[0040] The utility model realizes the positioning of the motor housing through the positioning support unit 3, preliminarily fixes the motor housing at a predetermined position, and then the pressing unit 6 works to further fix the motor housing to prevent the motor housing from being offset during the process of pressing the water nozzle. After completing the fixing of the motor housing, the first nozzle pressing unit 4 and the cancellation unit 5 work simultaneously, the first nozzle pressing unit 4 presses the water nozzle into the first interface of the motor housing through the output end, and on the other side of the motor housing, the output end of the cancellation unit 5 extends out to press against the outer wall of the motor housing, which serves the purpose of offsetting part of the pressure of the first nozzle pressing unit 4, and preventing the motor housing from being deformed due to uneven force during the pressing process.
[0041] Preferably, the positioning support unit 3 includes a positioning seat 31, a limit block 32, a base 33 and a three-jaw internal support chuck 34; the positioning seat 31 is arranged on the processing table 2, and a plurality of positioning seats 31 are arranged, and the upper end of the positioning seat 31 is opposite to the hole groove at the lower end of the motor shell to be processed; the limit block 32 is arranged on the side of the positioning seat 31, and the limit block 32 is opposite to the arc groove of the lower end protrusion of the motor shell to be processed; the base 33 is arranged in the middle of the plurality of positioning seats 31, and the three-jaw internal support chuck 34 is arranged on the positioning seat 31.
[0042] The base 33 is provided with an annular positioning groove 331 , which is adapted to the inner edge contour of the lower end of the motor housing to be processed; the upper end of the three-jaw inner support chuck 34 is provided with a protective baffle.
[0043] The annular positioning slot 331 is adapted to the boss profile of the inner edge of the lower end of the motor housing. During the initial positioning, the lower end boss of the motor housing is just engaged with the annular positioning slot 331, and at the same time, the positioning seat 31 is aligned with the hole slot at the lower end of the motor housing, and the upper end of the positioning seat 31 is inserted into the corresponding hole slot to achieve further positioning. The limit block 32 is opposite to the arc groove of the lower end convex block of the motor housing, and can play a role in limiting and fixing the lower end convex block of the motor housing. When the first nozzle unit 4 is working, the limit block 32 can prevent the motor housing from rotating. At the same time, the three-claw inner support chuck 34 is opened, and the three claws are against the inner wall of the motor housing. One of the claws is located on the inner side of the first water nozzle, providing a part of the offsetting force for installing the water nozzle. The three-claw inner support chuck 34 is used to fix the motor housing to prevent the motor housing from tipping over or deforming when installing the water nozzle.
[0044] Specifically, the first nozzle pressing unit 4 includes a first mounting seat 41, a first hydraulic cylinder 42, a first sleeve 43 and a first fixing sleeve 44; the first mounting seat 41 is arranged on the processing table 2, the first hydraulic cylinder 42 is arranged on the first mounting seat 41, one end of the first sleeve 43 is connected to the output end of the first hydraulic cylinder 42, the other end of the first sleeve 43 is provided with a mounting countersunk hole, one end of the first fixing sleeve 44 is inserted into the mounting countersunk hole, the other end of the first fixing sleeve 44 is provided with a first countersunk hole for installing a water nozzle, and the first countersunk hole is opposite to the first interface of the motor housing; the output end of the first hydraulic cylinder 42, the first sleeve 43 and the first fixing sleeve 44 are coaxially arranged.
[0045] Meanwhile, a plurality of rubber rings 45 are disposed on the inner wall of the first sleeve 43 , a groove matching the corresponding rubber rings 45 is disposed on the outer wall of the first fixing sleeve 44 , and a buffer gap is disposed between the inner wall of the first sleeve 43 and the outer wall of the first fixing sleeve 44 .
[0046] When the first hydraulic cylinder 42 is working, it pushes the first sleeve 43 and the first fixed sleeve 44 to move in the direction of the motor housing, and the water nozzle pre-installed in the first countersunk hole docks with the first interface of the motor housing. As the first hydraulic cylinder 42 is pushed, one end of the water nozzle is connected with the first interface of the motor housing by interference fit. In order to avoid rigid collision between the water nozzle and the motor housing during docking, multiple rubber rings and buffer gaps are set between the first fixed sleeve 44 and the first sleeve 43 to buffer the rigid collision between the water nozzle and the motor housing. At the same time, multiple rubber rings and buffer gaps make the first sleeve 43 have a floating effect, avoiding the situation where the water nozzle and the first interface have a small deviation and cannot be pressed.

[0049] The first hydraulic cylinder 42 and the second hydraulic cylinder 52 use the same hydraulic control system, so it can be ensured that the first hydraulic cylinder 42 and the second hydraulic cylinder 52 can work at the same time. While the first hydraulic cylinder 42 drives the water nozzle to be installed, the output end of the second hydraulic cylinder 52 pushes the abutment joint to abut against the outer wall of the motor housing, which is used to offset a part of the force of the first hydraulic cylinder 42 on the motor housing, thereby preventing the motor housing from tipping over due to unilateral force and also preventing the motor housing from being deformed due to uneven force.
[0050] The first pair of oil-eliminating cylinders 54 and the second pair of oil-eliminating cylinders 55 further play a role in eliminating force, supporting the lower part of the motor housing to prevent the motor housing from being deformed due to uneven force.
[0051] Specifically, the clamping unit 6 includes a mounting frame 61, a third hydraulic cylinder 62 and a pressing head 63. The mounting frame 61 is arranged on the frame 1. Three third hydraulic cylinders 62 are arranged equidistantly on the mounting frame 61. Three pressing heads 63 are arranged, and the output ends of the third hydraulic cylinders 62 are respectively connected to the corresponding pressing heads 63.
[0052] The three pressure heads 63 are evenly distributed, and the contact points with the upper end of the motor housing are also evenly distributed on the upper end of the motor housing, ensuring that the motor housing can be evenly stressed when pressed, and avoiding the motor housing from tipping over when the faucet is installed. One of the contact points is located directly above the first interface, which can press the motor housing in a vertical direction, providing a certain auxiliary support for the installation of the faucet.

[0054] At the same time, the second nozzle pressure unit 7 also includes a guide rail and a slide seat. The guide rail is arranged on the processing table 2, and the guide rail is located in the radial direction of the motor housing. The slide seat is slidably matched with the guide rail, and the upper end of the slide seat is connected to the water nozzle fixing seat 73.
[0055] An L-shaped water nozzle is pre-installed on the water nozzle fixing seat 73, and the output end of the fourth hydraulic cylinder 72 pushes the water nozzle fixing seat 73 to move toward the motor housing. One end of the water nozzle is directly connected with the second interface on the motor housing through an interference fit. The guide rail and the slide seat are arranged to cooperate, which plays a good guiding role in the movement of the water nozzle fixing seat 73 and ensures that the water nozzle can be accurately docked with the second interface.
