[0020] The present utility model will be further described in detail below in conjunction with the drawings of the specification;
[0021] As Figures 1 to 6As shown in the figure, a multi-functional tool includes a tool holder 1, a first turning tool 31 and a second turning tool 41 respectively fixed on both sides of the tool holder 1, a taper sleeve 5 fixedly connected to the tool holder 1, and a center drill bit 51 fixed on the taper sleeve 5; the tool holder 1 includes a mounting plate 2 and a first mounting block 3 and a second mounting block 4 welded to both ends of the mounting plate 2. Reinforcing blocks are welded and fixed between the mounting plate 2 and the first mounting block 3 and between the mounting plate 2 and the second mounting block 4, strengthening the connection strength between the mounting plate 2 and the middle of the first mounting block 3 and the second mounting block 4 respectively, and improving safety; a first mounting hole 22 for the front end of the taper sleeve 5 to pass through and a mounting groove 21 matching the taper sleeve 5 are provided in the center of the mounting plate 2. A first screw hole 23 is arranged around the first mounting hole 22 in a circumferentially evenly distributed manner. The first mounting hole 22 and the first screw hole 23 are arranged in the mounting groove 21. A fixing hole 53 corresponding to the first screw hole 23 is provided on the taper sleeve 5. The taper sleeve 5 is fixedly connected to the mounting plate 2 through a screw. An elastic chuck 52 fixedly connected to the taper sleeve 5 is provided at the front end of the taper sleeve 5. The elastic chuck 52 is fixedly connected to the center drill bit 51, making the center drill bit 51 clamped more stably. A second mounting hole 32 and a second screw hole communicating with the second mounting hole 32 are provided on the first mounting block 3. The second mounting hole 32 is matched with the first turning tool 31. After the first turning tool 31 is inserted into the second mounting hole 32, it is fixed in the second mounting hole 32 through a screw. Two second screw holes are provided on the first mounting block 3, making the first turning tool 31 fixed more firmly and avoiding safety accidents caused by the first turning tool 31 falling off during use. A third mounting hole 42 and a third screw hole communicating with the third mounting hole 42 are provided on the second mounting block 4. The third mounting hole 42 is matched with the second turning tool 41. After the second turning tool 41 is inserted into the third mounting hole 42, it is fixed in the third mounting hole 42 through a screw. Two third screw holes are provided on the second mounting block 4, making the second turning tool 41 fixed more firmly and avoiding safety accidents caused by the second turning tool 41 falling off during use. At the same time, the two processes of drilling the center hole and turning the outer circle are realized simultaneously, reducing the cost and the possibility of accidents.
[0022] As Figure 2 and Figure 3 shown, the first turning tool 31 and the second turning tool 41 are staggered with each other in the axial direction, and the first turning tool 31 and the second turning tool 41 are staggered with each other in the longitudinal direction. The turning tool that first contacts the workpiece 6 is the rough turning tool, and the turning tool that later contacts the workpiece 6 is the finish turning tool. The two processes of finish turning and rough turning can be carried out on the workpiece 6 simultaneously, reducing the processes and the cost.
[0023] Principle of use of the present utility model: First, the operator fixes the taper sleeve 5 and the center drill bit 51 to the tool rest 1, then installs the finish turning tool and the rough turning tool on the first mounting block 3 and the second mounting block 4 respectively, and adjusts the feed amount of the two turning tools by adjusting the tightness of the screw. After adjusting the two turning tools to the appropriate positions, the workpiece 6 slowly approaches the tool rest 1 and contacts the center drill bit 51 and the rough turning tool, and then contacts the finish turning tool, so that the center hole can be drilled and the workpiece 6 can be successively rough machined and finish machined, simplifying the machining process, reducing the working intensity of workers, and also reducing the time cost and labor cost.
