碳纖維方管-纖維方管骨架開口檢具

目前，汽車檢具中應用碳纖維方管復合材料的案例比較多，特別是對前風窗框，車門框，行李箱框等便攜手持式檢具而言，檢具的自重越輕越好，例如，前擋風開口檢具，過去以鋁管骨架加上樹脂模擬塊，這樣一個檢具重量約為30KG，但是由于鋁管的強度有限，一旦使用評率過高，鋁管骨架會產生不同程度的變形，從而導致檢具精度存在偏差，使用碳纖維復合材料制作這種檢具，總重量僅為10-15KG,而且使用壽命長，能有效保證檢具的測試精度，一些大型汽車廠商對于利用碳纖維材料減輕自重這一方面也相當重視，例如上海通用一直積極地對檢具本身的材料進行優化升級，從初的618車型的前后燈樹脂開口檢具，發展到E12全碳素的前后風擋開口檢具，目前正從碳纖維骨架加樹脂模擬塊向全碳纖維一體式檢具發展。

碳纖維復合材料在不同類型的汽車夾具中的應用程度不同，實現的輕量化效果也不同，但實際應用效果還是很令人滿意的，例如，一種碳纖維汽車車燈的檢具，該檢具使用與汽車車燈外形一致的碳纖維本體，該碳纖維本體靠近汽車車燈的一側面上設有定位模塊，剛性定位模塊處設有螺紋套，其中，作為檢具本體的碳纖維材料只需要5mm厚度就可以滿足強度要求，質量輕，變形量小，同時可以模擬整個車燈型面，外觀也比較好。（碳纖維方管）

At present, there are many cases of applying carbon fiber composite materials in automobile inspection tools, especially for portable hand-held inspection tools such as front windshield frames, door frames, and trunk frames. The lighter the weight of the inspection tools, the better, for example, the front Windshield opening inspection tool, aluminum tube frame plus resin simulation block in the past, the weight of such a inspection tool is about 30KG, but due to the limited strength of aluminum tube, once the evaluation rate is too high, the aluminum tube frame will be deformed to varying degrees , Resulting in deviations in the accuracy of the inspection tool. The total weight of this inspection tool is only 10-15KG, and the service life is long. It can effectively ensure the accuracy of the inspection tool. Some large automobile manufacturers are less inclined to use carbon fiber materials. Self-weight is also very important. For example, Shanghai GM has been actively optimizing and upgrading the materials of the inspection tools. From the original 618 model front and rear light resin opening inspection tools to the E12 all-carbon front and rear windshield opening inspection tools, At present, it is developing from a carbon fiber skeleton with a resin simulation block to a full carbon fiber integrated inspection tool.
