Description

Technical Field

[0001] This utility model relates to the field of grinding equipment technology, specifically to a hole grinding device for stator flange processing. Background Technology

[0002] Utility model patent CN215239862U discloses a grinding device for flange holes, including a worktable, a mounting plate, a rotating shaft, a grinding device, and a transmission device. The mounting plate is fixed on the worktable, and the rotating shaft is rotatably connected to the worktable. A main gear is fixed on the rotating shaft, and multiple support columns are arrayed on the main gear. Each support column is fixedly connected to the main gear. The grinding device includes a drive motor, and a grinding disc is fixed to the output end of the drive motor. This utility model grinds the holes on the flange by lowering the grinding device. After grinding, the grinding device moves upward, driving the transmission device to rotate the flange and rotate the un-grinded holes to directly below the drive motor for subsequent grinding. The grinding efficiency is high, eliminating the need for grinding personnel to grind the holes around the flange, and also saving time and effort by eliminating the need for manual flange rotation.

[0003] However, when using this device, it is not convenient to adjust its position to grind holes in different locations, and it is also not convenient to grind holes of different sizes. Utility Model Content

A hydraulic cylinder 35 is fixedly mounted on the upper end of the bracket 2, located to the right of the motor 31. The hydraulic rod of the hydraulic cylinder 35 passes through the bracket 2 and is slidably connected to it. A sliding pin 36 is fixedly connected to the surface of the hydraulic rod of the hydraulic cylinder 35. The sliding pin 36 is slidably connected to the turntable 34. By setting the sliding pin 36, the turntable 34 and... The hydraulic rod is connected, and the lower end of the slide cylinder 33 is fixedly connected to the guide rail 37.

The screw 39 and the slider 38 are connected by a thread. By setting the screw 39, the slider 38 is controlled to move. The square rod 32 is driven to rotate by the motor 31, which in turn causes the slide cylinder 33 to drive the guide rail 37 to rotate, thereby changing the orientation of the guide rail 37. At the same time, by rotating the screw 39 and the slider 38 to make threaded movements, the position of the frame 4 changes, thereby allowing the device to grind and process any hole on the flange.

[0022] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 The angle changing mechanism 5 includes a motor 51. The motor 51 is fixedly installed inside the frame 4.

[0023] The specific implementation process of this utility model is as follows: In use, the stator flange is placed on the base plate 1, and the cylinder 7 is started to drive the clamping plate 8 to move, so that the clamping plate 8 contacts the stator flange and clamps the stator flange. The motor 31 is started, and the motor 31 drives the square rod 32 to rotate. The square rod 32 drives the slide cylinder 33 to rotate, which in turn drives the guide rail 37 to rotate, thereby changing the orientation of the guide rail 37. At the same time, the screw 39 and the slider 38 are rotated to make threaded movements, thereby causing the slider 38 to move within the guide rail 37. The slider 38 drives the frame 4 to move, thereby changing the position of the frame 4, so that the device can handle any hole on the flange. The grinding process is performed, and then the device is adjusted according to the size of the hole to be processed. The adjusting rod 55 and the support shaft 52 are manually rotated to make a threaded movement, which causes the sliding ball 56 to slide in the support bar 54, thereby changing the angle of the grinding strip 53. Then, the hydraulic cylinder 35 is activated, which drives the hydraulic rod to extend. The hydraulic rod drives the sliding pin 36 to move, and the sliding pin 36 drives the turntable 34 to move, which causes the turntable 34 to drive the sliding cylinder 33 to move, so that the grinding strip 53 contacts the hole to be processed. The motor 51 is activated, which drives the support shaft 52 to rotate, which in turn causes the grinding strip 53 to rotate. This allows grinding of holes of any size.
