Description

Technical Field

[0001] The invention relates to the technical field of resin hardness testing, in particular to a device for testing the hardness of a curing resin for dental implant molding. Background Art

[0002] During the actual processing and manufacturing process of resin glue, its hardness needs to be tested. The hardness of the resin is directly related to its service life. After the dental implant is installed in the mouth, medical resin glue is needed to seal the bolt holes of the dental implant. The quality of the resin glue is directly related to the service life of the dental implant. The color and transparency of the resin material are very similar to those of natural teeth, and the color of the filled dental implant is natural. After the light-cured resin is used for filling, the degree of curing will gradually increase over time, and the curing can be accelerated by ultraviolet light. After the resin glue is cured, a hardness tester is usually used to directly test the surface hardness. The current curing resin hardness testing device for dental implant molding is not convenient for simulating the adhesion strength of different dental implant resins and the fitting and anti-detachment effect of dental implants. It relies on the doctor's clinical experience to judge the resin curing time. At the same time, it is not convenient to test the hardness of the middle part of the resin. The hardness test is not comprehensive enough. When the resin is tested for hardness, the surface is not flat after the resin is injected into the dental implant, and the hardness test accuracy is poor. It is not convenient to automatically control the hardness needle to be perpendicular to the resin detection surface when testing the resin hardness.

[0039] Embodiment 2, on the basis of embodiment 1, the grinding control member 6 comprises: a grinding rotation shaft 601, a rotation driving gear 602, a lifting hydraulic cylinder 603, a sliding shell 604, a grinding block 605, an extrusion inclined surface 6051 and a fitting spring 606, the grinding rotation shaft 601 is rotatably connected to the suction cover 303; a rotation driving gear 602 is fixedly sleeved on the grinding rotation shaft 601; a gear on the output shaft of the driving motor 305 is meshed with the rotation driving gear 602; a lifting hydraulic cylinder 603 is fixedly installed on the grinding rotation shaft 601, and the lifting hydraulic cylinder 603 The output shaft passes through the flattened rotating shaft 601; a sliding shell 604 is fixedly installed at the bottom of the flattened rotating shaft 601; two grinding blocks 605 are slidably installed on the sliding shell 604; the bottoms of the two grinding blocks 605 are provided with grinding surfaces; the tops of the two grinding blocks 605 are respectively provided with extrusion inclined surfaces 6051; two fitting springs 606 are fixedly installed inside the sliding shell 604, and the other ends of the two fitting springs 606 are respectively connected to the sides of the two grinding blocks 605; the grinding blocks 605 are used to grind the top of the resin; the hardness test piece 7 includes: a lower pressure cylinder 701, a detection installation shell 701 1. Hardness testing ejector pin 702 and pressure plate 703, lower pressure cylinder 701 is slidably mounted on the flattened rotating shaft 601; the end of lower pressure cylinder 701 is attached to two extrusion inclined surfaces 6051; a testing installation shell 7011 is fixedly mounted on lower pressure cylinder 701; hardness testing ejector pin 702 is slidably plugged into lower pressure cylinder 701; the end of hardness testing ejector pin 702 is a conical structure; a pressure plate 703 is fixedly mounted on hardness testing ejector pin 702, and pressure plate 703 is sleeved inside testing installation shell 7011; hardness testing piece 7 also includes: testing spring 704, testing plate 7041 and hardness pressure sensor 705, which can adopt HZC-H1 type hardness pressure sensor 705 and pressure sensor 504, and adopt matching display 103, detection spring 704 is fixedly installed on pressure plate 703; detection spring 704 is sleeved inside detection mounting shell 7011; detection disk 7041 is sleeved inside detection mounting shell 7011; detection disk 7041 is connected to the end of detection spring 704; hardness pressure sensor 705 is fixedly installed inside detection mounting shell 7011, and the end of hardness pressure sensor 705 is attached to detection disk 7041;The hardness pressure sensor 705 is electrically connected to the display 103 on the rear side. The hardness test piece 7 can be used to detect the hardness of the resin surface. The compressive hardness effect of the resin can be detected by applying pressure and puncturing. At the same time, the flattening control piece 6 used in this structure can be used to flatten the resin surface before testing the hardness of the resin, so that the test surface of the resin is perpendicular to the hardness test pin 702, ensuring the accuracy of the test value and avoiding the problem of inaccurate hardness test caused by the hardness test pin 702 being inclined to the resin surface. The structure adopts two slidably separated grinding blocks 605, which can be automatically separated when the pressing cylinder 701 is pressed down for testing, ensuring the continuity of testing, making the structure more reasonable and the testing data accurate. The hardness testing ejector pin 702 squeezes the resin surface, and cooperates with the pressure of the testing spring 704. At this time, the pressure can be detected by the hardness pressure sensor 705. The larger the pressure value, the harder the resin surface is, and it is not easy to be pierced by the hardness testing ejector pin 702. The shorter the compression of the corresponding testing spring 704 is, the greater the elastic force is, so the larger the pressure value detected by the hardness pressure sensor 705 is. ;

[0040] The working principle of this embodiment is as follows: by rotating the opposite screw rods 201 to drive the two tooth simulation sliders 202 to move towards each other, the resin glue to be tested is poured into the grooves on the inner sides of the two tooth simulation sliders 202; the resin glue is irradiated by the ultraviolet curing lamp 304 to solidify it, and ink can be dripped on the top of the resin glue. At this time, the suction hood 303 can be driven down by the lifting and driving hydraulic cylinder 301, and the hood is buckled on the two tooth simulation sliders 202. The vacuum pump connected to the suction hood 303 is turned on for suction. If the resin and There is a gap between the tooth simulation sliders 202, which can accelerate the ink to penetrate into the gap, which is convenient for subsequent inspection. At the same time, when the suction hood 303 is sucking, the vent hole 1011 is used for ventilation during the negative pressure test. If the resin bonding is not strong enough, the negative pressure push cylinder 401 can push the resin out under the action of negative pressure; after the resin is cured, the middle traction shaft 502 can be magnetically attracted by the electromagnet 5011. At this time, the middle traction shaft 502 generates a downward pulling force, which drives the anti-slip protrusion 5021 to press down the resin, so as to detect the internal hardness of the resin. If the resin curing effect is not good, the anti-skid protrusion 5021 will squeeze the resin, and the downward displacement is large. At this time, the pressure can be detected by the pressure sensor 504 and displayed by the corresponding display 103. If the data deviation is large, it means that the internal hardness of the resin does not meet the standard; the driving motor 305 drives the rotating driving gear 602 to rotate, so as to drive the flattening rotating shaft 601 to rotate, and cooperates with the lifting driving hydraulic cylinder 301 to drive the grinding block 605 to press down, so that the two grinding blocks 605 can be driven to rub on the resin surface, and then the lifting hydraulic cylinder 603 can drive the pressing cylinder 701 to press down, and the bottom of the pressing cylinder 701 can squeeze the set extrusion inclined surface 6051, at this time, the two grinding blocks 605 can move outward and separate, compressing the fitting spring 606, and as the pressing cylinder 701 continues to press down, it can fit on the resin surface. In the process, the hardness detection ejector pin 702 can squeeze the resin surface, and cooperate with the pressure of the detection spring 704. At this time, the pressure can be detected by the hardness pressure sensor 705, and the larger the pressure value, the higher the hardness of the resin surface.
