Description

Technical Field

[0001] This utility model relates to the field of pressure vessel processing, specifically to a head positioning and welding device. Background Technology

[0002] Pressure vessels are generally composed of a cylindrical body and end caps at both ends, which are fixed together by welding.

[0003] In the prior art, utility model patent application number CN202421751909.6 discloses an auxiliary tooling for welding end caps and cylinders for processing air compressor tanks. A rotatable rotating rod is installed through the top of one side of the vertical plate, and a cover is fixedly connected to the right end of the rotating rod. A cylinder is fixedly installed on the top of the right side of the vertical plate, and a connecting block is fixedly installed at the output end of the cylinder. A cover is rotatably connected to the left side of the connecting block. Covers 1 and 2 are symmetrically arranged. Two end cap bodies and cylinder bodies are arranged between cover 1 and cover 2. An adjustable support assembly is provided on the rear side of the top of the bottom plate, and a movable welding gun is provided on the adjustable support assembly.

[0004] The aforementioned welding auxiliary fixture clamps the cylinder and the end caps at both ends using cover one and cover two, and drives the end caps and cylinder to rotate electrically, so that the welding torch can weld the cylinder and end caps at a uniform speed, ensuring welding efficiency and welding quality.

[0005] However, the aforementioned welding auxiliary tooling lacks a structure to support the cylinder, leaving the bottom of the cylinder suspended in the air. This makes it inconvenient to assemble and match the cylinder and the end cap before welding, and makes it impossible to efficiently install the cylinder and the end cap between the first and second sleeve covers. Utility Model Content

[0006] The purpose of this invention is to provide a head positioning and welding device, which makes the assembly of the cylinder and the head more convenient, thereby solving the defects mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] The head positioning and welding device includes a long strip-shaped base plate. Two sets of head fixing assemblies are arranged opposite each other along the length of the base plate. A cylinder support assembly is located on the base plate between the two sets of head fixing assemblies. Each head fixing assembly includes a movable frame driven by a power device and moving along the length of the base plate. A support seat is fixedly installed on the movable frame. An annular plate for pressing the head is fixedly installed on the side of the support seat near the cylinder support assembly. An extension rod is also fixedly installed on the support seat, and an electromagnet for attracting the head is fixedly installed on the extension rod.

[0009] As a further improvement, multiple extension rods are evenly spaced around the annular plate, and the multiple extension rods are radially distributed around the annular plate, with the end of the extension rod away from the annular plate inclined toward the side closer to the cylinder support assembly.

[0010] As a further improvement, the movable frame includes a movable plate driven by the power unit and moving along the length direction of the base plate. A mounting frame is provided on the top of the movable plate. One end of the mounting frame is rotatably mounted on the movable plate. The axis of rotation of the mounting frame extends horizontally perpendicular to the length direction of the base plate. A telescopic component for driving the mounting frame to rotate is connected between the movable plate and the mounting frame. A sliding plate is slidably mounted on the mounting frame. The sliding direction of the sliding plate is perpendicular to the axis of rotation of the mounting frame. The support base is fixedly mounted on one side of the sliding plate.

[0011] As a further improvement, a guide rail is fixedly installed on one side of the mounting bracket, the guide rail being perpendicular to the axis of rotation of the mounting bracket, and the slide plate is slidably installed on the guide rail; a lead screw driven to rotate by an adjusting motor is also installed on the mounting bracket, the lead screw being arranged parallel to the guide rail, and a lead nut matching the lead screw is fixedly installed on the slide plate.

[0012] As a further improvement, the cylinder support assembly includes a U-shaped frame fixedly installed on the top of the base plate, and two rollers arranged side by side along the width direction of the base plate are rotatably installed inside the U-shaped frame. The rollers extend along the length direction of the base plate, and one of the rollers is driven to rotate by a drive motor.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This application uses rollers to support the cylinder and a movable frame to engage the end cap with the cylinder, thus completing the assembly of the cylinder and the end cap, making the assembly of the cylinder and the end cap more convenient;

[0015] 2. This application adjusts the mounting bracket to a horizontal position, drives the support base to rotate to its top, then places the end cap on the top of the support base and attracts the end cap with an electromagnet, and then adjusts the mounting bracket to a vertical position so that the end cap is connected to the cylinder. When assembling the cylinder and the end cap, there is no need to manually handle the end cap.

[0016] 3. This application facilitates the rotation of the idler roller by driving the drive motor, which in turn drives the cylinder and end cap to rotate, thereby adjusting the angle between the cylinder and the end cap, making welding more convenient. Attached Figure Description

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] like Figures 1 to 5 As shown, the head positioning and welding device includes a base plate 1, which is a long strip extending laterally.

[0026] The base plate 1 is provided with two sets of end cap fixing components 2 arranged opposite each other along its length, and the base plate 1 between the two sets of end cap fixing components 2 is provided with a cylinder support component 3.

[0027] like Figure 2 As shown, the cylinder support assembly 3 includes a U-shaped frame 4 bolted to the top of the base plate 1. The U-shaped frame 4 has two vertical arms arranged opposite each other. Two rollers 5 are rotatably mounted between the two vertical arms of the U-shaped frame 4, arranged side by side along the width direction of the base plate 1. The rollers 5 extend left and right along the length direction of the base plate 1. The two rollers 5 can support the cylinder 29 that makes up the pressure vessel. One of the rollers 5 is driven to rotate by a drive motor 6. The drive motor 6 is bolted to the bottom wall of the U-shaped frame 4. The rotating shaft of the drive motor 6 is connected to the end of one of the rollers 5 by a belt 28. When welding the cylinder 29 and the end cap 30, the drive motor 6 can drive the corresponding roller 5 to rotate, and the roller 5 in turn drives the cylinder 29 to rotate, thereby adjusting the angle of the cylinder 29.

[0028] like Figure 3 and Figure 4 As shown, the head fixing assembly 2 includes a movable frame 7 driven by a power device and moving along the length of the base plate 1. The movable frame 7 includes a movable plate 8 driven by a power device and moving left and right along the length of the base plate 1. In this embodiment, two slide rails 9 arranged in parallel front and rear are fixedly installed on the top of the base plate 1. The slide rails 9 extend left and right along the length of the base plate 1. The movable plates 8 of the two sets of head fixing assemblies 2 are slidably installed on the two slide rails 9. The power device is specifically a first cylinder 10. Fixed plates 11 are fixedly installed at both ends of the top of the base plate 1. A first cylinder 10 is installed on the inner side of each of the two fixed plates 11 by bolts. The piston rods of the two first cylinders 10 extend towards each other and are fixedly connected to the corresponding movable plates 8 by bolts. The extension and retraction of the first cylinders 10 can drive the movable frame 7 to move closer to or away from the cylinder support assembly 3.

[0029] The top of the movable plate 8 is provided with a mounting frame 12, which includes two vertical rods 13 arranged opposite each other. The upper and lower ends of the two vertical rods 13 are respectively fixed with horizontal rods 14 by bolts. The lower end of the mounting frame 12 is rotatably mounted on the movable plate 8. The axis of rotation of the mounting frame 12 extends horizontally back and forth perpendicular to the length direction of the base plate 1. The top of the movable plate 8 is fixedly mounted with two hinge plates 15 arranged opposite each other. The lower ends of the two vertical rods 13 are respectively fixedly mounted on the opposite sides, and the hinge shafts 16 extend back and forth. The hinge shafts 16 are rotatably mounted on the corresponding hinge plates 15. A telescopic component for driving the mounting frame 12 to rotate is connected between the movable plate 8 and the mounting frame 12. The telescopic component is a second cylinder 17. One end of the second cylinder 17 is hinged to the movable plate 8 and the other end is hinged to the vertical rod 13 of the mounting frame 12. The second cylinder 17 extends to drive the mounting frame 12 to rotate towards the cylinder support assembly 3, or retracts to drive the mounting frame 12 to rotate away from the cylinder support assembly 3.

[0030] A sliding plate 18 is vertically slidably mounted on the side of the mounting bracket 12 near the cylinder support assembly 3. Two vertical rods 13 are respectively fixed to the side of the cylinder support assembly 3 by bolts, and a sliding seat 20 matching the guide rail 19 is fixedly mounted on the sliding plate 18 by bolts. A support seat 21 is fixedly mounted on the side of the sliding plate 18 near the cylinder support assembly 3 by bolts. An annular plate 22 for pressing the end cap 30 is fixedly mounted on the middle part of the support seat 21 near the cylinder support assembly 3 by bolts. An extension rod 23 is also fixedly mounted on the side of the support seat 21 near the cylinder support assembly 3. In this embodiment, multiple extension rods 23 are evenly spaced around the annular plate 22, and the multiple extension rods 23 are radially distributed around the annular plate 22. The end of the extension rod 23 away from the annular plate 22 is inclined towards the side near the cylinder support assembly 3. An electromagnet 24 for attracting the end cap 30 is embedded in the inner side of the end of the extension rod 23 away from the annular plate 22.

[0031] The mounting bracket 12 is also equipped with a lead screw 26 driven by the adjusting motor 25. The lead screw 26 is arranged parallel to the guide rail 19. The lower end of the lead screw 26 is rotatably mounted on the lower crossbar 14 through a bearing, and the upper end is connected to the motor shaft of the adjusting motor 25 through a coupling. The adjusting motor 25 is mounted on the upper crossbar 14 by bolts. A lead screw nut 27 matching the lead screw 26 is fixedly mounted on the slide plate 18 by bolts.

[0032] Initially, the mounting bracket 12 is in a vertical position. In use, the second cylinder 17 retracts, causing the mounting bracket 12 to rotate away from the cylinder support assembly 3 until it reaches a horizontal position. Figure 5As shown, the mounting bracket 12 drives the support base 21 to rotate to its top; then the cylinder 29 is placed horizontally on top of the two idler rollers 5, with both ends of the cylinder 29 extending beyond the ends of the two idler rollers 5; end caps 30 are placed on top of the two support bases 21 respectively, with the opening of the end caps 30 facing upwards on top of the annular plate 22, and the end caps 30 are evenly in contact with the electromagnets 24 on the multiple extension rods 23; after the end caps 30 are aligned, the electromagnets 24 are energized to attract the end caps 30, and then the second cylinder 17... The extension mechanism drives the mounting bracket 12 to rotate towards the cylinder support assembly 3 until it reaches a vertical position. The mounting bracket 12 then rotates the support base 21 and the end cap towards the side closest to the end cap fixing assembly 2. Next, the adjusting motor 25 drives the lead screw 26 to rotate, which in turn moves the sliding plate 18 up and down along the guide rail 19, thereby adjusting the height of the end cap 30 until it is adjusted to the same height as the cylinder 29. Finally, the first cylinder 10 extends the movable frame 7 towards the cylinder support assembly 3, as shown in the image. Figure 1 As shown, the movable frame 7 drives the end cap 30 to engage with the end of the cylinder 29, completing the assembly of the cylinder 29 and the end cap 30.

[0033] After the cylinder 29 and the end cap 30 are assembled, the workers first spot weld the end cap 30 and the cylinder 29 to pre-fix them. Then, the electromagnet 24 is de-energized, and the first cylinder 10 retracts to move the movable frame 7 away from the cylinder support assembly 3, so that the end cap 30 is separated from the support seat 21. Finally, the end cap 30 and the cylinder 29 are further welded. During the welding process, the drive motor 6 drives the roller 5 to rotate and adjusts the angle between the cylinder 29 and the end cap 30.

[0034] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model 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 utility model.
