Technical Field

It is necessary to check the aperture and the relative position of the fitting fixing hole at the time of shipment.
The traditional method for detecting whether the aperture and the relative position of the fixed hole deviate mainly comprises the step of taking a vernier caliper to measure the aperture of the fixed hole and judging whether the aperture is within positive and negative deviation. Or designing a tool, and installing a locating pin on the tool. The diameter of the locating pin is consistent with the fixed aperture, and the relative position of the locating pin is consistent with the relative position of the accessory fixing hole. Therefore, the fixing hole can be considered to be good as long as the accessory can pass through the locating pin, otherwise, the accessory can not pass through the locating pin, and the aperture of the accessory hole or the relative position of the hole are not right, namely, the accessory is a defective product. However, such an operation must rely on manual work to place the fitting into the tool and require the human eye to see if the fitting properly passes through the locating pin.

In the figure, 2 is a fixed frame, 3 is a pin, 4 is a probe, 5 is an elastic piece, 6 is a conductive metal sheet, 21 is an upper fixing frame, 22 is a lower fixing frame, and 7 is a limiting piece.
Detailed Description
The present invention will be further described with reference to the accompanying drawings and specific examples, which are not intended to limit the invention, so that those skilled in the art may better understand the invention and practice it.
As shown in fig. 1, a switching device for automatically detecting the aperture and position of a fixing hole of the present invention includes a traction mechanism, a fixing frame 2, a pin 3, a probe 4, an elastic member 5, a conductive metal sheet 6, and a pair of probes 4. The traction mechanism is fixedly connected with the fixed frame 2. The fixed frame 2 comprises an upper fixed frame 21 and a lower fixed frame 22 which are oppositely arranged, and the upper fixed frame 21 and the lower fixed frame 22 are oppositely and fixedly connected. The two ends of the pin 3 respectively pass through the upper fixing frame 21 and the lower fixing frame 22, and the pin 3 and the fixing frame 2 can slide relatively. The elastic piece 5 is sleeved on the pin 3, the conductive metal sheet 6 is fixed on the pin 3, the elastic piece 5 and the conductive metal sheet 6 are positioned between the upper fixing frame 21 and the lower fixing frame 22, and the upper end and the lower end of the elastic piece 5 are respectively contacted with the inner surface of the upper fixing frame 21 and the upper surface of the conductive metal sheet 6. The pair of probes 4 are mounted on the inner side of the upper holder 21, and the ends of the probes 4 extend toward the conductive metal sheet 6.
In the initial state, a gap is kept between the pair of probes 4 and the conductive metal sheet 6, and the probes 4 are disconnected. When the fixed frame 2 is forced to slide relative to the pin 3, the upper fixing frame 21 compresses the spring, the ends of the pair of probes 4 come into contact with the conductive metal sheet 6, and the pair of probes 4 are in a closed state.
In the present embodiment, the elastic member 5 is a spring.
The shape and the size of the lower end of the pin 3 are matched with those of the fixing hole to be detected.
Further, a stopper 7 is fixedly provided at the upper end of the pin 3, and the stopper 7 is located outside the upper holder 21.
In this embodiment, the traction mechanism is a cylinder.
The working principle of the switch device for automatically detecting the aperture and the position of the fixed hole is as follows: when the aperture and the relative position are detected, the traction mechanism drives the fixed frame and the positioning pin to move downwards. If the aperture and the position of the measured fixed hole have no deviation, the locating pin passes through the measured fixed hole, and the two probes in the detection mechanism are independent of each other and are equivalent to an open switch. If the aperture of the measured fixing hole is smaller or the position is deviated, the positioning pin cannot pass through the measured fixing hole. As the frame continues to move downward, the springs will be compressed and both probes will be in contact with the conductive metal sheet. At this time, the two probes are connected together through the conductive metal sheet, which corresponds to a closed switch. That is, the switch is in an off state when both the detected fixed-hole aperture and the relative position are normal. When the detected aperture and relative position of the fixed hole are abnormal, the switch is in a conducting state.
When in actual use, the switch structure is matched with an automatic detection controller such as a PLC and the like to realize automatic detection of the positioning state.
The above-described embodiments are merely preferred embodiments for fully explaining the present invention, and the scope of the present invention is not limited thereto. Equivalent substitutions and modifications will occur to those skilled in the art based on the present invention, and are intended to be within the scope of the present invention. The protection scope of the invention is subject to the claims.
