Description

Technical Field

[0001] The utility model relates to the technical field of inorganic mineral castings, in particular to a performance testing device for high-strength inorganic mineral castings. Background Technique

[0002] The product of mineral casting is a mineral casting, which is an environmentally friendly material for the future. As a structural part of a machine, it can replace traditional cast iron in some applications due to its price and performance advantages. One is a resin mineral casting with resin glue as the binder, and the other is a polymer mineral casting with polymer nano powder as the penetrant.

[0003] Mineral castings are usually formed by die casting. With the development of precision casting technology and the popularization of mechanized and intelligent equipment, the impact resistance of mineral castings has become increasingly important. Good impact resistance can greatly reduce the limitations of the application of automated equipment. Therefore, during the processing of mineral castings, it is necessary to test the impact resistance of mineral castings, so a testing device is needed to test it.

[0004] At present, most of the performance tests on castings on the market are to place the mineral casting above the base, and then the staff controls the punching block to hit the mineral casting to see if there are dents and pits on the surface of the casting to judge its impact resistance. However, during the process of the punching block hitting the mineral casting, the casting will move and pop out under the impact force, thus affecting the stability during the detection process. And during the process of the punching block falling, it is easy to injure the staff and affect the use safety. Content of the Utility Model

[0005] The purpose of the utility model is to provide a performance testing device for high-strength inorganic mineral castings to solve the problems mentioned in the above background technique that during the testing process of the testing device, when the punching block hits the mineral casting, the casting will move and pop out under the impact force, thus affecting the stability during the detection process, and during the process of the punching block falling, it is easy to injure the staff and affect the use safety. To achieve the above purpose, the utility model provides the following technical scheme: A performance testing device for high-strength inorganic mineral castings, including a testing table, a testing machine body is installed on the top of the testing table, a punching block is clamped at the bottom of the testing machine body, protective plates are slidably connected to both ends of the testing table, a lifting mechanism is arranged at the bottom of the protective plates for driving the protective plates to lift, an inorganic mineral casting body is placed on the surface of the testing table, and a clamping mechanism is installed on the surface of the testing table for restricting the sliding of the inorganic mineral casting body.

[0006] Preferably, the lifting mechanism includes a fixed rod fixed to the bottom of the test bench. An fixing plate is fixedly sleeved outside the fixed rod. A first motor is fixed to the bottom of the fixing plate. A screw rod is fixed to the output end of the first motor. A nut is sleeved outside the screw rod. Connecting plates are provided at both ends of the nut in terms of height. An installation column is fixed to the top of the connecting plate. The installation column is fixedly connected to the protection plate.

[0007] Preferably, the screw rod is rotatably connected to the fixing plate, and the connecting plate is slidably connected to the fixed rod.

[0008] Preferably, sliding grooves for slidably connecting the protection plate are provided on both sides of the test bench.

[0009] Preferably, the clamping mechanism includes an installation block fixedly embedded on the surface of the test bench. An installation plate is fixed to the top of the installation block. A second motor is fixed to the bottom of the installation block. A rotating shaft is fixed to the output end of the second motor. A crank is sleeved outside the rotating shaft. A sector gear is fixedly provided on the outer circumference of the crank. A clamping rod is hinged to the end of the crank. A clamping plate is fixed to the end of the clamping rod. A connecting rod is hinged to the end of the clamping rod. The other end of the connecting rod is hinged to the installation plate.

[0010] Preferably, there are two sector gears, and the two sector gears mesh with each other. The clamping plate is in contact with the inorganic mineral casting body.

[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0012] In the present utility model, when the second motor is started to drive the rotating shaft to drive the crank to rotate, the sector gear at its end also rotates and meshes with the sector gear at the other end, so that the cranks at both ends drive the clamping rods to rotate at the same time. At the same time, the crank also rotates. The clamping plates at the ends of the clamping rods then fit against both ends of the inorganic mineral casting body to clamp and fix it, so that the inorganic mineral casting will not slide when being tested, thereby improving the stability during the detection process.

[0013] In the present utility model, when the first motor is started to drive the screw rod to rotate, the nut sleeved outside it immediately drives the connecting plate to slide up along the fixed rod. At the same time, the protection plate also slides up to protect and block both ends of the test bench, avoiding injury to the staff during the process of the punching block falling, and improving the safety of use.

[0028] It should be noted that the test body 2 consists of a lifting platform and a clamping chuck. The falling height of the stamping block 3 is adjusted by the lifting platform, and the stamping block 3 is clamped by the clamping chuck. When testing, the clamping chuck is loosened to make the stamping block 3 fall and hit the mineral casting to achieve the test effect. However, its test structure belongs to the prior art and is not the main innovative point structure, so it will not be elaborated in detail.

[0029] In this embodiment, as Figure 1 、 Figure 2 、 Figure 3 and Figure 4 shown, the lifting mechanism 5 includes a fixed rod 51 fixed to the bottom of the test bench 1. An fixing plate 52 is fixedly sleeved outside the fixed rod 51. A first motor 53 is fixed to the bottom of the fixing plate 52. A screw rod 54 is fixed to the output end of the first motor 53. A nut 55 is sleeved outside the screw rod 54. There are connecting plates 56 at both ends of the nut 55 in height. An installation column 57 is fixed to the top of the connecting plate 56. The installation column 57 is fixedly connected to the protection plate 4.

[0030] In this embodiment, as Figure 1 、 Figure 2 、 Figure 3 and Figure 4 shown, the screw rod 54 is rotatably connected to the fixing plate 52, and the connecting plate 56 is slidably connected to the fixed rod 51.

[0031] It should be noted that there are two protection plates 4, which are respectively distributed at both ends of the test bench. The two protection plates 4 are lifted and lowered simultaneously to block the falling process of the stamping block 3, so as to prevent the stamping block 3 from popping out and hitting the staff.

[0032] In this embodiment, as Figure 1 、 Figure 2 、 Figure 3 and Figure 4 shown, sliding grooves for the sliding connection of the protection plate 4 are provided on both sides of the test bench 1.

[0033] In this embodiment, as Figure 1 、 Figure 2 、 Figure 3 and Figure 4 shown, the clamping mechanism 7 includes an installation block 71 fixedly embedded on the surface of the test bench 1. An installation plate 72 is fixed to the top of the installation block 71. A second motor 73 is fixed to the bottom of the installation block 71. A rotating shaft 74 is fixed to the output end of the second motor 73. A crank 75 is sleeved outside the rotating shaft 74. A sector gear 76 is fixed to the outer circumference of the crank 75. A clamping rod 77 is hinged to the end of the crank 75. A clamping plate 78 is fixed to the end of the clamping rod 77. A connecting rod 79 is hinged to the end of the clamping rod 77. The other end of the connecting rod 79 is hinged to the installation plate 72.

[0034] In this embodiment, asFigure 1 , Figure 2 , Figure 3 and Figure 4 As shown in Figure 3 , Figure 4 , there are two sector gears 76, which are meshed with each other. The clamping plate 78 is in contact with the inorganic mineral casting body 6.

[0035] It should be noted that a parallelogram mechanism is formed by the sector gear 76, the crank 75, the clamping rod 77 and the connecting rod 79. The two parallelogram mechanisms move synchronously through the transmission of the two sector gears 76.

[0036] It should be noted that there are two sector gears 76, and a rotating shaft 74 is provided in the middle of each of them. The rotating shaft 74 connecting one end of the second motor 73 is rotatably connected between the mounting block 71 and the mounting plate 72. The rotating shaft 74 in the middle of the other sector gear 76 is fixed between the mounting block 71 and the mounting plate 72 to support the other sector gear 76. When the first sector gear 76 rotates, it meshes with the other sector gear 76, causing the two cranks 75 to be stressed and rotate simultaneously, thereby driving the clamping rod 77 to rotate and clamp.

[0037] It should be noted that the specific model specifications of the first motor 53 and the second motor 73 need to be selected according to the actual specifications of the device, etc. The specific selection calculation method adopts the existing technology in the field, so it will not be elaborated here.

[0038] The usage method and advantages of the present utility model: When the high-strength inorganic mineral casting performance testing device is working, the working process is as follows:

[0039] As Figure 1 , Figure 2 , Figure 3 and Figure 4 shown, first, place the inorganic mineral casting body 6 to be tested on the test bench 1, start the second motor 73 to drive the rotating shaft 74 to rotate in the mounting block 71. When the rotating shaft 74 rotates, the crank 75 rotates immediately. At the same time, the sector gear 76 on the end side of the crank 75 also rotates and then meshes with the sector gear 76 at the other end, causing the two cranks 75 at both ends to rotate simultaneously, thereby driving the clamping rod 77 to rotate. At the same time, the connecting rod 79 also rotates until the clamping plate 78 at the end of the clamping rod 77 fits tightly against both ends of the inorganic mineral casting body 6 and then stops driving, so that the inorganic mineral casting will not slide when being impacted during the testing process, thereby improving the stability during the detection process;

[0040] Secondly, start the first motor 53 to drive the screw 54 to rotate. When the screw 54 rotates, the nut 55 sleeved outside it will be threadedly engaged with it and then slide upward. When sliding upward, the protection plate 4 installed on the top of the connecting plates 56 at both ends of the nut 55 through the mounting posts 57 will slide upward along the test bench 1 to shield and protect both ends of the test bench 1, avoiding injury to the staff during the falling process of the stamping block 3 and improving the use safety;

[0041] Finally, start the stamping block 3 at the upper end of the test body 2 to fall and hit the inorganic mineral casting body 6, and check whether there are depressions and pits on the surface of the casting to judge its impact resistance, so as to achieve the test effect.
