[0024] As shown in FIG. 1, Figure 1As shown, the structure and working principle of the second horizontal machining center 102 of this embodiment are exactly the same as those of the first horizontal machining center 101. The second horizontal machining center 102 includes a second column, a second spindle SP2, a second X-axis moving assembly, a second Y-axis moving assembly and a second Z-axis moving assembly. A tool 1042 is installed on the second spindle SP2, and the tool 1042 is driven by the second spindle SP2 to process the workpiece 105.

[0025] like Figure 5 As shown, the tool magazine 104 of this embodiment includes a tool holder 1041, a clamping assembly, and a tool 1042. A set of clamping assemblies is provided on both sides of the tool holder 1041. The tools 1042 on the two sets of clamping assemblies are used by the first horizontal machining center 101 and the second horizontal machining center 102, respectively. The clamping assembly includes a plurality of fixtures 1043 arranged at equal intervals along the Y-axis direction, and a tool 1042 is placed in each fixture 1043. The specific number of tools 1042 is set according to the processing steps such as milling, drilling, and tapping. Different processes require different tools 1042. In this embodiment, two groups are provided, with a total of 8 tools 1042 in each group. In this embodiment, a linear tool magazine 104 is used to change tools for two horizontal machining centers. Compared with the traditional solution of each horizontal machining center being equipped with a rotary tool magazine 104, the space occupied by the machine tool body is very small, which greatly reduces the volume of the machine tool body and increases the space of the processing area.

[0026] Example 2 like Figure 7 As shown, this embodiment provides a method for controlling a head-to-head horizontal machining center, which includes the following steps: Step S1: establishing a first path processing program for the first horizontal machining center 101, the first path processing program being used to control the first horizontal machining center 101 to process the workpiece 105; establishing a second path processing program for the second horizontal machining center 102, the second path processing program being used to control the second horizontal machining center 102 to process the workpiece 105; storing the first path processing program and the second path processing program in a program memory of the CNC, respectively; and establishing a tool management mechanism; Step S2: The rotary table 103 drives the workpiece 105 to rotate, rotating the front side of the workpiece 105 to face the first spindle SP1 of the first horizontal machining center 101, and rotating the back side of the workpiece 105 to face the second spindle SP2 of the second horizontal machining center 102; Step S3: simultaneously start the first path processing program and the second path processing program, and use the first horizontal machining center 101 and the second horizontal machining center 102 to process the front and back sides of the workpiece 105 simultaneously; Step S4, when the front and back surfaces of the workpiece 105 are both finished, the rotary table 103 rotates the workpiece 105 by 90°; Step S5, the first-path machining program controls the first horizontal machining center 101 to machine the left side surface of the workpiece 105, while the second-path machining program controls the first horizontal machining center 101 to machine the right side surface of the workpiece 105.

[0027] Step S6, when the left and right side surfaces of the workpiece 105 are both finished, the machining process of the workpiece 105 is ended.

[0028] The first-path machining program of the embodiment specifically includes the following steps: Step S111, input the position coordinates of the workpiece 105; Step S112, move the first spindle SP1 of the first horizontal machining center 101 to a safe position, and wait for the second spindle SP2 of the second horizontal machining center 102 to also move to a safe position; because the position angle of each batch of workpieces 105 on the rotary table 103 is not fixed before machining, the rotary table 103 needs to rotate the front surface of the workpiece 105 to face the first spindle SP1 of the first horizontal machining center 101, and rotate the back surface of the workpiece 105 to face the second spindle SP2 of the second horizontal machining center 102, and then the machining can be performed, in order to prevent the workpiece 105 from colliding with the first and second spindles SP1 and SP2 during rotation, the first and second spindles SP1 and SP2 need to be moved to a safe position first, and then the workpiece 105 is rotated. There is a certain difference in machining speed between the two horizontal machining centers, so the two horizontal machining centers need to wait for each other, and only after the two horizontal machining centers are both moved into position, the rotary table 103 starts to rotate.

[0029] Step S113, when the front surface of the workpiece 105 is rotated into position, the first spindle SP1 of the first horizontal machining center 101 performs machining operation on the front surface of the workpiece 105, and during the machining, tool changing operation is performed according to the machining requirements of the workpiece 105, and the tool changing operation is based on a tool management mechanism; Step S114, after the front surface of the workpiece 105 is machined, the second spindle SP2 of the second horizontal machining center 102 waits for the back surface of the workpiece 105 to be machined; Step S115, when the front and back surfaces of the workpiece 105 are both machined, the first spindle SP1 of the first horizontal machining center 101 is moved to a safe position, and the second spindle SP2 of the second horizontal machining center 102 is also moved to a safe position; Step S116, when the rotating workbench 103 rotates the workpiece 105 by 90°, the first main shaft SP1 of the first horizontal machining center 101 performs machining operation on the left side surface of the workpiece 105, and the tool changing operation is performed according to the machining requirements of the workpiece 105 during the machining operation, and the tool changing operation is based on the tool management mechanism; Step S117, after the machining of the left side surface of the workpiece 105 is completed, the second main shaft SP2 of the second horizontal machining center 102 waits for the machining of the right side surface of the workpiece 105 to be completed.

[0030] The second path machining program of the embodiment specifically includes the following steps: Step S121, input the position coordinates of the workpiece 105; Step S122, move the second main shaft SP2 of the second horizontal machining center 102 to a safe position, and wait for the first main shaft SP1 of the first horizontal machining center 101 to also move to a safe position; Step S123, when the back surface of the workpiece 105 is rotated in place, the second main shaft SP2 of the second horizontal machining center 102 performs machining operation on the back surface of the workpiece 105, and the tool changing operation is performed according to the machining requirements of the workpiece 105 during the machining operation, and the tool changing operation is based on the tool management mechanism; Step S124, after the machining of the back surface of the workpiece 105 is completed, the first main shaft SP1 of the first horizontal machining center 101 waits for the machining of the front surface of the workpiece 105 to be completed; Step S125, when the front surface and the back surface of the workpiece 105 are machined, the second main shaft SP2 of the second horizontal machining center 102 is moved to a safe position, and the first main shaft SP1 of the first horizontal machining center 101 is also moved to a safe position; Step S126, when the rotating workbench 103 rotates the workpiece 105 by 90°, the second main shaft SP2 of the second horizontal machining center 102 performs machining operation on the right side surface of the workpiece 105, and the tool changing operation is performed according to the machining requirements of the workpiece 105 during the machining operation, and the tool changing operation is based on the tool management mechanism; Step S127, after the machining of the right side surface of the workpiece 105 is completed, the first main shaft SP1 of the first horizontal machining center 101 waits for the machining of the left side surface of the workpiece 105 to be completed.

[0031] The tool management mechanism of the embodiment specifically includes the following steps: As shown in Figure 8 , 9 Each tool 1042 in each clamping assembly is numbered from top to bottom along the Y-axis direction, and the tool number of each tool 1042 is set to 1-n, n is an integer greater than 1, and in the embodiment, n=8. The spacing of every two tools 1042 in the Y-axis direction is G. The tool change point F of the first tool 1042 is used as a reference point, and a tool change reference point E is set. The distance between the tool change reference point E and the tool change point F of the first tool 1042 in the Z-axis direction is M, and the distance between the tool change reference point E and the tool change point F of the first tool 1042 in the Y-axis direction is N; After the tool change operation is started, the first spindle SP1 or the second spindle SP2 is first moved to the tool change reference point E, and then the first spindle SP1 or the second spindle SP2 is moved downward along the Y axis by a distance L according to the tool number n of the tool 1042 currently on the first spindle SP1 or the second spindle SP2. , then move the first spindle SP1 or the second spindle SP2 along the Z-axis direction toward the corresponding fixture 1043 by a distance M, and finally return the tool 1042 currently on the first spindle SP1 or the second spindle SP2 to the corresponding fixture 1043, completing the tool return operation. For example, assuming the current tool 1042 on the spindle is the first tool 1042, first move the spindle to the tool change reference point E, then move the spindle downward along the Y-axis direction by a distance L, where L=N, and then move the spindle along the Z-axis direction toward the fixture 1043 of the first tool 1042 by a distance M. This will return the tool 1042 currently on the spindle to the fixture 1043 of the first tool 1042, completing the tool return operation.

[0032] After the tool return operation is completed, the first spindle SP1 or the second spindle SP2 is moved to the tool change reference point E, and then the first spindle SP1 or the second spindle SP2 is moved downward along the Y axis by a distance L according to the tool number n of the tool 1042 to be replaced. , then the first spindle SP1 or the second spindle SP2 moves a distance M along the Z-axis toward tool 1042. Tool 1042 is clamped by the first spindle SP1 or the second spindle SP2, completing the tool change operation. For example, assuming tool 1042 to be replaced is tool 10425, the spindle is first moved to the tool change reference point E. Then, the spindle is moved downward along the Y-axis by a distance L (L = N + 4G). Then, the spindle is moved a distance M along the Z-axis toward tool 10425. Tool 1042 is clamped by the spindle, completing the tool change operation.

[0033] The tool management mechanism of this embodiment, in terms of program implementation, simply establishes a tool change reference point based on the first tool 1042. Then, based on this reference point, a corresponding overlay is performed to achieve fixed-point, precision tool changes without tool rotation. Program control is simple, reliable, and fast, resulting in smooth, reliable, and fast tool changes. The linear tool magazine 104 of this embodiment perfectly solves the problem of simultaneously replacing the same model of tool 1042 in the same magazine 104 on two horizontal machining centers.
