Description

Technical Field

[0001] This utility model belongs to the field of heat sink processing tooling technology, specifically relating to a positioning and locking tooling for processing irregularly shaped heat sinks. Background Technology

[0002] When manufacturing heat sinks, due to their complexity, the need for positioning and locking, and considerations for their lifespan and strength, the initial heat sinks produced are only blanks. Their internal structure needs to be processed. These heat sinks are products where only the external structure is in place; the internal mounting structure requires further machining. If the internal mounting structure is formed using a casting process, the casting mold is too complex, resulting in high costs for both the mold and the individual heat sink. If the internal mounting structure is machined in a secondary process, the process is simpler and has a wider range of machine tool compatibility.

[0003] Currently, the processing of irregularly shaped heat sinks is done using bench vises. However, bench vises can only hold and process one irregularly shaped heat sink at a time, resulting in low work efficiency. Without the aid of tools, the process relies solely on experience, which is not very operable. Furthermore, when clamping and processing a single irregularly shaped heat sink, people often cut their fingers due to burrs, affecting production efficiency. Therefore, we propose a positioning and locking fixture for processing irregularly shaped heat sinks. Utility Model Content

[0004] The purpose of this invention is to provide a positioning and locking fixture for processing irregularly shaped heat sinks, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a positioning and locking fixture for machining irregularly shaped heat sinks, comprising:

[0006] A tooling base plate, which is mounted on a machine tool;

[0007] Two side baffles are provided, and the two side baffles are symmetrically arranged on both sides of the upper end of the tooling base plate;

[0008] The positioning block is provided on the tooling base plate;

[0009] A positioning slot for placing several irregularly shaped heat sinks is formed between the tooling base plate, the side baffle plate and the positioning block;

[0010] The outermost irregular heat sink block is provided with a locking bolt that connects to the tooling base plate.

[0011] Preferably, the tooling base plate has a placement groove, and several irregularly shaped heat dissipation blocks are arranged and placed in the placement groove, and are limited and locked by the side baffle plate, the positioning block and the locking bolt.

[0012] Preferably, the side retaining plate has several equally spaced opening slots, and the side retaining plate is set at the upper side of the tooling base plate through the opening slots and fastening bolts.

[0013] Preferably, the inner side of the side baffle plate extends toward the placement groove on the tooling base plate.

[0014] Preferably, the positioning slot is a T-shaped slot.

[0015] Preferably, a processing avoidance hole is provided in the placement groove corresponding to the square or round hole to be processed on the irregular heat sink.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] This utility model includes a tooling base plate, side retaining plates, positioning blocks, positioning slots, and locking bolts. In use, the tooling base plate is fixed to a machine tool, and the two side retaining plates are positioned on the upper sides of the tooling base plate via openings and fastening bolts. This creates a T-shaped positioning slot between the tooling base plate, side retaining plates, and positioning blocks, for placing several irregularly shaped heat sinks. Several irregularly shaped heat sinks are then pushed into the positioning slot in sequence, and locking bolts are screwed into the side of the outermost irregularly shaped heat sink, thus locking and fixing the heat sinks in the positioning slot. The machine tool then processes the heat sinks sequentially. Disassembly only requires removing one locking bolt to remove the processed heat sink. This enables batch production of irregularly shaped heat sinks, improving production efficiency, reducing production costs, minimizing human intervention, improving the consistency of processing quality, enhancing the processing quality of the heat sinks, and reducing the labor intensity and workload of operators on the production line.
