[0028] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0029] Reference Figure 1-6 , this embodiment provides a cooling chassis vibration tooling.

[0030] The cooling chassis vibration tooling includes two side support plates 5 and a wedge-shaped locking assembly 10, the cooling chassis 2 is located between the two side support plates 5, and the wedge-shaped locking assembly 10 is used to provide a horizontal clamping force for the cooling chassis 2. The side support plates 5 are fixed on the vibration table, and the wedge-shaped locking assembly 10 is arranged on the side support plates 5.

[0031] Specifically, the side support plates 5 are flat plate structures, and the two side support plates 5 are parallel to each other (the distance between the two side support plates 5 is slightly larger than the length of the cooling chassis 2), and the outer sides thereof are provided with ridges that are wider at the bottom and narrower at the top, which increase the overall rigidity of the side support plates 5 and prevent them from deformation.

[0032] The wedge locking assembly 10 can be arranged on one of the two side support plates 5, or on both side support plates 5; one wedge locking assembly 10 can be arranged on one side support plate 5, or multiple wedge locking assemblies 10 can be arranged on one side support plate 5; the wedge locking assembly 10 can be arranged horizontally or vertically. For ease of understanding, the following takes the arrangement of one wedge locking assembly 10 on one side support plate 5 as an example to introduce the specific structure of the wedge locking assembly 10 in detail (such as Figure 1 As shown, four wedge-shaped locking assemblies 10 are horizontally arranged on each side support plate 5).

[0033] Two inclined grooves are provided on the inner side of the side support plate 5 (close to the side of the chassis), and the two inclined grooves are located on the same horizontal plane. For the convenience of installation, the horizontal position of the inclined groove is preferably close to the end of the side support plate 5, and the vertical height position of the inclined groove is preferably slightly smaller than the height of the cooling chassis 2. The wedge-shaped locking assembly 10 is placed in the inclined groove. A through waist-shaped hole (waist hole) is provided on the inclined surface of the inclined groove.

[0034] The wedge-shaped locking assembly 10 includes a first slider 10-1, a second slider 10-2 and a hexagon socket screw 10-4. The hexagon socket screw 10-4 is preferably of M5x120 specification. The first slider 10-1 and the second slider 10-2 are respectively located on both sides of the through waist hole on the side support plate 5. The hexagon socket screw 10-4 passes through the waist hole on the side support plate 5. The hexagon socket screw 10-4 passes through the second slider 10-2, the waist hole and the first slider 10-1 (such as Figure 2 As shown), the hexagon socket combination screw 10-4 can slide freely longitudinally and transversely in the waist hole.

[0035] The first slider 10-1 and the second slider 10-2 have the same external shape, both are rectangular blocks, and the surfaces of the two that contact the inclined surface of the inclined surface groove of the side support plate 5 are inclined surfaces, and the inclined surfaces of the two are parallel to the inclined surface of the inclined surface groove of the side support plate 5. The inclined surfaces of the first slider 10-1 and the second slider 10-2 can slide along the inclined surfaces of the inclined surface groove, so that the first slider 10-1 and the second slider 10-2 can slide and protrude from the plate surface of the side support plate 5.

[0036] A through second slider hole is provided on the inclined surface of the second slider 10-2, the inner diameter of the second slider hole is larger than the outer diameter of the hexagon socket combination screw 10-4, the head size of the hexagon socket combination screw 10-4 is larger than the inner diameter of the second slider 10-2, and the hexagon socket combination screw 10-4 can slide freely in the hole of the second slider 10-2.

[0037] A first slider hole is also provided on the inclined surface of the first slider 10 - 1 , and a thread is provided in the first slider hole. The hexagon socket combination screw 10 - 4 passes through the waist hole and is threadedly connected with the first slider 10 - 1 .

[0038] The working principle of the wedge locking assembly 10 is as follows: Figure 3The figure shows the initial state. The hexagon socket screw 10-4 is rotated clockwise. Through the threaded cooperation between the hexagon socket screw 10-4 and the first slider 10-1, the first slider 10-1 can be moved closer to the second slider 10-2. When the head of the hexagon socket screw 10-4 contacts the second slider 10-2, the hexagon socket screw 10-4 is further rotated clockwise to move the second slider 10-2 closer to the first slider 10-1. The first slider 10-1 and the second slider 10-2 slide along the inclined surface and protrude toward the inner side of the side support plate 5 (as shown in FIG. Figure 4 As shown), a horizontal clamping force is applied to the cooling chassis 2.

[0039] When in use, first fix one side support plate on the vibration table, then place the cooling chassis on the inside of the side support plate, then fix the other side support plate to the vibration table, and then tighten the wedge-shaped locking assembly 10 to clamp the cooling chassis. At this time, the cooling chassis is fixed to the vibration table by two side support plates, and the vibration table can be started for testing.

[0040] Furthermore, the vibration tooling also includes a rear support 12, which is connected to the two side support plates 5 by fastening bolts to form a "U"-shaped frame. The cooling chassis 2 is placed in the "U"-shaped frame. In order to prevent the rear support 12 from directly contacting the cooling chassis 2 and causing the outer side of the cooling chassis 2 to be damaged by friction during vibration, a cooling chassis rear plastic strip 11 is provided on the side of the rear support 12 close to the cooling chassis. The strip material is polytetrafluoroethylene, and the strip material in the entire embodiment is polytetrafluoroethylene.

[0041] The width of the side support plate 5 is slightly smaller than that of the standard cooling chassis 2. A front pressure block 4 for the cooling chassis is fixedly provided at one end of the two side support plates 5 away from the rear support 12. A portion of the front pressure block 4 for the cooling chassis protrudes from the side support plate 5 and presses on the front end of the cooling chassis 2. A front plastic pressure strip 3 for the cooling chassis is provided between the front pressure block 4 for the cooling chassis and the cooling chassis 2. The front plastic pressure strip 3 for the cooling chassis is fixed to the front pressure block 4 for the cooling chassis by fastening bolts, and the fastening bolts will not protrude from the front plastic pressure strip 3 for the cooling chassis after installation. The front pressure block 4 for the cooling chassis is fixed to the side support plate 5 by fastening bolts. By tightening the fastening bolts, a horizontal clamping force can be applied to the front end of the cooling chassis 2. Through the cooperation of the rear support 12, the front and rear directions of the cooling chassis 2 are fixed.

[0042] Furthermore, the height of the side support plate 5 is greater than the height of the standard cooling chassis 2. A hole is provided at the position where the upper end of the side support plate 5 is flush with the cooling chassis. A cooling chassis upper pressing block 7 is installed in the hole by fastening bolts. A part of the cooling chassis upper pressing block 7 protrudes from the side support plate 5 and presses on the cooling chassis 2. A cooling chassis upper plastic pressure strip 6 is provided between the cooling chassis upper pressing block 7 and the cooling chassis 2. By tightening the fastening bolts, a vertical clamping force can be applied to the upper top surface of the cooling chassis 2 to fix the cooling chassis 2 in the up and down directions.

[0043] The vibration tooling also includes an upper cover plate 8 and a base 1. The upper cover plate 8 is mainly used to ensure the overall rigidity of the entire vibration tooling and prevent deformation during vibration. The base 1 is used to fix the entire vibration tooling on the vibration table on the basis of ensuring the overall rigidity of the entire vibration tooling.

[0044] Limiting bosses 9 are provided at both ends of the side support plate 5, and grooves are provided at the positions corresponding to the limiting bosses 9 on the base 1. Through holes are provided at the positions corresponding to the limiting bosses 9 on the upper cover plate 8. The limiting bosses 9 at the lower ends of the side support plates 5 are placed in the corresponding grooves on the base 1, and the limiting bosses 9 at the upper ends of the side support plates 5 are placed in the corresponding through holes on the upper cover plate 8. The two ends of the upper cover plate 8 are respectively fixed to the two side support plates 5 by fastening bolts (to prevent the upper cover plate 8 from being thrown out due to the whip effect during vibration). A groove is also provided at the position corresponding to the rear support 12 of the base 1, and a part of the rear support 12 is placed in the corresponding groove. The rear support 12 and the upper cover plate 8 are fixedly connected to the two side support plates 5 to form a whole. The lower end of the rear support 12 is embedded in the base 1, and the lower ends of the two side support plates 5 are connected to the base 1 through the limiting bosses 9, and the base 1 is fixed to the vibration table by fastening bolts. A pressure strip is also provided between the cooling chassis and the base 1 to prevent the chassis from being damaged by friction.

[0045] When in use, first put the lower limit bosses 9 of the two side support plates 5 into the corresponding grooves of the base 1, and then put the rear support 12 into the corresponding grooves of the base 1, and then fix the rear support 12 with the pressure strip to the two side support plates 5 by tightening the bolts. At this time, the two side support plates 5, the rear support 12 and the base 1 form a fixed frame. Put the standard cooling chassis 2 into the fixed frame, and then adjust the wedge-shaped locking assembly 10 on the side support plates 5 to clamp the cooling chassis in the horizontal direction, and then fix the front pressure block 4 of the cooling chassis with the pressure strip on the side support plates 5 to lock the cooling chassis front and back, and then fix the upper pressure block 7 of the cooling chassis with the pressure strip on the side support plates 5 to lock the cooling chassis up and down, and then fix the upper cover plate 8 to the side support plates 5, and finally fix the base 1 on the vibration table to carry out the vibration simulation experiment.
