Description

[Detailed Description of the Invention] 1. A kind of single housing or multi-housing, single-row or multi-row, tier or multi-tier work table, fixed gate type or movable gate type special design. It is a double-column machine tool consisting of
It is equipped with one or more sets of adjustable cutting direction turret units on a crossbeam or gate type, and provides horizontal linear movement by means of a driving device, so that horizontal processing can be performed with respect to the workpiece. alms,
Going one step further, we will add intersecting machining operations of different dimensions to the conventional traditional vertical cutting process to avoid the residual stress caused by the workpiece machining, or to cut straight lines or circular arcs at specific angles. Machining the workpiece by performing a circular reciprocating motion, or cutting the workpiece in accordance with the self-rolling motion of the cutlery on the multiple sets of spindle heads on the tool rest while the tool holder makes continuous circular motion. This is to remove the residual stress of a workpiece with a wide machining area in the mixed cutting direction performed by public and automatic wheels.The feature of the horizontal machining work is that the workpiece is fixed. The workbench is moved or the movable gatepost is moved vertically for minute adjustments to feed the cutting and provide a feed, and the cutter on the above-mentioned cross beam performs horizontal cutting. The above linear reciprocating turret can be installed on the cross beam of the traditional gate type or movable turret. The sliding movement on the cross beam guide rail of the above-mentioned linear reciprocating tool post unit, which is moved by a connecting rod, a hollow oil cylinder, or a lead screw, is installed. This method reduces the generation of frictional force through rollers or ball bearings, gas films, oil films, or other sliding effects.It is possible to go further and install one or more sets of blade cutting direction adjustable tool post units. Then, use a conventional mechanical or locking device to fix the tool rest in the home position, and then use a conventional mechanical or oil-operated method to process the cutter on the tool rest in the cutting direction of the previous one. After completion, the spindle head is rotated 90 degrees or rotated at an arbitrary angle to select the cutter on the tool post, rotated to the cutting position, and changed to a different cutting direction. The above processing method can be used to create one set or more than one set of fixed-direction type turret units depending on the horizontal or vertical needs of the turret unit. The vertical and horizontal intersecting processing can be performed automatically by a preset program control device.

General machine tools can only perform simple machining operations, and the metal machining process must be divided into several steps according to the specific functions of the machine tool used for machining, and the machining must be performed sequentially. The inherent physical properties of the material are such that in the forming process of each function, stress and strain are inevitably generated that are mutually exclusive and corresponding to each other, resulting in distortion in the final stage forming process of the workpiece. In addition, replacing the workpiece with a machine tool with a different function wastes time and work, and also increases machining errors. If this occurs, a raised phenomenon remains in the center of the workpiece; a phenomenon in which the workpiece tilts to one side after milling or grinding, etc. The workpiece that has internal stress or distortion will be subject to the following: When cutting is performed during machining work, when replacing and locking the workpiece, or machining in one direction, or replacing related parts on the gatepost, moving parts, operational errors, etc. This causes even more severe distortion and errors in the workpiece.

The present invention has a cantilevered or multi-gate type planing machine cross beam arrangement, and the cross beam and the main axis of the cutter perform linear or circumferential or specific angle or arc-shaped reciprocating motions during the machining process. This is to eliminate distortion in the workpiece by adjusting the residual stress that occurs when processing the workpiece in one direction.

Its characteristic feature is that the gate-shaped or movable gate-shaped traditional mechanism attached to the above-mentioned crossbeam (2) is driven by a movable motor (21).
Alternatively, the above-mentioned blades are driven by other rotary power driving methods, or by pinions, racks, as shown in Figure 2, or by a hollow oil cylinder or a reciprocating unnecting rod driven wire type erinder or lead screw. Base assembly (

Proceeding further, one or more sets of blades are fitted with a turret (3) that can adjust the cutting direction, and the device is fixed thereto with a conventional mechanical or oil-type lock, and the turret unit (3) is fixed with a fixed position lock. After the cutting tool on the tool rest (3) completes machining in the previous cutting direction, the spindle head is moved to 90° or any arbitrary angle using a conventional mechanical method or an oil-operated moving method. In the above horizontal cutting method, the cutter on the tool rest (3) is rotated to a selected cutting position and cut in a different selected direction. Artificial operation (
(as shown in Fig. 3), or by rotating the spindle head to an arbitrary certain angle using a worm, worm gear set (shown in Fig. 4) or a reciprocating connecting rod according to a specific control command. In addition, the tool rest (3) can be reciprocated in a linear manner and the workpiece (1) can be rotated to the desired cutting position.
It is used to move the moving device or movable gate of the workbench (4) to which the work table (4) is fixed and finely adjusted to perform cutting feed and feed operations.

The design in this section goes one step further by making the crossbeam (2) movable in the left-right direction and simultaneously reciprocating the tool rest unit (3) that can adjust the cutting direction of the blade. The cutting direction of the blade is adjusted automatically or manually depending on the relative movement of the two, and the blade is moved while forming a vector composite locus.
