Description

Technical Field

[0001] This invention relates to the field of workpiece welding positioning technology, specifically to a precision machining device that facilitates fixation. Background Technology

[0002] Steel plate welding is a processing technology that uses heating, pressurization, or a combination of both to form an atomic bond at the joint of two or more steel plates. It is widely used in construction, machinery, shipbuilding, steel structures and other fields, and its quality directly determines the strength, sealing performance and service life of the components.

[0003] In existing technologies, when welding steel plates, the welding joints are usually cut out on two steel plates first, and then the two steel plates are placed side by side under the welding machine before welding. This operation requires the operator to frequently pick up and place the steel plates, and the two steel plates need to be aligned, which reduces the welding efficiency of the steel plates. Furthermore, existing technologies do not have dedicated positioning welding equipment for steel plates. Therefore, we propose a precision machining device that is easy to fix to solve the above-mentioned defects. Summary of the Invention

Then, by the push ring that moves along with it, the two steel plates are adjusted from misalignment to a flush state and moved toward the welding position, which facilitates the positioning and alignment of the steel plates.

[0017] In this invention, two steel plates are oscillated relative to each other by a horizontal frame and a through-hole lever, so that the cuts of the two steel plates are brought closer to each other. Then, the weld distance of the steel plates is adjusted by the movement of the U-shaped plate. After the limiting block clamps the steel plates, the steel plates are welded.

Detailed Implementation

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] Please see Figures 1 to 10 The present invention provides a technical solution: including a main unit 1, a drive slide rail 2 symmetrically arranged in the middle of the main unit 1, a platform 9 driven on the drive slide rail 2, the platform 9 being slidably connected to the drive slide rail 2, a fixed inner support frame 3 fixedly connected to the main unit 1 on both sides of the drive slide rail 2, a plurality of screws 4 slidably arranged on both sides of the fixed inner support frame 3, the screws 4 being rotatably arranged on the adjustment frame 5, a material frame 6 being screwed to one end of the screws 4 that is close to each other, the material frame 6 being slidably connected to the fixed inner support frame 3, an L-rod 7 being arranged on the inner side of the fixed inner support frame 3, the L-rod 7 being symmetrically arranged on the material frame 6, and a material picking hole 8 being arranged between the L-rod 7, the two sides of the material picking hole 8 being through;

[0031] A telescopic rod 10 is fixedly connected to the bottom of one end of the platform 9, and a first inclined wedge 11 is fixedly connected to the other end of the telescopic rod 10. A control spring 12, which is movably sleeved outside the telescopic rod 10, is abutted against the bottom of the first inclined wedge 11. The width of the first inclined wedge 11 is smaller than the width of the material picking opening 8.

[0032] When this device is in operation, firstly, steel plates to be welded are batched into the material frame 6. If the cut of the steel plate has a beveled welding port, the beveled welding ports need to be uniformly arranged on one side. By rotating the screw 4, the material frame 6 is loosened, and the relative distance between the material frame 6 and the L rod 7 can be adjusted to accommodate different steel plate thicknesses, so that the bottom of the material frame 6 and the L rod 7 are kept at the height of two steel plates. Then, the platform 9 is controlled to slide from the first end to the last end by driving the slide rail 2. During the process, the first wedge 11 is in the released state and contacts the end faces of the two steel plates. During the movement of the platform 9, the first wedge 11 pushes the two steel plates to move from the L rod 7 and slides them onto the platform 9. At this time, the steel plates are located between the two stop rods 13, and the platform 9 as a whole moves away from below the material frame 6.

[0033] The platform 9 is symmetrically and fixedly equipped with stop rods 13 on both sides. A push rod 14 that is slidably connected to the platform 9 is provided between the two stop rods 13. A return spring 15 is movably sleeved at the connection between the push rod 14 and the platform 9. The bottom of the push rod 14 passes through the platform 9 and is fixedly connected to a base plate 16. A connecting port 17 is opened laterally on the base plate 16.

[0034] A rack 18 is fixedly installed in the middle of one of the drive slide rails 2. A gear 19 is rotatably connected to the bottom of the platform 9. The gear 19 meshes with the rack 18. An eccentric block 20 is fixedly connected to the top of the gear 19 off-center. A swing arm 21 is hinged to one end of the bottom of the platform 9. An adapter port 22 is opened through the middle of the swing arm 21. The eccentric block 20 is slidably disposed in the adapter port 22. The end of the swing arm 21 that is connected to the platform 9 is slidably disposed in the connection port 17.

[0035] Two distribution plates 23 are respectively installed on the outside of the two drive slide rails 2 on the main unit 1. A truss 24 is installed on the top of the main unit 1. A boom 25 is slidably installed on the truss 24. A contact block 26 is symmetrically and fixedly connected to the bottom of the boom 25. Push rings 27 are symmetrically and fixedly connected to both sides of the boom 25. Blocks 28 are fixedly connected around the platform 9. The blocks 28 abut against the contact blocks 26.

[0036] When the two steel plates are on platform 9, the gear 19 at the bottom of platform 9 meshes with the rack 18, and the gear 19 is rotated by the meshing. During this process, the eccentric block 20, which is offset from the axis of gear 19, rotates and drives the swing arm 21 to swing. The swing arm 21 swings back and forth continuously at the bottom of platform 9 with its connection point with platform 9 as the axis. During this process, the other end of the swing arm 21 slides in the connection port 17, thereby driving the flat push rod 14 to move to one side through the base plate 16. The flat push rod 14 pushes one of the bottom steel plates to the side, causing the return spring 15 to... The bottom steel plate is compressed and pushed onto one of the distribution plates 23. During the process of the bottom steel plate being pushed, the top steel plate is blocked by the stop rods 13 on both sides and does not move with the bottom steel plate. After the push rod 14 moves to the other side of the platform 9, the gear 19 continues to rotate, causing the swing arm 21 to swing back and drive the push rod 14 back to its original position. Previously, because the bottom steel plate was pushed onto the distribution plate 23, the top steel plate automatically fell down and contacted the surface of the platform 9. It was pushed onto the opposite distribution plate 23 by the returned push rod 14, and the top steel plate fell onto another distribution plate 23.

[0037] Due to a time error in the landing of the two steel plates on the distribution plate 23, the two steel plates are misaligned and positioned one in front of the other. Prior to this, when the platform 9 moves from the bottom of the material frame 6, it abuts against the contact block 26 through the stop block 28, causing the boom 25 to be pushed and slide to the other side of the truss 24. When the bottom steel plate is pushed onto the distribution plate 23, the push ring 27 following the direction of movement of the platform 9 contacts the steel plate and pushes it forward. After the top steel plate is pushed onto the distribution plate 23, another push ring 27 contacts it and pushes the steel plate in the same way, so that the two steel plates, after being misaligned, move forward again in a level state.

[0038] A telescopic arm 29 is provided at the end of the truss 24 away from the material frame 6, and a welding machine 30 is fixedly connected to the bottom of the telescopic arm 29.

[0039] One end of the distribution plate 23 is rotatably connected to the bearing plate 31. The height of the bearing plate 31 is lower than the height of the other end of the distribution plate 23. Several symmetrically arranged limiting blocks 32 are slidably arranged on the bearing plate 31. The side of the limiting block 32 passes through the bearing plate 31 and is fixedly connected to the output shaft of the electric cylinder 33. The electric cylinder 33 is fixedly installed on the side wall of the bearing plate 31.

[0040] The bottom of the bearing plate 31 passes through the distribution plate 23 and is fixedly connected to the rotating shaft 34. A through-hole lever 35 is fixedly connected to the rotating shaft 34. A horizontal frame 36 is slidably arranged inside the through-hole lever 35. The bottom of the horizontal frame 36 is slidably connected to the main unit 1.

[0041] A lifting rod 37 is slidably provided at the end of the platform 9. The lifting rod 37 passes through the platform 9 and is fixedly connected to the bottom of the platform 9 with a second inclined wedge 38.

[0042] Servo motors 39 are symmetrically installed on both sides of the main unit 1. The output shaft of the servo motor 39 passes through the main unit 1 and is screwed with a U-shaped plate 40. The U-shaped plate 40 is slidably connected to the main unit 1 and passes through the support plate 31.

[0043] Platform 9 drives the push ring 27 to move, transferring the two steel plates from the distribution plate 23 to the surface of the bearing plate 31. At this time, the second wedge 38 at the bottom of platform 9 passes over the horizontal frame 36 and falls down, with the side of the second wedge 38 contacting the horizontal frame 36. At this time, the drive rail 2 controls platform 9 to return to its original position. During this process, the second wedge 38 pulls the horizontal frame 36, causing it to move accordingly. As the horizontal frame 36 moves, it slides within the two through-hole levers 35, causing the through-hole levers 35 to rotate around the rotating shaft 34. At this time, the bearing plate 31, which is fixedly connected to the rotating shaft 34, rotates synchronously, causing the two steel plates to symmetrically flip outward by ninety degrees. Subsequently, platform 9 stops moving, and the two steel plates cut... After the openings are flipped, they become opposite, which is the welding joint. Then, the servo motor 39 is started, driving the U-shaped plate 40 to move towards the center of the main unit 1. The U-shaped plate 40 passes through the support plate 31, contacts the end of the steel plate opposite to the welding joint, and pushes the steel plates closer to each other. After the position is adjusted, the electric cylinder 33 is started, driving each group of four limit blocks 32 to support the side of the steel plate to clamp it, so that the steel plate is fixed on the support plate 31. Then, the telescopic arm 29 controls the welding machine 30 to descend and weld between the two steel plates. After the welding is completed, the operator removes the steel plate, pulls up the lifting rod 37, so that the second wedge 38 is disconnected from the horizontal frame 36, and pushes the horizontal frame 36 back, so that the two support plates 31 rotate.

[0044] The method of use and advantages of this invention: This precision machining device, which is easy to fix, operates as follows:

[0045] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 , Figure 10 As shown:

[0046] S1: Place the steel plate into the material frame 6 and align the weld joint. Adjust the screw 4 to match the thickness of the steel plate. Drive the slide rail 2 to move the platform 9. The first wedge 11 pushes the two steel plates to slide down onto the platform 9, located between the stop bars 13.

[0047] S2: When the platform 9 moves, the gear 19 meshes with the rack 18 and rotates. The eccentric block 20 drives the swing arm 21 to swing. The flat push rod 14 first pushes the bottom steel plate to the distribution plate 23 on one side, and then returns to its original position to push the top steel plate to another distribution plate 23.

[0048] S3: When the two steel plates are misaligned, the platform 9 moves while the stop block 28 pushes the boom 25 and the push ring 27 to contact the two steel plates one after the other, so that they are realigned and move forward synchronously.

[0049] S4: When the steel plate moves to the bearing plate 31 and the platform 9 returns to its original position, the second wedge 38 pulls the horizontal frame 36, causing the bearing plate 31 to flip so that the welding joints of the two steel plates are facing each other. The U-shaped plate pushes the steel plates closer together, the limiting block 32 clamps the steel plates, and the welding machine 30 welds the connection between the two steel plates.

[0050] In this invention, by driving the platform 9 to move towards the welding position, the first wedge 11 removes two arranged steel plates from the L rod 7, so that the steel plates automatically fall onto the platform 9 and move towards the welding position to realize automatic delivery of the steel plates to the welding position. Furthermore, by adjusting the relative position of the screw 4 and the material frame 6, the space exposed at the bottom of the material frame 6 can be adjusted, which is suitable for steel plates of different thicknesses.

[0051] In this invention, the flat push rod 14 moves back and forth continuously during the movement process. First, it pushes the bottom steel plate onto the distribution plate 23. Then, by returning to its original position, it pushes another steel plate onto the opposite distribution plate 23, so that the two steel plates are separated. Then, by the push ring 27 that moves along with it, the two steel plates are adjusted from misalignment to a flush state and moved toward the welding position, which facilitates the positioning of the steel plates and the alignment of the steel plates.

[0052] In this invention, the two steel plates are swung relative to each other by the horizontal frame 36 and the through-hole lever 35, so that the cuts of the two steel plates are brought closer to each other. Then, the weld distance of the steel plates is adjusted by the movement of the U-shaped plate 40. After the limiting block 32 clamps the steel plates, the steel plates are welded.

[0053] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the invention.
