Furthermore, the worktable and tool magazine do not require separate drive units, saving space for installing drive units. At the same time, the worktable and tool magazine can be simultaneously driven, significantly improving the ease of operation of the worktable and tool magazine. Furthermore, since the worktable and tool magazine are driven by the same drive unit, the possibility of movement interference that may arise when separate drive units are provided is eliminated.The shared use of the B-axis work table and tool magazine also helps reduce manufacturing and labor costs while improving workpiece machining efficiency.

Accordingly, the positioning accuracy of the tool on the spindle 61 can be ensured after the tool replacement. The positional correspondence between the spindle 61 and the worktable 5 ensures the machining accuracy of the tool mounted on the spindle 61 relative to the workpiece on the worktable 5, thereby ensuring the quality of the workpiece machining to meet the production requirements.By providing a plurality of 61 spindles and a plurality of 7 tool groups, mass tool replacement and tool pick-up operations can be performed, and machining of a large number of workpieces can be performed simultaneously, thereby increasing the production volume per batch, improving the efficiency of batch production, and further enhancing the economic benefit.

[0031] Preferably, as shown in Fig. 1, a plurality of spindles 61 are arranged in the Y-axis direction, and the axes of the spindles 61 are parallel to the X-axis.

As a result, the A-axis rotary unit 1 can move along the X-axis, approaching or moving away from the A-axis rotary unit 6, thereby adjusting the distance between the B-axis rotary unit 1 and the A-axis rotary unit 6. Providing the B-axis support member 12 increases the flexibility of adjusting the distance between the B-axis rotary unit 1 and the A-axis rotary unit 6.

[0034] Preferably, the support member 12 along the B axis comprises a support portion 13, a mating portion 14 located opposite the support portion 13, and a connecting portion 15 provided between the support portion 13 and the mating portion 14,

The C-axis workpiece housing 16 has a polygonal structure. In this example, the C-axis workpiece housing 16 has a rectangular box-shaped structure having four side surfaces.One surface acts as a machining surface 2, on which a working table 5 is mounted, and each of the remaining three surfaces acts as a tool magazine surface 3, on which a tool magazine 4 is mounted. The mating portion 14 is configured to provide an upper support for the rotary unit 1 along the B axis. The arrangement of the connecting portion 15 with the support portion 13 and the mating portion 14 not only increases the structural rigidity of the rotary unit 1 along the B axis, but also provides a stable support for the rotation of the rotary unit 1 along the B axis, thereby ensuring the stability of rotation of the rotary unit 1 along the B axis.

[0036] Preferably, the bed 8 is provided with an auxiliary positioning portion 17, wherein the auxiliary positioning portion 17 is provided with an auxiliary guide 18, the bed 8 is provided with an X-axis guide 19, the auxiliary guide 18 is parallel to the X-axis guide 19 and is located in a different position along the Y-axis from the X-axis guide 19, the connecting portion 15 is mounted on the auxiliary guide 18 by means of the first slider 20, and the supporting portion 13 is mounted on the X-axis guide 19 by means of the second slider 21.By providing the second slider 21 and the guide 19 along the X axis, the support element 12 along the B axis, that is, the body 16 for the workpiece along the C axis, can move along the guide 19 along the X axis, thereby providing the possibility of adjusting the distance between the working table 5 and the rotary unit 6 along the A axis, as well as the distance between the tool magazine 4 and the rotary unit 6 along the A axis, which increases the convenience of adjusting the positional interaction of the working table 5 and the tool magazine 4 relative to the spindle 61. The interaction between the auxiliary guide 18, the first slider 20, the guide 19 along the X axis and the second slider 21 facilitates the movement of the support element 12 along the B axis and the rotary unit 1 along the B axis along the guide 19 along the X axis.

[0037] Preferably, in the body 16 for the workpiece along the C axis, a drive unit along the C axis is provided, configured to drive the working table 5. The drive unit along the C axis is configured to provide a drive force for rotating the working table 5.

[0038] The specific operation process of the horizontal machine tool disclosed in the present invention is as follows.

[0039] First, a workpiece to be machined is mounted on the work table 5 by means of an automated tooling fixture. An external force drives the support portion 13 to slide along the guide rail 19 along the X-axis, causing the A-axis rotary unit 1 to slide along the guide rail 19 along the X-axis to move closer to or further from the A-axis rotary unit 6, thereby adjusting the positional interaction between the B-axis rotary unit 1 and the A-axis rotary unit 6. Next, the B-axis rotary table 11 is rotated, thereby causing the C-axis workpiece housing 16 to rotate around the B-axis. As the C-axis workpiece housing 16 rotates, the tool magazine surface 3 provided thereon rotates accordingly, and therefore the tool magazine 4 rotates together with the tool magazine surface 3. The tool magazine 4 rotates in the direction corresponding to the spindle 61 of the rotary unit 6 along the axis A.Then, the position of the column 9 is adjusted in the direction of the Z axis, and the position of the carriage 10 is adjusted in the direction of the Y axis, so that the spindle 61 is adjusted to a position corresponding to the tool in the tool magazine 4. Then, the spindle 61 rotates to grip the tool. Thus, the rotary table 11 along the B axis and the housing 16 for the workpiece along the C axis are again set in rotation, rotating the working table 5 in the direction of the spindle 61. Then, the positions of the column 9 and the carriage 10 are adjusted, while simultaneously adjusting the position of the rotary unit 1 along the B axis, so that the position of the working table 5 corresponds to the spindle 61. Finally, the rotary unit along the C axis in the housing 16 for the workpiece along the C axis causes the working table 5 to rotate, and consequently, the working table 5 causes the workpiece to rotate. The tool mounted on the spindle 61 rotates around the A axis to perform machining on the workpiece.
