DETAILED DESCRIPTION

[0037] The following is combined with Figure 1-12 This application is further described in detail.

[0038] Please refer to Figure 1 , Figure 2 , Figure 3 and Fig.12A multi-head electric ceramic stove component aging test device includes a test bench 1 with a placement slot on the upper part and a plurality of test dishes 3. A multi-head electric ceramic stove body 2 is placed in the placement slot of the test bench 1. The plurality of test dishes 3 are located on the upper part of the multi-head electric ceramic stove body 2 and are centrally symmetrically distributed on the upper part of the multi-head electric ceramic stove body 2. A shell 4 is fixedly arranged directly above the test bench 1. A test mechanism 5 is arranged inside the shell 4 to cooperate with the test dishes 3 to test the multi-head electric ceramic stove body 2. A driving mechanism 6 is arranged on the right side wall of the shell 4. The testing mechanism 5 includes a calibration component 51, a collision component 52 and a pushing component 53. The calibration component 51, the collision component 52 and the pushing component 53 are arranged on the inner side of the shell 4 from top to bottom in sequence, and the collision component 52 and the pushing component 53 are driven by the driving mechanism 6. The bottom end of the test dish 3 is provided with a base 24, the vertical section of the base 24 is T-shaped, and the outer thread of the base 24 is provided with a bottom ring 25, and the sizes of the multiple bottom rings 25 are different. The bottom of the bottom ring 25 is provided with a T-shaped slot 26 used in conjunction with the base 24. When the multi-head electric ceramic stove body 2 is subjected to an aging test, the multi-head electric ceramic stove body 2 is first placed in the placement slot on the test bench 1, and then the test dish 3 is placed on the upper part of the microcrystalline board on the multi-head electric ceramic stove body 2, and a proper amount of oil or water is added to the test dish 3. At this time, the bottom of the base 24 contacts the upper part of the microcrystalline board, and then the test mechanism 5 is used to collide and push the test dish 3, so that the base 24 collides and rubs the microcrystalline board on the multi-head electric ceramic stove body 2, and then the collision and friction test of the microcrystalline board on the multi-head electric ceramic stove body 2 can be performed. By rotating the bottom ring 25 so that the bottom end of the bottom ring 25 is in the same horizontal plane as the base 24, the size of the contact surface with the microcrystalline board during the collision and friction tests can be changed, so that the test results can be more sufficient.

[0039] See also Figure 4 The calibration component 51 includes two rotating rods 511 rotatably arranged inside the shell 4 and symmetrically distributed front and back. The right sides of the two rotating rods 511 are movable and penetrate the shell 4 and are connected through a pulley assembly. A motor 1 512 is fixedly arranged on the upper left end of the inner side of the shell 4. The output shaft of the motor 1 512 is connected to the left end of one of the rotating rods 511. Two pull ropes 513 symmetrically distributed left and right are fixedly arranged on the circumferential outer wall of the rotating rod 511.

The bottom end of the pull rod 514 is connected to a collision ball 515 through a ball joint, and the collision ball 515 is located on the inner side of the test dish 3.

[0040] In order to improve the collision effect on the test dish 3, after the test dish 3 is placed on the upper part of the microcrystalline plate on the multi-head electric ceramic stove body 2, the motor 1 512 works and can simultaneously drive the two rotating rods 511 to rotate synchronously in the same direction through the cooperation of the pulley assembly. The rotation of the rotating rod 511 can drive the collision ball 515 to move upward or downward through the cooperation of the pull rope 513 and the pull rod 514, so that the bottom end of the collision ball 515 contacts the inner bottom end of the test dish 3. At this time, the motor 1 512 stops working to ensure that the moving height of the collision ball 515 is the same during each test, thereby further improving the collision effect on the test dish 3.

[0041] See also Figure 2 and Figure 8 The driving mechanism 6 includes a mounting seat 61 disposed at the upper right end of the housing 4, a motor 2 62 is disposed at the bottom end of the mounting seat 61, a disc 63 is rotatably disposed on the upper part of the mounting seat 61, and the bottom end of the disc 63 is connected to the output shaft of the motor 2 62, a connecting rod 1 64 is rotatably disposed at the upper end surface of the disc 63, a connecting rod 2 65 is rotatably disposed at one end of the connecting rod 1 64 away from the disc 63, and one end of the connecting rod 2 65 away from the connecting rod 1 64 movably penetrates the inner side of the housing 4.

[0042] See also Figure 2 , Figure 5 and Figure 6The collision assembly 52 includes a transverse plate 521 fixedly arranged inside the shell 4, and tooth plates 522 are slidably arranged on the front and rear sides of the upper part of the transverse plate 521, and the end of the second connecting rod 65 away from the first connecting rod 64 is connected to the outer side of the front tooth plate 522, and the two tooth plates 522 are provided with rectangular openings 523 on the sides away from each other, and control buttons 524 are fixedly arranged on the left and right sides of the rectangular opening 523, and an inclined plate 525 is fixedly arranged at the center of the rectangular opening 523, and a lifting plate 526 is slidably arranged on the inclined plate 525, and the top end of the lifting plate 526 passes through the shell 4 and is slidably connected to the shell 4, and a U-shaped plate 527 is fixedly arranged on the side of the lifting plate 526 away from the inclined plate 525. The upper left and right sides of the U-shaped plate 527 are provided with wire openings 5271, and an electromagnet 1 5272 used in conjunction with the control button 524 is fixedly arranged in the wire opening 5271. A spring 1 5273 is fixedly arranged on the side of the wire opening 5271 away from the electromagnet 1 5272, and a magnetic block 1 5274 used in conjunction with the electromagnet 1 5272 is fixedly arranged on the end of the spring 1 5273 away from the wire opening 5271. The bottom end of the pull rope 513 passes through the wire opening 5271 and is located between the electromagnet 1 5272 and the magnetic block 1 5274. The pull rope 513 can be lifted by the collision assembly 52, and then the collision ball 515 can be used to collide with the test dish 3 during the process of loosening the pull rope 513, so as to evaluate the structural integrity and durability of the microcrystalline plate when subjected to the pressure generated by the collision inside the test dish 3, and whether cracks, breakage or other forms of damage will occur.

[0043] In order to improve the collision test effect on the microcrystalline plate, as mentioned above, after the position of the collision ball 515 is adjusted, the lifting plate 526 on the front side tooth plate 522 is in contact with the control button 524 near the lifting plate 526, and the electromagnet 1 5272 is in a working state and will magnetically adsorb the magnetic block 1 5274, so that the pull rope 513 can be clamped by the electromagnet 1 5272 and the magnetic block 1 5274; then when the test is carried out, the motor 2 62 works to drive the disc 63 to rotate, the rotation of the disc 63 drives the connecting rod 1 64 to rotate, and the rotation of the connecting rod 1 64 drives the connecting rod 2 65 to move back and forth left and right, so that the movement of the connecting rod 2 65 can pull the tooth plate 522 on the front side to move back and forth left and right, and when the tooth plate 522 on the front side moves to the right, the inclined plate 525 can bring The lifting plate 526 is moved upward stably, and the lifting plate 526 moves upward to drive the U-shaped plate 527 to move upward. The upward movement of the U-shaped plate 527 can pull the pull rope 513 to move upward, thereby driving the collision ball 515 to move upward, and after the tooth plate 522 located on the front side moves to a specified distance, the lifting plate 526 just contacts the control button 524 located on the left side, so that the electromagnet 1 5272 stops working. At this time, the adsorption force on the magnetic block 1 5274 disappears, and then the spring 1 5273 can be used to drive the magnetic block 1 5274 away from the electromagnet 1 5272. At this time, the pull rope 513 is no longer clamped, and the collision ball 515 can move downward by its own gravity to perform irregular collision with the inner bottom end of the test dish 3, thereby improving the collision test effect on the microcrystalline plate.

[0045] In order to improve the friction resistance test effect of the microcrystalline board, as mentioned above, when the tooth plate 522 located on the front side reciprocates left and right, it can drive the gear 532 to rotate reciprocally. The gear 532 can make the two tooth plates 522 move synchronously in opposite directions, and the four collision balls 515 can be driven to move at the same time, so that multiple groups of tests can be carried out synchronously; and the reciprocating rotation of the gear 532 will also drive the vertical rod 531 to rotate reciprocally, and the reciprocating rotation of the vertical rod 531 drives the connecting plate 533 to rotate reciprocally, and the reciprocating rotation of the connecting plate 533 can drive the push ring 535 to move reciprocally through the connecting rod 534, so that the push ring 535 can be used to push the test dish 3, so that the base 24 moves irregularly on the microcrystalline board to rub the microcrystalline board, thereby improving the friction resistance test effect of the microcrystalline board.
