Description
Technical Field
The invention relates to a production technology of a thin film type gas meter, in particular to a flag rocking mechanism assembling device of the thin film type gas meter.
Background
In the prior art, a cassette body (also called a diaphragm capsule) of a core of a thin film type gas meter is provided with a left gas measurement chamber and a right gas measurement chamber which are the same, each gas measurement chamber is divided into two small measurement chambers with the same volume by a soft diaphragm, when flowing gas enters the four small measurement chambers in sequence, the diaphragms are pushed to open or close, each small measurement chamber is controlled to be sequentially inflated and exhausted, and then a flag rocking mechanism is driven to drive a double-crank rocker mechanism to rotate, so that a valve cover rotates, and the gas meter continuously and circularly moves. Meanwhile, an eccentric gear arranged on a connecting rod mechanism of the gas meter core drives a mechanical one-way counter to count, and finally gas metering is realized. Generally, there are two sets of flag-shaking mechanisms in a gas meter movement, and there is one set of left and right gas chambers of a movement box body, which are symmetrically arranged inside the movement box body. The flag-rocking mechanism is a key mechanism for converting the swinging motion of the diaphragm into the swinging motion of the rocker arm, and comprises a flag pole, a rotating shaft and the rocker arm. The flagpole (named after the flag in shape) is arranged in the core box body, the upper part of the flagpole is embedded in the chute of the diaphragm of the small metering chamber and can slide in the chute of the diaphragm, and the bottom through hole of the flagpole is fixedly connected with one end of the rotating shaft; the rotating shaft penetrates through a through hole at the bottom of the core box body and extends out of the core box body; the through hole at the bottom of the rocker arm is fixedly connected with the end head of the rotating shaft extending out of the machine core box (see figure 1). When the flowing gas pushes the diaphragm to open or close, the upper part of the flag pole slides along with the diaphragm sliding groove, so that the flag pole swings relative to the center of the rotating shaft, namely the flag pole drives the rotating shaft to rotate in a reciprocating manner, and the rocker arm is driven to swing.
At present, a flag pole and a rocker arm in a gas meter movement are fixedly connected with a rotating shaft in an interference fit press-fitting mode (see attached figure 2), the rotating shaft penetrating through a through hole in the bottom of a movement box body and the flag pole placed in the movement are pressed and mounted together by one press-fitting device, and the rocker arm is pressed and mounted on the rotating shaft by the other set of device. Because the two sets of equipment and the secondary press-fitting are adopted, secondary operation is needed, and the press-fitting efficiency is lower. In addition, the adoption of two sets of equipment and secondary press fitting can not ensure that the included angle alpha between the radial central line of the flagpole and the radial central line of the rocker arm meets the design requirement. The reason for this is that different batches of fittings may have different sizes and shapes (including the movement, flag pole, pivot shaft and rocker arm) and this difference may cause the error of the included angle α to exceed the design specification during press fitting. The radial center line of the flagpole refers to the center line of the axial thickness of the flagpole passing through the center of the through hole at the bottom of the flagpole, and the radial center line of the rocker arm refers to the center line of the axial thickness of the rocker arm passing through the center of the through hole at the bottom of the rocker arm (see the attached figure 3).

During specific adjustment, the stroke I is adjusted after the stroke II is adjusted; namely, the axial position of the rocker arm pressed on the rotating shaft is adjusted, and then the axial position of the flag pole pressed on the rotating shaft is adjusted.
As previously described, stroke ii corresponds to the operation of pressing the rocker arm into the spindle. The adjusting mechanism for the end position of the axial movement of the stroke II comprises a connecting rod 6-11, an adjusting washer 6-12 and a fixing bolt; one end of the connecting rod 6-11 is provided with an internal thread matched with the double-stroke cylinder piston rod thread section 6-5, and the other end of the connecting rod is provided with an internal thread matched with the fixing bolt; the inner hole of the adjusting washer 6-12 is matched with the outer diameter of the fixing bolt; during installation, one end of the connecting rod 6-11 is screwed on the threaded section 6-5 of the piston rod of the double-stroke cylinder, the fixing bolt is reversely penetrated through the through hole at the bottom of the sliding table, and after the adjusting washer 6-12 is sleeved, the fixing bolt is rotated into the other end of the connecting rod 6-11, so that the sliding table is fixedly connected with the piston of the double-stroke cylinder (see attached figure 6). Obviously, by increasing or decreasing the thickness of the adjusting washers 6-12, the length of the connection between the ramp and the piston rod can be varied. Under the condition that the distance of the axial movement of the stroke II is not changed, the end position of the axial movement of the stroke II can be changed by changing the connection length of the sliding table and the piston rod. And stroke ii corresponds to an operation of pressing the rocker arm into the rotary shaft, and the change of the axial movement termination position of stroke ii, that is, the change of the axial position at which the rocker arm is press-fitted onto the rotary shaft.
And the stroke i corresponds to an operation of pressing the rotation shaft into the flag pole. The adjusting mechanism for the axial movement termination position of the stroke I comprises a nut sleeve 6-7, an adjusting ring 6-8, a screw sleeve 6-9 and a fastening nut 6-10; the internal thread of the nut sleeve 6-7 is matched with the external thread of the screw rod sleeve 6-8, and the inner hole of the inner step at the end of the nut sleeve is matched with the diameter of the double-stroke cylinder piston rod 6-5; the inner diameter of the adjusting ring 6-9 is matched with the diameter of the external thread of the screw sleeve 6-8, and the outer diameter is matched with the outer diameter of the nut sleeve 6-7; the diameter of the inner hole of the screw rod sleeve 6-8 is matched with that of a piston rod 6-5 of the double-stroke cylinder, and the diameter of the outer step of the end head of the screw rod sleeve is matched with the outer diameter of the nut sleeve 6-7; the fastening nuts 6-20 are matched with the double-stroke cylinder piston rod thread sections 6-6; when the double-stroke air cylinder is installed, the nut sleeve 6-7 is sleeved on the double-stroke air cylinder piston rod 6-5, the adjusting ring 6-10 sleeved on the screw sleeve 6-8 is screwed in the nut sleeve 6-7, and the fastening nut 6-10 is rotated on the threaded section 6-5 of the double-stroke air cylinder piston rod, so that the nut sleeve 6-7, the adjusting ring 6-10 and the screw sleeve 6-8 are fixed on the double-stroke air cylinder piston rod 6-5 (see the attached figure 6). Obviously, the distance between the front end surface of the nut sleeve 6-7 and the double-stroke cylinder end cover can be changed by increasing or decreasing the thickness of the adjusting ring 6-8. The piston rod of the double-stroke cylinder pulls the nut sleeve assembly to move axially, and when the front end face of the nut sleeve is in contact with the end cover of the double-stroke cylinder, the axial movement of the piston rod of the double-stroke cylinder stops. Therefore, the axial moving distance of the piston rod of the double-stroke cylinder can be changed by changing the distance between the front end surface of the nut sleeve 6-7 and the end cover of the double-stroke cylinder, namely, the end position of the axial movement of the stroke I is changed. Because the sliding table is fixedly connected with the piston rod of the double-stroke air cylinder through the connecting rods 6-11, and the stroke I corresponds to the operation of pressing the rotating shaft into the flagpole, the change of the axial movement termination position of the stroke I means the change of the termination position of the pressing of the rotating shaft into the flagpole, namely the change of the axial position of the pressing of the flagpole on the rotating shaft.
