Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of desk cutting round angle, specifically discloses a round angle cutting device for desk processing. BACKGROUND

[0002] In recent years, the global furniture market presents a sustained growth trend, with the acceleration of urbanization, the increase of residents' disposable income and the change of consumption concept, people's demand for furniture not only continues to rise in quantity, but also puts forward higher requirements in quality and individualization. The traditional desk round angle cutting process mainly relies on manual operation and some simple mechanical equipment, which has many limitations. Although the manual cutting method has certain flexibility, it seriously depends on the experience and skill level of workers. When workers use tools such as electric saws and files for cutting, it is difficult to accurately control the cutting angle, depth and arc, and it is easy to produce large errors.

[0003] The existing round angle cutting device for desk processing needs to use manual cutting device for round angle cutting, but in the cutting process, the hand has no supporting point, so the shaking situation will appear, so the round angle is not perfect, and the angle of each round angle cannot be guaranteed to be the same during manual cutting, so a certain error will be produced, which affects the appearance. The present application provides a round angle cutting device for desk processing which can effectively solve the above problems. UTILITY MODEL CONTENT

[0004] The utility model can guarantee that each angle of the desk top round angle cutting is the same, thereby improving the working efficiency and the appearance effect, and can also change the angle of the device cutting round angle according to the size difference of different round angles, so as to adapt to more desk round angle cutting.

[0005] The utility model is realized through the following technical schemes:

[0006] A round angle cutting device for desk processing, comprising a supporting mechanism, the supporting mechanism comprising a table plate, the top of the table plate being provided with a clamping mechanism, one side of the clamping mechanism being provided with a cutting mechanism;

[0007] As a further arrangement of the above-mentioned scheme, the cutting mechanism comprises an arc sliding rail, the top of the table plate being slidably provided with a sliding plate, the top of the sliding plate being adaptively provided with a first motor, one side of the first motor being connected with a telescopic cylinder, the output end of the first motor being fixedly provided with a rotating plate, the top of the rotating plate being adaptively provided with a second motor, the output end of the second motor being connected with a cutting head.

[0008] The first motor and the second motor are located on both sides of the circular arc slide rail, the second motor is driven to rotate in a circular arc shape by the operation of the first motor, so as to drive the cutting head to cut the table corner, thereby realizing the corner cutting work of the table. Under the assistance of the sliding plate, the telescopic cylinder can drive the first motor to move forward and backward, thereby controlling the second motor to move forward and backward, thereby realizing the function of different corner sizes.

[0009] As a further arrangement of the above scheme, the cutting mechanism further comprises a circular arc sliding plate slidingly arranged at the top of the circular arc slide rail, the bottom of the circular arc sliding plate is fixedly installed with second bearings located on both sides of the circular arc slide rail, the top of the circular arc sliding plate is slidingly connected with a transverse sliding plate, and the top is fixedly installed on the bottom of a rotating plate, the bottom of the rotating plate is fixedly installed with symmetric first bearings, and the two first bearings are in contact with both sides of the circular arc sliding plate.

[0010] Under the action of the two circular arc sliding plates, the rotating plate can stably rotate in a circular arc shape. Since the circular arc sliding plate and the transverse sliding plate are slidingly connected, when the rotating plate rotates, the length of the rotating plate on the circular arc sliding plate changes.

[0012] The telescopic rod itself has the function of telescoping, and has a certain resistance inside after being stretched to a certain length. Only when an external force stretches it will the length change. Under the action of the upper clamping shell and the lower clamping block, the upper clamping shell is located at the top of the table plate, and the lower clamping block is located at the bottom of the table plate. The device is fixed on the top of the table plate for subsequent cutting operation. The structure of the telescopic rod spring is two groups, one group is clamped on one right angle side, and the other group is clamped on the other right angle side, thereby achieving better stability.

[0013] As a further arrangement of the above scheme, the clamping mechanism further comprises a rotating shaft rotatably connected in the upper clamping shell, the outer surface of the rotating shaft is fixedly sleeved with a gear engaged with the toothed rod, the outer surface of the rotating shaft is fixedly sleeved with a ratchet wheel, the inner cavity top of the upper clamping shell is fixedly provided with symmetrically distributed fixed plates, the opposite side of the two fixed plates is rotatably connected with a ratchet tooth acting on the ratchet wheel, and the top of the ratchet tooth is fixedly installed with a pressing rod penetrating through the inside of the upper clamping shell.

[0014] Wherein, in the rotation of the rotating shaft, the ratchet wheel is driven to rotate at one side of the gear, thus, when the gear stops rotating, the ratchet can be clamped into the ratchet wheel to limit its reverse rotation, so as to fasten the upper clamping shell and the lower clamping block to clamp the table board.

[0015] As a further arrangement of the above-mentioned scheme, the supporting mechanism further comprises table legs fixedly installed at the bottom of the table board, the top of the table board is provided with and symmetrically distributed vertical columns, the opposite sides of the two vertical columns are fixedly installed with and symmetrically distributed fixed circular arc plates, and the top of each fixed circular arc plate is connected with a handle.

[0016] Wherein, one end of the telescopic rod is fixedly installed at one side of the vertical column, one end of the telescopic cylinder is fixedly installed at one side of the fixed circular arc plate, and under the action of the two vertical columns, the cutting mechanism can stably round-cut the table corner, and under the action of the handle, the device can be conveniently taken off the table board and conveniently carried.
