With the continuous development of science and technology and changes in market demand, various types of composite special-purpose machine tools have emerged, such as turning and milling, boring and milling machines and other special-purpose machine tools. These composite special-purpose machine tools have improved processing efficiency and reduced labor and time costs, but they are still far from meeting market needs.

[0003] The turning and milling machines currently on the market cannot directly complete the boring function. One method is to modify the boring bar on the tailstock for boring, and the other method is to install a set of special boring devices on the slide. Both methods are relatively troublesome.

Instead, they are used to distinguish the cross-sectional views of the components in the drawings.

[0014] See also Figure 1-9The integrated turning, milling and boring compound machine tool comprises a bed 1, a spindle box 2 fixedly mounted on the bed 1, a center frame 3 slidably connected to the bed 1, a slide 4 and a tailstock 5, and a reduction box 6 fixedly mounted at the bottom of the slide 4. The center frame 3 can be used to limit and support one end of the part so as to clamp the part between the spindle box 2 and the tailstock 5. A slide plate 7 is slidably connected to the outer side of the top of the slide 4. The inner thread of the slide 7 is sleeved with a first screw rod 8 rotatably connected to the inside of the slide 4. The rotation of the first screw rod 8 can drive the mounting plate 12 to move so as to adjust the radial feed amount of the turning and milling station and the boring station of the compound machine tool. A support frame 9 is fixedly mounted on the top of the slide 7. A turntable 10 is rotatably connected to the inner top of the support frame 9, and a station switching mechanism 11 is fixedly mounted on the outer side of the support frame 9. A mounting plate 12 is fixedly mounted on the outer side of the top of the turntable 10. The power tool turret 13 and the first support block 14 are slidably connected with the second support block 15. The power tool turret 13 can be installed with multiple different types of tools at the same time, and it has a milling function. The tool position can be changed during the processing of the parts, and the parts can be drilled, milled and tapped. The first support block 14 and the second support block 15 are both rotatably connected with a pressure block 16 through a fixed pin. The inner side of the pressure block 16 is rotatably connected with a bolt 17 that is clamped on the inner side of the first support block 14 and the second support block 15. The outer thread sleeve at the bottom end of the bolt 17 is equipped with a nut. Through the cooperation of the first support block 14, the second support block 15, the pressure block 16 and the bolt 17, a boring device for fixing the boring tool rod can be formed. An adjusting mechanism 18 that is transmission-connected to the second support block 15 is fixedly installed on the inner side of the mounting plate 12. The outer sides of the first support block 14 and the second support block 15 are both provided with a rebound mechanism 19 fixedly installed on the pressure block 16.

[0015] The station switching mechanism 11 includes a first support 111 and a second support 112 fixedly mounted on the inner side of the support frame 9, a servo motor 113 fixedly mounted on the outer side of one side of the support frame 9, and a worm gear 114 fixedly sleeved on the turntable 10 and extending out of the outer side of the bottom end of the outer side of the support frame 9. A worm 115 meshing with the outer edge of the worm gear 114 is rotatably connected between the first support 111 and the second support 112. The outer side of one end of the worm gear 115 extending out of the outer side of the second support 112 is fixedly sleeved with the outer side of one end of the servo motor 113 extending to the inner side of the support frame 9 through a shaft sleeve 116. The drive can drive the worm 115 to rotate and drive the mounting plate 12 installed on the turntable 10 to rotate 180 degrees around the axial direction of the turntable 10 through the worm gear 114, thereby switching the positions of the power turret 13 and the boring station. In the process of processing parts, there is no need to repeatedly disassemble and assemble the boring device, and the meshing transmission between the worm gear 114 and the worm 115 allows the turntable 10 to self-lock after rotating to the set angle, ensuring that the power turret 13, the first support block 14 and the second support block 15 will not shake during the process of processing parts on the compound machine tool.

[0016] Among them, the adjusting mechanism 18 includes a second screw rod 181 threadedly sleeved inside the second supporting block 15, one end of the second screw rod 181 extending outside the second supporting block 15 is movably sleeved on the outer side with a first fixing plate 182 fixedly installed on the mounting plate 12, and the other end of the second screw rod 181 extending outside the second supporting block 15 is movably sleeved on the outer side with a second fixing plate 183 fixedly installed on the inner side of the top of the mounting plate 12, an annular boss 184 located between the second supporting block 15 and the first fixing plate 182 is provided on the outer side of one end of the second screw rod 181, and a rotating disk 185 is fixedly sleeved on the outer side of one end of the second screw rod 181 extending outside the first fixing plate 182, and the second screw rod 181 can be limitedly supported by the annular boss 184 through the cooperation of the first fixing plate 182 and the second fixing plate 183, ensuring that the second screw rod 181 can stably rotate around its own axial direction, and facilitating the assembly of the adjusting mechanism 18 while opening a threaded hole matching the second screw rod 181 inside the second supporting block 15.

[0017] Among them, the rebound mechanism 19 includes a first mounting block 191 fixedly mounted on the outside of the first support block 14 and the second support block 15, and a second mounting block 192 fixedly mounted on the outside of the pressure block 16. The first mounting block 191 and the second mounting block 192 are respectively fixedly mounted with a first fixing rod 193 and a second fixing rod 194 inside, and the outer sides of both ends of the first fixing rod 193 and the second fixing rod 194 are jointly mounted with a tension spring 195. After loosening the nut on the bolt 17, the pressure block 16 can be driven to rotate around the axial direction of the fixing pin under the elastic force of the tension spring 195, thereby gradually releasing the limit on the boring bar inside the first support block 14 and the second support block 15. In this process, there is no need to manually open the pressure block 16, and the boring bar can be directly pushed manually, so as to facilitate the installation and position adjustment of the boring bar.

[0018] After the parts are clamped on the compound machine tool, the bolt 17 is loosened to drive the pressure block 16 to gradually open under the elastic force of the tension spring 195, and the boring bar is inserted into the inner side of the first support block 14 and the second support block 15. After the position is adjusted, the bolt 17 is rotated and tightened in the opposite direction. The boring bar is pressed and fixed by the cooperation between the first support block 14, the second support block 15 and the pressure block 16, and the outer circle of the part is turned by the tool on the power turret 13. The part can be drilled, milled and tapped by switching the tool on the power turret 13. After the above processes are completed, start The servo motor 113 is driven to rotate the worm 115 through the drive of the servo motor 113. At the same time, the meshing transmission between the worm wheel 114 and the worm 115 drives the mounting plate 12 to rotate 180 degrees around the axial direction of the turntable 10. In this process, the positions of the power turret 13 and the boring device can be switched, and the boring bar can be switched to the boring station. At this time, the inner hole of the part is bored by the tool on the boring bar. The last clamping completes the turning, milling and boring process of the cylinder part.
