[0002] The double-spindle double-turret machine tool is a general-purpose metal cutting machine tool. It is equipped with two spindles and can perform machining at both ends simultaneously. It is suitable for double-sided simultaneous turning of short shaft parts. It is designed to ensure coaxiality and is specialized in machining shaft products. It is an ideal processing equipment for short shaft products with high coaxiality requirements.

[0003] Chinese Patent with the application number CN202110489875.2 discloses a double-spindle double-turret machine tool. By using a fixed turret and a movable turret and rotating the fixed turret and the movable turret, the tool can be automatically switched, which facilitates the flexible use of the tool during the machining process of the machine tool, brings convenience to the machining operation of the machine tool, and improves the convenience of use. By setting a fixed spindle, a movable spindle, a fixed turret and a movable turret on this machine tool, the machine tool is equipped with a double spindle and a double turret. Therefore, the machine tool can perform machine tool compound machining on two parts simultaneously, thereby improving the machining speed of the parts by this machine tool and improving the use efficiency of this machine tool. By sliding the second slider on the second slide rail, the second moving plate moves more stably and smoothly. By sliding the third slider on the third slide rail, the third moving plate moves more stably and smoothly back and forth. By making the second moving plate and the third moving plate move more smoothly, the accuracy of controlling the cutting force and cutting depth during the machining process of this machine tool is improved, and further the precision of machining parts by this machine tool is improved, and the use accuracy of this machine tool is improved.

[0004] However, in essence, it still has two spindles corresponding to two turrets, machining two parts simultaneously, and its tool change is still manually operated. Although multiple tools can be installed on its two turrets, when machining high-precision parts, corresponding tools often need to be replaced for machining at different positions, and the overall number of tools is limited. Therefore, the way of manual intervention and manual tool change is required, and the tool change speed is slow, which is not suitable for high-efficiency automated production lines and black light factory machining.

[0035] In the present utility model, the surfaces of the workbench 4 on both sides of the main shaft 2 are inclined, ensuring that during the cutting process, metal chips can be uniformly collected through the inclined surface of the workbench 4 and discharged from the rear end.

[0036] In the present utility model, both the left tool disc 11 and the right tool disc 18 are in a polygonal structure, and tool mounting taper holes are arranged on each surface of the outer sides of the polygonal left tool disc 11 and right tool disc 18.

[0037] Embodiment: During use, first, the workpiece to be processed is installed on the top of the main shaft 2 through the jaw 3. The rotation of the main shaft 2 drives the jaw 3, and then drives the workpiece to rotate. At this time, under the action of the left adjustment component and the right adjustment component, the left turret housing 10 and the right turret housing 17 move up, down, left, and right simultaneously. The cutting tools 24 on the left cutting tool disk 11 and the right cutting tool disk 18 respectively arranged at one ends of the left turret housing 10 and the right turret housing 17 close to the jaw 3 are used to perform cutting processing on the workpiece.

[0038] When the left adjustment component and the right adjustment component adjust the positions of the left turret housing 10 and the right turret housing 17, the longitudinal drive motor cooperates with the first longitudinal transmission screw 8 and the second longitudinal transmission screw 15 to drive the left slider 7 and the right slider 14 to move up and down along the first longitudinal guide rail 6 and the second longitudinal guide rail 13. At the same time, the transverse drive motor cooperates with the first transverse transmission screw and the second transverse transmission screw to drive the left turret housing 10 and the right turret housing 17 to move left and right along the first transverse guide rail 9 and the second transverse guide rail 16 inside the left slider 7 and the right slider 14, thereby changing the cutting positions of the left cutting tool disk 11 and the right cutting tool disk 18 respectively arranged at one ends of the left turret housing 10 and the right turret housing 17 close to the jaw 3.

[0039] When the cutting tool 24 needs to be replaced, first, a new cutting tool 24 is clamped on the tool holder 23 of the tool magazine 21 through one of the clamping grooves of the tool clamp 31. The tool changing robot 20 adjusts the first rotating rod 27 to horizontally rotate along the axis of the fixed seat 25 through the first adjusting motor 26. After rotating to an appropriate position, the inclination angles of the first rotating rod 27 and the second rotating rod 29 are adjusted through the second adjusting motors 28 at both ends of the first rotating rod 27. After rotating to an appropriate position, the cutting tool 24 that needs to be replaced on the left cutting tool disk 11 or the right cutting tool disk 18 is pulled out through the clamping groove of the tool clamp 31 that does not clamp the new cutting tool 24. Then, the third adjusting motor 30 drives the tool clamp 31 to rotate the other clamping groove of the tool clamp 31 that clamps the new cutting tool 24 to the corresponding position of the tool installation taper hole on the left cutting tool disk 11 or the right cutting tool disk 18 where the cutting tool 24 needs to be replaced, and the new cutting tool 24 is inserted into the tool installation taper hole. The tool changing robot 20 repeats the above actions, and places the replaced cutting tool 24 in the idle tool placement hole on the surface of the tool holder 23.

[0040] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims are included in the present invention, and any figure mark in the claims should not be regarded as limiting the claims involved.

[0041] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
