Description

Technical Field

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

[0002] The finger chuck is a common fixture, mainly used for clamping workpieces in mechanical processing. Its working principle is to clamp and position the workpiece by utilizing the radial movement of movable jaws evenly distributed on the chuck body. 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 the cutting process. When the cutting is completed, the temperature of the chuck body is very high and it needs to wait for it to cool down before it can be removed.

[0003] Chinese Patent Publication No. CN221695306U discloses a drilling device for producing chucks for CNC machine tools, comprising a housing, a mounting seat being slidably connected to the top of the housing, a cylinder being fixedly mounted on the front side of the mounting seat, an L-shaped mounting plate being fixedly connected to the output end of the cylinder, the L-shaped mounting plate sliding on the front side of the mounting seat, and a drilling device being mounted on the bottom of the L-shaped mounting plate. The utility model uses the drilling device to drill a hole in the chuck, and then aligns a universal water spray head with the drill bit of the drilling device to flush out debris. After simple filtration through a filter plate, large particles of debris remain on the surface of the filter plate, while fine debris and cutting fluid enter the inner cavity of a cylindrical filter cartridge for filtration. Gravity causes the debris to settle into the inner cavity of a settling hopper, and the filtered cutting fluid enters the inner cavity of a cutting fluid recovery chamber. The debris is recovered by withdrawing the filter plate and opening a valve at the bottom of the settling hopper, thereby facilitating the collection of debris and recycling the cutting fluid.

[0004] Regarding the above-mentioned related technologies: When cutting the disc 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 disc body of the finger-type chuck will also be drilled. 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 disc body after cutting is very high, it is not convenient to adjust the position. Therefore, multi-directional cutting can avoid this problem.

[0016] An arc cutting process for producing a finger 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 in the inner wall of the feed rack, and the feed push rod pushes the feed push plate to move, pushes the finger-type chuck disc body away from the inner wall of the feed rack, passes through the through-hole on the left, and is pushed to the position of the middle of the top wall of the placement rack. When the limit slider is at the bottom of the inner wall of the corresponding limit slide groove, the placement rack is level with the through-hole, and when the limit slider is 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, and the movable end of the lifting push rod installed in the installation cavity pushes the lifting seat and the lifting rack to rise. 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, and then 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 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 work, 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 movable frame and the electric slide rail 2 to move, and the electric slide rail 2 simultaneously drives the electric push rod 1, the movable 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 position of the cutting torch burner to move forward and backward, the electric slider 2 moves forward and backward in the inner wall of the electric slide rail 2, thereby driving the electric push rod 1, the movable 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 to move downward, driving 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 finger-type chuck is used to cut a hole at the top of the disc body. When a hole needs to be drilled on the side of the disc body, 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 fixing 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 fixing frame, the connecting seat and the cutting torch burner to flip backward. When the left and right use angle of the cutting torch burner needs 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 fixing frame, the connecting seat and the cutting torch burner to rotate left and right to adjust the angle.

[0020] S4. Cutting process: When the cutting torch burner is used to cut and open a hole in the finger-type chuck, a lot of waste slag will be generated and fall into the slag collecting frame through the placement rack for unified collection. 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 ring 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] 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 processed on the top of the placing rack to the through-port at the rear and slide through the inclined slot to the inside of the collection frame at the rear for unified collection. 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 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. When the finger chuck body is cooled, 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 out of the inside of the lifting frame to clean out the waste slag collected in the slag collection frame.

[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. Moreover, 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, thereby expanding 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 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, improving the accuracy of the cutting process, and a lot of waste slag generated during the cutting process can 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 sorting out of materials through the mutual cooperation of various components in the automatic feeding and unloading 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 unloading assembly can avoid such problems. The overall degree of automation is high, which reduces the manual participation process and guarantees the processing efficiency and safety to a greater extent during processing.

[0027] (4) The present invention uses the mutual cooperation of various components in the smoke exhaust assembly. When the cutting torch burner generates a lot of smoke during cutting, the smoke exhaust assembly can fully exhaust and filter the smoke, thus avoiding discomfort caused by long-term inhalation of smoke by workers.

[0028] In summary, the present invention has the advantages of multi-directional adjustment of the working position and angle of the cutting torch burner, stable processing, high precision, practicality and safety, etc. BRIEF DESCRIPTION OF THE DRAWINGS

[0054] An arc cutting process for producing a finger chuck comprises the following steps:

[0055] S1, loading process: when the finger-type chuck disc body 10 is subjected to the hole cutting process, the finger-type chuck disc body 10 is first placed into the inner wall of the feed rack 76, and the feed push rod 77 pushes the feed push plate 78 to move, and the finger-type chuck disc 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 position of the middle of the top wall of the placement rack 56.

[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 the electric push rod 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 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 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. The electric slide rail 2 47 also 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 2 48 moves forward and backward in the inner wall of the electric slide rail 2 47, 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 driven 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. The top of the finger-type chuck body 10 is cut and opened during the working process. When a hole is needed on the side of the finger-type chuck body 10, 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. 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. By retracting the movable end of the electric telescopic rod 412 at the rear, 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 cutting torch burner 418 to the left or right using angle, 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 or 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 is generated and falls into the slag collecting frame 55 through the placement rack 56 for unified collection. 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 drive 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 through the smoke filter 32 from the sealing cover 2 and discharged through the smoke outlet 31;

[0059] S5, discharging process: when the processing of the finger-type chuck disc 10 is completed, the movable end of the lifting push rod 72 contracts and drives the lifting seat 73 and the lifting frame 74 to descend. When the lifting frame 74 descends, it drives 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 10 to descend, and then the placement frame 56 and the finger-type chuck disc 10 are horizontally moved into the lifting chamber 717 through the inner wall of the through-hole 75. When processing two finger-type chuck discs 10 of different specifications, the feed push plate 78 is continuously pushed to the lifting position by the feed push rod 77. The lowering chamber 717 moves inside to push the finger-shaped chuck disc 10 that has been processed on the top wall of the placement rack 56 to the through-port 75 on the right, 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 by the discharge push rod 713 to push the discharge push plate 714 to push the finger-shaped chuck disc 10 that has been processed on the top of the placement rack 56 to the through-port 75 at the rear, and slide through the inclined groove 79 to the collection frame 711 at the rear 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 chuck body 10 is very high after cutting, when it is placed in the collection frame 711, a fan can be placed at a 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 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 status of the finger 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 out of the interior of the lifting frame 74 to clean out the waste slag collected in the slag collecting frame 55.

[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 disc 10 is subjected to the hole-cutting processing, the finger-type chuck disc 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 disc 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 locking chuck 715 is in the locked state, the locking chuck 715 will be in the locked state again, and the locking chuck 715 will be in the locked state again, so that the locking chuck 715 can be locked again. When the chuck disc body 10 is located inside the slag blocking frame 51, the photoelectric sensor 54 senses the finger-type chuck disc 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 disc body 10 to prevent the finger-type chuck disc body 10 from moving during cutting and causing the problem of cutting misalignment. After the finger-type chuck disc 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 disc 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 position of the cutting torch burner 418 needs to be adjusted forward and backward, the electric slider 2 48 moves linearly forward and backward in the inner wall of the electric slide rail 2 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 electric push rod 1 410 pushes the lifting plate 411 to move downward, driving 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 chuck disc 10 is cut and opened under the mutual 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 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 and collected uniformly. 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 drive 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 and drives the lifting seat 73 and the lifting frame 74 to descend. When the lifting frame 74 descends, it drives 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 are horizontally moved into the lifting chamber 717 with the inner wall of the through-port 75. 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 interior 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, it passes through the corresponding inclined slot 79 and falls into the interior of the collection frame 711 for cooling. The finger-type chuck disc 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-type chuck disc 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 interior of the collection frame 711 at the rear for unified collection. The finger-type chuck discs 10 of different specifications can be placed in batches to prevent mixing and avoid subsequent sorting. Since the temperature of the finger-type chuck disc 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-type chuck disc 10.After the finger chuck body 10 has cooled, the collection frame 711 can be directly removed from the inner wall of the support frame 710. During processing, the processing status of the finger chuck body 10 can be observed through the transparent observation window 9. When 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 interior of the lifting frame 74, and the waste slag collected in the slag collection frame 55 can be cleaned out.
