Detailed Description

Referring to fig. 1 to 6, specific structures of a preferred embodiment of the present utility model are shown, which are a copper milling tool.

The wedge-shaped block 25 pushes the two extrusion blocks 23 to move in opposite directions, so that the two copper cooling fins 18 are extruded and fixed on the flange 22, the working efficiency is higher, and fewer accessories are needed. After the copper heat sink 18 is secured, its working surface is fully exposed, without interference problems.

Referring to fig. 1-6, the present application provides a copper milling tool, which includes a base 10, wherein a plurality of positioning mechanisms 20 are arranged on the base 10; the positioning mechanism 20 comprises a material seat 21, a flange 22, an extrusion block 23, a wedge block 25, a spring 26 and a positioning column 15; the two sides of the wedge-shaped block 25 are provided with the extrusion blocks 23; the spring 26 is arranged in a spring hole 28 arranged on the extrusion block 23, and the elastic force of the spring 26 pushes the extrusion block 23; the material seat 21 is arranged beside the extrusion block 23; the first side of the material seat 21 is provided with the flange 22; the second side of the material seat 21 is provided with the positioning column 15; the wedge-shaped block 25 is connected to the output end of the first driving cylinder 27, and the wedge-shaped block 25 pushes the extrusion block 23 to move towards the material seat 21. The number of the positioning mechanisms 20 provided on the base 10 may be set as required, and is not particularly limited. Referring to fig. 3, in this embodiment, eight positioning mechanisms 20 are arranged vertically and horizontally on the base 10. The upper and lower positioning mechanisms 20 share a set of ribs 22. Preferably, the base 10 is a fitting made of stainless steel or aluminum alloy. Preferably, the wedge-shaped block 25 has a trapezoidal vertical section, a small lower end and a large upper end. The material seat 21 protrudes from the base 10.

The positioning mechanism 20 works on the principle: the copper cooling fin 18 is placed on the material seat 21, and the first driving cylinder 27 drives the wedge block 25 to move downwards. The side of the wedge-shaped block 25 pushes the extrusion block 23, the extrusion block 23 extrudes the copper cooling fins 18 on the material seat 21, and then the copper cooling fins 18 are blocked by the blocking edge 22, so that the fixation is completed. The wedge-shaped block 25 is lifted and reset, the elastic force of the spring 26 enables the extrusion block 23 to loosen the copper cooling fin 18, and the copper cooling fin 18 can be easily taken out, so that convenience is brought. Since the pressing block 23 presses the side edge of the copper heat sink 18, the processed surface of the copper heat sink 18 is completely exposed, and thus there is no problem of processing interference. In addition, when wedge 25 moves down, can fix two copper fin 18 simultaneously, efficiency is higher, and required accessory and cylinder also can be less, and frock cost is also lower. The positioning column 15, the flange 22 and the extrusion block 23 are matched together, namely, the three edges are fixed, so that the positioning of the copper radiating fin 18 is facilitated, and the deviation is avoided. The positioning post 15 and the wedge block 25 are moved synchronously.

Preferably, both sides of the extrusion block 23 are provided with sliding grooves 24; a plurality of mounting grooves 11 are formed in the base 10, and sliding blocks 12 are protruded from the inner walls of the mounting grooves 11; the slider 12 slides back and forth in the chute 24. This design is advantageous in controlling the movement locus of the extrusion block 23 and preventing it from deviating.

Preferably, the positioning column 15 is arranged on the connecting rod 17, and the second cylinder 16 drives the connecting rod 17 to move up and down so that the connecting rod 17 extends or retracts in the base 10. The second cylinder 16 drives a plurality of positioning columns 15 through connecting rods 17 at the same time, so that the requirement of the cylinder is further reduced.

Referring to fig. 1, preferably, a first notch 29 is disposed on a side of the flange 22 near the material seat 21; the material seat 21 is provided with a second notch 21; the first notch 29 and the second notch 21 are opposite. After the CNC equipment processing of the copper cooling fin 18 is finished, the extrusion block 23 is pushed by the elastic force of the spring 26, so that the second notch 21 is exposed, and the clamp of the manipulator can take out the copper cooling fin 18 from the positions of the first notch 29 and the second notch 21, so that the CNC equipment processing is more convenient.

Preferably, the pressing block 23 has a slope adapted to the outer surface of the wedge block 25. The wedge 25 has a trapezoidal vertical cross section. The inclined surface of the extrusion block 23 is pushed by the downward movement of the wedge block 25, so that the extrusion block 23 moves toward the copper heat sink 18 to complete the fixation.

Referring to fig. 1, preferably, a supporting leg 13 is disposed at the bottom of the base 10, and a locking hole 14 is disposed on the supporting leg 13. The four supporting feet 13 are distributed on the four corners of the bottom of the base 10. The lock hole 14 is used for locking the base 10, so that the base 10 is convenient to disassemble, and the time for replacing and disassembling the equipment is reduced.

In summary, the key point of the design of the present utility model is that when the wedge-shaped block 25 moves downward, the two extrusion blocks 23 can be pushed to move in opposite directions, so that the two copper cooling fins 18 are extruded and fixed on the flange 22, which improves the working efficiency and requires fewer accessories for fixing the copper cooling fins 18. The copper fins 18 are fixed from the side of the copper fins, and the processed surface of the copper fins is completely exposed, without interference.
