drives the steering seat 415, the fixing frame 417, the connecting seat 419 and the cutting torch burner 418 to flip forward. When it is necessary to adjust the angle of the cutting torch burner 418 backward, the movable end of the electric telescopic rod 412 located at the rear is retracted and the movable end of the electric telescopic rod 412 located at the front is extended, thereby driving the connecting seat 413 to flip backward, and the connecting seat 413 drives the steering seat 415, the fixing frame 417, the connecting seat 419 and the cutting torch burner 418 to After flipping, when it is necessary to adjust the angle of use of the cutting torch burner 418 to the left or right, the reduction motor 416 drives the rotating shaft and the steering seat 415 to rotate on the inner wall of the groove 414, thereby driving the fixing frame 417, the connecting seat 419 and the cutting torch burner 418 to rotate left and right to adjust the angle. When the finger-type chuck disc body 10 is cut and opened by the cutting torch burner 418, a lot of waste slag will be generated through the placement rack 56 and fall into the slag collecting frame 55 for unified collection, and the slag blocking rack 51 can prevent the waste slag from splashing during the processing. At the same time, when the plasma cutting machine 44 is working, the driving motor 33 is started to drive the smoke exhaust fan 34 to rotate on the annular frame 35, and the smoke generated during the processing is filtered from the sealing cover 2 through the smoke filter 32. After being processed, it is discharged through the smoke outlet 31. When the finger-type chuck disc body 10 is processed, the movable end of the lifting push rod 72 contracts to drive the lifting seat 73 and the lifting frame 74 to descend. When the lifting frame 74 descends, it will drive the limiting slider 715 to slide downward along the inner wall of the corresponding limiting slide groove 716. The lifting frame 74 simultaneously drives the slag collecting frame 55, the placement frame 56 and the finger-type chuck disc body 10 to descend, and then the placement frame 56 and the finger-type chuck disc body 10 horizontally through the inner wall of the opening 75 enter the lifting chamber 717. When processing two finger-type chuck disc bodies 10 of different specifications, the feed push rod 77 continuously pushes the feed push plate 78 to move into the inside of the lifting chamber 717, and the finger-type chuck disc body 10 that has been processed on the top wall of the placement frame 56 is moved. After being pushed to the right through port 75, the finger chuck body 10 passes through the corresponding inclined slot 79 and falls into the collection frame 711 for cooling. The finger chuck body 10 of another specification can be pushed to the through port 75 at the rear through the discharging push rod 713 and the discharging push plate 714 to push the finger chuck body 10 processed on the top of the placement rack 56 to the through port 75 at the rear and slide through the inclined slot 79 to the collection frame 711 at the rear for unified collection. The finger chuck bodies 10 of different specifications can be placed in batches to prevent mixing and avoid subsequent sorting. Since the temperature of the finger chuck body 10 just after cutting is very high, when it is placed in the collection frame 711, a fan can be placed at the position corresponding to the collection frame 711 outside the entire device to accelerate the cooling time of the finger chuck body 10.When the finger-type chuck body 10 is cooled, the collection frame 711 can be directly taken out from the inner wall of the support frame 710, and the processing of the finger-type chuck body 10 can be observed through the transparent observation window 9. When the processing is completed, the sealing door 8 can be opened, and the placement frame 56 can be moved upward to drive the slag collection frame 55 out of the lifting frame 74, and the waste slag collected in the slag collection frame 55 can be cleaned out.
