Description

Technical Field

[0001] This utility model relates to the field of testing tooling technology, and in particular to a testing device for broken or missing parts of dental braces. Background Technology

[0002] With the rapid development of technology, the manufacturing industry is demanding increasingly higher standards for its products. To enhance connection strength, wear resistance, rust prevention, and shock resistance, and to extend the service life of internal threads on products, threaded inserts are used in assembly to ensure the overall durability and reliability of the product. Threaded inserts (also known as wire inserts or wire thread inserts) are a type of internal thread fastener made of high-precision, high-strength stainless steel wire. They can also strengthen and protect the internal threads of low-strength materials. Therefore, threaded inserts are widely used in automotive industries such as aluminum alloy shock absorbers, engines, and transmissions.

[0003] In the assembly of threaded inserts, the process primarily involves manual installation using assembly tools or semi-automatic assembly stations to accurately install the inserts into the threaded holes of the workpiece. Due to the large number of threaded inserts assembled on the same workpiece, instances of missing inserts are inevitable. Therefore, after assembly, threaded insert inspection is required. Manual visual inspection is prone to omissions, and the inspection of the threaded insert ends is susceptible to inaccurate detection of broken ends, making it difficult to guarantee product quality. Utility Model Content

[0004] Therefore, it is necessary to provide a detection device for broken or missing braces.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A detection device for broken or missing braces includes: a detection box body, a detection box cover, a pad, and a fixture plate. A power interface is provided on the rear side wall of the detection box body. The detection box cover is placed on the detection box body, and qualified indicator lights and defective indicator lights are respectively provided on both sides of the detection box cover. The pad is placed above the detection box cover, and a sliding groove is provided on the upper end surface of the pad, which is connected to the lower end surface of the detection box cover. The fixture plate is placed above the pad, and a detection groove is provided on the upper end surface of the fixture plate. Limiting holes are provided on both sides of the detection groove, and detection sensing components are provided in each of the limiting holes. The bottom of the detection sensing components is connected to the sliding groove.

[0006] In one embodiment, a plurality of pins are provided on the outer side of the upper end face of the detection groove, the pins being used for positioning the workpiece.

[0007] In one embodiment, the detection groove is further provided with a contouring part in the middle, which matches the shape of the bottom of the workpiece.

[0008] In one embodiment, the detection sensing component includes a first positioning block and a second positioning block stacked within a limiting hole, with the first positioning block located below the second positioning block; the first positioning block has two mounting through holes, each containing a tooth tail sensing post and a brace sensing post; the second positioning block has a countersunk through hole, with both the tooth tail sensing post and the brace sensing post located inside the countersunk through hole.

[0009] In one embodiment, the upper end of the tooth tail sensing post extends above the second positioning block, and the height of the tooth sleeve sensing post is less than the height of the upper end of the countersunk hole section in the countersunk through hole.

[0010] In one embodiment, a sensing head is further provided inside the countersunk through hole, and the sensing head is sleeved inside the tooth tail sensing post.

[0011] In one embodiment, a reset spring is provided at the bottom of the sensing head and is fixedly connected to the first positioning block. The upper end of the reset spring is fixedly connected to the bottom of the sensing head, and the lower end of the reset spring is fixedly connected to the first positioning block.

[0012] In one embodiment, the height of the lower end face of the sensor head is greater than the height of the upper end face of the braces sensor post.

[0013] In one embodiment, there are two qualified indicator lights, each corresponding to a detection sensing component; an alarm is also provided on one side of the defective indicator light.

[0014] In one embodiment, a power switch and a power indicator light are also provided on the front side wall of the detection box.

[0015] The beneficial effects of this utility model are as follows: This utility model provides a detection device for broken or missing parts of dental braces. A detection groove is set on a fixture plate, and a contoured part set in the detection groove cooperates with the insert pins surrounding the detection groove to facilitate workpiece positioning. After the workpiece is placed in position, the threaded dental brace in the workpiece presses against the thread end sensing column and the sensing head. The sensing head presses down to contact the thread end sensing column. The thread end sensing column and the thread end sensing column in the detection sensing component independently detect broken or missing parts of the dental brace. When the workpiece is correctly installed and there is no broken part, the thread end sensing column and the thread end sensing column are pressed and trigger a qualified signal, and the corresponding qualified indicator light illuminates. If there is a broken part or a missing part, the sensing head is not fully pressed down, or the thread end sensing column does not contact the workpiece, the system judges it as defective and triggers an audible and visual alarm. This device, through the coordinated work of the two sensing columns, achieves accurate judgment of the dental brace fitting quality, improves the product detection efficiency and accuracy, and effectively avoids quality risks caused by human error.

[0024] In one embodiment, such as Figure 1 and Figure 2 As shown, a detection device 10 for broken or missing braces includes: a detection box 100, a detection box cover 200, a pad 300, and a fixture plate 400. The detection box 100 has a power interface on its rear side wall. The detection box cover 200 covers the detection box 100, and two sides of the cover are respectively provided with a pass indicator light 210 and a fail indicator light 220. The pad 300 is positioned above the detection box cover 200, and its upper surface has a sliding groove 310 that connects to the lower surface of the cover 200. The fixture plate 400 is positioned above the pad 300, and its upper surface has a detection groove 410. Limiting holes 420 are provided on both sides of the detection groove 410, and each limiting hole 420 contains a detection sensing component 500. The bottom of each detection sensing component 500 is connected to the sliding groove 310.

[0025] In this embodiment, a control circuit board is provided inside the testing chamber 100, and a power interface is provided on the rear side wall of the testing chamber 100. The power cord is connected to the control circuit board through the power interface. A testing chamber cover 200 is provided on the top of the testing chamber 100. A pass indicator light 210 and a fail indicator light 220 are provided on the testing chamber cover 200 to display the testing results. A pad 300 is provided above the testing chamber cover 200. The pad 300 is provided with a sliding groove 310. The sliding groove 310 is cross-shaped and communicates with the lower end face of the testing chamber cover 200. A fixture plate 40 is also provided. The fixture plate 400 is fixed above the pad 300. The upper surface of the fixture plate 400 has a detection groove 410, and limiting holes 420 are provided on both sides of the detection groove 410, connecting the upper and lower surfaces of the fixture plate 400. Two detection sensing components 500 are respectively located within the two limiting holes 420, and the bottom of each detection sensing component 500 is slidably connected to the sliding groove 310. Depending on different detection requirements, the position of the detection sensing component 500 can be adjusted along the sliding groove 310. By replacing different fixture plates 400, different specifications of dental braces can be adapted, improving the versatility of the detection. By placing the workpiece in the detection groove 410, the detection sensing components 500 are used to detect broken or missing parts of the dental braces.

[0026] To facilitate the positioning of the workpiece within the testing groove 410, multiple inserts 411 are provided around the edge of the testing groove 410. The inserts 411 are embedded in the surface of the fixture plate 400, and the top of the inserts 411 protrudes from the upper surface of the testing groove 410. The multiple inserts 411 are fixed at the four corners of the testing groove 410 to accurately position the dental brace to be tested. A contour part 412 is provided in the middle of the testing groove 410. The shape of the contour part 412 matches the shape of the bottom of the workpiece to limit the horizontal displacement of the workpiece within the testing groove 410 and ensure that the workpiece remains stable during the testing process.

[0027] like Figure 3 and Figure 4As shown, in order to accurately detect whether the braces are broken or missing, the detection sensing component 500 includes a first positioning block 510 and a second positioning block 520 that are stacked and fixed together, with the first positioning block 510 located above the second positioning block 520; the first positioning block 510 has two mounting through holes, in which a tooth tail sensing post 511 and a braces sensing post 512 are respectively installed, and the bottoms of both the tooth tail sensing post 511 and the braces sensing post 512 are electrically connected to the control circuit board; the side wall of the first positioning block 510 has a threaded hole, the thread... The hole communicates with the mounting through hole and has a locking screw in the threaded hole to fix the position of the tooth tail sensing post 511 and the tooth sleeve sensing post 512; the second positioning block 520 has an inverted countersunk through hole 530, which includes a countersunk hole section with a larger diameter and a light hole section with a smaller diameter. The tooth tail sensing post 511 extends through the countersunk through hole 530 to the top of the second positioning block 520; the upper end face of the tooth sleeve sensing post 512 is located in the countersunk hole section, and the height of the upper end of the tooth sleeve sensing post 512 is less than the height of the upper end of the countersunk hole section.

[0028] Furthermore, a T-shaped sensing head 540 is provided inside the countersunk through hole 530. The sensing head 540 has a connecting hole and is sleeved on the tooth tail sensing post 511 through the connecting hole. A return spring 550 is provided at the bottom of the sensing head 540. The return spring 550 is a compression spring. One end of the return spring 550 is fixedly connected to the bottom of the sensing head 540, and the other end is fixedly connected to the upper end face of the first positioning block 510. The sensing head 540 can slide up and down along the tooth tail sensing post 511. The height of the lower end face of the sensing head 540 is higher than the height of the upper end face of the dental brace sensing post 512. That is, when the return spring 550 is supporting the sensing head 540, the dental brace sensing post 512 is located below the sensing head 540 and does not contact the sensing head 540. During testing, after the workpiece is placed in the testing slot 410, the workpiece is pressed down, and the bottom of the threaded sleeve on the workpiece pushes the sensing head 540 downward, so that the sensing head 540 contacts the sleeve sensing post 512, and the end of the threaded sleeve contacts the end sensing post 511 and triggers a signal, causing the qualified indicator light 210 to light up, indicating that the workpiece sleeve is installed completely and there is no broken end.

[0029] To facilitate more intuitive observation of the test results, two qualified indicator lights 210 are installed on the test chamber cover 200, one on each side. A defective indicator light 220 is installed on the other side. An alarm 230, a buzzer alarm, is also installed on the test chamber cover 200. All three indicator lights (210, 220, and 230) are electrically connected to the control circuit board, and each of the two qualified indicator lights 210 corresponds to one of the two detection sensing components 500. When any detection sensing component 500 fails to receive a signal, the corresponding qualified indicator light 210 turns off, the defective indicator light 220 illuminates, and the alarm 230 simultaneously emits a warning sound, alerting the operator to any missing parts or broken ends in the workpiece.

[0030] To facilitate the start and stop of the testing process, a power switch 110 and a power indicator light 120 are provided on the testing chamber 100. The power switch 110 controls the connection and disconnection of the power supply and the control circuit board, and the power indicator light 120 is used to display the power supply working status.

[0031] The general workflow of this utility model is as follows: Power is turned on, the workpiece is placed in the detection slot 410, aligning the positioning hole on the workpiece with the insert pin 411. The workpiece is pressed down, causing the bottom of the threaded sleeve on the workpiece to contact and press down the sensing head 540, so that the bottom of the sensing head 540 contacts the upper surface of the threaded sleeve sensing post 512. Simultaneously, the thread tail of the threaded sleeve contacts the thread tail sensing post 511, activating the circuit. Both qualified indicator lights 210 illuminate, indicating that the workpiece threaded sleeve is properly installed and without broken ends. If any detection point is not triggered, the corresponding qualified indicator light 210 goes out, the defective indicator light 220 illuminates, and the alarm 230 sounds, indicating the presence of a defect. The operator can immediately remove the workpiece for inspection. After the inspection is completed, the workpiece is released, the return spring 550 pushes the sensing head 540 back to its original position, the sensing post separates from the sensing head 540, the circuit is disconnected, the qualified indicator light 210 goes out, and the equipment returns to its initial state, awaiting the next inspection cycle. The entire process is responsive and precise, effectively improving detection efficiency and reliability, reducing the risk of human error, and improving product quality.

[0032] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here.
