New description: [New technical field] This creation is about a lathe, especially for a cross-back composite lathe with multiple machining axes. [Prior Art] In order to improve the processing quality and processing efficiency of the machined parts, today's lathes are mainly made up of eight computer numerical control (CNC) lathes. These types of lathes are generally referred to as CNC lathes. In a composite lathe, it usually includes: the bottom bed, the spindle head, and the turret processing. The following is a simple 5 brothers on the processing procedure of the composite lathe to the workpiece. The rhyme firstly sends the workpiece to be machined to the spindle head of the driving lathe by the feeding system or the operator, and the automatic chuck on the spindle head is used to clamp the end of the workpiece to be processed. Next, the machining is performed by a turret processing system, for example, drilling one end of a cylindrical workpiece. And the completion of a piece usually requires multiple passes. In order to achieve a fascinating process, the turret-assisting system is typically able to move in multiple machining directions, thereby processing the various faces of the garrison. However, in the knives of the general-purpose lathe, it usually consists of a first-to-second machining axis and a third machining sleeve with an angle to the first or the first working axis. The three machining axes are: and the other of the second machining axes is perpendicular to each other. For example, the third machining axes are mutually coupled; the shaft clamp is provided with an angle 'and the third machining axis and the first machining axis 4 1V1W^316. In the above example, when the composite lathe is intended to be perpendicular to the first machining vehicle and perpendicularly When the other machining axis is machined in the other direction, the driving device of the second and second machining axis directions is simultaneously driven to complete the above processing. A disadvantage of the above design is that the driving speeds of the driving means of the driving means for simultaneously driving the two machining axes must match each other, and the desired machining result cannot be produced once the speed of the speed is erroneous. In addition, the complexity of writing the control program of the drive device is relatively high, so the probability of error is relatively high. Therefore, it is necessary to redesign a composite lathe that can overcome the above disadvantages. [New content] Therefore, the purpose of this creation is to provide a hatchback composite lathe that utilizes the design of multiple axes perpendicular to each other to reduce the complexity of the control of the drive unit in the hatched back lathe, thereby reducing the drive unit.

The first drive unit is movable in the direction of the first machine axis, wherein the first machine axis is perpendicular to the vertical axis of the bed and the second drive is movable in the direction of the 5 M405316 second machine axis. The third driving device is movable in a direction of the third machining axis, wherein the third machining axis has a predetermined angle with the vertical axis of the bottom bed, and the first to third machining axes are perpendicular to each other . Further, the first turret is driven by the first to third driving means to process the workpiece. According to another embodiment of the present invention, in the above-described hatched back lathe, the predetermined angle is 10 to 20 degrees. According to still another embodiment of the present invention, in the above-described hatchback composite lathe, the bottom bed has a joint side, wherein an angle between a vertical normal line of the joint side and a vertical axis of the bottom bed and the predetermined angle is It is 90 degrees and the above spindle head is fixed to the joint side. The advantage of this creation is that the design of the turret processing system can be moved along a plurality of mutually perpendicular processing axes, thereby reducing the complexity of the control of the driving device in the oblique-back composite lathe, thereby improving the output of the inclined-back composite lathe. The yield of the workpiece. Another advantage is that the specific machining axis in the turret processing system and the vertical axis of the bottom surface of the bottom composite lathe are provided with a predetermined angle, so that the turret in the turret processing system is relatively far away from the slant. The operator of the back type compound lathe can reduce the operator's psychological pressure and can also take care of the operator's convenience in handling the workpiece held by the spindle head.

In this embodiment, as shown in FIG. 1B, the turret processing system • 200” and the other spindle head 1〇4 are further included. ', where the turret processing system 2〇〇, the drive unit and the turret and the spindle head 1〇4 Are disposed on said bed 1〇2. The arrangement of the other spindle head 104' is mainly for processing the other end of the workpiece held by the spindle head 104. As for the setting of the turret processing system and the 200", in addition to the processing of the workpiece held by the spindle head 1〇4, the workpiece held by the other spindle head 104' can be processed. After referring to the contents disclosed in this specification, φ can be changed for the above application according to the functions required for the hatched back lathe 100. In a specific embodiment, the hatchback compound lathe is 1〇. The crucible may include another bed (not shown) different from the bed 102 for securing the turret processing systems 200 and 200" and another spindle head 1"4'. However, in order to play an additional turret The maximum power month b of the machining systems 200' and 200" and the other spindle head 1〇4, at this time the turret processing system 2', the turret processing system 200" and the other spindle head 104' and the bottom bed 1 The relative position between the crucibles 2 is such that each of the driving devices, each turret and the other main spindle head 104 are located on one side of the bottom bed 1〇2 or above the bottom bed 102, so as to facilitate the spindle head 1 The workpiece M405316 clamped by 〇4 is machined, or in the spindle head 104 and the spindle head 104' The processing unit is transferred. Therefore, the scope of the patent application listed below is intended to include the embodiment. In this embodiment, as shown in FIGS. 1B and 1C, the first driving device 204 and the second driving device 206 and The third driving device 208 includes the servo motor 212 and the linear sliding rail 214, respectively, but is not limited thereto. In other embodiments, the first driving device 204, the second driving device 206, and the third driving device 208 may be servo-coated. The motor and the common ball screw, wherein the ball screw is used to replace the above-mentioned linear slide 214. In other embodiments, the first φ drive 204, the second drive 206, and the third drive 208 may respectively contain oil. The above-mentioned related art is a common knowledge well-known in the technical field, and thus is not disclosed in detail herein. Although the present invention has been disclosed in the above embodiments, it is not intended to limit the creation, any familiarity. This artist can make various changes and refinements without departing from the spirit and scope of this creation. Therefore, the scope of protection of this creation should be attached to the scope of patent application. φ [Simple description of the schema] In order to have a better understanding of the idea of this creation, please refer to the above detailed description and the corresponding diagram. It should be emphasized that according to the standard of industry, the drawing t The various features are not shown to scale. In fact, the dimensions of the various features may be arbitrarily enlarged or reduced for the purpose of clearly illustrating the above embodiments. The related drawings are described below.
