[0002] As a common machine tool equipment, horizontal machining center plays an important role in modern manufacturing industry. The traditional horizontal machining center usually adopts a single workbench structure, which is simple and reliable, but in actual application, the frequent replacement of workpieces seriously affects the production efficiency. With the continuous improvement of industrial automation, the market demand for efficient and flexible machining equipment is increasing. Therefore, the development of a double workbench horizontal machining center capable of quickly switching workbenches has become a research hotspot.

[0028] In an embodiment of the horizontal machining center structure of the present application, please refer to Figures 1 to 5, the horizontal machining center structure comprises a base 100, a rotary table 200, a column 300 and a horizontal machining mechanism 400. The rotary table 200 is arranged on the base 100, and the column 300 is arranged on the top side of the rotary table 200. The column 300 has at least two side planes 301, each side plane 301 is provided with a linear motor 500, and a workbench 600 connected with the linear motor 500, and each linear motor 500 drives the corresponding workbench 600 to move up and down independently. The horizontal machining mechanism 400 is arranged at one end of the base 100, and the horizontal machining mechanism 400 comprises a saddle 410, a first driving mechanism 420, a spindle seat 430 and a second driving mechanism 440. The saddle 410 is slidably arranged on the base 100, the first driving mechanism 420 is connected with the saddle 410 and used for driving the saddle 410 to translate, the spindle seat 430 is slidably arranged on the saddle 410, the second driving mechanism 440 is connected with the spindle seat 430 and used for driving the spindle seat 430 to move, and the moving direction of the spindle seat 430 is perpendicular to the moving direction of the saddle 410. The spindle seat 430 is provided with a spindle 450. The spindle 450 is used for mounting a cutting tool, and the cutting tool is driven to rotate by the spindle 450 to cut a workpiece on the workbench 600.

[0029] Specifically, the horizontal machining center of the embodiment is first to position the workpiece to be machined on the workbench 600 away from the spindle 440, and the column 300 is driven to rotate by the rotary table 200, so that the workbench 600 clamping the workpiece to be machined is directed to the spindle. The workbench 600 is driven to move up and down by the corresponding linear motor 500, while the other workbench 600 is away from the spindle 440, and the two workbenches 600 are independently lifted up and down. Therefore, when the workbench 600 directed to the spindle 440 is lifted up and down to process the workpiece, the other workbench 600 does not affect the clamping of the workpiece, so that the workpiece on one of the workbenches 600 can be machined while the other workbench 600 can clamp the workpiece, thereby improving the efficiency.

Specifically, referring to Figure 4 and Figure 5 The two groups of horizontal machining mechanisms 400 are arranged side by side at the same end of the base 100, and the saddles 410 of the two horizontal machining mechanisms 400 are connected to the same first driving mechanism 420. Specifically, one group of first driving mechanisms 420 is arranged on the base 100, and the two groups of saddles 410 are connected to the first driving mechanism 420. The same side plane of the column 300 is provided with two groups of independent linear motors 500, and each linear motor 500 is provided with a workbench 600.

[0035] Further, one end of the saddle 410 protrudes from the base 100, and the bottom of the one end of the saddle 410 protruding from the base 100 is provided with an inclined cutout 411.
