Description

Technical Field

[0001] The utility model relates to the technical field of deep processing of ceramic tiles, in particular to a heat-insulating grinding head. Background Art

[0002] At present, the structure of mainstream grinding head products on the market is mainly one-piece forging or casting (see attached Figure 1 ), the structural strength is well guaranteed. However, when the edge grinding head is in use, the motor is often in high-speed operation (maximum speed can reach 5000rpm), which makes the bearings heat up during operation, and a lot of heat is generated during the grinding wheel cutting process. The integrated grinding wheel mounting shaft structure inevitably transfers the grinding heat directly to the bearing through the shaft structure, causing the bearing temperature to rise. Excessive temperature will cause the bearing to loosen and become unstable, and the running accuracy of the bearing cannot be guaranteed. The life of the bearing is greatly shortened, and the heat transferred to the motor will cause damage to the motor, ultimately affecting the service life and processing accuracy of the edge grinding head.

[0025] In order to make the purpose, technical solutions and advantages of the utility model clearer, the utility model will be further described in detail below with reference to the accompanying drawings.

[0026] See also Figure 1 , 2 An embodiment of the utility model provides a thermal insulation grinding head, including a grinding wheel mounting assembly for mounting a grinding wheel and a driving shaft 1 for driving the grinding wheel mounting assembly to rotate, wherein the grinding wheel mounting assembly is arranged at one end of the driving shaft 1; wherein the grinding wheel mounting assembly includes a mounting plate 2 for connecting and mounting a grinding wheel and a thermal insulation transition plate 3 for driving the mounting plate 2 to rotate, wherein the thermal insulation transition plate 3 is located between the mounting plate 2 and the driving shaft 1; the thermal insulation transition plate 3 is connected to the driving shaft 1 so as to be driven by the rotation of the driving shaft 1.

[0027] Specifically, a spacer connector is connected between the mounting plate 2 and the thermal insulation transition plate 3, so that a preset thermal insulation gap a is left between the mounting plate and the thermal insulation transition plate 3. By setting the thermal insulation gap a, the contact heat transfer amount between the mounting plate 2 and the thermal insulation transition plate 3 can be greatly reduced, thereby further improving the thermal insulation performance.

[0030] Correspondingly, the spacer 5 and the heat-insulating transition plate 3 are both made of heat-insulating materials, such as polymer heat-insulating materials PE, POM, PEEK, etc.

[0031] Furthermore, since the grinding disc will generate high-frequency vibration during the grinding process, in order to improve the connection stability between the mounting disc 2 and the heat-insulating transition disc 3 and reduce its influence on related parts on the drive shaft 1, such as bearings, etc., the mounting disc 2 and the heat-insulating transition disc 3 are both provided with a spacing positioning groove B for the spacer 5 to be embedded. Therefore, the linkage force between the mounting disc 2 and the heat-insulating transition disc 3 needs to be driven by the spacer 5, so the spacer 5 can be made of a heat-insulating material with a certain elasticity, such as PE.

[0032] The mounting plate 2 is provided with a plurality of grinding wheel mounting holes 21 for mounting grinding wheels, and the thermal insulation transition plate 3 is provided with avoidance openings 31 corresponding to the grinding wheel mounting holes, so as to avoid affecting the installation of the grinding wheel on the mounting plate 2 while reducing the corresponding heat transfer area between the mounting plate 2 and the thermal insulation transition plate 3.

[0033] In order to facilitate the positioning and installation of the thermal insulation transition disk 3, a driving head 11 is provided at one end of the driving shaft 1 for connecting the thermal insulation transition disk 3, and the thermal insulation transition disk 3 is provided with a positioning groove 32 adapted to the driving head 11 for the driving head 11 to be inserted.

[0034] For the installation of the grinding wheel, the mounting plate 2 is provided with a grinding wheel positioning hole 22, which is connected to the thermal insulation gap a to improve the air flow at the thermal insulation gap a, thereby avoiding excessive heat accumulation at the thermal insulation gap a. The edge of the grinding wheel positioning hole 22 extends outward to form a positioning ring 23 for the grinding wheel sleeve to be installed.

[0035] The drive shaft 1 is provided with a bearing 6, and the drive shaft 1 is provided with a step surface 12 for positioning and installing the bearing, and at least one bearing is arranged on the step surface 12; a dust cover 7 is provided between the bearing on the step surface 12 and the drive head 11 to seal and protect the bearing 6 and prevent dust from entering.

[0036] The dust cover 7 and the drive shaft 1 are both provided with a plurality of plug-in parts 8 for interlocking with each other, and adjacent plug-in parts 8 form plug-in grooves 81 for insertion of the plug-in parts, thereby achieving a closed connection between the dust cover 7 and the drive shaft 1 while also providing multiple sealing and dustproof protection.

[0037] The above is a preferred embodiment of the present invention. It should be pointed out that a person skilled in the art can make several improvements and modifications without departing from the principle of the present invention. These improvements and modifications are also considered to be within the protection scope of the present invention.
