4results about How to "Avoid multiple clamping" patented technology

The utility model discloses a general section bar hole site auxiliary processing device, which comprises a base plate, a positioning pressure plate and a pressure plate, the base plate is provided with a plurality of positioning holes and a plurality of threaded holes, the plurality of positioning holes are linearly distributed, the plurality of threaded holes are also linearly distributed, the straight lines formed by the plurality of positioning holes and the plurality of threaded holes are parallel to each other, positioning pins are inserted in the positioning holes, and the pressure plate is arranged on the base plate. The positioning pressing plate is positioned through the positioning pin, a to-be-machined part is clamped on the bottom plate, the bolt penetrates through the through hole in the pressing plate to be matched with the threaded hole in the bottom plate, and the to-be-machined part and the positioning pressing plate are fixed on the bottom plate; the device has the advantages that positioning and locking are achieved, high precision is guaranteed, and parts are effectively prevented from deviating in the machining process; the efficiency is improved through one-time installation, hole site machining can be completed only through one-time installation, repeated clamping of parts is avoided, installation errors caused by repeated clamping are reduced, meanwhile, the tool has universality, hole site machining can be carried out on the same profile only by replacing the positioning pressing plate, and the tool machining cost can be saved.

The utility model relates to the technical field of clamp, and disclose a kind of grinding processing positioning fixture for large workpiece, including operation platform, the both ends of operation platform are slidably connected with two mobile supports, and the top of mobile support is equipped with installation groove, and the inside of installation groove is installed with mounting block, and the one end of mounting block is fixedly connected with chuck device, and the both sides of mounting block are equipped with circular groove, and the inside of circular groove is fixedly connected with first spring, and the other end of first spring is fixedly connected with connecting block, and the both sides of mobile support are equipped with circular perforation, and the surface of connecting block is slidably connected with the inside of circular perforation.The grinding processing positioning fixture for large workpiece can allow user to freely select different specifications of chuck device according to the shape of workpiece and processing task, which can avoid processing step adjustment or multiple clamping caused by mismatch of chuck device, thereby simplifying processing procedure and improving production efficiency.

The utility model belongs to the technical field of ship machining, and provides a sawing and drilling compound machine which comprises a machine table, a machining base and a sliding base are arranged on the front portion and the rear portion of the machine table respectively, a lifting frame is arranged on the sliding base towards the machining base, and a drilling machine and a rotatable cutting disc are arranged on the left position and the right position of the lifting frame respectively. The machining base is provided with a round hole and a section groove corresponding to a drilling shaft and a cutting disc of the drilling machine, and the machining base is provided with a left clamping assembly and a right clamping assembly. The clamping assembly clamps the workpiece, the lifting frame moves downwards, after the lifting frame moves downwards to the lowest position, the drilling shaft and the cutting disc complete drilling and cutting of the workpiece at the same time, due to the fact that the drilling shaft is located on the left side of the cutting disc, that is, round holes exist in the cut part of the workpiece, then the lifting frame moves upwards to the initial position, the clamping assembly loosens the workpiece, and the workpiece is cut. And then the workpiece is moved rightwards by the required distance, the clamping assembly clamps the workpiece again, and the workpiece is prepared to be machined again.

The utility model relates to processing center technical field discloses a kind of processing center of multidirectional processing, including main component, including rack, be provided with main shaft box on the rack, the flange plate is fixed in main shaft box bottom, clamping mechanism is provided in main shaft box, reversing seat is provided in the rack side, side cutter is provided in the reversing seat side, workbench is provided below the rack;Installation component is located below the main shaft box, including mounting piece.The utility model has the beneficial effects that: additional lateral tool holder is added in processing center, and lateral tool head is set on the side of tool holder, main shaft box is connected with tool holder, the rotation direction of main shaft is realized right-angle conversion by transmission inside tool holder, the rotary power of main shaft is transmitted to side cutter, drives its rotation, to workpiece side surface is processed, without changing workpiece clamping position, avoid multiple clamping and tool setting operation, shorten processing auxiliary time, to improve processing efficiency.
