Description

Technical Field

[0001] This invention relates to the technical field of open arc welding, and in particular to a quick-change mechanism for open arc welding equipment. Background Technology

[0002] Wear-resistant steel plate surfacing is a process that uses welding technology to clad a layer of alloy with high hardness and high wear resistance onto the surface of ordinary carbon steel or low alloy steel substrate.

[0003] The three most commonly used welding processes in industry are: Manual arc welding: Features: Simple equipment, flexible operation, it's practically a "universal solution".

[0004] Applicable scenarios: single-piece or small-batch production, or on-site repair of complex-shaped parts.

[0005] Solid welding wire open arc welding: Features: No flux covering required, visible arc, high deposition efficiency, and easy to automate.

[0006] Applicable scenarios: continuous welding on large areas and flat surfaces, often used in the manufacture of standard wear-resistant composite steel plates.

[0007] Submerged arc welding with flux-cored wire: Features: The electric arc burns under the flux layer, resulting in extremely stable welding quality, no arc spatter, and controllable penetration depth.

[0008] Applicable scenarios: large-scale production of medium-thick-walled workpieces with extremely high requirements for surface quality and dimensional accuracy.

[0009] In existing wear-resistant plate surfacing equipment, the replacement, disassembly, and installation of welding wire, steel plate, and conductive nozzle are cumbersome and time-consuming. Furthermore, the equipment requires re-adjustment and repositioning after replacement, which affects production efficiency. At the same time, the steel plate is prone to positioning deviation during the replacement process, resulting in poor weld formation and increased defect rate. This equipment cannot meet the intelligent production requirements of "production upon component replacement" and restricts the improvement of equipment production efficiency.

[0039] This invention uses two movable baffle assemblies on the side plate surface to adjust the overall width between the three baffle assemblies to accommodate steel plates of different widths. At the same time, the meshing of the toothed plate and the adjusting gear is adjusted to ensure that the baffle assemblies at both ends move synchronously in opposite directions, so that the side of the steel plate is subjected to uniform force after adjustment.

[0040] This invention utilizes a tension rope, pressure rods, pressure blocks, and pressure detection controllers in combination. The contact blocks are gradually pushed into the inner side of their corresponding main blocks, causing the corresponding pressure rods to move. All the corresponding pressure rods apply tension to the tension rope, causing it to bend and pull the pressure blocks to apply pressure to the pressure detection controllers. After all the contact blocks corresponding to the side strips on both sides have entered the inner side of their respective main blocks, the two corresponding pressure blocks apply pressure to the two pressure detection controllers respectively. Once both pressure detection controllers are under pressure, they control the telescopic cylinder to move the through-plate upwards, causing the magnet block to adhere and fix to the bottom surface of the upright steel plate.

[0047] The following is in conjunction with the appendix Figures 1-10 The present invention will be described in further detail below.

[0048] This invention discloses a quick-change mechanism for open-arc welding equipment. For example... Figures 1-10 As shown, it includes a welding workbench 1, a three-dimensional space control module 2, a welding mounting frame 3, a sliding support assembly 6, a magnetic positioning assembly 7, and a horizontal baffle unit 8.

[0049] The three-dimensional space control module 2 is installed on the upper side of the welding workbench 1. The welding mounting frame 3 is connected to the three-dimensional space control module 2. The three-dimensional space control module 2 controls the vertical and horizontal spatial movement of the welding mounting frame 3.

[0050] In this embodiment, the three-dimensional space control module 2 includes a cross frame, longitudinal frames, and a movable frame. The movable frame slides outside the cross frame, and the two ends of the cross frame move inside the two longitudinal frames respectively. A threaded rod driven by a motor is installed inside the longitudinal frame. The rotation of the threaded rod drives the cross frame to slide inside the longitudinal frame. A drive wheel driven by a motor is installed inside the movable frame. The drive wheel contacts the cross frame and drives the movable frame to move horizontally relative to the cross frame. A power telescopic cylinder capable of power extension is installed on the longitudinal frame. The power telescopic cylinder is connected to the welding workbench 1. The welding mounting frame 3 is installed on the bottom surface of the movable frame and can drive the welding mounting frame 3 to move up and down and in the horizontal and vertical directions for welding the steel plate plane on the lower side.

[0051] The welding mounting frame 3 is equipped with an axial quick-release assembly 4. A welding wire wheel capable of quick release is installed on the outside of the axial quick-release assembly 4. A conductive head 10 is provided on the lower side of the welding mounting frame 3 below the axial quick-release assembly 4. The welding mounting frame 3 is quickly connected to the conductive head 10 through a conductive quick-release assembly 5.

[0052] Furthermore, in an alternative embodiment, the axial quick-release assembly 4 includes a mounting shaft 41 and a quick-release pressure cylinder 43.

[0053] One end of the mounting shaft 41 is rotatably connected to the welding mounting bracket 3, and the other end of the mounting shaft 41 is coaxially mounted with a minor diameter shaft 42. A quick-release pressure cylinder 43 is slidably sleeved on the outer surface of the minor diameter shaft 42. The outer diameter of the quick-release pressure cylinder 43 is smaller than the outer diameter of the mounting shaft 41. A triangular stop 44 is slidably inserted between the quick-release pressure cylinder 43 and the mounting shaft 41 on the circumferential surface of the minor diameter shaft 42. The triangular stop 44 is elastically connected to the minor diameter shaft 42. The side of the triangular stop 44 away from the mounting shaft 41 is an inclined surface, and the side of the triangular stop 44 close to the mounting shaft 41 is set perpendicular to the axis of the mounting shaft 41. The farthest distance between the triangular stop 44 and the axis of the minor diameter shaft 42 is greater than the outer circumference of the mounting shaft 41.

[0054] When using the welding wire wheel, place the welding wire wheel on the outside of the quick-release pressure cylinder 43, and then manually push the welding wire wheel to apply a thrust to the mounting shaft 41. After the welding wire wheel contacts the inclined surface of the triangular stop 44, push the triangular stop 44 to gradually retract inward, so that the welding wire wheel moves to the other side of the triangular stop 44. The side of the triangular stop 44 perpendicular to the axis of the mounting shaft 41 blocks the welding wire wheel, thus completing the installation of the welding wire wheel. When disassembling, push the quick-release pressure cylinder 43 close to the mounting shaft 41 and push the triangular stop 44 into the small diameter shaft 42 so that the welding wire wheel can be removed and replaced with a new welding wire wheel.

[0055] In this embodiment, the welding mounting frame 3 is equipped with a wheel axle that drives the welding wire to move between the conductive head 10 and the welding wire wheel. The welding mounting frame 3 is equipped with a motor that drives the wheel axle to rotate. The welding wire passes through the two wheel axles and then through the conductive head 10. When the wheel axle rotates, it pushes the welding wire to move.

[0056] The upper end of the conductive head 10 is provided with a coaxial annular groove.

[0057] The conductive quick-release assembly 5 includes a conductive support plate 51 and a snap-fit ​​block 53.

[0058] The conductive support plate 51 is connected to the welding mounting frame 3. The conductive support plate 51 has a snap-fit ​​groove 52 at the end away from the welding mounting frame 3. The height and width of the snap-fit ​​groove 52 are adapted to the outer ring diameter and height of the annular groove, respectively. The conductive head 10 is located inside the snap-fit ​​groove 52.

[0059] There are two latching blocks 53. The two latching blocks 53 are slidably inserted into the inner walls of the latching groove 52 on both sides at one end away from each other. The two latching blocks 53 are connected to the conductive support plate 51 at the one end away from each other. The two latching blocks 53 are arranged in a figure-eight shape on the outer part of the latching groove 52.

[0060] During installation, the conductive head 10 is pushed to apply a pushing force to the two sides of the two latching blocks 53 that form an eight-shaped shape, pushing the two latching blocks 53 away from each other. The conductive head 10 enters the latching groove 52 and the rear side of the latching block 53. The latching block 53 prevents the conductive head 10 from disengaging from the latching groove 52. At the same time, the conductive support plate 51 contacts the upper and lower inner walls of the annular groove respectively, thus supporting the conductive head 10.

[0061] The sliding support assembly 6 is connected to the welding workbench 1. The welding mounting frame 3 is located on the upper side of the sliding support assembly 6. The magnetic positioning assembly 7 is installed on the upper side of the welding workbench 1. The magnetic positioning assembly 7 can move up and down relative to the welding workbench 1. The magnetic positioning assembly 7 can move up and down relative to the sliding support assembly 6.

[0062] There are two horizontal baffle units 8. The conductive head 10 is located between the two horizontal baffle units 8. The horizontal baffle units 8 are located on the upper side of the sliding support assembly 6. The welding workbench 1 is equipped with opposing drive units 9 that drive the two horizontal baffle units 8 to move in opposite directions.

[0063] In this embodiment, the welding workbench 1 consists of a base and a gantry frame. The gantry frame is installed on the upper side of the base. The three-dimensional space control module 2 and the opposing drive unit 9 are installed on the gantry frame. The sliding support assembly 6 and the magnetic positioning assembly 7 are installed on the upper side of the base of the welding workbench 1.

[0064] The steel plate to be processed is placed on the upper side of the sliding support assembly 6, and the two horizontal baffle units 8 are brought close to each other. By applying a pushing force to both sides of the steel plate, the steel plate is gradually straightened. Then, the magnetic positioning assembly 7 is driven to move upward and magnetically attract the bottom surface of the steel plate. Then, the horizontal baffle unit 8 is controlled to disengage from the steel plate so as not to interfere with the movement of the welding part during the welding of the steel plate.

[0065] Furthermore, in an alternative embodiment, the sliding support assembly 6 includes a main body plate 61 and a main body support rod 62.

[0066] The main plate 61 is installed on the upper surface of the welding workbench 1. Multiple main support rods 62 are provided. The multiple main support rods 62 are installed in a square matrix at equal intervals on the upper surface of the main plate 61. The upper end of the main support rod 62 is rotatably embedded with ball bearings 63. The upper surface of the ball bearings 63 is tangent to the bottom surface of the horizontal baffle unit 8.

[0067] When in use, the steel plate to be processed is placed on the upper side of the ball bearing 63. When the horizontal baffle unit 8 applies a pushing force to the steel plate, the steel plate drives the contacting ball bearing 63 to rotate, reducing the wear on the bottom surface when the steel plate moves, and at the same time reducing the resistance encountered when pushing the steel plate.

[0068] The magnetic positioning assembly 7 includes a linkage plate 71, and a drive telescopic cylinder 73 is installed on the bottom surface of the linkage plate 71. The lower end of the drive telescopic cylinder 73 is installed on the upper surface of the welding workbench 1.

[0069] The upper end of the main support rod 62 is truncated cone-shaped. A magnet block 72 is slidably sleeved on the truncated cone-shaped part of the main support rod 62. The magnet block 72 can move upward relative to the main support rod 62. The bottom surface of the magnet block 72 is located on both sides of the main support rod 62 to which it is connected. A through plate 74 is installed. The lower end of the through plate 74 slides through the upper surface of the main plate 61. The end of the through plate 74 located on the lower side of the main plate 61 is connected to the linkage plate 71. The upper surface of the magnet block 72 is located below the upper surface of the ball bearing 63.

[0070] When in use, once the steel plate no longer tilts under the push of the horizontal baffle units 8 on both sides, the drive telescopic cylinder 73 controls the linkage plate 71 to move the through plate 74 and the connected magnet block 72 upward to attract the bottom of the steel plate, and then controls the horizontal baffle unit 8 to detach from the steel plate.

[0071] In this embodiment, the magnet block 72 is made of an electromagnet or a strong magnet.

[0072] Furthermore, in an optional embodiment, the opposing drive unit 9 includes a suspension fixing block 91, a clamping drive gear 92, and a clamping frame 93.

[0073] The suspension fixing block 91 is installed at the middle position of the upper end of the welding workbench 1, and the clamping drive gear 92 is installed on the lower side of the suspension fixing block 91. The clamping drive gear 92 rotates relative to the suspension fixing block 91.

[0074] There are two clamping frames 93. The two clamping frames 93 are connected to two horizontal baffle units 8 respectively. The two clamping frames 93 are slidably inserted into both sides of the suspension fixing block 91. The clamping drive gear 92 has clamping tooth plates 94 meshing on both sides. The two clamping tooth plates 94 are fixed to the two clamping frames 93 respectively.

[0075] In this embodiment, the suspension fixing block 91 is equipped with a motor that drives the clamping drive gear 92 to rotate in both directions. When the clamping drive gear 92 rotates in both directions, it meshes with the two clamping tooth plates 94, thereby driving the two clamping frames 93 to move closer to each other or further away from each other.

[0076] The horizontal baffle unit 8 includes a side strip 81 and a baffle assembly 82.

[0077] The middle part of the upper surface of the side strip plate 81 is fixedly installed with the adjacent clamping frame 93. There are three baffle assemblies 82. The middle baffle assembly 82 is connected to the middle position of the side strip plate 81, and the other two baffle assemblies 82 are slidably connected to the side strip plate 81.

[0078] An adjusting gear 83 is rotatably mounted at the middle position of the upper surface of the side strip 81. Two adjusting gear plates 84 mesh on both sides of the adjusting gear 83. Two baffle assemblies 82 that are slidably connected to the side strip 81 are respectively connected to the two adjusting gear plates 84.

[0079] Adjusting gear 83 is rotatably connected to clamping frame 93. One end of adjusting gear 83 on the upper side of clamping frame 93 is equipped with bevel gear meshing assembly 85. Bevel gear meshing assembly 85 is composed of two meshing bevel gears. The other bevel gear of bevel gear meshing assembly 85 is coaxially slidably inserted with prism shaft 86. Bevel gear meshing assembly 85 is connected to clamping frame 93. Both bevel gears of bevel gear meshing assembly 85 can rotate relative to clamping frame 93. Suspension fixing block 91 is equipped with double-head motor 87. Prism shaft 86 is coaxially connected to an adjacent output end of double-head motor 87.

[0080] When the two clamping frames 93 move relative to the suspension fixing block 91, the bevel gear on the upper side of the bevel gear meshing assembly 85 slides on the outside of the prism shaft 86. When the prism shaft 86 rotates, it drives the adjusting gear 83 to rotate through transmission. The adjusting gear 83 meshes with the adjusting tooth plate 84, which drives the two sliding baffle assemblies 82 on the outside of the side strip plate 81 to move, controlling the width range of the three baffle assemblies 82 installed on the surface of the side strip plate 81 to push the steel plate. At the same time, the baffle assemblies 82 at both ends are equidistant from the baffle assembly 82 in the middle and are symmetrically distributed.

[0081] The baffle assembly 82 includes a main block 821 and a contact block 822. The main block 821 is located between the side strip 81 and the contact block 822. The main block 821 is connected to the side strip 81. The contact block 822 is slidably inserted into the end of the main block 821 away from the side strip 81. The contact block 822 is elastically connected to the main block 821.

[0082] In this embodiment, the contact block 822 and the main block 821 are elastically connected by an elastic telescopic rod, which pushes the contact block 822 to move outward from the main block 821.

[0083] The adjusting tooth plate 84 is connected to the corresponding adjacent main block 821.

[0084] The side strip 81 has a groove on the side near the contact block 822. Multiple rotatable steering wheels 823 are installed inside the groove of the side strip 81. An end rod 824 is fixedly inserted into the middle position on the side of the side strip 81 away from the contact block 822. A pressure block 825 is slidably inserted into the end rod 824. A pressure detection controller 827 is provided on the side of the pressure block 825 near the side strip 81.

[0085] A tensioning rope 826 is provided on the inner side of the side strip 81. One end of the tensioning rope 826 is fixed to the side strip 81, and the other end of the tensioning rope 826 passes around multiple steering wheels 823 and extends into the end rod 824. One end of the tensioning rope 826 located inside the end rod 824 is connected to the pressure block 825. The pressure detection controller 827 is slidably sleeved on the outer surface of the adjacent tensioning rope 826. One end of the contact block 822 located inside the main block 821 is fixed with a pressure rod 828. The pressure rod 828 slides through the adjacent main block 821 and extends into the adjacent side strip 81.

[0086] In this embodiment, multiple steering wheels 823 limit the tension rope 826 to be connected to and moved by the pressure block 825 and disposed of by the pressure block 825. The tension rope 826 enters the side strip plate 81 from the end rod 824 and bends vertically. At the same time, the tension rope 826 bends away from the end fixed to the side strip plate 81. Then, under the steering limitation of the corresponding steering wheel 823, it is bent at two right angles to ensure that the part of the tension rope 826 near the pressure rod 828 is perpendicular to the pressure rod 828.

[0087] After the contact block 822 contacts the steel plate and the steel plate stops moving, as the two side plates 81 continue to approach, they push the contact block 822 into the inner side of the corresponding main block 821, causing the corresponding pressure rod 828 to move. After all the contact blocks 822 corresponding to the side plates 81 have entered the inner side of the main block 821, all the corresponding pressure rods 828 apply a pushing force to the tension rope 826, causing the tension rope 826 to bend and pull the pressure block 825 to apply pressure to the pressure detection controller 827.

[0088] Only when all the contact blocks 822 corresponding to the side strip 81 are inside the main block 821, the corresponding pressure rod 828 applies a pushing force to bend the tension rope 826, which can drive the pressure block 825 to apply pressure to the pressure detection controller 827. When only one pressure detection controller 827 is under pressure, it will not control the drive telescopic cylinder 73 to drive the through plate 74 to move upward.

[0089] Once the steel plate is no longer tilted, the contact blocks 822 corresponding to the side strips 81 on both sides all enter the inner side of the corresponding main block 821. Then, the two pressure blocks 825 apply pressure to the two pressure detection controllers 827 respectively. After both pressure detection controllers 827 are under pressure, they control the drive telescopic cylinder 73 to move the through plate 74 upward, so that the magnet block 72 is attracted and fixed to the bottom surface of the steel plate. Then, the two side strips 81 are controlled to move away from each other, ensuring that the magnet block 72 will only move upward to magnetically attract and fix the steel plate after the steel plate is straightened.

[0090] The working principle is as follows: The steel plate to be processed is placed on the upper side of the sliding support assembly 6. The welding wire wheel is quickly replaced by the axial quick-release assembly 4, and the conductive head 10 is quickly replaced by the conductive quick-release assembly 5. The opposing drive unit 9 controls the two horizontal baffle units 8 to move closer to each other, gradually pushing the steel plate between them to straighten it so that the steel plate is no longer tilted, which facilitates precise welding of the steel plate. After the steel plate is no longer tilted, the magnetic positioning assembly 7 is controlled to move upward to magnetically fix the bottom of the steel plate. Then, the horizontal baffle unit 8 is controlled to disengage from the steel plate to prevent the welding unit from interfering with the movement of the steel plate during welding. The three-dimensional space control module 2 drives the welding mounting frame 3 and the conductive head 10 to move. First, the welding wire in the conductive head 10 is controlled to contact the steel plate, and then the conductive head 10 and the inner welding wire are controlled to move horizontally to uniformly weld the steel plate.

[0091] The above are all preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, all equivalent changes made in accordance with the structure, shape and principle of the present invention should be covered within the scope of protection of the present invention.
