Description

Technical Field

[0001] This utility model belongs to the field of shielding cylinder technology, specifically a shielding cylinder welding fixture with a calibration function. Background Technology

[0002] A shielding cylinder is a protective device to prevent interference and contamination. It is a cylindrical shield made of conductive, magnetic, or specific materials, used to limit electromagnetic fields, prevent metal vapor and liquid droplet splashes, and provide an interference-free or protected environment.

[0003] Existing shielding cylinder welding methods mostly employ a casting-welding combination process. The lower part is formed by low-pressure casting, while the upper part is a pre-formed tube. After insertion and welding, the contact surfaces of the components are melted, filler material is added, and a strong connection is formed after cooling. However, during the insertion and welding process, if the concentricity of the upper and lower components is not properly aligned, defects may appear in the welded shielding cylinder, affecting the welding effect. Additionally, if the upper and lower components are not fully inserted and welded without correction, the upper surface of the welded shielding cylinder may be tilted, further impacting the welding effect.

[0004] To address this, a shielded cylindrical welding fixture with a calibration function is proposed. Utility Model Content

[0005] The purpose of this utility model is to provide a shielding cylinder welding fixture with a correction function in order to improve the welding effect of the shielding cylinder.

[0006] The technical solution adopted in this utility model is as follows:

[0007] A shielded cylindrical welding fixture with a correction function includes a base plate, a U-shaped plate fixedly connected to the upper surface of the base plate, a placement platform and a rotating mechanism installed on the upper surface of the base plate between the U-shaped plate and the inner sidewall, two lower clamping mechanisms symmetrically installed on the upper surface of the rotating mechanism, a correction mechanism installed between the upper end of the U-shaped plate and the inner sidewall, and an upper clamping mechanism installed at the lower end of the correction mechanism.

[0008] The correction mechanism includes an upper motor, which is fixedly connected to the inner wall of the upper right side of the U-shaped plate. A lead screw is fixedly connected to the output end of the upper motor. The end of the lead screw away from the upper motor is rotatably connected to the inner wall of the upper left side of the U-shaped plate through a bearing. A movable plate is threadedly connected to the outer surface of the lead screw. An upper electric cylinder is fixedly connected to the lower surface of the movable plate. An upper piston rod is installed on the lower surface of the upper electric cylinder.

[0009] The upper clamping mechanism includes a connecting column, which is fixedly connected to the end of the upper piston rod away from the upper electric cylinder. A double cylinder is fixedly connected to the lower surface of the connecting column. A left piston rod is installed on the left side of the double cylinder, and a right piston rod is installed on the right side of the double cylinder. An arc-shaped clamping plate one is fixedly connected to the outer surface of the end of the left piston rod away from the double cylinder, and an arc-shaped clamping plate two is fixedly connected to the outer surface of the end of the right piston rod away from the double cylinder. A fixing plate is fixedly connected to the middle of the inner sidewalls of the arc-shaped clamping plate one and the arc-shaped clamping plate two. A movable limiting plate is fixedly connected to the right outer surface of the arc-shaped clamping plate two, and a fixed limiting plate is fixedly connected to the inner sidewall of the right end of the U-shaped plate.

[0010] The rotating mechanism includes a lower motor, which is fixedly connected to the upper surface of the base plate. A rotating rod is fixedly connected to the output end of the lower motor, and a turntable is fixedly connected to the end of the rotating rod away from the lower motor.

[0011] Furthermore, a limiting groove is formed on the lower surface of the upper end of the U-shaped plate, and the inner surface of the limiting groove is slidably connected to the outer surface of the upper end of the movable plate.

[0012] Furthermore, the lower clamping mechanism includes two vertical plates, which are fixedly connected to both ends of the upper surface of the turntable. A lower electric cylinder is fixedly connected to one side of the two vertical plates that are close to each other. A lower piston rod is installed on the side of the lower electric cylinder that is away from the vertical plates. An arc-shaped clamping plate is fixedly connected to the side of the lower piston rod that is away from the lower electric cylinder.

[0013] Furthermore, the placement platform is fixedly connected to the upper surface of the base plate, and a placement groove is formed on the upper surface of the placement platform.

[0014] Furthermore, the curvature of the first and second arc-shaped clamping plates is adapted to the curvature of the upper cylinder of the shielding tube, and the curvature of the third arc-shaped clamping plate is adapted to the curvature of the lower cylinder of the shielding tube.

[0015] Furthermore, the input terminals of the upper motor, the upper electric cylinder, the lower motor, and the lower electric cylinder are electrically connected to an external power source.

[0016] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0017] In this invention, when welding the upper and lower cylinders of the shielding cylinder, the lower cylinder can be clamped first using the lower clamping mechanism, and then the upper cylinder can be clamped using the upper clamping mechanism. When clamping the upper cylinder, the upper cylinder is first placed on the placement platform, and then the first and second arc-shaped clamping plates are placed on both sides of the upper cylinder. Then, the double cylinder is activated, causing the left piston rod and the first and second arc-shaped clamping plates to move closer to the outer surface of the upper cylinder. Simultaneously, the upper electric cylinder is activated, causing the upper piston rod to move the upper clamping mechanism downwards until the upper surface of the upper cylinder abuts against the lower surface of the fixed plate. Then, the continuously approaching arc-shaped clamping plates hold the upper cylinder in place. Next, the upper motor is activated to rotate the lead screw. At this time, the moving plate can move to the right under the rotation of the lead screw until the movable limit plate and the U-shaped plate... The inner wall of the right end of the forming plate abuts against each other, thus ensuring the concentricity of the upper and lower cylinders of the shielding tube. This allows for the correction and control of the concentricity during the welding of the upper and lower cylinders. Next, the upper cylinder is moved downwards by the upper electric cylinder and upper piston rod until its lower end inserts into the lower cylinder. At this point, the upper surface of the movable limiting plate abuts against the upper surface of the fixed limiting plate, allowing for welding at the insertion point of the upper and lower cylinders. This corrects and controls the height of the shielding tubes after welding in the same batch. Simultaneously, the lower motor can be activated to rotate the rotating rod, which in turn rotates the clamped lower cylinder, aligning it with the corresponding insertion position of the upper cylinder for easier welding and improved welding results. The combined effect of these structures enhances the welding performance of the shielding tubes. Attached Figure Description

The curvature of the arc-shaped clamping plate 74 is adapted to the curvature of the lower cylinder of the shielding tube. Specifically, when welding the upper and lower cylinders of the shielding tube, the lower cylinder of the shielding tube is first placed on the rotating mechanism 6. Then, the two lower electric cylinders 72 are activated to make the lower piston rod 73 drive the arc-shaped clamping plate 74 to move closer to the lower cylinder of the shielding tube and clamp the lower cylinder.

A fixing limiting plate 32 is fixedly connected to the inner right side of the U-shaped plate 3. Specifically, the upper cylinder of the shielding tube is placed inside the placement groove 21, and then the first arc-shaped clamping plate 54 and the second arc-shaped clamping plate 56 are placed on both sides of the upper cylinder of the shielding tube. Then, the double cylinder 52 is activated to make the left piston rod 53 and the first arc-shaped clamping plate 54 move the first arc-shaped clamping plate 54 and the second arc-shaped clamping plate 56 closer to the outer surface of the upper cylinder of the shielding tube, in preparation for clamping.

A lead screw 42 is fixedly connected to the output end of the upper motor 41. The end of the lead screw 42 away from the upper motor 41 is rotatably connected to the inner wall of the upper left side of the U-shaped plate 3 via a bearing.

The upper cylinder of the shielding cylinder is clamped by the continuously approaching arc-shaped clamping plates 54 and 56; then the upper motor 41 can be started to rotate the lead screw 42. At this time, the moving plate 43 can move to the right under the action of the rotation of the lead screw 42. The upper end of the moving plate 43 will slide along the inner surface of the limiting groove 31 until the movable limiting plate 57 abuts against the inner wall of the right end of the U-shaped plate 3, thereby ensuring the concentricity of the upper and lower cylinders of the shielding cylinder. The concentricity of the welding of the cylinder body is corrected and controlled. Then, the upper cylinder body of the shielding cylinder can be moved downward by the upper electric cylinder 44 and the upper piston rod 45 until the lower end of the upper cylinder body of the shielding cylinder is inserted into the lower cylinder body of the shielding cylinder. At this time, the upper surface of the movable limit plate 57 will just abut against the upper surface of the fixed limit plate 32. Then, the insertion point of the upper and lower cylinder bodies of the shielding cylinder can be welded, thereby correcting and controlling the height of the shielding cylinders after welding in the same batch, thereby improving the welding effect of the shielding cylinder.

[0027] Reference Figures 1-4 The rotating mechanism 6 includes a lower motor 61, which is fixedly connected to the upper surface of the base plate 1. A rotating rod 62 is fixedly connected to the output end of the lower motor 61, and a turntable 63 is fixedly connected to the end of the rotating rod 62 away from the lower motor 61. Specifically, by starting the lower motor 61, the rotating rod 62 drives the turntable 63 to rotate, which in turn drives the lower body of the shielding cylinder to rotate, so as to correct the lower body of the shielding cylinder to the corresponding insertion position with the upper body of the shielding cylinder, which facilitates welding and improves the welding effect of the shielding cylinder. The combination of the above structures can improve the welding effect of the shielding cylinder.

[0028] Reference Figures 1-4The input terminals of the upper motor 41, upper electric cylinder 44, lower motor 61, and lower electric cylinder 72 are electrically connected to an external power source; specifically, the external power source can provide power for starting the upper motor 41, upper electric cylinder 44, lower motor 61, and lower electric cylinder 72.

[0029] The implementation principle of a shielded cylindrical welding fixture with correction function according to this application is as follows:

[0030] When using this device, first connect an external power source. When welding the upper and lower cylinders of the shielding cylinder, first place the lower cylinder of the shielding cylinder on the turntable 63. Then, start the two lower electric cylinders 72 to make the lower piston rod 73 drive the arc-shaped clamping plate 74 to move closer to the lower cylinder of the shielding cylinder and clamp it. Next, place the upper cylinder of the shielding cylinder inside the placement groove 21. Then, place the arc-shaped clamping plate 54 and the arc-shaped clamping plate 56 on both sides of the upper cylinder of the shielding cylinder. Then, start the double cylinder 52 to make the left piston rod 53 and the arc-shaped clamping plate 54 move closer to the outer surface of the upper cylinder of the shielding cylinder. At the same time, start the upper electric cylinder 44 to make the upper piston rod 45 drive the upper clamping mechanism 5 to move downward until the upper surface of the upper cylinder of the shielding cylinder abuts against the lower surface of the fixed plate 55. Then, use the constantly approaching arc-shaped clamping plates 54 and 56 to clamp the upper cylinder of the shielding cylinder.

[0031] Next, the upper motor 41 can be started to rotate the lead screw 42. At this time, the moving plate 43 can move to the right under the rotation of the lead screw 42. The upper end of the moving plate 43 will slide along the inner surface of the limiting groove 31 until the movable limiting plate 57 abuts against the inner wall of the right end of the U-shaped plate 3, thereby ensuring the concentricity of the upper and lower cylinders of the shielding cylinder and correcting and controlling the concentricity of the welding of the upper and lower cylinders of the shielding cylinder. Then, the upper electric cylinder 44 and the upper piston rod 45 can be used to drive the upper cylinder of the shielding cylinder to move downward until the lower end of the upper cylinder of the shielding cylinder is aligned with the lower cylinder of the shielding cylinder. When the upper surface of the movable limiting plate 57 is inserted, it will abut against the upper surface of the fixed limiting plate 32. At this time, the upper and lower cylinders of the shielding tube can be welded, thereby correcting and controlling the height of the shielding tubes after welding in the same batch. At the same time, the lower motor 61 can be started to make the rotating rod 62 drive the turntable 63 to rotate, which in turn drives the clamped lower cylinder of the shielding tube to rotate, so as to correct the lower cylinder of the shielding tube to the corresponding insertion position with the upper cylinder of the shielding tube, which facilitates welding and improves the welding effect of the shielding tube. The combination of the above structures can improve the welding effect of the shielding tube.

Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
