Description

Technical Field

[0001] The invention relates to the technical field of electric ceramic stove detection, and in particular to an electric ceramic stove component performance detection device. Background Art

[0002] An electric ceramic stove is a cooking appliance that uses the principle of resistance heating and is widely used in home kitchens and commercial kitchens. An electric ceramic stove is mainly composed of a heating plate, a microcrystalline plate, an electronic control system, a temperature control system and a stove body.

[0003] Among them, the ceramic heating plate is one of the core components of the electric ceramic stove. Its performance directly affects the heating efficiency and service life of the electric ceramic stove. During the manufacturing process, the ceramic heating plate needs to undergo a series of performance tests, including electrical properties, mechanical strength properties, thermal properties and chemical properties, among which mechanical strength properties and thermal properties are the most important.

[0004] In the prior art, when testing the impact strength of a ceramic heating plate in terms of mechanical strength performance, the ceramic heating plate is usually first fixed on a test bench to ensure that it is stable and will not move. Subsequently, the impact energy, height and other relevant parameters of the test machine are set according to standard requirements. The test machine is then started to allow a heavy object to fall freely from a predetermined height to hit the ceramic heating plate, and the state of the ceramic heating plate after the impact is observed and recorded. Although this method can detect the impact strength of the ceramic heating plate, the impact position of the heavy object on the ceramic heating plate remains unchanged each time it hits the ceramic heating plate. If the thickness of the ceramic heating plate at different positions is inconsistent, the test result will be inaccurate if the impact is only performed from one point, thereby reducing the effect of the test.

The number of counterweight plates 534 placed can be adjusted accordingly to meet different force requirements, thereby improving the flexibility of the detection equipment.

[0038] See also Figure 1 , Figure 2 and Figure 5 The bottom of the lifting mechanism 52 is connected to a sliding mechanism 54 , and the sliding mechanism 54 is connected to a detection mechanism 55 .

A sliding block 543 is connected to the surface of the rectangular rod 542 through a sliding sleeve, and a threaded sleeve 544 is installed at the lower end of the sliding block 543.

[0040] See also Figure 1 , Figure 2 , Figure 5 and Figure 8The detection mechanism 55 includes a Z-shaped rod 551 whose vertical section is located on the upper side and is threadedly connected to the threaded sleeve 544. A positioning circular plate 552 is installed through the vertical section of the Z-shaped rod 551 located on the lower side. The positioning circular plate 552 is connected with a plurality of adjusting branches 553 evenly distributed from the inside to the outside. The plurality of adjusting branches 553 have the same structure but different sizes. The vertical section of the Z-shaped rod 551 located on the lower side is also connected with a limiting branch 554 located above the positioning circular plate 552.

[0041] During specific operation, the Z-shaped rod 551 is connected to the lower end of the threaded sleeve 544. Initially, the vertical section of the Z-shaped rod 551 on the lower side is coaxial with the rotating rod 51. The vertical section of the Z-shaped rod 551 on the lower side carries the positioning circular plate 552, the adjusting branch chain 553 and the limiting branch chain 554 and is located directly below the rotating rod 51.

[0042] See also Figure 2 and Figure 8 The adjusting branch chain 553 includes two lifting columns 5531 which are symmetrically distributed along the vertical section axis located at the lower side of the Z-shaped rod 551 and are slidably connected to the positioning circular plate 552. A circular ring sleeve 5532 is commonly installed at the lower ends of the two lifting columns 5531, and a downward pressure arc plate 5533 is installed at the upper ends of the lifting columns 5531.

[0044] Initially, the height of the limiting plate 5542 is lower than the height of the lower arc pressing plate 5533 at the initial position. During operation, according to the force required for detection, a corresponding number of lower arc pressing plates 5533 are pressed downward from the inside to the outside in sequence, and the lower arc pressing plates 5533 drive the annular sleeve 5532 to move downward through the lifting column 5531 until the lower end of the lower arc pressing plate 5533 contacts the upper end of the positioning circular plate 552. At this time, the lower end of the annular sleeve 5532 is flush with the lower end of the Z-shaped rod 551, thereby changing the contact area between the detection equipment and the ceramic heating plate of the electric ceramic stove, and changing The force strength of the ceramic heating plate effectively improves the applicability of the detection. Then, the limiting plate 5542 is rotated, and the limiting plate 5542 is rotated through the rotating ring 5541. The two limiting plates 5542 move to the upper ends of the multiple lower pressure arc plates 5533 on both sides that are in contact with the upper end of the positioning circular plate 552, thereby realizing the function of limiting the lower pressure arc plate 5533. At the same time, the upper end of the limiting plate 5542 also supports the lower pressure arc plate 5533 whose position has not changed, thereby preventing the lower pressure arc plate 5533 whose position has not changed during the detection process from moving downward.

[0045] See also Figure 1 and Figure 5 The electric ceramic stove assembly performance testing device also includes a placing device 6, which is arranged below the testing device 5 and is used to place the electric ceramic stove.

A limiting rod 634 is installed on the upper end of the limiting slider 632.

[0047] During specific operation, after the Z-shaped rod 551 is connected to the lower end of the threaded sleeve 544, the circular plate 61 is fixed in the working position through multiple support columns 64, and then multiple limiting rods 634 are pushed at the same time. The limiting rods 634 drive the limiting slider 632 to slide on the third guide rod 631 in the direction away from the axis of the circular plate 61 and squeeze the reset spring 633. Then, the electric ceramic stove to be tested is placed on the circular plate 61 and the blocking of the multiple limiting rods 634 is released. The multiple squeezed reset springs 633 drive the corresponding limiting sliders 632 to slide, and the limiting slider 632 drives the limiting rod 634 to move toward the electric ceramic stove. The multiple limiting rods 634 are tightly attached to the electric ceramic stove and limit it. Then, the electric ceramic stove is connected to an external power supply and started, so that the impact strength of the ceramic heating plate under different heating conditions can be measured.

[0048] See also Figure 1 and Figure 5 The electric ceramic stove component performance testing equipment also includes a lifting device 3, which is connected to the lower end of the fixed plate 1.

A circular plate 32 is commonly installed at the lower end of the inner arc surface of the plurality of connecting arc plates 31. A plurality of lifting blocks 33 evenly distributed in the circumferential direction are installed at the upper end of the circular plate 32. The lifting blocks 33 are of a right-angled triangle structure and the right-angled surface contacts the circular plate 32. The upper and lower sides of the inclined surface of the lifting blocks 33 are provided with arc transition surfaces.

[0049] See also Figure 6A sliding groove 522 is provided at one end of the vertical section of the U-shaped frame 521 close to the rotating rod 51, and a lifting block 523 is slidably connected in the sliding groove 522.

The second guide rail rod 524 is fixedly connected to the horizontal groove wall of the sliding groove 522. The upper and lower horizontal sections of the U-shaped frame 521 are respectively located on the upper and lower sides of the circular ring plate 32. A cylindrical roller 525 in a horizontal state is rotatably connected to the upper horizontal section of the U-shaped frame 521.

[0050] In specific operation, after the ceramic heating plate of the electric ceramic stove is heated up, the driving motor 2 is started, the driving motor 2 drives the rotating rod 51 to rotate, the rotating rod 51 drives the lifting block 523 to rotate, the lifting block 523 drives the U-shaped frame 521 to rotate through the second guide rail rod 524 and the sliding groove 522, the U-shaped frame 521 drives the sliding block 543 to rotate circumferentially through the two connecting plates 541 and the rectangular rod 542, the sliding block 543 drives the Z-shaped rod 551 to rotate through the threaded sleeve 544, and at the same time, the U-shaped frame 521 drives the cylindrical roller 525 to rotate on the annular plate 32, when the cylindrical roller 525 moves to the lifting block 33, the lifting block 33 guides the cylindrical roller 525, the cylindrical roller 525 moves along the inclined surface of the lifting block 33, the lifting block 33 lifts the cylindrical roller 525, the cylindrical roller 525 is forced to drive the U-shaped frame 521 to rise, and the U-shaped frame 521 is driven by the lifting block 33. The sliding block 543 is driven to rise through the two connecting plates 541 and the rectangular rod 542, and the sliding block 543 drives the Z-shaped rod 551 to rise through the threaded sleeve 544. At the same time, the U-shaped frame 521 drives multiple counterweight plates 534 to rise through the support frame 531. When the jacking block 33 is separated from the cylindrical roller 525, the multiple counterweight plates 534 move downward by their own gravity and drive the U-shaped frame 521 to move downward. The U-shaped frame 521 drives the sliding block 543 to descend through the two connecting plates 541 and the rectangular rod 542, and the sliding block 543 drives the Z-shaped rod 551 to descend through the threaded sleeve 544. The lower end of the Z-shaped rod 551 knocks the ceramic heating plate of the electric ceramic furnace, and then observes the degree of damage on the surface of the ceramic heating plate. The rotating U-shaped frame 521 drives the cylindrical roller 525 to repeatedly contact with multiple jacking blocks 33, thereby realizing the function of continuously knocking the ceramic heating plate.

[0051] See also Figure 1 , Figure 5 and Figure 6 The detection device 5 also includes a U-shaped plate 56 with an opening facing the rotating rod 51 and fixedly connected to the annular surface of the rotating rod 51.

A moving block 58 is slidably sleeved on the two first guide rods 57, and the lower end of the threaded sleeve 544 slides through the moving block 58.

[0052] See also Figure 1 , Figure 5 and Figure 7 The electric ceramic stove assembly performance detection device also includes a guiding device 4, which is connected to the lower ends of the plurality of connecting arc plates 31. The guiding device 4 includes a plurality of L-shaped arc plates 41 that are evenly distributed in the circumferential direction and correspondingly installed at the lower ends of the plurality of connecting arc plates 31.

A spiral plate 43 in the shape of an Archimedean spiral is installed on the inner ring surface of the first circular ring 42. A second circular ring 44 coaxial with the first circular ring 42 is installed at the inner end of the spiral plate 43.

[0053] During specific operation, initially, the threaded sleeve 544 is located directly above the inner end of the second ring 44 and the spiral plate 43. During detection, the rotating rod 51 also drives the moving block 58 to rotate through the U-shaped plate 56 and the first guide rod 57. The moving block 58 drives the threaded sleeve 544 to rotate, further improving the rotation stability of the threaded sleeve 544. The circumferentially rotating threaded sleeve 544 drives the Z-shaped rod 551 to move along the outer side of the second ring 44 and the side wall of the spiral plate 43. The outer side of the second ring 44 and the side wall of the spiral plate 43 guide the Z-shaped rod 551. The Z-shaped rod 551 is forced to move from the inside to the outside, and the threaded sleeve 544 is driven by the force of the Z-shaped rod 551 to gradually move toward the outside of the ceramic heating plate. The threaded sleeve 544 is driven by the force to drive the moving block 58 to slide on the two first guide rods 57, thereby changing the contact position between the lower end of the Z-shaped rod 551 and the ceramic heating plate. At the same time, the driving motor 2 continues to work, so that it continues to move in a circular motion after moving outward for a certain distance each time, thereby realizing the function of knocking on the ceramic heating plates at different positions, ensuring that the entire ceramic heating plate can be tested, thereby improving the detection effect.

[0054] The threaded sleeve 544 also drives the sliding block 543 to slide on the rectangular rod 542. The rectangular rod 542 is fixedly connected to the U-shaped frame 521 through two connecting plates 541, ensuring that the threaded sleeve 544 can move outward while also moving circumferentially and up and down, thereby ensuring the normal operation of the detection mechanism 55. When the Z-shaped rod 551 moves to the outer end of the spiral plate 43, the drive motor 2 is turned off, and the degree of damage to the ceramic heating plate is observed. If the ceramic heating plate is not damaged, the Z-shaped rod 551 is separated from the threaded sleeve 544, and the number of counterweight plates 534 is increased again and the contact area between the detection mechanism 55 and the ceramic heating plate is changed. Then, the threaded sleeve 544 is pushed to the initial position, and then the Z-shaped rod 551 is reconnected to the threaded sleeve 544, and the previous ceramic heating plate detection steps are repeated until the ceramic heating plate is broken or the force applied during the detection reaches the maximum value of the detection standard, and the detection results are recorded. Finally, the power of the electric ceramic stove is turned off and the detection is completed.
