[0025] like Figures 1 to 5 As shown, this utility model discloses a tooling for aligning the core of a temperature-controlled valve.

[0026] like Figure 1As shown, the temperature-controlled valve core alignment fixture includes a tool holder 1. The tool holder 1 is equipped with a positioning bracket 2, a first pin 3, a second pin 4, and a third pin 5, all of which have the same outer diameter. The positioning bracket 2, first pin 3, second pin 4, and third pin 5 are detachably mounted on the tool holder 1, allowing for easy removal of these components.

[0027] In some embodiments of this example, one end of the first pin 3 is provided with a push rod portion, which is used to push the valve seat 9 and the spindle 10 during installation; one end of the second pin 4 is provided with a detection portion, which is used to detect whether the valve seat 9 and the spindle 10 guide sleeve 8 on the valve base 7 are coaxial during installation of the valve seat 9 and the spindle 10.

[0028] like Figure 2 As shown, the positioning bracket 2 includes a flat plate 21, and an inverted U-shaped support 22 is provided on the upper surface of the flat plate 21. The inverted U-shaped support 22 includes two vertical sections and a top wall located between the two vertical sections. The two opposite sidewalls of the top wall are respectively connected to the top of the two vertical sections. A first through hole is formed in the top wall of the inverted U-shaped support 22, which penetrates the top wall of the inverted U-shaped support 22 in the vertical direction. A protective tube 6 is embedded in the first through hole, and the inner diameter of the protective tube 6 is equal to the outer diameter of the first pin 3, the second pin 4, and the third pin 5. A second through hole is formed on the flat plate 21, which penetrates the flat plate 21 in the vertical direction; the first through hole is located directly above the second through hole, and the second through hole is coaxial with the protective tube 6, and the inner diameter of the second through hole is equal to the inner diameter of the protective tube 6.

[0029] In this embodiment, the process of assembling the valve seat 9 and the spindle 10 using the temperature-controlled valve core alignment fixture is as follows: First, one end of the third pin 5 is passed through the protective sleeve and the second through hole in sequence. Then, the valve base 7 is installed on the lower surface of the plate 21 of the positioning bracket 2, ensuring that the protective tube 6 is coaxial with the spindle 10 and the guide sleeve 8 on the valve base 7. Figure 3 As shown. Then remove the third pin 5, install the valve seat 9 into the second through hole, and then use the first pin 3 to push the valve seat 9 into the corresponding mounting slot on the valve base 7 for installation. Then remove the first pin 3, and use the second pin 4 to check whether the valve seat 9 and the spindle 10 and the guide sleeve 8 are coaxial. Figure 4 As shown. Remove the second pin 4 and valve seat 9, insert the spindle 10 into the second through hole, and then use the first pin 3 to push the spindle 10 into the corresponding mounting slot on the valve base 7 for installation. Then remove the first pin 3. Next, insert the valve seat 9 into the second through hole, and then use the first pin 3 to push the valve seat 9 into the corresponding mounting slot on the valve base 7 for installation, as shown. Figure 5As shown. Remove the first pin 3, and then remove the valve base 7 from the positioning bracket 2.

[0030] In some embodiments of this example, the tool holder 1 has a first fixing hole, a second fixing hole, and a third fixing hole. The first pin 3 is inserted into the first fixing hole with a clearance fit, allowing for easy insertion and removal of the first pin 3. The second pin 4 is inserted into the second fixing hole with a clearance fit, allowing for easy insertion and removal of the second pin 4. The third pin 5 is inserted into the third fixing hole with a clearance fit, allowing for easy insertion and removal of the third pin 5.

[0031] In some embodiments of this example, a first annular body is nested on the side wall of the first pin 3. The outer diameter of the first annular body is larger than the inner diameter of the first fixing hole, which prevents the first pin 3 from being fully inserted into the first fixing hole, making it easier to remove the first pin 3 from the first fixing hole. The first annular body is integrally formed with the first pin 3 or welded to the side wall of the first pin 3. Similarly, a second annular body is nested on the side wall of the second pin 4. The outer diameter of the second annular body is larger than the inner diameter of the second fixing hole, which prevents the second pin 4 from being fully inserted into the second fixing hole, making it easier to remove the second pin 4 from the second fixing hole. The second annular body is integrally formed with the second pin 4 or welded to the side wall of the second pin 4. A third ring is nested on the side wall of the third pin 5. The outer diameter of the third ring is larger than the inner diameter of the third fixing hole, which can prevent the third pin 5 from being completely installed in the third fixing hole and facilitate the removal of the third pin 5 from the third fixing hole. The third ring is integrally formed with the third pin 5 or the third ring is welded to the side wall of the third pin 5.

[0032] In some embodiments of this example, the protective tube 6 includes a tube body with an outer diameter equal to the inner diameter of the first through hole. The tube body is embedded in the first through hole, and a fourth annular body is nested on the top outer wall of the tube body. The outer diameter of the fourth annular body is larger than the inner diameter of the first through hole. A first groove is formed on the upper surface of the top wall of the inverted U-shaped support 22, and the first through hole is located at the bottom of the first groove. The lower surface of the fourth annular body is fitted to the bottom of the first groove. The fourth annular body is integrally formed with the tube body or welded to the outer wall of the tube body.

[0033] The protective tube 6 can be made of metal, such as copper tube or aluminum alloy tube. The protective tube 6 can prevent the first pin 3, the second pin 4 and the third pin 5 from directly contacting the inner wall of the first through hole during use, thus extending the service life of the tooling.

[0034] In some embodiments of this example, the outer side of the top wall of the inverted U-shaped support 22 is provided with multiple first threaded holes, and a third ring is nested on the side wall of the third pin 5. The outer diameter of the third ring is larger than the inner diameter of the third fixing hole, and multiple second threaded holes corresponding to the first threaded holes are provided on the third ring. After the third pin 5 is inserted through the protective tube 6, the third pin 5 is rotated so that the first threaded holes correspond to the second threaded holes. Then, screws are used to pass through the second threaded holes and the first threaded holes in sequence to stably and detachably fix the third pin 5 to the positioning bracket 2.

[0035] In some embodiments of this example, the lower surface of the plate 21 is provided with a plurality of third threaded holes, so that the valve base 7 can be stably and detachably fixed to the positioning bracket 2 using screws.

[0036] In some embodiments of this example, the tool holder 1 includes a tool base, a support plate is vertically arranged on the tool base, a bearing plate is horizontally arranged on the top of the support plate, a third through hole is opened on the bearing plate, the third through hole penetrates the bearing plate in the vertical direction, the inner diameter of the third through hole is larger than the inner diameter of the second through hole, the positioning bracket 2, the first pin 3, the second pin 4 and the third pin 5 are located on the bearing plate, and the second through hole is located directly above the third through hole.

[0037] In some embodiments of this example, the upper surface of the support plate is provided with a second groove, the third through hole is located at the bottom of the second groove, the plate 21 of the positioning bracket 2 is embedded in the second groove, and the lower surface of the plate 21 is in contact with the bottom of the second groove.

[0038] In some embodiments of this example, the first fixing hole, the second fixing hole, and the third fixing hole penetrate the support plate in the vertical direction.

[0039] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of this utility model. It should be understood that the above description is only a specific embodiment of this utility model and is not intended to limit the scope of protection of this utility model.
