[0019] The present invention will be further explained below with reference to the accompanying drawings and specific embodiments.
[0020] Example: As shown in the figure, the micro-hole endoscopic inspection fixture of this utility model includes a working platform 1. A fixture mounting base 2 is bolted to the middle of the working platform 1. A contour fixture 3 is bolted to the fixture mounting base 2. Supports 4 mounted on the working platform 1 are also connected to both sides of the fixture mounting base 2. An adjustment seat 5 is vertically mounted on the support 4. An endoscope 6 is horizontally mounted on the adjustment seat 5. The head of the endoscope 6 is aligned with the contour fixture 3, and the tail is electrically connected to the host display through a wire. An LED bead mounting hole 7 is also opened on the upper surface of the contour fixture 3. An LED light 8 is installed in the LED bead mounting hole 7. The tail of the LED light 8 is connected to an external power supply through a guide. The product to be inspected 18 is mounted on the contour fixture 3, and the LED light 8 is located at the lower end of the inner hole. The center line of the endoscope 6 is aligned with the inner hole of the product to be inspected 18.
[0021] refer to Figure 1 , Figure 2 , Figure 6 , Figure 7 and Figure 8 The work platform 1 is fixedly connected to the middle of the fixture mounting base 2, and the two sides of the fixture mounting base 2 are fixedly connected to the brackets 4. The center of the fixture mounting base 2 is bolted to the contour fixture 3. The product to be tested 18 is snapped onto the contour fixture 3, so that the MIC hole 20 in the middle of the right end is aligned and the endoscope 6 is installed. The SIM card hole 19 in the upper left end is also aligned and the endoscope 6 is installed. The two endoscopes 6 are limited and connected to the brackets 4 by the adjusting seat 5 to keep the endoscopes 6 parallel to the center line of the channel, so as to facilitate the observation of the channel. Two LED bead mounting holes 7 are opened deep in the corresponding MIC hole 20 and SIM card hole 19 of the contour fixture 3. LED lights 8 are installed in the holes to illuminate the channels of MIC hole 20 and SIM card hole 19 from the inside out, so that the endoscopes 6 can capture clear and complete images. The images are then updated on the host display in real time through the connecting line at the tail of the endoscope 6. The quality of these channels is judged by observing the image on the display.
[0022] The fixture mounting base 2 consists of a fixing plate 9 and a mounting plate 10. Screw holes 11 are provided at the four corners of the fixing plate 9 and the mounting plate 10. The mounting plate 10 is fixedly connected to the fixing plate 9 by bolts. The fixing plate 9 is fixedly connected to the work platform 1 by bolts. Two parallel wire grooves 12 are also provided on the top surface of the mounting plate 10. The wire grooves 12 are used to place the LED light 8 wires.
[0023] The protrusion 13 for supporting the product 18 to be tested is installed in the middle of the protrusion fixture 3. The front and rear ends of the protrusion fixture 3 are also equipped with countersunk holes 14 for receiving the bayonet and protrusions 15 for supporting the frame.
[0024] Reference image Figure 3 and Figure 4The fixing plate 9 is bolted to the working platform 1, and the mounting plate 10 is bolted to the fixing plate 9. The contour jig 3 is fixed to the mounting plate 10, aligning the lower end of the LED bead mounting hole 7 with the wire groove 12. After the LED light 8 is installed, the tail wire is connected to the external power supply through the wire groove 12, which can illuminate the channel from the inside out, making it convenient to display the channel pattern. The LED light 8 wire is hidden in the contour jig 3, so it will not interfere with the product to be tested 18. When the product to be tested 18 is connected to the contour jig 3, the protrusion 13 in the middle supports the product to be tested 18, the protrusions 15 in the middle of the front and rear ends provide auxiliary support, and the countersunk holes 14 at the four corners are used to place the buckles of the product to be tested 18. The channel illumination test is performed after the product to be tested 18 is positioned and connected.
[0025] The adjustment seat 5 has a connecting hole 16 at its horizontal center and a connecting hole 16 at its vertical edge. The corresponding vertical surfaces are also threaded with a tightening bolt 17. The bracket 4 and the endoscope 6 are respectively installed in the vertical and horizontal connecting holes 16, and their positions on the bracket 4 and the adjustment seat 5 are adjusted by the tightening bolt 17.
[0026] refer to Figure 5 Two connecting holes 16 connect the bracket 4 and the endoscope 6 respectively. A tightening bolt 17 is connected through the vertical connecting hole 16. The bracket 4 or the endoscope 6 is fastened to the adjusting seat 5 by tightening bolt 17. When in use, the bracket 4 and the adjusting seat 5 can be rotated to adjust the angle between the endoscope 6 and the product 18 to be tested. The endoscope 6 and the adjusting seat 5 or the bracket 4 can be moved up and down to adjust the corresponding height of the endoscope 6. The two can work together to align the endoscope 6 with the inner hole of the product 18 to facilitate testing.
[0027] This invention uses a contour jig to position and install the product to be inspected. An LED light on the contour jig is positioned directly below the channel, illuminating the channel from the inside. An endoscope at the outside is aligned with the channel, displaying the image of the channel on the host monitor. This allows for quick and intuitive judgment of the channel's quality, improving the inspection effect.
