Description

Technical Field

[0001] The invention relates to a polishing machine tool, in particular to an asphalt grinding head and a polishing machine. Background Art

[0002] The emergence of modern optical processing technology, represented by computer-controlled optical surface forming technology, has improved the efficiency of optical processing. However, due to the characteristics of the technology itself and complex factors in the processing process, intermediate frequency surface errors will inevitably occur during the processing. For imaging optical systems, intermediate frequency errors will cause light to scatter at small angles and reduce image contrast. For high-power laser systems, intermediate frequency errors will cause bright spots to widen and reduce brightness.

[0003] In order to remove the mid-frequency error, a common method is to use an asphalt disc combined with abrasives to smooth the mirror surface. During the smoothing process, the asphalt surface temperature drops and hardens, and it is easy to break during the smoothing process, resulting in scratches on the mirror surface. Currently, some asphalt dough heads with heating functions have appeared, which can heat the asphalt disc to soften the asphalt disc, but such asphalt discs are usually one-piece structures, which are difficult to adjust adaptively according to different workpiece processing, and the heating effect of the asphalt disc is poor. Therefore, there is an urgent need for an asphalt disc with stronger versatility and better heating effect. Summary of the invention

[0004] The purpose of the present invention is to provide an asphalt grinding head and a polishing machine to solve one or more technical problems existing in the prior art and at least provide a beneficial choice or create conditions.

[0005] The solution of the present invention to solve its technical problem is: An asphalt grinding head comprises: a connecting plate, a heating groove is arranged on the top side of which; an asphalt processing plate, which is detachably connected to the bottom side of the connecting plate; a heat-insulating plate, a heating source is detachably connected to the bottom side of which, the heat-insulating plate is detachably connected to the top side of the connecting plate, and the heating source is located in the heating groove.

[0006] This technical solution has at least the following beneficial effects: when in use, the heat-insulating disk is connected to an external polishing device, and the asphalt processing disk for mirror processing is installed on the bottom side of the connecting disk. When the mirror processing is required, the heating source works, and the heat generated is transmitted to the asphalt processing disk through the connecting disk, so that the hardness of the asphalt processing disk is reduced. The connecting disk is used to transfer the heat of the heating source, and the heat can be evenly transmitted in the connecting disk before the asphalt processing disk is heated. The heat-insulating disk itself can effectively reduce the heat of the heating source from being transmitted upward to the connected polishing device, thereby improving the heating efficiency of the heating source for the asphalt processing disk. In addition, the heat-insulating disk and the heating device are connected to the asphalt processing disk. The sources can be disassembled from each other, so it is convenient to replace heating sources with different temperature control ranges according to different types of asphalt processing disks. The asphalt processing disk can be folded from the bottom side of the connecting disk to replace different asphalt processing disks according to different types of workpieces. In this way, the asphalt processing disk is heated and softened, which can effectively reduce the phenomenon of scratches on the mirror surface caused by excessive hardness of the asphalt processing disk, improve the smoothness of the mirror polishing by the asphalt processing disk, and further reduce the intermediate frequency error generated in optical processing. Different asphalt processing disks and heating sources can be replaced according to the processing needs of different workpieces to adapt to different usage requirements. There is no need to directly replace the whole thing, and it is more versatile.

[0008] As a further improvement of the above technical solution, a heat conduction hole is provided on the outer side of the connection disk, the heat conduction hole is connected to the connection groove, and a temperature sensor is connected to the outer side of the connection disk where the heat conduction hole is provided. The heat of the asphalt processing disk at the connection protrusion position can be conducted to the temperature sensor through the heat conduction hole. In this way, the temperature sensor can more accurately measure the temperature value of the asphalt processing disk, thereby facilitating real-time temperature control of the asphalt processing disk.

[0009] As a further improvement of the above technical solution, a temperature adjustment knob is provided on the top side of the heat insulation disk, and the temperature adjustment knob, the heating source and the temperature sensor are electrically connected to each other, and the heating source is configured to heat the asphalt processing disk to the temperature setting value corresponding to the temperature adjustment knob according to the temperature value measured by the temperature sensor. According to the temperature control requirements of different asphalt processing disks, the temperature required for heating the asphalt processing disk can be adjusted by the temperature adjustment knob, and the asphalt processing disk is heated and heated by the heating source, and the real-time temperature value of the asphalt processing disk is measured by the temperature sensor, until the heating source reaches the temperature setting value required by the temperature adjustment knob, and the heating source stops working, so that the asphalt processing disk can be automatically adjusted to a suitable temperature range during the processing using the asphalt processing disk, thereby better ensuring the quality stability of mirror processing using the asphalt processing disk.

[0010] As a further improvement of the above technical solution, a digital display screen is provided on the top side of the heat insulation disk, and the digital display screen is electrically connected to the temperature sensor, and the digital display screen is used to display the temperature value measured by the temperature sensor.

[0013] As a further improvement of the above technical solution, the present invention further includes a connecting ring, which is arranged around the outside of the connecting disk and the outside of the heat insulation disk. By tightening the connecting ring around the outside of the connecting disk and the heat insulation disk, the structural connection between the connecting disk and the heat insulation disk can be further strengthened to prevent the connecting disk from being separated from the heat insulation disk during the processing of the asphalt processing disk.

[0022] Reference Figure 1 and Figure 2An asphalt grinding head comprises: a connecting plate 1, a heating groove is arranged on the top side of which; an asphalt processing plate 2, which is detachably connected to the bottom side of the connecting plate 1; a heat insulating plate 31, a heating source 32 is detachably connected to the bottom side of which, the heat insulating plate 31 is detachably connected to the top side of the connecting plate 1, the heating source 32 is located in the heating groove, and the heating source 32 is an electrical component for heating, such as a resistance wire heater, an electric heating plate, an electric heating tube, a ceramic heating element, etc.

[0023] In this asphalt grinding head, when in use, the heat insulation disk 31 is connected to the external polishing equipment, and the asphalt processing disk 2 for mirror processing is installed on the bottom side of the connecting disk 1. When the mirror processing is required, the heating source 32 works, and the heat generated by it is transmitted to the asphalt processing disk 2 through the connecting disk 1, so that the hardness of the asphalt processing disk 2 is reduced. The heat of the heating source 32 is transferred by the connecting disk 1, and the heat can be evenly transmitted in the connecting disk 1 before the asphalt processing disk 2 is heated. The heat insulation disk 31 itself can effectively reduce the heat of the heating source 32 from being transmitted upward to the connected polishing equipment, thereby improving the heating efficiency of the heating source 32 for the asphalt processing disk 2. In addition, the heat insulation disk 31 and the heating The sources 32 can be disassembled from each other, so that the heating sources 32 with different temperature control ranges can be conveniently replaced according to different types of asphalt processing disks 2. The asphalt processing disk 2 can be folded from the bottom side of the connecting disk 1 to replace different asphalt processing disks 2 according to different types of workpieces. In this way, the asphalt processing disk 2 is heated and softened, so that the phenomenon of scratches on the mirror surface caused by excessive hardness of the asphalt processing disk 2 is effectively reduced, the smoothness of the mirror polishing of the asphalt processing disk 2 is improved, and the intermediate frequency error generated in the optical processing is further reduced. In addition, different asphalt processing disks 2 and heating sources 32 can be replaced according to the processing needs of different workpieces to meet different usage requirements. There is no need to directly replace the whole, and the versatility is stronger.

[0024] In order to further improve the connection strength between the asphalt processing disc 2 and the connecting disc 1, in this embodiment, a connecting groove 11 is provided on the bottom side of the connecting disc 1, and a connecting protrusion 21 is formed on the top side of the asphalt processing disc 2, and the connecting protrusion 21 is connected in cooperation with the connecting groove 11 on the bottom side of the connecting disc 1. The asphalt processing disc 2 can quickly connect the asphalt processing disc 2 to the bottom side of the connecting disc 1 through the connecting protrusion 21 on the top side thereof, and improve the structural stability of the connection between the asphalt processing disc 2 and the connecting disc 1. In actual use, the workpiece is positioned on the processing table of the external device, and the processing table drives the workpiece to rotate. At this time, the workpiece is against the asphalt processing disc 2, providing an upward pressing pressure to the asphalt processing disc 2, and the asphalt processing disc 2 is not easy to separate from the connecting disc 1. In addition, buckles, protrusions and other structures can be added in the connecting groove 11 to cooperate with the connecting protrusion 21, thereby further improving the stability of the asphalt processing disc 2 when in use.

[0025] In order to facilitate the control of the heating temperature of the heating source 32, in this embodiment, a heat conduction hole is provided on the outside of the connection disk 1, and the heat conduction hole is connected to the connection groove 11. The outside position of the connection disk 1 provided with the heat conduction hole is connected to the temperature sensor 12. Furthermore, a groove can be provided on the outside of the connection disk 1, and the temperature sensor 12 can be embedded in the groove. The heat of the asphalt processing disk 2 at the connection protrusion 21 can be conducted to the temperature sensor 12 through the heat conduction hole. In this way, the temperature sensor 12 can more accurately measure the temperature value of the asphalt processing disk 2, thereby facilitating real-time temperature control of the asphalt processing disk 2.

[0026] Different asphalt processing discs 2 have different components and require different temperatures for heating and softening. Therefore, the heating temperature of the heating source 32 can be adjusted according to different heating temperature requirements. Specifically, a temperature adjustment knob 4 is provided on the top side of the heat-insulating disc 31. The temperature adjustment knob 4, the heating source 32 and the temperature sensor 12 are electrically connected to each other. The heating source 32 is configured to heat up to the temperature setting value corresponding to the temperature adjustment knob 4 according to the temperature measurement value of the temperature sensor 12. According to the temperature control requirements of different asphalt processing discs 2, the temperature required for heating the asphalt processing disc 2 can be adjusted by the temperature adjustment knob 4, the asphalt processing disc 2 is heated by the heating source 32, and the real-time temperature value of the asphalt processing disc 2 is measured by the temperature sensor 12. After the heating source 32 reaches the temperature setting value required by adjusting the temperature adjustment knob 4, the heating source 32 stops working. In this way, the asphalt processing disc 2 can be automatically adjusted to a suitable temperature range during the processing using the asphalt processing disc 2, thereby better ensuring the quality stability of the mirror processing using the asphalt processing disc 2.

[0027] In some embodiments, a digital display screen 5 is provided on the top side of the heat insulation disc 31, and the digital display screen 5 is electrically connected to the temperature sensor 12, and the digital display screen 5 is used to display the temperature value measured by the temperature sensor 12. The temperature value measured by the temperature sensor 12 can be intuitively obtained through the digital display screen 5, so as to facilitate the judgment of the soft and hard state of the asphalt processing disc 2 at this time, and better control the asphalt grinding head processing.

[0028] Furthermore, a mounting groove is provided on the top side of the heat-insulating plate 31, an electric control box is connected in the mounting groove, and the digital display screen 5 is connected to the top side of the electric control box. A mounting groove for mounting the electric control box is provided on the top side of the heat-insulating plate 31, and the electric control box is mainly used to place electrical components for overall control, and the digital display screen 5 is also connected to the electric control box to form a whole, making the overall structure more compact.

[0029] The electric control box can be directly installed in the heat insulation plate 31 and then locked and fixed. In this embodiment, the electric control box and the installation slot are detachably connected. The electric control box can be removed from the installation slot, so as to facilitate the replacement and maintenance of the electrical components inside the electric control box.

[0030] In the above embodiment, a connection structure can be directly provided between the connection disk 1 and the heat insulation disk 31 to fix them to each other. In order to further enhance the stability of the connection structure between the two, the present invention further comprises a connection ring 6, which is arranged around the outside of the connection disk 1 and the outside of the heat insulation disk 31. The connection ring 6 may comprise a plurality of arc-shaped connection strips, and the two connection strips are fixed to each other by fastening screws or other connecting members between two adjacent connection strips, thereby tightening the connection disk 1 and the outside of the heat insulation disk 31. By tightening the connection ring 6 to the outside of the connection disk 1 and the heat insulation disk 31, the structural connection between the connection disk 1 and the heat insulation disk 31 can be further strengthened, and the phenomenon that the connection disk 1 is separated from the heat insulation disk 31 during the processing of the asphalt processing disk 2 can be prevented.

[0031] Furthermore, a positioning protrusion 33 is provided on the bottom side of the heat insulation disc 31, and a positioning slot is provided on the top side of the connection disc 1, and the positioning protrusion 33 is connected in the positioning slot. The heat insulation disc 31 and the connection disc 1 can be quickly connected and positioned by the mutual cooperation of the positioning protrusion 33 and the positioning slot, thereby improving the convenience of the overall assembly, and effectively preventing the connection disc 1 and the heat insulation disc 31 from rotating relative to each other during the processing of the asphalt processing disc 2, thereby further improving the processing quality.
