Description

Quick positioning tool for numerical control machine tool machining

Technical Field

The utility model relates to the technical field of numerical control machine tools, in particular to a rapid positioning tool for machining of a numerical control machine tool.

Background

In a mechanical milling machine tool, a three-axis (X, Y, Z coordinate axis) linkage numerical control milling machine is still common processing equipment with wider application. Before a triaxial numerical control milling machine processes a part, the reference surface of the processed part is corrected, so that the reference plane of the workpiece and the coordinate plane of a machine tool are aligned to be consistent, and the workpiece is fixed, and then the processing can be started. Since the correction of the workpiece is performed in a stopped state, the stopping is caused, and the longer the stopping time is, the shorter the starting time of the machine tool is, and the lower the effective output of the machine tool is.

In the process of correcting the reference surface of the part, the two conventional tooling methods are as follows.

First, as shown in fig. 1, the machined part 1 is first locked with the tool bottom plate 2 through a tool screw, then transported to the machine tool workbench 3, and the tool bottom plate 2 is pressed by a pressing screw 4 through a cushion block 5 and a pressing plate 6, and then pressed to the workbench 3. Before the workpiece is locked to the workbench, the reference surface of the workpiece is corrected, and the correction process is to lock the screw while correcting the reference surface A of the workpiece through the dial indicator. After the machined part is locked, the workpiece reference surface is required to be consistent with the machine tool coordinate plane or to be within a set tolerance range, and if the workpiece reference surface is not within the tolerance range, the screw is loosened to continue the calibration until the workpiece reference surface is consistent with the machine tool coordinate plane. The tool mode is called a locking plate type tool, has high requirements on technical experience of workers and is time-consuming.

Second, as shown in fig. 2, as the technology of the electromagnetic chuck is mature, the electromagnetic chuck 7 can be mounted on the machine tool workbench 3, the electromagnetic chuck 7 is pressed by the pressing screw 4 through the cushion block 5 and the pressing plate 6, and the machined part 1 is placed on the electromagnetic chuck 7 to calibrate the tool. When the reference surface of the machined part is corrected to the same angle with the coordinate axis of the machine tool, the electromagnetic chuck is electrified and magnetized, so that the workpiece can be sucked tightly to meet the machining state. Compared with the traditional locking plate type tool, the method of the sucker type tool only adopts magnetic attraction force to lock the machined part, and releases the action of manually locking the screw by workers, but the adjustment and the meter correction action of the machined part before the sucker does not conduct magnetism are still time-consuming due to the fact that auxiliary positioning is not carried out.
