[0005] In summary, the present invention provides a cutting device for mechanical processing to solve the above problems. Utility Model Content

[0006] In view of the shortcomings of the prior art, the purpose of the utility model is to provide a cutting device for mechanical processing, which has the advantages that the cutting knife can be easily removed and replaced or sharpened for reuse, and the cutting knife can be easily disassembled and replaced, and it is easy to sharpen the cutting knife regularly to maintain its cutting effect.

[0007] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0008] A cutting device for mechanical processing includes a cutting table, a cutting knife and a motor. A positioning assembly is fixedly installed below the cutting table. The positioning assembly includes a support frame, an anti-slip plate, a support column, a rotating head and a screw rod. A square groove is provided inside the anti-slip plate, an inner groove is provided on the top of the square groove, a clamping groove is provided on one side of the anti-slip plate, an annular groove is provided outside the rotating head, and a clamping plate is threadedly mounted on the outer surface of the screw rod.

[0009] By adopting the above technical solution, the card slot and the inner groove are connected. After the anti-slip plate is inserted into the annular groove, even if the rotating head is driven to rotate by the support column, it will not affect the connection between the card plate and the rotating head. The anti-slip plate can be installed on one end of the support column by being clamped together, thereby fixing the cutting knife on the support column.

[0010] The utility model is further configured as follows: the support frame is fixedly installed on the bottom of the cutting table, and the anti-drop plate is hinged to one side of the support frame through a hinge.

[0011] By adopting the above technical solution, four supporting legs are fixed to the bottom of the cutting table, and the height of the supporting legs is greater than the length of the extension table in the extension assembly to prevent the extension table from affecting the balance of the cutting table after being folded.

[0012] The utility model is further configured as follows: the support column is rotatably installed inside the support frame, and the motor is fixedly installed on one side of the support frame.

[0013] By adopting the above technical solution, one end of the motor output shaft is fixedly connected to the support column, and the motor is electrically connected through existing technology and an external control switch. The support column is square in the middle and cylindrical at both ends. The square shape is locked with the square hole in the cutting knife, making it convenient for the cutting knife to be driven by the support column to rotate.

[0014] The utility model is further configured as follows: one end of the support column is rotatably mounted on one side of the rotating head, the screw rod is rotatably mounted inside the square groove, and the clamping plate is slidably mounted inside the inner groove.

[0015] By adopting the above technical solution, the inner groove limits the clamping plate. When the screw rod rotates, the clamping plate moves up and down along the guide of the inner groove until the clamping plate moves into the annular groove to connect the anti-slip plate and the rotating head.

[0016] The utility model is further configured as follows: both sides of the cutting table are equipped with extension components, and the extension components include an extension table, an L-shaped support plate and a positioning screw.

[0017] By adopting the above technical solution, the extension table can be folded down when the device is transported, which reduces the space occupied by the device and makes it more convenient to move or store the device. The L-shaped support plate is hinged to the support leg through a hinge, and one end of the connecting column is fixed and supported by the L-shaped support plate.

[0018] The utility model is further configured as follows: the stretching platform is hinged to one side of the cutting platform through a hinge, two grooves are arranged at the bottom of the stretching platform, and connecting columns are rotatably installed inside the grooves.

[0019] By adopting the above technical solution, when the connecting column is supported on the upper L-shaped support plate on the supporting leg, the stretching platform is in an unfolded state, preventing the stretching platform from folding into a vertical state when supported on the lower L-shaped support plate, and the state of the stretching platform can be fixed.

[0020] The utility model is further configured as follows: a positioning hole is opened at one end of the connecting column, and the positioning screw is threadedly installed inside the L-shaped supporting plate.

[0021] By adopting the above technical solution, the positioning screw is screwed into the positioning hole to connect one end of the connecting column and the L-shaped support plate, so that the L-shaped support plate is located at the lower part of one end of the connecting column.

[0022] In summary, the beneficial technical effects of the utility model are:

[0023] By rotating the screw rod to move the clamping plate out of the annular groove, the connection between the rotating head and the anti-drop plate can be released, the anti-drop plate can be rotated out of the rotating head, and the cutting knife can be removed and replaced with a new one or sharpened and reused. It is convenient to disassemble and replace, and it is easy to sharpen the cutting knife regularly to maintain its cutting effect.
