Description

Technical Field

[0001] This invention relates to the field of machining technology, and more specifically to a burr removal device and method for machining. Background Technology

[0002] Modern manufacturing is still dominated by machining, including turning and milling. Machined parts are ubiquitous in our lives. These parts, which come in various shapes, often have sharp burrs left on their edges after machining. The usual practice is to use a deburring knife or sandpaper to grind away the sharp burrs. Manual deburring is not only easy to cause injury, but also very easy to scratch the workpiece, which is time-consuming and laborious. With the advancement of technology, deburring machines or devices have also been developed to remove burrs. However, these devices or machines can generally only remove burrs from plate or cylindrical parts. It is still relatively difficult to remove burrs from rotating parts.

[0003] Therefore, in order to overcome the above-mentioned defects, it is urgent to develop a burr removal device and method for machining that can overcome these defects. Summary of the Invention

[0009] The first actuator is mounted on the first drive mechanism;

[0010] The second actuator is mounted on the second drive mechanism;

[0011] In this process, a workpiece is placed between the first actuator and the second actuator. The adjustable clamping mechanism drives the second actuator to move so as to clamp the workpiece with the first actuator. Then, the first drive mechanism and the second drive mechanism are driven to control the second actuator and the first actuator to perform frictional motion with the end face of the workpiece to remove burrs.

At this time, the friction components rotate around the stud to a suitable angle and stick to the cylindrical workpiece 82 through the flexible movement of the tension spring. Then, the motor is started to drive the transmission cylinders 511 and 611, which in turn drive the friction components to rotate along the inner diameter edge of the upper and lower end faces of the cylindrical workpiece 82. The burrs are removed by the friction movement of the sandpaper Z5 with the cylindrical workpiece.

After adjustment, the movable column 31 is moved down to press the conical workpiece by rotating the handle 33. At this time, the friction components rotate around the stud to a suitable angle and fit tightly against the conical workpiece through the flexible movement of the tension spring. Then, the motor is started to drive the transmission cylinders 511 and 611, which in turn drive the friction block assembly to rotate along the outer diameter edge of the upper and lower end faces of the conical workpiece 83. The burrs are removed by the friction movement of the sandpaper Z5 against the conical workpiece.

[0089] Step S3: By driving the first drive mechanism and the second drive mechanism, the second actuator and the first actuator are controlled to perform frictional motion with the end face of the workpiece to remove burrs.

[0090] Further, the clamping step S2 includes:

[0091] By rotating the handle, the sleeve drives the movable column to move along the axial direction of the sleeve, thereby driving the second drive mechanism and the second actuator to move to clamp the workpiece.

[0092] Furthermore, the removal step S3 includes:

[0093] The rotating positioning plate drives the friction assembly to move radially through the arc positioning groove on the positioning plate so that the friction assembly is attached to the end face of the workpiece.

[0094] The motor shafts that drive the first and second drive mechanisms drive the transmission assembly to rotate, causing the friction assembly to perform frictional motion on the end face of the workpiece.

[0095] In summary, this invention can completely replace manual removal of residual burrs after machining of rotating parts. It is simple to operate, has high removal efficiency, and avoids scratches on the workpiece during manual burr removal.

3. The burr removal device as described in claim 1, characterized in that, The first driving mechanism includes: A first motor, the motor shaft of which is connected to the first actuator; A support member is mounted on the chassis, and the first motor is mounted on the support member.

4. The burr removal device as described in claim 2, characterized in that, The second drive mechanism also includes: The connector has one end connected to the second motor and the other end connected to the movable column.

5. The burr removal device as described in claim 4, characterized in that, The transmission assembly includes: A transmission cylinder, one end face of which is keyway connected to the motor shaft; Multiple first transmission rods are spaced apart along the circumferential surface of the transmission cylinder and connected to the outer wall of the transmission cylinder; Multiple second transmission rods are correspondingly connected to the first transmission rod. Each second transmission rod has a guide groove. One end of the friction assembly extends into the guide groove through the arc positioning groove. The guide groove guides the movement direction of the friction assembly. When the transmission assembly rotates, it drives the friction assembly to slide in the guide groove through the arc positioning groove, so that the friction assembly rotates axially.

6. The burr removal device as described in claim 5, characterized in that, Each of the aforementioned friction components includes: A connecting post has an annular protrusion on its outer side, the annular protrusion being installed in the arc positioning groove, and one end of the connecting post being located in the guide groove; A T-shaped connecting rod is connected to the other end of the connecting column, and the T-shaped connecting rod has two first pull rings; A pad is provided with two lugs and two second pull rings. The T-shaped connecting rod is connected to the two lugs by studs and connected to the first pull ring and the second pull ring by two elastic elements respectively. An elastic pad is installed on the bottom of the pad plate; Sandpaper is mounted on the pad and covers the elastic pad.

7. A method for removing burrs in machining, characterized in that, The burr removal apparatus applied to any one of claims 1-6, the burr removal method comprising: Preparation steps: Place a workpiece between the first actuator and the second actuator; Clamping step: The adjustable clamping mechanism drives the second actuator to move so as to clamp the workpiece with the first actuator; Deburring step: By driving the first drive mechanism and the second drive mechanism, the second actuator and the first actuator are correspondingly controlled to perform frictional motion with the end face edge of the workpiece to remove burrs.

8. The burr removal method as described in claim 7, characterized in that, The clamping step includes: By rotating the handle, the sleeve drives the movable column to move along the axial direction of the sleeve, thereby driving the second drive mechanism and the second actuator to move to clamp the workpiece.
