[0030] When the workshop staff installed the measuring tube of the copper tube valve-controlled water meter by the traditional manual plugging method, they found that the measuring tube was skewed when observed from the water outlet, resulting in failure in the meter measurement. Statistics show that the failure rate even reached 5%. In order to solve the problems of measuring tube installation deviation and installation efficiency, this tooling solution was proposed.

[0031] For specific solutions, please refer to the following specific embodiments: Example

[0032] See also Figures 1 to 5 , which is the first embodiment of the utility model, provides an auxiliary device for embedding the measuring tube of an ultrasonic valve-controlled water meter into a copper pipe section, comprising a tooling bottom plate 100 with a flat surface;

[0033] A movable receiving assembly 200 is provided at a port on one side of the tooling bottom plate 100. The movable receiving assembly 200 includes a movable bracket 201 whose bottom is fixed to the surface of the tooling bottom plate 100 by a group of nuts and screws. A first symmetrical boss is provided on the top of the movable bracket 201. A first water outlet top rod 202 is movably connected in the boss spacing space of the first symmetrical boss through a group of bolts and nuts. A second symmetrical boss is provided at the other end of the first water outlet top rod 202. A second water outlet top rod 203 is movably connected in the boss spacing space of the second symmetrical boss through a group of bolts and nuts. A group of symmetrical first auxiliary inserts 204 are provided at the other end of the second water outlet top rod 203.

[0034] A fixed alignment component 300 is fixedly connected to the middle section of the tooling base plate 100 by a set of nuts and screws, and a set of round-tip fixing parts corresponding to the openings of the copper pipe section are arranged on the fixed alignment component 300;

[0035] A top connection assembly 400 is provided at the other end of the tooling bottom plate 100. The top connection assembly 400 includes a base flange 401. A top rod 402 is fixedly connected to the upper end of the base flange 401. The base flange 401 drives the top rod 402 to slide along a surface parallel to the tooling bottom plate 100. The top rod 402, the second water outlet top rod 203 and the first water outlet top rod 202 are in the same vertical plane.

[0036] A group of symmetrical second auxiliary inserts 402a are disposed at the other end of the ejector rod 402.

[0037] The tooling base plate 100 is in a regular rectangular shape.

[0038] Among them, see Figures 6 to 8 The first water outlet top rod 202 can rotate around at a certain angle in the boss spacing space of the first symmetrical boss; the second water outlet top rod 203 can rotate around at a certain angle in the boss spacing space of the second symmetrical boss; when the first water outlet top rod 202 and the second water outlet top rod 203 are both parallel to the surface of the tooling bottom plate 100, the bottom of the limiting hole on the copper pipe section embedded at the end of the second water outlet top rod 203 falls exactly parallel to the surface of the tooling bottom plate 100, and the three are on parallel straight lines.

[0039] During use, see Fig.10 , insert the measuring tube into the water inlet of the copper tube section in advance, and then embed the water outlet of the copper tube section into the second water outlet top rod 203. When it is fully embedded in the limit, move the second water outlet top rod 203 to adjust the limit hole on the copper tube section to align with the fixed alignment component 300, and press to keep the copper tube section level. At this time, since the copper tube section is limited on the second water outlet top rod 203, the first auxiliary insert 204 slightly protrudes out of the limit ring and protrudes toward the side of the top rod 402, maintaining a one-side positioning state, and then pushes the base flange 401 to drive the top rod 402 to slide toward the middle section side in a parallel direction. During the sliding process, the second auxiliary insert 402a is embedded in the groove at one end of the bracket-type valve-controlled measuring tube (it is not necessary to fully embed it initially, and the double-sided positioning is realized after being subjected to pressure in the later stage to achieve limit), and the measuring tube is pushed into the copper tube section until the other end of the measuring tube just reaches the limit ring. At this time, the first auxiliary insert 204 plays a secondary matching role, and the double-sided limit finally realizes precise limit.

[0040] The utility model provides an auxiliary device for embedding a measuring tube of an ultrasonic valve-controlled water meter into a copper tube section. The copper tube section is received by a bending and rotating movable receiving assembly, and the copper tube section is fixed in cooperation with a fixed alignment assembly. The top connection assembly slides, and the measuring tube placed at the port in advance in the copper tube section is pushed into the tube section. The second auxiliary insert is first embedded in a groove at one side port of the measuring tube. In the process of top installation, bidirectional positioning is finally achieved in cooperation with the extended first auxiliary insert, and the non-deviation installation of the measuring tube is completed. The device completes precise installation, and solves the problem of skewed installation of the measuring tube in the existing installation process of the measuring tube of the valve-controlled water meter. Example

[0041] Reference Figures 3 to 8 , which is the second embodiment of the utility model. This embodiment is different from the first embodiment in that the ports of the first auxiliary insert 204 and the second auxiliary insert 402a are flat surfaces, and the other inner surfaces in the circumferential direction are connected with a certain slope, all presenting an expanded arc shape.

[0042] Furthermore, the openings of the first auxiliary insert 204 and the second auxiliary insert 402a are opposite to each other, have the same opening angles, and have the same opening shapes.

[0043] Furthermore, a set of round-tip fixing members are disposed on the connection line between the first auxiliary insert 204 and the second auxiliary insert 402a.

[0044] The remaining structures are the same as those of Example 1.

[0045] It should be noted that the arrangement of the ports of the first auxiliary insert 204 and the second auxiliary insert 402a ensures that the measuring tube can be protected from damage as much as possible when pushed by external force, and the arc-shaped design plays a role of force sliding connection.

[0046] During use, see Fig.10 , insert the measuring tube into the water inlet of the copper pipe section in advance, and then embed the water outlet of the copper pipe section into the second water outlet top rod 203. When it is fully embedded in the limit, move the second water outlet top rod 203, adjust the limit hole on the copper pipe section to align with the fixed alignment component 300, and press to keep the copper pipe section horizontal. At this time, since the copper pipe section is limited on the second water outlet top rod 203, the first auxiliary insert 204 slightly protrudes out of the limit ring and protrudes toward the side of the top rod 402, maintaining a one-side positioning state, and then push the base flange 401 to drive the top rod 402 to be level Slide toward the middle section in the row direction. During the sliding process, the second auxiliary insert 402a is embedded in the groove at one end of the bracket-type valve-controlled measuring tube (it does not need to be fully embedded initially. After being subjected to pressure in the later stage, the double-sided positioning is used to achieve limit. When the measuring tube is subjected to pushing pressure, the expanded arc-shaped end face is forced to slide, which ensures that the measuring tube is not easily damaged inside the copper tube. It can be directly snapped in after sliding under force), and the measuring tube is pushed into the copper tube section until the other end of the measuring tube just reaches the limit ring. At this time, the first auxiliary insert 204 plays a secondary matching role, and the double-sided limit finally achieves precise limit.

[0047] The utility model provides an auxiliary device for embedding a measuring tube of an ultrasonic valve-controlled water meter into a copper tube section. The copper tube section is received by a bending and rotating movable receiving assembly, and the copper tube section is fixed in cooperation with a fixed alignment assembly. The top connection assembly slides, and the measuring tube placed at the port in advance in the copper tube section is pushed into the tube section. The second auxiliary insert is first embedded in a groove at one side port of the measuring tube. In the process of top installation, bidirectional positioning is finally achieved in cooperation with the extended first auxiliary insert, and the non-deviation installation of the measuring tube is completed. The device completes precise installation, and solves the problem of skewed installation of the measuring tube in the existing installation process of the measuring tube of the valve-controlled water meter. Example

[0048] Reference Figure 4 and Fig. 9, which is the third embodiment of the utility model. This embodiment is different from the second embodiment in that it also includes a pneumatic component 500 arranged directly below the fixed alignment component 300. The pneumatic component 500 includes a pneumatic bracket 501 fixedly connected to the bottom surface of the tooling base plate 100 through a group of nuts and screws, a cylinder 502 and a cylinder rod 503 that cooperate with each other, and a solenoid valve 504 fixedly connected to the bottom surface of the tooling base plate 100 for controlling the operation of the cylinder and the cylinder rod. An opening is provided on the pneumatic bracket 501, a connecting rod is inserted through the opening and fixedly connected to one end of the base flange 401, and the other end is movably inserted into the opening, and the other end of the cylinder rod 503 is fixedly connected to the base flange 401, driving the base flange 401 to move parallel to the movement direction of the cylinder rod 503, and the movement direction of the cylinder rod 503 is parallel to the surface of the tooling base plate 100.

[0049] Furthermore, the pneumatic assembly 500 and the top assembly 400 are both semi-enclosed by a cylinder cover, and the cylinder cover includes an upper cylinder cover for covering the top assembly 400 and a lower cylinder cover for covering the pneumatic assembly 500, and the upper cylinder cover and the lower cylinder cover are both fixed to the tooling base plate 100 by nuts and screws. The cylinder cover plays a role in protecting the cylinder.

[0050] The remaining structure is the same as that of Example 2.

[0051] During use, see Fig.10 , insert the measuring tube into the water inlet of the copper pipe section in advance, and then embed the water outlet of the copper pipe section into the second water outlet top rod 203. When it is fully embedded in the limit, move the second water outlet top rod 203, adjust the limit hole on the copper pipe section to align with the fixed alignment component 300, and press to keep the copper pipe section horizontal. At this time, since the copper pipe section is limited on the second water outlet top rod 203, the first auxiliary insert 204 slightly protrudes out of the limit circle and protrudes toward the side of the top rod 402, maintaining a positioning state on one side, and then start the pneumatic component 500, the solenoid valve 504 controls the cylinder 502 to operate, driving the cylinder rod 503 to contract, driving The base flange 401 contracts, driving the top rod 402 to slide toward the middle section in a parallel direction. During the sliding process, the second auxiliary insert 402a is embedded in the groove at one end of the bracket-type valve-controlled measuring tube (it does not need to be fully embedded initially, and the double-sided positioning is realized after being subjected to pressure in the later stage. When the measuring tube is subjected to pushing pressure, the expanded arc-shaped end face is forced to slide, ensuring that the measuring tube is not easily damaged inside the copper tube. It can be directly snapped in after being forced to slide), and the measuring tube is pushed into the copper tube section until the other end of the measuring tube just reaches the limit ring. At this time, the first auxiliary insert 204 plays a secondary matching role, and the double-sided limit finally realizes precise limit.

[0052] The utility model provides an auxiliary device for embedding a measuring tube of an ultrasonic valve-controlled water meter into a copper tube section. The copper tube section is received by a bending and rotating movable receiving assembly, and the copper tube section is fixed in cooperation with a fixed alignment assembly. The pneumatic assembly is started, and the cylinder rod is compressed to drive the top connection assembly to retract, so that the measuring tube previously placed at the port in the copper tube section is pushed into the tube section. The second auxiliary insert is first embedded in a groove at one side port of the measuring tube, and in the process of completing the top installation, bidirectional positioning is finally achieved in cooperation with the extended first auxiliary insert, and the non-deviation installation of the measuring tube is completed. The device realizes automated auxiliary installation, completes precise installation, and saves labor costs, and solves the problem of skewed installation of the measuring tube in the existing valve-controlled water meter measuring tube installation process.

[0053] It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
