Description

Technical Field

[0001] This utility model relates to the field of lightweight aluminum automotive parts manufacturing, specifically a multifunctional measuring tool for lightweight aluminum automotive parts manufacturing. Background Technology

[0002] With the increasing proportion of new energy vehicles, major domestic automakers have begun to adopt lightweight aluminum components to reduce vehicle weight and increase mileage. However, some major reinforcing brackets in new energy vehicles often have bevels or multiple angled bevels, and traditional inspection methods cannot detect the length of these bevels. To inspect the length of a bevel, it is necessary to first measure the bevel angle using an angle gauge or R-gauge, then compare the angle with 3D data to see if they match, and finally measure the minimum and maximum distances from the bevel to the reference edge, comparing the lengths with the 3D data to see if they match.

[0003] This method of measuring bevels is cumbersome and prone to errors. If the bevel angle or length is incorrect during the welding stage, it can cause significant losses to production and the entire project. Developing dedicated inspection fixtures for specific parts is not only extremely costly, but also time-consuming and labor-intensive to maintain, and they are also easily damaged during transportation.

A protractor assembly for measuring the bevel angle of a workpiece is provided on the horizontal bar of the inverted L-shaped ruler, and the protractor assembly can move and lock along the length direction of the horizontal bar.

[0006] Furthermore, the starting point of the scale markings on the crossbar and the starting point of the scale markings on the vertical bar are both located at the intersection of the inner side of the crossbar and the inner side of the vertical bar.

[0007] Furthermore, the length of the crossbar is greater than the length of the longitudinal bar.

[0025] To make the above-mentioned features and advantages of this utility model more easily understood, specific embodiments are described below in conjunction with the accompanying drawings, but this utility model is not limited thereto.

[0026] refer to Figures 1 to 5

[0027] A multifunctional measuring tool includes an inverted L-shaped ruler 10, wherein the horizontal bar 11 and the vertical bar 12 of the inverted L-shaped ruler form a 90° angle, and both the horizontal bar and the vertical bar are provided with scale markings along their respective length directions, thereby being used to measure the length and width of a beveled part 1. A protractor assembly 20 for measuring the bevel angle of the workpiece is provided on the horizontal bar of the inverted L-shaped ruler. The protractor assembly can move and lock along the length direction of the horizontal bar to measure the bevel angle data of the beveled part.

[0028] In this embodiment, in order to ensure the accuracy of the measurement data in the length and width directions, the starting point of the scale markings on the crossbar (the location of the zero scale line) and the starting point of the scale markings on the vertical bar (the location of the zero scale line) are both at the intersection of the inner side of the crossbar and the inner side of the vertical bar 13.

[0029] In this embodiment, the length of the horizontal bar is greater than the length of the vertical bar, so that the length of the beveled part can be measured by the horizontal bar and the width of the beveled part can be measured by the vertical bar.

[0030] In this embodiment, to achieve lightweight design, the inverted L-shaped ruler is made of aluminum plate. Specifically, an aluminum plate with a length of 500mm, a width of 100mm, and a thickness of 30mm (the dimensions can be freely adjusted according to the length of the beveled product, and it needs to be longer than the beveled product) can be used as the raw material to make the inverted L-shape, and the side to be used is milled flat.

[0031] In this embodiment, the protractor assembly includes a slider 21, the rear of which slides with a crossbar and is provided with a locking structure, and a semi-circular protractor 22 is fixed to the front end of the slider. The protractor is provided with angle markings laser-engraved using a laser marking machine.

[0032] In this embodiment, the upper end face of the crossbar is provided with a horizontal groove 111, the bottom surface of the slider is provided with a clamping opening 211, the protrusion 212 located on the rear side of the clamping opening is embedded in the horizontal groove, and a locking bolt 23 that is screwed to the slider is longitudinally provided on the protractor. The rear end of the locking bolt is inserted into the clamping opening to abut against the front end face of the crossbar. The tightness of the clamping opening is adjusted by the locking bolt so as to lock and release the protractor assembly.

[0033] In this embodiment, the zero mark of the angle indicator on the protractor is flush with the bottom surface of the horizontal bar.

[0034] In this embodiment, to achieve lightweight design, both the slider and the protractor are made of aluminum. Specifically, the protractor is made of an aluminum block machined into a 180° semicircular plate by CNC machining, with the semicircular plate being 3.0 mm thick. Angle markings are then engraved on the protractor using a laser marking machine.

[0035] In this embodiment, the upper surfaces of the crossbar and the longitudinal bar are flush and milled flat, and the inner surfaces of the longitudinal bar and the crossbar (the surfaces that mate with the beveled parts) are also milled flat.

[0036] During operation, place the beveled end of the beveled part at the starting point of the scale marking on the horizontal bar of the multi-functional measuring tool. With the beveled part horizontal in the length direction, observe the scale to determine the length data of the beveled part. Then loosen the locking screw so that the protractor can be quickly moved horizontally to the bevel position to measure whether the angle data is correct.

[0037] If this utility model discloses or relates to mutually fixedly connected parts or structural components, then unless otherwise stated, a fixed connection can be understood as: a detachable fixed connection (e.g., using bolts or screws) or a non-detachable fixed connection (e.g., riveting or welding). Of course, mutually fixed connections can also be replaced by an integral structure (e.g., manufactured using a casting process) (except where it is obviously impossible to use an integral forming process).

[0038] In addition, unless otherwise stated, the terms used to indicate positional relationships or shapes in any of the technical solutions disclosed in this utility model above include states or shapes that are similar to, close to, or approximate with them.

[0039] Any component provided by this utility model can be assembled from multiple individual components, or it can be a single component manufactured by a one-piece molding process.

[0040] The above description is only a preferred embodiment of the present utility model. All equivalent changes and modifications made within the scope of the patent application of the present utility model shall be covered by the present utility model.
