Description

Technical Field

[0001] The invention relates to the technical field of rust removal, in particular to a surface rust removal device for a marine pipeline support. Background Art

[0002] Pipe brackets are mainly used to fix pipelines with oil, water and gas as media in mechanical hydraulic systems such as ships and electricity. Marine pipe brackets are installed on ships, so they need to have a certain degree of corrosion resistance. Therefore, it is necessary to remove the rust on their surface before installation and restore their metal color to facilitate subsequent anti-corrosion coating or maintenance work.

[0003] However, the U-shaped pipe bracket is divided into an arc section and a straight section. The existing rust removal method is generally handled manually, which is difficult to fit the surface of the arc section, and the rust removal effect cannot be guaranteed. Summary of the invention

[0004] The object of the present invention is to provide a surface rust removal device for a marine pipeline support to solve the problems raised in the prior art.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: The present invention provides a technical solution for a surface rust removal device for a marine pipeline bracket, the surface rust removal device comprising a workbench, a movable component, a clamping component, a rust removal component and an adjustment component, the movable component is tightly connected to the workbench, the clamping component is tightly connected to the workbench, the rust removal component is tightly connected to the movable component, the adjustment component is tightly connected to the rust removal component, and the adjustment component is used to adjust the state of the rust removal component.

[0006] The present invention is used for removing rust from a U-shaped pipeline support, and the U-shaped pipeline support is divided into an arc segment and a straight segment. The existing rust removal method is generally processed manually, which is difficult to fit the surface of the arc segment, and the rust removal effect cannot be guaranteed; the workbench is used to provide stable support for each component. During the rust removal operation, the workpiece to be processed is first placed on the workbench, and then the clamping component is started to fix the workpiece, and the rust removal component is driven by the movable component to sweep across the surface of the workpiece to remove rust from the workpiece. When the rust removal component passes through the arc segment of the workpiece, the shape of the rust removal component is adjusted by the adjusting component to make it fit the surface of the workpiece, thereby ensuring the rust removal effect.

[0007] Furthermore, the rust removal component includes a flexible layer, a grinding ring and a detection element. The flexible layer is tightly connected to the adjustment component, the grinding ring is tightly connected to the flexible layer, the cross-section of the grinding ring is an inverted trapezoid, and several grinding rings are arranged along the inner wall of the flexible layer. The detection element is tightly connected to the flexible layer, and the detection element is used to detect the curvature of the workpiece.

[0008] The flexible layer is in the shape of a circular tube, and the diameter of the flexible layer matches the diameter of the workpiece. When removing rust, the workpiece is inserted into the flexible layer. When the rust removal component sweeps across the surface of the workpiece driven by the movable component, when the rust removal component passes through the straight section of the workpiece, the detection element does not move, and the grinding ring on the inner wall of the flexible layer abuts against the surface of the workpiece for processing. When the rust removal component passes through the arc section of the workpiece, the detection element moves and determines the curvature of the arc section. Then, the shape of the flexible layer is changed by adjusting the component to match the shape of the flexible layer with the shape of the arc section, so that the grinding ring fits the surface of the workpiece. The inverted trapezoidal grinding ring can facilitate the change of the shape of the flexible layer, thereby performing rust removal on the arc section of the workpiece without dead angles, thereby improving the rust removal effect.

[0009] Furthermore, the adjustment component includes a support ring, a first adjustment member, a second adjustment member, an upper support rod, a lower support rod and a support spring. The support ring is tightly connected to the movable member, one end of the first adjustment member is hinged to the support ring, the other end of the first adjustment member is hinged to the flexible layer, one end of the second adjustment member is hinged to the support ring, the other end of the second adjustment member is hinged to the flexible layer, an upper chamber and a lower chamber are provided in the support ring, the upper support rod is slidably connected to the upper chamber, the upper support rod is tightly connected to the flexible layer, the lower support rod is slidably connected to the lower chamber, the lower support rod is tightly connected to the flexible layer, and the support spring is sleeved on the upper support rod and the lower support rod.

[0010] The support ring is fixed on the movable component to provide support for the rust removal component. The upper support rod and the lower support rod are respectively fixed at the upper and lower ends of the flexible layer to provide support for it. The first adjusting member is located above the support ring, and the second adjusting member is located below the support ring. When the rust removal component passes through the arc section of the workpiece, the first adjusting member expands to both sides and the second adjusting member contracts inward, so that the shape of the flexible layer is changed into an arc shape, thereby fitting the surface of the workpiece. When the first adjusting member expands to both sides, it can drive the upper support rod to move upward along the upper chamber. When the second adjusting member contracts inward, it can drive the lower support rod to move upward along the lower chamber, forming a three-point support for the flexible layer to maintain the stability of the deformed flexible layer.

[0011] Further, the first adjusting member includes a first sleeve and a first piston, the first piston is slidably connected to the first sleeve, the first sleeve is hinged to the support ring, the first piston is hinged to the flexible layer, the inner cavity of the first sleeve is divided into chamber a and chamber b by the first piston, chamber a is communicated with the upper chamber, and chamber a is located on a side of the first sleeve away from the support ring; The second adjusting member includes a second sleeve and a second piston, the second piston is slidably connected to the second sleeve, the second sleeve is hinged to the support ring, the second piston is hinged to the flexible layer, the inner cavity of the second sleeve is divided into chamber c and chamber d by the second piston, chamber d is connected to the lower chamber, and chamber d is located on the side of the second sleeve close to the support ring.

[0012] The first sleeve is used to provide a guide for the first piston. Hydraulic oil is filled in chamber a and the upper chamber. When the first piston expands outward along the first sleeve, the space in chamber a is compressed, allowing the hydraulic oil to flow into the upper chamber through the pipeline. Under the action of pressure, the upper support rod moves upward along the upper chamber to support the middle part of the flexible layer, and the support spring sleeved on the upper support rod is stretched; the second sleeve is used to provide a guide for the second piston. Hydraulic oil is also filled in chamber d and the lower chamber. When the second piston contracts inwardly along the second sleeve, the space in chamber d is compressed, allowing the hydraulic oil to flow into the lower chamber through the pipeline. Under the action of pressure, the lower support rod moves upward along the lower chamber, and the support spring sleeved on the lower support rod is compressed. The upper support rod and the lower support rod cooperate with the first adjusting member and the second adjusting member on both sides to form a three-point support for the flexible layer to maintain the stability of the deformed flexible layer.

[0013] Furthermore, two groups of electromagnets are provided in the first sleeve, one group of electromagnets is tightly connected to the inner wall of chamber b, and the other group of electromagnets is tightly connected to the first piston, and the facing ends of the two groups of electromagnets in the first sleeve are magnetic poles of the same name; Two groups of electromagnets are also provided in the second sleeve, one group of electromagnets is tightly connected to the inner wall of chamber d, and the other group of electromagnets is tightly connected to the second piston. The facing ends of the two groups of electromagnets in the second sleeve are opposite magnetic poles, and the electromagnets are electrically connected to the detection element.

[0014] When the detection element detects that the rust removal component moves to the arc section, the two groups of electromagnets in the first sleeve and the second sleeve are energized. The two groups of electromagnets in the first sleeve have like poles at the facing ends. According to the principle of like charges repel each other, under the action of magnetic force, the first piston is driven to move outward along the first sleeve; the two groups of electromagnets in the second sleeve have opposite poles at the facing ends. According to the principle of opposite charges attract each other, under the action of magnetic force, the second piston is driven to contract inward, so that the shape of the flexible layer changes to an arc, thereby matching the surface of the workpiece.

[0015] Furthermore, the detection element includes a connecting seat, a swing frame, a rotating roller, a varistor and a detection spring. The connecting seat is tightly connected to the flexible layer, an arc groove is provided on the connecting seat, the swing frame is rotatably connected to the connecting seat, the rotating roller is rotatably connected to the swing frame, the varistor is tightly connected to the connecting seat, one end of the detection spring is tightly connected to the swing frame, the other end of the detection spring is tightly connected to the varistor, and the varistor is electrically connected to the electromagnet.

[0016] When processing the straight section of the workpiece, the flexible layer is in the shape of a straight cylinder. When the flexible layer moves to the arc section, the arc surface of the workpiece will block the flexible layer, and the detection element at the front end of the flexible layer will be subjected to pressure, thereby exerting a certain thrust on the rotating roller. The greater the curvature of the arc section, the greater the thrust on the rotating roller. When the rotating roller is subjected to the thrust, it will drive the swing frame to deflect inward along its rotation center. The length of the swing frame in the arc groove is shorter than the length at the other end. According to the lever principle, the thrust on the rotating roller is amplified, so as to facilitate subsequent detection. When the swing frame swings along the arc groove, The detection spring is compressed by force, thereby transmitting pressure to the varistor. The greater the pressure on the varistor, the smaller the resistance. By detecting the resistance of the varistor, the curvature of the arc segment of the workpiece can be determined. The smaller the resistance of the varistor, the greater the curvature of the arc segment of the workpiece, and the current transmitted to the electromagnet increases accordingly, so that the outward expansion distance of the first adjustment member is longer, and the curvature of the arc segment into which the flexible layer changes is greater. The degree of change of the flexible layer is automatically adjusted according to the curvature of the arc segment of the workpiece, so that the shape of the flexible layer matches the workpiece, thereby improving the rust removal effect.

[0017] Furthermore, two groups of detection elements are provided, one group of detection elements is located near the first adjusting member, and the other group of detection elements is located near the second adjusting member.

[0018] A group of detection elements close to the second adjusting member is used to detect the curvature of the workpiece, and a group of detection elements close to the first adjusting member is used to detect whether the rust removal component has swept the arc segment. When the rust removal component has swept the arc segment, the rotating roller in this detection element is forced to deflect outward. At this time, the detection spring is stretched, and the varistor is stretched, and the resistance value increases. When it is detected that the resistance value of the varistor in a group of detection elements close to the first adjusting member becomes larger, the electromagnet is powered off. Under the elastic force of the supporting spring, the hydraulic oil flowing into the upper chamber and the lower chamber will return to chamber a and chamber d, and the deformed arc-shaped flexible layer will return to its original shape, thereby removing the rust on the straight line segment on the other side of the workpiece, realizing the automatic recovery of the adjusting component.

[0019] Furthermore, the clamping assembly includes an electric clamp and an electric push rod. A slide groove is provided on the workbench. The electric clamp is slidably connected to the slide groove. The electric push rod is firmly connected to the workbench. The output end of the electric push rod is transmission-connected to the electric clamp.

[0020] The workpiece to be processed is clamped vertically on the workbench. The electric clamp can clamp both ends of the workpiece, thereby providing a stable working environment for subsequent processing. The electric push rod is used to drive the electric clamp to slide along the slide groove on the workbench to adapt to workpieces of different sizes.

[0021] Furthermore, the movable component includes a column, a linear module, a slider, a rotating motor, a connecting rod and a movable push rod. The column is tightly connected to the workbench, the linear module is tightly connected to the column, the linear module is transmission-connected to the slider, the rotating motor is tightly connected to the slider, the output end of the rotating motor is transmission-connected to the connecting rod, the connecting rod is tightly connected to the movable push rod, and the output end of the movable push rod is transmission-connected to the adjustment component.

[0022] The column is used to provide an installation base for the linear module, and the linear module is used to drive the slider to slide up and down along the column. The rotating motor is used to drive the connecting rod to rotate, and then drive the movable push rod to rotate, thereby driving the adjustment component connected to the movable push rod to make an arc movement, so that the rust removal component makes an arc movement in the arc section of the workpiece to remove rust from it. The movable push rod is retractable to adapt to workpieces of different sizes.

[0023] Compared with the prior art, the present invention has the following beneficial effects: 1. The shape of the flexible layer 41 is changed by adjusting the component 5 so that the shape of the flexible layer 41 matches the shape of the arc segment, so that the grinding ring 42 fits the surface of the workpiece. The inverted trapezoidal grinding ring 42 can facilitate the change of the shape of the flexible layer 41, thereby performing rust removal on the arc segment of the workpiece without dead angles, thereby improving the rust removal effect.

[0024] 2. When the rust removal component 4 passes through the arc section of the workpiece, the first adjusting member 52 expands to both sides and the second adjusting member 53 contracts inward, so that the shape of the flexible layer 41 is changed to an arc shape, thereby fitting to the surface of the workpiece. When the first adjusting member 52 expands to both sides, it can drive the upper support rod 54 to move upward along the upper chamber 511. When the second adjusting member 53 contracts inward, it can drive the lower support rod 55 to move upward along the lower chamber 512, forming a three-point support for the flexible layer 41 to maintain the stability of the deformed flexible layer 41.

[0025] 3. When the flexible layer 41 moves to the arc segment, the arc surface of the workpiece will block the flexible layer 41, and the detection element 43 located at the front end of the flexible layer 41 will be subjected to pressure, thereby applying a certain thrust to the rotating roller 433, and the greater the curvature of the arc segment, the greater the thrust to the rotating roller 433, and the rotating roller 433 is subjected to the thrust, which will drive the swing frame 432 to deflect inward along its rotation center. The length of the swing frame 432 in the arc groove 4311 is smaller than the length at the other end. According to the lever principle, the thrust received by the rotating roller 433 is amplified, so as to facilitate subsequent detection. When the swing frame 432 swings along the arc groove 4311, the detection spring 435 is compressed by force, thereby transmitting pressure to the varistor 434, and the greater the pressure on the varistor 434, the smaller the resistance. By detecting the resistance of the varistor 434, the curvature of the arc segment of the workpiece can be determined. The smaller the resistance of the varistor 434, the greater the curvature of the arc segment of the workpiece, and the current transmitted to the electromagnet 57 increases accordingly, so that the first adjustment member 52 expands outward for a longer distance, and the curvature of the arc segment into which the flexible layer 41 changes becomes larger, thereby realizing automatic adjustment of the degree of change of the flexible layer 41 according to the curvature of the arc segment of the workpiece, so that the shape of the flexible layer 41 matches the workpiece, thereby improving the rust removal effect.

[0032] Example: Figure 1-Figure 8 As shown, the present invention provides a technical solution for a surface rust removal device for a marine pipeline support, the surface rust removal device comprises a workbench 1, a movable component 2, a clamping component 3, a rust removal component 4 and an adjusting component 5, the movable component 2 is tightly connected to the workbench 1, the clamping component 3 is tightly connected to the workbench 1, the rust removal component 4 is tightly connected to the movable component 2, the adjusting component 5 is tightly connected to the rust removal component 4, and the adjusting component 5 is used to adjust the state of the rust removal component 4.

[0033] The present invention is used for removing rust from a U-shaped pipeline support, and the U-shaped pipeline support is divided into an arc segment and a straight segment. The existing rust removal method is generally processed manually, which is difficult to fit the surface of the arc segment, and the rust removal effect cannot be guaranteed; the workbench 1 is used to provide stable support for each component. During the rust removal operation, the workpiece to be processed is first placed on the workbench 1, and then the clamping component 3 is started to fix the workpiece, and the rust removal component 4 is driven by the movable component 2 to sweep across the surface of the workpiece to remove rust from the workpiece. When the rust removal component 4 passes through the arc segment of the workpiece, the shape of the rust removal component 4 is adjusted by the adjusting component 5 to make it fit the surface of the workpiece, thereby ensuring the rust removal effect.

[0034] The rust removal component 4 includes a flexible layer 41, a grinding ring 42 and a detection element 43. The flexible layer 41 is tightly connected to the adjustment component 5. The grinding ring 42 is tightly connected to the flexible layer 41. The cross section of the grinding ring 42 is an inverted trapezoid. Several grinding rings 42 are arranged along the inner wall of the flexible layer 41. The detection element 43 is tightly connected to the flexible layer 41. The detection element 43 is used to detect the curvature of the workpiece.

[0035] The flexible layer 41 is in the shape of a circular tube, and the diameter of the flexible layer 41 matches the diameter of the workpiece. When removing rust, the workpiece is inserted into the flexible layer 41. When the rust removal component 4 sweeps across the surface of the workpiece driven by the movable component 2, when the rust removal component 4 passes through the straight section of the workpiece, the detection element 43 does not operate, and the grinding ring 42 on the inner wall of the flexible layer 41 abuts against the surface of the workpiece for processing. When the rust removal component 4 passes through the arc section of the workpiece, the detection element 43 operates and determines the curvature of the arc section, and then changes the shape of the flexible layer 41 through the adjustment component 5, so that the shape of the flexible layer 41 matches the shape of the arc section, so that the grinding ring 42 fits the surface of the workpiece, and the inverted trapezoidal grinding ring 42 can facilitate the change of the shape of the flexible layer 41, thereby performing rust removal on the arc section of the workpiece without dead angles, thereby improving the rust removal effect.

[0036] The adjusting component 5 includes a support ring 51, a first adjusting member 52, a second adjusting member 53, an upper support rod 54, a lower support rod 55 and a support spring 56. The support ring 51 is tightly connected to the movable component 2. One end of the first adjusting member 52 is hinged to the support ring 51, and the other end of the first adjusting member 52 is hinged to the flexible layer 41. One end of the second adjusting member 53 is hinged to the support ring 51, and the other end of the second adjusting member 53 is hinged to the flexible layer 41. An upper chamber 511 and a lower chamber 512 are provided in the support ring 51. The upper support rod 54 is slidably connected to the upper chamber 511, and the upper support rod 54 is tightly connected to the flexible layer 41. The lower support rod 55 is slidably connected to the lower chamber 512, and the lower support rod 55 is tightly connected to the flexible layer 41. The support spring 56 is sleeved on the upper support rod 54 and the lower support rod 55.

[0037] The support ring 51 is fixed on the movable component 2 to provide support for the rust removal component 4. The upper support rod 54 and the lower support rod 55 are respectively fixed on the upper and lower ends of the flexible layer 41 to provide support for it. The first adjusting member 52 is located above the support ring 51, and the second adjusting member 53 is located below the support ring 51. When the rust removal component 4 passes through the arc section of the workpiece, the first adjusting member 52 expands to both sides and the second adjusting member 53 contracts inward, so that the shape of the flexible layer 41 is changed to an arc shape, thereby fitting to the surface of the workpiece. When the first adjusting member 52 expands to both sides, it can drive the upper support rod 54 to move upward along the upper chamber 511. When the second adjusting member 53 contracts inward, it can drive the lower support rod 55 to move upward along the lower chamber 512, forming a three-point support for the flexible layer 41 to maintain the stability of the deformed flexible layer 41.

[0038] The first adjusting member 52 includes a first sleeve 521 and a first piston 522. The first piston 522 is slidably connected to the first sleeve 521. The first sleeve 521 is hinged to the support ring 51. The first piston 522 is hinged to the flexible layer 41. The inner cavity of the first sleeve 521 is divided into a chamber a5211 and a chamber b5212 by the first piston 522. The chamber a5211 is connected to the upper chamber 511. The chamber a5211 is located on a side of the first sleeve 521 away from the support ring 51. The second adjusting member 53 includes a second sleeve 531 and a second piston 532. The second piston 532 is slidably connected to the second sleeve 531. The second sleeve 531 is hinged to the support ring 51. The second piston 532 is hinged to the flexible layer 41. The inner cavity of the second sleeve 531 is divided into chamber c5311 and chamber d5312 by the second piston 532. Chamber d5312 is connected to the lower chamber 512. Chamber d5312 is located on the side of the second sleeve 531 close to the support ring 51.

[0039] The first sleeve 521 is used to provide a guide for the first piston 522. Hydraulic oil is filled in chamber a5211 and the upper chamber 511. When the first piston 522 expands outward along the first sleeve 521, the space in chamber a is compressed so that the hydraulic oil flows into the upper chamber 511 through the pipeline. Under the action of pressure, the upper support rod 54 moves upward along the upper chamber 511 to support the middle part of the flexible layer 41, and the support spring 56 sleeved on the upper support rod 54 is stretched; the second sleeve 531 is used to provide a guide for the second piston 532. The chamber d5 Hydraulic oil is also filled in the upper and lower chambers 312 and 512. When the second piston 532 contracts inwardly along the second sleeve 531, the space in the chamber d5312 is compressed, causing the hydraulic oil to flow into the lower chamber 512 through the pipeline. Under the action of pressure, the lower support rod 55 moves upward along the lower chamber 512, and the support spring 56 sleeved on the lower support rod 55 is compressed. The upper support rod 54 and the lower support rod 55 cooperate with the first adjusting member 52 and the second adjusting member 53 on both sides to form a three-point support for the flexible layer 41 to maintain the stability of the deformed flexible layer 41.

[0040] Two groups of electromagnets 57 are arranged in the first sleeve 521, one group of electromagnets 57 is tightly connected to the inner wall of the chamber b5212, and the other group of electromagnets 57 is tightly connected to the first piston 522, and the facing ends of the two groups of electromagnets 57 in the first sleeve 521 are the same magnetic poles; Two groups of electromagnets 57 are also provided in the second sleeve 531. One group of electromagnets 57 is firmly connected to the inner wall of the chamber d5312, and the other group of electromagnets 57 is firmly connected to the second piston 532. The facing ends of the two groups of electromagnets 57 in the second sleeve 531 are opposite magnetic poles, and the electromagnets 57 are electrically connected to the detection element 43.

[0041] When the detection element 43 detects that the rust removal component 4 moves to the arc section, the two groups of electromagnets 57 in the first sleeve 521 and the second sleeve 531 are energized. The two groups of electromagnets 57 in the first sleeve 521 have like poles at the facing ends. According to the principle of like charges repel each other, under the action of magnetic force, the first piston 522 is driven to move outward along the first sleeve 521; the two groups of electromagnets 57 in the second sleeve 531 have unlike poles at the facing ends. According to the principle of opposite charges attract each other, under the action of magnetic force, the second piston 532 is driven to contract inward, so that the shape of the flexible layer 41 changes to an arc, thereby matching the surface of the workpiece.

[0042] The detection element 43 includes a connecting seat 431, a swing frame 432, a rotating roller 433, a piezoresistor 434 and a detection spring 435. The connecting seat 431 is tightly connected to the flexible layer 41, an arc groove 4311 is provided on the connecting seat 431, the swing frame 432 is rotatably connected to the connecting seat 431, the rotating roller 433 is rotatably connected to the swing frame 432, the piezoresistor 434 is tightly connected to the connecting seat 431, one end of the detection spring 435 is tightly connected to the swing frame 432, the other end of the detection spring 435 is tightly connected to the piezoresistor 434, and the piezoresistor 434 is electrically connected to the electromagnet 57.

[0043] When processing the straight section of the workpiece, the flexible layer 41 is in the shape of a straight cylinder. When the flexible layer 41 moves to the arc section, the arc surface of the workpiece will block the flexible layer 41, and the detection element 43 located at the front end of the flexible layer 41 will be subjected to pressure, thereby applying a certain thrust to the rotating roller 433, and the greater the curvature of the arc section, the greater the thrust on the rotating roller 433, and the rotating roller 433 is subjected to the thrust, which will drive the swing frame 432 to deflect inward along its rotation center. The length of the swing frame 432 in the arc groove 4311 is smaller than the length at the other end. According to the lever principle, the thrust received by the rotating roller 433 is amplified, so as to facilitate subsequent detection. The swing frame 432 moves along the arc groove 4 When 311 swings, the detection spring 435 is compressed, thereby transmitting the pressure to the varistor 434. The greater the pressure on the varistor 434, the smaller the resistance. By detecting the resistance of the varistor 434, the curvature of the arc segment of the workpiece can be determined. The smaller the resistance of the varistor 434, the greater the curvature of the arc segment of the workpiece, and the current transmitted to the electromagnet 57 increases accordingly, so that the first adjustment member 52 expands outward for a longer distance, and the curvature of the arc segment into which the flexible layer 41 changes becomes larger. The degree of change of the flexible layer 41 is automatically adjusted according to the curvature of the arc segment of the workpiece, so that the shape of the flexible layer 41 matches the workpiece, thereby improving the rust removal effect.

[0044] There are two groups of detection elements 43 , one group of detection elements 43 is located near the first adjustment member 52 , and the other group of detection elements 43 is located near the second adjustment member 5 .

[0045] A group of detection elements 43 near the second adjusting member 53 is used to detect the curvature of the workpiece, and a group of detection elements 43 near the first adjusting member 52 is used to detect whether the rust removal component 4 has swept the arc segment. When the rust removal component 4 has swept the arc segment, the rotating roller 433 in this detection element 43 is forced to deflect outward. At this time, the detection spring 435 is stretched and the piezoresistor 434 is stretched and the resistance value increases. When it is detected that the resistance value of the piezoresistor 434 in a group of detection elements 43 near the first adjusting member 52 becomes larger, the electromagnet 57 is powered off. Under the elastic force of the supporting spring 56, the hydraulic oil flowing into the upper chamber 511 and the lower chamber 512 will return to the chamber a5211 and the chamber d5312, and the deformed arc-shaped flexible layer 41 will return to its original shape, thereby removing the rust from the straight line segment on the other side of the workpiece, thereby realizing the automatic recovery of the adjustment component 5.

[0046] The clamping assembly 3 includes an electric clamp 31 and an electric push rod 32. A slide groove 11 is provided on the workbench 1. The electric clamp 31 is slidably connected to the slide groove 11. The electric push rod 32 is firmly connected to the workbench 1. The output end of the electric push rod 32 is transmission-connected to the electric clamp 31.

[0047] The workpiece to be processed is clamped vertically on the workbench 1. The electric clamp 31 can clamp both ends of the workpiece, thereby providing a stable working environment for subsequent processing. The electric push rod 32 is used to drive the electric clamp 31 to slide along the slide groove 11 on the workbench 1 to adapt to workpieces of different sizes.

[0048] The movable component 2 includes a column 21, a linear module 22, a slider 23, a rotating motor 24, a connecting rod 25 and a movable push rod 26. The column 21 is tightly connected to the workbench 1, the linear module 22 is tightly connected to the column 21, the linear module 22 is transmission-connected to the slider 23, the rotating motor 24 is tightly connected to the slider 23, the output end of the rotating motor 24 is transmission-connected to the connecting rod 25, the connecting rod 25 is tightly connected to the movable push rod 26, and the output end of the movable push rod 26 is transmission-connected to the adjustment component 5.

[0049] The column 21 is used to provide an installation base for the linear module 22. The linear module 22 is used to drive the slider 23 to slide up and down along the column 21. The rotating motor 24 is used to drive the connecting rod 25 to rotate, and then drive the movable push rod 26 to rotate, thereby driving the adjustment component 5 connected to the movable push rod 26 to make an arc movement, so that the rust removal component 4 makes an arc movement in the arc section of the workpiece to remove rust from it. The movable push rod 26 is retractable to adapt to workpieces of different sizes.

[0050] The working principle of the present invention is as follows: when the rust removal component 4 passes through the arc section of the workpiece, the arc surface of the workpiece will block the flexible layer 41, and the detection element 43 located at the front end of the flexible layer 41 will be subjected to pressure, thereby applying a certain thrust to the rotating roller 433, and the greater the curvature of the arc section, the greater the thrust to the rotating roller 433, and the rotating roller 433 is subjected to the thrust, which will drive the swing frame 432 to deflect inward along its rotation center, and when the swing frame 432 swings along the arc groove 4311, the detection spring 435 is compressed by force, thereby transmitting the pressure to the varistor 434, and the pressure The greater the pressure on the varistor 434, the smaller the resistance. By detecting the resistance of the varistor 434, the curvature of the arc segment of the workpiece can be determined. The smaller the resistance of the varistor 434, the greater the curvature of the arc segment of the workpiece, and the current transmitted to the electromagnet 57 increases accordingly, so that the first adjustment member 52 expands outwardly for a longer distance, and the curvature of the arc segment into which the flexible layer 41 changes becomes greater. The degree of change of the flexible layer 41 is automatically adjusted according to the curvature of the arc segment of the workpiece, so that the shape of the flexible layer 41 matches the workpiece, thereby improving the rust removal effect.
