[0029] The following disclosure provides many different implementation methods or examples for different solutions to implement this utility model.

[0030] See attached document Figure 1 To be continued Figure 6 As shown, a modular machine tool structure includes a machine tool body 1, a machining spindle 2 mounted on the machine tool body 1, a tailstock device 3, a tool head device 4, and a quick-release replacement device 5, all mounted on one end of the machining spindle 2.

[0031] In one embodiment of this utility model, the machine tool body 1 includes an inclined bed 11 and a cutter head device 4 disposed on the upper end face of the bed 11, which can reciprocate along the Z-axis and E-axis respectively. The X-axis of this machine tool adopts a C1-grade ball screw, and the Z-axis and E-axis both adopt C2-grade ball screws, and the diameter of each is 40mm.

[0032] In one embodiment of this utility model, the angle between the E-axis and the X-axis is 30°, that is, the bed 11 adopts a 30° integral slant bed, and the bed 11 is cast from HT300 material components to ensure the rigidity of the hard turning. Not only is the cross-sectional area larger than that of a flat bed of the same specification, meaning it has stronger bending and torsional resistance, but the cutting force is also basically in the same direction as the gravity of the workpiece. Therefore, the machining spindle 2 runs relatively smoothly, is not prone to cutting vibration, and facilitates chip removal during machining.

[0033] In one embodiment of the present invention, the bed 11 is further provided with a first drive assembly for driving the cutter head device 4 to perform Z-axis reciprocating motion. The first drive assembly includes a first drive motor 61 arranged laterally and a first ball screw 62 arranged at the output end of the first drive motor 61. The other end of the first ball screw 62 is provided with a slide plate 63 for mounting the cutter head device 4.

[0034] In one embodiment of this utility model, the slide plate 63 is arranged along the E-axis direction, and the lower end surface of the slide plate 63 is provided with two first slide grooves spaced apart. Along the length direction of the bed 11, two first slide rails corresponding to the first slide grooves are provided at intervals. The first slide rails adopt 45 roller heavy-duty linear guides, and both the X-axis and Z-axis adopt 10nm grating rulers. Full closed-loop control is used to ensure the stability of continuous processing.

[0035] In one embodiment of this utility model, the tool disc device 4 includes a tool magazine 41 disposed on a slide plate 63 and a tool disc 42 disposed on one side of the tool magazine 41. The tool disc 42 is provided with a plurality of tool mounting positions spaced apart, and twelve tool mounting positions are provided at intervals on the tool disc 42, all of which are controlled by servo motors, including a 25mm square tool and a 40mm boring tool.

[0036] In one embodiment of the present invention, a second drive assembly for driving the reciprocating motion of the E-axis of the tool magazine 41 is provided between the tool magazine 41 and the slide plate 63. The second drive assembly includes two second slide rails 71 arranged along the E-axis on the upper end surface of the slide plate 63 and two second slide grooves corresponding to the second slide rails 71 arranged at intervals on the lower end surface of the tool magazine 41. The second slide rails 71 are 45 roller heavy-duty linear guides.

[0037] In one embodiment of this utility model, the tailstock device 3 includes a mounting plate 31 slidably connected to the bed 11, a center assembly, and a base 33 for mounting the center assembly. An inclined platform 34 is provided between the base 33 and the mounting plate 31. Unlike the previous fully manual tailstock which uses manual pushing or tool post dragging to move the tailstock body along the bed and thus approach or move away from the workpiece, this modular machine tool can drive the upper center assembly to reciprocate through the guide rail assembly between the mounting plate 31 and the bed 11, and can precisely control the torque to further improve the machining accuracy.

[0038] In one embodiment of this utility model, the tip assembly includes a push rod 321 that can be inserted into the base 33 and a sleeve 322 sleeved on the push rod 321. The diameter of the push rod 321 gradually decreases from the feeding direction to the other end, which can facilitate quick installation.

[0039] In one embodiment of this utility model, the top of the base 33 is provided with a mounting cavity into which the push rod 321 can be inserted. The mounting cavity is arranged along the length direction of the base 33 and is offset from the lower end face of the base 33 to ensure that it is aligned with the machining spindle on the opposite side.

[0040] In one embodiment of this utility model, a quick-release replacement device 5 is disposed between the inclined platform 34 and the base 33. The quick-release replacement device 5 includes a rectangular protrusion 51 disposed on the upper end surface of the inclined platform 34 that can be engaged with the lower end surface of the base 33, and a fixing plate 52 disposed at one end of the rectangular protrusion 51 for connecting the inclined platform 34 and the base 33. Two threaded holes corresponding to the inclined platform 34 and the base 33 are respectively disposed on the upper and lower sides of the fixing plate 52 to ensure the stability after the inclined platform 34 and the base 33 are fastened together.

[0041] In one embodiment of this utility model, a quick-release component 341 is provided on the inclined platform 34. The upper end surface of the quick-release component 341 is provided with a plurality of cylindrical protrusions that can be used for mounting components, thereby realizing a modular design that can be applied to servo tailstocks and sub-spindle structures of different specifications.

[0042] In one embodiment of this utility model, a protective plate is provided laterally on the side of the mounting plate 31. The protective plate is set perpendicular to the mounting plate 31, and the height of the protective plate is greater than the thickness of the mounting plate 31, so as to effectively protect the connection between the mounting plate 31 and the inclined platform 34.

[0043] In one embodiment of this utility model, a protective cover is provided on the machining spindle 2 to further ensure the service life of the machining spindle 2. A high-power second drive motor 8 is provided at one end of the machining spindle 2 away from the tailstock device 3 to further improve the maximum speed and cutting torque. A clamping device 9 is provided at the other end of the machining spindle 2, and the clamping device 9 is preferably a three-jaw chuck.

[0044] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
