[0002] A water meter is an instrument for measuring water flow, most of which measure the cumulative flow of water. It is generally divided into two categories: volumetric water meters and velocity water meters. When selecting the specifications of a water meter, you should first estimate the size and range of the flow rate normally used, and then choose the water meter with the specification that is closest to the commonly used flow rate as the first choice.

[0003] During the processing of the water meter, it is necessary to drill holes in the inner cavity of the water meter shell to install internal components. During the drilling process, the water meter shell needs to be positioned first, and then the drilling machine is controlled to insert into the inner cavity of the water meter shell to drill holes. A certain amount of debris will be generated during the drilling process. These debris will fall into the inner cavity of the water meter shell and remain on the inner wall of the drilled hole. In order to prevent these debris from affecting the subsequent water meter processing and assembly, the debris in the inner cavity of the water meter shell needs to be cleaned out. In the prior art, generally, staff manually hold cleaning tools to clean the debris in the inner cavity of the water meter shell, and the manual cleaning process is time-consuming and laborious, especially for the inner cavity of some larger water meter shells.

[0025] Specifically, by vibrating the outer shell of the water meter, the waste debris attached to the inner cavity of the outer shell of the water meter is more fully and thoroughly shaken off and discharged from the inner cavity of the outer shell of the water meter, thereby improving the discharge effect of the drilling waste debris.

[0031] Specifically, the two fourth motors are started to drive the two second rotating rods to rotate clockwise or counterclockwise, and the two second rotating rods can stably drive the brush 71 to swing back and forth to the right or left.

[0032] See also Figure 5-Figure 9 The second rotating assembly 73 includes a third rotating rod rotatably connected to the top of the lifting plate 62, the top of the third rotating rod is fixedly connected to the rotating plate 731, the fixed box 721 is fixedly connected to the top of the rotating plate 731, the bottom end of the third rotating rod passes through the lifting plate 62 and is fixedly connected to a disc 732, and the bottom of the disc 732 is fixedly connected to a plurality of fixing bars 733 in a ring-shaped manner at equal angles. The second rotating assembly 73 also includes a transmission mechanism 734 and a driving mechanism 735 connected to the lifting plate 62. The driving mechanism 735 intermittently drives the plurality of fixing bars 733 to rotate counterclockwise by the same angle in sequence through the transmission mechanism 734.

[0033] See also Figure 5-Figure 9 The transmission mechanism 734 includes two sliding sleeves 7341 symmetrically fixedly connected to the bottom of the lifting plate 62 with the axis of the third rotating rod as the reference, two guide rods 7342 are slidably connected to the two sliding sleeves 7341, two fixed blocks 7343 are symmetrically fixedly connected to the ends of the two guide rods 7342 close to the disc 732, two ratchet teeth 7344 are symmetrically fixedly connected to the tops of the two fixed blocks 7343, and both ratchet teeth 7344 can contact the side of the fixed bar 733, and two pull plates 7345 are symmetrically fixedly connected to the ends of the two guide rods 7342 away from the disc 732.

[0034] Specifically, the start-up driving mechanism 735 intermittently pushes the top ends of the two driving rods 7347 that are close to each other to rotate downward, and the two driving rods 7347 drive the bottom ends of the two levers 7346 to swing in directions away from each other, and the bottom ends of the two levers 7346 push the two pull plates 7345 to move in directions away from each other, and the two pull plates 7345 drive the two ratchet teeth 7344 to move in directions away from each other through the two guide rods 7342 and the two fixing blocks 7343, and the two ratchet teeth 7344 drive the fixing bars 733 to move in directions away from each other. The disc 732 rotates counterclockwise by a certain angle, and the disc 732 drives the brush 71 to rotate counterclockwise by a certain angle through the third rotating rod and the rotating plate 731. When the driving mechanism 735 releases the driving rod 7347, the two ratchet teeth 7344 move away from each other under the elastic force of the second elastic member. Due to the structure of the ratchet teeth 7344, the ratchet teeth 7344 rotate at this time and cannot push the fixed bar 733 to swing.

[0035] See also Figure 5-Figure 9 The driving mechanism 735 includes two pressure rods 7351 which are symmetrically and movably plugged into the top of the lifting plate 62 with the axis of the third rotating rod as the reference.

The bottom ends of the two pressure rods 7351 pass through the lifting plate 62 and are respectively tightly pressed against the top ends of the two driving rods 7347.

[0036] Specifically, when the first cylinder 3 is started and the water meter outer shell with the opening facing downward is driven to hit the two top plates 63 through the two clamping plates 41, the top plates 63 will cooperate with the cross plate 7352 to overcome the elastic force of the fifth elastic member 7353 and the sixth elastic member 631 to push the two pressure rods 7351 downward, and the bottom ends of the two pressure rods 7351 will respectively push the top ends of the two driving rods 7347 close to each other to rotate downward to drive the brush 71 to rotate counterclockwise, and when the first cylinder 3 drives the water meter outer shell to move upward, the pressure rod 7351 will reset upward, and at this time, under the elastic force of the fourth torsion spring, the driving rod 7347 will reset and drive the ratchet 7344 to reset, and the ratchet 7344 will not push the fixed bar 733 to rotate when it resets, so that the reciprocating cycle can stably and intermittently drive the brush 71 to rotate counterclockwise at equal angles, thereby improving the reliability of the oblique punching device; Two fourth cylinders 8 are symmetrically fixedly connected to the top of the base 1, and two support plates 9 are symmetrically fixedly connected to the output ends of the two fourth cylinders 8. The two support plates 9 can be moved to the top of the chip collecting groove 11 and cover the chip collecting groove 11. When the two fourth cylinders 8 are started to extend and push the two support plates 9 to move to the top of the chip collecting groove 11, the outer shell of the water meter during the drilling process can be supported to ensure that the drilling process is carried out stably and reliably. When it is necessary to clean and discharge the waste chips in the inner cavity of the outer shell of the water meter, the two fourth cylinders 8 are started to contract and pull the two support plates 9 backwards until the support plates 9 are located on the rear side of the chip collecting groove 11, thereby ensuring that the cleaning operation of the waste chips in the inner cavity of the outer shell of the water meter can be carried out smoothly.

[0037] Working principle: the staff places the opening of the water meter outer shell to be drilled upward and on the top of the two support plates 9, then starts the two pairs of second cylinders 43 to push the two clamping plates 41 in the direction of approaching each other through the two second fixing plates 44 to clamp the water meter outer shell, cooperates with the two second motors to drive the two clamping plates 41 to rotate forward or backward to drive the water meter outer shell to rotate forward or backward, starts the two first motors 53 to rotate synchronously clockwise or counterclockwise, so that the first motor 53 can stably drive the water meter outer shell to swing to the right or left through the first rotating rod, the first swing plate 52, the second motor and the two clamping plates 41, and at the same time, the two pairs of second cylinders 43 can be started to drive the two clamping plates 41 to move left and right respectively, and then cooperate with the lifting mechanism 22 to drive the drill rod 21 to move up and down and the seventh motor to rotate forward or reverse to drive the drill rod 21 to swing back and forth, so that the drill rod 21 can drill an inclined hole with any inclination angle on the inner wall of the inner cavity of the water meter outer shell, thereby improving the drilling flexibility and reliability of the inclined drilling device.

[0038] After the drilling is completed, the two second motors are started to drive the two clamping plates 41 to rotate forward or backward to drive the outer shell of the water meter to rotate forward or backward 180 degrees. At this time, the opening of the outer shell of the water meter can be downward, so that the waste chips dropped into the inner cavity of the outer shell of the water meter during the drilling process can be quickly dumped out and fall into the chip collecting groove 11, realizing automatic discharge of waste chips; Then, the two fourth air cylinders 8 are started to retract and pull the two support plates 9 backward until the support plates 9 are located at the rear side of the chip collecting groove 11, so as to ensure that the cleaning operation of the waste chips in the inner cavity of the water meter housing can be carried out smoothly; Then start the third cylinder 61 to push the lifting plate 62 and the two top plates 63 upward to the highest point, and then start the first cylinder 3 to drive the water meter outer shell with the opening facing downward to move back and forth up and down and collide with the two top plates 63, so that the water meter outer shell can be reliably vibrated to shake off and discharge the waste debris remaining in the inner cavity of the water meter outer shell.

[0039] When the outer shell of the water meter intermittently collides with the two top plates 63, the top plates 63 will cooperate with the cross plate 7352 to overcome the elastic force of the fifth elastic member 7353 and the sixth elastic member 631 to push the two pressure rods 7351 downward, and the bottom ends of the two pressure rods 7351 will respectively push the top ends of the two driving rods 7347 close to each other to rotate downward to drive the brush 71 to rotate counterclockwise. When the first cylinder 3 drives the outer shell of the water meter to move upward, the pressure rod 7351 will reset upward. At this time, under the elastic force of the fourth torsion spring, the driving rod 7347 will reset and drive the ratchet 7344 to reset, and the ratchet 7344 will not push the fixed bar 733 to rotate when it resets. Such a reciprocating cycle can stably and intermittently drive the brush 71 to rotate counterclockwise at equal angles to brush and clean the waste debris on the inner wall of the inner cavity of the outer shell of the water meter, thereby improving the reliability of the oblique punching device.

[0040] At the same time, the two fourth motors are started to drive the two second rotating rods to rotate clockwise or counterclockwise. The two second rotating rods can stably drive the brush 71 to swing back and forth to the right or left to cooperate with the second rotating component 73 to more thoroughly and fully brush and clean the waste on the inner wall of the inner cavity of the water meter shell.
