Description

Technical Field

[0001] The present invention relates to the technical field of welding workbenches, and more particularly to a welding limit workbench and method for assembling and welding special-shaped parts of a powder tank truck. Background Art

[0002] Welding is a process method for permanently connecting metal materials. Welding technology is applied in the manufacturing of industrial products in various industries such as boilers, pressure vessels, power generation equipment, pipelines, automobiles, shipbuilding, construction machinery, machine manufacturing, medical devices, precision instruments, and electronics. Welding technology plays a very important role in modern industrial production. A welding workbench refers to a workbench set up for welding small workpieces. The surface of the welding workbench generally has T-shaped grooves or holes for convenient use. The material of the welding platform is generally HT200 or HT250, and these two materials account for more than 98% of the welding platform material. It can not only meet the requirements during welding of workpieces but also has a relatively low price. Both the tensile strength, hardness, and wear resistance of the welding platform can meet the welding requirements.

[0003] In recent years, welding technology has developed rapidly, and fully automatic welding machines have been manufactured, eliminating the need for manual welding of workpieces. However, the cost of fully automatic welding machines is high, and the technical level requirements for operators are also very high. Most enterprises still choose to use manual welding, but manual welding has low efficiency, poor positioning of workpieces, and cannot always keep the welding position on a reference line, resulting in poor welding accuracy. The welding processing quality is difficult to guarantee. At the same time, it is necessary to manually flip and move the workpiece to a suitable position, resulting in high welding intensity. Summary of the Invention

[0004] Based on this, in view of the problems in the prior art, it is necessary to provide a welding limit workbench and method for assembling and welding special-shaped parts of a powder tank truck.

[0022] A locking accommodating groove for the second locking post to move is formed at the bottom of the workbench. A locking limit groove for cooperating with the locking limit block to limit the movement of the second locking post is formed at the top of the locking accommodating groove.

[0023] Further, a first limiting groove for limiting is formed at the bottom of the workbench. The telescopic mechanism includes a fixed sliding groove fixedly arranged at the bottom end of the workbench and perpendicular to the length side of the workbench. One end of the fixed sliding groove is in contact with the accommodating box so that the first locking post extends into the inside of the fixed sliding groove. The fixed sliding groove includes:

[0024] Two groups of first springs are fixedly arranged in the middle of the inner side of the fixed sliding groove. Each group of first springs is arranged along the length side direction of the fixed sliding groove and extends outward;

[0025] Two telescopic plates. Each telescopic plate is sleeved on one end of a group of first springs extending outward.

[0031] Furthermore, the correction limiting component includes an upper limiting plate and a lower limiting plate that cooperates with the upper limiting plate to limit the correction of the long iron sheet. An avoidance groove for the pressing plate to pass through is formed in the middle of the upper limiting plate.

[0032] A using method of a special-shaped part welding limiting workbench for a powder tank truck includes the following steps:

[0033] S1: The staff starts the lifting component, so that the upper lifting block, the lower lifting block and the special-shaped part correction table are lifted.

[0034] S2: After the equipment is lifted, the staff places the cylindrical barrel, the upper triangular piece and the lower triangular piece on the equipment. The staff inserts the long iron sheet into the clamping groove, and then starts the lifting component again, so that the lower lifting block presses on the lower triangular piece and the pressing plate presses on the upper triangular piece to complete the fixing work of the welding parts.

[0035] S3: Start the first lead screw slide table. When the cylindrical barrel at the forefront contacts the long iron sheet, the first locking column retracts inward, disengages from the locking hole, and the telescopic plate moves outward under the action of the first spring, drives the clamping plate to move outward through the connecting block, and releases the clamping of the long iron sheet.

[0036] S4: The moving platform abuts against the long iron sheet and continues to move into the correction welding box. The rollers on the correction components cooperate with the cylindrical barrel to correct and fold the long iron sheet so that it finally fits on both sides of the upper triangular piece and the lower triangular piece. During the correction process, the upper limiting plate and the lower limiting plate cooperate to limit the long iron sheet being corrected to ensure the accuracy of the correction.

[0037] S5: After the correction is completed, the staff welds the long iron sheet to the cylindrical barrel, the upper triangular piece and the lower triangular piece through the upper welding groove and the lower welding groove. After the welding is completed, start the equipment. After moving to the initial position, start the lifting component to take the special-shaped part off the special-shaped part correction table to complete the entire welding operation.

[0038] The beneficial effects of the present invention compared with the prior art are as follows:

[0039] First, through components such as the support platform, pressure plate, and special-shaped part correction table, all welding parts can be processed and loaded at one time. Compared with the traditional method of processing and welding two parts pairwise, it not only improves work efficiency but also reduces the work intensity of the staff.

[0040] Second, through mechanisms such as the unlocking mechanism and telescopic mechanism, accurate positioning and automatic unlocking of long iron sheets of different sizes are achieved, improving the welding accuracy.

[0041] Third, through the correction welding box, not only the accurate fitting of the long iron sheet is achieved, but also the welding work of the entire special-shaped component can be completed at one time. This not only reduces the difficulty of part positioning but also greatly improves work efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners

[0053] In order to further understand the features, technical means, specific purposes and functions achieved by the present invention, the present invention will be further described in detail below with reference to the drawings and specific implementation manners.

[0054] Refer to Figures 1 to 10 A special-shaped part welding limit workbench for a powder tank truck shown in the figure, comprising:

[0055] The workbench 1 is set in a horizontal state, and a lower welding groove 6 serving as a welding channel is formed at the bottom of the workbench 1; the correction welding box 26 is fixedly set on the workbench 1 in a horizontal state. The correction welding box 26 includes a correction mechanism 27 for extruding and correcting welding materials, a correction limit component 34 for limiting the correction process of welding materials, and an upper welding groove 38 serving as a welding channel; the translation mechanism 7 is fixedly set on the workbench 1 in a horizontal state. The translation mechanism 7 includes a moving platform 9 for fixing welding materials. The moving platform 9 includes a cylindrical barrel 13, a lower triangular piece 14, and a lifting component 15. The cylindrical barrel 13 is vertically sleeved at one end of the moving platform 9 close to the correction welding box 26. The lower triangular piece 14 is set horizontally in the middle of the moving platform 9. The lifting component 15 is fixedly set vertically at one end of the moving platform 9 away from the correction welding box 26. An irregular part correction table 24 is fixedly set at the lifting output end of the lifting component 15, and an upper triangular piece 25 is arranged at the top of the irregular part correction table 24; the unlocking mechanism 39 is set horizontally at the bottom of the workbench 1, and the triggering end of the unlocking mechanism 39 extends from the bottom end of the workbench 1 to the top end of the workbench 1; the telescopic mechanism 49 is set horizontally on both sides of the workbench 1. The telescopic end of the telescopic mechanism 49 is unlocked through the unlocking end of the unlocking mechanism 39. A vertically arranged long iron sheet 60 is slidably set at the top of the telescopic mechanism 49, and at the same time, the long iron sheet 60 is arranged in the middle of the correction limit component 34.

[0056] Place welding parts such as the cylindrical barrel 13, the upper triangular piece 25, and the lower triangular piece 14 on the moving platform 9, fix these parts by using the lifting component 15, place the long iron sheet 60 on the telescopic mechanism 49, start the translation mechanism 7. When the cylindrical barrel 13 touches the long iron sheet 60, the moving platform 9 triggers the unlocking mechanism 39 to unlock the telescopic mechanism 49 and release the clamping of the long iron sheet 60. The translation mechanism 7 continues to move into the correction welding box 26. The correction mechanism 27 and the irregular part correction table 24 cooperate to fold and correct the long iron sheet 60. The correction limit component 34 limits and fixes the correction process to prevent dislocation. After completing the folding correction, the staff welds the long iron sheet 60 to the cylindrical barrel 13, the upper triangular piece 25, and the lower triangular piece 14 through the upper welding groove 38 and the lower welding groove 6. After completing the welding, start the translation mechanism 7, and the moving platform 9 returns to the initial position. Start the lifting component 15 to remove the welded irregular parts from the irregular part correction table 24 to complete the entire welding operation.

[0057] To solve the problem of how to place welding parts such as the cylindrical barrel 13 and the lower triangular piece 14, the following features are specifically set:

[0058] The translation mechanism 7 includes a first lead screw slide table 8 fixedly arranged at the top end of the workbench 1. The first lead screw slide table 8 includes a moving base 10 at the output end. The bottom of the moving platform 9 is fixedly arranged on the moving base 10. The moving platform 9 includes a support platform 11 for placing the lower triangular piece 14. One end of the support platform 11 is formed with a fixed column 12 for sleeving the cylindrical barrel 13.

[0059] The moving base 10 drives the entire moving platform 9 to move through the first lead screw slide table 8. The lower triangular piece 14 is placed on the support platform 11 and fixed by the gravity of the special-shaped part correction table 24. The cylindrical barrel 13 is fixed by sleeving on the fixed column 12.

[0060] To solve the problems of how the special-shaped part correction table 24 is lifted and how the upper triangular piece 25 is fixed, the following features are specifically set:

[0061] The lifting component 15 includes: a second lead screw slide table 16 fixedly arranged at the top end of the moving platform 9. The second lead screw slide table 16 includes a threaded sleeve 19 at the output end. A convex ring 20 is formed at the bottom end of the threaded sleeve 19; an upper lifting block 17 is fixedly arranged at the top end of the threaded sleeve 19 and is slidably connected with the second lead screw slide table 16. One end of the upper lifting block 17 close to the correction welding box 26 is fixedly provided with a pressing plate 18 for pressing the upper triangular piece 25; a lower lifting block 21 is slidably connected with the second lead screw slide table 16. A lifting limit groove 22 for the convex ring 20 to move is formed at the bottom end of the lower lifting block 21. A lifting groove 23 for the threaded sleeve 19 to move is formed at the top end of the lifting limit groove 22. The lower lifting block 21 is the lifting output end of the above-mentioned lifting component 15.

[0062] When the lifting component 15 rises, the second lead screw slide table 16 is started. The threaded sleeve 19 drives the pressing plate 18 to rise through the upper lifting block 17 in the lifting groove 23. When the threaded sleeve 19 rises to a certain height, the convex ring 20 contacts the top of the lifting limit groove 22, driving the lower lifting block 21 to continue rising, and the special-shaped part correction table 24 also rises together with the lower lifting block 21.

[0063] When the lifting component 15 descends, the second lead screw slide table 16 is started. The threaded sleeve 19 starts to drive the upper lifting block 17 to move downward. The lower lifting block 21 moves downward following the threaded sleeve 19 under the action of gravity. When the lower lifting block 21 descends to the lowest point, it just presses on the lower triangular piece 14 to complete the fixing of the part. The threaded sleeve 19 drives the upper lifting block 17 to continue descending until the pressing plate 18 presses on the upper triangular piece 25 and then stops descending to complete the fixing work of the welded part.

[0064] To solve the problem of how the unlocking mechanism 39 unlocks the telescopic end of the telescopic mechanism 49, the following features are specifically set:

[0065] The unlocking mechanism 39 includes two receiving boxes 40 fixed to both sides of the bottom of the workbench 1. The receiving box 40 includes: a second spring 41, horizontally and fixedly arranged on the side wall of the bottom end of the receiving box 40 away from the correction welding box 26; a first locking post 42, slidably arranged at the bottom end of the receiving box 40. The bottom end of the first locking post 42 is sleeved on one end of the second spring 41 close to the correction welding box 26. An upper beveled portion 43 is formed at the top end of the first locking post 42. The first locking post 42 is the unlocking end of the unlocking mechanism 39; a plurality of third springs 44, all vertically and fixedly arranged at one end of the middle part of the receiving box 40 close to the correction welding box 26; a second locking post 45, vertically sleeved on the top end of the third spring 44. A lower beveled portion 48 for cooperating with the upper beveled portion 43 to move the first locking post 42 is formed at one end of the bottom of the second locking post 45. A locking limit block 46 is formed at the top end of the second locking post 45. A rounded corner portion 47 for cooperating with the moving base 10 to make the second locking post 45 contract downward is formed at the top end of the locking limit block 46. The second locking post 45 is the trigger end of the unlocking mechanism 39; a locking receiving groove 2 for the second locking post 45 to move is formed at the bottom of the workbench 1. A locking limit groove 3 for cooperating with the locking limit block 46 to limit the movement of the second locking post 45 is formed at the top of the locking receiving groove 2.

[0066] When the cylindrical barrel 13 at the front end of the moving platform 9 contacts the long iron sheet 60, after the bottom of the moving base 10 contacts the rounded corner portion 47, the second locking post 45 is limited to move downward under the action of the locking limit block 46. The downward moving second locking post 45 presses the upper beveled portion 43 through the lower beveled portion 48 at the bottom to make the first locking post 42 retract, thus completing the unlocking of the telescopic mechanism 49.

[0067] In order to solve the problem of how the telescopic end of the telescopic mechanism 49 extends and retracts, the following features are specifically set:

[0068] A first limit groove 4 for limiting is formed at the bottom of the workbench 1. The telescopic mechanism 49 includes a fixed sliding groove 50 fixedly arranged at the bottom end of the workbench 1 and perpendicular to the length side of the workbench 1. One end of the fixed sliding groove 50 contacts the receiving box 40 to make the first locking post 42 extend into the interior of the fixed sliding groove 50. The fixed sliding groove 50 includes: two groups of first springs 51, fixedly arranged in the middle of the inner side of the fixed sliding groove 50. Each group of first springs 51 is arranged along the length side direction of the fixed sliding groove 50 and extends outward; two telescopic plates 52, each telescopic plate 52 is sleeved on one end of a group of first springs 51 extending outward. A row of equally spaced locking holes 53 is formed on one side of each telescopic plate 52 facing the receiving box 40. A first limit block 54 for cooperating with the first limit groove 4 to limit the movement of the telescopic plate 52 is formed at the top end of each telescopic plate 52. The telescopic plate 52 is the telescopic end of the telescopic mechanism 49.

[0069] After the front end of the second locking post 45 disengages from the locking hole 53, the telescopic plate 52 in the fixed chute 50 moves outward under the action of the first spring 51, and the movement of the telescopic plate 52 is limited by the cooperation of the first limiting block 54 and the first limiting groove 4.

[0070] To solve the problems of how the telescopic mechanism 49 clamps the long iron sheet 60 and how to end the clamping of the long iron sheet 60, the following features are specifically set:

[0071] A second limiting groove 5 for limiting is formed at the bottom of the workbench 1, and the telescopic mechanism 49 further includes:

[0072] Two connecting blocks 55, each connecting block 55 is fixedly arranged at the outer side end of the telescopic plate 52 parallel to the length side direction of the workbench 1, and a second limiting block 56 for limiting the movement of the connecting block 55 is formed at the end of the connecting block 55 away from the telescopic plate 52 and is matched with the second limiting groove 5;

[0073] Two support columns 57, both of which are fixedly arranged vertically at the end of the connecting block 55 away from the telescopic plate 52;

[0074] Two clamping plates 58, both of which are fixedly arranged vertically at the top of the support column 57, and a clamping groove 59 for clamping the long iron sheet 60 is formed at the top of each clamping plate 58 and extends inward.

[0075] The telescopic plate 52 drives the connecting block 55 to move outward, the second limiting block 56 and the second limiting groove 5 cooperate to limit the movement of the connecting block 55, the connecting block 55 drives the clamping plate 58 on the support column 57 to move outward, and the clamping plate 58 releases the clamping of the long iron sheet 60, so that the long iron sheet 60 can move inside the correction welding box 26 under the extrusion of the moving platform 9.

[0076] To solve the problem of how the correction mechanism 27 corrects the long iron sheet 60, the following features are specifically set:

[0077] The correction mechanism 27 includes two groups of correction components 28 respectively fixedly arranged in the middle of the inner walls on both sides of the correction welding box 26. Each group of correction components 28 includes a plurality of correction sleeves 29. Each correction sleeve 29 includes a lower fixing plate 31 fixedly arranged at the bottom of the inner wall of the correction welding box 26. A vertical shaft column 32 is formed at the top of the other end of the lower fixing plate 31. A roller 33 for correcting the long iron sheet 60 is sleeved on the shaft column 32. Each correction sleeve 29 further includes an upper fixing plate 30 fixedly arranged at the top of the inner wall of the correction welding box 26 for fixing the shaft column 32. The lengths of the upper fixing plate 30 and the lower fixing plate 31 in each correction sleeve 29 increase along the feeding direction of the moving platform 9.

[0078] A drum 33 is sleeved on a shaft column 32 so that the drum 33 can rotate. The cylindrical barrel 13 and the drum 33 cooperate to fold and correct a long iron sheet 60. As the moving platform 9 continuously moves into the correction welding box 26, the drum 33 will squeeze the long iron sheet 60, making it slowly fit on both sides of the upper triangular piece 25 and the lower triangular piece 14.

[0079] To solve the problem of how the correction limiting component 34 limits the long iron sheet 60 being corrected, the following features are specifically set:

[0080] The correction limiting component 34 includes an upper limiting plate 35 and a lower limiting plate 37 that cooperates with the upper limiting plate 35 to limit the correction of the long iron sheet 60. An avoidance groove 36 through which the pressing plate 18 passes is formed in the middle of the upper limiting plate 35.

[0081] The distance between the upper limiting plate 35 and the lower limiting plate 37 is the same as the height of the long iron sheet 60. During the folding and correction process of the long iron sheet 60, the upper limiting plate 35 and the lower limiting plate 37 in close contact with the long iron sheet 60 ensure that the folding and correction do not occur misalignment, playing a role in limiting and correcting, and ensuring the smooth completion of the welding work.

[0082] A method for using a special-shaped part welding limiting workbench of a powder tank truck includes the following steps:

[0083] S1: The staff starts the lifting component 15. The threaded sleeve 19 drives the upper lifting block 17 to rise. When the threaded sleeve 19 rises to a certain height, the threaded sleeve 19 will drive the lower lifting block 21 to continue rising, and the special-shaped part correction table 24 also rises together with the lower lifting block 21.

[0084] S2: After the equipment rises, the staff places the cylindrical barrel 13, the upper triangular piece 25 and the lower triangular piece 14 on the equipment. The staff adjusts the length of the telescopic plate 52 to expand and contract outward through the first locking column 42 and the locking hole 53 to adapt to long iron sheets 60 of different lengths. After the adjustment of the locking hole 53 is completed, the staff inserts the long iron sheet 60 into the clamping groove 59 of the two clamping plates 58, and starts the lifting component 15 again. The threaded sleeve 19 starts to drive the upper lifting block 17 and the lower lifting block 21 to move downward, and finally stops descending when the lower lifting block 21 presses on the lower triangular piece 14 and the pressing plate 18 presses on the upper triangular piece 25, completing the fixing work of the welding parts.

[0085] S3: Start the first lead screw slide table 8. When the frontmost cylindrical barrel 13 touches the long iron sheet 60, the bottom of the moving base 10 touches the rounded corner part 47, causing the second locking post 45 to move downward. The downward-moving second locking post 45 presses the upper bevel part 43 through the lower bevel part 48, causing the first locking post 42 to retract inward, disengaging from the locking hole 53. The telescopic plate 52 moves outward under the action of the first spring 51, drives the clamping plate 58 to move outward through the connecting block 55, and releases the clamping of the long iron sheet 60.

[0086] S4: The moving platform 9 abuts against the long iron sheet 60 and continues to move into the inside of the correction welding box 26. The rollers 33 on the correction assembly 28 cooperate with the cylindrical barrel 13 to correct and fold the long iron sheet 60, making it finally fit on both sides of the upper triangular piece 25 and the lower triangular piece 14. During the correction process, the upper limit plate 35 and the lower limit plate 37 cooperate to limit the long iron sheet 60 being corrected, ensuring the accuracy of the correction.

[0087] S5: After the correction is completed, the staff welds the long iron sheet 60 to the cylindrical barrel 13, the upper triangular piece 25, and the lower triangular piece 14 through the upper welding groove 38 and the lower welding groove 6. After the welding is completed, start the equipment. After moving to the initial position, start the lifting assembly 15 to drive the special-shaped part correction table 24 to rise. At this time, the special-shaped parts will follow the special-shaped part correction table 24 to rise. When the cylindrical barrel 13 detaches from the fixed column 12, take the special-shaped parts off the special-shaped part correction table 24 to complete the entire welding operation.

[0088] Working principle: The staff starts the second lead screw slide table 16. The threaded sleeve 19 drives the pressing plate 18 to rise through the upper lifting block 17. When the threaded sleeve 19 rises to a certain height, the top of the convex ring 20 contacts the top of the lifting limit groove 22, driving the lower lifting block 21 to continue rising. The special-shaped part correction table 24 also rises together with the lower lifting block 21.

[0089] After the equipment rises, the staff sleeved the cylindrical barrel 13 on the fixed column 12, placed the upper triangular piece 25 on the special-shaped part correction table 24, and placed the lower triangular piece 14 on the support platform 11. The staff adjusted the outward telescopic length of the telescopic plate 52 by inserting the first locking post 42 into different locking holes 53, so that the two clamping plates 58 can clamp long iron sheets 60 of different lengths. After the adjustment of the locking hole 53 is completed, the staff inserted the long iron sheet 60 into the clamping grooves 59 of the two clamping plates 58, and started the second lead screw slide table 16 again. The threaded sleeve 19 began to drive the upper lifting block 17 to move downward. The lower lifting block 21 moved downward following the threaded sleeve 19 under the action of gravity. When the lower lifting block 21 dropped to the lowest point, it just pressed on the lower triangular piece 14 to complete the fixing of the parts. The threaded sleeve 19 drove the upper lifting block 17 to continue to drop until it stopped dropping when the pressing plate 18 pressed on the upper triangular piece 25 to complete the fixing work of the welding parts.

[0090] Start the first lead screw slide table 8, and move the platform 9 towards the correction welding box 26. When the cylindrical barrel 13 at the forefront of the moving platform 9 contacts the long iron sheet 60, the bottom of the moving base 10 causes the second locking post 45 to move downward through the rounded corner portion 47. The downward-moving second locking post 45 presses the upper bevel portion 43 through the lower bevel portion 48, causing the first locking post 42 to retract inward, disengaging from the locking hole 53. The telescopic plate 52 moves outward under the action of the first spring 51, driving the clamping plate 58 to move outward through the connecting block 55, releasing the clamping of the long iron sheet 60.

[0091] The moving platform 9 abuts against the long iron sheet 60 and continues to move into the correction welding box 26. The rollers 33 on the correction assembly 28 cooperate with the cylindrical barrel 13 to correct and fold the long iron sheet 60, making it finally fit on both sides of the upper triangular piece 25 and the lower triangular piece 14. During the correction process, the upper limit plate 35 and the lower limit plate 37 cooperate to limit the long iron sheet 60 being corrected, ensuring the accuracy of the correction.

[0092] After the correction is completed, the staff welds the long iron sheet 60 to the cylindrical barrel 13, the upper triangular piece 25, and the lower triangular piece 14 through the upper welding groove 38 and the lower welding groove 6. After the welding is completed, start the first lead screw slide table 8, and the moving platform 9 takes out the welded special-shaped parts from the correction welding box 26. After moving to the initial position, start the second lead screw slide table 16. The threaded sleeve 19 drives the pressing plate 18 to rise through the upper lifting block 17. When the threaded sleeve 19 rises to a certain height, the convex ring 20 contacts the top of the lifting limit groove 22, driving the special-shaped part correction table 24 to rise through the lower lifting block 21. At this time, the special-shaped parts will follow the special-shaped part correction table 24 to rise. When the cylindrical barrel 13 disengages from the fixed column 12, take down the special-shaped parts from the special-shaped part correction table 24 to complete the entire welding operation.
