DETAILED DESCRIPTION

[0016] See Figures 1-10 An adjustable eccentric spiral milling device includes a workbench 1, a movable table 4 is installed on the upper side of the workbench 1, a motor 2 is fixedly connected to the upper side of the workbench 1, and a thread cutter 3 is installed on the outer side of the output shaft of the motor 2; First, a control system that can adjust the position of the movable table 4 is installed on the upper side of the workbench 1, which mainly includes a horizontal slide, a vertical slide, a threaded rod, etc. When an eccentric screw needs to be processed, a suitable thread cutter 3 is first selected and the thread cutter 3 is installed on the output end of the motor 2. The object to be processed is placed on the movable table 4, and the position of the movable table 4 is adjusted by the control system, thereby adjusting the position of the object to be processed. Then, the workbench 1 and the motor 2 are started, and while the motor 2 is driven to move downward, the output shaft of the motor 2 drives the thread cutter 3 to rotate, and then the corresponding processing operation is started. The above are all existing technologies and no unnecessary details are given. Two clamping plates 12 are slidably connected to the moving platform 4, and the clamping plate 12 is fixedly connected to the arc plate 13. The moving platform 4 is slidably installed with an intermediate frame 19 through a protective assembly. The intermediate frame 19 rotates and passes through a center rod 15. The protective assembly includes two baffles 17. The center rod 15 is fixedly connected to a gear 20. The two clamping plates 12 are fixedly connected to a fixed rod 22. The fixed rod 22 is fixedly connected to a rack 21. The rack 21 and the intermediate frame 19 are slidably connected. The rack 21 and the gear 20 are meshed. The fixed rod 22 is slidably connected to a slide plate 23. The clamping plate 12 is fixedly connected to a fixed plate 25. A first spring 24 is fixedly connected between the slide plate 23 and the fixed plate 25. The slide plate 23 is fixedly connected to two connecting rods 26. The connecting rod 26 is slidably connected to a slide rail 31. The slide rail 31 is fixedly connected to a limit plate 30. The limit plate 30 is fixedly connected to the baffle 17. A fifth spring 41 is fixedly connected between the baffle 17 and the clamping plate 12. The movable assembly is installed on the upper side of the movable platform 4. The movable assembly includes a rotating rod 5 that rotates and runs through the movable platform 4. The outer side of the rotating rod 5 is fixedly connected to two threaded cylinders 7. The outer sides of the two threaded cylinders 7 are threadedly connected to threaded rings 8. The threaded ring 8 and the movable platform 4 are slidably connected. The threaded ring 8 and the clamping plate 12 are fixedly connected. An opening is opened on the lower side of the movable platform 4. The lower side of the threaded ring 8 is fixedly connected to a cleaning plate 9. The cleaning plate 9 and the movable platform 4 are slidably connected. A plurality of isolation plates 14 are evenly fixedly connected to the upper side of the movable platform 4. The upper side of the threaded ring 8 is fixedly connected to a cleaning rod 11. The cleaning rod 11 and the isolation plate 14 are staggered. The cleaning rod 11 and the clamping plate 12 are fixedly connected. The outer side of the center rod 15 is fixedly connected to a fixing ring 27. The outer side of the center rod 15 is slidably connected to a pressing cylinder 29. A second spring 28 is fixedly connected between the pressing cylinder 29 and the fixing ring 27. Both ends of the rotating rod 5 are fixedly connected to a turntable 6, and the outer side of the turntable 6 is fixedly connected to a rotating rod; First, in the initial state, the center rod 15 and the output shaft of the motor 2 are in a concentric state. The object to be processed is placed between the two clamping plates 12, and the rotating rod 5 is rotated. Since the outer threads of the threaded barrels 7 on both sides are rotated in opposite directions, and the cleaning plate 9 and the moving platform 4 on the lower side of the threaded ring 8 are in sliding connection, the rotating threaded barrel 7 will drive the clamping plate 12 and the curved plate 13 to move toward each other through the cleaning rod 11 until the curved plate 13 and the object to be processed are at odds with each other, thereby completing the clamping and fixing operation of the object to be processed, and in this process, the moving clamping plate 12 drives the fixing rod 22 to move toward each other, and the fixing rod 22 drives the rack 21 to move The two racks 21 are respectively located on both sides of the gear 20. Although the relative movement of the racks 21 will cause the gear 20 to rotate, the forces exerted by the two racks 21 on the gear 20 are equal in magnitude and opposite in direction. Moreover, under the action of the fifth spring 41, the center rod 15 is always at the center of the circle of the object to be detected. When the position of the movable platform 4 is adjusted, the center rod 15 is always at the center of the circle of the object to be processed, which can play a certain reminder effect. In addition, during the processing, the baffle 17 is located on both sides of the eccentric spiral hole to be processed. Most of the debris generated is offset by the baffle 17. Under the obstruction of the baffle 17, the possibility of debris flying around is reduced, achieving multiple goals at one stroke. During the processing, most of the cooling water and debris will eventually fall into the movable table 4. After the processing is completed, under the action of the cleaning rod 11 and the cleaning plate 9, a simple cleaning effect will be formed on the upper isolation plate 14 of the movable table 4 and the interior of the movable table 4, so that the cooling water and debris inside the movable table 4 will eventually be discharged through the through hole, maintaining the cleanliness of the entire device. After the object to be processed is placed between the two clamping plates 12, the pressing cylinder 29 is located directly above the center of the object to be processed and is against the object to be processed, and the second spring

[31] 28 is in a compressed state.

[0017] The connecting rod 26 is located in the slide rail 31 and is fixedly connected to the slider 42. The side wall of the slider 42 is fixedly connected to the connecting plate 43. A rotating groove 49 is opened on the lower side of the baffle 17. The connecting plate 43 is located in the rotating groove 49 and is fixedly connected to the connecting ring 44. A transmission rod 45 is rotatably connected in the rotating groove 49. A fixed cylinder 46 is fixedly connected to the outer side of the transmission rod 45. The connecting ring 44 and the fixed cylinder 46 are threadedly connected. A plurality of rotating rods 48 are also rotatably connected in the rotating groove 49. Each rotating rod 48 is connected to the transmission rod 45 through a pulley assembly 47. A plurality of rotating plates 50 are fixedly connected to the outer side of each rotating rod 48. First, when the connecting rod 26 moves relative to the slide rail 31, specifically, before and after the milling hole, the connecting rod 26 drives the connecting ring 44 to move through the slider 42 and the connecting plate 43. Since the connecting ring 44 and the fixed cylinder 46 are threadedly connected, and the threads on the outside of the fixed cylinder 46 and the rotating rod 5 are roughly the same shape as the two threaded cylinders 7, that is, the threads on both sides of the fixed cylinder 46 have opposite rotation directions, the moving fixed cylinder 46 will drive the fixed cylinder 46 and the transmission rod 45 to rotate, and the transmission rod 45 drives the rotating rod 48 to rotate through the pulley assembly 47, and the rotating rod 48 drives the rotating plate 50 to rotate. During this process, the rotating plate 50 is located on the upper side of the object to be processed, and the generated debris may fall on the upper side of the object to be processed. Therefore, under the action of the rotating plate 50, the rotating rotating plate 50 will cause the debris to move, so that the debris moves into the movable table 4, thereby achieving a simple self-cleaning effect.

[0018] A friction cleaning assembly is installed on the side wall of the baffle 17. The friction cleaning assembly includes two moving rods 33 that slide through the baffle 17. One end of the two moving rods 33 is fixedly connected to the moving plate 18. A third spring 32 is fixedly connected between the moving plate 18 and the baffle 17. The other ends of the two moving rods 33 are fixedly connected to a control plate 34. The lower side of the control plate 34 is slidably connected to a connecting plate. The lower side of the connecting plate is slidably connected to a friction plate 36. A fourth spring 35 is fixedly connected between the friction plate 36 and the connecting plate. The side walls of the two moving rods 33 are fixedly connected to switch rods 37. First, the two switch rods 37 are similar to touch switches in real life, and the two switch rods 37 are connected to the workbench 1 through wires. The two switch rods 37 are equivalent to the two levels of the touch switch. When the two switch rods are against each other, the circuit composed of the switch rods 37, the wires, and the workbench 1 will be closed, and the workbench 1 will send a corresponding signal to remind the staff. Then, when the processing starts, that is, when the motor 2 moves downward, when the thread cutter 3 is about to be against the object to be processed, the motor 2 first is against the trapezoidal plate 16, which will form a squeezing effect on the trapezoidal plate 16, thereby causing the trapezoidal plate 16 to move away from the baffle 17. The trapezoidal plate 16 drives the control plate 34 to move through the moving rod 33 and the moving plate 18, and the control plate 34 drives the friction plate 36 to move. The friction plate 36 can form a wiping effect on the object to be processed, so as to keep the object to be processed clean. After the processing is completed, when the motor 2 returns to its original position, under the action of the third spring 32, the trapezoidal plate 16 as a whole returns to its original position relative to the baffle 17. During this process, the friction plate 36 will also move with the control plate 34. During this process, if burrs, rough edges, etc. are generated on the outside of the object to be processed, the friction plate 36 cannot return to its original position, and the two switch rods 37 do not offset each other, which can play a certain reminder effect.

[0019] The side wall of the friction plate 36 is fixedly connected to an extension rod 38. The lower side of each baffle 17 is provided with a wave groove 39. A slide rod 40 is slidably connected in the wave groove 39. The slide rod 40 is fixedly connected to the extension rod 38. First, Figure 9 The fourth spring 35 is fixedly connected between the connecting plate and the friction plate 36, and the connecting plate and the friction plate 36 are connected for up and down sliding movement. Secondly, when the friction plate 36 moves following the movement of the control plate 34, under the restriction of the wave groove 39 and the slide bar 40, the friction plate 36 will move relative to the control plate 34. Under the action of the fourth spring 35, the friction plate 36 is always against the object to be processed. The friction plate 36 moving back and forth can not only rub and clean the object to be processed, but also squeeze and knock the burrs to a certain extent, thereby forming a simple treatment for the burrs.

[0020] In the present invention, when an eccentric screw needs to be processed, a suitable thread cutter 3 is first selected and installed on the output shaft of the motor 2. The object to be processed is first placed on the movable table 4, and the turntable 6 is rotated, thereby driving the thread ring 8 to move toward each other. The thread ring 8 drives the clamping plate 12 and the curved plate 13 to move through the first connecting rod 10 and the cleaning rod 11 until the curved plate 13 and the object to be processed are in contact with each other, thereby completing the clamping and fixing operation of the object to be processed. During the above working process, the moving clamping plate 12 drives the fixed rod 22 to move toward each other, and the fixed rod 22 drives the rack 21 to move. Under the action of the fifth spring 41, the center rod 15 is always at the center of the object to be inspected, and the pressing cylinder 29 is located on the upper side of the object to be processed and abuts against the object to be processed. Then, according to the processing position, the position of the movable table is adjusted until the processing position and the thread cutter 3 are opposite. During this process, the center rod 15 is always at the center of the object to be processed, which can play a certain reminder effect. The workbench 1 and the motor 2 are started, and while the motor 2 is driven to move downward, the output shaft of the motor 2 drives the thread cutter 3 to rotate. The thread cutter 3 enters the object to be processed and begins the milling operation. During the processing, the baffles 17 are located on both sides of the eccentric spiral hole to be processed. Most of the generated debris is offset by the baffles 17. Under the blocking effect of the baffles 17, the possibility of debris flying around is reduced; During this process, when the thread cutter 3 is about to come into contact with the object to be processed, the motor 2 first comes into contact with the trapezoidal plate 16, which creates a squeezing effect on the trapezoidal plate 16, thereby causing the trapezoidal plate 16 to move away from the baffle 17. The trapezoidal plate 16 drives the control plate 34 to move, and the control plate 34 drives the friction plate 36 to move. The friction plate 36 can form a wiping effect on the object to be processed, thereby keeping the object to be processed clean. After the milling operation is completed, the workbench 1 and the motor 2 are turned off, and the motor 2 returns to its original position relative to the workbench 1. During this process, the trapezoidal plate 16 loses the squeezing effect of the motor 2, and under the action of the third spring 32, the trapezoidal plate 16, the movable plate 18 and the movable rod 33 return to their original positions relative to the baffle 17. During this process, if burrs or rough edges are generated on the outer side of the object to be processed, the friction plate 36 cannot return to its original position, and the two switch rods 37 do not contact each other, which can play a certain reminder effect. At the same time, under the restriction of the wave groove 39 and the slide bar 40, the friction plate 36 will move relative to the control plate 34. The friction plate 36 moving back and forth can not only rub and clean the workpiece, but also squeeze and knock the burrs to a certain extent, thus forming a simple treatment for the burrs. After the processing is completed, the turntable 6 is rotated again to take out the processed object, thereby completing the processing operation of the eccentric screw as a whole and installing the thread cutter 3 on the output end of the motor 2. The object to be processed is placed on the movable table 4, and the position of the movable table 4 is adjusted by the control system to adjust the position of the object to be processed. Then, the workbench 1 and the motor 2 are started, and while the motor 2 is driven to move downward, the output shaft of the motor 2 drives the thread cutter 3 to rotate, and then the corresponding processing operation is started. The above are all existing technologies and no redundant description is made. In the initial state, the center rod 15 and the output shaft of the motor 2 are in a concentric state. The object to be processed is placed between the two clamping plates 12, and the rotating rod 5 is rotated. Since the outer threads of the threaded barrels 7 on both sides rotate in opposite directions, and the cleaning plate 9 and the moving platform 4 on the lower side of the threaded ring 8 are in sliding connection, the rotating threaded barrel 7 will drive the clamping plates 12 and the curved plates 13 to move toward each other through the cleaning rod 11 until the curved plates 13 and the object to be processed are at odds with each other, thereby completing the clamping and fixing operation of the object to be processed. In this process, the moving clamping plates 12 drive the fixing rods 22 to move toward each other, and the fixing rods 22 drive the rack 21 to move. The two racks 21 are respectively located on either side of the gear 20. Although the relative movement of the racks 21 causes the gear 20 to rotate, the forces exerted on the gear 20 by the two racks 21 are equal in magnitude and opposite in direction. Furthermore, under the action of the fifth spring 41, the center rod 15 is always located at the center of the object to be detected. When the position of the movable platform 4 is adjusted, the center rod 15 is always located at the center of the object to be processed, thereby providing a certain reminder effect. In addition, during the processing, the baffles 17 are located on both sides of the eccentric spiral hole to be processed, and most of the generated debris is offset by the baffles 17. Under the obstruction of the baffles 17, the possibility of debris flying around is reduced, achieving multiple goals at one stroke. During the processing, most of the cooling water and debris will eventually fall into the movable table 4. After the processing is completed, under the action of the cleaning rod 11 and the cleaning plate 9, a simple cleaning effect will be formed on the upper isolation plate 14 of the movable table 4 and the interior of the movable table 4, so that the cooling water and debris inside the movable table 4 will eventually be discharged through the through hole, maintaining the cleanliness of the entire device. After the object to be processed is placed between the two clamping plates 12, the pressing cylinder 29 is located directly above the center of the object to be processed and abuts against the object to be processed, and the second spring is in a compressed state; When the machining starts, that is, when the motor 2 moves downward, when the thread cutter 3 is about to collide with the object to be machined, the motor 2 first collide with the trapezoidal plate 16, which will form a squeezing effect on the trapezoidal plate 16, thereby causing the trapezoidal plate 16 to move in the direction away from the baffle 17, and the trapezoidal plate 16 drives the control plate 34 to move through the moving rod 33 and the moving plate 18, and the control plate 34 drives the friction plate 36 to move, and the friction plate 36 can form a wiping effect on the object to be machined, keeping the object to be machined clean. And when the machining is completed, when the motor 2 returns to its original position, under the action of the third spring 32, the trapezoidal plate 16 as a whole returns to its original position relative to the baffle 17. In this process, the friction plate 36 will also move with the control plate 34. In this process, if burrs, burrs, etc. are generated on the outer side of the object to be machined, the friction plate 36 cannot return to its original position, and the two switch rods 37 do not collide with each other, which can play a certain reminder effect. When the friction plate 36 moves following the control plate 34, under the restriction of the wave groove 39 and the slide bar 40, the friction plate 36 will move relative to the control plate 34. Under the action of the fourth spring 35, the friction plate 36 is always in contact with the object to be processed. The friction plate 36 moving back and forth can not only rub and clean the object to be processed, but also squeeze and knock the burrs produced to a certain extent, forming a simple treatment of the burrs.
