Technical Field
The utility model relates to a novel nut plate assembly thread passing detection tool, and belongs to the field of automobile parts.
Background
With the improvement of the requirement of the automobile industry on the welding quality, the thread passing performance of a welded product containing threads is very critical to the quality of the whole automobile assembly, the thread passing performance is always manually operated by an operator through a thread go-no-go gauge, and the problems of untimely detection, welding defect outflow, low working efficiency and the like are easily caused because the thread passing performance cannot be checked by 100% due to the complexity of the manual operation.
Disclosure of Invention
In order to solve the technical problem, the utility model provides a novel nut plate assembly thread passing detection tool.
The technical scheme adopted by the utility model is as follows: a novel nut plate assembly thread passing detection tool comprises a bottom plate, wherein a positioning tool, a clamping mechanism and a pneumatic device are arranged on the upper end surface of the bottom plate, and the pneumatic device is connected with the clamping mechanism; the pneumatic device uses compressed air as power output, and the air cylinder is connected with the pressing block to clamp after the workpiece is positioned, so that the stability of the workpiece in the positioning of the tool is ensured.
The positioning tool comprises a right-angle rib plate, a U-shaped groove block is fixedly connected to the end face of the right-angle rib plate, the opening of the U-shaped groove block faces upwards, a strong magnet and a positioning pin are arranged on the U-shaped groove block, and the directions of the strong magnet and the positioning pin are the same. The arrangement of the strong magnet and the positioning pin ensures the accuracy of workpiece positioning
The pneumatic device comprises a guide cylinder, the free end of the guide cylinder is connected with the clamping mechanism, and the clamping mechanism is driven to loosen or clamp through the guide cylinder.
The clamping mechanism comprises a connecting plate and a clamping block, the clamping block is fixedly connected to the side face of the connecting plate, the clamping block faces towards the U-shaped groove block, and the connecting plate can slide on the bottom plate.
And the side wall of the U-shaped groove block is fixedly connected with a sensor.
The utility model has the following beneficial effects: the structure is small and exquisite light, can fix a position fast to dismouting and change are nimble convenient.
Drawings
FIG. 1 is a schematic structural view of a novel nut plate assembly thread passing detection tool.
Detailed Description
The utility model provides a novel nut plate assembly screw thread trafficability characteristic detects frock, includes bottom plate 1, and 1 up end of bottom plate is equipped with location frock 2, clamping mechanism and pneumatic means, and pneumatic means is connected with clamping mechanism, and the nut plate that awaits measuring is fixed through location frock 2 location, and pneumatic means drives clamping mechanism and presss from both sides tightly the nut plate that awaits measuring, carries out follow-up detection processes.
