Description

Tapping thread detection device

technical field

The utility model relates to a detection device, in particular to a tapping thread detection device.

Background technique

In machining, in order to achieve positioning and installation of parts with other parts, in-mold tapping machines are generally used to tap parts. After the above-mentioned tapping processing is completed, in order to ensure the quality of the product tapping, the thread of the tapping is generally detected after the tapping is completed. The current detection mainly relies on two types, one is the synchronous detection of the tapping in the mold, that is, After the tapping of the internal tapping machine is completed, the in-mold tapping detection device is used to detect it. This method has fast detection speed and high accuracy. The structure and the requirements for the space in the mold are relatively high, and there are certain limitations in its use. The other is to perform a single inspection manually through a thread gauge. This inspection has low efficiency and slow speed, and there is a certain error rate in manual inspection, so it is difficult to meet the needs of actual production.

Utility model content

The purpose of the utility model is to overcome the shortcomings of the existing technology and provide a tapping thread detection device.

In order to achieve the above purpose, the technical solution adopted by the utility model is: a tapping thread detection device, including a frame, a gantry frame, a lifting cylinder, a detection motor, a movable plate, a mounting plate, a pressing block, and the gantry frame is installed on the machine. On the frame, the lifting cylinder is installed on the gantry frame, the main shaft of the lifting cylinder extends vertically downwards, and a movable plate is installed at the lower end of the main shaft; the movable plate cooperates with the gantry frame through at least two positioning guide rods to realize vertical direction guidance Positioning; the movable plate is installed with several mounting plates through several connecting rods; the detection motor is installed on the mounting plate; the main shaft of the detection motor is equipped with a thread gauge; the mounting plate is also equipped with a pressing block through a guide rod with a spring; the bottom surface of the pressing block There is a rubber layer with a thickness of not less than 4mm; a positioning jig is installed on the frame; the positioning jig is matched with the pressing block.

The utility model is simple in structure and reasonable in design. The detection motor, pressing block and thread gauge can be driven downward by the lifting cylinder. The pressing block first contacts the parts placed on the positioning fixture to press and fix the parts, and then the thread gauge is aligned. Thread detection.
