The invention relates to a ceramic hole processing device, in particular to an engineering-ceramic complex-frequency ultrasonic processing device and solves problems that an existing processing device is poor in processing quality and efficiency, high in cost and limited in processing shape. The engineering-ceramic complex-frequency ultrasonic processing device comprises a frame, an amplitude-change pole is arranged on the frame, a transducer connected with the amplitude-change pole is arranged at the lower end of the same, a stepped connecting block with the upper diameter larger than the lower diameter and connected with the amplitude-change pole is arranged at the upper end of the same, the stepped connecting block is sleeved with a free-quality casing located between the stepped surface of the stepped connecting block and the upper end face of the amplitude-change pole, a drill is connected to the upper end of the stepped connecting block, a workpiece worktable is arranged above the drill, and a guide rail sliding vertically is arranged on one side of the workpiece worktable. The engineering-ceramic complex-frequency ultrasonic processing device is reasonable and reliable in structural design, low in energy consumption, simple in structure and light in weight, processing precision and processing efficiency are greatly improved, few movement parts are involved, rotational motion is omitted, keeping of rotation torque is not needed, and the device can be used for environments under high temperature, low temperature or vacuum and the like.

The invention relates to a horizontal reference device for the guidance system. It includes the measuring table, the adjusting bolt and the basement. The top of the measuring table is the base table and the lower is the soleplate which is parallel with the base table. The cross rib plate is between the base table and the soleplate which is set with four bolt holes in which is the adjusting bolt. The bottom of the adjusting bolt is welded on the basement. The upper nut is spinning on the screw thread of the lug bolt hole and the down nut is spinning on the screw thread of the down surface adjusting bolt. The measuring table is fixed with the adjusting bolt by the four upper and down nuts. The top of the basement is the table which is welded with the four adjusting nuts and the reinforced rib plate is welded on the shipping board. The device can be fixed in the defined position of the ship to get the high precision of the horizontal and install easily.

The invention discloses a ship deck block building method. A cargo hold block and deck panels are supplied, a plurality of supporting columns are arranged on an inner base plate of a cabin of the cargo hold block, the deck panels are lifted to the cargo hold block, the multiple supporting columns are supported to the positions, likely to deform, of the deck panels, and the multiple deck panels arewelded so that the deck panels can be connected to form a deck block on the cargo hold block. The multiple supporting columns are arranged on the inner base plate of the cabin of the cargo hold blockin advance, the supporting columns are supported to the positions, likely to deform, of the deck panels, after the deck panels are lifted and welded and a lengthened row is disassembled, an extra effective supporting structure is arranged for supporting the deck blocks, the phenomenon that the assembled and formed deck block sinks and deforms is effectively avoided, the horizontal precision of the deck surface of the deck block is ensured, the building precision of a later hatch coaming is improved, repairing and correcting workloads are reduced, and the machining speed is increased.

The invention relates to the technical field of industrial automation equipment, and discloses a plate straightening device capable of reducing wear and avoiding clogging, which includes a base, a rubber ball connected to the inside of the support plate, and a metal ball arranged at the right end of the right slide arm to support the A metal sheet corresponding to the metal ball is arranged inside the plate, a tailgate is connected to the lower side of the outer end of the lifting and retracting rod, and a second spring is connected between the rear end of the arc-shaped guide rod and the lifting and retracting rod. By passing through one end of the inclined plate and facing the through hole first, the space range of the through hole pumping air is reduced, the air flow velocity at the lower side of the through hole is accelerated, and the accelerated airflow pushes the rubber ball to slide in the chute, and the rubber ball drives the slide. The metal ball on the arm is in contact with the metal sheet, and the lifting and retracting rods on the upper right and lower left begin to stretch out to straighten the board. This structure solves the problem that the board straightening device of the existing industrial automation equipment cannot adjust the board. The problem of low level and work efficiency.

The invention relates to the field of vertical lathes, in particular to a multi-column multi-tool high-efficiency composite machining center, comprising a beam, a column and a worktable, and a column lifting assembly is arranged between the beam and the column, and is characterized in that the column is 4-8 They are evenly arranged on the periphery of the worktable in the form of extremely symmetrical distribution; the worktable is provided with a central column in the center, and a central beam sleeve is arranged on the central column, and the central beam sleeve is connected with the lifting assembly of the central column. The flange is connected to the center beam sleeve, the lifting and lowering of the beam, the lifting and lowering of the boring and milling head on the beam, the horizontal movement of the boring and milling head and the turning tool holder, the column retraction operation of the column, and the rotation of the worktable are controlled by the numerical control system respectively. . Compared with the prior art, the beneficial effects of the present invention are as follows: equipped with different tools and accessories, it can realize five functions of gantry boring and milling, gear milling machine, radial drill, vertical turning and floor boring and milling, and becomes an efficient and multifunctional machine. The compound vertical lathe doubles the processing efficiency.

Provided is a glass location vacuum pad assembly and use method. A glass location vacuum pad is formed by a pad body, an upper vacuum cavity, a lower vacuum cavity, an upper vacuum channel, a lower vacuum channel, an upper connector, a lower connector, a first annular sealing groove, a second annular sealing groove and O-shaped sealing ring pads. The pad body is cast to be of an I-shaped structure, the cylindrical upper vacuum cavity is processed in the middle of the upper portion of the pad body, the cylindrical lower vacuum cavity is processed in the middle of the lower portion, at least two annular sealing grooves are formed in the upper plane and the lower plane of the pad body, and the O-shaped sealing ring pads are installed in the annular sealing grooves correspondingly.
