Description

Technical Field

[0001] This utility model relates to the field of testing equipment technology, specifically to a tooling for testing the thickness of precision structural parts. Background Technology

[0002] A heat spreader is a device used to dissipate heat from easily heated electronic components in electrical appliances. They are mostly made of aluminum alloy, brass, or bronze and can be in the form of plates, sheets, or multiple sheets. For example, the CPU central processing unit in a computer requires a fairly large heat spreader, and the power transistors, horizontal output transistors, and power amplifier transistors in a television all use heat spreaders.

[0003] The installation dimensions of heat spreaders in electrical appliances are not consistent across different appliances. Existing heat spreader manufacturers need to design a special testing fixture to measure the thickness of each heat spreader product with different specifications. The thickness of the product tested by the designed testing fixture is fixed, and it can only be used to test the thickness of the specific product. It cannot test heat spreaders of other sizes and thicknesses, resulting in poor versatility, increased production costs, and waste of resources.

[0004] A patent with publication number CN213579050U is disclosed in the prior art. The solution includes a base, which is provided with a clamping mechanism and a detection mechanism. The detection mechanism includes a first test plate and a second test plate arranged opposite to each other. The first test plate is fixedly connected to the base, and the second test plate is slidably connected to the base. A first adjusting rod is rotatably connected to the side of the second test plate facing the first test plate. The first adjusting rod is screwed to the first test plate, which improves the versatility of the heat sink thickness detection device.

[0005] With use, existing devices, including those mentioned above, have gradually revealed shortcomings in this technology, mainly in the following aspects:

[0006] First, the current manual measurement using calipers poses a risk of defective products leaking out, leading to customer complaints.

[0007] Secondly, using calipers to measure products involves hard contact, which poses a risk of scratching the product and is inefficient, wasting manpower.

[0008] Third, the flatness control of the support surface in contact between the product and the tooling is poor. If surface support is used, there is a problem of the product tilting up, and the measured height value is significantly different from the actual thickness value of the product.

[0009] As can be seen from the above, the existing technology obviously has inconveniences and defects in practical use, so it is necessary to improve it. Utility Model Content

[0010] To address the shortcomings of existing technologies, this utility model provides a precision structural component thickness detection fixture. This fixture solves the problems of hard contact in traditional caliper measurements, which poses a risk of scratching the product and is inefficient and wastes manpower. It also addresses the issue of poor flatness control of the support surface in contact between the product and the fixture, which can cause the product to warp if surface support is used, resulting in a significant discrepancy between the measured height and the actual thickness.

[0011] To achieve the above objectives, the present invention provides the following technical solution.

[0012] A precision structural component thickness inspection fixture includes a fixture plate, a positioning baffle fixed to the upper surface of the fixture plate, positioning holes matching the shape of the product on the positioning baffle, and raised support portions at the four corners of the fixture plate near the positioning holes.

[0013] As an optimized solution, the height of the protruding support is higher than the upper surface of the tooling plate.

[0014] As an optimized solution, the positioning baffle has an operating hole that communicates with one of the opposite edges of the positioning hole.

[0015] As an optimized solution, the upper surface of the tooling plate is provided with an operating groove that is aligned with the operating hole.

[0016] As an optimized solution, the upper surface of the protruding support is a reference plane.

[0017] As an optimized solution, arc-shaped clearance channels are provided at the four corners of the positioning hole.

[0018] As an optimized solution, the positioning holes are arranged in a matrix of four evenly distributed holes.

[0019] As an optimized solution, the positioning baffle is provided with screw holes, and the positioning baffle is fixed to the tooling plate by screws.

[0020] Compared with the prior art, the beneficial effects of this utility model are:

[0021] The heat spreader is supported by a tooling plate and a positioning baffle, eliminating the risk of misjudgment caused by human factors; and avoiding the risk of scratching the product due to direct contact with the testing instrument.

[0022] The tooling plate has raised support parts at the four corners near the positioning holes, which supports the heat spreader at the four corners and overcomes the problem of poor flatness control of the support surface where the product contacts the tooling. Attached Figure Description
