Description
Technical Field
[0001] This utility model relates to the field of automotive body sheet metal inspection technology, and in particular to a tooling for inspecting the external dimensions of automotive body sheet metal. Background Technology
[0002] Inspection fixtures are a type of tooling used in the automotive industry to inspect the shape and dimensions of irregular parts (such as plastic parts for interior and exterior car trim, or sheet metal parts for car bodies). Automotive parts need to be inspected during use to ensure safety and record data.
[0003] However, automotive parts have complex structures. When there are simulation blocks or other detection structures around the product, or when the surface to be inspected is restricted by the product's own structure, it is easy to make it impossible to visually inspect or directly use measuring tools such as feeler gauges, thus affecting the inspection results. Therefore, it is necessary to provide a tooling for inspecting the external dimensions of automotive sheet metal to solve the above problems. Utility Model Content
[0004] The main purpose of this utility model is to provide a tooling for inspecting the external dimensions of car body sheet metal, which can effectively solve the problems in the background art.

The limiting pin passes through the T-shaped connector, and the bottom end of the limiting pin contacts the mounting slide rail. A limiting groove is formed in the middle of the top of the mounting slide rail, and the limiting pin is slidably connected inside the limiting groove.
[0008] Preferably, the arc-shaped support base has a sliding groove in the middle, and the sliding groove extends through both sides of the arc-shaped support base. The top of the arc-shaped support base has a through groove in the middle, and the through groove communicates with the sliding groove. An arc-shaped limiting plate is fixedly connected in the middle of the sliding groove, and an adjusting rod is sleeved on the outside of the arc-shaped limiting plate. The adjusting rod is slidably connected inside the sliding groove.

The end of the auxiliary telescopic rod away from the L-shaped adjusting block is rotatably connected to a connecting block, and the connecting block is fixedly connected to one side of the T-shaped connecting seat.
[0012] Compared with the prior art, the present invention has the following beneficial effects: In this invention, an adjusting rod drives an L-shaped adjusting block and an auxiliary telescopic rod to rotate, thereby adjusting the positions of two mounting slide rails and two detection blocks.

The adjusting rod 15 is slidably connected inside the sliding groove 11. A positioning groove is opened at the top of the end of the adjusting rod 15 near the arc-shaped limiting plate 12. A positioning screw 13 is inserted into the positioning groove. The positioning screw 13 is slidably connected inside the through groove 14. A rotating handle is provided at the top of the positioning screw 13. The bottom of the rotating handle at the top of the positioning screw 13 is in contact with the top of the arc-shaped support seat 10.
