Specific implementation manners

[0022] The following will specifically describe the implementation manners of the present invention in detail, so as to fully understand how the present invention uses technical means to solve technical problems and the implementation process of achieving technical effects and implement accordingly.

[0023] Embodiment: As Figures 1 to 7 shown, a ceramic product surface engraving mechanism includes: Frame 1; Two fixed seats 2, provided on the frame 1, and an engraving component 3 is provided above the fixed seat 2; Rotating disk 4, provided on the top of the fixed seat 2 for carrying ceramic products; Clamping assembly 5, provided on one side of the fixed seat 2 for fixing ceramic products; The driving motor 6 is arranged on one side of the fixed seat 2. A main transmission shaft 61 is provided at the output end of the driving motor 6. The main transmission shaft 61 drives the rotating disk 4 and the clamping assembly 5 respectively through a shunt transmission component 62. The shunt transmission component 62 includes a first electromagnetic clutch 621 and a second electromagnetic clutch 622. The first electromagnetic clutch 621 is arranged on the transmission path between the main transmission shaft 61 and the rotating disk 4 for controlling the power on and off of the rotating disk 4. The second electromagnetic clutch 622 is arranged on the transmission path between the main transmission shaft 61 and the clamping assembly 5 for controlling the power on and off of the clamping assembly 5; The X-axis adjustment rail 7 is arranged below the fixed seat 2. An adjustment plate 71 is arranged on the X-axis adjustment rail 7, and the fixed seat 2 is arranged on the adjustment plate 71; The controller 8 is electrically connected to the driving motor 6, the first electromagnetic clutch 621, the second electromagnetic clutch 622 and the X-axis adjustment rail 7, and is configured to: control the independent engagement and separation of the first electromagnetic clutch 621 and the second electromagnetic clutch 622. When the first electromagnetic clutch 621 is engaged and the second electromagnetic clutch 622 is separated, control the adjustment plate 71 to the first working position so that the rotating disk 4 is located below the engraving component 3. When the first electromagnetic clutch 621 is separated and the second electromagnetic clutch 622 is engaged, control the adjustment plate 71 to the second working position so that the clamping assembly 5 is located below the engraving component 3.

[0024] Wherein, the shunt transmission component 62 further includes a first bevel gear 623 sleeved on the main transmission shaft 61, a driven shaft 624 arranged below the rotating disk 4, and a second bevel gear 625 arranged at the lower end of the driven shaft 624 and meshing with the first bevel gear 623. The first electromagnetic clutch 621 is arranged on the driven shaft 624, and the second electromagnetic clutch 622 is arranged on the main transmission shaft.

[0025] The clamping assembly 5 includes a mounting frame 51, a fixed clamping jaw 52 fixedly arranged at one end of the mounting frame 51, and a movable clamping jaw 53 movably arranged at the other end of the mounting frame 51. Both the fixed clamping jaw 52 and the movable clamping jaw 53 include a clamping seat 54, a multi-stage semi-circular clamping block 55 and a plurality of clamping strips 56. The clamping seat 54 is slidably connected to the semi-circular surface of the first-stage semi-circular clamping block 551. The semi-circular surfaces of the upper-stage semi-circular clamping block and the lower-stage semi-circular clamping block are slidably connected. The number of semi-circular clamping blocks at each level increases gradually. At least two of the clamping strips 56 are slidably arranged on the side of each last-stage semi-circular clamping block 552 away from the semi-circular surface.

[0026] In this embodiment, both the fixed clamping jaw 52 and the movable clamping jaw 53 include three-stage semi-circular clamping blocks. Two clamping strips 56 are arranged on the last-stage semi-circular clamping block 552, and the form of the sliding connection is a sliding connection through a dovetail groove.

[0027] The top of each clamping strip 56 is higher than each final-stage semi-circular clamping block 552, so as to have a longer clamping height to obtain a more stable clamping effect, which can reduce the main body material of the clamping assembly 5. Each clamping strip 56 is provided with a buffer sleeve 561. Each buffer sleeve 561 is made of rubber material. Hollowing can also be provided on the rubber to increase the friction and deformation ability. Each buffer sleeve 561 is arranged on the upper half of each clamping strip 56, and the outer diameter of the buffer sleeve 561 is the same as the diameter of the lower half of each clamping strip 56.

[0028] The mounting frame 51 is provided with a sliding groove 511. A sliding block 512 and a lead screw 513 are arranged in the sliding groove. The sliding block 512 is connected to the movable clamping jaw 53. The lead screw 513 passes through one end of the mounting frame 51 and penetrates to the other end. One end of the lead screw 513 is provided with an adjusting motor 514. The adjusting motor 514 is electrically connected to the controller 8. The controller 8 is further configured to: adjust the distance between the fixed clamping jaw 52 and the movable clamping jaw 53 based on the inner diameter or outer diameter of the ceramic product. The controller 8 automatically calculates the clamping distance according to the input inner diameter / outer diameter data, reduces the manual adjustment time, and avoids deformation and damage of thin-walled workpieces.

[0029] A Y-axis adjusting rail 9 is arranged below the X-axis adjusting rail 7. The X-axis adjusting rail 7 is slidably arranged on the Y-axis adjusting rail 9, and the two are arranged orthogonally.

[0030] The lettering component 3 includes a Z-axis adjusting rail 31, a mounting block 32 slidably arranged on the Z-axis adjusting rail 31, a high-frequency electric spindle 33 arranged on the side wall of the mounting block 32, and a lettering tool 34 mounted below the high-frequency electric spindle 33.

[0031] Among them, the controller 8 is an industrial controller equipped with a motion control card. The X / Y / Z-axis adjusting rails all adopt linear guide rails, which can be purchased on the market and will not be elaborated here. The states of the first and second electromagnetic clutches are switched according to the processing stage. The motion control card is connected to the drive motor, X / Y / Z-axis adjusting rails and the high-frequency electric spindle 33 through the EtherCAT bus.

[0032] An air-cooling sleeve 35 is arranged outside the high-frequency electric spindle 33, and low-temperature nitrogen gas at 10 °C is introduced. The air-cooling sleeve 35 is connected to a negative-pressure dust removal pipe 36. The negative-pressure dust removal pipe 36 is externally connected to a centrifugal fan (not shown in the figure). The low-temperature nitrogen gas reduces the heat generated by the high-speed rotation of the high-frequency electric spindle 33 and carries the cuttings into the negative-pressure dust removal pipe 36, and pumps the airflow containing cuttings into the filtration system (such as a bag filter or a cyclone separator).

[0033] Among them, an air flow outlet 351 connected to a negative pressure dust removal pipe 36 is arranged at the top of the air-cooling sleeve 35, a diversion port 352 is arranged at the bottom of the air-cooling sleeve 35, and an air flow inlet 353 is arranged on the side wall of the air-cooling sleeve 35. The air flow inlet 353 intakes air obliquely upward to cover the chip generation area. A spiral guide plate 354 is arranged inside the air-cooling sleeve 35 to guide nitrogen to flow along the axial direction of the high-frequency electric spindle 33, increasing the residence time of nitrogen in the air-cooling sleeve 35 and enabling it to fully exchange heat with the high-frequency electric spindle 33. When using low-temperature nitrogen at 5°C, the setting of the spiral guide plate 354 can be cancelled.

[0034] Although the present invention has been specifically shown and described in conjunction with the preferred embodiments, those skilled in the art should understand that various changes can be made to the present invention in terms of form and details without departing from the spirit and scope of the present invention defined by the appended claims, and all of them fall within the protection scope of the present invention.
