Description

Compound machine tool

The invention provides a compound machine tool which is related to the structure of an automatically controlled machine tool.

A general automatic control lathe has two forms, as shown in Fig. 1 is a pass type lathe 10, which is mainly provided with a rotatable main shaft 12 on a machine table 11, which is provided for gripping a workpiece, and The machine table 11 has a machine tool 13 on which a tool chuck holder 14 is displaceably disposed. The tool holder holder 14 is provided with a fixed plurality of tools and can be linearly displaced on the machine tool 13, and is processed during processing. The spindle 12 drives the workpiece to rotate, and the tool chuck seat 14 translates and cuts the workpiece according to the processing requirement; while the cutting process, the workpiece chip is directly dropped on the machine tool 13, and the continuous accumulation of chips will directly Affects the displacement of the tool holder 14 and affects the precision of the machining or the range of machining, which leads to the lack of processing limitations. In addition, as shown in Fig. 2, a walking type lathe 20 is mainly used in one machine. The table 21 is provided with a spindle 22, which can position the workpiece, and the spindle 22 is further matched with the guide sleeve 221 for guiding the workpiece to be displaced in the Z-axis direction, and the machine 21 is further provided with a plurality of cutter units 23, each cutter Unit 23 can be a panel on the machine The displacement in the X-axis direction and the Y-axis direction is performed, and the chips generated by the machining are directly dropped in the space 24 below the machine table 21. The movement of the tool unit 23 and the workpiece is completely unaffected, however, the tool units 23 are only Can perform translational actions, but not for special tilting The oblique processing results in the lack of processing applicability; as can be seen from the above, the two conventional lathes have different characteristics and defects, and the inventors have long been engaged in research and deeper conceiving in the field. After many trials and developments, a composite machine tool was finally invented.

The invention provides a compound machine tool whose main purpose is to improve the processing applicability of the machine tool.

To achieve the foregoing objective, the present invention provides a compound machine tool comprising: a machine table, slidably disposed with a spindle seat for clamping a workpiece and capable of feeding a workpiece with a power feeding device; a tool head seat is disposed on the machine table, and a first tool holder is fixedly disposed on the tool head seat, the first tool holder has a plurality of sipe for positioning a different first tool, and the tool head seat is Further, a second tool holder is disposed, the second tool holder has a tool collet for positioning and positioning a second tool, the tool collet drivingly connecting a tool driving source to drive the tool collet to drive the second The tool turns.

By using the turning tool and the second tool respectively arranged on the tool head seat to perform different tool processing, the processing type is increased, and the machine table is further matched with the spindle seat capable of gripping the feeding workpiece, thereby reducing the working range. The restrictions increase the added economic value of the machine tool.

In order to enable your review committee to have a better understanding and understanding of the purpose, features and effects of the present invention, please refer to the following [simplified description of the drawings] for details: A preferred embodiment of the compound machine tool of the present invention, as shown in FIGS. 3 to 7, includes: a machine table 30, a first spindle seat 31 and a second spindle seat 32 are slidably disposed, and the first spindle seat 31 is disposed opposite to the second spindle holder 32. The first spindle holder 31 and the second spindle holder 32 are configured to clamp a workpiece, and the first spindle holder 31 and the second spindle holder 32 respectively cooperate with a power feed. The device 311, 321 feeds the workpiece, the linear connection direction of the first spindle holder 31 and the second spindle holder 32 is defined as a Z direction, and the vertical direction defines an X direction and a Y direction, the X direction The tool holder 40 is fixedly disposed on the machine table 30 and located between the first spindle holder 31 and the second spindle holder 32, and has a holder rail 41 thereon. The tool holder rail 41 extends in the X direction; a tool head holder 50 includes a first sliding seat 51, a second sliding seat 52, two first tool holders 53, a second tool holder 54, and a tool driving source 55. The first slider 51 has a plurality of first sliders 511, and the first sliders 51 are slidably sleeved on the blade holders A slide rail 512 is disposed on the first slide base 51 in the Y direction; a second second slide 521 is disposed at one end of the second slide 52, and the second slide 521 is Each of the second sliders 521 is slidably disposed on the slide rail 512 of the first slider 51. The first tool holders 53 are respectively disposed on two sides of the second slider 52, and each The first tool holder 53 has a plurality of sipe 531 for positioning a different first tool A, and the first tool A can be a turning tool; The second tool holder 54 is pivotally disposed at an end of the second sliding block 52 different from each of the second sliding blocks 521, and the second tool holder 54 is pivotally coupled to the second tool holder 54 by a pivot 541. The second carriage 54 is connected to the second tool holder 54 and has a cutter collet 542 for positioning the second cutter B, and the second cutter B can be a cylindrical cutter or drill bit; And the tool driving source 55 is drivingly coupled to the tool collet 542 to drive the tool collet 542 to drive the second tool B to rotate.

The above is the structural configuration and features of the composite machine tool of the present invention, and the machine tool is operated by one of the spindle seats 31 for clamping the workpiece and feeding in the Z direction, and then matching the tool head block 50. The first tool A or the second tool B is processed, and the tool head block 50 can be displaced in the X direction by the coordinate of the tool holder rail 41 and the first slider 511 during machining, or by the slide rail 512 and the second slider 521 cooperate with the displacement in the Y direction, thereby knowing that the displacement action of the tool or the workpiece does not interfere with each other, and the chip generated by the processing is directly dropped below the machine table 30. , and is not located on the path of the tool or the workpiece, so that the displacement of the tool and the workpiece is not affected, and can be applied to different processing sizes or shapes without limitation, thereby improving the applicability of the use; The first main shaft base 31 and the second main shaft base 32 are disposed on opposite sides of the machine base 30, and can be fed to the workpiece by the power feeding devices 311 and 321 respectively, so that it can be applied to the cutting of the elongated workpiece; The first spindle seat 31 and The second headstock 32 sandwiched alternately, and with a second carriage 52 on both sides is provided with a first tool-like structure 53 on both ends of the state of a workpiece is machined, machining The convenience is very high; more importantly, the second tool holder 54 of the tool head block 50 is pivotally disposed on the second shoe 52, so that the second tool holder can be pivoted according to processing requirements. The yaw angle of 54 is tilted, which in turn provides a more versatile processing mode and increases the added economic value of the machine tool.
