The bottom of the nipple-shaped water fountain is designed into a regular hexagonal prism shape, and the top of the screwing head 6-9 of the water fountain is designed into a hexagon socket shape. The nipple-shaped water dispenser and the water dispenser screwing head 6-9 can be matched with each other. When the drinking fountain is arranged on the screwing head 6-9 of the drinking fountain, the charging auxiliary cylinder 6-12 is pushed out to jack up the screwing head 6-9 of the drinking fountain, and the screwing head 6-9 of the drinking fountain is in soft contact with the bottom of the drinking fountain through the spring force. Meanwhile, the screwing motor 6-14 is arranged to drive the water fountain screwing head 6-9 to rotate slowly, so that the water fountain falls into the inner hexagonal blind hole of the water fountain screwing head 6-9. When the drinking bowl falls into the inner hexagonal blind hole of the screwing head 6-9 of the drinking bowl, the screwing motor 6-14 stops rotating. And each second clamping pneumatic clamping jaw 6-6 clamps the corresponding drinking water pipe, and the jacking cylinder jacks up and screws up the lifting plate 6-4 to drive the whole water fountain screwing head 6-9 to ascend, so that the water fountain is in soft contact with the drinking water hole in the drinking water pipe and is aligned with the center. Then, the screwing motor 6-14 is used for driving the water fountain screwing head 6-9 to rotate, and under the combined action of spring force and rotation, the external threads on the water fountain directly tap the drinking holes in the drinking water pipe into threaded holes, so that the threaded connection between the water fountain and the drinking water pipe is realized.

The working principle of the utility model is as follows:

the process of feeding the drinking water pipe comprises the following steps:

a worker puts a row of drinking water pipes on each transverse conveyor 3-1 of the drinking water pipe feeding device I; the feeding limiting plate group 2 enables the drinking water pipes to be arranged one by one and aligned with each other. The transverse conveyor 3-1 drives the drinking water pipes to move towards the material blocking assembly 3-2 and the positioning assembly 3-3. Pushing out the blocking contraposition cylinders 3-2-3 to enable the blocking limiting wheels 3-2-4 to block the drinking water pipes from being conveyed inwards continuously;

after one drinking water pipe is contacted with the blocking limiting wheel 3-2-4, the blocking jacking cylinder 3-2-1 is pushed out to clamp the drinking water pipe between the blocking jacking plate and the blocking clamping frame 3-2-2, so that other drinking water pipes except the drinking water pipe contacted with the blocking limiting wheel 3-2-4 are prevented from entering the positioning component 3-3; the material blocking and jacking cylinder 3-2-1 retracts after being pushed out, and a drinking water pipe is released to enter the positioning assembly 3-3.

After the water drinking pipes entering the positioning assembly 3-3 are limited, the material blocking assembly 3-2 releases the next water drinking pipe to enter the positioning assembly 3-3, so that a group of four water drinking pipes enter the positioning assembly 3-3 one by one to be limited. The blocking component 3-2 realizes the release of the drinking water pipes one by one through the sequence of 'pushing out of the blocking jacking cylinder 3-2-1 → retracting of the blocking jacking cylinder 3-2-1 → contacting of a drinking water pipe with the blocking limiting wheel 3-2-4 → pushing out of the blocking jacking cylinder 3-2-1 → retracting of the blocking jacking cylinder 3-2-1'. The first drinking water pipe entering the positioning component 3-3 is limited by the fixed limiting block 3-3-1, and the second, third and fourth drinking water pipes are limited by three feeding limiting wheels 3-3-3 which are sequentially far away from the fixed limiting block 3-3-1. After the material blocking assembly 3-2 releases the four drinking water pipes to enter the positioning assembly 3-3, the drinking water pipes are not released continuously until the four drinking water pipes entering the positioning assembly 3-3 completely leave the drinking water pipe feeding device I. In the conveying process of the first drinking water pipe, the three limiting cylinders 3-3-2 are retracted; in the second, third and fourth drinking water pipe conveying process, the corresponding three limiting cylinders 3-3-2 are sequentially pushed out for limiting.

And finally, the aligning cylinder is pushed out, so that the drinking water pipes on the four production stations are all abutted against the tail end limiting plate 2-2, and the positioning accuracy of the drinking water pipes is ensured. A grabbing cylinder 3-4-1 in the grabbing component 3-4 drives each feeding pneumatic clamping jaw 3-4-3 to move downwards to grab the corresponding drinking water pipe; the bottom edge of the picked drinking water pipe is contacted with the roller 3-4-5 on the feeding pneumatic clamping jaw 3-4-3.

The feeding process of the water fountain comprises the following steps:

the staff places the stacked material tray on the material tray lifting frames 8-3 of the two material tray lifting mechanisms 8. The distance adjusting cylinder 11-6 in the water fountain feeding device III is pushed out, and the two water fountains grab the pneumatic clamping jaws 11-7 to clamp the water fountains on the material tray.

And the distance adjusting air cylinders 11-6 in the water fountain feeding device III retract, so that the center distance between the two water fountains grabbing the water fountains on the pneumatic clamping jaws 11-7 is increased to the center distance between the water drinking pipes on the two adjacent production stations. The first grabbing electric sliding table 11-1, the second grabbing electric sliding table 11-2, the grabbing pneumatic sliding table 11-3 and the rotary table of the rotary cylinder 11-4 move synchronously, and two water fountains clamped on the two water fountain feeding devices III respectively move to the positions right below the ith-1 th water fountain mounting position of the four water drinking pipes.

The second electric sliding table 6-2 in the two tightening units drives the tightening frame 6-3 to move horizontally, so that the four water fountain screwing heads 6-9 move to positions right below the four water fountains respectively. The charging auxiliary cylinder 6-12 is pushed out to jack up the water fountain screwing heads 6-9, so that the four water fountain screwing heads 6-9 are in soft contact with the four water fountains under the action of the springs 6-13; the four water fountain screwing heads 6-9 are driven by the corresponding upper screwing motors 6-14 to rotate until the inner hexagonal blind holes at the tops of the four water fountain screwing heads 6-9 correspond to the hexagonal prism side walls of the water fountains, and the four water fountains respectively fall into the inner hexagonal blind holes of the four water fountain screwing heads 6-9. Each drinking device grabs the pneumatic clamping jaws 11-7 to be loosened and returns to the upper part of the corresponding material tray.

The process of punching holes on the drinking water pipe and installing drinking water devices is as follows:

a first electric sliding table 4-2 in the drinking water pipe pulling mechanism 4 drives four pulling pneumatic clamping jaws 4-5 to respectively move to the end parts of four drinking water pipes which are positioned. Four dragging pneumatic clamping jaws 4-5 clamp four drinking water pipes respectively. The drinking water pipe drawing mechanism 4 draws the four drinking water pipes into the drilling and screwing device II, and the drilling mechanism 7 drills drinking water holes on n drinking water device mounting positions on the drinking water pipes. The tightening mechanism 6 is used for installing drinking water devices for drinking water holes on the drinking water pipes.

The drilling process comprises the following steps: the drinking water pipe pulling mechanism 4 pulls the positions to be punched on the four drinking water pipes to be above the four drill bits 7-4. Four first clamping pneumatic clamping jaw groups in the drilling mechanism 7 respectively clamp four drinking water pipes, and four drill bits 7-4 respectively drill drinking water holes on the four drinking water pipes under the driving of a drilling motor 7-3 and a drilling upper jacking cylinder 7-5.

The process of installing the drinking fountain comprises the following steps:

four water fountain screwing heads 6-9 provided with water fountains move to positions right below the drinking holes on the four water fountains. The upper screwing motor 6-14 rotates to screw the upper top cylinder 6-5 to push out, so that the four water fountains are screwed on the drinking holes on the four drinking water pipes respectively.

The process of blanking the drinking water pipe is as follows:

the drinking water pipe which completes the installation of the drinking water device enters the blanking mechanism 12 under the pushing of the subsequent drinking water pipe; after four drinking water pipes enter a second slide way 12-5 of the blanking mechanism 12, the blanking lifting cylinders 12-1 in the five blanking mechanisms 12 retract, so that the four drinking water pipes are transferred to the blanking support rods 12-3; the outer pushing plate 13-2 in each pushing mechanism 13 pushes the corresponding two drinking water pipes from inside to outside, so that every two drinking water pipes are pushed to two sides of the blanking rack 1-4 respectively in a group; then, each second slideway 12-5 and each outer push plate 13-2 are reset.
