Description

Technical Field

[0001] The utility model relates to the technical field of component inspection tools, in particular to a component inspection tool for an automobile chassis module. Background Art

[0002] Most parts are used in the process of automobile manufacturing. After production, the parts will be manually inspected and measured with vernier calipers and go / no-go gauges. When inspecting parts, the form and position tolerances of the parts cannot be detected. At the same time, it is necessary to pay attention to the measuring points of the parts during inspection. During the measurement process, the measurement position may deviate due to different points, resulting in misjudgment.

[0003] When inspecting parts, the caliper needs to be adjusted continuously to carry out the measurement process. The operation time is long and the size of the geometric tolerance cannot be detected, which is prone to misjudgment by personnel and has low inspection efficiency.

[0004] The existing inspection scheme conforms to the design principles and actual usage of parts and components, and can simultaneously inspect multiple form and position tolerance dimensions of parts and components, thereby greatly reducing the inspection time and filling the gap that the original inspection scheme cannot detect form and position tolerance dimensions. At the same time, it can reduce the misjudgment of parts and components due to different operating techniques of personnel. Utility Model Content

[0006] Based on the technical problems existing in the background technology, the utility model proposes an automobile chassis module component inspection fixture, including a panel, wherein support columns are installed on the panel, and there is a gap between any two support columns. Detection pins, positioning pins or clamps are installed on the support columns, and the clamp cooperates with the positioning pin to fix the components, and the root of the detection pin and the root of the positioning pin are spaced apart.

[0007] Preferably, feet are installed below the panel.

[0008] Preferably, the support column is provided with a hole groove, a bushing is installed in the hole groove, and the bushing leaks out of the hole groove.

[0009] Preferably, the detection pin is inserted into the bushing, and the length of the detection pin is greater than the length of the positioning pin.

[0010] Preferably, there are a plurality of positioning pins.

[0011] Preferably, there are a plurality of detection pins.

[0012] Compared with the prior art, the automobile chassis module component inspection fixture proposed by the utility model adopts the above technical solution and achieves the following technical effects:

[0013] The utility model fixes the parts by means of positioning pins and clamps, determines whether the positions of the holes on the parts are standard by means of plugging in detection pins, quickly detects the holes of the parts, and detects the flatness by means of support column detection pin bushings, and can also reduce the misjudgment of the parts caused by different operating techniques of personnel.
