Command switch operation. It simplifies the operation of switching between multiple individual commands of the software, reduces the command switching time, realizes fast and effective command switching, improves the design efficiency, and is not prone to errors.

The invention provides a positioning device for assembling and welding of upper beams of a pallet fork frame of a forklift. The positioning device comprises a positioning platform. An adjustment mechanism and two positioning mechanisms are fixedly arranged on the upper end face of the positioning platform, wherein the adjustment mechanism is used for slightly adjusting the height of the T-shaped upper beam, and the positioning mechanisms are used for positioning the T-shaped beam and the L-shaped beam and slightly adjusting the height of the L-shaped upper beam. The two positioning mechanisms are symmetrically arranged at the two sides of the adjustment mechanism. According to the positioning device, mold positioning of the L-shaped and the T-shaped upper beams of the pallet fork frame is achieved, mutual switching is convenient and rapid, and the positioning requirement of upper beams with various lengths can be met. In addition, the inclination angle of the working surfaces of the upper beams can be rapidly and slightly adjusted according to the actual blank condition of a fed workpiece, the surface of the workpiece is prevented from being damaged during fine adjustment, and the surface quality of pallet fork frame products is better guaranteed.

The invention provides a combined execution mechanism for numerical control and intelligent polishing and belongs to the technical field of optical and mechanical precision machining. The combined execution mechanism for numerical control and intelligent polishing is provided for solving the technical problems that complex and troublesome dismounting and mounting occur to a polishing disk and a polishing wheel which are iteratively used during high-precision plane grinding and polishing and optical grinding and polishing of elements and components in the machining process. A one-to-two speed changer of the execution mechanism is fixed to an execution mechanism base plate. A polishing wheel is fixed to the one-to-two speed changer. One end of a rigid coupling is connected with a shaft of the one-to-two speed changer. The other end of the rigid coupling is connected with an eccentric disk. The eccentric disk is fixedly connected with a polishing disk through a polishing rod. A cylinder block of a two-way precision adjustment cylinder is fixed to the center position of an execution mechanism bottom plate. Sliding blocks are connected with guide rails through clamping grooves. The sliding blocks can slide on the slide rails. Through the combined execution mechanism, the complex and troublesome dismounting and mounting process when the polishing disk or the polishing wheel are iteratively used in the machining process is effectively avoided, and the purposes of conducting fast production, improving the efficiency, lowering the cost and reducing the risk are achieved.

The invention provides a front-end manipulator for car assembly. The front-end manipulator comprises a base, two car body pre-positioning components, an X-Y adjusting disc, a horizontal adjusting joint, a first workpiece positioning mechanism, a second workpiece positioning mechanism, two car body auxiliary positioning mechanisms, a centering device, two fender positioning components and a car running-in servo electric cylinder, wherein the centering device is arranged at the lower front part of a frame of the base; and the car running-in servo electric cylinder is arranged at the center of the lower front part of the first workpiece positioning mechanism. By adoption of the front-end manipulator provided by the invention, the car front-end assembly precision can be guaranteed; meanwhile, the automated assembly operation can be achieved and the problem about the instability of manual assembly can be solved; and in the mode of production, the front-end manipulator serves as automated equipment, thereby reducing the labor intensity of an operator and the cost of human resources.

The invention discloses a flexible cabinet entry system and a cabinet entry method for an expanded shredded tobacco cooked silk cabinet. On the basis of the existing cooked silk cabinet, a feeder connected to an airflow module shredded tobacco and a limit positioning mechanism are added. The feeder is arranged on the material laying Above the carriage and between No. 2 and No. 3 cabinets, the limit positioning mechanism is set at the left end of the travel rail.

The invention discloses a process for treating oily wastewater by using a fluidized bed and a device thereof, which comprises the steps: the oily wastewater enters from a lower end of the fluidized bed to pass through the fluidized bed which carries a high oil-absorption resin bed layer from downward to upward and the high oil-absorption resin absorbs oily constituent; in the post-treatment process of the oil-absorption resin, extractants enter from an upper end of the fluidized bed to pass through the oil-absorption material bed layer from upward to downward; the oily pollutant absorbed by the oil-absorption material is extracted to be discharged from an outlet of the lower end of the fluidized bed; the fluidized bed device is a conical structure which is big at the upper part and small at the lower part and is provided with a stirring device; an inlet of the oily wastewater is arranged on the lower head of the fluidized bed. The invention prevents from occurrence that resistance of the bed layer is increased which is caused by expansion of the resin after oil absorption and pressure drop is increased when the oily wastewater flows through the bed layer. The invention has high oil-absorption efficiency and the oil-absorption resin can be repeatedly used.
