Description

Technical Field

[0001] The utility model relates to the technical field of lathes, in particular to a double-sided butt-jointed tool lathe. Background Art

[0002] Turning is a cutting method that uses the combined motion of the rotation of the turning tool and the rotation of the workpiece to achieve cutting processing on the workpiece, so that the workpiece meets the requirements of use in terms of shape accuracy, position accuracy, and machined surface integrity.

[0003] For example, a Chinese patent with announcement number CN218130400U discloses a horizontal inclined rail tool arrangement CNC lathe, which includes a machine body, an X-axis inclined rail assembly, a Y-axis inclined rail assembly, and a spindle box. The spindle box and the X-axis inclined rail assembly are arranged on the machine body at intervals. The Y-axis inclined rail assembly is slidably connected to the X-axis inclined rail assembly. The X-axis inclined rail assembly can drive the Y-axis inclined rail assembly to move in translation. A tool holder is arranged on the Y-axis inclined rail assembly. The spindle box is located on one side of the Y-axis inclined rail assembly. A chuck for clamping a workpiece is arranged on the spindle box. A chip removal port is also arranged on the machine body. The Y-axis inclined rail assembly is used to drive the tool holder to move in translation, and the X-axis inclined rail assembly is used to drive the Y-axis inclined rail assembly and the tool holder to approach and move away from the spindle box.

[0004] The above technical solution has the following defects: the above lathe clamps the workpiece through the chuck and drives the workpiece to rotate, and then uses the tool on the tool holder to turn the inner and outer cylindrical surfaces, inner and outer conical surfaces, inner and outer curved surfaces, threads, etc. of the shaft workpiece or disk workpiece, or to slot, drill, expand, reamer, bore, etc. However, this lathe needs to clamp one end of the shaft workpiece, so the tool can only process the other end of the workpiece at a time. For parts that need to be processed at both ends, the workpiece can only be clamped first and then one end of the workpiece can be processed. After the processing is completed, the workpiece must be removed from the chuck and then the workpiece is clamped at another end before the tool can process the other end of the workpiece. In other words, the workpiece needs to be clamped and processed twice to complete the processing of both ends of the workpiece; and when the workpiece is replaced, the clamping depth of the workpiece needs to be manually adjusted, resulting in a slow clamping speed of the workpiece and poor consistency of the product after the workpiece is processed, thereby affecting the processing efficiency of the above machine tool, and is not suitable for workpieces processed in large quantities.

[0032] Working process: During the use of the lathe, the external power supply is energized. When one end of the workpiece needs to be fixed, the workpiece is placed on the right side of the second chuck 11, and the electric telescopic rod 13 is started. One end of the electric telescopic rod 13 moves inside the hydraulic oil storage tank 12. The hydraulic oil storage tank 12 pushes the column push block 14 to move. The column push block 14 moves inside the hydraulic oil storage tank 12. The sealing ring 15 fixed on the outside of the column push block 14 has the effect of sealing between the second chuck 11 and the column push block 14. When the hydraulic oil storage tank 12 moves, the hydraulic oil in the hydraulic oil storage tank 12 enters the oil port 18 from the oil passage 17, and then enters the oil push shell 16 from the oil port 18. At this time, the hydraulic oil in the oil push shell 16 increases, and the hydraulic oil pushes the solid push rod 20 to move. The silicone ring 21 fixedly connected to the outside of the solid push rod 20 has the effect of sealing between the solid push rod 20 and the oil push shell 16. The limit baffle 19 has the effect of limiting the movement of the solid push rod 20. The movement of the solid push rod 20 drives the push torque plate 22 to move, and the push rod 20 moves. The square slide bar 23 fixed on the outer side of the moment plate 22 has the effect of limiting the movement of the push moment plate 22. The movement of the push moment plate 22 drives the clamping plate 24 to move, and the clamping plate 24 clamps the workpiece. The clamping plate 24 is fixed to the push moment plate 22 by the fixing bolt 25, which is convenient for maintenance of the clamping plate 24. At this time, the workpiece fixation can be completed, and the second servo motor 9 is started to push the double-row tool 10 to move. The rear end of the double-row tool 10 moves to the front end of the tool holder 8, and the double-row tool 10 processes the workpiece. After the processing is completed, the first servo motor 3 is started to drive the threaded rod 4 to rotate, and the threaded rod 4 drives the screw plate 5 to move, and the screw plate 5 drives the chuck frame 6 and the first chuck 7 to move. When the other end of the workpiece contacts the first chuck 7, the electric telescopic rod 13 is started to shrink. At this time, the hydraulic oil inside the oil push shell 16 enters the hydraulic oil storage tank 12, thereby resetting the clamping plate 24. According to the above principle, the electric telescopic rod 13 inside the first chuck 7 is started to fix the workpiece again, thereby processing the other end of the workpiece.
