On the second workpiece 971, although the conventional method has been used to process small workpieces, although the processing quality and efficiency have been improved, when it is applied to large workpieces, the first workbench 96 or the second workbench 97 When carrying large workpieces, the load will increase, causing the displacement speed of the first workbench 96 and the second workbench 97 to be greatly slowed down, and because the support base 91 is fixed in design, it cannot be displaced, causing the machine head. The tool holder 95 of the unit 94 can only be displaced left and right by the drive of the horizontal drive group 92, without The time required for the first work piece 961 or the second work piece 971 to move to the position below the tool holder 95 cannot be accelerated.

於本實施例中，該第三X軸驅動裝置60具有二分別設於該各立牆40頂面上之第三螺桿63及二分別設於該橫樑50底部對應該各第三螺桿63位置之第三螺帽64，該第三螺桿63用以產生旋轉動力，該第三螺帽64與該第三螺桿63螺接，使當該第三螺桿63正、反向旋轉時，由該第三螺帽64帶動該橫樑50進行X軸向之往復位移。 In the present embodiment, the third X-axis driving device 60 has two third screws 63 provided on the top surface of each standing wall 40 and two third screws 63 provided on the bottom of the beam 50 corresponding to the third screws 63, respectively. A third nut 64, the third screw 63 is used to generate rotational power, and the third nut 64 is screwed to the third screw 63, so that when the third screw 63 rotates forward and reverse, the third screw 63 The nut 64 drives the beam 50 to perform a reciprocating displacement in the X-axis direction.
於本實施例中，該加工主軸70同樣具有一Y軸滑座71、一Z軸滑座72、一主軸頭73、一Y軸驅動裝置74及一Z軸驅動裝置75；惟與前述實施例之主要差異在於：於本實施例中，該Y軸驅動裝置74具有一設於該橫樑50一側之Y軸螺桿743及一設於該Y軸滑座71上對應於該Y軸螺桿743位置，並與該Y軸螺桿743螺接之Y軸螺帽744，使當該Y軸螺桿743正、反向旋轉時，可帶動該Y軸滑座71進行Y軸向之往復位移，該Z軸驅動裝置75具有一固設於該Y軸滑座71一側之Z軸螺帽753及一設於該Z軸滑座72上並與該Z軸螺帽753螺接之Z軸螺桿754，使當該第Z軸螺桿754正、反向旋轉時，亦可同時上下位移而帶動該Z軸滑座72進行Z軸向之往復位移。 In this embodiment, the processing spindle 70 also has a Y-axis slide 71, a Z-axis slide 72, a spindle head 73, a Y-axis drive device 74 and a Z-axis drive device 75; The main difference is that in this embodiment, the Y-axis driving device 74 has a Y-axis screw 743 provided on one side of the beam 50 and a position corresponding to the Y-axis screw 743 provided on the Y-axis slide 71. And a Y-axis nut 744 screwed to the Y-axis screw 743, so that when the Y-axis screw 743 rotates forward and reverse, the Y-axis slide 71 can be driven to reciprocate in the Y-axis direction, the Z-axis The driving device 75 has a Z-axis nut 753 fixed on one side of the Y-axis slide 71 and a Z-axis screw 754 provided on the Z-axis slide 72 and screwed with the Z-axis nut 753, so that When the Z-axis screw 754 is rotated in the forward and reverse directions, the Z-axis slide 72 can also be moved up and down simultaneously to drive the Z-axis slide 72 to perform a reciprocating displacement in the Z-axis direction.
是以，本創作除可同樣達到讓第一工作滑台20或第二工作滑台201與橫樑50進行雙X軸向同時位移之功效外，更能藉由相對便宜之螺桿與螺帽組合取代造價昂貴之磁性定子軌道與動力感應裝置組合，以達到降低製造成本之功效。 Therefore, in addition to achieving the same effect of simultaneously shifting the first work slide 20 or the second work slide 201 and the beam 50 in the double X-axis direction, this creation can also be replaced by a relatively cheap screw and nut combination. The expensive magnetic stator track and power induction device are combined to achieve the effect of reducing manufacturing costs.
