[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0034] Reference Figure 1-6This utility model provides an embodiment of a container shell roundness measuring device with rapid positioning function, including an adjusting device 1. The adjusting device 1 includes a base, a vertical rod, a first clamp, and a horizontal rod. The first clamp drives the horizontal rod to move up and down along the vertical rod to adjust the measuring position of the dial indicator 2. The dial indicator 2 is fixedly installed on the right side of the adjusting device 1. A rotating device 3 is provided on the right side of the adjusting device 1. The rotating device 3 includes a drive motor and a placement platform. Starting the drive motor drives the pressure vessel shell fixed on the top to rotate through the placement platform. A backing plate 4 is fixedly connected to the rear side of the top of the rotating device 3. A reinforcing plate 24 is fixedly connected to the rear side of the backing plate 4. By setting the reinforcing plate 24, the connection between the backing plate 4 and the rotating device 3 is prevented from breaking during the process of squeezing and fixing the pressure vessel shell. The bottom of the reinforcing plate 24 is fixedly connected to the top of the rotating device 3. An electric push rod 5 is fixedly installed on the front side of the top of the rotating device 3. A push plate 6 is fixedly connected to the output end of the electric push rod 5. The top of the push plate 6 is provided with a groove 7. Connecting blocks 8 are slidably connected to both sides inside the groove 7. A reset spring 21 is fixedly connected to the outside of the connecting block 8. The reset spring 21 pushes the connecting block 8 to reset, making it convenient for workers to use it next time. The side of the reset spring 21 away from the connecting block 8 is fixedly connected to the inner wall of the groove 7. Positioning blocks 9 are fixedly connected to both sides of the top of the push plate 6. The interior of the positioning blocks 9 and the connecting blocks 8 are movably connected to the first connecting plate 10 through a shaft. The side of the first connecting plate 10 away from the positioning blocks 9 is movably connected to the first extrusion plate 11 through a shaft. The top of the connecting block 8 is movably connected to the second connecting plate 12 through a shaft. A pressure sensor 22 is fixedly installed on the rear side of the second extrusion plate 13. The pressure sensor 22 controls the electric push rod 5 to stop, preventing excessive extrusion of the pressure vessel shell and causing deformation. The pressure sensor 22 is electrically connected to the electric push rod 5. The side of the second connecting plate 12 away from the connecting block 8 is movably connected to the second extrusion plate 13 through a shaft.

[0035] Reference Figure 1-3 The adjusting device 1 is equipped with an adaptation component, which includes a fixing block 14. The fixing block 14 is slidably connected inside the adjusting device 1. A shrinkage spring 15 is fixedly connected to the left side of the fixing block 14. The left side of the shrinkage spring 15 is fixedly connected to the inner wall of the adjusting device 1. The left side of the dial indicator 2 is fixed to the right side of the fixing block 14. When measuring the surface of the pressure vessel shell, when encountering a surface protrusion, the pressure vessel shell pushes the dial indicator 2 to move the fixing block 14 to the left and squeezes the shrinkage spring 15 to cause elastic contraction, thereby achieving the effect of measuring the pressure vessel shell with an uneven surface.

[0036] Reference Figure 3-5The first connecting plate 10 is provided with a limiting component inside. The limiting component includes a limiting rod 16, which is fixedly connected to both sides of the inner wall of the first extrusion plate 11. A limiting plate 17 is movably connected to the surface of the limiting rod 16. Rubber pads 23 are fixedly connected to the surfaces of the first extrusion plate 11, the second extrusion plate 12, and the limiting plate 17. The rubber pads 23 are provided to prevent the first connecting plate 10, the second connecting plate 12, and the limiting plate 17 from excessively extruding the pressure vessel shell and causing it to deform. Torsion springs 18 are fixedly connected to the top and bottom of the limiting plate 17. The side of the torsion spring 18 away from the limiting plate 17 is fixedly connected to the inner wall of the first extrusion plate 11. When the first extrusion plate 11 extrudes and fixes the pressure vessel shell, the limiting plate 17 rotates around the limiting rod 16 and extrudes the torsion spring 18, causing the torsion spring 18 to elastically compress. After the torsion spring 18 elastically extends, it pushes the limiting plate 17 to further fix the pressure vessel shell.

[0037] Reference Figure 1-3 The top of the rotating device 3 is provided with a positioning component, which includes a limiting block 19. The limiting block 19 is fixedly connected to both sides of the top of the rotating device 3. The limiting block 19 is slidably connected to a limiting slider 20. The rear side of the limiting slider 20 is fixedly connected to the front side of the push plate 6. Through the cooperation of the limiting block 19 and the limiting slider 20, the push plate 6 can be limited to prevent the push plate 6 from deviating during movement.

[0038] Working principle: When measuring the roundness of a pressure vessel shell, the electric push rod 5 is first activated, which drives the first extrusion plate 11 and the second extrusion plate 13 to move backward through the push plate 6. When one side of the pressure vessel shell contacts the rubber pad 23 and the other side contacts the abutment plate 4, the pressure vessel shell pushes the second extrusion plate 13 to move forward, which in turn drives the connecting block 8 to move to both sides, squeezing and compressing the reset spring 21. After the spring 21 is elastically compressed, the first connecting plate 10 is pushed by the connecting block 8, which drives the first extrusion plate 11 to move backward while rotating around the shaft. It cooperates with the abutment plate 4 to squeeze and fix the pressure vessel shell, thereby achieving the effect of quickly fixing the irregularly shaped pressure vessel shell. When measuring the roundness of a pressure vessel shell with an uneven surface, the pressure vessel shell pushes the dial indicator 2 to move the fixing block 14 to the left and squeezes the shrinking spring 15 to shrink elastically, thereby achieving the effect of measuring the pressure vessel shell with an uneven surface.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
