Technical Field

[0001] This utility model relates to the technical field of electric furnace manufacturing equipment, and in particular to a furnace head ceramic plug clamping fixture. Background Technology

[0002] Electric stoves utilize the properties of plasma, using high-voltage electricity to break down air and create thermal plasma, converting electrical energy into heat energy, and ultimately obtaining a thermal plasma beam with ideal functions. This thermal plasma beam, with flame-like characteristics, heats cookware for cooking. Because electricity is used as the direct energy input, the mains voltage needs to be boosted to 10KV to generate the plasma beam. Therefore, each electrode needle in the burner head needs to be insulated with a ceramic plug. The bonding quality of the ceramic plug directly affects the lifespan and stability of the stove. Existing burner head ceramic plugs have poor bonding strength consistency, making it difficult to achieve a stable bonding effect after bonding. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a furnace head ceramic plug clamping fixture in view of the above-mentioned technical deficiencies. The fixture uses a base plate, a limiting plate and a pressure plate to clamp the ceramic plug in the furnace head, which solves the problem of poor bonding strength consistency of existing furnace head ceramic plugs and difficulty in achieving stable bonding effect after bonding.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: a ceramic plug pressing fixture for a furnace head includes a bottom plate, a limiting plate on the upper part of the bottom plate, a limiting groove in the limiting plate for limiting the position of the furnace head, a support column between the bottom plate and the limiting plate, a guide column on one side of the limiting groove, the guide column being fixed to the upper part of the limiting plate, a pressure plate passing through the upper part of the guide column, multiple ceramic plugs and electrode needles in the furnace head, a through hole in the pressure plate corresponding to the position of the ceramic plug, a pressure plug in the through hole, the lower surface of the pressure plug pressing against the upper part of the ceramic plug, a through hole in the center of the pressure plug corresponding to the position of the electrode needle, and a pressure regulating device on the upper side of the pressure plug.

[0005] To further optimize this technical solution, the pressure regulating device includes a spring and a screw sleeve. The inner wall of the upper part of the through hole is provided with an internal thread. The screw sleeve is threaded to the internal thread through the external thread on the outside. The spring is abutted between the screw sleeve and the pressure plug. The bottom edge of the through hole is provided with an annular limiting platform. The ceramic plug passes through the limiting platform. The pressure plug is set on the upper part of the limiting platform. The inner diameter of the limiting platform is smaller than the outer diameter of the pressure plug.

[0006] To further optimize this technical solution, an internal hexagonal hole with an internal hexagonal cross-section is provided at the center of the threaded sleeve.

[0007] To further optimize this technical solution, the upper surface of the plunger is provided with an annular limiting protrusion, and the bottom end of the spring is sleeved on the outside of the limiting protrusion.

[0008] To further optimize this technical solution, the upper surface of the limiting plate is provided with multiple clearance grooves.

[0009] To further optimize this technical solution, a bearing surface is provided on the upper surface of the pressure plate.

[0010] Compared with the prior art, this utility model has the following advantages: 1.

[0015] Combination Figures 1 to 3 As shown, a ceramic plug clamping fixture for a burner head includes a base plate 1 at the bottom, a limiting plate 2 on the upper part of the base plate 1, a limiting groove 21 inside the limiting plate 2 for limiting the position of the burner head 3, the limiting groove 21 for limiting the position of one end of the outer wall of the burner head 3, and a plurality of clearance grooves 22 on the upper surface of the limiting plate 2. The clearance grooves 22 are used to avoid protruding parts such as mounting and fixing columns at the bottom of the burner head 3. A support column 12 is provided between the base plate 1 and the limiting plate 2, and a guide column 4 is provided on one side of the limiting groove 21. The guide column 4 is fixed to the upper part of the limiting plate 2, and a pressure plate 5 is slidably inserted through the upper part of the guide column 4. The upper surface of the pressure plate 5 is provided with a bearing surface 54.

[0016] The burner head 3 is provided with multiple ceramic plugs 30 and electrode needles 31. The ceramic plugs 30 are coaxially sleeved on the outer side of the bottom end of the electrode needles 31. The ceramic plugs 30 have the effect of fixing and insulating the electrode needles 31. The pressure plate 5 is provided with a through hole 50 at the position corresponding to the ceramic plugs 30. A pressure plug 51 is provided in the through hole 50. The lower surface of the pressure plug 51 is pressed against the upper part of the ceramic plug 30. The center of the pressure plug 51 is provided with a through hole 510 at the position corresponding to the electrode needles 31. A pressure regulating device is provided on the upper side of the pressure plug 51.

[0017] Combination Figure 3 As shown, the pressure regulating device includes a spring 52 and a screw sleeve 53. The screw sleeve 53 has an internal hexagonal hole 530 at its axial center. This internal hexagonal hole 530 not only prevents the screw sleeve 53 from interfering with the position of the electrode needle 31, but also allows for easy adjustment of the clamping force by rotating the screw sleeve 53 with a hexagonal wrench, making it convenient to use. An internal thread 501 is provided in the inner wall of the upper part of the through hole 50. The screw sleeve 53 is threaded to the internal thread 501 through its external thread. The spring 52 is positioned between the screw sleeve 53 and the pressure plug 51. The upper surface of the pressure plug 51 has an annular limiting protrusion 511, and the bottom end of the spring 52 is fitted onto the outside of the limiting protrusion 511.

[0018] The bottom edge of the through hole 50 is provided with an annular limiting platform 502. The ceramic plug 30 is inserted into the limiting platform 502. The pressure plug 51 is located on the upper part of the limiting platform 502. The inner diameter of the limiting platform 502 is smaller than the outer diameter of the pressure plug 51, which can restrict the pressure plug 51 on the upper side of the limiting platform 502 and prevent the pressure plug 51 from sliding out.

[0019] In use, the ceramic plug 30 and electrode needle 31 are first bonded and fixed in the burner head 3. Before they are fully cured, the burner head 3 is placed in the limiting groove 21 of the limiting plate 2. Then, the pressure plate 5 is aligned with the guide post 4 and placed on the upper part of the burner head 3, so that the electrode needle 31 passes through the corresponding through hole 50. After the electrode needle 31 passes through the through hole 510, the pressure plug 51 is pressed against the upper surface of the ceramic plug 30. The limiting platform 502 limits the horizontal position of the ceramic plug 30 on the one hand, and prevents the pressure plug 51 from popping out under the action of the spring 52 on the other hand. The bearing surface 54 of multiple sets of burner head ceramic plug pressing fixtures can share the same weight to press down simultaneously, completing the pressing of multiple sets of pressure plates 5. The screw sleeve 53 can be rotated by a hex wrench to adjust the compression degree of the spring 52, thereby adjusting the pressing force of the pressure plug 51 in each through hole 50. It can adapt to the bonding of different types of ceramic plugs 30, ensuring stable bonding strength and good adaptability.
