Description

Technical Field

[0001] This utility model belongs to the field of sheet metal processing technology, specifically relating to a mechanical product sheet metal cutting edge burr removal device. Background Technology

[0002] During sheet metal cutting, burrs often form at the cut edges due to various factors such as tool wear, cutting speed, and sheet material. These burrs not only affect the product's appearance but can also pose safety hazards during use, such as scratches, wear, or impaired assembly precision. Especially in industries with extremely high surface quality requirements, such as precision instrument manufacturing and electronic product casing manufacturing, the presence of burrs can lead to products being deemed unqualified, resulting in material waste and increased production costs.

[0003] Traditional methods for removing burrs from the edges of cut boards mainly include manual sanding and mechanical sanding. While manual sanding is flexible, it is inefficient, requiring operators to hold the sander for extended periods, resulting in significant physical exertion. Furthermore, hand-held sanding makes it difficult to guarantee consistent quality. Mechanical sanding, on the other hand, is more efficient, but often requires various sizes of sanding tools and fixtures to accommodate boards of different thicknesses and dimensions, making the process complex and costly. Utility Model Content

[0004] To address the above problems, the purpose of this utility model is to provide a burr removal device for the cutting edges of sheet metal products, which solves the problems that traditional burr removal methods are mostly manual grinding, which is inefficient and makes it difficult to ensure consistent processing quality, and requires various specifications of grinding tools and fixtures when grinding sheets of different thicknesses, which is complicated and costly.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a deburring device for cutting sheet metal edges of mechanical products, comprising a base, a support frame mounted on the base, multiple ball bearings rotatably mounted on the base inside the support frame, a controller and a guide rod mounted on the support frame, the support frame rotatably connected to the rear end of a rotating frame in an adaptive conveying assembly via a pin shaft, an output shaft rotatably mounted on the front end of the rotating frame, a pressure wheel mounted on the output shaft, the output shaft being driven by a motor via a belt drive mechanism, the motor being mounted on the rotating frame, a connecting seat also mounted on the rotating frame, the connecting seat being rotatably connected to one end of an electric push rod via a pin shaft pressure sensor, the other end of the electric push rod being rotatably connected to the support frame via a pin shaft, and a sliding grinding assembly slidably mounted on the guide rod.

[0006] The beneficial effects of this utility model are as follows: by cooperating with the pin-type pressure sensor and the electric push rod, the pressure roller can automatically adapt to and stably press the plate of different thicknesses, thereby improving the conveying stability and polishing efficiency; the sliding grinding component with sliding adjustment combined with the ball bearing that provides rolling support for the plate not only ensures the flexibility of polishing, but also facilitates precise processing according to the specific conditions of the plate edge.

[0007] In order to flexibly adjust the angle and position of the sheet metal on the machine base;

[0008] As a further improvement to the above technical solution: the top surface of the base is provided with a rolling groove for rotating and mounting ball bearings, and the ball bearings are evenly distributed on the base.

[0009] The beneficial effects of this improvement are: the evenly distributed balls can provide rolling support for the sheet material, allowing the sheet material to move in different directions to adjust its position and angle.

[0010] To facilitate the installation and removal of ball bearings and ensure the stability of ball bearing operation;

[0011] As a further improvement to the above technical solution: the rolling groove is a hemispherical groove, the top surface of the base is provided with an embedded groove for mounting a cover plate, the top surface of the cover plate is not higher than the top of the ball, and the cover plate is provided with a through groove for rotating the cover to be mounted on the outside of the ball.

[0012] The beneficial effects of this improvement are: the cover plate can be connected to the machine base by bolts, thereby limiting the position of the balls that are rotatably installed in the rolling groove, ensuring the stability of the ball position, and can be quickly disassembled, thus facilitating personnel to clean the balls and rolling groove.

[0013] In order to achieve self-adjustment of the clamping force of the adaptive conveying component;

[0014] As a further improvement to the above technical solution: the controller includes a control switch, a PLC and a relay, and the controller is electrically connected to a pin-type pressure sensor and an electric actuator.

[0015] The beneficial effects of this improvement are as follows: during the extension of the electric push rod, the pin-type pressure sensor provides feedback on the downward pressure, and the PLC module in the controller receives and processes the electrical signal from the pin-type pressure sensor. When the pressure value reaches the set threshold, the electric push rod is controlled to stop extending, thereby pressing the plate with appropriate pressure.

[0016] To ensure the stable rotation of the motor-driven pressure rollers for conveying the sheet material;

[0017] As a further improvement to the above technical solution: the driving pulley in the belt drive mechanism is mounted on the output shaft of the motor, and the driven pulley in the belt drive mechanism is mounted on the output shaft.

[0018] The beneficial effects of this improvement are: the motor can drive the output shaft to rotate stably through the belt transmission mechanism, thereby driving the pressure wheel to rotate and convey the plate.

[0019] To ensure the stability of the sliding grinding component's movement;

[0020] As a further improvement to the above technical solution: the number of guide rods is two, the sliding grinding assembly includes a movable seat, the movable seat has a through hole for sliding connection, a grinding motor is installed on the movable seat, the output shaft of the grinding motor is connected to the top end of the rotating shaft, and a grinding wheel is installed at the bottom end of the rotating shaft.

[0023] As a further improvement to the above technical solution: handles are installed on both sides of the movable seat.

[0024] The beneficial effect of this improvement is that the operator can hold the handle and drag and slide the entire polishing component with ease.

[0025] The parts of the device not covered herein are the same as or can be implemented using existing technologies. Attached Figure Description

[0031] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of the present invention in any way.

A motor 52 is connected to the rotating frame 51, which is also equipped with a connecting seat 56. The connecting seat 56 is rotatably connected to one end of an electric push rod 58 via a pin-type pressure sensor 57. The other end of the electric push rod 58 is rotatably connected to a support frame 2 via a pin. A sliding grinding assembly 8 is slidably installed on the guide rod 6. Through the cooperation of the pin-type pressure sensor 57 and the electric push rod 58, the pressure roller 55 automatically adapts to and stably presses the plates of different thicknesses, thereby improving the conveying stability and polishing efficiency.The sliding polishing assembly 8, with its adjustable sliding mechanism, combined with ball bearings 4 providing rolling support to the sheet metal, ensures both polishing flexibility and allows for precise processing based on the specific conditions of the sheet metal edges. The top surface of the base 1 has a rolling groove 11 for rotatably mounting the ball bearings 4. The ball bearings 4 are evenly distributed on the base 1, providing rolling support to the sheet metal and allowing it to move in different directions to adjust its position and angle. The rolling groove 11 is a hemispherical groove. The top surface of the base 1 has an embedded groove 12 for mounting a cover plate 3. The top surface of plate 3 is no higher than the top of ball 4. A through groove is provided on the cover plate 3 for rotating the cover onto the outside of ball 4. The cover plate 3 can be connected to the machine base 1 via bolts, thereby limiting the position of ball 4, which is rotatably mounted in the rolling groove 11, ensuring the stability of ball 4's position. It can also be quickly disassembled, facilitating cleaning of ball 4 and rolling groove 11. The controller 7 includes a control switch, PLC, and relay. The controller 7 is electrically connected to a pin-type pressure sensor 57 and an electric push rod 58. During the extension of the electric push rod 58, the pin... The pressure sensor 57 provides feedback on the downward pressure. The PLC module in the controller 7 receives and processes the electrical signal from the pin-type pressure sensor 57. When the pressure value reaches a set threshold, it controls the electric push rod 58 to stop extending, thereby pressing the plate with appropriate pressure. The driving pulley in the belt drive mechanism 53 is mounted on the output shaft of the motor 52, and the driven pulley in the belt drive mechanism 53 is mounted on the output shaft 54. The motor 52 can drive the output shaft 54 ​​to rotate stably through the belt drive mechanism 53, thereby driving the pressing wheel 55 to rotate and convey the plate. The sliding polishing assembly 8 comprises two guide rods 6. A movable base 81 has a through hole for sliding connection to the movable base 81. A polishing motor 82 is mounted on the movable base 81. The output shaft of the polishing motor 82 is connected to the top end of a rotating shaft 83. A polishing wheel 84 is mounted on the bottom end of the rotating shaft 83. The sliding polishing assembly 8 can move stably under the support and guidance of the two guide rods 6. Handles 85 are mounted on both sides of the movable base 81, allowing the operator to easily pull the entire sliding polishing assembly 8 by gripping the handles 85.

[0034] The working principle of this technical solution is as follows: In the initial state, the electric push rod 58 retracts to its minimum stroke. The operator places the sheet metal on the machine base 1, so that the sheet metal is supported by the rolling of the ball bearings 4, and adjusts the angle of the sheet metal to facilitate subsequent cutting. Then, the operator controls the electric push rod 58 to extend through the controller 7. When the electric push rod 58 extends, it drives the front end of the rotating frame 51 to rotate downward through the pin-type pressure sensor 57, so that the pressure roller 55 is in contact with the surface of the sheet metal. The pin-type pressure sensor 57 feeds back the downward pressure, which is received and processed by the PLC module in the controller 7. The electrical signal from the pin-type pressure sensor 57 controls the electric push rod 58 to stop extending when the pressure value reaches the set threshold, thereby pressing the plate with appropriate pressure. Then, the operator controls the start motor 52, which drives the output shaft 54 ​​to rotate through the belt drive mechanism 53, thereby causing the pressing wheel 55 to rotate and move the plate to the rear of the adaptive conveying component 5. The operator starts the grinding motor 82, holds the handle 85 and slides to adjust the position of the sliding grinding component 8, so that the rotating grinding wheel 84 is against the long cut edge of the plate to grind and remove the burrs on the plate.
