A test needle 8 and a cover plate 9 are respectively fixedly provided on the surface of the auxiliary ring 5. A guiding box 10 is fixedly provided on the front surface of the protection block 2. A sliding plate 13 is slidably connected to the inner wall of the guiding box 10. A clamping block 14 that is engaged with the square groove 11 is fixedly provided on the back surface of the sliding plate 13. A return spring 17 is fixedly provided between the sliding plate 13 and the guiding box 10. The return spring 17 will extend and push the sliding plate 13 and the clamping block 14, causing the clamping block 14 to insert into the square groove 11 to complete the fixation of the rotating rod 4. The cover plate 9 rotates 180° clockwise with the rotating rod 4 as the center. At this time, the cover plate 9 slides into the interior of the receiving groove 3, and the surface of the cover plate 9 fits with the inner wall of the receiving groove 3, thereby protecting the test needle 8 inside the receiving groove 3.

[0025] A slot 12 for the surface of the clamping block 14 to slide is formed on the front surface of the protection block 2. The interior of the slot 12 is communicated with the interior of the square groove 11. A buffer pad 20 is embedded in the inner wall of the receiving groove 3. The inner wall of the receiving groove 3 is slidably connected to the surface of the auxiliary ring 5. A handle 21 is fixedly provided on the surface of the cover plate 9. The test needle 8 rotates 180° clockwise with the rotating rod 4 as the center. At this time, the test needle 8 slides into the interior of the receiving groove 3, and the buffer pad 20 fits with the test needle 8. The buffer pad 20 buffers the flipped test needle 8.

[0026] A sliding tube 15 is fixedly provided on the front surface of the sliding plate 13. A sliding rod 16 is slidably connected to the inner wall of the sliding tube 15. One end of the sliding rod 16 is fixedly connected to the inner wall of the front surface of the guiding box 10. The return spring 17 is sleeved outside the sliding tube 15. A sliding groove 18 is formed on the surface of the guiding box 10. A push plate 19 is slidably connected to the inner wall of the sliding groove 18. One side of the push plate 19 is fixedly connected to one side of the sliding plate 13. By moving the push plate 19, the push plate 19 drives the sliding plate 13 to move. The sliding plate 13 will compress the return spring 17 and push the sliding tube 15. The sliding tube 15 slides along the surface of the sliding rod 16. The sliding rod 16 limits the return spring 17 through the sliding tube 15, avoiding excessive bending of the return spring 17 when it is compressed and extending the service life of the return spring 17.

[0027] The protractor assembly 6 includes an anti - detachment assembly 7 and two brackets 61. One of the brackets 61 is rotatably arranged on the front surface of the amplitude plate 1 through a rotating shaft, and the other bracket 61 is rotatably arranged on the back surface of the amplitude plate 1 through a rotating shaft. The bottom ends of the two brackets 61 are fixedly provided with bases 66. The surfaces of the two brackets 61 are both fixedly provided with graduated disks 62. Arc - shaped grooves 63 are opened on the surfaces of the two graduated disks 62. Transmission rods 64 are slidably connected to the inner walls of the two arc - shaped grooves 63. Needles 65 are fixedly provided on the surfaces of the two transmission rods 64. One end of one transmission rod 64 is fixedly connected to the front surface of the amplitude plate 1, and one end of the other transmission rod 64 is fixedly connected to the back surface of the amplitude plate 1. A through - slot 67 is opened on the surface of one of the brackets 61, and a lifting slot 68 is opened on the surface of the other bracket 61. The amplitude plate 1 can rotate around the rotating shaft. When testing an inorganic mineral casting, first, the test needle 8 is brought into contact with the surface of the workpiece to be tested. Then, the vibration force generated by an external vibration device acts on the surface of the workpiece to be tested. The vibration force is transmitted through the test needle 8 to the auxiliary ring 5, the rotating rod 4, the protective block 2, and the amplitude plate 1, driving the amplitude plate 1 to rotate. The amplitude plate 1 drives the needle 65 to rotate through the transmission rod 64, causing the needle 65 to rotate on the surface of the graduated disk 62. Finally, the change in the angle is observed by the human eye. The change in the angle is the vibration amplitude of the workpiece, and this vibration amplitude is recorded to complete the test of the vibration absorption performance of the inorganic mineral casting.

The surface of the lifting seat 72 is slidably connected to the inner wall of the lifting slot 68. One end of the transmission lead screw 71 penetrates through the inner wall of the top end of the through - slot 67 and is fixedly provided with a turntable. Rotating the turntable drives the transmission lead screw 71 to rotate. The transmission lead screw 71 drives the lifting seat 72 to move upward. The lifting seat 72 drives the diagonal pressure block 73 to move. The diagonal pressure block 73 pushes the protective block 2 that is already between the two brackets 61 through the first rubber block 74, causing the protective block 2 to fit with the second rubber block 76, completing the fixation of the protective block 2 and preventing the protective block 2 from shaking during the transportation of the entire casting testing machine, which is convenient for transportation.

[0029] When in use, first pull the push plate 19, the push plate 19 drives the slide plate 13 to move, the slide plate 13 compresses the reset spring 17, the slide plate 13 will drive the block 14 to move, so that the block 14 is separated from the square groove 11, then hook the handle 21 and rotate the cover plate 9 clockwise with the rotating rod 4 as the center, the cover plate 9 drives the test needle 8 to rotate through the auxiliary ring 5, the test needle 8 rotates clockwise with the rotating rod 4 as the center, and the test needle 8 slides into the interior of the storage groove 3. At this time, the cover plate 9 will slide into the interior of the storage groove 3 and fit with the inner wall of the storage groove 3, thereby isolating the test needle 8 from the outside world, and then protecting the test needle 8 during transportation and idle placement to prevent the test needle 8 from being damaged by foreign objects. Release the push plate 19, the reset spring 17 will extend and push the slide plate 13 and the block 14 to move in the opposite direction, and the block 14 is stuck in the square groove 11, completing the fixation of the cover plate 9 and consolidating the protective effect of the cover plate 9. The buffer pad 20 can buffer the test needle 8 to prevent the test needle 8 from being damaged by collision when it is turned over.

[0030] It should be emphasized that the clamping block 14 can be clamped into the square groove 11 before the test needle 8 rotates, thereby fixing the rotating rod 4, the auxiliary ring 5 and the test needle 8 exposed outside the receiving groove 3, so as to measure the vibration absorption of the inorganic mineral casting through the test needle 8, the rotating rod 4, the auxiliary ring 5, the protective block 2, the amplitude plate 1 and the measuring angle assembly 6;

[0031] Furthermore, after storing the test needle 8, the amplitude plate 1 is rotated counterclockwise with the rotating shaft at the top of the bracket 61 as the center, and the amplitude plate 1 drives the protective block 2 to rotate until the protective block 2 is supported by the second rubber block 76. At this time, the turntable is rotated, and the turntable drives the transmission screw 71 to rotate, and the transmission screw 71 drives the lifting seat 72 to move upward, and the lifting seat 72 drives the oblique pressure block 73 and the first rubber block 74 to move, and the first rubber block 74 pushes the protective block 2, causing the protective block 2 to press the second rubber block 76, completing the fixation of the protective block 2, preventing the protective block 2 and the amplitude plate 1 from shaking when transporting the entire casting testing machine, and facilitating transportation.
