Examples effects and effects

According to the work piece delivery device of this embodiment, owing to have moving mechanism and bearing arm for the bearing work piece and remove the work piece to the target location, consequently the operation personnel is convenient laborsaving more to the removal of work piece when carrying out the operation, can reduce operation intensity effectively, only need alone alright accomplish the operation, and the work piece can not produce and rock in the operation process simultaneously, also is difficult for causing accidents such as dropping, has improved the security of operation. Owing to have adjustment mechanism, consequently the operation personnel need not through the manpower alright in order to adjust the position of work piece when the operation for location to the work piece is more accurate, and the efficiency of operation is higher, also lighter during the operation.

Because have telescopic bearing arm and connect member, horizontal adjusting part and vertical adjusting part, be used for adjusting the interval between two bearing arms, the bearing arm along the ascending position of the length direction of bearing arm mounting panel and the subassembly that floats along the ascending position of bearing arm length direction respectively, consequently adjustment mechanism in this embodiment has the ascending regulatory function in three side, has further improved precision and the operating efficiency to the work piece position location.

Because the bearing arm is also provided with the floating assembly, when the floating assembly is in a floating state, the position of the positioning pin can be further finely adjusted, so that an operator can more accurately insert the positioning pin into the positioning pin hole during operation, and the operation precision is further improved. In addition, when the floating assembly is in a locking state, the displacement of the workpiece in the horizontal direction can be limited, so that the workpiece is not shaken, and the safety in the operation process is improved.

Because be equipped with the scale respectively on bearing arm mounting panel and the bearing arm, consequently at operation in-process operation personnel can reduce the regulation time of bearing arm according to the more accurate location of the instruction of scale.

Because the bearing arm is connected the member, transversely adjusts the subassembly and vertically all is equipped with adjustment handle on the subassembly, consequently the operation in-process is more convenient to the position adjustment of bearing arm and subassembly that floats, and the operation is simpler.

Because the bearing arm passes the bearing arm mounting panel through the slotted hole, the mounting height of bearing arm has been reduced by a wide margin, make the upper surface of the subassembly that floats on the bearing arm be a little higher than the upper surface of bearing arm mounting panel, consequently make the operation in-process work piece can backward move fully, until leaning on the lift limiting plate who lives the bearing arm mounting panel, thereby make the focus of work piece consignment device in this embodiment move backward, the effective safe load of the work piece consignment device in this embodiment has been increased, can be applicable to the heavy work piece of large size, the security performance is stronger.

Because the workpiece consignment device in the embodiment adopts the frame structure, the bearing capacity is effectively improved while the self weight and the overall dimension are reduced, and therefore, the workpiece consignment device can meet various complex space requirements.

The foregoing has described in detail preferred embodiments of the present invention. It should be understood that numerous modifications and variations could be devised by those skilled in the art in light of the teachings of this invention without undue experimentation. Therefore, the technical solutions that can be obtained by a person skilled in the art through logic analysis, reasoning or limited experiments based on the prior art according to the concepts of the present invention should be within the scope of protection defined by the claims.
