Hole automatic alignment device for numerical control machining center

Abstract

The invention provides a hole automatic alignment device for a numerical control machining center, and belongs to the technical field of numerical control machining. The hole automatic alignment device comprises a clamping and rotating device, a moving device and a controller. A connecting rod and a clamp block are arranged at the top of the clamping and rotating device, a supporting disc is mounted at the bottom of the clamping and rotating device through multiple supporting columns, a first motor is fixedly arranged at the top of the supporting disc, and a first rotating shaft is driven by the first motor to rotate. The first rotating shaft is fixedly connected with a moving plate in the moving device, a long strip through groove is formed in the top of the moving plate, a gear and a rack which are in cooperation are arranged in the long strip through groove, a second motor is arranged at the top of the moving plate, a second rotating shaft fixed with the second motor is driven by the second motor to rotate, and then device moving is drive. A fixed disc is fixedly arranged on the second rotating shaft, a testing rod is fixedly arranged at the bottom of the other end of the fixeddisc, and a lever meter is arranged on the testing rod. The controller controls the lever meter, the first motor and the second motor. By means of the device, hole alignment can be achieved rapidly and automatically, alignment time can be shortened, and machining efficiency can be improved.

Description

technical field [0001] The invention relates to the technical field of numerical control machining, in particular to a hole system automatic alignment device for a numerical control machining center. Background technique [0002] When the CNC machining center processes the parts, it needs to determine the actual position of the parts on the processing table, so the parts need to be aligned. When aligning the center of the hole system, in order to make the axis line of the spindle coaxial with the axis line of the hole system, first clamp the lever gauge on the machine tool spindle, lower the machine tool spindle, and make the test rod of the lever gauge coincide with the hole on the workpiece Fit the inner wall of the system, and then turn the lever table to find the axis line by bisecting. [0003] The existing hole system alignment method is relatively complicated, and the manual operation is not accurate enough; at the same time, it takes a long time for alignment, which...
