[0030] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0031] The automatic leveling and compensation structure of the grinder is mainly composed of detection components, hydraulic drive components, and hydraulic transmission components; like Figure 1 , Figure 2 , Figure 3 As shown, the surface of the shaft 1 has an expanded diameter portion 12, and three connecting members 6 are distributed around the expanded diameter portion 12. The surface of the expanded diameter portion 12 has a slot portion, and the connecting members 6 are inserted into the slots one by one, and the connecting members 6 are fixed to the expanded diameter portion 12 by screws. The three connecting members 6 are in an expanded state, and three control valves 5 are fixed on the surface of the grinding disc 2. The grinding disc 2 is axially sleeved on the surface of the shaft 1, and the expanded ends of the three connecting members 6 are against the grinding disc 2, and the connecting members 6 are fixed to the grinding disc 2 by screws, and then the threaded sleeve is threadedly connected to the shaft 1 to contact the outer side of the grinding disc 2, and the threaded sleeve is fixed to the grinding disc 2 by screws, so as to achieve stable installation of the grinding disc 2; The structure of the detection component is as follows: like Figure 1 , Figure 2 As shown, a support 3 is fixed on the surface of the grinding machine body, and a vibration sensor 31 is fixed on the surface of the support 3. The vibration sensor 31 is a contact sensor, and the vibration sensor 31 contacts the surface of the shaft 1; The structure of hydraulic drive components is as follows: like Figure 3 , Figure 4 , Fig. 9As shown, three groups of hydraulic telescopic parts 8 are evenly distributed on the back of the grinding disc 2, and each group of hydraulic telescopic parts 8 is symmetrically provided with two, and a carrier 9 is arranged between each group of two hydraulic telescopic parts 8. The hydraulic telescopic parts 8 include a slide cylinder 81, and the slide cylinder 81 is fixed to the grinding disc 2. A slide plug 82 is adapted to slide inside the slide cylinder 81, and a chamber for accommodating hydraulic oil is formed between one side of the slide plug 82 and the slide cylinder 81. A telescopic handle 83 is fixed to the other side of the slide plug 82, and the telescopic handle 83 passes through the slide cylinder 81 and is connected to the carrier 9. A slide cavity 21 is provided on the back of the grinding disc 2, and the carrier 9 is placed in the slide cavity 21. The three counterweights 7 are fixedly connected to the carrier 9 by screws respectively. Each control valve 5 has two control paths for connecting two hydraulic telescopic members 8. Each hydraulic telescopic member 8 is connected to an independent hydraulic channel through the control valve 5. The hydraulic channel is connected to an external hydraulic device. The hydraulic device refers to an existing hydraulic drive and control device. The hydraulic device is used to control the transmission of hydraulic oil to each hydraulic channel. The vibration sensor 31 is connected to the hydraulic device through the controller. The vibration sensor 31 is used to monitor the rotation vibration state of the shaft 1 in real time. When the vibration value of the shaft 1 exceeds the set value, the equipment needs to enter the dynamic leveling mode. This mode is performed in a non-processing state. The shaft 1 and the grinding disc 2 rotate, and the vibration sensor 31 feeds back information to the controller. The controller controls the hydraulic equipment to work. The leveling logic adopts a test adjustment mode to adjust the positions of the three counterweights 7 one by one, and the adjustment information is fed back through the vibration sensor 31 until the vibration value of the shaft 1 monitored by the vibration sensor 31 reaches the set value. The dynamic leveling modes are as follows: The controller controls the hydraulic equipment to conduct hydraulic oil to one of the hydraulic telescopic parts 8 corresponding to the first counterweight 7. The hydraulic oil enters the slide 81 through the hydraulic channel and the control valve 5, so that the hydraulic telescopic part 8 is extended, and the hydraulic channel of another hydraulic telescopic part 8 in the same group is opened to discharge the hydraulic oil to shorten the hydraulic telescopic part 8, so that the first counterweight 7 is gradually deflected in one direction. The vibration sensor 31 feedbacks the vibration information. If the vibration information increases, the controller controls the two hydraulic telescopic parts 8 in the group to push the first counterweight 7 to move in the opposite direction, so that the feedback vibration value of the vibration sensor 31 gradually decreases until the vibration value increases again, and the position adjustment of the first counterweight 7 is stopped. At this time, if the vibration value monitored by the vibration sensor 31 meets the set value, the dynamic leveling is completed. If the value is still unqualified, the position of the second counterweight 7 is adjusted by the controller. The adjustment method is the same as the adjustment method of the first counterweight 7. The vibration sensor 31 monitors the vibration change of the second counterweight 7 during the position adjustment process. If the value is qualified, the adjustment is completed. If it is unqualified, the position adjustment of the third counterweight 7 is started until the vibration value reaches the set value.

[0032] The structure of hydraulic transmission components is as follows: like Figure 5 , Figure 6 , Figure 7 , Figure 8 As shown, the hydraulic passage includes an oil passage 14 extending and distributed along the inside of the shaft 1, a through cavity 61 penetrating both ends of the connecting member 6 is provided inside the connecting member 6, the oil passage 14 penetrates the through cavity 61 through the first oil hole 13, and the first oil hole 13 is evenly distributed around the shaft 1, the other end of the through cavity 61 is connected to the control valve 5, a sleeve 4 is provided outside the shaft 1, a plurality of annular cavities 41 are provided on the inner wall of the sleeve 4, sealed bearings are provided at both ends of the sleeve 4 and between adjacent annular cavities 41, the oil passage 14 penetrates the annular cavities 41 one by one through the second oil hole 15, and the second oil hole 15 is evenly distributed around the shaft 1, a multi-channel solenoid valve of the hydraulic equipment is provided on the surface of the support 3, each annular cavity 41 is connected to the multi-channel solenoid valve of the hydraulic equipment through a pipeline, and a hard pipeline is used for connection so that the sleeve 4 is kept fixed relative to the support 3; The annular cavity 41, the second oil hole 15, the oil channel 14, the first oil hole 13, and the through cavity 61 constitute a complete channel. The hydraulic equipment guides the hydraulic oil into the annular cavity 41. When the shaft 1 and the sleeve 4 rotate relative to each other, the hydraulic oil passes through the second oil hole 15, the oil channel 14, the first oil hole 13, the through cavity 61, and the control valve 5 and enters the hydraulic telescopic part 8, so that the hydraulic telescopic part 8 extends. Similarly, when the hydraulic telescopic part 8 contracts, the hydraulic oil is guided back to the hydraulic equipment.

[0033] like Fig.10 As shown, the control valve 5 includes a valve body 51, the valve body 51 is fixed to the grinding disc 2, an external oil port 52 is arranged on the surface of the valve body 51, the external oil port 52 is connected with the through cavity 61, the external oil port 52 extends inwardly to be connected with a telescopic cavity 54, the diameter of the telescopic cavity 54 is larger than the diameter of the external oil port 52, an oil inlet valve column 55 is connected in the telescopic cavity 54 through a spring, the external oil port 52 at the end of the oil inlet valve column 55 is adapted and plugged, the side of the telescopic cavity 54 is connected with the internal oil port 53, the internal oil port 53 is connected with the slide cylinder 81, the one-way valve assembly includes an oil return cavity 57 that is connected with the side of the internal oil port 53, the side of the oil return cavity 57 has a guide cavity 58 that is connected with the external oil port 52, and the oil discharge valve column 56 is elastically slidable in the oil return cavity 57 through a spring; Under normal conditions, the oil inlet valve column 55 is elastically inserted to block the outer oil port 52, and the oil discharge valve column 56 is elastically close to the inner oil port 53 to block the guide cavity 58, so that the amount of hydraulic oil in the hydraulic telescopic component 8 is sealed. The length of the hydraulic telescopic component 8 is fixed, and the position of the counterweight block 7 is kept fixed. When the hydraulic oil is transmitted to the hydraulic telescopic component 8, the oil enters the outer oil port 52, and the oil inlet valve column 55 is contracted toward the telescopic cavity 54 by the oil pressure to open the outer oil port 52. The oil automatically enters the hydraulic telescopic component 8 through the telescopic cavity 54 and the inner oil port 53. In this state, even if the oil discharge valve column 56 is opened by the pressure to open the guide cavity 58, the guide cavity 58 and the outer oil port 52 are connected to the hydraulic telescopic component 8. The extension of one hydraulic telescopic component 8 in the same group will compress the other hydraulic telescopic component 8 to automatically shrink. When the pressurized hydraulic telescopic component 8 shrinks, the oil inlet valve column 55 is inserted into the external oil port 52 to block the passage of the telescopic chamber 54, and the oil in the hydraulic telescopic component 8 enters the oil return chamber 57 from the internal oil port 53. The oil discharge valve column 56 slides across the guide chamber 58 under the action of oil pressure, so that the oil return chamber 57 and the guide chamber 58 are connected. The oil is discharged through the oil return chamber 57, the guide chamber 58 and the external oil port 52 in turn, so that the hydraulic telescopic component 8 can automatically release the oil and shrink.

[0034] like Figure 5 , Figure 6 As shown, both ends of the connector 6 have protruding nozzles 62 aligned with the through cavity 61. When the connector 6 is fixedly connected to the shaft 1 and the control valve 5, the protruding nozzles 62 are automatically inserted into the first oil hole 13 and the external oil port 52 to complete the oil circuit sealing connection.

[0035] like Fig.10 As shown, micro switches 59 are provided at one end of the telescopic chamber 54 away from the external oil port 52 and at one end of the oil return chamber 57 away from the internal oil port 53. When the oil inlet valve column 55 moves to open the external oil port 52 or the oil discharge valve column 56 moves to open the guide chamber 58, the oil inlet valve column 55 and the oil discharge valve column 56 can touch the corresponding micro switches 59. The micro switch 59 is connected to the main machine of the grinder through a controller. When dynamic leveling is performed, information is fed back to the controller through the micro switch 59 to determine whether the control valve 5 and the oil circuit are faulty. If the oil inlet valve column 55 fails to touch the micro switch 59 when oil is being fed to the hydraulic telescopic part 8, it indicates that the oil circuit or the oil inlet valve column 55 is faulty. If the oil discharge valve column 56 fails to touch the micro switch 59 when the hydraulic telescopic part 8 is in a contracted state, it indicates that the oil circuit or the oil discharge valve column 56 is faulty, which is convenient for maintenance personnel to repair the equipment in time.

[0036] like Fig.11 As shown, since the interior and surface of the shaft member 1 need to be processed into the first oil hole 13, the oil passage 14, and the second oil hole 15, the longer size is not convenient for processing, and the shaft member 1 is set as an independent component. The driving component of the grinder is connected to the driving shaft 11, and the shaft member 1 is connected to the driving shaft 11 through a flange, and the oil passage 14 is directly axially processed from the flange end face of the shaft member 1, and the flange end face of the shaft member 1 has a groove 16, and the flange end face of the driving shaft 11 has a cam 17 that fits the groove 16, and the surface of the cam 17 has a plurality of insert handles 18. When the shaft member 1 is connected to the driving shaft 11, the insert handles 18 are fitted into the oil passage 14 one by one, and at the same time, the cam 17 and the groove 16 are fitted and snap-fitted to achieve high-precision sealing of the oil passage 14.

[0037] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
