Description

Technical Field

[0001] The utility model belongs to the technical field of mechanical processing, and more specifically, particularly relates to a heat sink processing positioning fixture. Background Art

[0002] Heat sinks are key components used to improve heat exchange efficiency and are widely used in electronic equipment, automobile engines, mechanical equipment and other fields. The design of these components is usually aimed at increasing the heat dissipation rate by increasing the surface area, thereby effectively reducing the operating temperature and ensuring the stable operation of the system.

[0003] In the subsequent processing of the heat sink, in order to ensure the processing accuracy and quality and adapt to the special shape of the usage scenario, a clamp is needed to fix the workpiece, and then perform reprocessing such as flushing, grinding and correction on it. The heat sink is distributed in an array of many metal sheets. The traditional clamp fixes the heat sink base, resulting in the metal sheets, which account for a larger proportion, being not stable and easily bent and deformed during grinding, flushing and other processes. The clamping force of the metal sheets cannot be too high, otherwise it is also easy to deform. Slight clamping is unstable and easy to move. Therefore, the traditional clamp fixes the heat sink with insufficient stability and is easy to damage the heat sink.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and a heat sink processing positioning fixture is provided, in order to achieve a purpose with more practical value. Utility Model Content

[0006] The purpose and effect of the heat sink processing positioning fixture of the utility model are achieved by the following specific technical means:

[0007] A heat sink processing positioning fixture comprises a base, L-shaped frames are arranged on both sides of the base, a fixing part is connected to the L-shaped frame through a lifting mechanism, the fixing part comprises a pressure seat, a rotating sleeve is arranged on the rotating sleeve around the pressure seat, a plurality of pressure arms are arranged on the rotating sleeve around the pressure arm, a matching block is connected to the end of the pressure arm, each matching block is provided with a pattern corresponding to the pattern of the end of the heat sink at the bottom, a plurality of positioning holes are arranged on the rotating sleeve, and a hole matching with the positioning hole is arranged on the pressure seat, one of the positioning holes is penetrated by a pin, and the pin is inserted into the hole of the pressure seat.

[0008] Furthermore, both sides of the base are provided with slide grooves, a slider is slidably arranged in the slide groove, the bottom of the L-shaped frame is connected to the slider, a threaded rod is rotatably connected in the slide groove, and the threaded rod passes through the slider and is threadedly connected thereto.

[0009] Furthermore, the lifting mechanism includes a screw rod, a top seat is provided at the top of the L-shaped frame, a screw rod is passed through the top seat, the end of the screw rod is rotatably connected to the bottom of the L-shaped frame, a fixing piece is sleeved on the L-shaped frame, and the fixing piece is threadedly connected to the screw rod.

[0010] Furthermore, a handle is provided at the top of the screw rod, and the handle consists of a rotary cover and a plurality of handles on the surrounding side.

[0011] Furthermore, a support platform is arranged on the base between the two L-shaped frames.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] By lifting and lowering the fixing parts, the heat sink placed on the fixture base is fixed in position by the matching block at the front end of the pressure arm, and the corresponding patterns on the matching block can effectively position the heat sink. At the same time, the heat sink is fixed by applying force from the end of the metal sheet, which is more stable. The setting of the matching block makes it less likely to deform, making it more suitable for later processing. BRIEF DESCRIPTION OF THE DRAWINGS
