[0021] In the above structure, during the operation of the machine tool, the user can fix the workpiece body 12 by moving the main shaft synchronous motor 5, the hydraulic support 25 and the mounting seat 7, so as to ensure the stability of the workpiece body 12 during the machining process. Cooperating with the operation of the first motor 6 and the third motor 13, the tailstock body 15 and the column 19 are moved, so that the tool on the milling cutter headstock 33 can machine the workpiece body 12. The positioning component 26 is used to accurately position the position of the milling cutter headstock 33, thereby improving the machining accuracy of the machine tool for the workpiece body 12. The characteristic that the position of the milling cutter headstock 33 can be flexibly changed can ensure that the machine tool can machine multiple parts of a single shaft workpiece, thereby increasing the operation range of the machine tool, reducing the application of equipment, and further improving the practicability of the machine tool. The second slide 37 and the third slide 39 can be separated and moved, or can be connected to form a whole and move on the top of the first linear slide rail 2.

[0022] In a preferred embodiment: the number of the positioning components 26 and the first slide 27 is several. The several positioning components 26 and the first slide 27 are divided into eight groups, and every two positioning components 26 and the first slide 27 are respectively connected to the bottom of the mounting seat 7, the tailstock bed saddle 32, the milling cutter headstock 33, the tailstock body 15, the first slide plate 34, the steady rest 11, the second slide plate 35, and the connecting plate 30 near both sides.

At the same time, the positioning of the positioning component 26 can ensure the machining accuracy of the machine tool for the workpiece body 12.

[0024] In a preferred embodiment: the outer wall of the steady rest 11 is closely attached to the outer wall of the workpiece body 12, and the workpiece body 12 is fixedly connected to the output shaft of the main shaft synchronous motor 5 through the steady rest 11.

[0025] In the above structure, through the structure of the steady rest 11 provided, during the use of the machine tool, the user can position and clamp the workpiece body 12 of different sizes by moving the steady rest 11, so as to avoid the situation of position deviation of the workpiece body 12 during the machining process, thereby ensuring that the machine tool can accurately machine the workpiece body 12.

[0027] In the above structure, the 304 stainless steel material has the characteristics of hardness and wear resistance, which can effectively reduce the wear degree of the first slide block 27 during movement, thus extending the service life of the first slide block 27. At the same time, the 304 stainless steel material also has the characteristic of low cost, thereby reducing the production and application costs of the machine tool.

[0028] In a preferred embodiment: the tailstock body 15 moves along the X and Y axes respectively through the third motor 13 and the fourth motor 14, and the bottom of the tailstock body 15 is slidably connected to the top of the fourth linear slide rail 23.

[0030] In a preferred embodiment: the middle part of the tool holder 17 is rotatably connected to the outer wall of the tailstock body 15, and one end of the tool holder 17 far from the fifth motor 18 corresponds to the position of the outlet of the power tailstock tool magazine 16.

[0031] In the above structure, through the structures of the tool holder 17 and the fifth motor 18, the center rest 11 and the hydraulic support 25 are used to position the workpiece body 12, so that the column 19 can directly perform processing operations on the workpiece body 12 by adjusting the height after moving, thus facilitating the user to perform processing operations on workpieces of different sizes and further improving the application range of the machine tool.

[0032] In a preferred embodiment: the bottom of the mounting seat 7 is slidably connected to the top of the second linear slide rail 3, and the top of the first linear slide rail 2 is slidably connected to the bottom of the tailstock saddle 32. There is a 5 cm gap between the bottom of the tailstock saddle 32 and the top of the mounting seat 7.

[0033] In the above structure, the distance between the tailstock saddle 32 and the mounting seat 7 can ensure that the milling cutter spindle box 33 can move to perform processing operations on different depth holes of the workpiece body 12, thus ensuring the processing effect of the machine tool on the workpiece body 12. At the same time, the seventh motor 24 is used to move the turret 9 to perform cutting or grinding operations on the surface of the workpiece body 12, thereby realizing the effect of performing various processing techniques on a single workpiece body 12.

[0035] In the above structure, through the provided linear slide rail four 23 structure, the tailstock body 15 is moved under the influence of the operation of the motor four 14, so that the power tailstock tool magazine 16 can perform tool replacement operations on the tailstock body 15, thereby achieving the effect of automatically replacing tools for different machining processes, and further improving the automation of the machine tool and the machining efficiency of the user for the workpiece body 12.

[0036] In a preferred embodiment: the column 19 moves in the Y-axis direction along the outer wall of the carriage three 39 through the motor nine 36, and the column 19 moves in the X-axis direction along the outer wall of the linear slide rail one 2 through the motor one 6.

[0037] In the above structure, through the provided column 19 and tailstock saddle 32 structure, the column 19 can move along the outer wall of the tailstock saddle 32, so that the column 19 can perform machining operations on different positions of the workpiece body 12, thereby increasing the machining range of the machine tool, and there is no need to use multiple sets of equipment for machining operations at different positions, and further ensuring the machining effect and efficiency of the machine tool for the workpiece body 12.

[0038] In a preferred embodiment: the positioning component 26 is composed of a time grating linear encoder and a brake. The number of the power tailstock tool magazine 16, the tool holder 17 and the motor five 18 is two, and the other power tailstock tool magazine 16, the tool holder 17 and the motor five 18 are all arranged on the outer wall of the column 19.

[0039] In the above structure, through the provided time grating linear encoder and brake structure, the tailstock body 15 can be automatically locked after being positioned at an accurate position, so as to ensure that the tool on the tailstock body 15 can accurately fit the outer wall of the workpiece body 12 for machining operations, and further ensuring the machining accuracy of the machine tool for the workpiece body 12.

[0040] Working principle: First, after the user assembles the machine tool, the workpiece body 12 can be fixed by moving the main shaft synchronous motor 5 and the mounting base 7. Subsequently, by moving the mounting base 7, the turret 9 can be brought closer to one end of the workpiece body 12 away from the bed 1, so that the cutting tool on the turret 9 can perform machining operations on the workpiece body 12. After the drilling or grinding operation is completed, the user can rotate the first cutter head 10 to replace the cutting tool on the turret 9. After machining the workpiece body 12 one by one through the above same steps, the effect of performing multiple process machining on the workpiece body 12 is achieved. Then, by moving the column 19, milling operations can be performed on the workpiece body 12, thereby reducing the number of equipment used by the user, reducing the space occupancy rate of the machine tool, improving the practicality of the machine tool. At the same time, in cooperation with the positioning of the positioning component 26 and the replacement of the tools on the tailstock body 15 and the column 19, the effect of automatically measuring the workpiece body 12 is achieved, thereby ensuring the precise machining of the workpiece body 12 by the machine tool, and also facilitating the user to measure the workpiece body 12, avoiding errors caused by multiple clamping of the workpiece, and thus improving the machining accuracy of the user for the workpiece body 12.
