The liquid passing sleeve body 610 comprises an inner cavity 611, the inner cavity 611 extends along the axial direction of the liquid passing sleeve body 610 and penetrates through the liquid passing sleeve body 610, an upper port 613 and a lower port 614 are respectively arranged at two sides of the inner cavity 611, and two liquid outlet holes 612 penetrating through the side wall along the radial direction of the inner cavity 611 are arranged on the side wall forming the inner cavity 611.
Currently, the liquid passing sleeve 600 is mainly assembled in a manual assembly mode. Practical results show that, on the one hand, in the process that the first sealing ring 620 is pressed to the inner cavity bottom 615 of the inner cavity 611, the first sealing ring 620 is easily scratched by burrs at the liquid outlet holes 612 when passing through the liquid outlet holes 612. On the other hand, in the process of pressing the balance jack 650 into the inner cavity 611 after the first seal ring 620 is pressed to the inner cavity bottom 615 of the inner cavity 611, the jack end 651 of the balance jack 650 easily scratches the first seal ring 620, which results in defective assembly.

and a balance ejector rod pressing step of pressing the balance ejector rod 650 into the inner cavity 611, and ejecting the guide needle 50 through the balance ejector rod 650 in the pressing process so that the balance ejector rod 650 penetrates through the first sealing ring 620.
Compared with the traditional liquid passing sleeve assembling method, in the liquid passing sleeve assembling method of the embodiment of the application, on one hand, the first sealing ring 620 firstly enters the inner cavity 611 in an inclined manner, so that the first sealing ring can be prevented from being scratched when passing through the liquid outlet 612; on the other hand, the guide pin 50 is used to open the inner hole of the first sealing ring 620, so as to balance the open circuit of the top rod end 651 of the top rod 650, so that the top rod end 651 will not scratch the first sealing ring 620 when passing through the first sealing ring 620. Therefore, by using the liquid passing sleeve assembling method of the embodiment, the scratch damage to the first sealing ring 620 can be relieved in the assembling process, and the product yield of the assembled liquid passing sleeve 600 is further improved.

A guide needle pressing step: the tip 51 of the guide needle 50 is downwardly inserted into the guide hole 11, the manipulator 30 lowers the flat needle 42, and the flat needle 42 is used to press down the guide needle 50 such that the tip 51 of the guide needle 50 passes through the first seal ring 620.
A step of pressing a balance ejector rod: the balance ejector rod 650 is placed into the guide hole 11, the manipulator 30 drives the plain needle 42 to descend, the plain needle 42 is used for pressing down the balance ejector rod 650, the end portion 651 of the ejector rod is abutted to the tail end 52 of the guide needle 50, the end portion 651 of the ejector rod pushes the guide needle 50 to move downwards, the guide needle 50 is ejected out, the guide needle 50 falls from the needle outlet 242, the end portion 651 of the ejector rod penetrates through the first sealing ring 620 along with the guide needle 50, assembly of the balance ejector rod 650 and the first sealing ring 620 is completed, and accordingly assembly of the whole liquid passing sleeve 600 is completed.
Optionally, a collecting box is disposed at a lower end of the needle outlet 242 to collect the guide needle 50 dropped from the needle outlet 242 to recycle the guide needle 50.
Further, the "second seal ring press-in step" and the "guide pin press-in step" are located between the "copper bush press-in step" and the "balance pin press-in step" for placing the second seal ring 640 and the guide pin 50 into the inner cavity 611. The sequence of assembling the second sealing ring 640 and placing the guide needle 50 can be flexibly adjusted according to specific requirements.
Referring to fig. 11, as an exemplary form, the "second seal ring press-fitting step" is performed after the "guide pin press-fitting step", i.e., the guide pin 50 is pressed in, and then the second seal ring 640 is pressed in. As can be readily appreciated, the pin end 651 can be "opened" by the tip 51 of the guide pin 50 opening the inner bore of the first seal 620, thereby allowing the pin end 651 to pass smoothly through the first seal 620.
Correspondingly, in the "guide needle pressing step", the guide needle 50 passes through the first seal ring 620 and the copper bush 630; in the "balance plunger pressing step", the plunger end 651 of the balance plunger 650 passes through the first seal ring 620 and the copper bush 630 under the guide of the guide pin 50, and then the "second seal ring pressing step" is performed to press the second seal ring 640 into the inner cavity 611.
Based on the method of pressing the guide pin 50 first and then the second sealing ring 640 ", optionally, in the" guide pin pressing step ", the tail end plane 521 of the guide pin 50 is pushed to be flush with the upper end surface of the copper sleeve 630. As will be readily appreciated, this arrangement facilitates the smooth implementation of the "second seal ring pressing step".
Referring to fig. 12, as another exemplary form, the "second seal ring pressing step" is performed before the "guide pin pressing step", i.e., the second seal ring 640 is pressed in and then the guide pin 50 is pressed in.
As will be readily understood, in the "guide needle pressing step", the tip 51 of the guide needle 50 passes through the first seal ring 620, the copper bush 630 and the second seal ring 640; in the "balance ram pressing step", the ram end 651 passes through the first seal ring 620, the copper bush 630, and the second seal ring 640. With this arrangement, the guide pin 50 further opens the inner hole of the second seal ring 640 based on the inner hole of the first seal ring 620, thereby opening the way for the top rod end 651, so that the top rod end 651 can pass through the first seal ring 620 and the second seal ring 640 smoothly.
In some embodiments of the present application, the feeding of the components that make up the liquid jacket 600 is performed manually. In other embodiments, a corresponding automatic feeding device can be arranged to replace manual feeding, so as to further improve the assembly efficiency.
In some embodiments of the present application, the diameter of the bevel needle 41 is the same as that of the flat needle 42. when the bevel needle 41 or the flat needle 42 is inserted into the cavity 611, the fit clearance △ between the press-fitting needle 40 and the cavity 611 is less than or equal to 0.04mm, so as to ensure that the component is accurately pressed down.
It should be noted that the liquid passing set assembling apparatus 100 in the embodiment of the present application is an exemplary apparatus for assembling the liquid passing set 600 based on the liquid passing set assembling method in the embodiment of the present application. In other embodiments, other devices may be used to implement the liquid passing set assembly method in the present example.
Compared with the existing assembly method, the liquid passing sleeve assembly method provided by the embodiment of the application has the advantages that on one hand, the degree of scratching of the outer side of the first sealing ring 620 is relieved by the method of matching the inclined needle 41 and the flat needle 42; on the other hand, by using the guide pin 50, the degree of scratching of the inner bore and the upper surface of the first seal ring 620 is alleviated. Therefore, the assembly of the liquid passing sleeve 600 is performed by using the liquid passing sleeve assembling method provided by the embodiment of the application, so that the scratch degree of the first sealing ring 620 can be relieved, and the assembly qualification rate of the liquid passing sleeve 600 is further improved.
It should be noted that the features of the embodiments in the present application may be combined with each other without conflict.
The above description is only a preferred embodiment of the present application and is not intended to limit the present application, and various modifications and changes may be made by those skilled in the art.
