[0026] A worm 101 and a worm wheel 102 are respectively provided inside the fixed base 1 on one side below the rotating base 2. The worm 101 is rotatably connected to the inside of the fixed base 1 through the output end of the servo motor, and the worm wheel 102 is meshedly connected to one end of the worm 101. The worm wheel 102 is welded to the bottom of the rotating base 2 through a shaft running through its axis.

[0027] The internal rotation of the limit assembly 3 is connected to a reverse screw 301, and the outer wall of the reverse screw 301 is threadedly connected to a reverse nut 302. One end of the reverse nut 302 is bolted to a protective side plate 303. The protective side plate 303 is located between the rotating base 2 and the rubber backing plate 6. The protective side plate 303 is glued to a first rubber roller 305 through a spring 304 opened on its inner wall.

The interior of the mounting frame 1102 is connected to the grinding wheel 1103 by bolts, and the two ends of the grinding wheel 1103 are rotatably connected to the second rubber roller 1104.

[0030] In this embodiment, Figure 2 As shown, the worm wheel 102 forms a transmission structure through the worm 101, and the rotating base 2 forms a rotating structure on the surface of the fixed base 1 through the worm wheel 102, and the axis points of the rotating base 2 and the rubber backing plate 6 are located on the same vertical center line; the structure of the rotating base 2 can prevent the operator from directly contacting the polishing workpiece, thereby improving the safety of the working environment and effectively reducing the potential risk of work-related injuries. The transmission structure of the worm wheel 102 and the worm 101 is used to achieve the rotation of the rotating base 2 of the device workpiece, which can achieve smoother deceleration and torque transmission, so that the workpiece can be polished in a more uniform and stable environment, reducing the possibility of shaking, thereby ensuring the uniformity and consistency of the polishing effect while ensuring safety, thereby improving the processing quality.

[0031] In this embodiment, Figure 1 and Figure 2As shown, the rubber disc 6 forms a lifting structure above the rotating base 2 through the first hydraulic cylinder 4, and the first hydraulic cylinder 4 is electrically connected to the hydraulic controller; the rubber disc 6 can be driven by the first hydraulic cylinder 4 to press against the inner bottom wall of the workpiece, effectively fix the position of the workpiece on the rotating base 2, reduce movement and shaking during processing, and thus improve the processing accuracy and consistency, and the rubber disc 6 is a soft material with good protective properties, reducing scratches and damage to the surface of the ceramic blank. At the same time, its axial position with the rotating base 2 can ensure the symmetry of the workpiece during processing and improve the accuracy of workpiece processing. Although the unfired ceramic blank has a certain hardness, to avoid damage to it, by adding a hydraulic controller (model PCM701K), the operator can control the pressure more accurately to ensure that the applied pressure is moderate, which can both protect the workpiece and provide sufficient fixing force.

[0032] In this embodiment, Figure 1 and Figure 5 As shown, the reverse nut 302 forms a transmission structure through the reverse screw 301, and the protective side plates 303 form relative movement through the reverse nut 302, and the protective side plates 303 are symmetrically distributed about the vertical center line of the axis point of the rotating base 2, and the first rubber roller 305 forms an elastic reset structure through the spring 304; a limit component 3 is added to the outside of the workpiece at the contact of the rubber disc 6, which can be used to fit the outer wall of the workpiece but not to achieve clamping, further reducing the possibility of instability caused by shaking of the workpiece due to rotation, and its adjustment structure can adapt to workpieces of different specifications, and when the workpiece rotates, the first rubber roller 305 fitted on its surface can make its rotation process more stable, provide it with certain support, and then maintain absolute stability during front end grinding, the elastic properties of the spring 304 play a certain buffering role, avoiding the first rubber roller 305 from causing hard collision with the workpiece surface, and at the same time can adaptively fit according to the shape of the outer wall of the workpiece.

[0033] In this embodiment, Figure 1 , Figure 3 and Figure 4As shown, the mobile push frame 9 forms a horizontal transmission structure on the surface of the transverse support rod 10 through the second hydraulic cylinder 7 and the spring pneumatic rod 8, and the lifting nut 903 forms a vertical transmission structure through the lifting screw 901, and the lifting nut 903 is located at one end of the outside of the mobile push frame 9 and is slidably connected to the outer wall of the vertical support rod 902; the equipment used for grinding is driven and controlled by the mobile push frame 9, and the extension and retraction of the mobile push frame 9 is not only convenient for loading and unloading workpieces, but also convenient for advancing the grinding equipment according to the irregular outer wall of the workpiece surface, and the second hydraulic cylinder 7 serves as an active driving source, the upper and lower groups of spring pneumatic rods 8 (model JBL-YQ) and the sliding structure between the mobile push frame 9 and the transverse support rod 10 all provide relatively stable support for the transmission of the mobile push frame 9, so that the grinding parts on the surface of the front end bearing base 11 can always maintain a consistent contact pressure when contacting with the workpiece, thereby ensuring the uniformity of the grinding effect and the quality of the workpiece surface.

[0034] In this embodiment, Figure 3 and Figure 4 As shown, the bearing base 11 forms a telescopic structure on the surface of the rotating base 2 through the mobile push frame 9, and the bearing base 11 forms a lifting structure on the surface of the mobile push frame 9 through the lifting nut 903, and the mounting frame 1102 forms an elastic reset structure through the compression spring 1101; the workpiece rotating structure and the lifting structure of the bearing base 11 can realize all-round automatic grinding of the workpiece, which is safer than hand-held contact grinding equipment, and its automatic operation structure can always maintain a stable speed and pressure, thereby realizing a more consistent grinding structure. Compared with manual operation, it can better control the grinding parameters and provide product consistency. At the same time, the structure of the second rubber roller 1104 helps to share the pressure for the grinding wheel 1103, maintain the stability of the contact between the grinding wheel 1103 and the workpiece, and also plays a guiding role, so that when the grinding wheel 1103 contacts the workpiece, the movement of the workpiece is smoother, and the compression spring 1101 provides a certain elasticity for the two groups of parts, so that they can adaptively fit the outer wall of the workpiece without being restricted by the conditions of the workpiece shape.

[0035] The use method and advantages of the utility model: When the daily ceramic blank edge grinding equipment is used, the working process is as follows:

[0036] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, first, the workpiece to be polished is placed on the surface of the rotating base 2, and the connecting rod 5 is driven by the first hydraulic cylinder 4 to drive the rubber disc 6 to apply pressure to the inner bottom wall of the workpiece. The first hydraulic cylinder 4 is electrically connected to a digital hydraulic controller, which can effectively avoid the problem of excessive pressure causing damage to the workpiece. After the initial fixation is completed, the servo motor of the limit assembly 3 is driven to control the rotation of the reverse screw 301. While the two reverse nuts 302 rotate respectively, the two external protective side plates 303 are driven to approach the workpiece in a relatively moving structure. The several first rubber rollers 305 on the surface of the protective side plates 303 only need to fit the edge of the workpiece, and there is no need to achieve the purpose of clamping. After the fixation of the limit assembly 3 is completed, it is driven by the second hydraulic cylinder 7. When the mobile push frame 9 moves forward, the corresponding spring gas pressure rod 8 is stretched at the same time. At the same time, the slider fixed under the mobile push frame 9 slides on the surface of the transverse support rod 10 accordingly, so that the structure used for polishing on the surface of the bearing base 11 fits on The surface of the workpiece, after the power is turned on, the worm 101 is rotated by the servo motor and then the worm wheel 102 rotates, while driving the rotating base 2 on the top to rotate, the rubber disc 6 is correspondingly attached to the inner bottom wall of the workpiece and rotates at the bottom of the connecting rod 5, and the workpiece is attached between the protective side plates 303 and rotates, and the first rubber roller 305 on the inner wall of the protective side plates 303 helps to ensure the smoothness of the workpiece rotation process and provide stability for its rotation. When the workpiece contacts the fixed grinding wheel 1103 during rotation, the grinding wheel 1103 will grind the burrs on the surface. At the same time, when the workpiece completes a circle of rotation, the transmission structure of the lifting screw 901 and the lifting nut 903 can enable the bearing base 11 to grind from the workpiece surface to the bottom through the lifting movement. Since the outer wall of the ceramic blank is mostly curved, the bearing base 11 uses the second hydraulic cylinder 7 and its own elastic structure to make the structure of the surface of the mounting frame 1102 adaptively contact with the outer wall of the workpiece, thereby improving the effectiveness of grinding.

[0037] The above shows and describes the basic principle, main features and advantages of the utility model. Technical staff in this industry should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model. Without departing from the spirit and scope of the utility model, the utility model will have various changes and improvements, which fall within the scope of the utility model to be protected.
