In order to achieve the above object, the utility model mainly adopts the following technical solutions:

A heat sink automatic rotary milling machine, comprising a base plate (1) and a bracket (3), wherein a rack (9) is installed on the base plate (1), and a turntable (13) is arranged on the rack (9) , the bottom of the turntable (13) is provided with a gear meshing with the rack (9), the top of the turntable (13) is provided with a positioning support (11) for fixing the heat sink, and the outer side is provided with a positioning groove (8).

Wherein the positioning support (11) is provided with a third cylinder (12) and a push plate connected with the third cylinder (12).

Wherein the base plate (1) is also equipped with a positioning fixture (6), a positioning block (4) corresponding to the above-mentioned positioning groove (8) is fixed in the positioning fixture (6), the positioning block (4) and The first cylinder (7) is connected.

Wherein the rack (9) is connected with a second cylinder (10).

Wherein the two sides of the support (3) are provided with a linear track (2), the bottom of the bottom plate (1) is provided with a sliding sleeve (5) corresponding to the linear track (2), and the sliding sleeve (5) is movably fixed on the straight line on track (2).

In the utility model, the heat sink is fixed on the turntable, the top of which is pressed by the push plate controlled by the third cylinder, and the rear end is fixed in the positioning groove by the positioning block connected with the first cylinder. When one side of the heat sink is milled After the cutting is completed, the third cylinder controls the separation of the push plate from the top of the heat sink, the first cylinder controls the separation of the positioning block from the positioning groove of the turntable, and at the same time the second cylinder drives the rack to move, and the rack drives the turntable to rotate to make the heat dissipation The other side of the sheet is rotated to the position of the milling cutter, and then it is fixed, and the other side is milled. Compared with the prior art, the utility model drives the turntable to rotate through the movement of the rack, and realizes the milling treatment of the two sides of the heat sink, which solves the problem that only one side can be milled and cut in the current milling process of the heat sink, and the production efficiency is improved. Not a high question.

Detailed ways

In order to illustrate the idea and purpose of the utility model, the utility model will be further described below in conjunction with the accompanying drawings and specific embodiments.

See also shown in Fig. 1, Fig. 1 is the structural representation of the utility model. The utility model provides an automatic rotary milling machine for both sides of a heat sink, which is used for milling both sides of a heat sink.

The automatic rotary double-sided milling machine includes a bottom plate 1 and a support 3, and the two sides of the support 3 are provided with a linear track 2, and the bottom of the bottom plate 1 is provided with a sliding sleeve 5 corresponding to the linear track 2, and the sliding sleeve 5 is movably fixed on the linear track. 2, the bottom plate 1 can move linearly along the linear track 2 through the sliding sleeve 5.

A rack 9 is installed on the bottom plate 1, one end of the rack 9 is connected with the second cylinder 10, the movement is controlled by the second cylinder 10, and the other end is connected with the adjusting bolt 14 for controlling the moving distance. A turntable 13 is arranged on the rack 9, and the bottom of the turntable 13 is provided with a gear meshed with the rack 9. When the rack 9 moves, the turntable 13 is driven to rotate accordingly.

The top of the turntable 13 is provided with a positioning support 11 for fixing the heat sink, and two symmetrical positioning grooves 8 are provided on the outer side, and the heat sink can be correspondingly stuck on the above-mentioned positioning support 11. The third air cylinder 12 and the push plate connected with the third air cylinder 12 control the movement of the push plate up and down by the third air cylinder 12 to realize the clamping and loosening of the cooling fins.
