Description

Technical Field

[0001] The utility model relates to an automobile enclosure panel assembly inspection tool. Background Art

[0002] The automobile guard panel assembly is an important component that constitutes the automobile body structure and plays a connecting and protective role. In order to adapt to the direction of the body structure, the shape of the automobile guard panel assembly is irregular, and the automobile guard panel assembly is assembled from multiple parts. Since the automobile guard panel assembly also needs to have functions such as sound insulation, heat insulation and wiring, the structure is complex and multiple cards and locating pins are installed at the same time. In order to ensure the contour and dimensional accuracy of the automobile guard panel assembly and the position accuracy of each card and locating pin, the assembled automobile guard panel assembly must be inspected with the help of a matching inspection fixture. The inspection fixture is a matching fixture used by industrial manufacturers to fix various workpieces in order to accurately detect the workpiece size.

[0003] However, the existing inspection fixtures for automobile fender assemblies cannot simultaneously inspect the contour and dimensional accuracy of the automobile fender assembly and each locating pin and card. Instead, two sets of inspection fixtures need to be made and carried out in two steps, namely, the automobile fender assembly is first placed and fixed on one of the inspection fixtures to inspect its contour and dimensional accuracy, and then the automobile fender assembly is removed and fixed on another inspection fixture to inspect the position accuracy of each card and locating pin. This results in the need to fix and remove the automobile fender assembly twice, which is time-consuming and labor-intensive, resulting in low inspection efficiency. In addition, the need to make two sets of inspection fixtures will lead to an increase in inspection costs, which needs to be further improved. Utility Model Content

[0042] Working principle:

[0043] The crank handles of the first pull rope mechanism 225, the second pull rope mechanism 234 and the third pull rope mechanism 265 are pushed to drive the two clamping blocks of each first two-way buckle mechanism 223 and the two clamping blocks of each second two-way buckle mechanism 232 to separate from each other through the corresponding brake lines, and at the same time drive the pressure plate of each one-way buckle mechanism 264 to swing downward; the two-way buckle mechanism, the one-way buckle mechanism and the pull rope mechanism are all standard parts used in the field of automobile inspection fixtures, and their structures and the principle that the pull rope mechanism is connected to the two-way buckle mechanism or the one-way buckle mechanism through the brake line to play a driving role are all existing technologies.

[0044] Next, the swinging end of the first vertical flipping mechanism 242 and the swinging end of the second vertical flipping mechanism 252 in each clamping unit in the clamping assembly 24 are rotated forward, thereby respectively driving the first pressure strip 243, the second pressure strip 244, the third pressure strip 245 and the corner pressure block 253 to swing forward; the vertical flipping mechanism is a standard part used in the field of automobile inspection fixtures, and its structure and use method are both existing technologies.

[0045] Next, the automobile guard panel assembly is placed vertically in front of the positioning area 3, and the upper edge of the rear side of the automobile guard panel assembly is fitted on the arc support bar 221, the slope support bar 261 and the arc support wall 231, and the edge of the lower left corner of the rear side of the automobile guard panel assembly is fitted on the corner support wall 29 and the corner limit block 212, and the limit column 2122 on the corner limit block 212 is inserted into the corresponding structural hole in the automobile guard panel assembly; at the same time, each card located on the rear side of the automobile guard panel assembly is inserted into the limit slot 281 on a corresponding seat block 28.

[0046] Subsequently, the swinging end of each first vertical flipping mechanism 242 and the swinging end of the second vertical flipping mechanism 252 are rotated backward to drive the first pressure strip 243, the second pressure strip 244, the third pressure strip 245 and the corner pressure block 253 to swing backward in the same way, until the first pressure strip 243, the second pressure strip 244, the third pressure strip 245 and the corner pressure block 253 are all pressed against the lower front edge of the automobile guard panel assembly, thereby completing the fixation of the automobile guard panel assembly.

[0047] At this time, each positioning pin located at the rear edge of the automobile enclosure assembly extends into the two clamping blocks in the corresponding first two-way buckle mechanism 223 or between the two clamping blocks of the corresponding second two-way buckle mechanism 232; each concave cavity located at the rear edge of the automobile enclosure is located behind the pressure plate of the corresponding one-way buckle mechanism 264; thereafter, the first pull rope mechanism 225, the second pull rope mechanism 234 and the third pull rope mechanism 265 crank handle are pulled in turn to drive the two clamping blocks of each first two-way buckle mechanism 223 and the two clamping blocks of each second two-way buckle mechanism 232 to move closer to each other through the corresponding brake line, and at the same time drive the pressure plate of each one-way buckle mechanism 264 to swing backward; thereby, the two clamping blocks of each first two-way buckle mechanism 223 clamp a corresponding positioning pin, and the two clamping blocks of each second two-way buckle mechanism 232 clamp a corresponding buckle sheet, and the pressure plate of each one-way buckle mechanism 264 is pressed backward in a corresponding concave cavity, so that the precise positioning of the automobile enclosure assembly is completed.

[0048] Before fixing the automobile guard panel assembly, each detection pin 214 needs to be removed. After the automobile guard panel assembly is fixed, each detection seat 213 extends into the groove located at the lower edge of the rear side of the automobile guard panel assembly. Finally, each detection pin 214 is used to pass downward through the reserved hole located at the corresponding position on the automobile guard panel assembly and inserted into a corresponding detection seat 213 to align the hole position. After that, the matching detection measuring tool can be used to detect the structure and size of the automobile guard panel assembly.

[0049] The utility model can simultaneously detect the contour and dimensional accuracy of the automobile enclosure assembly and the position accuracy of each card and positioning pin, without the need to make two sets of inspection fixtures or to divide the inspection process into two steps, thereby simplifying the inspection process to achieve the effect of saving time and labor, improving the inspection efficiency, and reducing the inspection cost.
