Description

Technical Field

[0001] This utility model relates to the field of medical devices, specifically a cobalt-chromium alloy ceramic bracket laser cutting positioning fixture. Background Technology

[0002] Medical devices refer to instruments, equipment, appliances, in vitro diagnostic reagents and calibrators, materials and other similar or related items that are used directly or indirectly on the human body, including the necessary computer software. Medical devices include medical equipment and medical consumables. Their efficacy is mainly obtained through physical means, not through pharmacological, immunological or metabolic means, or although these means are involved, they only play an auxiliary role.

[0003] Cobalt-chromium alloy porcelain-fused-to-metal (PFM) frameworks are a commonly used material in the field of dental restoration, widely applied in the fabrication of crowns, bridges, and fixed orthodontic appliances. They possess high strength, good biocompatibility, and aesthetics, meeting diverse needs in dental restoration. However, traditional laser cutting and positioning jigs for cobalt-chromium alloy PFM frameworks typically require manual adjustment of multiple bolts or nuts for clamping, increasing operation time and labor intensity, and are relatively cumbersome, thus reducing the effectiveness of such jigs. Therefore, we propose a new laser cutting and positioning jig for cobalt-chromium alloy PFM frameworks to address these issues. Utility Model Content

A placement plate 7 is fixedly connected to the inner side wall of the positioning frame 5. A strip groove 8 is formed on the upper surface of the placement plate 7. Two clamping blocks 9 are placed on the upper surface of the placement plate 7. A linkage plate 12 is slidably connected inside each strip groove 8. An adjustment plate 22 is fixedly connected to the bottom end of each linkage plate 12. Two pneumatic cylinders 19 are fixedly installed on the inner side wall of the positioning frame 5. The telescopic end of each pneumatic cylinder 19 is fixedly connected to the side of the adjustment plate 22 that is far away from each other. A reinforcing ring 20 is fixedly connected to the outer surface of each pneumatic cylinder 19. The side of the two reinforcing rings 20 that are close to each other is fixedly connected to the left and right sides of the positioning frame 5, respectively.

[0023] In this embodiment, two support seats 2 are fixedly connected to the bottom surface of the fixing plate 1. Each support seat 2 has two mounting holes 3 on its upper surface, and each mounting hole 3 has a threaded inner ring. Multiple stabilizing plates 4 are fixedly connected to the bottom surface of the fixing plate 1. The left and right sides of the two stabilizing plates 4 are fixedly connected to the side of the support seat 2 that is close to each other. The support seats 2 facilitate the installation of the fixing plate 1. Two positioning bent plates 6 are fixedly connected to the upper surface of the fixing plate 1. The inner sidewall of each positioning bent plate 6 is fixedly connected to the outer surface of the positioning frame 5. The positioning bent plates 6 facilitate the reinforcement of the positioning frame 5. Flexible pads 10, made of rubber, are fixedly connected to the sides of the two clamping blocks 9 that are close to each other. The flexible pads 10 facilitate the reinforcement of the cobalt-chromium alloy ceramic bracket. Limiting plates 11 are fixedly connected to the front and back of the two clamping blocks 9. Sliding grooves 14 are provided on the front and back of the support base 2. Two sliding blocks 15 are slidably connected to the inner ring of each sliding groove 14. The sides of the two sets of sliding blocks 15 that are far apart from each other are fixedly connected to the sides of the limiting plates 11 that are close to each other. The limiting plates 11 facilitate the limiting of the clamping blocks 9.

[0024] In this embodiment, two reinforcing wedges 13 are fixedly connected to the upper surface of each adjusting plate 22. The sides of the two reinforcing wedges 13 that are close to each other are fixedly connected to the front and back sides of the linkage plate 12, respectively. The reinforcing wedges 13 facilitate the reinforcement of the linkage plate 12. Two guide rails 16 are provided on the inner sidewall of the support base 2. Two guide blocks 17 are slidably connected to the inner sidewall of each guide rail 16. The sides of the two guide blocks 17 that are close to each other are fixedly connected to the front and back sides of the adjusting plate 22, respectively. The cooperation of the guide blocks 17 and the guide rails 16 makes the adjusting plate 22 more stable when moving. Two sliding holes 18 are provided on the inner sidewall of the positioning frame 5. A sliding rod 21 is slidably connected to the inner ring of each sliding hole 18. The ends of the two sets of sliding rods 21 that are close to each other are fixedly connected to the sides of the adjusting plate 22 that are far apart from each other. The cooperation of the sliding rods 21 and the sliding holes 18 facilitates the positioning of the adjusting plate 22.

[0025] Working principle: First, connect the pneumatic cylinder 19 to the power supply and control it through the control switch. Activation of the pneumatic cylinder 19 pushes the adjusting plate 22, which in turn moves the linkage plate 12 and the clamping block 9. Since the strip groove 8 is compatible with the linkage plate 12, the linkage plate 12 slides within the strip groove 8, ensuring smooth and precise movement of the clamping block 9. A flexible pad 10 is fixedly connected to the inner wall of the clamping block 9. During the movement of the clamping block 9, the flexible pad 10 can closely fit the ceramic support, achieving stable clamping of the ceramic support. At the same time, limiting bending plates 11 are fixedly connected to both the front and back of the clamping block 9. The limiting bending plates 11 slide within the sliding groove 14 through the sliding block 15, further restricting the movement direction of the clamping block 9 and ensuring clamping stability. Thus, the positioning fixture can achieve rapid and stable clamping of the cobalt-chromium alloy ceramic support, improving the accuracy and efficiency of laser cutting.

[0026] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
