[0002] Large gantry machine tools are the main equipment used in the field of metal cutting. Machine tools can be divided into several categories based on their use and functions, such as lathes, milling machines, grinders, etc. Lathes and machining center machine tools have the largest market share. However, with the development of marketization, it is increasingly difficult for a single machine tool function to meet customer needs.

[0003] Especially for many small and medium-sized processors, in response to the processing needs of different orders, they need equipment that can continue to meet the needs of various parts and processing methods. Although many compound function machine tools on the market can achieve the functions of turning and milling at the same time, such machine tools are often targeted at a single industry and cutting products, and it is difficult to meet the needs of customers for production changes. For this reason, we provide a turning and milling compound workbench structure. Utility Model Content

DETAILED DESCRIPTION

[0024] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the specific implementation method, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.

[0025] Embodiment 1

[0026] See also Figure 1-3 As shown, a lathe-milling composite workbench structure comprises a milling workbench 2 and a lathe workbench 1, wherein the lathe workbench 1 is arranged in the middle of the milling workbench 2 and the two are independent of each other, and the bottoms of the lathe workbench 1 and the milling workbench 2 are both threadedly connected with a foot assembly 4 and the tabletops of the two workbenches are leveled by the foot assembly 4;

[0027] The anchor assembly 4 includes an adjustment bolt 402 threadedly connected to the bottom of the workbench and locked with a locking nut 401 after the height is leveled. A anchor pad 403 is fixed to the bottom of the adjustment bolt 402, and the anchor pad 403 is fixed to the ground.

[0028] A lathe workbench base 5 is provided at the bottom of the lathe workbench 1, and the lathe workbench 1 can rotate relative to the lathe workbench base;

[0029] Furthermore, since the working surfaces of the two workbenches are flush and T-slots are provided on both workbenches, a rigid connecting key 3 is provided at the connection between the T-slots on the turning workbench 1 and the milling workbench 2, so as to connect the two workbenches together to form a rigid whole; after releasing the connection state of the connecting key 3, the turning workbench 1 can be used to rotate alone for turning processing, and when the connecting key 3 is in the connected state, the two workbenches become a whole to perform milling operations of large parts.

[0030] Embodiment 2

[0031] like Figure 4-Figure 5 As shown, in the first embodiment, the use, installation and removal of the connecting key 3 are relatively troublesome. A circular installation space is opened in the T-slot of the lathe workbench 1 or the milling workbench 2. A rotating disk 6 is rotatably connected in the installation space. An eccentric groove 601 is opened at the bottom of the rotating disk 6. A bushing 7 is slidably installed in the eccentric groove 601. A pin is rotatably sleeved in the bushing 7. An extension rod 8 is rotatably connected to one end of the pin. The connecting key 3 is fixed to the end of the extension rod 8 away from the bushing 7. The movement trajectory of the connecting key 3 is still along the direction of the T-slot.

[0032] A mounting seat 9 is fixedly installed at the top center of the rotating disk 6, a locking pin 10 is slidably installed in the mounting seat 9 by a spline connection, a floating seat 12 is floatingly installed on the top of the mounting seat 9, a plurality of springs 13 are evenly arranged between the floating seat 12 and the top of the mounting seat 9, each spring 13 is respectively in contact with the mounting seat 9 and the floating seat 12, and a guide pin 14 is also arranged on the top of the mounting seat 9, the guide pin 14 cooperates with the guide hole provided on the floating seat 12 to guide the lifting and lowering of the floating seat 12;

[0033] An extrusion sleeve 15 is provided on the outer peripheral fixed sleeve of the middle section of the locking pin 10, and a locking plate 11 is fixed on the T-slot near the working surface. In the natural state, splines are provided at the height positions of the locking pin 10 and the locking plate 11, and the rotational freedom of the locking pin 10 is restricted by cooperating with the locking plate 11; a hexagonal wrench operating hole is provided on the top of the locking pin 10.

[0034] When the utility model is in use, when it is necessary to release or restore the connection state of the connecting key 3, a hexagonal wrench is inserted into the hexagonal wrench operating hole, and pressure is applied downward to release the matching relationship between the locking pin 10 and the locking plate 11. The locking pin 10 is rotated to drive the rotating disk 6 to rotate through the mounting seat 9, and the connecting key 3 at the end of the extension rod 8 is translated to a certain position in the T-slot under the action of the eccentric groove 601; when the position is reached, the pressure on the locking pin 10 is cancelled, and under the action of the spring 10, the locking pin 10 moves upward until the locking pin 10 is matched with the locking plate 11, and the rotational freedom is restricted again, thereby quickly completing the deployment and positioning of the connecting key 3.

[0035] The above description is only a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Although the present invention has been disclosed as a preferred embodiment as above, it is not intended to limit the present invention.
