Specific implementation mode

[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0022] As Figures 1 - 3 shown, the embodiment of the present invention proposes a device for testing the strength of a conventional consolidated abrasive blank, including:

[0023] Workbench 1, on which a work rack 2 is connected through a mounting component. The mounting component includes a plurality of bolt holes provided on the work rack 2. A plurality of mounting bolts 16 are provided in the plurality of bolt holes. The plurality of mounting bolts 16 are respectively arranged in cooperation with the plurality of bolt holes, which is convenient for the staff to disassemble and install. A plurality of placing bases are fixedly connected to the side wall of the workbench 1 away from the work rack 2. The plurality of placing bases are all arranged in cooperation with the workbench 1, ensuring that the workbench 1 can be placed stably. A work slider 3 is slidably connected to the side wall of the work rack 2 close to the workbench 1. A continuously telescoping motor 4 is fixedly connected to the side wall of the work slider 3 close to the workbench 1. A test pressing plate is fixedly connected to the output end of the continuously telescoping motor 4. The continuously telescoping motor 4 is a prior art, and it can drive the test pressing plate to continuously rise and press down;

[0024] Reciprocating moving component; the reciprocating moving component includes a work groove 5 provided on the work slider 3. Two work racks 6 are fixedly connected in the work groove 5. The two work racks 6 are arranged symmetrically up and down. A positioning plate is fixedly connected to the work rack 2. A work rotating shaft 7 is rotatably penetrated through the positioning plate. The positioning plate provides a working position for the work rotating shaft 7 to prevent the work rotating shaft 7 from falling off during rotation. A half gear mechanism 8 is fixedly connected to the work rotating shaft 7. Both of the two work racks 6 are arranged in cooperation with the half gear mechanism 8. When the half gear mechanism 8 meshes and drives with the two work racks 6 respectively, it will drive the work slider 3 to slide left and right along the work rack 2. A transmission component is also provided on the work rack 2. The transmission component includes a work motor 9 fixedly connected to the side wall of the work rack 2 away from the work slider 3. The output end of the work motor 9 penetrates through the work rack 2. An auxiliary rotating shaft 10 is also fixedly connected to the output end of the work motor 9, so that the work motor 9 can drive the auxiliary rotating shaft 10 to rotate;

[0025] A bevel gear one 11 is fixedly connected to the auxiliary rotating shaft 10, and a bevel gear two 12 is fixedly connected to the working rotating shaft 7. The bevel gear one 11 and the bevel gear two 12 are meshed, so that when the working motor 9 works, the working rotating shaft 7 can be driven to rotate through gear transmission. There are also two fixing components on the workbench 1. The fixing component includes a fixing frame 13 fixedly connected to the workbench 1. A lifting screw rod 14 is threadedly connected to the fixing frame 13. The lifting screw rod 14 penetrates through the fixing frame 13. One end of the lifting screw rod 14 close to the workbench 1 is fixedly connected with a fixing clamping plate 15. Due to the characteristics of threaded connection, when the lifting screw rod 14 is rotated, the fixing clamping plate 15 will be driven to lift. A rotating handle is provided at one end of the lifting screw rod 14 away from the workbench 1. The rotating handle is arranged in a disc shape. The rotating handle and the lifting screw rod 14 are cooperatively arranged, which is more convenient for the staff to rotate the lifting screw rod 14.

[0026] During the use of the utility model, the staff first place the blank to be tested on the workbench 1, and then rotate the lifting screw rod 14. Due to the characteristics of threaded connection, the fixing clamping plate 15 fixedly connected thereto will start to move downward, so as to complete the fixation of the blank. Then the staff start the working motor 9 and the continuous telescopic motor 4. The working motor 9 will drive the auxiliary rotating shaft 10 to rotate, and then the bevel gear one 11 will rotate. Due to the characteristics of gear meshing, the bevel gear two 12 will also start to rotate, and then the working rotating shaft 7 will rotate;

[0027] Thereby driving the semi-gear mechanism 8 fixedly connected to the working rotating shaft 7 to rotate. Due to the characteristics of gear meshing, when the semi-gear mechanism 8 meshes with the two working racks 6 respectively, it will drive the working slider 3 to slide left and right reciprocally along the working frame 2, and then drive the continuous telescopic motor 4 to move together. The continuous telescopic motor 4 will drive the test pressing plate to continuously rise and press down, so as to realize the strength test of the surface of the blank. The staff only need to occasionally adjust the position of the blank according to the test requirements.

[0028] The above is only the preferred specific implementation manner of the utility model, but the protection scope of the utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the utility model, according to the technical solution of the utility model and its inventive concept, makes equivalent replacement or change, and should be covered within the protection scope of the utility model.
