Horizontal numerical control drill press with double main shafts

Abstract

The invention discloses a horizontal numerical control drill press with double main shafts and relates to application of the three-axis numerical control technology for simultaneously machining holes,at the same position, of two workpieces at a time. The horizontal numerical control drill press with the double main shafts is composed of the fiver parts of a machine tool body A, a drilling systemB, a hydraulic clamping device C, a control system D and a cooling system E. The two workpieces are clamped and loosened through the hydraulic clamping device, the control system D completes control over the movement of the two workpieces installed on the machine tool body A, the machining positions are found and sent to the drilling system to complete a drilling task, and the cooling system E provides cooling liquid and cools cutters through center outlet water. The horizontal numerical control drill press with the double main shafts can be widely applied to the drilling machining technologyof prestress products and can simultaneously machine holes, at the same position, of the two workpieces at a time, central outlet water is adopted for cooling, the cooling effect is good, the drillingfeeding speed can be greatly improved, and the service life of the cutters can be greatly prolonged; and as horizontal drilling is adopted, drilling scraps can be cut and fall easily through self-gravity, the drilling scraps are convenient to discharge, and the production efficiency can be greatly improved.

Description

technical field [0001] The patent of the present invention relates to a new type of numerical control equipment used in drilling technology, in particular to a horizontal double-spindle numerical control drilling machine used in the drilling of porous cylindrical anchors. Background technique [0002] At present, the porous anchors in the prestressed products are drilled one by one with a vertical single-axis CNC drilling machine. The production efficiency is not high and it is difficult to remove the drilling chips. In addition, the external cooling is used, and the service life of the tool is short. The porous anchor holes in the prestressed product have multiple identical holes in a honeycomb shape on a workpiece. At the same time, as a stressed part, the drilling depth is relatively deep. Application number 201611108696.5 discloses an automatic drilling with double rotary table and double drill floor The machine includes a workbench, which is provided with two identical ...

Problems solved by technology

Each turntable can be loaded with 12 blank workpieces, which can realize automatic control and simple operation. The operator only needs to complete the loading and unloading of blank workpieces and press the start button to complete the clamping of a total of 24 blank workpieces on two turntables at one time. It works with drilling, but each spindle drill can only drill a hole in one position on the workpiece. It is impossible to drill holes in multiple positions on a workpiece. Due to the limitation of the turntable, it can only process small diameters and partial thicknesses. thin workpiece

[0003] Application number 201320303155.3 discloses a dual-axis CNC drilling machine for automobile brake drums, which includes a machine table, two CNC slide tables, two CNC indexing turntables and two drilling power heads with CNC slide tables. There is a column on the rear side of the table, and two linear slide rails are provided on the upper front side of the machine table. The two CNC slide tables are slidably arranged on the linear slide rails, and the There is a linear drive device that drives the CNC sliding table to slide; two vertical frames are arranged in parallel on the front side of the column, and each vertical frame has a drilling power head that can slide vertically in it. The top of the vertical frame has a The vertical drive device that drives the movement of the drilling power head satisfies the simultaneous processing of two jobs, but the patent uses two CNC slide tables, two CNC indexing turntables and two drilling power heads with CNC slide tables. To use a numerical control system that can control six axes, six servo motors and six servo motor drivers must be used, so the manufacturing cost is very high, and external cooling is used, and the drilling feed rate is limited and cannot be increased.
