Description

Technical Field

[0001] The utility model relates to the technical field of grinding gas turbine bolts, in particular to a grinding device for gas turbine bolts. Background Art

[0002] Gas turbine bolts are bolts used to fix gas turbine components. They are usually made of high-strength metal materials and can withstand high temperature and high pressure working environments. Gas turbine bolts usually adopt special design and processing technology to ensure that they have good tensile, creep and fatigue resistance, thereby ensuring the safe and reliable operation of gas turbines.

[0003] A grinding and polishing device for high-strength bolt production disclosed in announcement number CN216327518U has a good polishing effect because the bolts are ground by rotating a grinding roller in cooperation with a baffle. While the grinding roller rotates, the screen plate can be driven to move up and down through a screening assembly, so that the screen plate can screen the ground bolts and abrasives, making it convenient for staff to separately recover the ground bolts and abrasives. The operation is relatively convenient and the processing efficiency is improved.

[0004] However, this high-strength bolt production grinding and polishing device has the following disadvantages:

[0005] When grinding bolts, there is a lack of positioning of the bolts, and the bolts cannot be ground at fixed points according to the grinding requirements of the bolts;

[0006] When grinding bolts, the temperature of the bolts will rise, and grinding debris will remain in the thread gaps on the surface. The high temperature and the influence of the debris will cause the thread texture and shape of the bolts to deform.

[0007] In view of this, the present utility model is proposed. Utility Model Content

[0013] Optionally, a telescopic plate is fixedly connected to the side surface of the L-plate, and an L-shaped plate is provided at one end of the telescopic plate.

[0014] Optionally, a grinder for grinding bolts is provided at the top of the L-shaped plate, one end of the grinder is at the same horizontal line with the surface of the U-shaped frame, and the grinder and the U-shaped frame are at the same horizontal line. When the bolt is fixed inside the U-shaped frame, the grinding part can be directly moved to the surface of the bolt for grinding by moving the grinder.

[0015] Optionally, a handle for adjusting the telescopic length of the telescopic plate is provided on the surface of the L-shaped plate, and a non-slip sleeve is sleeved on the surface of the handle.

[0018] 2. The grinding device for gas turbine bolts can connect the driving motor to an external power source during grinding by setting up the blowing assembly, so that it drives the impeller blades to rotate inside the wind tube, and no wind force is generated inside the wind tube. The air is blown to the surface of the bolt through the conical tube, and the debris in the thread pattern on the surface of the bolt can be blown away and removed.
