Description

Technical Field

[0001] This utility model relates to the field of automotive parts testing technology, and in particular to a testing fixture for a liftable and movable automotive tailgate trim assembly. Background Technology

[0002] As automobiles become our primary mode of transportation, the demands on their manufacturing processes have also increased, leading to higher requirements for the quality and inspection of various parts. The dimensions of all parts must be guaranteed to be within permissible tolerances, as this precision directly affects vehicle performance and the assembly of other components. Currently, some large enterprises use coordinate measuring machines (CMMs) to inspect automotive lighting trim parts. The high precision and intelligence of this inspection tool have led to its widespread use. However, CMMs are expensive, require highly skilled operators, and are time-consuming to inspect parts, which does not meet actual production needs.

[0003] Currently, existing technology (CN 209840877 U) discloses a testing fixture for automotive lamp trim parts, which includes: a worktable with at least one testing station; the testing station includes: a positioning group disposed on the worktable; a clamping group disposed on the worktable for fixing the automotive lamp trim part to the positioning group; and a contouring group matching the automotive lamp trim part disposed on the worktable and surrounding the automotive lamp trim part, so that a testing area is formed between the contouring group and the automotive lamp trim part. This utility model has a simple structure and can quickly test whether the dimensions of automotive lamp trim parts conform to the tolerance range of the drawings, improving testing efficiency and reducing testing costs.

[0004] Using the above method, the height of the testing fixture is fixed and cannot be adjusted according to the height of the staff and the way it is used. This requires the staff to bend over to operate, which increases the workload of the staff, reduces the work efficiency, and requires multiple staff to move the testing fixture. Utility Model Content

[0005] The purpose of this utility model is to provide a lifting and moving automotive tailgate trim assembly inspection fixture, which aims to solve the problem that the height of existing inspection fixtures is fixed and cannot be adjusted according to the height of the operator and the usage method.

[0006] To achieve the above objectives, this utility model provides a lifting and moving automotive tailgate trim assembly inspection fixture, including a worktable, an inspection fixture body and an adjustment mechanism. The adjustment mechanism includes a motor, a rotating shaft, transmission gears, two racks, two driven gears, two lifting components and a moving plate.

[0007] The motor is fixedly connected to the worktable and located inside the worktable. The rotating shaft is fixedly connected to the output end of the motor. The transmission gear is fixedly connected to the rotating shaft and located on the side of the rotating shaft away from the motor. The two racks respectively mesh with the transmission gear and are slidably connected to the worktable. The two driven gears respectively mesh with the two racks and are rotatably connected to the worktable. The two lifting components are respectively mounted on the two driven gears. The moving plate is mounted on the two lifting components. The detection fixture body is mounted on the moving plate.

[0008] The lifting assembly includes a screw, a sleeve, and a movable cylinder. The screw is fixedly connected to the driven tooth and is located on the driven tooth. The sleeve is threadedly connected to the screw and is located around the screw. The movable cylinder is fixedly connected to the sleeve and is also fixedly connected to the movable plate.

[0009] The lifting assembly further includes a guide rail and a guide block. The guide rail is fixedly connected to the worktable and located inside the worktable. The guide block is slidably connected to the guide rail and fixedly connected to the moving cylinder, and located between the guide rail and the moving cylinder.

[0010] The adjustment mechanism further includes two opening and closing plates and two handles. The two opening and closing plates are rotatably connected to the worktable and are located on the worktable. The two handles are fixedly connected to the two opening and closing plates and are located on the two opening and closing plates respectively.

[0011] The adjustment mechanism further includes multiple mounting brackets, multiple casters, and multiple brake pads. The multiple mounting brackets are fixedly connected to the worktable and are all located at the bottom of the worktable. The multiple casters are respectively mounted on the multiple mounting brackets, and the multiple brake pads are respectively mounted on the side of the multiple mounting brackets near the casters.

[0012] This utility model discloses a lifting and movable inspection fixture for automotive tailgate trim assemblies. The worktable provides installation conditions for the adjustment mechanism. The inspection fixture body can inspect automotive tailgate trim assemblies. When the inspection fixture body needs to be adjusted, the motor is started, which drives the rotating shaft to rotate. The rotating shaft drives the transmission gear to rotate, which drives two racks to move. The two racks drive two driven gears to rotate, which in turn drive two lifting components to move. The two lifting components move the inspection fixture body on the moving plate away from the worktable until the inspection fixture body is adjusted to a preset position. This completes the adjustment of the inspection fixture body, thus solving the problem that the height of existing inspection fixtures is fixed and cannot be adjusted according to the height of the operator and the usage method.
