Description

Technical Field

[0001] The utility model belongs to the technical field related to radiators, and particularly relates to a strength detection fixing tool. Background Art

[0002] Radiator is a device used for heat dissipation, which dissipates heat to the outside world to ensure the normal operation of the corresponding equipment. Generally speaking, radiators are divided into tube-fin radiators and tube-belt radiators. The tube-belt radiator uses a heat dissipation belt to dissipate heat. It can be used in conjunction with pipes or independently (such as using heat dissipation belts in various headlights). Therefore, the use of heat dissipation belts must be tested for strength before leaving the factory. However, there are still the following disadvantages in the strength test of heat dissipation belts:

[0003] The strength test of the heat dissipation belt must be assisted by a certain fixed tooling. For example, for tensile strength test, the corresponding tooling must have a certain fixed and adjustable function. The heat dissipation belt is different from the heat sink. It is mostly made of metal weaving and has a certain flexibility. Usually, more samples need to be tested during factory inspection. However, there is still a lack of fixed tooling on the market that can test multiple samples at the same time.

[0004] Secondly, in addition to its own tensile strength, the heat sink also has its own heat dissipation strength. In order to ensure its heat dissipation performance is qualified, it must be tested. However, it is difficult to test the heat dissipation effect when the heat sink is not installed on the radiator before leaving the factory. If it is assembled into a radiator and then tested, it will be too costly. Utility Model Content

[0026] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0027] See also Figure 1-5 As shown, the utility model is a strength detection fixture, including a base plate 1, two frames 2, a movable plate 3 and a heating frame 4, the frames 2 are fixed at both ends of the base plate 1, and the adjusting screws 101 are rotatably connected in both ends of the base plate 1, the threaded sections of the two adjusting screws 101 are commonly threadedly connected with the movable plate 3, and the movable plate 3 is located between the two frames 2, and the base plate 1 is fixed with base blocks 102 distributed at equal intervals on one side of the base plate 1 close to the movable plate 3, and the side of the base plate 1 above each base block 102 is also fixed with base blocks 2 103, and the base blocks 2 103 are screwed with locking screws 104;

[0028] A base plate 1 and two frames 2 are fixed to form a main structure. An adjusting screw 101 is arranged in the base plate 1, and the adjusting screw 101 is used to screw the movable plate 3 to change its position. The movable plate 3 is restricted by the two adjusting screws 101, and the two ends are restricted in the slide groove 202 by the slider 302, and can only move horizontally; secondly, when fixing the corresponding heat dissipation belt, the two ends of the heat dissipation belt are folded and aligned, and placed between the base block 1 102 and the base block 2 103 on the same vertical line, and the locking screw 104 is rotated and lowered until the pressing block 1041 presses the end of the heat dissipation belt, so that it is fixed between the pressing block 1041 and the upper end surface of the base block 102, and the initial fixed use is completed;

[0029] The movable plate 3 is fixed with equidistantly distributed fixing blocks 301 on one side close to the base plate 1, and each fixing block 301 is fixed with a hook 3011 on one end away from the movable plate 3;

[0030] After the heat dissipation belt is fixed, its bent portion is sleeved outside the draw hook 3011 on the corresponding fixing block 301, and it is hooked and tightened;

[0031] A heating frame 4 is provided on the side of the substrate 1 away from the activity, and an electric heating tube 401 is fixed in the heating frame 4;

[0032] The electric heating tube 401 is arranged in the heating frame 4 to provide a heat source for use in the heat dissipation intensity detection. The heat is transferred to the heat dissipation belt. Then, according to factors such as the temperature and rate of heat dissipation of the heat dissipation belt, the heat dissipation efficiency of the heat dissipation belt can be understood and qualified data can be quickly obtained.

[0033] A slide groove 202 is provided on one side of the frame 2 close to the movable plate 3, and sliders 302 are fixed at both ends of the movable plate 3, and the sliders 302 are slidably arranged in the corresponding slide grooves 202;

[0034] The movable plate 3 slides in the slide groove 202 through the slider 302, further achieving position limiting and stable movement to ensure that there is no deviation.

[0035] A motor 201 is fixed to the side of the frame 2 away from the base plate 1, and a driving gear 2011 is fixed to the output shaft of the motor 201. A driven gear 1012 is fixed to the end of the adjusting screw 101 away from the movable plate 3, and the driving gear 2011 and the driven gear 1012 are meshed and connected; a limiting block 1011 is fixed to the end of the adjusting screw 101 away from the driven gear 1012;

[0036] The motor 201 drives the active gear 2011 to rotate, meshing with the driven gear 1012 to rotate, thereby rotating the adjusting screw 101, thereby changing the position of the movable plate 3 and causing it to move horizontally. Secondly, the setting of the limit block 1011 limits the maximum movable stroke of the movable plate 3 to avoid disengagement.

[0037] A through slot 105 is provided in the substrate 1 , and the base block 1 102 is lower than the through slot 105 , and the base block 2 103 is higher than the through slot 105 . The heating frame 4 has an opening on one side close to the substrate 1 , and the opening is connected to the through slot 105 .

[0038] The upper end surface of the base block 102 is flush with the lower end surface of the fixed block 301, and a pressing block 1041 is fixed to the bottom end of the locking screw 104; the locking screw 104 is rotated to move the adjusting screw 101 downward to cooperate with the base block 102 to press the end of the heat dissipation belt.

[0039] A hook 402 is fixed on the side of the top surface of the heating frame 4 close to the substrate 1, and the tail end of the hook 402 is hooked in the upper surface of the substrate 1; the setting of the hook 402 temporarily forms a certain connection between the heating frame 4 and the substrate 1 to avoid separation from each other during operation.

[0040] The specific working principle of the utility model is as follows: first, fold and align the two ends of the heat dissipation belt, place them between the base block 102 and the base block 103 on the same vertical line, rotate the locking screw 104 downward until the pressing block 1041 presses the end of the heat dissipation belt, so that it is fixed between the pressing block 1041 and the upper end surface of the base block 102. After the heat dissipation belt is fixed, the bent portion is sleeved on the outside of the corresponding hook 3011 on the fixed block 301. At this time, the motor 201 drives the active gear 2011 to rotate, and the meshing transmission driven gear 1012 rotates, so that the adjusting screw 101 rotates, and then the position of the movable plate 3 is changed. The movable plate 3 is away from the base plate 1, and the hook 3011 hooks the heat dissipation belt to stretch it, so as to detect its tensile strength.

[0041] Secondly, when testing the heat dissipation intensity, the heating frame 4 is placed close to the substrate 1, and the electric heating tube 401 inside it works to generate heat, which is then conducted to the heat dissipation belt. At this time, the temperature of each bending part of the heat dissipation belt and the corresponding rate of change are detected to know the heat dissipation intensity and heat dissipation effect.
