Description

Technical Field

[0001] The utility model relates to the technical field of metal cutting machine tools, in particular to a metal cutting machine tool that can be quickly clamped. Background Art

[0002] Metal cutting is a material removal and forming method in metal forming processes. The metal cutting process is a process of interaction between the workpiece and the cutting tool. The cutting tool removes excess metal from the workpiece to be machined and, on the premise of controlling productivity and cost, enables the workpiece to obtain geometric accuracy, dimensional accuracy, and surface quality that meet design and process requirements.

[0003] Most of the existing technologies adopt a metal cutting machine tool that can be quickly clamped, such as the one disclosed in the patent with the publication number CN214641785U. This technology includes a machine body, a machine cover, a tool holder, a fixture, a controller, a heat dissipation device, a liquid tank, and a support block. The machine cover is slidably fitted on the left side of the front end of the machine body. The heat dissipation device is riveted to the right side of the controller. The liquid tank is embedded at the bottom of the machine body. The support block is fitted into the lower end of the liquid tank. This technology presses the tool by generating pressure on the tool through the inner core of the induction bolt. Since there is a gap between the outer shell and the inner core of the induction bolt, tool damage is avoided. However, there are still problems in the use process due to structural limitations in the above technology:

[0004] During the cutting operation, cutting waste chips will be generated at the machining location of the metal workpiece. At the same time, the cutting waste chips will fly along the tangential direction of the rotation of the fixture. However, the above technology does not collect the cutting waste chips centrally, resulting in the cutting waste chips flying everywhere, which is not conducive to the subsequent cleaning of the cutting waste chips. Summary of the Utility Model

[0005] The purpose of the utility model is to solve the problem that it is not easy to clean the cutting waste chips in the existing technology, and to provide a metal cutting machine tool that can be quickly clamped.

[0006] To achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A metal cutting machine tool that can be quickly clamped, including a machine body, on which are provided:

[0008] A limit fixture and a cutting tool. The limit fixture is installed at the upper end of the machine body, and the cutting tool is arranged above the machine body;

[0009] A cavity and a long groove. The cavity is opened in the machine body, and the long groove is opened at the upper end of the machine body and is connected to the cavity;

[0010] A rotating plate, a guiding arc surface and a side-end moving plate. The rotating plate is rotatably mounted in the long groove. The guiding arc surface is formed at the lower end of the rotating plate. The side-end moving plate is arranged at the side end of the machine body. The rotating plate and the side-end moving plate cooperate to shield the limiting fixture.

[0011] Preferably, a truss is fixedly connected to the upper end of the machine body, and a guiding groove is formed in the truss.

[0012] Preferably, the cutting tool is slidably sleeved in the guiding groove. A cleaning port is formed in the machine body, and the cleaning port is used for cleaning the cavity.

[0013] Preferably, a movable cavity is formed in the rotating plate. An extension plate is slidably sleeved in the movable cavity. A telescopic cylinder is fixedly connected in the movable cavity, and the output end of the telescopic cylinder is fixedly connected to the extension plate.

[0014] Preferably, a discharge hole is formed in the guiding arc surface, and the discharge hole is communicated with the movable cavity.

[0015] Preferably, a first cylinder and a second cylinder are respectively fixedly installed on the guiding groove and the truss. The output ends of the first cylinder and the second cylinder are respectively fixedly connected to the cutting tool and the side-end moving plate.

[0016] Compared with the prior art, the present utility model has the following advantages:

[0017] In the present utility model, by driving the rotating plate to rotate, the guiding arc surface faces the limiting fixture. At the same time, the side-end moving plate abuts against the rotating plate, thereby shielding the metal workpiece. The cutting waste chips splash along the rotation normal direction of the limiting fixture and, under the guidance of the guiding arc surface, fall into the cavity, so that the cutting waste chips are centrally collected, facilitating subsequent centralized cleaning of the cutting waste chips.

[0025] The machine body 1 is also provided with a rotating plate 4, a guiding arc surface 5 and a side-end moving plate 6. The rotating plate 4 is rotationally connected to the long groove through a rotating shaft. A fixing motor is fixedly installed at the side end of the long groove, and the output end of the fixing motor is fixedly connected to the rotating shaft. The rotating plate 4 is driven to rotate by the output end of the fixing motor, so that the guiding arc surface 5 is located in the tangential direction of the rotation of the limit fixture 2. At the same time, the guiding arc surface 5 is opened at the lower end of the rotating plate 4. The side-end moving plate 6 is arranged at the side end of the machine body 1. After the guiding arc surface 5 faces the limit fixture 2, the side-end moving plate 6 is moved to make the rotating plate 4 abut against the side-end moving plate 6 to block the limit fixture 2, and under the guidance of the guiding arc surface 5, the cutting waste chips fall into the cavity from the long groove.
