A laser heat-assisted high-efficiency grinding test bench for hard and brittle materials

Abstract

The invention discloses a laser-heating-assisted efficient grinding experiment table for a hard and brittle material. The laser-heating-assisted efficient grinding experiment table comprises a base body, a grinding wheel support device, a clamping tool support device and a laser heating device. The grinding wheel support device comprises a motor and a vertical feeding device. The output end of the motor is connected with a horizontal shaft through a coupling I. The horizontal shaft is sleeved with a grinding wheel. The other end of the horizontal shaft is connected with a vertical rod fixed to the base body through a shaft seat. The shaft seat can slide in the axial direction of the vertical rod. The vertical feeding device is fixedly connected with the base body. According to the laser-heating-assisted efficient grinding experiment table, laser heating assistance is applied to grinding, and grinding efficiency and grinding quality are improved; the motor coupling is adopted for directly driving the grinding wheel, the grinding wheel is driven to grind a workpiece, transmission errors and accumulative transmission errors generated in the transmission link are reduced, the utilization rate of motor power is increased, and the rotating speed of the grinding wheel is guaranteed; and a gantry type mechanism is adopted for supporting the horizontal shaft, namely a grinding wheel shaft, rigidity of the horizontal shaft can be guaranteed, vibration of the shaft ends is effectively reduced, and furthermore, grinding precision can be correspondingly improved.

Description

technical field [0001] The invention relates to the field of grinding, in particular to a laser heat-assisted high-efficiency grinding experimental platform for hard and brittle materials. Background technique [0002] Hard and brittle materials such as engineering ceramics and optical glass have good mechanical properties and physical properties such as high hardness and high strength, and are widely used in national defense, machinery, electronics and other fields. However, due to its high hardness and brittleness, defects such as cracks are prone to occur on the processed surface. Traditional processing methods, such as polishing, have low production efficiency, large human influence factors, difficult to accurately control, and difficult to realize the automation of the production process, and the polishing liquid will cause damage to the surface. Pollution affects the physical properties of its surface layer, and the current parts tend to be miniaturized, and the diffic...

Problems solved by technology

Traditional processing methods are prone to produce microcracks and subsurface damage layers. However, plastic domain processing is different from brittle material removal processing. Plastic domain processing is the removal of chips from the material surface by plastic deformation, and no cracks are generated on the processed surface.
