Description

Technical Field

[0001] This utility model relates to the technical field of mirror plate grinding equipment for hydro-generator sets, and in particular to a mirror plate grinding device. Background Technology

[0002] During the power generation and operation of the hydro-generator unit, the induced current generated on the surface of the mirror plate and the tiny impurities in the lubricating oil will cause certain damage to the surface of the mirror plate, reducing its surface roughness. In order not to affect the normal operation of the generator unit, the surface of the mirror plate needs to be treated in time. The common method is to remove the mirror plate and then polish the worn surface of the mirror plate.

[0003] Currently, when polishing mirror plates, it is inconvenient to fix the mirror plates in place. Usually, the worker holds the mirror plate and places it close to the polishing disc, which is then driven by a motor to polish the mirror plate. However, due to the high-speed rotation of the polishing disc, there are significant safety hazards during the polishing process. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a mirror plate grinding device, which solves the problem that existing grinding devices are not convenient for fixing the mirror plate during the grinding process.

[0005] According to an embodiment of the present invention, a mirror plate grinding device includes: a base, a top plate, and a support base. A hydraulic cylinder is vertically mounted on the base, and the top plate is horizontally fixed to the output end of the hydraulic cylinder. There are two support bases, which are symmetrically arranged on the top of the base. The top of the support base is used to place the mirror plate. Each support base is provided with a fixed seat and a sliding seat on its top. A driving component is provided on the top of the base on one side of each sliding seat. The driving component is used to drive the sliding seat and the fixed seat to cooperate and clamp the mirror plate. A grinding disc is rotatably mounted on the bottom of the top plate directly above the two support bases via a rotating shaft. A driving mechanism for driving the two rotating shafts to rotate is provided on the top of the top plate.

[0006] Compared with the prior art, this utility model has the following advantages: A fixed seat and a sliding seat are set on the top of the support base. A driving component drives the sliding seat to slide, so that the sliding seat moves towards or away from the fixed seat, thereby clamping or releasing the mirror plate on the top of the support base. After the fixed seat and the sliding seat clamp the mirror plate, the driving mechanism located on the top of the top plate drives two rotating shafts to rotate. The two rotating shafts drive the grinding disc to rotate, and then the hydraulic cylinder drives the top plate to move vertically downward, so that the grinding disc grinds the mirror plate on the top of the support base. The grinding of the mirror plate is achieved in the above way, which can quickly and effectively grind the mirror plate and improve the convenience of mirror plate grinding.

[0007] Furthermore, each of the drive components includes: a lead screw, a fixed plate, and a sliding plate. The sliding plate is slidably disposed on the top of the base, the fixed plate is fixed on the top of the base, the lead screw is rotatably disposed between the support and the fixed plate, and the lead screw passes horizontally through the sliding plate. The lead screw is threadedly connected to the sliding plate, and a mounting rod is provided on the top of the sliding plate. One end of the mounting rod is fixed to the side wall of the sliding seat.

[0008] Furthermore, each of the aforementioned lead screws passes horizontally through a fixed plate, and a handle is fixedly provided at one end of the lead screw passing through the fixed plate.

[0009] Furthermore, the drive mechanism includes: a motor, drive teeth, transmission teeth, and a transmission belt. The motor is fixed to the top of the top plate by a mounting bracket. A drive shaft is fixedly installed at the output end of the motor. One end of the drive shaft is rotatably connected to the top of the top plate. The drive teeth are fixed on the drive shaft. There are two transmission teeth, both of which are fixed on the rotating shafts of the two grinding discs. The transmission belt is sleeved on the drive teeth and the two transmission teeth.

[0010] Furthermore, each of the aforementioned fixed seats and the corresponding sliding plates is fixedly provided with clamping pads on their opposite sides.

[0011] Furthermore, a support is provided at the bottom of the base, and a crossbar is provided on the side wall of the support. The hydraulic cylinder is fixed to the top of the crossbar and passes vertically through the base. Attached Figure Description

[0014] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0015] like Figure 1As shown in the figure, this utility model embodiment proposes a mirror plate grinding device, including: a base, a top plate 3 and a support base 4. A hydraulic cylinder 2 is vertically mounted on the base, and the top plate 3 is horizontally fixed to the output end of the hydraulic cylinder 2. There are two support bases 4, which are symmetrically arranged on the top of the base. The top of the support base 4 is used to place the mirror plate 9. Each support base 4 is provided with a fixed seat 5 and a sliding seat 6 on its top. A driving component is provided on the top of the base on one side of each sliding seat 6. The driving component is used to drive the sliding seat 6 to cooperate with the fixed seat 5 to clamp the mirror plate 9. The bottom of the top plate 3 directly above the two support bases 4 is provided with a grinding disc 7 rotatably mounted on the bottom through a rotating shaft 8. A driving mechanism for driving the two rotating shafts 8 to rotate is provided on the top of the top plate 3.

[0016] A fixed seat 5 and a sliding seat 6 are provided on the top of the support base 4. A drive assembly is provided to drive the sliding seat 6 to slide, so that the sliding seat 6 moves towards or away from the fixed seat 5, thereby clamping or releasing the mirror plate 9 on the top of the support base 4. After the fixed seat 5 and the sliding seat 6 clamp the mirror plate 9, the drive mechanism located on the top of the top plate 3 drives the two rotating shafts 8 to rotate. The two rotating shafts 8 drive the grinding disc 7 to rotate, and then the hydraulic cylinder 2 drives the top plate 3 to move vertically downward, so that the grinding disc 7 grinds the mirror plate 9 on the top of the support base 4. The grinding of the mirror plate 9 is achieved in the above way, which can quickly and effectively grind the mirror plate 9 and improve the convenience of grinding the mirror plate 9.

[0017] Furthermore, each of the aforementioned drive components includes: a lead screw 12, a fixed plate 10, and a sliding plate 11. The sliding plate 11 is slidably disposed on the top of the base, the fixed plate 10 is fixed on the top of the base, the lead screw 12 is rotatably disposed between the support base 4 and the fixed plate 10, and the lead screw 12 passes horizontally through the sliding plate 11. The lead screw 12 is threadedly connected to the sliding plate 11, and a mounting rod 13 is provided on the top of the sliding plate 11. One end of the mounting rod 13 is fixed to the side wall of the sliding base 6.

[0018] Specifically, when the position of the sliding seat 6 needs to be adjusted, simply rotate the lead screw 12 to drive the sliding plate 11 towards the support seat 4. The sliding plate 11 pushes the mounting rod 13 and the sliding seat 6 towards the fixed seat 5, thereby clamping the mirror plate 9 between the fixed seat 5 and the sliding seat 6. Conversely, when the mirror plate 9 needs to be released, simply rotate the lead screw 12 to move the sliding plate 11 away from the support seat 4. Furthermore, each lead screw 12 passes horizontally through the fixed plate 10, and a handle 14 is fixedly provided at one end of the lead screw 12 passing through the fixed plate 10 to facilitate rotation of the lead screw 12. At the same time, clamping pads 20 are fixedly provided on the opposite sides of the fixed seat 5 and the corresponding sliding plate 11 to prevent excessive squeezing force between the sliding seat 6 and the fixed seat 5, which could damage the mirror plate 9.

[0019] The drive mechanism includes a motor 15, drive gears 17, transmission gears 18, and a transmission belt 19. The motor 15 is fixed to the top of the top plate 3 via a mounting bracket 16. A drive shaft is fixedly mounted on the output end of the motor 15, and one end of the drive shaft is rotatably connected to the top of the top plate 3. The drive gears 17 are fixed on the drive shaft. There are two transmission gears 18, both of which are fixed on the rotating shafts 8 of the two grinding discs 7. The transmission belt 19 is sleeved on the drive gears 17 and the two transmission gears 18. Specifically, the motor 15 drives the drive shaft to rotate, which in turn drives the drive gears 17 to rotate. The drive gears 17, through the transmission belt 19, drive the two transmission gears 18 to rotate, ultimately causing the two rotating shafts 8 and the grinding discs 7 at the ends of the rotating shafts 8 to rotate together.

[0020] like Figure 1 As shown, a bracket 21 is provided at the bottom of the base, and a crossbeam 22 is provided on the side wall of the bracket 21. The hydraulic cylinder 2 is fixed to the top of the crossbeam 22 and passes vertically through the base.
