[0030] It should be noted that the milling machine generally includes machine tool accessories, which broadly refer to auxiliary devices for expanding the machining performance and use range of the machine tool, and have various types.

[0031] Please refer toFigure 1 , Figure 1 This is a schematic diagram of the radial tool holder 100 according to an embodiment of this application.

[0032] This application provides a radial tool holder 100 for milling turning, the radial tool holder 100 including a base 110, a sliding mechanism 120 and a mounting rod 130 for mounting a turning tool 170.

[0033] The base 110 is used to connect with machine tool accessories to provide a mounting base for the radial tool post 100 and to enable movement and rotation driven by the machine tool accessories.

[0034] A sliding mechanism 120 is provided on the side of the base 110 away from the machine tool accessory. The mounting rod 130 is connected to the sliding mechanism 120, and the mounting rod 130 extends in a direction parallel to the rotation axis of the machine tool accessory, and can move in a direction perpendicular to the rotation axis of the machine tool accessory under the drive of the sliding mechanism 120.

[0035] In this method, the base 110 and the mounting rod 130 cooperate to allow the mounting rod 130 to move circumferentially around its rotation axis by rotating the machine tool accessory. This, in turn, drives the cutting tool 170 mounted on the mounting rod 130 to move circumferentially. This achieves turning operations while converting the circumferential movement of the tool along the shaft part during machining from the horizontal movement of the machine tool accessory to the rotation of the machine tool accessory. This reduces the range of motion of the machine tool accessory, meaning that the machine tool accessory only needs to move vertically and rotate, thus improving machining efficiency.

[0036] Meanwhile, the sliding mechanism 120 adjusts the position of the mounting rod 130, which is the distance between the tool and the surface to be machined, ensuring machining accuracy and suitability for various machining operations, thus improving the versatility of the radial tool holder 100.

[0037] Furthermore, milling requires stopping the machine to change different tools depending on the work position, for example, for... Figure 3 The nozzle 2 shown is replaced with a milling cutter disc, a square shoulder milling cutter, a first bullnose milling cutter (for forward machining of the workpiece), and a second bullnose milling cutter (for inverted machining of the workpiece) at different positions, which further reduces machining efficiency. Furthermore, the use and maintenance of multiple different tools also increases costs. In contrast, this radial tool holder 100 enables milling and turning operations, typically eliminating the need to change multiple different tools; only a single type of turning tool is required. This effectively reduces machining costs, further improves machining efficiency without tool changes, and reduces tool maintenance difficulty.

[0038] In one embodiment, the base 110 extends along a direction perpendicular to the self-rotation axis of the machine tool accessory, and can provide a stable base for the installation and movement of the sliding mechanism 120 and the mounting rod 130. In addition, the base 110 is connected to the machine tool accessory with the self-rotation axis of the machine tool accessory as the center line, that is, the center of the base 110 and the connection between the base 110 and the machine tool accessory are located on the self-rotation axis of the machine tool accessory, which can further improve the stability of the radial tool rest 100 after being connected to the machine tool accessory.

[0039] In one embodiment, the sliding mechanism 120 includes a driving member 121 and a transmission assembly arranged and transmission-connected along the extension direction of the base 110, and the transmission assembly is provided with a sliding block 124, and the side of the sliding block 124 away from the base 110 is provided with the mounting rod 130. Preferably, the driving member 121 is a servo motor and a matching speed reducer.

[0040] In one embodiment, the transmission assembly is a lead screw transmission assembly, that is, the sliding mechanism 120 adopts lead screw transmission to realize the movement of the mounting rod 130, which can improve the positioning accuracy and stability of the movement of the mounting rod 130, and the lead screw transmission has strong load capacity, which can improve the stability of the tool.

[0041] In one embodiment, the base 110 is symmetrically provided at the bottom with a bearing seat 123, and the lead screw transmission assembly is connected with the bearing seat 123, thereby improving the transmission stability.

[0042] It can be understood that, in order to realize the stable movement of the sliding block 124 under the driving of the lead screw transmission assembly, the sliding block 124 is connected with the base 110 through a limiting structure 125.

[0043] In one embodiment, the base 110 is connected with the machine tool accessory through a connecting handle 150, and a conductive slip ring 160 is further arranged between the connecting handle 150 and the base 110, and the conductive slip ring 160 is connected with the sliding mechanism 120. It can be understood that the conductive slip ring 160 is further connected with a power supply and / or a controller, thereby providing power for the sliding mechanism 120 or controlling the sliding mechanism 120, and the wiring through the conductive slip ring 160 is convenient and does not hinder the rotation of the radial tool rest 100.

[0044] In one embodiment, the connecting handle 150 is a taper handle, and the small end of the connecting handle 150 is connected with the machine tool accessory, and the large end is connected with the base 110, which can improve the assembly convenience of the radial tool rest 100 and the machine tool accessory, especially when the machine tool accessory is the arm assembly 200, which is particularly convenient for connecting with the second arm 220. Preferably, the connecting handle 150 is a BT60 tool handle.

[0045] Please refer to Figure 2 , Figure 2 is a structural schematic view of the radial tool rest 100 of the embodiment of the present application assembled with the dust cover 140.

[0046] In one embodiment, a dust cover is provided on one side of the base 110 corresponding to the sliding mechanism 120 to improve the protection of the radial tool holder 100 and prolong its service life. Correspondingly, the dust cover is provided with a relief groove corresponding to the sliding path of the sliding mechanism 120 to allow the mounting rod 130 to move.

[0047] In one embodiment, the radial tool holder 100 further comprises an infrared temperature measurement probe provided on the base 110 or the sliding mechanism 120 or the mounting rod 130, which is directed towards the end of the mounting rod 130 to obtain the temperature of the cutting edge of the tool provided at the end of the mounting rod 130.

[0048] In one embodiment, the radial tool holder 100 further comprises a monitoring module provided on the base 110 or the sliding mechanism 120 or the mounting rod 130, which is used to monitor the distance between the cutting edge of the turning tool 170 mounted on the mounting rod 130 and the mounting rod 130, to determine the distance of the mounting rod 130 relative to the rotation axis of the machine tool accessory, and to monitor the tool wear condition, so as to ensure that the radial tool holder 100 can accurately and effectively process the surface to be processed.

[0049] Please refer to Figure 3 , Figure 3 is a schematic view of the use state of the embodiment of the present application and the machine tool arm assembly 200 after assembly.

[0050] In one embodiment, the machine tool accessory is an arm assembly 200, which comprises a first arm 210 and a second arm 220 in transmission connection with the end of the first arm 210. The first arm 210 can move in a direction parallel to the axis of the second arm 220, and the second arm 220 can rotate. The base 110 is detachably connected with the second arm 220, so as to realize the circumferential movement of the mounting rod 130 in the radial tool holder 100 and the turning tool 170 mounted thereon driven by the rotation of the second arm 220, and the axial movement of the mounting rod 130 along the axis of the shaft part driven by the first arm 210. Moreover, through the separate movement control of the first arm 210 and the second arm 220, the movement accuracy is higher, thereby improving the processing accuracy.

[0051] In other alternative embodiments, the machine tool accessory is a universal milling head, and the base 110 is detachably connected with the universal milling head.
