Description

TECHNICAL FIELD

[0001] The application relates to the field of numerical control lathe tools, in particular to a numerical control lathe composite tool. BACKGROUND

[0002] The numerical control lathe is used for machining workpieces through digital program control equipment, but at present, many numerical control lathes are single-sided machining design, and after machining of one side of the workpiece is completed, the position of the workpiece needs to be manually adjusted for machining of the other side, which is troublesome and reduces the machining efficiency of the numerical control lathe.

[0003] The structure of the product can refer to the composite tool for numerical control lathe disclosed in Chinese patent document 202221954961.2, which relates to the technical field of machine tool cutters, and comprises a tool handle rear end, the outer surface of which is detachably fixedly connected with a protective shell, a through hole is formed in the top right end of the protective shell, a support frame is fixedly connected to the top right end of the protective shell, a connecting hole is formed in the top of the support frame, a limiting rod is movably connected to the inner surface of the connecting hole, a limiting plate is fixedly connected to the outer surface of the limiting rod, a return spring is fixedly connected to the top of the limiting plate, a threaded hole is formed in the right side of the tool handle rear end, and a threaded rod is threadedly connected to the inner surface of the threaded hole. The composite tool for numerical control lathe can protect the tool, prevent the tool from falling from a high place, and thus prevent damage to the tool through the structure of the protective shell, the through hole, the support frame, the connecting hole, the limiting rod, the limiting plate, the return spring, the buffer pad and the counterweight.

[0004] When the lifting ring is produced, the inner chamfer, the outer chamfer and the end face of the lifting ring need to be machined, but in this patent, the general conventional tool does not have the function of machining the inner chamfer, the outer chamfer and the end face of the lifting ring at the same time, and needs to be machined in sequence, which reduces the work efficiency.

[0005] Now a numerical control lathe composite tool with improved efficiency is provided. CONTENT OF THE UTILITY MODEL

The knob can be rotated, thereby rotating the adjusting screw, and the position of the lifting seat can be adjusted under the action of the adjusting screw, thereby the positions of the plane tool, the inner chamfer tool and the outer chamfer tool can be adjusted according to the machining needs, and when the positions are determined, the hexagonal screw is threadedly connected to the first threaded hole, then the track circle on the first limiting groove is limited under the action of the end of the hexagonal screw, thereby reinforcing the lifting seat, facilitating subsequent machining. When three tools need to be installed, the tools are placed on the mounting grooves, then the hexagonal screw is threadedly connected to the second threaded hole, and the end of the hexagonal screw contacts the tool for stable connection, thereby facilitating dismounting and mounting.

[0009] In some embodiments, the adjusting assembly comprises an adjusting screw rotatably mounted on the inner wall of the tool groove, and the adjusting screw is threadedly connected with the lifting seat.

[0010] In some embodiments, a knob is fixedly connected to the adjusting screw.

[0011] In some embodiments, the fixing assembly comprises a first threaded hole provided on the lifting seat, a first through groove provided on the lifting seat, a first limiting groove provided on the inner wall of the first through groove, and the first through groove and the first limiting groove are in communication, and the first threaded hole corresponds to the first through groove.

[0012] In some embodiments, the first limiting groove is a track circle.

[0013] In some embodiments, the lifting seat is provided with a second threaded hole, and the planar cutter, the inner chamfer cutter and the outer chamfer cutter are respectively provided with a second through slot corresponding to the second threaded hole.

[0014] In some embodiments, the threaded slots are provided in plurality, and the plurality of threaded slots are evenly arranged circumferentially on the cutter disc body.

[0015] In some embodiments, the knob is cylindrical.

[0016] The application has the following beneficial effects:

[0017] 1. By arranging three cutter slots and a lifting seat, the cutter body simultaneously has an outer chamfer cutter, an inner chamfer cutter and a planar cutter, so that the outer chamfer, the inner chamfer and the planar surface of the lifting ring can be machined simultaneously, thereby improving the work efficiency.

[0018] 2. By arranging the adjusting screw, the knob can be rotated to rotate the adjusting screw, so that the position of the lifting seat can be adjusted, thereby the positions of the outer chamfer cutter, the inner chamfer cutter and the planar cutter can be adjusted according to the requirements, improving the practicability. By arranging the first threaded hole, the first through slot and the first limiting slot, and by arranging the hexagonal bolt, the lifting seat can be reinforced, thereby improving the subsequent stability.

[0019] 3. By arranging the second threaded hole and the second through slot, the hexagonal bolt can be used to conveniently install and dismount the outer chamfer cutter, the inner chamfer cutter and the planar cutter. BRIEF DESCRIPTION OF DRAWINGS
