Description

Technical Field

[0001] The utility model relates to the technical field of heat dissipation fin positioning, in particular to a tooling fixture for auxiliary positioning. Background Art

[0002] Heat sink fins, also known as FI N, are classified as "passive heat dissipation components" in the field of electronic engineering design. They are made of metals with good thermal conductivity, light weight, and easy processing (mostly aluminum or copper, silver is too expensive and generally not used) attached to the heat-generating surface to dissipate heat in a composite heat exchange mode. When the tooling fixture is in operation, the FI N is usually assembled in the fixture to dissipate heat for the tooling fixture.

[0003] Since the tolerance of the heat dissipation product assembly parts (FIN) is +0 / -1, in order to better pick up the product, the length of the base fixture will be greater than the maximum tolerance of the product by 0.1mm. If the FI N has a negative tolerance, the length of the base placement groove will be 1.1mm greater than the product itself. The FI N will shake left and right in the placement groove, which is inconvenient to effectively position the FI N, resulting in poor size of the finished product after assembly. Therefore, a work fixture for auxiliary positioning is proposed to articulate the above problem. Utility Model Content

The auxiliary positioning component 6 also includes a connecting groove 64 opened at the front end of the fixture base body 1, and the auxiliary positioning component 6 also includes a cover component arranged on the inner side of the connecting groove 64.

[0024] Among them, the heat sink fin body 2 is located inside the placement slot 3 and plugged into it. The heat sink fin body 2 can be placed in the fixture base body 1 through the placement slot 3. The placement slot 3 is communicated with the taking slot 5, and sufficient space is reserved for taking the heat sink fin body 2, so that the staff can take out the heat sink fin body 2 in the placement slot 3 through the taking slot 5.

[0025] In addition, the placement groove 3 is connected with the positioning groove 61, and the sliding aluminum block 63 is located inside the positioning groove 61 and is slidably connected thereto, so that the sliding aluminum block 63 can slide in the positioning groove 61, thereby enabling the sliding aluminum block 63 to slide in the jig base body 1, and the sliding aluminum block 63 can abut against the heat sink fin body 2, so that the sliding aluminum block 63 can limit the heat sink fin body 2, which can effectively reduce the shaking of the heat sink fin body 2 in the placement groove 3.

[0026] Furthermore, the connecting groove 64 is connected to the positioning groove 61 , and the width of the inner cavity of the connecting groove 64 is smaller than the width of the inner cavity of the positioning groove 61 , so as to prevent the sliding aluminum block 63 from moving into the connecting groove 64 , thereby limiting the moving range of the sliding aluminum block 63 .

[0027] See also Figure 3-4The cover assembly in this embodiment includes two fixing holes 65 opened on the rear wall of the inner cavity of the connecting groove 64, and the cover assembly also includes a cover plate 66 placed in the connecting groove 64, and two connecting holes 67 are opened at the front end of the cover plate 66, and the inner side of the connecting hole 67 is threadedly connected with a fastening screw 68.

[0028] Among them, the cover plate 66 is located inside the positioning groove 61 and the connecting groove 64, and the cover plate 66 and the positioning groove 61 and the connecting groove 64 are all plugged in, so that the cover plate 66 is plugged into the inside of the positioning groove 61 and the connecting groove 64, so that the cover plate 66 can be plugged into the inside of the fixture base body 1, and the sliding aluminum block 63 can be restricted in the positioning groove 61 to prevent the sliding aluminum block 63 from falling out of the positioning groove 61.

[0029] In addition, the fastening screw 68 penetrates into the interior of the communicating hole 67 , and the fastening screw 68 and the communicating hole 67 are threadedly connected, so that the fastening screw 68 can pass through the communicating hole 67 and out of the interior of the cover plate 66 .

The fastening screw 68 can be fixed to the inside of the connecting groove 64 through the fixing hole 65, that is, the fastening screw 68 can pass through the inside of the fixing hole 65 and move to the inside of the connecting hole 67, so that the cover plate 66 can be fixed to the inside of the positioning groove 61 and the connecting groove 64 through the two fastening screws 68.

[0031] The working principle of the above embodiment is:

[0032] When in use, the heat sink fin body 2 needs to be placed in the placement groove 3 of the fixture base body 1. The staff pushes the sliding aluminum block 63 to move the sliding aluminum block 63 into the positioning groove 61. At the same time, the sliding aluminum block 63 squeezes the spring 62, so that the heat sink fin body 2 can be placed in the placement groove 3. When the heat sink fin body 2 is located in the placement groove 3, the spring 62 pushes the sliding aluminum block 63 to move to the left, so that the sliding aluminum block 63 can abut against the heat sink fin body 2, so that the sliding aluminum block 63 can position and limit the heat sink fin body 2, which can reduce the shaking of the heat sink fin body 2 in the placement groove 3. When the sliding aluminum block 63 and the heat sink fin body 2 are After contact, the cover plate 66 can be inserted into the connecting groove 64 and the positioning groove 61, and the fastening screw 68 can be inserted into the connecting hole 67, and the fastening screw 68 can be rotated so that the fastening screw 68 can be moved from the connecting hole 67 into the fixing hole 65, so that the cover plate 66 can be fixedly installed in the connecting groove 64 and the positioning groove 61, and the above steps are repeated to fix another fastening screw 68 in the fixing hole 65, so that the cover plate 66 can be firmly fixed in the connecting groove 64 and the positioning groove 61, so that the sliding aluminum block 63 can be sealed in the positioning groove 61, and the sliding aluminum block 63 can be prevented from falling off from the positioning groove 61, so as to avoid affecting the positioning and limiting property of the sliding aluminum block 63 on the heat sink fin body 2.
