Description

Technical Field

[0001] The invention relates to a device for detecting the depth of an irregular grooved part, belonging to the technical field of detection and measurement. Background Art

[0002] The airtight belt groove of the aircraft cabin is an irregular groove-shaped part with margins on both sides of the groove. After repair, the depth of the groove is required to be no less than 12 mm, and the value is a key characteristic indicator. This size must be guaranteed during actual processing and final inspection, and the minimum depth must be recorded. At present, visual measurement is performed with a steel ruler. Due to the R angle in the groove, the measurement with a steel ruler is inaccurate, and the human factor has a greater impact. The circumference of the airtight belt groove is about 5 meters. To complete the measurement of the depth on both sides of the groove, it is necessary to use a steel ruler to measure the depth of each position in turn, which is very inefficient. At the same time, this measurement needs to record the minimum value of the groove depth. It is difficult to determine the position of the minimum depth visually, and the measurement effect is not ideal. In order to improve the detection accuracy and efficiency, the present invention designs a depth detection device that can effectively measure the depth of both sides of the airtight belt groove and record the minimum value. Summary of the invention

[0003] In order to solve the above technical problems, the present invention provides a device for detecting the depth of irregular grooved parts.

[0004] The technical solution of the present invention is as follows:

[0005] The device for detecting the depth of an irregular groove-shaped part comprises an upper shell, a screw, a switch, a charging module, a bottom cover, a button, a display screen, a top cover, a sensor, a top screw, a roller, an adapter, a pillar, a slider, a lower shell, a lighting lamp and a nut.

[0006] The upper shell, lower shell, top cover, pillar, slider and bottom cover are the main structural parts of the device, forming a structure similar to the shape of a flashlight. The upper shell, lower shell and bottom cover are made of resin material using 3D printing technology and connected with screws. The top cover, pillar and slider are made of aluminum alloy, with external threads at both ends of the pillar, and internal threaded holes on the top cover and slider. The three are connected together by threaded connection. In order to avoid misjudgment caused by errors in the operation of handheld tools, the height of the slider is designed to be 12mm, and analog detection means are used to assist in judgment. The top cover is connected to the upper shell and the lower shell with screws. The slot on the bottom cover is used to fix the switch and the charging module

[0007] The sensor, top screw, roller and adapter are dual sensing structures of the device. The screw of the sensor housing extends from the hole on the top cover and is fixed with a nut. The shaft on the roller is threaded into the adapter, and the adapter and the sensor rod hole shaft clearance match. After adjusting the height of the adapter, tighten the top screw to fix the adapter and the sensor rod, so that the roller, adapter and sensor rod become a whole. When in use, the roller contacts the edge of the groove part, and the sensor rod performs telescopic movement as the groove depth changes. The internal components of the sensor automatically calculate the groove depth of the groove part according to the compression amount.

[0008] The display screen, button, switch, charging module, and lighting lamp are the data display and integrated circuit system of the device. The display screen is an external component and also a data processing unit. The wiring harness of the button, switch, charging module, lighting lamp and sensor are integrated on the data processing unit. The display screen has three columns, which can simultaneously display the real-time value of the groove depth on both sides and any fixed value that needs to be recorded. The button is bonded in the sunken hole of the upper shell, and pressing it can realize the function of recording any fixed value. The switch and charging module are fixed on the card slot of the bottom cover, wherein the switch control circuit is turned on and off, one end of the charging module is connected to a rechargeable battery, and the other end can be connected to a data cable to charge the battery. There are two lighting lamps in total, which are fixed inside by the card slots in the upper shell and the lower shell. There is a hole for the irradiation passage on the top cover. The lighting and extinguishing are related to the value displayed on the display. When the displayed value is greater than 12mm, it will automatically light up, and when it is less than 12mm, it will automatically extinguish. In this way, it plays a lighting and prompting role.

[0009] The beneficial effects of the present invention are as follows:

[0010] The device for detecting the depth of irregular groove parts of the present invention is simple and convenient to operate, can measure the groove depth in real time and continuously, avoids the local measurement error caused by the number of points selected by the intermittent measurement of the steel ruler, and improves the measurement accuracy. The detection device can measure the depth of both sides of the groove at the same time, and the detection efficiency is greatly improved. BRIEF DESCRIPTION OF THE DRAWINGS
