It is laborious to manually hold the square tube, and the shaking of the square tube during deburring affects the operation. It is also not easy to collect the burrs after grinding to reduce the impact of pollution on the surrounding environment. Summary of the Invention

[0005] The purpose of this invention is to provide a deburring device for the inner wall of square tubes to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A deburring device for the inner wall of a square tube includes a base, on which support columns are symmetrically arranged on the upper surface. A deburring component for grinding is provided on the support column on the left side, and a clamping frame for fixing the square tube is provided on the support column on the right side. A storage box for collecting burr debris is provided between the two support columns.

[0008] Each storage box has a baffle on the top, and a through window on the front baffle. A slot is provided at the bottom of the front face of the storage box, and a collection drawer is provided in the slot.

[0009] The clamping frame has a hollow center, and a screw hole is provided at the center of the upper surface of the clamping frame. A screw rod is provided in the screw hole, a handwheel is provided at the top of the screw rod, and a clamping plate is provided at the bottom of the screw rod.

[0010] The deburring assembly includes a positioning plate and a trapezoidal seat that slides on the bottom of the positioning plate. A trapezoidal groove is provided at the bottom of the positioning plate corresponding to the trapezoidal seat. A motor is provided on the lower surface of the trapezoidal seat. A detachable cone is coaxially connected to the output shaft of the motor. Several wire brushes are provided on the outer wall of the cone.

[0011] Furthermore, the bottom of each support column is welded and fixed to the top of the base, and the distance between two support columns is adapted to the length of the outer wall of the storage box.

[0012] In this invention, the support columns support the clamping frame and the deburring assembly, which facilitates the removal of burrs from the inner wall of the square tube. The storage box is installed between the two support columns to collect the burr debris from the square tube end, reducing the debris from falling around and affecting the surrounding environment.

[0013] Specifically, the bottom of the baffle is welded and fixed to the top of the storage box, the outer wall of the through window is bonded and fixed to the inner wall of the opening on the baffle, and the width of the inner wall of the slot is adapted to the width of the outer wall of the collection drawer.

The outer wall of the collection drawer is equipped with a handle, which helps to pull the drawer out and collect the burrs and debris. The baffle blocks the space above the storage box to prevent debris from splashing out from the top of the storage box and affecting the surrounding environment.

[0015] It should be noted that the clamping frame is inclined, with the left end lower than the right end. The bottom of the clamping frame is welded and fixed to the top of the support column on the right side. The screw is threadedly connected to the screw hole.

The width of the outer wall of the clamping plate is adapted to the length of the hollow area of ​​the inner wall of the clamping frame. Rubber pads are provided on the opposing sides of the clamping plate and the inner wall of the clamping frame.

[0016] In this invention, the square tube is inserted from the right end of the clamping frame, and with the help of turning the handwheel, the clamping plate is adjusted to make contact with the upper surface of the square tube. With the help of two rubber pads, the position of the square tube is fixed by friction. The left end of the clamped square tube is lower than the right end. Under the action of gravity, the burrs on the inner wall of the left end are polished and removed, and then it falls into the collection drawer.

[0017] Furthermore, the left end of the positioning plate is welded and fixed to the left support column, the positioning plate is inclined, the positioning plate is parallel to the clamping frame, and the bottom of the positioning plate is tightly fitted to the top of the baffle.

[0018] In this invention, the positioning plate is tilted and corresponds to the clamping frame, which helps the motor mounted on the positioning plate to move along the direction of the positioning plate, so that the cone extends into square tubes of different sizes. The cone extends into the square tubes to different depths, and the burrs inside the ports of square tubes of different sizes are contacted and ground, which helps to stably perform deburring and mating.

[0019] It is worth adding that the electric push rod is fixedly connected to the support column on the left side by screws, the telescopic arm of the electric push rod passes through the support column on the left side and extends into the trapezoidal groove, and the telescopic arm is fixedly connected to the left end of the trapezoidal seat by screws.

[0020] In this invention, the electric push rod is connected to an external power source via a wire. When the control switch on the outer wall of the electric push rod is activated, the telescopic arm extends and pushes the trapezoidal seat upward along the positioning plate, thereby extending the cone into the square tube where the burrs on the inner wall of the port need to be removed.

[0021] In addition, the width of the outer wall of the trapezoidal seat is adapted to the width of the inner wall of the trapezoidal groove. The top of the motor is fixedly connected to the bottom of the trapezoidal seat by screws. The wire brushes are distributed in a ring at equal intervals, and one end of each wire brush is welded and fixed to the cone. The cone is inserted into the output shaft end of the motor through a pin and fixedly connected by screws. The central axis of the cone corresponds to the central axis of the clamping frame.

[0022] In this invention, the motor is connected to an external power source via a wire. The control switch on the outer wall of the motor is activated, causing the output shaft of the motor to rotate and drive the cone to rotate. With the cooperation of multiple wire brushes, the burrs on the inner wall of the square tube port are removed. The cone is conical in shape and gradually narrows from the left end to the right end, which helps the cone to extend into the interior of square tubes of different sizes to grind and remove burrs from the inner wall port of the square tube.

The telescopic arm is fixedly connected to the left end of the trapezoidal seat 42 by screws.

[0050] In this utility model, the electric push rod 41 is connected to an external power source through a wire. When the control switch on the outer wall of the electric push rod 41 is activated, the telescopic arm extends and pushes the trapezoidal seat 42 to move upward along the positioning plate 40, thereby enabling the cone 43 to extend into the square tube where the burrs on the inner wall of the port need to be removed.
