Description

Technical Field

[0001] This utility model relates to the field of machine tool parts processing technology, and more specifically, to a processing auxiliary tool fixed on a plate-type tool holder and a plate-type CNC lathe. Background Technology

[0002] With the development of lightweighting of torque transmission shafts in hydropower and wind power, most products have been redesigned as shaft forgings with holes in the middle. In the past, hole machining was mostly carried out using CNC milling and boring equipment, specifically through the machining method of CNC floor-type boring machines with helical feed. However, boring machine machining is inefficient, costly, and has a long machining cycle, and it is easy to damage the spindle after machining to a certain depth.

[0003] Another related technology involves machining using a single-tool-table horizontal lathe (single-tool-post horizontal lathe). However, single-tool-table horizontal lathes are prone to vibration during machining, which affects machining accuracy. Utility Model Content

[0044] like Figures 1 to 2 As shown, the machining auxiliary tool fixed on the plate tool holder according to an embodiment of this utility model includes:

[0045] Tool receiver 1, which is used to be mounted on the plate tool holder 7 of the plate CNC lathe;

[0046] A locking assembly is installed between the tool receiver 1 and the plate tool holder 7 to lock the tool receiver 1 relative to the plate tool holder 7.

[0047] Tool holder 2, which is connected to the tool receiver 1, and one end of the tool holder 2 is used to mount a tool for hole machining.

[0048] In this embodiment, in conjunction with the appendix Figure 1 As shown, when using this machining auxiliary tool fixed on the plate-type tool holder, first install the tool receiver 1 on the plate-type tool holder 7 of the plate-type CNC lathe. The plate-type tool holder 7 includes a main tool plate and a secondary tool plate. To improve the stability during machining, tool receivers 1 can be installed on the main tool plate and the secondary tool plate respectively. Then, a locking assembly is installed between the tool receiver 1 and the plate-type tool holder 7 to lock the tool receiver 1 relative to the plate-type tool holder 7, so that the tool receiver 1 is firmly fixed on the plate-type tool holder 7. Then, the tool bar 2 is connected to the two tool receivers 1 respectively. Then, the shaft forging is placed on the worktable of the plate-type CNC lathe.

Subsequently, the horizontal lathe is started, causing its spindle to rotate the shaft forging. Based on the material, dimensions, and hole requirements of the shaft forging, appropriate cutting parameters, such as rotational speed and feed rate, are set in the CNC system. The horizontal lathe is then operated to move the plate-type tool holder 7, equipped with this machining fixture, axially and radially (the tool at the front end of the tool holder 2, after being clamped, moves radially with the plate-type tool holder 7 and axially with the lathe bed). The tool on the tool holder 2 is moved to the starting position of the hole to be machined in the shaft forging. Machining begins, the CNC program is run, and the shaft forging rotates with the horizontal lathe spindle and is fed axially and radially under the drive of the plate-type tool holder 7, cutting the shaft forging and gradually forming the required hole. Once the hole reaches the predetermined dimensions and accuracy requirements, the tool feed is stopped, and the horizontal lathe spindle stops rotating. The machining auxiliary tool fixed on the plate tool holder of this utility model adopts a plate CNC lathe machining scheme, which has high machining efficiency and high precision compared with related technologies. It solves the machining bottleneck of milling and boring equipment and the problem of easy damage to machine tools, as well as the vibration problem of single tool holder lathe machining.

[0050] In this embodiment, in conjunction with the appendix Figure 1 and attached Figure 3 As shown, the tool receiver 1 includes a first block 11, a second block 12, and a connecting body 13. Both the first block 11 and the second block 12 can be rectangular block structures. The cross-sectional dimension of the connecting body 13 is smaller than that of the first block 11 and the second block 12. A portion of the connecting body 13 can be welded between the first block 11 and the second block 12, and the other portion of the connecting body 13 can be connected to the plate-type tool holder 7 via a locking assembly. A groove is formed between the first block 11 and the second block 12, and the tool shank can extend into the groove between the first block 11 and the second block 12. The first block 11 is located above the second block 12 (see attached diagram). Figure 1 (in the positive direction of the Z-axis), and the first block 11 has multiple bolt holes, and the corresponding position on the tool holder 2 also has threaded holes, so that the tool holder 2 can be fastened to the first block 11 by bolts.

[0051] Optionally, the connecting body 13 includes a first insertion part 131, and the plate-type tool holder 7 has a first mating notch 71 that matches the shape of the first insertion part 131. The first insertion part 131 is used to extend into the first mating notch 71. The locking assembly includes a first locking member 3, which is disposed between the first insertion part 131 and the first mating notch 71, and is used to lock the first insertion part 131 relative to the plate-type tool holder 7.

[0054] In this embodiment, in conjunction with the appendix Figure 6 To be continued Figure 8 As shown, the first locking member 3 includes a first wedge block 31 and a second wedge block 32. The two inclined surfaces of the first wedge block 31 and the second wedge block 32 can be joined together to form a rectangular block structure. Grooves can be opened on the inclined surfaces of the first wedge block 31 and the second wedge block 32, and a cylindrical structure is provided at each groove. The first bolt 33 passes through the cylindrical structure on the first wedge block 31. The inner wall of the cylindrical structure on the second wedge block 32 is threaded to serve as a first nut 34. The first bolt 33 can be threaded onto the first nut 34. By rotating the first bolt 33, the second wedge block 32 can be moved relative to the first wedge block 31, thereby adjusting the thickness of the first wedge block 31 and the second wedge block 3 after they are joined together, so as to facilitate pressing between the first insertion part 131 and the first mating notch 71.

[0055] In other embodiments, a locking pad may be installed between the first locking member 3 and the first insertion part 131. During the fixing process, the locking pad fits tightly with the first insertion part 131 and the first locking member 3, increasing the contact area between the first locking member 3 and the first insertion part 131, making the locking force distribution more uniform, and preventing excessive local stress from damaging the surface of the first insertion part 131. At the same time, the installation height and angle of the first insertion part 131 can be finely adjusted by replacing locking pads of different thicknesses to adapt to different processing requirements.

[0056] In other real-time configurations, the first locking element 3 may also include a tightening screw 35, which may pass through the second wedge block 32 and the first wedge block 31 in sequence and abut against the first bolt 33 to prevent the first bolt 33 from shifting.

The positioning pad 5 provides a precise positioning reference for the tool receiver 1, ensuring that the tool receiver 1 is installed accurately on the plate tool holder 7 and guaranteeing the positional accuracy of the machining hole. Through the cooperation of the positioning boss and the positioning slot, the displacement and rotation of the tool receiver 1 in the horizontal direction are restricted, enhancing the overall stability of the auxiliary fixture.

[0061] Optionally, the locking assembly further includes a wedge block 6, and the connecting body 13 has a pre-tightening inclined surface 133.
