Description

Technical Field

[0001] The utility model relates to the technical field of body-in-white measurement, in particular to a body-in-white detection bracket. Background Art

[0002] In the production of the body-in-white, in order to ensure the accuracy of each component and the overall coordination of the body-in-white, the body-in-white needs to be inspected. During the inspection of the body-in-white, the inspection bracket is required to support and position the body-in-white. The inspection bracket needs to be adjusted in the three directions of horizontal, longitudinal and vertical directions to accurately position and support the body-in-white.

[0003] The disclosed technical solution named "body-in-white detection bracket" (document number CN 205246026 U) is shown in the figure, including a positioning mechanism 10, a three-dimensional adjustment device 20, a base 30 and a fixing device 40. By setting a first adjustment block 21, a second adjustment block 22, an adjustment gasket 23 and a fixing device 40 in the three-dimensional adjustment device 20, the position in each direction can be changed by changing the thickness of the adjustment gasket 23 in each direction, and then the body-in-white detection bracket is adjusted in three directions. In this document, the position of the bracket itself on the detection platform does not change, and the bracket is adjusted in three directions only by placing gaskets 23 of different thicknesses in the adjustment device 20 on the bracket, resulting in a small adjustment range of the bracket in three directions and the bracket position cannot be adjusted steplessly by using gaskets.

[0004] The disclosed technical solution named "Universal BIW Inspection Platform" (document number CN 201837523 U) is shown in the figure, including a platform base 1, a bottom plate 2, and a bracket. The bottom plate 2 is fixedly connected to the platform base 1. A preset bracket mounting hole 10 is arranged on the bottom plate 2. The bracket is fixedly connected to the bottom plate 2 through the bracket mounting hole 10, and a flipping mechanism is provided on the bracket. During the inspection, the positioning frame on the bracket that is not in use is turned over, and the positioning frame that needs to be used is erected and locked with a positioning pin. In this document, when inspecting the same body, the positioning frame on the bracket that needs to be used is erected through the flipping mechanism provided on the bracket, and the positioning frame on the bracket that is not in use is turned over. Therefore, for each additional body that needs to be inspected, a corresponding set of inspection brackets needs to be installed on the inspection platform. Utility Model Content

[0005] The utility model aims to provide a body-in-white detection bracket.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A body-in-white inspection bracket has a vertically arranged rod seat on the base, characterized in that the rod seat is connected to a tube seat above it by a screw nut mechanism, a positioning pin is provided at the upper end of the tube seat, and a switch-type magnet is arranged on the base.

[0008] In the above scheme, the bracket base can be fixed on the bottom plate of the detection platform through the adsorption effect of the switch-type magnet. When the switch-type magnet is turned off, the adsorption effect is lost, and the bracket can be moved on the bottom plate of the platform at will, which is convenient for the bracket to move to a specified position in the horizontal direction. When the position of the bracket on the bottom plate is fixed, the screw nut mechanism on the bracket drives the replaceable positioning pin on the upper end of the bracket to move up and down, so as to complete the adjustment of the bracket in the vertical direction.

The bracket base 10 can be fixed on the bottom plate of the inspection platform through the adsorption effect of the switch-type magnet 12. When the switch-type magnet 12 is turned off, the adsorption effect is lost, and the bracket can be moved on the bottom plate of the platform at will, which is convenient for adjusting the bracket to a specified position in the horizontal and vertical directions. When the position of the bracket on the bottom plate is fixed, the replaceable positioning pin 30 at the upper end of the bracket is driven up and down by the screw nut mechanism on the bracket to complete the adjustment of the bracket in the vertical direction.

[0013] Preferably, the base 10 is disc-shaped, and the lower end of the tubular rod seat 11 is fixedly connected to the middle of the base 10, which ensures the stability of the bracket base and facilitates the switch type magnet 12.
