Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of machining, and particularly relates to a U-drill tooling for lathe machining. Background Art
[0002] When drilling with a U-drill on a lathe, the tool rest of the lathe is not convenient for clamping the U-drill. Even some special tool rests for U-drills are used for clamping. However, under the large resistance of long-term drilling, it will cause serious wear of the machine tool and the tool rest is prone to damage. Content of the Utility Model
[0003] The technical problem to be solved by the utility model is to provide a U-drill tooling for lathe machining aiming at the deficiencies of the above-mentioned prior art. It is convenient for loading and unloading the U-drill, without adjustment, and at the same time, high-speed machining of the main shaft can be adopted.
[0004] The technical solution adopted by the utility model is: a U-drill tooling for lathe machining, including a bottom plate. A slider matching the sliding dovetail groove of the lathe is formed along the length direction at the bottom of the bottom plate. An angle iron bracket is fixedly installed on the bottom plate. A fixing plate is formed on the vertical side of the angle iron bracket. A fixing hole coaxially arranged with the chuck of the lathe is opened on the fixing plate, and several uniformly distributed flange mounting holes are opened around the fixing hole on the fixing plate. The tool holder flange is positioned and installed on both sides of the fixing plate through the flange mounting holes. A locking hole is opened at the top of the tool holder flange, and a locking bolt matching it is arranged in the locking hole.
[0005] Preferably, locking holes are opened at the top of the flange plates of the tool holder flanges on both sides of the fixing plate.
[0006] The beneficial effects of the utility model are as follows: The utility model is convenient for clamping U-drills with various clamping handle diameters, and the clamping operation is convenient without adjustment. At the same time, after clamping the U-drill, high-speed machining of the main shaft can be adopted, and the resistance-bearing capacity is relatively strong, and the drilling diameter can reach Φ70.

[0011] The present utility model will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0012] Embodiment
[0013] As Figure 1 、 Figure 2 and Figure 3 shown, the U-drill tooling for lathe machining provided in this embodiment includes a bottom plate 1, and a slider 2 matching the sliding dovetail groove of the lathe is formed along the length direction at the bottom of the bottom plate 1; during use, first remove the carriage on the lathe and replace the carriage with the bottom plate 1, and the slider 2 is located in the dovetail groove to realize the left and right sliding of the bottom plate 1.
[0014] An angle iron bracket 3 is fixedly installed on the bottom plate 1, and a fixing plate 4 is formed on the vertical side of the angle iron bracket 3, that is, the horizontal layer of the angle iron bracket 3 is fixedly connected to the surface of the bottom plate 1, the fixing plate 4 is formed on the vertical side of the angle iron bracket 3, the fixing plate 4 is arranged parallel to the clamping chuck of the lathe. At the same time, a fixing hole 5 coaxial with the clamping chuck of the lathe is penetrated through the fixing plate 4, and annular positioning rings are respectively formed on the outer edges on both sides of the fixing hole 5 of the fixing plate 4. Several evenly distributed flange mounting holes 6 are formed around the fixing hole 5 on the fixing plate 4, and a tool holder flange 7 is fixedly installed on the fixing plate 4; select the corresponding U-drill according to the drilling size, and select the corresponding tool holder flange 7 according to the diameter of the clamping shank of the selected U-drill. The two flange plates of the tool holder flange 7 can be quickly positioned and fixed through the positioning rings, and the two flange plates are fixed through bolts and the flange mounting holes 6, quickly completing the installation of the tool holder flange 7. The installed tool holder flange 7 is coaxial with the clamping chuck of the lathe. At this time, install the corresponding U-drill through the tool holder flange 7, and screw a locking bolt into the locking hole 8 at the top of the tool holder flange 7 after installation, so as to fix the U-drill on the tool holder flange 7. The fixed U-drill is coaxial with the clamping chuck of the lathe, and the feed length can be directly set for drilling.
[0015] The above is only the preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any modification and replacement based on the technical solution and the inventive concept provided by the present utility model should be covered within the protection scope of the present utility model.
