[0018] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.
[0019] like Figures 1 to 4 As shown in this embodiment, a tight-fitting FIN fixing fixture includes a base 1, a cylinder 2, a fixed side plate 3, a movable side plate 4, and a quick clamp 5. The cylinder 2 is fixed to the lower end of the base 1, the fixed side plate 3 is fixed to one side of the base 1, the moving arm of the cylinder 2 is connected to the movable side plate 4, the movable side plate 4 is located on the other side of the base 1, a lower contoured heat pipe groove 6 is provided in the middle of the base 1, and side contoured heat pipe grooves 7 are provided on the inner side of both the fixed side plate 3 and the movable side plate 4. A pressure block 9 is connected to the quick clamp 5.
[0020] When the heat pipe 14 is placed on the base 1, the fixed side plates 3 and the movable side plates 4 on both sides approach each other, clamping and fixing the sides of the heat pipe 14. The pressure block 9 presses down and fixes it from above, forming a four-way positioning, so that the fin-through process can be performed, that is, the fin 13 can be installed.
[0021] Furthermore, the quick-release chuck 5 is swung and connected to a handle 10, and both sides of the base 1 are formed with V-shaped dovetail guide posts 11. The lower ends of the fixed side plate 3 and the movable side plate 4 are provided with dovetail grooves. The V-shaped dovetail guide posts 11 are assembled and connected with the dovetail grooves. The movable angle between one side of the pressure block 9 and the quick-release chuck 5 is 90°. The lower end of the pressure block 9 is provided with two protective rubbers 12, which are located at both ends of the lower conformal heat pipe groove 6.
[0022] The assembly of the V-shaped dovetail guide post 11 and the dovetail groove forms a V-shaped fit, which can prevent rotational wobbling and ensure parallel displacement between the fixed side plate 3 and the movable side plate 4. The pressure block 9 has an upper contoured heat pipe groove 8. In the initial state, the quick clamp 5 is in the open state, and air pressure supplies air to the air inlet of the cylinder 2. The moving arm of the cylinder 2 controls the movable side plate 4 to move outward, and the two side plates form a large U-shaped space. When the heat pipe 14 is placed in the lower contoured heat pipe groove 6, the first orientation is completed, and air is supplied to the cylinder 2 in the opposite direction. The moving arm of the cylinder controls the movable side plate 4 to move inward, and the side contoured heat pipe groove 7 of the movable side plate 4 and one side of the heat pipe 14 are aligned. The heat pipe 14 is fitted and clamped to the side profile heat pipe groove 7 of the fixed side plate 3 to complete the second and third orientations. Then, the handle 10 is moved 90° from the vertical angle, so that the pressure block 9 rotates 90°. The upper profile heat pipe groove 8 and the lower profile heat pipe groove 6 of the base 1 form a bidirectional compression of the heat pipe 14, completing the four-way positioning of the heat pipe 14. Then, the fixture is placed on a special FIN machine to complete the tight fitting and FIN process. Finally, the air is supplied in the opposite direction, and the cylinder 2 controls the moving arm to move outward, driving the movable side plate 4 away from the base 1. The handle 10 is pulled in the opposite direction, and the pressure block 9 returns to the vertical position, forming an L-shaped open positioning. The heat pipe 14 product can then be taken out.
[0023] It should be stated that the above-described specific embodiments are merely preferred embodiments of this utility model and the technical principles applied thereto. Within the scope of the technology disclosed in this utility model, any variations or substitutions that are easily conceived by those skilled in the art should be covered within the protection scope of this utility model.
