The invention relates to the technical field of automatic material carrying and provides a light-load material carrying robot. The carrying robot comprises a bottom slewing mechanism, a Z-axis linearmoving mechanism, a horizontal linear moving mechanism, a hand slewing mechanism, a mechanical claw and a balance weight system. The Z-axis linear moving mechanism is fixed to the bottom slewing mechanism. The Z-axis linear moving mechanism and the horizontal linear moving mechanism are connected. The horizontal linear moving mechanism is connected with the mechanical claw through the hand slewingmechanism. The hand slewing mechanism moves on the horizontal linear moving mechanism in the horizontal direction. The hand slewing mechanism controls the connected mechanical claw to rotate. The mechanical claw achieves grabbing and releasing of materials. The balance weight system is connected with a cantilever of the horizontal linear moving mechanism through a steel wire rope. The robot effectively overcomes the defects that an existing four-freedom-degree connecting rod type joint carrying robot is insufficient in work space reaching, high in manufacturing cost and high in self-weight.

The invention discloses a casting grinding device with high stability. The casting grinding device comprises a rack, an electromotor and a cutting blade. The electromotor is arranged on the rack and connected with a rotary shaft of the cutting blade through a chain. A silencer is arranged at the position, close to the cutting blade, of the middle of the rack. Anti-vibration mechanisms are arranged at the bottom of the rack. Each anti-vibration mechanism comprises side plates and a base, wherein a fixing shaft is arranged between the side plates and sleeved with a sliding connecting block, and the top end of the sliding connecting block is connected with the bottom of the rack. Bearings and bearing seats are arranged between the end faces of the fixing shafts and the side plates, the fixing shafts are sleeved with elastic parts, and the elastic parts are arranged between the bearings and the sliding connecting blocks. The situation that a casting is manually ground and is damaged is avoided, the speed is high, production efficiency is improved, and production cost is reduced; and the noise generated in the re-operating process is lowered, and the stability in the working process is improved.
