In the embodiment, the main shaft 6 is driven by the direct drive motor, so that the volume and the weight of the polishing grinding head driving device are greatly reduced, the overall structure of the polishing grinding head driving device is simplified, the assembly is simple, the maintenance is easy, the failure rate of the device is reduced, and the production efficiency is guaranteed.
Further, as shown in fig. 1 and 3, a rotating shaft sleeve 4 is disposed between the rotor 8 and the main shaft 6, and the rotating shaft sleeve 4 is sleeved outside the main shaft 6 and is in transmission connection with the main shaft 6; the rotor 8 is in transmission connection with the rotating shaft sleeve 4; the main shaft 6 can slide relative to the rotary sleeve 4 in the axial direction of the rotary sleeve 4. Specifically, the rotor 8 is in transmission connection with the rotating shaft sleeve 4 through a flat key 9.

Because the guide block 10 and the guide groove 2301 are in sliding fit, after the guide block is used for a certain time, the guide groove 2301 is worn to cause reduction of transmission assembly precision, the problem can be avoided by replacing the lining cylinder 23 regularly, meanwhile, the lining cylinder 23 is small in size and low in machining cost, and compared with the mode of directly replacing the rotary shaft sleeve 4, the production cost can be effectively reduced.
Of course, in other embodiments, the bushing 23 may be integrally formed with the rotating sleeve 4, that is, the guide groove 2301 may be directly formed on the inner wall of the rotating sleeve 4.
In this embodiment, the guide block 10 is detachably connected to the main shaft 6 by a bolt or a screw, so that the guide block 10 can be easily replaced after being damaged. In other embodiments, the guide block 10 may also be welded to the spindle 6.
As shown in fig. 1 and 7, the polishing grinding head driving apparatus further includes a driving member 12 for driving the main shaft 6 so that the main shaft 6 can slide with respect to the rotary sleeve 4. In this embodiment, the driving member 12 is a cylinder. As shown in fig. 2, after the polishing wheel head 1 is installed and the polishing wheel head driving device is fixed on the frame of the polishing machine, the position between the driving piece 12 and the stator 7 of the direct drive motor is relatively fixed. Further, a connecting shaft sleeve 13 is sleeved outside the main shaft 6, and the connecting shaft sleeve 13 is rotatably connected with the main shaft 6 through a second bearing 22; in order to ensure the coaxiality of the connecting shaft sleeve 13 and the main shaft 6, two second bearings 22 are arranged between the connecting shaft sleeve 13 and the main shaft 6, and the two bearings are limited by a sleeve 20.
Furthermore, as shown in fig. 5 and 6, a connecting shaft sleeve 13 is sleeved outside the main shaft 6, and the connecting shaft sleeve 13 is rotatably connected with the main shaft 6; the upper end of the connecting shaft sleeve 13 is provided with a lower sealing disc 15, and an upper sealing disc 16 is sleeved outside the main shaft 6; the upper seal disc 16 can rotate along with the main shaft 6; the lower sealing disk 15 comprises a first body 1501, a first through hole 1502 is arranged on the first body 1501 in a penetrating manner, and at least two lower sliding rings 1503 are arranged on the upper surface of the first body 1501; the upper sealing disc 16 comprises a second body 1601, a second through hole 1602 penetrates through the second body 1601, and at least two upper slip rings 1603 are arranged on the lower surface of the second body 1601; the main shaft 6 penetrates through the first through hole 1502 and the second through hole 1602, and after the lower sealing disc 15 and the upper sealing disc 16 are assembled, the lower sliding ring 1503 and the upper sliding ring 1603 are distributed in a staggered mode; the driving end of the driver 12 is fixedly connected to the coupling sleeve 13 or the lower sealing disc 15.
In this embodiment, a stopper nut 21 is screwed onto the upper end of the spindle 6, the stopper nut 21 is positioned above the upper seal disk 16, and the upper seal disk 16 is stopped by screwing the stopper nut 21 to prevent the upper seal disk from falling off from the upper end of the spindle 6. Preferably, a rubber gasket is disposed between the retainer nut 21 and the upper seal disk 16 to prevent the retainer nut 21 from crushing the upper seal disk 16.
In use, the main shaft 6 passes through both the first through hole 1502 and the second through hole 1602, and the first through hole 1502 and the second through hole 1602 are coaxial. The upper sliding rings 1603 and the lower sliding rings 1503 can be two or more in one-to-one correspondence, the upper sliding rings 1603 and the lower sliding rings 1503 are nested at intervals, an upper sealing groove is formed between every two adjacent upper sliding rings 1603, a lower sealing groove is formed between every two adjacent lower sliding rings 1503, and external impurities are not prone to entering the second bearing 22 through a gap between the upper sliding rings 1603 and the lower sliding rings 1503 due to the assembling structure that the upper sliding rings 1603 and the lower sliding rings 1503 are nested at intervals.
In this embodiment, the upper slide ring 1603 abuts against the inner ring of the second bearing 22, and the lower slide ring 1503 abuts against the outer ring of the second bearing 22. The outer race of the second bearing 22 is a close fit with the inner wall of the connecting sleeve 13.
In the present embodiment, as shown in fig. 1 and fig. 2, further, a support plate 17 is fixedly mounted on the lower sealing disk 15 by bolts or screws, and a cover plate 18 is fixedly mounted on the support plate 17 by screws or bolts for close protection of the connecting structure of the upper sealing disk 16 and the lower sealing disk 15. In this embodiment, the driving end of the driver 12 is fixedly attached to the anchor plate 17 for ease of installation. In other embodiments, the drive end of the driver 12 may be fixedly connected to either of the four, as the longitudinal positions between the cover plate 18, the fulcrum plate 17, the lower sealing disk 15 and the connecting boss 13 are relatively fixed, i.e., the four are fixedly connected.
In the embodiment, when the polishing grinding head is used, the direct drive motor is electrified, the rotor 8 rotates and drives the rotating shaft sleeve 4 to synchronously rotate through the flat key 9, and the rotating shaft sleeve 4 is matched with the guide block 10 on the main shaft 6 through the guide groove 2301 on the lining cylinder 23 so as to drive the main shaft 6 to synchronously rotate, so that the polishing grinding head 1 arranged on the main shaft 6 is driven; meanwhile, when it is necessary to lift the polishing head 1 away from the ceramic to be polished or to press the polishing head 1 down close to the ceramic to be polished, the driving member 12 is actuated, the driving end thereof drives the supporting plate 17, and the driving force is transmitted to the main shaft 6 through the lower sealing disk 15, the connecting boss 13 and the second bearing 22 to achieve the longitudinal position adjustment of the polishing head 1. When the polishing grinding head 1 is lifted to be away from the polished ceramic, the driving piece 12 extends, and in the process, the guide block 10 slides upwards in the guide groove 2301, so that the polishing grinding head 1 can be lifted on the premise of not influencing the rotation of the main shaft 6, and further the polishing grinding head 1 is lifted to be away from the polished ceramic; in contrast, when the polishing grinding head 1 is pressed down to be close to the ground ceramic, the driving member 12 is shortened, the main shaft 6 and the polishing grinding head 1 are under the action of self gravity and the driving member 12, so that the main shaft 6 is subjected to downward axial acting force, and in the process, the guide block 10 slides downward in the guide groove 2301, so that the main shaft 6 can be pressed down on the premise of not influencing the rotation of the main shaft 6, and the polishing grinding head 1 is further close to the ground ceramic downward.
In this embodiment, the matching structure of the guide block 10 and the guide groove 2301 plays a role of sliding guide on one hand and a role of key transmission on the other hand.
In this embodiment, in order to supply the cooling liquid during the operation of the polishing grinding head 1, as shown in fig. 1 and 2, a cooling channel 601 is provided in the spindle 6 along the axial direction thereof. The cooling passage 601 communicates with the polishing head 1. Further, a conduit 14 is rotatably nested in the cooling channel 601, and the conduit 14 is fixedly connected to the connecting shaft sleeve 13 or the lower sealing plate 15; the conduit 14 is for external cooling equipment. The conduit 14 is inserted into the cooling channel 601 from the upper end of the main shaft 6, the upper end of the conduit passes through the cover plate 18, and the conduit 14 is sealed with the inner wall of the cooling channel 601 by a sealing ring 24. The upper end of the conduit 14 is in threaded connection with a lock cylinder 19, an inlet 1901 is formed in the side wall of the lock cylinder 19, cooling liquid is introduced into the conduit 14 from the inlet 1901 by an external cooling device, and the cooling liquid enters the cooling channel 601 through the conduit 14 and finally reaches the polishing grinding head 1. The sealing ring 24 here prevents the coolant from escaping from the upper end of the cooling channel 601. In actual use, when the seal ring 24 fails, the coolant overflows from the upper end of the cooling passage 601, and the assembled structure of the upper seal disk 16 and the lower seal disk 15 prevents the overflowing coolant from corroding the second bearing 22.
As shown in fig. 6, a drain groove 1504 is formed in the upper surface of the lower seal disk 15, and the drain groove 1504 is provided on the outer side in the circumferential direction of the lower seal disk 15 and communicates with the lower seal groove. In use, the upper seal disk 16 rotates with the main shaft 6, and when coolant overflows from the upper end of the cooling passage 601, the coolant flows into the lower seal disk 15 by the centrifugal force of the rotation of the upper seal disk 16 and overflows through the drainage groove 1504.
In this embodiment, as shown in fig. 1 and 4, the bushing 3 is disposed between the rotating sleeve 4 and the main shaft 6, the bushing 3 is slidably sleeved outside the main shaft 6, and the bushing 3 is fixedly connected to the rotating sleeve 4. The bush 3 here serves to right the spindle 6 at the lower end, prevent it from tilting in the radial direction, ensure the accuracy of the polishing head drive, and function as a sliding bearing. The bush 3 and the rotating shaft sleeve 4 are detachably connected through bolts or screws, when the bush 3 is damaged in the using process and the precision is affected, the bush can be disassembled and replaced, and compared with a mode of directly replacing the rotating shaft sleeve 4, the production cost is saved.
As shown in fig. 1 and 3, a protection sleeve 11 is disposed at an upper end of the rotation sleeve 4, the protection sleeve 11 is sleeved outside the main shaft 6, the upper end of the protection sleeve 11 extends into the connection sleeve 13 from a lower end of the connection sleeve 13, and forms a shield for the main shaft 6 together with the connection sleeve 13, thereby preventing impurities from entering a gap between the guide block 10 and the guide groove 2301.
The embodiment also provides a polishing machine, which comprises a polishing grinding head 1 and the polishing grinding head driving device, wherein the polishing grinding head driving device is used for installing and driving the polishing grinding head 1. The stator 7 of the polishing grinding head driving device and the driving piece 12 are fixedly arranged on a structural member (frame) of the polishing machine.
