Description

Technical Field

[0001] This application relates to the field of interfacial bonding strength testers, and in particular to an interfacial bonding strength tester for carbon-ceramic composite materials. Background Technology

[0002] Carbon-ceramic composites are multiphase composite materials with pyrolytic carbon, silicon carbide, etc. as the matrix and high-strength carbon fiber three-dimensional felt or braid as the reinforcing skeleton. They are recognized worldwide as ideal high-temperature structural materials, friction materials, and cryogenic materials. An interface bonding strength tester is a device used to measure the interfacial bonding strength of materials. It mainly simulates the forces that materials bear during use by applying pressure or tension, thereby evaluating the bonding strength between material interfaces. It is often used to test carbon-ceramic composites. In the conventional interface bonding strength test, after the machine body is installed and stabilized, the material to be tested is fixed to the upper end of the machine body with the help of the mounting bracket. After the impact mechanism at the top of the machine body is activated, it impacts the surface of the material to be tested, and the machine body records the test data, thereby detecting the bonding strength of the carbon-ceramic composite material.

[0003] Regarding the aforementioned technologies, the inventors believe that conventional interface bonding strength testers pose certain risks during use because the impact mechanism requires an impact hammer to strike the target when activated. Without surrounding protection, this can easily lead to accidental hand contact by the operator or collision with other objects, thus creating a risk during the use of the interface bonding strength tester.

[0004] The information disclosed in this background section is only intended to enhance the understanding of the background technology of this application, and therefore may include prior art that is not known to those skilled in the art. Utility Model Content

[0006] The carbon-ceramic composite material interfacial bonding strength tester provided in this application adopts the following technical solution:

[0007] A carbon-ceramic composite material interface bonding strength tester includes a body and a shield. A mounting frame and an impact mechanism are fixedly installed on the top of the body. A flip cover is rotatably connected to the surface of the shield, and the dimensions of the flip cover are compatible with those of the shield. A handle is fixedly installed on the surface of the flip cover, and a pull rope is fixedly connected to the inner wall of the flip cover. A winding reel is fixedly installed at one end of the pull rope. The bottom end of the shield is engaged with the top of the body, and the dimensions of the bottom end of the shield are compatible with those of the body. One end of the winding reel is rotatably connected to the inner wall of the shield.

[0008] Preferably, a fixing frame is welded to the surface of the shielding cover, and a first motor is fixedly installed on the top of the fixing frame. The output end of the first motor is fixedly connected to one end of the winding reel.

[0009] Preferably, a reset spring is fixedly installed on the top of the cover, and one end of the reset spring is fixedly connected to one end of the flip cover.

[0010] Preferably, two magnetic blocks are fixedly installed on the surfaces of both the shielding cover and the flip cover.

[0011] Preferably, the bottom end of the shield is connected to a connecting box, a second motor is fixedly connected to the surface of the connecting box, a rotating blade is fixedly installed at the output end of the second motor, and one end of the rotating blade is rotatably connected to the inner wall of the connecting box.

[0012] Preferably, a slide rail is slidably installed on the top of the connecting box, the top of the slide rail is fixedly connected to the bottom of the cover, and the dimensions of the inner wall of the slide rail are compatible with the dimensions of the top of the connecting box.

[0013] Preferably, a plurality of mounting blocks are fixedly installed at the bottom end of the shielding cover. The plurality of mounting blocks are divided into two groups. The two groups of mounting blocks are symmetrically distributed about the shielding cover. The inner wall of the mounting blocks is engaged with a buckle, and one end of the buckle is fixedly connected to the surface of the machine body.

[0014] In summary, this application includes the following beneficial technical effects:

[0015] 1. By installing a shielding cover on the surface of the machine body, with a flip cover installed on top of the shielding cover, and the inner wall of the flip cover connected to the surface of the take-up reel via a pull rope, the machine body surface can be shielded by the shielding cover and the flip cover. Rotating the take-up reel controls the pull rope to easily close the flip cover. A first motor is mounted on the surface of the shielding cover via a fixing bracket, and the output end of the first motor is connected to the surface of the take-up reel. The first motor, in conjunction with the pull rope, automatically controls the closing of the flip cover during machine operation. A return spring is installed between the shielding cover and the flip cover, so that the flip cover can be automatically opened after the pull rope releases its limit on the flip cover. Magnetic adsorption blocks are installed on the inner walls of both the shielding cover and the flip cover, so that the flip cover is kept connected to the shielding cover when the flip cover is closed. Compared with existing technologies, this method effectively improves the safety of the interface bonding strength tester.

[0016] 2. A connecting box can also be installed at the bottom of the shield cover. A second motor is installed on the surface of the connecting box, and a rotating blade is installed at the output end of the second motor. The rotating blade is controlled by the second motor to generate a negative pressure airflow to remove dust or debris generated during the testing of the top of the machine. The top of the connecting box is slidably connected to a slide rail at one end of the shield cover, so that the connecting box can be separated from the slide rail for easy emptying or cleaning of impurities inside the connecting box. Several mounting blocks are installed at the bottom of the shield cover. The inner wall of the mounting blocks is engaged with the surface of the machine body through snaps, so that the shield cover can be installed on the top of the machine body. This effectively improves the ease of use of the interface bonding strength tester. Attached Figure Description

Detailed Implementation

Figure 1 - Figure 2The instrument includes a body 1 for an interface bonding strength tester. In use, after the body 1 is installed stably, the material to be tested is fixed to the upper part of the body 1 using a mounting bracket 2. After the impact mechanism 3 at the top of the body 1 is activated, it impacts the surface of the material to be tested, and the test data is recorded by the body 1, thereby detecting the bonding strength of the carbon-ceramic composite material. A shielding cover 4 is installed on the surface of the body 1. A flip cover 5 is installed on the top of the shielding cover 4. A handle 6 is connected to the surface of the flip cover 5, which facilitates opening the flip cover 5. A pull rope 7 is installed on the inner wall of the flip cover 5. One end of the pull rope 7 is connected to the surface of the take-up reel 8 inside the shielding cover 4. The shielding cover 4 and the flip cover 5 shield the surface of the body 1, and rotating the take-up reel 8 controls the pull rope 7 to facilitate closing the flip cover 5.

[0024] Reference Figure 2 A first motor 10 is mounted on the surface of the cover 4 via a fixing bracket 9. The output end of the first motor 10 is connected to the surface of the take-up reel 8. After the first motor 10 is started, it controls the take-up reel 8 to wind up the pull rope 7, thereby automatically controlling the flip cover 5 to close when the machine body 1 is running. A return spring 12 is installed between the cover 4 and the flip cover 5. The return spring 12 pushes the flip cover 5, thereby controlling the flip cover 5 to open automatically after the pull rope 7 releases the limit on the flip cover 5, which is more convenient to use. Magnetic adsorption blocks 11 are installed on the inner walls of both the cover 4 and the flip cover 5. When the flip cover 5 is closed, the adsorption blocks 11 keep the flip cover 5 connected to the cover 4.

The top of the connecting box 13 is slidably connected to the slide rail 16 at one end of the cover 4. Separating the connecting box 13 from the slide rail 16 makes it easy to pour out or clean the impurities inside the connecting box 13. Several mounting blocks 17 are installed at the bottom of the cover 4. The inner wall of the mounting block 17 is engaged with the buckle 18 on the surface of the machine body 1.

Rotating the take-up reel 8 controls the pull rope 7 to easily close the flip cover 5. A first motor 10 is installed on the surface of the shielding cover 4 with the help of a fixing frame 9. The output end of the first motor 10 is connected to the take-up reel 8. The surface of the reel 8 is connected so that after the first motor 10 is started, the reel 8 can be controlled to wind the pull rope 7, thereby automatically controlling the flip cover 5 to close when the machine body 1 is running. A return spring 12 is installed between the cover 4 and the flip cover 5 so that the flip cover 5 can be pushed by the return spring 12, thereby controlling the flip cover 5 to open automatically after the pull rope 7 releases the limit on the flip cover 5, which is more convenient to use. Magnetic adsorption blocks 11 are installed on the inner walls of both the cover 4 and the flip cover 5 so that the flip cover 5 can be kept connected to the cover 4 by the adsorption blocks 11 when the flip cover 5 is closed.

[0027] A connecting box 13 can also be installed at the bottom of the cover 4. A second motor 14 is installed on the surface of the connecting box 13. A rotating blade 15 is installed at the output end of the second motor 14 so that the rotating blade 15 can be rotated by the second motor 14 to form a negative pressure airflow to remove dust or debris generated during the inspection of the top of the body 1. The top of the connecting box 13 is slidably connected to the slide rail 16 at one end of the cover 4 so that the connecting box 13 can be separated from the slide rail 16 to facilitate the pouring out or cleaning of impurities in the connecting box 13. Several mounting blocks 17 are installed at the bottom of the cover 4. The inner wall of the mounting block 17 is engaged with the buckle 18 on the surface of the body 1 so that the cover 4 can be installed on the top of the body 1.
