Workpiece adjusting measuring mechanism for machine tool and milling machine with same

Abstract

The invention discloses a workpiece adjusting measuring mechanism for a machine tool. The mechanism comprises first and second adjusting measuring mechanisms mounted in opposite two sides of a worktable of the machine tool. The two adjusting measuring mechanisms comprise mounting racks, feeding units and pressure plates. The pressure plates are matched with the mounting racks through guide pillarsslidably, the feeding units are connected to the pressure plates and are driven by a machine tool control system to drive the pressure plates to feed oppositely to adjust the workpiece position on the worktable of the machine tool, and the control system calculates the dimension of the workpiece according to the initial distances and displacements of the pressure plates. By feeding the two adjusting measuring mechanisms, the pressure plates of the adjusting measuring mechanisms can push the workpiece to the worktable automatically, and meanwhile, the dimension of the workpiece can be measuredsmoothly according to the feeding amounts and the initial distances of the pressure plates.

Description

technical field [0001] The invention relates to a machine tool, in particular to an adjustment and measurement mechanism for a machine tool and a milling machine with the mechanism. Background technique [0002] In the field of mechanical processing, it is often necessary to place the workpiece to be processed in the center of the workbench to perform symmetrical processing on the periphery of the workpiece, such as a milling machine. But at present, placing the workpiece accurately at the center of the workbench is a relatively large technical problem. One solution is to use blanks with a large machining allowance, place the workpiece roughly in the center of the table, and then cut off the errors around it by cutting. This method may achieve the technical purpose, but the waste is serious. [0003] In the prior art, some double-sided milling machines have the ability to automatically correct the workpiece to the center of the worktable. A push plate is installed on the mi...

Problems solved by technology

However, this kind of push plate mechanism is installed on the milling head, and the movement of the milling head is often realized by the transmission of the motor and screw mechanism. Due to the limitations of manufacturing costs, mechanical installation and other reasons, the specifications of the motor and screw are often not do too big

When correcting large workpieces, the power of the milling head movement is often not enough to get enough pressure on the push plate to correct the material
