Obviously, the drawings described below are only some embodiments of the present invention. For ordinary technicians in this field, other drawings can be obtained based on these drawings without paying creative work.

[0026] Figure 2 It is a structural schematic diagram of the present invention. DETAILED DESCRIPTION

[0027] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below.

[0028] See also Figure 2 The fixing device for the core diaphragm box and the diaphragm cover of the diaphragm gas meter provided by the present invention includes an external shell 300, a lifting mechanism 400, a workbench 500 and a diaphragm cover mounting platform 600.

[0029] The outer shell 300 is specifically a rectangular sealed cover. The lifting mechanism 400, the workbench 500 and the membrane cover mounting platform 600 are all located inside the outer shell 300, which is used to provide a sealed environment for the movement membrane box 100 and the membrane cover 200 during assembly.

[0030] When the movement membrane box 100 and the membrane cover 200 are fixed by vibration and friction, if there is dust or other substances between the movement membrane box 100 and the membrane cover 200, this will affect the quality. By working in the external shell 300, assembly in a dust-free environment can be ensured to improve the quality.

[0031] A material port 310 is provided on the external shell 300, and a movable door panel is provided on the material port 310. The material port 310 can be opened and sealed by moving the door panel. The staff can place the movement membrane box 100 and the membrane cover 200 on the workbench 500 and the membrane cover mounting table 600 respectively through the material port 310, and the assembled movement membrane box 100 can also be taken out through the material port 310, which neither affects the feeding and taking of materials nor ensures that the present application works in a sealed environment.

[0032] In addition, the door panel may be transparent, so that even after the door panel seals the material opening 310, the working conditions inside the external shell 300 can be observed in real time through the door panel, which is convenient for timely understanding.

[0033] The lifting mechanism 400 is disposed in the external shell 300 and is used to drive the workbench 500 to move up and down in the vertical direction. Specifically, it may include two symmetrical lifting cylinders, which are respectively located on both sides of the external shell 300.

[0034] The workbench 500 is movably disposed on the lifting mechanism 400, and is specifically fixed on two lifting cylinders. The lifting cylinders operate to enable the workbench 500 to move up and down in a vertical direction.

[0035] At least one movement membrane box placement groove 510, at least one limiting structure 520 and at least one vibration structure 530 are provided on the workbench 500. The movement membrane box 100 to be fixed can be detachably installed in the movement membrane box placement groove 510 and is limited by the limiting structure 520, while the vibration structure can drive the movement membrane box 100 to vibrate in the movement membrane box placement groove 510.

[0036] The movement membrane box seating groove 510 is specifically in the shape of a “[”. After the movement membrane box 100 is placed in the movement membrane box seating groove 510 , one side thereof is located in the movement membrane box seating groove 510 , while the other side is located outside the movement membrane box seating groove 510 .

[0037] The limiting structure 520 includes a limiting plate, and a slide groove is provided on the workbench 500. The limiting plate is movably set on the slide groove. The limiting plate is specifically in a "]" shape and matches the shape of the movement membrane box mounting groove 510. The limiting plate can contact the movement membrane box mounting groove 510 by moving on the slide groove to form a fully enclosed "mouth" shape. At this time, the other side of the movement membrane box 100 located outside the movement membrane box mounting groove 510 is just located inside the limiting plate, and the limiting plate can limit the axial movement of the movement membrane box 100 without affecting the vibration of the movement membrane box 100 in the movement membrane box mounting groove 510.

[0038] By setting the above-mentioned limiting structure 520, the installation and removal of the movement membrane box 100 are very convenient. When installing, it is only necessary to move the limiting structure 520 to contact with the movement membrane box 100. When taking it, it is only necessary to move the limiting structure 520 in the opposite direction.

[0039] In addition, by setting the above-mentioned limiting structure 520, the present application can also be suitable for movement membrane boxes 100 of different sizes, so there is no need to open a separate mold for each size of the movement membrane box 100, which saves costs.

[0040] The vibration structure 530 is used to drive the movement membrane box 100 to vibrate in the movement membrane box placement groove 510, and may specifically include a vibration motor. A vibration plate may be set in the movement membrane box placement groove 510, and the movement membrane box 100 is placed on the vibration plate. In this way, the vibration motor drives the vibration plate to vibrate, thereby driving the movement membrane box 100 to vibrate in the movement membrane box placement groove 510.

[0041] The membrane cover mounting platform 600 is used to mount the membrane cover 200 , so that the membrane cover 200 can be mounted in cooperation with the movement membrane box 100 on the workbench 500 .

[0042] The membrane cover mounting platform 600 specifically includes a horizontal platform 610, which is arranged at the top of the external shell 300. A plurality of mounting plates 620 are arranged on the lower surface of the horizontal platform 610. A membrane cover mounting groove 630 may be arranged on each mounting plate 620, and each membrane cover mounting groove 630 corresponds to a movement membrane box mounting groove 510. The membrane cover 200 may be installed in the movement membrane box mounting groove 510, so that when the movement membrane box 100 in the movement membrane box mounting groove 510 moves on the lifting mechanism 400 through the workbench 500, it can contact the membrane cover 200 in the membrane cover mounting groove 630, and drive the movement membrane box 100 to vibrate through the vibration structure 530 to achieve vibration friction fixation.

[0043] Due to the influence of gravity, when the membrane cover 200 is directly placed in the membrane cover seating groove 630, it will be affected by gravity and easily fall off. If a fixing method such as a snap is set in the membrane cover seating groove 630, this will affect the installation of the membrane cover 200 and the movement membrane box 100. The present application can set an adsorption structure in the membrane cover seating groove 630 to absorb the membrane cover 200 by gas adsorption. This can fix the membrane cover 200 without affecting the assembly of the membrane cover 200 and the movement membrane box 100.

[0044] The adsorption structure may specifically include a plurality of suction pipes and a plurality of suction heads. A plurality of suction ports are provided on the contact surface between the membrane cover mounting groove 630 and the membrane cover 200. A suction head is provided on each suction port. Each suction pipe is connected to a suction head. The air pump is respectively connected to each suction pipe. In this way, the air pump can suction through the suction head, thereby adsorbing the membrane cover 200 placed in the membrane cover mounting groove 630.

[0045] The adsorption structure used in the present application is not limited to the above-mentioned structure, and any other structure may be used as long as it can achieve adsorption of the membrane cover 200.

[0046] In addition, although the membrane cover 200 and the core membrane box 100 are dust-free assembled in the external housing 300, the membrane cover 200 and the core membrane box 100 may be contaminated with dust and other substances on the outside before entering the external housing 300, thereby affecting the quality. In addition to suction, the above-mentioned adsorption structure used in this application can also be used for blowing, such as:

[0047] First, install the core membrane box 100 into the core membrane box placement groove 510, then do not install the membrane cover 200 in the membrane cover placement groove 630, and then move the workbench 500 upward on the lifting mechanism 400 so that the core membrane box 100 is close to the membrane cover placement groove 630. At this time, the air pump works and blows air through the suction head to blow the core membrane box 100 in the core membrane box placement groove 510. After the blowing is completed, the workbench 500 moves downward on the lifting mechanism 400, and then the membrane cover 200 is installed. 0 is first flipped over so that the contact surface of the membrane cover 200 and the movement membrane box 100 contacts the membrane cover receiving groove 630, and then the air pump is controlled to blow air through the suction head to blow air to the membrane cover 200 in the membrane cover receiving groove 630. After the blowing is completed, the membrane cover 200 is flipped over again and placed in the membrane cover receiving groove 630, and then the air pump is controlled to exhaust air through the suction head to exhaust air to the membrane cover 200 in the membrane cover receiving groove 630 to achieve adsorption, and finally assembly is performed, which can further improve the assembly quality.

[0048] In order to improve operational efficiency, the present application may also include a controller, which is respectively connected to the lifting mechanism 510, the limiting structure 520, the vibration structure 530 and the movable door panel on the material port, so that the staff can perform remote engineering through the controller outside, which is very convenient.

[0049] In addition, in order to improve safety, an emergency switch can be provided outside the external shell 300, and the emergency switch is connected to the controller. When an emergency occurs, the staff can perform emergency braking through the emergency switch, thereby improving safety.

[0050] The following is the specific working process of this application:

[0051] The staff first controls the movable door panel to open through the controller, then installs the movement membrane box 100 into the corresponding movement membrane box placement groove 510, and controls the limiting mechanism 520 to work to limit the movement membrane box 100, and then installs the membrane cover 200 into the corresponding membrane cover placement groove 630, and controls the adsorption structure to work through the controller to adsorb the membrane cover 200;

[0052] Then, the controller controls the workbench 500 to move upward on the lifting mechanism 400 until the movement membrane box 100 in the movement membrane box placement groove 510 contacts the membrane cover 200 in the membrane cover placement groove 630 and stops moving. Then, the controller controls the vibration structure 530 to drive the movement membrane box 100 to vibrate to achieve vibration friction fixation. After fixation, the membrane cover 200 in the membrane cover placement groove 630 and the movement membrane box 100 will be fixed as one. Then, the controller controls the adsorption structure to stop working, and then the controller controls the workbench 500 to move downward on the lifting mechanism 400.

[0053] After moving to the corresponding position, the staff controls the movable door panel to open through the controller, and controls the limit mechanism 520 to work, separates from the movement membrane box 100, takes the movement membrane box 100 out of the movement membrane box placement groove 510, and then turns the movement membrane box 100 over and puts it back into the movement membrane box placement groove 510, so that the side without the membrane cover 200 is facing upward, and then installs the membrane cover 200 on the other side into the corresponding membrane cover placement groove 630, and controls the adsorption structure to work through the controller to adsorb the membrane cover 200;

[0054] Then, the controller controls the workbench 500 to move upward on the lifting mechanism 400 until the movement membrane box 100 in the movement membrane box placement groove 510 contacts the membrane cover 200 in the membrane cover placement groove 630 and stops moving. Then, the controller controls the vibration structure 530 to drive the movement membrane box 100 to vibrate to achieve vibration friction fixation. After fixation, the membrane cover 200 in the membrane cover placement groove 630 and the movement membrane box 100 will be fixed as one. Then, the controller controls the adsorption structure to stop working, and then the controller controls the workbench 500 to move downward on the lifting mechanism 400.

[0055] After moving to the corresponding position, the staff controls the movable door panel to open through the controller, and controls the limiting mechanism 520 to work, separates from the movement membrane box 100, and takes the movement membrane box 100 out of the movement membrane box placement groove 510. At this time, the membrane cover 200 is installed on both sides of the movement membrane box 100, and then the movement membrane box 100 is taken out from the external shell 300 through the material port.
