Description

Technical Field

[0001] The present invention relates to the technical field of electromagnetic flowmeter assembly, and more specifically, to a modular assembly device for electromagnetic flowmeter sensors. Background Art

[0002] The electromagnetic flowmeter is generally composed of two parts in structure: electromagnetic flow sensor and electromagnetic flow converter. The electromagnetic flow sensor is mainly composed of measuring tube, excitation system, electrode, lining and interference adjustment mechanism and other shell parts. The function of the lining is to prevent the induced signal voltage from being short-circuited by the metal tube. In the prior art, during the assembly of the lining of the electromagnetic flow sensor, since the lining is usually made of soft rubber, it is easy for the lining to be uneven and needs to be leveled. When leveling it, it is difficult to level the entire lining, which reduces the assembly effect. According to the patent document with publication number CN221415662U, the starting motor in the device drives the pressure roller to rotate so as to level the entire lining to prevent the lining from being uneven. However, in the above patent document, when assembling the lining and the pipeline, the outer wall of the lining and the inner wall of the pipeline are not cleaned and pre-treated synchronously, and the impurities present will cause the lining and the pipeline to be unable to fit closely, resulting in a decrease in the sealing performance of the electromagnetic flowmeter sensor when in use. At the same time, it is impossible to ensure the alignment of the top of the lining and the top of the pipeline synchronously during the leveling process of the lining, so as to jointly improve the assembly quality of the lining and the pipeline.

[0030] When the lining is made of rubber: control the air pump 81 to work, and open the control valve three and the control valve two 813 at the same time, and continuously fill the inside of the annular airbag 87 with air, so that the airbag is quickly filled, and the leveling of the soft rubber lining is completed, so that the soft rubber and the inner wall of the pipeline are completely fitted; the gas enters the pusher 814 through the leveling pipe 811, and the pusher 814 pushes the connecting plate 815 downward, so that the leveling plate 817 pushes the soft rubber downward synchronously, ensuring that the top of the soft rubber is aligned with the top of the pipeline, and the two interact with each other to jointly improve the assembly quality of the soft rubber lining and the pipeline; When the lining is made of non-rubber material: control the air pump 81 to work, and open the control valve 2 813 at the same time, so that the gas enters the pusher 814 through the leveling pipe 811, and the pusher 814 pushes the connecting plate 815 downward, so that the top of the lining is aligned with the top of the pipeline, thereby improving the assembly quality of the lining and the pipeline; Liners and pipes made of various materials can be assembled to improve the adaptability of the device during use; Embodiment 2: Figure 1 , 12 As shown, a modular assembly device for electromagnetic flowmeter sensors proposed in this embodiment is improved on the basis of embodiment 1, two electric push rods 9 are symmetrically arranged above the processing table 1, the two electric push rods 9 are located on both sides of the conveyor 2 4, and a fixed plate 10 is arranged at the output end of the electric push rod 9, and the two fixed plates 10 are arranged opposite to each other; The electric push rod 9 controls the two fixing plates 10 to move closer to each other to fix the pipe so that it is in the position to be processed; like Figure 4 , 8-9, the clamping member includes a clamping plate 86 fixedly connected to the output end of the cylinder 6, a bidirectional threaded screw 818 is rotatably arranged inside the clamping plate 86, one end of the bidirectional threaded screw 818 extends to the outside of the clamping plate 86 and is fixedly provided with a motor 1, and the outer walls of both sides of the bidirectional threaded screw 818 are connected to a moving plate 84, and the moving plate 84 is slidably matched with the inner wall of the clamping plate 86; By controlling motor 1, the bidirectional threaded screw 818 is rotated, thereby controlling the two clamping plates 86 to move closer to or away from each other, thereby achieving assembly of the liner and the pipeline.

[0031] Working principle: When the present invention is in use, first, the combined mechanism 8 is controlled by the moving part 7 to move to one side to the top of the lining. At this time, the conveyor 2 stops working, and the cylinder 6 pushes downward to move the two arc plates 85 to the inside of the lining. Then, the two arc plates 85 are moved away from each other by the clamping part to complete the fixation of the lining. Subsequently, the air pump 81 and the control valve 892 are turned on to blow the gas along the two outer flushing pipes 894. Under the premise of limiting the position of the lining, the outside of the lining is cleaned. After the cleaning is completed, the control valve 892 is closed; then, the cylinder 6 is reset, and the lining is moved to the top of the pipeline to be processed by the moving part 7 again; in this process, the electric push rod 9 controls the two fixed plates 10 to move closer to each other to fix and limit the pipeline, so that it is in the position to be processed, and the conveyor 4 stops running; the cylinder 6 is controlled to move downward again to move the lining to the inside of the pipeline; When the lining is made of rubber: control the air pump 81 to work, and open the control valve three at the same time, continuously fill the inside of the annular airbag 87 with air, so that the airbag is quickly filled, and the leveling of the soft rubber lining is completed, so that the soft rubber and the inner wall of the pipeline are completely fitted. At the same time, open the control valve two 813, so that the gas enters the pusher 814 through the leveling pipe 811, and the pusher 814 pushes the connecting plate 815 downward, so that the leveling plate 817 pushes the soft rubber downward synchronously, ensuring that the top of the soft rubber is aligned with the top of the pipeline. The two interact with each other to jointly improve the assembly quality of the soft rubber lining and the pipeline, and after the assembly is completed, close the control valve three and the control valve two 813 in time; When the lining is made of non-rubber material: control the air pump 81 to work, and open the control valve 2 813 at the same time, so that the gas enters the pusher 814 through the leveling pipe 811, and the pusher 814 pushes the connecting plate 815 downward, so that the top of the lining is aligned with the top of the pipeline, thereby improving the assembly quality of the lining and the pipeline; the present invention can assemble liners and pipelines of various materials, thereby improving the adaptability of the device when used; Subsequently, the control valve 4 on the impact pipe is opened, so that the annular airbag 87 is at the filling degree of the material discharge, and the control valve 4 is closed again. At this time, the annular airbag 87 is still filled, and then the two arc plates 85 are brought close to each other through the clamping member, and the combination mechanism 8 is taken out of the pipeline, and the cylinder 6 is reset. Then, when the next pipeline moves to the position to be processed, the control valve 4 is opened again, so that the gas inside the control valve 4 rushes out toward the inside of the pipeline to be processed, and the pretreatment of the pipeline is completed, and the outer ring of the liner is cleaned to avoid impurities on the fitting surface between the liner and the pipeline when they are assembled, resulting in the inability of the two to fit closely and the reduction of sealing performance; Subsequently, the air relief valve and the control valve 2 813 on the air relief pipe 812 are opened to reset the pusher 814; Follow the above steps to complete the installation of the lining and pipe.
